I i MACHINE FORIWINLING CLOTH ROLLS.

To all whom it may concern:

Be it known that I, ABRAHAM Lf. ADAMS, a citizen of the United States, residing in the city of Bridgeport, county of Fairfield, State of Connecticut, have invented certain new and useful Improvements in Machines for finding Cloth Rolls; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to Awhich it appertains to make and use the same.

iWIy invention relates to machines for winding cloth rolls from wide strips of cloth, and has for its object toI provide a machine of this description in which the top of the cloth roll shall be perfectly free of all tension or other devices so that the operator may have the same under inspection at all times and can easily manipulate the ro-ll backward in order to correct any iinperfect winding or to smooth out any wrinkles or unevenness in the cloth, while at the same time the absence of any weight on top of the cloth roll prevents the latter from sagging; further objects of my invention being toY provide tension rolls which shall always operate against the cloth roll in a horizontal plane at diametrically opposite sides and with equal pressure at all times, and Ato improve generally on the cloth winding mechanism shown and described in Letters Patent No. 878,705, issued to me February 11, 1908.

lVith these ends in view my invention consists in certain details of construction and combination of parts hereinafter fully described and then particularly pointed out in the claims whichA conclude this description. c In the accompanying drawing Figure 1 is a plan View of my improved machine--Fig. 2 a front elevation thereof, and Fig. 3 a sectionat the line a', ai, of Fig. 1.

Similar numerals of reference denote like parts in the several figures of the drawing.

I-Ieretofore, in machines of this description, particularly as exemplified by my patented structure hereinbefore referred to, a tension roll or analogous device has operated with considerable pressure against the top of the cloth roll during the winding process, and this has caused the view of the operator to become obstructed, and has also resulted in the imposing of so much weight on the roll as to causethe latter to sag. Moreover, inequalities or defects in the winding could not be readily detected, and

even when they did become apparent, the cloth roll could not be unwound by backward revolution so as to correct such defects. Furthermore, my improved machine is always under the control of vthe operator since it can be instantly stopped and set in motion by very simple means which will be described hereinafter.

. Several of the elements of my improved machine are common to other prior machines, such as the idle rolls around which the cloth is passed so as to be wound at a proper tension and the provision of the means whereby the paper cop tube is locked to the winding arbor and the cloth secured to said tube in position for winding, and therefore I will not enter into any detailed description of such parts but will merely refer to them briefiy since of course they form no part of my present invention.

1 is the frame of the machine and 2 is the winding arbor provided with a keyway 3 lengthwise of the same.

4; is a sleeve which is pivoted at the top of the frame by means of two diametrically opposite screw bolts 5 that extend from blocks 6 within depressions in the circumference of said sleeve said blocks being secured to the frame, all of which is clearly shown at Fig. `1. The winding arbor 2 eX- tends loosely through this sleeve so as to be capable of free rotation therein and a collar 7 is secured around this arbor in abutment with the edge of the sleeve i so as to prevent the arbor from sliding through the sleeve, and secured to the extremity of the arbor immediately beyond this sleeve is a sprocket wheel 8. The free or other end of i the arbor rests within a journal 9 secured to the top of the frame, said journal being provided with a hinged cap piece 10 which is normally secured to the journal 9 by means of a pivoted hook 11 depending from the cap and engaging a suitable pin 12 that extends' from the journal.

From the above it will be readily understood that by throwing back the cap piece 10 the arbor 2 may be readily lifted from the journal 9 and swung upwardly owing to the fact that said arbor is journaled at the other end within the pivoted sleeve 4, the object of this being hereinafter more fully explained.

While I have just described the journaling of the free end of the winding arbor so that lthe latter can be readily lifted, I do not wish "to be limited to vany particular way of accomplishing this, since there are Vvery many ways in which this vend ofthe arbormight be suitably journaled all of which are` screw is an elongated tube 16 througlr Y which latter the rod 13 extendsfreely.

journaled around the tube 16, and 19 is a sprocket wheel carried by this hub and conl nected to the sprocket wheel 8 by means of vertically disposedbars 36 said bars being an ordinary sprocket chain 20.

21 is the `power pulley whose hub 22 is looselyjournaled on the tube 16 and capable of both rotation and sliding `movements along said tube. rlhe rod 13 extends beyond the hub 22 and a nut 23 is secured to the extremity of said rod in abutment with said hub, so that it will be clear that when said rod is moved inwardly the power pulley 21 will be engaged with the disk 17 which latter may be faced with leather or any other suitable material to facilitate proper frictional engagement, thereby communicating rotary motion to said disk and to the winding arbor 2.

24 is a treadle atV the bottom o f the machine and extending throughout the width thereof, and 25 are obliquely disposed links whose ends are .pivoted respectively to said treadle and to a stationary rod 26 secured to the frame of the machine.

y 27 is a lever whose lower extremity is loosely connected to one end of the treadle by means of alink 28, said lever extending diagonally across the end of the machine with its upper extremity 'terminating in close proximity to the upper portion of the frame 1, said lever being loosely connected a't "29 to the free end of the rod 13, a coil spring I30 being provided whose extremities are secured respectively to said lever and tov the frame of the machine the function of this spring being .to normally throw the lever tow-ard the frame so as to maintain the trea'dle in 'the position shown at Fig. 2 with the links 25 obliquely disposed. W'hen the operator depresses the treadle the links will be thrown toward a vertical plane thereby ythrowing the lever 27 outwardly, the extreme upper end of said lever having a fulcrum against the frame of the machine, and thisl outward -throw of the lever will cause the rod 13 to be shifted so as to bring the pulley 21 in contact withthe clutch disk 17 for the purpose hereinbefore explained;

i when the operator releases the treadle the spring 430 will return the parts to normal position.

