The obj ects' and advantages of invention will'be re'ajdily' comprehended from the" detailed description of the accompanying drawing; wherein; 1

' The "ejinbodif "ent of the invention as shown in the" first four' figures of the dra wing is especially adapted for use in connection with the @611 lniions' o r. clds'e'd link type of brake hanger; a part ivhe'r'eof, is shown at 10. The

truck frame 11 is preferablyprdvidedwith a projection or arm '12; the outer end whereof isienlar edlaterally orderfto permit the" same tebe slotted orlsocketed, therebypizoviding the' upper and lower walls 13 andlt -respectively, connectedfat their inner ends by the vertical ebs 15, which are preferably.

made arcuate asshown in dotted lines at 16 p in Figure 2 in order to conform with; the arouate surfaces 17, 17, adjacent the ends of the keeper blocks 18. The slot or socket in the end of the arm 12 is preferably made at "a slight inclination as moreclea'rly shown in Figure 2, so as to induce the keeper means to slide downwardly with the rounded portions 17 17 seatedion the arciiate webs 15. It is apparent from this construction that acoidental vdisplacement of the keeper means, in the event of loss'of the locking means, is; less likely, while at the same time the strains placed on the keeper means will all be transmitted to the truck frame ,The keeper means consists of a pair of blocks identical to that shown. in Figure 4;

each preferably provided with the projection or shoulder 19,- int'ermediate of the arcuate snrfaces,17,'17 on the inneror .rear'side of the blocks. These shoill'der's are intended to extendrinto the recess 20 in the arin inter-I mediate ofthe webs 15, 15, and thereby prevent shifting of the keeper means in a direction lengthwise of the blocks. Each block 18,

on its apposite face is provided with the longij tudinally disposed groove 21 intended to receive the upper end of thebrake hanger 10;

the grooves 21 ofcthe two-blocks, when arranged in face to facecrelatlon as shownrin Figure 2, being SUfilClIlfi .to receive the-link lO a nd stillzvpermitzfree oscillation of the link -when'the blocks are in jiixtapositionf The upper ahd-lovver-I walls 13 and 14 are each provided with a slotdispo'sed at right i anglest-o the. main portion of the arm 12;

that is to say the slots extend, lengthwise of the socket; The slot 22 in the Upper wall 13 is somewhat longerthanthe slot 23 in the lower wall l lyand the inner 'en'd'sto f both slots are made sloping outwardl or forward 1y toward the bottom at: an angle substan tially similar to the angle ofinelination of thekeeperblocks.

These slo'tsl22 211 16123are'soparrangedthat' the inner ends thereof will be; disposed in a vertical planerearward of the forwardedges" of the keeper elements when 'the" latter" are completely seated in the socket formed in the arm 12, see Figure 2. The forward longitudinal sides of the keeper members 18 (which are arranged in superposed relation) are each provided with a vertically disposed groove or slotas shown at 24, see Figure 4, for'the purpose of receiving the rear edge of the wedge member or key 25 when the latter has been driven through slots 22 and 23 in the arm portions or walls 13 and 14. The forward longitudinal edge of the wedge member or key 25 is intended to be disposed perpendicular to the ends of the wedge member while the rear longitudinal edge is made sloping so as to provide a key member tapering toward the lower end thereof. 1

In practice, the brake hanger 10 has its upper end inserted into the groove 21 of the lower kee er member or block 18; the upper block 18 is then put into position with its grooved face downwardly so that the grooves 21 of the two blocks constitute a suitable channelfor the upper end of the hanger 10. The assembled elements are then inserted into the socket formed between the upper walls 13 and 14, with the shoulders 19 disposed into the rear end of the socket intermediate of the vertical webs between walls 13 and 14. 1 These shoulders not only center the blocks in proper position, but also prevent lateral or sidewise movement thereof. The key membar or Wedge is then driven into place with its tapered'end disposed downwardly thus causing the forward perpendicular edge to be in'bearing relation with the forward ends of the slots 22 and 23 while the sloping rear edge of the key member, which is disposed in the grooves 24 of both blocks, will be in hearing relation with the forward surfaces of the blocks, without contact at the rear ends of the slots 22 and 23. This causes the blocks to be firmly wedged in place. It is understood. that the hanger '10 straddles the lower wall portion 14. After the key has been firmlyadriveninto place, the lower end thereof preferably flexed orbent laterally as shown at 26 in Figure 1 so that accidental removal of the key is prevented.

