APPARATUS FOR USE IN ATTAGI-IING SOLES TO THE LASTED UPPER-S OF BOOTS AND SHOES.

Application filed January 21, 1925, Serial No. 3,749, and in Great Britain January 29, 1924.

It has long ago been proposed to attach the soles of shoes (which te m is intended to include boots) to the lasted uppers by means of an adhesive, the most successful method be- 5 ing to roughen the parts that are to be thus secured, then apply an adhesive such as celluloid cementand allow this to dry, and when the parts are to be secured a further layer of cement is applied and then the parts are pressed together and maintained under pressure for sometime until the cement has set sufliciently, after which the shoe is exposed to the air to allow any remaining solvent to evaporate. V

This method has comparatively recently been eXtensively employed for securing insoles and thin insoles in position, although tests go to show that even fairly thick outsoles can thus be quite securely attached, it being generally or sometimes preferable first to securean-insole to the upper as described and after this has firmly set the outsole is at tached, the parts being roughened (and if desired a suitable filling applied in the usual way), coated with adhesive or cement, allowed to dry and the final coating of cement then applied and the parts subjected to pressure as already described.

The object of this invention is to provide a simple andcheap apparatus (that is more especially intended for use by boot repairers and such boot makers as have a comparatively verylimited. trade or output) whereby the pressing togetherof the sole and upper may effectively and reasonably expeditiously 'be effected. I A simple constructional form of my invention to which I do not, however. limitthe f scope of my invention is illustrated diagrammatically in the accompanying drawing wherein Fig. 1 is a side elevation. Fig. 2 is a plan view, the cross-head to be referred to being omitted. Fig. 3 is an enlarged sectional view on the line 33, Fig. 2, showing the'manner in which the cushion conforms on th': t -e es of the side walls of the a w by a. frame 33 rubber layer serving to make the cushion watertight and the leather serving to protect the rubber from injury and preventing the solvent of the cement from coming in contact therewith. The metal frame D will be secured to the container A by screws or otherwise as may be found desirable.

E indicates a shoe (or boot). placed sole down on the cushion, said shoe having been prepared in the manner already described.

The container A is provided at one end with a sort of funnel F having a cock or valve G and an air vent H having a cock 01' valve J.

Before the workman begins to attach the soles to the shoes or boots. he will turn up the apparatus on edge and will open the cooks G and J and pour water into the container. hen this is full he will shut off the cocks and place the apparatus into normal position.

The shoe is placed. on the cushion and is then pressed firmly down on the flexible cushionas will be described. If the cushion is full of water, the flexible cover may not, to the desirable extent, yield to cause it to wrap to an extent around the edge of the sole and upper. In such event the workman will open the cock J to permit a desirable amount of water to escape as he presses the shoe down on the cushion. He will then shut off the cock and proceed with the work.

For pressing the shoe down on the cushion we provide a sort of bridge-piece K which, for the sake of strength, and also to allow the upper instep portion of the shoe to enter, has an inverted U sectioned shape, which bridge-piece engages the shoe at about the forepart and the last at the heel portion..

The bridge-piece is pressed down by a screw M and hand wheel N, the screw M passing through the screw threaded boss 0 of a cross-head R. The crosshead R- is supported by rods P screwed to the frame of the apparatus or to lugs Q thereon, nuts S serving to maintain the cross-head in desired position on said rods. I V

The bridge-piece K will be providedwith a cushion or pad T to protect the shoe against damage and the free end U of the screw M will engage one or other of recesses "i on the hridge=piece K to hold this adjusted position.

I may be so shaped that the flexible cover fits into the shank of the boot or shoe as shown best in Fig 3.

Such a shape is specially adapted for halfsoling a shoe. It will be noted that the top edges 9 of two opposed sides of the rigid container are directed upwardly slightly at one end as shown at 10 and that the end 15 of the container has the vertical face 12 to which the edge of the flexible cover is secured. The clamping member D is shaped at one end to conform to this shape otthe container, said clamping member having the angular portions 13 which overlie the high portions 10 of the sides of thecontainer and also having on each side at said end the depending vertical portions 1st which are connected. by' the transverse portion 18, both the portions 1 1 and 18 having vertical faces corresponding to the face 12. The inrginal portions of the tle'zzible cover extend up around the upwardly-direeted face 10 and are clamped thereto by the angular portions 13 of the clamping member D and the end of the flexible coveris dir cted downwardly and is clamped against the vertical wall 12 by the

vertical portions

14, 18 ot' the clamping member D. At one end of the cushion or pad, therefore, the flexible cover extends upwardly and then is bent forwardly into the horizontal portion that is clamped to the horizontal edges 9.

The vertical dimension of the end 15 of the container and of the cross portion 18 of the clamping member is such that the upper ec ges of these parts lie below the upwardlycurved portion 10 and as a result the flexible cover will extend upwardly above the top of the side 15 and cross portion 18 thus providing a hydraulic cushion with a flexible corner 16.

lVhen a half-sole onlyis to be applied to ;he shoe said shoe will be positioned on the cushion or pad with the heel resting against the vertical portion 18 of the clamping meinher and with the flexible corner 16 of the cushion or pad beneath the waist or shank 17 01' the shoe. When pressure is applied to the shoe through the medium of the screw M the flexible cover or pad will conform to the shape of the waist or shank 17 of the shoe and will apply as great pressure .to said shank as to the bottom of the sole. In halfsoling a shoe the rear end of the half-sole usually terminates in the shank portion of the shoe and this construction enables the pressure to be applied evenly throu hout the bottom of the sole and the shank oi the shoe even though the shoe has a high waist or shank.

