53 Claims.

This invention relates to machines for manufactm'ing shoes or other footwear and in some aspects especially to machines for making footwear in which the lasted upper is secured to the sole by cement or other adhesive, the term sole being commonly used herein to include the insole of some kinds of shoes. It is herein shown as embodied in a machine for carrying out certain steps in the manufacture of gaiters or overshoes and this constitutes an important field of use, although the invention is not limited to the manufacture of this or any particular class of footwear.

The machine of my invention includes a novel form or support upon which the sole and upper may be located and properly assembled preparatory to lasting the upper by overwiping its mar upon the sole and securing the overwiped margin of the upper permanently in position by It will be understood that the margin of the upper and the surface of the sole, or either of them, may be coated with an adhesive effective, upon the ap- J clamp, are provided for holding the upper in adjusted position and such means are arranged to be rendered efiective by the operator preliminarily to the power operation of the machine.

The machine herein shown as an embodiment of my invention is adapted to the manufacture of footwear characterized by a concave shank and a heel portion of substantial height formed by the upper and the sole, necessitating a heel breast surface of substantial dimensions on the T? sole extending at an angle to other portions of the sole. To this end, the shank and heel breast portions of the form are of a yieldable character and may be distorted or expanded for the purpose of yieldingly following the sole and up- 1 per material supported thereby and applying fluid pressure thereto accurately and uniformly to press the sole against the margin of the upper, whatever the thickness of the materials may be. A novel feature of the invention is to be recognized in fluid pressure means arranged to act on the inner face of the sole to press the sole against the overlaid margin of the upper.

Another important feature of the invention consists in a form having a defined heel-seat area, a concave shank and an intermediate angularly-disposed heel breast portion, together with means for accurately conforming a flexible sole to the aforesaid contour thereof and holding the conformed. sole in place while the margin of the upper is overlaid thereon. A machine of this construction presents the important advantage that the lasting operation may be effected from the heel-seat to the ball line of the shoe in the consecutive steps of a single operation carried out upon a sole and upper brought once for all into proper relation. In the machine herein shown, the heel-seat portion is overwiped, the sole is con'ormed to the heel breast and shank portions of the form, and the shank portions of the upper are overwiped, all as consecutive and related steps, the lasting steps progressing from the heel-seat and supplementing each other as the upper material is overwiped and secured in place.

My invention further includes as one feature a clamping device or pad arranged to be automatically positioned for holding the upper in place adjacent to the shank of the shoe after the heelseat has been formed and preparatory to further over'tviping of the upper. he pad is arranged to be mechanically actuated and controlled by the operator so that it is brought into action at a point in the cycle of the machine affording opportunity for the proper adjustment of the upper preparatory to overwiping the same along the sides of the shoe in advance of the heel-seat.

The machine of my invention also includes heel-seat wipers arranged to be m chanically operated for overwiping the margin of the upper about the heel-seat and serving also to exert the pressure upon the heel-seat desirable to insure the adhesive union of the upper and sole. The machine shown includes also a shank forming member arranged to be mechanically operated after the heel-seat been completed to conform the sole to the heel breast portion and the concave shank portion of the form. Means are provided for moving the shank former into place in a path adjacent to the position occupied by the the heel-seat wipers at the conclusion of the heelseat forming operation and for maintaining the shank former securely in place during the ensuing steps of the machine cycle. This combination and mode of operation is believed to be novel and of particular advantage in the manufacture of footwear in which the upper and sole are fastened by an adhesive.

In still another aspect my invention comprises mechanism operating to form a heel-seat in footwear and to conform a sole to a shank contour therein, in combination with means for lasting the heel breast and shank portions of the upper as subsequent and related operations. There is herein disclosed, however, novel lasting mechanism for use upon the shank portions of footwear which constitutes a feature of my invention capable of general application. In its more specific aspect, the heel breast and shank wiping mechanism shown comprises a pair of wiping devices arranged to be positioned upon opposite sides of the shoe and movable simultaneously toward each other to overwipe the projecting margin of the upper upon the edges of the sole which has previously been conformed to the corresponding surfaces of the form. For reasons of compactness and efiiciency, it is desirable to associate the shank wiping devices with the shank former above mentioned and, as herein shown, these may both be mounted on a carrier and brought simultaneously into operative position.

The illustrative embodiment of my invention comprises an organized machine including the numerous mechanisms above discussed, cooperatively related and timed in their operation to carry out progressively the consecutive steps of shaping and fastening by adhesive the sole and upper of footwear from the rear end of the heelseat, throughout the heel breast and shank portions substantially to the ball line. The cycle of the machine and the mechanism whereby it is carried out possess many features of novelty which will be pointed out in connection with the more specific description of the machine.

