HEEL PRESS.

Application filed March 23, 1917, Serial No. 156,824. Renewed July 10, 1922. Serial No. 573,919.

To all to 710m it may concern Be it known that I, Enas'rns E. XVINKLEY, a citizen of the United States, residing at Lynn, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Heel Presses; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to machines in which heel stock, such as heels or heel-piles, or parts thereof, newly built of layers or lifts cemented together, are held under pressure during the setting or drying of the cement.

One object of the invention is to produce a heel-press of which the parts are so arranged as to permit the convenient introduction and removal of the heel stock, while at the same time the machine occupies a minimum space and does not obstruct the light in the room in which it is used.

To the foregoing end the machine of the present invention is provided with a series of heel-clamps, which are supported for movement in a horizontal plane, and the clamps are provided with upper and lower substantially horizontal heel-engaging members or jaws, the parts being so arranged that the heel stock may be introduced to and removed from the clamps horizontally, by movement in the plane of rotation of the clamps.

Another object of the invention is to provide for the convenient adjustment-of the clamps according to the size of the heel stock to be operated upon. To this end the clamps are so constructed and mounted that they may all be adjusted simultaneously and in equal degree by a single operation.

Another object of the invention is to produce a heel-press of which the operation is controlled by, or in connection with. the act of manually introducing the heel stock. To this end the machine is provided with devices operating simultaneously, when the heel stock is so introduced, to initiate the cycle of operations of the machine, while the actuating-mechanism automatically ceases its operation upon the completion of such cycle.

Other objects of the invention. and the features of construction by which they are attained, are set forth in connection with the following description of the illustrated embodiment of the invention.

In the accompanying drawings Figure 1 1s a side-elevation of a heel-press embodying the present invention, with parts broken away to illustrate the construction more clearly;-Fig. 2 is a detail-view showing part of the mechanism for opening the heelclamps; Fig. 3 is a partial plan-view of the machine; Fig. 4 is a detail-view, in sideelevation, of the feed-table and parts immediately associated therewith; Fig. 5 is a plan-view, in section on the line 5-5 in Fig. 1; Fig. 6 is a detail-view, in elevation, of the clutch-mechanism through which the machine is actuated; Fig. 7 is a detail-view, partly in horizontal section, of part of the mechanism for rotating the clamp-carrier;

and Fig. 8 is a detail-view, in elevation, of

a part of the same mechanism.

The invention is illustrated as embodied in a heel-press in which an endless series of thirty-two heel-clamps are employed, arranged in a circle. Each clamp comprises upper and lower members .or jaws 10 and 12 respectively. The upper jaws 10 are supported by an annular member 14 constituting a part of the clamp-carrier. These jaws are mounted with provision for a pivotal or rocking movement to accommodate the clamps to such angularity as may exist between the upper and lower surfaces of the heels. For this purpose the member 14 is provided with concaved seats 16 for each jaw, while the jaw is provided with convex bosses 18 which rest in the seats. A lug 20 projects upwardly from the jaw between the bosses and through a slot in the seat, and is secured loosely in place by a cross-pin. The lug slides freely in the slot to permit a rocking movement of accommodation in the clamp-jaw.

The lower jaw 12 of each clamp is movable towards and from the upper jaw to clamp and unclamp the heel. For this purpose it is mounted on a stem 22, which slides vertically in openings in upper and lower annular members 24 and 26 constituting parts of the clamp-carrier. A spring 28, surrounding each stem, is seated, at its lower end, upon the carrier-member 26, while its upper end presses against the clamp-jaw and tends to raise the latter, and thus to subject the heel between the jaws to a constant pressure suflistationary vertical tube 4 I.

cient to force the layers of material closely together While the cement is drying. The carrier-members 24 and 26 are held rigidly in parallel relation by uprights 3O projecting from the member 26 and fixed, at their upperends, to the member 24.

