IMPROVEMENT IN LASTS.

Specification forming part of Letters Patent No. 173,426, dated February 15, 1876; application filed .May 28, 1874.

FORD, all of Berlin, in the county of Worcester and State of Massachusetts, have invented an Improvement in Lasts; and we do hereby declare that the following, taken in connection with the drawings which accompany and form part of this specification, is a description of our invention sufficient to enable those skilled in the art to practice it.

The improvement relates to anew mode of cutting the block from the body of the last, and by a single out of the saw, and whereby also the last so made is stronger, and less liable to be broken at the toe by falling, or by rough usage, or in the act of leveling.

The block, as is well known, is usually cut from the last by making a cut across the top of the last near the toe, as shown in dotted lines a bin the figure, this cut extending about half-way or more through the last, and then another cut, 0 I), nearly atright angles to a b,

is made, these two separate and independentlymade cuts meeting at b. The disadvantages of this old mode of cutting, in addition to the fact that it is impossible vto doi't rapidly, and by a single act and continuous saw-cut, are, always line of It is almost imposexcept with the extremest has a tendency to break apart at the junction of the two outs.

cisel y meet.

which invites abreak the destruction of large numbers of lasts, and

a consequent addition to the cost of the boots and shoes.

N ow, to avoid these objections and losses,

by the line a (10, this out then continuing from I such curve to the ankle part of the block at fin any degree of curvature desired, or in a straight line, if preferred.

It will now be seen that there is no danger of breaking by a fall a last so cut, as there is no weak point and no sharp angular part, as

in the old form 5 and there is no possibility,

when making the single cut, of producing the overcutdefect caused in the old method by accidentally making one saw-cut cross the other, thus leaving a gash or weakening crease. The curve near the toe also is of such form as to hold the block to place equally well as when out in the usual angular form.

Having thus described. our invention, what we claim as new, and desire to secure by Letters Patent, isl A last having its upper part, for receiving and holding the block, formed by a continw ous saw-cut, curved from apoint, a d, in the rear of the toe to a point, f, in the ankle portion of the last, substantially as shown and described.
