SPIEGIFIUAEEIUN forming part of Letters Patent No. 668,151, dated February 19, 1901. Application filed May 15,1899. Serial No. 716,889. Noni-.1110

To all It'll 071D it In/my concern:

Be it known that 1, MAX D. BARON, acitizen of the United States. and a resident of New York, in the county and State of New York, have invented a certain new and useful Improvement in lrolley-Switches, of which the following is a specification.

This invention relates to junction-pieces adapted for use in connection with trolleyconductors, and designed to connect the trolley-conductors together at the gaps formed in said conductors at crossings, switches, the.

The purpose of the invention is to provide in such junction-pieces a switch. and more particularly a switch adapted to be operated automz'ttically by an approaching trolley, whereby the gaps in the trolley conductors may be closed to afford a continuous even path for the trolley across the junction-piece. By means of my invention the trolley is enabled to cross the junction-piece without the liability of jumping off.

In the accompanying drawings, forming part of this specification, and in which like numerals of reference designate corresponding parts, l have shown three different embodiments of the invention designed for diiterent uses.

Figures 1 and 2 show, respectively, a side elevation and a bottom plan of my device designed for use and connected with the trolley-conductors at a switch or turnout. Figs. 3 and -i show, respectively, a side elevation and a bottom plan of my device adapted for use and connected with the trolley-conductors at a crossing where the traffic runs in both directions on each trolley. Figs. and b show, respectively, a bottom plan and a side elevation of my device adapted for use and connected with trolley-conductors at a crossing where the traffic runs only in one direction on each trolley.

Referring now to the construction shown in Figs. 1 and 2, 1 the body of the j unctionpiece, having three legs 2, 3, and 4 and connected, YQSQGCElVtBlDQWlhll the wires 5, 6, and 7. The wires 5 and 7 constitute one trolley-conductor, which has a gap therein between the legs 2 and i. The wires 5 and 6 constitute another trolley-conductor, having therein the gap 8 between the legs 2 and 3 of the junction-piece. 9 is a movable switch adapted when in one position to close the gap in the trolley-conductor 5 7 and when in its other position to close the gap in the trolley-com ductor 5 6. In its best form this switch 9 is pivoted at one end to the body-piece 1 by means of the pivot 10. Secured to the pivot 10 is an arm 11, connected by a link 12 to a stud 13, carried on the medially-pivoted lever 14:, pivoted at 15 to the opposite end of the junction-piece. The opposite ends of the lever let are provided with yielding points or springs 16 and 17, respectively. The bodypiece 1 is provided with a slot 18, in which moves a pin carried by the switch 9. The nut 19 forms the upper head of this pin. The ends of the lever it constitute the strikingpieces, which are struck by approaching trolleys on the conductors to operate the switch 9. These striking-pieces are so arranged with respect to the conductors that when one extends in proximity to its trolley-conductor so as to be struck by a trolley thereon the other will be a sufficient distance from its trolley-conductor to be cleared by a trolley. From the construction described it will be apparent that when a trolley approaches the junction piece on the trolley-conductor 5 6 in the direction of the arrow, as shown in Fig. 2, it will strike the spring 17, secured to the adjacent striking-piece of the lever 14, and move the switch so as to close the gap 8 in the trolley-conductor 5 6. When a trolley approaches the junction-piece on the trolleyconductor 5 7 in the direction of the arrow, it will strike the spring 16, carried by the adjoining striking-piece of the lever 14, and move the switch 9 to close the gap in said trolley-conductor. Of course if the gap in either trolley-conductor is already closed by the switch the trolley will clear the adjoining strikingpiece for that conductor without op erating the switch. If, however, the striking-piece in this case should be struck by an approaching trolley, it would not move the switch from its position. Thus it will be seen that approaching trolleys on the trolley-conductors 5 6 or 5 7 are able to automatically close the gaps in these conductors, so as to afford an even continuous way over the junction-piece.

