(01. 66-86; This invention relates to knitting machines and more particularly to Galon machines for the knit ting of curtains, trimmings and the like. Machines of this type are old and well-known 5 and have been in use, substantially without change, for many decades. As is well-known by those skilled in this art, a machine of this type includes a main camshaft having a plurality of cams for operating the various moving portions 10 of the machine, to wit:—the needle bar, yam rod fork, and take-up rolls. The machine also in cludes certain other cams for operating the warp bar, the pattern chain advancing and reversing 5 mechanism, etc. Heretofore the machine per 15 formed one complete cycle of operation for each revolution of the drive shaft and of the main cam shaft, and, of course, the capacity of the machine Fig. 3 is a similar view of the pattern chain " advancing and reversing mechanism. _ Fig. 4 is a cross-sectional view to an enlarged scale as taken along the line 4-4 of Figure‘ 1. V Fig. 5 is a semi-diagrammatic front view of the machine showing the mechanism for alter nately moving the pattern chains. Fig. 6 is, a fragmentary detail of the ‘two to one‘ 10 drive between the drive shaft and one of the pattern chains. v ‘ ‘ The machine, in the usual manner, is provided with a. needle bar A, a warp bar B, a take-up roll C, yam'rods D, yarn rod forks E for elevat 15 ing and lowering the yarn rods, pattern chains F and G, and drive mechanism H for advancing consistent with good machine practice. ’ and reversing the pattern chains. 1 The machine is driven by means such as the “The present invention seeks to increase the capacity of a Galon machine without, however, pulley ID, or may be operated during adjust 20 ments by the handwheel I l, suitable clutch means increasing the speed of the drive shaft. or cam I! ‘being incorporated to permit this. was limited to the maximum vspeed obtainable 2O Fig. 2 is a‘ front view of the warp bar rocking mechanism. shaft. This broadly stated object of the invention ' By either of the above means, the shaft I3 is may be realized in several ways as will later be driven and on this shaft is mounted a‘ miter gear‘ more fully detailed.

I . In accordance‘ with the‘ invention, the three " shafts l3, l6 and i9 are provided with cams for ' 30 operating the various moving portions of the machine and in order to provide the machine with increased capacity at the normal rotational. speed of the mentioned shafts, all of the cams are ‘ formed as double lobed cams as will hereafter be 35 seen. ‘ with particular reference to Figures 1 and 4, the camshaft I6 is provided with one or more necessary to convert the machine from one meth- - - double lobed cams 20, each acting on a roller 2| ed to the other. 40 4 carried on an arm 22 ?xed to a common rock Another object of’the invention is tovprovide. shaft 23. The arms 22 are each connected at 2,4, a pattern chain at each end of the machine which, to a drag link 25 pivotally connected at 26' to the for any particular design of knitted fabric, is' needle bar A. From the foregoing it is apparent considerably smaller than has heretofore been that each revolution of the camshaft IE will cause used, that is, the number of links comprising each - two movements of the néedle bar A towards" the chain' being less than previously required. The machine as at present contemplated, is fully described in the following detailedv speci ?cation as based on the accompanying draw 50 ings in which preferred embodiments thereof are illustrated.

The means for moving’ the‘ needle ‘bar to the > right in a similar manner comprises a double lobed cam 21 acting on a roller 28 on a bracket 29 ?xed to the needle bar, said bracket being 60 provided with‘an extension 30 which is guided as by means of the grooved wheels 3|. The means for elevating the yarn rod forks E twice for each revolution of the camshaft l6, ' comprises one or more double lobed cams I2, 55 2,163,852 each acting on a roller 33 carried on an arm 34 ?xed on a rockshaft 35, an arm 36 on each sized gear ‘I0 so each pattern chain is rocked once for ‘'‘one revolution of the main shafts end of the rockshaft being pivotally engaged - or for two actions of the double lobed cams with which the machine is equipped. with the yarn rod forks for this purpose. Hence, a machine equipped with double lobed The take-up roll C is advanced twice for each revolution of the camshaft by means compris ing the double lobed cam? 31 acting on the roller 38 on an arm 39 on the rockshaft 23, the, arm 39 cams and with means for causing the pattern chains to operate alternately will attain a degree of efficiency, at least twice that of machines in present use, being faster and being easier to set up due to vthe saving in the number of links being formed with a lower extension 40, the end 10 ll of which, through a link 42 is connected to a lever 43 pivotally engaged on the stud 44.

As can' be seen from the foregoing, the present retain the parts in advanced position during th recovery motion of the ‘pawl. ~ In the action of the machine, the warp bar 3 is both rocked and moved endwise, these move ments beingaccomplished twice for each revo ‘lution of the shafts l3 and i9. The rocking of the warp bar is attained 30 according to‘ this invention, improved to a con siderable degree. It is now possible to knit cer- , tain fabric designs by only employing one or two actuators on each end of the-machine, discon-_ necting, of course, the advancing means H.‘ Also, 30 it is ‘possible to knit quite complicated designs through the medium of a double lobed cam 50 on the shaft l9 acting on a roller 5| on a slide into fabrics with half the number of actuators member 52, guided in a bracket 53 and urged upwardly by means of a spring 54.

A spring 60 is employed to 45 maintain the roller against the cam at all times; When the pattern chains F and G are to be 35 of the drive shafts, may be provided with double lobed cams, the others then being geared to ro 40 tate at twice the speedand provided with single lobed cams. For this reason the scope of the following claims should not be based on the present speci?c disclosure, but rather on the prior art. ' vWhat is claimed as new and desired to secure .. rocked inwardly and outwardly simultaneously by Letters Patent, is: 1.- In a knitting machine having yarn rods, a in the usual manner of operation, the drive 1 means therefor is shown in Figure 6 wherein a '3 main shaft for actuating said machine, a pat 60 gear 8! is provided on the shafts l3 and I9, and ,‘is‘meshed with a half size gear 62 on a counter This countershaft is provided with a crank arm 64, which, through the medium of a link 65, is connected to a swinging .arm» 66 fulcrumed at 61. The arm 66, in'the usual man - shaft 63. ner, supports the two sprocket-like members ‘68 about which the. pattern chain istrained. In the foregoing manner the pattern chains .

In a knitting machine, a drive shaft, knit 60 ting instrumentalities, means for actuating said knitting instrumentalities twice for each revolu tion of the drive shaft, a pattern chain at. each end of the machine, and means actuated from While this method of equipping a Galon knit ting machine considerably increases the capacity said drive shaft for vsimultaneously moving one 65 thereof, "for certain types of designs of ' knitted pattern chain towards and the other - pattern fabrics, the machine may be made more e?icient chain away from the machine to move a yarn rod in‘that the pattern chains may be made smaller,“ in one direction before one actuation of the knit ting instrumentalities and for simultaneously comprisingrless links. .
