STORE-SERVICE SYSTEM.

SPECIFICATION forming part of Letters Patent No- 303,800, dated August 19, 1884.

A pplicniinn filed ApriH, 1834. (No model.)

I0 all-whom it 71'1/(117/ concern:

Be it known that 1', L'I'JANDRE BOUDREAU, of Manchester, in the county of Ilillsborough and State of New Hampshire, have invented certain Improvements in StoreService Systems, of which the following is a specification.

This invention relates to that class of cashi-arrying or store-service systems comprising inclined ways or tracks extending in pairs between the counters or stations and the cashiers desk of a store, and carriers adapted to run thereon, one track having a downward inclination from the counters to the desk, and the other track a reverse inclination, so that the carriers will run from the counters to the desk, and vice versa, means being provided whereby each carrier, on its way from the desk, is caused to leave the track and descend to the counter at the station from which it was sent, and no other station, while each station is provided with means for elevating a carrier to the track leading to the desk.

I-Ieretofore in this class of storeservice systems the track has been formed to support hollow balls of different sizes, which constitutc the carriers, and has been provided with pivoted traps or sections at the different stations, each trap being adapted to yield only to a ball of a given size, as in theso-ealled Lamson system. This form of track is necessarily expensive, havi mg to be made very accurately and of costly materials. In other and less expensive store-service systems continuous tracks are employed, consisting of rods or wires stretched between suitable supports and adapted to support and guide a grooved pulley on a carrier; but in such systems no provision has been made heretofore for dropping each carrier automatically from the track at the station for which it is intended, and for elevating it from the station to the track extending to the desk; hence the capabilities of the wirct-rack system have not been so great as those of the Lamson system.

My invention haslfor its object to provide a store-service system having continuous tracks of wire or equivalent material, arranged in pairs, extending at opposite inclinations, carriers having wheels adapted to run on said tracks, appliances for automatically removing each carrier from the track when it reaches a point over its own station, and allowing it to several improvements, which I will now proceed to describe and claim.

Of the accompanying drawings, forming a part of this specification, Figure 1 represents an elevation showing my improved system applied to a store. Fig. 2 represents a top view of the same. Fig. 8 represents a side elevation of the appliances at one of the sys terns, the track being shown in cross-section. Fig. l represents a similar elevation showing the manner of elevating a carrier from the station to the track leading to the desk. Fig. 5 represents a perspective view of the combined receptacle and elevator which receives the carrier when it falls from the track. 6 represents a similar view showing the elevator partly raised. Fig. 7 represents a transverse section of the track from the desk to the counter, showing a carrier about leaving the track preparatory to falling to the station for which it is intended. Fig. 8 represents a side view of a part of the track, showing the carrierwheel in the same condition as in Fi 7 Fig. 9 represents a top view of the parts shown in Fig. 8. Fig. 10 represents a transverse sec tion olithe track from the counter to the desk, showing an appliance for arresting each can rier as it approaches the desk, and a guard which prevents the carriers from being displaced from the track. Fig. 11 represents a side elevation of the carrier, showing a toy figure operated by the rotation of the wheel. Fig.12 represents a section on line a; m, Fig. 11. Fig. 13 represents a spiral track adapted to guide a carrier from a given point to another vertically below.

The same letters of reference indicate the same parts in all the figures.

In the drawings, a and a represent two in clined tracks, each preferably composed of a single wire or otherwise formed to present a continuous or uninterrupted surface and support a grooved wheel. The track a is inclined ICO 5, at one side of its grooved tread.

downwardly from the counter or counters b to the desk 0, and the track a is inclined downwardly from the desk tothe counter. The tracks are supported by brackets or hangers d, secured to the ceiling or elsewhere, as may be found convenient.

6 represents one of the carriers which I employ with my improved system. Said carrier is composed of a receptacle, 2, preferably of cylindrical form, a bent arm or rod, 3, secured to the upper end ofthe receptacle,and a grooved pulley, 4, journaled on a bearing formed at one end of said rod. The pulley is adapted to run on either track, and the receptacle depends from the pulley below the track, as shown. The pulley is provided with a flange, The flange 5 of each carrier has a different diameter from the flanges of all the other carriers in the series.

Under the track a, leading from the desk to the counter or counters, are a series of switches, f, which are placed at different distances from the track, the one nearest the desk being separated from the track by a wider space than the next, and so on, the space decreasing at each successive switch. The first switch is placed at such a distance from the track that it will come in contact with the largest flange 5 when the carrier having said flange reaches said switch, and will raise the wheel of said carrier from the track a, as shown in Figs. 7 and 8, the carrier being then entirely supported by the switch. The switch is grooved on its upper surface, as shown in Fig. 7, and is curved as shown atf, Fig. 8, so that it will guide the carrier-wheel laterally away from the track a, and is then curved downwardly, so that it will conduct the carrier downwardly at one side of the track to a basket, 9, located at the lower end of the switch, the carrier dropping into the basket, as hereinafter described. The next switch is arranged to raise the flange 5 next in. size, said flange passing overthe first switch without touching it, and so on, each flange 5 being acted on only by its particular switch, there being as many switches as there are carriers.

To enable the carriers to pass by the switch or switches not intended to displace them, I cut a passage, f through each switch in its curved portion f. The rod 3 of each carrier, designed to pass by the switch, passes through said passage without striking the switch.

To prevent any flange 5 from passing through the passage f in the switch on which it runs after leaving the track, I provide the rod 3 of the carrier to which the flange pertains with a protuberance, 6, which is arranged to bear against one edge of the switch, as shown in Fig. 8, and cause the carrier to follow the lat eral curvature of the switch. In each carrier the protuberance 6 is so arranged that its lower edge is flush with the lowest point in the periphery of the flange 5, so that said protuberance will bear only against the switch, which acts 011 the carrier to which it pertains.

die, 13, or otherwise.

