SHOE FGR BRAKE-BEAM SUPPORTS.

Application filed. May 15,

To (ZZZ whom it may concern:

Be it known that I, l VILLIAM E. FOWLER, J11, residing at Mount Lebanon, in the county of Allegheny and State or" Pennsylvania, a citizen of the United States, have invented or discovered certain new and useful Improvements in Shoes for Brake-Beam Supports, of which improvements the 'following is a specification.

The invention described herein relates to certain improvements in shoes for supplemental supports for brake beams, the improved shoes being especially adapted "for use in thattype of supports where the points at which the beam is supported are located intermediate the ends of the beam and the strut, such type being generally known in the art as four point supports. These supple mental supports consist of shoes or carriers interposed between the tension member of the brake beam and rails secured to the spring plank and extending on both sides of the plank below the brake beam. 'As the portions of the tension member engaging the shoes or carriers are oppositely inclined, it

has been necessary to make the shoes rights and lofts.

The object of the invention described herein is to provide shoes which can be applied to either portion of the tension member. The invention is hereinafter more fully described and claimed;

In the accompanying drawings forming a part of this specification, Fig. 1 is a plan view showing part of the spring plank, strut, brake beam and supporting rails for four point supports and my improved brake shoe in position on the rails; Fig. 2 is a top plan view of the improved shoe; Fig. 3 is a side elevation of the same; Fig. 4 is a sectional elevation; Fig. 5 illustrates a modification of the construction of the shoe; and Fig. 6 is a sectional elevation illustrating a modification in the manner of mounting the saddle on the body portion.

The improved shoe consists of a body por-- tion 1 having a slot 2 therethrough for the reception of the supporting rail 3 which is adapted to be secured in any suitable man ner .to the spring plank of the truck. On this body portion a saddle having a seat or hearing 5 for the tension member of the brake beam, is rotatably mounted, said parts being held as against accidental separation 1924. Serial in). 713,560.

while in use by an axial member as the pin or rivet 8; In order to relieve such pin,in part at least, of lateral strain, one ofthe members, as for example the body portion 1 of the shoe, is provided with a projection 6, preferably conical, and adapted to engage a complementary seat or hearing in the other member. As the seat or hearing for the tension member is U-shz'iped or open-topped, a shoe can readily be placed in position by sliding it onto the supporting rail, turning the saddle so that its axis will be parallel with a portion oi the tension member and lowering the brake beam until the tension member is seated in the saddle. In order to permit of the insertion of-the pivotal pin 8, an opening 9 is formed in the under side of the body portion, as clearly shown in Figs. 3 and 4. In the construction shown in Figs. 2, 3, and 4;, the body portion is so constructed that the sides of the saddle 5 will beat right angles to the face oi": the inclined portions of the supporting rails, but if it is preferred that the shoe should be directly in line vertically with the tension member, the body portion may be shaped as shown in Fig. 5, in which case the sides of the saddle will be at angles to the faces of the inclined portions of the rails equal or substantially equal to the inclination of such portions. Vi hen employing constructions shown in Figs. 2, 3 and 4, the legs of the saddle should be formed somewhat lon er than is necessary in the construction shown in Fig. 5, in order to insure that the inner leg, when the shoe is in position on the tension member, should extend up sufiiciently high to insure the movement of the saddle along the rail as the brake beam is shifted to apply the brakes.

In lieu of employing a removable pin for connecting the saddle and body portion, one of said members as the saddle may be made with an axial boss centrally arranged within an annular flange 11 formed on the saddle. The walls of the annular space formed by the flange 11 and boss 10 form the socket for the annular projection or ring 6 on the body portion of the shoe, the boss 10 pro jecting through such projection as shown. The annular projection or ring (i has an internal diameter substantially equal to the diameter of the boss and overhangs the open it will project suitable distance below the projection or ring to permit or its being headed, the enlargement due to such heading extending under the projection or ring and lying wholly in the opening or recess 12. I claim herein. as my invention: 1. A shoe for a supplemental support for a brake beam consisting of a body portion slotted for the reception of a supporting rail and a saddle for the reception of the tension member of a brake beam, said saddle being pivotally mounted on the body portion.

2. A shoe for asupplemental support for a brake beam consisting of a body portion slotted for the reception of a supporting rail, a saddle, one of said parts being provided with a projection and the other with a socket for the reception of the projection, the projection and socket being so constructed that the saddle may rotate on the body portion.

8. A saddle for a supplemental support for a brake beam consisting of a body portion slotted forthe reception of a supporting rail, a saddle, one of said parts being provided with a projection and the other with a socket for the reception of the projection, the projection and socket being so constructed that thesaddle may rotate on the body portion, and means for holding the saddle in position on the body portion.

4. A saddle for a supplemental support for a b ake beam consisting of a saddle pro vided with a central boss, at body per ion slotted for the reception of a sup portingrail and having an undercut opening throa h the upper wall of the slot for the reception or" the boss on the saddle the lower portion 01" the boss being); extended under the contract ed portion of the hole through the wall of the slot.

5. A shoe for a supplemental support for a brake beam consisting of a saddle having a seat for the reception of the tensi ber the brake beam and provided a socket and having a boss projecting centrally through the socket, a body portion slotted for the reception of the supporting rail and provided with an annular projection adapted to extend into the socket in the saddle, the boss on the saddle being adapted to extend through the annular project on and so headed as to engage such projection.

In testimony whereof, I have hereunto set my hand.
