Be it known that I, JAMES JOLLY, a sub- ]ect of the Kingof Great Britain, residing in Bolton, England7 have invented the fol-V easy'removability,.as a unit7 fronrthe comb ing head,.of the sliver-feed means, the. nipper means and the top-comb together :with their several adjustable Amounting's,` all of which are so assembled and relatedf that they can be quickly and bodily. removed for repair', or for Substitution by another similariassembly, or merely: to expose the parts beneath. The separate organization of these parts affords the further advantage that the mechanism of the con'ibing' head .units can be assembled and fitted together 'apart from the rest of the machine with .rt-corresponding saving of labor, and the manner of the' assembly is such as to accommodatea wide lap and. at the .same time` provide ample space for brush-cleaning the head. IVz'trioiis otherl advantages are lalso attained .by the principles herein disclosed and if not .here-v m'pointed out willebe quickly perceived by those skilled in this art.

In the accompanying draw1ngs:-

These'v drawings show only one ofthe heads/of thema'chine which will be understood to comprise six or'more similar heads as customary in multiple-head machines. It will be understood also ,that all'fthe heads are'mounted'on a common base and separated by the frame uprights 1-which carry the operating parts and that they are driven from a suitable drive-.head atone end of the machine. vThe drive-head may be -vari.

ously constructed for this purpose, as 4well known tothe art, and is therefore not herein described. yIt drives the combing. heads,4 in part through the comb cylinder sha-ft2, which shaft extends through all the headsVV carryinga comb cylinder 3 in each head, located .therein directly in rear of the de-y ta'ching and piecing rolls ,4. yThe latter are diagrammatically indicated `because the detail? of vthe mounting vand the specificr means of imparting to them the usual,;intermittent or forward andbackward piecing' motion,.are notimportant to this invention, and can be Supplied by any-.person skilled in this art. It will be understood that their l particularv function is to receive and `detach the combed tuftl and overlap it on. the Apreceding'tuft soas'to produce a continuous` fleece.V

"Each of; thefr-ame uprights l carries on its: .upper surface, and ,horizontally adjustablethereon,.astandard 5. The rear parts of these standards form the journal seats ffory a rock. shaftc also commento all of: the lie-ads'and operated-ffromthe comb; shaft-2 by itsarm .engaging ,a cam, 1er-,cam`` ygroove 8 on that shaft. :The rock shaft is thel .mainioperating 'means for the nipper mechanism and .its associated parts yineach combing head, and while itfis preferably constituted of a single shaft runningA the length fof the machine and-Ldrivenfromf the drive-head, it 'can also'befotherwiseorgan# ized without essentially efecting Ithe operations it performs. .The upper ends of L:the standards 5v carry. the ymeans of'support ofh the removable Vunitaryy assembly above vreferred to, that is to say of the lap plate, and the lapfeed mechanism, thel nipper mechanism and thetop-comb. vAccordingtothe particular design,-this supporting means consistsoftwo journal bearings one onl each standard 5 and each comprising.. a pil-low, block 9 clamped to the side face-.of its standard and capableof vertical adjustment thereon by means Vof the adjusting screw 10. As herein shown one such screw, 10a, serves lblocks of adjacent heads, this being a detail andr associated members as above stated and for this principal purpose its detail design' .is obviously subject to great variation. it

' is preferably a two-part bearing, i. e., comprises a base and cap and it is also in the present case a pivotal, or the support for a pivotal, bearing, since the nipper-mechanism supported thereby is arranged tol oscillate in the process of piecing'and detaching. rlhe organization of the nipper and associated members which are supported in or from this pivotal mounting is assembled in a main frame, which may be termed the nipper frame and is shown by itselfv in Fig. 6. llt comprises a shaft or shaft.- like part 14, the ends of which are adapted to rest in the two-part journal bearings above referred to, and a single casting permanently fixed to the shaft part and comprisingV an upright crossV member or lap- ,plate 15 joiningtwo vertical side members in the form of thin plates 16. This frame, when mounted as' described, is VVVadapted to be moved back and forth or oscillated by its yoke connection 17 which is detachably connected to an eye-bolt 18 pinnedV to a short crank arm 19 carried on the rock shaft above referred to. The operating connection is readily detachable from the rock shaft by backing .off one of the nuts on the eye-bolt and allowing the latter to drop out Aof the inverted U-shaped socket (Fig. 6)

in which it isV normally clamped. The cushion plate 20 or lower nipper jaw is adjustably secured to the lower thickened edge of the lap plate 15 and the nipper knife 2l. which co-acts therewith. is carrieiil by a pair of nipper arms 22 each fixed 'to the ends of a rock shaft 23 which is journaled in the side plates 16. The upper arms 22 are located outside of the side plates of the lswinging frame. The rock shaft` 23 carries fixed on it, inV rear of the lap-plate two rearwardly and upwardly extending -arms 24C provided with friction rollers 25 adapted to engage the rear faces of the cam tracks 26 when the rock shaft 6 swings the frame forwardly von its pivotal `axis 14. T his causes the nipper knife to open against the tension of the nipper springs 27 which latter are connected between Vthe ends of the arms 24 and a Vpoint on the upper rear side of the lap-plate, as shown in Fig. 1.

