UNITED STTE$ PATENT QFFIQE- ADAM WOJTKIEWIGZ, 03E RANSHAV, PENNSYLVANIA.
CAB-REPLACER.
Application filed November 13, 1919.
To alt whom it may concern:
Be it known that I, ADAM lVoJrnniwioz, a citizen of the United States of America, and resident of Eanshaw, in the county of Northumberland and State of Pennsylvania, have invented certain new and useful Improvements in Car-Replacers, of which the following is a specification.
This invention relates to jacking apparatus and particularly to means for raising railway rolling stock and moving it so that the wheels thereof aline with a track in on er that the rolling stock may be replaced er derailment. n
.r-l-n object of this invention is to provide novel means whereby railway rolling stock such as a car may be jacked up or elevated and then moved for the purpose stated, means being provided for permitting the supporting member to move relative to the frame or means for holding it, all as will presently appear.
With the foregoing and other objects in view, the invention consists in the details of construction and in the arrangement and combination of parts to be hereinafter more fully set forth and claimed.
in describing the invention in detail, reference will be had to the accompanying drawings forming part of this specification, wherein like characters denote corresponding parts in the several views, and in which- Figure 1 illustrates a view in elevation of a jacking device emboding the invention;
Fig. 2 illustrates a top plan view thereof;
Fig. 3 illustrates a sectional view of the jacking frame disconnected from the truck;
Fig. l illustrates a sectional view of the jacking frame showing a truck in elevation for transporting the said jacking frame;
Fig. 5 illustrates a perspective view of a fraqment of the truck; and
Fig. 6 illustrates a sectional view of a rail showing a clamp thereon.
In these drawings 8 denotes a truck sill having standards 9 arranged in pairs, near each end, the said pairs of standards constitilting journal bearings for the journals 10 of the wheels 11.
A frame 12 is connected to the sill and a handle 13 is pivoted to a pedestal. secured to the sill 8, as shown in Fig. 4. A post 14 rises from the handle and is provided with shoulders 15 to engage apart or portion of a jacking frame, to be presently described.
Specification of Letters Patent.
Patented Nov. 2, 1920.
Serial No. 337,730.
I The wheels 11 are preferably grooved or flanged so that they may be moved on a rail in transporting the jacking device and the sill has recesses or seats 16 near each end which form anchorages for the lower end of the frame of the jack.
The jack in the present embodiment of the invention comprises two legs or supports 1'? which converge and join each other at their upper ends and the said. supports with the beam 18 connecting them constitute what may be termed a frame for supporting the structures or devices comprising the jackingand transporting elements. a guide 19 is connected to the beam and to the supports 17 near their upper ends and a rack bar 20 is slidable in the said guide, said guide having a slot 21 on one side and a slot 22 on the opposite side to form slideways for the rack bar. Journal bearings 23 and 2% are secured to the supports 17 and a shaft 25 is journaled therein, one end of the said shaft being pro Yided with a head 26 having sockets 27 and 28 therein which receive an operating bar 29 which is used for turning the shaft. A rack wheel 30 is mounted on the shaft and the teeth thereof are engaged by a dog 31, the said, dog being mounted on a pivot 32 carried by the brackets 33. The dog is operative to engage the teeth of the rack wheel to hold the said rack wheel at different positions of adjustment, as the shaft is rotated and as the rack wheel is so mounted as to engage the teeth of the rack bar 20, rotation of the shaft 25 results in communicating motion to the said rack bar so that the same may be elevated or lowered according to the direction of rotation of the shaft and as stated, the dog will hold the rack whee in different positions of adjustment.
The rack bar 20 has an arm 34 supporting a track 85, said track having teeth 36 on its upper face. A carriage 37 is of the general construction shown in the drawing having a slot 38 to receive the track and toothed wheels 39 are mounted in the said groove and ride on the said track, the teeth of the wheel engaging the teeth of the track so that when force is applied to the carriage, it will be caused to move longitudinally of the track for a purpose to be presently explained. The rear side of the carriage has a slot 420 therein through which the arm 34 projects and the carriage is, therefore, free to move on the track as stated. The lower edge of the carriage has a supporting lug 41.
with a spur 42 thereon to penetrate or embed itself into the member applied to it for elevating a car or the like.
As a means for holding the carriage in different positions of adjustment on the track, a detent 48 is slidable in the carriage and is adapted to engage the teeth of the track thus preventing movement of thecarriage with relation to the track so long as the detent is in engagement'with the teeth of the track. fin operating handle 44 is connected to the detent and pivotally connected to a member held by the carriage so that as the said handle is moved upby a connection between it and the carriage through the mai'iipulation of the shaft which will result in elevating the rack bar 20 and that after the car is jacked, the carriage may be moved on its track so that the wheels of the car may be brought into alinement with the rails of a track after which the car may be lowered so that the wheels will rest on the track. 7
The construction and the operation of the elements entering into the combination will, it is thought, he understood from th foregoing description, and a rsum of the operation of the parts is believed unnecessary.
I claim- 1. In a car replacer, a frame, a rack bar guided with respect to the frame, a shaft j ournaled on the frame, a toothed wheel engaging the rack bar, means for holding the toothed wheel in different positions of ad justment, an arm extending from the rack bar, a track supported by the arm, said rack having teeth on its upper edge, a carriage slidably mounted on the said track, toothed wheelsjournaled in the carriage engaging the teeth of the track, and means for holding the carriage in difierent positions of adjustment.
2. In a car replacer, a frame, a rack bar guided with respect to the frame, a shaft j ournaled on the frame, a toothed wheel engaging the rack bar, means for holding the toothed wheel in different positions of ad justment, an arm extending from the rack bar, track supported by the arm, said rack having teeth on its upper edge, a carriage slidably mounted on the said track, toothed. wheels journaled in the oarriageengaging the teeth of the track, and means for holding the carriage in different positions of adjustment, a car supporting member carried by the said carriage, and a clamp engaging the said carriage. g
3. In a car jack, a frame, a truck having a sill for supporting the frame, a handle connected to the sill, and an arm carried by the handle for engaging the frame of the jack for supporting the jack on the frame.
4. In a car j aok, supports having their upper ends converging, a beam connecting the supports and constituting therewith a frame, a guide carried by the said frame, said guide having open sides, a rack bar movable in the guide, a toothed wheel rotatably supported with respect to the frame and having its teeth engaging the teeth of the rack bar, means for holding the, wheel at different positions of adjustment, an arm projecting from the rack bar, a-track carried thereby, a carriage having a slot to receive t 16 arm of the rack bar, and a slot to receive the track, wheels rotatably mounted in the carriage adaptedto travel" on the track, and means constituting apart of the carriage for lifting a car.
