COMBINED FLOATING CRANE AND ELEVATOR.

' SPECIFICATION forming part of Letters Patent No. 451,903, dated May 5, 1891.

Application filed December 10, 1890. Serial No. 374,196- (No model.)

To all whom, it may concern.-

Be it known that 1, JOHN E. lVALsH, a citizen of the United States, and a resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Combined Floating Cranes and Elevators, of which the following is a specification.

Myinvention relates to machines by means of which vessels are rapidly loaded and unloaded; and the improvement consists in the combination of two or more masts erected on board of a scow or vessel carrying two double cranes or slotted arms each on a verticallyadjustable sliding socket, to which they are connected, preferably, by universal joints. These arms again support either traveling trucks or elevator-legs, as may be required.

The improvement also consists in a mum ber of slotted beams mounted below the arms and carrying sheets of canvas or similar material, which, when spread over the hatches, will protect the workmen and the merchandise handled on both the vessel and the dock from the weather while discharging or loading.

In the accompanying drawings, Figure l is an elevation of an apparatus embodying these improvements placed between the vessels to be loaded and unloaded and in reach of a (lock. Fig. 2 is a plan view of Fig. 1 with the curtain removed. Fig. 3 is a side elevation and section through the dock, showing the protectingcanvas when spread. Figs. 4:, 5, and 6 are perspective views of details of the sliding sockets and their connecting-links for a derrick as used for unloading goods. Fig. 7 shows a sliding socket for a derrick carrying elevator-legs.

Similar letters of reference designate corresponding parts in all the figures.

Upon a scow or vessel S are mounted near its middle on opposite sides two upright poles A and B, preferably square, each having two grooves A A and B B extending from a point above the deck all the way up.

To the pole A is fitted the sleeve a, Figs. 1, 2, 3, and 4t, and held in position thereon by means of an upright shaft m, having screwthreads cutin its upper portion engaging with that cut in the opening a in the sleeve a. The shaft mis revolved by means of a crank m horizontal shaft m and gearing m, and permits the sleeve a to be raised or lowered on the pole A to any desired position.

Into two holes a a passing vertically through sleeve a, one at each side, are fitted the shanks of forks a". A peculiarly-shaped forging or casting a, carrying the rollers r r, is fitted to one end of an arm D and secured to a fork a by means of a pin 19 passing through both horizontally, thus allowing the arm D to be swung up by turningit around the pin 19 and at the same time to be swung sidewise, when it, together with fork a will turn in a hole a through which the shank of fork 0: passes, and is prevented from slipping back by means of a split pin 29 orsiinilar device.

The arms or booms D are extending horizontally from the pole A when in action, and in this position are supported by brace rods or chains connecting with the two ends of a collar or cross-cap A fitting around the vertical trunnion upon the upper part of the mast A. Theyare slotted throughout almost their entire length and carry each upon rollers and guided in the slot a traveling truck or trolley R, with a guide-roller r over which the hoisting-rope h passes before being dropped through an opening in the truck to the vessel or dock, while in the opposite direction it passes back over the roller 7* to a windlass w, mounted upon a raised platform S of the scow S. Another rope h, having been secured to the outer end of truck R, passes under and half way around a roller ri'm-ounted in a stirrup-shaped bearing upon the outer end of an arm D, and from there back over the roller 0" to a windlass 10, mounted upon the platform A upon the scow S. Thus by alternaely handling the windlass w and w the load on the hoisting-rope can be carried along the entire length of an arm D and raised or lowered, as required.

To secure free passage to the ropes, stirrupbands sare fastened to each arm D to connect with the brace-rods leading to the top of the mast A. The armsD are preferably of sufficient length to reach over a vessel and part of a dock.

The beams C, to which the canvas tents C are secured, are slotted to the entire length of the slot in an arm D, and their slots are of sufficient width to allow the passage and some play for the hoisting-rope 7L. A long sheet of canvas is secured to the outer sides of each beam 0, and the inner sides are connected by a shorter strip, so that when spread as shown in Figs. 1. and 3, it will form a tent which will protect the workmen, the hatches, and the merchandise, yet forming no impediment for the handling of the latter.

The employment of two arms D, each capable of being swung while at work in a horizontal plane to one side of the mast A, will allow the goods to be handled with great dispatch, as both arms could be used in one hatch of a vessel, or two hatches could be worked with one arm for each at the same time, as shown in Figs. 2 and 3 0f the drawings. The work having been completed, the arms D can be swung up by means of hoisting-tackle to an almost vertical position, (shown at D, Fig. 1,) and the vessel can proceed to some'other place, as required.

