IMPROVEMENT IN DOUBLE-ACTINGl-VALVE CUT-OFFS T0 FLOUR-PACKERS.

Specication forming part of Letters Patent N0. 168,020, dated September 21, 1875; application filed March 3o, 1875.

To all whom it may concern:

Beit known that 1,AUGUsTrN M. HoBBs, of Waupaca, Waupaca county, State of Wisconsin, have inventeda Double-Acting-Valve,

au gers that before the tubeB can be changedwhich often has to be done in the Eureka Hour-packer many times in a dayit re'- quires two men with heavy iron bars to climb a ladder to the ceiling' before the cut-off V can be closed, and which, when closed, leaves ten barrels of flour between tube B and cutoff V, which has to be drawn off before the tube B can be removed, which takes time, and is universally inconvenient and troublesome.

ln carrying' out my invention, the doubleacting-valve cut-off, which is at C in Fig. l, being so low down, completely does away with the inconvenience and trouble so much experienced With cut-offs in flour-packers, and especially the cut-off in the Eureka Hourpacker, which is at V in Fig. l. Besides, the double-acting-valve cut-oli' at O in Fig. 1 is so constructed and applied to flour-packers, and especially to the Eureka Hour-packer, that one person standing on the door beside the tube B can, with one hand, by means of a lever, which is at D in Fig. 1, close the cut- 'off at (l, thereby stopping thel flow of our into said tube B, and which only leaves, after said cut-ofil at C is closed, about one half barrel of flour between the tube at B and the cut-off at C, where, as before, in the Eureka flour-packer, it left ten barrels between the tube B and the cut-off at V, as in Fig. l,

- thereby completely overcoming the inconvenience and trouble so much experienced by using the cut-off at V in the Eureka flourpacker.

The valves of my cut-off, which are E and F, are so constructed that they are entirely independent of each other, so that when the lever D is in a horizontal position, as represented in Fig. 2, the lower valve E is opened, while the upper valve F remains entirely closed, thereby regulating the ow of our into the tube B, to suit the convenience of the operator of the machine. Besides, when the lower valve is open the pressure on the upper valve F is so diminished that it can be opened without difficulty, and when the valves are both opened they are perpendicular, as shown in Figs. l and 3, and in no Way impede the progress of the our into tube B, as represented in Fig. l.

lt is evident that the cut-off may be provided With a lever at each end for operating` Y the sam e.

In closing my cut-o the upper valve F a manner makes my cut-oli' and the other rods much stronger and more durable, which makes my machine far preferable to any now in use, the valves working independently, being silnple of construction, durable., easily worked, and not liable to get out of order.

I claim as my invention- Tube C, having independent valves E, and if secured to shafts provided with cogged segments separately engaging with and operated by lever D, as and for the purpose specifled.
