b all whom it may concern:

Be it known that l, Calm Rondo, a citizen of the Confederation of Switzerland, residing .in New York, in the borough of lrianhattan, county and State of New York, have invented certain new and useful improvements in Jacking Apparatus for Railway- Gars, of which the following is a specification.

This invention relates to an improved jacking apparatus for railway cars or apparatus for lifting and shifting derailed cars with great facility back onto the tracks, said jacking apparatus forming a part of the that is sent to a place where a train is wrecked or car derailed, or that may be stored at larger stations for use in readily shifting individual cars from one track to another without the use of a turntable and shift-ing engine; and for this purpose the invention consists of a jacking apparatus for railway cars which comprises a transverse bar of suitable length that is applied across the bottom of the car, and two jacks, which are placed at opposite sides of the car and provided with means for raising or lowering the transverse bar, and with shifting the same, together with the car supported thereon, so as to lift, shift and lower the car to the track.

The invention consists further in the special construction of the jacks and the means for lifting the transverse supporting bar at one side or the other when a car is to be returned from a partly or entirely tilted position into upright position and then back to the track; and the invention consists lastly of certain details of construction of the lifting jacks, which will be fully described hereinafter and finally pointed out in the claims.

In the accompanying drawings, Figure 1 represents a side-elevation of my improved jacking apparatus, showing the same as applied to the bottom of a car for returning the same to the track, Fig. 2 is a vertical transverse section through the left -hand jack, taken on line Fig. 1, and drawn on a larger scale, Fig. 3.is a vertical longitudinal section substantially on line 3, 3, Fig. l, Fig. 4c is a ver ical transverse section through the right-hand jack, on line t, 4, a detail of the clamping device for the crank-shaft of the shifting device for the supporting bar, Fig. (3 represents a stirrup for permitting the lifting of the supporting bar independently of the lifting mechanisms of F ig. 7 is a upper part ing jacks.

Similar letters of reference indicate corresponding parts throughout the several figures.

Referring to the drawings, A represents a strong bar of suitable thickness and length, which is placed below the bottom of a car, near one truck of the same, and extended sufliciently at both sides of the same and through two jacking devices B, 13 which are placed at opposite sides of the track in proper position relatively to the derailed car which is to be returned to the track. The jacks B and B are equal in size and shape, and provided in their side-walls with recesses through which the supporting bar A is passed. Each jack is provided with an upright post 7, which is slotted at its middle portion for permitting the passage of the bar A through the same. The upper ends 7" of the posts f are guided in the toppart and thelower ends f in atransversebrace f at the lower part of the jacks. In the middle slotted part of the upright post f of the jack B is arranged a roller 1, which carries one end of the bar A, as shown in Figs. 1 and 2, while in the jack B is arranged, in the slotted portion of the upright post f, a gear-wheel g which meshes with a rack g atthe under-side of the opposite end of the supporting bar, as shown in Figs. 1 and Both jacks B and B are provided with lifting mechanisms for the upright posts f at their upper parts, said lifting mechanisms consisting of a rack (Z, at one side of the post f, a gear-wheel (P, a pinion (Z meshing with the gear-wheel (1, a crank-shaft cZ passing through the pinion (Z a ratchetwheel (Z on the outer end of the crankshaft, and a pawl (Z engaging the ratchetwheel and pivoted to the outer wall of the jacks for locking the posts in position when they are lifted by the lifting mechanisms operated by the cranks of the crank-shafts. The casing of the jacks B, B is made of wood, metal or other material and closed at the sides, ends and top. It is supported on a base-plate b, which is corners with screw-posts b the lower ends of which are screwed into foot-pieces b and provided at the upper ends with fixed handles for turning the posts and pro the jacks, and detail of the locking pin for the of the upright posts of the liftprovided at the' ducing thereby the leveling of the jacksy lower parts of the same, said plates bei-ng "turns in 'bearings of the y in the jack B enga ed by which passes through an ad ustable bearing plate 5 that is guided in a slot 9 in the the shaftg is provided with a hand-crank pinion and shifting the bar A to one side .or the other. The slotted portions of the upright posts f 'J'OtllllEtlS of the pinion lowered by the lifting mechanism at the lows the lifting or lowering motion, the lowering lllOflO-H for the purpose of holding the bar iii in the )roper position ready for the lateral shifting of a clamping screw g, which is swiveled throu h :the I end-wall of the jack and aided with athumb-nut g that engages the threaded end of :nut g presses the bearingplate against the side-wall of the oin 3' having a Q pin is passed through an opening in the :post f, as shown clearly in Figs. 3, 4 and supported thereon shifted car over the track. :plished the hand-pin lowered or mechanism.

