JOHN T. BOLTON, OF NEW HAVEN, CONNECTICUT.

FABRIC-GUIIDING MECHANISM.

Application filed March 24, 1922. Serial 1T0. 546,248.

To all whom it may concern: Be'it known that I, JOHN T. BOLTON, a citizen of the U nitcd States, residing at New Haven, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Fabric- Guiding Mechanisms, of which the following is a specification, reference being bad therein to the accompanying drawings.

This invention relates to new and. improved fabric guiding mechanism, referring more particularly to mechanism for controlling the movement of .a piece of fabric so that it may be uniformly rolled, each convolution of the rolled fabric being exactly over the precedingconvolution, thus leaving one end of the roll flat.

It is the object of this invention, among other things, to provide a'device of the character mentioned with a view to compactness, in which the number of parts are few, the construction simple, cost of production small, and efiiciency and operation high.

The improvements in the details and arrangements of parts will be apparent from an inspection of the accompanying drawings in connection with the description hereinafter contained, and wherein a preferred embodiment of the invention is disclosed for the purpose of imparting an understanding of the same.

In the drawings, wherein like characters of reference designate like parts in the several figures;

Figure 1 is a front elevation, partly in section, of my improved mechanism;

Figure 2 is a transverse sectional view thereof, taken generally upon line 2-2 of Figure 1;

Figure 3 is an enlarged fragmentary detail of a portion thereof, taken generally upon line 33 of Figure 1; and

Figure 4 is an enlarged plan of the movable cam and someof its adjacent mechamsm.

It is desirable in winding fabric Whether taken from roll, a box, or other device where it has been folded or plaited, that the ends of the completed roll should be flat and smooth and that in the winding operation the lateral position of the fabric be maintained in auniform path so that such a result may be obtained. Efforts have been heretofore made to bring about such desirable roll winding, but so far as at present advised, these attempts have always been confined to mechanisms that contact with the fabric near the edges only and sometimes with an independent and supplemental de vice located lherebetween, and these have usually been arranged at an angle to the width of the fabric. In practice, this type of mechanism has been found quite ob1ectionable, especially with some classes off-abric, because in their operationthe pressure is only applied where the mechanism contacts with the fabric, this distorts the sha c of the fabric, produces a gathering, a oneliling fold or a wrinkle in the fabric adjacent to the edges thereof, which frequently remains and cannot be readily smoothed 'or ironed. out. Obviously, .with fabric of very fine l'GXtUIQ/OT having a print or figure thereonor therein, such distortion is especially objectionable. Then again, with such mechanism, each of the devices is separate and independent of every other one and must be arranged in a predetermined osition relatively to each other, frequent a dlfficult task.

All of these, and other objections, that are known to those versedjn the art, are overcome in my improved mechanism, wherein the device is self contained,,in that it'is a single unitary structure provided with a plurality of members that successivel 0on tact with and are in part controlled y the fabric throughout substantially the entire width thereof, and apply. a lateral pressure that is exerted throughout the entire width by the sleeve 13 and are held against endwise movement by the collars -14. v

Located equally distant about the axle of the shaft 11 are a plurality of rods 15, each being provided with a shoe 16 at each end with a cam lug 17 thereon. All of the shom at one end of the rods 15 are connected with oneof the reel heads 12 by links {18 that are hinged atone end to the shoes y the pins 19 and at the other end to the reel head by the pins 20. The links are held against lateral movement by the lugs 21 thereon that pass through radial slots 22 in the flange of the reel head 12. These several rods 15, constructed and associated with the reel heads 12, as above described, move in a rotary path about the shaft 11 and are capable of a synchronous movement parallel with the axis of said shaft.

Each of the rods 15, may, if desired, provided upon their outer faces with a friction member 23, which may be either of wire cloth, rubber or other similar device that will grip the fabric and hold it in contact therewith. As shown in Figure 1, this friction member 23 extends the entire length of each of the rods 15, but it may be shorter if so desired.

Adjacent to the inside of each of th standards 10 and fixed in relation thereto are the frames24, upon each of which is a projecting lug 25 within which is fixed the

rods

26 and 27. Upon the inner face of one of the frames is a cam 57 and pivotally connected to the other frame 24 by the pintle 58 is the movable cam 28 having a cam face 29 thereon, and a slotted arm'30.

The reel, composed of the reel heads 12, rods 15, and connecting mechanism, is rotated in the direction of the arrow in F i ure 2 by the fabric designated 59 traveling in the same direction. A lateral movement of the bars 15, that is, parallel with the axis of the shaft 11, is accomplished by engagement thereof with the cam 57 at one end and by the movable cam at the other end, and when out of contact therewith the bars travel only in a rotary ath being held against endwise movement by the substantially parallel inner faces of the frames 24, substantially as shown in Figure 1. The space between the ends of the lugs 17 on the opposite ends of the rods 15 is slightly less than that between the parallel inner faces of the frames 24 so that no friction is created by their otherwise constant contact therewith. The position of the cam 28 is such that the lug 17 contacts with the cam face 29 when the same is traveling through a rotary path at the top of the reel, at which time this particular rod 15 is out of contact with the fabric. The lug 17 at the opposite end of the rod is opposite the low face 31 adjacent to the cam 57 upon the frame 24. This rod, moved as above described, to the left in Figure 1, is, it will be remembered. constantly rotating and is thus brought into contact with the fabric 59 (see Figure-2) in its laterally extended position. As soon. however, as the rod contacts with the fabric, the shoe 16 thereon op osite the cam 28 engagesthe cam 57 an the rod is moved axially during its rotary travel to a position wherein the said lugs will pass between the parallel faces of the frames 24, during which time the fabric is moved laterally therewith. Thereafter the fabric travels in this new path and is taken off the reel onto a rollor such other device as may seem necessary or desirable. When the rods 15 of the reel move in the same rotary path no lateral movement is imparted to the fabric, but contra when the rods are actuated axially. This lateral movement of the fabric is controlled in my device automatically by the fabric itself, by mechanism about to be described.

