To allwkomz'tmay cancer-n; I

Be itknown that I ELBY A. Monms, a citizen of the United States, residing at Leetonia, in the county of Columbiana and State of Ohio, have invented certain new;

and useful Improvements in Trolley-Retrievers, of which the Y following is fa specification. I Y

. This invention devices for electric railway cars, and more particularly to a novel improvement in jtrol ley retrievers;

novel trolley pole and stand, of such construction that when the pole leaves the usual conductor wire andjumps upwardly, it-will.

be automatically returned to a safety position, thus preventing thepole from striking the feed wire supports or pole causing consequent damage. s 1

A further object of, the inventioni isto provide .a simple and reliable construction.

inafter more fullyillustrated and claimed.

A preferred and 'practical embodiment of the invention is shown in the: accompanying drawings, in which l V Figurel is a vertical sectional view showing the-general arrangement and structural details of my improveddevice the same be.- ing in its normal conditionj Fig. 2 is a view similar to Fig 1, but showing the relative position of the; trolley pole after it leaves the conductor wireflin full lines, and indicatingthe safety position to which the same automatically falls, in dotted lines. ,I

Fig. 3 is a top plan view of the invention; Similar references designate correspond.- ing parts throughout the several. figures of the drawings. I, 7 In carrying out the. present invention; it is proposed to'provide a base plate 1 of suitable dimensions, which may be readily positioned and secured upon the top of a car, or other vehicle by suitable fastening means.

relates tooverhead trolley his end, the invention -cohte1np1ates ,a

arms, and.

This baselplate is preferably formed with a relatively large centrally located upstand lng bearing boss 2, and a pivot pin 3, which provide a pivotal bearing fora trolley pole stand designated generally as S.

As will be observed from Figs; 1 and 2' of the drawings, thetrolley stand S comprlses a frame including 'a' bottom wall 4:

. provided. with a recess 5 in its under side for receiving the upstanding bearing boss 20f the base plate, and also has an opening 6 for permitting the pin 3 to project intoan exposed. position to receive a suitable clamping. nut '7, for pivotally holding the ent repframe'of the base plate. At thelateral edges of the bottom wall 4 of the frame are provided the upstanding side walls 88,'

which may, for the sake of lightness andeconomy, be of the open or skeleton formation shown, and -provide suitablebearings for the axle bolt 9 of arockable supporting member 10.

As will be observed from *Fig. 3, this supporting-member is preferably formed at its intern'lediate portion with the hub or oppositely disposed bolt receiving sleeves 11',

while one end thereof is forked as at 12 to pivotally receive one end of a springguiderod 13. This rod is surroundedby a coiled compression spring 14, one end-of which abutsagainst the forkedend 12 of the supporting member 10," while theopposite end thereof abuts against a suitable bracket 15 which 1s secured to'the opposite sidewalls 8 of the frame. For the purpose of holding the end of the spring positivelypositioned in. the bracketxl5, the latter is also preferably provided with'the guide pin 16, as will be clearly apparent from. the several figures of the drawing. With this arrangement of the spring 14, it will be apparent-that the same will tend to rotate the supporting member 10 sothat the head portion 17 thereof will have a tendency to swing in a clockwise direction. T 1 a Referring furtlierto the su'pportingmember 10, it will be observed that therhead portion 17 thereof'isprovidedon one side with a hinge knuckle 18, while-the opposite side thereofis provided with the upstanding ears 19 for pivotally receiving therebetween a latchdog .20, which isprovided at one end with a latch shoulder .21, while its opposite end 22 works against the tension of a spring i 22 The hinged knuckle 18 of the support- It will thus be understood that the socket element 23 carrying the pole 24 is hinged or pivoted tothe supporting member 10, and for the purpose of maintaining the longitudinal axes of both the supporting member and the socket element or trolley pole in alinement, the said socket element is provided with a keeper shoulder 26 for en gaging with the latch shoulder 21 ofthe latching dog 20. As will beuobserved from the drawings, theisocket element 23 is further provided withan offset bracket arm 27', the extremity, ofwhich is connected by means of a spring 28vto a suitable eye carried by the supporting member, as will be observed from Figs. 1 and 2. This spring has a tendency to swing the entire pole and socket element 23 .on the hinge 18, which p-' erates to, not only maintain a firm engage me'nt "between the shouldersc26 and 21- but also compels the pole to drop into a safety position, as will hereinafter more fully apable abutment member 31,-which is provided with an abutment head 32 located directly in the path of movement of the head 17 of the supporting member 10, whereby the end 22 of the latch dog 20 carried thereby will engage theisaid head. That is to" say, the yieldable abutment 32 is so arranged with v respect to the supporting member that when" thesame is caused to rotate on it's 7 axis 9 under the influence of the spring 14,

