2 Claims. -1

This invention relates to machines for operating on shoes, this application being a division of an earlier application for Letters Patent for im-- provements in Lasting Machines, Serial No. 152,876, filed on March 30, 1950, now United States Letters Patent No. 2,651,063, granted on September 8, 1953. The invention is herein shown as applied to a lasting machine the construction of which is in many respects such as found in bed-lasting machines of a well-known type exemplified by the disclosure of United States Letters Patent No. 1,018,477, grantedon February 27, 1912, on an application of Matthias Brock, but it will be understood that it is not limited to this illustrative embodiment.

An object of the invention is to provide improved means for clamping a shoe around an end portion thereof, the construction shown comprising a heel band and novel means for applying it around the heel and of the shoe to assist in controlling the shoe during the lasting of its As herein illustrated, the shoe is mounted on a shoe support including a last pin which engages the heel end of the last in the usual spindle hole, and after it has been so mounted the heel band is moved bodily length- Wise of the shoe into engagement with its heelend face and is thereafter closed inwardly at the opposite sides of the shoe. For thus moving the heel band bodily there is provided a support secured to the intermediate portion of the band and mounted for movement lengthwise of the shoe, and slidingly movable lengthwise of the shoe in this support isa member for closing the first through a spring to move the support and,

thus to impart the bodily movement to the band, after which the spring yields and the member moves relatively to the support to close'the band.

The invention will now be more particularly described with reference to the accompanying drawings and thereafter pointed out in the claims.

In the drawings,

Fig. 1 is a view in front elevation of the machine to which the invention is herein shown as applied, with parts broken away;

Fig. -2 is a plan view of the right-hand portion of the machine, with parts broken away, and

Fig. 3 is a section on the lineIH--III of Fig. 2.

As disclosed in application Serial No. 152,876, now Letters Patent 2,651,063 and of which this application is a division, the machineis provided with means for lasting the toe end of the shoe, which means it is unnecessary to describe for an understanding of the present invention.

The machine includes a frame 2 on which is pivotally mounted at 4 for horizontal forward and rearward swinging movements a casting 6 the right-hand portion of which is supported on the frame but is broken away inFig. 1, this casting corresponding to the part 3 shown in the above-mentioned Letters Patent No. 1,018,477. The casting 6 has mounted thereon means about to be described for supporting and controlling the heel end of the shoe in the toe-lasting operation, but Without any heel-lasting means, and it will be understood that, similarly to the disclosure of the above-mentioned Letters Patent No. 1,018,477, it is swung rearwardly to an adjustably predetermined position when the machine is to operate on a right shoe and forwardly to the appropriate position when the machine is to operate on a-leftshoe.

Secured on the casting 6 in fixed relation thereto is another casting 8 which, through means hereinafter described, supports a heel band II] for embracing and clamping the shoe about its heel end. The shoe is supported at its heel end on a jack 12 including a U shaped member I3 one of the arms of which has a horizontal extension 14 guided for movements in directions lengthwise of the shoe in the casting 6. This extension has on its upper face rack teeth 16 engaged by a pinion 18 which is rotatable on the casting 8 and is turned by a hand.

lever 20 to effect a preliminary adjustment of the jack relatively to the heel band ID. A springpressed pin22 on the hand lever is arranged to enter any one of a plurality of holes 24 in the casting 8 to retain the jack in adjusted position. The adjustment is preferably such that when the shoe is first mounted on the jack there is substantial clearance between its heel end face and the intermediate portion of the open band it, as illustrated in Fig. 2. The left-hand arm 'of the U-shaped member 13 has mounted therein an upwardly extending post '26 which, -similarly to the post 50 shown in Letters Patent No. 1,373,482, granted on April 5, 1921 on an application of Matthias Brock, can tip yieldingly in directions widthwise of the shoe against 'the resistance of opposed leaf springs "on the "member [3, one of these springs being shown at 28. Pivotally mounted ona pi'n 30ih't'h'e post 26to tip in directions withwise of'the shoerelatively to 'the post is a block 32 which isyieldingly controlledat its lower end by a spring-pressed pin "(not shown) acting similarly to the member 1'9 shown in Letters Patent No. 1,128,303, grantedon February 16, 1915 man-application or J. 'Faiiss'e. In the construction herein shown there is 'pivotally mounted on the block 32 to swing about a pin 34 extending widthwise of the shoe a block 36 provided with an upwardly extending last pin 38 arranged to enter the usual spindle hole in the heel end of the last. A spring 40 connected to the post 26 and the block 36 tends to swing the block and the last pin 38 in a clockwise direction as viewed in Fig. 1 and holds them initially in positions determined by a stop screw 42 which is threaded in the block 36 and is arranged to bear against the upper end of the post 26.

