PICKEB. FOR COTTON LINT.

Specification of Letters Patent.

Patented Jan. 5, 1915.

Application filed May 28, 1913. Serial No. 770,357.

To all whom it may concern:

Be it known that I, IVAR MEURLING, a subject of the Crown of Sweden, but hav ng announced my intention of becom ng a citizen of the United States of Amerlca, and a resident of Brooklyn, county of Kings, and State of New York, have invented certam new and useful Improvements in Pickers for Cotton Lint, of which the followmg 1s a specification, reference being had to the accompanying drawings, forming a part thereof.

This invention relates to an improvement in pickers for cotton lint.

The object of the invention is to provlde a picker for seeded cotton without heaters by utilizing an air blast to separate the fibers.

I will describe my invention in the following specification and point out the novel features thereof in the appended claims.

In the accompanying drawings; Flgure 1 is a sectional side elevation of an illustrative embodiment of the invention. Fig. 2 is a fragmentary vertical section, on an en larged scale, of the air blast mouth piece and adjacent feeding mechanism.

As illustrated in the drawings the invention is applied to a standard picker of well known construction comprising a pair of side frames 10 at the one end of which a horizontal feed apron 12 is mounted on rollers 14. The seeded cotton lint 15 is carried by said apron to a feed roll 16 which cooperates with an adjustable hinged plate 18. This plate 18 acts upon an evener 20, the details of which are not shown as this forms no part of my invention. The lint passes between the roll 16 and plate 18 to the feed rolls 21, 22, from whence it passes into the path of the air blast by which it is separated and also freed from dirt.

23 is a fixed plate the upper edge of which is close to the surface of the roll 21 and is provided for the purpose of preventing the lint which is blown against roll 21 from sticking to it.

The air blast is supplied by a fan or blower 24 mounted on a bridge 26 located and clamped between the extensions 27 of the side frames 10. The blower is driven by a belt 23 passing over a pulley 25 on a counter shaft 29, said countershaft also driving a belt 31 which drives the shaft 35. The air from the blower passes through a pipe 28 connected therewith and provided at its lower end with a discharge nozzle or mouth piece 30. The air blast is discharged from the mouthpiece 30 in front of the feed rolls 21, 22 and against a deflecting plate 82. The latter is hinged and adjusted by means of a screw 3 to regulate and direct the air blast.

The cotton is blown apart and conveyed by the air blast under a removable hood 34 which is located above a screen 36, the latter forming the top of an air tight dust box 38. At the bottom of the dust box 38 is a rotary valve 39, which may be rotated to allow the dirt and dross which collects in the box 38 to drop out. The rotary valve prevents the escape of air from the dust box when dirt is being removed therefrom. The air current generated by the fan strikes the cotton throwing the latter against and dragging it over the curved screen 36. The dust and dirt will pass through the screen into the dust chamber, and from there it will be deposited on the floor beneath the picker by the rotary valve at the bottom of the dust chamber. The cotton is then blown to an enlarged chamber 40 at the entrance to which is a grid 42 over which the cotton passes. Then the cotton comes under the influence of the picker suction fan 44 which communicates with the rotary condenser screens 45 and 46, and by the suction of said fan the cotton is drawn onto said condenser screens. From the condenser screens the cotton lint passes through various sets of feed rolls 48, 49 and 50 to the lap rolls 52 where it is rolled up in the form of a lap 54.

By the construction above set forth it will be noted that the cotton lint fibers are thoroughly separated by the air blast but are not injured as is the case with the customary heaters and consequently the fibers are not broken. The fire risk is reduced to a minimum and the laps are cleaner and the yarn is stronger as a result of the operation of the device.

What I claim is:

1. A. lint cotton picker, comprising a screen, an air blast, means for feeding the cotton into the path of said blast whereby the former is blown over said screen, means for adjusting the direction of said blast, a dust chamber below said screen, a rotary valve at the bottom of said chamber, in

' combination with a receiving chamber pro-.

vided with rotary condenser screens, and means for forming the lint into a lap roll.

2. A lint cotton picker, comprising a shield, a screen below said shield,-a blower,

means for delivering a blast of air between S 2Lld*'Sl11'eld' and screen, means for feeding:

cotton lint into the path of the air blast,

means for regulating and deflecting said blast, a dust collecting chamber below said screen; a rotary yalve" in" the bottom of said: chamber, and means for condensing the lint'ajndr formingfit'j into a lap.

3. A lint cotton picker, comprising a frame,- a" shield conve'Xed, downwardly, a screen substantially parallel t'o said shield and forming the top of a dust chamber, a fan mounted on said frame, means for con veying'fa blast of'air from said: fan to the spaee' beti'v'een said shield and screen, vad'- ju'sta-ble means for deflecting and regulating the discharge of said air blast, means for feeding lint into the path of said air blast, and means for condensing the lint and forming it into a lap.

4;. A lintcotton picker, comprising a shield, a screen forming an air passage with said shield, means for supplying a; blast of air under pressure at the entrance of said passage, a'h-inged plate for deflecting the current of air, means for adjusting said plate, means for feeding lint to the air passage, and means for condensing the lint after it is discharged from said passage.

In Witnesswhereof, I have-hereunto set my han'd this' 27 day of May in the year 1913.

IVAR MEURLING.
