To all whom 4'it may concern:

Be it known that I, EDWIN H. BENNERS, a' citizen of the United States, residing in Elizabeth, county of Union Aand State ofl New Jerse have invented certain new and useful Si e Frames for Car- Trucks, of which the following is a s eciiication.

rl`his invention is a si e frame for car trucks, the 'same appertaining more especially to frames of that class which, in the main, are cast in one piece.

An object of the invention. is to facilitate the operation of assembling the bolster relative to the side frames, and to retain the bolster in position after it shall have been inserted `in said frames'.v

Am important advantage secured by my invention is that bolsters ofdifferent weights and sizes may be readily placed in position and retained within truck side frames of a standard size.

The side'frame of this'invention is designed and proportioned throughout its several elements with a view to reducing the weight to a minimum, While securin the strength required to withstand the loa and Ithe side or end thrusts, an especially irnportant feature being the ability of the side frame to-resist distortion which would result in disalinement of the axle boxes.

Each* side lframe is, preferably, 'of that.

class wherein the frame is cast in one piece. As will presently appear, said frame comprises an. arched top memb r, a bottom member, columns connecting t e top and bottom members, and stay members inclined with respect to the top and bottom'members, each of said members being of channeled form in cross section.

According to one embodiment of the invention, the columns are parallel to each other,r the space between said columns exceeding the width of the bolster which is to be used in connection "with the truck by in, sorting its end portions into the vertical openin which are formed between the. aforesaid columns. For retaining the bolster in position, itis provided on,its res sides with grooves, each roovel being orined by parallel flanges or r1 s, the latter being, preferably, inte ral with the bolster. Cooperating with t e grooved .bolster-are guide `.from the frame and are attached to the'columns therei of, said members protruding from the opl' ectiveV posing faces of said columns, and fitting inA the grooves ofthe bolster. is preferred to insert the guide members in the columns, provided with a recess bounded on all of its sides by walls, the latter being engaged by the-edges ofone gui'demember in such manner as to effectively retain the guide member in position, although it is preferred to fasten each guide member to a column by one or more bolts.V

From the foregoing it should be noted that a grooved bolster may have its end portion inserted into the opening of the side frame below the guide members, thus easily introducing said bolster, after which the bolster`is raised into the required position. At this time, the guide members enter the grooves in the bolster, and they operate thereafter to retain the bolster against sidewise or endwise motion relative to the side frame, saidv bolster being free, however, t0 move yorlay vertically within said truck and within the limits determined by the usual s rings. la t e 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.

and to this end, each column is.

so' A re 1 is a side elevation, partly in section, of a side frame embodying the present invention Fig, 2 is a plan view with parts broken away to show other parts in horiaontal section. Fig. 3 is a vertical cross section on the line 3,--3 of Fig. 1. Fig. 4 is a detail View of a part associated with abrakeibeam. Fi 5 is a horizontal section on the line 5-5 o Fig. 1. Fig. 6 is an inverted or bottom plan View of a part of the right hand to confine the present invention to a one piece frame, for the reason that certain features of said invention may be used in connrection with built-up frames. As shown,

'said frame consists of` a top member, a, a bottom member, the columns, c, c', and the L inclined struts or brace members, al,

i fr The top member, a, is arched from end to end thereof, although the end portions of said top member are flattened .on their lower sides, as at a', for the reception of the ped-` estals or aXle boxes, one of which is indicated lin part by the reference character B at the left hand portion of Fig. 1. As is usual in section, see -Fi s. 2 and 3, and it is preferred to provide sai top member, a, withdepending flanges, a3, from which extend rentrant flan es, a.

T e bottom member, b, is of channeled and skeletonized cross `seet1on, as shown 1n Figs. 1l and 3. The member, b, is provided structure possessin y, in the lower with upstanding side flanges, b', and'with intermediatel webs, b2, thus producing a the requisite strength with a vdecrease in t e Weight of metal.

The columns, c, c', join the top member, a,

With the bottom member, b, and as shown, these columns are equidistant from the middle portion of the frame. Said columns are parallel to each other, and they are of channeled form in cross section, see Fig. 5. Each colunm is shown as provided with side flanges, c2, and the middle portion of the column is provided with slots or openings, c3, which .tend to decrease the weightjof the metal.` The columns 0,-are joined at their lower portions with the 'bottom member, b,

and the inclinedstruts, d, d', .whereas the upper portions of the columns are joined with they channeled top member, a. The struts d, d, extend from the end portions of the b Ottom member, b, to the end portions of .the arched top member, a, so as to join with or merge into said members, a, b. Each inclined member is provided with side ribs, d2, thus producingl a strut of channeled cross section, see Fig. .7 i l C designates a spring plank which is'fitted part of the opening which is formed. in the side frame by and `between the columns, c, c', the top member, a, and the bottom member, b. .This spring plank may be of anyvusual or preferred construction, and it rests upon the flanges and webs, b', b2, of the'bottom member.

