    J3ailey^s Im'provements in Triisses for Hernia, Prom the foregoing description the nature of the said Invention will l)e clearly understood by those conversant with the trusses referred to ; but it must be stated that these trusses may* be made with india-rubber bearings, or with tin plate or other metal foundation with a coatins: of 5, varnish, or vulcanite and soft india-rubber, or of tin plate or metal and yulcanate only. So also vulcanite alone may be used (in all these cases) without nxetal, or tin, or india-rubber for the pads. The foundation or base of the pad, or pads of vulcanite will receive the binding screw; then the soft india-rubber bearing surface will serve for the saddle bearing 10 and the hernial pad. The back of the foundation or base being of vulcanite or of metal may be made with a flush surface, but with any curve, so that the spring may bear along the outline of the curve secured by the screw, I annex the accompanying Drawings, in which Pig. 1 represents a 55 pl^n yiey^ of a double truss with a continuous spring connection between the hernial pads and the saddle back. This saddle back or bearing is shewn at «, and the hernial pads are shewn by 5, 6. In Pig. 2 the truss is shewn in two parts, each connected to the saddle as described; Pig. 3 shews a back view of the saddle for the single truss ; Pig. 4, a 20 view for the double truss; Pig. 5 shews a view of a single truss with the saddle back; Pig. 6 is a plan view of a vulcanite or compound pad, as described. 0f course the Drawing may be greatly varied so that the object of the Invention is met, that is to say, by corrugating or channelling the 25 convex surface of the hernial pad to cause it to find a seating without the necessity of fastenings. Pig. 7 shews a section of the hernial pad; and Pig. 8, a similar section; but in Pig. 7 the india-rubber is shewn by c, in case the pad should be cut in two by the line x, y; but in Pig. 8 the whole space 30 divided by x^ y, and shewn by c?, may be india-rubber, but in all cases the construction of the truss will be on the principle first described. Having now described the nature of the said Invention, and the manner in which the same is to be performed, I would remark that I 35 do not limit myself to the precise details or configuration of parts described and shewn, as the same may obviously be varied or modified; but what I claim and desire to be secured to me by the herein in part
