16 Claims.

This invention relates to railway rolling stock and consists in a novel safety guard for brake bottom connections.

The main object of the invention is to provide a simple and efficient bottom connection safety guard which is associated with the means for securing a brake beam guard, guide or supporting strap to a truck part.

Another object is to provide means for yieldingly resisting rotation of the bottom rod guard and which tends to return the guard to its normal position in case the guard is struck and tilted by an obstacle between the rails.

These objects and others are attained by the structures illustrated in the accompanying drawings, in which- Figure 1 is a perspective view showing portions of a railway truck and brake rigging.

Figure 2 is a detail view showing a modified bracket for securing the guard, guide or supporting strap to the spring plank.

Figure 3 is a view of a modification of the bottom rod guard.

Figure 4 is a detail vertical transverse section through the spring plank and showing another modification of the guard.

Figure 5 is a vertical longitudinal section through the guard, guide or supporting strap and illustrating another form of bottom rod guard.

Figure 6 is a detail view corresponding to Figure 5, but showing the bottom rod guard in tilted position.

Figure 7 illustrates another modification.

Figure 8 illustrates still another modification.

In Figure 1, a spring plank l of usual channel form has a bracket 2 secured to the lower surface 7 thereof by means of rivets 3. The brackethas a recessed top web 4 and depending flanges 5 having holes 6 receiving pins 7 which detachably secure the brake beam guard, guide or support strap 8 to the bracket. The brake rigging illustrated comprises a truss-type brake beam including compression and tension members 9 and 10 and a strut l1 pivoted to brake lever 12, the brake lever being pinned at the bottom to a bottom connecting rod 13. Ears 14 onthe front end of strut 11 mount a chair 14a which engages strap 8.

Each pin 7 includes a hooked portion 15 de pending from the bracket 2 and extending beneath the adjacent bottom connection 13 and forming a safety guard for the bottom connection. 1

In Figure 2, the spring plank l'lhas depressions 18 in the horizontal web which are perforated to receive the legs of one or more inverted U-shaped brackets 19. The brake beam guard, guide or supporting strap 16 is secured between the legs of bracket 19 by pins 20, each having a. hole 21 at one end for a cotter key, and a hooked portion 22 at the other end extending beneath the bottom connection 23 and forming a safety guard therefor.

In Figure 3, pin 24 has one end extending between the flanges 25 of the brake beam guard, 5 guide or support bracket 26, adepending sidewardly disposed portion 2'7 extending beneath the bottom rod 28, and a flattened portion 29 at the other end secured to spring plank 30 by a rivet or bolt 31. In this form the bottom rod safety guard is more securely fastened and is more rigid than those illustrated in Figures 1 and 2, and, in case of loss of a brake lever pin, the bracket 26 is relieved of much of the weight of the connecting rod. The end of the 75, loop 27 may be hooked over the upright flange of the spring plank, as indicated at 46 in Figure 4. This form of engagement of the safety guard with the spring plank facilitates assembly and disassembly in case parts of the brake rigging or the guard, itself, are replaced. The loo-p 32 may be further secured to the spring plank 33 by a bolt or rivet, if desired, the latter being indicated at 34.

In Figures 5 and 6, the resilient guard, guide or supporting strap 35 is slightly distorted in assembling with bracket 36 in order to prevent rattling. Pin 37 has a flattened surface 38 (see Figure 6) between the flanges of bracket 36 for engaging strap 35. The yielding pressure of the strap 35 against this flattened surface increases the resistance of the pin to rotation. Moreover,

if the looped end portion 40 of the pin is struck by an obstacle in the track and tilted, as shown in Figure 6, the pin will tend to return immedi- 95. ately to its normal position.

' In Figure '7, a guard, guide or supporting strap 41 is detachably secured to a wrought type of supporting bracket 42 by a straight pin 43.. The pin at the head end mounts a bent 0. strap or loop 44 which extends beneath the bottom connection 45 and is secured to spring plank 39 by a rivet 50.

In Figure 8, the pin 47 has a closed loop 48 at one end which encircles the bottom connection 49. Thepin could be squared at the head end and a separate loop provided, similar to the element. 44 in Figure 7.

In each of the figures, the brake beam guard, guide or support members illustrated and their supporting brackets are of the types now generally in use, and in each of the forms, except that shown in Figure '7, the looped pin replaces the pin ordinarily used to detachably secure the brake beam guard, guide or support member to the bracket. This bracket might be secured to, or formed integral with, a truck member other than the spring plank, such as the bolster, a convenient transom, or an arm on the side frame. The device has fewer parts than other devices at present used for accomplishing a similar purpose and is, accordingly, less expensive and more durable.

Obviously, various details of the structures illustrated might be varied within the spirit of the invention and the exclusive use of all such variations as come within the scope of the appended claims is contemplated.

What is claimed is:

1. In combination, a railway truck part, flanges on said part, brake rigging including a bottom connection, a brake beam guard, guide or support member mounted between said flanges, and a pin-like element extending between said flanges and securing said member to said part, said element having an end portion extending beneath said connection and safeguarding the same.

2. A device for detachably securing a brake beam guard, guide or support strap to a truck part and including a movable pin having a depending hooked portion for safeguarding a brake bottom connection.

3. In combination, a railway truck part, a bracket on said part for mounting a brake beam guard, guide or support member, and a pin for securing said member in said bracket and having an end portion projecting beyond said bracket and forming a safeguard for a brake bottom connection.

4. In combination, a railway truck part, a bracket on said part for mounting a brake beam guard, guide or support member, a pin-like element for securing said member in said bracket, and structure carried solely by said element and disposed to form a safeguard for an adjacent brake bottom connection to prevent the connection from falling to the track upon failure of the lever attaching pin.

5. In combination, a railway truck part, a bracket on said part for mounting a brake beam guard, guide or support device, and a member for securing said device in said bracket and having an offset portion projecting beyond said bracket and forming a safeguard for a brake bottom connection, said member having a flat surface engaging said device to resist rotation of said member.

6.
