TRUSS 1? Application filed July 29,

My invention relates to a new and useful truss pad, and the method of making the same, truss pads may be mad whereby more durable and lasting e and at a considerable saving of time, labor, and material.

It has been the practice in making truss pads heretofore, to soon resilient spongy rubber plate, core, layer of soft, In so covering and then to cover as well-as the metallic plate, with a pliable and waterproof leather.

the truss pads with re a filler or core of to a metallic form the rubber filler or leather it was necessary to 'form a bead around the edge of the truss pad.

manual operation, that This was done by a is, by taking a suitable beading material such as twine, rope or the like, laying the beading mater al around the edge, and sewing it together with thetwo leather plies. tion it was necessary to the leather covers,

Due to this construcefi'ect the sewing of by a manual operation, which consumed a considerable amount of p the filler and folding the edges thereof over time, and the result was not entirely satisfactory.

Moreover, it has been the practice, first separately to encase the sponge rubber filler encased metal plate, of the gauze-encased in a cotton securing the gauzestitching together the gauze covers, around the peripheral edge of the metal plate. A

piece of pliable waterproof leather of a size the fr li sufficient to cover then provided witha ont of the filler, was mp peripheral bead,

by folding the edges thereof inwardly around a beading material and loosely stitching the turned-over edges of the leather, so as to encase therein. This front Ie the beading material ather cover, having the limp peripheral bead encased loosely in the inturned edges to the filler, while a cover was applied over t thereof, was then applied thicker back leather he metal plate. The

limp beaded edge of the front leather cover was then "stitched by hand to the edge of the back leather cover, throughout the peripheries thereof, thus comp letely enclosing the the beaded PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO CHESTER PHILADELPHIA; PENNSYLVANIA, A CORPORATION OF 1926. Serial No. 125,649.

gauze encased filler and metal plate in the front and back leather covers respectively.

The object of my invention is a truss pad. of simplified construction, and one which may be assembled more quickly, and without any hand sewing or stitching, with a minimum number of parts, and a minimum number of operations.

Accordingly my invention contemplates the provision. of a preformed and shaperetaining, relatively rigid bead, made by sewing or otherwise securing a beading material around the peripheral edge of a relatively rigid and form-retaining piece of fibrous material, such as sized burlap, buckrainete or the like.

My invention further contemplates securing this beaded piece of form-retaining ma terial to the fiat base of a sponge, or other, resilient rubber filler or core, by adhesive or other means, applying the pliable and waterroof front leather cover over the front of the pre-formed and shape-retaining bead and securing thesame on the back of the burlap or bead-supporting sheet, by adhesive or other means. The metal plate is then superimposed upon the turned-over edges of thefront leather cover, on the flat base of the filler pad, and secured thereto by adhesive or other means. A back leather cover, of the same contour as the metal plate, but slightly larger, is then superimposed upon the metal plate, and a row of stitches is passed through the overhanging edge of the backleather cover and through edge of the front leather cover, throughout the circumferences thereof, there by completely encasing the filler and metal plate, to form a finished truss pad.

Due ing operation can be carried out 011 any suitable sewing machine, thereby further eliminating manual operations, reducing the time and cost of manufacture of the truss pads. I

For the purpose of illustrating my invention I have shown in the accompanying to my novel construction, this stitch and thus.

drawings several forms thereof which are at present preferred by me, since the same have been found in practice to give satisfactory and reliable results, although it is to be understood that the various instrumentaliand secure to the ties of which my invention consists can be variously arranged and organized and that my invention is not limited to the precise arrangement and organization of the instrumentalities as herein shown and described.

In the accompanying drawings, in which like reference characters indicate like parts.

. Figure 5, represents a plan view of the back of the truss after the front leather cover has been applied over the filler and the edges thereof folded back over the bead and adhesively secured to the form-retain ing fibrous sheet; showing the third step in the making of my novel truss pad.

Figure 6, represents a section on line 66 of Figure 5, on a slightly reduced scale.

Figure 7, represents a plan view of the metal back plate.

Figure 8, represents a perspective view of the completed truss pad of my novel .con struetion, having the metal plate applied to the back of the pad and having the back leather cover superimposed thereon and secured to the front leather cover by a peripheral row of stitches; showing the fourth and last stepin the making of my novel truss pad.

Figure 9, represents a section on line 99 of Figure 8, on a slightly reduced scale.

By my novel construction I provide a suitable piece of relatively rigid and formretaining piece of fibrous material 1, such a piece of sized burlap, buckramete or the like, and of the desired dimensions and contour peripheral edge thereof a shitable head 2, which may be formed of strands of cord or the like 3, encased in a suitable strip fabric 4, and sewed to the edge of the form-retaining material 1, by a row of stitches 5, as shown in Figures 1 and 2. Byv this means there'is produced a formretaining base 1, having at its edges a preformed bead, which will retain its shape 1, and adhesively secured thereto. The base,

with the filler or core 6 applied thereto, is shown in perspective View in Figure 3, and in section, on a reduced scale, in Figure 4.

The next. step is the application of the pliable and waterproof front leather cover 7, over the front of the rubber filler or core 6, and folding its edges around the bead 2 L and in back of the buckramete or burlap base 1, and also adhesively securing the turned-over edges to the base 1, so as to retain the said front leather cover 7 fixed, while the truss pad is finally assembled. The folded-over edge of the outer leather cover 7 is desi nated by the numeral 8, and is shown more particularly on anenlarged scale in Figure 5. 1 p

I next apply the metal form plate 9, also of the desired contour and size, and of suitable thickness and rigidity, having suitable spaced and threaded apertures 10 and a suitable .knob 11, by adhesively or otherwisesecuring it to the back of the burlap base 1,. as shown in Figure 9. The back leather cover 12 is then applied to the assembly, over the metal plate ,9, as shown in Figures 8 and 9, and the assembly is then ready for the mach'me stitching operation. A single or double row of machine sewn stitches 13, is then applied through the back leather cover 12, and through the front leather cover 7, within the inner periphery of the bead 2. This row of stitches passes inside the inner circumference of the bead 2 and completes the truss pad, by drawing the front leather cover 7 taut onto the rubber core'or fille-rfi, and thus completely encasing the filler, base, and metal plate, in a leather cover.

