DUMP- CAR.

Specification of Letters Patent.

Patented. Mar. 11, 1913.

Application filed January 1, 1911. Serial No. 603,332."

To all whom it may concern:

Be it known that I, THoMAs R. Mo- KNIcH'r, a citizen of the United States, residing at Aurora, in the county of Ixane and State of Illinois, have invented.certa1n new and useful Improvements in Dump- Cars, of which the following is a spec1fication, reference being had to the accompanying drawings.

My invention relates to dump cars and particularly to cars in which the bed 1s mounted to rock laterally to dump the load at' either side of the car and is provided with side-gates arranged to be moved or held up out of the way so as to permit the load .to be dumped.

My present invention relates more especially to the construction of the side-gates, and has for its object to provide a side-gate of improved construction which will make it practicable to use such gates on cars of large capacity. In dump cars of this type .as at present constructed the bed is comparatively shallow, and. in order to secure a bed vof large capacity it is necessary to make the bed of considerable length, and as it is objectionable to employ trusses or braces which project laterally beyond the sides of the'car ithas been a serious problem to construct side-gates of great length without using laterally-projecting braces or trusses and still secure the necessary rigidity. When it is considered that such sidegates may be from twenty-five to thirty feet or more long and only about two feet high the difficulties in the way of properly be appreciated.

I accomplish the object of my invention as illustrated in the drawings and as hereinafter described.

What I regard as new is set forth in the claims.

In the accompanying drawings,Figure 1 is an end view of a common type of dumpcar, showing my improved side-gate in end elevation; Fig. 2 is a plan view of about one-half of the side-gate; Fig. 8 is a side elevation of about one-half of the gate. showing the outer side thereof and Fig. 41 is an end view.

Referring to the drawings,5 indicates the body of the car, which is-pivotally mounted on the truck 6 in any suitable way so as to rock laterally. r f

.' I 34 indicates 7 indicates side-gates, which, in the con struction shown, are carried by straps 8-9 pivoted'to trunnions 10-l1 at. the ends of the side-gate.

12 indicates straps connected to the straps 8 and to straps 13 for holding the sidegates up when the body is tilted at either side of the car. side-gates are supported may, however,-be varied, as that forms no part of my present invention.

14-1516 indicates parallel beams or timbers which extend longitudinally and form the upper, intermediate and lower portions of the frame of the gate, as shownin Figs. 3 and 4:. 1718 indicate metal plates fitted to the upperand lower surfaces of the beam 14L, .said plates being of proper width to cover said surfaces. In like manner the upper and lower surfaces of the 'beam 15 are provided with plates 19-20, and the'surfaces of the beam '16 are provided with plates 21-22. The ends of the plates 17 to 22 are fixedly secured to end-plates 23, which, as shown in Fig 2, are in the form of angle- The manner in which the plates which overlie the ends of the beam 1et151-6 and the plates 17 to 22 and the sides thereof adjacent to the ends. The parts are all bolted together firmly so as to be secure. I also provide bearing plates 24 on the inner faces of the gate near the ends, as shown in Fig. 2. The trunnions 10-11 project through the angle-plates 23 and are fixedly secured to the upper and lower beams 1s-16 by bolts 25-26, respectively,

and are further secured by rivets 27-2S,

as shown in Fig. 3.

2930 indicate spacing-blocks which fit respectively between the plates 1819 and 20 and 21; as shown in Fig. 2.

31 indicates ,a series of vertical bolts which extend through the several beams 14-1516 and their respective plates and also through the spacing-blocks 29 30, and serve tobind the several parts of the gate rigidly together. The spacing-blocks 29-30 are preferably of about half the thickness of the gate,'as shown by. dotted lines in Fig. i

2, and for further bracing the several beams Iprovide channeled filler-blocks 32'33 at suitable intervals, as shown in Fig. 3, said blocks .being bolted, or otherwise firmly secured-to thespacing-blocks 29-30.

,vertical bolts, which pass is nevertheless thoroughly braced and supported from end to end without the use of trusses or bracing means-projecting out beyond the gate so as to interfere with the use of the car in narrow places.

That which I claim as my invention, and desire to secure by Letters Patent, is,

1. A side-gate for dump-cars, comprising a plurality of longitudinally-extending beams spaced apart, spacing-blocks fitted between said beams, end-plates securing the several beams together, vertical bolts con necting the several beams and spacingblocks, and trunnions projecting beyond the end-plates.

2. A side-gate for dump-cars, comprising a plurality of longitudinally-extending beams spaced apart, plates secured to the upper and lower faces of said beams, spacing-blocks fitted bet-ween said beams, endplates securing the several beams together, and vertical bolts connecting the several beams and spacii'ig-blocks.

3. A side-gate for dump-cars, comprising a plurality of longitudinally-extending beams spaced apart, spacing-blocks fitted between said beams, end-plates securing the several beams together, vertical bolts connecting the several bean'is and spacingblocks, and channeled filler-blocks fitted be tween the several beams and connected to the spacing-blocks, said bolts being fitted in the channels of said tiller-blocks. I

4. A side gate for dumpwars, comprising a plurality of longitudinally-extending beams spaced apart, spacing-blocks tit-ted between said beams, anglcpla.tes connecting the end portions of said beams, vertical bolts connecting the several beams and spacing-blocks, and trunnions projecting be ond said angle-plates.
