-Application led November 27, 1908, Serial No. 464,752. Renewed November 11, 1911. Serial No. 659,842.
T0 all whom t may concern:-
Be it known that we, JOHN M. SNEAD and CAssrUs BRADY, citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Dumping- Trestles, of which the following is a specification.
The object of our invention is to provide efficient means for stacking coal or other material transported in dump cars.
We have illustrated our invention in connection with a dump car of a well-known type having a normally flat floor provided with drop doors hinged adjacent the longitudinal center of the car, but our 'improved apparatus may, without sacricing its advantageous features, be adapted to cars of different construction.
In the drawings-Figure 1 is an elevational view of one form of our dumping trestle. Fig. 2 is a fragmentary section 0n the line A of Fig. 1. Fig. 3 is a plan view. Figs. 4 and 5 are plan views of the dumping trestle, showing different arrangements of the tracks. Fig. 6 is a sectional view on line B B of Fig. 1. Fig. 7 is a sectional plan view of part of the structure shown in Figs. 1, 2, 3 and 7 Figs. 8 and 9 are a side and end elevation of a retaining block or chock for holding the cars in place upon the trestle.
The yard in which the coal or other Inaterial is to be stored is provided with a series of stationary railway tracks, and a portable trestle mounted upon wheels is used for the purpose of distributing the coal or other material. This trestle is provided with an inclined approach and a level elevated platform upon which railway tracks are laid, the tracks at the base of the approach being properly beveled to fit over the stationary tracks for the purpose of permitting cars to run from the stationary tracks up the inclined approach to the platform. The platform and approach are supported upon any suitable sub-structure, the
latter being provided with car wheels of thel ordinary form, in order that the entire structure may move along the stationary tracks. The elevated platform projects beyond the supporting sub-structure the projecting end being suitably braced therefrom. An inclined deflector slopes downwardly and outwardly from a point beneath the platform, in such manner that the part of the weight of the dumped material which acts normally to said inclined deflector will force the trestlev backward along the stationary track. By this means the weight of the dumped materials acts automatically to move the trestle away from the dumped material, thus securing a proper distribution thereof. The stationary tracks 1 are laid throughout the area where the material is to be dumped, preferably in parallel lines properly spaced to distribute the material evenly. The tracks may be surrounded by walls of any preferred height for the purpose of retaining the dumped material. In the present instance we have illustrated a low wall or curbing 25 running alongside of the tracks. These curb ywalls may be disposed as shown in Fig. 3, the tracks 1, 1a being arranged in pairs inclosed between such curbing with a single track 1d extending between the inclosures formed thereby.
The dumping trestle consists of a substructure mounted upon ordinary railway car wheels, and may if desired be built in sections 2, 3 and 4, each of the length of an ordinary railway car, and each of these sections may be provided with an lordinary swiveled truck, in order to facilitate the transportation of the trestle from place to place. When constructed in sections, any suitable means, such as bolts or rods, may be utilized for connecting the sections together when assembled for use. In Fig. 1
wehave shown the sections secured together by ordinary bolts 26. When the trestle is of double width, it is also preferably constructed in single track sections for convenience in transporting the same from place to place. Such construction is clearly illustrated in Fig. 6, where the right and left halves of the trestle are held together by timbers 27 and braces 28, suitable straps 29 and angles 30 being employed for the purpose of reinforcing the structure. Preferably, the elevated platform 5 is about fteen feet above the level of the stationary tracks 1, this being the maximum height to which it is generally desired to pile coal on account of the pressure resulting from piles of greater height. However, the height of t-he trestle may be diiierently adjusted forV different materials and different conditions. In the present instance we have shown the platform 5 projecting about half a car length beyond the base of the sub-structure, `the projecting end being supported by diagonal timbers 6. A bumper 7 is provided near the outer end of the platform 5, and from a point about a car length inwardly from the bumper, a deflector I8 extending transversely of the structure slopesV downwardly toward the end thereof. The projec-ting supporting timbers 6 are incased between side walls 9 and an end wall 10 as shown more clearly in Fig. 2. The side walls diverge from the timbers 6 to the deflec'tor 8, such divergence being provided for the purpose of facilitating the movement of the trestle away from the pile of dumped material, as in the absence of'such divergence there is a tendency on the part of the dumped material to tightly hold the structure against movement.
In order to dispense with the use of a locomotive for pushing cars upon the trestle,
and in order to render it possible to draw one car up at a time and to lower the same after being dumped, we mount upon the substructure of the trestle a motor 11, which maybe an electric motor or any other source of power. Geared to the motor is a winding drum 12, or two such drums in case the trestle is provided with two tracks, and a cable 1.3 extends from the winding drum over the sheaves 14 and 15 to the upper side of the trestle. Cable 13 is provided at its end with a hook or other means of attaching the same to a car. Sheaves 16 may be placed upon the upper side of the trestle-to carryy the cable and prevent it from contacting with the ties or rails. When the trestle is of double width, we preferably employ a single motor, as shown in Fig. 7, in which the motor is shown as operating throu h a train of gearing 31, 32,33, 34, 35 an 36. Suitable clutch mechanism is provided whereby the gear 36 may be connected to the adjacent drum 12 or to thev shaft 40 which is keyed to the opposite drum. Means are also provided for driving the pulley 41 from the gear 36 and anysuitable brake mechanism may be employed in connection with the winding drums and the pulley 41 by which the trestle is moved from place to place.
Inasmuch as the specific construction of the brake and clutch mechanism employed forms no part of our invention andV may be of any approved type, detailed description thereof will be unnecessary. The motor 11 may also be geared to one of the track wheel axles by means of a'chain belt 17, or other suitable gearing, for the purpose of moving the trestle from place to place.`
vIn Figs. 1, 2'and 3 we'show a'trestle of double width extending over two stationary parallel tracks'l, 1, Vthe trestle also being provided with parallel tracks 1b, 1c register-v ing therewith. In this form of the device, cross-over switch tracks connect the'parallel Ytracks upon the inclined part of the trestle,
and the motor is provided with two winding drums and two cables for the purpose of handling cars upon each of the tracks. In practice, when this form of trestle is used a line of filled vcars will be shunted upon one of the stationary tracks, for instance, track 1a. TheY cable 13a will then be attached to the end car, and by means ofthe winding e drum and motor this car will be pulled up track 1c to the elevated platform and there 4dumped by opening' the drop doors 20 shown in Fig. 7 The switch in track 1a being properly adjusted, the car will then be lowered upon the track 1, this track having been reserved for empty cars.
The single track trestle shown in Fig. 4 is adapted for use in those instances where 1t is not necessary to speedily handle a large number of cars.
The form shown in Fig. 5 may be operated in a manner similar to the double trestle'shown in Fig. 3, and will answer the same purpose except for the fact that a narrower pile will be discharged therefrom owing to theuse of but a Asingle track upon the elevated platform.