In order that the clamps may be opened by a minimum movement of the lower jaws, in opposition to the springs 28, the upper jaws are made adjustable towards and from the lower jaws, in accordance with the size of the heels to be operated upon. T 0 permit this ad ustment to made simultaneously and equal for all of the upper jaws, it is accomplished by moving the carrier-member 14 vertically, while maintaining its parallel relation with the members 24 and 26. For

this purpose the member 14 is provided with afiseries of inwardly projecting lugs 32 v'vhich are perforated to receive a series of vertical rods 34. Each rod is screw-threaded and passes through a correspondingly threaded opening in the carrier-member 24, While the lug 32 rests upon a collar 36 fixed on the rod. At its upper extremity each rod is provided'with ahead 38 engaging the upper surface of the lug. In this manner the carrier-member 14 is supported firmly at a fixed, but adjustable, distance above the member 24, and this'distance may be ad accurately adjusted.

T he intermediate carrier-member 24 is provided with webbed spokes 42 which unite a central hub arranged to turn upon a This tube fixed, near its lower end, in a column 46 rising from the bed-plate 48 of the machine.

The hub of the carrier is supported upon a second hub 50 which turns about the tube 44 I charged. This intermittent movement is for a purpose to be described. To support the hub 50 and to facilitate the movement of the parts, a ball-bearing 52 is interposed betweenthe hub 50 and the top of the column 46. v

i The carrier is moved intermittently, but always in the same direction, in order to brin'g'the several clamps successively to a point where the heels are loaded and disproduced by ratchet-mechanism including a double or yoke-like lever 54, extending integrally from'the'hub 50. The carrier-member 24 is provided with a series of depending ratchet-teeth 56 spaced similarly to the heel-clamps, and the lever 54 carries, at its outer end, a pivoted pawl 58 which coopcrates with these teeth, a spring 60 con stantly pressing the pawl upwardly to maintain such operative engagement.

The lever 54 is actuated by cam-mechanism comprising a sleeve 61 which mounted to turn freely on a rod 62 fixed horizontally on the frame of the machine. A cam 64, fixed on and rotated by the cam-sleeve 61, engages a roller 66 on one'arm of a bellcrank lever 68, and this lever is pivoted loosely on a rod 70, mounted in stationary position on the frame of the machine. The upper arm of the lever 68 is connected, by a universal joint '72, with one end of a spring-housing 74, while the rod 76 slides through an opening in the other end of the housing and is connected, by a universal joint 84, with the lever 54 (Fig. 7). The

inner end of the rod 76 is provided with a head 78, and a compression spring 80, enclosed within the spring-housing, against this head and against the right-hand end of the hous ng. The expansion of the spring is limited by stop-nuts 82 on the rod.

The cam acts once during each'rotation to swing the upper arm of the lever '68 to the left, thus rocking the lever 54 ina clockwise direction through a space approximately equal to that between t-wo'of the ratchet-teeth 56, and in this manner the carrier is turned sufiic iently to remove one heel-clamp fromthe loading-point and bring the next clamp in succession to that point. The mechanism including the spring 80 provides a yielding connection, which avoids injury to the machine in case the rotation of the clamp-carrier encountersany unusual resistance, owing to the jamming of themachine or any other accidental cause.

A buffer is provided :for arresting the rotative movement of the clamp-carrierat the proper point and without shock; This bufi'er includes a frame of generally triangular form, comprising an upright member 86 and two inclined members 88 and 90 (Figs. 1 and 5). At its lower angle the bufier-frame is pivoted upon one .end of the rod 62. The upper part of the frame is bored to receive a stop-plunger .92 of which the upper end cooperates with the ratchet-teeth 5 6. The lower end of the plunger is fixed to a slideblock 94, which moves in a vertical guideway 96 forming part of the frame-member 86. A spring 98 presses upwardly against the slide block and tends to hold the stop plunger in position for engagement with the ratchet-teeth, as shown i-nFig. l.

