To (MM whom, it may concern.-

Be it known that I, ISAAC Bns'r, a citizen of the United States of America, and a resident of Lawrence, in the county of Essex and Commonwealth of Massachusetts, have invented certain new and useful Improvements in Machines for Uolnbing Wool, of which the following is a specification.

My invention relates to improvements in wool-combing machines; and the object of my improvement is to provide adequate means to force through an elastic medium the wool into the combs. A brief summary of the present way of securing this result may be appro )riately introduced as follows, assuming his description to refer to the Noble comb: The large and small circles herein illustrated move in tangential paths relative to each other, and they carry concentric rows of vertical pins constituting in their entirety the combs. A complete set comprises one large and two small circles situate within the area of the larger, the small circle of ins almost contactin with the larger at iametrical points, an all revolve in the same horizontal direction and at the same speed. The sliver of wool to be combed is without any twist delivered from the creels (not illus-' trated) through the series of feed-boxes surrounding and a part of the machine-bed, whence they are drawn into the circles for combing at their oints of iuxtaposition. As the revolving circles diverge from each other a portion of the wool adheres to each, afterward drawing the sliver out of each circle throu h the pins and again uniting the wool to ma 'e the combed top. It is at this point-the momentary junction of the re volving pins or combs-thet the wool must be dabbed into them, which is new accomplished by dabbing-brnshes having a. vertical motion. This method has always been diilicult, for the brushes must move with exeeeding rapidity or the sliver is not dabbed down precisely at the junction of the circles and in eonse uence of this very quick motion the brushes do not rise hi h enough, and the wool is milled and rubfied sidewise as it passes under the brushes and is not sufiiciently dabbed down. The bristles com osing said brushes also become wasted an reflexed at their contact ends, and thus draw portions of the fibers out of the combs which will produce noil-knots." These are dragged over the pins, inevitably making bad work and often breaking the combs, thereby disarand one of the small circles of combs.

ranging the dabbing mechanism. The ordinary dubbing-lunches are therefore not always reliable in their eiliciency and always a source of great expense and much nnnoy once.

To obviate such disadvantages is the purpose of my invention, which I accomplish through the apparatus herewith illustrated, comprising, briefly, a series of vertical tubes ada ted as conduits directing fluid currents in tirect and divergent streams upon the wool sliver, acting in conjunction with horizontal rotating drums provided with surface material to )IQSS the wool farther into the combs, teget or with vertical and lateral adjusted presser-feet confining the wool below the points of the combs.

Referring to the drawings, Figure l is a perspective view of a suliicient portion of a wool-combing machine to exhibit my improvement thereto attached. Fig. 2 indicates an elevation of the front in connection with a portion of the comb. Fig. 3 designates a plan, in art section, of the same lpositioned above a ragmentary part of theFarge 1 4 is a. front elevation of the principal mom or of the tube group with its feet in section. Fig. 5 re resents a side elevation of the same on line 0 section 5 5 of Fig. 4, sufliciently sectioned to disclose its construction. Fig. 6 illustrates in perspective the secondary memher with its orifice in section displaying its internal arrangement. Fig. 7 is a longitudinal central section of the intermediate members, the several members being detached views. Fig.8 indicates the devices employed to vertically adjust the brushes in their reletion to the combs detached from their supporting-pillars. Fig. 9 denotes a transverse section of the same on line of section 9 9 of Fig. 8. Fig. 10 represents the endless belts which may be adapted in lieu of the rotative brushes. 7

Corresponding numerals designate similar features throu 'hout the several drawings, re ferring to whic 1 1 indicates the bed of the machine, and 2 the pillars arisin therefrom. The appara tus as a whole is esignated 3 each bem secured to said pillars firmly by brackets 4, 1g, 2, or in other suitable ways. 5 represents threaded sus ension-bolts (passing vertically through sai brackets an held in ad ustment therein by the nuts 6. Said bolts are each secured to the brackets 7, movably attached to said pillars 2 by bolts 8 or in such other manner as to permit, through the agency of the bracket slots 9, the vertical adjustment to or from the combs of said bracket with its accompanying accessories. The brackets 10 are each attached to the brackets 7 in a like manner, so that they have a horizontal adjustment in. relation to the combs additional to their vertical adjustment by the brackets 7, previously described. The brackets 10 support the main conduits and their coacting members, hereinafter described. 11, Fig. 3, represents rightangle slide-plates capable of vertical adjustment in relation to the combs, being attached to said brackets 10 and adjusted vertically by nuts and bolts through slots in the manner already described. The lower or horizontal portion of said plates 11 are furnished with slots 12, which receive the screw-threaded stems 13, suspending the presser-feet 14, and adjusted vertically therein b the checknuts 15. Said resser-feet are 'ormed substantially as illustrated and rovided with sockets 16 on their upper sur ace, which receive the stems 13 and are therein secured by the locking-nuts 17. Through these means an axial adjustment of said presser-feet in addition to their vertical movement is obtained. These retaining presser-feet are located between the circles at their tangential junction, (shown in Fig. 3,) and their pur pose is to revcnt the sliver from rising abovethe pins a 'ter the wool has passed beyond said junction of the combs into which it has been pressed as it comes from the feedboxes.

