RECLAIMING-BUCKET.

Application filed May 23, 1918.

Improvements in Reclaiming-Buckets, of

which the following is a specification.

This invention relates to improvements inv buckets and more especially to reclaiming buckets designed for use in moving coal, and

, the like, in connection with an overhead carrier and cable system.

An object of my invention is the production of a bucket of the character described which is a combination scraper and hoisting bucket. Another object of the invention is the production of a bucket which can be readily dumped at any desired point along the line of an overhead carrier system. Other objects of my invention are described herein.

The invention is well illustrated in the accompanying drawing in which Figure 1 is a rear elevation of the bucket; Fig. 2 is a side elevation thereof; Fig. 3 is a top plan view thereof; Fig. 4: is an enlarged fragment showing the connection between the coupler bar and coupler link; and Fig. 5 is a view showing the bucket in various positions, both as a scraper and hoisting bucket.

Similar characters of reference indicate like members and parts of members throughout the several views on the drawing.

The details of the drawing show that numeral 1 indicates the reclaiming bucket generally, which is composed of a somewhat inclined rear wall 2, a bottom 3 and the two side walls 1 and 5 which terminate at the open end 6. The teeth 7, 7 may be fastened to the forward edge of the bucket bottom, as usual in scraper buckets.

The numeral 8 indicates a bail which is hinged to the bucket exterior at 9 and 10 and forward of the center of gravity thereof, said bail having an eye 11 with which atraction and hoisting cable may be connected. The numeral 12 indicates a coupler bar rigidly fastened upright of and to the exterior of the bucket rear wall 2 adjacent the middle thereof, the upper end of said bar projecting somewhat above or beyond the upper edge of said wall. Numeral 13 indicates an aperture formed in the bar' 12 adjacent the upper end thereof and adapted to serve as a guide for the coupler link, as hereinafter described.

Specification of Letters Patent.

Patented Jan. 28, 1919.

Serial No. 236,081.

Numeral 14: indicates a coupler link connected at its forward end to the bail eye 11 by the link eye 15, and having its opposite end slidably arranged within the coupler bar aperture 13, the latter being somewhat longer than the width of said link to permit of substantial vertical play therein by said link. The link 14 is provided with a plurality of undercut hook members 16 and 17 on its upper edge, said hooks being undercut to correspond with the sloping face 18 of the bar 12, the hook 16 being formed adjacent a handle member 19.

Numeral 20 indicates a pile of material to be handled, such as coal, above which a carrier member 21 is adapted to operate back and forth upon a carrier cable 22 and to which are connected suitable carrier traction cables 23 and 24: for moving said carrier. Numeral 25 indicates a bucket traction and elevating cable extending over a pulley in the carrier 21, thence over a bucket pulley 26, thence over another pulley in said carrier, and thence to a suitable source of power. In Fig. 5 the bucket 1 is shown in three positions, viz: a, which is preliminary to filling it; 1), its position after being filled; and 0, its position after being filled and elevated for transportation by the carrier 21.

In operation, the bucket 1 is placed in position a and the hook 16 is engaged by the operator with the sloping bar face 18 and maintained until the bucket begins to move by the draft of the cable 25, as indicated in Fig. 1. Thereupon, the bucket is drawn forward by the traction cable as a scraper and filled, being moved forward until it is substantially below the carrier 21 and at position b. If the cable draft is steady up to this point the engagement of the hook 16 is maintained with the bar face 18. Otherwise, the operator must maintain such engagement. Thereafter, and when the bucket arrives in position b, the bail 8 swings backward, the link 14 being carried therewith. Thereupon, the operator engages hook 17 with the bar portion 18 and holds such engagement until the hoisting power commences to elevate the bucket, from which point the hook engagement is maintained by the weight of the bucket and contents, said bucket thereafter assuming a position substantially as indicated by c in Fig. 5. Thereafter, the bucket is carried horizontally by the carrier 21 until the place of deposit is reached when it is lowcred into contact with the ground, or the pile of material. alreadydeposited, whereby the hook 17 is disengaged from the bar face 18. Thereupon, the bucket is again elevated a bail; a coupler membercarriedbythe rear end of the bucket and provided-With r v S v an overhanging abutment; and a coupler link movably connected with the bail aiild adapted to effect a "disengag'eable hook @611} nection with said coupler 'inen br abutment 7 from beneath 'samefsaid hook connection being maintained draft oii saidflink aiid automatically disengaged tvherfidraft 'oii' said link ceases. 2.