At the end portions of the spring plank are the angle reinforcing plates, D, one of which is shown in section in Fig. 1. The vertical member of this angle plate engages with the inner face of one of the columns, whereas the horizontal member of said angle plate rests upon the bottom member, b. The

,angle plate isfastened in position by bolts, e,

4which are shown in dotted lines in Fig. 3, and in full lines in Fig. 5, said bolts passing through the vertical member ofthev angle plate and also through suitable lugs, e',

which are provided on the column. Through the horizontal member of the angle plate,

passes a vertical bolt, f, the latter extending throu h a web of the bottom member, b, where y each angle plate, D, is held securely in position..

.Y As is usual in the art, the set of springs, shown partly in Fig. 1 and indicated by the reference character, E, 'is seated upon the spring plank, C, and these springs coperate with a bolster, F, for the purpose of holding the latter normally 'in a. working position within the side frame. Said bolster,`F,

tween the flanges, f2, on one side of the bolster and the corresponding flanges, f2, on the opposite sidel thereof. This proportion of the vertical opening in the frame, A., 'to the width of the bolster, F,fen ables an-end portion of said bolster to be thrust into or through the lower part of the aforesaid vertical opening in the side frame, the springs,

E, bemg temporarily out of place.

For the purpose of retaining the bolster against endwise displacement, and to guide said bolster in its vertical travel or play within the upper part of the aforesaid vertical opening, I employ4 thev G, one of which is provide face of each vertical column, c, c', whereby said juide ,member is ada ted to occupy one of the vertical grooves, f?, of the bolster.

The members, G, are arranged in corresponding positions at the upper portions of guide members, on the mner the columns, 0,0', and on the opposing faces thereof, said members being a short distance below the top member, a. VThe guidemembers, G, are parallel to each other, and they protrude from the opposing faces of the columns, whereby said guide members are fitted 'snu 1y in the grooves which are provided in t e sides of the bolster, F.

Each'guide member, Gr, is preferably cast vin a single piece of metal, and it is furthermore preferred to inset each guide member in one of said columns for the purpose of rigidly fastening the guide `member to the column in a way to reclude displacement of said guide member fiom said column. As shown 1n Figs. 1 and 2, each column is provided with a vertical recess,y h, which. is bound on four sides by the marginal walls or shoulders, lb', the recess being closed in l all its portions, 'except on 'the inner face ofl ons,

the column. rThe guide member, G, is re-` duced on one side so as to form the seat portion, g, which is bound by the shoulders, g, and this seat portion is fitted snugly 1n the recess, L, of the column, whereby the shoulders of the guide member engagey with the shoulders, it', -of the recess. The seat portion, g, of said guide member fits snugly in the recess, h, so that it cannot move in any direction therein, and when the bolster is in position so that the guide-member will en-4 gage with the groove side of the bolster, said guide member is retained in position within the recessed column. It is preferred, however, to fasten the guide member in position in the recessed part of the column, and for this purpose l have shown each guide member as beingheld in position by a transverse bolt, I, which passes through appropriate openings, z', which are provided in the channeled column so as to open into the recess, it.,

From the preceding description, it will be understood that the guide members, Gr, are fastened in positions on the columns, c, c', prior to introducing the bolster, F, into the vertical opening of the side frame. When suclrbolstcr is introduced, its grooved end portion passes int-o the aforesaid vertical opening below the guidemembers, Gr', after which the bolster, F, is raised, Duringthe elevation of the bolster the guide members, G, enter the grooves, f, thus bringing the guide members into cooperative relation to said bolster. The springs are novi7 inserted in position between the ,spring plank and the underside of the bolster, and, if desired, proper spring seats are employed for engagement with said springs.

As shown in Figs. 2 and 3, the side frame is provided lwith brake-beam hangers, J, which are preferably cast integralY with the top member, a, and the vertical columns, rf, c. These hangers extend from one side of the frame, and to the lower portion of cach hanger is connected a stirrup, y', by means of a bolt, j.
