PATTERN MECHANISM- FOR LOOIVIS;
Specification of Letters Patent.
Patented May 31, 1910.
Application filed February 4, 1910. Serial No. 541,972.
To all whom it may concern:
Be it known that I, JOSEPH T. CYR, a citizen of the United States, residing at IVorcester, in the county of W'orcester and State of Massachusetts, have invented certain new and useful Improvements in Pattern Mechanism for Looms, of which the following is a specification.
My invent-ion relates to pattern mechanism for looms, and more particularly to pattern chains, made up of bars connected by links, and carrying rolls and tubes thereon, forming the pattern surfaces or indicators. The ends of the bars, ordinarily with tubes thereon, fit into notches or recesses in the heads of the pattern cylinder. The revolution of the pattern cylinder, through the engagement of the ends of the bars with the notches or recesses in the cylinder heads, causes the movement or rotation of the pattern chain.
In pattern chains of the class referred to, and particularly in case of short chains, the chains will sometimes become disarranged on the pattern cylinder, or entangled by winding on the cylinder, by reason of the ends of the pattern chain bars getting caught in, or not properly passing out of the notches or recesses in the pattern cylinder heads.
The object of my invention is to provide a supplemental attachment or device, adapted to be combined with a box pattern chain, or harness pattern chain of the class referred to, and particularly with the ends of the pattern barrels or cylinders, to extend into the path of, and be engaged by the links of the pattern chain, which connect the bars carrying the tubes and rolls, and act to raise the ends of the bars out of the notches or recesses in the pattern cylinder heads, and cause the chain to remain in its proper position on the pattern cylinder.
My supplemental attachment or device for pattern chains, which I term a pattern chain stripper, is preferably loosely mounted on the pattern cylinder shaft or barrel, and is held from turning around on the pattern cylinder shaft or barrel with the pattern cylinder.
My invention consists in certain novel features of construction of my improvements as will be hereinafter fully described.
I have only shown in the drawings a detached portion of the well known Knowles head motion for looms, shown and described in Reissue Letters Patent, No. 7,784, showingv the box. and harness pattern chain cylinders and chains, with my improvements applied thereto.
Referring to the drawings :Figure 1 is a sectional elevation through the Knowles head motion, and the harness pattern chain cylinder, taken at a point indicated by line 1, 1, Fig. 2, looking in the direction of arrow at, same figure. Fig. 2 shows, on an enlarged scale, the boX and harness pattern chain cylinders, and chains, detached, and as a section, on line 2, 2, Fig. 1, looking in the direction of arrow 6, same figure, and, Fig. 3 is an end view of the boX and harness pattern chain cylinders, and chains, and a section, on line 3, 3, Fig. 2,v looking in the direction of arrow 0, same figure.
In the accompanying drawings, 1 is the loom arch, 2 the stand secured thereto for supporting the several parts of the Knowles head motion, above referred to.
The head motion comprises the upper cylinder gear 3, fast on the cylinder gear shaft 4, the lower cylinder gear 5, fast on the lower cylinder gear shaft 6, the vibrator gears 7 intermediate the cylinder gears 3 and 5, the vibrator levers 8, which are pivotally mounted at their outer ends on the transverse rod 9, and carry the vibrator gears 7 on their inner ends, in. the usual way.
The vibrator levers 8 are raised and lowered by the harness pattern chain 10, which is supported on the rotary pattern chain cylinder 11, having heads or ends 11, with notches or recesses 11 therein, and made up of rolls 10, and tubes 10", mounted on bars 10', connected by links l0 in the usual way. The ends of the bars 10",
having in this instance the tubes 10 there-- on, fit into the notches or recesses 11" in the heads 11 on the pattern cylinder 11, and the revolution of the pattern cylinder 11, causes the revolution of the pattern chain 10. A chain support or guide 12, suitably secured on the loom arch 1, is adapted to support the chain 10.
The boX patternchain 13 is made up of rolls 13 and tubes 13", mounted on bars 13', connected by links 13 in the usual way.
he box pattern chain 13 is mounted on the rotary pattern cylinder 14, having heads 14 with notches or recesses 14 therein, for
the ends of the bars 13", which in this instance have tubes 13 thereon,
The pattern chain cylinders 11 and 14, are in this instance made in one piece or barrel, with reduced outer ends forming journals, see Fig. 2.
All of the above mentioned parts may be r of the usual and well known construction in the class of looms referred to.
I will now describe my improvements. I provide each pattern chain cylinder 11, and 14, at its outer end, with a device termed a chain stripper, which in this instance consists of a block 15, which loosely engages the end of the chain cylinder barrel or shaft, and is held thereon by a cap 16, see Fig. 3, which is made curved at one end to partially encircle the end of the chain cylinder, and secured at its other end by a screw 17 to the block 15. The block 15 has in this instance an engaging surface 15, over which the links of the pattern chain pass. A boss 15 on each guide device 15 is adapted to receive one end of a transverse rod 18, which connects the two chain strippers 15 together. A screw 19 secures the ends of the rod 18 in the bosses 15".
In connection with the two chain strippers 15, at the outer ends of the box, and harness pattern chain cylinders, I use a chain stripper for the inner ends of the box, and harness pattern chain cylinders, which consists in this instance of a boss 20 secured on the rod 18 by a screw 18, and two upwardly extending arms 20 having yokeshaped ends, which loosely engage the pattern barrel, between the inner heads of the pattern cylinders 10 and 13, as shown by broken lines in Fig. 1, and a third arm 20", which is offset and extends downwardly from the hub 20, and has the weighted end 20 thereon, which extends within the pattern chain 10 of the harness section, as shown, and rests on the inner part of the pattern chain, and acts to hold the blocks 15 and arms 20 in position, and prevent their rotating with the pattern chains. The arms 20 of the center chain stripper extend in the path of the inner links 10 and 13 of the pattern chains 10, and 13, and as said chains rotate, the passing of said links over said arms, causes the stripping or removal of the inner ends of the bars 10", and 13 from the notches or recesses in the cylinder heads on the inner ends of the pattern cylinders. passing of the outer links 10 and 13 of the chains 10, and 13, over the blocks 15, causes the stripping or removal of the outer ends of the bars 10 and 13 from the notches or recesses in the cylinder heads on the outer ends of the pattern cylinders.
It will be understood that the details of construction of my improvements may be varied if desired.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:
1. In pattern mechanism for looms of the class described, the combination with a pattern cylinder, and a pattern chain, of a plurality of chain strippers, having portions to loosely engage the pattern cylinder barrel or shaft, a rod or device to connect said strippers, and an arm on one of said strippers within the fold of the pattern chain, to prevent the revolution of said strippers.
2. In pattern mechanism for looms of the class described, the combination with a pattern cylinder, of a device to prevent the winding of the pat-tern chain on the pattern cylinder, said device having parts to loosely embrace portions of the pattern cylinder, and means to prevent the rotation of said device with the cylinder.
3. In pattern mechanism for looms of the class described, the combination wit-h a pattern cylinder, of a device to prevent the winding of the pattern chain on the pattern cylinder, said device having parts to loosely embrace portions of the pattern cylinder, and means to prevent the rotation of said device with the cylinder, said means comprising a weighted arm extending within the fold of the pattern chain.
