HVIPROVM ENT IN GRAIN-ELEVATORS.

Specification forming pari of Letters Patent No. 48,495, dated June 27, 1865; antedated June 12, 1865;

Reissue No. 3,206, dated November 24, 1868.

To all whom it may concern,.-

Beit known that FRANCIS TAGGART, LEWIS S. OHIOHESTER, and CLARK W. MILLS, of Brooklyn, in the county of Kings and State of New York, .did invent and make a certain new and useful Improvementin Floating Elevators for Grain, 8rd, and the following is hereby declared to be a full, clear, and exact description of the said invention, reference being had to the annexed drawings, making part of this specification, wherein- Figure l is a cross-section of the improved iloating elevator, and Fig. 2 is a longitudinal section of the same.

Similar marks of reference denote the saine parts.

Grain any many other articles generally arrive at tidewater in canal-boats and barges, and usually in bulk. Heretofore it has been usual to discharge such grain, by a steam-ele vator, into a storehouse, or else into a vessel, for transportation, by means of a floating elerl"hese floating elevators have to be placed between the canal-boat or barge and the vessel or storehouse, and in Wet weather the discharging of the cargo often has to be suspended, because the hatches cannot be left open for introducing the elevator.

The nature of the said invention consists in an elevator applied between two iioats, and in a deck or house covering the space between said floats, and into which space the canalboat or barge is floated, so as to be under cover, and at the same time the elevator is made much more steady, in consequence of its base being broader, and space is furnished in the deck or house for the temporary reception and storage of grain or other materials, or its transportation from place to place, and the same deck or house can be used for drying, cleaning, and cooling grain previous to its delivery on shipboard, or for grinding grain or feed, or any like Work arising in connection with the materials transferred.

In the drawings, a a are hollowr floats or narrow vessels, with timbers extended sufficiently above the decks, as at b b, for the reception of a platform or deck, c, that connects the floats together, and at the saine time ample space is left between the floats for a canal-boat or barge to be drawn in, and have its cargo discharged while beneath, and protected by said platform or deck c.

The floats a a should be provided With rndders, as usual, and with propellers, driven by a suitable engine or engines, so 'as to be propelled or moved from place to place, as occasion may require. the propeller should also be iitted to unconple, in order th at they may be employed for actuating the elevator d, or performing any other work that may be done on the floating elevator.

A house, f, may be constructed upon the deck or platform c, of a size and shape adapted to the work to be performed in it.

A tower is represented that can contain a drier and cooler for the grain, and also a second elevator, for passing the grain to a vessel or storehouse, and in this house f fanning-mills and machines for cleaning or grinding grain may be introduced, if desired.

The elevator d is set, to be raised or lowered, in a frame, g, by means of a Winch, h, from which a rope or chain passes over the pulleys fifi to Said elevator d, this device being pro vided for raising the elevator as the canal-boat or barge is drawn inl between the floats, and for lowering said elevator as thepOntents of the vessel are discharged. The elevator d is represented Wi th a spout, k, that passes into the trunk Z, so that the delivery pipe or spout will not become disconnected or allow the material to spill out as the elevator is raised or lowered. The elevator d should be inelosed in a house or tower, as seen by dotted lines in Fig. 2.

A canal-boat is represented at m, and the material is shown in bulk as being delivered into the housef by the elevators d.

The elevators heretofore made have acted transversely of the vessel to be discharged, the axes of the drums thereof standing lengthwise of the vessel. This is inconvenient in many instances Where the elevator-drums are large and the boats. narrow. This elevator can be more conveniently applied than those before named.

What is claimed, and desired to be secured by Letters Patent, is

The engines employed for l. A iloating elevator formed by two vesl order that the elevator niay aet longitudinally sels or oats connected together, and leaving of the vessel to be discharged, substantial] y as a space for a boat or barge, in combination specified.

with an elevating apparatus. Dated October-22, A. D. 1868.

2. An elevator, d, itted to be raised or loW- I; GEORGE I L NICHOLS.

ered, in combination With the floats a a and platform connecting said floats and support` l ing the elevator, substantially as set forth.

3. A grain-elevator fitted upon a float, and Witnesses:

arranged so that the axis of the elevator-drum GHAS. H. SMITH,

is at right angles, or nearlyr so, to the float, in GEO. T. PINCKNEY.
