BOLSTER.

SPECIFICATION forming part Of Letters Patent No. 721,131, dated February 17, 1903. Application filed December 18, 1902. Serial No. 135,802. (No model.)

To a/ZZ whom it may concern:

Be it known that I,JOHN C. WANDS, a citizen of the United States, residing at St. Louis, Missouri, have invented aV certain new and useful Improvement in Bolsters, of which the.

following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, inv which- Figure l is a side elevational view, partly broken away at one end. Fig. 2 is a top plan View of one end of my improved bolster. Fig. 3 is a Vertical sectional view ofl the several parts comprising one end of my improved bolster separated for the purpose of better showing the details of construction thereof. Fig. 4 is an isometric view of the upper section of the head-block.v Fig. 5 is an inverted plan view of the same. Fig. 6 is a plan view of the lower section of the head-block. Fig. 7 is an end View of the same, and Fig. 8 is a plan view of one end of the tension member of my improved bolster.

This invention relates to anew and useful improvement in bolsters designed for use either as truck-holsters or body-holsters.

The object of the invention is to construct a bolster with commercially-rolled compression and tension members united at their ends by means of head-blocks composed of a plurality of sections adapted to interlock with each other and with the tension member of said bolster; and the invention consists in certain features of noveltyin the construction of the same, all as will be hereinafter more fully described, and specifically pointed out in the claims.

Referring to the drawings, l is the compression member of my improved bolster, consisting of a com mercially-rolled channel cambered at its central portion.

2 is the tension member of my bolster, comprising a flat plate of commercially-rolledV metal which has at its end portions a series of openings 3, preferably angular in shape.

A is the upper section of the head-block, which section is provided on its upper side with the recess 4, having the downwardlyprojecting recesses 4.,'the recess t being adapted to receive therein the web of the compression member, while the recesses 4a are adapted to receive the flanges of said compression member. The memberA is provided with a shoulder 4b for the end of the compression member, which shoulder serves as a stop therefor. The under side of the section A is recessed, as at 5, whereby there is formed a seat for the end of the tension member 2, the lugs or projections 6 extending downwardly from the section A and passing through said angular openings 3 of the tension member and into and through the openings 7, formed in the upper face of the lower head-block section B, while dowels 8 project upwardly from said section B and interlock with recesses 9 in the lower face of the section A, thereby uniting the said sections A and B and, by means of the said lugs 6, securing the tension member of the bolster lirmly in position within the head-block, the end ofv said compression member abutting against the shoulder 4b of thesection A.

E indicates the king-post or strut, which is preferably formed hollow for the passage of the king-bolt, said strut being provided with lateral flanges adapted to afford an extended bearing for the compression member and also provided with webs ll between said flanges and the vertical portion of said king-post, which webs serve to strengthen the same.

The lower section B of the head-block is preferably cast hollow, as best shown at Figs. 3 and 7, and between the horizontal walls thereof are provided vertical partitions 12, which serve to strengthen said section B, said walls extending from the outer ends thereof to the opposite end of saidsection B.

The sections A and B of thehead-block are both provided with sho'uldersor vertical ribs 13, which serve as column-guides.

In assembling the dierent parts of my improved bolster the tension member'is placed in position upon the lower section B, with the openings 3 regist'eringwith the openings 7 of said section, whereupon theupper-section A is placed in position with the lugs 6 projecting through both series of openings 3- and 7 and passing into the hollow portionrof said section B, after which the strut is placed -in position on said tension member and the com- IOO pression member is placed upon the strut. The compression member is not secured permanently to the head-block nor are the several parts of the head-block permanently connected together, as it will be found that the weight of the car upon the compression member will be suicient in practice to hold the several parts in their proper cooperative positions; but, if desirable, a temporary securing means may be used to hold the compression member in place upon said head-block, which securing means may be any convenient means which will accomplish the result, such as a pin passing through the ianges of said compression member into the section A of said head-block, or any other convenient means may be used, such as the upset lug 15, integral with the head-block A.

It will be observed that when the parts are assembled for use the sections of the headblock are united by the same means which hold the tension member in position, and it is immaterial whether the lugs 6 be cast integral with the upper section A and the openings 7 be formed in the upper face of the section B or whether said lugs shall project upwardly from the section B and register with` corresponding recesses in the section A, as either construction will be Within the spirit of my invention.

For the purpose of securing the requisite strength the tension member is made relatively longer than the compression member and, as seen in the drawings, projects therebeyond for ashort distance at each end Within the head-blocks.

The head-block sections and lugs 5 are preferably made of malleable castings, and to permit the same to be properly annealed are preferably formed three-eighths of an inch in thickness at all points where annealing is desirable.

I am aware that minor changes in the construction, arrangement, and combination of the several parts of my device can be made and substituted for those herein shown and described without in the least departing from the nature and principle of my invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
