J. L. RUSHTON PNEUMATIC CONVEYER FOR COTTON AND SIMILAR MATERIALS Filed Sept..5, 192.

Patented Feb. 10, 1925.

- UNITED STATES Application filed September To all whom it may concern:

Be it known that I, JAMES LEVER RUSH- TON, a subject of the Kin of Great Britain, residing at Kay Street Works, Bolton, in the county of Lancaster, England, have invented new and useful Improvements in Pneumatic Conveyors for Cotton and Similar Materials, of which the following is a specification.

The invention relates to improvements in or relating to pneumatic conveyers for cotton and similar materials.

In pneumatic conveyers the cotton or the like is usually sucked through a pipe or tube to its destination by means of a fan and in practice it is found that foreign matter such as nails, rivets, binders or the like are car ried with the material under treatment and where the cotton or the like is destined to pass into a machine for treating the cotton or the like serious damage may be caused to said machine by reason of the presence of said foreign matter.

Now the object of the present invention is to provide a penumatic conveyer for fibrous materials such as cotton with means whereby any foreign matter will be trapped and prevented from passing out of the conveyer into a machine or otherwise.

In the accompanying drawings- Figure 1 is a section of a portion of a pneumatic conveyer tube constructed ac cording to the present invention.

Figure 2 is a side view thereof and Figure 3 is an end view thereof.

Referring to the drawings, the conveyor tube is interrupted at one portion thereof and is preferably provided at said interrupted portion with a flat bottom 3, whereby an outlet opening t is formed in the wall of the tube, one wall of said outlet opening forming a lip or blade extending into the tube in a direction opposed to the normal direction of travel of material through said tube. Attached to the tube in such position as to enclose the outlet opening 4: is a box 2 having an inclined bottom 2, the highest portion of which engages the underside of the end '5 of the flat bottom portion 3.

From the foregoing it will be seen that when material under treatment, such as cotton, is passed through the conveyer tube,

JAMES LEVER RUSHTON, OF BOLTON, ENGLAND.

PNEUMATIC CONVEYER FOR COTTON AND SIMILAR MATERIALS.

5, 1923. Serial No. 660,986.

any foreign matter that is heavier than cot-ton will sink to the bottom of the tube and will travel along the Hat portion 3 until it reaches the opening 4. Its momentum will carry it through said opening until it reaches the point 5, whereupon, owing to the inclination of the bottom 2 of the box, such foreign matter will be trapped,

so that it cannot return to the conveyer tube.

The box 2 may be provided with a sliding or other door 6 through which the foreign matter trapped in the box 2 may be re moved therefrom and the opening 4 may be provided with an adjustable slide 7 so that said opening may be regulated according to the class of material passing through the apparatus which may be regulated as desired while the details of construction of the device may be modified without departing from the principle of the invention.

What I claim as my invention and desire to secure by Letters Patent is 1. A conveyer tube having at one side thereof a lip extending within the tube in a direction opposed to the normal direction of travel of material through said tube and a lip extending outside of the tube, said lips forming between them an outlet opening from the tube, and a normally closed box enclosing said outlet.

2. A conveyer tube having at one side thereof a lip extending within the tube in a direction opposed to the normal direction of travel of material through said tube and a lip extending outside of the tube, said lips forming between them an outlet opening from the tube, and anormally closed box enclosing said outlet, said box being provided with an inclined bottom.

8. A oonveyer tube having at one side thereof a lip extending within the tube in a direction opposed to the normal direction of travel of material through said tube and a lip extending outside of the tube, said lips forming between them an outlet opening from the tube, a normally closed box enclosing said outlet, and a slidable member for adjusting the width of said outlet opening.

I11 testimony whereof I have signed my name to this specification.

JAMES LEVER RUSI-ITON.
