CLOTH-GUIDING DEVICE FOR TEXTILE-MACHINES.-

Application filed February '7, 1918.

To all whom it may concern:

Be it known that I, GEORGE BARTON, a citizen of the United States, and resident of ltasthampton, county of Hampden, and State of Massachusetts, have invented an Improvement in Cloth-Guiding Devices for Textile-Machines, of which the following is a specification.

My invention has for an object the guiding of cloth to textile machines which are intended to manipulate and stretch the cloth such as is accomplished in tentering machines, by way of example, whereby the cloth is properly delivered to the cloth clamps on the machine in an effective and positive manner to insure the desired action while in the custody of the tentering machine.

Heretofore in practice considerable difficulty has been found in attempts to feed the selvages of a fabric to the cloth clamps of the reciprocating frames of a tentering machine, in that the said frames are so supported that during their reciprocation they alternately approach and recede from each other, varying the transverse width apart of the two chains of cloth clamps. It is therefore the object of my invention to provide an effective feeding mechanism for the cloth which shall impart to it transverse oscillations commensurate with the reciprocations of the tentering frames and which shall maintain the sel rages in proper alinement with the cloth clamps of the respective frames.

My object is further to provide automatic means foracting upon the selvages of the fabric and controlled by the lateral positions of the selvage edges to cause the cloth to be more or less stretched as to width and positioned transversely, whereby it is accurately guided into the cloth clamps at each side of the machine, with the result that the said clamps shall grip the fabric adjacent to the selvages thereof with accuracy for the better manipulation of the fabric during its stretching and working While-beiug conveyed along the length of the tentering machine.

My invention also consists of improvements hereinafter described whereby the. above objects and results are attained, said improvements comprising certain organization and combination of parts which are Specification of Letters Patent.

Patented Aug. 5, 1919.;

Serial No. 215,818.

fully described hereinafter and more particularly defined in the claims.

For the purpose of illustrating my invention, I have shown in the accompanying drawings the embodiment thereof which is at present preferred by me, since the same is in form to give satisfactory and reliable results, but it is to be understood that the several instrumentalities of which my invention consists, can be variously arranged and organizedand that my invention is not limited to the precise arrangement and organization of the instrumentalities herein shown and described.

Referring to the drawings :Fig. l is a plan view showing my improved cloth guiding means as applied to the receiving end of a tentering machine; Fig. 2 is a side elevation of the same; Fig. 3 is an elevation, with part in section, showing a portion of my improved guiding means on a larger scale; Fig. at is a front elevation of the same; and Fig. 5 is a plan view of the construction shown in Fig. 4.

2, :2, illustrate the receiving ends of the longitudinal frames of a tentering machine. These frames are supported at numerous places along their length by means of horizontal frames 8 journaled at their centers 4; upon suitable standards 4? and having their outer ends journaled at 3 to the under side of the frames 2, 2, whereby the said frames are supported and permitted to have longitudinal reciprocation simultaneously in opposite directions. The oscillation of the supporting frames 3 causes the longitudinal frames 2, 2, not only to reciprocate in opposite directions, but to approach and recede from each other alternately during such longitudinal reciprocations, all of which is well known in connection with tentering machines. Tentering machines are commonly provided with a transverse screw shaft 5 which permits relative adjustment of the frames 2, 2, toward or from each other to suit fabrics of different widths, but such provision need not be specially considered as this is a common expedient in tentering machines. 6 represents chains, and 7 cloth clamps formed thereon. Ordinarily, each link of the chain is provided with a cloth clamp so that these chains in reality constitute chains of cloth clamps, and they are guided longitudinally along the frames 2 and about the guide wheels 6* at the receiving end of the tentering machine. Suitable means is also provided at this end for putting the chains under tension but such details need not be considered as it is a usual construction of tentering machines. While the cloth clamps are conveyed around the guide Wheels 6 the gripping jaws of the clamps are automatically opened by contact with the rim of the wheel 7 which is supported andjournaled concentrically with the aXis of the guide Wheels 6". In this manner the cloth clamps are opened automaticially at. the receiving end of the .tentering frames so as to receive the selvages of the fabric and immediately thereafter grip them. I will'novv proceed to describe in detail my improvements which are applied to the receiving ends of the reciprocating frames 2, 2, of the tentering machine.

To the end of each of the reciprocating frames 2, 2, I secure a bracket 8 which is provided with vertical bearings 9, 9, in which avertic'al shaft 20 is journaled. Secured rigidly to the top of the shaft 20 is a horizontal bearing 11, and similarly secured to the extreme bottom of the shaft 20 is a horizontal bearing 12. The bearings 11 and 12 are parallel. There are similar vertical shafts 2'0 and bearings.1l and 12 in connection with the'bracke'ts 8 of each of the tentering frames. 13 is a horizontal shaft which 'e'Xtends through the bearings 11 at eac'h side of the machine, and at one side the shaftis held against longitudinal adjustment by collars 14 on the opposite sides ofrthe bearing 11, said collars being secured inposition "by being pinned to the shaft (Fig. The other end of the shaft loosely extends through the bearing 11 of the other tenterin'g frame. Parallel to the shaft 13 and journ'aled in the bearings 12 at each side of the machine, is a second shaft 15, and similarly this shaft is held against longitudinal movement by similar collars 1e pinned to it and arranged upon each side of one of the bearings12. The other end of the shaft 15 is loosely held in the other bearing 12 as in the 'case of the shaft 13.

sated fer the shafts 13 and 15 sliding longitudinally through-one set of the bearingsil and 12,as will be more clearly understood by examination of Fig. 1. The shafts 13 and may be free to rotate but this is not essential, as they may be simply smooth guides over which the cloth is guided as in di'c'ated, ,It will be noted that when the 'oscillations of the shafts 13, and 15 take place, they will-necessarily rockthe vertical shafts 20, and this rocking of the vertical shafts provides means for rocking the guider devices which position the selvagcs eorrectly to insure their being properly re ceived by the cloth clamps.