These and other features of the invention will be best understood and appreciated from the following description of a preferred embodiment thereof, selected for purposes of illustration and shown in the accompanying drawings, in which Fig. 1 is a view of the machine in perspective as seen from the right;

Before proceeding to a detailed description of the illustrated machine, it will be convenient to outline briefly its operating cycle. After the upper has been properly positioned upon the form 65 carried by the jack 50 and the insole located on the bottom of the form and held in place by air suction, the operator depresses the treadle which operates first to bring the counter clamp or band yieldingly into engagement with the back of the upper, thus retaining it against displacement during the ensuing operations. Continued depression of the treadle thereupon trips the clutch and hee1-seat wipers 22 are advanced to wipe the upstanding margin of the upper over the heelseat of the insole. When the heel-seat wipers are fully advanced, the jack is elevated by power so that the overwiped material and sole are compressed against the under face of the wipers and the machine is brought to rest automatically with its parts in this position.

When the starting treadle is depressed for the second time, the side or shank clamps 150, which have been latched out under tension, are tripped and so permitted to move into engagement with the upper upon opposite sides of the shank. The treadle also operates to swing down the arm 110 carrying transversely-movable shank wipers and a convex form 122 for molding or shaping the insole into conformity with the concave shank face of the shoe form upon the jack. When these two operations have been effected by the movement of the treadle, the clutch is tripped for the second time and the mechanical cycle completed. The arm carrying the shank wipers is first looked rigidly to the frame in position of pressure. The shank wipers are then moved inwardly, overwiping the margin of the upper along both sides of the shank, and a flexible, water-filled section of the shoe form is mechanically caused to bulge or flex so that the overwiped margin of the upper is pressed forcibly into contact with the conformed sole. After an interval, the shank wipers are moved outwardly, the jack lowered to its initial position, releasing the pressure of the shoe bottom against the wipers, the heel wipers are ref supported at a convenient height upon a column 10. The side members of the frame are connected at their upper ends by a fiat top plate 14, between which and the top side members is interposed a pair of guide plates 16, each having a guideway formed in its inner edge for the reception of a wiper slide 18. The wiper slide is mounted for movement in a horizontal path from front to rear 1 and carries at its forward end a pair of wiper hum in their wiping movement about a point coin .1

ciding substantially with the center of the rear edge of the heel-seat of the shoe being operated upon. Each wiper carrier 20 is connected at its rear end by a stud 24 with a slotted link 26 which, in turn, is connected to the top plate by a down: wardly-extending bolt 27. 26 permit the wiper slide 18 to be moved from its rearmost position forwardly to bring the wipers 22 adjacent to the sides of the heel-seat of the shoe to be operated upon without imparting transverse movement to the wipers, but when the ends of the slots contact with the bolts 27 the wiper carriers 20 are oscillated with a scissors motion to bring the wipers in, overwiping the marginal edge of the upper material upon the heel- The slots in the links seat. The rever e movement of the wiper slide 18 occurs after the lasted shoe has been lowersc out of contact with the wipers 22, and in the final rearward movement of the slide the bolts 27 encounter the forward ends of the slots in the links 26 and act to swing the wiper carriers outwardly into their initial position. When the wiper slide 1 advanced and the wipers 22 located in their inner and operative position, the wiper carriers as are supported against upward pressure by the forward ends of the fixed guide plates 16.

The head frame 12 is provided with bearings for a horizontal cam shaft 40, upon which are mounted cams for operating the wiper slide 18 and the other instrumentalities of the machine, to be presently described. The wiper slide 18 is provided on its lower face with a pair of spaced lugs, between which is received the upper end of a cam lever 28 arranged to oscillate upon a transverse shaft 30 disposed parallel to and above the earn shaft 40 and extending between the side members of the frame. The lower arm 32 of the lever 28 is provided with a cam roll 34 which runs upon the periphery of a cam disk 36 which is formed integral with a barrel or hub 35 fastened on the shaft 40. A tension spring 33 extends between the arm 32 and a stationary pin set the machine frame and acts to hold cam roll as always in contact with the contour of operating cam 36. i

