SPECIFICATION forming part of Letters Patent No. 665,327, dated January 1, 1901. Application filed June 11, 1900. Serial No. 19,981. (No model.)

To (ZZZ whom it may concern:

Be it known that I, PEET JOHNSON, a subject of the King of Denmark, (but having declared my intention to become a citizen of the United States,) residing at St. Paul, in the county of Ramsey and State of Minnesota, have invented certain new and useful Improvements in Track-Jacks; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

My invention relates to improvements in track-jacks; and the object of the invention is to provide a track-jack with means whereby the play often existing between the rail and the tie may be taken up before the tampingof the tie takes place, as otherwise sand is apt to fly in between the rail and the tie and prevent them from coming properly together. This object I attain by the novel construction and arrangement of parts illustrated in the accompanying drawings, in which- Figure 1. is a side elevation of my improved track-jack. a portion of a rail and tie added. Fig. 3 is a modification of the mechanism by which the tie is lifted. Fig. 4 is adetail view of the eccentric P in Figs. 1 and 3 and the stud on which it revolves or rotates. Fig. 5 is a modification of the means by which the eccentric P is turned. Fig. 6 is'a slightly-modified form of the pin G in the other Views.

Referring to the various parts in the drawings by letters of reference, A designates a hollow standard in which slides vertically the lifting-rod B, having the horizontal toe C, adapted to take hold under the rail and elevate it to its proper height preparatory to tamping. The rodB is operated by the handlever F and any suitable intermediate mech- In the present drawings such mechanism consists of the well-known frictionlinks D and D,'of which the latter simply holds the rod B, while the link D, operated by the link E and lever F, descends and takes a new hold of the bar. The bar is let down by holding the links D and D horizontal, so

Fig. 2 is a top view of Fig. 1 with that they do not pinch on the bar B passing through them. The projecting end V of the link D is a hand-hole for so tilting or leveling that link. The other link has a similar end for leveling it with.

The hand-lever F is pivoted on the pin G, which is kept from turning by being square at R in Fig. 4: or by a pin like R. in Fig. 6. The eccentric P is journaled on the projecting end of said pin G, though it may be mounted on a separate stud, and is provided with a handle Q, or a wheel Q in Fig. 5, whereby to turn it.

In the eye studs or lugs I at the side of the standard A slides the rod J, which has a horizontally-swinging vertically-adj ustable toe K,

adapted to take hold under the tie and lift it close up under the rail after the latter is raised to and held in its proper position or elevation. The upper end of the rod J is connected with the eccentric P by the eccentric-rod N and strap 0, which by the adjustmentscrew S is drawn so tight about the eccentric that the latter cannot turn by.the weight of the tie at the toe K, but will hold the tie elevated till the tamping is done.

In the modification in Fig. 3 the chain N takes the place of the eccentric strap and rod.

In the operation the toe O is placed under the rail T (see Fig. 2) and the hand-lever F operated like a pump-handle until the rail is high enough. The toe K is then swung in under the tie, like K in Fig. 2, and the eccentric is turned until the tie comes close up to the rail. Then the tamping takes place.

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

1. A track-jack having a lifting mechanism for raising a rail of a railroad-track, and

a mechanism for raising the tie of the track.

up under the rail when there is a play between the track-rail and the tie.

2. A trackjack having two independent mechanisms, one for raising the rail and the other for raising the tie while the first mechanism is holding up the rail.

3. A track jack having a horizontallyswinging jaw or too adapted to be swung in under the tie when it is elevated with the rail by the main mechanism of the jack, and suitable means for raising said toe, so as to take up any play existing between the track or rail strap holding the eccentric against accidental and the tie. turning, by its frictional contact with it.
