JAMES TEMPLE, OF SELINS GROVE, PENNSYLVANIA, ASSIGNOR TO HIMSELF AND H. P. HOTTENSTEIN.

IMPROVED MODE OF RAISING RAILROAD-TRACKS.

Specification forming part of Letters Patent No. 51,523, dated December 12, 1865.

To all whom fit may conce/rn.-

Be it known that I, JAMES TEMPLE, of the town of Selins Grove, in the county of Snyder, in the State of Pennsylvania, have invented al new and Improved Machine for Raising Railroad-Tracks; and I do hereby declare that the following is afull and exact description thereof, reference being had tothe accompanying drawings, and to the letters of reference marked thereon.

The nature of my invention consists in providing a simple and powerful mechanical device for raisin g railroad-tracks, whereby a large saving of labor and cost is obtained.

From various reasons, not necessary to mention, (well known to most persons,) railroadtracks will settle at different points,the opposite rails not being on a level, thus giving rise to a rollin g or rocking motion ofthe cars, and sometimes leading to accidents. This necessitates the laying off of roads into sections, generally oftive miles each, f1ve men being assigned to each section to keep watch, repair, Src., and the raising is generally done with crow-bars by hand and thepropping up or underpinning with the same and other hand-tools. This operation is slow, laborious, and expensive.

To enable others skilled in the art to make and use my invention, I will proceed todescribe its construction and operation.

Figure 1 represents an elevation of my machine. Parts connected therewith are represented in adjacent drawings, designated by same letters of reference.

In the drawings, A A represent the feet of the machine, B B the legs sufficiently separated to straddle a tie or rail or the whole track, if desired. In the center of the top circular or arched part, C, I secure the mechanical device to accomplishthe desired result. This mechanism consists of a vibrating rack-bar, D, a pinion-bar, E, which slides in the former, one or more wheels, F, to gear in the pinion-bar, these latter being attached to arbors G, which carry a ratchet-wheel, H. These arbors work in curved slots, so as to accommodate the pinionwheels each may carry to the rackbar. If both feet, A, are not on a level the rack-har will not be perpendicular; neither the pinion-bar which moves through it.

This is a self-adjusting device. The vibrating bar D is not pivoted-that is, it does not vibrate on an axle passing through it, but vibrates on its circular part J, which `works in corresponding parts ofthe top frame, forming a circularjoint, permitting a limitedvibratory motion. Turning the crank or cranks I raises or lowers the hooks K, which are secured to E by a. swivel, e, affording them a motion of rotation. To raise the track in order to underpin, Src., all that is necessary is to first lower the hooks and grasp any desired part, turn the crank in the opposite direction and raise the same, underpin, Src., and move to another point.

A machine weighing fifteen pounds is capable ofraising some eight hundred pounds, while one weighing thirty-tive pounds will raise three tons. lt must be easily seen what labor can be saved thereby. On each live-mile section, into which railroads are generally divided, some live men are employed to repair, and as watchmen. Using my machine two can be dispensed with on each section. That is a saving of eighteen thousand dollars on each and everyr one hundred miles. v

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-

l. The combination of the vibrating rackbar D with the rack or pinion bar E, constructed and operating `substantially as described, for the purpose set forth.

2. The combination of said parts D and E with pinion -wheels F and frame C B, operating conjointly to produce the result above mentioned.
