To all rwhom t may concern.'

Be it known that I, CONSTANT WAssILL, citizen of the Goverment of Russia, residing at Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Heel- Clamps, of which the following is a specication.

The object of this invention is to provide a new and improved heel clamp for clamping and holding a heel in position on the solel of the shoe while the glue, which is intended to hold it there, is setting and hardening.

This and other objects vof the invention will be illustrated in the drawings, described in the specification and pointed out in the claims at the end thereof.

In the drawings:

Figure 1 is a front elevation of the clamp.

Fig. 2 is a side elevation of the clamp, showing the shoe and heelin position.

Fig. 3 is a section on the line 3"-3x of Fig. l.

Fig. 4 is a horizontal section on the line 4"-4x of Figs. 1 and 2.

Fig. 5 is a modified form of the clamp shown in side elevation. F Fig-6 is a section on the line GFI-6X of n the drawings, like reference numerals indicate like parts.

In the drawings, reference numeral 1 indicates the bench or table on which1 the clamp is mounted and 2 indicates the floor. Reference numerals and 4 indicate pedestals fastened to the bench which are hollow and through them pass the rods 5 and 6. These rods are connected to the'yoke 7 at the top and to the yoke 8 at the-bottom. This yoke is supported by a link 9 which is connected to the treadle 10 which has a foot plate 11 on the forward end thereof and the weight 12 on the rear end thereof. The

spring which presses against the shoulder and holds it down with the pin 21 resting on the top of the bushing and limiting its downward movement. On the bottom of the stem is a ball shaped head 22 which carries a foot 23 having a cup shaped recess in thetop to receive the ball, the upper edge of which recess is loosely battered down to engage vwith the ball. n the bottom is a cir- .cular recess in which is carried a cushion 24, preferably made of leather. The spherical head 22 permits the foot 23 to take any angular position needed to make a proper bearing on the bottom of the heel.

The yoke 7 is recessed horizontally to receive the bracket having a lug 31 thereon, whlch engages with the horizontal recess. This bracket is recessed vertically to re. ceive the bushing 32 which makes threaded engagement therewith and haswthe hexagon head 33 thereon. The bushin vis perforated to receive the stem 34 w ich carries the shoulders or flanges 35 and 36 on the lower end ther^of. Around these flanges is molded a presser foot 37 preferably made of rubber. The stem 34 is surrounded by a spring 38 which bears against the shoulder and draws the stem down with the pin 39 normally resting on top of the bushing.

On the bench between the pedestals'B and -4 is mounted a swinging standard 40 supported by a base 41 on which it is mounted to swing forward through a small angle. This standard has a reduced end 42 adapted to engage with the opening in the last of the shoe and hold it in position thereon.

The shoe properly mounted on the last is place in position on the pedestal with the seat or the heel properly 'coated with glue or cement. The heel is then put in position on the shoe and the operator then presses down on the' treadle 10 drawing down on the link 9 and the rods 5 and 6 and yoke 7. This carries down. the presser foot 23 until it makes contact with the bottom of the heel and the presser foot 37 until it makes contact with the back of the heel, the bracket 30 having previously been adjusted forward or back so that the foot 37 will bear properly on the heel and coperate with the foot 23 to press and hold the heel in position. In so doing the s rings 20 and 38 will be compressed so t at'suitable pressure will be ex'- erted on the heel. The parts are held in this position by a locking device which I will now describe. l

JThe sides of the bars 5 and 6.are recessed on the inner side at the bottom of a series of recesses as indicated at 43 and 44.` On the under side of the table is pivotally mounted a pair of dogs 45 and 46 on the stationary pivots 47 and 48, which pivots are set on the table. The inner ends of the dogs are slotted as indicated at 49 and 50 and are engaged by a pin 51 carried on a sliding handle 52 which handle slides through a bracket 58 between which bracket and the dogs 45 and '46 a spring 54 is held in compression. The expansion of this spring holds the dogs in the whole line position shown in Fig. 4 in engagement with the ratchet teeth on the rods 5 and 6. When it is desired to release the shoe, the handle 52 is drawn forward which swin s the dogs out of engagement with the rods and permits the presser feet to be raised by the weight 12 and the connecting parts..l

In Fig. 5 I have shown a modification of this device which consists of the table 60. having a pedestal 61 thereon which is hollow and in which the rod 62 is mounted to slide. This rod is connected to a link 63 and treadle 64 at the bottom by which it may be drawn down. The forward en d of the treadle is connected to the table by the spring 65 and plate 66, by whichit and the parts connected thereto will be raised and held normally in a raised position.

On top of the rod 62 a yoke or bracket 67 is carried on which are carried the bushings 68 and 69, in which slide the stems 70 and 71. The bushings make threaded engage ment with the bracket 67 and have heXagon heads at the top. The stem 70 has the shoulders 72 and 73 thereon at the bottom on which is molded the presser foot 7 4, preferably made of rubber. The stem 71 has the shoulder 75 on the bottom thereof with the ball end 76 on which is fastened the metal foot 77, the top of which is cup shaped to receive the ball 76 a`nd the upper edge of which is loosely battered down to engage with the ball. The bottom of the foot 77 is finished with a cushion 78 of leather or l other suitable material. Springs 79 and 8O surround the stems 70 and 71 and normally `hold them in their lowest position. On the bench is mounted the swinging standard 81, supported by a base 82 on which it is mounted to swing forward through a small angle. This standard has a reduced end capable of engaging in the last of the shoe and holding it 1n position thereon. When the shoe is 1n position, the operator pushes down on the treadle 64 and forces the feet 74 and 77 down against the heel and presses and clamps the heel in position on the heel seat on the shoeI The rod62 has the ratchet teeth 83 thereon which are engaged by the. dog 84 and is held in position thereby. The dog is withdrawn by the handle 85 which is surrunded by the spring 86 bearing against the shoul- .der 87 on one side and the plate 66 on the other side which holds the dog in engagement with the ratchet. When the dog 84 is withdrawn, the treadle 64 is raised bythe contraction of the spring which raises the link 63 and rod 62 and the presser feet 74 and 77, after which the shoe can be removed from the standard 8l.

The bushing 68- is carried in a block rectangular in cross section as appears in Fig. 6 and the bracket 67 is slotted at 90 to receive it and the block is adjustable forward and-back in the slot and can be clamped in any position thereon by the screw 91.
