LAWRENCE P. PUGKETT, OF MIDVILLE, GEORGIA.

TIE-SPACING JACK.

Application filed January 4 To all whom it may concern:

Be it known that I, LAWRENCE P. Poonnrr, a citizen of the United States, residing at Midville, in the county of Burke and State of Georgia, have invented new and useful Improvements in Tie-Spacing Jacks, of which the following is a specification.

This invention relates to tie spacing jacks for the purpose of shifting railroad ties into proper position when they have become displaced by traffic; and it has for its object to provide an implement of simple and eilicientconstruction whereby ailroad ties may be subjected to a heavy pressure for the purpose of bringing them into proper position with reference to the rails.

A further object of the invention is to construct an. implementcomprising a jack of ordinary construction in connection with attachments of an extremely simple nature, whereby it may be converted to the purposes outlined above.

Still further objects of the invention are to produce simple and efficient devices which may be readily applied to and used in connection with an ordinary lifting jack for the purpose set forth.

IVith these and other ends in view which will readily appear as the nature of the invention is better understood, the same consists in the improved construction and novel arrangement and combination of parts which will be hereinafter fully described and particularly pointed out in the claim.

In the accompanying drawing has been illustrated a simple and preferred form of the invention, it being, however, understood that no limitation is necessarily made to the precise structural details therein exhibited, but that changes, alterations and modifications within the scope of the invention may be resorted to when desired.

In the drawing,Figure 1 is a view in side elevation illustrating a portion of a railroad track and showing the improved syncing jack or implement in connection tierewith. Fig. 2 is a top plan view of the same. Fig. 3 is a perspective detail view, showing the head of the extension stem of the jack in connection with the rail-engag ing plates applied thereto. Fig. a is a transverse sectional view talren on the plane indicated by the line 4& in Fig. 2. Fig. 5 is a perspective View, showing the rail-gripping plate detached.

Specification of Letters Patent.

Serial no. 536,253.

Corresponding parts in the several figures are denoted by like characters of reference.

A lifting jack A of any suitable conventional construction may be used in connection with this invention; (3 designating the base or frame, 7, the extension stem or rack and 8, the lifting lever of such jack; the base being provided with the foot piece 9, and the extension stem or rack being equipped with the head 10.

By preference, a jack is employed having a stem or rack which is square or rectangular in cross section to facilitate the adjustment adjacent to the head of two plates 11 and 12 of steel or other suitable material, said plates being provided with apertures for the passage of clamping bolts 13, whereby they may be securely mounted adjacent to the head 10. These plates are of unequal dimensions, the top plate 11, which is mounted adjacent to the side of the stem facing the lifting lever 8, being somewhat longer so as to be capable of overlapping the head 17f of a railroad rail, while the bottom plate 12 stops short of the rail web 15 when the device is in position for operation.

A rail gripping plate 13 of heavy steel or other suitable material is provided, said plate being provided with a notch 16 where by it may be adjusted upon the head of a rail in such manner as to bite upon and grip the rail head very securely when the projecting end 17 of the plate is subjected to pressure.

In operation, the gripping-plate B is adjusted upon the rail to form a bearing or abutment for the head of the tick, the foot of which is braced against the tie that is to be displaced, the adjustment being such that the rail-engaging plates 11 and 12 will engage the rail head, as clearly seen in Fig. d of the drawings, after which by manipulating the lever 8, pressure will be exerted against the tie which will thus be gradually moved into the desired position, it being obvious that the ballast adjacent to the tie has been previously removed to a sutlicient extent to enable the tie to be moved. It may sometimes be found necessary to draw the spikes from the tie before shifting its position, but frequently this is not necessary. The notch 16 of the gripping-plate B is made of such dimensions that it will just loosely fit over the head of the rail so that pressure upon the projecting end 17 of the plate will cause it to exercise a strong gripping action, whereby displacement is made practically impossible; the jack is held against tilting While in operation by the rail-engaging plates 11 and 12. The jack or implement may be readily shifted from one place to another, and it is obvious that the plate B may be readily moved to any desired position upon the rail.

It Will be seen from the foregoing description that the gripping-plate B and the railengaging plates 11 and 12, together with the bolt or fastening members for the latter, constitute a very simple device which may be readily attached to and used in connection with an ordinary lifting jack for the purpose set forth, and a lifting jack thus equipped may be very efficiently used in the manner described and With excellent results.

Having thus described the invention, What is claimed as new, is

A lifting jack having an extension stem, and rail-engaging plates of unequal length mounted upon said extension stem adjacent to the head thereof, in combination with a notched rail-engaging gripping plate affording an abutment for the jack.

In testimony whereof I afiix my signature in presence of tWo Witnesses.
