' cmmeareme- To all whomz't may concern:

Be it known that we, GEORGE WHITIAKER- HAneRnAvEs, ALBERT I-IARennAvEs, and ROB-- ERT HARGREAVES, all sub ectsof the Klng of Great Britain, residing at Brookhouse Lane,

Blackburn, inthe county of Lancaster, Eng-1 land, have invented certain new and useful Improvements in CardingEngines,iofwhich the following isa specification;

This invention relates-to carding engines and has for its chief object'to provide an improved arrangement-for simplifying and facilitating the stripping; cleaning and .qgrinding operations which will dispense with :the necessity forltransferringithe stripping thrush. from the cylinder to the dofli'erto perforinthe stripping *operationsand. in like manner the grinding roller from the cylinder toithe v operation thereby reducing labor.

According to this invention means are i provided for detachably mounting :thestripping brush in the throat formed by the r dofie or cylinder andfor moving same into i .25

'onthe dofi'er and cylinder for stripping pur-- v poses and for raising such brush out IOIllCOIl .contactvwith the .wire ofthe (card clothing tact therewith afterfthe stripping operation has been eflected or for cleaningpurposes,

the said brush being advantageously inclosed 7 within an air tight or c-losely fitting casing adapted to be connectedlwith an air suctionplant for dust removing purposes.

to. Eachof these end frames has a curved. outer portionuof a somewhat larger radius than, that of the stripping brush and the frames are formed .with slots 01 for the in-- sertion andremoval. of thebrush spindle a, slides (i being employed to close the greater portion of said slots but leave a space d doifer to perform the grinding and casing in. accordance with this inven Specification of Letters Patent.

for the lifting and lowering movement of the splndle. The latter is conveniently supported at its end in a bearing a formed in a slide or armo thatis slidable in a bracket of whlch is ad ustably mounted on one of the exlstlng cylinder blocks 5 Each slide or frames and is "fitted with one or more handles a for turning purposes, the arrangement being such that when the handle is "turned? in one direction the eccentrics lower :tlieslides or arms a? to 'bring the stripping brush into simultaneous engagement with the 'cardw -re of the/cylinder andthe dofier,

*and when turned 'in they other direction raise thestripping brush clear of such wire. To

. cause the stripping brushEto engage equally 'wlththe wire onthecylinder and dolferpthe slide, or arm at is made extensible at a and provided; with screw adjustment a and the bracket which carries such arm is slidable on the cylinder block b fo moving the strippin brush .A= itow ard the cylinder 0r doffer as :may;befrequired; said movement being conveniently effected by an adj usting screw 6 The space between the end frames is coveredv bythe cylinder anddofler plates dtctywith the exception of an aperture'ol which is large enough to admit a cylindrical 'memberwhich may be either the stripping brush or a grindingrrollersubstituted therefor, and. is normally-closed by a curved door (Z which fits closely over the end frame and along thea'djacent edges of the cover plates 1 i di fo This door is advantageously hinged Fig.2 is a front'view .ofone'endoithe.

apparatus, and Fig.3 is an end view -ofthe along itslower edge to the adjacent plate and a. convenient method of cleaning the stripping brush comprises .a comb a which maybe hinged coaxiallywith the door, and

adapted to swing independently of the door, ;so thatthe comb may bemoved into contact with the brush for cleaning purposes when the door is opened. i y 1: ,By thearrangement described all that is necessary'toperform the stripping operation islto turnthe handle a to lower the brush ,into. thewireo-fthe dofl'er and cylinder and plutthe rope or belt onto the pulley onthe strippingbrush spindle, one of such pulleys being-conveniently mountedyat each end of the spindle- When the stripping operation is completed the brushis raised out of the wire and if it is desired to clean it thedoor is opened and the brush turned in the opposite direction so that the backs of the wire run in contact with the strippin comb, and as the latter is situated at the juncture of the hinge the material from the. brush is transferred onto the open door. To effect the grinding operation the brush is removed and a grinding roller substituted therefor, any adjustments that may be required being effected by the adjusting screws on the arms and brackets previously described. The cover plate or end frame is advantageously fitted with a pipe connection d (Fig. 3) so that if it is desired to use the apparatus in conjunction with a suctiondust removing plant it only becomes necessary to connect a flexible or other pipe with the aforesaid pipe connection, the cover plate and end frames being constructed to make as tight a fit as is practicable with the adjacent stationary and moving parts of the carding engine.

. Thewires of the stripping roller A are inclined forward in the direction of rotation of the roller as shown by dotted lines in Fig. 1, and are made of suflicient length to enable them to act as hooks which remove fiber simultaneously from the cylinder B and dofl'er C, and retain the fiber until it isremoved bythe comb a Heretofore, the stripping roller or brush has been used first to strip one of the members A, C, and then transferred to the other member to strip the latter.

What we claim as our invention' and desire to secure by Letters Patent in the United States is:-

1. In stripping brush apparatus for a carding engine having a doffer and a cylinder forming a throat, a cylindrical stripping brush, means for 'adjustably mounting the stripping brush in said throat, and means for moving such brush into and out of simultaneous contact with the carding surfaces of the d-ofi'er and cylinder.
