This invention relates 'generally to `the manufact-ure of shoes, and has more particu lar reference to a novel shoe arch shaping de-y eient in action, and whichr can be manutao' tured and sold at a reasonable cost.

le invention device consists of a U- s'haped member having one of its arms formed with an elongated tapered aperture shaped to receive a shoe last, and the other arm has a clamping means associated therewith and provided with a 'forming block engageable against the last. One of the steps in a process of manufacturing shoes employing the invention device consists in clamping` the soles of a shoe between the last and the forming block, and allowing the same to harden in this position.

The forming block is removable from the clamping device, and may be replaced by diiierently shaped blocks, or adjustable blocks.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features voi the invention are more particularly7 set forth.

Referring to the accompanying drawing, forming a material part of this disclosure Fig. 1 is a face view ot a device constructed according to this invention.

Fig. 2 is a plan view thereof.

Fig. 3 is a side view thereof.

Fig, 4 is a horizontal sectional view, taken on the line 4-4 of Fig. 1.

Fig. 5 is a vertical sectional view, taken on the line 5 5 of Fig. 1.

Fig. 6 is a perspective view of a forming block used in this invention.

Fig. 7 is a perspective view of another forming block used in this invention.

Fig. 8 is a perspective view of still another forming block.

Fig. 9 is a transverse vertical sectional view of still another forming block.

Fig. 10 is a fragmentary plan view of a shoe to which the invention device is applied, eertain parts being shown in section, and other parts broken away to clearly disclose the construction of the shoe.

Fig. 11 is a vertical sectional view, taken on the line11--11 of Fig. 10.

The reference numeral 15 indicates `generally atl-shaped member turned on' its side so that arm 16 is at the bottom, and arm 17 at the top. The arm 16`is formed with an elongated tapered aperture 18 shaped to permit a flush sitting of the last indicated by rdot-dashv lines 19. rlhe last is of customary construction being of two parts indicated by split line 20. A strap 21j, c0n nected with the last, and rpassed through aperture 18 serves as a grip for pulling the last in place. 'The arm 16 is alsoformed with an aperture 22 positioned to accom modate a last pin 23 engageable with last 19 to hold same against displacement.v

A wing screw 24 threadedly engages the arm 17, and has a ball member 25 formed at its lower end. A forming member l26 is provided at its upper end with a cavity 27 in which ball member 25 engages. Locking plates 28 are secured to the top ot form member 26, and serves to hold Vthe ball member in the cavity. y rlhe bottom v'side 29 of the forming member is curved to a desired shape.

y The forming member 26 may be used when the device is' appliedtoa let shoe, forming member 26,|with a bottom side29 may be used ytor right shoes, and forming member 26EL with a bottom sidev29n may be used for either right or left shoes. p Thevcurved side 29 has one part more curved than the other, and curved side 29 is just opposite to this, while curved side 29L is symmetrical at both. ends.

The modification of the invention illustrated in Fig. 9 discloses a forming inember 30 arranged on the end of screw 24, and provided with an adjustable bottom side 31. This is accomplished by having a movable portion 32 pivoted as at 83 to a stationary portion ot the forming member. A screw 33 tlneadedly passes through the stationary portion and is engageable in apertures 34 in the movable portions so as to lock the movable portion as desired.

The operation of the device consists in arranging the last as shown in Fig. 1, placing a. shoe to be shaped thereon, and operating wing screw 24 to clamp the forming member against the shoe and last. The shoe thus placed must be in a wetted con dition, that is, `.glue in the soles thereof must be undried as yet. After the glue r and shank 37.

dries the shoe may be taken from the device.

Figs. 10 and 1l show a shoe to be placed on the last for the forming operation. This shoe consists of an outer sole 35, a reinforcing strip 36 secured to a shank 37, an inner sole 38 and shoe uppers 39. The dot-dash line 40 illustrates the outline of the shank before it is bent upwards. Glue 41 is placed around the strip 36 and between innersole This is the glue referred to in the previous paragraph.

While I have illustrated and described the preferred form, construction and arrangement of the several elements employed, it will be understood that the device is, nevertheless, susceptible of considerable modification therein, and I therefore reserve the privilege of resorting to all such changes as may be fairly embodied within the spirit and scope of the invention as claimed.

Having thus described my invention, what I claim as new, and desire tovsecure by United States Letters Patent is:

l. A shoe arch shaping device, comprising a U-shaped member, one of the arms thereof being forme-d with an elongated tapered aperture to receive a shoe last, and with an aperture to receive a last pin to hold the last against displacement, a wing screw threadedly engaged in the other arm, and a forming member connected to the screw and engageable aga-inst a last engaged in the said tapered aperture, the said connections between the screw member and forming member being a universal joint connection. y

2. A shoe arch shaping device, comprising a U-shaped member, one of the arms thereof being formed with an elongated tapered aperture to receive a shoe last, and with an aperture to receive a last pin to hold the last against displacement, a wing screw threadedly engaged in the other arm, and a forming member connected to the screw and engageable against a last engaged in the said tapered aperture, the said connections between the screw member and forming member being a universal joint connection and the forming member being shaped with a forming side.

3. A shoe arch shaping device, comprising a U-shaped member, one of the arms thereof being formed with an elongated tapered aperture to receive a shoe last, and with an aperture to receive a last pin to hold the last against displacement, a wing screw threadedly engaged in the other arm, and a forming member connected to the screw and engageable against a last engaged in the said tapered aperture, the said connections between the screw member and forming member being a universal joint con nection and the forming member being shaped with a. forming side adjustably ranged.

4. A shoe arch shaping device compris` ing a U-shaped member, one of the arms thereof being formed with an elongated tapered aperture to receive a shoe last, and with an aperture to receive a last pin to hold the last against displacement, a wing screw threadedly engaged in the other' arm and. formed with a ball member on its lower end, a forming member provided with a cavity at its upper end in which the ball member engages, the forming member ,being engageable against a last engaged in the said tapered aperture, and locking plates secured' to the top of the forming member, for holdingl the ball member in the cavity.

In testimony whereof we have affixed our signatures.