the end 22 of the latchvv dog will be brought against the head 32 of the trip device, thereby rocking thelatch dog against the tension of the spring 22 to disengage the latch shoulder 21 of themember 20 from the keeper shoulder-26 oft'he socket'element;

This trip device is preferably adjustably secured betweenthe arms 88, as will-be observed from the drawings; To provide for this adjustable mounting, the opposite walls are preferably provided with suitable open ings, to permitof therel'ativ'e position of the trip device to be changed to suit various requirements and conditions, whereby the latch willbe operated sooner or later within the limit of movement of the supporting 'member, as circumstances may require,

and, is held in its normal position with respect thereto by means of the latch dog 20 engaging the keeper shoulder 21. When the parts are in this condition, that is when the socket piece is'locked with the supporting member 10, the entire trolley pole is in its normal useful position, as shown in Fig. 1. In other words, with the socket piece and smppoitiiag: member locked together, the 1 spring 14 exerts its full force on the coupled members 10 and 28' to hold tlre'trolley wheel-- on the conductor G. I Iowev'er,

gaged from thekeepershou1='der 26, as shown in Fig. 2,-and' the. trolley pole or standard drops to a substantially horizontal safety position,- Fig; 2.

When the trolley pole reachesthe limit of its upward movement and is substantially vertical, the spring 28 comes into play to positively swing the socket element on the hinge1'8' and pull it'toasafety position without relying on the weight of the-"pole as shown by the dotted lines in to bring it down, thereby positively preventing the same from strikingany of-the trolley wire supports or cross arms of the trol ley plates. After the latch dog 20' has been released from 'it's" engagement. witlrthe keeper shoulder 26', and the trolley pole is' in its fallen or substantially -horizo'ntal that the pole may be again made ready for use by compressing the spring 14 and rotatingi thesu portingmember 10 on its axis 9- a sufficient-distance to permit the dog to again engage theshoulde'r. Y

safetyposition, it will of course beapparent Without further description it is thought 7 that the many features andladva'ntages ofthe invention will .be' readily, understood, and it will of course be apparent that changes in the form, proportion and minor details of construction maybe resorted "to without departing; from the spirit-"of the invention or scope 'of the'appe'nded claim;

I claim: V

A trolley" retriever includinga rotatably supported frame "having opposite side walls, a pole supporting unit consisting of a-pivot' section including an enlarged body portion journaled in the sidewalls of the; frame and having oppositely disposed portions one of which constitutes a spring abutment while the other carries hinge knuckles, and a pole receiving socket section" also having hinge knuckles for cooperating with the knuckles on'the pivot section to constitute a hinged connection therebetween, a pivoted latch carried by the pivot section, a-keep'er -on the socket section for cooperating with said latch, an offset bracket arm also on the socket section on the side opposite the keeper, a spring connecting the extremity of the bracket arm with the enlarged portion of the pivot section, a yielding abutment located in the path of movementof the pivoted latch, and a compression spring arrangedbetween the Walls of the frame and the pivot section.

In testimony whereof I hereunto afiix my signature in the presence of two Witnesses.
