Divided and this application August 13, 1942, Serial No. 454,749 11 Claims. 1 (Cl. 19--116) The invention relates to Heilmann type comb ers, being- a division of my application, Serial No. 359,385, filed October 2, 1940, Patent No. 2,353,812 to which reference may be had for any matter herein shown but not described. The object of the present invention is to irn prove the supporting and control means, the op eration and the convenience of use of the top combs in combers of the kind referred to. In the accompanying drawings Fig. l is a, gen eral cross-section through a comber to which the invention is applied; Fig. 2 a front elevation of one of the combing heads thereof; Fig. 3 a cross section of Fig. 2 in a plane adjacent to one of the top comb arms, showing the top comb in sec tion; and Fig. 4 is a top plan of Fig. 2 showing also parts of the drive head. It will be understood that in such a comber there are ordinarily several combing heads of which the operating parts are driven from the 20 2 the tuft from the lap still held by the feed roller 5 and pull it through the teeth of the top comb I3 which has been lowered for that purpose. The top-comb combs the tail ends of the fibers con stituting the tuft as they are drawn forward by the detaching rollers. The detaching rollers receive the front end of the tuft on top of the tail end of the preceding tuft, with an appropriate overlap, thus píecing the tufts together to form a continuous fleece composed of a succession of imbricated tufts. For this purpose the rollers are given an alter nate forward and backward rotation, referred to as the píecing motion. In their forward motion they detach the tuft, as just stated and in their backward motion they return and expose a con siderable length of the rear ends of the fibers in position to be overlapped by the next-arriving tuft. Ordinarily, also the axis of the top roll Il is traversed forwardly and backwardly over the top of the bottom roll l2, in synchronism with drive-head, at the end of the machine, by means of longitudinal shafts extending through al1 of the intermittent rotation, so as to facilitate the the combing heads, and journalled on vertical overlapping process. Its two extreme positions frame uprights l located between the heads. One are indicated in the drawings. of these shafts operates the top comb system of 25 The top comb system, shown best in Fig. 3, is this invention. automatically advanced and retracted with the The dotted circle at the top of Fig. 1 repre nipper mechanism but with a different motion sents a roll of cotton lap to be combed although and through a different path.

By the feed roller 5 the lap is de the arrangement being such that the subframe livered to the nipper jaws v8 and 9 of which the and its top comb can be lifted and turned with lower jaw, or cushion plate, is fixed on the nipper respect to the arms and without lifting the lat frame which is mounted or hung so as to be mov ter, to the position indicated in‘dotted lines in able toward and from the detaching mechanism. 40 which the comb points forwardly and rests in a The other jaw, or nipper knife 9, opens to receive position where it can be easily inspected and the lap fed by roller 5 and then closes upon it cleaned. In this position the studs 62 rest in and nips it, holding the projecting end thereof notches 63a at the tops of slots B3. The comb in the path of the -comb teeth on the comb cyl is quickly replaceable to its working position in inder I0 whereby the forward ends of the lap 45 which the subframe rests by its studs 62 in the fibers are combed. After such forward ends have bottoms of the slots 63. been thus cylinder-combed, the nipper jaws 8 and Each top comb arm is pivotally supported at 9 moving forwardly, deliver the terminal tuft of the rear of the comber in the end of an upstand combed fibers to the detaching mechanism, open ing crank arm 66a of the longitudinal top comb ing at the same time, so that the tuft may be 50 wag shaft 61, and each top comb arm has a track drawn away from the body of the lap. 68 by which it rests on a top comb roller 69, the The detaching mechanism includes a pair of latter being mounted in a fixed position on an back rollers Il and I2 which seize the front ends appropriate adjustable bracket ’l0 on the part 4| of the comber fibers presented to them by the carried on the adjacent frame work. The rollers nippers, and by their forward rotation separate 55 69 determine the position of the top comb arms 2,410,150 3 and top comb. As the top comb wag shaft 61 oscillates, the