Speocat'on of Letters Patent. Patented Dec. 29, i910.

Application filed December'f 1908. vSerial No. 466,615. i'

To all whom it may concern:

Be it known that we, ALFRED B. Evans nud FRANK MARCAURELE, citizens of the United States, and residing at New Bedford,

si in the county of Bristol and State' of Massachusetts, and FRANK RfLANcLois, a citizen of the United States7 residing at Vvloonsocket, in the county of Providence and tState of Rhode Island, have invented a new 1'; and useful improvement infCombing-Macliii`ies,'of which the following is aispecification.

This invention has reference to an improvement in combing machines and moreparticularly to an nnprovement in that form of combing machines known as the Heil- 'mann comber for combing cotton and similar fibrous material.

ICoinbing machines as heretofore constructe'd and operated on thcprinciplc of the wellknown/He'ihnann comber usually have the following motions and complicated.mecha- 'nisms which are discarded in our invention:

the upper lap feed roller and its spring ten- Z sion connections, the nipper frame, the nipper knife and its cam operated mechanisim and the intermittent backward rotation of tlie'drawing off or detaching roller and itsl o'erating mechanism, all of which materially limit .the speed and pioduction of the machine. r

The objebt--of our invention is lo improve the construction of a combing' machine, whereby a large number of the parts and .35 their operative mechanisms heretofore used are eliminated thereby inereasin the s )eed and the production of the machine and re# ducing the cost of combing the'matcrial.

A further object of our invention is to sim- 4-0 piify the construction of a Heilmann form of combing machine, thereby reducing the cost of'manufacturing the machine.

Figure l is a vertical transverse sectional View takenrcentrally through one of the combingl heads of a combing machine cmbodying our invention.

p Fig. 2. is an cnlargeddetail sectional view similar to Fig.

, of the rolls, feed plate and top comb, illustrating our improved method of overlapping o'r piecingthe combed staple, which is indicated in dotted lines. Fig. B is an enlarged detail view' of the top portion of ay gearing stand and showing the means for rigidly securing the ends ofthe lap feed plate to the bearings `of the lap feed roller. Fig. 4 is a top plan view of the driving mechanism fo'rthc combing cylinder and detaching rolls' and the intermittent motion mechanisms for the lap feed roll and the intermittent piecing' rolls. Fig. 5 is a vertical sectional view taken on line 5 5 ofFig. 4, showing the intermittentniotion mechanism for the lap feed roller, with the gear stand removed. Fig. (i is a vertical sectional view taken on line 6 G of Fig. 4, showing theintermittentmotion mechanismv for the intermittent piecing roller, and Fig. 7 is a vertical sectional view, showing them'echanism for constantly driving the detaching roller.,`

In the drawings.r a indicates the main horizontal gider forming a part of the frame and extending the length of the machine for the common support of the several combing heads' and gearing stand and supports c mounted on the girder and forming supports for the several operating parts, (Z the driving-shaft having the pulleys e and pinion f meshing with the gear f/ on the shaft zy 'of the combing cylinder t', 7c the cleaning brush,

l the doiling cylinder, m the doifer comb, ln,

the lap rolls, 0 the apron, y? thelap feed roller, r the top,comb, s the detaching roller,

t the sliver can, o the calendering rolls, and w the sliver apron of a combing machine embodying our invention, which consists -of a lap feedl intermittent motion mechanism 8 for the lap feed rolls 7;, a lap feed plate 9, a

tatably supported in thc bearings 14 which are adjustably secured to the topof the supports ff m the usualvway, as shown in Figs. 3 and 'i. The feed roller 7) maybe held so as to revolve in a fixed position relative to the lap feed plaie 9 or held' under Aa yieldingl downward pressure by any well knownmeans. y

The lap feed intermittent motion mechanism S consists of a disk 15 supported con-' centricallyonthe shaft 7L of the combing cylinder e' and preferably adjustably setitl cured to the gear y, au otlcenter .sind itl on the dial; l5. a Star wheel l? on the outer end ot a shaft ltl, supported `1n bearingsl in the l,gear stand in a position for the stud to to end of the .shaft 1B odi. the lap teed roller 7),`

as shown in Fige. land 5. rlhe construction of the disk 15, Itud .ttl and star wheel` 1T is similar to and operates on the principle of the well-known Geneva Stop motion.

The lap feed plate i) extends the length of the combing` head and constructed in the t'orm ot a bar having;` the tlat vertical portion 2l. and the. bach iardly-curved lower lip forming` the segment. of a circler` the center' of which coincides with the center of the lap feed roller y). This plate is rigidly secured. as lhewn `in Fig. 3, at each end to the bearings ll tor the lap feed roller y in a. position tor the curved lip 22 to extend lnieltwardl)v under the lap feed roll j) to approximatel'iv a line drawn rerticall)7 through the center o1' the roll and to torni a thin eoinentrie Space (when the roller p is held in. a lined Iposition relative to the plate 9) between the lap teed roller p and the lap Steed plate tor the lap, which entere the il-Shaped Space between the lap feed roller p and the lap feed plate t), as shown in dot ted'lines in Fig'. 2.