The shoe to be operated upon is supported upon a 59 pivotally mounted for adjustment by means of a transverse pin 51 which extends between spaced flanges forming a part of the jack ca riage 52. The jack carriage is mounted for limited vertical movement in ways formed in a front plate 54 which is bolted to the machine head 12. The body of the jack carriage is provided with a vertical bore threaded at both ends for the reception respectively of a lower threaded plug 55 and an upper threaded plug 56. The rear face of the jack carriage 52 is slotted to admit one arm of a cam lever 59 into the vertical bore this is engaged between the inner end of the lower threaded plug 55 and a spring bearing member 58 is yieldingly positioned by a stiff compression spring 57 interposed between the side of the bearing piece 58 and the lower end of the threaded plug 56. The cam lever 59 fulcrumed upon a transverse shaft 60 extending between the side members of the frain 12 and is provided with a cam roller 61 arranged to run upon the periphery of a cam disk z'l i pinned to the cam shaft is. A tension spring 62 serves to intain the cam r011 61 at all times in engagement with its operating cam. It will be noted that when the cam lever 59 is rocked in a clockwise direction carriage 52 and the parts carried thereby will be yieldingly elevated through the compression spring 57, and when the cam lever 59 is rocked in a reverse direction the jack carriage will be lowered.

Upon the upper end of the 5G is detachably secured the form 65 upon which the shoe is to be built. In general contour this conforms to the heel end shank portions of a last of the size and style of the shoe to be treated and may readily be interchanged for forms of different shape in accordance with the requirements of the work. The upper end of the jack 50 is formed as a rib designed to be embraced by flanges formed integral with the form 65 and the form is locked to the jack by a removable transverse pin 6'? which extends through the flanges of the form and the end of the jack.

-The form 65, as best shown in Figs. 1 and 2 is provided with an elevated 11 el-seat portion to which is secured a heel-seat plate 66. The form herein shown is provided with a shank of pronounced concavit the heel-seat portion of the form having a substantially vertical breast face. The rear portion of the orm is provided wi h vertical air passages 68 which open through the heel-seat plate 66 in segmental suction openings. The passages 68 communicate directly with a transverse passage 69 in the top of the lack 59, a gasket being provided for insuring, an air-tigl1t joint. The passage 69, in turn, communicates with a downwardly and forwardlyextending tube 76 which enters the body of the jack 5G and communicates with a verticallydisposed air passage 71 opening through the bottom of the jack. The jack carriage 52 is provided with a downwardly and forwardly-inclined air passage '72 surrounded a its upper end by a gasket. The jack carriage is also provided with a ver 'ical adjusting screw 53 which bears against the lowerface of the jack 5G in advance of its fulcrum pin 51. By setting up the adjusting screw 53, the jack 5b is rocked about this pin so as to form a tight seal by means of the gasket son the air passage 71 in the jack and the air passage '72 in the carriage. The passage 72 is connected by means of a pipe 73 to an pump 48 mounted behind the machine frame 12 and driven by a pulley 49 from any sui able source of power. The action of the pump through the connections above described is to create a artial vacuum beneath the heel-seat plate 66 of the form 65 so that an insole placed upon the heel-seat plate will be maintained by suction thereon.

Between the sides of the form '35 and in the portion thereof is provided a longitudinally extending recess which stops short of the ends of the sole-supporting face of the form. This recess extends into the breast face of the heelseat portion of the form beneath the heel-seat plate 66 and is designed for the reception of an elongated hollow flexible fluid container or pad 'Z l. This pad is rectangular in cross section, longitudinally curved and provided with an upper concave wall 75 which forms, in effect, the shank heel breast faces of the form. As best shown in Fig. 7, the pad T l is provided at its heel-seat end with a clamping bar or filler piece '76 which is attached by a screw to the forward edge of the heel-seat plate 66 and is thus anchored in place thereby. At its forward end the pad is pro vided with a similar filler piece '77 which is con nected by a screw to an end plate and anchored in place by a transverse plate 78 which extends across the form and overlies the recess in which the pad l4 contained. In its lower face the hollow pad is provided with a filling plug '79 by which. it may be filled with water or oil before being assembled in the form 65. The recess in the form is shaped to receive beneath the pad a head which is recessed to receive the filling plug 79 to bear upon the pad at both sides thereof. The form 65 and the jack 50 are provided with aligned vertical bores in which is located an operating rod 81 normally out of contact at its upper end with the head 80 but adapted to engage and force the head upwardly at the proper time in the cycle of the machine when the hollow pad 74 is to be flexed. At its lower end the operating rod 81 rests upon an adjustable stop screw 82 projecting upwardly from a cam lever 83 which is mounted to swing about the fulcrum ready been described as pin 51, already mentioned. The cam lever 83 carries a cam roll 84 at its rear end which is arranged to run upon the periphery of a segmental cam 85 bolted to the righthand face of the cam disk 64, as seen in Fig. 6. As will presently appear, the cam 85 is designed to swing the lever 83 to elevate the operating rod 81 and press on the hollow pad 74, causing it to exert an additional pressure upon the margins of the insole in the shank. after the overwiping action of the shank wipers.

