IMPROVEMENT IN GRAlN-CONVEYERS,

Specification forming part of Letters Patent No. 211,351., dated January 14, 1879; application iiled May 23, 1878.

To all whom it may concern:

Be it known that we, IVILLIAM Tnonas Snrrrr and Ennnsr Ansnncnu, both of the village of East New York, town of New Lots, county of Kings, State of New York, have invented certain new and useful Improvements in Grain-Conveyors; and we hereby declare that the following is a full, clear, and exact description thereof.

The nature of our invention, in the first part, consists in an air-tight vessel or chamber, having on its upper portion a supplyvalve for the admission of grain conveyed thereto by means of exhausting the air conveyed in said air vessel or chamber, and suction pipe or hose connected therewith, and a number of exhausts on the lower portion of the chamber, in o"der to discharge the grain which has been formerly admitted to the same; and, in the second part, of a series of pneumaticvalres attached to diaphra gins, and operated by compressed air, for the purpose of regulating one and the other; and, in the third wart, to register the quantity and weight of the grain which has been elevated and transferred from one place to the other through the air-chamber.

Figure l in drawing represents a longitudinal vertical section of our invention. 2 is across-section of the diaphragm and valve. .laigs. 3 and :i show in detail the parts AA and l? B of Fig. 5 represents the external and sectional view of suctionpipe. Fig. 6 illustrates the exhaust-valves at the lower portion of the air-vessel. Fig. 7 represents a modification of the mode of opening and closing the valves at the upper and lower portion of the air-chamber,

A is an upright engine, to which the aircylinder attached, and operated by the crankomic *tion 0. On the fly-whecl D is r, E, attached, which operates the movement of the piston-rod a of der, I

also a or up-and-d in g, through the upward movement of its piston, the air-chamber G and the herewith-connected suction pipes Z) I), and through the downward movement of its piston to increase the discharge of the grain in the air-chamber G and the herewithconnected suction-pipes h I), throng the series of exhaust-valves c 0 into the funnel d, from which place the rain may be transferred to any point of the vessel or warehouse, as the case may be.

The cylinder F is so arranged as to produce by the downward movement of its piston, first, to close the supply-valves ff, and, second, to open the exhaust-valves c c of the chamber Gr The pipe II forms the connection between. the cylinder 13 and the chamber G.

The air-chamber G consists of two vesselsone outer casing, G, and the inner casing, G. The latter is suspended by means of strong elastic springs I from the top of the outer casing, G", and is properly guided through the rollers y y, attached to the inner casing, G.

In order to produce an effective air-tight chamber formed by the sidings of the inner casing, G, the exhaust-valves c 0, when closed, and the inner side of the upper portion of the outer casing, G, and yet to give a swinging motion to the inner chamber, G, the upper per tion of the said air-chamber G is lined with a rubber cloth, g g, (see Figs. 3 and 4,) in such a manner as to serve at the same time to keep suspended the inner casing, G, in common with the elastic spring I.

At that part where the air-pipe H enters the outer casing, G, a connection is made of rub ber hose or other suitable yielding material, which passes through the rubber clot-h g into the air-chamber G, thus effecting an air-tight compartment from the air-cylinder B hrough pipe H to air-chamber G.

On the one side of the suspended chamber Gis attached the pointer or indicator J, which follows the upward and downward motions of the casing G, and indents or registers on the horizontal lines of the unwinding paper o the register K the weight of each unit of quain "3, transferred into the air chamber whenever a vacuum. has been created and a quantity of grain has been admitted to the same.

The oscillator L, being an extension of flap-like valve 0 c and gearing on the cogwheel Z, causes to partly revolve the samei'or the space of one unit at each discharge of the grain. This revolving motion is transferred to the unwinding paper of the register K, thus causing the pointer or indicator to indent or register at the same time the uiantity {tilt weight of the transferred grain which passes through the air-chamber.

h is a deflector, protecting the mouth of the air-pipe ll.