It will be seen from the foregoing that each carrier, as it is placed by the cashier on the higher end of the track a, will travel along the track until it reaches the switch intended for it, and will then be raised from the track, moved sidewise, and guided to its basket bysaid switch. The carrier having the largest flange will be acted on by the first switelnwhile the carrier having the smallest flange will be acted on by the last switch. Each basket 9 is composed of a fixed section, 7, and a vertically-movable section or elevator, 8. These parts, when the movable section is depressed, as shown in Fig. 5, constitute a basket,which is elliptical in cross-section at its top, its sides converging to a rectangular frame or opening,

9, at the bottom of the basket, said frame being secured to the movable section or elevator 8. Each carrier is provided with a rectangular portion, 10, at its upper end, adapted to fit and rest upon the inner sides of the rectangular frame 10.

I prefer to make three of thesides ofthe 0 frame 9 of flat plates of considerable width-say an inch or morewhile the fourth side is made of a single rod or wire, as shown in Fig. (i. Thefiat sides are beveled inwardly, and the sides of the rectangular portion of the carrier 9 5 are correspondingly beveled; hence the frame.

9 constitutes a seat or support on' which the rectangular portion of the carrier rests when it drops into the basket. The described form of the basket and of the frame 9 causes the carrier to always assume a given position when at rest in'the basket. so that when raised, as hereinafter described, by the elevator it will be sure to be in position to engage with the track. \Vhen the carrier is in place in the basket, its cylindrical receptacle projects below the bottom of the basket, said projecting portion having a door or slide, 12, adapted to be opened. by the attendant by turning a han- Access can thus be had no to the interior of the receptacle without removing the earrier from the basket. The elevator has ears or guides adapted to'slide on parallel vertical guide-rodsj j, and is provided with an elevatingcord, is, passing upwardly over a pulley, Z, and downwardly within reach of the operator.

When a carrier is to be raised by a salesman to the track a, a pull on the cord k raises the elevator, which is so arranged with reference to the track a that as the carrier rises an inclined portion, 14, formed 011 the rod 3 strikes the track a and causes the carrier to tip sidewise, as shown in Fig. 4, the body of the carrier projecting outwardly under the wire which forms one side of the frame 9 until the wheel 4 of the carrier passes above the track a, when the carrier tips back to a vertical position by gravitation, and thus moves its wheel over the track a, as shown in Fig. 4", so 1 0 that as soon as the elevator falls and leaves the carrier the wheel is supported by said track and the carrier commences to travel toward the desk. The elevator falls back to the fixed section of the basket, a rubber buffer, m, at the l automatic shuntingdeviees to engage with said lower ends of the rods j j relieving the jar attending its stop when it reaches the basket. The baskets maybe supported by the same brackets or hangers that support the tracks, as shown in Figs. 35 and it.

It will be observed that the track a, lea-ding from the counter to the desk, is notprovided with switches, the carriers placed on said track at any point running directly to the desk. The desk may be located on the same floorlcvcl as the counters, thus obviating thcnecessity of placing the cashier in the heated and impure air at the top of the store. In this case it may be necessary to give the track a downward curve as itapproaches the desk, as shown in Fig. 1. To prevent the carrierwheels' from jumping sidewise from the track on this curved portion, particularly when two or more accumulate at said portion, I provide a guard-rail, a, above thetrack and arranged to stand between the flanges and arms of the carriers. (See Figs. 1 and 10.)

0 represents a movable stop at the end of the track (a to arrest the carriers, so that they will not enter the basket at the desk until the operator moves the stop 0. The cashier is thus enabled to admit the carriers singly and prevent any carrier from entering the basket at the desk when said basket is occupied by another carrier. The stop 0 is composed of a spring-lever adapted to bear against and arrest the arm 3 of a carrier, (see Fig. 10,) and to be moved back to allow the carrier to pass.

In Fig. 11 I have showna toyfigure, p, sup ported by the rod of the carrier and having a connection by means ofa crank, q, and apitman, r, with the wheel of the carrier. lhe figure is moved by the rotation of the wheel and glVS the carrier a novel and pleasing effect.

lli g. 1.3 shows a spiral-wire track adapted to conduct a car between two points, one vertically above the other, as from one story of a building to a lower story. This form affords a gradual incline of considerable length in a small space. The lower coil or coils of the spiral may be enlarged, and the lower coil may be extended horizontally to enable the carrier to lose a portion of its momentum before stoping.

The spiral track may be supported by an upright extended through it and provided with suitable arms secured to a sufficient number of the convolutions of the track.

I am aware that the following features in a storeservicc system have been before used in combination, via: main, side, and branch tracks, a carrier provided between the trackrails with a main flange and a branch flange of less diameter than the main flange, a stationary main-trackdiverting flange placed at such elevation as to be reached only by the larger or main carrier-flange, and a side-trackdiverting ilange for shunting the carrier from the side to the branch track. I do not there fore claim, broadly, thcprovision ot' flanges of diilerent diameters on the carriers and fixed flanges.

I claim 1. In a store-service system, the combination of continuous reversely-inclined tracks adapted to support cmri0r-u*l1ecls, and extending, as described, between the desk and conu ters, switch-rails arranged at ditfcrent dis tances from the track leading from the desk to the counters. and each adapted to raise a given carrienwheel from the track and conduct it first laterally and then, downwardly, receptacles located at the lower ends of the switch-rails and adapted to receive the car riers from the switchrails, and elevators forming parts of said receptacles, adapted to ole vatc said carriers to the track leading to the desk, as set forth.

2.