The armsor boomsE E, secured on a sleeve 1), vertically adjustable on the mast B, are arranged to carry elevator-legsF F, and are preferably of unequal length to facilitate the unloading of two vessels lying alongside of each otheratthesametime. Thesleevebisadjusted vertically upon the mast B in the same manner as the sleeve to upon the mast A by means of an upright shaft n, gearing n, shaft 11 and crank 01 The arms E E are secured to ears 1), like common hinges, by passing a hollow pin 0 through the projecting ears, as shown in Fig. 2, and are held at any desired angle by means of blocks and fall, as shown in Fig. l, or swung up to an almost vertical position when the work is done and the vessel is to be moved from one place to another.

The elevator-pulleys are rotated by means of bevel-gearing 0 and shafts 0 and o, the latter passing through the hollow pin 0, which secures the arms E E to the sleeve 1), and the upright shaft 2', carrying the pulley t", and

provided with a lengthy key-seat i and a.

bevel-gear i is secured by brackets n to the mast B, and passes through a forked bracket 19 secured on sleeve b, which carries along the bevel-gear 1' the key of which is sliding in the groove i ,cut in shaft '6, and making connection wherever the sleeve 1) may be placed on mast B by means of the shaft 1 and the bevel-gear 0 The scow S is provided with a chamber S to receive the grain to be unloaded, and above this an elevator T is erected, the leg T of which reaches to near the bottom of the chamber S I A steam boiler and engine K furnishes the power for working the bucket-elevators in the leg T as well as those in the legs F F. Suitable chutes f lead from the nozzles of the elevator-legs F F into the chamber S in the vessel S, and a chutet is directed from the nozzle of the elevator-leg T to any hatch to be loaded.

The operation is then as follows: The scow S, with all her beams and arm raised, is placed alongside of a vessel to be unloaded and loaded which has previously been fastened alongside of a dock, and two other vessels being brou ght alongside herself and each other at the outer or free side of the scow it now proceeds to lower the arms of both cranes and to ad.- just the sleeves a and b to their proper height, at the same time adjusting the brace-rods on the arms D so as to retain the latter in an almost horizontal position. The beams C are now adjusted and the canvas 0' is spread and the hoisting-rope dropped to wherever itis needed, the arm D having previously been swung over the hatches to be worked. At the same time another gang of men will adjust the arms E E and drop the elevator-legs F F into the hatches of the respective vessels and adjust the chutes ff and t, when the work can proceed, as described,on three hatches simultaneously, while workmen and merchandise are entirely protected from the weather.

By the use of this combined floating crane and elevator a vessel can be prepared to receive the grain from the elevator readily, which will serve as ballast, while the other hatches are discharging, thus getting the vessel ready for sea with great dispatch and being a help to secure her safety.

I am well aware that slotted arms and trolleys secured to sliding frames have been used before, and therefore do not broadly claim their use; but i lVhatI claim, and desire to secure by Letters Patent, is-

1. The scow S, having a mast A, carrying two independent booms D, secured to an adjustable sleeve a by means of the forks a and the hinges 60*, the latter carrying the rollers r r, the trolleys R, carrying the pulleys r the pulleys r ropes h h, hoisting-winches w w, the screw m, crank m shaft m and gearing m, as and for the purposes herein shown and described.

2. The scow S, having a mast B, carrying two independent booms E, secured to an adjustable sleeve f, two elevator-legs F of unequal length, the screw u, gear 91, shaft p and crank 45, with the upright shaft 11, carrying the pulley t", the gearing 0 and 0 the shafts 0, 0 and i pulleys and belts, the elevator T, entering the chamber S the chutes t and f, and the engine K, as and for the purposes herein shown and set forth.

8. A loading and unloading apparatus comprising the scow S, having a chamber S and a mast A, carrying two independent booms D, secured to an adjustable sleeve a and provid ed with trolleys, pulleys, ropes, and winches, the mast B, carrying two independent elevator-legs F F, of unequal length, the booms E E, secured to an adjustable sleeve 1), and engine K, pulleys, belts, shafts, and gear, the elevator T, and the chutesf and 2, as and for the purposes herein shown and described.
