HORACE VVOODMAN, OF SACO, MAINE.

Specification forming part of Letters Patent No. 15,313, dated Jnlyl, 1856; Reissue No. 2,202, dated March 13, 1866.

T0 all whom it may concern:

Be it known that I, HORACE WooDMAN, now of Saco, but formerly of Biddeford, in the county of York and State of Maine, have invented Improved Machinery for Cleaning` the Top Cards of Cardin g-Engines; and I do hereby declare that the same is fully described and represented in the following specification and the accompanying drawings, letters, gures, and references thereof, making a part of the specification.

My said-invention relates to -mechanism for moving the cleansing-frame forward and backward from one top card to another; to mechanism for holding the cleansing-frame flrml y in place wh ile the top cards are raised, cleaned, and restored to their seats; to mechanism for changing the position of the cleansing-frame relatively to the top cards, for the purpose of cleaning different series of top cards; to meehanism for giving the motions to the devices used for raising, cleaning, and restoring the top cards, and to mechanism for removing the waste from the cleaning-bar.

The nature of my invention will loe more fully understood by the following description and recital, reference being had to the annexed drawings. I

Of the said drawings, Figure 1 denotes a top view of the carding-machine provided with my improvement. Fig. 2 is an elevation of that end of it called the driving end," or the end to which the driving-power is applied to the card. Fig. 3 is an elevation of the opposite end, to which the drivin g-power is applied to my cleansing or stripping machinery. Fig. 4 is a rear elevation. Fig. '5 is a transverse section of it, giving a central orinside view of -parts of my improvement in connection with and partially obstructed by the arch of top cards.

Other figures, representing detached, parts of my improvement, are given in my drawings, and will be hereinafter referred to and described in giving a full delineation of the machine.

In the first place, A represents the main frame of the carding-machine, whileB B B denote a series of top cards thereof, each of which cards is composed of a bar or lug, 13,'

having a strip of card lleting or teeth thereon, fixed on its under surface in the usual manner. The main card-cylinder is shown at C, many of the remaining well-known working parts of the carding-inachine not being` represented in the drawings, they having no special reference to my improvement, being such as are in general use.

I make use of two arms, a and a', and a cross-connection bar, d. These form a frame which may be called the cleansing-frame,77 which is made to extend upward or outward from and turn freely on the boxes of the main shaft E of cylinder C, the two arms a and a' being placed outside the cylinder, as is seen in Figs. 1,2, 3, and 4L of the drawings. The form and parts of arms a aud a' are most plainly seen in Figs. 6, 7, 8, 9, 10,11 of the drawings, where they are represented in connection with some other parts of my improvement, Fig. 6 representing an end or outside view, Fig. 7 a sideor cross view, and Fig. S a central or inside view, of arm a' and such other connected parts -as are given in said figures, and Figs. 9, 10, and 1l. representing the same series of views of arm a and such other parts as are given in connection in either of said figures. There are sustained in suitable bearings in arms a and a' (which bearings are seen in said Figs. G to 11) shafts H, H',and H2, which are connected together by bevel-gears, as seen in the full drawings, and which shafts turn freely in said bearings. Stand e, a top view of which is given in Fig. 24, and an end view in Fig. 25, is affixed to the end of the card-frame which is the driving end of my top-card-cleaning devices by means of bolts. Said stand supports a stud, the axis of which is on a line with the axis of the cylinder-shaft. There is Aplaced on this stud a bevel-gear, I?, and driving-pulley P', which turns freely on said stud. Said bevel-gear P engages with two smaller bevel-gears, Q and Q', which turn freely on said shaft H. There is placed on shaft H, between gears Q and Q', a clutch, N, said clutch sliding freely on said shaft in the space between said gears Q and Q'. Said clutch is attached to said shaft F by means of a spline, W, embedded in said shaft,

and fitting a groove cut in the hollow bearing of said clutch, as seen in Fig. 19 of the drawings, which gives a central and longitudinal section of said pulley, vI'Jevelgears, clutch, spline, and portion of shaft H. The said clutch is provided with teeth at each of .its

l ends corresponding to teeth on the inner ends of the hubs of gears Q and Q', as seen in Figs. 9 and et of the drawings, the teeth on the ends of the clutch working alternately into the teeth on the hubs of said gears Q and Q', and giving rotary motion to said shaft H whenever so engaging` in the teeth of either of said gears Q, and Q', and reversingthe rotary motion of said shaft, as it changes from the teeth of one to the teeth ofthe other, (said spline fw on shaft H is more plainly represented in Fig. 10 of the drawings.) Thereis also cut around said clutch a groove, (as seen in Figs. 4c, 9, and 19,) in which lever o (as seen in Fig. 17 in side view and in Fig. 1S, an edge view) bears and engages for the purpose of changing said clutch from the teeth of one of said gears to the teeth of the other. The manner of moving said clutch by said lever will be explained hereinafter.

