Each jaw M, as shown in Fig. 8, has an is supported from above by suitable hangers arm 0 extending upward and outward from its pivotal support at b. The upper ends of the two arms of each set are connected by two links P P, pivoted together at their inner ends at c to form a toggle. The two plates N N, to which the jaws M are pivoted, are provided with vertical slots Q,.and a rod R, extending through the slots connects, the central joints depressed, the upper ends of the jaw-arms 0 pulled toward each other, and the jaws M thrown open, as seen in Fig. 10, thereby releasing the cable.

Pivoted between the plates N N at d is a bell-crank plate T, having one arm slotted and the other forming a finger T, extending laterally between the two sets of jaws M, as shown. A link U, whose lower end carries a pin confined in the slot in the plate T, connects the latter with the swinging frame K, so that when the frame is depressed the finger T is also depressed to permit the cable to drop from between the jaws M, as seen in Fig. 10. When the frame K is released and again lifted by its spring L, the finger T picks up the cable and lifts it up between the jaws, and the latter close upon it under the pressure of the spring L, exerted through the frame K, link Q, and toggles P P, and grip the carrier to the cable again.

Owing to the nearly Vertical position of the slot in the plate T, the latter is only slightly rocked on its pivot as the frame K and link U are depressed until the pin in the lower end of the link U reaches the bottom of the slot, whereupon thefurther depression of the frame and link quickly rocks the plate to its full limit of play and throws down the finger T to the position shown in Fig. 10. So when the frame is released and lifted by its spring the first upward motion of the finger T is quick, so that it carries the cable up between the jaws M before the latter have a chance to close. To this end also the upper end of the link S, which operates the jaws from the frame K, is connected to the latter by aslot-and-pin connection, so that as the frame is depressed it does not act on the link and jaws until the pin on the frame reaches the lower end of the slot in the link. After the frame has been completely depressed and is released the jaws do not begin to close until the pin has moved to the upper end of the slot, and during this time the quick upward movement of the finger T takes place, so that the latter has reached the position shown in Fig. 11 and lifted the cable upbetween the jaws before the latter begin to close.

To insure the disengagement of the cable from the jaws when the latter are opened by the depression of the frame K, the plate T has a projection T substantially at right angles to the finger T, which projection as the finger is depressed strikes the upper side of the cable and forces it from between the jaws. The outer jaw M of each set has secured to it a small curved plate V, Figs. 7 and 8, which overlaps the face of the other jaw of the set. This plate V arrests the cable as it is lifted by the finger T and prevents it being carried above the gripping-faces 0f the jaws.

WVhile I have illustrated and described the pivoted spring-jaws M and cable-lifting finger T as combined and co-operating with each other, yet each of them separately forms a novel feature of my invention. Thus the spring-jaws might be so shaped as to constantly straddle the cable, both when open and closed, so that the lifting-finger would be unnecessary. Again,the lifting-finger might be employed to advantage in combination with stationary jaws formed simply of a slotted plate-such, for instance, as that shown in Fig. 12. By the employment of two such plates with the lifting-finger between them and a strong spring applied to the frame K the finger could be made to press the cable so tightly into the slots and between the plates as to firmly grip the cable, while the projection T on the plate T would insure the disengagement of the cable from the jaws when the frame K was depressed. Again, inasmuch as the only office of the swinging frame K is to operate the grip-jaws and cable-lifting finger through the medium of the links S and U, attached to the cross-piece of the frame, it is evident that a vertically-reciproeating frame or cross-piece, suitably supported in guides on the carrier-frame and held up by springs might be substituted for the pivoted frame and'the links S and U be connected to it in the same manner as to the swinging frame.

Having described above w the carrier is released from the cable by the depression of the frame K and regripped to it by the resetting of the frame, I will now explain how the frame is depressed in the use of the car riers in my improved apparatus to automatically release the carrier from the cable when it reaches the central station or the side track of its own station, and how it is automatically regripped to the cable as it is pushed on past the central station orfout ontothe main trackfrom its own side track.