. In Figures 5 and 6, I show a modification especially intended for use in connection with the U-shape hanger indicated at 27 having upper eyeletted ends 28 to receive a supportingpin 29. The keeper means, in this instance, consists of a pair of corresponding blocks 30, 30 of somewhat greater length than the blocks or keeper members 18. The ends of blocks 30, 30 are preferably slightly enlarged as shown at 31 and slotted transversely from the rear sides to receive the eyeletted ends 28 of the hanger 27 and still permit oscillatory movement of the hanger. These slotted ends are disposed beyond the vertical webs 15, 15 of the arm 12 whereby the upper and lower walls 13 and 14 are connected to- --gether. .The appositefaces of each member or block 30 is provided with a longitudinal groove disposed throughout the intermediate or main body portion as well as partially into the ends to receive the supporting pin 29. The pin receiving grooves terminate a short distance from the immediate ends of the blocks so as to provide the abutting walls 32,, 32 at the ends of the pin 29 and thus prevent longitudinal movement of the latter. V

. It will be'understood that the keeper mem bers or blocks 30 are identical in construction and like blocks 18 are interchangeable. That is to say, either block may constitute the upper or lower block. The forward longitudinal sides of the blocks 30 are each provided at a registering point with a vertically disposed groove 33 adapted to receive the wedge member or key 25 when the latter is disposed through slots 22 and 23 formed in the upper and lower wall portions 13 and 1 1 like in the previously described construction. The wedge member 25, for the construction shown in'Figures 5 and 6, as well as the function of the slots 22 and 23 are identical with that previously described.

In practice, the supporting pin 29 is inserted through the eyelets 28 of hanger 27, the pin 29 then placed in the longitudinal'groove of the lower block 30 after-which the upper block 30' is placed thereon with its longitudinal groove encircling the upper side of the supporting pin; the end walls 32 of both blocks completely closing the ends of the groove and preventing movement of the pin. The assembled elements are then put into the socket in the arm intermediate of the walls 13 and 14 with the hanger 27 straddling the lower wall portion l tlike in the previously described construction. The wedge member or key 25 is then driven downwardly through the slots 22 and 23 with its rear sloping edge in the grooves 330i the keeper members or blocks. The slots 22 and 23, as previously described, are of such length that their rear ends are disposed in avertical plane rearward of the vertical forward longitudinal edges of the keeper elements or blocks so that the wedge member or key will-not contact with the rear ends of the slots 22 and 23. This permits a firm wedging of the keeper blocks in place. The lower end of the wedge member or key is then preferably flexed or bent laterally as shown vin Figure 5 at 26 to hold the wedge member firmly in place.

It is apparent that other means may be used for locking the wedge'member in place, but the method shown is believed to be the simplestand most acceptable, because the necessity for employing additional parts or elements is eliminated. v p

With my constructions it is apparent that if any wearshould result between the keeper members or blocks and the cast'metal portions of the truck frame, .this can :be readily.

taken up by adjustment or further driving of the wedge member into place. Furthermore, the wedge member or key when properly driven home will prevent all chatter or vibration between the keeper member and the truck frame and thus materially reduce possibility of wear. Furthermore, with'my improved construction, a considerable saving in material and expense is possible because the method of securing the keeper means in place enables narrower keeper blocks to be employed than has heretofore'been'the case.

In order to permit the temporary use of an ordinary brake pin or bolt, in the event of loss of thewedge key while the train is at a distance from the shops, I show the intermediate portions of slots 22' and 23 in the upper and lower walls 13 andM, bowed outwardly or made arcuateas shown at 34 to provide an opening sufficiently large to receive the ordinary round pin which is generally accesible along the ri ht-of-way. The slots 2% in keeper blocks or plates 18,'and the slots 33 1 in the keeper plates 30, at the outer ends, are

therefore flared outwardly in an arcuate' manner as shown at 35 and 36, respectively, see Figures l and 6, to permit the temporary use of an ordinary bolt or pin having a round shank. It is apparent that the round pin will hold the keeper elements with the brake hangers in proper position, permitting proper brake application during the remainder of the run, until a replacement of the Wedge-'- key can be made.

The constructions shown are thought to be the simplest and best embodiments of the invention, but certain modifications may be made without, however, departing from the I combination wlth a truck frame havlng a spirit of my invention;