The rotary motion given to shaftH produces a rotary motion of shaft H2 by means of said connecting bevel-gears and of horizontal shaft H'. Upon shafts H and H2 are fixed worms L and L', as seen in Figs. 2, 3, 6, 7, 9, and 10, which worms engage with and communicate rotary motion to worm-gears Y and Y', which worm-gears Y and Y' turn freely on studs or axles on arms a and a', as seen in the drawings, and are most distinctly seen in Figs. 6 to ll. ln the outer side of gear Y is cut a camgroove, the form of which is shown in Fig. 12.

Bent lever z, formed as shown in Fig. 2U, vibrates freely on a stud or axle, M, placed on the cleanser-frame arm a., as seen in the draw ings. `From the short arm of the lever z pro- ]ecs a round pin, I), as shown in Fig. 21. This pin b enters and traverses in the cam-groovein gear Y. On the long arm of said lever is a series of teeth arranged in the arc of a circle whose center is m, and which engage with pinion s on shaftD, producing a reciprocating rotary motion of said shaft while the said pin b, projecting from the short arm of lever z, is traveling in the straight parts of said groove, which straight parts (a-s seen in the drawings, marked z' Ic) are arranged at an acute angle with regard to each other, and are connected by a semicircular portion of said camgroove, no motion of said lever being produced while the said pin is traveling in said semi-circular part.

Rotary shaft D is supported in suitable bearings in arms a and a', the said pinion s being placed on the end of said shaft outside of arm a. Said shaft D carries two grooved lifter'cams, T T, which'rare formed as seen in Figs. 13 and 14, which exhibit inner side views of said cams. Besides these cams, the shaft D supports by means of two bent arms, U U, a` bar, V, arranged as seen in the drawings, this bar Y, when in use, having a strip of card illetin g affixed along its under surface, and it may be termed the cleansing or brush bar.

Each top card B B issupported in the usual way on two pins, W, extending from the frame of the card or arch and through the top card near its end. There is also projecting from each end of the top card a small stud, .'v. When the shaft D is turned in one direction it carries the lifter-cams T T toward the Vstuds in the end of the top card for the purpose ot' raising it. The said studs will be received into the grooves of the cams T T, and owing to the eccentricity of the grooves and their peculiar action on the studs the top'card will be raised upward from off its seat, and the brush or card bar V will be carried by the rotary movement of shaft D underneath and in contact with the filleting of said top card. The grooves of the liftercams T T are so formed as to cause the entire under surface of the card of lleting to be brought thoroughly into contact with the cleansing-bar V, the act of cleansing being effected in this wise, viz: The first or forward movement of the brush-bar carries said brushbar under the top cord; then the shaft D being rotated in the opposite direction, the said cleansing-bar is again brought into thorough Contact with the filleting ofthe top card, and in its backward movement cleanses said top card. As soon as the act of cleansing the top card is effected, the lifter cams T T depress the top card back to its seat.

The cross connection-bar d supports by means of two hangers,ff, the pan or trough F, and a narrow bar, g, ofthe salnelength of the pan, iixed on the edge of the pan nearest the card stripper, when at rest. 0n the upper surface of said bar is affixed a narrow strip of card-Iilleting. The brushbar V, in its return movement, after cleansing a top card, passes over said narrow` bar, face to face, and there rests until another movement of the rotary shaft D. At the next movement of the shaft D the lletin g on the brush-barengages with the lleting on the narrow bar, and is thorough] y cleansed, producing a clean brush-bar every time a top card is cleansed, and when the bar yV passes over the narrow bar, face to face, as aforesaid, forces and deposits the waste from said narrow bar into said pan.-

There is attached to and projecting from the circular frame-work or arch, which supports the top cards, the iianges R and B', containing a series of teeth having between them slots or openings G and G' corresponding to the position ofthe series of top cards, excepting that at the end ot the anges, on the doffer side of the card, there are two slots beyond the range of tops, and at the other end are two slots connected by a curved groove, extending beyond the range of top cards. There are also connected by a curved groove two other slots, being the third and fourth from the doffer side, the purpose of which slots and grooves will be more fully explained hereinafter. I will observe that in the manufacture of new cards, the said anges may be cast as part of the new card-frame, and on old cards may be attached to the arch by screws; thickness ofthe flanges about half an inch.

