I, William Robert Owen Chambers, Joiner, of 13, Alfred Street, Gateshead- on-Tyne, in the County of Durham, do hereby declare the nature of* this inyen- tion to be as follows ; — This invention relates to rupture trusses, and has for its object to facilitate 0 the cleaning thereof, and render them very comfortable in use. To this end, I employ a back-supporting* pad of leather or other suitable material and of any convenient shape, over which is arranged, at the side next the wearer, a covering of any soft washable material. This covering is confined in position by lugs or ears furnished thereon, which are turned over to the other side of the pad and secured by studs or their equivalent passed through slits or eyelets in the lugs or ears and in the parts of the pad corresponding thereto. Thus this covering can be readily attached, detached and reversed. The strap for securing the truss to the body is also preferably made of a soft washable material and connected in a removable manner to a swivelling buckle, 15 rivetted or otherwise attached to the back pad. The said connection is suitably effected, isucli as by a button or stud, fastened to or passed through the strap at a convenient position and engaged with a slit or eyelet in the free end which is doubled over the buckle. The other end of the strap is provided with a length of leather having slits to engage with a projection or stud on the rupture pad, and is likewise removably attached to the strap by a stud or button. The rupture pad is constituted by an air or water filled indiarubber or like cushion of desired shape, preferably lined externally with a piece of asbestos or other appropriate cloth, and retained in position against a metal plate by an outer washable covering, the edges of which are laced or. otherwise connected tj O together at the back of the plate. To the said plate another plate of eorrespond- 20 2i) ing shape is attached bv screws or the like so that the edges of the pad covering are clamped between the plates and the lacing is concealed. The plate, which is at the outermost side of the pad, is formed or provided with a hollow hemi¬ spherical and centrally disposed surface having slois arranged at right angles 30 to each other, and in combination therewith a bolt is employed having its head confined within the cavity formed by the hemispherical surface, and its screwed portion passed through the slots therein, so as to engage the end of the metal strip which carries and exerts the pressure against the pad. A milled nut, which is also operatable by a screw driver, serves to tighten and loosen the pad when 35 required so that it can, through the medium of the slots in the hemispherical surface, be angled or adjusted to any required position and locked there. The pad-carrving and pressure-exerting strip may be made of steel or other suitable metal of an elliptical shape in cross section and is attached to the back support by screws or the like, whilst to allow of adjustment in length it is made 40 in two portions, the end of one of which is widened somewhat and formed with a slot to receive a stud or bolt which is passed therethrough and screwed into the end of the other portion. In lieu of the hemispherical surface on the outer plate of the pad and the [Price 8cl]
