r oLLEY SLEET CUTTER.

Application filed March 16, 1922. Serial No. -'544,217.

T 0- all whom it may concern:

Be it known that I, CHARLEs T. Panama citizen of the United States, residing at Staten Island, in the county of Richmond and State of New York, have invented new and useful Improvements in Trolley Sleet Cutters, of which the following is a specification.

This invention relates to improvements in trolley sleet cutters and has for its principal object to provide a device for cutting and removing sleet from trolley wires and other exposed conductors which are used for carrying electric currents and the like.

Another object of the invention is to provide a device which is particularly adapted for use on the so-called trackless trolleys.

A further object of the invention resides in the provision of a shoe formed of a suitable conducting material which is adapted to be removably fitted on the trolley head in such a manner that regardless of the position of the trolley wires across the face of the shoe, it will act to cut and break the sleet or other foreign substance from the wires so as to permit a good contact to be made.

A still further object of the invention is to provide a device which may be readily at tached or detached from a trolley head so as to enable it to be removed during the summer season and replaced when desired.

With these and other objects in view the invention consists in the novel construction, combination and arrangement of parts which will be fully set forth in the following specification and claims and illustrated in the accompanying drawing, in which,

F igure 1 is a top plan view of a trolley head showing this improved sleet cutter in place thereon.

Figure 2 is a front view of Figure 1.

Figure 3 is a side view of Figure 1.

Figure 4 is a front view of a modified form of the device, and

Figure 5 is an enlarged fragmentary sectional view through the sleet cutter, illustrating the construction in detail.

Referring to the drawing, the numeral 10 desi ates in its entirety, the upper end of a trol ey pole which comprises the arms 11 which are connected by the trolley head 12.

This'head comprises a pair of conducting members which are divided centrally by an insulating block 13, and connected at their outer ends to suitable-supporting members 14, secured to the arms 11. Formed at the outer ends of the conducting'members are shields 15 which form guides for retaininghe trolley wires in proper relationto the The preferred form of sleet cutter consists of a plate or shoe 16 which is made arcuate in cross section to fit the curvature of the conducting members. Formed on the outer or convex side of the plate 16 are rectangular studs 17 arranged in longitudinal and transverse alignment to provide grooves in which the trolley wire 18 fits. It will be understood that the studs 17 are placed sufficiently close together to prevent the trolley wire 18 from engaging the surface of the plate 16 as shown in Figure 5, thereby insuring the cutting and loosening of any accumulation of foreign matter upon the wire.

In the modified form of the invention illustrated in Figure 4:, the sleet cutter is designated generally by the numeral 19 and comprises an arcuate shoe 20 which is adapted to fit the head 12. This shoe as shown is shorter than the width of the trolley head and is provided with the shields or 'guards 21 at opposite ends which.insure the proper position of the shoe with relation to the trolley wire. Obviously the shortening of the shoe will enable the same to be adjusted to various positions longitudinallyon the trolley head. Formed on the outer convex side of the shoe are the studs 22 which like the studs 17 arearranged in spaced parallel rows to provide grooves to receive the trolley wire. Obviously this type of device will efi'ect a considerable saving over the modification shown in Fig. l, for when the shoe becomes worn it may be readily replaced and the quantity of metal used, equals approximately only one-third of that used in the production of the device such as illustrated in Figure 1.

While in the foregoing, there has been shown and described the preferred embodiment of this invention, it is to be'understood that certain minor changes, in the details of construction, combination and arcombination with a trolley having a pair of conducting shoes arranged in longitudinal alignment and insulated from each other, of,

a pair of sleet cutters adapted to fit over the shoes and out foreign matter from the trolley Wires. I

2. A trolley sleet cutter comprising, the combination with a trolley having a Contact shoe, of a studded plate adapted to fit over the face of the shoe to remove foreign matter from atrolley wire.

3. A trolley 'sleet cutter comprising, the combination with a trolley, and a curved 20 contact shoe on the trolley of an arcuate plate adapted to fit the convex face of the shoe, and spaced parallel rows of studs on the convex face of the plate for engaging a trolley Wire and removing foreign matter therefrom.

gaging a trolley Wire and removing foreign matter therefrom.

5. A trolley sleet cutter comprising, an arcuate plate adapted to fit over the contact shoe of a trolley, and spaced parallel rows of rectangular studs on the convex face of the plate to provide grooves for receiving a trolley Wire.

Signed at N. Y. city, in the county of New York and State of New York, this 3d day of March, 1922.

C. T. PERRY.
