SHOEMAKERS LAST.

Application led September 15, 1926. Serial No. 135,526.

This invention relates to the re-soling of shoes and particularly to a noveLform of shoe last which is useful in this art.

This application is a continuation in part 'of my application entitled Method of and appara-tus for cementing soles to shoes, Serial No. 54,986, filed September 8, 1925. v

As fully disclosed in my application supra, it is general practice to attach new soles to shoes either by sewing or by nailing. It is well known that sewing or nailing of a sole to a shoe damages the welt and inner sole thereof. My invention mentioned above provided apparatus by means of which new 5 soles may be applied to shoes by cementing them in place. In this method of cementing soles to the bottom of shoes itis very necessary that pressure be evenly placed on the entire sole of the shoe so that a complete cementing at all portions will be effected.

It is therefore necessary that the shoe last or form, which is inserted into the` shoe when the sole is being applied, be so designed that the extremities thereof extend to the edges of the interior of the shoev so that a pressure may be applied to the edges of the sole as well as to the central part thereof.

It is an object of this invention to provide a shoe last by means of which a pressure may be applied to the entire bottom sole of the shoe.

Another object of the invention is to provide a shoe last which is expansible and which has an extending rim so that pressure may be applied to the extremities of the bottom of the shoe and the sole.

In making shoes a filler is placed in a thin space which exists ,between the inner sole and the sole of the shoe. When the shoe is worn the central part of the bottom and against the sole, it is necessary that the shoe last be so formed as to have a convex' or bulging portion which will fit into the hollow of the bottom of the shoe and so that a pressure will be exerted on the central part of the bottom of the shoe as well -as on the extremities.

tends to exert great pressure on the arch ofA the shoe, breaking it down and spoiling the shape thereof.

It is an objectl of my invention to provide a combination last and heel-piece which may be used when applying full soles to shoes and which will not break down the arch.

Other objects and advantages of the invention will be made evident hereinafter.

Referring to the drawings which are for illustrative purposes only,

Fig. 1 is a vertical section through the invention showing it placed in a shoe.

Fig. 2 is a section taken on the line 2- of Fig. 1.

Fig. 3 is a section taken on the line 3-3 of Fig. 1.

Fig. 4 is a section taken on the line 4-4 of Fig. 1.

Fig. 5 is a fragmentary section of the toe of the last taken substantially as indicated by the arrow 5 of Fig. 1.

Fig. '6 is a view illustrating the manner in which the invention and the shoe are placed in a1 pressure applying device.

Fig. 7 is an enlarged fragmentary view showing clearly the manner in which the lzlilst fits the contour ofthe bottom of the s oe.

Fig. 8 is a small view illustrating the invention when used on exceptionally long shoes.

Referring to Figs. 1, 2 and 3, the shoe last of my invention comprises a pair of complementary sections 11, the sections 11 being right and left hand as shown. Each section 11 is provided with a foot port-ion 12 which is recessed at 13 tolmake it lighter. The foot portion 12 of each section 11 forms a body which is adapted to extend into the forward part of a shoe 14. Extended upward and rearward from the back part of each foot portion 12 is a shank member 16, and extending forwardly above the shoe 14 from each shank member 16 is an arm member 17 which has a flat upper face 18. The inner face of each section 11 is substantially YHat so that it may fitagainst the face of the other of the sections 11.

Formed in each shank member 16 on the inner face thereof is a channel 21 which is connected to the upper end of the shank by means of an opening 22. Placed in the upper ends of the channels 21 is a nut 23 having laterally extending arms 24. Each arm 24 extends outward into an opening 25 formed near the upper end of each shank 16. Extending into the channels 21 through the openings 22 is a threaded shaft 27 which is i screwed through the nut 23. The upper end of the threaded shaft 27 is provided with a hand-wheel 28, by means of which it may be rotated so as to be advanced up or down. The lower end of the threaded shaft 2T is provided with a head 29 which operates in the channels 21.

The toe ends of the foot portions 12 are attached together by a tie plate 32 which is pivotally attached to each foot portion 12 by a suitable pivot pin 33. The forward ends of the foot portions 12 are countersunk as indicated at 34 for receiving the tie plate 32.

Extended from the upper ends of the Shanks 16 in a rearward direction are ears 36 through which a connector in the forni of a cotter pin 37 is extended. (See Fig. 4.) This cotter pin 37 holds the upper ends of the sections 11 together.

The head 29 when it is moved downward in the channels 21 forces the rearward parts of the` forward portions 12 outward in opposite directions, these portions pivoting on the pivot pins 33. As noted in Fig. 5, the forward ends of the faces 20 of the sections 11 are curved outward at 39 so that a relatlve swinging action may take place between the two members.

Referring to Fig. 3, the lower face of each foot portion 12 is provided with a convex o1 bulged face 41. The extremities of the foot portions 12 are provided with outwardly extending rims 42 having flat lower faces 43. These rims 42 extend materially outward from the 'main part of the foot portions 12. The rearward parts of the foot portions 12 are provided with curved lower faces 46 which fit the contour of the forward part of the arch 47 of the shoe 14.

