RAILWAY FRElGHT CAR.
SPECIFICATION forming part of Letters Patent No. 412,964, dated October 15, 1889. Application filed June 25, 1389. Serial No. 315,561. (No model.)
To all whom, it may concern.-
Be it known that I, CHARLES MACKALL, re-
siding in the city of Baltimore, State of Maryland, have invented a new and useful Improvement in Railroad Freight-Oars, of which the following is a specification.
My invention relates to improvements in railroad freight-cars for conveying merchandise in bulk in conjunction with apparatus for dumping and shooting material, by gravity, from cars into carts, bins, dumps, or other receptacles; and the ob jects of my improvements are, first, to elevate the body of the car to a sufficient height to allow the material contained in the hopper or body of the car to be transferred by gravity into another receptacle alongside of the track on which the car is standing; secondly, to enable me to operate one or more hoppers on the same car inde pendently of each other; thirdly, to properly guide the hopper while it is being elevated and without causing undue friction on the parts; fourthly, to regulate the discharge of the material in the hopper so that in the case of small grain and this character of material the opening through which the mate rial passes out may be closed at any time erregulated to discharge more or less in quantity, as may be desired; fifthly, to provide a mechanism that will give in the least compass and minimum friction the largest translation of power, thus enabling me to elevate the hopper loaded, with asmall application of hand-power. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure l is an elevation showing one-half of the car in length, one hopper, and the half of another with a portion of the intermediate part removed, disclosing a part of one of the elevating screws and nuts beyond. Fig. 2 is a plan view, one half shown in section and the other half outside looking down on the car, with an inverted view of a portion shown broken away, illustrating the slide in the dump-door. Fig. 3 is an end view of the body or hopper of the car, showing the vertical screw, nuts,worm and wheels, and thrust-bearing boxes for screws. Fig. 4 is a detailed view, on a larger scale of the screw, nuts, binders, and connections to transverse beams.
Similarletters refer to similar parts throughout the several views.
The posts D and C, the channelconnectingirons T, transverse channel-iron beams E, and the I-beams V constitute the upper frame-work of the car. These parts are allstrongly knee braced to each other and to the sills of the car, forming a rigidly-constructed structure, and in addition have diagonal tierods P passing from the sills to the cornenposts, to which they are secured at their heads. Composition nuts F are secured to the ends of the hoppers with female threads, through which freely revolve vertical screws G, these screws being held in position by bearings H and prevented from rising by thrust collars Y. At the lower ends of the screws wornrwheels are provided, into which pinion-worms are geared and keyed onto horizontal shaft X, said shaft being operated by ratchet-levers N and confined in bearings. Sliding doors are provided on the top of the hoppers at U for receiving freight. Anti-friction rollers K and V, working in guides 011 one side, are provided to take the strain off the screws while holding the hopper in a vertical position. At the bottom of the hoppers a dump-door R is provided with a three-parted slide working across parts on the face of the dump-door by means of a screw and hand-wheel, regulating the discharge of material.
From the aforesaid description it will be seen that the effect of operating the ratchetlever N is to turn the horizontal shaft, with its two attached worms geared into the wormwheels L, causing the wheels to revolve in a horizontal plane, and as the wheels are keyed to the lower ends of the upright screws these screws simultaneously revolve in their bearings H and the nuts F, attached to the hoppers, thus causing the latter to be elevated, while the thrust collars on the screws working against the binder-boxes fixed to the cross-beams prevent the screws themselves from being either raised or lowered.
As I am aware, by my patent, No. 402,174,
dated April 30, 1889, I have already been a1- lowed a claim for the combination. of a car having a hopper bottom and gate at the apex thereof, independent framework, and. car
frame for raising and lowering the car-body. I do not, therefore, claim this part of the combination here; but i What I do claim, and desire to secure by Letters Patent, is
1. The combination, in a freight railroad- 'car for hauling material in bulk on railroads,
of a horizontal shaft secured to frame-Work, With Worm and ratchet lever communicating and transferring power to Worm-Wheels, and upright screws revolving in nuts secured to hoppers or detached bodies of cars independent of each other and unattached to the frame-Work of the car, exceptby the aforesaid screws, permitting vertical motion only.
2. In a dumping freight-car Where the hop-v pers are independent of the frame-Work, the
combination of anti-friction grooved and
