Specification of Letters Patent.

Patented Nov. 24, 1905.

Application filed. April 23, 1908. Serial No. 428,788.

To all whom it may concern:

. sters for such trucks.

For a number of years pastmuch experiment has been resorted to b railway engineers with a view to per ecting railway trucks in so far as concerns their safety, du rability, and strength, accompanied by reduction in weight, simplicity in construction, economy in manufacture, etc.; and many improvements have been made in these directions.

My new car truck embodies many advantages along the lines mentioned, particu-- larly as regards its lightness, strength, sim plicity in construction, and the ease and expedition with which the parts thereof may be assembled. It is of the same general form and contour of those heretofore used, but possesses salient novel features of construction not heretofore embodied in structures of this character, which novel features of the use of standard bolsters without necessitatmg the use of openings in the side frame, between the column guides, which were narrower at their upper ends than their bottoms, or narrower at the lower ends than at their upper ends. In contradistinction to the foregoing constructions of side frames, the present construction embodies column guides of a particular type with bolster openings between them and which openings are of the same width at their tops as at their bottoms. .This construction permits the introduction of the bolster at any point within the opening in the side frame, after which the bolster is secured against-endwise and lateral movement, while permitting free vertical movement, by means of the hereinbefore mentioned guide blocks cooperating with the bolster and the column guides.

In the accompanying drawings, I have illustrated one practical embodiment of the invention, but the construction shown therein is to be understood as illustrative, only,

and not as defining the limits of the invention.

Figure 1 is a vertical section taken longitudinally through a side frame embodying the present invention, the bolster being shown in cross section, and the guide blocks in elevation. Fig. 2 is a vertical cross section through the side frame on the line 2-2 of Fig. 1 looking in the direction of the arrow, the bolster, the guide blocks and the bolster supporting springs being omitted. Fig. 3 is a horizontal section through the side frame on the line 3-3 of Fig. 2, showing the bolster and the guide blocks in plan. Fig. 4 is an elevation of one of the guide blocks disconnected from the side frame and the bolster. Figs. 5 a longitudinal section on the line 5-5, and a cross section on the line 6-6 through the guide block shown in Fig 4.

and 6 are, respectively,

V The side frame, A, is similar in many particulars to the structure disclosed in my prior Letters Patent, No. 872,790, dated De cember 3, 1907, said side frame being cast in single piece. The frame consists of a top member, a, a base, 1), column guides, 0 c, and the inclined members, d, d- Preferab I top member, a, is curved throughout. its

length, and said top member is provided with depending side fianges, a, and reentrant flanges, (L as shown in Fig. 2, the top member being channeled 1n cross section.

The base member, b, is preferably skeletonized, and said base member is connected with the top member by the column guides, c, 0', and the inclined members,- (Z, d. The end portions of said top member, a, are fashioned to provide seats, 0, adapted to accommodate .the journal boxes shown partly at f, f, in Fig. 1.

An important feature of my new side frame consists of .the column guides, c, a, each of which is, preferably, double-channeled, as shown in'Fig. 3. Each column guide consists of a web, g, flanges, h, h, extending in one direction from the web, and

ly,'the

other flanges, 2', i, extending'in an opposite direction-from the web, said flanges, @565, be-

the lower part of said web, is provided a transverse opening, is, shown more clearly in Figs. 1 and 2, the purpose of which will hereinafter appear.

The bolster, B, may be of the standard construction, although any appropriate form of bolster maybe used. The bolster shown in Figs. 1 and 2, is composed of a single casting which is provided with flanges or ribs, I), but the widest part of'the bolster, between the flanges, b, is less than the width of the space between the column guides, 0, 0, whereby the bolster may be introduced into the bolster opening of the side frame at any point in the height of said bolster opening. In connection with thebolster, B, and the I column guides of the side frame, I employ guide blocks, C, C, each block being constructed as shown in Figs. 4, 5, and 6 of the drawings. Each block consists of a single cast metal piece, which is preferably skeletonized, as at Z, for lightness and simplicity, and said block is provided with flanges, m, m, which project from the sides of the block, and extend lengthwise thereof. The

block is provided, also, with a transverse bolt opening, 0, one end of which is enlarged to produce a recess, 0, in that face of the block which is adapted to enter the guide channel, 0 of the column guide. blocks, C, C, are adapted to be fitted against the respective sides of the bolster, each block occupying a position between the flanges or ribs, Z), of said bolster,and each block is secured firmly in position on the bolster by a transverse bolt, D, said bolster being provided with a bolt opening, if, in each side thereof.

In assembling the parts composing the truck, the bolster is introduced into the space between the column guides at any suitable point, and, preferably, said bolster is lowered to a position opposite the opening, is, in the column guides. The guide blocks, C, C, are now placed in position against the respective sides of the bolster, between the flanges, 6, thereof, said blocks entering the channels, 0 of the column guides. The blocks and the bolster should occupy a position at the bottom of the column guides, and

The

eoaevo each block is adjusted so that its bolt opening, 0, will register with the bolt opening,,(Z

of the bolster, after which the bolt, D, is introduced through the opening, 11:, of the col umn guide, whereby the bolt is adapted to pass through the opening, 0, of the guide block and the hole, "(2 of the bolster. The nut, CF, and a suitable washer are applied to the 01lt8l 8ll(l of the bolt, the head of said bolt beingreceived in the recess, 0, of the guide block. The guide block is thus fastened securely to the bolster by a single bolt, the head of which is countersunk in the recess, 0, of said guide block, whereby the guide blocks are attached directly and fixedly to the bolster so as to move vertically therewith.

After the guide blocks shall have beenattached to the bolster, the springs, E, are inserted below the bolster, said springs resting on the spring plank, F, the latter being of usual construction and supported on the base member, 7).

The guide blocks, 0, G, travel easily and freely in the channels, 0 of the guide columns', whereas the flanges, m, m, of saidguide blocks engage with the edges of the flanges, h, 72/, of the columns, thereby securing a plurality of engaging faces between the guide blocks and the-column guides. 'The' guide blocks effectually preclude the bolster from endwise and sidewise movement between the guideeolumns, while permitting the bolster and the blocks totravel freely in a. vertical direction between said columns. The guide blocks move easily in the channels of the columns so as to reduce the friction and wear on the parts, but as said blocks are secured fixedly in position on the bolster, they overcome any lost motion or grinding action between the bolster and the guide columns. Said guide blocks are adapted to be easily and quickly secured to the bolster by simply thrusting the bolts through the open ing, 70, of the column guides, and placing the bolts in position in the openings, 0, (P, of the guide blocks and the bolster.

l t will be noted that the guide blocks are positioned between the flanges or ribs, 6, of the bolster, thus relieving the strain on the bolts, D, under the end thrust which is improper points between the ribs 5, whereby the guide blocks are adapted to be fastened to said bolster.

The double-channeled construction of the column guides, c, 0, adds materially to the umn guide is provided with two channels,

with a minimum amount of metal, said con one channel, 0 being on the inner face of i said bolster and cooperating with the chanthe column guide, and the other channel on the outer face thereof. The channel guides are substantially I-shapcd in cross section, and the maximum strength is thus secured struction providing a channel on the inner face of the column guide, which channel is adapted to cooperate with the bolster guiding means.

In Fig. 2, the side frame is shown as having a bracket, G, cast integral with the top member, or with the top member and one column guide. This bracket extends from the inner surface of the side frame, and it accommodates a link, g, from which is suspended the brake beam, as is usual in this art.

II designates a brace bar, consisting, preferably, of strap metal which is bolted to the bottom members, the end portions of said stra being extended for engagement with the ournal boxes, f.