The conelant driving` niotion mecianiem l() tor the detaching roller s consists of a gear 23 `Secured to the Shaft 71. of the combing cylinder apd meshing with a pinion A formed in tegral with a gear 25 which meshes with a pinion 2G on the shaft 2T oi the detaching roller rthe pinion Q-t and gear are rotatablyr supported on a stud 2S secured tothe eupport, c in a position for the pinion 2ito mesh with the gear Q and for the gear 25 to mesh with the pinion 2th aS shown in Fics. #l and T. A roller 2f) .ie .held under pressure in Ytrictional contact with the detachiir;Y roll ,sx aS Shown .in VFig'. l, b r an)Y ot' the well known ineanS.

The intern'iittent pierino4 roller ll has a Shaft SO rotatablir l@upported in `uitable hearings` (not Shown) on the Supporte c in a position to bring thtl roller above and toward the Sliver can f. and a roller 3l is held under pressure in trietional contact with the piecincy roller ll. as Shown in Fie'. l., in

.any suitable manner.

The intermittent piecin;Y motion mecha niam 12 cousins ol. a dial; 32 secured to the Shaft il, ot `the combinev cylinder i, an ott'- center `stud lll on 'the disk 3Q. a atar wheel 34tsecured to one end ot a Shaft, on the opposite end oi which a ,Qjear meshing1 with. a pinion 37 on the end oil the shalt 3Q of the pieclng` roller ll. The shaft is roarance tatahly Supported in a hearing il@ on the upper end of a bracket Si.) secured to the eupport c in a poaition l'or the stud 3? to en gage with the star whee Bt and for the Pejear ISG to mesh with the pinion lil, as shown in Figs. ft and tl. "lhe foristinction and opera tion of the dish 32, letud l-3, and star wheel 3ft are the'eai'ne as that Shown in the lap feed intermittent motion mechanism ln the operation of our improved combingl machine the lap feed roller 7) has an intermittent forward rotation, as indicated by the arrow in Fig. 2, (the duration ot' each .intermittent rotation corresponding;` to the length ot' the Staple) through the .lap feed intermittent motion mechanism 8. The lap feed plate 9 is rigidly secured in its opera tire position. The detachingr roller a re volvere conetantly in 'the direction oit the arrow. as indicated in Figi". i2, through the conrstant drivingA motion mechanism 10 and the intermittent piccino; roller l1 has an intermittent it'orward rotation through the intermittent piccino,` motion mechanism l2, the duration et each intermittent motion corresponding' to the length of the staple. rthe roll ol lap is carried on the rolls n and the layer ot lap unwinding therefrom paeeee down the apron o into the lit-shaped Space or opening' between the .lap feed roller y) and the lap t'eed plate 9. Ifthe lap is now Squeezed between the lap feed roller p and the lap feed plate 9 and forced through between the same by the intermittent rotation oitl the lap feed roller 71 into the path oi rotation ot the combing; cylinder i. The ende ot the staple which project downward 'from the lover edge oit the lap feed plate 9 are eon'ibed oy the teeth or needles on the combm ing,` cylinder 'i' in the usual manner and are ,then engaged by the detaching halt-lap or Segment on the coi'nbinc cylinder which cooperates with the detaehingi' roller s in the usual 'a5'. to separate the staple from the lap which ie now held by the nip or bite of the lap feed roller y) and the lap iieed plate il. at the Same time draepingD tl Ctaple through the teeth ot the et@ iionarjf top romh fr. which adjusted to he just clear of the path of the segment. rlhe staple now passes between the detachinp roller e andthe nipper roller Q9 to the intermittent pieeing roller ll which with the top roller 3l intermittently advances the Staple and then holda the tail ends oi." the Staple until the next advancing' Staple overlaps the same, as indicated in dotted lines in i). The detachinn' roller .v and piecine` roller lil tnen advance both the staples simu taneousljii, thereb)Y pieci'ngf the same. rlille pieeed Staple einert'eS from the rolls in the vtorni or a etnitinuous sheet and4 pas c5 through 'the calenderingr rolls fu onto the` Sliver apron 'ze npon which it ted alone' to the drawhead in the usual manner. The com "inge or inder Z and removed from the latter bytheoscillating'doii'er comb m alloperating in the usual manner.

`n isevident. that the @aus may be placed in anyposition desireda'elative to each other angd that the construction of the mechanisms for operating the rolls may be varied within AWide limits Without materially aecting -the spirit .fof our invention. A

Having thus described our invention, We claim as new and desire to secure by Letters l. Ina combing machine, the combination vWith lap feeding means, and a combing cylpiecing rollers; andumeans for intermittently rotating said piecing rollers, whereby the ends of the lengths of staples fed thereto are overlapped and pieced together and subsequently advanced.
