SPECIFICATION forming part of Letters Patent No. 728,479, dated May 19, 1903.

l Application filed August 27, 1902. Serial No. 121,155. (No model.)

To all whom it may concern.'

Beit known that we, JOHN E. LOMBARD and JOSEPH R. BOWLING, citizens of the United States, residing at St. Louis, inthe State of Missouri, have invented a certain new and vuseful Improvementin Bolsters for Railway- Oars, of which the following is a full, clear,

` and exact description, reference vbeing had to the accompanying drawings.

This invention relates to steel bolsters of the general type shown in Patent No. 694,385, granted March 4:, 1902, to the Ingoldsby Auf tomatic Oar C0., as assignee of Fra-nk S. Ingoldsby and Joseph R. Bowling.

The object of the present invention is to strengthen and stien such a bolster and at the same time rendering its construction simpler and cheaper. n

The invention relates particularly tothe construction at the outer ends of the bolster, as hereinafter fully explained.

In the drawings, Figure 1 is a side elevation of something over one-half the bolster sectioned through the contiguous portions of the car. Fig. 2 is an enlarged side elevation, partly broken away, of a portion of the bolster at the end thereof. Fig. 3 is an elevation of the end of the bolster. Fig. 4. is a plan view of the bolster near its end, and Fig. 5 is a vertical section on the line 5 5 of Fig. 2.'

In its complete form the bolster shown comprises a central frame A, a channel-shaped compression member B, extending beneath the frame and diagonally upward therefrom, a tension-strap C, extending over the top of the frame and secured at its ends to the compression member, tension-braces D, leading from the compression member to the central frame, compression-braces E and F, connecting the tension -strap with the compression member, and a suitable center bearing G and side bearings H, carried on the under side of the compression member.

Whenv installed in the car, vertical draftplates J preferably engage the sides of the central frame of the bolster and are riveted to it, 'and a longitudinal sheet K of inverted- V form lies between the central frame and the tension-strap, being secured to each of them. Diagonal beams L from the end to the sides of the car'may extend through the compression-braces F. The side of the car which rests upon and is secured to the outer end of the bolster may have, as shown, a sheetmetal plate N, a channel-beam N', and an inclined Z-str-ut N2. l

The above-described construction is shown and claimed partly in the patent to Ingoldsby and Bowling referred to and partly in an application of Ingoldsby and Bowling led on the 25th day of August, 1902, and numbered serially 120,922, and no claims are made herein for any such features.. y

The particular purpose of the present invention is to strengthen and stiften the outer ends of the bolster. The means by which we accomplishthis willnow be described.

Secured to the under side of the channel member B, at its outer end, is the angle-clip P. The tension-strap O isV bent downward at its outer end, as at c, where it is riveted f to the angle-clip P by the rivets p. Between the tension-strap and the compression member is a filling-block Q. The tension-strap extends inward horizontally on top of the filling-block, beyond which it inclines upl ward.

Extending over the top of the tension-strap C is a peculiarly-shaped stirrup R, which is secured to the tension-strap and to the compressionmember. This stirrup is formed of a vsheet-metal plate, which is bifurcated on opposite sides by having pieces cut out of it at @after whichitis bent into the inverted-U shape or stirruplform, presenting a substantially horizontal top plate r' and an inclined top plate r2 and vertically-depending plates r3 andr4, whichv are riveted to the anges of the compression member at fr5 and rs, respectively. Rivets rl hold the inclined portion r2 vof the plate to the tension-strap. Rivets rg pass through the compression member, the filler-block, the tension-strap, the'stirrup, and the flange of the channel-beam N.

A rivet r9 passes through the compression member, the filler-block, the tension-strap, the stirrup, and an angleclip N3, which is secured tothe inclined Z-beam N2. Another rivet rr11 passes through all these parts and also through the angle-clip P. Other rivets '1112 pass through the compression member, the filler-block, the tension-strap, and the stirrup.

The above specic description of the rivets shows how simple it is to construct this portion of the bolster, While at the same time the parts are very securely held. There are no inaccessible places to rivet. The stirrup not only provides a reinforcing thickness for the tension-strap C, but a vertical depth for the whole end of the bolster, thereby greatly increasingitsstitinessand strength. Theopenings fr in the side plates of the stirrup allow the stirrup to be very easily formed from a fiat sheet-metal platte.

We claim- 1. In a bolster, the combination of a channel-shaped compression member, a tensionstrap secured tothe com pression member near its end, and a sheet-metal stirrup extending over the tension-strap and secured to it and riveted to the side anges of the com pression member.

2. In a bolster, the combination of :t channel-shaped compression member, a tension member secured thereto and extending inward horizontally from the end of the bolster and then inclining upward, and a stirrup composed of a sheet-metal plate bent into a vertical U form and bifurcated on opposite sides, the intermediate portion thereof being bent at an angle to itself corresponding to the bend in the tension-strap, said stirrup being secured both to the tension-strap and the compression member.

3. In a bolster, the combination of a channel-shaped compression member, a fiat tension-strap bent down at its end across the end ofthe compression member and there secured, a stirrup lying on the upper side of the tension-strap and extending downward along the sides of the compression member, rivets passing through the downward extensions of the stirrup andthe sides of the compression member, portions of the car side resting on the upper face of the stirrup, and rivets passing through such portions, through the stirrup,4

through the tension-strap, and through the compression member, and securing said parts together.

In testimony whereof we hereunto affix our signatures in the presence of two Witnesses.
