This invention relates to railway brake beam 11 Claims.
tion of the frame member.
Another object is to cheapen the frame member by eliminating the bracket or arm used in previous structures for facilitating mounting of the fourth point support or safety guard.
These objects and others are attained by the structures illustrated drawings, in which in the accompanyin Figures 1 to 3, 5 to 8, 10, 11, 13, 14, and 16 are vertical transverse sections through truck side frames illustrating various forms of the invention applied thereto.
Figure 4 is a view in perspective of a detail of the form in Figure 3.
Figure 9 is a side view of the structure shown in Figure 8.
Figure 12 is a detail section taken substantially on the line l2l2 of Figure 11.
Figure 15 is a horizontal section through a truck side frame and illustrates another form of the invention.
In each of the figures, except Figure 16, the invention is illustrated as applied tothe lower chord of a truck side frame casting of familiar construction, only the part of the frame to which the guard, guide or support bracket is attached being illustrated.
The frame includes a bolster spring seat I having a hollow box section portion beneath the same including side walls 2 and 3 and a bottom wall 4, see Fig. 1. Side walls 2 and 3 are provided with alined perforations which receive elongated boltlike portion 5 at the outer end of a sidewardly ex tending arm 6 on the bracket I which mounts the brake beam guard, guide or support member 8 by means of pin 9. The bolt-like portion 5 is threaded for nuts Hi and I I which engage the outer surfaces of walls 2 and 3 and maintain the bracket 1 and the guard, guide or support device in the proper position on the side frame.
In Figure 2, the spaced side walls l2 and i3 beneath the bolster spring seat H! are perforated at l5 and I6 for receiving the outer portion ll of the sidewardly extending arm is on the guard,
Portion I! at its outer extremity includes depending legs 20, the outer extending along the outer surface of wall !2 and the inner extending through a perforation 2! in the bottom wall 23 of the side frame. Legs 23 receive pin 22, which abuts the bottom wall, 5 for maintaining the bracket in position. Perforations [5 and 16 are elongated transversely of arm l8 to permit the insertion or removal of legs 20 when the arm is turned ninety degrees from the position shown. An enlargement 24 is pro- 10 vided for abutting the inner surface of the wall In Figure 3, the sidewardly extending arm 25 on the guard, guide or support bracket extends through perforations 26 and 2'! in the side walls 15 of the frame member and has a. lug 28 and a hooked end 29 abutting the outer surfaces of the side walls. A U-shaped clip 30 rests upon a portion of arm 25 between the frame walls and the legs thereof depend through suitable perforations in the bottom wall 3| and receive a holding pin 32.
Perforations 2B and 21 and the'hooked end 29 are shaped similarly to perforations l5 and i6 and legs 2!, respectively, in Figure 2 to accommodate insertion and removal of the bracket upon rotation of the bracket ninety degrees from the position shown.
In Figure 5, perforations 40 in the spaced side frame walls are provided with sidewardly extending perforated lugs 41 which receive pins 42 for securing the bracket arm 43 in position. A finger 44 depends from the portion of arm 43 inwardly of the side frame and curves beneath and abuts the bottom wall 45 of the frame. This 35 finger serves to relieve the arm 43 of bending forces caused by the weight of the guard, guide or support bracket.
In Figure 6, the bracket arm 33 extends through perforations 34 in the side walls of the frame member and has a hook 35 at the outer end engaging the outer side wall and has a depression 36 between the walls which receives a pin 31 mounted in a bracket 38 projecting from the bottom wall 4 39 of the frame. 5 r
In Figure '7, the bracket arm 46 is held in position by means of an enlargement 41 abutting the inner side wall 48 and a pin or key 49 secured between bifurcations 50 at the outer end of the arm by a cotter 5|. 50
The bracket arm in Figure 8 is similar to that in Figure 7 except that an enlargement 52 is formed integral with the bracket arm 53 at the outer extremity and the perforations 54 in the spaced side walls of the frame member are made 55 large enough to receive the enlargement 52 when the bracket 55 is turned on its side, in the manner illustrated in Figure 9. Enlargements 52 and 56 abut the side walls of the frame, when in normal position, to hold the bracket in place.
In Figure 10, the bracket arm 51 is shown as extending through the inner wall 58 only of the side frame andenlargements 59 and 60 abut the surfaces of the wall for preventing tilting of the bracket. The bracket is turned 90 degrees, as in Figure 9, to permit insertion of the enlargement .60
through the perforation 61.
In Figures 11 and 12, the bracket arm ,62 has enlargements 63 and 64 for holding the bracket in position, and a bent flat spring 65 is applied to the arm inside the hollow side frame. Spring 65 engages the under surface of the bolster spring seat 66, and by forcing arm 62 against the lower edges of perforations in the spaced walls of the side frame, prevents rattling of the bracket.
Enlargement 64 is elongated vertically and the openings in the side frame are elongated hori zontally to permit passage therethrough of enlargement 64 when the bracket is rotated ninety degrees from the position shown, corresponding to the showing in Figures 8 and 9.
In Figures 13 and 14, other means of preventing rattling are illustrated. Figure 13 shows a spring 61 applied to the outer end of the arm 68 and compressed between the outer frame wall 69 and a washer 61a forming an abutment for the outer end of the spring and held in place by a key 61b. Enlargements I abutting the inner frame wall H limit the movement of the bracket arm. The inner enlargement corresponds in shape to the similar element 52 in Figure 8, and the opening in the left hand portion of the side frame is elongated, as opening 54 in Figure 9, to permit insertion and removal of the bracket arm. In Figure 14 the'inner enlargement 12 is spaced from a the inner wall 130i the side frame and a coiled spring 14 is compressed between enlargement l2 and the inner wall. The outer enlargement is passed through the openings in the side frame in the manner previously described for similar elementsin Figures 8, 11, and 13.
Figure 1 5 shows a one-piece strap-like member including inner portions for association with the brake beams and an outwardly offset intermediate portion 16 which abuts the wall 11 of the side frame. The strap is secured to the frame by means of a bracket device including bolts 18 extending through spaced walls 1! and 19, plates 80 being "provided to strengthen the connection.
In Figure '16, the guard, guide or support member 81 is shown carried from above by means of a bar 82 which extends through the portion 83 of the side frame above the bolster opening 64 and is secured in place by a pin or key 85. The bar .82 may abut the hanger bracket 86, and alug 61, shown dotted, provided to stabilize the guard or support. In this case, a wall of member t8 and the inner surface of bracket 86 constitute spaced parts of the truck side frame balancing the guard, guide or support bar 82.
In each of the forms, the guard, guide or support bracket is attached to a frame part without the provision of any rigid inwardly extending bracket or arm which would increase the cost of the truck frame and be liable to breakage. Moreover, in each of the forms, except that in Figure 10, the weight of the bracket is distributed between substantially spaced walls, the inner wall receiving downward pressure and the outer wall upward pressure due to the tendency of the bracket to tilt about the inner wall as a pivot. In the form shown in Figure 10, the weight of the bracket is distributed over a substantial portion of the single supporting wall.
The use of the novel supportbracket is not limited to the type of side frame illustrated, and in fact the attachment of a guard, guide or support device to another truck structural part, such as a transom or spring plank, would be facilitated by utilization of the novel features of the invention. The particular point of attachment of the bracket to'its supporting member is not essential.
,Any form of guard, guide or support member may be used and a resilient strap member may be provided-for engaging a chair depending from the beam, .or the device may be spaced beneath the beam serving only as a safety guard, or the beam maybe suspended from above in the manner illustrated in my co-pending application Serial No. 550,238, filed July 11, 1931.
