MoNoRAI L TROLLEY, SYSTEM.
Application filed December 22, 1927. Serial No. 241,917.
My invention relates to improvements in electrical equipment for .mono-rail trolley systems of the two conductor type, such as are used for traveling electric hoists, cranes, etc.
The l' invention aims to provide means whereby a poly-phase current may be used in such a system. i
The invention further aims to provide means whereby such poly-phased current may be used in a trolley system having its track and conductors in the form of a loop in which the motor carriage makes the circuit of the loop and returns upon the same track by which it entered the loop.
With these and other objects in view, the invention includes the novel system hereinafter described and particularly defined by the appended claims.
In order that the invention may be better understood, reference is made to the accompanying drawings, in which:
Figure 1 is a diagrammatic view illustrating the arrangement of circuits with the mono-rail appearing in section and the traveling carriage in elevation and shown conventionally, and with the reversing switch in one position.
Fig. 1 is a detail view showing said switch in reverse position.
Fig. 2 is a diagrammatic view of the loop.
Referring by reference characters to this drawing, the numeral 1 designates the monorail from which the carriage 2 is suspended by means of the wheels 3, which parts, as they are of well known construction, are shown conventionally and need no further description.
4 and 4e designate the two conductor bars or feeders and 5 and 5 the current collectors traveling in contact therewith to keep the motor in connection with the source of elec tric energy.
To make it possible to use such a two conductor mono-rail system for poly-phase- (lriven traveling hoists, I provide the carriage with a poly-phase motor of known design propelling the carriage in the customary manner, in conjunction with a source of polyphase (two or three phase) currents indicated conventionally at 6, with an interposed insulating transformer 7 having primary and secondary of equal voltage, the mono-rail being connected to serve as the third leg of the multi-phase system, and being grounded.
In order to make possible the use of such a poly-phase equipment on a two conductor system having a closed loop such as shown in Big. 2, I provide a reverse phase relay 8 operating through switch 9 to control a double throw magnetically operated switch 10 to reverse the motor currents.
To this end the two members of the switch 10 are electrically connected respectively to the armature and field or stator of the motor by lines or conductors l1 and 12.
Said switch members comprise upper arms 10 and 10 cooperating with contacts 21 and 20 respectively, and lower arms 10 and 10 cooperating with contacts 13 and 14, the arrangement being such that when the switch arms 10" and 10 are in closed relation to contacts 21 and .20, the other arms are in open position and vice versa.
The contacts 13 and 14 are electrically connected to the collectors 5 and 5 respectively by conductors 15 and 16, which conductors are also connected to the reverse phase relay 8 by branch conductors 17 and 18, said reverse phase relay having a ground connection (to the mono-rail) via conductor 19.
Contacts 13 and 14 are also electrically connected respectively with contacts 20 and 21 (by crossed or reversing wires indicated by dotted lines, Figs. 1 and 1 which cooperate with the switch arms 10 and 10 as aforesaid.
Said contacts 20 and 21 are connected by conductors 22 and 23 to the contacts 9' and 9 of the switch 9, line 23 including the electro-magnetic coil 24 which operates reversing switch 10.
The feeders 4 and 4. are interrupted at points adjacent the junction of the return end of the loop with the main line as indicated at 4" and 4.
Assuming the carriage to have been moving on the track and to have entered the loop (position A traveling in the direction of the arrow, switch 9 will, through the action of relay 8 controlled by line connections 17 and 18 to the feeders and third leg ground connection 19, be in closed position, thereby closing branch circuit 2223 through electro-magnetic coil 24, whereby the switch arms 10 and 10 are in closed position relative to contacts 21 and 20, and arms 10 and 10 are in'open position as shown in Fig. 1. Thereby lines 15 and 16 are put in connection with lines 12 and 11 respectively by way of contacts 13 and 14, crossed connections therefrom to contacts 20 and 21, and switch arms and 10*.
When the carriage has made the circuit of the loop and is again approaching the intersection as in position A it will be seen that the relative position of the conductors are re-' versed. As the collectors cross .the gaps 4, 4", the reverse current encountered causes the reverse phase relay to open the circuit at 9, 9", whereby magnet 24 is deenergized and switch 10 operated to open the circuit at 2021 and close it at 1314, thereby revers ing the currents through the motor, as will be readily appreciated, lines 15 and 16 being then connected to'lines 11 and 12 respectively by contacts 13 and414 and arms 10? and 10*.
The switch means (shown conventionally) inay be of the type electro-magnetically operated in one direction with a spring return, or may be of the double throw type, as desired.
While I have particularly shownand described my invention as embodied'in a twoconductor mono-rail system as emplo ed for traveling hoists, it will be understooc that I 1. In a two conduct-or mono-rail system,
a source of polyphase current and an insulating transformer interposed between such source and the conductors, said transformer being connected to the conductors and having a third leg ground connection through the mono-rail, said conductors and monorail forming a loop and the conductors having gaps adjacent the loop, amotor carriage having a reversing switch included inthe motor circuit, and a. reverse phase relay arranged to actuate said switch on crossing the gaps for reversing the motor circuit.
2. In a two conductor mono-rail system, a source of polyphase current, an insulating transformer interposed between such source and the conductors, said transformer being connected to the conductors'and having a third le ground connection through the mono-rail, said mono-rail and conductors being arranged to form a loop,-and the conductors having gaps adjacent the loop, a motor carriage circuit having a reversing switch included in the motor circuit, a reverse phase relay arranged to actuate said switch on crossing the gaps for reversing the motor cir cuit, and electromagneticmeans for operating said reversing switch, said electromag netic means being controlled by a branch circuit which in turn is controlled by thereverse phase relay.
In testimony whereof, I afiix my signature,
