INVENTOI? ATTOH/VEKS LEVI D. YORK, OF PORTSMOUTH, OHIO.

SHOE-LAST.

Application filed May 19, 1913.

To all whom it may concern:

Be it known that I, LEVI D. YoRK, a citizen of the United States, and a resident of Portsmouth, in the county of Scioto and State of Ohio, have made certain new and useful Improvements in Shoe-Lasts, of which the following is a specification.

My invention relates to shoe lasts, my more particular purpose being to give the particular parts of the last such form that they may be readily made of metal without unduly increasing the weight of the last as a whole.

My invention further relates to improving the mechanism of the last for the purpose of increasing the general efficiency of the device.

In this connection it may be stated that the wood suitable for the purpose is becoming scarcer, as well as physically harder to and constructed of metal, preferably shaped by casting. The heel section 4 carries two eyes 6, and the toe section 5 carries a single eye 7 Extending through the eyes 6 and 7 is a bolt 8. This bolt and the eyes 6, 7, collectively form a hinge for enabling the toe section 5 and the heel section 4 to swing within certain limits relatively to each other.

Located within the heel section 4 and integral therewith is a longitudinal web 9,

and a cross web 10, these webs merging into a tubular member 11. This tubular member is provided with a hole 12, the latter being bounded in part by an annular shoulder 11 The heel section 4 is provided with a recess 13, and extending into this recess and pivotally mounted upon a pin 14 is a pawl 14. Engaging this pawl is a leaf spring 15 Specification of Letters Patent.

Serial No. 768,502.

' 14. The toe section 5 is provided with an annular bead 19 encircling a hole 20 in the bottom of the toe section. The hole 20 is adapted to receive and hold a plug of wood, thus forming a suitable surface into which a nail may be driven for the purpose of holding pieces of stock upon the last. The heel section 4 is provided with an annular bead 21, which encircles the upper end of the hole 12, and strengthens the heel section adjacent to the hole.

The pawl 14 under pressure of the leaf spring 15 is normally held in the position indicated by dotted lines in Fig. 1. By

pressing the pawl 14 downwardly, according to this figure, however, so that the pawl enters the notch 18, the-heel section and the toe section are swung slightly apart upon the bolt 8 as a center, and in doing this are made to assume the relative positions which these parts occupy when the device is in action.

The operation of my device is as follows:

The last is placed within a shoe or other appropriate piece of stock, and the pawl 14 is pressed downwardly and into the position indicated by full lines in Fig. 1. This practically locks the pawl within the shoe and slightly distends the shoe in the general direction of the length thereof. The last and shoe are now inverted, the hole 12 being brought down over a pin employed for supporting the last. Work may now be done upon the shoe or equivalent piece of stock,

in a manner well known'in this art. I do not limit myself to the precise construction shown as variations may be made therein without departing from the spirit of my invention.

Owing to the last being made of metal, it is not liable to warp or to change its form in accordance with changes inheat or moisture. If made of light material, its weight need not exceed that of an ordinary wooden last, and changes of temperature do not affect it except to an infinitesimal eii'ect.

I claim 1. A last provided with a heel section having a tubular core serving as a bearing, said heel section also being provided with a strengthening web running longitudinally of the heel section and formed integrally therewith, and with a strengthening web 2. A last including a hollow metallic heel' section having Webs lying in intersecting planes and having a tubular member arranged at the point of intersection of the planes and being integrally formed wit the webs.

' 3. A last including a metallic heel section having a tubular core and having a plurality of websradiating from the core and formed integrally therewith and with the heel section.

4. A last including a heel section having a tubular core and having a plurality of strengthening webs formed integrally with 29 the heel section and bracing the core.

'5. A last including a hollow heel having a tubular core extending between opposite wvalls of the heel and formed integrally therewith, and means Within the heel for 2 Copies of this patent may be obtained for five cents each, b y addressing the Commissioner of Patents,
