Letters Patent No. 100,259, dated March 1, 1870; antedated February 19, 1870.

IMPROVEMENT IN COAL-HQIS'IING APPARATUS.

The Schedule referred to in these Letters Patent and making part of the same.

Be it known that I, LEWIS S. GHICHESTER, of Brooklyn, in the county of Kings, and State of New York, have invented and made a new and useful Improvement in Apparatus for Hoisting Goal, 870.; and 1 do hereby declare the following to be a full, clear, and exact description of the said invention, reference being had to the annexed drawing making part of this specification, wherein Figure l is a plauof said hoisting apparatus below the line :2 2;;

Figure 2 is a section of the same with the bucketin a position to be lowered or raised; and

Figure 3 shows the apparatus in the 'position assumed when the bucket is being emptied.

Similar marks of reference denote the same parts,

- In hoisting coal and other materials in a bucket, it is ii'equently ditiicult to swing the bucket tothe point required for dumping, and generally the bucket has to be turned over by hand.

My invention consists in an inclined frame with stops for the bucket, and hoisting pulleys, combined with a stationary frame and chute, in such a manner that after the bucket has been drawn up 'the inclined frame is swung in, and in the act of sodoing the bucket is inverted to empty its contents. The reverse movement carries the bucket out and then allows it to be lowered into the hold of a vessel or other place, from which the coal or other materials are taken.

In the drawing a is a stationary tiame carrying the chute b, and c is a swinging frame, hinged at (Z to the frame a, so that it can stand at any desired inclination, as in fig. 2, or said frame can be drawn up to the frame a, as in fig. 3.

The rope or chain c is employed between a and c to prevent the frame 0 swinging out too far, and to regulate the position where the bucket will descend, thus accommodating the position of the hold of the vessel or hatchway through which the bucket passes.

The bucket f is made with a bail, g, from the an glcs of which the ropes or chains it pass over the grooved rollers or sheaves k 7:, in the frame a, and

'over the rt-n l, in the frame a, to an y suitable power,

.. will be drawn bodily up, and the straight top part of the bail g comes up into and agaiustthe notches of the stops 1:, on the frame 0, and the further movement causes the frame cand bucket to swing toward the frame a, in doing which the handle 1' comes into contact with hooks o o, placed at the side of the chute b, and causes the bucket to be tipped, shown in fig. 3; and its contents emptied into the chute b.

The stops it support the bail g of the bucket sufliciently to cause its weight to aid in throwing the frame 0 out again, so that the bucket will descend in the proper position. If the stops at were not used, the bucket woiild descend into the chute instead of the frame '0, and bucket swinging out when the rope or chain It is slackeued.

This device is reliable, and renders it unnecessary to tip the buckets by hand.

What I claim, and desire to secure by Letters Patent, is

The buck-ct f, provided with the handles 1', in combination withthe bail 9, stops a, swinging frame 0, and pulley It, the parts being arranged and operating substantially as set forth.

Also, the stops 1:, upon the swinging frame c, in combination with the hoisting rope or chain h, bail g, and bucket]; as amLfor the purposes specified.

In witness whereof I have hereunto set Ill) signature this 2d day of August, A. 1). 1,869.

LEWIS S. GHI'OHESTER.

Witnesses Geo. D. WALKER, Geo. T. PINCKNEY.

These serve to tip the bucket, as hereafter.
