7'0 all whom it may concern:

Be it known that l, ("n/mans C. MCCL1N- TOOK, a citizen'of the. United States, residing at lGngleWoo'd, in the county of Arapahoc and State (if-Colorado, have invented certain new and useful .lmprovements in 'lrolley-lleads,

of which the following is a specification, reference being bad to the accompanying drawings.

My invention relates to improvements in The above and other olnects which will ap- Specification of Letters Patent. Application filed June 25. 1907. swarm. 380.703.

and have their lower ends secured u pear as the nature of the invention is better understood are attained in the preferred cmbodimcnt of my invention illustrated in the accompanying drawings in which Figure 1 is a side elevation of the Fig. 2 1s a vertlcal section; Figs. 3 and 4 are Formed in the top and bottom of t sections taken respectively on planes indicated by the lines 3, 3 and 4, 4 in Fig. 2; Fig. 5 is a detailed view of the guard or deflector, and Fig. 6 represents side and sectional views through the locking washer.

In the drawings 1 denotes the usual trolley wheel suitably journaled upon a bolt or shaft 2 arranged transversely in the arms 3 of a fork or yoke 4. The latter has a comparativelybroad base from which-dc nds a pivot or spindle 5 journaled in antiiction' bearings in the head or body 6 of the device. This-head 6 is in the form of a substantially rectangular block having a rounded forward end formed with a transverse horizontal opening 7 and a square rear end formed with a vertical opening 8 for the spindle 5.

e body 6 concentric with the opening 8 are raoeways 9 for the race tion of annular series 'of bcarmg cone bearing 11 tion of the spindleand tho'lower senes enballs 10. 'lhe upper series of balls engages a formed upon the upper porgages an adjustable cone ringer bearing 12 secured upon the threaded lower end 13 of the spindle as clearly shown in Figs. 2 and 3. In order to insure perfect electrical connections between the trolley 1 and the trolley pole 1 preferably provide contact springs 14, 15 am 16. The springs 14, 15 are similar mama net: 1.7, 1907.

inner faces of the arms 3 of the fork as shown in Figs. 2 and 3 and their upper ends. are apertured asat 17 to receive the bolt 3 and are adapted tobear against the sides ol the trolley 1. The spring 16 is secured at its for ward end upon a lug. or projection-l 8forined upon the top of the body 6, and the free end of said spring projects betweenthc fork arms 3 and bears upon the enlarged base portion of the fork as clearly seen in Fig. Upon reference to said figure it will be noticed that the lug 18 also serves asa stop to limit the rotary movement olithe trolley fork 4, but permits the same to have sullicient rotary movement to enable the trolley to properly engage the trolley wire when the car turns a corner. The opening 7 in the body 6 isfor the rcception'of. a bolt 19 which adjustably secures the bodybetween the arms 20 of a yoke or fork 21 from the trolley pole 22 and which also serves to adjustably support a wire guard or deflector 23$ Formed upon the side faces of the body concentric with the opening 7..are annular series 24, 25 of radially extending V shaped teeth or serrations. The teeth 24 upon one side are adapted to be engaged by a similarseries of teeth 26 formed upon one face of a lockin washer 27 which is adapted to receive the bolt 8 and has formed upon its opposite side at diametrically opposite points outwardly projecting fingers 28 adapted to engage the opposite edges of one of the arms 20 of the yoke 21. The other series of teeth 25 are engaged by a similar series of teeth 29 formed u on one face of an arm 30 which is connecte( to and supports the deflector 23. The body of the latter is preferably in the form of a straight bar which is arranged in an upwardly and rearwardly inclined posh tion so that its lower end prince-ts Into the .yoke 21 and its upper end terminates be heath the top of the trolley wheel l as shown in Figs. 1 and 2. It will be seen that byprcyiding the teeth 24, 25 on the body 6 and the teeth 26, 29 on thcwasher 27 and the deflector, respectively, and arranging said washer and deflector on the op osite sidesof the body, the nut 31 of the iolt 'l when tightened will effectively clamp said parts together and between the arms 20 of the yoke 21. Whenthe nut 31 is loosened it will be seen that the body 6 may be swung vertically upon the bolt 7' and that the do 'llector 23;; m be similarly adjusted in a es tioalpianei It Will be also'noted that this connection is sim .le, strong and durable and that it permits tile parts to be readily sep arated for adjustment, repairs and the like.

From the foregoing detailed description. taken in connection with the accompanying l drawings ity is thought that the construction, l operation and advantages of the invention will be readily understood Without a morr l ext-ended explanation.