A slight lateral yielding movement of'the plunger, when engaged by a ratchet-tooth, is provided by the pivotalmounting ofthe buffer-frame. At the junction between the frame-members 88 and 90 a socket 100' is acts provided which loosely embraces the end of the rod 70, and a spring-pressed plunger" 102, arranged to slide in the frame-member 88, engages the rod and maintains the parts normally in the position of Fig. 1. WVhen the plunger 92 is engaged by aratchet-tooth the momentum of the carrier is absorbed by a rocking movement of the buffer-frame about the shaft 62, which is permitted by the momentary yielding of the plunger 102, the parts being restored immediately thereafter to normal position by the action of the spring 104 which controls the plungerf In order to. prevent recoiling from the stop-plunger 92 a pawl'106 is pivoted, at the upper end of the buffer-frame, in position to engage the rear surface of the same ratchettooth which is arrested by the stop-plunger. This pawl 106 is yieldingly supported by a spring-plunger 108, so that it does not interfere with the advancing movement of the ratchet-teeth into engagement with the stopplunger.

Before each advancing movement or rotation of the carrier it is necessary to disengage the stop-plunger from the ratchet-tooth with which it is in contact, and this is accomplished by cam-mechanism which momentarily retracts the stop-plunger. By means of a pin 110 the slide-block 94 is connected with the upper. end of a link 112, of which the lower end is pivoted to a bell-cranlclever 114i (Figs. 1 and This lever is mounted on a stationary pivot-stud 116 on the buffer frame member 90. The lower arm 118 of the lever 114 cooperates with a pin 120 which projects from the cam 64, this pinbeing so located that, at the proper point in, the cycle of operations of th machine, it encounters the arm 118. and acts, through the connections just described, to draw the stop-plunger 92 downwardly just before the lever 54 is actuated to rotate the clamp-carrier. The continued movement of the pin 120 disengages it from the arm 118, and the stopplunger is thus permitted to rise again, under the influence of the spring 98, in time to arrest the movement of the next ratchettooth 56.

After the arrival of each heel-clamp at the loading position, it is necessary to move the lower clamp-jaw downwardly to release the heel which is held in the clamp, and for this purpose cam-actuated mechanism is provided. On the lower end of each stem 22 is fixed an inwardly-projecting arm 122 (Fig. 2), and each of these arms, in-turn, cooperates with a retractor 124. This retractor is in the form of an upright arm integral with a vertical sleeve 126 (Figs. 1 and 2), the upper extremity of the arm being provided with a lug 128 which overhangs the arm 122 of that clamp which is at themoment at the loading-point. The sleeve 126 slides vertily on a guide-rod 130 mounted on the the frame of the machine.

base-plate of the machine, and the sleeve pivoted to the forked end of a cam-lever 132, which is pivoted on a rod 134: fixed on The other arm 136 of the lever carries a roller 138 which is actuated by a cam 14.0 on the cam-sleeve 61. This cam is so formed that upon the arrival of each clamp at the loading-point the retractor 12 i is drawn downwardly, thus engaging the arm 122 and opening the clamp. The parts are then retained in this position until the next cycle of operations of the machine, whereupon the mechanism acts to release the. clamp-jaw prior to the next partial rotation of the clampbarriei'.

The loading and unloading of the clamps is facilitated by the provision of a loadingtable 1 1-2 (Figs. 1, 3 and i). This table is fixed, in horizontal position, upon an arm 1 projecting rigidly from an upright frame-member 146 which is connected, at its lower end to the base-plate of the machine. The loading-table is set at the level of the upper surface of the lower clampjaw, in the retracted position of the latter, so that a heel lying upon the feed-table may he slid directly, by horizontal movement, into the space between the clamp-jaws, by movement approximately radial with re spect to the clamp-carrier.

The pressed heel is ejected from each clamp-carrier, prior to the introduction of a fresh or green heel, by an outward movement opposite to that by which the fresh heel is introducedf In order to divert the heel so ejected laterally from the feed-table a deflector is employed, in the form of a vertical plate 148 which occupies normally a diagonal position above the feed-table, as shown in Fig. 3. one end, with a'depending stud 150 by which it is pivoted to the outer end of the feedtable, and a spring 154:, coiled about the stud, is connected atone end to the table, and at the other end to a collar 152 on the stud (Fig. 4)- This spring tends to hold the deflector in its normal position, which is determined by a stop-lug 156 depending from the deflector and engaging the edge of the feed-table. The pivotal arrangement just" described is provided in order that the deflector, after performing its function, may be swung aside from the feed-table in order to avoid obstruction to the movement of a fresh heel into the heel-clamp.

