TRACK-ADJUSTING JACK.

Specification of Letters Patent.

Patented Aug. 23, 1910.

To all whom it may concern:

Be it known that we, BENJAMIN F. HACKE'I'I and JOHN J. OWEN, citizens of the United States, residing at Willard, in the county of Torrance and Territory of New Mexico, have invented certain new and useful Improvements in Track-Adjusting Jacks; and we 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.

This invention relates to improvements in trackalining and lifting jacks.

The object of the invention is to provide a jack of this character by means of which track rails may be brought into proper alinement or gage and by means of which the rails may be lifted to'the proper. grade or level.

With the foregoing and other objects in view, the invention consists of certain novel features of construction, combination and arrangement of parts, as will be more fully described and particularly pointed out in the appended claims.

In the accompanying drawings, Figure 1 is a longitudinal sectional view of a jack constructed in accordance with the invention; showing the same engaged with a track rail for the purpose of alining the same; Fig. 2 is a top plan view of the same; Fig. 3 is a side view, showing the manner of using the jack for lifting a rail; Flg. 4 is a detail perspective view of the detachablleI evening block for the foot piece of the ac Referring more particularly to the drawings, 1 denotes the body portion of the jack in which is formed a guide channel 2 to receive the adjustable operating bar 3. On one end of the body portion 1 is formed an obliquely disposed wedge shaped foot piece 4, one end of which has formed thereon an anvil 5 whereby the opposite end may be driven into the ground to form a stop or abutment against which pressure is applied when the jack is operated. The foot piece 4 is provided on one side with a rail engaging plate 6, the purpose of which will hereinafter appear.

On the inner end of the adjustable operating bar 3 is formed a stop ug 7 while on the outer end of the same is secured a rail engaging head 8 which is preferably rounded on its outer end, as shown, to fit between the base flange and head of the rail when applied thereto. Onthe outer side of the operating bar 3 is formed a series of ratchet teeth 9 which are adapted to be engaged by operating pawls 10 and 11 pivotally mounted in the bifurcated head 12 of an operating lever 13, said lever being preferably detach'ably engaged with the head 12 by means of a socket 14 formed on the head, as shown. The head 12 is pivotally mounted in aper tured ears 15 formed on each edge of the open side of the body ortion 1 whereby the pawls 10 and 11 earned by the head will work in the channel 2 and operatively engage the ratchet teeth 9 of the operating bar to project the same outwardly. The pawl 11 has formed on its outer end an inwardly projecting hook 16 which engages the teeth 9 of the bar 3 so that when the operating lever and head are swung in one direction, the hook on the pawl 11 will engage the teeth 9 and when the lever and head are swung in the opposite direction, the pawl 10 will operatively engage the teeth 9 so that the operating bar 3 is projected forwardly at each movement of the lever.

In using the device for alining a track rail, the head 8 is engaged with the rail and the foot piece driven into the ground thus forming a brace, after which the operating lever is actuated to engage the pawls with the operating bar, thus projecting the same, as hereinbefore described, and forcing the rail into alinement.

When the jack is employed for lifting a rail, an evening piece 17 is provided and engaged with the anvil end 5 of the foot piece so that when the jack is stood up in position to engage the plate 6, with the underside of the rail to be raised, the piece 17 will support the outer end of the foot piece in proper osition and will act as a fulcrum on which e jack may be rocked in the operation of lifting the track. If desired, the pawls 10 and 11 may be provided with suitable handles 18 for disengaging the same from the teeth of the operating bar. The body portion of the jack may be also pro vided with a handle 19 by means of which the same may be more readily carried.

It will be noticed that as the foot piece 4 is secured on the body 1 obliquely, that the jack will not assume a vertical position when the anvil end of the foot so that when the head 8 is placed under an object to be lifted the rack bar 3 will stand vertically and the .is employed as in Fig. 3', (as a fulcrum piece), and when it is placed under some object to be lifted.

' From the foregoing description, taken in 7 connection with the accompanymg drawings, the construction and operation of the invention will be readily understood with-4 out requiring a more extended explanation.

Various changes in the form, proportion and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of the invention, as defined in the appended claims.

Having thus described our invention, what we claim is:

1. In a jack of the character described, a body portion having formed therein a guide in said channel, a head on the outer end of said bar, means 'to project the latter, an

oblique foot piece on one end of saidbody portion adapted to be driven into the ground to form ananchoring brace, a rail enga plate on said foot iece, and an evem iig dalock adapted to be etachably engaged with said foot piece to hold the jack in an upri ht position. v

2. In a ifting jack, a body, an operating bar slidably mounted therein, means for projecting the same from one end of the body, an ob ique bracing foot on the op osite end of the body and an evener block etachably engaged with the foot to hold the jack in upright position.

Intestimony whereof we have hereunto set our hands in presence of two subscribing wltnesses. I