Adjustably secured in one of the standards 10, is an air plug 32 having an air chamber 33 therein and atfixed thereto is the ca 34, between which and the plug is a flexible diaphragm 35, connected with the cam 28 by the link 36.

Leading into the air plug 32 is an inlet pipe 37, which connects with a port 38 that extends from the chamber 33. This pipe 37 extends from a union 39, joined by a pipe 40 to a vacuum cylinder, not shown. \Vhen the vacuum is maintained the diaphragm 35 is flexed downwardly and through the link 36 moves the cam 28 upon its pivot mounting, lifting the cam face 29 upward and out of the path of the lugs 17 so that the same passes thereby without contacting therewith. The means for automatically controlling this vacuum comprises a bracket 41, which is movable upon the rod 26 and held against rotary movement thereon by itsengagement with the rod 27 (F igure 3). In this bracket is a rock shaft 42 having a block 43 fixed thereon, within which is secured a rod 44 having an adjustable weight 45 thereon and a trip arm 46 terminating at its lower end in a contact finger 47, that projects upon both sides thereof a substantial distance so as to be entirely certain that it will be engaged by the moving fabric.

Also fixed on the rock shaft 42 is a closure plate 48 having a stop arm 49 connected therewith.

Secured in the bracket 41 by any referred means, is a pipe 50 formed wit a curved end 51, which terminates a slight distance in advance of the face of the closure plate 48 when the stop 49 is in contact with the bracket 41, as shown in Figure 1, thereby leaving a slight space 52 therebetween. A flexible tube 53 connects the pi e 50 with the union 39 preferably throu arigid pipe member 54. This flexible tu 53 is provided so as to accommodate the movement of the bracket 41 along the

rods

26 and 27 and be operative in any one of such adjusted positions. This bracket 41 may be secured in any of its adjusted positions by a screw 55 or the like, or it may be held in its adjusted positions through a connection with another co-operating mechanism and a stud 56.

The weight 45 is so adjusted upon the rod 44 as to actuate the rock shaft 42 and maintain the end of the stop fin er 49 against the bracket 41, thus leaving t e open space 52 in front of the curved and of the pipe 50. When the parts are in these relative positions there is no vacuum in the air chamber 33, the same being destroyed by reason of the leakage at the open space 52, at which time the weight of the movable cam 28 is such as to cause it to occupy its down position, substantially as shown by full lines in Figure 4. The cam 28, now being in the path of movement of the lugs 17, will impart lateral movement to the rods 15 as above described. When lateral pressureis applied to the contact finger 47 the closure plate 48 is actuated so as to'move the face thereof into contact with the end of the pipe 50, thus closing the space 52 and sealing the vacuum system. The movable cam 28 is now actuated through the movement of the diaphragm 35 and lifted out of the path of said lugs, thus permitting the several rods 15 to travel in a uniform rotary path, at which time no lateral movement is imparted to the fabric on the reel.

As the position of the bracket 41 is adjusted so that the finger 47 rides against the edge of the fabric, it is obvious that when the fabric is traveling in a correct path the vacuum system is closed, the movable cam 28 is out of the path of the several rods 15 and the fabric continues to travel in its defined correct path-.- If, however, the fabric does not contact with the finger, as above indicated,- there is no pressure thereon, the rock shaft 42 is actuated through the weight 45 and the stop arm 49 is brought up against the end of the bracket 41, thus destroying the vacuum. The weight of the cam 28 now causes it to move downwardly and in its then position moves the rods 15 successively parallel to the axis of the shaft 11, which rods then automatically as they contact with the fabric-move the same'laterally until it is again brought into contact with the finger 47, when pressure being then applied thereto, the vacuum system is sealed, t e cam 28 is lifted and the fabric continues to travel in its predetermined path as before. As each successive rod, when it contacts with the fabric exerts a slight lateral pressure thereon, a very extended lateral movement may be applied 'to the fabric, if necessary to bring it into contact withthe finger 47. As the rods 15 contact substantially through the entire width of the fabric, it is obvious that no portion thereof is distorted, and as the mechanism is entirely automatic in its operation, the results obtained are obviously certain, fixed and definite, and the efliciency of the device extremely high, while the mechanism itself is quite simple in its character and is easily constructed and readily assembled, and when so assembled not liable to be easily disarranged or get out of order.

As shown and described herein the movable cam 28 is lifted out of the path of the lugs 17 by the diaphragm through the 'action of the vacuum thereon. Obviously the connection between the diaphragm and movable cam may be so arranged however that the reverse movements will result, that is, the vacuum through the diaphragm will hold the movable cam in its down position in the path of the lugs 17.

There are minor changes and alterations that may be made within my invention, aside from those herein suggested, and I would therefore have it understood that I do not limit myself to the exact construction herein shown and described, but claim all that falls fairly within the spirit and scope of the appended claims.