To facilitate the introduction of the heels in correct posit-ion in the heel-clamp, a gagemember is provided, which acts also as an ejector to remove the pressed heels. This combined gage and ejector-member comprises a flange 158, shown in dotted lines in Fig. on the outer end of a horizontal plate 160. The plate is adjustablyfixed on the upper surface of a slide 162, which is arranged to move horizontally in a substan- This plate is provided, at

tially radial direction with respect to the The slide 162 is providedclamp-carrier. withsleeves 16% and 166, connected by an integral yoke 170 and arranged. to slide upon a horizontal guide-rod 168. This guide-rod is mounted, in stationary position in a block 172 which is fixed upon the end of the stationary tube 1%. Rotation of the sleeves and 166 upon-the rod 168 is prevented by n arm 174, which projects from the sleeve 166 and is perforated to slide upon a second guide-rod 176 fixed inithe block 172.

The ejector is actuated by cam-mechanism, and for this purpose it is provided with a pin1.78, fi:-;ed in the slide 1.62, by which it is pivoted to one end of a link 180, of whici'i' the other end is pivoted to an arm 182. This arm is fired on the upper end of a rockshaft-184i, which turns vertically within the tube i l. The lower end of the rock-shaft 184 is provided with an arm 186 which is connected, by a universal. joint 188.. with a short rod 190 of whichthe other end is connected to the lower end. an arm192 This is integral'wit-h ii hub 19% which turns on the red B l/and a second arm 196, projecting from the hub, carries a. roller. 198. The roller bears upon theperiphery of a eam'1200 on the cam-sleevey61 and ithe-.engagement between the roller and the cam 1S maintained bya spring 20d attached to the arm .192.

As shown in Fig. 3 the parts are in a position such that the ejectormay act as a. gage,

theflange 158 being in position; between the clamp-jaws,-to beengaged by the breastsurface of the heel. This position may be adjusted, in accordance with the size of the heel,"by movement of the member 160 upon the member-162, theseparts being adjustablysecured together-'by'screws 202, threaded intothe member 162 andpassing through slots in the member 160. I The member 160 is.

i also slotted to clearthe pin 178.

The Yretracted position 18 maintained until another clamp has been brought into position at the loading-point, whereupon the ejector is forced outwardly by the cam 200, thereby forcibly ejecting the heel from the clamp and over the surface of the feed-table. The heel is delivered from the table, by the deflector 184, into any suitable receptacle which maybe provided to receive the dried heels. After this ejecting movement the cam 200 permits the spring 204 to cause the ejector to be partially retracted to bring it to the position of Fig, 73,- r in which it may again act as a gage.

An important feature of the present in vention resides in the use of a manually controlled power-actuated 'means for feeding into the clamp a heel which has been supplied manually to the machine; This mechanism comprises a feed-arm 206 which is fixed upon the upper end of a rock-shaft 208, this rock-shaft being mounted in hearings in the vertical frame-member 1 16. The heel is placed, by the operator of the machine, between two gage-members 210 which are mounted on the feed-arm 206 and formed to engage the lateral surfaces and the rear surface of the heel, as shown in broken lines in Fig. These gagemembers are adjustably attachedto the feed-arm by screw-andslo't connections 212, so'that they may be adj usted in accordance with the sizeof the heel.

The feed-arm is normally retained in the retracted position shown in Fig. 3 by means hich will be described, but when released for operation it is actuated, through the rock-shaft 208, so as to swing inwardly over the feed-table. and yieldingly carry the heel w nch is between the gage-members 210 into the clamp and against the a -615s. This movement is produced by a spring 218 (Figs. 1, 3 and whichis attached, at one end, to the 'frameof the machine and at the other end to a stud 216 which also projects up- "wardly from an arm 21%, thisarm being. fired to the lower end of the rock-shaft 208.

