FEED FOR CARDlNG-ENGINES.

SPECIFICATION forming part of Letters Patent No. 766,486, dated. August 2, 1904.

Application filed January 15, 1904. Serial No. 189,127. (No model.)

To all whom! it WHY/U concern:

Be it known that I, COLONEL Moses BARB ER, a citizen of the United States of America, residing at Monson, in the county of Hampden and Commonwealth of Massachusetts, have invented a new and useful Feed for Caroling-Engines, of which the following is a specification.

My invention relates to improvements in feed mechanism for first and second breakers and finisher-cards in which the tumbler is located adjacent to but out of direct working relation or operative conjunction with the main cylinder and a small cylinder and a dofl'er or feeder are introduced between said tumbler and main cylinder, theweb being fed to the latter for the first time by such dofl'er or feeder, an arrangement which under ordinary conditions necessitates the placing of the small cylinder and dofl'er or feeder above the tumbler and generally the axis of one or both in advance of the axis of the tumbler. The exact relative positions of these axes neednot be maintained, however, when it is desirable or expedient to change the same, provided the general arrangement of parts is not radically departed from, and it is possible to conceive of a structure wherein the small cylinder and dofi'er or feeder might be located below the tumbler; but it is believed that no such structure would be practical. In addition to the foregoing .1 may use one or more workers, two generally being suflicient for the best results. When two workers are employed, one operates in connection with the tumbler and small cylinder and the other with the small cylinder and doffer or feeder.

The object of my improvementis to provide a feed of the class specified which increases the amount of material that can be successfully handled by a given machine in a given time and improves the quality of the drawing or roving, as the case may be. The increase in quantity and improvement in quality'may each ordinarily be reckoned as high as twentyfive per cent. and in some cases even thirtythree and one-third per cent. or more. The increased production results from the accelerated speed which it is possible to give a machine equipped with my feed mechanism, and the improved quality is brought about by working the lumps out of the web and getting the same into good conditionthat is, making an even web of itbefore' delivery to the main cylinder. Amachine provided with this feed mechanism can be run at least twentyfive per cent. faster than one without it and will successfully handle a lower grade of stock for a given size of yarn, thereby lowering the price of production still more.

A further object of my invention is to provide practicable and efficient feed mechanism with which to accomplish the above-mentioned object which is simple and comparatively inexpensive and may be applied to an old as well as a new machine, such mechanism being of such nature as to only slightly increase the length of the machine to which it is applieda very valuable consideration when it is necessary to economize floor-space, as frequently occurs.

Heretofore it has been necessary to run the breakers and the finisher-card at a comparatively low rate of speed, and the web could not be worked down in either or all of the machines to the degree of evenness needed to produce the best results, but would be more or less lumpy and rough after passing through the machine or machines, at least very much more uneven than when my feed is used, which successfully overcomes these disadvantages.

I attain these objects by the mcchan ism illustrated in the accompanying drawing, which shows a side view of the feed as applied to the main cylinder of a breaker or finisher-card.

It will be understood that the several rotary members, including the main cylinder,are suitably supported or journaled and driven by belts, gears, &c., in any convenient manner, such supporting and driving-means differing more or less in different machines.

Like letters of reference designate like parts.

A portion of the main cylinder of a machine is represented at a, and its periphery is covered with wire teeth or card-clothing b, as are the peripheries of the other rotary members described below. The arrangement of the teeth I) varies, as will be seen referring to the drawing. When the arrangement is such members in the drawing indicate the directions in which said cylinder and members are adapted to revolve. With this cylinder a tumbler 0, leader d,and feed-rolls e and e are employed, as usual, only the members are so arranged as to leave an inch of'space, perhaps, between the tumbler and cylinder, since the former does not now directly deliver the stock to the latter.

In addition to the old members just described a cylinder f, herein termed small or auxiliary cylinder to distinguish it from the main cylinder a, is provided, also a doifer g, which is also a feeder. The cylinder f operates in conjunction with the tumbler 0 and the doifer and feeder g in conjunction with both cylinders f and a. The teeth 6 on the tumbler 0 and the cylinder f are arranged point to back, and the same is true of the teeth on said cylinder and the doffer and feeder g.

