PNEUMATlC-CONVEYER VALVE.

SPECIFICATION forming part of Letters Patent No. 683,666, dated October 1, 1901.

Application filed April 29,1901.

said castings. The threaded portions of said To all whom, it may concern:

Be it known that I, GRANT S. SHANNON, a citizen of the United States, residing at Houston,in the county of Harris and State of Texas, have invented certain new and useful Improvements in Pneumatic-Oonveyer Valves; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to pneumatic-conveyer valves for gin-feeders.

The object of my invention is to providea valve which will form between several independent intake or outlet ports and the main convcyer-pipe a continuous direct pipe-line with minimum bend or curve and free from internal switch-plates or other means which obstruct or reduce the capacity of the valve.

It is also my object to provide a valve which will serve as both a receiving medium from several sources of supply and also as a delivery medium to separate depositoriesthat is, my valve will serve in a pneumatic ginfeeder as both a receiving medium to connect the main convcyer-pipe directly with a loaded wagon or to a warehouse stored with seed-cotton or as a discharge medium after the seed-cotton is ginned to connect the main conveyer-pipe with a seed-cotton bin and cotton-seed bin.

In the accompanying drawings, forming a part of this specification, Figure 1 is a top plan view showing the valve-cage in full lines in one position and the valve in dotted lines when shifted. Fig. 2 is a longitudinal ver tical section of the valve and cage, and Fig. 3 is a detail View.

Reference being had to the drawings, A denotes a casting containing ports a a. a a denote collars formed integral with said casting projecting outwardly around said ports and are designed to connect the conveyorpipes leading from the warehouse or other depository to the valve.

0 O O 0 denote rods connecting the casting A with a casting D. The ends of said rods are screw-threaded and pass through perforations in the lugs a and d, formed on Serial No. 57,955. (No model.)

rods are provided with adjusting-nuts c.

The castings A and D and rods 0 form together the valve cage. The casting D is formed with a central port having a collar d projecting at each side formed integral with the casting. The outer or free end of said collar is designed to connect the main conveyorpipe, (not shown,) leading to the gin-room, while the inner end enters the Valve. The valve consists of a pipe E, inclosed in said cage between said castings A and D,and is clamped in position by the nuts 0 on the connectingrods. The inner end of said pipe is mounted pivotally on the casting D, said end fitting over the collar cl and provided with a flange 6, which bears and turns freely on the inner face of this casting. E denotes an oblique offset in the pipe E, which causes the outer end of the pipe as its position is shifted to move in the arc of a circle described from its inner pivotedfend. 6 denotes a handle for operating said valve.

F denotes a casting having a collar formed therein, which fits around and inside of the walls of the outer end of the pipe E and is adapted to slide over the inner face of the casting A in an arc of a circle described from its pivotal connection.

f denotes a threaded bolt to which the collar F is pivoted. Said bolt passes through said collar and through the casting A at a point in the axial plane of the port in the casting D. f denotes an adjusting-nut for said collar.

I have shown the casting A with two ports; but it is evident that additional ports may be added by increasing the width of the casting and adding ports in the arc.

To change the source of supply from a wagon-load of seed-cotton to the seed-cotton stored in a warehouse, the outer end of the pipe E is shifted by hand or by automatic de vices from one port in the casting A to the other. After the seed-cotton thusdirected to the gin-room is ginned the seed can likewise be directed to the warehouse or to a wagon. In either event my valve serves as a medium for forming with the main conveyerpipe a continuous pipe-line with but a minimum deviation from a straight line, of pipe and avoids the use of switch-plates or other impediment to the free passage of goods through the valve.

My purpose in connecting the castings A and D by adjustable connecting-rods is to insure as near as possible a snug joint between the collar F and the ports in the casting A.

Having shown and described my invention, what I claim, and desire to secure by Letters Patent, is

1. In a pneumatic valve for conveyer-pipes, the combination with the pivoted valve-pipe having an offset therein, of the valve-cage having castings at each end adj ustably connected by tie-rods one of said castings serving as a union for the pivoted connection of said valve-pipe to the main conveyer-pipe while the other casting is provided with aseries of ports which serve as unions for branch conveyer-pipes.

2. In a pneumatic conveyer, the combination with the main conveyer-pipe and a valvepipe pivotally connected thereto and having an oliset therein, of the valve-cage having castings at each end, means for connecting .said castings and clamping the valve-pipe