top comb receives a correspond ing to and fro motion in the direction prescribed 4 |59, H0, |20, |2I, |22, |25, |26, |21 and |28; the creel system comprising the parts 33, 34, 44, 45, 45 and 49 ; the nipper system comprising the parts 25, 2s, 21, 2s, 29, 3i, 32, 35, 31, 3a, 39, 4o, 41,42, but sufñcient to let the top comb descend, in its Ul 54, 55, 55, 51 and 58; the scavenging system com prising the parts 2|, 22 and 23; the detaching and forward position, well into the tuft being drawn piecing system comprising the parts I4, l5, I6, 15, off by the detaching rolls. The to and fro motion by the slope of the roller track 58, which is slight given to the comb causes it to follow close behind the top detaching roller || as the latter makes its forward traverse (to assume its dotted line position). The top comb is shown in its high, position in Fig. 1, the nipper jaws beingl still closed. This movement of the top comb is cus tomary but is commonly imparted to it, in this type of comber, by the nipper frame itselfv or by connection to the detaching roll, whereas in the present case it is imparted to it by the wag shaft 1B, 11, 18, 19, 82, 83, 84, 85, 81, 81a, 88, 89, 95, 90a, 5|, 92, ||3, H35, H4, ||5 and H9, and the de livery system comprising the parts |1, I8, I9, 20, 93, 94„ 95 and 96. I claim: 1. In a comber, a pair of top comb arms, a top comb subframe, links connecting it to said arms, stud-and-slot connections between said subframe and arms to guide the link-permitted movement of Said subframe with respect to said arms, a top comb ñxed to said subframe and means for oscil such as 51, at the rear of the comber and driven lating said arms. from the drive end of the comber. 2. A top comb system comprising a top comb It is sometimes desirable to impart a quick 20 supporting arm, an oscillating support therefor, downward movement to the top comb so as to promote a positive penetration of itsv teeth into heavy lap. This quick drop is afforded in the present case by supplementary tracks`A adapted to engage the same rollersßg. Each of these tracks is in the form of a latch member, marked 1|, adjustably pivoted at 10a> to a top comb arm and another support therefor including a fixed top comb supporting stud, a track on thev arm riding on said stud in the rearward stroke and a supple mentary track on the arm riding on said stud in the forward stroke and adapted tol fall off of it at the end of such stroke. 3. In a .comber having a comb cylinder, a rear extended downwardly adjacent to the track 58 to support located behind the cylinder, top comb be engaged by the roller 69. Each latch is held -against swinging on its pivot in the forward stroke 30 arms hinged to said support land extending for wardly therefrom, means intermediate said sup ofthe arm, by> an adjustable stop 12, and the port and the front of said arms for determining several parts are so arranged that on such for the position of the .top comb with relation to the ward- stroke, the latch mounts and rides on .the tuft, a subframe-supported on the front ends of roller 62 until it drops .abruptly off of its front said arms,`links connecting said subframe» to the side, thus giving the quick drop-to the comb i3. arms and stud and slot means between saidY sub Onthe return movement, the latch swings on its frame and arms prescribing the path of move_ pivot dragging over the roller so 'that the top comb rests on tracks 58 and recedes in a path lower than that in which it advanced, combing ment therefor when swinging on said links. 4. In a comber-a pair of top comb-arms, a top the tail of the tuft at the same time, thus re ceiving a two-way motion for effectively combing .the übers.

It provides for adjust ment in all directions as will be apparent. It will be observed also that the whole top comb structure can be swung completely out of the combing head by turning the arms over and back on the pivots of the cranks 55e, this being- a special virtue of the rearwardly located hinge support of -the arms. The drive of the top comb wag' shaft 61 is in dicatedin Fig, e as taken from the nipper wag shaft Silthrough a pair of segmental gears 13 and 14, but so far as this invention isV concerned the means of driving it is of no consequence. The principal parts of the combing machine in which the present invention is illustrated, but which are not directly related thereto, include the following: The drive-head mechanism com prising the gears |23, |522 91, 9S, |05, |05, |08, ported also on ñxed means between their pivotal rear support and said top comb. 6.
