Application filed December 7, 1925,. Serial no. 73,5'43, and in France December a,

The object of my invention is a machine which allows part of the manufacture of shoes with Louis heels to be made with much less handicraftthan has been used up This machine is used before the -...,heels are fixed on the rear "part of the* soles. I will first state how the sole of a shoe with Louis-heels is made. 1) comprises atits rear part-two tongues, the former of which passes inthe finished shoe between the heel and the shoe, the other be- I the tongue 2 which strip 3',

hollowed out portion of *of the machine,

ing folded over and stuck to thefront of. the heel so as to reinforce the means for'securing the heel to theshoe. Up till now all these tongues have been prepared by hand: the rear part of the sole having been cleft previously, cured. to the lower part of the shoe and the tongues 2 and 3 are then cut.

The machine according to'my invention will cut these parts automatically.

Before describing the principal features I willbegin' by showing the operations it has to carry out. These operations are shown diagrammatically on Figs. 2 2 2 -and 3.. 3,, 3 the Figs 2 and 3 being side views, the Figs. 2 and 3 plan views and Figs. 2 and 3 detail views on an enlarged sea e.

The first stage (Fig. 2) consists in cutting is to be placed between the heel and the shoe; this operation consisting in bringing the shoe-4 under a press-knife 5. The. two strips 2' and 3 are shown beforelcutting. The strip 2' is folded over the bearing plate 6, the strip 3 being held forward. The tongue 2 which is obtained by this cutting operation will have the shape of the hollowed out portion 7 of the press-knife 5. In view of the second-stage of the operation (Fig. .2) which consists in cutting the tongue 3 out of the a second press-knife 8 is usedthe shape of the front part of the heel and is much larger'than the hollowed out portion 7 But if the press- 7 of the press-lmife-.5.

I knife were to cut the strip ,3 whilst the tongue 2 is still resting on the plate 6, the

cuttingv would not be properly done as the strip 3 would not lie quite flat. Therefore the plate 6 is replaced by a hollowed out auxiliary plate'lO provided with a supporting plate 6', the shape of the hollowed out portion-of the plate IO-being exactly the shoe for cutting'the This sole 1 (Fig;

:secured to-the frame so the front of the sole is first'se-.

with its sole 1 which has the exact.

other hand is seated, this being provided "by the exact correspondencybetweenthe'tongue 2 andthe hollowed i out portion of. j the auxiliary plate 10.

y The machine for carrying out these open. 55

fit-IOIIS comprises a frame wherein the pressknife is adaptedto -move to and ,fro. A 1110 able vise supporting the shoe allows it to e brought under "the press-knife and allows it to be moved vertically with ref-f erence thereto." Finally, ,a. -bearing' '-plate is as to] support the leather which is being cut. r

In order to carry out the first stage of the operations the machine should comprise a device allowing the position of theshoe with reference to the press-knife'to be ad justed accurately, this adjustment varying with the size of the shoes. This device is constituted preferably by a stop which'has the exact shape of: the rear part of the shoe and is adapted to be moved by a screw'which has only a longitudinal motion producedby a vernier cooperating with a scale'pro- For the second operation the machine is provided with an auxiliary plate the hollowedout'portion of which is the same as that of the press-knife which has served for the first operation; this plate can be secured "to a supporting-plate andholds-thetongue cut during the first operation whilst the second is being formed.

Evidently -if the number of shoes to work upon is great enough, it be ofadvantage to .use two different machines for carry- 'lngout the twooperati'ons; the use of two machines does not widen to a y gree the Scope f he invention. 1

A machine according'to myinventionis describedhereinbelow byway ofv example and shown on appended drawings wherein; Figs. 1, 2 2 ,-2 3., 353., are the explanatorv diagrams described already. I

Figs. 4 and 5'a1-e'\two vertical views per- Fig. 6 is a detail of Fig. 4 at an enlarged scale, Figure 4 showing themachine'ready for tle first operation and Figure 6for the secon pendicularone-with referenc'e'to theoth'er;, i

In the frame 12 ashaft 13 is adapted to rotate. It bears the control lever 14 and the eccentric parts 15 which actuate through the small red 16 a piston 17 which bears t e ress knife'5 or 8 shown on Figs. 2 and 3.

he piston 17 is uided in the sleeve 18. Its deflectiontowards the right or the left is prevented by a stud (not shown) sliding in a groove provided in the frame 12.

The frame shows a slide 19 wherein the sole 20 of the vise which supports the shoe is adapted to move. To this'sole is secured a threaded screw 21 cooperating witli the threaded sleeve 22 which allows the sup ort 23 of the shoe to be raised or lowered. This support is inde endent of the sleeve and simply rests on it so as not to rotate along with it. The movement of the sole is stopped by a stop plate 24. It can be secured in its correct position b means of a lever 25, the eccentric pivot 0 which bears against a blocking part .28. 5

The accuracy of theposition of the shoe for the first operation is ensured by the stop 29 which is hollowed out so as to show the exact shape of the seat or rear art of the shoe. This stop is securedto t e end of a threaded rod 30 which passes through a controlling nut 31 held by the frame so as to be unable to move longitudinally along the rod 30. The latter on the other hand, is provided with a rear part 32 having a square section adapted to move in a square hole, whereby the threaded rod 30 is prevented from rotating. By actuating the nut 31 the stop 29 is caused to move forward or rearward. A vernier late 33 is secured to the rod 30 and moves in front of the stationary scale 34'disposed on the frame, thereby enabling a correct placing of the stop according to the size of the shoe. For the second 'operation the-auxiliary plate 10 gFig. 6) is secured on a sup orting s stated hereinbefore this ollowe out plate allows the accurate placing of the shoe with reference to the press-knife.

late.-

eeann The form of execution which has been described has only been given by way of example and any constructional modifications can be brought to it without extending the scope of the invention. Thus for instance the plate 6 could instead of being secured to the frame-of the machine be secured to the press-knife holder with the interposition of springs. I

Evidently if as already stated, two machines are used, theone intended for the second operation need not be provided with an adjustable stop 29 because in this case the shoe can be accurately put in place by means of the tongue punched during th first operation.

What I claim is:

1. In a heel seat fitting machine, a frame, a shoe support carried-thereby, a press knife mounted in the frame for movement towards and from a shoe on said su port, a bearing plate carried by the frame or sup orting a flap onthe rear portion of the so e of the supported shoe which has been previously cut in such a manner as to adapt it to be inserted between the shoe and a heel to be attached thereto, and a second plate secured to the bearing plate for supporting a second flap on the rear portion of said sole and having a hollowed out portion the side edges of which correspond to the sideedges of the first mentioned reviously cut flap.

2. Ina machine as c aimed in claim 1, the combination of'a stop adapted to fit against the seat of the shoe, a screw secured to said stop, a nut cooperating with the screw and ada ted to move it longitudinally together witi the stop, means whereby the screw is prevented from rotating, means whereby the nut is prevented from moving longitudinally, a vernier borne by the screw, and a graduation borne by the frame in front of said "ernier.

In testimony whereof I have aiiixed my signature. 1
