Application filedSeptcmber 22, 1922. Serial No. 589,794.

To all 417720712 it may concern.

Be it knownthat I, ERASTUS'E. WINKLEY, a citizen of the United States, residing at Lynn, in the countyof Essex and State of li-fassachusetts, have invented certain new and useful Improvements in Heel-Building Machines, of which the following is a specification. j

This invention relates to heel building ma chines and more particularly to such machines for producing a low heel-section. I

Certain types of heels are built froni'heelsections comprising (1) abase lift and a plurality oflifts superposed thereon, all of which are composed of a leather substitute, (2) a so-called'leather unit or section com-' prising one or more lifts of j a medium quality of leather, and (3) atop lift, of a fine quality of leather. The leather unitvaries from one-eighth to three-eighths inches, approximately, in thickness and is usually con'xpcsed of two or more layers of leather ofditlerent grades, or of leather and rubber, preferably secured together by paste. The

" present invention is particularly useful in building heel-sections or units of this character.

The general object of the present invention is to improveheel lift assembling mechanisms in amanner to provide a machine particularly adapted for building heel-sections for use in manufacturing heels of, the character above indicated.

Other objects of the invention are to provide a machine of the character described by means of which'the assembling of the lifts in the required order will be insured without the necessity of constant careful attention and thought upon the part of the operator, and to provide an efficient and reliable machine which. is of simple and r gged constructionpand one which is en. tirely automatic in operation after the component lifts have been supplied thereto.

With the above objects in view, the pres ent invention contemplates the provision, in a machine of the general character above indicated, of an endless carrier, which may conveniently be a rotary turret having a plurality of equally spaced lift-holding recesses or pockets, the number of which 1s one greater than somemultiple of the number of the component layersfor lifts to be asscml; led in each heel-sectlon or unit; means for advancing the carrier step by step together;means for discharging. the assembled heel-sections from the pockets; and means for receiving the discharged sections and holding them under pressure during the setting of the paste. It-is within the scope of the invention to secure the component parts of the heel-section together in any convenient manner by any suitable securing agent, and while paste is preferred, those skilled in the art will recognize that its use is not essential.

In accordance with the illustrated embodimentof the invention, the machine is so constructed as to build heel-sections composed of two lifts. In such illustrated ma chine a rotary carrier or turret is provided, having five equally spaced lift-holding recesses or pockets, which is rotated intermit tent-1y through steps equal to twice the angular distance between the pockets. During tor. An automatic pasting device is located at the station occupied by one of the pockets adjacent the receiving stations for applying paste to the lift when at said station, while the pocket at the station next beyond the p'astin station is positioned in registry with a tuhe-like'press and a reciprocating plunger is provided for delivering the assembled heel-sections to the press.

While a machineconstructed as above described has been selected for illustrative purposes, the invention is not limited to such posed'of three or more lifts. For example,

if a heel-section composed of three lifts is to be built, the carrier is provided with seven lift receiving recesses or pockets and is advanced through steps equal in length to three times the angular distance between the pockets, in such a case, two pasting devices being employed and three lifts being supplied at each period of rest. For building a heel section composed of four layers or lifts, the carrier is provided with nine lift receiving recesses or pockets and is advanced through steps equal in length to four times the angular distance between the pockets, three pasting devices being employed and four lifts being supplied at each period of rest.

It will be observed. that the description just given of the construction of the machine for building heel-sections of two, three or four lifts relates to a design, in each instance, having the number of lift pockets equal in number to twice the number of lifts: in the unit beingbuiltv plus one. Calling the number of lifts in the unit a, the number of-pockets is expressed by the formula 2n+1. This construction is preferable because with it the feed step is of the minimum length and this results in the greatest output. As previously described, the scope of the invention includes a design in which the number of lift pockets may be any multi ple of the number of lifts in the unit, the feed step being correspondingly increased in length. For example, a two lift unit may be manufactured with nine, or 4m+1, turret pockets, but the feed here must be through four pocket spacingsinsteac of two. Calling m the variable multiplier of the number of lifts in the unit, then the number of pockets to be provided on the carrier may be expressed broadly by the formula mn-j-L lVhatever the number of lift pockets the number of pasting devices would, of course,

always be n1.

The present machine, as will hereinafter appear, is so designed that such changes in:

the construction and arrangement of parts as may be necessary to adapt the machlne to make a heel-section comprising more than two lifts, can readily be made without any variation from the principle of operation.

To the accomplishment of the above objects and such others .as may hereinafter appear, the features of the present invention consist in certain novel constructions, arrangements and combinations of parts hereinafter described and more particularly point-ed out in the appended claims, the advantages of which will be apparent to those skilled in the art.

The features of the invention will be readily understood from the accompanying drawings illustrating the preferred form of the invention, in which Figure 1 is atop plan view of a machine constructed in accordance with the present invention; Fig. 2 is a view in side elevation, looking from the right in Fig. 1, with the paste pot removed and certain portions of the machine being broken away; Fig. 3 is a sectional view taken on the line 3-3 of Fig. 2 Fig. l is a sectional View taken on the line d-l of Fig. 3; Fig. 5 is a view in front elevation of a portion of the cement applying mechanism; Fig. 6 is a view similar to Fig. 5 showing the parts in a different position; Fig. 7 is a view in side elevation of the mechanism shown in Fig. 6; Fig. 8 is a detailed view in front elevation of the cement reservoir; Fig. 9 is a view partially in section on the line 99 of Fig. 3 and partially in front elevation, showing particularly the tube-like press for bolding the assembled heel sections during the setting of the paste; Fig. 10 is a top plan view of the press shown in Fig. 9; Fig. 11 is a detailed sectional view taken substantially on the line 11-11 of .Fig. 10; Fig. 12 is a detailed view of a portion of the means for adjusting the size of the press, the view being taken substantially on the line 12-12 of Fig. 9; Fig. 13 is a sectional view of a portion of the rotatable turret, the left half of the view; being taken substantially on the line 1'313 of F ig. 1, and the right half of the view being taken substantially on the line 1?

The illustrated machine comprises, in general, a supporting frame 20 (Fig. 2) upon which the various parts of the machine are mounted, a stationary annular feed table 22 (see also. Figs. 1 and 3) and a carrier or turret 24, the latter adapted to be intermittently rotated in a horizontal lane just abovev the central opening in the feed table 22 and having a plurality of lift engaging and alining devices overlying the table and serving in conjunction therewith to provide five equally spaced apart lift receiving pockets 26 (Fig. 1), two of which are located during the periods of rest of the turret at two lift-receiving stations 28 and 30, whilea third pocket is located at a pasting station 32 and a fourth at a discharge station 34:; means, including a feed pawl 36 (Fig. 3) and an oscillatory pawl-carrier .disk 38, for rotating the turret 24: to ad- Vance the lifts step-by step in a circular path around thefeed table; an automatic.

