IMPROVEMNT IN MACHINERY FOR MOVING COAL OR OTHER MINERALS.

The Schedule referred to in these Letters Patent and making part of the same I, J onsv EASTBURX .Woorrnsg of Reading, in the county of Berks and State of Pennsylvania, have invented certain improvements in Machinery for Moving Anthracite Coal, or other minerals, of which Vthe following is a specication.. l

. AYtturc and Object of the Invention.

At the terminal points of the important coal-bearing railroads it becomes necessary, in the absence of a constant and adequate su ppl y of vessels or boats, to empty the railroad cars of their contents upon the wharves at such terminal points, in order that the cars may bepromptly returned to the lnines for reloading; thus there is often a large accumulation of coal upon the.wharves, which heretofore has only been placed in the Aholds of vessels or boats by means of hand wheelbarrowsy and this being a very expensive, as well as a laborious and very slow operation, I have devised the following-described apparatus for the purpose of cheapening and facilitating the movement of the coal from the wharf to the vessel.

General Description.

A is an endlessbelt or band, of wire rope or other suitable material, upon which, at any desired inter- "vals, should be placed the carriers B B B.

Motion is imparted to the endless band A by means of the drum C, which, in turn, is impelledrby a steamengine, or any other convenient or etlicient motive power. Y

D is a barrow, of any convenicntcaparity. I prefer,

however, that it should contain live hundred and sixty pounds, or one quarter of a gross ton of coa-l. This barrow is so constructed that it is readily lifted up at its rear when loaded, and when so lifted its contents will be discharged from the front end without dili` culty. v

At the rearend of the barrow isa drag-bar, E, which is secured to the barrow by means of the straps c c, but which do not hold the bar so tightly as to prevent its vertical movement when necessary. v

The lower end `of the bar E is bifnrcated, for the purpose of straddlin g the endless band A, as hereinafter described.

G is an inclined plane, the object of which is to elevate the barrow D to a sniiicient height that the contents may-witll-facility be dumped into the hold of a vessel lying at the wharf', beyond the outer end of the plane.

lo this outer end ofinclined plane G is hinged the vplatform H, which, by means of the supporting pins K l, is rendered adjustable, between nprights J J to any height that may be Arequired for facilitating the dumpage of the coal int-o vessels, under the varying conditions of the rise and fall of tide and thc settling f the vessel under increasing load.

The platform H is hinged, so that when not in use it may be hoisted to within the wat-er line of wharf.

On the under side of platform H is placed a drum, M, around which the band A passes, and to which it is guided by the sheaves N O. Y

I I are tramways, upon which the barrow I) is moved, and which guides its direction.

Having thus described the construction of my improved apparatus, I will endeavor to describe its inode otoperation, which is as follows:

Steam, or other motive power, having been applied to cause drum C to revolve, the endless band A is thereby set in motion.

The barrow D, having been lledwith coal, is placed upon the tramway. rlhe bar Eis then allowed to fall so that its lower end shall straddle the band A.

1When, by the movement of the band A, the carrier B is brought into contact with the bar E, the barrow I) is started and impelled until it reaches the sheavc N, at which point the rope is deflected, and passing downward, thereby becomes detached from the end of bai-E. rlhe barrow having thus been delivered to very near the required point, it is only necessary to move it to the chock-block R, when the rear end can be raised and the contents discharged, after which it is placed upon the return tramway, the bar E placed in position upon the band A, and the barrow returned to the point at which it may be desirable to rell it.

Claims.

1. rIhe combination of the two parallel tracks l? P, an endless rope passing forward at the center of one track and returning at the center of the other, and a4 platform extending beyond' the ends of bot-h tracks, and beyond sheaves which conduct the said rope below the platform, as described.

2. The said platform, arranged, in respect to the outer ends of the tracks, as described, when adjust-
