3 claims. (ci. ,12a- 96) This invention relates toutru'sses, particularly for the treatment of inguinal hernia, iandhasffor its objects to improve on the padstructur'e; f

such trusses and also on the manner of mount-,

ing and carrying the same whereby to enhance the practical and commercial value thereof.

The invention is fully described in the following specification, and one embodiment thereof illustrated lin the accompanying drawing, in Which- Figure l is a front view of a truss embodying the invention; Fig. 2 is a face view of the pad member, together 'with a fragmentary portion of the member on which mounted, to a slightly enlarged scale; Fig. 3 is an enlarged section on the line 3-3 in Fig. 2, -showing the compression or face member of the pad in normal position; Fig. 4 is a similar section showing said compression or face member in compressed position, and Fig, 5 is a cross-section on the line 5 5 in Fig. 2. Figure 6 is an enlarged view of one of the hip engaging strips.

Referring to the drawing, I designates the pad body which is substantially of plate-formv and round or oblong, as desired, with its front surface substantially flat and preferably rearwardly rounded at the edges, as shown. The body I is faced with a yielding pad or cushion member 2 of soft rubber, or other suitable pliant material for bearing against the body of the :1i-ser. This cushion pad is provided at its inner or rear edge with an inturned flange 3 adapted to yieldingly engage around the edge of the body plate to retain the pad thereto. The outer marginal edge of the pad 2 is provided with a rigidor lbeadlike part 4 extending entirely around the pad and being in contact 'with and backed by the marginal edge portion of the body l. The portion of the pad within this edge ,bead forms a compressible cushion part 5 of concavo-convex form, which is spaced from the body plate I and normally projects outward therefromin a plane common to the outer forward surface of the bead 4, as shown in Figs. 3 and 5.

Upon application of the pad to the part of the body to be treated, the cushion part 5 is compressed by pressure against the body until limited by the contact of the bead 4 with the body in surrounding relation to the rupture, as illustrated in Fig. 4, thus causing a predetermined pressure to be applied to the rupture. The space 6 between the cushion 2 and body plate I forms an air pocket which tends to cushion the action of the cushion part 5. The cushion pad 2 may be easily removed from the body plate and replaced by a'new one when'desired.

l y The mounting for the pad body r`I comprises a U'shap 'ed Vor bail-likel member Iof spring band ymetal stock, with its' legs shortY and pivoted to diametrically spaced ears II on the body plate I near its edges by screws I2. The cross loop of the member I 0 is substantially parallel and disposed in slightly spaced relation to the Iplate I to permit rocking movements of one relative to the other on the pivots I2 and also to permit yielding inward springing movements of said cross loop portion toward the plate. k

A bar I3 is clamped crosswise to the bail member I 0 centrally of its ends by'a bolt I4 which projects through registering apertures in the two and has the nut I5 applied to its inner end between the body plate and bail member in spaced relation to the former. The head end of the bolt I4 is countersunk in the bar. The loop portion of the member I ll seats in a notch I6 (Fig. 5)in the bar I3 to permit limited pivotal adjustment of the bar on the member about the bolt I4, as an axis.

The outer side of the bar I3 is longitudinally grooved to provide a seat for a stiff carrying wire I8 which is clamped thereto by eye-bolts I 9 through the eye of which it extends. In'the present instance, the wire I B also seats in a cross groove in the head of the bolt I4, as shown, to hold it from turning in the bar I3. One or two pads may be adjustably mounted on the wire I5 for the treatment of a single or double hernia,r

as desired. l

The wire I8 at each end laps and is attached to a respective hip engaging band strip 20 formed from at sheet metal stock. This strip is of ogee curve form edgewise thereof to Aadapt it to pass rearwardly below the abdomen, and then upwardly and rearwardly over the hip, and then rearwardly in curved conformance to the body Ilatwise of the strip. The outer end portions of the wire I8 and the strips 20 are encased in leather, or other suitable material, 2 I, which may continue beyond the rear ends of the strips to formconnecting straps around the body, such connection being eiiected in any suitable manner, as well understood in the art.

It is apparent that I have provided a truss pad which is attached to the carrying band for yielding inward and outward movements dueto the yieldability of the spring bail member I0 and also for differential rocking movements both with respect to the axis of the band pivots I2 and the axis of the bolt* I4, thus adapting the pad to lfreely accomodate itself to the part to which applied and to movements of the body. It is alsoA apparent that the cushion facing member 2 of the pad contributes to ease of Wearing and eiciency in use.

I Wish it understood that my invention is not limited to any specic construction, arrangement or form of the parts, as it is capable of numerous modifications and changes Without departing from the spirit of the,` claims.

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

1. A truss of the class described comprisinga, pad body having a pair of spaced rearwardly projecting ears, a U-shaped bail of springmaterial extending across the pad body with its legs short and pivoted to said ears for rocking movements relative to the pad member, a carrying member, and means connecting said carrying member to said bail for limited rocking movements relative to the bail about a pvot transverse to the bail pivot.

2. A truss ofthe class described havingy a pad body with spaced ears projecting therefrom, a 25 shallow U-shaped bail of spring material extending crosswise of said body and having its'legs pivoted to said ears for rocking movements relative to said body, a cross bar pivotaily mounted on the loop portion of said bail for limited rocking movements transverse to. the rocking movements of the bail, and means carried by the bar for clamping engagement with a carrying member.

3. In a truss` of the class described. a band having a wire portion, a pad body mounted on said wire portion for adjustment lengthwise thereof, said mounting comprising a bail member .of spring material disposed crosswise of the pad body and having its legs pivoted to the pad body to have rocking movements transverse thereto, the loop portion of said bail being spaced from the pad and yieldable inward and outward relative thereto, a cross bar mounted on said bail for limited' rocking movements on an axis transverse to the bail axis, the outer side of said bar having a longitudinally extending recess for receiving vsaid wiremember, and eye-bolts on the bar receiving and clamping the wire member thereto.
