AUTOMATIC CLAMP FOR TEXTILE MACHINERY.
SPECIFICATION forming part of Letters Patent No. 571,508, dated November 17, 1896.
' Application filed June 8, 1896. Serial No. 594,695. (No model.)
To all whom it may concern.-
Be it known that I, HARRY W. BUTTER- WORTH, of the city and county of Philadelphia, and State of Pennsylvania, have invented an Improvement in Automatic Olamps for Textile Machinery, of which the following is a specification.
My invention has reference to automatic clamps for textile machinery; and it consists of certain improvements, which are fully set forth in the following specification and shown in the accompanying drawings, which form a part thereof.
Myimprovements comprehend certain constructions of a clamp adapted to textile-machines, and especially to tentering-machines, which shall have capacity for a portion thereof being turned out of the way to permit the ready passage of the fabric into the clamp, and then automatically adjust itself for the proper gripping or clamping of the edge of the fabric. The special application of my improvements to tentering machines will make the advantageous features of my im provements more apparent. In tentering-machines the edges of the fabric have heretofore been inserted by hand. The clamps, as heretofore made, have been impractical to permit the fabric to be inserted automatically within the grasp of the clamp, because the upper jaw of the clamp cannot secure a position above the fabric in passing about the end cylinders of the machine. By my improvements I support the gripping or upper jaw of the clamps upon a movable frame carried with the lower jaw, and combine therewith automatic locking devices which look or unlock the lower jaw and movable frame relatively in position at or about the time the clamping operation takes place. In this manner the upper part of the clamp is thrown back and permits the lower jaw to readily pass under the fabric, after which by a suitable guide the upper part of the clamp is turned down into position and locked and the upper gripping jaw thrown into action to grip the extreme edge of the fabric. It is customary in practice to form these clamps upon links of a chain, so that there is a series of the clamps hinged together, though my invention may be employed in other connections than with the chain-clamps.
. My improvements will be better understood by reference to the accompanying drawings, in which- Figure 1 is a plan view of the link and clamp complete. Fig. 2 is an end elevation thereof. Figs. 3 to 6, inclusive, are end elevations of modifications of the same invention. Fig. 9 is a side elevation of one end of a tenteringmachine. Fig. 10 is an end elevation of a portion of same. Fig. 8 is a perspective view of the clamping-j aw shown in Fig. 2; and Fig. 7 is a perspective view of the aperture in the stationary jaw of Figs. 2, 4., and 5.
A is one of the longitudinal main frames of a tentering-machine, and is provided with a conveyer-guide 13,111 which the endless chain or conveyer 0 moves. The conveyor 0 is guided about guiding rolls or cylinders D D. The conveyor 0 is made up of links, all or a portion of which are provided with clamps E. In Figs. 9 and 10 only a few of these clamps are illustrated, though theymay be upon every link or every other link, as desired.
In all of the constructions of clamps illustrated the link is provided with a stationary jaw G, having a gripping-surface 9, combined with a pivoted frame H, hinged to the lower jaw at H and having hinged or journaled at its free end a movable jaw I, the lower end of which is adapted to grip the fabric resting upon the surface 9. In addition to these elements there is a locking device for positively lockingthe frame I-I relatively to the lower jaw, so that it cannot be thrown upward or away from said lower jaw when the gripping operation of the movable jaw comes into action.
