UNITED STATES PATENT EEICE,

LEOPOLD FRITZ, OF MILWAUKEE, IVISOONSIN.

CAR-JACK.

SPECIFICATION forming part of Letters Patent No. 582,468, dated May 1 1, 1897.

Application filed March 10, 1897.

To all whom it may concern:

Be it known that I, LEOPOLD FRITZ, a citizen of the United States, and a resident of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Oar-Jacks; and I do hereby declare that the following is a full, clear, and exact descriptionthereof.

My invention relates especially to devices for replacing railway-cars upon their tracks when they have accidentally left the same; and it consists in certain peculiarities of construction and combination of parts, as will be fully set forth hereinafter and subsequently claimed.

In the drawings, Figure 1 is avertical central sectional View of my device, showing its mode of operation. Fig. 2 is a partly-sectional plan view, and Fig. 3 is a transverse vertical sectional view of a portion thereof.

Referring to the drawings, A represents the movable platform of my device, whichis intended to be placed adjacent to the end of the car to be moved. This platform consists, preferably, of a solid center a, (which may be of wood,) framed with cross-beams b b, secured together by bolts 0 c and cross-ties (Z (Z, and there being preferably additional crossties e 6 between the projecting ends of the cross-beams, whereby the platform may be drawn or moved about to the desired points by the hook B. The upper face of the solid center a is,provided with recesses f f for the reception of series of antifriction-rollers g g. It is obvious that the platform may be cast or otherwise formed in whole or in part of metal, but the construction described is the preferable one.

C is a horizontal revolving disk formed, preferably, of wood, but, if of wood, with a metallic base h, and having, preferably, a metallic band or periphery 1 D is a standard rising from the center of said disk, the upper part of said standard being divided, as shown at j 7'.

E is a pivot pin extending downward through a vertical opening in the lower part of the standard D and projecting into a socket 7;; in the center of the platform A, said pin E having aneye in its head through which a bolt m passes, whereby the said pin E is rigidly secured to the standard D.

Serial No. 626,768. (No model.)

If the standard D is made of wood, the outer sides of its upper portionsjj are preferably reinforced'by metallic facing-plates not, as shown, and said partsj j are provided with registering series of holes 0 0. Straps or stayrods 19 p are provided, running from the disk 0 to the said standard, to brace and strengthen the latter.

F is the operative lever of my device, and is made, preferably, of metal with a socketed shank to receiveawooden handle-bar G. This lever is provided with a series of holes q q, and said lever is slipped down between the parts jj of the standard D and adj nstably secured therein by a pin H, passing through one of said holes q and opposed holes 0 0 in the standard.

I is a clip to prevent the divided parts jj of the standard from spreading in use when under strain, the upper ends of said partsjj being notched or recessed for the reception of the horizontal part of said clip, and the latter being preferably attached to the'standard in any suitable way, as by hinge-bolt r, to prevent its loss in transportation. The standard D is further preferably strengthened by a band-clip t, as shown.

The forward end of the lever F has swiveled thereto a bearing-plate J, (with washers, if desired, on its pivot-pin, as shown,) the upper surface of said plate being preferably grooved or roughened to increase its hold.

K is a chain secured to the lever F back of the standard D, and L is a hook on the disk 0 for engagement with any of the links of said chain when it' is desired to prevent the forward end of the lever from being forced downward in use by the weight upon it.

The forward end of the lever F is preferably formed with a downward curve or bend, as shown at u, just back of the bearingplate, to provide space for any downward projections on the end of the car.

The operation of my device will be readily understood from the foregoing description of its construction, taken in connection with the accompanying drawings, Suppose that a street-car, for example, is oif. the track. My device is brought to a point near the end of the car to be operated upon, the hook B-being used to secure the exact position required. The lever is introduced under the car with the bearingplate J just beneath the rear end of the ear M and the handle-bar of, the lever depressed. Then by turning the said lever to one side or the other the car can be readily moved until its wheels are just over the tracks. If it becomes necessary to get beneath the car afterit has been raised the lever is made stationary by means of the described chain K and hook L, and thus all danger is obviated. \Vith my device the replacement of a car upon its track is usually a matter of only a few minutes, whereas without such a device frequently a very long time is required.

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

1. In a car-jack, the combination of a platform or base, a rotary disk pivotally secured thereon, a standard rising from said disk, and a lever ad j ustably secured to said standard, and having a bearing-plate at its forward end, substantially as and for the purpose set forth.

2. In a car-jack, the combination of a platform or base, provided With series of antifriction-rollers on its upper surface, a rotary disk pivotally secured to said base and resting 011 said rollers, a divided standard rigidly secured to and rising from said base and provided with series of adjusting-holes, a lever also provided with a series of ad] usting-holes,

supported between the divided portions of the standard, a fulcrum-pin for adj ustably securing said lever in position, and a bearing-plate swiveled on the forward end of saidlever, substantially as set forth.

3. I11 a car-jack, the combination of a platform or base, provided with series of antifrietion-rollers on its upper surface, a rotary disk pivotally secured to said base and resting on said rollers, a divided standard rigidly secured to and rising from said base, and provided with series of adjustingdioles, a lever also provided with a series of adjusting-holes supported between thedivided portions of the standard, a fulcrum -pin for ad justably securing said lever in position, a bearing-plate swiveled on the forward end of said lever, a chain depending from the lever back of the standard, and a hook for engagement with any of the links of said chain, substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand, at Milwaukee, in the county of Milwaukee and State of \Viscousin, in the presence of two witnesses.

LEOPOLD FRITZ.
