PATENT OEErcE,

JOSHUA H. ZINN, OF KINGSTON, TENNESSEE.

iIVlPROVEMENT lN WEIGHNG CARS.

Specification forming part of Letters Patent No. 55,916, dated June 2G, 1866.

To all w'hom it may coacemf Be it known that I, JOSHUA H. ZINN, of Kingston, in the county of Roane and State oi' Tennessee, have invented a new and. useful Improvementin Cars; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being' had to the accompanying drawings, forming a part ot' this specilication.

This invention consists in so arranging the bottom of freight or other cars as to rest upon the lever-frames of weighing-scales, arranged and constructed in any suitable manner to allow the contents orload ofthe car to be weighed, the frame ofthe car being constructed in any of the ordinary modes and sustained or supported upon trucks and wheels as usual with brakes arranged in the usual manner.

In accompanying plate of drawings my improvementin cars is illustrated, Figure 1 being a plan or top view ofthe weighing levers or frames, arranged in connection with the frame of the car, and Fig. 2 a vertical section taken in the plane ofthe line u: x, Fig. l, and in the direction of the length ot' the car.

Similar letters ofreference indicate like parts.

Ain the drawings represents the frame oi" a car, in the bottom of which, but above the plane of the trucks or running-gearof the ci l have arranged a system of levers or frames, B and O, such as are used in the ordinary platform-scales. One of these trames, B, extends the whole length of the bottom oi" the carframe A, or nearly so, turning at one end upon the upperside edge of the cross bar or brace D oi" the same, but connected at its other, through the vertical rod or bar E, with one end of the graduated lever or weighing-beam F, hung at or near one end of the car-frame at such height and in Asuch a position as to be most convenient for inspection when weighing', etc. This index or graduated bar or beam may be either arranged upon the outside or inside of the car and inclosed within a suitable box or casing provided with a door for opening or closing the same, so that the said beam can be examined when so desired.

The otherlever-frame, C, extends from the center ot' the car-trame bottom, or nearly so, (where it is pivoted at the ends ot' each of its arms G,) to the end of the car-frame at which the lever or weighing-beam is arranged, as above explained, where it rests and turns in a similar manner to the other frame, B, upon the upper edge of a cross bar or brace, H, of the car-frame J is a frame or box loosely fitting upon the inside oi' the ordinary box or frame otA the car and resting by its bottom K upon the leverframes B and O. In this inside box or frame, the bottom of which corresponds to the platform ot' ordinary weighing-scales, the freight or load is placed. It is intended that when this box or frame is empty it will exactly balance the weighing-pea of the scales at the lirst notch of the index lever or beam, so that, ii" the car is then loaded cit-her more or less, as the box J, in which the freight is placed, rests upon the lever-frames B and C, connected to such index-bar as explained, it is obvious that the amount of such load or freight can be weighed with the utmost readiness and accuracy, the same as with Ordinar f weighingscales.

To raise the weight from the weighing' levers or frames B and (J as the car is moving over the rails, so as to prevent all possibility of injury or damage occurringl to the weighing devices, I have arranged at each end ofthe car, and below the bottom ofthe loose inside box, a transverse shaft, P, having near each of its ends, upon the inside of the car-frame beams Q Q, a cam-shaped plate or disk, R, which disks, by turning such shafts in the proper direction through their handles S S, come to a bearing against the under side of the bottom oi' the inside box, and, raising it fromthe lever weighing-frames, remove its weight therefrom, transferring it to the main portion of the (airframe, these disks being held in such position by means ot' any suitable catch or other device which will keep their respective shafts from turning until disengaged when so desired.

Among the many advantages secured by my weighing attachment to cars, above explained, may be here mentioned as the most imporA tant that, lirst, the weighing can be accomplished with the greatest readiness, dispatch, and accuracy; second, that much expense in the weighing of freight is thus saved and the convenience. of performing it much increased; third, that for the weighing of coal, petroleum, and many commodities or merchandise, my improvementis of the utmost importance and advantage, for by a1.)plying my arrangement or any other suitable arrangement of Weighing devices to a car especially constructed for the carrying of petroleum, its Weight in bulk can be ascertained in a moment.

Although l have herein particularly described one mode of arranging a system of' Weighinglevers in'connection with a car so that the freight or load carried by the same can be weighed with accuracy, it is obvious that the arrangement of levers can be varied in many respects; and therefore I do not intend to limit myself to any one particular mode, the present invention consisting in so arranging a system of levers or framesin connection with the bottom of acar that the load or freight upon it can be weighed, either in part or whole, with the utmost accuracy.

I claim as new and desire to secure by Letters Patentl. The arrangement of the levers or frames B and C within the bottom portion of the frame of a car. and connected together and With any suitable Weighing lever or beam, in combination with the inside box or casing resting at each end upon such frames B and C, substantially as described,and forthe purpose specified.

2. The shaft P, having cam-shaped disks R, so arranged as to lift the inside box from the weighing levers or frames, for the purpose set forth.

The above speciiication of my invention signed by me this 23d day of December, 1865.

J. H. ZINN.
