DRAWING-OFF ATTACHMENT FOR COMBING-MACHIN ES.

SPECIFICATION forming part of Letters Patent No. 730,021,'dated June 2, 1903.

Application filed June 18, 1902.

To all whom it may concern:

: Be it known that I, WALTER BRIGHT J EF- FERSON, a citizen of the United States, residing in the city and county of Philadelphia,

5 State of Pennsylvania, have invented a new and useful Improvement in Drawing-Off Attachments for Oombing-Machines for Wool, of which the following is a specification.

My invention relates to improvements in r: drawing-E attachments for combing-machines; and it consists of means whereby the endless aprons between which the long strands or, tops pass are not subjected to the strain to which they are at present sub-' r jected, thereby prolonging the working qualities of said aprons and reducing to a minimum the necessity of replacing broken or worn-out aprons.

It also consists, of novel details of construction, as willbe hereinafter described.

Figure 1 represents a plan view of a portion of a combing-machine 'for wool having my drawing-0E attachment herein described placed in position thereon. Fig. 2 represents 2 5 a side elevation of certain of the parts seen in Fig. 1. Fig. 3 represents a partial-side elevation and partial vertical section of cerwin of the parts seen in Fig. 2, the section being taken on line main said Fig. 2. Fig. 4 represents a horizontal section of a portion of a grooved wheel employed in connection with my invention. Fig. 5 represents a side elevation of a portion of a grooved wheel employed and Wires employed in connection therewith and illustrates the manner in which the tops or long strands of wool are retained on said wheel. Fig. 6 represents, on an enlarged scale, aplan view of certain detached portions, of the device.

Similar letters of reference indicate corresponding parts in the figures.

Referring to the drawings, A designates a portion of a wool-combing machine, and the parts composing thesame, except asherein- 5 after claimed as new, belong to that type of machine known as the Nobles combing-machine and to'which I have applied my improved drawing-off attachment.

B designates a ring which is provided with Serial No. 112,183. (No model.)

the feed-boxes 0, through which the slivers O of wool are passed, said slivers being drawn from a ball or bobbin D, supported on a creel D, it being noted that only one bobbin D is shown in the drawings, although in practice several of these are employed.

E designates a ring suitably supported on the frame of the machine, so as to turn thereon, it being noted that said ring is provided with'pins F, which constitute a comb, audit is to be understood that in practice the pins F exist all the way around the ring E, although in the accompanying drawings these are shown only partly around said ring.

Located within the ring .E are rings G, which are supported on steamchests'G and adapted to turn thereon, it being noted that said rings. G are provided with pins H and that the rings, G and pins H constitute combs which operate in'conjunction with the comb formed by the ring E and pins F, the object of all of which will be hereinafter described.

H designates a wheel Whose periphery'is' provided with serrations J and grooves J, (similar to the grooves U, seen in Fig. 5,) it beingnoted that the wheel H has, upon its upper face ratchet-teeth K, with which engages the inner end of a lever or breaker L, pivoted, as at M, to a suitable fixed point.

N designates Wires, a portion of which are located in the grooves J, it being understood that one end of each of said wires is provided with a screw-threaded end adapted to receive a nut P, it being further understood that a spring R encircles each wire N and that said springs R are located between the nuts P and a fixed point Q and that the endsof the wires N opposite the screw-threaded ends thereof are secured to a fixed point S.

Y T designates a wheel, in the periphery of which are grooves U and serrations U, and the upper face of said wheel T'is *provided with ratchet-teeth V, with which engages one end of a lever or beater W, pivoted, as at W, to a fixed point.

It will be noted that a portion of the wire N occupies a position between the beater W and the comb formed by the ring E and pins F for a purpose hereinafter described,

S designates a guide adapted to direct the ends of the wool which project within the circle E to the upper wire N, so that said ends may pass over said wire in order to be depressed by the beater W, as best seen in Figs. 2 and X designates a guide located adjacent the ring G and whose object is to direct the ends of the wool which project outside the ring G to the upper wire N, so as to be depressed by the beater L for a purpose hereinafter described.

