FULL-FASHIONING HOSIERY MACHINE.
Application led December 30, 1926. Serial No. 157,954.
'lhis invention relates to full fashioning hosiery knitting machines of the Cotton frame type and particularly to the catch bar for operating the dividers and sinkers of such machines.
The invention is shown in the accompanying drawing in which Figure l is a4 sectional view of the improved catch bar and Fig. 2 is a plan View showing two sections of the catch bar, each section being adapted to cooperate with one section or head of the machine.
Fig. 3 is a view of a sinker.
Fig. 3a is a plan view of a siliker.
Fig. 3 is a rear view.
Fig.` 4 is a view of a divider.
As is well known to those skilled in this art, the Cotton frame is made up of a series of heads or sections arranged in a straight row, each section or head having a vertically reciprocating straight row of needles operated as a set with which horizontally movable sinkers a and dividers b cooperate.
These dividers and also the sinkers are operated by a catch bar. bar extends from end to end of the machine in one piece. As such machines are say forty feet long irregularities in the bar are liable to develop which .affects the accuracy of the knitting. Furthermore, if a divider or sinker needs renewal or repair it is necessary to pryy up the catch barfor the purpose of getting access to the row of dividers and sinkers.,
With my improvement I employ a catch bar in sections, each section serving oneof the heads or sections of the machine.
The sections indicated at l are mounted on a foundation bar 2 which latter extends from end to end of the machine. The catch bar section 1 is attached to the main bar 2 by bolts 3 passing through enlarged openings or slots indicated in dotted lines at 4 in the sections 1 and seated in the main bar.
There is one of thesev bolts at or near each end of each of the sections of the catch bar and by loosening these bolts the section of the catch bar can be adjusted to take care of any irregularity at any of the heads, or said sections can be removed so that access to the sinkers and dividers can be attained for their renewal or repair. The catch bar section is provided with the groove 4x which receives the upstanding butts of the sinkers Ordinarily this and dividers. If Athe main bar 2 is out of true from end to end the irregularity can be compensated for by loosening the bolts 3 and shifting the catch barsection 1 on the main bar 2 to cure the irregularity.
The catch bar is operated in the usual wa That is to say the main bar is provi ed with arms attached thereto one of which is shown at 5 and these arms have `each a lever 6 pivotally connected thereto whichlever is pivotally mounted at 7 to a suitable part ot the frame. The levers are operated in the ordinaryway to give the catch bar its forward and backward movement. The catch bar is moved up 'and down in the ordinary way by a rod or rods 8.
The upward and downward movement of the catch bar effects disengagement from and engagement with the butts of the sinkers, as in ordinary practice. Also as in ordinary practice the catch bar maintains its engagement at all times with the butts d of the dividers b which butts are longer vertically than the butts c of the sinkers. The
sinkers are operated forwardly to sink the.
yarn to the row of needles in the usual manner by jacks 9 and a slur cock indicated at 10. This forward movement of the sinkers takes place while the catch bar is elevated and disengaged from the butts of the sinkers. After the yarn has been sunk to the alternate pairs of needles progressively alongthe needle row by the sinkers operated progressively by the slur cock and jacks, the catch bar advances by the operation of the levers 6 to advance all the dividers simultaneously. This completes the sinking of the yarn to all the needles, the action of the dividers being to divide the yarn previously sunk between alternate pairs of needles and feed one half of this to the other needles so'that each needle throughout the row will have its quota of yarn sunk thereto. p
The back motion of the jack sinkers and the backward and forward lnovements of the dividing sinkers are accomplished by the catch bar.
All the above actions are old and well known. The improvement disclosed herein relates to the catch bar which though made in sections, one for each head, and though performing all the actions necessary to lcarry out the prescribed operations, yet is made up of a series of catch bar sections or units individual to the numerous heads of which the machine ma be composed, each section being capableofy adjustment individually to compensate for irregularities in the catch bar considered as a whole, and each section being removable and replaceable, to allow access to the si'nkers and dividers of the particular head served bythe section without disturbing or distorting the main bar 2, or disturbing the rela-tion of the catch bars of adjacent sections.
The butt of the sinker is reinforced by pieces e of right angular form secured to its sides by rivets. These reinforcements consist of thin metal pieces extending ver tically at each side of the butt of the sinker with horizontal extensions along opposite sides of the main body of the sinker. The sinkers are made, very thin and the reinforcement adds to the life of the sinker and presents a thickened rear edge against which the jacks bear and may Work with certainty and without undue wear.
I claim: l
1. A catch bar for knitting machines of the Cotton frame type employing sinkers and dividers, said catch bar being in sections, one for each head on the machine, a foundation bar to which the catch bar sections are removably attached and means for operatin the catch bar, said means being connected with the main foundation member 4 of said catch bar, substantially as described.
2. A catch bar for 4knitting machines of the Cotton frame-type employing sinkers and dividers, said-catch bar being in -sections, one for each head on the machine, a foundation bar, means for attaching each catch bar section to the foundation bar for individual adjustment, and means connected to said foundation bar to opera-te the catch bar organization as a whole, substantially as described.
.ment to allow access to the sinkers and di- 3. A catch bar for knitting machines of the Cotton frame type employing sinkers nected to said foundation bar to operate the catch bar organization as a Whole,.substan tially as described. p
4. A catch bar for knitting machines of the Cotton frame type employing sinkers and dividers, said catch bar being in sections, one for each head on the machine, a foundation bar to which the catch bar sections are movably attached, and means for operating the bars, substantially as de-v scribed.
5. A catch bar for knitting machines of the Cotton frame type employing sinkers and dividers, said catch bar being in sections, one for each head on the machine, a foundation bar, means for attaching each catch bar section to the foundation bar for individual adjustment, and means to operate the catch bar organization as a whole, substantially as described.
6. A catch bar for knitting machines of the Cotton frame type employing sinkers and dividers, said catch bar being 1n sections, one for each head on the machine, a foundation bar, means for attaching each section to the foundation bar for its individual adjustment thereon or its individual displaceviders at said section, and means'tooperate the catch bar organization as a Whole, substantially as described.
In testimony whereof, I'afx my signature.
