LEONARD JOHNSON, or NORTHAMPTQN, MASSACHUSETTS, ASSIGNoR To oTTo A. i BELGER, or NEWTONVILLE, MASSACHUSETTS. Y
T o all whom #may concern.
Be it known that lI, LEONARD JOHNSON,
a citizen of the United States, residing at Northampton, 'county of Hampshire, State of Massachusetts, have invented an Improvement in Waste-Collectors forCombing-Machines, ofwhichv the following Vdescription, in connection withthe 'accompany'- ing drawing, is a specification, like characters' 0n f the drawing representing like pa A This Ainvention relates to combing vmachines and particularly to combing machines which are provided with a waste collector of the general type shown in United States patentto Roth, ilo, 905,288, dated December 1, 1908, or United States patent to Belger, No. 1,106,073, dated August 4, 1914. The waste collectors Shown 1nv these patents comprise a casing which incloses the combing member and the stripping member, an air-exhausting mechanism for creating an air current through the casing which takes the' waste Ioff yfromv theY stripping member, a rotary rperforated screen situated within the casing adjacent the exit end thereof vand arrangedsothat the air current passes through the Screen whereby the waste is drawn onto the screen, and a stationary shieldl within the screen which Vprotects a portion ,of the periphery thereof from'the action of the air-exhausting device with thel result that the vwaste which is drawn onto that portion of the perforated screen'. through which the air current is passing will lbe carried by the rotation of the screen around to that portion thereof which is protected from the air current from which it is removed and drops into a can or other similar receptacle Suitably placed forjthis purpose.
In the 'operationi of. waste` collectors of this'type thewasteusually is removed from the screen in the form of a fleece or Sliver and being of a fluffy nature it will pile' up more or less rapidly in the can or receptacle. As a result, it is necessary *forl the attendant to packthis waste down in to the can by hand in order to prevent it 4froml running over the ltop 'of the can'. This 'operation of manuallypacking the waste into the can as it accumulates is not always at tendedto faithfully bythe attendant with the resultthat frequentlythe can becomes WASTEcoILEcToR TOR CoMBINS-MACHINES.V

filled and then the waste will drop over the top of the can onto the floor. Y
The object of my present invention is to provide a novel device for automatically packing the waste into the'can as it is delivered from the screen, which device not onl prevents the possibility of the loose ilu y Waste overliowing the can, but also packs the waste more firmly than would ordinarily be done by hand, thus requiring less frequentattention So far as emptying the lcan is concerned. In order to lgive an understanding of my invention, I have illustrated in the drawings a selected embodiment thereof which will now be described, after which the novel features will be pointed out in the appended claims. The figure illustrates a portion of a combing machine having my improvement applied thereto.
ince my present invention relates simply to the waste collector and the means for packing the waste into the can or receptacle,l` have not deemed it necessary to illustrate a complete combing machine, but have contented myselfwith showing only asuiiicient lportion of a combing machine and its waste collector to enable my invention to be understood. i A
' 1 indicates a portion of the frame of a combing machine,'2 indicates the combing member' and Y3 the stripper brush by which the waste iS stripped from the combing member during the operation of the machine. These parts are or may be all as usual in combing machines and form no part of my present invention. Y
Associated with 'the- Vcomber and the stripper is a waste collector having aconstruction Somewhat Similar to that illustrated Vin Patent No. 905,283, dated December 1, 1908, in that it comprises a casing 4 which incloses the combing member and the kstripper brush, an air-exhaust apparatus or fan 5 which is connected to the casing by a pipey or conduit 6, and a perforated rotary screen 7 situated adjacent the exit end per. Tlviez'bicurrent of air thus established throiggn'ztthe casing l will draw the Waste from the stripper, as indicated at 9, and thfiwastepwill be deposited on the portion of the screen Which is exposed by the shield and through which the air current passes. As the screen rotates the Waste which is accumulated thereon is carried under a com- Vplesfflgiroll 10 and over the portion of the screen Which is protected by the shield and which is not subjected to the action of the -forciiig device. This Waste which is 'onrthe protected portion of thev screen is "i "il I. 15| The which is taken off from the` screen u L; more or less light and uify o: dition aid ,it will, therefore, build up rat"erliapiI lyI in the can 11. As stated above, it, has heretofore been the common p'iiacticeffrfthe attendant to periodically f z: ifi m f 'mi pack the Waste 'into the can by hand in order to preveiittheivaste from ruiming over the tgip lofthe', caiiill," In accordance with my inveiitiin''prlfse to employ a waste-packing n i1-iw vi.; rollyvhicA lis yieldingly held 1n contact with tliebtvatintt'iscrden at about the point Where tfefvs'f oved from the screen and yyuii hiivgil'lgtigpqtated With the screen. This iia-Ie-rpaczlringiroll serves to automatically pack the-ivasteiiito the can When thev can beponpes filled and it will operate to apply suf- E eifitm'iessufto the Waste so that the lathep'aclld into the can more firmly thaiitis iisu', jiydcine by hand, thus prolongiiigtllf'timzewhich may elapse before it is ,iiitessiirygto "empty the can. This Wastepclitiii0iifro-llis"1l indicated at 12 and is iii the tiinibta cylindlei which is shown as snitabhly su portedi'irbrackets 13 carried by the filainefof tliefiiiachine. Suitable means are l'iiiidedzgfdiiyibltlingly holding the packcaii'fb iieii'ieifitly'be done by making the ldrfckets 1 nfitlimtlie inclined slots 14 in itlgtblymounted the bearings 15 to?thefshdftloithe roll 12 and providing tblespriifgsl1Z-vvliich tend to force the dri'i'igswdbfiitiliv'aiidly in the slots thereby hldiiiigtli Iiacking roll 12 yieldingly aggjaiirst,fthfe screen Any ,other suitable nieaiisiib ,itliiisliolding the roll yieldingly efi'taifyffscreen may be provided iiut'fdpaiti'ig from the invention.
iill'lil may be rotated either fm1 vi i; .wim il by t'iictional contact with the screen 7 or may be positively driven as desired. T it is to be positively driven, any suitable means for this purpose may be employed, such, for instance, as gears which connect it to the rotary screen.
With this arrangement the Waste collector Will operate all as shown in said patent until the light luii'y Waste mass in the can 11 is built up to the top of the can. At this 7 time the combined action of the packing roll 12 and rotary screen 7 will operate to force the Waste into the can as it is delivered from the screen, thus preventiiig` the Waste from spilling overl the top of the can. This positive feeding of the Waste into the can by the packing roll 12 will compressthe iWaste in the can 11. I find from demonstration-that with the packing roll 12 it ispo'ssible to pack forty or fifty per cent.V more Wasteinto the can than is usually done bythe handmethod.V
The use of this packing roll has theadvantage that it requires no attention on'the part of the attendant. Consequently,y since the attendant is relieved from the necessity of frequently packing the Waste intel-the can by hand to prevent its ruiming over, he Scan devote his entire time to the supervision .of the machine and is thus'able to look after more machines than is possible Where a part of his time is necessary in packing the waste into the canby hand.
All danger of the WasteV spilling over onto the Hoor is thus avoided and this is. an advantage because the Waste ywhich,does, thus ings and at a considerable loss. y V
