PARCEL-CARRYING APPARATUS FOR STORES.

SPECIFICATION forming part of Letters Patent No. 301,121, dated July l, 1884i.

Application filed May 2, 1884. (No model.)

To @ZZ whom it may concern:

Be it known that I, HARRIS H. HAYDEN, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Parcel-Carrier Apparatus for Stores, of which the following is a specification.

My invention relates to that class of storeservice apparatus in which the carriers must 4be raised to elevated tracks and properly 5o jections c.

placed thereon; and my invention consists in certain elevating means, fully described hereinafter, whereby the carriers may be raised and put in place without the slightest danger of being prematurely discharged from their position upon the elevator.

My invention further consists in improved means for arresting the carriers at their stations, and in an improved mode of constructing the track and connecting it to its supports.

In the drawings, Figure l is a perspective view showing part of atraek and elevating apparatus. Fig. 2' is a back view of the elevator. Fig. 3 is an enlarged side View of part of the apparatus. Fig. 4 isa plan of Fig. 8. Fig. 5 is a view showing the stop devices. Fig. 6 is a sectional view showing the manner of making and securing the track. Fig. 7 is a eross-section of the track with a carrier thereon, looking in the direction of the arrow, FigA 5.

The way consists of stiff wires or rods a and inclosing sleeves or tubes b, of niet-al, paper, wood, or other hard and rigid material, and the supports for the way are brackets or yokes A, of any suitable shape, each of which has a cylindrical projection, c, corresponding in diameter to that of the tube b, and perforated for the passage of the rod a. In puttingthese parts together the rod c is passed through the projection c, and the sleeves b are brought to abut against the ends of said projection, thereby securing a practically continuous track of uniform diameter, as well as a strong and durable connection between the supporti n g-bracket and the track. In order to secure greater rigidity, the rods a may be threaded at the ends and screwed into threaded sockets in the pro- (See dotted lines, Fig. 6.) This kind of track may be used whether the way is to be single or double. In the latter case a yoke-like support, A, such as illustrated in the drawings, is employed, the projections c being at the lower separated ends, and the rods a extending through the projections,so as to break joints within the sleeves at some distance from the yokes. The yokes are provided with perforated lugs or offsets, through which extends the supporting-rod B, and the whole structure is suspended from the ceiling or is otherwise suitably supported, either in an inclined or horizontal position, according to the method of driving the carriers.

In the construction illustrated in the drawings each carrier D is provided with a frame, in which turn two wheels, E, with centra-l flanges, e, so as to afford side treads which restv upon the parallel rails of the track, a pendent stem, d, of the frame extending downward between the rails, and being connected to or supporting a basket or receptacle, F. To place these receptacles upon the track it is necessary to divide the receiving-rail to form a passage, x, through which the stems d can be introduced into the space between the rails, as shown in my Patent No. 272,686. To lift the carriers and to automatically place them upon the tracks when the latter are at too great a height to permit this operation to be performed by hand, I make use of an elevating apparatus, one forni of which is shown in the drawings, and will now be described. In the said apparatus there is a fixed guide, G, and a frame, H, which slides vertically upon said guide, the former being suspended from the ceiling or otherwise secured in a vertical position, and consisting in the present instance of a rod carrying at the lower end a crossplate, I, through which slide the parallel rods f f of the frame II, consisting of said rods, a cross-bar, J, and a crossplate, K, from the latter of which extend two arms, g g. A pulley, j, is carried by a bracket, L, secured adjustably to the rod G, and a cord, W, passes over this pulley and is connected to the frame H, which may thus be elevated until a pin, k, at the side of the cross-bar K engages with the shoulder of an L-shaped catch, M, pivoted to the cross-bar I, when the frame H will be locked in its elevated position. By pulling upon a cord, w', the catch is swung to re- IOO lease the frame H, which then descends by its weight, guided by the rod G, a spring, S, between the plates I J reducing the shock as the motion of the frame is arrested, and a shoe, Z, upon an arm of the catch M being brought against one of the rodsf, so as to create africtional resistance to the descent of the frame proportioned to the strength of the pull upon the cord fw', or friction-rollers w2 may be setl on the rod G by means of a collar and arranged to inclose the cord w', and `jointedly hung to the collar, so as to permit the cord to run freely when the elevator is going up, but to pinch it when it drops, and thusprevent thc elevator from dropping too suddenly.

