TouZZ whom may concern:

Be it known that we, JOHN L. PREO and ISABELLE HENNE, citizens of the United States, residing at 957 Kent Avenue, city of New York, in the county of Kings and State of New York, have jointly invented a new and useful improvement in a Heel-Seat Die, of which the following is a specification.

The object of the invention is to provide a heel-seat die, by means of which, through pressure exerted normally to the heel-seat region of a shoe, a strong heel-seat, perfect in its parts, and perfectly adapted to receive the cup of a wooden or like heel, is formed. The object is further to provide the die with means for protecting the back part of the shoe from distortion under pressure, and for aiding in positioning the shoe as the die de' scends. Other objects and features will become apparent as the specification proceeds. The invention is a division from our application filed October 14:, 1921, Serial No. 507,61i.

In the accompanying drawings forming a part hereof:

Fig. l is a plan view of the die;

Fig. 2 is a side elevation, showing the die in the position in which it is held in the machine;

Fig. 3 is a front end elevation;

Fig. i is a longitudinal section;

Fig. 5 is a view on a smaller scale, partly in transverse vertical section and partly in elevation, illustrating operation, the die be ing about to descend upon the shoe;

Fig. 6 is a similar View showing the die forced down upon the shoe to form the heelseat;

Fig. 7 is a much enlarged fragmentary view corresponding to Fig. 5; and

Fig. 8 is a similar view corresponding to Fig. 6.

The die is formed of an integral block of metal of general oblong form. Upon the bottom face of the block, that is to say the face which is downward in the working arrangement shown in Figs. 5 and 6, is formed a major, interior working face 2, which may be described as concave. This working face 50 smooth and continuous, gently incurved from side to side and at the back, and is so shaped and of such extent as to form the heel-seat proper a of a shoe, which, in the case of a turned shoe is the region of the 5-5 outsole Z within the inturned portion 0 of Divided and this application filed Decem- Serial No. 522,873.

the upper d exposed by edge of the outsole.

Outside of this working face 2, at the sides and back, is a substantially flat marginal working face 3, which is adapted to form a strong, even shoulder (2 upon the inturned portion of the upper, insuring a good junction with the edge of the cup of the heel. Inside this shoulder the heel-seat proper a formed by the face 2 affords a large area of contact.

intervening between the said working faces is a raised rim or ridge 41-, which preferably dies away at the back, substantially to the level of the shoulder-forming face 3, the forward ends of the parts of the ridge also dying away or declining as seen in Figs. 2 and at. The outer sides of the parts of the ridge are laterally inclined, as indicated most clearly at 5, in F ig. 7.

In the ordinary hand method of preparing the seat on a turned shoe, the operator crudely digs out a channel with an awl or other tool, around the region of the heelseat proper, and in so doing frequently destroys some of the stitching f. He then takes a hammer and pounds the area within this channel, continuing with blows variously delivered until he has worked up a rounded formation in as good a fashion as he can accomplish. The result is naturally only approximate; and the shoulder which is obtained by the hand method is likely to be weak. With the die of this invention the heelseat proper and also the shoulder are formed with absolute accuracy and without injury to the stitching, by simple pressure exerted normally to the seat. The wedgelike ridge 4: accomplishes the result usually sought by digging out a channel as described, but without possibility of injury to the shoe, and it has the further effect of tending to spread the heel-seat region, as may be necessary to take the heel.

A. further feature resides in a shield t which rises (or projects downward) from the block at the back of the working face This shield is transversely curved to conform to the back of the shoe, and performs the function of protecting this part of the shoe against distortion under the heavy pressure. It also aids in properly positioning the shoe beneath the die as the die descends. The inner face 7 of the shield longitudinally inclined, as seen in Fig. st.

trimming away the Figs. 5 and 6 illustrate the shoe A on its last 13 mounted upon a suitable support C, and the die is shown secured to a suitable part D forming part of pressure mechanism such as disclosed in our prior application.

l/Vhat is claimed as new is:

1. A heel-seat die comprising a block having a concave interior working face adapted to form the heel-seat proper of a shoe within the inturned portion of the upper, and a shoulder-forming face outside said interior face, the two faces meeting to form a ridge,

2. A heel-seat die comprising a block having a concave interior working face adapted to form the heel-seat proper of a shoe within the inturned portion of the upper, and a shoulder-forming face outside said interior face, the. two faces meeting to form a ridge at opposite sides of the heel-seat, the outer sides of said ridge being inclined.

3. A heel-seat die comprising a block hav ing a concave interior working face adapted to form the heel-seatvproper of a shoe within the inturned portion of the upper, and a shoulder-forming face outside said interior face, the two faces meeting to form a ridge at opposite sides of the heel-seat, the parts of said ridge declining toward the level of the shoulder-forming surface at the ends.

, 4-. A heel-seat die comprising an integral block having a continuous concave lnterlor working face adapted to form the heelseat proper of a shoe within the inturned portion of the upper, and a substantially flat shoulder-forming face extending around said interior face at the sides and rear.

5. A heel-seat die comprising an integral block having a continuous concave interior working face adapted to form the heel-seat proper of a shoe within the inturned portion of the upper, and asubstantially fiat shoultier-forming face extending around said in terior face at the sides and rear, the two faces meeting to form a wedge-like ridge at opposite sides of the heel-seat.

6. A heel-seat die comprising an integral block having a continuous concave interior working face adapted to form the heel-seat proper of a shoe within the inturned portion of the upper, a substantially flat shoulder-forming face extending aroundsaid interior face at th sides and rear, and a transversely curved shield risin from the back of said shoulder-forming face, the inner face of said shield being longitudinally inclined.
