APPARATUS FOR DETALGHIHG AND SEPARATING FIBERS FRGM COTTON-HULLS.
Specification of Letters Patent.
Patented J an. 3, 1911.,
Application filed April 15, 1809. I Serial NO. 489,981.
To all whom it may con-cam:
Be it known that I, EDWARD GARS'IENSEN DE Snoonoo, a subject of the King of Great Britain, residing at No. 231 Dash'wood House, New Broad street, in the city of London, England, hare invented a new and useful Improvement in Apparatus for Detaching and Separating Fibers from Cotton- Hulls, of which. the following is a specification.
The present invention relates to certain improvements on the structure disclosed in a co-pending application, Serial No. 119,942, filed March 9, 1908, and the primary objectgreater output and more efi'ective separating and segregating action,v while requiring less" power to operate.
In the machine disclosed in the aboveentitled application, vertical cylinder is employed having lower, combined air inlet openings, Which-also constitute outlets for the defibrated lmlls. Operating within the casin are centers that rotate on a verticai axis. Connected to the upper end of the casing is an uptake, towhich attached a suction fan that produces upward convergentstreanis of air within the casing from the lower inlet openings tothe uptake- Feeding means is connected to the upper portion of the and delivers the hulls to be ooereted on without admitting air at point. Briefly described when, the machine is in operation, and the upwardly moving currents of air are produced, the, heaters cause. a whirl of such air within said. casing, and the hulls operated on, are threshedby said heaters. As a result of the centrifugal force, the defibratecl-hul-ls locate-themselves against the inner walls of the casing, While the lighter material, such as the lint, 1s nearer the axis of rotation of the heaters. Now an important feature of this machine resides in.
thelfact that said heaters do not have any grindingaction, but i-ncrel-y thresh the hulls, and though said hulls are brokenup, they are so much heavier, than the lint that they gradually more downwardly against the in-"- ner Wall of the casing and pass through the bot-tom openings, while the lighter particles and"lint is carried upwardly b the .above described current of air, and
machine is entirely successful, but output discharge through the-uptake. The above descr bed comparatively limited, y because a stronger blast is put upon the uptake, some of the broken hulls will be carried out therewith. v
The principal object therefore of the present invention is to provide means, whereby such hulls are hindered from going upwardly, and will consequently more readily gravitate out of the lower end of the maehine. Atthe sanie time, the upward movement of the lint is not interfered with, and the result is a machine having a decidedly greater output.
In the drawings :--F igure 1 is a vertical longitudinal section through an improved machine constructed in accordance with the present invention. Fig. 2 is a side elevation of the same. F ig. 3 is a detail cross sectional View on the line 33 of Fig. 2. Fig. 4; is a detail cross sect tonal View on the line 4% of "Fig. 1..
Similar reference numerals designate corresponding. parts in all the figures of the drawings.-
In the embodiment disclosed, a cylindrical casing is enipioyed, designated generally by the reference numeral 1,-said casing co1uprising an upper sectioh 2, and a lower section, on which said upper section is mounted. The lower section comprises a bottom 6 having in its marginal portion a plurality of circular series of openings 7, which constitute air inlets and also outlets for the defihrated h-ulls. These openings are preferah-ly formed by cutting from the bottom, tongues 8 that are turned downwardly at an inclination, as fully described in the covpendii'ig application already referred to. The cylindrical wall of the lower section may, as disclosed, be made up of a plurality of rotatable'bars 9, that are triangular in crossseetion and carry at their upper ends, pin-ions ll engaged by a rotary gear ring 10.
It will be obvious that by rotating this ring, the. pinions'lljwill beturned-ahd' the bars 9 100 canconsequentlybe' disposed in difierent re-- latio'ns v Botatably mounted in the lower section of the casing are a plurality of 'beaters-;4i,' the ends oi said heaters being spaced-from the bars 9, and said heaters be- 105 ing carried-by a Vertical shaft 4: that can be "rotated Joy any suitable means. The upper end-of this shaft preferably carries a cap 49 that is in" the form. of a cone.
M ll/loomed. upon-'the lower sectioraasalready described jfl-isj the upper section '2, which, iscylindrical in form, and is provided rotated, the exhaust fan connected to the uptake is placed in operatiomand the hulls 16 to be defibrated, are fed to the interior of the casing, the said hulls will be given a threshing action by the heaters, and at the same time SlllDJQCtQCl to upwardly flowing currents of air from the openings 7 As already ex- 20 plained, the heavier hulls under centrifugal action, will assume outermost positions,
- against the bars 9, and will gradually move down said bars toward the openings 7, while the lighter fiber will be drawn upwardly by the currents of air into the uptake. If now the inlet openings are entirely closed by .the slmtters 5 and a heavy draft of air is produced. in the uptake, some of the broken hulls. particularly the smaller fragments will be drawn into said uptake. If, however, the shutters 5 are opened a predetermined degree, lateral currents of air will enter the casing and be caused to impinge against the upwardly flowing currents of air that are moving'to the uptake. Theintrusion of the lateral currents of air through the openings 3, upon the uprising spiral of the products, which have been detached from each other and which are to be sepa-- 40 rated or segregated, arrests the further uprising of'the hull particles and causes a deflection of the air currents, carrying'the lighter fiber,inwardly and upwardly toward the central uptake: Therefore the hulls will 5 not pass above the openings *3 into the up-' take, but will gravitate to the bottom ofthe casing, and finally escapethrough the openings 7. As a result, by properly adjusting the size of the openings 3 to the strength 5 of the exhaust, not only can the machine be run at higher speed with a-conscquent great increase in the output,"bu'tthere is not as much power required for the reason that the suction fan is not operating against as great a vacuum in the upperportion of the casing.
From the foregoing, it is thought-that the I construction, operation and many advantages of the herein described inyention will be apparent to those skilled in the art,- withoutfurther description, and it will lee-understood that various changes in the size, shape,
' proportion and minor details of construction, may be resorted'to without departing from the spirit or sacrificing any of the ad- 5 vantages of the invention.
