SPECIFICATION forming part of Letters Patent No. 583,611, dated June 1, 1897.

Application filed February 27, 1897. Serial No. 625,826. (No model.)

T0 all 1.071.071? t 717/017/ concern:

Be it known that I, BENJAMIN W. TUCKER, acitizen of the United States, residing at Newark, in the county of Essex and State of N ew Jersey, have invented certain new and useful Improvements in Car-Trucks; and I do declare the following to be a full, clear, and exact description of the invention, suchas will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

The invention relates to car-truck frames, and pertains particularly to the side frames or beams, the transom connecting said side frames or beams, the pedestal-frames at the ends of the side frames or beams, and other features, as hereinafter described and claimed.

In accordance with this invention the side frames or bealns are duplicates of one another, and each is formed from a rolled beam or plate having, preferably, an inturned flange along its upper and lower edges, the ends of said side beams or frames having a short section of flanged beam applied thereto and preferably at the inner side thereof` to form a boxlike end at the ends of the side beams or frames. The pedestal-frames are of Wrought met-al and are vsecured upon the upper and lower portions of the side frames or beams by rivets or bolts which pass through the pedestal-frame and also through both the upper and the lower iianges of the side beams and the short sections of flanged beams which are applied, preferably, to the inner side of the side beams, adjacent to the ends of the latter, and the said pedestal-frames will either be removable from said frames as a whole or will have one section thereof removable to receive and permit the escape of the usual axle-boxes. The transom connecting` the side frames or beams preferably consists of-two parallel channel-beams having their flanges turned outward from one another and a channel-beam intermediate the vertical channelbeams and secured to the webv thereof, and also to the web of the side frames or beams, and the top plate will connect the vertical channel-beams of the transom and be riveted at its outer edge to the upper flange of the side beams.

The object of my invention is to produce a car-truck frame' of great efficiency and durability and capable of withstanding all of the severe usage and resisting the various strains to which car-truck frames are subjected.

The invention will be fully understood from the detailed description hereinafter presented, reference being had to the accom panying drawings, in Which Figure l is a top view of one side and a portion of the transom of a car-truck frame constructed in accordance with and embodying the invention. Fig. 2 is a side elevation, partly broken away, of same. Fig. 3 is an enlarged detached sectional View through a portion of the pedestal-frame on the dotted line 3 3 of Fig. l. Fig. 4 is an enlarged vertical transverse section through a portion of the side frame, on the dotted line 4 4f of Fig. 2, looking in the direction of the arrow. Fig. 5 is an enlarged transverse section through the truck-frame on the dotted line 5 5 of Fig. 2. Figs. 6, 7, and 8 are detached side elevations showing several modified forms of pedestal-frames which I desire to include within the scope of this application.

In the drawings, A designates the side frame or beam, which, as illustrated, is a plain beam cut off square at its ends and having the inwardly-turned upper andlower flanges, (lettered, respectively, B C.) At the ends of the side frame or beam A are provided the short beam-sections D, extending inward from the outer edge of the beam A to about the point indicated by the dotted lines in Fig. 2, denoting the inner vertical edge of said short beam-sections D. The beam-sections D are provided with upper and lower flanges, (lettered E F, respectively,) which flanges extend inward along the flanges B C of the beam A,

while the web of said beam-section D is flush with the outer vertical plane of the anges B C on the beam A, as shown in Fig. 4, whereby at each end of the side frame A a box-like section is formed, and two thicknesses of flanges are provided at both the upper and the lower edges of the side frame or beam A, adjacent to the ends of the latter.

The pedestal-frames are lettered G, and, as shown, are secured to the ends of the side frames or beams A and extend outward and downward therefrom. Referring to Fig. 2, the pedestal-frames G are each composed of the upper horizontal strap II, the outer vertical strap I, and the lower angular strap J, the latter extending along the lower edge of the side frame A to the end of said side frame, then turning downward in line with said end of the side frame A, and then turn ing a right angle and extending horizontally to meet the vertical end strap I. The end strap I is removably secured to the straps II J, the ends a of the strap I being turned outward at an angle from the main body thereof, and the ends l) c, respectively, of the straps II J, adjoining the strap I, being turned outward at a corresponding angle and contacting with the face of the bent ends c of the strap I, in order that the said ends a h and a c may be secured together b y means of the bolts d. rlhe extremities of the ends a a of the strap I turn over against the ends Z) c of the straps I-I J and form strengthening and supporting gibs, (lettered e.) The bolts d are more clearly illustrated as to their construction and arrangement in Fig. 3, in which it will be seen that the shank end of the bolt passes through a free aperture in the end c of the lower strap J and through a threaded aperture in the end a of the strap I, and is provided upon its end with a nut f, which, in view of the threading of the aperture in the end a of the strap I, serves to lock the bolt in position without the use of a jam-nut. By means of the bolts d the end strap I may be readily removed and restored to place, and hence for the insertion or removal of the axle-boxes the strap I is rendered convenient of removal, and when in place the said strap I will be found entirely durable and efficient for the purpose of guiding the aXleboXes and of withstanding the end thrusts to which it may be subjected when the car is in use.