I will now describe the cloth feeders which definitely position the fabric so that the lateral or selvage edges thereof are accurately delivered to the cloth clamps. Each of the vertical shafts 20 is provided with a guider 19, and these latter project inwardly toward the cloth in opposite directions, but in all material respects their relation to and action upon the cloth is the same, and it will suffice to describe in detail one of these devices. Secured to the shaft 20 between the two bearings 9, 9, of the bracket, is a. sleeve 16 fastened in position upon the shaft by means of set screws 17. This sleeve 16 is provided with a. horizontal hub 16 through which a horizontal adjustable rod 21 extends, said shaft being adapted to be socured in adjusted position by means of the set screw 22. The end of the rod 21 adjacent to the cloth has hinged to it at 24 the guider frame 23 so that this frame may be adjusted in a vertical plane, and at the same time may be adjusted transversely of the cloth by the longitudinal adjustment of the rod 21. mechanism for the guider frame gives capacity for universal adjustment. The guider frame 23 is provided. with the two guide surfaces 25 over which the cloth travels. Journaled to the guider frame 23 in front of these guide surfaces 25 is a roller 26 between which and the guide surfaces the fabric passes. 27 is a guider roller which is movable to or from the roller 26, and is arranged upon the opposite side of the fabric so that the fabric is pinched between the two rollers when the roller 27 is moved toward the roller 26. The roller 27 is journaled in a hinged frame 28 carried by the guider frame, and this frame is operated by a suitable motor device 28 controlled by a valve 29 operated by a suitable trip device 30 which provides an arm 30 which extends upward through a slot in the guider plate 25 in position to be acted upon by the selvage of the cloth. In operation, the motor device is actuated by compressed air to move the roller 27 toward the roller 26, and the time of action of this motor devicc is regulated by the valve under the control of the fabric. It Will further be observed that the guider frame is adjusted obliquely to the rod 2] so that the rollers 26 and 27 are arranged at an oblique angle, such that when the fabric is pinched between the two rollers 26 and 27, its upward movement will tend to shift the fabric laterally toward the control arm or finger 30 and toward the cloth clamps. The fabric in traveling upward is caused to act upon the controlling finger 30 and when It is manifest that this adjustable llll the same is moved to the left (Fig. 1), the air pressure is exhausted from the motor to relieve the pressure from the roller 27 to arrest further lateral movement of the eel vage of the fabric. Should the selvage tend to move to the right (Fig. 4:), it will be followed by the finger 30, and this will, through the valve, supply pressure to the motor and cause the roller 27 to apply pressure to the fabric and thereupon through the oblique arrangement of the rollers, the selvage of the fabric will tend to once more move to the left. In this manner, the selvage is guided accurately between very slight variations into the cloth clamps 7 of the tenter frame so that it is properly gripped by said clamps. The particular details of the motor devices for operating the guiders are immaterial to the present invention, but the preferred construction which is employed by me is that which is shown in the patent granted to H. C. Brehmer on December 8, 1914-, and numbered 1,120,019,

It will be understood that the guiders operate on each selvage of the fabric in an independent manner, but the totalwidth of the fabric when in a reasonably stretched condition should just equal the normal distance between the two control fingers 30 of the feeders, and thereafter the fabric might be considered as shifting bodily slightly from one side or'the other, or stretched by action t one selvage or the other, so as to aroperly be fed to both sets of cloth clamps on the twotenter frames. Even if the cloth, passing over the guide shafts 13 and 15, should be more or less loose as to width, the guiders 19 will accurately control the selvages into proper alinement with the cloth clamps, and it will therefore be seen that each guider 19 directly cooperates with its particular associated cloth clamps and tenter frame for laterally positioning the cloth selvage, but both of the guidcrs 19 and the oscillating rods 13 and 15 cooperate in conjunction with taking care of the fabric being fed to the tenter machine and causing it to oscillate in conformity with the oscillations produced upon the fabric in the custodyof the cloth clamps of the tenter machine itself, whereby at all times the fabric is properly fed to the machine and without putting any undue strain upon it at its point of delivery into the cloth clamps. After it has once been gripped by the cloth clamps, the fabric may then be subjected to the various complex stretching operations which are insured by the action of the tenter machine.

I have found it desirable that two transverse guide shafts 13 and 15 be employed, one above and the other below the guiders 19, but I do not restrict myself to the use of the lower shaft 15 as this shaft maybe omitted if the cloth is properly guided from near the floor. Furthermore, it is to be under- &

stood that while it is desirable to feed the cloth upward so that the normal. gravity action of the cloth below the guiders may be utilized, I do not limit myself to this particular arrangement as the parts may be suitably arranged to permit the cloth to be delivered to the transverse guide shaft 13 from the direction found most convenient and suitable. The more essential feature of my invention when applied to ten tering machines, resides in the oscillating shaft 123 moved under the action of the reciprozating tenter frames, and combined with mechanism for oscillating feeders in conjunction with the shaft, but it is to be understood that my improvements are not restricted to the particular character of the machine to treat the fabric after the cloth has been once delivered to the cloth clamps.

It will now be apparent that I have devised a novel and useful construction which embodies the features of advantage enumerated as desirable, and while I have in the present instance shown and described the preferred embodiment thereof which has been found in practice to give satisfactory and reliable results, it is to be understood that I do not restrict myself to the details, as the same are susceptible of modification in various particulars without departing from the spirit or scope of the invention.
