Specification of Letters Patent. Application filed August 11, 1905. Serial No. 273.735.

Patented July 17, 1906.

To all whom it may concern:

Be it known that I, PEMBERTON DUDLEY, a citizen of the United States, and a resident of .Asbury Park, in the county of Monmouth and State of.New Jersey, have invented a new and Improved Trolley-Role, of which the following is a full, clear, and exact descri tion.

T e purpose of the invention is to provide a ball-and-socket connection between the laterally-curved guide and fork, which construction is 'si economic,

and effective and allows the trolley-wheel to accurately follow the wire even when the wire is not exactly overhead and alsoto follow the wire upon all manner of curves, said construction also insuring the wheel bein straight'upon the wire regardless of the angle of the pole.-

The invention consists in the novel consuplport for the mp e I struction and combination of the several parts, as will be hereinafter fully set forth,

and pointed out in the claims. v M

' Reference is to be had to the accompanying drawings, formin a part of this specification, in which simi ar characters of'reference indicate corresponding parts in all the figures. p

Figure 1 is a front elevation of the upper end of a trolley-pole, the fork-holder, and, fork, showing the latter in two positions. Fig. 2 is a vertical section taken substantially on the line 2 2 of Fig. 1; am. Fig. 3 is a sectional plan view, of the device, the section 11% g taken substantially on the line 3 3 of i'represents the trolley-pole, and B the support connected with the trolley-pole and adapted as'a g'uide, as well as a support,for the fork-G, The support Bis hollow and in general contour ,is similarin outline to the outline of an inverted triangle, the side ed es extending outward and upward in opposite directions from its contracted end, and the upper and wider end is open and is rendered more or less convex, whi contracted end of the aid combined guide duced, as. is shown in Fig. 2. The combined guide and support B is made "as light gas ipossible {consistent iwith fork for the trolley wheel and the pole and a In order that-the fork centrally located with respect to the holder,

e at the lower and and support B a circu ar socket 10 is prostrengthand is constructed in two sections 11 and 12, the dividing line being centrally and longitudinally located. The section 11 is integral with the pole A; but the section 12 has a hinged connection 14 with the pole, as is shown held together by forming lugs 13 and 13" at the central portions of the side faces A of the said sections and passing bolts 14 through said lugs.

In addition to the eculiar fan or angular formation of the com ined holder and guide B the said holder or guide is laterally curved, its one face 15 being concaved and the opposing face 16 convex, as is shown best in Fig. 3. The socket 10 is partially in one section and partially in the other section of the holder. Thetrolley-Wheel 17 is mounted to turn in the usual manner in the fork O, and the said forkC is provided with a-downwardly-extending stern 18, substantially rectangular in. cross section. The said stem asses loosely down through the said holder be ing ada ted for-tree lateral movement in the said he der, ball 19, mounted loosely "in ,the aforesaid socket 10. It will be understood that any approved means provided.

as is shown by full lines in Fig. 1, springs 28 bear against oppositecurved sides o the shank or stem 18 of the fork, which springs are located within the holder B and aresecured to the side walls of the said holder near its lower end by bolts 21 or their equivalents.

When a trolley-pole has the above-de scribed improvements applied,v the trolleywheelis bound to follow the wire even when the wire is not exactly overhead and will,

positively follow the wire under all manner of curves. thirty degrees to the car the curvature in the fork-holder will permit the wheel to still keep straight on the wire and not ca'nt'in direction of the pole. i I

Having thus described my invention, I claim as new and desire tosecure by Letters Patent in Fig. 1, and the two sections are as the-said stem terminates in ao se n be was,

for oilingthe ball may be Even if the pole is at an angle'of 1. A trolley-pole, a trolley-fork having a tending from the ,bztll-rrndsocket connection with and a holder in Winch-the fork has guide-d movement, said holder being lotemll'y curved 35A trolley-pole, a substantially trihngw lorly-slmped hollow holder having its contracted end connectodwith the pole, being open at the top and provnml f-t circular socket at its bottom portion, one side the said holder being concoved and the other convezied, e trolley-Wheel fork, o slnml': e2:-

t'ork into the said holder, having lateral movement therein, and o ball at the lower end of the shim fitted in the socket at the bottom of sold holder.

4. A trollc '--pole, e s1ibstontinl y triangulorly-slmped hollow holder having contracted end connects-1i with the sole, being open at the top and providei'l, with o cirouler socket at its bottom portion, one side fsce of said holder being concoved and the other convexed, o trolley-Wheel, fork, a shank extending from the fork into the said holder, having loterol moven'ient therein, and :1 ball at the lower end of the shank, fitted in the socket at the bottom of the said holder, springs located Within the said holder, heirw ed. above its c of I l l a 4 i l l formed at the lower or corn esoid holder, the said holder being constructed in tWo sections, one sec tion integral with the pole and the other section neving l'iinged connection With said pole, one side face of the said holder being concirvod and the other face convexed, and means for securing the sections of the holder together, of o trolley-Wheel fork, a shank extending from the said fork into the said holder, ball at the lower end of the said shank, which is'iitted in the said socket in the holder, and springs located Within the holder, secured at their bottomends, their upper ends being free and in en 'agement sh opposite sides of the shank 0 thesaid trolley xnheel "fork.

in testimony whereof I have signed rny.
