JOHN MORTON, OF CINCINNATI, OHIO.

IMPROVEMENT IN TRACK-LIFTERS.

Specification forming part of Letters Patent No. 122,481, dated January 2, 1872.

I, JOHN MORTON, of Cincinnati, Hamilton county, State of Ohio, have invented certain new and useful Improvements in Track-Lifting Machines for Surfacing and Repairing Railroads, of which the following is a specification:

N atare and Objects of Invention.

My invention relates to improvements upon the machine is adapted to pull anglewise for the purpose of straightening railroad tracks.

Description of Accompanying Drawing.

Figure l is a perspective view of my improved track-lifter. Fig. 2 is a section of a part of the frame, showing the operation of the sliding block and pawl.

General Description.

A is the base of the machine; B, the center-post; and G O, the fulcrum-posts, the latter being framed into the base-plate A. The fulcrum-posts (l C are framed to the centerpost by diagonal braces D D, in the manner shown. The parts A B (J C D D constitute the entire frame of the machine. The centerpost B is slotted, as shown, the lifting-levers E E being fitted to and crossing each other in the slot as shown. A deep groove, b, is also formed in the center-post, the sides of which are notched, as shown. A series of pegs or pins are secured in the center-post near the bottom of the groove b, on which a detachable lever, F, engages in succession to operate the levers E E. Between the lever F and the lifting-levers E E a slide, G, is introduced, which projects through the groove b, and carries a pawl or dog, H, adapted to fit the notches or teeth in the sides of the groove 1).

In the operation of the litter the lever F engages one of the pins a, which forms the ful crum for it, and when it has been forced down to a sufficient distance the lever F is withdrawn and engaged with the next peg below, the pawl H serving to retain the slide G and lifting-levers E E in the position to which they har e been forced until the lever F has been readjusted for the next lift.

For safe keeping the lever F is constructed to fit in between the pins a and the back of the post B, as shown in Fig. 1. The liftinglevers are fitted at the ends with adjustable hooks I I for attachment to the rails to be operated upon, in the manner shown in Fig. 1; and the said levers E E are fulcrumed to the upright posts 0 O, which are introduced to give stiffness and stability to the frame of the machine, and permit of the machine being employed to straighten railroad tracks by lifting an gula-rly-a-n operation for which the track-lifter patented by me March 19, 1867, was not adapted.

For the purpose of enabling the machine to be readily moved along the track from place I to place I attach rollers or pulleys K to the upright fulcrum-posts O O by means of projectin g arms L L and studs or spindles M M. A hook, N, is secured to the top of the post B to afford convenient attachment to a handcar for rapid transportation of the lifter.

My improved lifter is adapted principally for railroad tracks, but can be applied to other uses, such as raisin g buildings or heavy weights.

Claims.

1. In combination with the lift-inglevers E E I I, fulcrumed, as shown, in the frame of the machine, the slide G and pawl H, operated substantially in the manner and for the purpose specified.

2. In combination with the elements of the clause next preceding, the series of pegs or
