RAILROAD-TIE JACK.

Application filed July 19, 1927. Serial No. 206,984. Y

This invention relatesy to ycertain new and tiey 1, the rack bars 8 being supportedl in the useful improvements in railroad; tie jacks and has for its primary object to provide a jack for placing a tie in position beneath railroad rails'and also for removing a Worn A further obj ect of the invention is to provide a railroad tie-.jack comprising a minimum number of parts capable of quickand easy assembly for the removal and placement of railroad ties beneath rails.

With the above and other objects in view that Will become apparent as the nature of the invention is better understood, the same consists in the novel form, combination and arrangement of parts hereinafter more fully described, shown in the accompanying drawing-s and claimed.

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

Figure l is'a fragmentary top plan view showing a rail tie, a 4rail and the tie jack operatively positioned with respect to the tie and rail;

Figure 2 is a fragmentary side elevational view showing the tie jack in its operative position;

Figure 3 is a cross-sectional view taken on line 3 3 of Figure 2 showing the sup-- por-ts for the side rack bars of the tie jack;

Figure 4 is a detail sectional View taken on line L -l of Figure 1;

Figure 5 is a fragmentary perspective View of one of the side rack bars; and

Figure 6 is a perspective view of the end bar connecting the side rack bars.

Referring more in detail to the accompanying drawings, wherein is illustrated the preferred embodiment of this invention, the reference numeral l designates a `rail tie with a rail 2 supported thereon. The tie jack disclosed in this application is intended for the removal of a Worn out tie and also for placing a new tie in position beneath` in yFigure 5'is positioned at each side ofthe grooved bracket or supporting arms 9 laterthereof and theconnecting end-bar 11 shown in detail in Figure 6 is associated therewith, the end bar 11 being notched at its ends as at 12 to lprovide spaced lugsl that are received in the notches 10 of, the rack bars. When the rack bars and end connecting bar are assembled and associated with the tie as shown in Figures l and 2, the end connecting bar 1l is engaged with the adjacent end of the tie 1 for moving the tie. transversely of the rail upon longitudinal sliding movement of the rack bars.

The shaft 14 is journaled at its ends in the upper ends of the` hangers 3 and the ends of said shafts within and adjacent said hangers carry forked arms 15 in which a pawl 16 is pivotally supported at17, the pawls 16 gravitationally falling upon the upper toothed side of the rack bars 8. The shaft 14 carries a stub handle 18 intermediate its ends and with which a relatively long handle 19 is detachably connected as shown in Figure 2. From the above detailedv description of the device, it is believed that the construction and operation thereof will at once be apparent, it being noted that the frame struct-ure of the jack is positioned in engagement with the rail 2 while the rack bars 8 at each side of the tie 1 are connected at one end by the end connecting bar 11 which is rpositioned for engagement with the adjacent end of the tie l. -By moving the handle 19 to the left from the position shown in Figure 2, the pa wl 16 ratchets overI the rack bars 8 and when the handle 19 is moved in the opposite direction, the reverse rotation of the shaft 14 imparts movement to the pawls 16 and sliding movement of the rack bars 8, the end connecting bar 11 that is engaged with the end of the tie moving the tie from beneath the rail 2. The tie is removed in a step by step movement and in a similar manner a new tie is placed into position. In removing an old tie, the jack is placed in engagement with the outer side of the outer rail and the jack is placed in engagement with the inner side of the inner rail when a new tie is being placed into position.

While there is herein shown and described the preferred embodiment of the present invention, it is nevertheless to he understood that minor changes may be made therein Without departing from the spirit and scope of the invention as claimed.

What I claim as new is n e l. In a railroad tie jack, a pair of rack I bars, and an end connecting bar plaCed in frame engaged with a rail, a yshaft journalled in the frame, paWls carried by the shaft engaged With the rack bars7 and a handle on the Shaft to effect oscillation thereof to cause the paWls-to move the rack bars in a stepbystep movement, the frame including a pair of hangers and supporting arms on the .hangersfor the rack bars.

3. In a railroad tie jack, a pair of racky bars, and an end connecting har placed in inclosing relations with respect to a tie, a rail engaglng frame, `a shaft Journalled 1n the frame, forked arms extending from the shaft, pawls carried by the ,forked arms .en-

gaged With the rack bars and operating means for .the shaft, the frame including a pair of hangers and supporting arms A.on the hangers for the rack bars Y l In testimony whereof I aifix my signature.
