    A. <$■ W. Coles' Improvements in the Construction of Trusses for Cases of Hernia. following statement, reference being had to the Drawings hereunto annexed, and to the figures and letters marked thereon, that is to say :—. Our said Invention relates to certain improvements in the construction of trusses, whereby the same truss can be adapted and rendered applicable to 5 several distinct cases of hernia. The kind of truss to which our improvements are applicable is that for which Letters Patent, bearing date the Fifth day of July, One thousand eight hundred and twenty-one, and numbered 4567, were granted to William Coles, since deceased, and in which the pads are constructed with spiral springs for 10 the purpose of adapting and equalising the pressure thereof. In the case of these and of all other trusses hitherto made, it has been necessary to have the trusses expressly manufactured for each description of abdominal hernia, inasmuch as it is requisite that the pads should be at different angles to the body spring, according to the kind of hernia under treatment. This objection 15 is obviated by our said Invention in the following manner :—A piece of metal, constructed with a longitudinal slot therein, is connected with the body spring of the truss by means of a set screw, which acts as a pivot and works in a smaller slot at one end of the said piece of metal. The front pad is connected by its back with the slotted piece of metal by set screws passing through the 20 longitudinal slot, thus enabling the pad to be shifted and fixed by means of the set screws, the result being that the truss can be lengthened or shortened, as may be desired, while, by reason of the said slotted piece of metal being pivoted to the body spring, as before mentioned, it can be placed and fixed at any required angle thereto. It will be manifest that by these arrangements 25 the same truss can be rendered applicable to cases of inguinal, femoral, scrotal, or crural hernia, or, in fact, any other description of abdominal hernia, by simply adjusting, in manner before mentioned, the position of the pad and the angle thereof with reference to the body spring. The posterior end of the body spring is also furnished with a longitudinal slot, whereby the back pad 30 can be altered and adjusted, set screws being employed for fixing the same, thus affording an additional advantage over the trusses in ordinary use. Although in the preceding description the arrangements requisite for single trusses are only spoken of, yet our said improvements are equally applicable to double trusses. 35 Our Invention will be more clearly understood by reference to the annexed Drawings. Figures I. and II. in Sheet I. represent respectively a single and a double truss. In Sheet II., Figure I. is the before-mentioned piece of metal, which is attached to the body spring, a is the longitudinal slot, and b the slot by
