DAVID MORITZ, OF BLACK ROOK, (BUFFALO,) NEW YORK.
IMPROVEMENT IN JACKS FOR REPLACING CARS.
Speoicatiou forming part of Letters Patent N o. 118,965, dated September 12, 1781.
To all whom it may concern:
Be it known that I, DAVID MORITZ, of Black Rock, (Buffalo,) in the county of Erie and State of NewYork, have invented a new and Improved Traversing-Jack for Replacing 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 drawing forming part of this specification, in which- Figure l represents a sideelevation, partly in section, of my improved traversing-jack. Fig. 2 is a plan or top view ofthe same.
Similarletters of reference indicate correspondin g parts.
This in-vention relates to anew apparatus which is to be applied to railroad cars, for the purpose of replacing` the same upon the rails when they are run off the track. The invention consists in the construction an d arrangement of certain parts as hereinafter described and claimed.
A in the drawing represents a portion of the car-body. B is a bed-plate, on which the crosshead or bar-shaped frame O, attached to the jack, is to traverse. The cross-head is provided with double flanges which embrace the parallel rails or sides ct a of the bed-plate, and is preferably provided with friction-rollers b b to facilitate its movement. Both the bed-plate and cross-head are suspended from the ear by the jack D. The screw z of the jack works in the nut c that is aiIiXed to the car-body. The nut is swiveled in a shell, d, that is affixed to the car, and is, by toothed wheels e, connected with an upright shaft, E, which carries a hand-wheel, j'. By turning this wheel the nut will be revolved to work the screw up or down, and thereby raise or lower the jack. A ball-joint, g, forms the connection ofthe nut with the cross-head, permitting the jack to rest in an inclined position on uneven ground. From the ear is also suspended, by ball-joint h,
a vertical shaft, F, which passes through a pinion, t', that hangs between earsjj of the cross-head. The pinion@- meshes into teeth m, that are formed on the inner side of the bed-plate. The shaft F can slide up and down in the pinion, and connects by feather and groove with the same. rThis connection enables the car to be elevated without throwing the pinion out of gear.
The operation is as follows: When a car, having a jack, D E, near each end, runs off the track, the bed-plate at the off end is lowered by means of the screw, and after it has reached the ground the nut is still turned to raise the wheels of the ear from the ground. The end of the car is then entirely supported by the jack. By next turning the shaft F, by means of a handle, I, fitted to its upper end, as in Fig. l, the pinion will roll along the rack m, and carry the cross-head and end of the car horizontally until the wheels of the latter are again above the rails. The car is then again lowered upon the track, and the bed-plate raised off the ground. The nut can be locked, to hold the bed-plate elevated, by means of a pawl, n, catching into a ratchet-wheel, 0, on the shaft E. The handle Z is removed from the shaft F and the latter locked, to prevent its turning, by a plug, p, fitted into its grooved upper end.
Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The cross-head G, suspended by ball-joint from a screw, z, and connected with the oedplate B, substantially as herein shown and described.
2. The shaft F, suspended by ball-joint from the car, and tted loose through a pinion which hangs on the cross-head O, and meshes into a rack on the bed-plate B, substantially as herein shown and described.
DAVID MORITZ.
