GAR-LIFTING DEVICE.

Application. filed April 23, 1925. Serial No. 25,201.

To all whom 2 2, may concern:

Be it known that I, ALLAN O. CARPENTER, a citizen of the United States, and a resident of Corning, county of Steuben, State of New York, have invented a certain Car-Lift ng Device, of which the following is a specification accompanied by drawings.

This invention relates tolifting devices for cars, such as railway cars, adapted to run 011 a track, in order that the car may be shifted from the track on transverse lifting wheels running on transverse rails. I

The objects of the invention are to enable the car to be readily and quickly lifted and shifted on transverse wheels by simple de- "vices which are at the same time cheap and rugged in construction.

Another object of the invention is to permit the car to be carried directly upon the transverse wheel yokes or supports when shifted, so that'the weight of the car is not borne by the'transverse wheels while at rest on the transverse rails.

The invention is shown in one of its preferred forms in the accompanying drawings, in which a Figure l'is a diagrammatic side elevation of the lifting device applied to a portable compressor car adapted to run ona railway track and intended to be used for furnishing compressed air for the operation of tie tamper tools;

Figure 2 is an enlarged detail top plan view partly in transverse section of the lifting device on the line 2-2 of Figure l;

Flgure 3 is an end elevation partly broken away of the car shown in Figure 1 illustrating the lifting devices with the lifting wheels locatedupon a transverse rail in the act of lifting the tie tamper car;

Figure 4 is a view similar to Figure 3 showing the tie tamper car shifted transversely from the main track and resting on the lifting wheels;

Figure 5 is an enlarged detail vertical sectional viewof one of the lifting devices on the line 55 of Figure 2 looking in the direction of the arrows and illustrating the device in the same position indicated in Figure t with the lifting device locked;

Figure 6 is a view similar to Figure 5 showing the manner in which the weight of the railway car is permitted to rest directly upon the lifting wheel yokes which are lodevice comprises a similar view showing the the compressor E furnishing compressed air to the storage tank or reservoir F. The weight of the car and of the operating machinery carried thereby is considerable, so that the lifting devices must be capable of withstanding the strain necessarily imposed in lifting the car upon transverse wheels G and shifting it along the transverse rails H.

The tie tamper car is preferably provided with four lifting devices, one on each corner is illustrated in the drawings and these lifting devices are preferably in the form of attachments which may be secured to the car frame A in "any suitable or convenient manner. As shown in the drawings, each lifting yoke bracket J having an attaching member K and a forked supporting member L. The attaching member K of the yoke bracket is adapted to be secured to the car frame A as by means of bolts 0 and P and extends downwardly from the frame. In the fork L of this yoke bracket is pivoted a wheel yoke Q having a forked portion R and a lifting member S, which lifting member is preferably in the form of a socket adapted to receive the end of an ordinary lining bar T which is always avail able when tie tan'ipering operations are in progress, although any suitable bar or lever will suffice for rocking the wheel yokes on their pivot pins U. The lifting wheel G is pivoted to the forked portion of the wheel yoke by means of the pin V.

A suitable locking device in the form of a latch W is provided for locking the lifting device with the lifting wheel G in raised position as indicated in Figures 1 and 7 when the railway car is travelling on the main track rail C. This latch is also adapted to lock the lifting wheel G in located position as indicated in Figures 3 and 5 TO INGERSOLL-RAND COM- wheels located in raised position The car is when the railway car is being shifted transversely along the transverse rails H; The latch IV is slidable vertically in the groove or guideway X formed in the attaching member of theyoke bracket and is provided with a slot Y through which one of the bolts P passes to limit the movement of the latch. The lower end Z of the latch cooperates with the stop aformed on the wheel yoke for locking the wheel yoke and lifting wheel in located posit-ion as indicated in Figure 5, and also cooperates with the web I) on the wheel yoke forming a stop in order to lock the wheel yoke and lifting wheel in raised position as indicated in Figures 1 and 7. The latch may be raised and lowered by means of the hooked portion a in order to permit the running of the wheel yoke on its pivot, andv when the yoke is in the desired position the latch is dropped to lock the parts.

In Figure 6, the tie tamper car has been rolled upon the transverse rails and then while the car is to remainat rest, the wheel yokes have been rocked to raise the lifting wheels and the bearing portions (Z and the wheel yokes have been permitted to lie directly upon the transverse rails II so that the lifting wheels G are out of contact with said rails and the entire weight of the tie tamper is carried by the wheel yokes directly upon the transverse rails. The latch WV has been lowered and thus locks the parts in position.

I claim:

I. In a railway car, the combination with the car frame and trackwheels, of transverse yoke brackets attached to the car frame, transverse wheel yokes pivoted to said yoke brackets, lifting wheels carried by said wheel yokes, means for rocking said transverse wheel yokes', and means for locking said wheel yokes either in raised or lowered posit-ion of the Wheels.

2. In a railway car, the combination with the car frame and track wheels, of transverse yoke brackets attached to the car frame, transverse wheel yokes pivoted to said yoke brackets, and having bar sockets and lower bearing members adapted to bear upon transverse rails, and lifting wheels carried by said wheel yokes, whereby the railway car may be wheeled transversely from the track along transverse rails and then lowered and supported at rest directly on the wheel yokes.

3. In a railway car, the combination with the car frame and track wheels, of transverse yoke brackets attached to the car frame, transverse wheel yokes pivoted to said yoke brackets, and having bar sockets and lower bearing members adapted to bear upon transverse rails, and lifting Wheels carried by said wheel yokes, whereby the railway car may be wheeled transversely from the track along transverse rails and then lowered and supported at rest directly on the wheel yokes, and means for locking said wheel yokes either in raised or lowered position of the wheels.

i. In a railway car, a car lifting device comprising a yoke bracket having an attaching member and a forked supporting member, a wheel yoke pivoted to the said supporting member and having a forked portion and a lifting member, a lifting wheel carried by said forked portion, and a latch adjustable on the attaching member of the yoke bracket for locking the wheel yoke in raised or lowered position of the wheels.

In testimony whereof I have signed this specification.

ALLAN O. CARPENTER.
