TRUSS.
SPECIFICATION forming part of Letters Patent No. 579,235, dated March 23, 1897.
Application tiet'nay 22, 1896.
T a/ZZ whom it may concern.-
Be it known that'I, NELSON Y. HULL, aciti-v zen of the United States, residing at Plainfield, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in Trusses, of which the following is a specification.
The object of my invention is to provide a compact, simple, and durable structure by means of which any required adjustment and pressure may be obtained.
To this end the invention consists Vin certain combinations of devices hereinafter described and claimed.
In the accompanying drawings, Figure l is a View in perspective showing a complete truss with the band or frame inclosed in a iieXible girdle or strap, as usual. Fig. 2 is a side elevation; Eig. 3, a section on the line 3 3 of Fig. 2, and Fig. 4L is a section on theV line 4401? Fig. 3.
The band or frame may consist of a curved solid corrugated piece of metal A, formed with two arms A A' at the pad end. As will be seen from Fig. 2, the part A A of the band is formed by heavy pieces of wire secured at a in a concave face of the solid part of the band A, from which theyproject, constituting a straight prolongation of the band. The parts A are connected at the ends by across-piece A2 by means of screws, as shown. This affords a light and sufficiently rigid structure for the purposes of my invention.
As indicated in Fig. 3 by the dotted lines A3, the entire band may be formed of sufficiently heavy wire bent into the desired shape, as shown. On and between the two sides or arms A A of the band is mounteda block or frame, which, as shown, consists of a straight central part B, a projection therefrom on one side (marked B) perforated for the passage of the side A of the band, to which it is secured by a set-screw, and two similar projections 132 at each end at the opposite side of the central portion, also perforated to receive the other side A of the band, to which they are respectively attached by set-screws, as shown. This frame-piece firmly unites and embraces the two arms of the band.
Between the two projections B2 and around the arm A' of the band is arranged a springserial N6. 592,557. (No model.)
barrel C, a spiral spring D, and a spring-ath justing nut E. As clearly seen in Fig. 4, the spring surrounding the arm A of the band and enveloped by the spring-barrel has one end attached to the solid head of the springbarrel and the opposite end to the hub of the nut, which projects into the open end of the barrel, and upon which the barrel has its bearing at that end.
The nut E is shown as formed with square polygonal sides and apertures e for the application of a suitable key or wrench to wind up the spring and is held by a spring-catch, which may consist of a leaf-spring F, bolted upon the central part B of the frame and carrying a pin f, projecting through an opening in the frame and engaging the apertures e in the adjusting-nut.
The spring F maybe held up while the nut is being manipulated. The spring-barrel has secured to it or cast with it an arm G, extending obliqucly therefrom and upon which the pad Il is mounted. This arm is formed with a shoulder g, Fig. 3, which abuts against the edge of the frame-piece B, as at g', and limits the inward movement of the pad under the strain ofthe spring, as clearly shown by the dotted lines in that figure. The pad is of the usual shape and is attached to the arm G by a screw h, which when loosened may form the pivotal point for the adjustment of the pad in the following manner: The end of the arm, G has therein an elongated segmental slot 7i', referable to the center h, in which a set-screw engaging the rear face of the pad works.
The belt or girdle may be applied as indicated in Fig. l, and serves to prevent contact of the metal with the person. The pressure of the pad is an inward and upward one, which is most desirable in many cases.
The frame B B B2 and related parts may readily be adjusted to any position 'on the arms A A of the band shown in Fig. 2, or, what is the same thing, upon the wire sides or arms of the band when composed of wire, as indicated by the dotted lines A3 in Fig. 3.
l. The combination, in a truss, of the band having the parallel arms, the frame mounted upon and between said arms, the spring-barrel, spring and adjusting-nut mounted upon IOO one of the arms between the ends ot' the frame,
A and a pad carried by the barrel substantially as set forth.
2. The combination of the band having the arms A A, a detachable Cross-piece Connecting the ends, the frame mounted upon and between the two arms, the spring-barrel, spring and adj Listing-nut mounted upon one of the arms between the ends of the frame, the spring detent or eateh mounted upon the frame, and the adjustable pad carried by the spring-barrel, substantially as set forth.
3. The Combination of a band, a frame mounted upon and between the two sides of the band, a spring-barrel and spring oontained within the barrel mounted between the projecting ends of the frame, means for
