T e energize the coil 3. When the circuit, through conductor 13 connects the shoe 12 with the posithe actuating coil 3, is closed, the movement of tive side 14 of the electric light circuit in which the armature 7 toward the coil 3 will cause the is a lamp 15. On the opposite side of the block rack 9 on the sliding member 8 to engage with 11 is a counter and recorder circuit contact shoe the teeth on the constantly rotating drum 10, n0

which elevates the sliding member at a constant speed to contact successively the

terminals

19, 20 and 21.

The distance the sliding member will travel depends upon the time that the actuating coil 3 has been energized; that is, the time required by the elevator to answer a waiting passenger's signal. When the sliding member 8 has reached its highest point, it will ride on the lowest notch of the rack 9 and will be held in that position until the armature 7 is released through the deenergizing of the actuating coil 3. When the armature 7 has been released by the coil 3, and the sliding member 8 has been thereby released from the drum 10, the member 8 will be immediately returned to its lowest or initial position by the action of the force of gravity.

When an armature 7 is drawn toward its actuating coil 8 after the same is energized by its respective hall signal relay, the respective lighting circuit is instantly closed by way of

wires

14 and 13, the lighting contact shoe 12, the terminal bar 19 and the wire 18, thereby causing the respective light 15 to give a steady signal indicating that a passenger is waiting for service at the floor represented by that signal. When a definite, predetermined time-interval has elapsed, the shoe 12, being constantly moved upward by the coaction of the sliding member 8 and the drum 10, is pushed past the terminal bar 19 and comes into contact with the terminal bar 20.

In circuit with the terminal bar 20 is a flasher 22 with alternating long and short contacts giving dot-and-dash flashes on the signal light 15, indicating that a certain predetermined interval has elapsed since the waiting passenger first called for service. When the contact shoe 12, in its upward travel leaves the terminal bar 20, it comes into contact with the terminal bar 21. In circuit with the terminal bar 21 is a flasher 25 arranged with contacts of equal width to give a uniform dot signal, thereby indicating the lapse of a second predetermined time-interval since the waiting passenger's first call for service.

When the contactor actuating circuit is opened, and the armature '7 is released by the coil 3, the sliding member 8 falls away from the driving and elevating drum 10 and the contact shoe l6 strikes the counter and recorder circuit terminal bars directly opposite the lighting circuit terminal bars with which the shoe 12 has contacted. For example, if the shoe 12 is in contact with the terminal bar 20 at the instant the actuating coil 3 is deenergized through the opening of the actuating circuit relay connected to the

leads

4 and 5, as caused by an elevator car stopping at the floor from which the signal originated and automatically closing the circuit through the contacts 41 and 42, and the sliding member 8 falls away from the driving drum 10, the contact shoe 16 will strike on the terminal bar 28, thereby actuating the counter and recorder operated by the coil 31 and thereby recording the lapse of the predetermined timeinterval as represented by the

terminal bars

20 and 28. Y 1

In an ordinary installation of this device, a signal light 15, a sliding member 8 with two contacts l2 and 16 mounted thereon, and an actuating coil 3 coacting with an armature 7 would be furnished for each floor of the building. One driving drum 10, one of each type of flasher, one set of terminal bars each, for the lighting and registering circuits and registers for each timeinterval to be indicated would'be furnished for each bank of elevators.

The assembly of this equipment, with the exception of the signal lights and the other registering devices, is arranged in a compact form, preferably as a unit as shown in Fig. 3, comprising a single drum 10 of suillcient length to accommodate the desired number of sliding members 8, a plurality of sliding members arranged parallel to each other and in a single row parallel to the axis of the drum, terminal bars and flashers. Each sliding member with its supporting armature 7 is arranged transversely of the drum axis and adjacent the drumperiphery as shown in Fig. 1. An actuating coil 3 is provided for each sliding member and armature and is electrically connected to a respective hall signal switch relay 38 so as to be energized when the said relay is closed by operation of the hall signal switch or button 39. In the form shown the terminal bars are arranged parallel to each other, above and to one side of the drum 10, in spacedpairs extending parallel to the drum, and are disposed so that the sliding members 8 and the

contact shoes

12 and 16 will travel between them and successively contact one bar of each pair. accordingly as they are traveling upwardly or downwardly. One pair of terminal bars is provided for each time interval that is to be registered and each bar is of sufl'icient length so that it can be I contacted by all of the sliding members. The

flashers may be arranged adjacent the drum l0 and are preferably driven by the same driving means actuating the drum. The drum driving means shown is a constant speed electric motor 43 properly geared to the drum so as to rotate the same at a definite predetermined speed.

The signal lights, one representing each floor, would be installed in a convenient place and arrangement to inform the elevator starter of the time a passenger has been waiting for elevator service, and the counters and recorders, one of each for each predetermined time-interval, would be installed in a location convenient to the manager of the building.

The unit comprising the driving drum, with flashers and contactor equipment would all be located at one place, either in the basement or the building or in the elevator equipment penthouse.

When vthe hall signal switch or button 39 on a certain floor is operated by a waiting passenger the respective coil 3 is energized and its armature 7 is actuated causing the contactor shoes to 130 be moved, at a constant speed, transversely of the terminal bars. Each time a terminal bar is contacted an individual circuit is completed and a means is actuated to register the particular time interval represented by such terminal bar. 135

With this arrangement the elevator starter may be constantly advised by means of lights as to the floors on which passengers are waiting for service, as well as the time-intervals that the passengers have been required to wait. Also 40 the manager of the building may be constantly advised by means of counters and recorders as to the class of service the elevator system is giving as indicated by the total number of the different predetermined time intervals that have 5 elapsed while passengers on all floors oi the building have waited for service. The graphic) recorder is arranged to show the time of day that each lapse of any of several predetermined "time intervals has occurred.

within the spirit of their meaning, the means severally or collectively to indicate, record and count; and the acts of indicating, recording and counting.
