STORE-SERVICE APPARATUS.

SPECIFICATION forming part of Letters Patent No. 413,991, dated October 29, 1889.

Application filed May 1'7I 1889. Serial No. 311,202. (No model.)

To @ZZ whom t mayconccrn.:

Be it known that I, THOMAS WILSON, J r., of Menands, town of W'atervliet, county of Albany, and State of New York,` have invented a new and useful Improvement in Store-Serv ice Apparatus, of which the following is a specification. t

My invention relates to a store-service apparatus in which a car or carrier is mounted on a single wire constituting a track therefor, said wire being secured at its ends to vertically movable supports, by means of which the wire track can be inclined in either direction, the carrier being moved by gravity when the wire track is so inclined.

My invention lies in the improvements hereinafter described; and it consists of the combination of devices hereinafter specied, and especially pointed out in the claims.

Accompanying this specication and forming a part of it is one plate of drawings, containing five (5) figures, illustrating myinvention, in all of which similar letters refer to corresponding parts.

Figure l is aview in elevation showing my improved apparatus arranged for operation, the respective inclinations of the wire track being shown in differently-arranged dotted lines. Fig. 2 shows the device at one end of my apparatus enlarged, with part of the tubular support therefor broken away to show details of construction, the carrier being engaged with the catch. The tube is also broken at about its middle transversely to allow for indefinite length. The arrows indicate the direction of motion of the operating parts. Fig. 3 is a horizontal section taken on the line l l of Fig. 2. Fig. 4 shows a portion of the tube, looking from the direction of the wire. Fig. 5 shows the metallic strip or shoe at the bottom of the tube.

Fig. 1 illustrates a complete apparatus; but for the purpose of elucidation a description of the construction ofthe devices at one end of the apparatus with its component parts will suffice, as the two ends are similarly constructed.

A is a tube dependent from and fastened to the ceiling X. The wire track R, on which moves the carrier B, having the receptacle C, terminates in the spring K, which spring is attached at its other end to the pin P, which in turn is fastened to the yoke Y. The ends of this yoke expand into the arms Y Y2, the wheels W 72 being adjusted between the same and pivoted thereto, said wheels being grooved to fit the curve of A vertically. (See Figs. 2 and 3.) The bow of the yoke is provided with the lug y, to which is fastened the line E. This line, moving in the direction of arrow 1, passes up and over the wheel W, which is pivoted in the tube A at its top, and is carried down through the curved tubular guide M, which is joined to the tube A by the arm m, and serves to hold the line free of the yoke and the wheels lV VZ.

At the bottom of the tube A is the shoe D, fastened to the cap A', covering the free end ot the tube by the screw N. The shoeis composed, preferably, of a single strip of dat steel formed with the claw d2 at one end, and

having the other end bent upward and forward and then turned sharply back on itself to form the catch d. The tube A is slotted vertically and oppositely at T T, as well as above where the wheel W is accommodated, and is provided with the spring S,which rests upon the inner face of the cap A', and eX- tends up and a little above the lower end of the slots T T, and with the spring S', which depends from the pin or fastening s and eX tends a little below the upper ends of T T. The pin I), to which the spring K, terminating the wire track R, is fastened, and which in turn is fastened to the yoke Y, passes through the bow of the yoke and through the oppositelyrplaced slots T T, resting on the spring S, and projects just beyond the circumference of the tube A and between the arms Y Y2. (See Fig. 3.)

The car or carrier B is composed of two corresponding plates placed opposite one another and solidly joined at l), b', and b2, and the wheels V V, adapted to revolve between the two plates pivoted thereto and grooved to lit the wire track R. At b3 b3 there are openings between said plates on a line with the grooves in the wheels V V, through which the wire track R. and spring K pass, serving thereby to steady the carrier and car when in transit. The receptacle O depends from the carrier B by the arms c c, of which there IOO `in the slotted guides T. T.

are four, two on either side of B, and running to opposite sides of O.

In operating my apparatus it should be borne in mind that each dependent tube with its appurtenances constitutes a station. In order to transmit the carrier B and its dependent receptacle C from one station, the handle e2 of the line E is drawn in the direction indicated by arrow 2. This causes the yoke Y and the attached pin P, carrying the spring K and Wire R, to move vertically in the direction of arrow 1, the said pinmoving This movement continues until the pin P has reached, iirst, the spring S and then, compressing that, the top of the slots, and is arrested by the solid tube. The line E is provided with a button e, so adjusted with reference to its position on the line that when the pin P. reaches the top of the slots e shall be' just below D. Then, if it is desired to retain the yoke and its att-achments in the elevated position, the line E is slipped into the claw d2, and the button e', resting against the bottom of D, holds it stationary. The position thus attained is shown by the dotted lines in Fig. l. The act of raising the yoke and attached wire track R has disengaged the carrier at bfrom the catch d', and the carrier and car are at once free to move along R with the impetus which their weight and the inclination of the Wire track give to them. The spring K allows for the increased tension of R in moving to theposition indicated by the dotted lines. lAs has been said, slipping the line E into the claw d2 and the button e under D holds the yoke and Wire lin their elevated position. If it is desired to return them to their normal position, (indicated b`y the continuous black lines, Fig. 1,) a slight additional pull of e2 in the direction of arrow 2 enables e to be released, and at the same time compresses S to an extent that when the hold on the handle is loosened the recoil of S and the weight of Y and its accompanying parts send the yoke, pin, and attached wire back to the bottom of the slots, Where the pin P first strikes upon S, which acts as a cushion or buffer. The carrier and car moving on the inclined wire in the direction indicated by arrow 3 reach the other station, constructed precisely as the station they have just lett, where the end b of the carrier is caught andA retained by the catch d', formed at the end of the shoe D. To return the carrier and car to the first station the same movements are made use of vas have already been described, giving a position and incline' indicated by the dotted and broken line R2.

I am aware that tracks have been heretofore constructed in which either end can be raised by vertically-movable end supports, so as to form an incline; hence I do not claim, broadly, a track adapted to be so manipulated.

Having thus described my invention, what I seek to secure by Letters Patent is- 1. In a store-service apparatus, the combination of the vertically depending tube formed with oppositely arranged vertical guide-slots, a sliding yoke arranged on the tube, friction-rollers journaled in the yoke to bear on the face of the tube, a track-supporting pin arranged in the sliding yoke and through the slots of the tube, and mechanism for lifting the sliding yoke and track-supporting pin,.substantia11y as described.

2. In a store-servicel apparatus, the combination of a vertically-depending tube formed with oppositely-arran ged vertical slots, a sliding yoke arranged on the tube, provided with friction-wheels to bear against the face of the tube, a track supporting pin extending through the sliding yoke and through the slots of the tube, mechanism to lift the sliding yoke and track-support, and elastic cushions interiorly arranged in the top and bottom ofthe tube to contact the track-supporting pin, substantially as and for the purpose speciied.

3. In a store-service apparatus, the combination of the vertically-depending tube havthrough the slots of the tube, a wire track,

and an extensible spring-connection supporting the end of the track and fixed to the end of the track-holding pin, substantially as and for the purpose specified.

4. In a storte-Service apparatus, av dependent oppositely-slotted tube, such as described, combined with avertically-movable yoke and a mechanism for producing such movements, and provided with they shoe D, formed with theY catch d and the claw d2, as hereinbefore described and set forth.

In witness whereof I have hereunto set my hand this 14th day of May, in the year of our Lord 1889.
