FEEDING DEVICE FOR CARDING-MAGHINES.

Specification of Letters Patent.

Patented Dec. 6, 1910.

Application filed July 1, 1909. Serial No. 505,364.

To all whom it may concern:

Be it known that I, Eono V. BATES, a citizen of the United States, residing at Lowell, in the county of Middlesex and State of Massachusetts, have invented a new and useful Feeding Device for Carding-Machines, of which the following is a specification.

This invention relates to a feeding device particularly adapted for finisher wool-cards.

The principal objects of the invention are to provide a feeding device of such construction that the stock will be more thoroughly evened up and the fibers more thoroughly arranged in parallel position than has been the case heretofore, so that all the lumps will be broken up and the stock fed to the main cylinder in a thin, even, unbroken web.

Another object of the invention is to provide means for delivering the stock to the main cylinder in such a way that the speed of the delivery rings can be increased, thereby securing a larger production than can be obtained with the old way of feeding, and to provide a better and stronger yarn with less waste.

Further objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanying drawing, in which the figure represents a well known form of finisher wool-card in elevation with a preferred embodiment of this invention applied thereto in place of the ordinary licker-in and tumbler.

The invention is shown in the present instance as applied to a finisher card having a main frame 10, a main cylinder 11, and feeding in rolls 12. Mounted on a rearwardly extending bracket 13 of the main frame is a casting 14 which can be placed on any finisher card without disfiguring the same, and which supports the entire feeding arrangement, so that this invention can be applied to all kinds of finisher wool-cards in place of the old feeding arrangement. Mounted adjustably on the casting 14 is a shaft 15 carrying a cylinder 16 constituting the licker-in. As ordinarily constructed the lickers-in have been made of small diameter, say 4% to 5 inches and some trouble has been experienced by the fact that long fibered stock will almost entirely wrap around them so that it catches in and is not thoroughly removed therefrom. In order to avoid this and secure a more perfect evening of the stock this licker-in is shown as of a comparatively large diameter, preferably 9 or 10 inches. It is also shown as running in the opposite direction from that which is usual. That is, its surface engaging the feeding in rolls moves downwardly as it passes them. Located directly between the licker-in and the main cylinder is a fancy 17, which, at the surface which engages the licker-in, runs upward in the same direction as that surface of the licker-in. This fancy is adjustably mounted in bearings on the casting 14:. It will be seen that the fancy comes close to the teeth of the main cylinder so that any stock remaining on the fancy as it rotates will be removed directly by the main cylinder. This prevents clogging the fancy and keeps it clean.

Located over the licker-in and mounted in adjustable bearings 20 on the casting 14: is a dofier 21 which takes the stock from the licker-in after it has been raised by the fancy. The stock passes around the doifer and is taken therefrom by a stripper 22. An important feature of this part of the invention is the fact that the stripper and dofier teeth meet point to point so that the stripper, which rotates much faster than the doifer, is extremely eflicient to straighten out the fibers and arrange them in parallelposition. For this purpose the doffer rotates to the right and its teeth project backwardly while the stripper rotates to the left and its teeth project forwardly as is indicated by the arrows. course rotates much faster than the doffer and engages the main cylinder which takes the stock from the stripper. Rotating in contact with the doffer is a small clearer roll 23 having about the same circumferential speed as that of the dofi'er, or a little greater. This cylinder rotates so as to take any stock from the doffer that may be left by the stripper 22. As its teeth project forwardly and as it rotates to the right the stripper will strip this small roll so that substantially all the stock on the doifer is transferred evenly and uniformly to the main cylinder.

It will be observed also that the fancy The stripper of being located directly between the licker-in and the main cylinder and rotating upwardly from the llCliQY-lll over to the main cylinder, and the doffer, stripper, and clearer being located above the fancy so as to cover all the space from the liclrer-in to the main cylinder, the lint which is always whipped up by the fancy cannot be deposited outside the machine, but must be caught either by the fancy, the dofier, the stripper, the clearer, or main cylinder. This is a point of advantage as it eliminates the necessity for providing for collecting and cleaning up this lint which ordinarily is set free by a fancy.