The nipper-closing springs thus move bodily Y with the oscillating frame. The nipper cam tracks 2G are supportedon the frame bar 23 by an adjustable joint 29, the purpose and construction of which will be plain without explanation, and the friction rollers Q5 are also adjustable on their arms 27 so that both ends of the nipper knife may be set for simultaneous andequal engagement with the cushion plate. 1t will be apparent that the rollers and cam tracks constitute an operating connection between the nipper and a fixed frame part whereby the nippers are opened by the effect of, and at a predetermined point in, the forward swing of the frame. This function of said operating Connection can be performed by other means which will likewise be readily separable when the frame assembly is tofbe removed. Y

rlhe lap to be combed is taken from: a lap roll carried on the usual creel rollers 30 being conducted thence over the shaft part 14; of `the nipper frame and thence downwardly over or in front of the lap plate 15, and thence forwardly under the feed roll 31 which is corrugated. rlhis roll is supported by its gudgeons at each end in the open notches .in the ends of the two feed roll levers 32, which levers are fulcrumed on studs 33 projecting outwardly from the sideplates 1G 0f the nipper fra-me and connected at their rear ends with the` feed roll springs 34. rllhe other ends of the feed roll springs are connected tothe rear side of the ilap plate like and adjacent to,` the nipper springs so tha-t'both sets of springs are carriedby the removable unit. The studs 33 are adjustably,secured in slots 34 in the side plates 16, as shown more clearlyV in Fig. V'7, so that the position .0f the feed roll with respect to the bite line of the nippers may be adjusted forward and back as desired. One end ofthe feed roll 31 is projected beyond the journal notch in its holding arm 32 where it carries a vratchet wheel, shown in Fig. 3, the latter being enclosed in a box lever 35 journaled on the feed roll gudgeon and carrying` a pawl by which the .ratchet and feed roll are rotated.v For this ard 5, and when so engaged the oscillation Y Y of the nipper frame on its axis 14, will os-` cillate the boX lever on its aXis and thereby rotate the feed roll and advance the lap acv cordingly. This feed roll hook can be swung out of engagement with its stud 37 whenever desired, and when so disengaged the feed roll can be manually rotated by the thumb wheel at its opposite end.

The top comb 38 isfastened to the usual head piece and is adjustably secured to and unites the two top comb arms 39 which lat-v ter are journaled concentrically to the feed roll arms 32 preferably on the bosses 40 thereof, and around the heads of the studs 33, see Figs. 2 and 7. As shown more clearly in Fig. 1 each top comb arm 39 is provided with a friction'roller 41 projecting laterally Ytherefrom and adapted to Vengage a cam track 42 adjustably fixed to the inside face of the adjacent standard l5. When the nipper frame is oscilla'tedV to its rearward position the top comb rollers roll up the 'cani tracks 42 thereby causing the top comb to be lifted relatively to the nipper frame, or at least to follow a path not likelyl to collide with the comb cylinder. In the forward oscillation the rollers 41 roll off of the cam tracks 42 and in that event the top comb arms are supported by the set screw 43 with which each is equipped, said screws being adapted to seat upon the lugs 44 projecting from the outer faces of the side plate 16 of the nipper frame. The adjustment o-f these screws determines the depth of penetration of the top comb .teeth into the tutt. as willbevapparent.

By the arrangement above described, the feed roll levers, nipper arms and top comb arms occupy substantially theA same plane, all outside of and close tothe adjacent side plate 16 and such disposition permits the width of the combing head to be relatively narrow with respect to the width of the lap while providing ample space between said arms and the adjacent standard to insert the hand or brush for cleaning the parts-a matter of much importance to the quality of the combed product. And in addition to this facility ofaccess, the whole head structure above the comb cylinder can be removed when desired and as above described by simply removing the journal caps 11 and dropping the eye-bolt 13 out ofthe yoke. The removal thus permitted, uncovers the comb cylinder and its doiiing brush or other' scavenging means (not shown) so that they can be closely inspected, or removed, upwardly, if desired, thereby avoiding the need of providing special access to these parts in rear of the machine as well as affording other conveniences. These several considerations adapt the'head structures to be assembled in a single frame, back to back, thereby producing a duplex or double-sided machine as shown diagrammatically in Fig. 8 and whereinv a double- -sided nippervframe 45. is removably hung on an axis 46 being oscillated by a rod from the shaft 6, over two adjacent comb cylinders. This frame carries lap plates'and cushion plates 47, nipper knives 48, feed rolls 49 and top combs 50, all arranged Ain the relation above described, except that the nipper arms are fulcrumed on acommon shaft or axis 51 and their free ends-(52) cross and extend to the opposite sides respectively and are connected by a single spring for closing them against the cushion plates. The nipp'ers are opened by indicated. A single spring 5.4 connects the feed roll levers 56 and provides'the feed roll pressure, such feed rolls being otherwise operated as above described. The' top.

comb arms are similarly mounted on a.v single axis 55, but are otherwise the same as the top comb iirstvdescribed. By disconnectingy the frame 45 and its shaft 46 from its snp,- port (not shown) and from its oscillating means, the entire duplex nipper mechanism' can be removed as will now be apparent..

As shown more clearly in Fig. 6 the' nipner frame is formed with two projecting' flanges 60, constituting guard rails for the selvage of the lap and these rails are obliquely notched atl their lower ends to hold a clearer cover in position on top of the feed roll.