- The operation just described of the feedarm is controlled automatically by the introduction of a heel to'the machine. A tripplate220 is mounted upon one arm of a-yokeshapedmember 222, which is supported by a rod 22 1 which turns in a horizontal bearing-sleeve 226 on the stationary arm l t-1- (Figs- Sand The other arm ofthe memher 222 is provided with a we ht 2 28 which overbalances the tripplate 220, .and thus rocks the latter into, and normally holds it.

in, the position of Fig. 1, in which the outer edge of the trip-plate is engaged by a lug 230 depending from the feed-arm 206. The trip-plate thus normally acts as a detent to prevent operative movement of the feedarm. The downward 'move'ment of the weight 228 is limited by engagement of a lug on this weight, wltha stop-screw 232 fixed in the feedtable, while rising movement of the weight is limited by an adjustable stopscrew 234, threaded in the weight and arloo teed-table and into the clamp which is in position to receive it.

Prior to the rotation of the heel-carrier which succeeds the feed-movement just described, the feed-arm is restored to its normal position. Thisis accomplished by connections with the same cam-mechanism by which the ejector is actuated. A second arm 236. integral with the arm 186, is connected with an arm 238 on the lower end of the rock-shaft 208 by a lost-motion connection which comprises a rod 242 projecting from a head 244 which is pivoted to the arm 236. The rod slides within a sleeve 240 pivoted to the arm 238. This lost-motion connec,-

tion is such as not to transmit any movement to the rock-shaft 208 during most of the movement of the ejector, but when the rockshaft 184 is turned, in a counterclockwise direction, to fully retract the ejector prior to the rotation of the clamp-carrier, the extreme movement of the arm 236 causes the head 244 to engage the end of the sleeve 240 and thrustagainst this sleeve,thereby turn-v ing the rock-shaft 208 to bring the feed-arm to its normal position'and stretch the spring 218. The trip-plate 220 then swings upwardly behind the lug 230 so that upon the next succeeding advance of the ejector the teed-arm is retained in its normal position until again released by the introduction of a heel. I v

An important feature of the present invention resides in an arrangement by which the machine is thrown automatically into operation only if and when a heel is introduced by the operator, the machine then performing one complete cycle of operations and coming automatically to rest. By this arrangement the operation of the machine is timed exactly in accordance with the speed with which the operator is able to build and introduce the green heels or heel-piles.-

For the'foregoing purpose the machine is actuated through clutch -mechanism ar ranged to cause, at each operation, one complete rotation of the cam-sleeve 61. The clutch-mechanism comprises an arm 246 integral with the cam-sleeve (Fig. 6). By means of a pivot 256 the arm 246 is connectt ed to one end of a thrust-link 248, and the thrust-link is provided, at its free end, with a roller 250 and a lug 252. This roller and lug are adapted to cooperate with a series oi drive-lugs 260 projecting laterally from' a worm-wheel 258 which is loosely mounted upon the rod 62. The worm-wheel is driven constantly, by a worm upon a shaft- 262 which turns in bearings upon the frame of the machine. the shaft 262 being geared to a drive-shaft 264 which is provided with a pulley 266- whichmaybebelted to any suitable source of power. The thrust-arm 248 is engaged by a spring-pressed plunger 254, mounted in the hub of the arm 246, which a beveled upper surface adapted to cooperate with the roller 250. hen this surface is in the path of movement of the roller, the latter, in revolving around the cam-shaft, engages and rides upwardly upon the projection 272, whereby it is raised out of engagement with the drive-lugs 260, and the driving-connections between the worm-wheel and the cam-sleeve are thereby interrupted and the cam-sleeve is brought to rest. These driving-connections are restored by swing ing the trip-lever about the stud 270 so as to disengage the projection 272 from the roller 250, and thereby permit the latter to be swung downwardly again into engagement with whichever of the drive-lugs 260 may be passing beneath it at the moment.

