To an whom it may concem."

Be it known that I, Aa'rmm G. Jorms'mn, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented. 5 certain Improvements in Means for Turning Hoisting-Buckets, of which the follow-- ingiis a specification. y invention relates to certain improvements in the mechanism for turning hoisting buckets.

The object of the invention is to so construct the mechanism that the bucket can be turned after it has been lowered into the hold of avessel and at the same time shifted so that it will extend for a considerable dis:

tance 'underthe deck, and thus more material can be removed from the hold of the vessel than-heretofore and a larger bucket can be used than when the hoisting mechanism is not provided with a bucket turning device. I j

y The hatchwa s of a vessel are limited in wldth but can :of any length desired, the length of the hatchway extending across the vessel, so that, by the use 'of a narrow and 2-2, Flg. 1; Fig. 3, is a. planview on theline 3-3 Figfl.

A is the ame of the carriage having bearin afor the axles B ca g the 40 groov wheels 6 which are adapted to travel on the tracks of a. crane or through an overhead structure.

C is the drum shaft *on which are mounted the two hoist' drmns a, 0'. This drum 46 shaft is mounte in bearings a on the frame A and on the drum shaft is a gear wheel C which meshes-with inions d on the shaft of the electric motors on the frame A." These motors are controlled from the platform A depending from one end of the'carria A.

Ifhs the hoisting bucket aving jaws e, e

whlch are opened or closed by mampulating the ropes i, 2'. These ropes are adapted'to which are mounted member means, a. bucket, sheaves on'the bucket, ropes sheaves e, e on the bucket, and one rope is coiled on the drum 0 and the other on the drum'c.

Depending fromthe underside of the carria A is a frame F having an open center, an this frame has an'internal track 7 for the wheels 9 carried by an open r' G having at its lower edge, in thepresent mstance, a segmental rack g with which meshes a drivm gear wheel 71.. The ropes 5,17 pass from t e drums through theopen ring and around sheaves e on the bucket and their. I

ends are secured to the ring at g. The pinion h is mountedv on a vertical shaft H adapted to bearings in the frame F and-on the up er end of the shaft is a worm wheel Jt' mes with a worm h on the shaft of a motor I By the above construction it will be seen that any suitable mechanism can be used to raise and lower the bucket, and by throwin in the motor H the bucket will',not

on y be turned to a position at ri ht angles to its normal osition, but wi also be moved to-one si e'or the other of the hatchway, according to the direction of motion of the toothed segment. Thus by this means a long narrow bucket of great capacity can be lowered through the hatchway and then turned at right angles to the longitudinal line of the hatchway, and at the same time moved toward one side so as to extend a This motor is also controlle from the platform A.

considerable distance under. the deck and thus receive material at a point inaccessible to the ordinary non-turning bucket. The hatchways of a vessel can be arranged com parative y close together, so that a bucket of this type will removethe greater bulk from the hold of the vesseland consequently 'verv little hand shovelin is required.

' e I have shown oisting mechanism havin two drums, it will be understood that ifierent types of mechanism having one or more drums may be used without departing from the essential features of the 'inventlon.