The detent-levers I I are shown detached time that therevolution of gearsYandY iscomin Fig. 15 of the drawings, which is a side view. The space n on this figure represents a large slot in said lever. The small oblong space at the other end of this figure represents a small slot. 'Ihe round space between the two slots is a hole in the lever. Fig. 16 represents an edge view of the same lever, I. Thef'orm of standsh and h is shown in Fig.`22 in side View and in Fig; 23 in edge view. Stands It and h are attached to arms a and a by bolts or rivets, as shown on Figs. 8 and 11 of' the drawings. Said stands support levers I and 1 by means of'studs or screws passing through the round holes in said levers referred to in Fig. 15, as seen between the two slots, and into the round holes in the top of stands It and h', as shown in Fig. 22, and said levers vibrate freely on said studs or screws.

The detents K and K sl-ide in bearings in arms a and a, formed by means of tap p and rivets, and by a lip of studs h and h', as seen in Figs. 7, S, 10, and 1l, and are connected near their upper ends with levers I and I by means of' pins or studs projectingfrom their upper ends through holes in the ends of' said levers, which holes are the small slotsin said levers referred to in description of Fig. 15, which pins or studs work freely in said small slots. There is projecting from the inner sides of worm-gears Y and Y round pinsJ 'and J. These round pins pass through slots n in 1evers I and I ,and project far enough to operate also in the slots or openings G G in anges It and 1t. By the rotary motion of gears Y and Y the round pins J and J describe a circle, the diameter of' which is the space of two slots G G, and the center of which and the inner points of the flanges or openings ofthe slots are equidistant from the center ofthe card-cylinder, so that when the pins J J shall each have entered, traversed, and passed out of a slot the said pins shall have performed l1 alf a revolution. The slots being' fixed and stationary, and the frame being movable on its axis, the said pins J and J by their aetion in said slots will have moved the cleansing-frame the space t f' two slots or top cards. During the remainder or other halfl ofl the revolution of gears Y and Y the pins J and J being removed from contact with the,

slots of' the flanges R and R', no motion ofl the cleansing-frame is produced; but by the continued rotary motion of gears Y and Y' during the other half' of' its revolution the same pins, J and J, acting in slots n of levers I and I, produce an action of said levers by which'the detents K and K are held longitudinally in slots in flanges R and It', thereby holding the cleansing-frame in a state of rest, while simultaneously therewith the pin b traverses the angularA or straight parts i k ot' vthe groove in gear Y, operating through bent lever z, the rotary shaft l), andthe stripping operation is performed. The top card is restored to its seat and the detentive bars K and K are withdrawn from the iianges at the saine pleted. Ihus during one complete revolution ot' gearsY and Y the cleansin gframe is moved the space of two top cards, and is there held firmly at rest while the lifting, stripping, and depressing machinery does its office, the movement of the cleansing-frame occupying onehalf of said revolution of said gears, and the holding of the frame, and process of stripping a top card occupying the other half of said revolution, t'h action on pin b of' the groove on the outside of gear Y, moving the said liftingl and stripping mechanism, the action of pins J and J upon the backside of' gears Y and Y operating in slots n of' levers 1 and I, moving the holding and steadying mechanism and the same pins, J and J, operating in slots G and G of' flanges R and R, effecting the movements ofthe cleanser-frame from card to card, all as hereinbet'ore particularly set forth and specified. The said cleanser-frame having traversed the series ofl top cards, cleansing every other card in succession, and having arrived at. and cleansed card 2 of the series, (marked 2 in the drawings,) the pins J and J enter the slots marked 2 on the drawings in iianges It and It and move therein until they arrive at the points D2, (or at the top slots 2,) at which point the frame will have been moved during the en gagementof' the pins in the slots the space of' one top card. At this time the end of' lever o is brought in contact with the shipping-dog M'. (l will here observe that shipping-rod q, with shippingdogs M and M are shown in the drawings in connection with stand e in Fig. 24 in top view and in Fig. 25 in side or end view. I will also observe thatlever o vibrates on astud aiiixed to arm a, said stud being shown in Fig. 9 on the right limb of' said lever, also that there is aspring (iiiarltetlf)shown inFig. 9,attached to arm @which is to assist lever o in .holding clutch N into engagement with gears Q and Q.) Lever o heilig brought in contact with shipping-dog M, clutch N is thrown out of engagement with the teeth on the hubs of gear Q, and into engagement with the teeth on the hubs of' gear Q', thereby causing the shafts H li and H2 to rotate in the reverse direction and the pins J and J to move off through the curved grooves into slots 1, and out ofslots 1, no motion of' the cleansing-frame being produced while the pins are moving through the curved grooves and through slots l, and while top card, 1, is being raised, cleansed, and restored to its place. Thereupon the cleansing-frame, owin gto the reverse motion given to shafts H, H, and H2, moves back over the series of top cards oprrating upon and cleansing those cards which were not cleansed in the first or opposite circuit of' the frame until it arrives at slots 19, when the same process of' reversing the movements or circuit ofthe cleansing-frame is performed, and when the pinsA J and J arrive at the point D at the top or roof of slots 19, the frame during this engagement of' the pins in the slots having moved the space of one top card, the opposite ends of lever 0 is brought in contact with shipping-dog M, clutch N is thrown up and out of engagement with the teeth in the hub of gear Q into engagement with the teeth in the hub ot' gear Q, the motion of the shafts H, H, and H2 is again reversed, (no motion being given to the frame while the pins are traveling in the curved grooves and out of slots 20,) card 18 is cleansed, and another retrograde or reverse .movement is given to the cleansing frame, as before described, which reverse movements recur by the same process as often as the said cleansingframe shall arrive at the end of its circuit in either direction. The two slots beyond 19 and 20, as seen in the drawings, being the two slots beyond the range of the top cards 011 the dofter side ot' the card, lare to accommodate the action of the detents K and K.