=- tion in the pocket at the discharge station andforce it downwardly through a liftsha ed opening 14 (Fig. 3) in the feed table; and a tube-like press 46 .(Fig. 2) vertically arranged beneath the feed table 22 1: with its upper end closely adjacentv the opening 14 to receive the successively discharged heel sections and hold them under pressure during the setting of the paste.

The supporting frame of the machine comprises a base (Fig. 2), a tubular pedestal 52 and a forwardly projecting hollow head5t, all of which are rigidly secured together by means of vertical tie bolts 56 extending through the pedestal 52. r The forwardly projecting portion of the head 5% supports a substantially semicircular braoketf58 (Fig, 3) to which the feed table.

22 is rigidly secured by means of screws 60.

The various movements of the operating parts are derived from cams 62, 64, 66 and 68, secured upon a horizontal cam shaft 70 (Figs. 1 and 2) that is-journaled in bearings formed within brackets 72 rising from the rear portion of the head 54. The cam shaft 5 70 is driven by a belt 7 1 which passes over a pulley 7 6 that is secured to one end of the cam shaft and over a pulley 78 that is loose ly mounted upon one end of a horizontal driving shaft 80, the latter being parallel to the cam shaft 7 0 and being journaled in bearing brackets 82rising from the base 50. Normally the pulley 7 8 is connected to rotate with the driving shaft by means of a clutch comprising a clutch member 86 carried by the pulley' 78 and a clutch disk 88 that is'splined to the driving shaft 80. The shaft 80 may. be driven from any suitable source of power through the agency of the usual fast and loose pulleys 90 and 92 at the end of the driving shaft opposite the pulley 78.

The clutch member 86 (Fig. 14) consists of a ring arranged in a vertical plane adjacent the inner side of the pulley 8 and pivotally connected with said pulley by means of a stud 96. Projecting radially from the outer edge of the member 86 at a point diametrically opposite the pivot stud .96is a lug 98 which is adapted to be engaged .by one or the other of a pair of driving lugs 100 projecting laterally from the clutch disk 88. The clutch ring 86 is acted upon by a coiled spring 102, one end of which is secured to the lug 98 and the opposite end to the pulley 78. The tension of the spring 102 tends to'tilt the clutch ring 86 about its pivot stud 96 and to maintain it in the position in which it appears in F 14, the tilting movement of the clutch ring under the influence of the spring being limited'by a stop 104 which projects from the inner edge or the other of the driving lugs 100 on the clutch disk 88, the clutch ring is tilted against the action of the spring 102 until a stop 106, projecting from the inner edge of the ring, at a point diametrically opposite the stop 104, is brought into engagement with the hub of the pulley 78. With the above described construction, the shock in cident to the engagement of the driving lug 100 with the lug 98 is absorbed by the spring 102, and. the rotation of the cam shaft 70 is initiated withoutundue vibration. The noise resulting from the contact of the driving lug 100 with the lug 98 may be reduced or eliminated by means of bumpers 108 of leather or other suitable material which may be secured to the operative faces of the drivings lugs 100.

During normal operating conditions, the clutch members 86 and 88 are maintained in operative engagement, the cam shaft 70 is continuously rotated and the turret 24: is intermittently rotated by means of the feed pawl 86 and the pawl-carrier 38 the latter being, in turn, actuated by mechanism controlled by the cam 64. During each period of rest of the turret, the operator inserts a single lift in each of the pockets at the receiving stations 28 and 30. If for any rea son the operator should fail to insert a lift in either of the pockets at the receiving stations, he may interrupt the normal operation of the machine by disengaging the clutch members 86 and 88. 1

To this end, the clutch disk 88 is adapted to be shifted longitudinally of the driving shaft 80 by means of a crank 112 (Figs. 1 and 2) that is secured to the rear extremity of a horizontal rock shaft 11 and carries a stud 117 which projects into an annular groove 119 in a hub 121 formed upon the clutch disk 88. The rock shaft 114 extends forwardly from the crank 112 and is jour- 'naled in bearing brackets 116 on the base 50. At the forward end of the rock shaft 11% is secured a foot treadle 118 which extends to a position conveniently accessible to the operator. A coiled spring 120 is secured at its lower end to the treadle 118 and at its upper end to the forwardly projecting portion of the head 54;, and tends to maintain the treadle in its raised or inoperative position and to hold the clutch disk 88 in operative relation to the clutch mcinber 86. By depressing the treadle 118, the

ceiving stations 28 and 30, the treadle 118 may be released and the spring 120 will then raise the treadle and restore the clutch 1nemhers 86 and 88 into operative relation.

As best shown in Fig. 13, the rotary carrier or turret 24 comprises five disks 124, 126, 128, and 132, these disks being superposed in co-axial relation and disposed in a. horizontal plane with the lowermost disk slightly overlapping the inner edge of the annular feed table 22. lhe several carrier disks are all rigidly but adjust-ably secured together and are mounted to rotate as a unit upon the upper portion of a vertical post 134 which extends through central apertures in the carrier disk. As shown in Fig. 2 the post 184 is rigidly secured at its lower end in the forwardly extending portion of the head 54 and is screw threaded at its upper end to receive a nut 12-36 which engages the uppermost disk to prevent upward displacement thereof. Each lift-receiving pocket or recess 26 is defined by the outer ex tremities of a pair of lugs and 142 (Figs. 1 and 13) and the opposed extremities of a pair of levers 144 and 146. The lugs 140, of which there are five in number, one for each of the lift pockets 26, project radially from the periphery of the upper carrier disk 124, while the lugs 142, also five in number, project radially from the carrier disk 126 and are offset with respect to the lugs 140, as shown in Fig. 1. There are also five pairs of levers 144 and 146. Each pair of levers 144 and 146 is carried by a pair of arms 148 which project radially from the lower disk 132 and carry at their outer extremities vertical studs 150 upon which the levers are fulcrumed. The outer ends of the levers 144 and 146 are formed with vertically disposed semicylindrical portions 152 (Fig. 1) which, together with depending portions 154 upon the lugs 140 and 142, provide a set of liftengaging and alining faces which define the lift pockets 26. The opposite ends of the levers 144 and 146 are provided with rounded extremities 155 which are received in similarly shaped peripheral notches 156 in the carrier dis rs 128 and 130, respectively. As shown, the semi-cylindrical extremities 152 of the levers 144 and 146 are adapted to engage the lateral and breast edges of a lift adjacent the two breast corners thereof, while the depending portions 154 of the lugs 140 and 142 are adapted to engage the curved edge of a lift at points somewhat removed from the rear extremity thereof. By

means of the parts just described, the lifts When the lifts have been deposited in the pockets 26 are maintained in definite positions therein and a second lift placed in said pockets will be alined with the first lift. During the step movements of the carrier 24, the lower edges of the lift engaging portions 152 and 154 wipe across the feed table 22 and feed the lifts in a circular path.