I do not limit the invention to the employment of the gibs e in every intance, but said gibs will be found to be desirable and I recommend their use. The straps II J of the pedestal-frames are secured at their inner ends by the upper and lower rivets g g, which pass through said straps and through the upper and lower fianges of the side beam A and also through the upper and lower flanges of the short beam-section D, as clearly illustrated in Figs. 2 and 4. The vertical portion of the lower strap J and the vertical portion of the strap I are in line with one another and form guiding and rubbing surfaces for the usual axle-boxes, and the width transversely of the straps I J corresponds with the width of the boxlike end of the side frame A, and hence said end at the inner side of the pedestal-frarne G forms a cont-iu nation of the vertical portion of the strap J and serves to receive and guide the usual axle-boxes. The straps I-I I J are of wrought metal of substancured to the side frame in the manner shown and above described, it will be found to be entirely effectual and durable, and its attachment to the side frame is such as to insure its being firmly held and entirely capable of resisting the strains which in use are directed against it.

In Figs. 6, 7, and 8 I show several modified forms of pedestal-frames capable of attachment to side beams A in the manner presented in Fig. 2, and these will be referred to herein-- after.

The transom (lettered K) is composed ofthe vertical parallel channel-beams L L, whose flanges turn outward from one another, and the horizont-ally-disposed channel-beam M, which is intermediate the beams L L and has its edge fianges secured to the web portion of said beams L by means of the rivets 7L, as clearly indicated in Fig. 5. The ends of the channel-beams L L are secured to the upper and lower flanges of the side beams A by means of the rivets z'j, respectively, as clearly shown in Figs. l, 2, and 5. The ends of the intermediate channel-beam M approach the side beams A and then turn downward to rest upon the lower flange C of the side beam A and to permitof the web portion of the said beam M to be directly secured to the web lportion of the side beam A by means of the rivets or bolts m. The transom constructed and arranged and secured as described is of great efficiency and durability and effectuall y connects the two side frames of the truck.

The top plate N of the truck is riveted to the upper flanges of the beams L L and also to the upper flange B of the side frame A. The outer edges of the top plate N pass along the top flange B of the side frame A, as more clearly shown in Fig. 5, and is secured to said top flange B by means of the rivets n. rlhe ends of the top plate N extend outward to about the inner vertical edges of the short beam-sections D, as indicated by the dot-ted lines in Figs. l and 2. Thus the thicknes of the outer portions of the top plate N substantiall y continues the upper flange E of the short beam-sections D throughout the length of the upper edge of the side frame or beam A.

In Figs. G, 7, and 8 are shown modified forms of the pedestal G illustrated in Fig. 2, the construction of these modified forms of pedestal-frames being apparent from the foregoing description and an inspection of said figures. In Fig. G the outer vertical member IOO IIO

IIS

Fig. 7 the upper member H and the outer vertical member I of the pedestal-frame are integral, and the lower member J has its horizontal portion removable from said member I, as in Fig. 2, and also from its remaining parts. In Figs. 2, (j, and 7 the pedestal-frame is shown in each instance as being in part rei side A and the upper and lower flanges of the short beam-sections D. Unless some particular member or members of the pedestal-frame is removable, it will'beA necessary to removably secure the said frame as a whole to said side A. In all of the forms of pedestal-frames shown the box-like end formed at the end of the side frames is in line with the inner vertical portion of the pedestal-frame proper and forms a continuation thereof. The web of the side A and the web of the beam-section D at their ends form an open box whose outer edges will be adapted to receive and guide the usual axle-boxes. The open box-like ends at the ends of the side frames A permit the convenient application of the rivets g, by which the pedestal-frames aresecured to the sides A. At the upper ends of the pedestalframes will be provided the integral inverted sockets or receptacles t, which will preferably be provided with the vertical end gibs w and top horizontal gibs x, thegibs w being adapted to engage the vertical memberof the pedestalframes and the opposite edges of the box-like frame at the ends of the side frames, while the top gibs x will engage the opposite edges of the horizontal member H of the pedestalframes, as clearly indicated in Figs. l and 2. The gibs w x will serve to center and guide the sockets t and prevent the latter from having any twisting movement.

The beam-sections D have been referred to above as short beam-sections, but it is not intended thereby to limit the said sections D to the length illustrated in the drawings. The said sections D will be found to be entirely efiicient if given the length indicatedin Fig. 2, but they may be longer, if desired. The said sections D, when applied to the ends of the side frames A, afford proper strength for said sides and render the attachment of the pedestal-frames secure and combine with said sides to form an open box -like outline which is adapted to form a part of the pedestal and to receive and guide the usual axle-boxes. The

pedestals will, as usual, be provided with the customary axle-boxes and springs.