The arrangements hereinbefore particularly set forth are with a view to stripping` every other card 5 but should it be desirable to employ this machinery to strip every card, or to strip anynumber in each circuit of the cleansing-frame, omitting any stated proportion greater than every other card, that object may be accomplished by simply moving pins J and J nearer to or farther from the center of gears Y and Y, so that during the revolution of said gears the said studs shall describe a lesser `or greater circle corresponding to the space occupied by any given number of tops or slots. The diameter of said circle being narrowed to the space of one slot, it will acton every card, or widened to the space of several it will leave an interval proportioned thereto upon they principle apparent y in the foregoing specilcation. It being understood that when every card is not stripped in each circuit of the frame, but stated cards are alternately stripped and omitted, arrangements corresponding to and on the principles of the curved grooves between the slots at the ends of the circuits, hereinbefore described, must be made to ett'ect the reverse movements of the cleansing frame, with reference to the alternate omissions or intervals.

If desired to strip every top card in addition to the removal of the pins as aforesaid, it will be necessary to fill up the curved grooves, so as to have none but simple slots. Also, should it be desired to dispense with any number of top cards at either end of the series, the range or circuit ofthe cleansing-trame may be limited accordingly by simply moving the dogs M or M or both on the shipping-rod q, bywhich `lever o may be brought in contact therewith at any point ot' the circuit of the cleansingframe, and the circuit or movement of said frame be thereby reversed at such point, in manner hereinbefore particularly set forth. It being understood here, also, that where every card is not to be stripped during each circuit, but alternate omissions are to occur,

it will be necessary to have at the termini of the circuit arrangements corresponding to and on the principle of the curved grooves before described, in order so to reverse the movements of the cleansing-frame that the stripping apparatus shall perform at the desired intervals alternately, as Well as within its limited circuit. Y

I will here insert a more particular description ofthe curved grooves referred to. They are shown in Figs. 2 and 3 of the drawings, and are the spaces defined by lines drawn between slots 1 and 2 and between slots 19 and 20, and are of sufficient depth to admit the pins J and J', while engaged iu the slots, to pass through them from from one slot to the other.

