RAILWAY-CAR-TRUCK FRAM E.

SPECIFICATION forming part of Letters. Patent No. 588,580, dated August 24p., l l Application filed April 5, 1895. Serial No. 544,602. (No model.) A' A f' To all whom, it may concern,.-

Be it known that I, GEORGE ROBERT .TOUGH- INs, residing at Berkley, in the county of Norfolk, State of Virginia, have invented a new and useful Improvement in Railway-Car Trucks, of which the following is a specification.

My invention relates to improvements in metal railway-car-.trnck frames; and the obro jects of my improvement are, first, to construct a strong, durable, and cheap frame; second, to form a jaw or pedestal for the reception of the journal-box in a novel and effective manner.-I'attain these objects by constructing,truck-frames as shown in the accompanying drawings, in which- Figure lis anl elevation; Fig. 2, a half-plan of the truck-frame; Fig. 3, a section through 93 and Fig.K 4 an elevation showing formazo tion of the upper part of the pedestal.

The truck'- frame is constructed of four main pieces,each consisting of a rolled beamvlz., the side frames A and the transoms B, attached by an angle-iron or other form of z 5 brace O, connecting their webs together. The side fram es have their ends bent upward and cut out to shapehasshown in detail in Fig. 4,

to form the upper part of the pedestal-space and to give alnple strength to the side frame 3o above the journal-box, while providing sufcient space for a spring-pockenthe springs F being placed above thejournal-boxes. rI he pedestals E are made of T-irons riveted to the side frames and may be prolonged upwardaround the top of the pedestal above spring-pocket, as shown on drawings at G,'to reinforce the fram e, which at that point forms the topof the pedestal.

The pedestal shown in the accompanying 4o drawings is claimed in my application` for Letters Patent on railway-car-truck frames iiled December 12, 1894, Serial No. 531,586.

In all previous rolled-beam side frames for trucks which have'been used or proposed the beam has been shallow, of sufficient depth only to sustain the weight. In this truck an important feature of the invention is that I make the side frame deep, not only to obtain strength, but to cheapen construction and to 5o enable suitable pedestals tobe formed.

I am aware that a pressed-steel truck-,frame f has been patented by D. L. Barnes possessing the same'general outlines as thetruckframe described in this myspecication ,j but pressed-steel truck-frames have been objected to because the flanges of the side frames and transoms cannot be made with v sufficient thickness and of suitable form to give the desired strength, while in my invention it is apparent that any known form of 6o rolled beam may bev used, that'the flanges can be made any form or thickness desired, and that the expense of cutting out plates to form frames and of anging them is done away with, thus admitting a Vstronger and cheaper truck to be made. 1

It is apparent that a vertical pedestal having an opening at the bottom only may be used Without departing from the nature of my invention.

What I claim asmy invention, and desire to secure by Letters Patent, is-e- 5 l. A side frame forv railway-car trucks formed of a commercial r lledfbearn` having the lower flange, the web, andthe "upper 75 flange bent upward, and a portion of the lower flange and web cut away'so as to form pedestals, substantially as described.

2. A car-truck frame composed of the parallel continuous metal side beams having the 8o pedestals formed within their ends and which are open at their outer sides, combined with removable pieces to iill the open outer sides of said pedestals, and a metalbeam transom connecting said side beamisand'rigidly'se- 85 cured thereto, said pedestals being of sufiicient height to permit the ljourn'al-boxes to have a vertical play within themgysubstantially as set forth. Q Y y 3. In a car-truck, theparall'elcontinuous 9o metal-beam side frames, and apedestal-frame at each end of each-side frame, each pedestalframe having its upperpart, one side and spring pocket applied 'substantially within and attached to the webbf theside frame 95 and having its outer vertical vside in a movable piece connected with'the web 4of the side frame, combined with abeam connecting said side frames; substantially as described.

4. In a car-truck the rolled flanged contin- Ico nous parallel beam side frames, and a pedestal at each end of each side frame and of 'a height sucient to permit the vertical movement therein of the axle-boxes, the outer vertical side of each pedestal having a movable piece, combined with the continuous rolled flanged parallel transom-beams extending transversely across the truck between said side frames and rigidly secured thereto, the axleboxes in said pedestals, and springs yieldingly resisting the upward movement of said boxes in said pedestals 5 substantially as 'set forth.

