FREDERICK HACKMANN, OF'CI-IICAGO, ILLINOIS,

TRACK-ALIGNING JACK.

Application filed January 25, 192%. Serial No. 688,395.

To all whom it may concern:

Be it known that I, Fnnomuon HACK- MANN, a citizen of the United States, and a resident of the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in a Track-Aligning Jack; and I hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the numerals of reference marked thereon, which form a part of this specification.

This invention relates to a rail aligning jack which is adapted for engaging the lower flange of the rail for shifting the same laterally.

The invention comprises the novel struc ture and combinations hereinafter described and more particularly pointed out and defined in the appended claims. I

In the accompanying drawings which illustrate a preferred embodiment of this invention and in which similar reference numerals refer to similar features in the different views Figure 1 is a sectional view through a railroad track illustrating a pair of my improved rail ali ning jacks, in elevation and in operation.

Figure 2 is an enlarged section through the jack taken substantially upon the line.

2-2 of Figure 1, showing parts in elevation.

Figure 3 is an enlarged fragmentary ver tical sectional view with parts in elevation.

Figure 4: is an elevational View of a modified form of the rail engaging element.

Referring to the drawings which illustrate one embodiment of this invention, the reference numeral 1 indicates the base of the jack from which a hollow standard or guide rises. The guide is shown as of hollow rectangular form having an opening 3 (Fig. 2) in its front face. A rack bar l is slidably mounted in the guide 2. The upper end of the rack bar is provided with ratchet teeth 5 adapted for engagement'by a pawl (not shown) upon an operating lever 6 pivoted upon thestandard. The operation of such a rack bar by a lever is well known and needs not be specifically illustrated.

The lower end of the rack bar is provided with a forwardly extending lug 7 upon which the rail engaging device is removably are illustrated. The preferred form consists of a shoe or supporting member 8 having a downwardly inclined outer end or face 9 and a .mortise or socket in its inner end which fits the lug 7 as shown in Figure 3. A rail engaging element lOis pivoted upon the upper outer corner of the shoe 8. The

upper side of this element is serrated forv of rail engaging device. The same consists of a rail engaging element having a horizontal portion 11 provided with a socket for engaging over the lug '7, and a downwardly inclined outer portion 12 which extends below the horizontal portion, and

engaging the rail. Y

In use, the jack is positioned adjacent the rail to be shifted or aligned, with the rail engaging element under the rail, as shown in Figure 1. Then by operating the handle 6, the rack bar may be elevated whereby the lateral component of force directed against the rail by the inclined face of the rail engaging element will shift the rail laterally as is apparent.

It will be appreciatedthat the jack is simple in construction and eflicient in operation, the removable feature of the rail engaging element allows another of greater or less throw to be substituted or a new element substituted if the old one wears out.

I am aware that many changes may be made, and numerous details of construction may be varied through a wide range without departing from the principles of this invention, and I therefore do not purpose limiting the patent granted hereon, otherwise than necessitated by the prior art.

I claim as my invention:

1. In a rail aligning ack, a base, a hollow vertical guide having its front side partially open rising from said base, a rack bar slidably mounted in said guide and having a which is serrated upon its upper surface for.

. supported, Several rail engaging devices lug projecting through the open side thereof, a support having a downwardly sloping end removably secured upon said lug, a rail engaging element pivoted to said support and means for operating said rack bar.

2. In a rail aligning jack, a base, a hollow Vertical guide rising from said base,-a rack bar slidably mounted in said guide and havsupporting member removably secured upon ing a horizontal lug upon its lower end, a

said supporting member, and means for operating said rack bar.

I 3. In a rail aligning ack, a base, a hollow Vertical guide rising from said base, a rack 5 In testimony whereof I have hereunto sub 20 scribed my name.
