SPECIFICATION foxriiciinhg.:part of Letters vPatent N o. 711,420, datedOctober 14, 1902.

Application filed June 10,1902. v Serial No. 110,999. (No model.) I

1'0 all whom it may concern:

Be it known that we, JOHN H. FARLOW, 1'e siding at Baltimore, and GEORGE SCHIMPF, residing at Curtis Bay, in the county of Bal timore, State of Maryland, citizens of the United States, have invented certain new and useful Improvements in Dumping-Gars, ofj

i which the following is a specification. The object of our invention is the produc- Io tion of a dumping-car which shall have a single body supported upon two pairs of wheels and adapted to tip'sidewise and dis! charge the load beyond and outside the trackrails, which shall have an improved frame upon which the body is pivoted, which shall be provided with improved means for operating the door or gate in such a manner that the said door will be swung a greater distance than usual from the body to allow the free discharge of coarse material, and which shall possess other and desirable novel features of construction, constituting -the same'a superior instrumentality for performing the requisite functions of apperfect dum ping-car. Our invention consists in certain novelties of construction and combinations Y.of parts hereinafter set forth and claimed.

In the accompanying drawings, which form a part of this specification, Figure 1 is a plan of 3o a du mping-car embodying our invention, onehalf of the tilting car-body or that portion to the left of the line xx, Fig. 2, being removed, showing the truck below the same. Fig. 2 is a partial side and partial sectional view on' i line y y, Fig. 1. Fig. 3 is an end view, the car being in tilted position. Fig. 4 is an end view, the car being in horizontal position.

Similar numerals indicate like parts in the several figures of the drawings.

The numeral 1 designates the frame of the truck, said frame being of the diamond style and supported upon coiled springs resting upon thejournal-boxes.

6 designates the wheels and axles.A

2 designates extensions of the'frame; 3, metallic channel-bars with fillings supported upon and secured to the projecting ends of the frame.

7 designates longitudinal beams resting 5o upon the channels 3, as shown; 8, three crossarm 18, also pivoted to the gate 17.

beams; el', braces of iron bentto shape and eX- tended overbeams 7 and secured to the ends of the channel-beams.

9 designates castings supported upon the beams 8 at one side of the longitudinal center '55' of theframe, and 10fth'e perforated dauges orears of the castings.

To the under side of the car-body and extending longitudinally of .theftruck is rigidly secured a beam'12, to which are fastened the 6o depending perforated castings 13, which ft between and are pivoted to ears 10 10 of the castings 9, so that the car-body can be tilted or rocked upon the cross-beams 8 8 8.

On each of the opposite sides of the carbody adjacent the ends of the truck isrigidly secured a bar or strap 14, which is provided with an outwardly-projecting upper portion. On the inner face of. said upper -portion and the upper endthereof is pivoted 7c a bar 15. 'To one end of each of said bars 15 is pivotedv one end of an upper arm 16, which the gate 17 of the car-body, while to the other end of each of said bars 15 is pivoted a lower 75 Itwill be noticed that the arms 16 are pivotally connected to the gate 17 at or near the upper edge and at opposite ends thereof, while the arms-18,v which are. also longer than the arms 8o 17, are pivotallyconnected to said gate at or near'its lower edge on the opposite ends thereof.

Pivotally connected to each of the arms 16 and intermediate of its ends is an arm19,

which is also pivotally secured to an upper projecting endof a bar 20, rigidly secured to the under side of the beams 7 of the truck, whereby a firm support is furnished for the same. To the pivotalconnection of eacharrn oo 16 with a bar.15 is pivoted one end of a link 21, the' other end of said link being slotted at 22 and movable on a headed stud or pin 23, projecting from an arm 19 through said slot.

To sustain the car-body 11 in horizontal po- 95 i sition, a longitudinally-extending beam 24 is provided. The said beam is supported between pairs of strap-irons 25, which are firmly secured to the cross-beams 8.

