UNITED STATES P TENT; OFFICE-f- ROBERT E. LAWSON, 0F PAWTUCKET, AND AUGTJ'STIN GAGNE, OF CENTRAL FALLS,

RHODE ISLAND, ASSIGNORS TO HEMPHILL COMPANY, OF CENTRAL FALLS, RHODE ISLAND, A CORPORATION OF MASSACHUSETTS KNITTING MACHINE OPERATING MECHANISM- Application filed January 8,

This invention relates to knitting machine operating 7 mechanism.

In order that the principle of the invention may be readily understood, we have disclosed one embodiment of means for practising the same in the accompanying drawings, where- Fig. 1 is a rear elevation of a portion of the operating mechanism of a circular knitting machine; a

Fig. 2 is a side elevation viewed from the right of Fig.1 with one of the side frames of the machine removed Fig. 8 is a vertical section on the line 33 of Fig. 2'; and a Fig. 4 is a plan view of the mechanism shown in the other figures.

While this invention is not restricted to circular knitting machines of the Banner type, it is particularly applicable thereto in that it involves novel means for supporting and operating the so-called 104 gear of the Banner machine of the general type shown in the patent to Joshua D. Hemphill, No. 933,443, and many subsequent patents.

Heretofore the 104 gear has been mounted upon a stud extending through one of the frames only of the machine, and it has been impossible with the prior construction, to support the same upon a shaft with two bearings because the 104 gear has heretofore been provided upon one face with a pin to which a connecting rod is suitably connected. The proper movements of such connecting rod would have been impossible if a shaft had been provided for the 104 gear. According 'to the present invention the said pin and connecting rod are replaced by an eccentric and its connecting rod, as hereinafter disclosed, and the 104 gear is mounted upon a horizontal shaft supported in two uprights of the framing. Attention is called to the patent to Lawson & Lawson, No. 1,702,608, dated February 19, 1929, wherein the gear 7 is identified as the 104 gear. This gear is a characteristic element of the Banner knitting machine, and the present invention is directed to improved means for supporting and operating the same.

Referring more particularly to the drawsource.

1929. Serial No. 351.093.

ings, we'have, in Figs. 1, 3 and 4, represented the two uprights ofthe framing at 1, 2, and we have therein provided openings 3 and 4 in connection with which we provide suitable bearings indicated generally at 5and6; Said bearings themselves may be of any suitable character or type, and it is unnecessary to describe the same in detail.

; The bearing shown at 5 is or may be the I 7 gear is received isindicated' at 7, andthe-104 gear itself is indicated at 8. The said shaft is :novel in thisorganization, and is represented as broken away at its two ends, which ends, oreither of them, may receive cams'or U therefor. A suitable cover 12 is also provided.

In Figs. 1,=3land;4, the usual clutch member 13 is provided adapted to mesh as usual with the clutch members 14 and 15 which need not be fully described further than to state that the clutch member 15 has integral or formed therewith the pinion 16 which is reciprocated by the quadrant 17 Thesaid stud 21 having thereon a collar '22, as indicated clearly in Fig. 3. The clutch member 14 has fast therewith the pinion 23 by which the 104 gear is itself driven from the usual By the foregoing construction the 104 gear is more satisfactorily supported and without strain than in the former construcstood that although specific-terms are employed, they are used in a generic and descriptive sense and not for purposes of limitation, the scope of the invention being set forth in 5 the following claims.

We'claim: I 1. In a circular knitting machine of the socalled Banner type, the 104 gear, a shaft for supporting thesame, spaced upright members of the framing at opposite sides of said 104 gear, bearings for said shaft mounted in the said members of the framing of the ma- 1 chine, an eccentric fast with said 104 gear vbetween said framing members, a connecting rod for said eccentric, the quadrant and pivot- I al operatingvconnections between said connectingrod and said quadrant.

0 2.111 a circular knitting machine of the socalled Banner type, the 104 gear, a shaft for supporting the same, spaced upright mem bers of the framing at opposite sides of said 104gear, two bearings for said shaft supported upon the said members of the framing of' the machine, an eccentric, between said framing members upon said 104 gear and surroundingsaidl shaft, a connecting rod extending from said eccentric, the quadrant for reciprocating the needle cylinder or reciprocable element, and pivotal operating connece tions between said connecting rod and said quadrant. I 3. A circular knitting machine'of the socalled Banner type'having a quadrant, ashaft 1 e V whereon the same is mounted, a connecting rod pivotally connected to said quadrant, the

104 gear, an eccentric fast with said 104 7 gear and adaptedto operate said connecting rod, a shaft supporting said 104 gear, two bearings for said shaft at opposite sides re- 40 spectively of said 104 gear, and two spaced upright members of the framing to which said bearings are respectively secured.

In testimony whereof, we have signed our names to this specification.
