PAUL WILHELM SIEURIN, OF GOTHENBURG, SWEDEN.

SPEGIFICATION forming part of Letters Patent No. 739,933, dated September 29, 1903. Application filed August 27, 1902. Serial lie-121,177. (No model.)

vented certain new and useful Improvements in Apparatus for Collecting and Hoisting Goods, of which the following is a specification, reference being bad to the accompanying drawings.

This invention relates to a device for automatically collecting and hoisting up goods-- for instance, coal or corn-out of the hold of a ship.

According to this invention a scoop orv bucket constructed in a special manner is used, which bucket is dragged forward in the hold for the goods and then hoisted up, the filling of the said bucket taking place automatically, so that the number of workmen necessary for unloading is considerably reduced. ,The invention is illustrated in the annexed drawings, in which- Figure l is a side elevation, and Fig. 2 a bottom plan view, ofthe scoop or bucket. Fig. 3 represents the hold of a ship, the hatch being removed. Fig. 4. is a section of such hold; Fig 5, a detail of construction. Figs. 1*, 2", 3* are respectively side elevation, sectional top plan, and transverse section of a modification of the dogging device. Figs. 4., 5, and 6 are details of said modification. Figs. 7, 8, and 9 illustrate steering devices. Fig. 10 is an enlarged planview of a portion of the hold of the ship, showing my invention in place; and Fig. 11 is a detail of an attachment device.

The bucket is designated by the numeral 1. The under side or dragging surface 2 thereof is extended forward to form a rounded edge 3, and it is desirable that this extension shall be such in respect to the body of the scoop or bucket that goods received in the body of the scoop so far counterbalance those upon the extension that the scoop will tilt on the extreme rear upon striking against an obstacle for instance, a trough, channel, or such. Moreover, this extension serves to make the bucket heavier, so that this latter by itself effectively engages with the goods. A bail 4. is provided, which is to be attached to the dragging chain or rope of a winch 6. One or more stops 7-for instance, one on each side of the bucket are so located that the bail 4 lies almost parallel with the under side 2 of the bucket when this latter is being dragged, and in order to hold the bail in this position, which may be desirable for goods so light as coal, there is a locking-dog, which is dropped upon the bail. Other shoulders 8, against which the bail 4. bears in hoisting up, are arranged opposite those aforementioned. In order to facilitate the engagement of the bucket with the goods and its filling therewith, there are on the under side or the sliding surface 2 ribs 11, which besides serving as reinforcements and runners are extended beyond the edge 3 in the form of teeth or guards 12, which grasp the goods strongly and, so to say, loosen up the same.

" Concerning the shape of the bucketin other respects, it may be'observed that the sides provided with the bail-pivots 13 are planes, whereby said pivots need notproject more than is necessary for forming a bearing for the bail, and there is no material obstruction to dragging the bucket forward in the goods. It will also be observed that the rear edge 5 of the bucket is straight in order that the receptacle may ride on the said edge in being hoisted up without rocking sidewise.

The bucket is provided on the upper side with hooks 14 for coupling to a rope and at the back or bottom with two or more rollers a, so that when empty or even when fully loaded it may be pushed about on a surface relatively evenfor instance, on the floor of the hold'or magazine.

The bold or magazine 9, Figs. 3 and 4:, is provided with chains, ropes, or such like 16, which are attached at the lower corners of such compartment, and the upper ends of which are connected to the edge of the hatchway by engagement with permanent staples 33, Figs. 10, 11, to which blocks 17, are also secured at the beginning of unloading. These chains, ropes,&c., may be detachably connected at their upper ends, so that they may be attached to other points in the hold or magazine in order to afford suitable points of support for the rope or chain 15 for dragging the bucket or scoop, which chain runs about a tackle -block 18, which may be ad- ICO justed along any given chain 16 as the unloading proceeds. Goods from any desired point in the hold or magazine may be collected thus, and the attendant belowhas only to uncouple the scoop from the drag-rope 15 after it is filled and to couple it to the hoisting-rope.

As to the stop 7 and the locking-dog 10, these parts are shown upon a slide-piece (see Fig. 5) adjustable along a slot bin order that the bail 4 may be brought to difierent angles in relation to the sliding surface 2 of the bucket. For instance, in unloading of ores, which are very heavy goods, it is advisable to have the bail adjusted more toward the sliding surface 2 in order that the goods may be better grasped.

A modification is shown in Figs. 1, 2 3", 4, 5, and 6, in which the pawl is replaced by a bolt 10, which may be moved in and out of the wall of the receptacle 1, and the inner edge of which is surrounded by a casing 23, riveted to a slide-plate on the inner side of. the receptacle and containing a spring 21, which presses the bolt outward, and a bar 17' with beveled edge 18, which acts against a bevel 19 on the bolt in such manner that this will be pressed inward when the bar is drawn out. A spring 20, attached to the plate 15 and arranged in the casing 23, tends to draw the bar 18 in, so that the' spring 21 may move the bolt outward to lock the bail after the latter has been drawn past the outer beveled surface of the bolt. The

videdviz., one on both sides of the bucket l-it may be advisable to connect the bars 17' by means of a common bar 22, so that the bolts can be drawn in simultaneously.

In Fig. 7 is shown a socket 27 for reception of a bar 29, which serves for steering the receptacle 1 by hand during the maneuvering of the same. In Fig. 9 this socket is replaced by two ears 28.

Having thus described my invention, what I claim is 1. In an unloading apparatus the combination of a chain 10 extending from a suitable anchorage through the hatchway, and thence to variable points in the hold, of blocks attached to said chains at the point where they enter said hatchway, blocks adjustably attached to the chains in the hold, a cable rove through said blocks, means for winding said cable, and a scoop operated by the cable.-

2. In an unloading apparatus, the combination of a chain 16 extending from a suitable anchorage, through the hatchway, and thence to variable points in the hold, of guide-blocks attached to said chains, adjustable blocks attached to the chains in the hold, a cable rove through said blocks, means for winding said cable, a scoop operated by the cable, said scoop being provided with a pivoted bail to which the cable is attached and adjustable stops, and adjustable dogs to engage said bail when in operative position, substantially as described.

In testimony whereof I afiix my signature in presence of two witnesses.

PAUL WILHELM SIEURIN.