A locking device to firmly hold the car-body Too in its horizontal position consists of a bar or turnbuckle 26, with a chain or other ilexible extension 27 and a hook 28, the latter engaging with an eye 29 on the car-truck, while an eye on the upper end of the bar 26 engages a hook 30 on the car-body. A link 32, connecting with the chain 27 and passing over the end of the hook 28, prevents the latter from accidental disengagement.

The outer ends 33 ofthe channel-beam crossbars are beveled on their upper faces to serve as supports as well as stops for the car-body in its tilted position.

It will be noticed that owing to the construction of the gate-arms as described and shown even when the hook 28 is disconnected from the eye 29 of the truck, the arms 15 and 16, which form a toggle-lever, being in the same line, some force is necessary to tilt the body 11 upon its pivots and away from its supporting-beam 24. However, as force is applied so as to lower the right-hand side of the said car-body the gate 17 will be moved outwardly, the lower end thereof farther than the upper and away from that end of the carbody, the arms 15 turning on their pivotal connections with the bars 14E, so that they are out of line with the arms 16, and at the same time links 21, owingto the decreasing distance between the arms 15 and 19, move on the pins 23, so as to occupy the position shown in Fig. 3 or in the opposite end of the slot from that shown in Fig. 4, thereby locking the arms from further movement in that direction. When the car has been emptied and its lower end is lifted, the toggledever, composed of arms 15 and 16, is straightened out, and owing to the increasing distance between the arms 15 and 19 the links 2l move on the pins 23, so

as to occupy the position shown in Fig. et, the` pins 23 being in the lower ends of the slots or in the opposite ends from what they were when the car-body was in tilted position. When in the position shown in Fig. 4C, the

links 21 normally aid in keeping the arms l5 l and 16 in right line or extended position. When the car-body is in horizontal position and supported on the beam 24, the locking device, consisting ofthe bar 26 and connected parts, and which is readily detachable from the car-body and truck, prevents the accidental tilting of the body.

By having the parts so proportioned that the lower edge of the gate projects out farther than the upper edge when the car-body is tilted and having the gate above or entirely clear of the open end of the car-body during the dumping of the car the liability or danger of large masses ot' coal or other contents of the car coming into contact with the said gate is avoided, thereby lessening the 'chance of damage thereto.

The car-body itself has several novel features of construction. The bottom boards are secured directly to the beam 12, the sides supported by the channelbars with bent ends All, secured to the ends of beam 12, and the ends of the sides are joined tothe floor by bent angle-irons 45, which prevent the ends,and especially the open end,from spreading. The floor edge projects at 46 beyond the angle-iron and supports the gate or door when closed. It will be observed that the beam 12 and the pivotal castings are supported upon the cross-beams 8 of the frame at one side of a longitudinal line through the center of the truck-frame, so that when the body is tilted its edge will project beyond the track-rail and frame and discharge the load relatively far outwardly from the same. The body itself in this example is not centrally secured to the beam 12, but one side of the longitudinal center thereof, the disposition being such that the part thereof upon the same side as the support 24: will be of greater weight than the opposite side. As so constructed and arranged the body will when empty remain in its horizontal position and can when tilted be more easily returned to said horizontal position.

We have shown the frameof the truck prop so as to greatly lessen any danger thereto` from contacting masses of the said contents. The arrangement of the pivotal points of the dumping mechanism to one side of the longitudinal central line of the frame l permits the load to be discharged outwardly beyond vthe track, and the disposition of the car-body upon the beam 12 at one side of its center facilitates the return of the body from a tilted to a horizontal position and in retaining it in said latter position. H l

Numerous changes in` the details of construction may of course be introduced in the manufacture of the car without constituting a substantial departure. We have shown the angle-bars 2O secured to the beams 7, the ends thereof bent upwardly, and a tensionbar 40 secured to the said bent ends and to the beams 7, the supporting-beam 24 extending the entire length of the truck-frame, and the truck-frame itself supported upon journalbox springs. While these and other specific details of construction are preferable, modifications may be employed to perform the same functions and which will not be considered colorable in their nature.

Having thus fully described our invention, what we claim as new, and desire to secure by Letters Patent, is
