TRUSS.
, SPECIFICATION forming part of Letters Patent No. 413,152, dated October 15, 1889.
Application filed April 26, 1889- Serial No. 303,765. (No model.)
To all whom it may concern.-
Be it known that we, GEORGE M. STREETER, of Philadelphia, in the county of Philadelphia and State of Pennsylvania, and AU- 5 GUSTUS D. SOHLESINGER, of College Point, in Queens county and State of New York, have invented a certain new and useful Improvement in Pads for Trusses, of which the following is a specification.
I 0 Our improvement relates to pads for trusses,
supporters, and like articles.
We will describe a pad embodying our improvement, and then point out the novel features in a claim.
In the accompanying drawings, Figure 1 is a front view of a pad embodying our improvement. Fig. 2 is a back View. Fig. 3 is a side view. Fig. 4. is a central longitudinal section. Fig. 5 is a central longitudinal section of a pad of modified construction.
Similar letters of reference designate corresponding parts in all the figures.
Referring first to Figs. 1 to 4, inclusive, A designates a pad composed, essentially, of a The front or body a is made of soft rubber and of semispheroidal shape. The back a is made of hard rubber. The two parts are secured together by having the soft-rubber front or body vulcanized to the hard-rubber back. As here shown, the front or body a isa complete bag and is vulcanized to the back a, entirely across the front surface of the latter. The back is shown as having a groove win the front 3 5 surface in the edge portion, and the front or body is shown as extending into this groove and as being vulcanized therein. It may be sufficient to simply extend the front or body a into this groove a and vulcanize it there.
In Fig. 5 we have shown a pad of slightly-different construction. In this example of our improvement the back neednot be of hard rubber, for it is covered with a sheet 'of soft rubber a and this sheet of soft rubber a is vulcan- 45 ized to the front or body a and it may be vulcanized through perforations made in the back a, Where the back is not made of hard rubber, and directly to the back when the back is made of hard rubber. Obviously it can be made of metal or any other rigid ma- 5o terial, and the rubber can be vulcanized directly to it, even when it is made of material other than hard rubber, by anchoring the rubber into holes or recesses.
The essence of our improvement is a rigid back and a soft-rubber front or body secured together by vulcanization of the rubber. In order to give strength to the back and to provide a proper length for the tapped hole a, the imperforate back is thickened at that part immediately surrounding the hole.
The pad is inflated with Water or air. The rigid back is provided withatapped or screwthreaded hole a, for engagement with a spring or other fixture in atruss or like article; but this does not extend all the Way through.
By the construction of pad described we dispense with all the necessity for a textile covering. A textile covering is obj ectionable. The smooth surface of soft rubbernext to the skin is preferable and is not absorbent. Our pad is, moreover, cheaper than those of ordinary construction.
\Vhat we claim as our invention, and desire to secure by Letters Patent, is
A pad having a metal back provided with a thickened portion for a screw-socket extending partially through it, a soft-rubber front, a sheet of soft rubber covering the back and vulcanized to the front, and the rigid back being provided With'a groove in its edge for the reception of the edge of the soft rubber, substantially as specified.
