CLIP FOR TENTERlNG-MACHINES.
Specification of Letters Patent.
Patented Aug. 21, 1906.
To all whom, it may concern:
Be it known that I, ALFRED AUSTIN l/VHIT- LEY, engineer, a subject of the King of Great Britain and Ireland, residing at East View, Higher Lane, Whitefield, Bury, in the county of Lancaster, England, have invented certain new and useful Improvements in Clips for Use in Tentering-Machines for Stretching or Finishing Textile Fabrics, of which the following is a specification.
This invention relates to clips employed in tentering-machines for stretching or finishing textile fabrics, in which clips the lever carrying the gage tongue or finger (which by bearing on the fabric causes the clip to be kept from engaging the fabric) is separate from, the upper jaw, between which upper jaw and the lower jaw or plate the fabric is gripped when by its passing from beneath the gage tongue or finger the said gage tongue or finger is released.
The object of this invention is to provide very efiiciently acting clips by which a perfect grip of the fabric is insured when it passes from beneath the gage tongue or finger and in which the pressure of the said gage tongue or finger upon the fabric is not too great' I will describe this invention with reference to the accompanying drawings, representing in perspective arran ements of clips made in accordance therewith.
Figure 1 shows one arrangement; Fi 2, a modification, and Fig. 3 a further modification.
Referring first to Figs. 1 and 2, the upper jaw 1 is carried and turns on a rod or spindle 2, mounted in the frame 3 of the clip, and the lever carrying the gage tongue or finger 4 is mounted and turns on the same rod or spindle 2, and on another rod or spindle 5 (also mounted in the frame 3 of the clip, one arm of the frame being shown broken away) is mounted a bell-crank lever 6 and an opening lever 7, which opening-lever when moved in one direction presses upward the arm 8 of the aforesaid bell-crank lever 6, (by the part 9 acting on the part 10,) so that when the said gage tongue or finger is raised to admit of the fabric passing beneath it the said arm 8 is raised into position to be engaged by an arm 11, forming with the gage tongue or finger 4 a bell-crank lever. The gage tongue or finger 4 is raised by a projection or spur 12 on the openinglever, (or it may be on one of the arms of the bell-crank lever,) which projection or spur 12 when the opening-lever 7 is moved. to open the clip presses on the afore said arm 11 of the lever of the gage tongue or finger 4, thereby causing the said lever and the gage tongue or finger 4 to turn on the rod or spindle 2, the upper jaw 1 of the clip being at the same time raised to admit of the fabric being passed beneath the said jaw l and beneath the gage tongue or finger 4. When the gage tongue or finger 4 is supported by the fabric, the arm 8 of the bell-crank lever 6 rests on the arm 11 of the lever of the gage tongue or finger 4, and the said gage tongue or finger 4 does not exert undue pressure on the fabric.
Projecting from the upper jaw 1 is an arm or lug 13, preferably provided with a roller 14, and on the arm 15 of the bell-crank lever 6 is a support 16, (which is shown as a simple recess in Fig. 1 and as a roller on a pin in Fig. 2,) which support 16 when the upper jaw 1 is raised engages with the arm or lug 13 on the said upper jaw (or the roller 14 thereon, if one be employed) and holds the said jaw 1 in its raised position.
When the fabric is drawn from beneath the gage tongue or finger 4 and the said gage tongue or finger descends through the opening or openings in the under jaw or plate 17 of the clip, the arm 11 of the lever of the gage tongue or finger 4 leaves the position in which it supports the bell-crank lever 6, which bell-crank lever will then turn on the rod or spindle 5 and remove the support 16, carried by the said lever, out of engagement with the arm or lug 13 (or the roller thereon, if one be used) on the upper jaw 1, which be ing thus released will descend onto the fabric. The opening-lever 7 then being free will be turned by the spring or springs 18, and a wedging-surface constituted by the camshaped part on the under side of the-spur 12 on the said lever 7 will be caused by the said spring or springs to bear on the arm or lug 13 (or the roller 14 thereon, if it be used) on the upper jaw 1 and press the said jaw firmly onto the fabric. The said spring or springs '18 is or are conveniently attached at one end to the frame of the clip and at the other end to an upwardly-projecting arm from the opening-lever. In Fig. 1. two springs are shown connected at one end to books 19, carried on the rod or spindle 2, and at the other end to hooked projections 20 from the opening-lever 7, and in Fig. 2 one spring is indicated as being connected to pins 19 and 20, carried by the frame 3 and the opening-lever 7, respectively.
In the modification shown in Fig. 3 the opening-lever is arranged to bear on the arm of the gage tongue or finger and is provided with the means to lift the upper jaw, and a separate lever carries the aforesaid wcdgingsurface and is acted upon by the aforesaid spring or springs. The parts which correspond with those shown in Figs. 1 and 2 are marked with the same reference-numerals The support 16 for the upper jaw 1 of the clip consists of a cam-surface formed on or constituting an extension 15 of the openinglever 7 and acting on the extension or arm 13 (preferably with the intervention of a roller 14.) on the upper jaw and either on the same spindle 5 as that carrying the openinglever 7 but preferably on a separate spindle, as shown at 21, is a wedging-piece 121, which in the position shown is kept off the extension 13 by the projecting part at 22 bearing on the cross pin or bar 23 on the opening-lever 7; but when the upper jaw 1 is bearing on the fabric the pin 23 is removed from the po sition shown and the wedging piece 121 presses upon the extension 13 (or its roller 14) on the upper jaw 1 and locks the said upper jaw on its engaging position, as in the arrangements Figs. 1 and 2. The pressure of the wedging-piece 121 is effected by a spring or by springs 18, attached at one end to hooks 20 on the upper end 24 of the wedgingpiece 121 and at the other end to the hooks 19. In all the arrangements the relative ar rangement of the parts is such that when the opening-lever 7 is moved in the direction to raise the upper jaw 1 the wedging-piece 121 is first moved out of contact with the extension 13 on the upper jaw (or the roller 14 on such extension) before the cam-surface 16 for raising the upper jaw comes into action on the said extension 13, (or roller 14.)
The upper jaw and the lower jaw or plate may be plain, or the upper jaw may be pro vided with pins for engaging the fabric, the lower j aw or plate then having openings in it to receive these pins.
Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I claim as my invention- 1. In clips for tentering-machines, the combination with the upper jaw and lower jaw or plate, of a gage tongue or finger, mounted on the same spindle as the upper jaw, a lever provided with means to effect the lifting of the upper jaw and the gage tongue or finger, an arm on the gage tongue or finger for the lifting-lever to rest upon when the said gage tongue or finger is on the fabric, and a wedging-piece caused to be operated by a spring means to wedge down the upper jaw onto the fabric when the said fabric passes from beneath the gage tongue or finger.
2. In clips for tentering-machines, 'a gage tongue or finger, separate from the upper jaw but mounted on the same spindle, an opening-lever provided with means to lift both the upper aw and the gage tongue or finger, the said 0pening-lever being arranged to be supported on an arm of the gage tongue or finger when the said gage tongue or finger rests on the fabric, and a wedging-piece operated by a spring means, whereby when the said arm is withdrawn from beneath the 0pening-lever the said wedging-piece is caused by the spring or springs to bear forcibly upon the upper jaw.
In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
ALFRED AUSTIN WHITLEY.