In machines employing ordinary forms of feed devices it has been found in practice that when the web is separated the advancing end of the new web will be forced into the teeth of the main cylinder so that it can not be thoroughly removed by the various workers 25, and consequently it is raised by the fancy 26 as a lump, and it is taken up in that way by the delivery rings 27. In this way it goes into the product as an irregularity. By the employment of the principle set forth herein this is entirely avoided, as the preliminary working of the stock before it reaches the main cylinder prevents any material lump being formed in the first place upon the teeth of the main cyl i n d er.

On account of the improved preparation of the stock explained herein the delivery rings can be operated faster than has been the case with the old forms of feeding devices, so that the production can be increased by a material percentage. served also that the cylinders 16, 17, 21, and 23 are all carried by the casting 14- which fits the space ordinarily occupied by the licker-in or tumbler so that this feeding device can be placed in position on an ordinary finisher card without reconstructing or mutilating any part of it.

IVhile I have illustrated and described a preferred embodiment of the invention I am aware than many modifications may be made therein by any person skilled in the art without departing from the scope of the invention as expressed in the claims. Therefore I do not wish to be limited to all the de" tails of construction shown or described herein, but

hat I do claim is 1. In a card, the combination with the main cylinder, the feeding-in rolls, and a licker-in running in contact with the feeding-in rolls, of means for transferring the stock upwardly from the licker-in to the main cylinder. and means separate from said first mentioned means for transferring stock from the licker-in to the main cylinder, and for raising the stock on the licker-in located below the first named means, and be It is to be ob-- tween and in contactwith the licker-in and main cylinder.

2. In a card, the combination with the main cylinder, the feeding-in rolls, and a liclrer-in, of a fancy for raising the stock on the licker-in running in contact with the main cylinder, and means for transferring the stock from the licker-in to the main cylinder located in position to collect all flying lint set free by the fancy except that which falls back on the fancy.

3. In a finisher wool-card, the combination with the main cylinder and the feedingin rolls, of a licker-in of relatively large diameter for taking the stock from the feed ing-in rolls, a stripper engaging the main cylinder, means for taking stock from the licker-in and transferring it to the stripper, said means comprising a roll having teeth meeting the teeth of the stripper point to point and a fancy engaging the main cylinder and lickerin and located below the stripper.

4. In a finisher card, the combination with the main cylinder and feeding-in rolls, of a licker-in located in position to receive material from the feeding-in rolls, a fancy for raising the stock on the licker-in, extending therefrom to the main cylinder, 21 doffer located above the licker-in and fancy and having its surface moving in the same direction at its point of contact with the licker-in, and a stripper for delivering stock from the doft'er to the main cylinder, the teeth of the stripper and dotter being arranged to meet point to point,

5. In a finisher card, the combination with the main cylinder and feeding-in rolls, of a licker-in located in position to receive material from the feeding-in rolls, and rotating so that its surface next to the feeding-in rolls moves downwardly with its teeth projecting forwardly with respect to its direction of rotation, a fancy located between the main cylinder and the licker-in and in contact with both the liclrer-in and main cylinder for raising the stock on the licker-in, a doffer located above the licker-in and fancy and having its surface moving in the same direction at its point of contact with the licker-in, and a stripper for delivering stock from the do'lfer to the main cylinder, the teeth of the stripper and doifer being arranged to meet point to point.

6. In a finisher wool-card, the combination with the main cylinder and the feeding-in rolls, of a licker-in in contact with the feeding in rolls and arranged to move downwardly at its points of engagement therewith, a fancy directly between the licker-in and the main cylinder arranged to raise the stock on the licher-in and in sucn position that the teeth of the main cylinder will take any projecting stock therefrom and means for transferring the stock from the licker-in on to the main cylinder above said fancy, my hand, in the presence of tWo subscribing whereby the fancy will catch any material Witnesses.

dropped from said transferring means and the flying lint set free by the fancy wi ll all EDDO BATES 5 be collected and transferred to the main oyl- Witnesses:
