LEWIS B. WHITE, OF MOSCOW, NEW YORK.

IM PROVEM ENT IN TRUSSES.

Specicaton forming part of Letters Patent No. 53,5 13, dated March 27, 1866; antedated September 27, 1865.

To all whom it may concern:

Be it known that I, LEwIs B. WHITE, of Moscow, in the county of Livingston and State of New York, have invented a new and useful Improvement in Trusses used in Gases of Hernia; and I do hereby declare that the following is afull and exact description thereof, reference being had to the accompanying drawings, making part of this specication- Figure l representinga top view ofthe truss Fig. 2, a front elevation thereof.

Like letters designate corresponding parts A in both figures.

This invention is designed as an improvementon the hernial truss for which Letters Patent of the United States were granted to Ine on the 21st day ot August, 1860.

The construction and arrangement of the bow b and spring s are substantially the same as in my previous patent, except in the manner of connecting them with the lever Z, which supports the pad p. In the former patent the lever was pivoted transversely on the end ot' the bow by means of a single pivot-pin projecting lengthwise from the bow; but, besides the liability of a single pivots breaking or bending from the right direction, that construction did not permit any transverse adjustment of the inclination or angle ot' bearing to be given to the pad to suit different patients and locations-of the hernia.

To obviate the above defects in the present invention two bearings, o o, are employed, which are situated obliqnely upward at an angle of twenty-three and one-half degrees (more or less) to the end of the bow, and the padlever l is pivoted between the bearings, a screw passing through the bearings to form the pivot-pin for the lever. The end of the spring is so formed as to hook into the eye in the short end of the lever, which is bent to an obtuse angle, to suit the position of the spring and give the proper direction to the action ot' the pad. add strength, rmness, and durability to the pivot connection between thefbow and padlever, but the angular position of these bearings is such that the pad can be varied in inclination or the direction of its pressure by merely twisting the bow b slightly, so as just to suit the wearer and make the truss iit easy.

To a projection ofthe long arm of the padlever a pin is attached, as shown, the head ot' which serves as a button to secure the cover to the truss.

I do not claim the mere duplication of bearings; but

What'I claim as Iny invention, and desire to secure by Letters Patent, is-

The two pivot-bearin gs o o, arranged at an angle to the end ofthe bow in relation to the bow and pad-lever, substantially as and for the purpose herein specified.