The counter clamp mechanism will now be described. This includes a transversely-disposed flexible band 90 which is supported at the forward end of a horizontally moving slide by a pair of side links 91 and a centrally-disposed supporting slide 92, best shown in Fig. 5. The counter clamp slide 93 is forked and provided at its edges with ribs arranged to fit in corresponding guideways in the inner edges of guideway bars 94 which are bolted to the lower face of a flanged web 95, formed integral with the side members of the head frame 12 and located beneath the guide plates 16 for the wiper slide already described. The slide or 92 is mounted in an open channel formed in the upper face of the slide 93 and is provided at its forward end with an Lip-turned car which is connected by a screw to the center of the clamping band 96. The links 91 are permanently connected to the outer ends of the band 90 and are free to swing transversely upon pivot pins extending upwardly from the slide 93. The result is that when the latter is advanced the band 90 is conformed accurately to the counter part of the form 65, thus clamping and firmly holding the upper material in place thereon. The slide 93 is provided with a downwardly-projecting swivel head 96 which is connected through a substantially horizontal link 97 with the upper end of an arm 98 pinned to the shaft which has alserving as a journal for the wiper slide cam lever 28. At an intermediate point the arm 98 is provided with a swivel head 99, through which extends an operating rod 100.

, A compression spring 89, interposed between the head 99 and a nut on the end of the rod 100 supplies a yielding connection between the two. At its to ward and lower end the operating rod 100 is connected to the upper end of an arm 101 pinned to the inner end of a transverse shaft 162 journaled in a boss projecting outwardly from the left side member of the head frame 12. At its outer end the shaft 102 is pinned to a forwardlyextending arm 103 which has a lost motion connection with the upper end of a treadle rod 105 connected at its lower end to a treadle 106. A tension spring 104 acts normally to elevate the arm 103 and the treadle and to rock the shaft 102 in a counter-clockwise direction. It will be seen that upon depressing the treadle 106 the shaft 102 will be rocked in a clockwise direction, as seen in Fig. 3, and through the connecting mechanism above described the slide 93 will be yieldingly advanced and the clamping band 90 brought into operative position about the counter of the sition. It will be understood that the treadle 106 must be fully depressed to trip the machine and, consequently, the clamping band is held in its operative position until the working stroke of the heel-seat wipers is substantially completed. The machine is brought to rest automatically with the heel-seat wipers 22 in their inner and forward position, as shown in Figs. 4 and '7, by mechanism which will be presently explained, whether or not the treadle is released. However, in order to restart the machine for the second portion of its cycle, the treadle must be released and the clamping band 90 is, accordingly, retracted by the action of the spring 104 to its initial position, as shown in Fig. '7.

The side or shank clamping devices for the upper will now be described. These comprise a pair of pads 150', each of which includes in its structure a comb plate with upstanding spring fingers 158, as shown in Fig. 3, which are encased in a textile envelope. Each comb plate has,

a downwardly-extending shank mounted to swivel in a boss formed at the upper end of the vertical arm 151 of one of the bell crank levers 151-152. Each of these bell crank levers is mounted to swing about a horizontal stud 153 projecting forwardly from the sides of the machine frame 12. A torsion spring 154 surrounds each stud and tends normally to swing the bell crank levers inwardly, carrying the pads 150 into yielding engagement with the upper upon the form upon opposite sides thereof adjacent to the shank.

The outwardly-extending arm 152 of each bell crank lever is pivotally connected to the upper end of a short vertical link 155. On the right hand side of the machine the link 155 is connected tothe end of the forwardly-extending arm 156 of a cam lever 156-457, which is pinned to the right-hand end of the shaft 60, already referred to. On the left-hand side of the machine the link 155 is connected to a forwardly-extending arm 163 which is pinned to the left-hand end of the same shaft. The rearwardly-extending arm 157 of the cam lever carries a cam roll 159 arranged to run upon the periphery of a disk cam 160. The cam 160 is formed integral with a barrel or hub 161 fast upon the main cam shaft 40', being held thereon against endwise movement by a bolt 41. A tension spring 162 maintains the cam roll 159 always in engagement with the cam disk 160 and supplements the action of the torsion springs 154 upon the shank clamping mechanism.