Referring to Fig. 1, I provide a heel-piece 48 which is ada ted for use n conjunction with the last wien a full sole is being applied to the shoe 14. The heel-piece 48 has a back strip 49 which is curved to fit the shape of the back 50 of the shoe. Extending forwardly from the back strip 49 is a central web 51 having an arched lower face 52. The forward part of the web 48 is a diagonal front strip 54, the strip slantinof downward and forward from the upper end thereof. A front face 55 of the front strip Lezsaaee 54 is adapted to be engaged by the lugs 36 formed near the upper ends of the shanks 16. The heel-piece engages the bottom of the shoe only at the point 57 and the point 58 as indicated in Fig. 1.

As shown clearly in Fig. 7, the shoe 14 which is a typical shoe construction has an inner sole 60 which comprises the bottom of the sole. A top 61 of the shoe is extended below the edges of the inner s ole 60 so as to provide lips 63. The numeral 64 represents a sole which is being applied to the shoe. lll/'hen the shoe is new, the inner sole 60 extends substantially straight, as indicated by dotted lines 65 in Fig. 7, so that a thin space G6 exists between the inner sole and the sole. This thin space is filled with a suitable filler material, indicated at 67, this filler material usually being a mixture of ground cork and glue or cement. `When the shoe is worn, however, the cork or filler 67 becomes conipressed and worn away so that the inner sole y 60 has the curve shown in full lines in Fig. 7.

In using my invention the sole 60 which is to be applied and the bottom of the shoe are coated with a suitable cement, and the sole is temporarily tacked in piace as illustrated in the drawings. The last of the invention is inserted into the shoe 14, the sections 11 being in a collapsed position. The handwheel 28 is then rotated so that the head 29- is advanced downward in the channels 21 to the position shown in Figs. 1 and 3. This causes an expanding of the sections 11and causes the rims 42 to move into positions at the extremities of the bottom of the shoe. r1`he rims 42, as illustrated clearly vin Fig. 7, rest above the lips 63 and above the extremities of the sole 64. The bulged faces 410i the foot portions 12 follow the contour of the inner sole 60 as illustrated also in Fig. 7. If a full sole is being applied as in the case illustrated in the drawings, the heelpiece is placed as shown clearly in Fig. 1,`

this being done before the last is expanded. The shoe and the parts of the invention are then placed in an apparatus shown in Fig. 6,

rllhe apparatus shown in Fig. 6 consists of a pliable bag 68 which is lled with a mobile substance indicated at 69. Extending through a frame 70 is' a screw 71 having a lower head 72 which is adapted to engage the upper faces 13 of the arm 17. As the screw is advanced downwardly, the last and the shoe are forced against the pliable bag 68 so that the pliable bag 68, as shown in Fig.

6, follows the contour of the entire bottom of the shoe, filling in the large cavity which exists between the heel 73 of the shoe and the arch 47 thereof. When the pressure is applied, the ears 36 tend to move downward along the diagonal face 55 of the heel-piece 48 so that an automatic adjustment takes place. This is desirable so that too much pressure will not be exerted at the point 58 whichv engages the arch of the shoe. The

construction of the heel-piece is such that the ears will not be broken down.

The pressure of the last of the invention against the bottom of the shoe is uniform and is extended to all portions of the bottom of the shoe, even the very extremities thereof. The important parts of the invention reside in the rims 42 and in the bulged faces 41. of the foot portions 12. Another feature of the invention resides in the heel-piece 48 which exerts a downward pressure at the. back part of the shoe, but does not break the arch. A still further feature of the invention is that itis adapted for use on different sizes of shoes. Referring to Fig. 8, when an exceptionally long shoe is to be re-soled, an insert-piece 76 may be placed between the heel piece 48 and the last.

Although my invention is described as being particularly useful in the cementing of soles to shoes, it should be understood that Ido not wish to place a limitation on my invention, but wish it to be understood that various modifications may be made which will adapt it for slightly different uses.

I claim as my invention:

1. In a last of the class described, the combination of: a body adapted to be placed in a shoe, said body consisting of a pair of foot portions; means for spreading said foot portions; a bulged face formed on the bottomA of said body and adapted to engage the bot tom of said shoe; and a rim extended outward from said body to the extremities of said shoe, said rim having a fiat lower face.

2r In a lastof the class described, the com bination of: a body adapted to be placed in a shoe; a rim extended outward from said body to the extremities of said shoe; a shank extended upward from said body; and an arm extended forward from the upper end of said shank overI said body.

3. In a last of the class described, the combination of: a body adapted to be placed in a shoe; a bulged face formed on the bottom of said body and adapted to enga e the bottom of said shoe; a rim extende outward from said body to the extremities of said shoe; a shank extended upward from said body; and an arm extended forward from the upper end of said shank over said body.

4. In a last of the class described, the combination of: a body adapted to be placed in a shoe, said body consisting of a pair of foot portions pivoted at the forward ends; means for spreading said foot portions; and a rim extended outward from said body to the extremities of said shoe.

5. In a last of the class described, the combination of: a body adapted to be placed in a shoe, said bodyr consisting of a pair of foot portions pivoted at the forward ends; means for spreading said foot portions; and a rim extended outward from said body to the extremities of said shoe, said rim having a flat lower face. y

In testimony whereof, I have hereunto setmy hand at Los Angeles, California, this 10th day of September, 1926.
