STORE-SERVICE APPARATUS.

SPECIFICATION forming part of Letters Patent No. 474,040, dated May 3, 1892.

Application filed April 18, 1888.

To all whom it may concern.-

Be it known that I, JAMES T. COWLEY, a citizen of the United States, residing at Lowell, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Store-Service Apparatus, of which the following is a specification.

This invention relates generally to storeservice apparatus, and while certain features thereof are alike applicable to manykinds of such apparatus the present improvements particularly relate to that class of apparatus wherein a plurality of moving carriers, adapted either for cash or parcels, are automatically arrested at their respective destinations in such manner as not to obstruct the track or way upon which they travel; and the invention consists in certain novel devices and combinations of parts hereinafter fully set forth.

In the drawings, Figure l is a diagrammatic view in elevation of an apparatus embodying the present invention. Fig. 2 is a similar view in plan ofa portion of that shown in Fig. 1. Fig. 3 is an elevation of portio is of the forwarding and return tracks, showing particularly the arrangement of curves connecting the vertical with the horizontal portions of the tracks; and Fig. 4 is a plan view of the end of one of said tracks. Fig. 5 is a perspective view of a portion of the. returntrack and a carrier in position thereon. Fig. 6 is a similar view looking from the opposite side thereof. Fig. 7 is a similar view of the apparatus, illustrating the two tracks, a bracket for supporting them, and a carrier in position on one of the tracks. Fig. 8 is a 1011- gitudinal sectional elevation of the carrier shown in Figs. 5, 6, and 7. Fig. 9 is a perspective view of a carrier embodying a modified form thereof. Figs. 10 and 11 are respectively a cross-sectional and plan view of another modified form of the carrier and track. Fig. 12 is a perspective view, and Figs. 13 and 14 are cross-sectional elevations showing other forms of the carrier and track embodying the invention. Fig. 15 is a plan view of a portion of the return-track at one of the stations, showing particularly the speed-retardcr and Serial No. 271,015. (No niodel.)

delivering-elevator. Fig. 16 is a side elevation of the same. Fig. 17 is avertical sectional elevation thereof, taken on the line 00 a: of Fig. 18, looking in the same direction as in Fig. 16. Fig. 18 is an end elevation thereof. Fig. 19 is a sectional detail of the movable end of the branch rail 50. Fig. 20 is a modified form of the elevator-pocket shown in Figs. 16, 17, and 18. Figs. 21 and 22 are respectively sectional end and plan views of a modified form of the track and devices for returning the carrier thereto. Fig. 23 is another diagram illustrating a track and carriers thereon stripped of all details of construction, and Fig. 24. is a similar diagram hereinafter referred to.

The way is suitably constructed to support the carriers, which in the apparatus shown and herein described are propelled by a contin uously-traveling cable. The said way may consist of parallel rods, as shown, or may be of any usual construction adapted for use in connection with the other features.

An arrangement of forwarding and return tracks B B of the way in a store is illustrated in the diagrammatic views, Figs. 1 and 2, showing parallel tracks leading from .a cashiers desk V upon an upper floor past a station F downward to a lower floor and past stations F F F from which carriers are to be received by means of elevators U of suitable construction and to which they are to be delivered by means of the usual drop boxes or tubes, drop-baskets, or in the specially-constructed devices hereinafter full y set .forth.

The cable E is suitably guided, as fully set forth hereinafter, to travel ina line with each track and passes round a driving-wheel E, operated by a suitable motor, whereby the requisite movement is imparted.

As it will be desired to deflect the carriers from one way unto another at stations, means are provided for this purpose. Thus'in Figs. 5 to 7 upon the return-way B, at or near each station, a switch 12 is arranged adjacent to the way and in position to control the further movement of the carrier, which is provided with a movable engaging piece or post which. I term an engaging-finger 9, which is carried by a shaft 30, mounted thereon.

