APfABtA'lUS FOR FEEDING AND GU IDIN CLOTH.
Specification of Letters Patent.
Application filed May'5, 191 5; Serial No.,25,894.
1 b all whom it mag concern:
Be it known that I, RUDOLPH M. HUNTER, a citizen of the United States, and resident of Philadelphia, county of Philadelphia,-
and State of Pennsylvania, have invented an Improvement in Apparatus for Feeding and Guiding Cloth, of which the following is a specification;
The object of my invention is to provide a suitable means for feeding cloth to tentering and other textile machines, more especially of the character of what is known in the art as a feeder and guider. In machines of this class, the cloth is maintained taut transversely of its length and guided as it passes between the rolls.
My invention consists of means for controlling the feeding of the cloth when operated by a liquid actuated motor device, said motor device in turn rendered active by compressed air or gas admitted to and exhausted from the motor under the control of a valve, itself controlled by the fabric which is being guided through the machine, all of which is fully set out hereparticularly pointed out in the claims.
My invention also comprehends details of construction which, together with the features above s ecified, willbebetter understood by re erence to the drawings, [in
Figure 1 is a side elevation of my improved feeder and guider with a portion in section; Fig. 2 is a front elevation; and
Fig. 3 is asectional view of'the valve de-' vices of the motor taken on line w-zv of rdi flaril there are one or more pairs of guide rolls for feeding and guidlng the selvages of the woven fabric to the cloth clamps of the tentering machine, but it .will sufiiceto describe a single one of the This frame 2 is provided'with a guide plate 3 over which the cloth is guided, said plate Patented May 11 1920.
having an opening through which the adjustable roll 4 operates. 5 is a rollv arranged above the opening in the plate and is suit ably journaled upon the frame 2. The roll 4 is journaled in a pivoted frame '6, hinged to 'the'frame 2 at 7 and having an operat ing arm 8. This frame 6 is-in general structure a bell-crank lever. The free end of the arm SeXtends downward and rests upon the center disk 13 of the diaphragm. 11, said diaphragm being clamped at 12 in the open top of the motor body 9; Theweight of the roll 4 and frame 6 presses the arm downward and the thrust upon the diaphragm is transferred to the stop 14' in the motor below the disk 13 of the diaphragm. The body 9 forms a reservoir for a fluid, preferably oil, and this 'fluid acts to raise the diaphragm at its center to operate the bell-crank lever frame 6* and the roll 4. This' body part 9 is adjustably clamped at 1i to the main frame 2 so that it maybe adjusted vertically to accurately position the roll t with respect to the roll 5. One end of the body 9 is provided with a chamber 17 rising to a level above the diaphragm, and this chamber may be provided with a sealed inlet 16 through which the oil maybe introduced. When the oil reservoir is properly filled, the level of the oil will extend nearlv to the top of the chamber 17 The body is further provided with a lateral arm 18- having a zontal hole or conduit 24 opening into "the oil. The control valve device 19 has at its upper partia neck 21 which .fits tightly into thehole on-the end of the arm 18 and the valve device is clamped in position by the nut 22. The neck portion and upper art of the valve device are provided wit a port 23 which communicates with the port orconduit. 24 of the arm 18. Within the body of the valve device 19 is a valve piece 20 which is pivoted to rock. The upper end of this valve piece .snu'glyfits the curved wall 19 of the valve casing, and is provided with an air su 1y port 20 and an exhaust channel 20. valve is made hollow as at 20 and is in co munication with the compressed air supply pipe 25. The valve piece is 'journaledhe interior of the rocking- .vertical aperture in its end and. a hori- 1 '90 upper part of the air chamber 17 above the in the casing in any has an axial extenslon 27 which is secured to a bell-crank arm having a counterweight 31 which normally causes the valve piece to rock into position in which the ports 20 and 23 come into alinement to admit compressed air through the port 24 into the air chamber 17, and thereby apply pressure upon the top of the oil to cause the same to exert a pressure against the under I side of the diaphragm 11 and thereby lift the'roll 4 toward the roll 5 for gripping similarly a lowering of the roll 4, this position being indicated in Fig. 1. The oscillation of the valve piece 20 to perform this function is accomplished by the pivoted feeler finger 28 which is pivoted at 29 to the frame 2, and moreover has its upper end extending through the guide plate 3 to be acted upon by the selvage of the fabric passing between the rolls land 5, and having its lower end arranged to act upon the arm 30 attached to the axial extension 27 of the valve piece.
Ordinarily the rolls 4 and 5 are set at a slight angle to, the line of travel of the fabric so that when the fabric is pinched between the rolls, while being drawn between them, the tendency will be to stretch the fabric transversely. This action takes place normally by the action of the rolls 4 and 5 under the influence of the compressed air. Whenever the selvage of the fabric strikes the feeler finger 28, it oscillates the latter and throws the valve piece 20 into the exhaustingposition 5*ig.1"3). The air pressure then being cutg ifofi' to the motor device and the pressurefl'therein rel eved, the roll at drops sufficiently to relieve the bite upon the fabric which tends to contract laterally. These actions take I place automatically so that the width of the fabric remains approximately the same.
The particulardevice shown may be materially varied in construction, and I do not restrict myself to any particular character of valve, but have shown a type of valve which has been found well adapted to the purpose of this invention. The general construction may be more or less varied without departing from the spirit of the invention, and 1 therefore do not restrict mvself to the minor details. l
