WOOL-COMBING MACHINE,

SPECIFICATION forming part of Letters Patent No. 597,361, dated January 1 1, 1898.

Application filed June 2,1897. Serial No, 639,088. (No model.)

To FLZZ whom, it may concern.-

Be it known that I, EDWARD LODGE, of Lymansville, in the county of Providence and State of Rhode Island, have invented a new and useful Improvement in Wool-Oombing Machines 5 and I hereby declare that the followingis a full, clear, and exact description of the same, referencebeing had to the accompanying drawings, forming part of this specification, I

This invention has reference to an improvement on circular wool-combing machines in which the fiber is supported on an annular revolving comb-ring and is combed out, usually by two smaller revolving annular worklug combs placed at opposite sides of the machine within the larger annular comb, to be formed into a continuous uniform sliver.

In this kind of wool-combing machines the short fiber or noil is not as perfectlyseparated from the longer fiber as is desirable and the wool is usually submitted to a second combing in the same or similar machine.

The object of this invention is to secure a more perfect combing out of the fiber and a more complete separation of the noil from the longer fiber at one operation; and to this end the invention consists in the application to the usual circular wool-combing machines of preferably two auxiliary annular rotating combs by which the fiber is combed and drawn out, so that the noil or entangled short fiber will extend within the usual annular working combs rotating inside of the large outer annular comb, so that in drawing off the heard or long fiber to form the fleece the noil will be retained, as will be more fully set forth hereinafter.

Figure 1 is a top view of a sufficient part of a circular wool-combing machine provided with two of my auxiliary annular combs; Fig. 2, a top view of part of the outer annular comb and part of the auxiliary comb, showing the position of the plow-plates for raising the combed-out fiber. Fig. 3 is a side view of one of the plow lifting-plates. Fig.- 4 is a front view, and Fig. 5 a side view, of the dabbin g motion of the auxiliary annular comb.

In the drawings, A indicates the outer and larger annular comb B B, the usual smaller annular working combs; C G, the pinchingrolls that draw the fiber from the large outer annular comb; D D, the carrier-belts; E E, the pinching-rollers that draw or strip the fiber from the annular working combs B B; F F, the twister-heads through which the sliver passes, and G the combed sliver.

The parts so far described are the parts used in the circular wool-combing machines in common use. The annular combs turn in the directions indicated by the arrows, and the machine is driven and operated in the usual manner by imparting rotary mot-ion to the outer annular comb A, which is pro-- vided with a gear-rim on its inner face with which the gears on the outer edge of the working combs B B engage and are thus rotated at the same speed as is the outer comb A.

To this machine I add the annular combs H H, preferably of less diameter than the annular working combs B B, and connect the same with the gear of the outer comb A. From the central column 11 of the comb H the arm 11 projects radially, and on a pin projecting from the end of the arm H just above the wires of the annular comb, the curved plow-plates H are pivotally secured, extending between the rows of the wires or pins of the comb. The lower end of the column H is supported on the step 1-1, and the upper end is secured by the bracket H to the column B in the center of the annular comb B on each side of the machine. The bracket 1, secured to the column 11, forms the support and way for the reciprocating slide 1 of the dabbing-brush I and its operating mechanism, consisting of the shaft i the eccen trio 1 secured to one end of the shaft I and turningin a cup secured to the slide 1'. A pulley I on the other end of the shaft 1 is connected by a belt with the pulley B on the head of the column B. This pulley is driven by suitable gearing from the main drivingshaft B on which the loose and tight pulleys B and B are carried.

The dabbing motion herein described I find to Work satisfactory, but any form of dabbing motion may be used in connection with the auxiliary annular combs H H.

The auxiliary annular combs H H may be driven, in any suitable manner found practicable, in the same manner as the annular working combs B B are driven. In Fig. 5 the auxiliary comb H is shown provided with a gear engaging with the gear on the inside of the large annular comb A.

To enable others skilled in the art to use my invention, I will now describe the same in connection-with the combs of the ordinary circular wool-combing machine.