In the initial stopped position of the machine, 1 the cam 160 holds the cam lever arm 15'? in an timing of the earn 160 is such that the machine comes to rest at the conclusion of the first portion of its cycle after its drop-01f portion has passed beyond the cam roll 159. The cam lever is arranged to be tripped in the depression of the treadle to restart the machine, as will be presently explained, and when this occurs the

springs

154 and 162 are effective to move the pads 150 into clamping engagement with the sides of the upper. This occurs during the initial depression The cam 160 is provided with an res Elli) heel-seat faces of the latter.

of the treadle 106 and before the clutch is tripped for restarting the machine for the concluding portion of its cycle. The result is that the upper is yieldingly clamped to the sides of the form adjacent to its and the operator is given an opportunity of straightening and adjusting it before the power operation of the machine is resumed.

The mechanism for tripping the shank clamp-- ing pads associated with and forms a part of the mechanism for controlling the position of the overhead arm carrying the shank shaping and lasting mechanism. The latter will, therefore, be described before explaining the tripping mechanism.

A forked and ribbed arm 110 is pivotally mounted at its rear end upon a transverse shaft 111 which extends between ears rearwardly projecting from the upper portion of the head frame 12. Beneath and behind its axis of movement there is secured to the arm iii) an angle bar having a rearwardly extending arm 112 and a forwardlyextending arm 113. The rearwardly-extending arm 112 is connected to a cable 114, from which. is suspended a counter weight 115, the cable being guided over a suitable idler pulley mounted in the frame 12. The forwardly-projecting arm 113 acts as a stop to limit the upward swinging movement of the arm 116 by engaging the rear face of the frame 12. The arm 110 carries at its free end the shank forming and wiping mechanism and is normally maintained by the counter weight in an elevated or inoperative position, as shown in Figs. 1 to 3.

The arm 110 is provided with longitudinallyextending ribs at each side and at its free end with a downwardly offset head 118. The design of the arm is such that it may be lowered to a substantially horizontal operative position in which it passes over the top plate 14 and preposed slotted rib 119 through which project a pair of parallel, transversely-disposed rods 120. The shank mold or former comprises a verticallydisposed plate 122 shaped at its upper edge to fit into the slot in the rib 119 and having a pair of undercut recesses in its upper edge arranged to pin is mounted in the forward part of I e 113 arranged to extend downwardly into a socket in the upper edge of the shank former 122 for the purpose of detachably retainit in position. The shank former 122 is ged at its lower edge and convex in contour to cooperate with that portion of the concave contour of the form bounded by the shank It will be understoothat other shank formers of different contour may be interchangeably substituted in accordance with the character of the footwear being manufactured.

transversely-movable carriers 124 are mounted to slide upon the cross rods 1.20 and each is provided with a downwardly-extending longitudinal flange 125, to the inner face of which det "hably bolted a side wiping shank mold wipe-r 126. The latter are retained in place by clamping bolts 127 which pass through the flu 125. In contour the wipers 126 correspond to the contour of the shank former 122. In initial position the carriers 124 occupy positions upon the outer ends of the rods 120, being spaced from each other sufficiently to position the wipers 126 at some distance from the sides of the upper assembled upon the form 65. When the wipers 125 are moved inwardly, in the manner to be presently described, they cooperate with the shank former 122 to cover substantially the whole width of the shank of the shoe, including particularly its outer margin, and in this final position they be spaced slightly from the opposite sides of the former 122, as shown in The shank wipers 126 are actuated by mechanism which will now be described. Each of the carriers 124 is provide-:1 with rack teeth 128 in its rear face which mesh with separate pinions 129 fast to the lower ends respectively of a pair of vertical shafts 130 mounted in the rear part of the 118. Each shaft 130 is provided near its upper end with a second pinion 131 and these pinions are arranged to mesh at opposite sides of a rack slide 132, guided for horizontal movement in ways formed partly in the head 118 and partly in a cover plate 139 secured thereto. The rack slide 132 is adjustably connected by a long screw 133 to a rectangular head 134 movable longitudinally in the arm 110. A fixed stroke is imparted to the head 134 and it will be apparent that the lateral position of the carriers 124 and the limits of its stroke may be adjusted by turning the screw 133 to move the rack slide 132 nearer to or further from the head 134. The head 134 is pivotally connected at its rear end by a cross rod 135 to a link 136 and this, in turn, is connected at its rear end to an upwardly-extending operating lever 142 journaled to swing upon the shaft 111, which constitutes also the axis of movement of the arm 110. A tension spring 140 connected to the arm and acting through the link 136 tends at all times to move the head 134 forwardly in the arm.