This feature of making the cushion device so thatat one end the flexible cover or pad extends above the rigid end 15 of the container and above the corresponding portion 18 ofthe clamping member is an important feature of the invention as it provides a hyclrhiulic pad which is peculiarly adapted for cein'enting half-soles on shoes without removing the heel because by placing the shoe in the position shown in the drawings the heel is located entirely outside of the cushion or pad and the flexible corner 16 of the cover or pad provides for applying the pressure uniformly on the bottom and the shank of the shoe. g

A shoe with a high heel or deep waist can be operated on equally well as a shoe with a low heel such as shown in the drawing because" the heel is located entirely outside of the pad. I

If a comparatively thick half-sole that extends a little distance beyond the edge of the last is being applied it will be quite "all right usually to let the cushion remain full of liquid. If, however, the sole is comparatively thin-for instance of the kind used in turn shoe worl:it will be generally desirable, after the shoehas been pressed down on the cushion as stated, to open the vent and by this means (the pressure of the shoe on the cushion) some of the liquid within the cushion will be expelled and, if the pressure on the shoe be more or less n'iaintained, the shoe will more or less sink into the cushion or, in other words, the cushion will lap over and in a measure wrap around the edge of the sole and the last. Of course, so soon as the shoe has been embedded to the desired sufficient extent in the cushion, the valve of the vent is closed and the full pressure applied to the shoe. By this means the cojn'iparatively thin edge of the sole is pressed firmly against the upper even though this is not quite fiat. In the case of a thick sole its edge would not yield as statedfand therefore a comparatively stiff and unyielding cushion may be suitable;

li hei'i a complete or whole sole is "to be ap plied or if for-any other reasonit should be desirable to subject the waist as Well as the :torepart oi the sole to pressure, it will [be desirable to shape the flexible cover at the appropriate part so that it, at any rate approliiinately, fits into the waist this means an equal pressure is applied to all tlieparts at any rate almost simultaneously.

There will he usually two cushions as described carried side by side s'e that-a pair of shoes i'n'ay be dealt with. v

l1 the apparatus is'intended only for half.- soling the contziin'er may be made comparatively short so that the waist of the shoe will rest on the edge '01 one end of the container. I i

If a very elastic pressure is required, say at the sides of the shoes, we may fill the cushions less than full with liquid so that there will be an upper layer of air when the cushion is. in use, and instead of fixing a flexible cover to the rigid container We may ill) employ a flexible bag also made of rubber and an external surface of leather (and provided with a vent or funnel) which is simply laid into the container.

lVhat I claim is:

1. In a device for half-soling shoes, a hydraulic pad comprising a container having rigid sides and bottom and a flexible top secured at its marginal portions to said sides, two opposed sides being higher adjacent one end of the pad than the intermediate side, whereby the flexible top extends upwardly from the upper edge of the intermediate side and thereby forms a pad with a flexible corner adapted to conform to the shape of the shank portion of the sole of a shoe which is placed on the pad with the heel of the shoe outside the pad and against said intermediate side, and means to press the shoe against the pad.

2. In a device for repairing shoes a hydraulic pad having rigid sides and aflexible shoe supporting face secured at its marginal edges to said rigid sides, the rigid side at one end of the pad being lower than portions of the adjacent sides near said end, said flexible face extending upwardly from said lower side to approximately the level of said portions of the adjacent sides thereby to form a free flexible corner adapted to engage the shank portion of the sole of a" shoe which is placed on the pad with the heel of the shoe outside the pad and against said lower side and means to press the shoe against the pad.

8. In a device for repairing shoes, a chamber filled with liquid and having sides with rigid edge portions and a flexible shoe supporting member secured to said rigid edges, the rigid edge of one side of the chamber being below adjacent portions of the rigid edges of the adjacent sides thereof, the portion of the flexible shoe supporting member above the lower rigid edge forming a free flexible corner adapted to engage the shank portion of the sole of a shoe which is placed on the pad with the heel of the shoe outside the pad and against said lower side, and means to press the shoe against the pad.

4. In an apparatus of the class described in combination, a pad to receive a shoe and conform to a part of the shoe by pressure thereon, said pad comprising a chamber having sides with rigid edge portions and a flexible shoe supporting member secured to said edges, the rigid edge of one side of the chamber being below adjacent portions of the edges of adjacent sides thereof, the portion of the flexible shoe supporting member above the lower edge forming a free flexible corner adapted to engage the shank portion of the sole of a shoe which is placed thereon, and means to increase the extent of conformation of the pad to the shoe during the operation on the shoe without increasing the pressure of the pad on the shoe.

5. In an apparatus of the class described, in combination, a pad to receive a shoe and conform to a part of the shoe by pressure thereon, comprising a chamber having sides with rigid edge portions and a flexible shoe supporting member secured to said edges, the rigid edge of one side of the chamber being below adjacent portions of the edges of adjacent sides thereof, the portion of the flexible shoe supporting member above the lower edge forming a free flexible corner adapted to engage the shank portion of the sole of a shoe which is placed thereon, and means including fluid inlet and outlet valves to increase the extent of the conformation of the pad to the shoe during the operation 011 the shoe without increasing the pressure of the pad on the shoe.

6. In an apparatus of the class described in combination, a pad to receive a shoe and conform to a part of the shoe by pressure thereon, comprising a chamber having sides with rigid edge portions and a flexible shoe supporting member secured to said edges, the rigid edge of one side of the chamber being below adjacent portions of the edges of adjacent sides thereof, the portion of the flexible shoe supporting member above the lower edge forming a free flexible corner adapted to engage the shank portion of the sole of a shoe which is placed thereon, and a valved funnel and an air vent connected to' one side of the pad.