rlhe above-described improved mechanism may be divided or separated into three principal divisions or classifications, to wit: First, a cleansing mechanism proper, consisting of the waste-pan F; brush bar V, and card-filleting g, arranged to clean the brush-bar, in combination with the parts operating more immediately in connection therewith to raise, cleansefand depress or restore the top cards; and, second, a traversing mechanism proper, consisting of the cross connecting-shaft Il', rotating shafts H H2, and racks or arches G G, in combina-tion with the parts operating more immediately in connection therewith to produce traversing movements of the cleansingfra-me; and, third, a detent or lockingmeehanisim7 consisting ot' parts which operate to lock or securely fasten and rmly hold .the cleansing-frame while a top card is being cleansed or stripped In a self stripping cardin g-en gine these mechanisms in combination form what may be termed the stripping mechanism. It will be seen that these several mechanisms, as arranged in my improved selfstripping earding engine herein described, bear a peculiar relation to each other and to the arms et a', being all intimately connected or combined with the said arms and with each other, and located mostly above the shaft of the main cardiug-cylinder, in such a manner as to tra-verse or be carried by the said arms, which may be in one sense considered a part ot either of said mechanisms. This arrangement affords a compactness, simplicity, and eifectiveness in card-stripping mechanism not previously attained.

Itis of the utmost importance in all card cleansing or stripping mechanisms of the nature herein described that uniform movements of the two sides ofthe cleansing-frame should be maintained, for reasons which will be readily seen and understood by all conversant with such matters. Prior to my invention the two sides of the cleansing-frame have usually been constructed in an indirect manner by means of a train of mechanism located at the end of or under the card-frame, through which movements have been communicated to the said frame, or from the mechanism at one side of it to that at the opposite side; but such an arrangement is, in my opinion, objectionable for various reasons, which, I

think, will be apparent to all practical carders acquainted with the nature and operation of self-stripping carding-engines. Vhat I consider as the principal objections being the increased cost of acarding-en gine so constructed, the greater amount of power required to run it, the increased quantity of oil required to lubricate it, and unreliability of action as well as liability to get out of order, necessarily arising from the large number of parts used and the nature of their arrangement. For the purpose of obviatin g these objections I make use of a cross connecting-shaft, H', Which directly connects the mechanism at the opposite ends of the carding-engine, and which is so disposed as to traverse with the cleans in gframe arms; and by mechanism operating through said shaft, also traversing with said arms, I cause both sides ofthe cleansing-frame to move in unison, as described, thereby producin g results which cannot be so readily and perfectly attained by any other method.

The importance of locating and combining the cleansing and traversing mechanism, as I do in my improved self-stripping carding-engine, by which great simplicity, compactness, and etticiency are attained, will be readily ap preciated by the practical carder, and is, in my judgment, a great improvement overalily arrangement of those parts existing in selfstripping carding devices prior to my invention. 1t is also of great importance that the cleansing-frame should be tlrml y an d positively locked, or kept at rest, while the operation of raising, cleaning, and depressing or restoring each top-card is effected. rIhis is accom plish ed more effectively where all or nearly all of the principal parts of the locking mechanism are disposed in the vicinity of the upper ends of the cleansing-frame arms, as in my improved stripping mechanism, than it is where any considerable part of them are ata distance from that locality.

My improvement also consists in the combination of a pulley, P', with the traversing, locking, andgcleansing mechanisms, when all of said mechanisms are arranged to traverse with the cleansing-frame, as described, said pulley being located in such a manner that all parts of the stripping mechanism ofthe carding-engine are actuated or driven by a single belt acting on or through said pulley. 'lo accomplish this I locate the pulley on a line with the axis of the shaft ofthe main cylinder of the carding-engine, as shown, as by that arrangement the whole mechanism is greatly simplified, and from that point the most efficient and perfect movements can be communicated to all parts of the stripping apparatus in all of the varying positions of the cleansingframe.

Prior to my invention the cleansing mechanism of all self-stripping carding-engines, as far as I am aware, was very imperfect, fromthe fact that no efficient means was provided in such engines for the perfect cleansing of the brush-bar prior or preparatory to the cleansing of each top card.

My improvement in this relation consists principally in providing a card clothed surface, against or in contact with which the card on the brush-bar is brought and cleansed prior to the cleansing of each top card.

By my invention or improvements, as herein set fort-h, I consider that the following, among other results, have been attained, to wit: First, dispensing with a -large part of the costly, complicated, and unreliable machinery used in self-stripping carding-engines to produce the necessary movements of the cleansingframe; second, producing accurate and reliable movements ot' said frame by means of a simple and direct acting mechanism traversing with thel frameitself, third, so combining and arranging the traversing, cleansing, and locking mechanisms with each other and with a pulley as that all parts of the stripping mechanism may be actuated or driven by a single belt acting on or through said pulley.

