SECTIONAL. SHOE-LAST.

SPECIFICATION forming part of Letters Patent No. 703,958, dated July 1, 1902.

Application'filed April 11,1901 Serial No. 55,322. (NomodeL) To (0 whom, it may concern:

Be it known that I, NILS F. HAGsTRoM, a

citizen of the United States'of America, and

a resident of the borough of Brooklyn, -New 5 York city, and State of New York, have in vented certainnew and useful Improvements in Sectional Shoe-Lasts, of which thefollowing is a specification.

My invention relates to improvements in shoe-lasts made in sections adapted to facilitate removal of the last from the shoe when completed by removing it in sections; and it consists of the improved construction whereby the same is simplified and cheapened and the operation improved, as hereinafter described, reference being made to the accompanying drawings, in which- Figure 1 is a longitudinal vertical section of my improved last. Fig. 2 is a transverse section on line 2 2, Fig. 1; and Fig. 3 is a plan view.

The last is first made solid in the usual way. Then the instep portion b is sawed out of the main or sole part a on the lines o d, and the heel part c is sawed off from sole part a, on the line J", said line f intersecting line 0 at a point g, so that the rear extremity h of part b overlaps the upper end of heel part c and line f slopes rearwardlyfrom the intersecting point gto the rear extremityof the lower portion of the heel.

A recess 1; is formed in the face of part a, from which the heel part c of the last is out, said recess extending from near-thebottorn of part a to the surface of said part on which the instep b rests and along the same a short distance toward the .toe, as shown at 1'. An angle-plate of metal j j, provided with a dovetail groove is lengthwise in the part 9', is fitted in said groove '5 z" and suitably fastened, as by screws Z, and a corresponding, dovetail rib m is attached to the surface of part c of the last in such relation to groove is that connecting part c to parta by the said rib and groove matches the parts 'coincidently for use practically the same as a solid last. The instep part b has a dowel-pin n in the front end, which engages with a corresponding socket in the wall of the part a'formed by the out at d, and the rear extremity of said instep part b is detachably secured by a screw 0 entering a screw-tapped hole in the part 7' of the angle-plate, this connection being for ward of the joint by which the sole and heel parts are connected, so that with the rear extension h of part b overlapping the upper end-of heel part6, as before described, all the parts of the-last are rigidly joined practically as substantially as in a solid last.

The severalparts a, b, and c of the last have the usual transverse holes p for connecting the hookused for pulling the last out of the finished shoe.

The lower extremity of the dovetail rib m on the heel part c lodges against the lower wall of the recess 2' in the part a to gage the two parts so as to match properly, and the overlapping extension h of the instep part b on the top of the heel part locks the parts 0 and e in their proper relation for use.

The construction is manifestly simple and cheap, and the mode of operation is obvious and also manifestly simple.

'It is to be noted that the joint of the sole part' and heel part is located as near to the heel of the last as is practicable for utilizing the removable heel part as a slackening device to relieve the stresses and free the last for ready removal from the shoe, and this enables the location of the screw to be so close to the rear extremity of the instep part that its power to hold the heel part from it is greater than if located farther forward, andsucharrangement is manifestly more reliable than a ton gue-and-groove connection of the instep and sole parts,-which must at the best be sufficiently slack to work with some degree of freedom and will wear slack and unsatisfactory in use.

What I-olaim as myv invention is The combination in a sectional shoe-last, of the sole part a, having the instep-recess, and the sloping rear end, and also having the groove '5, 'i, in said end and recess; the angleplate 3,7" provided with the dovetail groove lengthwise in the part j and fitted in said groove 11, 2", the heel part c of the last having the dovetail rib m adapted to fit the groove 10, the instep part b of the last fitted in the instep-recess of the sole part, and the screw 0 connecting the rear extremity of the instep part with the sole part by-screwing into the part j of the angle-plate attached to the rear end and top of the sole part a.