To vary the size of the lift pockets 26 to accommodate lifts of different sizes or styles, the two upper carrier disks 124 and 126 may be adjusted radially with relation to each other to move the opposed memliiers of each pair of lift engaging lugs 140 and 142 toward or from the opposed member simultaneously. To this end, the upper carrier disk 124 is provided with a slot 156 (Fig. 1) which is inclined relatively to a radial line extending therethrough and the disk 126 is provided with slot which is inclined an equal number of degrees in the opposite direction and extends diagonally beneath the slot 158. The slots 158 and 160 are provided with slide blocks 1'62 severally -.ipertured to receive the shank of a belt 1434, having an elongated rectangular head 166 (Fig. 13) at its lower extremity which is arranged to slide longitudinally in a T-shaped groove 168 in the upper side of the lower disk 132. ihe upper entremity of the belt 164 is screw-threaded to receive a nut 170 which bears against the-upper slide block 162 and retains it within the slot 158. The downward displacen'ient of the lowermost slide block 162 is prevented by means of a collar 172 which surrounds the bolt 164- beneath said slide block, which rests upon the upper face of the lower carrier disk 132 at opposite sides of the groove 1'68. Circular apertures 174 are provided in the carrier disks 128 and 130 to receive the collar 17 2 and these apertures are of sufiicient diameter to permit free inward or outward adjustment of the bolt 164 in the groove 168 when the nut 170 is loosened. 13y thus adjusting the bolt 164 inwardly or outwardly in the groove 168, the blocks 162 are caused to siide obliquely in their respective slots 158 and 160 and the resulting cam action between the edges of said blocks and the side walls of the slots causes the carrier ' disks 124 and 126 to turn in opposite directions upon the post 134, thus varying the distance between the opposed members of each pair of lugs 140 and 142.

The levers 144 and 146 at each of the lift pockets 26 are adjusted about their fulcrnms 150 to vary the relation of their opposed extremities 152 and thus adapted to accommodate lifts of different sizes or styles. To this end, the carrier disks 128 and 130 are provided with slots 176 and 178 which correspond to theslots 158 and 160 in the carrier disks 124 and 126 and which are similarly inclined in opposite directions and are arranged so that one extends diagonally beneath the other. These slots 176 and 178 are provided with slide blocks 180 through which extends a -vertical bolt 182 having an enlarged rectangular head 184 at its lower extremity which is formed to slide longitudinally in a T-shaped groove 186 (Fig. 13), in the upper side of the lower carrier disk l82, and disposed at an angle to the corresponding groove 168 already described. The upper end of the bolt 182 is provided with a nut 188 and a collar 190 is interposed between the nut 188 and the upperslide block 180 to prevent upward displacement of the latter. The lower slide block 180 rests upon the upper face of the lower carrier disk 132 atopposite sides of the groove 186. The two upper carrier disks 124 and 126 are provided with circular apertures 192 into which thecollar 190 extends, this construction permitting the nut 188. to be located above the upper carrier disk where it mayv be conveniently manipulated. By loosening the nut 188, the bolt 182 .may be readily shifted either inwardly or outwardly in the groove 186, thus shifting the slide blocks 180 in their respective oblique slots 176 and 178 and varying the relative radial positions of, the carrier disks 128 and 130 in the same manner as already described in connection with the carrier disks 124 and 126. After the necessary adjustment-s have been made tovary the size of the lift pockets 26 inv accordance with the size of the lifts to be operated upon, and

the nuts 170 and 188 have been tightened, the five carrier disks are rigidly secured together and all rotate in unison as the carrier is intermittently actuated. V

During the intervals between the successive step movements of the turret or carrier 24, the latter is locked against rotationto maintain the several lift-receiving pockets 26 stationary in the proper positions relatively to the receiving stations 28 and 30, the pasting station 32 and the discharge station 84. The locking of the turret is effected by means of a stop pin 194 (Figs. 2, 3, 4 and 5) and a holding pawl 196 (Figs. 3 and which engage opposite sides ofone offive lugs 198, which are'equally spaced apart upon the under side of the lower turret disk 132 adjacent the marginal portion thereof. The stop pin 194 is mounted for vertical sliding movement in a' guide way 200 formed on the bracket 58and is cam actuated, as will be hereinafter de scribed. The holding pawl 196 is bifurcated at one end to straddle an ear 202 rising wardly by means of an expansion spring 206 (Fig, 3.5) the lower end of which is re Wired L na in t e brac e 58, Wh e the upper end thereof is received in a socket venient reach of the operator, the bin containing the lifts which are to be placed in the pocket at the station 28 being disposed at theleft of the operator, while the bin containing the lifts to be placed in the pocket at the station is located at the right of the operator. Thus the operator may use both handsto insert the lifts simultaneously at the two stations 28 and 30, the

lift being inserted at the station 30 with the right hand and the lift at the station 28 withthe left hand. At the expiration of the predetermined period of rest of the turret 24, if the two new lifts have been properly placed in the machine, the operator does not depress the stopping treadle 118 and consequently the machine is allowed to continue its normal operation. The turret is immediately unlocked by the retraction of the stop pin 194 and a step movement is imparted to the turret.

The stop pin 194 is actuated by means of a lever 210 (Figs. 2 and 3) which is fulcrumed upon a horizontal rod 212, supported at its opposite ends in the head 54. The forward end of the lever 210 is forked to receive a small roller 214 which is mounted upon the adjacent side of the stop pin 194 near the lower extremity thereof. At its rear extremity the lever 210 is pivotally connected with the lower end of a link 216,

the upper end of which is connected to the rearwardlyextending arm of a hell crank lever 218. The lever 218 is fulcrumed upon a .rod 220 which is secured at its opposite ends in the brackets 72. The depending arm of the-bell crank lever 218 carries a cam roll 222 which rides uponthe periphery of the cam 68. A short coiled spring 224 which is secured at one end to the forward portion of the lever 210and at the other end to the under side of the bracket 58, tends to holdthe stop pin 194 in its raised or operative position and to hold the cam roll 222 against the cam 68. The cam 68 is designed to effect the retraction of the stop pin 194 just prior to the beginning of each step movement of the turret 24 and to raise the stop pin into operative position in time to limit the extent of said movement by engagement with one of the lugs 19,8,

two fifths of a revolution.

