MECHANISM FOR GATHERING BULK CARGOES BENEATH HATCHE'S."

SPECIFICATION forming part of Letters Patent No. 762,785, dated June 14, 1904.

Application filed January 2 1903.

To all whom it may concern.-

Be it known that we, CHARLES H. WELLMAN and JAMES E. A. MOORE, both citizens of the United States, and residents of Cleveland,

Ohio, have invented certain Improvements in Mechanism for Gathering Bulk Cargoes Beneath Hatches, of which the following is a specification.

The object of our invention is to provide a mechanical device whereby coal, ore, or other granular material contained in the hold of a vessel can be drawn into position beneath a hatch, so that it can be raised from the hold by means of a grab-bucket or other hoisting device.

In the accompanying drawings, Figure 1 is a side elevation of a gathering device constructed in accordance with our invention. Fig. 2 is a plan View of the same with some of the parts omitted in order to show parts which would otherwise be hidden thereby. Fig. 3 is a side elevation illustrating a modification of one of the features of the invention. Figs. 4, 5, and 6 are views illustrating 5 different methods of securing the device in place in the hatch, and Figs. 7 and 8 are respectively a vertical section and a plan. View of .part of the device on an enlarged scale.

In Fig. 1 part of the deck of avessel is rep- 3 resented at 1 and the coaming of one of .the

hatches at 2. Spanning the hatch is a carriage 3, suitably mounted so as to traverse along the hatch and provided with means whereby it can be clamped in placein any desired position of adjustment. As shown in Fig. 1, the carriage is mountedup'on wheels 4, running on the deck on each side of the hatch-coaming, and'is clamped to said hatchcoaming by means of hooked bars 5; but va- 4 rious other means of holding the carriage in place may be adopted-for instance, in Fig. 4 we have illustrated a pair of gripping-tongs 6 engaging the bulbat the top of the hatchcoaming, while in Fig. 5 we have shown a magnet 7, intended to be held by magnetic attraction to the steel deck of the vessel, and in Fig. 6 we have shown a pair of clampingjaws 8 engaging a rail 9, extending alongside Serial No. 137,583. (No model.)

of the hatch, and which may also receive the wheels or rollers upon which the carriage is mounted. The carriage 3 has an annular rail :10, and upon the latter is mounted a turn table 11, which carries the hoe or scraper and the mechanism for operating the same. As shown in Fig. 1, said turn-table 11 has brackets 12, in which is pivotally mounted a swinging frame 13, and in the latter is vertically guided a beam 14, which can be raised and lowered in said swinging frame by means of a hoistingrope15, or a rack and pinion, or other suitable mechanism operated by a motor on the turntable. Projecting from the lower portion of this beam 14 is a bracket 16, andto the latter is pivoted at 17 an arm 18, which carries at its outer end the hoe or scraper 19, said arm 18 being counterweighted, as shown at 20, so that the hoe has a normal tendency to swing upwardly. Connected to the arm 18 in the rear of its pivot is a rope 21, which extends around a guide-sheave 22 on the beam 14, and thence to any suitable form of hauling mechanism mounted on the turn-table 11, and another rope 23 extends from a connection 24 on the beam to another hauling device mounted on the turn-table. It will therefore be seen that provision is afforded for moving the beam 14 *from end to end of the hatch, for moving it throughout a half-circle at either end of the hatch, for moving it bodily in a vertical direction, for swinging the arm 18 vertically on its pivot 17, andalso for swinging the beam 14 laterally on the pivot of the frame 13. Hence all needed facilities are provided for causing the hoe or scraper 19 to engage with thematerial in the hold of the vessel at any point within the range of projection of the arm18 and to draw the sameinto position directly beneath the hatch, where it is accessible to a grab-bucket or other hoisting device operated through the hatch. In some cases the hoe may be mounted directly upon the beam or upon a rigid arm thereon; but it is preferable to mount it upon an independently-swinging arm, as shown. The arm 18 may, however, be pivoted directly to the lower end of the beam 14 at thepoint 26, as shown in Fig. 3,

and connected to a suitable hauling device by frame 11 and also for rotating the latter and for moving the carriage 3; but we prefer for this purpose gearing operated by electric motors, because of the facility with which power can be conveyed to the latter and the general convenience arising from their use.

Having thus described our invention, we claim and desire to secure by Letters Patent 1.
