UNITED STATES PATENT OFFICE.
SAMUEL P. BUSH, OF COLUMBUS, OHIO.
BOLSTER FOR CARS.
SPECIFICATION forming part of Letters Patent No. 701,837, dated J' une 10, 1902.
VApplimation led August 19, 1901. Serial No. 72,531. (No model.)
To aZZ whom, vt wwf/y concern.: n
Be it known that I, SAMUEL PEESCOTT BUSH, a citizen of the United States, residing at Columbus, in the county of Franklin' and State of Ohio,-have invented a certain new and useful Improvement in Bolstcrs for Cars, of which the following, taken in connection with the accompanying drawings, is a specification.
The first of the objects of ymy present invention is the provision of a car-bolster having an integrally-formed compression member and strut lcombined with a separatelyformed tension member and means for securing the ends ofthe tension and compression members together.
Another objectofmy invention is the provision of a bolster` .having an integrallyformed compression member and strut combined with a separately-formed tension member, the compressionmember being formed with the side bearings also integral therewith.
Another object of my invention is the construction of a car-bolster having an integrallyformed compression member and strut, with which are also formed integrallyy the side bearings and center plate.
Another object of my invention is the combination,with the compression member, strut, and tension member of a bolster, of a. separately-formed tension-member seat for transmitting the strain between the strut and tension member.
The above, as well as suc-h other objects as may hereinafter appear, I attain by means of a construction which Ihave illustrated in preferred form' in the accompanying drawings, in which- Figure l isa plan view of a bolster embodying my invention. section thereof, taken on the line 2 of Fig. 1. Figi 3 is an inverted plan view of my improvement applied to a bolster. Fig. 4 isa section on the line -l of Figs. 1 and 2. Fig. 5 is a section on the line 'of Figs. 1 and 2.
In carrying out mypresent invention I provide rst an integrallyvformed preferably cast compression member and strut, which I have marked 6, of which the compressionmember portion 7 is preferably of channel shape and the strut portion 8 arranged to project downwardly from said channel and Fig. 2 is a longitudinal which, as shown, is braced by means of the fianges 7a of the compression member. The tension member 9 is preferably of a strap form and where it engages the strut is provided with a tension-member seat 10, as shown in Fig. 5, which can be made separate from the strut for convenience of the casting of the combined compression member and strut, but which by the use of a little coring could be cast integral with the compression member and strut, if desired, and would be thus formed also within the contemplation of my invention generally considered.
The compression-member part 7 is preferably made with a center plate 11 and also vside bearings 12 and brackets 13, all formed integral with the compression member, as shown in Fig. 2, and the ends of the bolster are provided with end castings 14, between which and the compression member the ends of the tension member 9 are secured by means of rivets'l, passing through both the com-l pression and tension members and the end casting.
Having thus described my invention, what I claim as new, and 'desire to secure by Letters Patent, is-
1. A car-bolster comprising an integrallyformed compression member and strut, in combination with a single plate tension member, and means for securing the ends of the tension and compression members together, substantially as described.
2. A car-bolster comprising an integrallycast compressionV member and strut, in combination with a separate single plate tension member, and means for securing the said tension member and compression member together at the ends of the same, comprising end castings secured upon one side of the tension member, and rivets passing through the end castings, the tension member, andthe compression member, substantially as described.
3.y A car-bolster having a channel-iron compression member, said compression member having a center plate and side bearings formed integrally therewith, a tension member, a strut, and means for securing the compression member and tension member together at the ends of the same, substantially as described.
4. A car-bolster comprising an integrally- IOC member, and means for securing the con1 pression member and tension member together at the ends,substantially as described.
In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
SAMUEL P. BUSH.