V The step movements of'the turret or carrier 24 are produced by means of the feed pawl 86 which operates just after the retraction of the stop pin 194. As shown in Fig. 3, the feed pawl 36 is pivoted upon a vertical stud 228 on the pawl carrier disk 38 and is adapted to engage with one of the live lugs 198 on Itheund'er side of the lower turret disk 132. The feed pawl carrier disk 38 is rotatably mounted upon the post 184 Figs. S -and 4) beneath the turret and rests upon a boss 230 rising from the bracket 58. The feed pawl 36 is normally held in operative position, as shown in Fig. 3, by means of a coiled spring 232, one end of which is secured to the rearwardly extending tall 234 on the feed pawl, while its opposite end issecured toa pin rising from the feed pawl carrier disk 38. A stop pin 236 on the feed pawl carrier disk 38 limits the movement of the feed pawl under the influence of the spring and thus determines the operative position of the pawl 86. v

The feed pawl carrier disk 38 is oscillated by a horizontal rack bar 238, the teeth of which engage teeth 240 formed on the periphery of the pawl carrier disk 38. The rack bar 238 is mounted to slide in a guideway formed in the bracket 58. At is rear extremity, therack bar 238 is connected by means of a linlr 242 with the lower extremity of a lever 244 which is fulcrumed at its upper end upon the rod 220. V The lever 244 is provided with an extension 245, the for ward portion 246 of which is offset into the vertical plane of a cam lever 248 which is fulcruined upon the rod 220. 'The c'am lever 248 carries at its lower extremity a cam roll 250 which traverses a groove in the side of the cam 64. As shown in Fig. '2, the cam lever 248 and the forward extension 246 of the lever 244 are connected by a spring 252, the tension of which tendsto hold the lever 244 in the position shown in Fig. 2 in which -the rack bar 238 is at the forward limit of its movement and the feed pawl 36 isi-n readiness to advance the turret This position of the lever 244 is determined by an engagement with the lever of the offset end of a stop arm 254 which isi formed integrally with the cam lever 248. With variations in the number o-flift pockets on a turret of the same diameter the effective throw of the lever 248 will vary and the spring 252 functions *to" permit this variation without adjustment.

The cam 64 and the above described mechanism associated therewith is constructed and arranged to retract therack bar 238 to effect the oscillationof the turret 24 through This movement of the turret causes two of the lugs 198 to pass above the holding pawl 196. Just prior to the passage of the second lug 198 above the holding pawl. 196, the stop pin 194 is raised into operative position in the path of said lug. When said lugengages the stop pin 194, further'movement of the turret 24 is arrested and the holding pawl 196 is forced upwardly into'operati've engagement with the other side of the lug 198, so that the turret 24 is positively locked against further rotation in either direction. This locking of the turret occurs just before the cam has imparted its full rearward movement to the lever 244 and thereafter the spring c: pan'ds, thus permitting the completion of the movement of the cam lever 248. This construction insures that the turret 24 will be brought to rest with its pockets accurately positioned at the several stations.

During the operation of the machine, whenever the turret 24 comes to rest between successive step movements thereof, the lift pocket positioned at the station 28 will be empty, the heel-section formerly occupying this pocket having been discharged by the plunger 42 at the preceding cycle of operations. The lift pocket which is positioned at the station 30, however, will contain a single lift, to the upper face of which a coating of paste was applied when said pocket was last positioned at the pasting station 82, i. e., two steps of the turret prior'to the last step. After each step movement of the turret, as already described, the operator places a single lift in each of the pockets at the receiving stations 28 and 30, the lift placed in the pocket at the station 30 being superposed upon the freshly pasted lift at that time occupying said pocket. Consequently at the next step movement of the turret 24, the heel-section comprising the two lifts which have been assembled in the pocket at the station 30 will be carried beyond the pasting station so that the upper lift will not be coaled with paste and said heel-section will be brought to rest beneath the plunger 42 at the discharge station '34 in readiness to be discharged into the press 46. During this step movement of the turret, the single lift in the pocket at the station 28 will be positioned at the pasting station 32 in readiness to be operated upon by the pasting device 40 which applies a coating of paste to the upper face of the lift.

The pasting device 40 comprises, in general, a paste pot (Figs. 1, 5, 6 and T) an o cillating paste pad 260, w'liich, during each step movement of the turret, is moved into position above the paste pot \vh'erc it receives a coating of paste upon its lower face and I which then moves into position above the lift pocket at the pasting station where, after the turret comes to rest, it applies the paste to the upper face of the lift in said pocket; a horizontal paste plate 262 adapted to be lowered into the paste in the paste pot 258, and thereafter to be raised into ci'n'lhict with the paste pad 260 to transfer a limited projecting ears on opposite sides. of, the paste pot and are threaded into said bracket. The paste pot is open atthe top to permit the entrance oithe paste pad 260.

The paste pad 260' which is constructed of suitable absorbent material, is carried by a block 270 which is secured to the lower side of a flat horizontally disposed supporting head 2'72. The pad 260 and the block 272 are of a size and shape corresponding-to that of the lifts or blanks being operated upon to permit the pad to enter the pockets 26. The paste pad 260 is swung back and forth between a paste-applying position above the I lift pocket at lthe pasting station and a paste-receiving position above the paste pot 258. Inorder that the paste pad shall be properly positioned toreceive the paste from the paste plate262 and to apply it to the heel lifts, provision is made for maintaining the pad at all times in a horizontal plane. To this end, as shown in Figs. 5 and 7 the paste pad supporting head 27 2 is carried at the lower end of a stem 274 which is pivotally connected by means of studs 276 and 278 to the outer ends of a pair of arms 280 and 282, which are rigidly secured to a pair of horizontal rock shafts 284; and 286, respectively. The rock shafts 284 and 286 are journaled in suitable bearings formed in oneof two upright frame members 288 which rise from opposite sides of the paste pot 258. At the opposite ends of the rock shaft 284 from the arm 280 is secured a pinion 290, and to the opposite end of the rock shaft 286 from the arm 282 is secured a pinion 292. Meshing with the pinions 290 and 292 are idler pinions 29-1 and 296, respectively, and meshing with both of the idler pinion is a rack 298 whichextends vertically through an opening 299' (Fig.3) in the bracket 58 and is mounted for sliding movement in a guideway 300 at the outer side of the adjacent frame member 288. Therack 298 is adapted to bereciprocated to rotate the arms 280 and 282 in unison to swing the paste pad 260 back and forth between the paste-applying and paste receiving positions. By virtue of the parallel relation of the arms 280 and 282, the

paste pad is maintained at all times in a horizontal plane. The construction of the means for actuating the paste pad 1s such that as the pad is moved from one extreme position tooanother, it is lifted clear of the adjacent side wall of the paste pot 258.

The 'ack 2.981s raised by means of a veroted upon a stud 810 projecting from the side of the adjacent bracket 288.

