    JNT 27,812 A.D. 1904 Date of Application, 20th Dec., 1904 Complete Specification Left, 4th Oct., 1905—Accepted, 14th Dec,, 1905 PROVISIONAL SPECIFICATION. “ An Improved Pneumatic Truss for Personal Wear.’’ I James Joedan Sheema^ Berwood Farm, Chester Road Erdington, Bir¬ mingham, in the County of Wai'wickshire Engineer do hereby declare the nature of this invention to be as follows; — A thin rubber bladder, and a detachable outer casing, of any suitable 5 material, preferably a washing material. A Hat steel spring made to the shape of outer casing is hxed to same, by means of the edges of the said outer casing, being turned over the forementioned spring, and secured there. This spring contains two small projections; a narrow opening is cut in each side of the outer casing, to allow of the said projections to pass through. By these means, 10 the outer casing can be securely fixed to the steel or other suitable plate, which is made to the shape of truss pad, having the edges turned down per¬ pendicular from the said plate; these edges contain two small slots. By this means the outer casing can be attached to the said plate, by simply pinching the flat spring to allow of same passing inside the perpendicular edges of l/i plate, and the projections will pass, when loosed, into the said slots. An inner collar can be made in the forementioned outer casing, as a second means of securing same, whereupon inflating inner bladder the pressure of air, will press the said collar tightly to the plate. Hence the outer casing can be fastened by each of the said mentioned ways, separately ; or together if necessary. 20 This pad can be attached to the elastic belt, or to the steel truss band, by means of two threaded studs. A hole is made through the centre of said plate to allow the small valve which is attached to the inner bladder, to pass through same, likewise a hole in belt is made, to allow of the valve passing through. To detach pad, the valve nut is unscrewed to' release the air, the flat spring 25 attached to the outer casing is pinched until the projections are clear of the slots, and the pad is detached. The soiled casing is taken oft, and replaced by a clean one, in a few seconds. Dated this 19th day of December 19(>4. JAMES JOBDAN SHEBMAX. 30 COMPLETE SPECIFICATION.
