TRACK AND LIFTING JACK.

SPECIFICATION forming part of Letters Patent No, 394,395, dated December 11, 1888.

Application filed March 22, 1888.

To all whom t may concern:

Be it known that I, THOMAS J. REAMY, of Nashville, in the county of Davidson and State of Tennessee, have invented certain new and useful Improvements in Track and Lifting Jacks; and I do hereby declare the following' to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specilication.

My invention relates to an improvement in track and lifting jacks; and the object of my invention is to provide a track raiser or jack which can be placed to one side of the rail, land which makes connection with the rail by means of a lever and grab which catch over one side of the rail only, so as to allow a person to sight along the rail while it is being laid and thus determine whether it is in its proper position or not without the view being interfered with by the jack and the parts which catch hold of the rail.

Figure l is a side elevation of a trackraiser which embodies my invention. Fig. 2 is an edge view of the same. Fig. is a perspective of the chain alone. Fig. 4 shows a modification of the lever which is applied to the rails.

A represents the frame of the jack, in which the rod B is secured. Upon this rod are placed the two ratchet-wheels C, with which the pawls D, placed on the rod E, engage for the purpose of preventing any backward movement. Pivoted upon this rod B are the two arms or levers F, which proj ecta suitable distance beyond the side of the frame, and to the outer ends of which the connectingrods G are pivoted. The outer ends of the two arms F are connected together by a horizontal cross-rod, and upon this rod are placed the two pawls R, which have their upper ends weighted, so as to cause their lower ends to automatically engage with the ratchet-wheels. Vhen the arms are depressed, these pawls engage with the ratchet-wheels C and force them partially around. As soon as the pawls R cease forcing the wheels around, the pawls D engage with them and prevent them from These arms are rigidly moving backward.

Serial No. 268,104. (No model.)

Secured to the shaft B, so that when the arms are operated by the connecting-rods (l and the socket H, which receives the end of the operating-lever I, the shaft B will be operated at the same time. The socket Il is pivoted at its inner ends to suitable ears or bearings, J, which are secured to the jack-frame,

as shown. To the inner sides of the ratchetwheels C, upon the shaft B, are secured suit- 6o able projections, (L, over which the links of the chain pass, and against which the rings N on the outer sides of the ends of the links catch. The links L of the chain consist of i'lat plates or rods, which are pivoted together 65 at their ends, and upon the outside links the rings are formed. These rings catch against the projections upon the inner sides of the ratchet-wheels, so that when the wheels C and shaft I are caused to revolve the chain will 7o be moved at the same time. The lower end of the chain is connected to the lever O, which has its outer end to rest upon the top of the rail which is being operated upon. Pi voted to the side of this lever O near its outer end is a grab, I), which catches under the iiange upon the top of the rail upon one side. When the chain exerts an upward pull, the inner end of the lever (l and the hook shaped part of the grab is made to take a secure hold upon 8o the rail, and the rail can be either lifted bodily or it can be tilted up upon one side, as may be desired. As a lever, O, instead of an ordinary grab is used, a greater leverage is obtained than when a jaw or other device is S 5 used which hangs vertically from l[he end of the chain. This lever projects over the top of the rail, but does not catch hold of it upon either side, and hence does not interfere with sighting along the rail to see whether it is in 9o its proper position or not. This lever also enables the jack to be placed to one side of the rail, and hence the jack does not interfere with sighting along the rails, as is the case where the jack is placed directly over the rail which is being operated upon. The lever and grab may be made in a single piece if so desired, as shown in Fig. 4.

Then the handle I is reciprocated vertically, the arms F cause the wheels to partially 10o revolve and the pawls D prevent them from turning backward. As the wheel C and shaft B are caused to revolve, the projections upon the inner sides of the Wheels catch against the rings N upon the ends of the links of the chain and thus draw the chain upward.

This invention is also designed to be used for all purposes Where a jack is needed for raising houses, vehicles, or heavy objects of any kind. y

Having thus described my invention, I clairnv l'. The combination of a lifting-jack and chainoperated thereby with the lever O,which rests at one end upon the top of the rail, and the grab P, pivoted to the lever, substantially as shown.