The automatic switch by which each carrier is directed from the main track to the side track of its own proper station is best illustrated in Fig. 2. At the entrance to each side track the main track is cut in two and provided with a hinged section WV, which can swing laterally into line with the side track E and back into line with the main track. In Fig. 2 this hinged section of the main track is shown as composed of the two track-rails secured at their opposite ends to the lower open sides of rectangular brackets B E the two brackets being connected at their tops by a brace-rod B The bracket B is hinged to a bracket B, supporting the end of the main track, by a hinge at e. The bracket B is curved to conform to the arc of the circle in which it moves, and the adjacent face of the bracket B conforms to the same curve. Carried on studs on the top of the bracket B are two rollers f f, which extend over and rest on the top of the bracket B, the latter forming the support for this end of the track-section. A curved guide-wire W extends beneath the brackets B and B in the direction shown and is secured at its opposite ends to pendent supports on the under sides of the tops of the brackets 13 B. Each carrier has on it one, or preferably two, upwardly-extending pins or projections 00, Figs. 6 and 7. These pins are of different lengths on different carriers and arranged in such relative positions on the different carriers that the pins on each carrier will engage the guide-wire TV at the station to which the carrier belongs, but will clear all the others. Thus when a carrier belonging to the station represented by Fig. 2 reaches the swinging track-section WV its pins as x will engage the right-hand side of the wire V, and as the carrier is gripped to the cable and is carried along by it the pin 00 is forced along the side of the wire WV. As the carrier is held to the track by the rollers I, it pulls the swinging section into line with the side track E and the carrier passes onto the side track. As soon as the carrier leaves the swinging track-section a weight g on the end of a cord h, carried over a 'pulley'i on the bracket B and secured to the bracket B (or a suitably applied spring instead of the weight,) returns the swinging section to normal position in line with the main track, so

.that carriers belonging to other stations which may follow can pass by unobstructed. As the side-tracked carrier reaches the side track E two laterally-projecting pins to ac on its swinging frame K ride under two wires Y Y, one above and just outside of each of the track-rails, which depresses the frame K, thus releasing the cable in the manner heretofore explained, and the latter, which has been pulled from its course under the main track by the carrier, returns to its normal position, while the carrier, owing to the friction of the pins m 00' against the wires Y Y under the tension of the spring L,is arrested at the station. YVhen it is desired to send the carrier to the central station, it is simply pushed on out the opposite end of the side track onto the main track, a pivoted switch 3 forming the necessary track connection, and returning to normal position under pressure of any suitable spring when the carrier has passed to the main track. Just as the carrier reaches the main track and the open grip has passed into line with the cable, with the finger T immediately below it, as seen in Fig. 10,'the

pins as m on the frame K pass from under the ends of the wires Y Y, the frame is reset by its spring L, the finger T lifts the cable up between the jaws M, and the carrier is automatically regripped to the cable and carried on by it to the central station 0.

The only devices employed at the central station 0 for releasing the carriers from the cable and arresting them are two wires 1 31 parallel with the track and arranged in the same relative position thereto as the wires Y Y to the side track. The pins as x on the frame K ride under these wires y 1 and depress the frame, thereby releasing the cable, while thercarrier is arrested by the friction of the pins 00 m on the wires. When the package has been wrapped and replaced in the carrier, the latter is simply pushed onto the right, and as the pins x 00 pass from under the ends of the wires 3 11 and release the frame K the finger T picks up the cable again and lifts it between the jaws M, which close upon it, and the carrier travels on to its proper station. It will thus be seen that all the carriers are released from the cable and arrested at the central station, but at each side track only such of thenf as belong to that particular station.

The basket-supporting frame is composed of the rectangular top plate H, Figs. 6 and 7, by which it is secured to the arms G, depend ing from the carrier, and four pendent rods Z, one at each corner of the plate H. The opposite rods at each end of the plate are joined by a cross-rod at their lower ends, or the three rods may be bent from a single piece of heavy wire. The basket Z is rectangular in shape and preferably composed of wire. It surrounds the bottom and sides of the supporting-frame, but is mounted on the latter at its top by sleeves j, encircling the rods Z at each corner of the basket. In the bottom of the basket is an oscillating plate A, having a thumb-piece extending through the bottom. To this oscillating plate are secured two latch-rods A extending to the ends of the basket and projecting over the cross-rods of the supporting-frame. When the plate A is oscillated by the thumb-piece and the latchrods withdrawn from engagement with the cross-rods of the supporting-frame, the basket may be lowered on the rods Z until the sleeves jrest on the cross-rods at their lower ends. This gives more easy access to the basket. When the carrier is ready to be sent out on the track, the basket can be pushed up and latched in the position shown in the drawings. I prefer to construct the basket with its top closed and formed of the plate K, and with the upper half of one of its sides open, as shown,though it may be madein any other suitable manner.

I am aware that automatic switches operated by the carriers are old in store-service apparatus, and do not claim the same, broadly, as my invention; but I believe I am the first to combine a main track and side track of any sort with a laterally-movable section of the main track and a guide which is engaged by the carrier while traveling in the line of the main track and causes the latter to pull the main-track section into line with the side track, so as to automatically switch the carrier onto the side-track, and my invention contemplates, broadly, the combination of those elements operating in the manner described, regardless of the particular form and arrangement of them. I am also aware that carriers in such apparatus have been provided with grips, which were released automatically by trips located adjacent to the track; also, that it has been proposed to automatically regrip the carrier to the cable by means of devices located adjacent to the track and acting on the jaws of the grip; but I believe the gripping mechanism which I employ for the purpose of automatically releasing the carrier from the cable and automatically regripping it thereto is broadly new, both in construction and mode of operation.

Having thus fully described my invention, I claim- 1.