'Where there are a number of stations and a plurality of moving carriers, graduated contact-pieces of suitable construction are arranged along the track (in conjunction with the switches 12) at each station to actuate the movable engaging-fingers of the carriers to be switched from the track by said switches. In the preferred form, Figs. 1 to 7, inclusive, each track consists of one or more supportingrods 10, along which the carriers will travel, and provided on one or both sides thereof with a side guard 11 to better confine the carriers to the track and prevent them from accidental dislodgment, the rods and guards forming the tracks B B (which tracks are preferably located one above the other) being supported at suitable intervals by a bracket D of any desired form.

The switch 12 is shown in Figs. 5, '7, 12, 15, and 16 as forming a continuation of one of the side-guard rails 11; but it may obviously be independent thereof, as in Fig. 6,wherein only one side guard is illustrated. In either form the switch will preferably extend for a short distance parallel with the way and then be curved and extended away therefrom for any suitable distance and form a portion of a branch way or lead to a station F alongside of the way for receiving and arresting a carrier, as in Fig. 7, or to the drop of a station, as shown in Figs. 1 and 15 to 18, or form in itself .the arresting and receiving device on which the carrier will be supported, as in Fig. 12.

The carriers 0 in their preferred form, Figs. 5 to 8, each consist of arectangular case constituting a receptacle or compartment 13, having a hinged cover 14 held closed against the force of a spring 21 by a hooked end of a pivoted catch 15, carried upon the under side of the cover, which end engages with a stud or pin 16 in t-heinterior of the compartment, and said catch may be moved to one side to engage or disengage said stud by a finger-piece 22, projecting through aslotinthe cover. Of course many other forms of catch may be employed to secure the cover in place.

-The engaging-finger 9, with which each carrier is provided, is shown as forming part of the shaft 30, that is mounted in a bearing 31, so as to be capable of rocking therein, the said finger 9 extending at one end of the shaft at right angles thereto. In one form the shaft 30 is provided with squared portions engaged by a flat spring 2, Fig. 9, so as to hold the finger 9 in its adjusted positions against accidental movement, and at the opposite end forms a contacting-finger8,whichis at an angle to that of finger 9 at the opposite end, so that the latter in the normal position of the shaft extends parallel with the way and out of position to engage a switch 12. The finger 8, however, in said normal position of the engaging-arm lies in the path occupied by one of the contact-pieces 18, arranged along the track and preferably in advan cc of the switch, so that when the said finger Sis struck by its proper contact-piece and moved the engaging finger will be correspondingly moved to a position to engage a switch 12, and thus automatically place the carrier within the control of said switch in its further movement. In

some cases, Figs. 5 to S, the contact-finger, as

shown at 8*, is independent of the shaft 30 and is pivoted to the carrier, so that its inner end may engage with a shoulder 7, carried by said shaft to hold the latter in its normal position against the force of aspring 6, and said finger 8 may be held to duty by a spring 4. The projecting end of the finger 8 extends in a position to strike one of the contactpieces 18, to be thereby moved to release its inner end from the shoulder 7 and permit the shaft and its engaging-finger 9 to be moved by said spring 6 to a position for the finger 9 to engage the switch 12, as in Fig. 6. The contact-finger may, however,be integral with the shaft 30, as before described, and shown in Figs. 9, 10, and 12, to 14.

When the carrier is to be moved along the way by a power continuously exerted, as by the endless cable E, means must be provided for connecting the carrier with the cable and for automatically detaching it therefrom when the carrier is to be stopped or switched from the way. In the present instance there is a catch in the form of a fork 33,preferably carried by the shaft 30 and having flaring prongs 3 3, which catch is arranged to straddle the cable, so that the latter becomes wedged in the notch between the prongs and draws the carrier along with it. The catch is so arranged on the shaft 30 that in the normal position of the latter the catch will be in position to engage the cable; but as the shaft 30 is rocked to move its finger 9 into engagement with the switch 12 by the operation of the finger 8 and a contact-piece 18 the catch will be simultaneouslymoved away from the cable and detached therefrom.

In the preferred construction, Figs. 5 to 8, the catch (supposing the cable E to be traveling in the direction of the arrow) will be inclined slightly rearward, so that the tendency of the cable will be to draw down toward the bottom of the notch, while the catch, when it is moved to free or disconnect the carrier from the cable being suddenly moved in the same direction with that of the cable, will gain slightly thereon and partially free itself therefrom, and by reason of its circular movement will become entirely free from the cable in assuming the horizontal position seen in Fig. 6.

