THOMAS SPENCER MILLER, OF SOUTH ORANGE, NEl V JERSEY.

HOlSTlNG AND CONVEYING APPARATUS SPECIFICATION forming part of Letters Patent No. 777,122, dated December 13, 1904, Application filed February 29, 1904. Serial No. 195,756. (No model.)

To (ti/Z whom itmag concern:

Be it known that I, THOMAS SrnNcnR MIL- LER, a citizen of the United States, and a resident of South Orange, county of Essex, and State of New Jersey, have invented a new and useful Hoisting and Conveying Apparatus, of which the following is a specification.

My present invention is particularly applicable to the transportation of loads between different points within a quadrilateral, although various features of it are susceptible of other useful applications.

In the accompanying drawing-s1 have shown the invention as applied to the unloading of lumber from a ship.

Figure 1 is a perspective view. Fig. 2 is a plan view. Fig. 8 is a side view. Fig. 1 is a cross-sectional view, and Figs. 5, 6, 7, 8, and 9 are details.

A is the ship. B is the dock alongside. C is a load of lumber. a a o are hatchways through the deck. 7) b are masts of extraordinary height, between the tops of which is stretched the cable 0. (Z (Z are booms 0x tending from the masts outboard over the deck. a is a cable stretched between the ends of said booms. f f are two booms extending in the opposite direction from the masts and between the ends of which is stretched the cable The quadrilateral formed by the booms (Z (Z f f and the cables 0 9 includes within its field the hatchways and deck and a portion of the dock, or, in other words, the surface from various parts of which the loads are to be taken and the surface to which the loads are to be delivered. High overhead this quadrilateral is longitudinally crossed by the cable a.

H, l, and J are three trolleys or carriages running, respectively, on the cables 0, e, and

Each of these trolleys or carriages is constructed similar to the trolley H, (shown in Fig. 9,) consisting of a frame it, in which is journaled the wheel if, running on the cable 0.

The load (1 is suspended from trolley H by sheave-block it, hoisting-rope 1, bridle 2, spreader 3, and slings 1 4, which slings are long enough to extend from the deck down to the bottom of the hold.

K is a swinger-guide suspended from trolley H by rope 5 and bridle 6. It engages the slings 4: at, so that they slide up and down through it. It is bridled to the swinger-ropes 7 8, which extend, respectively, through the.

sheave-blocks 1." and j of the trolleys I and J.

The load when hoisted above deck may thus be swung between the cables 0 and g, and the plane in which it swings may be located at any point between the masts by the movement of the trolleys II, I, and J. In this way successive loads may be taken from different parts of the deck or from different hatchways and transferred to the same or different parts of the dock, or vice versa. The principle thus accomplished is exceedingly important, since it enables the preparation or collection of loads to be going on simultaneously at differ ent points of the quadrilateral field of operations, which leads are taken successively by the apparatus, which therefore does not have to wait on the preparation of the loads.

I will next describe the means for moving the trolleys and operating the hoisting and swinging ropes. The trolleys are provided with the traction-ropes 9 10 11, which extend parallel with the cables and then parallel with the mast and booms to a common traction-actuator l), (shown in Fig. 6,) and located convenient to the mast Z). This actuator prefer ably consists of the three-part drum 12, controlled by a friction -bral e 13 and frictioncluteh 1 1. The trolleys are moved in one direction by inhauling ropes 9 l0 l1 and paying out ropes 1, 7, and 8 at the same time. Reversing the operation causes the trolleys to move in opposite direction.

The hoisting-rope 1 extends from the trolley H parallel with the cable 0 and thence down the mast b to the hoist-actuator E,which preferably consists of the drum 15, operated. by a reversible link-motion engine. (Diagrammatically shown in Fig.

The swinger-ropes 7 8 extend from the trolleys I and J parallel with the cables c and 7 and then parallel with thebooms (Z and f to the swinger-actuator F, which preferably consists of the two drums 16 1'7, controlled, respectively, by the friction-brakes18 19 and the slip friction-clutches 20 21, which are preferably constructed as described in my Patent No. 715,111, and which clutches are respectively controlled manually by the screws 22 and 23. This actuator is intended to run continuously in one direction, thus maintaining tension in both ropes all the time.

i The operation is as follows: Starting from the bottom of a hatchway the fall or slings 4t is hoisted through the swinger-guide K until the load is above the deck. The drums may then be operated to move the trolleys in unison to the desired point. Then the relative pressure of the slip friction- surfaces 20 and 21 is so adjusted that one overcomes the other suificiently to swing the swinger-guide in the direction desired and to the desired degree. Then the pressure of the friction- surfaces 20 and 21 is adjusted so as to hold the swingerblock in that position while the load is lowered and the hoisting-rope hoisted again, or the swinger-guide may be held in this position by applying the friction-brake to one of the drums 16 or 17. Thereafter the operation is reversed for swinging the swinger-guide to any position from which it is desired to take the next succeeding load. By skilful manipulation the hoisting or lowering operation may be going on at the same time with the swinging motion and the longitudinal motion, so that the pathway traversed by the load is a curved path way, being the minimum distance between the point of loading and unloading consistent with obstructions.

By controlling the swingerropes by the slip friction-surfaces shown those surfaces may be held in contact during all parts of the operation, so as to exert a continual tension on the ropes and enable them to be handled with greater precision. This tension might be supplied by other forms of mechanism.

By the arrangement that I have above described it will also be observed that the correct operation of the swinger-ropes is not interfered with by a lack of parallelism in the trackways'for the carriages I and J, such as the lack of parallelism resulting from the difference in distance between said traekways at the center and ends, respectively, necessarily incident to the employment of cables.

The booms (Z d ff are pivotally secured at their inner ends, so that when not in use they may be swung upward and secured against the masts. They are also made transposable, so that the longer and shorter booms, respectively, may be lowered on the opposite side of the mast, thus permitting the apparatus to be used for receiving or discharging the cargo on either side of the ship.

Various modifications might be made of the apparatus above described while still embodying features of my invention. Some of these may be mentioned, for example, as follows: One of the swinger-ropes, as 8, and all of the mechanism for supporting, guiding, and actuating it might be omitted, dependence being had upon gravity to produce the backward swing. The laterally-placed cables 0 and g, or either of them, might be for certain classes of work omitted, dependence being placed upon the tension of the ropes actuating the carriages I and J, for guiding their movement. The sheaves (Z (Z* 7f*, by which these ropes are guided, may be fixed in their lateral positions by other means than by attachment to the ends of the booms.

Having thus described my invention,I claim as new and desire to secure by Letters Patent- 1.
