Application and my s, 1924. seriai No. 724,803.

To all ywhom t may concern:

Be it known that I, IVILLAM E. Fowi'ina, Jr., residing at Mount Lebanon.v in the county ot' Allegheny and State of Pennsylvania., a citizen of the United States, have invented or discovered certain new and use- :tul Improvements in Securing Brake-Beam Supports to Spring Planks, of which improvements the following is a specification.

In an application tiled May 15, 1924, Se rial Number 713,561, is shown and described means tor so securing a brake beam sup-` porting rail to the spring plank oit a car truck that the rail will have a resilient bearing at two points on the underside ot' the plank, and a resilient bearing on the upper face of the plank, the latter' point of bearing being intermediate the other two points. In the construction shown in said application, a loop is so formed in the rail approximately midway of its an opening in the plank. opposite sides of the loop, the rail bears directly on the underside of the plank and the portions ol the rail betweenthe loop and the points of bearing curve downward out of contact, andthe loop is made ol such a length. relative, to these curved portions that the loop cannot be passed throughan opening` in the spring plank sul'liciently lar to permit ot a supporting pin to be passed through the loop without flexing and placing undert-ension the downwardly curved portions intermediate the loop and the points where the rail bears on the underside of the plank.

The invention described herein relates to a modification ot the construction above de scribed.

In the acompanying drawings forming a part of this specilication Fig. 1 is a plan view showing a portion of a spring plank and a rail for supporting the brake beam secured to the springplank `as hereinafter described and claimed; Figs. 2 and 3 are sectional views on planes indicated respectively by the lines II-II and `III-III, Fig. 1.

In the practice ol? the invention the supporting rail extends across the spring plank length asv to be capable ot being passed through At points on 1 and projects suliicient distances on each side thereof as to underlie the tension members 2 of the brake beam. Wvhen in operative positions, the tension members 2 restin seats 5 in shoes 4 which are movably mounted on the rails. In order to facilitate the movements otI the brake beams away from the wheels7 the outer portions of the rails are inclined as indicated at S. Suitable stops 3a are provided to prevent.accidental movement ot the shoes from the rails.

As shown, the supporting` rail is arranged under the spring plank and the intermediate portion of the rail is so bent that the rail will ybear on the. underside of the plank only at points adjacent to the edges ot the plank as indicated at G. The means employed tor suspending the. rail from the plank at a pointvl interniediate the bearing points or seats 6 are so constructed that the portions intermediate the seats are flexed and placed under tension before the rail can be connected to the plank. Inthe construction shown `herein the suspending means consists ot a link 12 through which the rail is passed and a key or pin 10 adapted to be passed through the upper portion of the link when the latter has been passed through an opening 9 in the web: of the spring plank. As will be seen in Fig.` 2, the portion 8 intermediate the bearings'or seats 6, .is separated a substantial vdistance 'from the-underside ot the plank and the link is made of such a length that 'it cannot pass through the opening in the plank sulliciently liar to permit ot the insertion of the key or pin without deflect-ing the portion 8 from normal position. As the rail is made of resilient material, the tlexure o'l the portion 8 will cause the seats together with the link 12 to bear resiliently on the plank vand the pin 10' respectively.

vWhile any suitable means may be einployed to prevent material longitudinal movement of the rail, it is preferred to so ol'set-*a portion ot the rail as to form a recess or seat 7 for the reception ot the ring or link. A desirable means for preventing a movement ot the pin or key as will permit of the dropping o'l the link.` consists in forming a projection 13 on the underside of Sii the key adapted when the latter is in operative position to projeot into the opening 9 in the spring plank.

I Claim herein as my invention:

l. The combination of a spring plank of a Car truck having an opening therethrough, a supporting rail, a link surrounding the rail and extending through the opening in the plank and means passing through the portion of the link projecting above the plank and hearing on the upper side of the plank for supporting the link.

2. The combination of' a spring plank of a ear truck having an opening therethrough, a supporting rail having spaced points of hearing on the underside of the plankr` a link surrounding thel rail at a point intermediate the points of hearing on the plank and projecting through the opening in the plank and means passing through the portion of the link projecting through the opening and bearing on the plank for supporting the link.

3. The combination of a spring plank el a ear truck having an opening therethrough, a supporting rail having spaced points of hearing on the undersides of the plank and having a seat or offset intermediate. such spaced hearing points, a link surroinnlingthel rail and engaging the seat or offset therein and projecting through the opening` in the plank, and means passing through the portion of the link above the plank and hearing on the plank for supporting the link.

In testimony whereof, I have hereunto set my hand.
