RICHARD li3. BROOKS, o'FI/IARSHALL,` MICHIGAN, AssIeNoR, *BY 'MnsNE ASSIGNMENTS,

A To I sRooRsA RUPTURE APPLIANCR COMPANY, on MARSHALL, MICHIGAN, 'AIooif PARTNERSHIP `coNsIsTING or ELLEN J. BRoofKs, LoUIs E, RRooKs, yAND HAROLD e. isR'ooHs.`

n Application filed January T 0 all whom t may concern: f y

Be Ait kno-wn that I, RICHARD B. BRooKs, citizen of vthe UnitedA States, residing-at Marshall, county ofGa'lhoum'State ofMichigan, have invented certain new-and luseful Improvements in Trusses, of which the yfollowing is a specification.

This invention relates trusses. The obj ects to f improvements in of the inventionV are:

, First, to simplify such a structure and to' provide a rubber cushion. portion` which, while secu-rely.` held, is readily removable and replaceablev without` the yuseof screws and. clampl devices, .byfsimple manipulation.

Second, to provide improved meansof retaining'and su-ppolitingthe belt andv crossl strap.

Objects relating to details and economies of construction and operation will appear from the detailed description to follow.

I accomplish the objects of the invention by the devices and means described in the The invention is clearly defined in the claims.

A structure which is a preferred embodiment of the invention is illustrated in the accompanying drawing, forming a part of this application,'in which:

Fig. I is a plan v-iew of a trusspad and fragments of the belt and cross strap, from the pad side. Y

Fig. II is a similar view taken from the back or case side.

Fig. III is a detail sectional elevation view taken on line 33 of Figs. I, II and IV.

Fig. IV is a detail cross sectional view taken on line 4-4 of Figs. I, II and III.

Figs. V and VI are front and back views of the invention as applied to an oval pad truss.

In the drawing similar numerals of re'ference refer tol similar parts throughout t-he .j

cross strap, 3 is the back frame or support` for the cushion pad having a strap recess 1 for the belt and an aperture 5 for securing the cross strap end. 6 is the hollow rubber cushion pad hemispherical in form and 0f I A peripheral flange 3l .at all'points.

comparatively soft vulcanized rubber. Across the hard rubber casing'or back 3 is the belt `recess ffwith a cross bar4 4l embracing the belt 1. o The belt is of elastic material and ynormally slightly wider thanthis .recess so that 1t effectively engages the .caseAB and suiports 1t in position by friction ofthe s1 es. f

of thecasing extended into an inwardlyprojecting annular bead 32, forming an'anis on front face nular recess 83, asseen particularly` in Figs'.

lIIandIV, y

The-rubber pad hollowand at itsfperiphery is-recessedby external groove/at .61N with an outwardlyprojecting peripheral bead @conformed to the flange 32 and recess 33 of the cushion ,The pad, being hollow, is very readily compressed andinserted against the case 3 and allowed to expand so that the beads referred to interlock, retaining the structureV very effectively in position lwith a smooth joint The rubber portion of the hand, thoroughly cleansed and replaced or renewed. f

The` cross strap 2 is inserted through a transverse recess 5 in the case, the same forming a retaining bar 5l kwhich is preferably slightly reinforced (see Figs. II and IV). The inner end of the cross strap 2 is folded on itself at 21 and retained by a seam of stitches 22. This enlarges the inner end of the cross strap so thatr it seats within the recess formed between the bar 5l and the body of the case l, effectively retaining the cross strap in place by a smooth joint. At the same time it is very readily removable.

I have not shown the buckles for these' straps, as my invention in no way pertains to them. In Figs. VI and VII I show an oval pad with a back 3 and rubber cushion 6. to receive the belt l, and the cross strap 2 is retained in the .same way as on the circ'ular pad. Y

My improved padis adapted to use generally, but is especiallyy well adaptedto the arrangement of belt and cross strap hereY illustrated. I therefore desire to claim the same` broadly as well 'as specifically, ras

pointed out in the yappended claims.

Having thus described my invention, what The back bar 4l is on the diagonal` ,6 hemisphericaly and I claim as new and desire to secure by Letters Patent is:

l. A truss structure consisting of a casing or body provided with a recess designed to receive the periphery of a soft rubber cushion pad and provided with inturned annular liange forming an engaging ring, a hollow rubber cushion pad, the periphery of which is grooved and beaded to conform to and engage the ring of the said casing or body and project to the periphery thereof forming a shoulder, a transverse aperture recess through the back of the case to receive an elastic belt of slightly larger cross section than said aperture, a transverse aperture for the cross strap, and a cross strap disposed therein with its end folded upon itself and stitched to form an engaging portion, coacting as specified.

2. A truss structure consisting of a casing or body provided with a recess designed to receive the periphery of a soft rubber cushion pad and provided with inturned annular flange forming an engaging ring, a hollow rubber cushion pad, the periphery of which is grooved and beaded to conform to and engage the ring'of the said casing or body and project to the periphery thereof forming a shoulder, and a transverse aperture recess thro'ugh the back of the case to receive an elastic belt of slightly larger cross section than said aperture, coacting as specified.

.low rubber cushion pad, the periphery of which is grooved and beaded to conform to and engage the ring of the said casing or body and project to the periphery thereof forming a shoulder, coacting as specified.

4. A truss structure consisting of a casing or body, a hollow rubber c'ushion pad carried by said casing, a transverse aperture recess through the back of the casing to receive an elastic belt of slightly larger cross section than said aperture, a transverse aperture for the cross strap, and a cross strap disposed therein with its end folded upon itself and stitched to form an engaging portion, coacting as specified.

In witness whereof I have hereunto set my hand.

RICHARD B. BROOKS.