Referring now to Figs. 3 and 4, 20 is the body of the junction-piece and is provided with fourlegs 21, 22, 23, and 24, the legs 21 l and 22 being secured to the trolley-conductor l 25 26 and the legs 23 and 24 being secured to the trolley-conductor 27 28. The gap 29 between the legs 23 and 24 and the gap between the legs 21 and 22 are adapted to be closed by the medially-pivoted switch 30. The pivotpin 31 of this switch carries an arm 32, one end of which is connected by the link 33to the lever 34, the link being secured to the stud 35, carried by this lever. The lever 34 is pivot-ally connected with one end of the junction-piece by the pivot 36. The opposite ends of the lever 34, which form the strikingpieces of this 1ever,are provided,respectively, with the yielding springs 37 and 38 and are disposed between 'the conductors 26 and 28. The opposite end of the lever 32 is connected by link 39 to the lever 40, pivoted at 41 to the body 20. The construction and arrangement of the link 39 and the lever 40 is the same as that already described in connection with the link 33 and the lever 34. The ends of the lever 40, which form its striking-pieces, are also provided with springs 42 and 43. From the construction described it will be seen that a trolley approaching on the wire 27 in the direction of the arrow or on the wire 28 in the direction of the arrow or on the wire 25 in the direction of the arrow or on the wire 26 in the direction of the arrow will come in contact with the adjacent striking-piece and move the switch 30 to close the gap at the junction-piece unless the switch is already in a position closing the gap, and thereby affording a continuous even way for the trolley over the junction-piece. If the switch 30 is already closing the gap, the trolley will pass by without coming in contact with the striking-piece. When the switch is closing the gap of a trolley-conductor, the striking-pieces for that trolley-conductor on both sides of the gap will be out of striking position. When, however, the switch 30 is not closing the gap of a trolley-conductor, the strikingpieces for that trolley-conductor on both sides of the gap will be in striking position, so as to be operated by approaching trolleys on said conductor. 1

In Figs. 5 and 6 my device is shown as adapted for and connected with crossing trolley-conductors on which traffic runs in only one direction on each trolley-conductor. In this arrangement 44 is the body of the junction-piece, having legs 45, 46, 47, and 48, connected, respectively, to the wires 49, 50, 51, and 52. The wires 49 and 51 constitute one trolley-conductor, the traffic on which runs in the direction of the arrow, and the wires and 52 constitute the other crossing trolley-conductor, the traffic on which is in the direction of the arrow. 53 is a medially-pivoted switch mounted on the body 44 by the pivot 54 and adapted to close the gap 55 between the legs 46 and 48 and the gap between the legs 45 and 47. Secured to the pivotpiece 54 is an arm 56, connected by the link 57 to the stud 58 on one end of the lever 59. This lever is secured by means of the pivot 60 to one end of the body 44 and between the wires 51 and 52. The ends of this lever 59, which are provided with springs 61 and 62, constitute the striking-pieces for the switch. Trolleys approaching the junction-piece on the trolley-conductors 49 51 or the trolley-conductors 5O 52 will operate the switch 53 to close the gaps of these conductors, if not already closed, by coming in contact with the striking-pieces on the lever 59, the operation being the same as that already described with respect to Figs. 3 and 4.

The body portions of the junction-pieces, as shown in the several modifications, electrically connect the trolley-conductors at their gaps, so as to afford a continuous path for the current, and the switches which close the gaps are not. employed to carry the current across the gaps, but are merely employed to mechanically close the gaps, so as to afford a continuous Way for the trolleys. The links connecting the striking-pieces with the switches in the various modifications are preferably arranged, as shown, above the bodies of the junction-pieces and are thus out of the way of the traveling trolleys.

The trolley or trolley-arm may be variously arranged so as to contact with the strikingpoints, an d no particular arrangementthereof need be herein described or shown.

While I have shown and described herein the preferred embodiments of my invention for the particular uses to which it may be applied, it must be understood that various modifications in the form and arrangement of the parts may be made Without departing from the scope of my invention.
