A-p'plication filed May 15, 1924-. Serial No. mass.

To allwhom it may concern;

Be it known that I, BRonE'RreK I-LisKnLL. residing at Franklin, in the county oi? v'enango and. State of Pennsylvania; a

citizen of the United States, have inrvented or discovered certain new and useful Improvements in Brake-Befaln- Sup ports, of which in'rprov'ements the following is specification.

Itis thegeneral practice to employ a length of metal sufliciently long to extend across the truck element and under both brake beams. claimed herein relates to certain improvements in the manner of attaching what mightbe termed independent or individual brake beam supporting rails to a truck element. The inventionishereinafter more fully (IQSOI'lbECl' and claimed.

1, 1, have their outer portions 2, which underlie the tension member 3 of a truss brake beam, upwardly inclined, and their inner ends firmly secured to the flanges 4-. of the spring plank, which may be formed by a channel as shown in. Figs. 1 and 2, or by angle bars as shown in Fig. 3.

In the construction shown in Figs. 1 and 2 the inner end of portions of the rails are provided with shoulders 5 and 6 and spaced distances apart substantially equal to the thickness of the flanges 4, 43*. flanges are formed openings 7 into which are inserted the ends of the rails to such position that the shoulders 5 will be inside of the flanges. Before inserting the inner ends of the rails. one end of abar 8 is inserted through the openings in one of the flanges as 4 sufliciently far to permit of the opposite end being pushed down inside the other flange to a point below the opening 7 in the flange 4. The inner end of the rail 1 is then inserted in the opening in the flange 4 and the bar 8 is shifted longi- The invention described and In the accompanying drawings forming a In the practice are the invention the rails.

rig-ht hand end: thereof is withdrawnfrom the opening 7 in the flange P. The inner end of the rail l is then inserted into said opeiiing and the bar shifted to the right, the end of the bar passing'under theend of the rail and raising it until the shoulders 5 and 6 are in position on opposite sides of t flange 4i 1*" n Fig; 1 the bar 8 is made of such a: length relative to the r-ldth of the spring plank that the e'ridportionswill extend suflioient distances beyond the sides of the plankto serve as; vertical resilient supports for the rails. Provision is made for lockingthe bar 8- as against longitudinal movement after it has been placed inposition? as above? described. l-Vhileany suitable" ineans' may employed for lockingthe bar the device showirfconsisting of a cotter pin 9 passing throu-o'h the bar andtheweb of the spring'pl ank, has been found suitable.

In-the construction shown in 3Qopjen= inc s T re formed in? the flanges 4s anda as a e d for the reception of end portions of the rails 1 and 1 and the bar 8. In lieu of so constructing the rails so as to engage the flanges of the plank, the rails and bar 8 are so constructed as to interlock one with the other. Such interlocking can h effected by forming a projection or a shoulder on one element and a depression or recess on the other elements for the reception of the rojection or shoulder. In the construction shownherein the portions of parts in such relation that except under ab-- I normal conditions they will remain inter locked. i

In congregating the parts, the bar 8 is first placed. in position then the inner ends of the rails are inserted through the opening in the flanges and moved longitudinally until the projection on one part enters the depression in the other part, the resiliency of the rails and bar permitting of the movement of one part on the other until interlocking has been effected. It is preferable to ensure the interlocking of the parts by means of links 12 adapted to surround the parts preferably in line with the interengaging depressions and projections. The links are placed on the rails before they are placed in position and then slid along to locking position after the rails have been adjusted.

Suitable means are provided for preventing accidental longitudinal movements of the rails and bar, as for example, by means of shoulders adapted to engage the flanges. In the construction shown, such shoulders 13 are formed by the metal displaced in forming the depression or recesses 10 in the bar 8, but as the rails are interlocked with the bar 8, it is immaterial whether the shoulders 13 are formed on the bar or rails.

From the foregoing disclosure of its construction, arrangement and manner of assembling and operating the device. it Will be seen that all of the objects and advantages recited in the statement of invention have been fully and e'lficiently carried out and while the preferred forms or modifications of carrying out the invention are shown and described herein, other forms or modifications will readily suggest themselves without in any way departing from the present invention.

I claim herein as my invention:

1. The combination of a flanged spring .plank having holes through the flanges,

beam supporting rails having their inner end projecting through said openings and means for locking the rails in position.

2. The combination of a flanged spring plank having holes through the flanges, beam supporting rails having their inner ends projecting through said openings and means for locking the rails in position and means for supporting the rails vertically.

The combination of a flanged spring plank having holes through the flanges, beam supporting rails projecting into said holes and provided with spaced shoulders adjacent to their inner ends and means for shifting the ends of the rails laterally to cause the shoulders to bear on opposite sides of: the flanges.

4. The combination of a flanged spring plank having holes through its flanges, beam supporting rails having their inner ends projecting into said holes and provided with spaced shoulders adjacent to their inner ends and a bar extending across the plank and passing under the inner ends of the rails and holding such ends in position Where the shoulders o the rails bear on opposite sides of the flanges.

5. The combination of a flanged spring plank having holes through its flanges, beam supporting rails having their inner ends projecting into said holes and provided with spaced shoulders adjacent to their inner ends and a bar extending across the plank and passing under the inner ends of the rails and holding such ends in position where the shoulders of the rails bear on opposite sides of the flanges, the outer ends of the bars supporting the rails adjacent to opposite sides of the plank.

In testimony whereof I have hereunto set my hand.

BRODERICK HASKELL.
