R.N.DYER. v I ELECTRICAL STORE SERVICE APPARATUS.

No. 395,961.; Patentd Jan. 8, 1889.

UNITED STATES ATENT RICHARD N. DYER, OF EAST ORANGE, NEIV JERSEY.

SPECIFICATION forming part of Letters Patent No. 395,961, dated January 8, 18 89. Application filed July 1, 1887. Serial No. 243,115. (No model.)

To aZZ whom it may concern:

Be it known that I, RICHARD N. DYER, of East Orange, in the county of Essex and State of New Jersey, have invented a certain new and useful Improvement in Electrical Store- Service Apparatus, of which the following is a specification.

The object I have in view is to produce a simple and efflcient apparatus for carrying cash or parcels in stores, the traveling carriers of which will be operated by electrical energy, and which will have outgoing and returning ways.

The invention consists in the several novel features of construction and arrangement,an d in the various novel combinations of parts, all as more fully hereinafter explained, and pointed out by the claims.

In the accompanying drawings, forming a part hereof, Figure 1 is a top view of the way and its electrical connections; Fig. 2, a crosssection through the way, showing a support therefor in elevation; Fig. 3, a vertical section through one of the station turn-tables; Fig. 4, a top view of one of such station turntables; Fig. 5, an end elevation of one of the carriers with its frame partly broken away, and Fig. 6 aview of the commutator and collecting-disks of the carrier.

The way of my apparatus is composed of two metal strips, a b, placed together and parallel and in the same horizontal plane. These strips are mounted at intervals in blocks 0, of insulating material. The blocks for the outgoing and returning ways A B are supported on opposite ends of cross-arms d, which are hung at their centers on pendent rods or pipes C, or supported by standards. This character of support leaves the ways clear on their outer sides for the passage of the depending bails of the carriers. The dynamo-electric machine, battery, or other source of electrical energy (shown in diagram at D) is connected from one pole to the outer tracks, (1., of both ways and from its other pole to the inner tracks, I), of both ways, so that the current passes in one direction through both outer tracks and in the other direction through both inner tracks. The function of these peculiar connections will appear hereinafter. The ways A B are supported by the arms cl a suitable distance apart. At the cashiers stat-ion E the ways are preferably connected bya circular section of track, D, which is not 0011- nected with the electric circuit, it being intended that the carriers as they come upon this disconnected section shall be arrested by suitable dampers or flaps of flexible material hanging in their path of travel, and that when ready for returning to the sales-station they will be pushed out upon the outgoing Way A.

The system illustrated is one having three sales-stati on s, E, E and E although any suitable number can be provided for. For switching from the ways to the stations and vice versa, I prefer to break each way at each station' and deflect it laterally to the station, the carriers for succeeding stations being bridged over the breaks by arched switching-plates, as described with respect to one way in other applications for patents, Serial Nos. 242,818 and 242,819. As shown in this case, the tracks of the ways A'B as they approach each salesstation from the cashiers station are deflected toward each other into the space between the ways. These breaks are bridged at the salesstation E by parallel switching-plates e e and f f and at the sales-station E by parallel switching-plates g g and h h, all of which switching-plates are electrically connected with the tracks a b, so as to form parts of the circuit, as shown by the dotted lines. The plates e c and ff are set closer together than the plates g g and h h, as will be understood from my applications referred to. riers F for stations E and have small switching-wheels '2 t on their driving-shafts k, which are set farther aparton the carriers for station E than 'on the carriers for station E the carriers for station E running between the switching-plates g g and h h without catching. The carriers for station E have no switolling-wheels, but in all other respects are like the carrier shown in Fig. 5. All the carriers have each two brass wheels,G G,mounted on the shaft is, which is divided electrically byinsulation between the wheels. The driving-wheels G G carry soft-iron armatures II II, on which act electro-magnets I I, sup ported by the frame K of the carrier. This frame is electrically divided by insulation at its top, and on one side hangs down below the The cartrack, formin a bail, K,1.'or the receptacle K". This carrier is fully described in one of my applications before referred to. The drivingshatt It has a metal disk, I, on one side, on 5 whichbears a spring, I, insulated from the frame and connected by wires with both magnets. mutator-disk, m, provided with segments ol insulation in m on which comnmtator-disk o bcar springs n a, connected each with one of the magnets. The magnets being set at right angles to each other, they will be energized all rernatcly and will attract the arinaturcsalteri nately, thus producing a continuous rotation 5 of the driving-wheels. Since, as will be explained further on, the carriers have the same relation to the electric circuit, whether on the outgoing way or on the returning way, it is not necessary to shift the connnutator, as described in a former application of the electrical carrier designed to run back and forth on the same way, and hence the coinmutator-disk n] is fixed directly to the sha it 71:.

At each sales-station I provide a turn-table,

L, which is a platform mounted on a turning pipe, L, extending down to the counter. This platform has parallel strips 0 l) to receive the carrier. In the normal position of the turn-table the strips a l) are inline with the o outgoing track A, as shown at stations E and E The carrier runs upon the turn-table from the track A and strikes a pivoted springstop, 0, which is a latch pivoted on a sliding block, 0, backed up by a spring, 0 A cord,

p, extends from the stop 0 down to within reach of the salcswoman. The spring-stop o arrests the movement of the carrier, the circuit through the motor on the carrier bcingbroken as it leaves the way A. As the carrier strikes the stop 0 it rides overaspring-pawl, (1. This is pivoted to a sliding block, q, which is backed up by a spring, extending to another sliding block, A stationary shalt, M,

projects up through the turning pipe L and carries a groovedwheel, r, on its upper end, to which is attached a cord or wire, 1', extending to the slidingbloek (f. A weight,-s, attached to the block q retracts it to itsnormal position.

The operation of these turn-table devices is as follows: The carrier runs in upon the turn-table, rides over the pawl (1, and is arrested by the spring-stop o. \Yhen it is desired to return the carrier to the cashier, the turn-table is turned a half-revolution by the handle a, bringing the turn-table tracks into line with the tracks oi the returning way l3, as shown at sales-station E in Fig. I. This movement causes the cord r to wind up on the wheel r, drawing the block JO forward and putting the spring if under tension against the carrier. The cord 1) is now pulled by the operator, withdrawing the stop o from in front of the carrier, and the carrier forced by the spring (f upon the returning )5 way I}, and is started in its rel urn movement upon such way, so as to cause the electric motor to operate. The turn-table is then ret )n the other side the shaft 7r has a com- I sition of the earrierin shit turned to its normal position. Iiy means of the turn-table the hail of the carrier is brought upon the outside of the return way, where it meets no obstructions, and the carrier is caused to travel with the same end t'orward as when upon the outgoing way, the motor having the same circuit relations upon both ways.