The actuator segment 30% is guided for vertical movement by means of three guide rods 312 (Figs. 2, 3 and depending upon the bracket The actuator segment 304; is raised and lowered by means of a pair of bell crank levers Blwhich are fulcrumed at opposite sides of the forwardly projecting portion of the head 54: and a third bell crank lever 316 which is fulcrumed upon the rod 212. The forwardly extending arm of each pair of bell crank levers 314 engages between upper and lower lugs 318 projecting inwardly from opposite sides of the actuator ring, while the forwardly projecting arm of the bell crank lever 316 engages between upper and lower rearwardly projecting lugs upon the central portion of the actuator segment (Fig. The downwardly extending arms of the three bell crank levers are conends of three arms secured to a. horizontal rock shaft 324- which is journaled in bearings in the rear portion of the head 54-. The rock shaft 32% is actuated by means comprising an 211111.326 (Figs. 2 and se cured to the rock shafha link 328,. the lower end of which is pivotally connected with the arm 326, and a bell crank cam lever 330 having a rearwardly extending arm pivotally connected to the upper end of the link 328. The cam lever 330 is fulcrumed upon the rod 220 and is provided. with a downwardly extending arm carrying a camroll which travels in a groove in the side of the cam 62. The cam 62 is designed to effect the raising and lowering of the actuator segment 30-1 to actuate the paste pad 260 so that a coating of paste will be applied to the blank which is positioned at the pasting station 32 during the period of rest of the turret 24 at each cycle of operations of the machine.

By means of the above described construe tion and arrangement of thc'bracket 58 and the actuator segment 30%, the required number of pasting devices may be readily attached to the machine and actuated for lifts, it will be necessary i lowerend of a vertical rod inbuilding a heel-section composed of four to provide the machine with three pasting devices. These pasting devices may be located upon the bracket 58 in. the proper. positions relatively totheseven or nine pockets 26, as the case may be, when the latter occupy their positions of rest. Suitable openings corresponding to the opening 299 will be provided in the bracket 58 to permit the passage there- .through of additional racks similar to the rack 29.8 for actuating the paste pads of the several pasting devices. In whatever radial position said racks may be located, their lower extremities will rest upon the actuator segment 30% so that they will be raised thereby without requiring any change whatever in the segment or its actuating means.

When the paste pad 260 occupies the position in which it appears in Fig. 6, a coat ing of paste is supplied thereto by means of the paste plate-262. After each engagement of the paste pad 260 with the paste plate 262, the paste plate is lowered into the paste in the paste pot 258 and then raised again into position for engagement wi h the paste padafter the pad has transferred the paste to the lift at the pasting station. To this end, the paste plate 262 is carried at the 336 which is mounted for vertical sliding movement in guideways 338 formed at the inner side of one of the frame members 288. The rod 336 is acted upon by a spring 340 which is coiled about the rod and is interposed between the upper guideway 338 and av collar 3&2 which 1s secured to therod 336. The force of the spring 340 tends to lower the paste plate 262 into the paste in the paste pot 258. The paste plate is raised into position for engagement with the paste pad 260 by means comprising an arm 34% which is secured to a horizontal rock shaft 346 that is journaled in hearings in the frame members 288, the arm 344 being provided with a laterally projecting pin 248 which enters a transverse notch 350 in the lower portion of the rod The rock shaft 346 is actuated to oscillate the arm 3% by means of a cam lever 352 which is secured at its lower end to the rock shaft 346 and carries at its upper end a cam roll 354 which rides upon the periphery of a cam disk 356 that is secured to the shaft 286. The cam 356 is so designed that when the paste pad 260 is positioned, as shown in Fig. 5, in readiness to apply paste to a lift at the pasting station, the spring 340 will maintain the paste plate 262 in its lowermost position in which it is submerged in the paste potbut as the paste pad approaches the paste receiving position in which it appears in Fig. 6, the paste plate 262 is raised into positionto be engaged by the pad and apply a coating of'paste thereto.

In order that the lifts at the pasting stapaste receiving position,

the reservoir is tion may be prevented from adhering to the paste pad 260 and thus being raised from the pockets 26, as the pad swings toward its means is provided for stripping the lifts from the paste pad. Tothis end, a pair of stripper pins 360 are mounted to slide vertically through guideways which extend through the paste pad 260, its supporting block 270, and the carrier plate 272. lhe stripper pins .360 depend from opposite ends Ofzit horizontal supporting ar 362 which is carried at the lower extremity of a vertical plunger 364, the latter being mounted for sliding movement in a bore 366 provided in ;a lateral enlargement in the stem 274. The plunger 364i is urged downwardly by a coiled spring 368 which is confined within the bore 366, its lower end engaging the-plunger 36 i and its upper end bearing against a screw 370 which isthreaded intorthe upper :end of the bore 366 and may be turned to vary the compression of the spring. Normally the supporting bar 362 is maintainedin contact with the upper facelof the paste pad support plate 27 2 by the force ofv the spring 368. The length of the stripper-pins 360 is such that when the supporting bar 362 is thus positioned, the lower extremities of the stripper pins project below the lower face of the paste pad, as shown in Figs. 6 and 7. \Vhen the paste. pad is brought into. engagement with a lift in the pocket at the pasting station, the spring 368 yields under pressure on the stripper pins so that the paste pad may come into contact with the lift, as shown in Fig. 5. Asthe paste pad is raised after applying a coating of paste to the lift, the stripper pins are moved downwardly relatively to the pad by expansion of the spring 368 and the pasted lift is thus stripped from the paste pad. When the paste pad is moved into engagement with the paste plate 262, the lower ends of the stripper pins 360 project through openings 372 (Figs. 1 and 7) in the paste plate.

The paste reservoir 26% comprises a cylindrical. tank which vertically disposed inn 1, bolted to the outer side of one. of the brackets 72, as shown in Fig.1. The closed upper end of the reservoir 262l'is provided with a cover 376 which may-be removed for the purpose of filling the reservoir. A plurality of cocks 378 at the bottom of the reservoir are provided with manually operable valves for controlling the outflow of the paste. By means of the several cocks 378 adapted to be connected with two or more pastepots for the purpose of adapting the machine'to produce heel sections composed of three or more layers or lifts. In the illustrated machine which is provided .withbut a single ipasting device, one only of the cocks 378 is utilized, the others being closed as indicated inFig. i

As shown in the drawings, paste is conveyed to the paste pot 258 through a conduit comprising a flexible tube 380, and a short vertical pipe 382 (Fig. 7). The upper end of thetube 380 is connected with the cock 378 which is shown in open position in Fig. 8. The pipe 382 is rigidly secured to they outer side of one of the frame members 288, and the upper end of said pipe is connected with the lower extremity of the tube 380. The lower portion of the pipe 382 extends downwardly a short distance into a laterally extending portion 384 of the paste pot-258, as shown in Figs. 1 and 7.

