VALVE-DISCHARGE.

Specification of Letters Patent. Application filed April 2. 1907. Serial No- 366.031.

Patented Dec. 24, 1907. e

To all whom it may concern:

Bl: it known that I, WILLIAM E. ETH- RIDGE, citizen of the United States, residing ,at Schlater, in the county of Leflore and State of Mississippi, have invented certain new and useful Improvements in Valve-Discharges, of which the following is a specification.

This invention relatesto means for preventingback current of pneumatic conve er for discharging material of any kind an is particularly adapted for the pneumatic disi charge of cotton gins and mills.

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction an the means for effecting the result, reference is to be had to the following description and accom anying drawings.-

VVhi e the invention may be adapted to different forms and conditions by changes in the structure and minor details without departing from the spirit or essential features thereof, still the. preferred embodiment is shown in the accompanying drawings, in which:

Figure 1 is asidevview of a pneumatic discharge or conveyer provided with a valve Fig. 2 is a sec-- embodying the invention. tional view of the valve showing the parts on a larger scale. Fig. 3 isa sectional view of the valve on the liner-11: of Fig. 2. Fig. 4'is a modification showing. the spiral flight ofthe feeder meshing with the blades of the ro- 138.18 valve. y

orresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The numeral 1 indicates the neumatic discharge which may be either oft e blast or suction type, the valve being of special advantage in'connection with a blast discharge since it prevents the air ressure affecting the delivery of the material to the discharge for conveyance thereby to the required point.

The pneumatic discharge may conslst of a pipe duct or conveyer of any type such as commonly employed for directing material to the required point of deliver A fan blower 2 is connected with the dlscharge 1 and creates a current therethrough for mov ing thematerial to the end thereof. At the point of delivery of the material to the discharge 1, is located the valve which is of such construction as to prevent any back current,

An apron 7 is adapted to bear againstthe rotary valve ata point about opposite to the rounded part 6 of the. box or pneumatic conveyor passing by the valve pivoted at its uppbr end and is pressed towards thevalv at its lower end by means of a sprin 8 which may be of any type. The ends 0 the valve fit the sides of the box or casing 5 close to prevent air passing thereby into the feeder.

' The valve in operation is rotated so that its 11 per portion travelstowards the apron 7 and by having the latter spring actuated for yielding, it may move to permit any material-to pass which would otherwlse lodge between the rota .valve and apron and either producebind ing or tend to displace or strain the mechanism. Thefeeder" 9 may receive the material to be delivered to the pneumatic 'conveyer or discharge 1. The valve is interposed between the feeder and discharge and receives the material from the feeder and delivers the same into the pneumatic discharge. In cotton gin machinery, the feeder 9 may be the seed conveyer box into which the seed from .the gins are delivered and conveyed thereby to" the pneumatic discharge. A spiral or auger conthe material is delivered to the valve and by mto the feeder. .The apron-7 1s hinged or The rotary valve may.

- stances t e construction shown in Fig. 4, 'i. e.,

by having the flight ofthe conveyer 10 enage with the bla es of the rotary valve may be preferred, thereby economizing space and greatly simplifyin the construction. 4

Havin thus escribed the invention, What is c aimed as new is:

1. In combination, a pneumatic discharge, a feeder, a rotary valve located intermediate the feeder and pneumatic discharge, and a spring actuated apron held in contact with rounded bottom portion of the same, and a spring actuated apron in contact with the valve at a oint opposite to the rounded portion of t 1e box, thereby preventing air from the pneumatic discharge finding its way into the feeder and insuring positive and regular discharge of the feeder into the pneumatic conveyer.

In testimony whereof I affix my signature in presence of two witnesses.