Upon pivots or journals p, one extending outwardly from the end of each arm g, swings a U-shaped frame, N the outer ends of the limbs of which are bent downward, as shown, the parts all being arranged so that when the frame II is brought to the limit of its upward movement the bent ends ot` the frame N will make contact with wings n, projecting at an an angle from the track at opposite sides of the passage x, the frame being thereby tilted to the position shown in Fig. 3, the tilting nio tion being limited by lugs tt on the ends of the arms g g. v

To the plate K is pivoted a latch, l?, the outer end of which projects slightly beyond the plate, while the inner end is beveled, and has a notch, y, adapted to receive the stem d Y l ofthe carrier when thelatter is passed between the arms g, a spring, u, tending to throw the catch in the direction of its arrow, so that the carrier is held securely, with its stem in the notchand with its wheels resting upon the bars q of the frame N, and cannot be detached by any jolting or agitation of the elevatorframe. i l

Upon the plate I is a stop consisting of a plate, R, having an inclined edge, with which the outer end ofthe catch Pis brought in contact as the end of the frame N is brought against the wings n. The said' inclined edge swings back the catch as the frame II reaches its upper position, so that the stem d escapes from the notch y, and the carrier will slideby gravity down the inclined frame N to its position lupon the track, the stem d passing through the space x, when, if the track is inclined, the carrier will move by force of gravity to the desk. The catch M and plate R are relatively so arranged that the said catch will engage with the pin k and lock the frame in its elevated position before the latch P is thrown back, so that it would be impossible for the carrier to be discharged until all the parts are in position to direct it properly onto the track.

To prevent the swinging of the track or of the elevator from carrying the parts from their proper relative positions, arms or braces T are extended from the plate I or other fixed parts ofthe structure to the adjacent yokes A.

By means of the elevator thus constructed,

use of a tilting frame, N, as other catches or detents may be employed with like effect,

while the frame N may in some instances be secured in a fixed position upon the elevator.

It has been found difficult in this class of apparatus, where the carriers are sometimes heavily laden, to arrest them suddenly without destructive effect either upon the carriers or the track, the arresting devices being generally of such a character as to wedge the carriers against the track, or cause them to rebound by the resistance of a spring-buffer or fixed stop. To overcome these objections I employ arresting devices so constructed as toy lift the carriers from the track, thereby arresting them suddenly without the shock that would otherwise result.

One form of elevating-stop is illustrated in Fig. 5, and consists of parallel inclined iingers U, each supportedv below one of the rails of the track in such a position that a cross piece or bar, V, on some part of the carrier will be carried by the momentum of the carrier against and slide up upon the fingers until the wheels E of the carrier are free from contact with the track. Such lifting -stops may of course be arranged at the sides of the track or above the same in any position; but they are preferably placed beneath the track, as their contact withthe carrier is then more certain should the carrier swing to one side from its usual vertical position. Y

It will of course be apparent that the relative lengths or positions of the stops U and cross-pieces V on different carriers will be graduated so that carriers may pass all stops except those at. the stations where they are to be arrested. l

In order to aid in arresting the carrier without a shock, and also to arrest the rotation of the wheels when the same are elevated from the track, a strip or plate, WV, preferably of spring metal, is suspended beneath the connecting-rod B in such position that the wheels may make contact with this strip as thecarrier is lifted. v

Io insure contact of each carrier with its stop, even when the carrier is oscillating, I curve the cross-piece V, with which the ngers U U engage, so that it will coincide with the same circle as that in which the carrier swings on the track, as shown in Fig. 7.