I have termed the shaft H a cross connecting-shaft,77 in contradistinction to a shaft, which simply fastens the frame together like d, orto a rotary or rocking shaft used in immediate connecticn with the brush-bar like D, because said sha-ft II' directly connects the traversin g mechanism of the opposite sides ofthe cleansing-frame across or over the top `of the carding-engine, in the manner and for the purposes specified. v

I am aware that there is found di scribed in George VVellmans patent of December U, 18525, a shaft carried by the arms ofthe cleanserframe but said shaft is simply a rotary camshaft forming a part of the cleansing mechanism, and performs no office whatsoever analogous to shaft H' in producing the traversing movements of the cleansing-frame, as, by reference to said patent, it will be seen that it merely carries the cams for raising the top cards, and cleaning and depressing the same, the traversing mechanism in said eardingengine consisting in segments on the lower ends of the cleansing-frame arms, in connection with a complicated arrangement of shafts, wheels, bevel-gears, spur-wheels, mangle-wheels, and escapements, located and arranged at the sides and end of the card. I therefore lay no claim to said cam-shaft in itself considered, or when used simply as described in said patent.

I am also aware that in the English patent granted to W. H. Richie, September 27, 1844, and numbered 10,334, there is found a shaft similar in its arrangement and uses to the cam-shaft shown in the Wellman patent but the sh aft H is different from and used in addition to the shafts (shown in either of said patents) which operate the brush-bar in the machine of the said Richie, motion being communicated between the two sides of the cleansing-frame through a train of mechanism located under or at the end of the main frame of the carding-engine. There is also found in said English patent a toothed rack or arch, the same being a part of or used in combination with the card-frame; also, a cam and gear located on the arm of the cleansing-frame, and operating the cleansing or brush bar. I therefore do not claim the said rack or toothed arch in itself considered, neither do I claim a cam and gear mounted on the arm of the cleansing-frame, in themselves considered neither do I claim the said arch, cam, or gear located, as described, without reference to what I combine with them, (not, however, by this disclaiming in any degree the arrangement and use of the grooved cam and sliding bar, or cam and lifter-bar secured to me by Letters Patent of the United States, dated August l, 1854, said arrangement of a cam and lifter-bar being essentially different from anything shown in said English patent.) Neither do I claim the combining of liftercams T T with brush-bar V and rotary shaft D, nor any device, combination, or improve-- ment described and specified in my said Letters Patent of August 1854, the said devices, combinations, and improvements being already secured to me thereby but I claim as oi'l my invention in self-stripping carding-engines, or iu the mechanism for stripping or cleansing the top cards of carding-engines, the following, to wit:

l. A cross connecting-shaft, H', so disposed y in relation to the cleansing-frame arms a a' as to be carried by or to traverse with them when said shaft is used in combination with mechanism operating in connection with said arms, which produces by means of or through the said shaft, so disposed, conjoint or uniform intermittent reciprocating traversing movements ofthe two sides of the cleansingframe, substantially in the manner and for the purposes set forth and specified.

2. A traversing mechanism proper, substantially such as described, and a cleansing mechanism proper, substantially such as described, combined in the manner and for the purposes set forth and described.

3. A traversing mechanism proper, substantially such as described, a cleansing mechanism proper, substantially such as described, and a locking mechanism proper, substantiallysuch as described, combined in the manner and for the purposes specied.

4. A detent or locking mechanism, constructed substantially in the manner and for the purposes shown.

5. The combination of a traversing mechanism, cleansing mechanism, and detent or locking mechanism with a pulley, P', located on a line with the axis of the main cylinderof the carding-engine, so that the whole stripping mechanism may be actuated or driven by a single belt acting on the said pulley, substantially as and for the purposes set forth and specied.

6. A brush-bar, V, and waste-pan F, disposed in the upper part of the cleansing-frame and carried thereby, in combination with a card-clothed surface or strip of card-flletin g, so disposed or arranged in reference to the said brush-bar as to remove the waste from the same, or to cleanse the card of said bar, prior or preparatory to the cleansing of each top card, substantially in the manner and for the purposes specified.

7. In combination, the lever o, dogs M M', rod y, and sliding clutch N, arranged and operating to reverse the motion of the cleansing'- frame, substantially as and for the purposes specified.

S. The grooves across the teeth connecting the space or slots between the teeth of the toothed rack, in combination Wi th such teeth, whereby the series of top cards,bein g cleansed, is changed, substantially as and for the purposes set forth and described.
