DEVICE FOR LINING RAILROAD TRACKS.

Application filed September 7, 1922. Serial No. 586,721.

1 0 aZZ 20720777, it may concern.

Be it known that I, JOHN F. ELLIOTT, a citizen of the United States, residing at Al le-rton, in the county of l Vayne and State of Iowa, have invented certain new and useful Improvements in Devices for Lining Railroad Tracks, of which the following is a specification.

The present invention relates to a track liner or jack and the main object of this invention is to provide a device of this character, which requires a minimum amount of labor for handling, so that the railroad track can be properly lined with dispatch avoiding the use of a great number of implements, which are ordinarily employed for this purpose.

lhe device is very strongly built without unnecessary weight and may be handled with ease and transported from place to place without difiiculty.

These track lining jacks are used in pairs one under each rail opposite to each other and the device is placed under the rail in such a manner, that when the rocking handle is pulled down, the so-called crowding bar will be raised and as it engages under the foot of the rail, the latter will be slightly lifted and pushed over to one side. For this purpose the crowding bar has an inclined surface, the slope of which will gradually increase as the bar is raised compelling the rail to slide down the incline and in this manner be pushed away from the jack.

In the accompanying drawing one embodi ment of the invention has been illustrated and Fig. 1 is a vertical section of the device, and

Fig. 2 is a top plan view thereof, partly in section.

Reference numeral 10 represents a base consisting of a flat board or plate 11 preferably made of cast-iron and having sharp claw-like ledges 12, one at each end of the base. At one end of the base are provided a pair of bearings 13 in which the crowding bar 14 is fulcrumed upon a journal 9 and the other end of the base has a pair of cheeks .15, in which a shaft 16 is mounted to revolve and upon which the operating lever 17 is mounted.

This lever is preferably provided with a socket 18 for receiving a handle 19 andha-s a segment 20 at its lower end furnished with teeth 21 engaging with corresponding teeth 22 in the free end of the crowding bar 14.

As shown in the drawing the ratio bet-ween the lengths of the radii for the gear teeth 21 and 22 is substantially as one to four, so that with a good length of the handle 19, a considerable leverage will be obtained onthe crowding bar 14:; Furthermore the upper face of the crowding bar is curved as at 23, slanting downwardly from the upper-most tooth 22 towards the fulcrumed end of the 1 bar for the purpose of wedging the bar under the foot of the rail 24. In swinging the handle 19 of the lever 17 in the direction of arrow X in Fig. 1 the crowding bar 14 will be raised thus forcing the foot of the rail upwardly and inwardly until the correct position has been found.

It will be noted that the device is very substantially built and only consists of five solid parts, which cannot readily be broken or get out of order and any of which parts, however, may be quickly replaced by others in the case. of injury.

Having thus described the invention, what is claimed as new is:

1. A track lining jack comprising a base, ground-engaging members on said base, a crowding bar fulcrumed on the base, a rocking lever similarly fulcrumed on the base, and interengaging means between said lever and said bar for oscillating the latter, said crowding bar having an arcuate cam surface adapted to engage with the rails.

2. A track lining jack comprising a base, ground-engaging sharp edged ledges on said base, a crowding bar fulcrumed on the base, a rocking lever similarly fulcrumed on the base, and interengaging means between said lever and said bar for oscillating the latter, said crowding bar having an arcuate cam surface adapted to engage with the rails, and said interengaging means including toothed segments integral with said rocking lever and said crowding bar respectively.

3. A track lining jack comprising a base, ground-engaging sharp edged ledges on the under side of said base, bearing members on said base, a crowding bar between said bearing members, a journal carried in said members and in which the crowding bar is fulcrumed, a pair of cheeks on the other end of said base, a shaft mounted in said cheeks, a rocking lever fulorumed on said shaft, a toothed segment integral With said rocking lever, a oorrespondingly-toothed segment integral with said crowding bar and meshing with said first toothed segment, and said crowding bar having an arouate cam surface 10 adapted to engage under the foot of a rail. In testimony whereof I afiiX my signature.
