- This invention relates to a sliding trolley or shoe for electric trains and cars and an object of the invention is to provlde a trolley 1 -shoe wheel which will provide a large surface contact on'the trolley to prevent burng out the shoe and thus to prolongv its life. I V H J j I A further object is toprovide a novel arrangement whereby in backing up the shoe 10 may be kept in long line contact with the p trolley.
Referring to the accompanying drawings which are made apart hereof and on which similar reference characters indicate similar -5 parts,
I 'liigure' leis a side elevation showing the' position of the device when the car is in forward movement,
FIDUI'G 2, a side elevation showing line 4 -4 of Figure harp which is attached to the upper end of a I trolley pole. This harp has'a pair of forks 11 and 12 in which a spideror frame 13is 14;, and is permitted an oscillating motion which motion islimited by stops 15 and 16* on the-spider which engage the harp at corresponding steps 17 and 18. A contact shoe 2 e '19 has a depending lug 20 which is pivoted at 21 to ca lug 22 on a short lever 23 which is pivoted .on thepin 14. The arm 22 to which the shoe is pivoted is permitted an oscillatory movement;
When the car is traveling forward, friction in the shoe 19 will'hold it to the position I '4L5fSl1OWIllI1 Figure 3. When in this position to only a single point on the wheel and onthe The shoe 19 is grooved as shown at 26 to receive a trolley wire 27 wire' This tends to burn boththeiwirje and e thewheel at starting of the car. the long line contact furnished by device the danger "of 1 burning the surface "of the: shoe A and of thefwire is avoided? Inord'er tofin sure a good 'electrical contact-' between the shoe; 19 and thei,harp a flexible cable 29 is" -se ured=-at 3O totheshoe'and at 31 to the 1.
harp. For providing contact in ireverse Q motion of the'car acontact belt 31 is mount-F6 ed on rollers '32 and '33 which rollers are pivoted on pins 34 and 35 mountedin the rear of the spider13'. v
In operation when going vforward the harp 10 will be biasedin the direction'of the e arrow 36 in Fi'gurel to hold the shoe 19 in contact with-the trolley, and friction on the shoe will hold the shoe in the rear-position with the arm 22 toward the rear. When the car is reversed the shoe 19. will slide for-" ward, at which time the, spider 13 "will further swing on its 'pivot 14 to the position shown in Figure 2'. When in-this position the'trolley 27 will ride on the top'of the belt 31. The tension of the harp 10 will 2 still be in the directionof the arrow- 86 but the reverse motion of the car will hold the spider in the position shown in Figure 2. The belt 31 provides a long line contact with the trolley 27 and provides a rolling contion'but does away with thedangerof burning out portions of the trolley shoe,or burning the trolley wire, such as occurred with V, I trolleys having a single trolley wheel whi art 7 g in the thatvarious changes may be made in my device without departing from the spirit to of the invention and therefore I do not limit myself. towhat is shown in the drawings I itact as well, This not only eliminates fric- H mounted. The spider 13 is pivoted on a pine and described in the specification, but only e as indicated in the appended claims.
Having thus fully described my said invention,'whatIclaim as new and desire to secureby Letters Patent, 7 I c 7 -1.'A sliding trolley" comprising a harp,
