PEREZ O. OLAPP, OF DOROHESTER, ASSIGNOR TO HIMSELF AND R. W. TURNER, OF MILTON, MASSACHUSETTS.

IMPROVEMENT IN LASTS.'

Specification forming part of Letters Patent No. 59,359, dated November 6, 1866.

To all .whom it may concern:

Be it known that I, PEREZ C. OLAPP, of Dorchester, in the county of Norfolk and State of Massachusetts, have invented an Improvement in Lasts; and I do hereby declare that the following, taken in connection with the drawings which accompany and form part of this specitication, is a description of my invention sucient to enable those skilled in the art to practice it.

The improvement relates to providing or constructing a last with such means of fastening the block thereto as to hold the block securely in place, butin such manner that it may be easily detached from the last by the common hook While the last is in a boot or shoe.

The drawings show at A a plan of the meehanism by which the block is fastened to the last, and at B a section in the line x au of A. G shows a side view of the upper end of the last-block.

a denotes an ordinary last, with a block, b, fitted to or forming part ofthe same.

The upper surface of the block is mortised out to receive a latch-bolt, c, which ts in and slides in Said mortise, its outer end projecting into a mortise in the last, a cap-plate, d, holding the latch down in the block-mortise, and a cap-plate, c, or a staple, or other similar device being applied to the last for the bolt to shoot under, thus locking the block to the last and preventing` its upward or lateral movement, a pin holding the lower end of the block in position in the usual manner.

The bolt is recessed or slotted out to receive a spring, f, which, abutting at opposite ends against a pin, g, and the bolt, tends to hold the latch end of the bolt out from the block,

as will be readily understood.

The upper end of the bolt has a hook or projection, h, with which a short bent lever, z', engages, as seen at A, the other end of the lever extending across the hole or passage k, made for reception ofthe last-hook. a The outer end of the bolt is made inclined, as seen at B and C. Upon pressing down the block in applying it to the last, this inclined end is pressed against the plate e, which causes it to move back until the end slips by the plate, when the bolt will spring forward under the plate, locking the block securely tothe last.

To detach the block, the end of the last-hook is slipped into the hole k, (in the usual manner,) in the direction of the arrow, (seen atA,) Vand as the hook strikes the lever c' and turns it on its vfulcrum said lever draws back the bolt from the last,` When, by pulling upon the hook, the block will be drawn away from the last.

From this description it will be seen that the arrangement of mechanism is simple, cheap, and not liable to get out of order, and that it et't'ectually prevents the block from getting displaced in any direction when applied to the last, while it may be easily detached from or applied to the last whenever desirable.

I claim- Gombining with the last-block and last the spring bolt or latch, arranged to operate substantially as described.