The arm is arranged to be positively locked in its lower or operative position by the cross rod 135, which for this purpose is provided at its outer ends with looking heads 137, each of which includes a hardened roller adapted to be drawn rearwardly into engagement with a hook 138 securely bolted to the cover plate 14 upon either side of the arm 110. In other words, after the arm 110 has been lowered to the operative position shown in Figs. 7 to 9 and the head 134 begins to be moved rearwardly in initiating the inward wiping movement of the shank wipers 126, the arm 110 and all the instrumentalities carried thereby are positively locked in operative position by the en agement of the locking heads 137 with the hooks 138. The pressure applied through the sole to the head 118 is thus resisted by this positive and efficient connection and depends in no way upon the strength or accuracy of the mechanism utilized for swinging the arm 110 into its operative position.

The lever 142 which has been referred to as journaled upon the shaft 111 is extended downwardly in the form of a laterally offset arm 143 and this, in turn, is pivotally connected to a forwardly-extending rod 144 which passes through the upper end of a cam lever 146 journaled upon the shaft 30, as shown in Fig. 6, and provided at its lower end with a cam roller 147 arranged to run on the periphery of a cam disk 148 pinned to the cam shaft 40. At its forward end the rod 144 carries an adjustable stop sleeve 145. The cam roller 147 is maintained in engagement at all times with the periphery of its cam 148 by a tension spring 1&1. When the arm 110 occupies its elevated poo. ion, as shown in Fig. 2, the stop sleeve 1% is spaced a substantial distance from the upper end of the cam lever 146 and the lost motion permitted allows the arm 11-0 to be swung to and from its operative position without obstruction. When the arm 110 is lowered into its operative position, the'inner end of the stop sleeve 1 15 is'brought into substantial engagement with the upper end of the cam lever 1&6 so that when the latter is rockedby its cam it is at once effective to rock the lever1 i2 rearwardly, locking the head 118 in position and operating the shank wipers.

Upon the outer right-hand end of the shaft 111 is mounted a rocker 1 ember having a forwardlyextending arm 166 and a rearwardly-extending The rearwardly-extending arm is provided with a hub in which is journaled a short horizontal shaft 168. Fast to the righthand end of this shaft is a dog 169 having a recess adapted in one position of the dog to engage a lug 116 projecting transversely from the arm at a point above its axis of movement. Upon the inner end of the shaft 168 is provided. an upstanding arm 176 which stands in the path of an adjustable contact bolt or stud 38 threaded into the rear face of the wiper slide 18. The arrangement is such that when the wiper slide occupies its initial and rearmost position the dog 169, through the arm 170, is positively held from engaging the lug 116 on the arm 110 so that the oscillation of the rocker member 166167 takes place idly so far as the arm 110 is concerned. On the other hand, when the wiper slide 18 occupies its forward position, as it does at the conclusion of the first portion of the cycle of the machine, the arm 1'70 is permitted to move forwardly to such an extent that the dog 169 will engage the lug 116 and swing the arm 110 into its operative position.

There are two operating connections to the arm 166 of the rocker member. The first is a treadle rod 178 which is hooked over a pin projecting inwardly from the free end of the arm 166 and extends downwardly to the treadle 166. Accord ingly, the rocker member is oscillated each time the starting treadle is depressed. In the depression of the treadle for initiating the cycle of the machine, the oscillation of the rocker member is idle since the dog 169 is then maintained in its inoperative position and the cam lever 157 is held against oscillation by its cam 160.

The second operating connection to the arm 166 is power operated and comprises a ver icallydisposed rod 186 which extends at its lower end into a sleeve or barrel 181, being connected thereto through an adjusting screw 182 threaded into the upper end of the barrel 131 and arranged to be locked in adjusted position by a check nut. At its lower end, the barrel 181 is pivotally connected to the rear end of a cam lever 183 journaled to swing freely upon the shaft 69 and provided at an intermediate point with a cam roll 184. The cam roll is arranged to run upon the periphery of a cam disk 185 which is formed integral with the hub 161 and the side clamp controlling cam 160. A tension spring serves to maintain the cam roll 18 1 at all times in contact with the periphery of the cam disk 185 and the timing of the cam is such that the rocker member 166167 is oscillated early in the second portion of the machine cycle to swing the arm 110 by power into its shank-conforming or operative position. The full throw of the cam is imparted to the rocker member and, consequently, to the arm 116 before the locking rod is displaced rearwardly, and thus positive assurance is had that the arm 110 shall be properly located in operative position before the locking heads 137 engage the stationary hooks 138.