In the construction shown in Figs. 9 to 14 the finger 8 acts as a safety device, loosely engaging, when in its normal position, the side guard 11, so that as the carrier passes a station along the way to which it is not to be directed it will prevent the carrier from becoming accidentally derailed; but when the shaft 30 is moved so that its finger 9 may engage the switch the finger 8 will be also moved to free itself from the side guard 11.,

and hence it will not oppose the movement of the carrier when under the control of the switch.

In adapting a plurality of carriers to travel over the same way to their respective stations it is obvious that the contact-pieces 18 may he graduated in height or position with respect to the

fingers

8 or 8 on the carriers, or the fingers may be graduated in length with respect to the contact-pieces, or both the contact-pieces and the

fingers

8 or 8 may he graduated in size or position, as illustrated in the diagram Fig. 23, in a manner which will be well understood.

The forwarding-track B, leading from the salesmens counters to the central desk, is provided with propelling means similar to the other track, and is also provided with stations with means for permitting the carriers to be readily placed upon the track to pass to the central desk, and instead of employing a second track for forwarding the carriers to the central desk the track may lead from said desk around past all of the counters and return to said desk, as illustrated in Fig. 24. Of course in this case the contact-fingers and contact-pieces must be so arranged thatthe carrier after being placed on the way at any station to be sent to the central desk will not be directed from the way between its station and said desk.

It is obvious that different forms of carriers may be employed without departing from the essential features of the invention, and that different forms of ways may be used, along which the carriers may travel. Thus in Fig. 10 is shown a carrier 0, consisting of a rectangular receptacle 13, mounted between supporting-wheels 24:, which travel upon a track consisting of a pair of flanged rails 25 with a guard 11. These tracks at a station or branch way, as shown in Fig. 11, connect with branch tracks, a portion of the flange on one of the rails being removed to permit the wheels to pass onto said branch tracks when the engagingfinger 9 is moved to engage with a switch 12. If the receptacle be a pendent one, as shown in dotted lines, Fig. 10, the portion a of the main track and the portion 19 of the branch track will each be hinged at w and capable of swinging to one side, the former to permit carriers to pass a station and the latter to permit a carrier to pass onto the branch track.

In Fig. 12 the track consists of asingle rail 20, provided with side guards 11, one of which extends into and forms a switch 12 of the station F. The carrier in this instance is pro vided with a pair of plain wheels mounted to travel on said rail 20, and the carrier-frame between the wheels is provided with the shaft having an engaging-finger 9 and a finger 8 for embracing the switch 12 and the side guard 11, respectively. In Figs. 13 and 14 a similar carrier is illustrated in part, with a rail formed with the side guard 11 integral therewith, forming in the first instance a trough or U-shaped rail and in the other an L-shaped rail.

Of course it is obvious that the movable engaging-finger 9 may be employed independently of the catch 33, in which case other means, as gravity, for imparting a propulsive movement to the carriers may be used.

It should be understood that by the term catch I mean any means that will engage temporarily with the cable, so as to cause the carrier to be propelled thereby until it is necessary to detach it.

hen the carriers are propelled at a rapid rate, it becomes necessary, to avoid shocks, to gradually reduce the speed as the carrier reaches the salesmans position. When a propelling-cable is'used, the speed of the carrier cannot be diminished so long as it is connected with the cable, nor can it be diminished so long as it is in line with other rapidly-traveling carriers. I therefore provide means whereby the carrier can travel upon the track at normal speed until just above the salesmans station and to then gradually but positively diminish its speed, so that it will arrive at the station at a comparatively slow speed. This I effect by means of a track in the form of a gradually-(Iiminishing spiral connected with the main track and with a drop-track leading to the salesmans station. One construction of such a speed-rctarder is best illustrated in Figs. 15 to 18, in which a branch rail extends from a point t) adjacent to one of the track-rails 10, and is curved round and downward vertically through two frames D D the lower end being bent out at right angles before passing laterally through the frame D and a spring 51 tends to force the end of this rail in the direction of the arrow, Fig. 18. This constitutes the trackrail, on which the carrier travels first on a wide curve, which is gradually contracted, and then downward, pressing outthe movable end of the rail, as in Fig. 19, against the force of the spring, which gradually retards the descent of the carrier.

