COTTONSEEDHULLDELINTING MACHINE.v

Specication ofLetters Patent.

Application filed June 2, 1916. Serial No. 101,329.

To all whom t may concern:

Be it known that I, TOM R. COLE, a citizen of the United States, residing at Rolf, in the county of Pontotoc and State of Oklahoma, have invented certain new and useful Improvements in Cotton-Seed-Hull-Delinting Machines of which the following is a specification.

delinting machines, and thevnature and objects thereof will be readily apparent toV those skilled in the art towhich it apper.

tains in the light of the following explanation of the accompanyingdrawings, illustrating what I now believe to be the pre abrading surface which is formed of diagonal perforations to remove the lint from the hulls in a complete and efficacious manner.V

Another object of the invention is to provide a cotton seed hull delinting machine having a drum, as mentioned above, and having an area of circular perforations through which the delinted hulls are ejectedY by means of rubbing surfaces movable in close relation to the perforated area.

In addition to the foregoing my invention comprehends improvements in the details of' construction and arrangementof parts to be' hereinafter described and particularly pointed out in the appended claims.

In the accompanying drawings in which similar and corresponding parts are designated by the same characters of reference throughout the several views in which they appear;

. been removed from the cotton-seed during.,`

Fig. 3, is a fragmentary view of a portionof the drum showing thecircular perforations, and

Fig. 4, is a similar view illustrating the diagonal perforations.

After the major portion of the fibers have their passage through the gin, ther-eis foundk to be a mass of'short fibers clinging tothe' hulls of the seeds which it is the object of thismachine to remove. These short fibers when removed and collected are used to a great extent inthe manufacture of nitrated cotton .for which purpose the material is" 1 j preferable to cottonhaving long fibers. This invention has relation to cotton-seed In machines of this type heretofore constructed the delinting process was slow and .tedious and consequently the quantity of lint. produced per `unit time was small, which made the cost of the operation of the ma- 1 chine necessarily high. I proposetherefore toprovide a machine capable of delinting a large quantity of hulls in a short time, owingr l to the provision of a novel form of abrad# ing surfacesy against which the hulls are thrown by centrifugal force and engaged by rubbing 'surfaces movable ata high rate of speed. f Y l...

With reference to the drawings 1 indicates an inner drum formed throughout its length with circumferential abrading formations 2, which abrading formations comprise diagonally disposed elongated perforations, parallel, and. extended in the same direction. As a result of these formations and the relation one to another, Ythe effect of thus forming the perforations is to define a number of broken, spiral grooves extended circumferentially of the drum andfrom end to end. The inner edges of the perforations are sharpened as at 4, and the objects thereof will be readily apparent as the description proceeds. Y l

An o uter drum 5 is provided for encompassing the inner drum to close the perforations therein, but is spaced from the discharge end of the inner drum, which discharge end is located at the right-hand side of the machine shown in Fig. 1. The circumferential area of the inner drum uncovered by the outer drum is provided with a plurality of circular perforations 6.

Plates' 7 and 8 are located at the head end and discharge end respectively of the drum' to form closures for the same to afford a support for the drum.` The platesY are centrally apertured to form bearings for the shaft 9 which extends longitudinally through the drum, and is also journaled at the discharge end of the drum in a bearing l0.l A pulley 11 is fixed to the shaft between the bearing l() and the end plate 8 whereby the .may be rotated, and a plurality of 'Patented Nov. 13, 17,9417. Y

collars 12 are fixed to the shaft, and correspond in number to the number of abrad Y ,terminals for engagement with internall threaded sockets in the collars 12, and the outer ends of the arms are formed with arcuate rubbing surfaces 14; which are disposed for rotation in close relation to the diagonal perforations. Thus it will be obvious that owing to the rotative adjustment afforded bv the provision of the threaded connection between the arms and the collars, the rubbing members 14 may be disposed at any desired angle with relation to the angle of the diagonal perforations soas to obtain various degrees of delinting effects.

A collar 15 is fixed to the shaft adjacent the discharge end of the drum and is formed with radial arms, an arcuate rubbing surface 16 is formed at the outer ends of the arms for movement in close relation to the circular perforated area of the drum for a purpose which will be presently obvious.

An opening 17 is provided at the head end of the drum and at the outer portion thereof for connection with a hopper 18 having journaled therein an agitator shaft 19 and an agitator 20 mounted upon said shaft. Pulleys 21 and 22 are'mounted for rotation upon the shafts 9 and 19 respectively and are connected for rot-ation in unison byV means of a belt 23.

An opening 24C is provided in the head plate 7 for establishing connection between the interior of the drum and the atmosphere, and the extent of said opening is controlled by means of a movable plate The end plate 8 is likewise formed with an opening 26 which is adapted to be placed in connection with some form of an exhausting or vacuum machine to create a draft of air through the drum, the volume of air fiowing through the drum being controllable by the plate 25 mentioned above.

ln operation t-he hulls are fed into the rhopper 18 from which they are discharged into the interior of the drum then having been set in motion, the hulls are then thrown against the inner surface of the drum by centrifugal force and abraded against the sharpened edges of the diagonal perforations owing to their' engagement between the surface of the drum and the surface of the rubbing members 14. The lint thus gradually and completely removed from the hulls. Owing to the spiral and diagonal relation of the perforations, the hulls are gradually conveyed toward the discharge end of the drum, and upon reaching the area of circular perforations they are projected or forced through said perforations by contact with the rubbing members 16 mounted for rotation in close relation to the said perforated area. During the operation of the machine the current of air passing through the drum conveys the particles of lint to a receptacle from which it is subsequently collected after a suflicient quantity has accumulated.

lt will be obvious that the delinting effect of the machine may be varied by adjusting the angle of the rubbing members '-t so as to provide a shearing action between the edge of the members and the sharpened edges of the perforations, and `the volume of air being passed through the drum may be likewise varied to correspond to the delinting of the machine and the speed at which the shaft is rotated.

Various ways of constructing my invention to employ the principles involved will occur to those skilled in the mechanical arts, and I therefore reserve the right and privilege of changing the form of the details of construction or otherwise altering the arrangement of parts Without departing from the spirit of the invention or the scope of the appended claims.

Having thus described my invention what l claim as new and desire to secure by Letters Patent is 1. A cotton-seed hull delinting machine including in combination a drum having an inner abrading surface, a feeding opening provided at one end of said drum, a plurality of perforations provided at the other end of the drum, a central longitudinal shaft journaled vfor rotation within the drum, rubbing surfaces movable with the shaft for co-actionwith the abrading sur faces, to abrade the lint from the hulls and to convey the Vdelinted hulls toward the perforated end of the drum, a plurality of arms mounted on the shaft for movement therewith adjacent said perforated end, arcuate members on the arm for movement in close relation to the perforated area of the drum to force the delinted hulls through said perfor-ations, means for rotating the shaft and means for creating a draft of air through the drum to remove the lint therefrom.

2.
