Application filed September 7, 1909.

Patented Feb. 1, 1910.

Serial No. 516,600.

To all whom it may concern:

Be it known that I, S'rErI-IEN T. HEN- NnssY, a citizen of the United States, re` siding at. Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Lasts, of which the following is a specification.

My invention i'elates to separable lasts, and its objects are to provide a separable last having a readily detachable toe block; to provide such a last which shall be rigid when in use but which may be readily rendered yielding for the purpose of removal from the shoe; to provide a last which yields where the human foot yields, and to provide a last which shall combine the advantages of a solid last and a collapsible last.

My invention consists in the parts and combination and arrangement of parts hereinafter described and claimed.

In the drawings, Figure 1 is a perspective view of a last embodying my invention. Fig. 2 a perspective view of the instep block, a part being cut away to show the interior construction; Fig. 3 a pcrspective view of the heel-and-arch block; Fig. 11 a perspective view of the toe block; Fig'. 5 a side elevation of the instep block showing the side opposite that shown in Fig. 2; and Fig. 6 a detail.

The reference numeral l designates the heel--and-arch block 2 the instep block and 3 the Atoe'block. The heel-and-arch block terminates in a face 4, preferably curved and adapted to register with a corresponding face 5 on the rear of the toe block, the lower line of junction being approximately where the arch, or shank, ends and the broad sole begins. The instep face of the heel-and-arch block is provided with a longitudinal slot 6, adapted to receive a guide and fastening rod 7 connected with the Vin' step block by a thin plate or fin 8, secured in a longitudinal slit 9. To the instep face is secured a plate 10, preferably of sheet metal, provided with a narrow longitudinal slot 11 registering with slot 6 and adapted to receive the fin 8 of the guide rod 7. The plate 10 extends beyond the front end of the heel-and-arch block and, at its free end, is rolled to provide an abutment 12. The toe plate is provided with a slot 13 adapted to receive the free end of plate 10, the slot terminating` in a bore, or enlargement, 111 adapted to receive the abutinent 12. The end face 15 of the instep block is cut to correspond with the upper rear face 16 of the toe block. Guide rod 7 extends beyond the front face of the instep block, and is adapted to take into a socket 17 in the toe block. A spring pin 18, inounted on the heel-and-arch block, and adapted to take into an aperture 19 in the instep block, serves to lock the instep block in position.

In asseinbling the last, the toe piece is slipped over its free end of plate 10 until the two blocks are in proper alinement. This will bring socket 17 into alinement with guide slot 6, and the abutinent 12, engaging with the walls of the bore 14, will lock the blocks against longitudinal movement relatively to each other, the joint, however, being' somewhat flexible. The instep block is then positioned by inserting the guide rod in slot 6 and sliding the block into engagement with the toe block. The free end of the guide rod takes into the socket 17, and looks the toe block in alinement with the heel-and-arch block and the instep block. As the instep block reaches its position of use the spring pin 18 takes into aperture 19 and the three blocks are firinly locked together. By forcing the spring` pin out of v most effective for withdrawal purposes.

By making the main, or body portion of the last to' include both heel and arch it is possible to use a large number of toe blocks of different, form with a single heel-andarch block of a given size and height of heel, and the same toe blocks may be used with all lasts of the same size, without regard to the height of heel, thus avoiding the necessity of keeping individual lasts for each style of toe and a series of such lasts for each height of heel.

By making the metal plate on the instep4 face of the same thickness as the kerf made in separating the heel-and-arch block from the instep block, the necessity of allowing for the kerf in turning the last is avoided, and a last is produced which has no unfilled oints which might injure the shoe.

I claim as my invention:

1. A last comprising a heeland-arch block; a toe block adapted to be detachably and fiexibly connected therewith; an instep block; and means for looking the toe block into rigid engagernent With the heel-andarch block.

2. A last comprising a heel-and-arch block; a toe block adapted to be detachably and fiexibly connected therewith, and an instep block adapted to lock the toe block into rigid engagement With the heel-andarch block.

3. A last comprising a heel-and-arch block; a toe block adapted to be detachably connected the-rewith; an instep block; gua-rd elements in the heel-and-arch block and the toe block; and a guide rod carried by the instep block, adapted to take into the guard elements and lock them in engagement.

4. A last comprising a heel-and-arch block; a toe block adapted to be detachably and fiexibly connected thereWith; an instep block; guard elements in the heel-and-arch block and'the toe block; and a guide rod carried by the instep block, adapted to take into the guide elements in the heel-and-arch block and the toe block and lock them in engagement.

5. The combination in a last of a heel-andarch block having a longitudinal slot in its instep face; a plate secured to the instep face having a slot registering With the slot in the block; the plate extending beyond the front face of the block, and provided with an abutment at its free end; a toe block having a slot adapted to receive the free end of the plate and hold it against longitudinal movement; an instep block; and a guide rod carried thereby and adapted to take into the slot in the instep face of the heeland-arch block and lock the several blocks against lateral displacement.

6. Thecombination in a last of a heel-andarch block having a longitudinal slot in its instep face; a plate secured to the instep face having a slot registering With the slot in the block, the plate extending beyond the front face of the block, and provided with an abutment at its free end; a toe block having a slot adapted to receive the free end of the plate and hold it against longitudinal movement; an instep block; a guide rod carried thereby adapted to take into the slot in the instep face of the heel-and-arch block and lock the several blocks against lateral displacement; and means for looking the instep block in position.

7 The combination in a last of a heel-andarch block having a lonfritudinal slot in its instep face; a fiexible pzlate secured to the instep face having a slot registering With the slot in the block, the plate extendlng beyond the front face of the block and provided with an abutment at its free end; a toe block having a slot adapted to receive the free end of the plate and hold it against longitudinal movement; an instep block; and a guide rod carried thereby adapted to take into the slot in the instep face of the heel-and-arch block and lock the several blocks against lateral displacement.

8. The combination in a last of a heel-andarch block having a longitudinal slot in its instep face; a plate secured to the instep face having a slot registering With the slot in the block, the plate extending beyond the front face of the block, and provided with an abutment at its free end; an instep block; a guide rod carried thereby extending beyond the front face of the block and adapted to take through the guide slot in the heeland-arch block; and a toe block having a slot adapted to receive the free end of the plate and its abutment and a socket adapted to receive the free end of the guide rod.

9. The combination in a last of a heel-andarch block having a longitudinal slot in its instep face; a plate secured to the instep face having a slot registering with the slot in the block, the plate extending beyond the front face of the block; and provided With an abutment at its free end; an instep block; a guide rod carried thereby, extending beyond the front face of the block and adapted to take through the guide slot in the heeland-arch block; a toe block having a slot adapted to receive the free end of the plate and its abutment and a socket adapted to receive the free end of the guide rod; and means for looking the instep block in position.
