HERNIAL TRUSS.

SPECIFICATION forming part of Letters Patent No. 792,305, dated June 13, 1905.

Application filed June 14, 1904:. Serial No. 212,460.

To all whom, it may concern.-

1 Be it known that I, FRANCIS B. ALLsHousn, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Hernial Trusses, of which the following is a specification.

My object is to provide a truss of generally improved construction possessing peculiar ad vantages in the matter of fitting it to the body of the wearer and in contributing toward the relief and cure of hernia of the abdomen.

In the drawings, Figure 1 isa partlybroken perspective view of my improved truss; Fig. 2, a similar view of details of the construction of the truss-frame, and Fig. 3 a rear elevation of the truss-pad of the construction I prefer to employ.

My improved truss is of the belt form, and the part which extends across the abdomen and forms the body portion A carries downwardly -extending arms B C. The trussframe consists of a central length or strip portion a of stiff, preferably malleable, metal, flanked by strips or lengths I) b of spring metal, from the outer ends of which extend strips or lengths c c of stiff, preferably malleable, metal having downwardly-extending end portions d in the arms B C of the truss. The spring-sections Z), as I prefer to provide them, are flat, and the sections 0 (Z are round rods. The particular form of the frame-sections may be varied, and, if desired, the entire frame may be formed of an integral length of material tempered or given the desired springy quality at the parts I) and rendered pliable to a desired degree at the parts a c. In the construction shown the flat springs b are provided at 'opposite ends with clips 6, presenting square sockets f to receive the square end portions of the rods (6 0.

The frame is enveloped in a casing of leather or equivalent flexible material sewed along opposite sides of the sections or frame members to hold them in place and has projecting flexible end portions 9 7L. Extending from the end 71 is a strap or band 2', preferably of elastic material. The parts of the casing which envelop the downwardly-projecting parts (Z of the frame and form the arms B C are at right angles to the body or belt portion A and are preferably braced, as shown, by corner-pieces it, also of leather or the like. Extending from the end portion of the arm C at its outer side is a strap or band Z, preferably of elastic material, having means, as the buckle m, whereby it may be lengthened and shortened. On the free end of the band Z is a sliding attachment or wire loop a, adapted to hook over a stud p on the lower end of the arm B. The strap 1' is also provided with a buckle or the like, whereby it may be lengthened and shortened, and carries an attachment, like the wire loop n, to engage a stud g on the end portion 9.

My improved truss is adapted to carry a pad at either or each spring portion 5.

D D are truss-pads formed, as I prefer to provide them, with back plates 9', having segmental series of sockets 7 Each pad is pivotally mounted at its center upon a flat bar 8 midway between the ends of the latter, where by it may be adjusted to diflerent angles thereon. A clamping-bar t is pivotally fastened, by means of a screw 6, to the bar 8 at one end and at its opposite end is adapted to receive a clamping screw t which passes through openings in the adjacent end portions of the bars 2, s and into the sockets r.

The truss may be fitted with great accuracy to the body by the wearer himself by first placing the pad over the hernial opening and then shaping the frame to the body by bending the parts beyond the pads over his hips. The rods a c in said parts may be readily bent by hand in shaping the frame to the body of the wearer, but will retain their shapes against any pressure which may be exerted by the abdominal muscles in use. The springs Z) are bent as shown, their concave faces being at the inner side of the belt. The pressure of the pad or pads may be varied by bending the part a. If bowed inward,

it will tend to relax the pressure, while if bowed in the outward direction it will tend to increase the pressure. The belt when in position passes around the body from a point midway between the two abdominal rings of the inguinal canal in front across the ilium just below the anterior superior spinous process and parallel with the crest of the ilium to a natural position behind in the region of the fifth lumbar vertebra. The belt portion is held directly parallel with and firmly to the abdomen at the point of the inguinal canal and is pressed downward across the ilium until the extensions or arms B C rest firmly on the gluteal muscles. Thus the parts (Z of the frame will, under pressure during initial fitting, be bent to form curves fitting perfectly to the body. The frame, while beingshaped or molded to the body, will retain the pad. directly parallel with and against the abdomen, thus giving a directpad-pressure against the hernial opening at all times. The strap or band Z passes directly across the gluteal muscles and prevents the truss from slipping upward in front. It operates to maintain the pull of the truss or direction of pad pressure in a line through the body from the inguinal canal. The compensatory pressure of the truss is equalized throughout that part of the main belt beyond the arms B O by the arms themselves, the corner-pieces Zr, and thelower band or strap Z. The arms held against the body as described prevent any rocking of the truss-frame with the pad or pads While in place. It will thus be seen that the adjustment of the truss is very simple. The pad may be moved backward and forward upon the part I) to find its right location over the hernial opening and may he changed to any angle, either to the right or left, and the pad may be quickly and easily reversed, if desired.

While I prefer to construct my improvements throughout as shown and described, they may be variously modified in details of construction without departing from the spirit of my invention as defined by the claims.

What I claim as new, and desire to secure by Letters Patent, is

1. In a hernial truss, a belt formed with a front frame portion having outer stiff pliable metal sections conformable to the parts of the body to which they are applied, and an intermediate springy section, substantially as set forth.

2. In a hernial truss, a belt formed with a front frame portion having outer stiff pliable metal sections conformable to the parts of the body to which they are applied, and. provided with downwardly-extending arms at the end portions of the frame, and an intermediate springy section, substantially as described.

3. In a hernial truss, a belt formed with a front frame portion havinga central stifl pliable metal section, springy sections at opposite ends of said central section, and outer stiff pliable metal sections conformable to the parts of the body to which they are applied, and provided with downwardly-extending arms at the end portions of the frame, substantially as set forth.

4. In a hernial truss, a belt formed with a front frame portion comprising a flat springseetion adapted to hold a truss-pad, stiff pliable sections connected with opposite end portions of said spring, and conformable to the parts of the body to which they are applied, substantially as set forth.

5. In a hernial truss, a belt formed with a front frame portion, comprising two fiat spring-sections adapted to hold truss-pads, a stiff pliable intermediate section connecting said springs, and stiff pliable sections connected with the outer end portions of said springs and conformable to the parts of the body to which they are applied, substantially as described.

6. In a hernial truss, a belt formed with a front frame portion having outer stiff pliable metal sections conformable to the parts of the body to which they are applied and provided with downwardly-extending arms at the end portion of the frame, a springy section intermediate of said outer sections adapted to hold the truss-pad, a back belt-strap connected with opposite ends of the upper portion of said frame. and a strap connected at opposite ends with the free ends of said arms, all constructed and arranged to operate substantially as set forth.