To keep the carrier on the rail, the guard rail at one side is curved outward and downward in the form of two guards 52 53, and two additional guard-rails 54: 55 are also extended from one side of the track above the rail 10, first curved outward and then downward. The rails 52 53 are continued downward below the frame D to form side guards, as shown in Fig. 16, the track-rail 50 extending to the frame D as a front guard, the rail 55 constituting an additional side guard terminating at the frame D while two additional guard-rails 56 56 extend between the frames D D to constitute with the others the vertical portion of the retarding-track.

If desired, the carriers may drop from the open end of the vertical track portion into a suitable receptacle; but I prefer to add a dcflector-track T, whereby the carriers are gradually conducted from a vertical to a horizontal curve, at the end of which is a stop 57,

IIO

preferably supplied with an elastic buffer. As shown, the deflecting-track consists of four curved rails, two of which are continuations of the rails 52 53 and two others 58 58 are attached at the upper ends to the frame D By this combination of rails, which may be differently arranged, I form a retarding-track having a gradually-diminishing spiral at the upper end and extending then vertically; but it will be evident that said track may be in the form of a tube or otherwise made.

The structure may be strengthened byhanger-bars 59 59 60 60, braced by frames or spiders D D the rails 60 60 being connected to a yoke D", supporting the deflecting-track T and constituting the guides of an elevator when one is used.

I have found that a receiving-track having a spiral and a straight portion, as above described, will receive carriers traveling at a high speed and gradually reduce such speed without shock or noise.

Heretofore when motor-cables have been employed it has been customary to place the carriers upon the track and in engagement with the cables by hand. This is not practicable where the track is elevated above the reach .of the operator. I therefore use an elevator constructed to support the carrier and conduct it to a position to engage with the cable and then pass onto the track.

In the construction shown the elevator-carriage K is guided to slide vertically on the rods 60 60, and is provided with an inclined pocket 70, adapted to support the carrier in an inclined position. A section 71 of the lower track immediately above the pocket is movable, so as to be deflected or turned out of the line of said track as the carrier is brought in line with the same. The movable section may be supported to be moved out of line in any of the ways usual in store-service apparatus. As shown, it is pivoted at one end 72 in position for the free end to be struck by the top of the carrier itself, so that if no carrier is in the carriage the track-section will not be lifted. As the motor-cable maintains its position in line with the path of the carrier, the catch of the latter will engage with the cable as soon as the carrier is in position to move onto the track.

While the movement of the elevator-carriage alone might be depended upon to conduct the carrier into position to engage the cable, I prefer to bring the carrier to about a horizontal position before it begins its travel on the track. Thus the pocket may be secured to a rock-shaft 73, Fig. 20, provided with an arm 74, arranged to strike a stop 75 adjacent to the track to raise the pocket to a horizontal position as the carriage reaches its upper position. I prefer, however, to have a stationary pocket with a lifting-finger 76 at the bottom thereof secured to the rock-shaft 7 3, this finger being lifted to raise the carrier in the pocket to a horizontal position and into engagement with the cable. The carrier is thus brought to a horizontal position before beginning to move onto the track and starts without shock or j olting.

I have referred to the driving-cable as being placed above the track centrally therewith; but it may, if desired, be placed at one side of the track, as shown in Fig. 21, in which case it will act also as a substitute for one of the guard-rails, and the catch will extend from the side of the carrier and the finger 8 will project upward. In this case the elevator is constructed as already described, eX- cept that the pocket is placed at an angle on a horizontal platform and is thrown out laterally, the longer section consisting of part of the guardrail instead of part of the lower rail, as shown in Fig. 22. The pocket 70 is fixed on the platform of the elevator-carriage K and an arm 74 on the shaft 73 contacts with an inclined rod 78, supported from the track, so that the finger 76 is swung inward as the elevator-carriage reaches its upper position. It will be seen that the pocket of the carriage is brought in such position that the carrier will move instantly therefrom onto the track the moment it engages with the cable, so that it is only necessary to elevate the carriage and deflect the hinged track-section fora moment in order to transfer the carrier, thus permitting the transfer to be eifected with little danger of collision with other carriers moving on the track.

