UNITED STATES PATEN T OFFICE.

JOHN C. F. DEECKEN,

OF NEW YORK, N. Y.

SHOE-LAST.

Specification of Letters Patent No.

To all 'whom it may concern.'

Be it known that I, JOHN C. F. DEECKEN, of the city, county, and State of New York, have inventedv new and useful Improvements on Lasts for Boots and Shoes; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the annexed drawings, making part of this specification, in which- Figure l, is a vertical cross section Fig. 2, a horizontal view of my improvements.

Similar letters of reference indicate corresponding parts in these figures.

The nature of my invention consists in so constructing a last that the wooden pegs of the boot or shoe may be cut conveniently while the boot or shoe is onthe last.

To enable others skilled in the art to make i and use my invention I will proceed to dey avoid this I have constructed my last in the following manner: On the sole of the last there is a groove A running all around and nearly parallel with the edge of the same. In this groove an endless chain B is placed, so constructed that it may be moved by a toothed wheel C, placed on the heel and gearing into the said chain; knives or cutters E are attached to some of the links of the chain in such a manner that the same project above the upper surface of the chain, and reach nearly to the outer edge of the sole. On the inside of the groove there are small horizontal incisions 0, o, o which serve 22,942, dated February 15, 1859.

to keep the knives in the position shown on the drawing, when the chain is moved in the direction of the arrow; when moved in an opposite direction, these incisions do not retain the knives in this position, and consequently the said knives rotate on their axles or pins a, (which are the same pins forming the connection of the links of the chain) thus changing their position into one parallel with the chain. The axle D of the wheel C may be prolonged through the body of the last and may thus be turned by a handle (not shown on the drawing).

The edge of the sole of the last C I have formed of prepared leather for the purpose of removing and replacing the same, when too great a number of pegs have been driven into the saine. This last is operated and used in the following manner: The leather for the boot or shoe is stretched on the same and the sole is pegged in the usual manner. The wheel is then turned in the direction indicated by the arrow and the chain with its knives will turn in the same direction, and will cut all the pegs. The wheel is then turned in the opposite direction, when the last may be disengaged from the boot or shoe by gently pulling the same. The covering plate a serves to prevent the contact of the machinery of the last with the leather.

I do not limit myself to the particular shape of the endless chain, the wheel or the knives, but

That I claim as my invention and desire to secure by Letters Patent is:

The endless chain or band in combination with a knife or knives operated in the manner and for the purpose substantially as described.

Dated New York January 9, 1859.