The trip-lever 268 is controlled by the action of the feed-mechanism so as to throw the driveclutch into operation it and when a heel has been supplied to the teed-mechanism and has been introduced by the latter to one of the heel-clamps. To this end lostmotion connections are provided between the trip-lever and the rock-shaft 208 by which the feed-arm is actuated. These connections include a two-part link cimiprising a yoke 2'76 (Fig. 5) which pivoted, at one end. to the trip-lever 268.. and a rod 274 which slides in the yoke and is pivoted to the stud 216 on the arm 214. which arm. as before described. is fixed to the lower end of the rockshat't 208. Vl hen the tecd-arin swings inwardly to introduce a heel to one of the feed clamps the rod 274 slides freely in the yoke 276 until the head 278 of the rod is arrested by engagement with the yoke. Thereupon the yoke also move", thus swinging the triplever out of" e1, roller. subsequently restore to its normal position. the head ol the r i 274. utter the necessary amount of lost motion. tll the yoke outwardly again. thereby return; 1' the tripdcve into operative position. and this ccurs before the clutch completed a rotation of the cauisleeve. so that the trip-lever is in position to encounter the roller 250 when the latter has completed one revolution.

shown in the drawings,

wheel'258 and the mechanism by which it is constantly actuated. ,The operator places a moist and newly assembled heel'o-r heel-pile I between the gage-members 210 of thefeedarm and presses down upon this heel so as to depress the trip-plate 220. Thereupon the feed-arm swings inwardly, carrying the heel with it across the feed-table, while'the del flector 148 swings outwardly from the. path of the heel. The heel is thus carried into the space within the waiting clamp, of whichthelower jaw is held in depressed position by the retractor 124:, as shown in Fig. 2. The

feed-movement of the heelis arrested by yielding engagement of the breast-surface of the heel with the gage-flange 158.

As the feedarm completesthe movement just described,-the trip-lever 268 is moved to throw the drive-clutch into operation, and

the cam sleeve thereuponcommences to rotate; This rotation causes the retractor 12 1 to rise and thus release the lower aw of the clamp at the feedingpoint,so that the heel just introduced is gripped and pressed. At.

or about the same time the ejector is retracted and the feed-arm is swung back again to its normal position, while the stopplunger 92 is retracted from engagement with the ratchet-tooth 56 on the clamp-carrier. The carrier is then turned through the space between two adjacent heel-clamps, and the stop-plunger rises in position to again operate. In the meantime the triplever 268.

has been brought back to operative position coin'cidently with the return of the feed-arm.

to its normal position.

Thepartial rotation of the carrier brings the next heel-clamp in order into position at the feeding-point. 7 tinned rotation of the cams. the lower jaw Through the con of the said clamp is retractedby the retrac-,

tor 124C, and the ejector is then moved outwardly. At the commencement of the operation of the machine this movement of the ejector is idle, but after the machine has been in operation long enough to cause all of the heel-clamps to have become filled, this action of the ejector eXpels the pressed heel from the clamp in question. The ejector is then retracted into position'to act as a breastgage for the fresh heel which is next tobe introduced to the clamp. The triplever then throws the drive-clutch out of operation, and the cycle of operations of the machine is thus completed.

It willbe understood that the machine is provided with a considerable number of clamps in order that each heel may be held under pressure for a time sufficient for sub. stantially drying the paste. In the illustrated machine this time is that requisite.

for the performance of thirty-two cycles of operation, but the numberof clamps. em-

ployedmay be: varied in accordance with the desired speed of operation, and the nature of the paste employed in the heels.

A. valuable feature of the feed-mecl'ianisni of the present machine residesin the fact that it avoids the necessity of the operator introducing the heels by hand between the clamp-jaws, and eliminates the possibility of I injury to the operators hand. through care lessness in operation, it being impossible for the clamp-to close and the clamp-carrier to move until after the heel has been removed from the hand and the control of the operator by the action. of the feed-arm.

The general'arrangement of th s the machine has the adv t that the mm chine may be located entirely beneath the level of the table upon which the operator assembles the lifts of the heel, where the mechanisms operating directly upon the clamps and the heels while the clamp-carrier is stationary By. thisarrangement these operations are performed with greater certainty and with the expend ture of less power than where some or all of the move ments involved in these operations are produced indirectly, through cam-devices operated by and during the rotative movement of the clamp-carrier. v 7
