LlFTlNG-uJACKn Specification of Letters Patent.

Patented Oct. 24, 1905.

Application filed March 1, 1905. Serial No. 247,936-

To (0Z6 whom it may concern:

Be it known that we, PRESTON R. PARKS and SIMON E. MoDoUeAL, citizens of the United States, residing at Mammoth, in the county of Kanawha and State of West Virginia, have invented a new and useful Lifting-Jack, of which the following is a specification.

This invention relates to lifting-acks, more particularly'to implements of this character employed in railway construction and repairs, and has for its object to simplify and improve the construction and increase the efiiciency and provide an implement Whereby the tie members may be firmly supported in position while the holding-spikes are inserted and driven home.

With these and other objects in view, which will appear as the nature of the invention is better understood, the same consists in certain novel features of construction as hereinafter fully described and claimed.

In the accompanying drawings, forming a part of this specification, and in which correspending parts are denoted by like designating characters, is illustrated the preferred form of embodiment of the invention capable of carrying the same into practical operation, it being understood that the invention is not necessarily limited thereto, as various changes in the shape, proportions, and general assemblage of the parts may be resorted to without departing from the principle of the invention or sacrificing any of its advantages.

In the drawings thus employed, Figure 1 is a perspective view of the improved device applied, Fig. 2 is an enlarged detailed perspective view of a portion of the apparatus. Fig. 3 is a View, on a reduced scale, illustrating the manner of coupling to the railwayrail. Fig. 4 is a perspective view of the supporting-block for the improved jack.

The device herein shown and described is designed for holding railway-ties in position and bearing firmly beneath the rails while the holding-spikes are being inserted, and comprises a standard 10, having a lateral hook 11 at one end for bearing beneath the head or tread. portion of a railway-rail (represented at 12) and with a plurality of spaced transverse recesses 13 in one edge and ratchetteeth 14 in the other edge and with the upper end formed into a handle 15.

Mounted to swing upon the lower end of the standard 10, as by a relatively loose bolt 16, is a curved plate 17, having at the lower end a lateral hook 18 for bearing against the opposite side of the rail 12 and with acam member 19, mounted for operation in its upper end, as by an operating-lever 20, and bearing against the body of the standard 10. The plate 17 being curved and the holdingbolt 16 relatively loose, the plate will rock upon the adjacent face of the standard, so that when in open position, with the cam member relapsed, the hooked end 18 will be spaced sufficiently from the hooked end 11 of the standard to enable the hooked ends to be placed over the head of the rail when the standard is tilted sidewise, as shown in Fig. 3, and then when the standard is brought to a vertical position and the cam member applied the plate 17 will be firmly clamped to the rail and hold the standard firmly in position, as illustrated in Fig. 1.

, An operating-lever 21 forms a part of the structure and is provided with a laterally-extending pin 22 for engaging the recesses 13, the pin having an enlarged head 23 to assist in holding the lever in position. The shorter end of the lever 21 is formed with a flattened terminal 24, in which a depending hook is swiveled at 26, the free end of the hook being relatively close to the terminal 24, except at one point, where the under face of the portion 24 is cut away, as at 27. Engaging the hook 25 is a link 28, the link insertible into the hook only when the terminal of the latter is opposite the cut-away portion 27, as represented in Fig. 2.

Mounted to swing, as by links 29 30, from the link 28 are clamp members 31 32, pivoted intermediately, as at 33, and having pointed hooked ends 34 35 for engaging the opposite sides of the tie, (represented at 36.)

Pivoted at 39 to the lever 21 is a pawl 40 for engaging the ratchet-teeth 14.

By this simple arrangement the standard 10 can be uickly coupled to a railway-rail at any desirdd point and firmly clamped thereon adjacent to the tie which it is desired to elevate and the tie grasped by the gripping members 31 32 and thelever 21 positioned upon the standard and the longer end depressed, with the e'lfect of causing the points 34 35 to be firmly compressed into the opposite sides of the tie and elevating the same firmly beneath the rail in position to receive the holding-spikes. WVhen the spiking operation is completed, the gripping members 31 32 and the cam member 19 are released and the device moved along the rail and arranged for operation upon the next tie, and so on as long as required.

It will be obvious that it will not be necessary to remove the standard member entirely from the rail in moving from tie to tie, but to simply loosen the cam members 19, except where frogs and switches occur, and when found necessary to remove the device bodily it can be done very quickly and as quickly reattached in the new location.

If it is required to lift the tie bodily or both ends at once, a section of railway-rail, as at 37 in Fig. 4, will be attached to a base-block 38, the standard 10 to be coupled to the rail-section, and the base-block to be placed between the rails adjacent to the center of the tie, and the members 31 32 applied, as above described. The tie will thus be bodily elevated, and if one end rises first the lifting force will be continued until both ends are in the required position bearing beneath the rails.

The block 38 and its rail-section 37 may also be employed at the ends of the ties outside the rails 12, if required.

The device can be adapted for all sizes and forms of railway-rails and for rails employed in any locality.

The device will be found especially valuable for use in mining and similar operations.

Having thus described the invention, what is claimed is 1. In a device of the class described, a standard, means connected to said standard for clamping over and beneath the head portion of a railway-rail, a lever swinging from said standard, and a clamping member swinging from the shorter end of said lever and having means for coupling to a railwaytie.

2. In a device of the class described, a standard having means for detachably connecting to a railway-rail and provided with spaced transverse recesses in one edge and a plurality of ratchet-teeth in the other edge, a lever having a lateral pin for adjustably engaging said recesses, a pawl swinging from said lever for adjustable engagement with said ratchet-teeth, and a clamping member swinging from the shorter end of said lever and having means for coupling to a railwaytie.

3. In a device of the class described, a standard having a lateral hook at one end for engaging beneath the tread of a railwayrail at one side, a clamp-lever mounted to swing intermediately from said standard and having a lateral hook at one end for engaging beneath the opposite side of the head portion of a railway-rail and with a cam member at the other end for bearing against the standard, a lever swinging from said standard, and a clamping member swinging from the shorter end of said lever and having means for coupling to a railway-tie.

4. In a device of the class described, a standard having a plurality of spaced transverse recesses in one edge and spaced ratchetteeth in the other edge and with a lateral hook at the lower end for bearing beneath the head portion of a railway-rail at one side, a clamp-lever mounted to swing intermediately from said standard with one end provided with a lateral hook for bearing beneath the opposite side of the head portion of the railway-rail and with a cam member at the other end for bearing against the standard, a lever having a lateral pin for adjustable engagement with said recesses, a pawl swinging from said lever for adjustable engagement with said ratchet-teeth, and a clamping member swinging from the shorter end of said lever and having means for coupling to a railway-tie.

5. In a device of the class described, a standard having means for detachably coupling to a railway-rail, a lever swinging from said standard and with a laterally-extending portion at the terminal of the shorter arm having a section cut away at an incline on one side, a hook swiveled in said laterallyextending portion with its free end disposed relatively close to the body of the same and spaced from said cut-away section, a link for engaging said hook and insertible therein and removable therefrom only when the terminal of said hook is disposed opposite said cut-away portion, and pivoted clamp members coupled to said link for engagement with a railway-tie.

In testimony that we claim the foregoing as our own we have hereto afiiXed our signatures in the presence of two witnesses.
