CAST-STEEL SIDE FRAME FOR Specificaiiion of Letters Patent. Application filed October 22, 1906. serial N0. 840,018-

CAR-TRUCKS.

I, Y I Patented .n'u as) leo'z.

class wherein the journal boxes are rigidly secured in the truck side-frames, and wherein the truck bolster is supported by springs in or upon said side-frames. In a truck of this class the truck-bolster is usually of about the same length as the car axles, and its ends extend through or beyond the side frames, the bolster springs being arranged in the vertical 'planes of the sideframes. 7 7 1 I The object ofmy invention is to improve the con struction of the side-frames of car trucks of the class mentioned, and the particular object of the invention is to providean improued cast-steelside-framefor cartrucks. I

Further and particular objects of the invention are to provide single-member cast-steel side-frames of such character that'the bolster may be inserted into the openings .of said frames after the frames and. journal boxes have been placed upon the truck wheels; further, to provide an improved single-member side-frame which shall be characterized asabove and which nevertheless, shall have continuous or uninterrupted top and-bottom chordal portions or flanges. Other objects-of my invention will appear hereinafter.

My invention consists generally in a railway car tiuck and particularlyin the improved side-frame for such truck, all as! hereinafter described, and particua larly pointed out-in the claims.

The invention will be more readilyunderstood by reference to the accompanying drawings, forming a part of this specification, in which Figure lis a sideelevation or" a railway car truck embo'dying my invention; Fig. '2 is'a; partial plan view thereof; Fig. 3 is an? enlarged side view of the-middle portion of my nov'eli'gg'g frame; Fig. 4 is a vertical sectionthereoi, on theiiflfiDLJV oi Fig.3; Fig. 5 is a horizontal'section onlin V QV: of Fig. 3; Fig,' 6 is a view like unto Fig,, 5, illustrating a bolster guide or v column block of modified form; and Figs. 7, 8 and 9 are like views, disclosing guidebloclis of still other form;

As shown in the drawings, 2"2 represent the wheels oi a car truck; 33,-, the axles, and 44 the journal boxes. 5 represents the truck bol'ster,-and 55' the? bolster gtudea forming a part of the bolster. The parts of the trick here naehtio ied may be of.an-y suitable dle of the beam; is of greater 'width than the bolster form and construction adapted for employment with rigid side-frames, My novel side frame comprises a single steel casting, A, having ends, B, that are adapted to rest upon the,

tops of the journal boxes, and at the middle provided ,with an openiug, C, which latter is at all points or heights of greater width than the bolster, 5, including its guides, 5. I,prefer that the side-frame shall partake of the form of an irregular but symmetrical flanged beam, and as here shown it comprises a web portipn, D, and top and bottom flanges or chordal portions, E and F; the middle of the beam is of considerabledepth, as required to accommodate the bolster and the bolster springs, while theends are of much reduced height. The ends of the beans are secured upon the journal boxes by the usual box or pedestal bolts. It willbe understood that the dip or drop of the middle portionof the beam maybe as little oras great as-requ'ired, to

adapt the trucks to cars of various heights. A tie bar or bars, 6, of suitable form, may be employed to tie or brace the journal boxes at the bottom, or the beam, A, may itself be formed'to brace said boxes.

As stated, the rectangular opening/O, in the midand its guides. My purpose inthus constructing the side frame is to facilitate the assembling and the disas thebolster may be inserted or threaded endwise through the side-frame, it is unnecessary. to delay the assembling of the truck until the bolster has been -Ineniberment 0f the truck, and it will be obvious that placed, or to first remove the, side frames from the journal boxes, preparatory to the removal of the bolster. It is not-even necessary to remove the bolster springs, v7, from the side-frames. In other words, certain means which I employ for guiding thev bolster in the side-frames are of such character that the full opening of the side-frame above the springs is at all times available for the insertion or removal- 0f the bO l': ster; hence, the bolster may be readily placed in or removed from the truck after or while the side frames are rigidly secured together and-.iupon the journal boxesythe bolster guiding means rejferred tol'comp'rise short blocks,'GG' which al 'removably secured in 'theupper part of the side-frame opening. These fit the bolster guides and constitute jtheiac tual""'guidei" columns of tlie sideframes although as hereinafter de scribed the side frame has its own integral column-r portions. As shown in Figs. 3, 4 and 5, I prefer to provide the frame or. beam, A, with side flanges or projecting-ribs or columnportions, H-H framing the upper part of the opening, 0. These flangesor coh vumn portions do not extend-to the bottoni of the beam; instead, notches or recesses, Hfl are provided therein at the lower part of the opening to adinit the guide blocks, G. E:a;clrguide-lolock comprises 'a's mall,

angular casting, shaped to fit the cross-sectionaliorm of the column portions, H, of the side-frame. (See Figs. 4 and 5.) When the bolster and the springs have been placed in' approximate position within the sideframe, the blocks G, are inserted at the lower part of I the opening and are then raised or slid upwardly into interlocked position with the flanges or column portions, H,'in which position they enter .the guides, 5, of the bolster. 1 Little labor is involved in thus securing the bolster by means of the guide blocks or separablecolumns. Each guide-block, G, is secured to the web onthe sidefranie Joy-two bolts, .G, and each block carries a brake-hangerbracket, G formed'integrally therewith. Thus in one operation the bolster is secured .inplaceand the. side-frame is prepared toreceive the brake-beam hangers. p I

A non-essential and yet desirable feature of my sideframe resides in the .widenedlower flange, F, of the beam which adds to the strength of the beam andprovidesa perfect spring-seat.

A substantial equivalent of the column block, G, above described, may be had, and the employment ofthe flanges, H,'may be avoided by forming the guide or column block in the manner shown in Fig. (SJ This block,l, has an inner portion, 1, of sufficient width. to fit the bolster-guide 5 and its outer portion is bifurcated to fit the web portion D of the side-frame to,

, which it is secured by a bolt, 1 Here, .as before, the;

brake hanger bracket is an integral part'of the guideblock. 8 illustrates a form of my side-frame in which the guide-block J and the hanger, bracket J are separate parts, the latter, J, being integral withthe side-frame. In 7 I have shown my invention ina form adapted for employment with bolsters having guides 5 which are not in alinement with th side-frame. In this case the guide-block, K, and the hanger-bracket, K, are applied: to one side only of the side-frame, being secured by suitable bolts, K

Fig.7 illustrates another form of the guide-block applied to the inner side of the beam or side-frame, but occupying a central position. In this case the web portion D of the frame is provided with a guide-block pocket or recess, L in its inner side adjacent to the large bolster opening. The block, M, fits the pocket and is secured'bya bolt, M. Here, as before, the l prising a sideframe made of a singlepicce of metal, provided with a bolster andspring opening and'having short device lends itself'to ready combination with the brake-hanger bracket, M

Asvarious modifications of my invention will read ily suggest themselves to one skilled in the art, I do not limit the invention to the specific constructions herein shown and described. I

Having thus described my invention I claim as new and desir'eto secure by Letters Patent:
