GONDOLA FREIGHT-CAR.

SPECIFICATION forming part of Letters Patent No. 695,623, dated March 18, 1902.

` Application iiled December 20, 191. Serial No. 86,700. (No model.)

To all whom, t may concern:

Beit known that we, THOMAS J. NEWBEERY and JOHN V. ERICSON, citizens of the United States, residing at Chicago, in the county of Cook and Stateof Illinois, have invented certain new and useful Improvements in Gondola Freight-Cars, which are fully set forth in the following specification, reference being had to the accompanying drawings, forming a part hereof, andin which- Figure l shows our said new car in front elevation, of which the right-hand half shows an exterior View and the other half an interior View, with some parts in section and the various operating parts in both broken and entire outlines for the purpose of showing their manner of operation. Fig. 2 shows'our said device in plan View with some of the doors removed, some open, and someclosed. Fig. 3 shows our car inside elevation with a fragment thereof in section between one pair of frames A and the other parts provided with` compound doors, shown closed at other sections. kFigli: shows a front 'elevation of a fragment of a transverse frame A of the carbody with a hinged discharging-bottom or trap-door in closed position, also in open position in broken outlines. Fig. 5 shows a front elevation of a fragment of a transverse frame similar to that shown in Fig. 4, having a like hinged bottom, but locked by a different kind of mechanism. Fig.`6 shows an en-` tire transverse frame in front elevation on a smaller scale, together with a vertical longitudinal section taken through its center. Fig. 7 shows a right-hand end bar of any' of said transverse frames provided with a locking mechanism for the discharging-doors g. Fig. 8 shows in sidev elevation mechanism` to operate'gthelever locking and releasing mech-` 'formed a very strong such beamsand that of the U pattern, as

shown in Fig. 1, onand around'which we build the bottom of our gondola. Said bottom is preferably of' cylindrical section, as shown, because of the most desirable form both for strength and convenience of construction, also to secure by our said form a lower center of gravity for the load than is obtained in the usual form of construction having either l[iat or longitudinally-arched floors; and our invention also consists in dividing the box or body of our car into sections or parts provided with side doors, either single or compound, from which the load may be discharged in suitable quantities, and other advantages hereinafter to be set forth. To attain said desirable ends, we construct ourimproved gondola substantially as follows, namely:

` In the drawings, in Fig. 1, are shown two U-beams b, having their plain sides facing toward the center-line and extending from end to end of the icar-body. Between said beams b is thus provided a convenient place for the draw-head and other draft-rigging. Over the tops of the beams o is secured a cylindrical section c of sheet-steel to form the fixed bottom of the gondola boXf. The outer edgesof said section c extend below the tops of the wheels, as near as may be to their axles, and under said beams b is secured a bracing-plate d, which rises upward from the foot of each beam to meet the cylindrical bottom and to which its ends are attached. Said bracing is shown in end view in broken lines in Fig. 3, and in this case is shown over the saddle-bar a ofthe truck; but there may` be as'many such braces as may be deemed necessary, or, in fact, said part d may be ex- 1 tended both ways to the full length ofthe cylinder c,- andv thus form 'an additional strengthening to the bottom c. yThe outer edges p of the cylinder c are turned out at about right angles to the flanges n or parallel to the ends of said iianges, as shown at 1J in Figs. 1, 4, 5, 6, and 7. By means of said cylindrical arch and beams thereto there is yet light gondola bot,- tom.

The frames A consist of two vertical stays e, T-shaped in cross-section, which are connected by a web o', having a top flange 'n' and an arched bottom flange o, iitting on the cylinder c and to which said flange is secured. A bottom 'n2 is laid either on or between the flanges fa', and said bottom has openings provided with trap-doors m, hinged at q, as shown in Figs. l, 2, 4, and 5, and said doors maybe held up at their free ends by a hook 7a2, Fig. 4, provided with a lever it', which is held in its place by a pivoted stop 7c3. The preceding form of holding mechanism for this trapdoor is used when the load is to be carried on the level bottom n2. Said trap-doors may be lowered into the position indicated in broken lines in Figs. l and 5 when the side doors g form a part of the structure. In the latter case when the doors g are opened the doors m drop from the bracket g2 and the load is discharged, or the trap-doors may either be omitted entirely and the load carried on the cylinder c when the side doors g are used. In Fig. 2 the trap doors m are shown taken out of the first sectional spaces, and the right and left hand parts of the cyl inder c are shown. In the other" sectional parts the doors on are shown closed. Said side doors g may also be formed into compound doors by the use of smaller or secondary doors h over openings through said primary doors, through which small portions of the load of their sections, into which our carbody is divided by our cross-frames A, may be let out, as when it may be desired to load only a small Wagon, and larger loads may be let out by using both small doors together or in part only, and finallyall the doors g may be opened for the discharge of the entire load on either one or both sides of the car. Said doors g are hinged at Z and theiroppositc edges are held by anysuitable means, as by hooks j on a hingej, secured on the under side of the bottom c. To said hooks jare secured operatinglevers t,whose free end is held and released by a reciprocable bolt T5, secured to the vertical rib of the stay, as shown in Figs. 5 and 7. Said boltq'5 is connected to a bell-crank lever r1, which in turn is connected to a reciprocable bar r3, of which one end is connected to an arm r2 on the end of a shaft r at one end of the car-body, and to said shaft is secured an operating-lever r', by means of which and in one movement thereof all the doors g, either on one or both sides ofthe car, may be opened sim ultaneously,as may be desired. The small doors h on said doors g are here shown locked with a button fi. The stays e are bent at about the floor-level n2 to project inward, as shown at e', and the box sides of the boxf are held by said two parts e and e. The broken lines 't in Fig. l are to indicate how the central part ot' the bottom n2 may be raised for the more complete discharge of its load through the bottom of the car. The flanges u' are but a continuation of the llanges n of the stays c, forming a part of the web o of the frame A.

What we claim isl. The combination with longitudinally central beams, extending from truck to truck, of a cylindrical bottom attached directly to said beams, substantially as specified.

2. The combination with longitudinally central beams, extending from truck to truck, of a cylindrical car-bottom, secured directly to said beams, having its side edges below the wheel-tops, substantially as specified.

3. The combination with longitudinally central beams, extending from truck to truck, and a cylindrical car-body bottom, attached directly to said beams, having its edges below the wheel-tops, of a car-body having discharging-doors with free edges locked to said side edges, substantially as speciiied.

4C. The combination with longitudinally central beams, extending from truck to truck, and a cylindrical car-body bottom, attached directly to said beams, having its side edges below the Wheel-tops, of a car-body having discharging-doors whereof their free edges are locked to said side edges, and means to lock said doors to said edges, substantially as specified.

5. The combination with a cylindrical carbottom having its side edges below the wheeltops, of a car-body with compound discharging-doors immediately above said edges, substantially as specified.

6. The combination with a cylindrical carbody bottom, of a fiat bottom with closable openings through it above said cylindrical bottom, substantially as specified.

7. The combination with a car-body having a cylindrical bottom, of a iiat bottom above said cylindrical bottom having closable passages, side doors to hold said closures and means to operate said doors, substantially as specified.

8. The combination with a car-body having a cylindrical bottom and transverse frames dividing said car-body into sections, of discharging-doors immediately above the edges of said bottom, substantially as specified.