The arm 166 of the rocker member is connected through a downwardly-extending iinl; 1'22 to the forward end of a second rocker member 173 pivotally mounted upon the outer end of the shaft 36 and provided at its rear end with a tooth 174. The tooth 1'74 of the rocker is designed to engage an angular tail or extension 1'75 upon the free end of the cam lever 15? when the latter occupies its initial or elevated posh tion and to prevent the cam roll 159 from following the drop-ofi portion of its cam 160 when the latter is rotated in the initial portion of the machine cycle. A tension spring 176 connected to the forward end of the rocker 1'23 tends always to maintain it in looking engagement with the cam lever and acts in opposition to the thrust of the link 172 when the rocker 166-167 is moved in a counter-clockwise direction. As will be apparent from. the foregoing description, the oscillation of the rocker 173, when the treadle 106 is depressed in initiating the operation of the machine, is merely idle since the cam 160 does not permit movement of the cam lever.

Under these circumstances, the tooth 174 is disengaged when the treadle is depressed reengaged when the treadle is released. However, when the treadle 106 is depressed for restarting the machine in the second part of its cycle,

the cam 160 has rotated to a position in which the cam lever 15'? is free to move and, consequently, in this depression of the treadle the cam lever is tripped and the side clamps permitted to engage the upper on the form 65. Continued rotation of the cam returns the side clamps to initial position and brings the cam lever 15'? back to its latching position at the conclusion of the machine cycle.

The main shaft 40 of the machine may be driven from any convenient source of power and is herein shown as provided upon its left-hand end with a roller or Horton clutch of which the driving member includes a sprocket wheel. 190. As best shown in the rear view of the machine of Fig. 6, the sprocket wheel is permanently secured to a rotary driving member 191 journaled to turn freely upon the shaft 410 and recessed at its outer end to receive the d-iven member 192 of the clutch which is pinned to the outer end of the shaft 16. Between the driving member 191 and the driven member 192 is interposed a roller cage 193 containing a plurality of clutch rollers which are received in tapering recesses formed between the opposed faces of the driving and driven members. When the roller cage is moved to locate the rollers in the wide or deep ends of its recesses, the clutch is disengaged and the driving member runs freely. The roller cage is maintained in this position by a tripping lever Cir 196 having a hooked end adapted to engage one or the other of two

teeth

194 and 195 projecting from the periphery of the roller cage 193. When the tripping lever is elevated to disengage one of the teeth of the roller cage, the latter is at once turned to move the rollers into the narrow sion spring which is contained in a circumferentially extending recess in one side face of the cage, as shown in dotted lines in Fig. 3.

The clutch trpping lever 196 is pivotally mounted on the left side of the machine frame and urged at all times into engaging position by a tension spring 19'! secured to its forward end. The lever 195 is lifted by a hooked latch piece 198 pivotally connected to the rear end of the arm 193 and a ranged to engage a pin 199 on the lever 196 when the arm 103 is rocked in a clockwise direction by the depression of the treadle 106. The latch piece is extended downwardly beyond the end of the driven member 192 and the latter is provided with a pair of diametrically located ins 201 which are designed to contact with the end of the latch piece 198 when the machine is set in operation and to disengage it from the pin 199 of the tripping lever 196. This is a well known expedient for restoring the clutch tripping lever to operative position as soon as the driven shaft has once been set in motion. A pawl 200 is pivotally mounted upon the side of the tripping lever 196 and designed to prevent reverse slipping of the roller cage by engaging teeth in. the periphery thereof.

The sprocket wheel 190 is driven through a sprocket chain. 202 from a driving sprocket 203 upon the outer end of the shaft of a reducing gear unit 294 which is mounted on a bracket projecting rearwardly from the machine frame and belted to a motor 205 carried by a bracket secured to the base of the machine. The driven shaft of the gear reducing unit 204 is provided with a pul ley 206 from which the air pump 48 is driven by a suitable belt.

