IMPROVEMENT IN TR'USSES.

The' Schedule referred to in these Lettera Patent nd msling part of the same,

*awry*- To all 'whom it rmay concern .i

Be itv known that I, E. B. HARDING, of Northampton, Hampshire county, Commonwealth ot' Massachusetts, have invented a new and useful Improved Truss; and I do hereby declare that the following is a full and clear description thereof', reference being had to the accompanying drawings and to the letters of reference marked thereon.

In the drawings-.-

Figure 1 is a plan view;

Figure 2, a side view;v

(Iligure 3, a sectional view of my improvements; an f Figure 4 is a view of an auxiliary spring.

The object of' this invention is to obtain, by means of attaching au improved spring, a truss, which shall be easy ot'wear, which can have its pressure on the afflicted part regulated to different stages of couvrau lescence, aud which shall have an upward pressure against the part ofthe body to which it is applied.

rlhe arrangement of this pad, in connection with the belt for attaching it to the body, and keeping'it in the proper place, is by means of a spring, C, the peculiar construction of which produces the important results ofA giving a more general fit, and bringing no hard substance in contact with the body, except so far as the pad may be considered in that light.

,This spring O, as it will be seen, consists of a frame,

cut out of sheet ste'el, or other spring metal, suitable for the purpose of forming two spring bars D and E, with central cross-piece F, by which'it is attached to thepad and two end bars, G and G, by which the belt is attached, as shown in the figure.

The lower bar D is curved outward from the pad at a greater curve than the upper bar E. This is for the purpose of bringing an upward pressure upon the afdicted part, the greater stiffness of the lower part ofthe spring, combined-with the exteusonof the end or belt-bars G. G, below thelower spring bar, D, and the increased curve of the bar D, all teiyiding to throw the lower part of the pad further inward, and consequently upward, as the Upper part acts as a partial pivot. i

1n order to render the spring more 'or less stiii, as the patient may require at dilferent times, I use au adjustable auxiliary spring, J, which is cut out of sheet metal, in the shape of an H, end inserted between the spring O and pad, the piece H operating in conjunction with both upper and lower'bars.

The spring may be T-shaped, if necessary, to stiEt'en only one bar. A

By means of thescrewv M, connecting the pad and spring piece O, this auxiliary can be applied in a few minutes without trouble, or as equally easily taken off, so that by means of au auxiliary T or H spring, one or both ot' the spring bars E and D may be stiffened at will, while, as'lesspressure becomes necessary to hold the separated muscles together, the auxiliary spring may be removed.

rlhe belt consists of a Asimple strap, of whatever material may be most convenient, and it has no spring or other hard substance init to 'annoy the wearer by chaling, y

Now, having described Vmy invent-ion, What I .claimas new, and desire to secure by Letters Patent, .is-

The spring C, for a truss, when iliade with greater curvature, and prolongations of the lower bar, for producing an upward pressure, all arranged and applied in the manner and for the purpose set forth.