V5. The T-iron attached to the web of a commercial rolled-beam side frame and prolonged downward to form the lower portion of a pedestal, substantially as described.

`G. In a car-truck, the continuous parallel metal-.beam side frames, the .ends of said beams having therein the pedestals provided with spring-pockets and open at their outer sides, combined with movable pieces for the outer sides of said pedestals, an d a beam connecting said side frames/and secured thereto; substantially as set forth.

7. In a car-truck, the parallel continuous metal-beam side frames, and a pedestal substantially within each `end thereofand formed on one side `bya guidin g-pieceiattach ed `to said weband on the other side by a movablepiece, the pedestals heingof sufficient height t0 permit vertical movement .of the `journ.al-boxes, combined with a beam .connectingsaidsides; substantially as set forth.

`8. In a car-tru ck the metal-beam side frames having the pedestal-spaces fashioned within the ends thereof, said pedestal-spaces being` open at their outer sides and of a height 1o permit the vertical movement of the journalboxes therein, combined with the `rubbingpieces `along the 4inner vertical edges of said spaces, the outer movable rubbingpieces closing the outer sides of said spaces and a transom connected `at its ends to the webs of said side frames; 4substantially asset forth.

9. In a car-truck, the continuous parallel metal-beam side frames having the pedestalspaces fashioned within the ends thereof, said pedestal-spaces being permanently closed at the `bottom and open at the outerside and being of a height to permit the vertical movement of the journal-boxes ztherein, combined with the `rubbing-pieces along the inner vertical edges of said spaces, a movable rubbingpiece `closing the outer vertical side of .said spaces and a beam connecting said side frames; substantially as set forth.

l0. In a car-truck, the parallel continuous metal-beam side frames each having within the web at its ends the pedestal-spaces .to receive and permit the vertical movement of the axle-boxes, combined with `a beam connecting said side frames, and the pedestalframes applied to close said spaces and attached to said web and one section of which is movable to permit the escape of said boxes, said pedestal-frames cach having one vertical side and the lower side in a continuous integral piece, and the other vertical side in a separate piece; substantially as set forth.

ll. A car-truck comprising the connected commercial rolled-beam side frames having their ends bent upward and a portion of said ends cut away to form pedestal-spaces for the axle-boxes, and pedestal-frames secured to the web of said frames for said boxes; substantially as set forth. y

l2. In a car-truck, the parallel continuous metal-beam side frames, and a pedestal at each end of each thereof and formed on one side by a guiding-piece attached to vertical web of said side frames, and on the other side by a movable piece, the pedestal being of suflicient height to permit vertical movement of the journal-boxes, combined with a beam-connecting said sides; substantiallyas described.

13. A car-truck fra-mecomposed `of the parallel continuous met-al side beams, and metalbeam transoms connecting said side beams and rigidly secured thereto, in combination with a pedestal attached to `the `webof said side frame and having an i-openingat itsside, a removable pieceof metal to close saidopening, a journal-box moving vertically within said pedestal, `and coiled metal springs insented abovethe journalboxes,and within the pedestals., substantially `as described.

14T. In a car-truck, the parallel continuous metal-.beam side frames, and a pedestal at each end of each side frame, each pedestal having its `upper part, Lcontainingfa springpocket, and one side attached to `the web of the side frame, and its other side and lower part formed by a metal pedestal-frame also Aattached `to said web, combined with a beam connecting said side 'frames and secured at its ends `thereto and the movable piece `completing the outer vertical side of said pedestal; substantially as set forth.

15. In a car-truck, the parallel continuous metal-beam side frames, and a pedestal at each end of each side frame, each ,pedestal having its upper part and one side attached to the web of the side frame, and its other side and lower part formed by a metal `pedestal-frame also attached -to said web, combined with a beam connecting said parallel side beams and secured at its ends thereto and the movable piece completing the `outer vertical side of said pedestal; substantially asset forth.