In'order that the flow of the paste from the reservoir to the paste pot 258 may be controlled by atmospheric pressure, all joints in the. reservoir are made air tight and the cover 37 6 fits tightly so that air is prevented from entering the reservoir except through the cock which is connected with the paste pot. As soon as the supply of paste in the paste pot risesabove the lower end of the pipe 382, the paste seals the opening at the lower end of the pipe against the entrance of air and no paste will flow from the reservoir into the pastepot. \Vhen the paste in the paste pot 258 has been so depleted that the level of the paste falls below the end of the pipe, paste will flow from the reservoir into the paste pot until the lower end of said pipe is again sealed. In this way, a substantially uniform quantity of paste is maintained in the paste pot.

After a lift has received a coating of paste at the pasting station 82, the next step movement of the turret carries the lift to an idle station between the receiving station 28 and the discharge station 34;the second step movement of the turret brings said lift to the receiving station 30 where a new lift is superposed by the operator upon the pasted lift; while at the third succeeding step movement of the turret the two superposed lifts are brought to the discharge station 34 where they'are located beneath the plunge-r 42 and above the tube press 46. The plunger operates to force the lifts downwardly through the opening 44 in the table 22and into the press 46.

As shown in Fig. 3,.the opening 44 in the table 22 is formed within a plate or die 388 consisting of two sections normally arranged in butting 'end-to-end relation, as shown in Fig. 3. The sections of the die 388 fit into a shallow recess 392 in the upper face of the table with their upper faces flush with the upper face of the table. One of the die sections is rigidly secured to the table,

while the other die section is secured to the and arrangement of the slots 396 and of the re es e pa t esef the t e :2 5 uch a t permit edgewise movement of one section toward and from the other. The ad uStable section is yieldmgly pressed toward the fixed section by means hereinafter to be described,

this arrangement facilitating the downward passage of the lifts therethrough.

The plunger 42, by means of which the completed heel sections are removed from the pockets 26 as the latter are positioned at the discharge station 84 and are loaded into the press 46, is mounted for vertical reciprocation in a guideway formed in a brack'et 400 (Fig. 2) which rises from the rear of the bracket 58. The plunger 42 is reciprocated by means of a cam lever 402 which is pivotally mounted upon the rod 220, the forwardly extending arm of said lever having a head, shaped to seat within a vertical slot near the upper extremity of the plunger 42. (See Figs. 1 and 2). The

upper and lower walls of the slot form bearings for the head of the lever 402 which is rounded,as shown, readily to rock in said slot. The cam lever 402 is provided with a downwardly extending arm which carries a cam roll 408 that traverses a groove in the side of the cam 66. The cam 66 is designed to efiect a reciprocation of the plunger 42 at each cycle of operations of the machine so that an assembled heel section will be discharged from the turret and loaded into the press 46 after each step movement of the turret. The heel press 46 consists of a tubelike structure comprising an elongated vertical breast member 412 (Figs. 9 and 10) stationarily supported and adapted to engage the breast edges of the heel sections, and six elongated vertical side members, three of which, indicated at 414, are adapted to engage the curved edges at one side of the heel sections, and the other three of which, indicated at 416, are adapted to engage the curved edges at the opposite side of the heel sections. The side members 414, 416 are movable relatively to each other and are spring pressed inwardly to frictionally resist the passage through the press of the heel sections. By reason of this frictional resistance, the operation of the loading plunger 42 results in transmitting a succession of pressure impulses to the column of heel sections in the press 46 so that said sections are firmly pressed together and are held under continuous pressure. during the setting of the paste. Means is also provided, as will hereinafter appear, for adjusting the side members 414, 416 inwardly or outwardly to vary the cross sectional area of the press to accommodate heel sections of different sizes.

All of the side members of the press are carried by a frame which is indicated generally at 418 in Fig. 17. The supporting frame 141:8 comp-rises upper and lower hori' zontal arias 429 whieh are curved pan tially encircle the press and a vertical web 422 connecting one extremity of the upper arm 420 with the corresponding extremity of the lower arm 420. The supporting frame 418 is rigidly but removably secured to a bracket 424, best shown in Fig. 18, supported on the pedestal 52 and having two outwardly extending arms 426 for support ing the frame. 418.

Although the side members of the press are adjustable transversely to vary the size of the press; the'range of adjustment of these members is necessarily limited and in order that heel" sections larger or smaller than those which the press may be adjusted to accommodate may be operated upon by the. machine, it is contemplated the entire press 46 shall be removable as a unit in order that other presses may be interchange ably received in the machine, these presses being adapted for adjustment to accommodate either larger or smaller heel sections than those which may be accommodated by the press whichhas been removed.

To this end the press supporting frame 418 is removably secured to the bracket 424 in the following manner. As shown in Fig. 17, the presssupporting frame 418 is provided witha pair of ledges 428 which severally project laterally beyond the web- 422 at the opposite side thereof from the curved portions o't the arms 420 and these ledges are adapted to rest upon the arms 426 of the bracket 424. The frame 418 is secured to the bracket 424'by means oftaper pins 430 (Fig. 9), two or which are provided in the upper ledge 428 and one in the lower ledge 428. The taper pins 430 are seated in taper openings in the ledges andare arranged with their lower extremities extending beyond said ledges and projecting. into tapered holes in the arms 426 of the bracket To facilitate the attachment of the press to the machine orits removal therefrom, a stem rises from the end ot each taper pin, 430 and extends through an aperture in a bracket 43dwhich is secured to the cor- 'rcsponding arm 420 o't the frame, 418. Each: taper pin 430 is normally held in the position in which they appear in Fig. 9 by means of a spring whichis coiled aroundthe stem. 434 between the upper end of the pin 4'30. and a shoulder formed on the bracket 436. Each stem 434 is provided with a knurled head 440 by means of which the taper pins 430'n1ay be raised to lift them out of the openings 482 in thebracket 424 to permit the removal of the press from the machine. To latch the taper pins 430 in their released positions,.a small pin 442 projectslaterally from K the' upper end of the taper pin and when the taper pin has been raised clear ofthehole 43-2, itmaybe turned y me n of its knur ed head 440 untilthfi pin 442 enters a notch 444 in the bracket 436. The taper pin will then be held in its released position until the knurled head 440 is turned in the opposite direction.