The intermediate portion of the heel band it is secured to a holder 44 (Fig. 2) having a stem 43 held by a setscrew 43 in a yoke-shaped member 50. This member is secured indirectly to a plate 52 (Fig. 3) guided for movements in directions lengthwise of the shoe in the casting 8. Secured by screws 64 to the plate 52 to move therewith is a block 56, and in this block is slidingly mounted a rod 58. Pivotally mounted on a stud 60 on the left-hand end of the rod 58 is a crossbar 62 the opposite ends of which are connected by links 64 to slide bars 66. These slide bars are guided in recesses in the opposite ends of the yoke member 50 and at their left-hand ends are pivotally connected by pins 83 to levers 70 in locations between the ends of the levers. The inner ends of the levers are pivotally connected by pins 72 to blocks I l fast on the opposite sides of the heel band I and their outer ends are connected to springs 76 which tend to swing their inner ends in directions toward the toe end of the shoe. Formed on the slide bars 06 are cam faces 28 arranged to be engaged by abutment faces 80 on the yoke member 50 to close the heel band inwardly against the sides of the shoe in response to lengthwise movements of the slide bars relatively to the yoke member, in which operation the levers are swung about the pins 63 against the resistance of the springs E6. Such lengthwise movements of the slide bars are eifected by moving the rod 53 toward the left relatively to the block 56 and the plate 52 to which the yoke member 50 is secured. Prior to this operation, however, the heel band is moved bodily lengthwise of the shoe to seat it firmly against the heel-end face of the shoe by moving the block 56 with the rod 58. For this purpose there is mounted on the rod, between the block 53 and a member 02 fast on the right-hand end of the rod, a compression spring 82. The member 82 acts through the spring 83 thus to move the block 56 until further bodily movement of the heel band is prevented by the shoe, after which the spring yields and further movement of the member 82 serves to move the rod 53 relatively to the block 56 to close the heel band. To operate the member 02 it has extending through it a rod 86 (Figs. 1 and 2) on which is mounted a compression spring 60 located between the member 82 and a plate 90 confined on the right-hand end of the rod by a nut 92. A head 94 formed on the left-hand end of the rod engages the member 02 to limit expansion of the spring. Portions of the rod and the spring are broken away in Figs. 1 and 2. The head 04 on the rod is connected by a link 66 to the upper end of a lever 38 which is pivotally mounted on the casting 8 and has a downwardly extending arm I00 engaged by one end of a push rod I02. The other end of this push rod is engaged and operated by a lever I04 pivotally mounted on a pin I06 on the casting 6. This lever is a power-operated lever, but the mechanism, including a cam, for operating it, is not herein shown, since it is of the same construction as mechanism provided heretofore in machines of the type shown in Letters Patent No. 1,018,477 for closing the heel band, as disclosed especially in Letters Patent No. 1,417,493, granted on May 30, 1922 on an application of Matthias Brock. The lever I04 corresponds to the lever I22 in the last-mentioned Letters Patent. It will be understood that the spring 88 is stronger than the spring 84 and may yield only in response to resistance of the shoe to the closing of the heel band. The lever 98 is operated against the resistance of a return spring I08 which assists in returning parts operated by the lever to their initial positions. That is, the member 82 and the rod 56 are returned by the head 94 of the rod 86, and the block 56 is returned by engagement of the crossbar 62 therewith.

The toe end of the shoe is supported on a toe rest I I0 mounted on the upper end of a vertically movable rod II2, this rod being supported at its lower end on a member II4 corresponding to the member 22 shown in Letters Patent No. 1,018,477. By means of a power-operated cam (not shown), which corresponds to the cam I30 shown in Letters Patent No. 1,417,493, the member I I4 is moved upwardly to elevate the toe rest a predetermined distance in time relation to the operation of the heel band I0. In this manner the toe rest cooperates with the heel band in jacking the shoe and in positioning the toe end of the shoe heightwise in proper relation to the toe-lasting means. It will be understood that as the parts are shown in Fig. 1 the jacking of the shoe and the operation of the heel band have not as yet taken place.

When the heel band I0 is moved bodily as hereinbefore described to seat it against the heelend face of the shoe it imparts a short lengthwise movement to the shoe to cramp the last pin 38 in the spindle hole in the last, the last pin swinging about the pin 34. This causes the last pin to assist in holding the shoe firmly against any upward movement of its toe end in the toelasting operation. To afiord additional insurance against any displacement of the shoe lengthwise in a heelward direction in the toelasting operation, mechanism is provided for positively locking the heel band against retractive movement. For this purpose a pair of pawls H6 (Figs. 2 and 3) arranged in staggered relation are pivotally mounted on a pin I I8 supported on a block I20 which is secured to a top plate I22 on the casting 3. A spring I24 tends to swing the pawls downwardly, and for the purpose in view they are arranged to engage teeth I26 formed on a plate I28 which is secured by the screws 54 to the plate 52. Each pawl is provided with a roll I30 arranged to rest on the top face of a horizontal bar I32 slidingly movable in a guideway in the block I20 and secured at its righthand end to the previously mentioned plate which is carried by the rod 86. By engagement of the top face of the bar I32 with the rolls I30 the pawls are held initially upraised, as shown in Fig. 3, but as the bar is moved toward the left in the operation of applying the heel band to the shoe inclined faces I34 on the bar arrive in positions under the rolls I30 and permit the pawls to be moved downwardly into engagement with the teeth I26. It will be understood that in the return of the parts to starting positions the pawls are disengaged from the teeth by the inclined faces I34 to release the block 56.
