SURGICAL TRUSS.

SPECIFICATION forming part of Letters Patent No. 273,228, dated February 2'7, 1883.

i Application inea June 5,1832. (Model.)

To all whom -it may concern Be it known that I, JACOB EDsON, a citizen ot the United States, residing at Boston, in the county ot' Suiolk and State ot Massachusetts, have invented certain new and useful Improvements in Surgical Trusses and I do hereby declare that the same are fully described'in the following specification and illusjusted without. undue pressure upon other tion ofthe curved holder.

parts of the body.

The invention is carried out as follows, ref erence being had to the accompanying drawings, on which- Figure l represents a perspective view of my improved truss. Fig. 2 represents a crosssection ot" the spring belt on the line A B, shown in Fig. 1. Fig. 3 represents a front view of my improved composite pad and a por- Fig. 4 represents a back view of the improved pad. Fig. 5 represents a cross-section of the pad on the line O D, shown in Fig. 3. Fig. 6 represents a longitudinal section of the improved pad on the line E F, also shown in Fig. 3. Fig. 7 represents an outside view ot' the rear pad. Fig. S represents a longitudinal section on the line G H, shown in Fig. 7; and Fig. 9 represents a cross-section on the line I K, also shown in Fig. 7.

Similar letters refer to similar parts whereever they occur 011 the different parts. of the drawings.

a is the steel spring, as usual, which spring is covered on its outside with a suitable covering-strip, b, made ot' cotton, linen, silk, or material suitable for the purpose. On the inside the sprin gis covered by the strip or band of felt c, which is made like the outer cover, b, somewhat wider than the spring a, outside of which the inner and outer coverings, b c, are united together by sewing, as shown in Fig. 2. As bel'ore stated, the top and bottom edges, o c', of the inner felt band or lining c project beyond the upper and lowergedges ot' the steel spring a, as shown in Fig. 2, by which I provide' very soft and anti-chating edges of the felt lining c above and below the edges ot' the spring a. The felt lining or belt-cushion c is made of proper thickness and density, so as to eliminate heat and moisture and at the same time be'easy and comfortable to the wearer.

The rear end of the steel spring ais provided with a rear pad or rear support, which is made as follows: It consists ot an outer met-al plate, d, beneath which isV arranged the holder e., made of leather or other suitable material, the edges ot' which project a little beyond the metal plate d, as shown in Figs. 7, S, and 9. On the inside of the steel spring a., beneath the leather holder e, is located the felt pad or cushion f, having its outer edges projecting bcyond the leather holder e, so as to form a soft, comfortable, and non-heating edge for the iuside of the aforesaid rear pad. rlhe said rear pad or support is secured .to the end ot the spring a by means of the screwsg g, which pass through perforations in the felt cushionf, steel spring a, leather holder e, and the elastic belt z', and are screwed into the screwthreaded sleeves d d', which are cast on the inside of theA metal plate d. rl`he upper and lower edges ot' the leather holder c and `felt cushion fare united together by means of stitches, as shown in Fig. 9,and form together, as it were, a tube, into which the end of the elastic belt t' is inserted and in which it may be adjusted to obtain the desired tension previous to securing the cushion j', leather holder e, and spring a to the metal plate d. Thus it will be seen that the rear pad above described serves also as a buckle for holding and adjusting the length of the elasticstrap or belt fi. Thelatter may be lengthened or shortened at any time simply by unscrewing the screws g g and sliding the elastic belt 'i forward or back, and when properly adjusted it is again secured in place by screwing up the screws g g through correspondingholes in the elastic belt i andinto-the screwthreaded sleeves d d in the metal plate d.

By making the inner lining, c, for the spring a of felt its edges are always kept soft and comfortable without the annoyance of ripping or unraveling, as would be the case if cloth or a similar woven lining were used, as the edges ofthe felt will, as they wear ofi', retain their e erases normal soft, yielding, and comfortable condiball o between the perforated part of convex tion, and this is a great advantage in the construction of surgical trusses.

The felt lining of both the spring c and rear pad may be removed whenever so desired to cleanse them iu case they-should become soiled or sticky, or replaced with new ones ata very small expense.

My improved composite pad is constructed as follows: It is composed of an inner convex metal shell, k, and an outer metal plate, Z, between which is secured the feltor deer-skin cushion m,.having its outer edge projecting beyond the outer edges ofthe inner metal shell, k, and outer metal plate, Z, as shown in Figs. 3, 4, 5, and 6. The dotted lines in Figs. 5 and 6 show the curvature of the felt cushion m when the improved composite pad is in use, and in this manner I produce a very soft and comfortable as well as agreeable pad-cushion, and by its use the pad is prevented from being pressed too far into the ruptured place of the body. The inner convex metal shell, 7e, outer metal plate, Z, and felt cushion m are firmly secured together by means of the screws mm, which pass through holes in the outer metal plate, Z, and cushion m and are screwed into screw-threaded projections Zt" 7a It" ou the inside of the convex shell k, as shown in Fig. G.

Through the convex shell k is inade a suitable perl'oration, into which is made to rest the ball o of the curved metal holder o, as shown in Fig. 6, which ball ois held in place by means of tapering tubular projection Z on the metal plate Zin such a manner asfto allow the extreme portion of the ball o to project slightly beyond the convex shell Zr, so as to form a stationary fulcrum, resting on the ruptured part, and on such stationary fulcrum the iniproved composite pad may move or turn, according to the position or motion of the wearer, and in this manner the efficacy ofthe pad and truss is materially increased.

The outer metal plate, Z, is provided on one side with a slotted opening, Z, extending from its center outward to its edge, so as to enable the shank of the curved holder o to be placed in its proper position, so as to place the shell Zr and inner end of tapering tubular projection Z', by which a universal-joint connection is established between the pad and its holder. The curved metal holder o isjointed to the perforated regulator-disk p by means of the adjustable set-screwq. Theregulatondisk p is riveted or otherwise secured t0 the forward end of the metal spring a, and the relative position of the curved holder 0 to the regulatordisk 1J is obtained, as usual, by interlocking the usual projection on the outer end ot the holder o with any desired perforation, p', on the regulator-disk p.

Upon the front of the regulator-disk p is made a hooked projection, a, which serves torthe purpose ofhocking and securing thereto the perforated strap r, which is attached to the front end of the elastic belt t', and by this means a very easy adjustment is obtained for securing the pad in place. By making the holder ocurved, as shown, it enables me to adjust the pad at any desired inclination toward the body, so as to fit properly to the ruptured part without hinderance, and to occupy the least possible space.

That I wish to secure by Letters Patentand claim is l. In a surgical truss, the rear pad, with its fastening device and elastic-strap holder combined, consisting` of the outer metal plate, d, holder e, felt cushion j', and fastening-screws g g, as set forth.

2. In combination, the convex metal shellk, outer metal plate, l, intermediate and outwardly-projecting cushion, m, and holdero with its ball 0, as described.

3. In combination, the convex shell 7c, outer metal plate, Z, with its slot Z, intermediate and outwardly-projecting cushion, m, and the holder 0 with its ball o', as and for the purpose set forth.

In testimony whereof I have affixed my signature in presence of two witnesses.

JAUUB EDSON.