The machine herein described may be employed with advantage in the manufacture of various types of footwear, and in order to make its manner of operation clear this will be outlined in connection with footwear of the gaiter or overshoe type such as is shown in Fig. of the drawings. T..- s shoe comprises a flexible sole 210 reduced in thickness about its margin and thus provided with a fea her 211, which it is customary to coat with an adhesive cement before presenting to the machine. The upper 21% herein shown is of rubberized fabric and is similarly provided with band of cement 215 about its margin. In Fig. 10 the shoe is represented as having been operated upon by the machine of the present invention and in this process the sole 210 is shaped to present a heel-seat 216 merging into a substantially vertical breast portion 217 and a concave shank portion 218. The margin of the upper 214 is overwiped about the heel-seat 216 of the sole, overwiped upon the heel breast portion 21'. of the sole and overwiped upon the concave shank portion 218 of the sole. The overwiped margin is subjected to pressure so that the upper and sole are permanently united from the rear of the heel-seat to substantially the ball line of the shoe.

The construction of the machine and the manner of its operation will be more clearly understood from a summary of the successive steps carried out in producing the partially finished shoe shown in 10. The cemented sole 210 is first placed by the operator upon the upper face of the form 65, where it is immediately securely held by suction of the openings 68 in the heelseat plate. The upper 21 i is next placed about the form with its cemented margin projecting above the heel-seat of the sole and the back seam is straightened. The operator thereupon depresses the treadle 196 and in the initial part of its movement the counter clamping band 99 is brought into clamping engagement with the rear of the upper, preventing displacement there of. In this movement of the treadle, the rocker member 166-187 is also oscillated but in this instance its motion is entirely idle. In the continued depression of the treadle, the clutch is tripped and the cam shaft 40 set in operation, whereupon the heel-seat wipers are advanced and the heel-seat lasting operation completed. In the concluding portion of this part of the cycle, the cam 64 operates to elevate the jack, thereby subjecting the overwiped and cemented material to mechanical pressure suficient to insure permanent adhesion thereof. The starting treadle is then released, whereupon the counter clamping band is retracted although the heel-seat wipers remain in their forward position with the work held pressure. The machine is automatically stopped by the enga ement of the tooth 195 by the trippin lever 196.

The treadle is now depressed to restart the machine and in its initial movement the counter clamping band again brou ht into operative position. althou h its action on the up per is unnecessary at this stage of manufacture. Also. in the initial movement the tr adle the rocker member l6616'7 is moved with it rocker member 173. so the lever 15'. is trip ed and the side clamping pads 150 are permitted to swing into clampin enea ement with the upper along the of the sh ank. The operator is thus afforded an oonortun adiust and straighten the upper proceeding with the depression of the treadle whic. tiates the second. portion of the machine cycle. As the treadle continues to be depressed. however, the c utch is tri ped for the time and the rotati n of the shaft 19 is cont nued.

When the machine is restarted. the cam 185 at 115 once acts through connections described to rock the rocker member 166-167 in a clockwise direction, and since the wiper slide las carr d the stop screw 38 forwardl th is now in position to enga e the lu 116. swinging the arm 119 downwardly and causing the convex shank former 122 to mold or shape the sole .210 into the concave shank portion of form 65 and into conformity with the vertical face of the heel breast portion thereof. soon as arm has reached this position, the e n. 143 a ts to move the head 13% rearwardly. notin the locking heads 13"! into lockin engagement with the stationary hooks 138 and thus rigidlv lockin the arm 110 in its position of pres ure. Continued action of the cam 1&8 rea ard movement of the head 134 and the rack slide 132 the shank wipers 126 to move inwardly from oppos e sides of the and to wipe the cemented m gins of the upper over the molded shank of the heel breast and the shank portions of the shoe.

It will be noted particularly that the pressure to which the hollow pad 74 is subiecte eifective in causing the pad to bulge throughout its entire upper and heel breast surface, imparting full pressure to the sole in these locations.

As the shaft 40 continues to rotate, the cam 160 wings the cam lever 157 reversely, separating he shank clamping pads 150 from the work. The cam 64 then becom s eifective to lower the jack and release the pressure against the heel wipers. Thereupon, the can] 148 becomes effecti e to permit forward movement of the rack slide 132, unlocking the arm 110 and outwardly moving the side wipers. The pressure upon the pad '74 has meanwhile been released, and finally the arm 110 is permitted to return to its elevated position and the machine is automatically stopped in its position, leaving the partially fini hed shoe free to be removed from the form as. After the shoe has thus been operated upon it is contemplated that the forepart portion of the upper will preferably be shaped and fastened to the solo by the use of a machine shown in my copending application, Serial No. 634,317, filed on Sept. 22, 1932.
