CAR-TRUCK SIDE FRAME;

Specification of Letters Patent.

Patented March 31, 1908.

Application filed Qctober 22, ms. Serial No. 840,019.

To all whom it may concern:

Be it known that I, ARTHURLIPSOHUTZ, a citizen of the United States, and a resident of Chicago, Cook county, Illinois, haveinvented a certainnew, useful, and Improved Car-Truck Side Frame, of which the following is a full, clear, and exact description, such as willenable others skilled in the art to which it appertains to make and use the same. b

M invention relates to railway car-trucks and has special reference to improvements in trucks of that class wherein the journal boxes are rigidly secured in the truck side-frames,

and wherein the truck bolster is supported bysprin s in or upon said side-frames. In a truck'o 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.

The'object of my invention is to improve the construction of the side-frames of carass mentioned, and the particular object of the invention is to rovide an improved cast-steel side-frame orcartrucks.

Further and vention are to provide single-member caststeel side-frames of such character that the bolster 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 as above and which nevertheless, shall have continuous or uninterrupted top and bottom chordal portions or flanges. Other objectsof my invention will appear hereinafter. My inventionwill be more readily under-- stood uponreference to the accompanying drawings, forming a part of this specification, and in which Figure l is a side elevation of a railway car-truck embodying "m invention; Fig. 2 isa partiahplan view t ereof;Fig.j 3 isan inner side new of my novel side-frame Fig.

418 an enlarged vertical section'on the line X Xof Fig. v1, the bolster and springs bein removed; Fig. 5 is'a similar cross-sectionsfi view, showing a modified form of the sideframe, :wherem the brake hanger brackets areintegral'withthe beam; and ,,Fig. 6 illusparticular objects of the 111-.

may be inserted into the openings of said frame." The ures disclose the vertical transverse thiiifitrates a modification of my invention in which the upper middle portion of the frame,

which is constructed to avoid the end of the bolster, is located at the point between the upper and lower flanges or portions of the ame.

As shown in the drawings, 2-2 represents the wheels of a car-truck,- 33 the axles; 4-4 the" journal boxes; 5 the bolster, 5 the bolster guides, secured upon the bolster; 6-6 the bolster s rings, and 7, a bottom tie-bar; The arts of the car truck .here mentioned may e of anysuitable form or construction adapted for employment with rigid side'- frames. My novel side -frame com rises a single steel casting,- A, having ends, that are secured upon the tops of the journal boxes by the usual bolts, which latter also secure the ends dle portion 'of the side-frame or beam is provided with a bolster and spring opening or gap, 0, which is open at the top to receive the bolster.

The bottom and the top flanges or chordal portions, D and E of the ame are continuous but said top portion is curved outwardl adjacentto the. opening, 0, thereby provid ing s ace for the admission of the bolster, .as is we 1. shown in Figs. 1,2 and 3. The out wardly curved port1on,-F, affords the re uisite strength inthe upper part ofthe side frame therefore without closin the top of a between t e main ortions of the top o? t e side frame is briei and closed by a light locking bar, F, belted upon the top flange. This barserves tohold the bolster in place after the springs and bolster are assembled in the frame.

of the tie bar, 7. The midged As shownin Figs}. 2, 3 and. 4, Iprefer to brackets may be made integral with the sideframe, as shown by F in Fig. 5. The dotted lines in Fig. 2 and full lines in the other ened portions or flanges, G, which constitute the bolster guides or columns. These are tegral with the remainder of the single- 'eoe beam or frame. I preferthat the owe'r flange, G, of the side frame shall be expanded or widened (see D) at the middle of *the beam, to form a spring-seat. The web portions of the side-frame are preferably thinner than the marginal portions or flanges :for

- sake of lightness, but for certain uses the middle portion of the side-frame may be of uniform thickness throughout.

It will be obvious thatthe necessary braceffect of the outwardly curved or bent beam may be obtained in the manner indicated in Fig. 6, wherein the portion, E occupies a lower position being intermediate the up er and lower en of the column portions. advantage oft 's construction resides in the freer access af forded to the ends of the bolster.

In assembling my novel railway car truck the journal boxes are rigidly secured to the side frames and are laced upon the axles; the side-frames are tien tied and braced by suitable members (not shown) of ordinary design, after which the truck is ready to re ceive the bolster, 5. The springs beingi placed in position, the bolster is next lowere into the spaces or openings in the side-frames and properly enga ed with the guides 'or columns thereof. he locking bars are then bolted upon the frames to secure the bolster therein and preparatory to the equipment of the truck with brakes.

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