The supply or suction pipes b are opened and closed by the valvesf f in such a way as 1 when compressed air has been admitted from the second air-cylinder, F, into the upper part of the diaphragm M, the same willbe brought downward, and the thereto-attached rod 1, operating on the two-arm lever 2', will shift the valve-stem K in the direction of arrow, as shown in the drawing, Fig. 1, in which case communication will be shut off between airchamber G and suction-hose b b.

In the upward motion of the piston of cylinder F, air is admitted to the lower portion of the diaphragm M, the rod l is pushed upward, the valve-stem K shifted in the opposite direction, and the valves f f opened.

Whenever the piston of cylinder B has performed its upward motion, and a vacuum created in the air-chamber G, and a unit of quantity. of grain transferred into the same, the next downstroke of both pistons of cylinder B and F will operate to discharge the grain in such a manner that, compressed -air from cylinder F entering through pipe m, the diaphragm M shall close valves f f, as described above, and open diaphragm-valve 0, passing through the same into pipe 19, and entering the lower part of diaphragm N, exhausting through vents o c to push upward the rod 1", and, by

means of the two-arm lever Sand circular connectingrod t, opens the exhaust-valve c 0,

through whichoperation the grain in the chamber G accumulated will, by its own gravity, discharge into funnel d.

.per portion of diaphragm N, push rod 1' down ward, and consequently close valves 0 c. It will open diaphragm-valve 0, and enter, through pipe 19, the lower part of diaphragm M, open the supply-valves f f, and exhaust through vents c o. I

The position of cranks O and E is such a one that crank E shall be slightly in advance of crank G, in order that the compressed air admitted from cylinder F, either through pipe m or it, shall have performed-the duty of opening and closing valves ff and c c, as the case may be before a vacuum is performed through the'upward stroke of piston of cylinder B. I I

The suction-hose b b, leading from the top .of air-chamberG to the place from where the grain or corn shall be elevated, is provided on its lower portion with a nozzle, 20, as shown in Fig. 5, having a number of openings to admit the easy entrance of the grain into the pipe I) 1).

Instead of operating the valves 0 c and f fby means of diaphragms, actuated .upon through compressed air from cylinders, adirect action I r from the upand downward movement of piston-rod G, as illustrated in Fig. 7, may be used in such ;a manner as that a guide, a. a, being firmly connected to C, will operate the continuation of valve-stems f and t. This guide a a has three vertical and two inclined sections, all connected with each other, forming one uninterrupted line, but broken in the direction of its section.

Theends of valve-stems f and t have an opening of slightly larger dimensions than the diameter of said guide a a, which is allowed to pass through the same. A downward movement of piston-rod G will slide sidewise both valve-stems and open and close the valves whenever the inclined section of a 60 passes through their end openings. During the time that the vertical section of a a passes through purposes as it may be adapted for, such as.

elevating quicksand, or mud, or other substances.

We claim- 1.- The arrangement of the apparatus for the elevation, measuring, and weighing of grain, or other similar substances, by the creation of a vacuum, as herein set forth. I

2. The arrangement for the automatically opening and closing of valves ff and c c by means of diaphragms actuated upon by com pressed air, as and for the purpose herein described.

' 3. In combination, with each other, the diaphragm M, diaphragm N, cylinder F, valves f f and 0 c, and service-pipes m and n, operated by compressed air, as shown and described.

4. The arrangement of the registering apparatus K, for the purpose of weighing, and measuring'the elevated material, as herein set forth. l

The inner air-chamber, G, the outer, G,

' the spring I,, rubber cloth'g g, and suction- .hose 1) b, in combination with registering apparatus K, as and for the purpose hereinset forth. 4

6. Thearrangement of cylinder B, pipe H, and air chamber G, and suction-hose b b,- for the purpose of alternating, receiving, and discharging-the elevated material, as herein set forth. 1
