GEORGE E. BELCHER, OF STOUGHTON, MASSACHUSETTS.

LAST.

dPEG-IFIGATION forming part of Letters Patent No. 535,315, dated March 5, 1895.

Application filed July 2, 1894. Serial No. 516,339. (No model.)

To all whom it may concern:

Be it known that I, GEORGE E. BELOHER, of Stoughton, in the county of Norfolk and State of Massachusetts, have invented certain new and useful Improvements in Lasts, of which the following is a specification.

This invention relates to a transversely divided last, comprising a fore-part section, and a heel section which is connected to the forepart section in such manner that it can be moved simultaneously upward and forward to readily release the last from the shoe that has been lasted upon it, the upward motion of the heel section virtually shortening the last, so that it is immediately loosened and is free to be removed.

The invention has for its object to provide improved means for connecting the parts of a last of this class and to enable the last-connecting means to serve also as a protection for the spindle socket in the heel section of the ast.

To these ends, the invention consists in the improvements which I will now proceed to describe and claim.

Of the accompanying drawings, forming a part of this specification,--Figure 1 represents a longitudinal section of a last provided with my improvements. Fig. 2 represents a'section showing a form difiering in certain particulars hereinafter specified, from that shown in Fig. 1. Fig. 3 represents a section on line 3--3 of Fig. 2. Fig. 4 represents a sectional view showing a modification.

The same letters of reference indicate the same parts in all the figures.

In the drawings-a represents the fore-part section, and b the heel section of a transversely divided last.

0 represents a pin or bolt engaged at its forward end with the section a and extending longitudinally through the heel section b to the rear end of the latter, said bolt having at its rear end an enlarged nut c which has a bearing on a seat formed in the rear portion of the section b. The bolt 0 passes through or across the lower portion of the spindle socket d in theheel section, and constitutes a metallic bearing for the j ack-spindle, which is received in said socket, the bolt therefore protecting the bottom of the socket against abrasion and injury from the said spindle.

The forward end of the bolt 0 is engaged with the fore-part section a in such manner as to permit free upward and downward movement of the heel section. The means for connectingthe bolt with the fore'part section may be variously modified.

In Fig. l I show the forward end of the bolt 0 provided with an eye through which passes a pivot-pin e extending transversely through the fore-part section, the bolt being adapted to swing vertically on said pin. In this case the fore-part section a has a curved convex seat or face a, while the heel section has a correspondingly curved concave seat or face 1) bearing on and adapted to move upon the face a of the fore-part section, the two sections being cut away so that when the heel section is in its operative position there will be a considerable space between the limiting faces a and b of the two sections, said faces coming together when the heel section is raised, as indicated in dotted lines in Fig. 1. The fore-part section has a slot a formed to permit the necessary play of the bolt 0 and heel section b, downward movement of the heel section being limited by contact of the bolt with the lower edge of said slot, which is formed to prevent the heel section from being depressed below its operative position.

In Fig. 2 I show the fore-part section pro vided with a fiat inclined face or seat a and the heel section with a correspondingly inclined flat face or seat I) adapted to slide upon the face a. The fore-part section has a limiting face 0?, and the heel section a corresponding limiting face 12 the faces being separated when the heel section is depressed and therefore permitting the simultaneous upward and forward movement of the heel section, the forward movement being due to the inclination of the faces a and b In this case the engagement of the bolt 0 with the fore-part section is efiected by means of a slotted plate a attached to the fore-part section, and a head 0 formed on the forward end of the bolt 0, said head being wider than the slot in the plate a and located in a recess of in the fore-part section, the head c bearin g against the inner side of the plate a and being free to slide up and down in the recess cf".

In assembling the parts of the last, the bolt 0 is first permanently engaged with the forepart section by means of the pivot-pin e in the construction shown in Fig. 1, and by means of the slotted plate a in the construction shown in Figs. 2 and 3. The heel section is then forced on to the bolt, the nut a being removed, and then said nut is applied and turned in until it forces the heel section with the desired firmness against the corresponding seat on the fore-part section, said nut enabling the heel section to be adjusted to compensate for wear of the meeting surfaces of the two sections.

It will be seen that in each of the construc tions shown the heel section is adapted to be readily applied and removed, and has the bottom of its spindle socket protected against wear from the jack-spindle.

In Fig. 4 I showa modification, in which the nut c is omitted and the rod 0 is secured to the heel section by a pin or rivet- 0 driven into the heel section and through a hole in the rod.

I claim- 1. In a transversely divided last composed of a fore-part section and a heel section movable upon the fore-part section, the combination with said sections, of a rod or bolt engaged at its front end with the fore-part section and passing longitudinally through the heel section, said bolt having at its rear end an adjustable nut seated upon the heel section and adapted to press the same against the fore-part section, as set forth.

2. In a transversely divided last, the combination of the fore-part section having a convex seat or face at its rear end, the heel section having a concave seat or face at its front end, and the bolt pivotally connected with the fore-part section and passing longitudinally through the heel section, said bolt having a nut at its rear end seated upon the heel section, as set forth.

3. A transversely divided last composed of a fore-part section, a heel section movable upon the fore-part section, and a rod or bolt extending lengthwise in the heel section and across the spindle socket, said rod being affixed to the heel section and loosely connected with the fore-part section.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, this 27th day of June, A. D. 1894:.

GEORGE E. BELOHER.

WILLIAM QUINBY, HORACE BROWN.