according to the unevenness of the ground, so that the jacks are placed in vertical position. The sidewalls of the jacks B, B are hinged at their lower ends to. the baseplate 7) so as to permit the swinging of .the side-walls in sidewise direction for getting at the interior of the jacks for lubricating the parts and for repairing the same. The side-walls are reinforced by metallic cornerplates 7) which are bolted to the upper and In addition to the lifting and shifting devices, it is necessary to provide an independent lifting motion for either end of the carsupporting bar A. This is obtained by means of a stirrup i, which is shown in endview in Fig. 3 and in side-view in Fig. 6. The stirrup z is made equal in width, but longer than the supporting bar, and provided with a tapering or knife-edged portion 2' at the lower end so as to be able to engage the rack-end of the bar A. To the upper end of the stirrup 2' is applied \a swivel-eye into which is inserted an shaped "hook 2' at the end of a wirerope 2' that is wound ona drum 2' the shaft '2' of which turns in bearings of the front and rear walls of the casing of :the jack i. (On

the outer end of the shaft is placed a ratchetextended over the top of the casing, as shown in the different figures.

The shaft of the roller 1 of the jack B upright post f of the same, while the shaft of the gear-wheel turns in bearings of the er, said gear-wheel being the shaft of post 7'' of the lat a pinion 9 to permit the turning of the drum .in .one direction and lock the ratchet-wheel when the turning of the drum is interrupted. For :unwindingthe wire-.rope, t1=ie pawl is :moved out of engagement with the teeth of the ratchet-wheel. To the shaft 2' of the drum is applied a crank z' for winding vup .the wire-rope when the supporting :ba-r is ;to :be lifted at 'one end only, as in case when the car is turned over in partly .or entirely =ti-l'ted position. This permits the return of alihGcCklI into upright (position :as the ibar A is .used in -this.case'as1a lifting lever. then :the car is in upright position, the bar A :is applied transversely .under the bottom .of the same, in proximity to the truck, after which .the lifting .devices of both jacks :-are simultaneously operated, so that the .car is lifted by the supporting bar to the proper height above the trails. The lifting :posts are then looked in position, also :the .beari-ngaplate of the shifting mechanism. The :latter is then operated so as :to movethe,caiwoverithe track, after which the lifting :posts are unlocked and the lifting mechanisms lowered and .the car replaced on the track. "Vhen .the car-is replaced-on the track, the .jacking apparatus is then applied .to .the other .end of .the car and the sainexreturned to :the track in the same manner.

The improved jacking apparatus is ulsed as follows: iWhenever a .car :is derailed :by accident, a misplaced switch, .or for .any other :reason, the transverse bar A is placed at one end of theicariunder the bottom of the same, and through the jacks, one of which being placed at .one side of :the track --andthe other at the other'side 01f the track. The jacks are then .levelediup soiasztoassume a vertical position :by i-DlQLIlS of the screw- ;postsof the base-plates, after which atheicar front-wall of :the jack-. The outer end of g "by the turning of which the intermediate gear-wheel are operated for are provided with inclined oil-channels 0 for supplying "the lubricating oil .to the and gear-wheel shafts. hen the post f' of the jack B is lifted or upper part of the same, the bearing folsupporting bar following also the lifting or of the same. The bearing-plategj is clamped in position by means at .one end to :the bearing-plate g passed i is prothe screw as shown in Fig. 5. The turning of the thumb screwslotof the end-wall of the ack and holds it firmly in position. The upper end ofthe post f is supported-1n rigid position after ad ustment by a transverse handle at one end, which front-wall of the jack and through one of the holes f in the upper end of :the upright .7. \lVhen the posts of both jacks are thus supported in position, the shifting mechanism is operated and the bar A with the car for moving the WVhen this is accomf is withdrawn and released from thebearso that the posts f can be :raised again by the lifting the clamping screw :by lifting, shifting and lowering the car, ing plate 9,

then atithe.othersendiby the same operations. When :the car :has ;been partly .or entirely .ti1ted-.o.ver,--it has to ibejplaced ,first intoupwheel 2' which is engaged ibyia pawl i so as.

isfirst brought backyattone end'to the track right position. This is accomplished by placing the bar A. under the side of the car and lifting the car in connection with the bar A and the stirrup and wire-rope and winch of the jack B and the lifting device of the jack. After the car is lifted and in upright position, then the supporting bar is placed under the bottom at the end of the car and the jacks placed at opposite sides of the same, and operated as described for returning one end of the car after the other to the track.

The improved jacking apparatus for railway-cars forms a very useful device for complementing the usual wrecking apparatus sent out to the points where an accident to a train has occurred. It can also be used at larger stations, and even be carried along as an auxiliary in the baggage-car of express and other trains, so as to be always ready in case of accident when a car should become derailed and requires returning to the track.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:
