ESPECIFICATION forming part of Letters Patent No. 388,618, dated August 28, 1888.

Application filed May 28, 1886. Serial No. 203.515. (No model.)

To all whom it may concern.-

Be it known that we, JOHN C. BICKFORD and WARREN I. STE'rsoN, both of Berlin, county of Worcester, and State of Massachusctts, have invented an Improvement in Lasts,

of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts. This invention has for its object to provide. improved means for fastening the blocks of lasts formed by a curved cut therein, as represented in United States Letters Patent No. 173,426, dated February 15, 1876, wherein the block is severed from the body of the last by a curved out, especially at the point where the lower end of the block meets the top of the last, the object of the said curved out being to avoid a shoulder such as commonly found in lasts prior to the date of the invention de scribed in said patent.

The block of the last herein to be described is provided near its upper end with a shoulder or projection to be engaged by alatch con 2 5 nected with the body of the last, the lower end of the block having a pin or projection to cooperate with a shoulder formed by cutting into the body ofthe last below the block, the body of the last having a groove with an inclined 0 bottom which leads into the said shoulder, the latter serving as a slot for the pin connected with the block of the last.

The upper end of the block is also provided with a bar or eye, behind or into which may 5 be readily passed the bent end of the last-hook when thelatch is to be disengaged from the shoulder or projection of the block in order to remove the block from the last, the lasthook during such operation engaging the bar or eye connected with the block and holding onto the same while the block is being removed, which is a matter of very great convenience and saves time over that required to insert the last-hook into an eye bored through 5 the block from side to side, as usual.

Figure 1 in side elevation partially broken out shows a last embodying our invention. Fig. 2 in full lines shows the last and block in vertical section, the dotted lines showing the block as being removed,the said figure also showing a part of the last-hook with its end inserted into the eye of the block; and Fig. 3 shows detached from the block the metal .plate, which is herein shown as constituting the shoulder or projection and the bar or eye.

The body A of the last is and maybe of any usual shape and material. The block B is separated from the body of the last by a curved saw-cut, (represented by a,)asin thesaidpatent. The particular curvature of the saw'cut and its length are immaterial, so long as an abrupt or square shoulder is not formed at the junction of the lower end of the block with the body of the last. The body of the last, after severing from it the block B, is bored, as at a, to form ashoulder, a, one side of the hole made by boring the last, as ata, being thereafter cut away, as at a, leaving a groove with an inclined bottom leading into the bore a. The block Bis provided with a pin, I), the lower end of which, as the block is being inserted into working position,passes down the inclined bottom a of the groove and comes to a bearing against the shoulder a". The body of the last is provided with a spring-supported latch, 7 0, located in a bore, 0, thereof, the head ofthe latch having a beveled upper end and below it a hoolelike projection. The upper end of the block B of the last has attached to it a metal plate, I), shaped to constitute a shoulder 50 or projection, b and leave a bar, b, the said hook or projection being engaged by the latch when the block is in working position, the latch at such time occupying the dotted-line position shown for it in Fig. 2, and the fullline position, Fig. 1, it then engaging the said shoulder or projection b Referring to Fig. 3, where the plate I) is shown separately, it will be noticed that the said plate has an eye made in it,leaving a bar,b"'.

When the last is to be removed, from a boot or shoe, the workman will place the end 2 of the last-hook d into an eye at the upper end of the block and down behind the bar b,forming part of the said eye, until the end of the 5 last-hook meets the inclined end of the latch, and thereafter pressure of the hook against the last will force the latch back, as shown in full lines, Fig. 2, thus disengaging it from the shoulder or projection b and thereafter by a slight further movement of the last-hook, its end 2 catches under the bar b enabling the last-hook to take firm hold of the block in order that the same may be withdrawn from the boot or shoe, the last-hook holding the block, as shown by dotted lines in Fig. 2.

We have herein shown theprojection b" and the bar I) as forming part of a metal plate; but it is obvious that the upper end of the block might be partially bored, and then cut out to leave a shoulder or projection, [2 and a bar-like portion, b but the metal plate is preferred, because of its greater strength and cheapness. A metal pin driven through the block of the last from side to side, and occupying the position occupied by the bar b would, in ourjudgment, he an equivalent for the said bar. After the shoe has been lasted, the last is withdrawn to enable the sole and upper to be united upon a sol'e'sewing or naildriving machine, and thereafter the shoe is rclasted, and to enable thesame last to be used for relasting we have attached the pin to the block rather than to the body of the last, as has heretofore been done. By providing the block with the pin we are enabled to dispense with a great number of lasts.

We claim- 1. The body of the last provided with a shoulder, a and a latch, combined with the block having a pin or stud at its under side at or near its lower end to co-operate with the said shoulder, and at its upper end a shoulder or projection, 6 to be engaged by the said latch, substantially as described.

2. The body of the last and its attached latch having a beveled upper end, combined with the block of the last provided at its upper end with a shoulder or projection, b, and a bar, b substantially as and for the purpose described.

3. The body of the last provided with the spring-latch c, fixed therein, and the block B. separated from the body ofthe last by a curved cut, as a, combined with'a pin, b, at or near the lower end of the block, and the plate I) at or near the upper end ofthe block, and the latch c, engaging the said block, substantially as described.

In testimony whereof We have signed our names to this specification in the presence of two subscribing witnesses.