A designates a drawing-off roll to which motion may be imparted in any suitable manner, it being noted that said roll A is journaled in a box 0', which is adapted to slide in a frame 13 for a purpose hereinafter described. Bearing against said box 0 is a screw D, a portion of which is encircled by a spring E, which is located between one end F of the frame B and a cross-head K secured to the screw D and adapted to slide on the frame B, so as to normally retain the drawing-off roll A close to the drawing-off roll J adjacent thereto.

F designates an endless apron which passes around the drawing-off rolls A and GR, it being noted that an endless apron H is located adjacent the apron F and is passed around the drawing-off rolls J X and operates in conjunction with the apron F for a purpose hereinafter described.

It is to be understood that the ring G within the upper portion of the ring E (seen in Fig. 1) works in conjunction with drawing-off rolls, belts, wires, &c., similar to those described in connection with the ring G within the lower portion of the ring E.

The slivers fed from the boxes O are in-:

serted between the pins F and H by a dabbingbrush L The operation is as follows: The ends of the slivers C are led from the balls D to and through the feed-boxes G and are placed by hand over the pins F and H a short distancein advance of the dabbing-brush L so that when said slivers O reach a point beneath said brush the latter in its up-and-down movements will force the ends of the slivers between the pins F and H,- so that said ends will be carried around by the rotation of the rings E and G, it being understood that the creels D move around with the ring E. The rings G do not move around with the ring E, but rotate on a stationary axis, thereby causing the ends of the wool inserted between the pins F and H to separate, as indicated at a in Fig. 1. The ends of the wool which proj ect outside the ring Gare carried around by said ring and are caused to pass over the wires N and are depressed by the beater L, so as to cause said ends to hang in a vertical plane in order to be caught between the wires N and periphery of the wheel H in a manner similar to that seen in Fig. 5. The wheel H in rotating will cause the long strands of wool or tops to be withdrawn from the pins H and will convey said tops to the apron LP, and when said tops are brought by the rotation of the wheel H to a point where they are no longer held between the wires N and the periphery of the wheel H said tops are conveyed by the apron 11 to the space between it and the apron F, where they unite with the tops that are withdrawn from the pins F by the wheel T, as seen in Fig. 1. The ends of the wool which project within the ring E are di rected to the upper wire N by the guide S and are bent down over the same by the beater V, as seen in Fig. 3. The ring E in rotating will cause the ends of the wool which are carried around thereby to become caught be tween the periphery of the wheel T and the wires N, and the wheel T in rotating withdraws the long strands of wool or tops from the pins F in the ring E, causing said tops to become separated from the wool in the ring E at a point indicated at b in Fig. 1. \V-hen the wheel T in rotating brings the tops carried thereby to a point where they are no longer held thereon by the wires N, said tops are drawn off the wheel T by the apron F and are conveyed by the latter to the space between it and the apron I-I where they unite with the tops delivered by the apron H and are carried oif between said aprons F and ll to any desired point, as at c, in Fig. 1. The short wool 0r noil is carried around by the ring G, from which it is removed in the usual way, so as to leave the pins 11 free to receive a subsequent supply of ends of wool, as hereinbefore described.

The manner of drawing the slivers through the feed-boxes C, so as to obtain the required length of fringe to be fed to the several combs,

is accomplished in the usual way.

Motion is imparted to the aprons F I'I respectively, in any usual or preferred manner, as from one of the rolls G or J and the roll A may receive motion from the belt or apron F thus driven.

The spring R yields when an extra thickness of tops are being drawn between the wires N and wheels H and T, thereby preventing injur to the wool. When an extra thickness of tops is being drawn off by the aprons F and H the spring E yields and prevents injury to the wool.

By the employment of my invention I am enabled to increase the capacity of the machine and to obtain a much greater product than has heretofore been obtained.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a wool-combing machine, in combination with devices for feeding the wool, a rotatable comb-ring, a stationary guide adj acent thereto and adapted to receive the wool ends, a rotatable member contacting with said guide to draw the wool from said combring, and drawing-off devices adjacent said guide and rotatable member.
