is o. 870,043.

Specification of Letters Patent.

Patented Nov. 5, 1907.

Application filed June 27. 1907. stun No. 380,994.

To all whom it may concern:

Be it known that I, ANDREW J. MAINE, a citizen of the United States, residing at Appleton, county of Outaganiie, and State of Wisconsin, have invented new and useful Improvements in Car-Movers, of which the following is a specification.

My invention relates to improvements in car movers.

The object of my invention is to provide a tool of this class which will automatically and without loss of power grip the rail when the power is applied to the actuating lever, and thus prevent the tool from slipping backwardly on the rail.

A further object of my invention is to provide better construction and arrangement of the actuating levers than those heretofore used, to secure a balanced tool and balanced pressure at all pivotal points with a maximum strength for a given weight. Also to locate the pivot bearing of the load lever above the point of initial pressure on the wheel, whereby the load end of the lever is made to swing forwardly and upwardly instead of up wardly and backwardly as in the devices in common use.

In the following description reference is had to the accompanying drawings in which,

Figure l. is a side view of my invention as it is applied to a car wheel. Fig. 2 is a rear elevation of the rail gripping members. Fig. 3isa side view with part of the shoe and one arm of the actuating lever fork broken away to show the load lever. Fig. 4 is a plan view. Fig. 5 is a vertical section drawn on line :t'."c of Fig. 3.

Like parts are identified by the same reference characters throughout the several views.

A shoe 1 is adapted to slide along the rail. Near its front end it is provided with downwardly projecting ears 2 which straddle the head of the rail, and near its rear end, it is provided with pivotal gripping dogs 3 adapted to grip the head of the rail at the sides or partially be neath it. The pivot bolts 4, for these dogs, extend longitudinally of the shoe. The shoe is provided with a longitudinal channel 6 in which a load lever 7 is mounted, this lever being connected with the shoe by a pivot bolt 8 and having concave bearing members 9, resting upon convex marginal bearing surfaces 10 of the shoe above the pivot bolt 8, whereby the lever is permitted to oscillate in the shoe channel on this pivot bolt as an axis, the strain, however, being upon said bearing surfaces.

An actuating lever 11 is provided with forked arms 12 which straddle the rear end portion of the load lever and are pivotally connected therewith at 13 near the crotch of the fork. The fork arms form an open elbow with the lever 11, and their extremities are connected by links 14 with inwardly projecting arms 15 of the gripping dogs above the pivot bolts 4, whereby an upward pull exerted by the fork arms on the links, causes the jaws of the gripping (logs to move inwardly below their pivotal connection with the shoe and thus grip the rail. Set

screws 18 may also be employed for increasing the friction on the rail, thesescrews having threaded engagement with the shoe and having pointed or knife edged ends 19 which bite into the rail when the levers are in use. The edges or points of these screws may be sharpened from time to time and the screws adjusted so that the rail engaging ends will project slightly and engage the rail. These set screws may, however, be omitted if desired.

The specific form or arrangement of the levers, as shown and described, is not material to my invention, since various modifications will be suggested to the mind of the ordinary mechanic familiar with this dis closure.

In use, the shoe is adjusted to the rail and moved toward the car wheel, with the rear end of the actuating lever in a raised position until the depressed point of the load lever engages with the wheel. The rear end of the actuating lever is then depressed, whereupon the links 14 are lifted as this lever tends to rock upon its pivotal connection 13 with the load lever, thus actuating the gripping jaws. The links 14 then serve as fulcrums for the actuating lever which is employed to depress the rear end of the load lever, and cause it to move against the periphery of the wheel which is thus forced to roll along the track. The raised

pivot bearings

8 and 9 being located above the point of the load lever, it is obvious that the latter will swing forwardly as well as upwardly, and impart a maximum degree of movement to the wheel.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is,

1. A car mover comprising a support, a lever fulerumed thereto, and adapted to engage a car wheel, an actuating lever, rail gripping devices mounted on said support and connected therewith, and connections between the rail gripping devices and the actuating lever, arranged to communicate a gripping movement to the said devices during the working stroke of said lever.

2. A car mover comprising a support, a lever fulcrumed thereto, and adapted to engage a car wheel, an actuating lever, rail gripping devices mounted on said support and connected therewith, and connections between the rail gripping devices and the actuating lever, arranged to communicate a gripping movement to the said devices during the working stroke of said lever, said connections be ing also arranged to serve as a fulcrum for the actuating lever during its working stroke.

3. A car mover comprising a support, a lever fulcrumed thereto, and adapted to engage a car wheel, an actuating lever, rail gripping devices mounted on said support and connected therewith, and connections between the rail gripping devices and the actuating lever, arranged to communicate a gripping movement to said devices during the working stroke of said lever, said connections comprising links pivotal ly connected with actuating levers on 0pposite sides of the first mentioned lever.

4. A car mover comprising a rail shoe, a set of gripping devices connected therewith, an actuating lever operatively connected with the gripping devices and a load lever ful crumed to the rail shoe and pivotally connected with the actuating lever between its outer end and the point of connection with the gripping devices.

5. A car mover comprising a rail shoe, a set of gripping devices connected therewith, an actuating lever operatively connected with the gripping devices and a load lever fulcrumed to the rail shoe and pivotally connected with the actuating lever between its outer end and the point of connection with the gripping devices, said actuating lever being forked and arranged to receive the connected arm of the load lever between the fork arms.

(1. A car mover comprising a rail shoe, a lever pivotally connected therewith, and adapted to engage a car Wheel, an actuating lever, rail gripping devices mounted on said shoe and connected therewith, and connections between the rail gripping devices and the actuating lever arranged to communicate a gripping movement to said devices during the working stroke of said lever, said first mentioned lever having supporting fulcrum members in rocker hearing contact with said shoe above the pivotal axis and above the point of initial lever contact with the wheel.

l l l l 7. A car mover comprising a rail shoe, :1 set of gripping devices connected therewith, an actuating lever operatively connected with the gripping devices and a load lever fulcrumed to the rail shoe and pivotally connected with the actuating lever between its outer end and the point of connection with the gripping devices, said rail shoe being also provided with set screws having rail gripping projections.

S. A car mover comprising a rail shoe provided with a longitudinal channel in its upper surface, a load lever pivotally secured to the shoe and oscillating in said channel, said load lever having projections above the pivot and the shoe having curved bearing surfaces for said projections, a forked actuating lever connected with the shoe, and straddling the rear end of the load lever and a pivotal connection between the rear end of the load lever and the actuating lever.

In testimony whereof I affix my signature in the presence of two witnesses.
