ELECTRIC RAILWAY.

Specification of Letters Patent.

?atented May 15, 1906.

Application filed May 28,1905. Serial No. 261.883.

To aZZ whom, it may concern:

Be it known that I, JOHN A. GAREY, a citizen of the United States, residing at T arkio, in the county of Atchison and State of Missouri, have invented a new and useful Electric Railway, of which the following is a specification.

This invention relates to electric-railway systems, and particularly to systems wherein a third rail is arranged on the surface of the ground or slightly below the surface.

One object of the invention is to provide a novel form of plow that will be freely supported and maintained in proper position to insure good contact between the traveling current-collector and the third rail.

A further object of the invention is to provide a novel form of current-collector which may be readily shifted from one side of the plow or carrying-frame to the other in accordance with the direction in which the car is traveling.

With these and other objects in view, as will more fully hereinafter appear, the invention consists in certain novel features of construction and arrangement of parts, hereinafter fully described, illustrated in the accompanying drawings, and particularly pointed out in the appended claims, it being under stood that various changes in the form, proportions, size, and minor details of the structure may be made without departing from the spirit or sacrificing any of the advantages of the invention.

In the accompanying drawings, Figure 1 is a longitudinal sectional view of sufficient of an electric-railway system to illustrate the invention. Fig. 2 is a transverse sectional view of the same, illustrating, on an enlarged scale, the construction of the third rail and its supports and the position of the plow with respect thereto.

Similar numerals of reference are employed to illustrate corresponding parts throughout both the figures of the drawings.

In carrying out the invention two sills or beams 10 and 11 are arranged at a short distance apart and are supported at suitable intervals by cross-ties 12. The sill 11 is of less vertical height than the sill 10 and serves as a support for the third rail 18, the contact face of which is grooved for the reception of a current-collecting wheel 19 in the form of a double cone that is supported in the manner hereinafter described. On top of the sill 11 is placed an auxiliary sill member 20, the lower inner face of which is recessed forthe reception of the third rail, the latter being insulated from the sills and being held in place by the bolts 22, which clamp the sill members to the cross ties. This method of construction is cheap and durable, it being merely necessary to place the sill member in position and then the third rail 18, after which the upper sill member is clamped in place. The third rail is held from lateral displacement by making its inner edge somewhat wider than its outer or contact edge and shaping the recess of the upper sill in a corresponding manner. The two sill members are preferably sheathed with iron and at their upper inner corners form rails for the support of two pairs of wheels 24.

The wheels 24 are provided with axles 25, having suitable bearings in the plow-frame 26, said frame being formed of bars of iron or steel rigidly secured together and carrying a lower plate or shoe 27 and an inclined plate 28, that inclines downward toward the front end, where it is connected to the plate 27, and thus forms a plow which extends below the level of the third rail and will remove any 0bstruction in the form of dirt, snow, or the like which may accumulate between the sills.

The plow-frame is supported by a slot-bar 30, suitably guided in a frame 31, that may form a part of the car, and to the upper end of the slot-bar is secured an adjusting-lever 33, that may be locked in place by a notched segment 34 and bolt 35 of the usual type. To prevent damage to the plow, the opposite sides of the frame are provided with bearings for the support of rollers 37, which engage against the inner faces of the sills should there be any vibration of the plow; but it is not in tended that these rollers should remain constantly in contact with the sill members. Accidental contact between the rollers and the third rail is prevented by placing the latter so that its contact-face will be somewhat within the line of the vertical wall of the sill.

The slot-bar is provided with bearings for the reception of a vertical spindle 39, to the lower end of which is secured a pair of rockerarms 40, that are insulated from the spindle, and these arms are rovided at their outer ends with bearings far the reception of the traveling contact-roller 19. The upper end of the spindle is provided with a lever 41, which may be moved over a notched lockingsegment 42 and locked in position thereon by the usual latch-lever 43, so that the currentcollecting roller may be shifted from one side to the other when the car is turned around, and it will be unnecessary to employ a third rail at each side of the conduit.

In order to insure the removal of the dust and dirt, means are employed for directing a blast of air in advance of the plow. In the present instance a blast-fan 45 is employed, the device being mounted under the truck or frame of the car and provided with a drivingpulley 46, which may be driven by a belt or the like from one of the axles, or a separate electric motor may be provided for the purpose. From the fan-casing leads a blast-fan 47, having an outlet in alinement with the inclined plate 28 of the plow, so that the current of air will be directed downward and in advance of the plow and will eject the dirt loosened by the plow and at the same time will clean the third rail, and thus insure good electrical contact between the rail and the current-collecting wheel or rail.

Having thus described the invention, what is claimed is- 1. In apparatus of the class described, the

combination with a pair of sills, of a third rail supported by one of the sills, a plow dis: posed between the sills, a vertical spindle journaled in the plow, rocker-arms extending from the spindle, a current-collecting wheel carried by the arms and engaging the third rail, and means at the upper end of the spindle for rocking the same to permit adjustment of the current-collector from side to side of the space between the sills.

2. In apparatus of the class described, the combination with a pair of sills, of a plow arranged between the sills, supporting-wheels carried by the plow and running on the sills, and guard-rollers carried by the plow and arranged to engage the adjacent vertical faces of the sills.

3. In apparatus of the class described, the combination with a pair of spaced sills, of a third rail supported by one of the sills, a plow, a current-collector carried thereby and engaging the third rail, supporting-wheels carried by the plow and running on the sills, and antifriction-rollers supported by the plow and adapted to engage the adjacent vertical faces of the sills.

4. In apparatus of the class described, the combination with a pair of spaced sills having metal sheathing on their inner and upper faces, a third rail supported by one of the sills, a plow, wheels carried by the plow and running on the upper inner edges of the sills, guard-rollers carried by the plow and arranged to engage the adjacent vertical walls of the sill, and a current-collector supported by the plow.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