At or about the points marked X X on the opposite sides of Fig. 1 the wool is fed on the outer annular comb A and is carried toward the auxiliary annular combs H H. Plates H placed between the annular rows of pins forming the comb A, like the plates H raise the fiber up above the pins of the outer annular comb A and above the pins of the auxiliary annular combs H H. At or near the point of nearest contact between the annular combs A and H the dabbing-brush I pushes the fiber which projects inward beyond the annular comb A, as shown in the drawings, into and between the pins of the comb A and the auxiliary combs H H, which, on turning with the comb A, separate and draw out the fiber from the comb A, and at the same time the plow-plates H raise the fiber again above the pins of the auxiliary annular combs H H.

. On examining Fig. 1 it will be seen that the broken line marked a before it reaches the auxiliary combs II H projects inward to the broken line marked a after it has passed the auxiliary combs H H, and that when the fiber reaches the usual annular working combs B B the inner line of the fiber extends over and inside of the annular rows of pins of the combs B, and that as these combs separate from the outer annular comb A the overhanging fiber isdrawn into the annular working combs B B, and it is found in practice that the noil is drawn against and is held by the inner annular row of pins of the combs B B, and that when the fiber is drawn by the nippingrolls E E from the outer sides of the annular combs B B the noil or entangled short fiber is retained and is carried to the lifting-plates K K to be discharged, so that by the use of the auxiliary annular combs H II the wool is combed out and prepared for the usual annular working combs B B, and the operation of these is made far more effective than was heretofore possible and the combing performed by one operation of the machine far more complete. By the use of the auxiliary annular combs about fifty per cent. more combing of the fiber is secured at one operation, and the effect on the cleaning of the fiber is much improved by thus drawing out the fiber and placing the edge of the fiber always containing more of the noil on the inner side of the annular working combs B B and pushing it into the annular rings or pins of the combs by the dabbing-brushes. To secure the best result, the inner of the annular rows of pins should be set closer together than the other rows of the annular Working combs B B, so as to retain the noil more eifectually.

I am aware that prior to my invention circular wool-combing machines have been provided with boxes and a reciprocating drawing-comb operated by complex mechanism to draw out the fiber and partially separate the noil before the fiber reached the rotating annular working comb. I do not claim such mechanism or, broadly, mechanism producing this result. I find in practice that by my construction the auxiliary rotating annular comb secures all the benefits the complex mechanism failed to secure.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. In a circular wool-combing machine, the combination with the outer annular comb and the smaller, inner, annular working comb by which the fiber is drawn inward from the outer comb, of a rotating, auxiliary, inner,annular comb placed in advance of the working comb, and means for rotating the combs to draw the fiber inward from the'outer comb before it is acted on by the working comb, whereby the noil of the fiber is placed on the inside of the working comb, as described.

2. In a fiber-combing machine, in combination, the outer annular comb on which the fiber is fed, the smaller, inner, annular working combs by which fiber is drawn off from the outer comb, the nipping-rolls and carrier by which the fiber is collected, the inner rotating auxiliary annular combs, placed in advance of the working combs and actuating mechanism for rotating the combs by which the fiber is drawn out before it reaches the annular working combs, whereby the fiber is more thoroughly combed and the noil more effectively separated, as described.

3. In combination with a circular woolcombing machine having an outer annular comb, smaller, inner, annular working combs cooperating with the outer comb and the usual nipping-rolls, of a series of lifting-plates in the outer annular comb in advance of an auxiliary comb, auxiliary rotating inner annular combs placed in advance of the working combs, lifter-plates in the auxiliary annular combs, and actuating mechanism, where by the fiber is drawn inward from the outer annular comb and delivered to the annular working combs with the edge of the fiber overlapping the inner edges of the annular working combs, as described.

4;. In a circular wool-combing machine, the combination with the outer annular comb A, the inner annular working combs B B, and the mechanism for stripping the fiber and forming the sliver, of the rotating, inner, annular combs H H operating on the fiber in advance of the working combs B B, the lifting plow-plates H and H and actuatingmechanism for rotating the combs, whereby the fiber is drawn out from the outer annular comb before it reaches the working combs, as described.

5. In a circular wool-combing machine, the combination with the usual mechanism for combing out the fiber and forming the sliver, of the inner auxiliary annular combs H H, the plow-plates H and H and the auxiliary dabbling-brushes l operated substantially in the manner described, whereby the fiber is combed out from the outer annular comb in advance of the working combs, as described.

In witness whereof I have hereunto set my hand.

EDVARD LODGE.