The side members 416 of the press comprise elongated flat bars each of which is rigidly secured to the inner ends of a pair of upper and lower supporting arms 448 and so arranged that the inwardly facing longitudinal edges of the bars are adapted to engage the lateral edges of the heel-sections. The three pairs of supporting arms 448 are loosely mounted upon three vertical rods 450 (Figs. 9, 10 and 17) which are rigidly secured to the upper and lower arms 420 ot the bracket 418. The rods extend between said arms 420 and their upper ends project above the upper arm 420, as shown in Fig. 17. The upper side member supporting arms 448 rest upon the upper press frame arm 420., while the lower arms 448 rest upon the lower press frame arm 420. The side members 414 are identical in con struction to the side members 416 and each of said side members is rigidly secured to the inner ends out a pair of upper and lower supporting arms 452. There are three pairs of arms 452 and each pair is loosely mounted upon one of the rods 450 above the arms 448 (see Fig. 11). The uppermost of each pair of arms 452 rests upon aslotted cam segn'iont 454 (Figs. 11 and 12) which is interposed between the hubs of said arms and the hubs of the uppermost of the arms 44S and whichis utilized for the purpose of adjusting said arms inwardly or outwardly, as will be hereinafter explained. The lowermost of each pair of arms 452 rests upon a slotted cam segment. 456 (Fig. 9) which is identical in construction to the cam segment 454 and is interposed between the hubs of said arms and the hubs ot the lowermost of each pair of arms 448. The segment plate 456 is actuated concurrently with the cam segment 454 to secure the inward or outward adjustment of the side members of the press.

The breast member-412 consists of a T-bar arranged with its cross web facing toward the interior of the press toward the side members 414 and 41 6 in a. position to engage the breast edges of theheel sections. and is provided with upper and lower laterally projecting bosses 45S (Figs; 10 and 19). To these bosses are pivotally connected the substantially vertical arms of a pair of bellcrank levers 460. The function of these bell-crank levers will presently be explained and they are referred to at this time because the breast member 412 is supported on the frame 418 by studs 462 on which the bellcranks are fulcrumed.

All ot-the six side members 414 and 416 of the press are forced inwardly by means of a plurality of coiled springs 464 which liO are wrapped around the side members intermediate the upper and lower ends of the press. As shown in Fig. 10, the opposite ends of the spring 464 are secured to the breast member 412. The tension of the springs 464 forces the side members of the press inwardly and normally holds them with their upper extremities in engagement with a depending flange 466 on the under side of the plate or die 388. As shown in Fig. 9, the upper ends of the side members are beveled slightly to conform to a cone sponding bevel of the outer face of the flange 466. The flange 466 limits the inward movement of the several side members of the press, and thus determines the size of the press in accordance with the size of the blanks which areto be operated upon. If it is desired to operate upon blanks of a different-size, the die 388 is removed from the ,niachine and replaced by another die having an opening corresponding in size to the size of the blanks to be operated upon.

To prevent the collapse of the press upon the removal of the die 388 and to obviate the resulting difficulty in adjusting a new die in the machine with its flange 466 properly positioned to limit the inward movements of the side members 414 and 416 of the press, means is provided for opening up the press bymoving the side members outwardly and for maintaining them temporarily in their opened position. The means for moving the side members outwardly comprises the cam segments 454 and 456 (Fig. 9) already referred to, manually operated actuating mechanism interconnecting said segments, and a latch 470 (Figs. 2, 9 and 16) for operating with said mechanism. As de scribed, the cam segments 454 and 456 rest upon the hubs of the adjacent arms 448 which support the side members 416 of the press. As shown in Fig. 12, each of the cam segments is constructed with an elongated ancuate slot 472 through which the vertical rods 450 extend, the slot 472 being of suiticient length to permit longitudinal edgewise movement of the cam segment in an arcuate path determined by the contour of the slot. Each. cam segment is provided with three actuating lugs 474 which project inwardly from the inner edge of the segment and with three actuating lugs 476 severally projecting from the other edge of the segment. The lugs 474 are so arranged that when the cam segment is shifted in the direction of. the arrow in Fig. 12, the lugs are brought into engagement with three studs 47 8 which depend from laterally ofii-set portions of the arms 452 and operate to swing the arms in a counter-clockwise direction to move outwardly the side members 414 of the press. The actuating lugs 476 are severally provided with. inclined cam faces 486. When the cam is hift d a a o described, the cam faces 480 engage with three studs 482 severally rising from three arms 484 which are formed integrally with the arms 448 and are so disposed in rela-s tion thereto as to constitute bell crank levers, as clearly shown in Fig. 10.

The cam segments 454 and 456 are shifted for the purpose of opening or closing the side members of the press by means of a pair of hell crank levers 486 (Figs. 9 and 16) which are fulcrumed upon studs 488 carried by the arms 420 of the press supporting frame 418. The upwardly extending arms of the bell crank levers 486 are severally provided with rolls 490 whicn project into notches 492 (Fig. 12) severally formed in the cam segments between one of the lugs 476 and a lug 494 which projects from the the press are temporarily maintained in their opened position by means of the latch 470, the lower extremity of which is pivoted to the upper arm 420 of the press supporting frame 418. To this end the latch 470 is normally held by gravity in the position in which it is indicated in Fig. 1.6 with one edge face of the latch in engagement with an extension 500 of the horizontal arm of the upper bell-crank lever handle 498 has been lifted to its uppermost position, the extension 500 is raised above a shoulder 502 on the latch 4T0, whereupon said shoulder swings into position beneath said extension, thereby preventing the return of the bell crank levers 486 to their normal positions and consequently latching in their open position the side members of the press. The latch 470 is provided with an upward extension 504, by means of which it may be manually tripped. to permit the springs-464 to move said side members of the press inwardly until their movement is arrested by the flange 466 upon the die 388.

In order that the breast member 412 of the press may be moved outwardly concurrently with the side members 414 and 416, the horizontal arms of the'bell-crank levers 460 are connected by means of a vertical link 506 (Figs. 2 and 19) and the lowermost of said bell-crank levers is provided with a third arm 508 which is connected by a link 510 with the downwardly extending arm of a bell-crank lever 512 (see also Fig. 16). The bell-crank 512 is pivotally mounted upon the lower arm 420 of the presspSuPporting frame 486. I l-Vhen the iii-i) 418, and is provided with a forwardly extending arm having an open ended slot therein through which extends a pin 514 carried by a bifurcated extension at the lower extremity of the link 496. By means of this construction, when the handle 498 is lifted, the breast member 412 will be swung outwardly concurrently with the outward movements of the side members 414 and 416 due to the forward pull on the link 510. The latch 470 thus serves to hold all seven of said members in their opened or outermost positions. When the side members of the press have thus been swung outwardly and latched in their outermost positions, the die 388 may be removed and the new die of a different size substituted therefor. Thereafter, when the latch 470 is tripped, all of said members are moved inwardly concurrently through the agency of the springs 464 until their upper ends are brought into engagement with the flange 466 on the lower side of the die then in position. The press is thus adjusted in accordance vith the size of the heel sections which are to be built.

