If desired, the chair may be applied to a vchan- Figure -9'is a sectioncorresponding toFigure 2 nel shape compression member, as indicated at but showing a different .form' of the invention 2] inFigure 3, the opposing faces of the body with the two parts hinged 'to each-other above and jaw having elements 22 and 23 respectively the vbeam. 1 arranged to engage opposing points on the com- '05 pression member to stably contact the same. Elements 22 and 23 are spaced from elements l8 and i9 previously referred to.
If desired, the chair may be applied to a brake beam compression member of T section, as indicated at 24 in Figure 4. In such application the leg of the T is received in a recess 25 provided in jaw H] and the cross arm of the T engages elements 26 on body 9 spaced apart sufiiciently to provide a stable bearing for the beam member but still close enough together to be received between the flanges of the U section compression member or the channel section comnression member.
The opposing faces of the chair body and clamping jaw may be further modified, as indicated in Figure 8, to seat and securely hold a beam member 35 of angle section. In this form of the invention the upwardly and downwardly facing elements at the top and bottom of the chair body 3| are recessed, as shown at 32, to receive the edges of the beam member. The corner portion of the beam may be received in a recess 25 which also receives the T leg, and the adjacent face of the jaw may be flattened at 33 to firmly seat the angle legs near the corner. This angle type of beam compression member is not being adopted on new beams at this time and it may be preferable to omit recesses 32 and flats 33 provided for the same so that the chair body and jaw elements which engage the beam compression members of different cross sections may provide for greater contact area. Figure 8 illustrates how the device may be shaped to accommodate four difiierent sections of beam members. It will be understood that the chair parts may be shaped to seat diiferent beam members of similar section but of different dimensions.
Figure 9 illustrates a form of the invention in which the upper parts 35 and 36 of the body and jaw are extended towards each other to overlap and to receive a hinged pin 31 while the lower portions 38 and 39 form spaced ears for receiving the clamping bolt 40.
With the arrangements previously described, loosening of the nut will not affect the assembly of the device but if the nut should work off of the bolt and the bolt work out of the jaw parts, eventually the hinged portion of the chair would drop backward and downward and permit the chair to work away from the brake head and then drop off. This could not happen with the two parts hinged to each other at the top of the compression member. as shown in Figure 9.
With this construction the bolt receiving ears project downwardly from the beam a greater distance than the hinged lugs in the other forms of the invention. To provide clearance between the beam clamping parts of the chair and the supporting bar M, it may be necessary to extend the latter downwardly and place an extra bend in the same, as indicated at 42 to avoid any change in the mounting of the bar upon the spring plank 43 or other truck parts to which the bar is attached. However, this additional downward extension of the bar may not be required. in which case the contour of the bar would be the same as shown in Figure 2.
Figures 10 and 11 illustrate more clearly than is illustrated in Figure 1 how the body portion of the chair securely engages upwardly, downwardly and outwardly facing portions of the beam tension and compression members to hold the assembled parts against movement along the beam. The inclined elements 45 and 46 resist movement of the chair towards the brake head irrespective of contact between the beam and the chair jaw member ID. Movement of the chair away from the head is prevented by elements 4! and 48 inclined in the opposite direction. If the chair is mounted on the other end of the beam then the functioning of elements 45, 46, 41 and 48 would be reversed. The lip 49 at the upper end of recess 20 overlies the top of the beam tension member and not only helps prevent movement of the chair along the brake beam but it prevents the accidental pulling away or dislocation of shoe [4 in the handling of the brake beams.
Each application of the chair indicates metal to metal contact between the same and the beam members, but it will be understood that inserts of rubber or other packing material may be placed between the contacting metal parts to break up vibration and avoid loosening up of the clamping bolt nut. Inserts of this type are illustrated in Patent 2,067,596 issued to the present inventor January 12, 1937, but such inserts are not essential to the present device and are omitted from the drawings to avoid confusion.
The details of the chair may be varied without departing from the spirit of the invention and the exclusive use of such modifications as come within the scope of the claims is contemplated.
