BENJAMIN WV. TUCKER, OF NEIVARK, NEV JERSEY.

CAR-TRUCK.

SPECIFICATION forming part of Letters Patent No. 583,613, dated June 1, 1897.

Application filed February 27, 1897. Serial No. 625,328. (No model.)

To all whom, it may concern.'

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

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

In accordance with-the present invention the side frames or beams are formed with inwardly-turned upper and lower flanges, be- -tween which the ends of the transom are securely riveted, the ends of the transom abutting against the inner vertical surfaces of the webs of the side frames and having flanges which pass between the upper and lower flanges of' the side frames to which they are riveted. The flange along the upper edge of the side frame projects over the pedestalspaces, and the pedestal-frames are secured to the ilanges at the upper and lower edges of the side frames, the upper member of the pedestal-frames passing over the projecting ends of the upper flange of the side frame, which, as above mentioned, extend across the top of the pedestal-spaces. The transom embraced in this application comprises two parall el channel-beams,an intermediate channelbeam horizontally disposed between and riveted to said parallel beams,and short channelbeam sections interposed between said parallel beams adjacent to their upper outer ends and riveted thereto and to the top ange of the side frames.

The invention will be fully understood from the detailed description hereinafter presented, reference being had to the accompanying drawings, in which- Figure l is a top view, partly broken away, 'of a portion of a car-truck frame constructed in accordance with and embodying the invention. Fig. 2 is a side elevation of same, partly broken away and partly in section, this figure illustrating two forms of pedestalframes, either of which may be employed at will, one being a modilication of the other. Fig. 3 is a vertical section through a portion of the truck-frame on the dotted line 3 3 of Fig. l, and Fig. 4 is a transverse section on the dotted line 4 4 of Fig. 2.

In the drawings,A designates the side frame or beam, having at its upper and lower edges the inwardly-turned iianges lettered B C, respectively, said iianges being substantially greater in thickness thanV the web portion of the side frame and being of a width about equal to the width of the guiding-surfaces of the pedestal-frames. The Lipper flange B of the side frame A extends outward across the top of the pedestal-spaces D, the projecting -ends of the flanges B being lettered E. The

pedestal-frames F are secured to the ends of the side frame A, and they are of suitable dimensions to receive the usual axle boxes and springs in the customary manner. The pedestal-frames F comprise the upper horizontal member G, the outer vertical member I-I, theA Aflange B of the side frame A, and is thereto secured by means of rivets or bolts N and the rivet or bolt O, the latter being centrally over the pedestal-spaces D and extending Vdownward through the outwardly-projecting end E of said flange B. At the right-hand end of Fig. 2 the lower horizontal member I of the pedestal-frame is formed 'by a bolt l?, passing through the sleeve Q and the outer vertical member H and the upper horizontal member G of said frame are in an integral piece or bar of wrought metal, as shown. The present invention is not, however, limited to the formation of the members Gr I-I in an integral piece nor to the use of the bolt P and sleeve Q as constituting the lower member I of said frame, and hence at the left-hand end of Fig. 2 I illustrate a form of pedestal-frame IOO in which the upper horizontal member G and the outer vertical member Il are in two pieces, detachably connected by the bolt R, and in which also the outer vertical member H and lower horizontal member l are in an integral piece, the inner end of the lower member l being connected with the vertical member K of said frame by means of the bolt S. The pedestal-frames shown in Fig. 2 are both of rectangular outline and are bot-h secured to the flanges of the side frame A in the same manner. The side frames A are rolled beams, and the upper and lower flanges B C thereof are of substantial thickness and specially formed to receive the pedestal-frames and the ends of the transom. The outer projecting ends E of the upper flange B of the side frame A impart great strength-and security to the pedestals and add to the efficiency of the truck-f rame as a whole. The rivet or bolt O passes downward through the upper member G of the pedestal-fram es and through the outwardIy-projecting ends E of the upper fiange B and binds said parts securely together. The ends of the web portions of the side frames A are in line with the rubbing-faces of the members K of the pedestal-frames; but since said web of the said frames is not equal in thickness to the width of the members of the pedestal-frame the auxiliary pedestal-piece T is secured through its flange V to the inner face of said web in order that the flange V of said auxiliary pedestal-piece may, with the thickness of the end of the said web, constitute a continuation of the inner side of the pedestal-frame partly formed by the member K of said frame. The auxiliary pedestalpiece T fills out the space at the ends of the side frame A between the upper and lower flanges B C of said frame and furnishes a suitable guiding-surface for the axle-boxes. At the upper end of each pedestal will be provided an integral inverted socket or receptacle X, which in use receives the upper end of the usual spring located above the axle-boxes, and said socket in the present instance will preferably be furnished with the end vertical gibs a and top horizontal gibs l) to engage the adjoining surfaces of the pedestalframe. The central portion of the sockets X will preferably be recessed or cut away to accommodate the head of the bolt or rivet O, as indicated. t

The transom (lettered Y) comprises the transverse parallel channel-beams d d, the intermediate horizontally-disposed channelbeam e, which is riveted along its edge -flan ges to the web portion of the said parallel beams, and the short channel-beam sections f, one being at each end of the transom and having its flanges turned downward and riveted to the web portion of the parallel beams d, while the web-surfaces of said beam-sections f are about on a horizontal plane with the upper edges of the beams d and pass below the upper flange B of the side frame, to which they are secured by rivets g. The transom at its ends lits between the lower and upper frames B C of the side frames and abuts against the vertical inner face of the web portion of said side frames, and said transom is secured at its ends to the side frames by rivets g, above referred to, which pass through the flange B and beam-sections f, rivets 7i, which pass through the upper liange B, and the upper horizontal flanges of the parallel beams (l, rivets t', which pass through the web portion ot' the intermediate channel-beam c and the lower flange C of said side frames, and the rivets j, which pass through the lower horizontal flanges of' the parallel beams d and the lower flange C of the side frame. Thus the transom is secured by vertical rivets or bolts which pass through the flanges B C of the side frame, which flanges are ot' substantial thickness and fully able to receive said transom. The intermediate beam c of the transom extends along the lower edges of the parallel beams CZ and hasits lower plain surface about on the same horizontal plane with the lower edges of said parallel beams, while its flanges turn upward and, as above mentioned, are riveted to the web portion of said parallel beams. It will be observed that the ends of the transom are of rectangular box-like form and are of great strength, rigidity, and durability. The box-like ends of the transom at their outer extremities snugly fit between the flanges B C and are securely riveted thereto, as above explained.

In the construction of truck above described the outer ends of the transom extend outward beyond the central vertical line through the rubbing-surfaces for the axleboxes, as indicated in Fig. l, said central line being represented by the dotted line m.