In removing the press from the machine, the handle'498 is first lifted to move the side members of the press outwardly until the latch 470 becomes operative to lock said members in their outermost positions against the force of the springs 464. The taper pins 430 are then lifted permitting the entire press to be readily detached as a unit from its supporting bracket 424. A new press may be readily placed in operative position in the machine after the side members of the press have been locked in'their outermost positions and the taper pins 480 have been lifted and held in their uppermost positions.

The heel-section pressing and delivering mechanism which has been described in detail is not claimed herein except in combination with the heel-section assembling mechanism, since this mechanism forms the subject-matter of a divisional application Ser. No. 46,001, filed July 25, 1925.

It has heretofore been explained how the lift receiving pockets 26 may be adjusted as to size by varying the relation of the levers 144 and 146 to the lugs 140 and 142 (see Figs; 1 and 1S). lVhile the adjusting mechaninsm described is accurate and will cause the levers and lugs to grip and hold'lifts dinked accurately to size, those skilled in the art of making heels will understand that at times the lifts will not be gripped because of'some imperfection, an inaccurate dinking, or careless sorting. Such lifts will be carried over the feed table 22 by the rotation of the carrier or turret 24, but in the machine illustrated in Figs. 1, 2 and 3 there is danger that such loosely held lifts will fall from the pocket into the die as it traverses the die opening 44' in passing from the pasting station 3210 the station at the left of the die openingi To overcome this difficulty it is proposed to temporarily close the die opening during the period of time that a pocket holding a single'p'asted lift is passing thereover, or, in

a machine for making heel-sections of three or more lifts during the times when incomplete heel-sections are caused to pass over the die opening. A mechanism having this function is illustrated in Figures 20 to 22.

The means employed to close the die opening is a horizontally arranged cover plate 520 adapted to slide in a way formed for its reception at the base of the bracket 400 which carries the guide for the ejecting plunger 42. To this end the fram 20, adj acent the rear edge of the feed table, is provided with a channel member 522 (Fig. 22) on which is bolted a cap piece 524. The cap piece has a central portion 525 which depends in the channel and is of such proportions as to leave a space between its lower face and the channel member equal to the thickness of the plate 520'. The upper face of the cap piece is faced'and supports the usual bracket 400 which is shortened sufficiently to maintain the guide for the ejeoting plunger 42 in the same position as shown in Fig. 2. The bracket 7 2 which supports the cam shaft and bell-crank hanger rod 220 is unaltered, and in Fig. 20 the bellcrank 402 for operating the plunger 42 is shown but its operating cam is omitted. Both arms of the bell-crank 402 are embraced by the forked upper end 526' of a lever 528 pivoted at 527 on the depending arm of said bell-crank. The fork 526 is connected at its upper end by a cross pin 529 which carries a central roll 530 (Fig. 21). A spring 532 attached to said pin 529 and to a pin 534 on the depending arm functions to maintain the roll 530 in contact with the bell-crank. As the bell-crank 402 oscillates, the lever 528 is constrained to oscillate with it. The movement thus imparted to the lower end of the lever is transmitted to the slide plate 520 through a link 536 connecting the lever to the rear end of a central rib 538 extending longitudinally of the plate at its uppr side. The central part 525 of the cap piece 524 is provided with a slot 540 (Fig. 22) which receives the rib 538 and their engagement serves to guide the plate in its movement toward and from the die opening.

In operation, as the plunger 42 rises, to permit rotation of' the lift carrier 24, the bell-crank 402 acts to swing the lower part of the lever 528 to the left, in Fig. 20, thus advancing the cover plate 520. In Figs. 20 and 21 the plate 520 is shown as advanced part way to its final position when the die opening is closed. When the plunger 42 being advanced. On the withdrawal of the cover plate 2. lug 539 on the rib 538 stops the rearward movement by engaging a stop I 541 at the rear end of the slot 540. The con tinued downward movement of the plunger thereafter merely stretches the spring 532.

The control of the cover plate by the means for operating the plunger insures a proper time relation of the two movements and effectually provides for a retention of the partly completed heel-sections 1n the pockets of the carrier 26 as they pass over the die opening.

As the pasted heel-sections are successively loaded into the press by the. loading plunger 42, they are frictionally held between the several side and breast members of the press and their passage through the press is resisted thereby. As a result the heel-sections are continuously subjected to pressure during their advance through the press. The length of the press is such that when the heel-sections finally emerge from its lower end the paste has become set so that the component lifts or layers of the heel-sections are firmly secured together without the necessity of nailing.

By varying the number of lift pockets or recesses in the turret 24 and the number of lift receiving stations and pasting devices, and by varying the extent of the step movements of the turret, all as hereinbefore described, the present machine may be adapted to produce heel-sections composed of three or more lifts.

In each case where the number of pockets is one more than twice the number of lifts in the heel-section to be produced, and the distance traversed by a pocket at each step of the turret is always through the same number of spaces between pockets as there are lifts in said heel-section. This results in a complete heel-section being produced and ejected into the tube press after a number of turret steps, in each case, equal to one less than the number of pockets, and thereafter a complete heel-section is formed and ejected at each succeeding step so long as the receiving pockets are supplied with lifts. In order to prevent partially completed heelsections from being delivered to the tube press, the operator, in the five pocket form of the machine, will for the first three steps of the turret place a lift only in the pocket at the receiving station 28. After the third step of the turret the first lift inserted at 28 will be delivered to the pocket at the receiving station 30, the second lift will be delivered to the station at the left of the ejecting station 34, and the third lift will be at the pasting station 32. Lifts are nowfplaced in fourth turret step, By placing a lift in each pocket at stations 28 and 30 at each period of rest thereafter, a complete heelsection is forced into the tube press at each succeeding step of the turret. In each case the pocket which delivers directly to the tube press is not supplied with a lift until the turret has taken enoughsteps to cause lifts placed in the other pockets to be delivered thereto in sufficient number that the addition of one lift will complete the heelsection to be produced, i. e. not until the turret has been primed. While it is preferred to employ the specific construction and arrangement of parts herein illustrated and described it will be understood that such construction and arrangement is not essential except so far as defined in the appended claims, and may be variously changed or modified within the skill of the artisan without departing from. the spirit and true scope of the invention. What is claime-das new, is: p 1. A heel building machine for forming heel-sections of at least two lifts having, in combination, a frame providing a number of lift-receiving stations equal to the number of lifts in the heel-section and a discharge station; a conveyer provided with a number of lift-holders equal to one more than a multiple of the number of lifts in the heelsection to be formed, an equal number of said holders registering with said receiving and discharge stations when the conveyer is at rest; and means for periodically advancing the conveyer through the same number of spaces between the holders as there are lifts in the heel-section.