It is generally preferred to employ two workers it and it with the small cylinder, al-

though one or both may sometimes bev omitted without disadvantageously affecting the desired results to too great an extent, and, on the other hand, more than two may be introduced into the mechanism if it is found to be advantageous to do so; but 1 have found by experience that two workers arranged as shown that is, in operative conjunction with the tumbler and doffer and feeder, as well as with the small cylindergive entire satisfaction. The teeth 5 on the cylinder f and each ofthe workers 71 and 7a are arranged point to point, while the teeth on the worker h and the tumbler 0 are point to back, as are those on the worker 72/. and the doifer and feeder g. I

The dotted lines and 7' indicate the positions of the first worker and its stripper, respectively, of the machine, which worker and stripper form no part of this invention and are referred to merely for the purpose of showing that the new mechanismcan be appliedwithout disturbing such members when they are located asusual. Inshort, the only alteration required to attach my mechanism to an old machine other-than providing suitable bearings for the new parts is to move back the tumbler, leader, and feed-rolls about an inch or replace the old tumbler with one x which is aninch or so smaller.

Some idea of the relative speeds ofthe different rotary members may be gathered from the following; but it is to be distinctly understood that such speeds must vary considerably in different machines and for difierent grades of stock.

Assuming that the main cylinder a makes one hundred and twenty revolutions per minute,the auxiliary cylinder f should make about two hundred and sixty, the tumbler 0 about one hundred and thirty, .and the doffer and feeder 9 about four hundred and fifty. The worker It may make some twelve revolutions per minute and the worker 72. perhaps not more than eight. The feed-rolls e and e revolve very slowly, the speed varying according to the weight of stock per yard which is to be run between them. The leader (Z runs faster than the feed-rolls, but not so fast as the tumblerabout one hundred and fifty revolutions.

The numbers on the drawing designate the approximate surface speeds of the several members upon which such numbers appear, the calculations being based upon the figures given in the preceding paragraph and the sizes of the members, which latter can be readily ascertained when it is known that the drawing is about one-eighth full size. Although relatively correct, at least approximately, these speeds will of course greatly vary, and I do not desire or intend to be unduly restricted to or by them.

The general operation of my feed mechanism will :be understood from the foregoing, especially if reference be had to the heavy broken line in the drawing, which marks the courseof the web; but a brief detailed description will be here given, first without considering the workers it and h, which, as has already been remarked, may be omitted under some conditions. The stock is drawn between the feed-rolls e and e and delivered to the tumbler 0 by the leader d in the same manner as heretofore; but instead of delivering the web of stock, which is now lumpy, coarse, and uneven, directly to the main cylinder a the tumbler 0 delivers it to the small or auxiliary cylinder f, which has a much more rapid surface speed than said tumbler. The small cylinder f in turn delivers the web to the fasterrunning doffer and feeder g, and the rapidlyrevolving main cylinder a receives said web from said dofler and feeder. From this point on the web takes the usual course and receives the usual treatment. By the time the web reaches the main cylinder the lumps have been pretty thoroughly workedout and it is finer and more even, thereby producing a better grade of yarn than formerly, owing tothe treatment which my invention provides. Furthermore, the time required to produce this improved yarn is greatly reduced by the new feed.

Thereductionof the stock ,to proper condi-' tion must be done before it is delivered to the main cylinder, because after such delivery there is no opportunity or provision for thoroughly and speedily doing this work. Consequently it is generally found to be expedient to employ the two workers it and 7a, which split the web twice between the tumbler c and the dofl'er and feeder g. The worker it takes the web, or a portion of it, from the auxiliary cylinder f and returns it to the tumbler c, which delivers it again to said cylinder, and the worker h takes from the cylinder and delivers to the doffer and feeder g, which delivers the now united splits to the main cylinder 0. The slow-running workers operating with the comparatively fast-running members 0, f, and augment the effectiveness of the latter and enhance the efliciency of the feed.

Although I have shown and described a preferred form and arrangement of my feed, it is obvious that more or less change therein may be make without departing from the nature of my invention, and I desire to include in and cover broadly by my claims any and all departures from such form or arrangement, variations in size or speed of members, and other changes which fairly fall within the scope of said invention.
