tively retaining the tie lifting lever in any desired adjusted position with the tie elevated to the desired degree, whereby manual power or effort in maintaining the tie lifted is rendered unnecessary and the dangers of personal injury to workmen engaged for such purpose, are eliminated.

A further object is to provide a tie lifting jack which may be placed into practical use without the use of additional special tools or special skill, and which may be readily carried about from place to place as required.

Other objects will appear as the nature of the invention is better understood, and the same consists in the novel form, combination 5 and arrangement of parts hereinafter more fully described, shown in the accompanying drawings, and claimed.

In the drawings, wherein like reference characters indicate corresponding parts throughout the several views,

Figure 1 is a top plan view of a tie lifting jack constructed in accordance with the present invention; v

Figure 2 is a side elevational view thereof;

Figure 3 is a fragmentary view of the same substantially in central longitudinal vertical section;

Figure 4 is a horizontal sectional View showing details of the jack; and

Figure 5 is a sectional detail View taken through the adjacent portions of the tielifting lever and the associated keeper bar.

Referring more in detail to the drawings, the present invention embodies a base member or plate 5 which preferably tapers smaller in thickness to its forward end so that the same may be readily forced toward the tie into the ballast for engaging the tie lifting lever under the end of the tie as illustrated in Figure 2, and pivoted upon this base plate 5 is the tie lifting lever 6. The base plate 5 preferably has a pair of spaced longitudinal ears 7 between which the intermediate portion of the lever 6 is pivoted upon a transverse horizontal pivot pin 8 so that the forward tie engaging end of the lever 6 projects slightly beyond the forward end of the base plate 5 for effective engagement under the tie.

In order that the forward lower end of the lever 6 may be more readily forced under the end of the tie, said end of the lever is preferably bifurcated to provide a pair of prongs or arms 9 which taper narrow in thick ness toward their free ends and are disposed to engage under the end of the tie adjacent the sides of the latter. Means is provided for effectively retaining the lifting lever 6 in any desired adjusted position so as to effectively hold the tie elevated to the. point which it has been lifted, and this means preferably includes an upright keeper bar 10 pivoted as at 11 at its lower end to the rear end of the base plate 5 for longitudinal swinging movement, and provided in its rear longitudinal edge with a series of upwardly undercut keeper notches 12 adapted for selective reception of a pin 13, which is adapted for removable selective reception in desired ones of a longitudinal ,series oftransverse apertures 14 provided in the rear .or handle end portion of the lever 6. It is thus apparent that when the forward end of the lever 6 is engaged under the tie and the rear end of the lever is forced downwardly, the tie will be effectively elevated, and when the tie has been elevated to the desired degree, the pin 13 may be inserted in the desired aperture 14 of the lever 6 and caused to engage the nearest notch.

12 upon swinging the keeper bar 10 rearwardly for a slight distance and at the same time releasing the lever 6 so as to allow the pin '13 to ride upwardly into the undercut portion of the slot or notch of the keeper bar '10. In this way the tie is effectively maintained in the desired elevated position with out manual effort and no workman is required to force downwardly upon the rear end of the lever, in which position such workman would 7 be subject to danger of personal injury from glancing hammers and flying spikes which are encountered in track laying, elevating and repairing work.

The lever 6 has a longitudinally extending slot 6 cut therein through which slot the keeper bar 10 passes, this construction eliminating the possibility of the keeper bar slipping away from the lever.

In order to facilitate riding of the pin 13 out of the associated notch when the rear end of the lever 6 is depressed for releasing the tie and allowing it to lower after the desired amount of ballast has been placed thereunder, means is provided for yieldingly acting to swing the keeper bar 10 forwardly, and such means preferably consists of a helical tension spring 15 connected at its rear end to the lower end portion of the keeper bar 10 above its pivot 11 and having its forward end suitably attached to the base plate 5 between the pivots 8 and 11 as shown. The pin 13 is preferably carried on the end of a flexible member 16 attached to the lever 6 so as to prevent 1 its loss, and the upper free end portion of the bar 10 is preferably formed to provide a handle 17 whereby its rearwardly swinging movement against the action of the spring 15 is facilitated when causing the pin 13 to ride into a desired keeper notch 12.

The rear end of the base plate 5 is preferably reduced in width to provide a central bifurcated projection between the arms of which the lower end of the keeper bar 10 is pivoted, and in order to facilitate carrying of the jack from place to place, a rigid bail or handle 18 is preferably provided upon the intermediate portion of the lifting lever 6.

In the preferred embodiment of the invention, the lever 6 is provided in its handle portion with a longitudinal elongated slot upwardly through which the keeper bar 10 freely projects and in which said keeper bar is movable in swinging longitudinally upon its pivot 11. This construction results in effeclieved that the construction and operation as well as the advantages of the present invention will be readily understood and appreciated by those skilled in the art.

What I claim as new is 2-- In a tie lifting jack, a base portion comprising a wedge shaped plate gradually decreasing in thickness toward its forward end having a plain lower bearing face arranged in a horizontal plane, a pair of spaced longitudinally extending pivot ears on said plate, said plate being increased in thickness between the ears, a rearwardly extending bifurcated arm on the rear end of the plate, a lifting lever pivoted between its ends upon the ears about a transverse horizontal axis for vertical swinging movement, the lever including an operating handle in rear of the pivot provided with a longitudinally extending slot, and a keeper bar pivoted in the bifurcated portion of said arm and extendingthrough the slotted portion of the operating handle of the lever, and means for detachably connecting the keeper bar with said handle.

In testimony whereof I aflixmy signature.

OWEN STORMONT.

tively bracing the lever 6 and bar 10 against lateral strain, and the apertures 14 in the lever 6 are provided in pairs for reception of the pin 13.

In operation, the base plate 5 is placed upon the ground adjacent the end of the tie and then the jack is forced toward the end ofthe tie as far as possible so that the forward end of the base plate 5 and the lever 6 are forced into the ballast until the arms 9 engage under the endof the tie. The rear end of the lever 6 is then forced downwardly until the end of the tie has been elevated to the desired degree, whereupon the pin 13 is inserted through the desired pair of apertures 14 in the lever 6 and the proper adjacent notch 12 of' the keeper bar 10, the latter'being forced rearwrardly to proper position for this purpose against the action of the spring 15.
