S. W. WOOD, OF CORNWALL, NEW YORK. Letters Patent No. 60,313, dated December 4, 1 866 SPECIFICATION". ,TO ALLWHOM IT MAY conceals;

Be it knownthat I, S. W. WooD, of Cornwall, in the county of Orange, and State of New York, have invented a new and improved Grain Elevator; and I do herebydeclare that the following is a full and exact description thereof, reference being had to the accompanying drawings, making pa'rt of this specification.

Figure 1 being a central, longitudinal, vertical section of an apparatus representing one method of applying my invention.

FigureZ, a vertical section of an apparatus showing a different method of applying the invention. Like letters designate corresponding parts in both figures. The nature of my invention consists in the combination of an air pump with an exhaust-pipe, for drawing up the grain, and with a conveying-pipe for conducting away the grain, substantially as'hereinafter set forth.

There may be different constructions of pumps to accomplish this purpose. The accompanying drawings represent the two general methods of applying the blasts. Figure 1 represents the application of a reciprecav ing pump for. the purpose; and figure 2 a rotary pump or blower.

In fig. 1 let A represent the cylinder, and B a reciprocating piston, which may be driven directly by a steam engine, as indicated, or by any other convenient power. The grain is drawn by the exhaust action of the iston up through'a pipe, 0, which'extends to the grain to be removed, and may be flexible, so'as to be readily ifted from place to place. In this case there is a valve, 6, in the induction pipe, 0, to prevent the return of t 3 air. Here the grain is elevated to the chamber a, in the pump, by the exhaust blast produced in theipipe C. When the piston B is again driven forward it compresses the air before it, and opens a valve, 02, which admits it to the conveying pipe D. Here the grain is carried along by the air compressed, or a force blast, to any height or distance where the pipe may lead, the force of the blast being proportioned to the height to which the grain is to be raised. A portion or all of this pipe also maybe flexible, as circumstances may require. -A wiregauze partition, f, or its equivalent,'separatcs the exhaust chamber, a, from that portion of the cylinder A, in which the piston moves, to prevent the grain from following the'piston'back, and keep it in the path of theblast proceeding to the conveying pipe D. By employing two pistons, B, and two exhaust chambers, a, the motion of the blasts may be made continuous.

In fig. 2 a rotary blower is represented. The rotary piston or wheel, B, is provided with curved hollow arms, 9 g, which, by centrifugal action, force the air and grain commingled. from the central inlet, a, where'the exhaust pipe is attached, into an eccentric passage, (1, inside of the periphery of the case A, whence they are conducted through the conveying pipe, D, as before described.

This method of conveying grain or-other substance of a like character, has the important advantages of great facility in reaching the grain in the holds of vessels or other places, by merely extending the exhaust pipe thereto; of conveying the grain to any distance or height with equal convenience, by the conveying pipe; of economizing the power used to the greatest possible extent; ofextreme simplicity and cheapness of apparatus required, and of the utmost facility of transportation from one place to another.

What I claim as my invention, and desire to secure by Letters Patent, is-- The combination of a pum A B, exhaust-pipe O, and conveying pipe D, arranged and operating substantially as and for the purpose herein specified.

S. W. WOOD.
