TROLLEY-STOP.
` Specification of Letters Patent. ,Pwmmmgd Jam, 29, 1911s Application filed May 31, 1916. Serial No. 100,877.
To all whom z't may concern:
Be it known that I, JAMES I-IUDsoNv GRAPE- vINE, a citizen of the United States, residing at Peoria, in the county otPeoria and `State ot Illinois,.have invented certain new and useful Improvements in TrolleyfStops, of which the `following is a full, clear, and
exact description, reference being had to the accompanying drawing, this specification. My invention relates to means for preventing overhead carrying trolleys from running out of or olf of the ends of their tracks.
rI`he object ot my invention is to provide means, which will be automatic in their acforming part lof tion, capable of being operated to permit the removal of the trolley for oiling or repairs, and which after having been so operated will, when released, be restored by gravity to operative position.
@ther objects of my invention will appear and be described as the specification proceeds.
T he novelty oi my invention will be hereinafter more fully set forth and specifically pointed out in the claims.
In the accompanying drawing:
Figure 1 is a side elevation, partially broken away, of an end of a trolley track, its supporting timber, and showing one form of the embodiment of my invention as applied adjacent to the end of the track.
Fig. 2 is an end View of Fig. 1 looking toward the lett.
Fig. 3 is a perspective view of the stop.
F ig. Il is an end View of a modilied form oi stop supporting bracket.
The same numerals of reference are used to indicate identical parts in all the figures.
For purposes of illustration I have shown a swinging stop 1 consisting of the side walls 2, front wall 3, lower lange 4t, cross bar 5, and counterbalance weights 6.
The side walls 2 are perforated as at 7 to receive the bolt 8 Which passes through Vsaid perforations and through a supporting bracket 9, which latter is provided with lateral extensions 10 by meansof which, and the bolts 11, the supporting bracket is secured to the under side oit the timber 12.
The track 18, carrying the trolley 14C, which latter is provided with the depending hook 15, is supported by means of bolts 16 passing through the timber 12 after the usual or any suitable manner.
-to the position shown in AIt is to be understood that the timber 12 the building in which the mechanism is mounted though the support for the timber l2, not forming any part of or affecting my present invention, is not shown.
To adapt my device for use in connection with trolleys which `are wider than the one shown, the supporting bracket 9 may be provided 'with dependingears 17 as shown in Fig. 4t, instead of a single wide depending lug or eye as shown in Fig. 2, and the end wall 3, bottom flange 4, and cross bar 5 of the stop 1 may be lengthened by an amount corresponding to the increase in widthof the ksupporting bracket.
In its normal or operative position, shown in full lines in Fig. 1, the end wall 3 of the stop l lies adjacent to and across the end of the track 18 to eectually prevent the trolley 14 from running out of the end of the track and falling to the flioor, thereby dropping the load which may be supported by the trolley. When it is desired to remove the trolley from its track for purposes of oiling orV repairs, or when it is desired to place other trolleys in service the operator uses the bottom tlange 4 of the stop l as a nger hold to partially rotate the stop on the bolt 8 to the position shown by the dotted lines in Fig. 1,thereby bringing the end wall 3 downwardly away from its position at the end of the track and permitting the removal of the trolley from its track or the introduction of other trolleys thereto, whereupon the operator releases his hold upon the stop and the stop immediately returns full lines in Fig. l.
To prevent the stop l to a point from which it would not return by gravity, the cross bar 5 is provided and so shaped and located that it forms a limit for the movement of the stop by coming in contact, when the stop is operated, with the head of one of the bolts 11, or the cross bar 5, may be located in such a position-that it will come against some other stationary part to act as a movement limit.
While I have shown the stop as applied to a trolley having a track in the form of a channel it is evident that by modifying the method of mounting, the stop may be applied to other forms of trolleys with equally good results.
from being turned Il t) (l lill@ Having thus fully described my inven# tion, I claim:
1. A stop for trolleys comprising a piv-V otal mounting for the stop,V said mounting being beyond the end of a trolley track, a stop structure, mounted thereon and normally occupying a position slightly beyond v the end of a trolley track in such manner stopmounted on said'member, and means for operating said stop. l
A trolley'stop comprising a ,member located beyond theend of a trolley track and separate therefrom and affording a pivotal mounting for a stop, a gravity maintained stop mounted on said member, means for operating said stop, and a movement limit carried thereby 1n such manner that when s aidstdp is operated to a point at which the movement limit becomes effective the stop Will return to operating position by gravity. 4. A trolley stop comprising a counter- Weighted stop structure mounted beyond the end of. a trolley track, an end Wall thereon adapted to be maintained in operative position adjacent the end of the track by a counterweight, a linger-hold for operating the stop, and means for supporting the stop structure adjacent the end of a trolley track. 5. A trolley track comprising a pair of ap'ertured side Walls, an end Wall normally lying adjacent a trolley track, a bottom flange affording a finger-hold for operating the stop, a cross bar forming a movement limit, counterweights for normally retaining lsaid end Walls in operative position, a supporting bolt or pin passing through the perforation in said side Walls, and a supporting bracket for said bolt or pin.