The horizontally-rotating brushes 18 are peripherally provided with oints for stroking transversely the fibers o the wool as the sliver passes to the combs. For this pur pose bristles or preferably wires as exemplied in card-cloth are employed. The arbors 19, on which said brushes 18 revolve, are secured to movable plates 20, Fig. 8, having racks 21, enga ing with the segment-gears 22, secured to t e plates 23, attached to the pillars 2, and provided with guideways 24, the latter plates ernbracin the edges of plates 20 in a manner that their vertical adjustment, together with their brushes, toward or away from the combs is accomplished by the coaction of said segment-gears and racks through the manual] '-aetuated gear-handles 25. The rotation o the brushes is accomplished by contact of their points with the combs aided by the interposed wool sliver, and their speed obviously is that of the circles, their adjustment bringing the points of the brushes at a predetermined distance below the combs to secure the results desired. An alternate method of obtaining like results is secured by endless short belts or aprons of card-cloth carried over antifriction-rolls supported on arbors in the position shown in Fig. 10 at 26. Said aprons and rolls are retated by their points through the lattcrs con tact with the combs, previously explained.

The main conduits important factors in carrying my invention into eli'cct-are shown at 27, horizontally, vertically, and radially adjusted in the brackets 10 and which receive an elastic medium in the present instance air-through the bifurcated tube 28 or in any other preferable mannerfrom a blower, reservoir, or other source of supply unnecessary to illustrate. The lower ends or tenninals of these conduits 29 are flattened somewhat transversely in their relation to the combs, as in Fig. .5, and have their orifices flaring in the same direction as shown in Fig. 4. Said orifices have foraminous barriers or floors 30, with additional semicircular openings 31 of increased size over their associated perforations and located in position above the combs, so that a slightly-increased volume of air impinges on the sliver directly at the point of meeting 32 of the combs, Fig. 3, over that passing through said perforations. This is facilitated by the inclination of the floors, as illustrated in Figs. 2 and 5.

The secondary conduits are constructed substantially as exhibited in Fig. 6, having fan-shaped terminals 33, deep at their rear and terminating witdhwise in narrow orifices 34. Sinuous vertical partitions 35 he just back of these orifices and are perforated for the egress of fluid currents, as at 36, which flow in conver ent and divergent streams, as indicated by t e arrows, and which restores the stray fibers of wool to the points as the slivers traverse the combs and just previous to their coming under the main pressure.

The intermediate conduits 37 are illustrated in Fig. 7, their orifices 38 being slightly less in depth and without partitions, their conformation otherwise corresponding with the terminals 33, their purpose being to restore the fibrillous wool (if any) which may elude the action of the terminals 29 33 within the air-zone of the main conduits, whence it is driven back and returned to the combs.

Transmission of air from the main conduits 27 is downward through the by-passages 39, which suspend the group of terminals 29 33 by their telescopic construction, the deflection of a part of the main column of air being materially assisted by the reentering ends 40, as in Fig. 5. Both the main conduits being thus equipped, the vertical and axial adjustment of said members in their relation to each and to the combs is secured and the permanency of all conduit adjustment maintained by set-screws 41 and thumb screws 42 or in any other well-known manner.

It will be observed from the foregoing that a horizontal adjustment of the main conduits toward or away from the tangential -junction 32 of the circles, as well as the vertical adjustment to or from the combs, together with their axial movement for the IIO slight radial adjustment of the terminals over the combs or the individual independent movement of said terminals in their relation to the eircles, is attained through this multiple adjustment of the several memberswhilc the alinemcnl and rigidity of all the parts comprising my improvement is assured.

Having thus ascertained the operation and construction of my in'iproved invention, I do not confine myself to the exact details herein illustrated, as the same may he variously modified without departing l'roin the spirit thereof.