The lifting of the elevator-carriage K is effected by the usual elevating-rope 80, Figs. 1 and 18, or in any other suitable manner.

When the ways extend past counters on dtferent lines at angles to each other, they must be provided with curves, as also in case it is necessary to convey the carriers from one level to another. 1

As the retention of the carriers with the ca ble throughout a tortuous course would be attended with considerable difficulties, I depend upon the momentum of the carriers to carry them round curves vertically and horizontally and at such points deflect the cable out of the lines of the tracks. Thus in Fig. 3 the arrangement of curves connecting the horizontal and vertical parts of the tracks is shown. The portion of the cable co-operatin g with the outer curve I is supported by a guide-pulley 81, so arranged that the cable will bein proper position as respects each straight portion of the track, but will be wholly outside of the curve. If the carriers are provided with catches or grippers for positively pinching the cablesuch, for instance, as are shown in Letters Patent No. 3let,339-the catch releasing and engaging devices are arranged to operate on said catches just before and after passing the curve; but the construction of catches hereinabove described renders this unnecessary, as it engages frictionally with the cable and permits the cable to leave and enter the catch without any movement of the latter of the necessary use of catch-operating appliances. The inner curve I has a longer IIO radius than the curve I, leaving space between the two curves for the insertion of one, two, or more guide-wheels 82 82, two being shown, which deflect the inner portion of the cable from adjacent to the line of the'track at the curve. The curve I of the outer or upper track when the Vertical part of the latter joinsthe lower horizontal track portion, Fig. 3, is a regular curve, while the curve I of the other track is swelled outward to increase the space between the two, the said curve I having its center beyond that of the curve 1 the cable being guided by guide-wheels 83 84. With each curved and vertical portion of the track are combined two parallel guide-rails 85, so arranged as to prevent the carriers from leaving the track at such curved and vertical portions.

Where the curve connects two parts of the track at an angle to each otherupon the same vertical plane as does the curve I Fig. 2, the cable is deflected to one side by aguide-wheel 87. At the end of the track the cable passes round guide-p ulleys 88 89 to the driving-wheel of an engine, by which the requisite traveling motion is imparted.

By the arrangement of cable and curves above described the carriers are conducted in positive connection with the cable to the beginning of each curve, then are automatically disconnected from the cable, either by reason of deflecting the track from the cable, as before described, or by means of a contact-piece of sufiicient extent to engage all the contactfingers of the carriers to move the cable-catch from engagement with the cable and pass the curve by momentum, and then automatically connect with the cable again to be positively driven until another curve is reached.

In most instances I prefer to set the ad j acent guide-pulleys 82 84: so that the carriers shall descend the vertical part of the track without connection with the cable. Thus the carriers will travel more rapidly during its descentthanif connected to thecable. To permit the carriers to be controlled in their descent or thrown out of connection with the cable I support the pulleys 82 84 on adjustable sup ports, so that the cable can be set near or away from the track. Thus the wheels are supported by brackets 90, secured adjustably on arms 91, extending from the adjacent yoke D", that supports the track and guard-rods.

At the cashiers desk the cable passes round a guide-pulley 49 and the upper track is deflected downward, and guard-rails92 are arranged to guide the carrier as it is placed by hand upon the track and passed up the incline until the catch engages with the cable. The receiving end of the lower track is also deflected downward and also laterally, as shown in Fig. 4, so as to carry the incoming carriers away from the cable to a position to be readilytaken from the track by the cashier.

As the cable when moving rapidly is apt sometimes to acquire a rapid vibration resulting in a humming noise, or sometimes becoming so extended as to move at points out of the line of carriers, I provide bearin gs 93 (see Fig. at intervals, which will contact with the cable andlirnit its vibration. Asshown, said bearings are elongated blocks centrally suspended loosely from the ends of supporting-arms 95, said arms being somewhat elastic, to yield and break up the vibration of the cable.
