Specification of Letters Patent.

LAST.

Patented Nov. 15, 191i).

Application filed December 11, 1908. Serial No. 466,945.

To all whom it may concern:

Be it known that I, F nnnnnron WY. Mn.- LAY, of Haverhill, county of Essex, State of Massachusetts, have invented an Improve- I subsequently inserted in the hole which has been bored, which projects beyond the main portion of the last, so as to engage the block and act as a stop to hold the same from being pushed toward the toe beyond the point at which it is desired that it be held. In lasts of this character, the inserted wooden pin, above referred to, is a source of much difficulty, for, while this pin is tightly fitted and glued in place, it often becomes loose from various causes, so that the pressure of the block against it causes its lower end to protrude beyond the bottom of the last, or the pressure on the last bottom causes the pin to be depressed, with the result that injury is frequently caused to the bottom of the shoe, or, at least, an indentation is formed on the sole, during the beating out process, which may be removed only with difiiculty, if at all. For this, and other reasons, such as failure to withstand transverse strain, renewal of these pins is often required.

The object of my invention is to provide a form of last block holding pin which is adapted to be readily applied to the last, which will not be forced through the bottom of the last by the action of the last block thereon, and which will be securely held in place, so that renewal of the pin will seldom, if ever, be necessary, but may be readily accomplished if necessary. I accomplish this object by the means shown in the accompanying drawing, in which,

Figure 1 is a plan View of a last provided with my invention, and showing the last block removed. Fig. 2 is a sectional view on the line 2-2 of Fig. 1, showing the last block in position. Figs. 3 and 4: are detail views showing different steps in the process i i I of preparing the last to receive the last block pin.

As shown in the drawing, the main body a of the last and its block b, and spring-locking pin 0, are of ordinary form, the plane of severance of the last block curving upwardly at its lower or front end.

According to my invention, I provide a metal holding pin (Z for the front end of the block, said pin being of cylindrical form and having a tapering screw threaded extension 6, at one end, of much smaller diameter, and approximately half the length thereof. The upper end of said pin (Z is provided with a slot (Z adapted to receive an ordinary screw-driver. In preparing the last to receive said pin, a hole f of small diameter is bored through the bottom of the last up into its block portion, as indicated in Fig. 3, and the block is then sawed from the main body portion on the plane of severance indicated. The hole f in the block is then counterbored to the end thereof, and said hole is also counterbored in the main portion of the last from the side at which the block is removed for a portion of its thickness, forming abore g, as shown in Fig. i, and a shoulder h at the end of the counterbore. The front side of the bore in the block is cut away, as indicated at 2', to the end of the block, as is customary. The pin cl is then inserted in the bore 9, and its extension 6 screwed into the bore f, until the inner end of the pin firmly engages the seat It and the outer end thereof protrudes to an extent sufficient to engage the block. The diameter of the bore 9 and the pin d are the same, so that said pin will fit closely therein, the remaining portion of the bore f being of a size to permit the extension 6 to be tightly screwed'therein, so that the pin is thus firmly fixed in the last, and, as said extension is somewhat tapering throughout its length and is of approximately the diameter of the small bore at its extreme end a seat for nearly the entire end of the plug is provided. The end of the threaded extension 6 terminates a short distance above the bottom of the last, and the diameter of the bore f is so small that there is no necessity of filling it after the pin has been inserted.

With the above described construction, the block-holding pin will be firmly held in position against all strain transversely, and, as the pin also seats firmly against a shoul- Q mps der in the counterbore, said pin will not be forced outwardly through the bottom of the last by the oblique pressure of the block against it.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is A last comprising the main body portion and its block, said body portion having an aperture extending therethrough beneath the front portion of the block, the diameter of the lower portion of said aperture being materially less than that of the upper portion to provide a shoulder therebetween, and a metal block-holding pin tightly fitted in the portion of said aperture of larger diameter, seating at its lower end against said shoulder, and having at its lower end a threaded extension screwed into said aperture of small diameter, the opposite end of said pin protruding to engage the block, substantially as described.

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
