4 Claims.

This invention has for its object to provide a novel attachment which can be readily applied to an ordinary beating-out machine such as is used in connection with the making of a McKay- 5 sewed shoe and which converts said machine into one that is well adapted for use in cementing soles to shoes.

In cementing soles to shoes it is highly desirable to apply a substantially even pressure to the sole throughout its entire extent so as to produce proper adhesion between the sole and the shoe bottom at all points.

The beating-out machine which is commonly used in making McKay-sewed shoes comprises a jack or last on which the shoe is placed and a die member having the proper contour and shape to lit the outside of the sole together with means for pressing the die member against the bottom of the sole with a heavy pressure. In these beating-out machines both the last or jack which is inserted into the shoe and the die member are made of metal and, therefore, the faces between which the sole is pressed are rigid and unyielding. A press which has a rigid and unyielding face to engage the sole does not make a satisfactory press for cementing soles to shoes because best results can be secured if the die member which applies pressure to the outside of the sole has a yielding face.

Accordingly I have provided a novel detachable pad or face member of yielding material which can be easily applied to the die of an ordinary beating-out machine and which converts it into a machine which can be successfully used in cementing soles to shoes.

In order to give an understanding of the invention I have illustrated in the drawing a selected embodiment thereof which will now be described after which the novel features will be pointed out in the appended claims.

Fig. 1 is a fragmentary View partly in section illustrating the die and jack of a beating-out machine with my improvements applied thereto;

Fig'.` 2 is a perspective view of the detachable pad.

Since the present invention relates particularly to an attachment to be applied to the die of the beating-out machine I have not thought it necessary to illustrate a complete machine but have shown only a sufficient part thereof to enable the present invention to be understood.

In the drawing 1 indicates the jack of a beatingout machine and 2 is the die member adapted to apply pressure to the sole of the shoe. This jack or last is preferably made of iron and is intended to be placed in the shoe to be treated, which shoe is indicated at 3. IIhe jack is mounted on a suitable portion 4 of the machinegand the die 2 is carried by another portion 5 of the machine. In the complete machine means are provided for j@ moving the jack and the die toward each other to apply pressure to the sole of the shoe.

The feature of the present invention relates to a pad 6 of suitable resilient material which can be detachably applied to the operative face 'I of C5 the die member 2 thereby to provide said die member with a yielding or resilient face which is desirable in cementing'soles to shoes.

The pad member 6 can conveniently be made of krubber or any other material which has yielding 7g and resilient qualities. In the preferred form of my invention this pad comprises a body portion S of rubber or other resilient material and a facing 9, preferably of leather, said facing and body portionbeing adhesively united and thus fg making a laminated pad. The facing 9 is provided at each side with

tabs

10, 11 and 12 which form part of the means for attaching the pad to the die member 2.l

In the construction herein shown the

tabs

10, 11 and 12 at each side of the pad are connected by a metal strip 13, each strip being preferably connected to the central tab by means of a wire or other connection 14 and being connected to the front and rear tabs l0 and 12 by a spring connection 15. rl`he front ends of the two metal strips 13 are connected by an elastic connection 16 and the rear ends of said metal strips are connected by another elastic connection 17. These elastic connections may conveniently be in the t form of coiled springs but they may be made in any desirable way so long as they have the necessary elastic quality.

The pad can be readily applied to the die 2 by placing the

elastic connections

16 and 17 around u the ends of the die as shown in Fig. 1. The dies 2 of these beating-out machines are universally made with front and rear ends 18 and 19 which incline upwardly and inwardly. The elastic connections are of such length that when the pad 6 is applied to the die 2 these connections will be stretched somewhat and their resiliency will cause them to hug the ends 18 and 19 of the die thereby holding the pad securely in place. The downwardly and outwardly inclined ends of the die co-operate with the

elastic connections

16 and 17 to ensurethat the pad is properly held on the die.

With the pad thus applied to the die the operation of cementing a* sole tol a shoe is as follows.

'los

After the shoe has been completed to the point where the sole 2O is to be attached then a suitable adhesive or cement is applied to the shoe bottom and the sole 20, and the sole is laid on the shoe bottom in the correct position. The cement Which is used is of such a character that it will hold the sole in place While the shoe is being applied to the last. The shoe with the sole thus applied thereto is then placed over the last or jack 1 as shown in Fig. l and the beating-out machine is then operated to cause the sole to be pressed between the jack l and the die 2.

The resilient pad 6 gives as the pressure is applied and if the sole should be thicker in one place than another or if the metal faces of the jack and the die should not be in absolute parallelism, the yielding qualities of the pad 6 will permit it to yield or give so that the pressure will be applied evenly throughout the area of the sole and a good cementing job Will result.

I claim.

1. A sole-cementing attachment for beatingout machines comprising a pad of resilient material and means for detachably applying said pad to the operative face of the die member of a beating-out machine.

2. A sole-cementing attachment for beatingout machines comprising a pad of resilient material having tabs at each side at both the fore part and heel part, a resilient connection connecting the tabs at the fore part and another resilient connection connecting the tabs atthe rear part, said resilient connections adapted to embrace the ends of the die when the pad is applied to the operative face thereof, thereby to hold the pad in position.

3. A machine for cementing soles to shoes comprising a jack member on Which the shoermay be placed, a die member for applying pressure to the sole of the shoe, said jack and die member being movable toward each other to apply such pressure, and a pad of resilient material detachably applied to the face of the die member.

4. A sole-cementing attachment for beatingout machines comprising a pad of resilient material having a shape to be applied to the operative face of the die of a beating-out machine, said pad having a plurality of tabs extending from each side thereof, a metal strip connecting the tabs on each side of the pad, and elastic connections connecting the front and rear ends of the metal strips and adapted to encircle the iront and rear ends of the die thereby to hold the pad in position.
