` To'cZZ 'w/iom'it 'may concern: y

, Be it known 'that I, JOHN Tini, a subject ofthe King of Hungary, residing at' East Columbus, in the county of Franklin and have invented certain new and useful Improvements in Trolleys, which the following is a speciication, reference being had therein to the accompanying drawing.

Thisinvention relates to trolleys, and the objectsv tliereotl ,are to provide a device of such class which shall be comparatively simple in `its construct-ion, strong, durable, eiiieient in its use, having means for reducing the seperation of the trolley wheels from the conductor to a minimum and'for quickly and jcon'reniently positioning the trolley against Aand releasing it from the conductor,

. l and comparatively inexpensive. to l manu- 20 i I facture.

'th the foregoing and other objects in View, the invention consists of the novelconstruction, combination and arrangement of parts as hereinafter set forth and illustrated in the l,accompanying drawings wherein is shown the preferred embodiment of the invention, but it is to be understood that changes, ifariations, and modifications can be resorted. t' which fall withinthe scope ofthe claims hereunto appended. l

1n the drawings wherein' like lrei'erence charactersl l vdenote corresponding parts throughout the several viewsf-f-Figure 1 is a'rear elevation of a trolley in accordance with this invention, Fig. 2. is a side elevation, Fig. is a plan of the top ofi the trolley, Fig. 4 is a plan of the trolley harp, and Fig. 5 .is a cross sectional view of the harp.

A trolley in accordance with this invention comprises a pole for supporting the harp; a harp carrying a plurality of trolley wheels, a retaining device for Vdie harp whereby the trolley wheels are detacliablyA coupled with the conductor so as to. reduce to a minimum the separation of the harp from .the conductor during the` travel of the trolley, and

a releasing device to facilitate the separationv of the trolley from tlie-conductor when occasionso requires. I

Referring rto thedrawings in detail, the p ole comprises a lower section 1 adapted to behcoiinected iii a known manner to the car and having a biturcated uppei'end Pivotally connected by lthe pin tothe bifurcated Specification of Letters Patent.

end 2 of the section 1 is the upper section 4 of the pole. The sections 1 and 4fextend at an vinclination but in opposite directionsV Patented Nov. 8, 111910.' lApplication tiled August 14, 1909.I Serial No. 512,908. v r V' y imrrnn srApusraTENT OFFioE.

with'respect to each other. The section 41s .reduced at its'lower end as at' 5 and the said reduced 'end' extends into the 'bifurcated upper end of the sectiony 1. Attacheduat its lower ends as at G to the section lfand ex tending around the section 4 is a stop oke t 7 for limiting the upward movement o! the section 4 with respect to the section 1, dueto vthe action of a pulling spring 11` whicliiis connected at one end to an*k eye 13 and-at its f other end to an eye 12. The latter pro'ectsr from the' lower end of the'gisecti'on 4 an the former is attached to tliefsection 1. Inter` posed vbetween the sectionsg'l and 4 and connected at one end to ank eye 10 which prof jects `from the section 4 and at its other end to an eye. 9Aw1iich projects from the section 1 is a cushioning spring 8. The upper end of tliewsection 4 is provided with alateral protuberance 15 which constitutes asto'p for a purpose to be presently referred to.

The trolley harp consists of a U-shaped body portion 16 provided with a depending arm 17. which is ertured end 18.v The Vyoke 1.4 st-raddles the reduced end 18 of theari'n 17 and extending through the yoke anda'educedend -18 ofthe' 19, the function of which is* to pivotally-connect the arm to the yoke.

arm 17 isapin The protuberance' 15 constitutes a means for' limiting the movementfvof the' harp in one direction on its pivot as is eyideiit, and the movement of the harp upon its pivot in the formed with *a reduced ap-y opposite direction. is limited by the inner wall of the yoke 14. Formed integralwith the body portion 16 are four vertically-e'x- .tending arms which are arranged in pairs,

the arms of one pair being indicated by the reference character 2.0 and the a-rms of the other pair by the reference character '21.

Each of the arms has an enlarged upper-end A' as at 23.- Tlie harp is furthermore provided withV four longitudrnelly-extending arms, these arms/are dis..-

22, which. is apertured posed at right angles with'respect to the ver- 'Y tically-extending arms and are arranged atv the endsof the body portion 16 andthe said f longitudiually-extending. arms are further-- more arranged in pairs, the arms of onepairff being indicated by tliereference cliaracter'Qlii and the arms of the other pair by the referencer character ach of the longitudinally-exi tending arms has its free end providedwith an opening 26. The harp furthermore comprises r. four laterally-extending arms which are formed integralwith andproject at right angles with respect tothe longitudinally-ep' tending arms, said laterallyextending arms are arranged in pairs,'the arms of one pair: being -iiiftilicated by the reference character 27 1'0 and the arms of the other pair by the referf ence character 2 8, yandeach of .the laterally-- extending arms has its -upper face formed with'a vertically-disposed lug 29. The open- Y ings 26Wof thearms 24l are arranged in aline.-l 'ment andthe openings 26 of the arms 25 are. arrangedin alinement, and journaled iii the openings of the arms 24 is ashaft 30, and journaledin the openings of the arms 25 is a shaft? 31, and mounted upon each-of said.

' curvedfretaining arms which areadapted to project fove'r the trolley wheels and abutind 2 are tipaintained in such position so as to- `pre vent the Ltrolleywheels or harps from jump ing above the conductor 33.. The retaining *arms are-arranged in'pairs, the arms of one pair being indicated'` by the reference character34 and the arms of the other pairby 35 the reference character 35. Each of the arms 34 'is provided 'atits inner -end and u onl its outer face with a collar 36, which a utsfagainst the enlarged en'd 225i an arm 20 land is mounted'uppn a pivot 37 which "40 extends through the opening 23 in the enlarged upper :end of the arm 21, and by such anni-fran ementthe arms 34 are pivotally.
