CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS,

TRACK LINER.

Application filed June 27,

My invention relates to track lining tools of the general type ilustrated and described in my co-pending application Serial No. 722,799, of even date herewith, the primary object of the present invention being the provision of a modified and, from certain aspects, perhaps preferable mechanical relation between the track shifting member and actuating lever of the tool.

An important object of the invention is the provision of a track liner in which a toggle action may be employed in actuating the track shifting member.

A further object .is the provision of a tool of this character in which the track shifting member is connected with the actuating lever by means of a slotted link adapted to permit slight continued movement of the mem ber after the link has reached its final position. 7

Another object of the invention is the provision. in a combination involving a double pivot between the track shifting member and actuating lever, of means for preventing the parts from moving from starting position until a predetermined stage in the operation is reached.

Numerous other objects and advantages of the invention will be apparent as it is better understood from the following description, which, taken in connection with the accompanying drawings, discloses a preferred embodiment thereof.

Referring to the drawings,

Figure 1 is a side elevation of a track liner in which my invention is embodied, part of the lever and lever socket being broken away for convenience in illustration; and

Fig. 2 is a top plan view thereof.

In the embodiment of the invention shown in the drawings for. purposes of illustration, I have shown a base plate 11, having trans verse bottom ribs 12 adapted to prevent slippage of said plate upon the ground during" operation of the tool, said plate having upstanding ears, or lugs '13 on the upper side near the rear thereof, and a lever socket member 14; being pivoted to said lugs and having secured thereto. in manner to be hereinafter described. a track shifting plate 15, which is adapted to be inserted beneath a rail 16 for the purpose of moving the latter to desired position or relation with an adjacent rail. A lever 17 may be inserted in the socket member 14, though it will be 1924.. Serial No. 722,800.

understood that said member might be eX- L tended in other manner and, for this reason, may itself be referred to as an actuating lever.

The plate 15 is bifurcated at its rear end.

and it will thus be seen that a toggle action is rendered possible by this construction. Lower pro ections 28, on the rear bifurcated portion of the plate 15, have a bolt 24= extendtherethrough and disposed in an openmg 25 in a foot portion 26 of the lever socket 14. The object of this construction is to return the plate 15 to starting position after it has been disengaged from the stop 32, and this is accomplished through a cam action of said belt 241 on the forward walls of said opening.

Said plate 15 is provided-with a plurality of depending flanges 27 and the forward ends of said flanges are beveled, as indicated at 28, to provide a cam surface adapted to act up-onthe upper surface of the base plate 11 between guiding ribs 29 provided at the forward end of said plate. Rearwardly of the beveled portion 28 of the center flange 27, I provide a notch 31 adapted to fit upon a protuberance 82 on the top of the plate to provide a stop preventing forward movement of the plate 15 while the tool is being inserted beneath a. track and until the lever 14: has been lifted a predetermined distance. The foot 26 on said lever socket 14c permits the lifting of the entire mechanism with the base plate 11 without disturbing the relation of the parts. 7

In operation, the tool is positioned under the rail 16 and the actuating lever lifted to first ground the plate 11 and then move the plate 15 in such manner as to shift said track 16 to desired position. The initial part of the lifting movement of said actuating lever serves to firmly ground said plate 11, the plate 15, at this time, being; held against forward movement by means of a stop 32. After said lever has been lifted sufliciently to cause the plate 1 5 to disengage said stop 32, the upward movement ofsaidplate 15 exerts a lateral or forward push upon the rail 16. Provision is made for givi ing an additional forward puslito thei late after it has been raised to this pre etermined position. A shoulder 33 is formed upon the lever socket 14 and is adapted to engage a cam portion 34' on the central flange 27 of the plate 15 when said lever socket is lifted and continued movement of a the socket, after this contact is established,

tends to move the plate1-5 forwardly-across the base 11. The slot 20 in the link 19 allows this action without removing the pressure upon the base 11 which is necessary toprevent slippage thereof, It will be understood, however, that the rail is shifted by the upwardinovement of the plate "15 and that the forward push upon said plate is not essential to successful operation, thou h from certa n stand lnts 1t 1s a Q a v I 7 t distinct feature ofadvantage.

" \Vith the'foregoing construction, accurate positioningof a rail may be accomplished by an ellicient mechanical action involving the use of relatively simple mechanism and inexpensive parts.

- Itis thought that the invention and many of its attendant advantages" will be understood from; the foregoing description, and it will be apparent thatvarious changes may bemade in the form, construction and arrangement of the parts without departing fromt he spiritand scope of the invention,

' or sacrificing all of its material advantages,

the form hereinbefore described being merel a preferredembodiment thereof.-
