LAST-BLOCK FASTEN ER. I

SPECIFICATION forming part of Letters Patent No. 417,350, dated December 17, 1889. 7 Application filed June 25, 1889. Serial No. 315,484. (No model.)v

1'0 all whom, it 12mg concern:

Be it known that I, MARCUS L. W'RIGHT, a citizen of the United States, residing at Newton, Sussex County, New Jersey, have invented certain new and useful Improvements in Last-Block Fasteners, fully described and represented in the following specification and the accompanying drawings forming apart of the same.

re The object of this invention is to furnish an economical and effective means of securing the last-block upon the last; and the invention consists, primarily, in the combination, with a vertical central slot formed in r 5 the upper end of the last-block, of a springwire inserted through such slot into-the last, a catch upon the upper end of the spring, and a pin secured transversely to the slot (upon .the outer side of the block) to engage with such catch.

It. also consists in the combination, with such fastening devices, of a spring applied to the last within a recess in the block to lift the block from the last when uncatched.

In the annexed drawings, Fig'urel is a longitudinal section of the last adjacent to the fastening devices. Fig. 2 is a side view of the body of the last. Fig. 3 is a plan of the same. Fig 4 is a plan of the last-block, and

0 Fig. 5 a view of the staple supporting the locking-pin.

a is the body of the last; I), the instep or last-block; c, a spring-wire having one end inserted in the last a and'extended along the upper surface of the last.

d is a recess formed in the underside of the last-block to admit the spring.

fisa central vertical slot formed in the upper end of the block b, and f the spring 3 0 catch-wire inserted in the last and projected upward through the slot.

c is a wire pin applied transversely to the end of the slot, as shown in Fig. 4:, and preferably made in staple form, as shown in Fig. 5,

with its ends inserted in the block b at each side of theslot;

The lower end of the last-block is preferably formed with a point 19 as shown in Fig.

4, to fit a corresponding recess b" in the last,

as in Fig. 3, and the outer end of the spring f is bent into a catch or round eye g, the

under side of which engages with the upper surface of the pin 2, and operates by its pressure upon the pin to hold the point If in the recess 12 and to clamp the upper end of the last-block firmly down upon the last. When the last-block is thus locked in itsworking position, the spring 0 is compressed and operates, when the catch formed by the eye 9 and pin 6 is released, to lift the last-block up with the pin above the eye g. The eye formed in the end of the spring f operates not onlyas a catch by the contact of its under side with the pin 6, but as a handle to bend the spring, which may be readily effected by the fingers vor by inserting a suitable tool in the eye to retract it.

I am aware that swinging catches have been pivoted upon the last to hold the upper end of the last-block, as in United States Patents Nos. 341378, issued May 11, 1886, and 145,082, issued November 25, 1873, and that a catch formed of a spring secured to the last and having its freeend adapted to engage with the last-block has also been used, as in United States Patents Nos. 268,271, issued November 28,1882, and 208,513, issued October 1, 1878; .and I do not, therefore, claim a spring-catch broadly, nor any construction except that shown and described herein.

I also disclaim the above-mentioned patents.

The slot f is intended to fit closely the sides of the spring-pinf, and the pin thus serves, in addition to its function as a catch, to hold the last-block firmly from lateral movement upon the body a. The eye 9 is a convenient form for the catch upon the spring f to engage the cross-pin 6; but the precise form of the catch is immaterial. It is evident that the pin 6 might be formed perfectly straight and inserted in the body of the last-block, across the slot f, without departing from my invention, as it would perform the same function in such case that it does when formed as a staple with its ends driven into the block 5 on each side of the slot. I do not, therefore, limit myself to the construction for the pin shown herein.

YVhat Iclaim, and desire to secure by Letters Patent, is

-1. The combination, with the last a, having the spring f, and catch of the last-block 1),

the whole arranged and operated substai. I tially as set forth. In testimony whereof I have hereunto set I my hand in the presence of two subscribing 1 witnesses. i MARCUS L. \VRIGH'I.
