DREDGlNG-BUCKET.

SPECIFICATION forming part of Letters Patent N0. 619,581, dated February 14, 1899.

Application filed September 21, 1898. Serial No. 691,515. (No model.)

To aZZwhom it may concern.-

Be it known that I, HARALD J ULIJos KRO- MANN, of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Dredging-Bucket, of which the following is a full, clear, and exact description.

The object of the invention is to provide a dred gin g-bucket especially adapted for dredging sand and which is simple, durable, and

economic in construction, capable of. being readily manipulated, and effective in service.-

Another object of the in vention is to provide a sand-dredging bucket the bottom of which may be readily opened and closed, and, furthermore, to provide means whereby the bucket may be dropped perpendicularly, carried over any desired spot where dredging is to be done, and readily inclined so that its spout will enter the surface from which material is to be removed.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be hadto the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of a scow and the improved dredge applied thereto, the bucket being shown in positive lines as partly lowered and in dotted lines as further lowered and carried to a position over the surface with which it is to engage. Fig. 2 is a View similar to Fig. 1, the bucket being shown in working position. Fig. 3 is a side elevation of the scow having the improvement applied thereto, the dredge-bucket being shown as elevated and in dumping position in positive lines and in receiving position in dotted lines. side elevation of the bucket, drawn on an enlarged scale, the bottom being open. Fig. 5 is a rear end view of the bucket. Fig. 6 is a vertical section through the bucket, the bottom thereof being closed and the section being taken practically on the line 6 6 of Fig. 5. Fig. 7 is a plan View of a guide device adapted for attachment to the support for the dredging device.

Fig. 4 is a The dredging-bucket A is preferably made oval in transverse section and comprises a body open at the top, the top portion of the body having a scoop-spout 10, either made integral therewith or attached thereto, and at the upper end of the body of the bucket a bail 11 of any approved description is located. The bottom 12 of the bucket is connected to one side of the same by hinges 13 or their equivalents, and at the narrower sides of the body

longitudinal bars

14 and 16 are secured, which bars preferably extend from the top to and beyond the bottom, each bar being provided at its lower end with a head, the head of the bar 14 being designated as 15 and the head of the opposing bar 16 as 17, and each head is provided with a recess, the recesses of the heads of the two bars being made to face in opposite directions.

Preferablyin the construction of the dredgebucket the bail 11 is pivoted to the body at the upper ends of the said

bars

14 and 16. The bottom 12 is held closed by means of a lockbar 18, pivoted on the under face of the bottom, at the center thereof, by means of a pin 19. the other, forming a handle 20, and both ends of the lock-bar are adapted, when the bar extends longitudinally of the bottom, to enter the recesses in the heads of the

side bars

14 and 16, as shown in Fig. 5.

At the bottom portion of that side of the bucket opposite the hinges 13 and at the center of said side ahorizontal yoke 21 is secured, a guide-pulley 22 being pivoted in said yoke, and the bottom is provided with a lip 23 at its free edge, which lip when the bottom is closed on the body extends within the yoke 21. A chain or a rope 24 is attached to the lip 23 and is carried over the guide-pulley 22'.

In the application of the device a turn-table B is usually mounted upon the deck of the scow. A boom 25 is pivoted on the said turntable, being provided with a guide-pulley 26 at its upper end, and the boom is pivotally connected at the top by a suitable brace 28 with a mast 27, stationarily attached to the scow. A chain or a cable 29 is attached to the bail of the bucket, said chain or cable 29 being carried over the pulley 26 and over a One end of the lock-bar is longer than second guide-pulley 26, located on the turntable, to any source of power, and the rope or chain 24, utilized for closing the bottom of the bucket, is carried aboard the scow in any desired manner and is operated by hand. At one side or at both sides of the scow, near one end or both ends, a horizontal yoke 30 is secured, and in each of said yokes a guide-pub ley 31 is mounted to turn. (See Fig. 8.) In order that the bucket may be readily manipulated from the deck and directed by hand to any portion of the bottom, a handle 34 is attached to the yoke 21, which handle is of sufficient length to reach to the deck when the bucket is in operation. The handle may be made extensible in any well-known manner.

In operation the bucket is lowered in a vertical position, as shown in Fig. 1, guided by its handle, the bottom being closed, and by means of the handle 34 the bucket is swung byhand and lowered over the side of the scow to any desired point where dredging is to be done, the boom being swung outward at the same time, since the hoisting-chain of the bucket passes over the boom, and after the bucket has been carried over the point to be dredged the lift chain or cable 29 is carried by hand over the guide-pulley 31, located on the scow at the side over which the bucket is dropped. When the hoisting cable or chain is thus carried to an engagement with the guide-pulley 31, as shown in Fig. 2, the bucket will be so inclined, assisted by the handle, that the spout will enter the surface to be dredged, and by drawing the cable or chain inboard the bucket will be filled, as it can be held in contact with the sand by the handle. hen the bucket is filled, it is elevated and carried over the hold of the scow, as shown in Fig. 3, and the bottom is made to drop by striking the handle 20 of the lockbar with a suitable instrument, or the opening of the bottom may be rendered automatic by causing the lock-bar 20 to engage with an.

gdjacent projection located over the deck or old.

The entire device is exceedingly simple, durable, and economic and is particularly adapted to the purpose to which it is applied.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. Adredging-bucket, consisting of a body, a bottom hinged thereto, latch-bars each extending longitudinally of the body on opposite sides thereof and beyond the lower edge of the same, at which point said bars are each formed with a recess, said recesses being turned in opposite directions, and a lockbar pivoted to the bottom and being arranged to fit in said recesses when the bottom is closed, whereby to lock the same, one end of said lock-bar being extended beyond the adjacent latch-bar and adapted to form a bandle for unlocking said lock-bar, as and for the purpose set forth.

2. A dredging-bucket consisting of a body provided with a scoop-spout, a drop-bottom for the body, the bottom being hinged thereto, a lock-bar pivoted to the under surface of the bottom, extending beyond opposite edges thereof, latch-bars secured to the outer surface of the body and extending beyond the bottom thereof, each latch-bar terminating in a recessed head, the recesses of the heads facing in opposite directions, being adapted to receive the end portions of the lockingbar, a yoke secured to one side of the body near the bottom, a handle secured to the yoke, and a guide-pulley located within the said yoke, whereby a cable or a chain attached to the bottom may be carried over the said guidepulley, for the purpose set forth.

3. A dredging-bucket consisting of a body oval in cross-section, said body being provided with a scoop-spout at one end, a bail at the same end and a bottom hinged at the 0pposite end,latch-bars attached to the narrower outer side surfaces of the body, longitudinally thereof, the heads of the latch-bars extending below the bottom of the bucket, the said heads being provided with recesses facin gin opposite directions, a lock-bar centrally pivoted upon the under surface of the bottom, the lock-bar extending beyond the narrower edges of the bottom, one end of the lock-bar serving as a handle, the end portions of the lock-bar being adapted to enter the recesses in the heads of the latch-bars, a horizontal yoke secured to the outer side portion of the body in front of the pivot of the lock-bar, a guide-pulley pivoted in the said yoke, and a lip formed upon the bottom, extending within the said yoke, the lip being adapted to receive one end of a chain or cable arranged to be passed over the guide-pulley, for the purpose set forth.
