Specification forming part ofLetters Patent No. 146,155, dated January 6,1874; application filed November e4, 1873. y

To all 'whom it may concern: p

Beit known that I, GEORGE K. WINGFIELD, of Brooklyn, in the county of Kings and State of New York, have invented an Improved Suspeuder-Sprin g, of which the followin gis a speciiication:

This invention is designed chiefly to be used in the back ends of suspenders and braces, and is intended to furnish a spring at that point which will yield to the tension which is thrown upon the suspender or brace when the body is bent forward, and` thus relieve not only the Suspenders or braces, as the case may be, but also the buttons and pantaloons, from undue strain, while at the saine time the spring is designed to hve suicient elasticity to recover its position and hold the pantaloons in their proper place when this tension is removed.

My invention consists in the peculiar construction hereinafter described, by which the spring and its connections are brought into practical shape for use, and into small compass, and at the same time rendered capable of being made sufficiently strong and elastic, and of sufhcient range of action, to answer the purpose required.

Figurel is a back-side view of my invention, with a piece of leather at the upper end to attach it to a pair of Suspenders, and a ring at v the. lower end to connect it to the suspender ends, which are to be buttoned to the back buttons of the pantaloons, the body of the spring being in this figure represented as covered with leather. Fig. 2 is a like view of my invention without the vcoverin g and means of at tachinent above mentioned. Fig. 3 is a similar view with the back plate omitted, and the part of the front plate of which the loop to receive the ring is formed being left straight to show more clearly the lower end of the upper draft-plate. Fig. 4t is a back-side view of the front plate before the loop for the ring is formed, and of the spring. Fig. 5 is a vertical transverse section, showing the parts (without the covering and attachments) put into place upon each other, but not fastened together, and the loop for the ring not being formed.

A is the front plate, which may be made of brass or any other appropriate material, and which has an extended end, a, of which to forni the loop for the ring, as shown in Figs. l and.

per end with a loop, e, to receive the leather attachment C, and at the lower end is bent over into a ange at right angles to the main plate, as shown at g in Fig. 5, to catch the lower end of the spring f. This spring f is a` narrow fiat spring, bent into the form shown in Fig. 4. I prefer that it should be made of i steel and properly tempered. To prevent too great strain upon the spring f, a slot, extending only as far as the flange g should be allowed to go, is cut through the plate A, as shown in Figs. 4. and 5, and a corresponding port-ion of the flange extends through it "to form a stop forthe plate B, and prevent its compressing the spring j' :more than it will` safely bear. D is the back plate, which is formed with notches to receive the projecting' portions d d of the front plate, and is designed merely to keep the draft-plate B in place, and` to hold the end of the loop a in position.

In putting the parts togetherafter they are made ready, the spring f is yplaced in position on the back side of the front plate, as shown in Fig. 4, its upper `end bearing against the iian ge b; the draft-plate B is then laid on, as

shown in Fig. 3, the flange at its lower end` being outside of the spring f, and the extended portion of the said iiange fitting into the slot in the front plate alreadymeutioned. The loop a. is then formed and the ring E inserted, the' end of the loop a being turned down between the lower projections d d and those next above, to secure it in position 5 the outside or back plate D is then put on, and the projections d i d turned down to secure it in position, as shown in Fig. 2, when the device is complete with the exception of the covering and upper at tachment C; and when these are supplied, it is ready to bev attached to the suspenders in the usual manner.

It will be obvious from the foregoing description that the improved suspender-sprin g may be made very thin to adapt it to be Worn, and at the same time can be manufactured at a moderate cost, and yet made sufficiently substantial, elastic, and durable to perform the service for which it isY designed.

The necessity of some elastic device capable of saving the back portion of the pantaloons and the back suspender-buttons from unf due strain when the body is bent forward, and at the same time keeping the pantaloons in their proper position,"ha's been long felt, and various devices have been essayed or adopted for that purpose, among which is that of Weaving india-rubber into the web of the suspender to give it elasticity-an elasticity which is nearly lost after the suspender has been Worn only a short time, and Which elasticity being distributed through the length of the Web necessarily involves a dragging of the suspender over the underclothing on the rounded portions of the body as the body is bent.

An attempt has also been made to secure elasticity by the introduction of spiral springs into Suspenders but these involve too great thickness to be conveniently Worn, and are, besides, liable to get out of order.

By making the spring in a zigzag form, as described, and securing it in the manner described, these difficulties are obviated, and a serviceable spring for Suspenders, giving elasticity at the proper place, is the result.

I claim as my invention- Y l. The combination of the zigzag or serpentine spring f and the metal plates A and B, substantially as hereinbefore set forth.

2. The combination. of the zigzag or serpentine spring f and the plates A, B, and D, substantially as hereinbefore described.

3. The combination of the spring j', plates A B D, and ring E, the end of the loop a oi the plate A being secured between lugs cl d on the flanges c c, or in notches therein, substantially as hereinbefore set forth.
