OLIVER I. EATON, OF NEW YORK, N. Y.

ENDLESS PACKAGE CARRIER OR ELEVATOR.

SPECIFICATION forming part of Letters Patent No. 252,931, dated January 31, 18(2.

(N0 model.)

To all whom it may concern:

Be it known that I, OLIVER N. EATON, 0 the city of New York,in the county and State of New York, have invented a new and useful Endless Package Carrier or Elevator, of which the following is a specification.

The object of my invention is to provide suitable means for taking packages, bales. barrels, boxes, &c., from the holds of vessels or similar situations, continuously carrying them to their destination on the wharf or into the warehouse, and depositing them at such destination without dumping or otherwise disturbing their equilibrium or their contents during transit. To this purpose 1 have adapted parallel endless chains or ropes travt-ling on put leys or guides suitably located, as hereinafter set forth, and carrying suspended between them one or more cradles capable of taking up, carrying, and setting down a load in the manner and with the construction hereinafter set forth at length. Sin-h devices enable me to unload a vessel and deposit the load at its destination in a continuous delivery, thnslosing no time in idle intervals, and without any disturbance or injury resulting from handling. The apparatus is adjustable to the varying circumstances of vessel, wharf, storage warehouse, 850.

My apparatus and devices for accomplishing these objects are illustrated in the accompanying drawings, in which- Figure 1 is a vertical section of the entire apparatus. Fig. 2 is a front and Fig. 3 is a back elcvatioin aud Fig. 4 is an enlarged per-.

spective view of the carrying-cradle and its mode of operation.

Similarlettersindicatesimilarparts throughout the several views.

A is the wharf, and B the vessel.

K K are standards to be placed in the hold of the vessel or a similar situation, and bearing thepulleys O U and D D.

L L are companion standards bearing the pulleys F F and acting to brace the standards K K, and thus form a rigid framework. These latter standards rest against the sides of the hatchway or any convenient place of attachment on the vessels deck, and are respectively pivoted orjointed to the standards K K at It R, whereby the two sets of standards become adjustable, and may be lengthened or shortened by changing the relative location of thejoint or pivot.

M M is a suitable frame work bearing the pulleys E E, which are fitted with teeth or sprockets to engage and drive the endless chains or ropes O O in thedirectiou indicated by the arrows in Fig. 1,-and bearing also the motive gearing H H and G G. Power may be applied in the ordinary ways to either the upper or lower gearwheels. This framework maybe made movable by means of wheels, to accommodate. any movement of the vessel or to facilitate removal or adjustment. Connecting these frame-works orstrnctures in the vessel and on the wharf is anotherframe-work, I I, composed of parallel sides, and made extensible to suit the varying distances between the two end frames. This last frame-work is also pivotedat R R and S S. and may therefore be raised or lowered at either end-as,for instance, into the position indicated by the dotted lines in Fig. 1. This framework has bars Q Q, which bear suitable guides, J J, to support the carrying-cradles and relieve the strain or tens on of the endless chains orropes. These bars Q Q may be extended above to support an awning or covering to protect the goods during transit, or the whole structure may he inclosed for the purposes of complete pr0tection. Friction and wear are prevented by rollers or frictionwheels, placed either in the guides or on the trunnions of the cradles. \Vhen these wheels are placed on the trunnions of the cradles they may be so located as to pass between and on the inside of the pulleys,and the guides may be brought out to accommodate them, as shown most clearly in Figs. 2 and 3. In this way the necessity of grooving the face of the pulleys to accommodate these wheels may be avoided. Upon the pulleys thus 10- cated the parallel endless chains or ropes O O ing to the judgment of the mechanic. It consists of two sides, here sector-like and open, having at their angular and upper extremities trunnions T T, adapted to bear in the chains or ropes and suspend like a pendulum the cradle and its load,and having at and connecting its opposite and lower extremities a bar, U, having laterallyprojeeting fingers or teeth V V, suited to bear a load, and yet allow the passage between of corresponding sets of fingers or teeth, W W, stationary at the points of removal and deposit.

The cradle N in Fig. l is shown in the act of taking up a load for transportation from the stationary platform Y at the point of removal, and the cradle N is shown in the same figure as just depositing the load at its destination onthestationary platform orslide P,atthcpoint of deposit.

The frame-work MM may be situated on the wharfor 011 any story of the storage-warehouse and the apparatus adjusted as indicated.

The manner of use and operation of this carrier or elevator is as follows: A package or bale,.or more than one, constituting the load to be transported, is placed upon the slide X in the hold of the vessel, and slides down onto the platform Y across the intervening space, which is very small and only sufiicient to permit the passage of the finger-bar of the cradle; or the load may be deposited directly on the platform Y. There it rests upon the fingers composing the platform until the arrival of a cradle, whose fingers, passing up between the fingers of the platform, take up and carry the load until the second platform, P, at the point of deposit or destination, is reached, whereon the load is left or deposited as the fingers of the cradle pass down between the fingers of this second platform. From this second platform the load may be removed by hand; or the platform may be declined, as shown in Fig.

whereupon the load will slide down out of the way to its place. Throughout its journey each cradle is self-righting or automatically adj ustable to the perpendicular, so that, the load maintains its equilibrium throughout transportation. This obviates the possibility of injury or disturbance to the load during transit. The load is also taken up and deposited without any jar or dumping, and this is another element of safety to the load. This operation is repeated, and the removal, carriage, and delivery become more or less continuous, according to the number of cradles and the rapidity of revolution.

The vessel may be loaded from the wharf or warehouse by reversing the direction of revolution, and the operation of the apparatus would be the same as in the opposite direction.

Vhat I claim as my invention, and desire to secure by Letters Patent, is-

1. An endless traveling carrier or elevator, preferably portable and adjustable, composed of parallel endless chains or ropes, traveling upon properly located pulleys and bearing suspended between such chains or ropes, one or more carriers or cradles adapted to take up, carry,.and deposit loads.

2. -A movable carrying cradle self-adjusting to the perpendicular and having two sides,with means of suspension at their tops, and at and between their bottoms a connecting-bar, from which project laterally teeth or fingers suited to support a load and to'permit the passage between of corresponding stationary sets of teeth or fingers in the taking up and depositing of the loads.

3. A method of removing and transporting
