THEOPHILE EUPHRAT, OF NORWALK, CONNECTICUT.
ELECTRIC TROLLEY-WHEELQ SPECIFICATION forming part of Letters Patent No. 788,526, dated May 2, 1905.
Application filed August 25, 1904. Serial No. 222,052.
To all 1071,0111, it may concern:
Be it known that 1, THEOPHILE EUPHRAT, a citizen of the United States of America, and a resident of Norwalk, county of Fair-field, and State of Connecticut, have invented certain new and useful Improvements in Electric Trolley-Vheels, of which the following is a specification.
My invention consists of a combined plain trolley-wheel for ordinary use and an ice-detaching attachment which is inoperative in the ordinary use of the wheel and is readily adjustable into operative ice-detaching condition at any time when sleet and ice are collecting on the conducting-wire, as hereinafter described, reference being made to the accompanying drawings, in Wl1lCl1-- Figure l is a side elevation of my improved trolley-wheel in the form at present preferred. Fig. 2 is an elevation as seen looking in a direction at right angles to the view of Fig. 1. Fig. 3 is a vertical section on line 3 3 of Fig. 2. Fig. 4: is a transverse section on line 4 4 of Fig. 1, with the ice-cutting attachment in its inoperative position. Fig. 5 is a detail in the same section as Fig. 4, showing the icecutting attachment in operative position. Fig. 6 is a perspective view of one member of a pair of cam-rings used in shifting the ice-cutting devices from one position to another. Fig. '7 is a perspective view of an ice-cuttercarrying disk forming part of the ice-detaching attachment. Fig. 8 is a side elevation of a wheel slightly modified in some of its details. Fig. 9 is a transverse section on line 9 9 of Fig. 8. Fig. 10 is an inside elevation of one of the adjustable ice-cutter-carrying disks. Fig. 11 is a perspective view of a nut that may be used for shifting the disks by screwing on the hub of the wheel. Fig. 12 is a detail showing a face View of one of the camrings employed for shifting the cutter-carrying disks.
A represents a grooved trolley-wheel of ordinary construction, which according to my invention is made with numerous radial slots (1. through the sides parallel with the axis and communicating with the groove 6, which runs on the wire, and it is provided in the said preferred form with preferably two curved slots 0 through the web parallel with the axis and on a radius of said aXis and being oppositely located relatively to said axis. There may be three or more of these slots, if desired.
B, Figs. 1, L, 5, and separately shown in Fig. 7, represents cutter-carrying-disks, one to each side of the wheel armed with radial cutters d, adapted to the slots at for being made to project into the groove bfor ice cutters or breakers, as shown in Fig. 5, or for lodging flush with the inner surfaces of the groove, according as the carrying-disks B are shifted in or out laterally and set in one position or the other.
The disks B are centered on a couple of camrings 6, respectively, so as to shift slightly on them, said rings being fitted on the hub f of the'wheel, so as to turn thereon to a limited extent, and being respectively placed on the opposite end portions of the hub and coupled together through slots 0 by pins 9, fixedly connecting the two rings, so that they turn together when either one is turned by the fingers of the operator applied to finger-pieces h.
The disks B have two outside cam projections 2' placed opposite each other radially, and the cam-rings have correspondingly-arranged cam-surfaces j for coacting therewith to force the disk inward when the rings are turned one way, said cam-surfaces being in this instance formed on the insides of the finger-pieces h, and said disks have two inside cam projections 70, with which corresponding inside cam projections Z of the cam-rings act to force the disk outward. The inside cam projections Z of the cam-rings enter within the inside cam projections 71; of the disks at the notches m. The two rings are then connected together by pins 9, inserted through the heels of cam projections Z and through the slots 0 of the web of the wheel A, said pins being riveted and permanently headed. The cam-rings 6 being put in position after the disks B are applied escape of the disks is prevented by the bearing of cam-surfacesjagainst cams i, retraction of cam-surfacesjsufliciently to permit escape of cams a being prevented by the pins 9 coming against the end walls of slots 0. Instead of these cam-rings grooved nuts screwing on the hub of the wheel A, as
at p, Figs. 8 and 9, maybe employed for shifting and controlling the disks, the inner edges q of the disks being engaged in the grooves r of the nuts, said edges being notched at s and the inner part a of the nut being notched at o for entering said part of the nut to the inside of the disk for engaging said part a in the groove, whereby the disk may be shifted forward and backward by turning the nut one way or the other, said entering being effected by the projections of one part passing through the notches of the other part.
What I claim as my invention is- 1. The combination in atrolley-wheel, of a normal grooved wheel having lateral perforations of the sides of the grooved part communicating with the groove, laterally-adjustable cutter-carrying disks, one on each side of said wheel, with cutters entering said perforations, and means for setting said cutters inward for operative effect on the trolley-wire and for. retiring them for non-action thereon.
2-. The combination in a trolley-wheel, of a normal grooved wheel having lateral perforations of the sides of the grooved part communicating with the groove, laterally-adjustable cutter-carrying disks, one on each side of said wheel with cutters entering said perforations, and rotatory means carried on the hub of the wheel for setting said cutters inward for operative effect on the trolley-wire and for retiring them for non-action thereon.
3. The combination in a trolley-wheel, of a normal grooved wheel having lateral perforations of the sides of the grooved part communicating with the groove, laterally-adjustable disks, one on each side of said wheel and carrying laterally-projecting cutters coinciding with the said perforations, and cams for setting said cutters inward for operative eflect on the trolley-wire and for retiring them for non-action thereon.
4. The combination in atrolley-wheel, of a normal grooved wheel having lateral perforations of the sides of the grooved part comm unicating with the groove, laterally-adjustable disks, one on each side of the wheel and carrying laterally-projecting cutters coinciding with the said perforations, and rotatory cams carried on the hub of the wheel for setting said cutters inward for operative effect on the trolley-wire, and for retiring them for nonaction thereon.
5. The combination in a trolley-wheel, of a normal grooved wheel having lateral perforations of the sides of the grooved part communicating with the groove, laterally-adjustable l disks, one on each side of the wheel and carrying laterally-projecting cutters coinciding with the said perforations, rotatory cam-rings carried on the hub of the wheel and coact ing with the disks respectively, and cam projections of the disks coacting with the camrings.
6. The combination in a trolley-wheel, of a normal grooved wheel having lateral perforations of the sides of the grooved part communicating with the groove, laterally-adjustable disks, one on each side of the wheel and carrying laterally-projecting cutters coinciding with the said perforations, rotatory cam-rings carried on the hub of the wheel and coacting with the disks respectively, said rings connected together through the web of the wheel, and cam projections on the disks coacting with the cam-rings.
7. The combination in a trolley-wheel, of a normal grooved wheel having lateral perforations of the sides of the grooved part communicating with the groove, laterally-adjustable disks, one on each side of the wheel and carrying laterally-projecting cutters coinciding with the said perforations, rotatory cam-disks carried on the hub of the wheel, and coacting with the disks respectively, said rings connected together through the web of the wheel, with pins which are stopped against ends of the slots in the web of the wheel to prevent escape of the disks, said disks notched for passing the cam-lugs of the rings in assembling the several parts.
8. The combination in atrolley-wheel, of a normal grooved wheel having lateral perforations of the sides of the grooved part comm unicating with the groove, laterally-adjustable cutter-carrying disks, one on each side of said wheel with cutters entering said perforations, said disks each having two systems of cam projections for thrusting it in opposite directions respectively, and two rotatable canirings respectively having two systems of cams cooperating with the disk-cams for adjusting said disks in opposite directions.