It will thus be seen that by my novel construction' and more particularly by the provision of the pre-formed, shape-retaining head 2, mounted upon a shaperret-aining fibrous backing material 1, I am enabled to produce a truss pad, without. any manual or hand sewing, rincethe parts to be sewed to gether and thus secured, arer-etained in position, without any manual efi'ort, while the stitches are applied. Moreover, by my novel construction I not only minimize the number of manual operations, but also reduce to a minimum the number of parts, by the elimination of the gauze casings about the filler ployed in truss pads.

It will now be apparent that I have devised a novel and useful construction of truss pad andmethod of making the same which embodies the features of advantage enumerated as desirablein the statement of theinvention and the above description, and while I have, in the present instance, shown and described a preferred embodiment there of which will give in practice satisfactory and reliable results, it is to be understood that the same is susceptible of modification in various particulars without departing from the spirit or scope of the invention or sacrificing any of its advantages.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

1. The hereindescribed method of making truss pads, which consists in forming a bead around the peripheral edge of a formretaining sheet, placing a resilient filler pad on one side of said form-retaining sheet, applying a pliable front cover over the filler pad, turning in the edges of said pliable.

cover around the bead and securing the same to the other side of said form-retaining sheet, applying a rigid plate to said other side of said form-retaining sheet, applying a back cover over said rigid plate, and lastly fastening the front and back covers by a row of stitches passing through the peripheries of the two covers.

'2. The hereindescribed method of making truss pads, which consists in sewing a bead onto one side of a form-retaining sheet, along the peripheral edge thereof, adhesively securing a resilient filler pad on one side of said form-retaining sheet, seated within said bead, applying a pliable leather front cover over the filler pad, turning in the edges of said pliable front cover around the bead and adhesively securing the same to the other side of the form-retaining sheet, applying the rigid plate to said other side of said form-retaining sheet, superimposed upon the turned-in edges of the pliableleather front cover, applying a back leather cover over said rigid plate, and lastly fastening the front and back leather covers, by a row of stitches passing through the periphery of the back cover, and passing through the turned-in edge of the front cover and through the front cover, around the inner periphery of the bead, thereby completely enclosing the filler pad, the form-retaining sheet and the rigid plate.

5. The hereindescribed method of making truss pads, which consists in forming a head around the peripheral edge of a form-retaining sheet, by enveloping a suitable beading material in a suitable strip of fabric, and sewing the longitudinal edges of said strip fabric to the peripheral edge of said formretaining sheet, placing a resilient filler pad on one side of said form-retaining sheet, seated within said bead, applying a pliable front cover over the filler pad, turning in the edges of saidpliable front cover around the bead and adhesively securing the same to the other side of said form-retaining sheet, applying a rigid plate to said other side of said form-retaining sheet, superimposed upon said turned-in edges of said pliable front cover, applying a back cover over said rigid plate, and lastly fastenin the front and back covers by a row of stitc es passing through the periphery of the back cover and pasing through the turned-in edge of the front cover and through said front cover,

around the inner periphery of the bead, thereby completely enclosing the filler pad, the form-retaining sheet and the rigid plate.

4. In a truss pad, a resilient filler pad having a base, a pre-formed shape retaining bead secured to the peripheral edge of the base thereof, a flexible cover extending over the filler Pad, a rigid plate superimposed upon the base of said filler pad, a cover extending from said rigid plate, a row of stitches extending through the peripheral edge of said second cover and through said first cover, around the inner periphery of said bead, fastening the two covers together, thereby completely encasing within them the filler pad, the pre-form'ed bead, and the rigid plate.

5. In a truss pad, a form-retaining sheet,

having a peripheral bead thereon, a resilient filler member on one side of said sheet, a rigid plate on the other side thereof, a flexible cover extending over the resilient filler, a cover extending over the rigid plate, and a row of stitches extending around the inner periphery of the bead, and through said two covers, thereby to secure the two to each other and to encase within them said filler, the form-retaining sheet and the rigid plate.

6. In a truss pad, a basesheet of relatively rigid material of predetermined contour, a preformed peripheral bead carried thereby, a filler pad on one side thereof, a metal plate on the other side thereof, a leather cover enclosing the filler pad and having its edges folded back over the base sheet, a leather cover extending over the metal plate, and a row of stitches extending through the two leather covers and around the inner periphery of the bead, securing the two leather covers together and enclosing within them, the filler, the base sheet and the metal plate.

7 In a trusspad, a form-retaining fibrous sheet having a peripheral head in one side thereof, a resilient rubber filler pad seated within said bead and adhesively secured to said form-retaining fibrous sheet, and pliable leather front cover enveloping said pad and having its edges folded in, over said bead and adhesively secured to the other side of said form-retaining fibrous sheet, a metal plate positioned upon said other side of said fibrous sheet, superimposed upon the turned- (R er edge of said front leather cover, a back leather cover, superimposed upon said metal plate, and-a row 0f stitches passing through the peripheral edge of said hack leather cover, the turned over edge of said front leather cover and said front leather cover; around the inner periphery of said bead, 10 securing said two leather covers to each other, thereby completely encasin-g Within them the filler pad, the. fibrous sheet, the bead, and the metal plate.