Referring specifically to Figs. 1 and 2, we have the pivoted jaw I, provided at the rear with a controlling-finger J and a transverse locking-bar L, the said parts being clearly shown in Fig. 8, and adapted to a slot M N (see Fig. 7) in the face of the lower jaw G The frame H is provided with a heel extension h, which limits its downward movement. The upper part of the jaw I is provided with .an extension K, while the upper part of the frame His also provided with a projection R, the said parts being operated upon by suitable cams for controlling the movements of the parts H and I. The operation of this cam will now be understood. Assuming that the frame II and the jaw I are thrown backward, as indicated in Fig. 10, the cloth is drawn into the machine and allowed to rest directly upon the face 9 of the lower jaw. As the clamp rises the cam f operates upon the projection R and throws the frame H over into position indicated in Fig. 2, and this brings the controlling finger J and the locking-bar L upon the fabric, and thereby holds the jaw I from gripping the fabric. As the fabric is drawn from under the parts J and L it permits said parts to fall into the apertures M N, andthereby throws the gripping edge of the jaw I upon the extreme lateral edge of the fabric. As the locking-bar L falls through the grooved slot N it locks the frame H at substantially the same moment that the jaw I grips the fabric, as it is under the locking operation of the said jaw.
that the gripping operation takes place. After the tentering operation has been completed suitable cams first operate upon the part K to throw the locking-bar L out of the slot N and then act upon the projection R to raise the frame 11, so as to be in position for receiving the fabric upon its return to the startingplace. It will be observed that in this construction the lock for the frame II is combined with the controlling-finger J, and thereby forms a very inexpensive construction.
Referring to Fig. 4, we have the jaw I counterweighted, as at 2', and pivoted to the frame H independently of the controlling-finger. In this case the controlling-finger J is also provided with a transverse locking-bar L and is pivoted upon the end of the frame II independently of the movable jaw I. This controlling-finger is also provided with a counterweight j, and which operates upon the counterweight of the jaw I, whereby the raising of the controlling-finger will throw the jaw out of clamping action, and vice versa. The jaw I should be so counterweighted that it will fall of its own weight to grip the fabric, and this action may be insured by making the controlling-finger J positively strike the back of the jaw I and throw it downward. The controlling-finger J is also provided with a projection K, to be acted on by the cam in place of the projection K of the jaw shown in Fig. 2. The operation of the controllingfinger and locking-bar is precisely the same in this figure as in the construction shown in Fig. 2.
Referring to Fig. 5, we have substantially the construction of Fig. 4, and in this case the controlling-finger J 2 is connected with the pivoted jaw I by a tooth connection O,which sustains the jaw away from the fabric until the controlling-finger J 2 has been liberated. In this case the descent of the controlling finger J positively causes the jaw I to be pressed down upon the fabric. The locking action of the parts L N in this construction is the same as that of Figs. 2 and 4.
Referring to Fig. 3, we have the jaw I, provided with the controlling-finger J, as in Fig. 2; but there is no locking-bar L or transverse slot N. In lieu thereof I employ a pivoted lock P, arranged below the jaw G and adapted to be thrown into and out of position relative to the heel extension h of the frame If. The pivoted lock P is connected with the upper end of the jaw I by a light link p. It will now be understood that when the fabric is drawn from under the controlling-finger J so as to bring the gripping action of the jaw I into operation the movement of the jaw I draws down the pivoted lock P and thereby simultaneously locks the frame H at the moment the jaw I is gripping the fabric.
In the construction shown in Fig. 6 we have all of the elements the same as in Fig. 3, with the exception that the controlling-finger J is dispensed with and an upwardly-extending controlling-finger J attached to and moving with the lock P, is employed. In this case the fabric holds the lock P out of position as well as the jaw I away from the fabric until after the fabric is liberated by the free end of the controlling-finger J It will be observed that in all of these constructions, which are modifications of the same general invention, there is a frame movable relative to one of the jaws and carrying thereon the second or movable jaw, combined with a locking device for locking the movable frame relatively to the first-mentioned jaw to permit the gripping action of the second or movable jaw. It will be observed that in the preferred construction of my improvements there is a relation between the locking devices and the movable gripping-jaw which insures the locking and gripping action to take place simultaneously or about at the same instant, thereby obviating lost motion and simplifying in a great measure the devices.
VVhile I prefer the constructions herein described, I do not confine myself to the details thereof, as they may be modified without departing from the spirit of my invention.
Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is-
