CHARLES F. HUNTOON, OF CHICAGO, ILLINOIS.
RUCK-BOLSTER.
Specification of Letters Patent.
Patented Jan. 2, 1151317.
Application filed July 3, 1916. Serial No. 107,313.
To all whom it may concern:
Be it known that 1, CHARLES F. HUN- TOON, a citizen of the United States of America, and a resident of Chicago, county of Cook, and State of Illinois, have vnted certain new and useful Impn'v'aacats in Truck-Bolsters, of which the following is a specification.
The main objects of this invention are to provide an improved form of truck bolster in which the connections between the tension and compression members are such as to secure great strength and simplicity of form; and to provide an improved construction for the joints between the ends of tension and compression members in which creeping of the tension member with respect to the compression member is impossible.
An illustrative embodiment of this inven-' tion is shown in the accompanying drawings in which- Figure 1 is a side elevation of the improved truck bolster, one-half of such bolster being shown in section. Fig. 2 is an enlarged detail of one of the extreme ends of the bolster. Fig. 8 is an enlarged detail showing a modified form of means for strengthening and reinforcing the shoulder on the end of the tension member.
In the construction shown in the drawings, a compression member 1, in the form of channel bar having a horizontally disposed web 2 and depending'marginalflanges 3, is provided at its medial part with a center bearing 4: and near each end thereof with side bearings 5..
A flat-strap-like tension member 6, having its medial portion held in spaced relation to the compression member 1 by a strut 7, is bent at such medial part so that its end portions meet the respective end portions of the web 2 of the compression member 1. The members have their ends secured together by suitable means such as rivets 8, and the end portions of the compression member 1 are bent upward in the general direction of the end portions of the tension member 6 which are in alinement with their adjacent body portions.
The end portions of the tension member are upset or otherwise thickened so that there is no reduction of area on account of the rivet holes, and the extreme ends of the tension member 6 are provided with upstanding and laterally extending shoulders 9 adapted to overlap and abut against the ends of the web and flanges 0f the compression member 1.
Means are provided for strengthening and reinforcing the shoulders 9 and comprise ribs 10 disposed longitudinally of and on the upper surface of the tension member 6,
the web of the compression member being recessed to receive these ribs.
In the modification shown in Fig. 3 the means for reinforcing and strengthening the shoulders 9 are ribs 11 formed on the under compression member renders it unnecessary to bend the end portions of the tension member; these being in alinement with their adjacent body portions, are much stronger than they would be if bent; and the rivets are subjected to shearing strain only. The end portions of the tension member are also thickened so that there is no reduction of area on account of the rivet holes. The shoulders on the ends of the tension member overlap and abut against the end surfaces of the compression member and these shoulders are strengthened and reinforced by 'ribs in such manner as to prevent the tension member from bending or breaking i the vicinity of said shoulders when subject (1 to great pressure. These ribs also prevent any .possibility of the shoulders yielding and allowing the compression member to creep so as to shear the rivets.
Although but one specific embodiment of this invention has been herein shown and described, it is to be understood that the construction may be altered or details omitted without departing from the spirit of the invention as defined by the following claims.
I claim 1. In a trussed truck bolster, the combination of a channel shaped compression member, a strut, a tension member bent over said strut and having its end portions bro ight alongside the web portion and betweenthe flanges of the compression member, said end portions being shouldered to overlap and engage the end surfaces of said Web portion and flanges, means for securing said members together at their ends, and longitudinal ribs on the ends of said tension member for strengthening and reinforcing said shoulders.
2. In a trussed truck bolster, the combination of a flanged compression member, a tension member having its end portions brought alongside the end portions of the compression member, upstanding shoulders on the end portions of said tension member adapted to overlap and engage the end surfaces of said compression member, means for securing said members together at their ends, and
ribs disposed longitudinally of said tension member and on the upper surface thereof, for strengthening and reinforcing said shoulders.
3. In a trussed truck bolster, the combination of a compression member having a horizontally disposed Web and depending marginal flanges, a tension member having its end portions brought alongside the web and between the flanges of the-compression member, a strut for holding the medial parts of said members spaced apart, the end portions of said compression member being bent upwardly, transversely disposed upstanding ,shoulders on the ends of said tension member adapted to overlap and engage the end surfaces of said compression member, ribs disposed longitudinally of and on the upper surface of said tension member for strengthening and reinforcing said shoulders, and means for securing said members together at their ends, the end portions of said tension member being in alinement with the adjacent body part of the tension member.
4. In a trussed truck bolster, the combina tion of a channel-shaped compression member having its end portions bent upward, a strut, a tension member bent over said strut and having its end portions thickened and brought alongside the web portion and between the flanges of the bent-up end portions of the compression member, means extending through said thickened end portions of said tension member for securing said members together at their ends, and shoulders extending upward and sidewise from the outer ends of the thickened end portions of said tension member and adapted to overlap and abut against the end surfaces of said web portion and flanges.
5. In a trussed truck bolster, the combination of a channel shaped compression member having its end portions bent upward, a strut, a tension member bent over said strut and having its end portions thickened and brought alongside the web portion and between the flanges of the bent up end portions of the compression member, at the outer ends of the thickened end portions of said tension member adapted to overlap and engage the end surfaces of said Web portion and flanges, and means for securing said members together at their ends.