31 are elongated bars whose lower extremities are pivoted to the inside of the frame of the machine at opposite ends thereof, and these bars are in pairs, the members 'of each pair extending upwardly in a general -vertical position with their upper Aextremities Von opposite sides of the winding arbor 2.

32 are presser rolls that are journaled between the upper ends of the corresponding bars of each ypair of bars, and 33 are any suitable cords secured at one end to the corv j 1 responding bars of each pair'said cord bev17 is a clutch disk whose hub 18 is loosely ing then broughtover idle pulleys 34 carried by the other bars, t-he lower extremities of .these cords having secured thereto suitable weights 35 which latter are connected by secured to opposite sides of these weights. By providing these connecting bars 36 a suitable support is afforded whereby an aux* iiliary weight 37 may be placed on said bars and slid therealong so that said weight may be applied to any suitable location thereof for the purpose presently tobe explained. From the foregoing it will be clear that these weights will cause the bars 31 to be Vnormally forced toward the winding arbor,

so that when the cloth is wound thereon the presser rolls 32 will always maintain an equal pressure against the sides of the constantly increasing cloth roll, thus leaving the upper half of the roll lentirely freerfor the inspection of the operator. The cloth is passed around suitable rotary tension rollers 38 journaled between the sides of the frame, and is applied to the winding arbor in the manner fully set forth and explained in my prior patent hereinbefore referred to. The bars 31, as hereinbefore stated, are disposed in a generally vertical plane so as to be Yas little influenced by gravity as possible, and the weights 35 at their upper portions are hook-like in shape so that Vthey may be hooked overthe ends of the adjacent tension roller 38, when it is desired to relieve the kcloth ro-ll entirely from compression. The

presser roll 32 that is adjacent to the point on the cloth roll where the cloth is delivered for winding has a rotary movement the reverse of that of the cloth roll itself, so that it will be readily understood that said roll will act as a sort of brake or drag against the cloth roll thus -greatly militating in favor'of even and uniform winding.V I

i 3 9 is a .gage rod secured between the sides of the frame at the front thereof and secured around this ro'dv are adjustable gage collars 40 between whichlatter the cloth( is guided and delivered as fast as wound. The operator places his hands upon the cloth at any suitable point or pointsintermediate of the gage collars care being exercised to prevent thel cloth from riding over4 said collars, or shifting laterally, and shoula any imperfect winding be detected the operator instantlyv ery of the cloth between the gage collars but also for the purpose of simultaneously smoothing out wrinkles during the winding.

I have heretofore stated that the cloth was applied to the arbor 2 in the ,manner set forth in, my previous patent, and as a supplement to this stat-ement I will say that I utilize a pasteboard cop-tube 4l which is slipped over the arbor, in connection with a metal strip 4t2 contained within the keyway 3 and having spurs t3 (only one of which is shown at Fig. 3) which are driven through said tube so as to project beyond the same the cloth being attached to these spurs so that when the arbor revolves the cloth will have a winding engagement. After the end of a bolt of cloth has been secured to the winding arbor the operator depresses the treadle and the arbor will thereupon revolve, and the presser rolls 32 will act against the opposite sides of the oloth roll as fast as it is wound and throughout the entire width of the cloth, thus tending to smooth out any possible wrinkles while at the same time the entire upper half of the cloth roll is open for inspection, so that the operator may at any time place his hands thereon and assist in smoothing out wrinkles or correcting defects in the Winding. Moreover, by the use of my present improvement, there is no extra weight whatsoever imposed upon the cloth roll or the arbor, and therefore there can be no sagging whatever.

It is a fact that some makes of cloth do not have a uniform thickness throughout the area of the cloth, and it therefore sometimes happens that a little tighter compression is advisable at locations on the cloth roll where the abnormal thickness of the cloth has occasioned a. defect in the Winding, and in such instance the auxiliary weight 37 is placed upon the bars 36 at a point substantially below the location of this defective winding, and this will cause the cloth roll to be more tightly compressed at this particular location, thus correcting the defect, and it will of course be obvious that this auxiliary weight can be applied at any point along the bars 36.

The tension at which the cloth-is Wound may be materially increased at any time by placing the hands upon the cloth which of course causes the latter to be wound more tightly, and this is made possible by reason of the fact that the upper portion of the c loth roll is at all times free of all obstructions and open to the inspection of the operator.

A defect in the winding of the cloth some-` times will become apparent only when one or more layers of cloth have been applied thereon, and this may be readily corrected by simply stopping the machine and manually revolving the cloth roll in a reversey direction until the defect is located and remedied, whereupon the machine is again "startetliand the winding' continued.
