Int. Cl. D04b .15/ 76 U.S. Cl. 66-50 4 Claims ABSTRACT F THE DISCLGSURE An angularly adjustable eccentric stud mounting on a latch needle circular knitting machine for and upon which a needle-driven inclined rotary design wheel is journalled and wherein changes in the angular position of the stud causes the design Wheel to be adjusted lengthwise of its plane of inclination to thereby adjust the level to which selected needles are raised by the design wheel.

The present invention relates generally to the art of knitting and more particularly to needle-driven inclined rotary design wheels of the type used on circular latch needle knitting machines for selective needle raising, the invention providing a novel mounting for individual ones of the said Wheels whereby the position of the latter may be readily adjustably moved to accordingly vary the level to which selected needles are raised by the said wheels.

lIt is an object of the present invention to provide means whereby the position of individual ones of the aforesaid design wheels may be readily adjustably moved lengthwise of the planes of their inclination with the result that the level to which selected needles are raised will be varied accordingly.

It is a further object of the present invention to provide an angularly adjustable eccentric stud mounting for and upon which individual ones of the aforesaid design wheels may be rotatably journalled and wherein angular adjustment of the said stud will result in a corresponding change in the position of its associated design wheel.

The above and other objects and advantages of the invention will be fully apparent hereinafter, it being understood that the present invention is primarily concerned with a novel mounting to provide for the adjustable positioning of inclined design wheels and the combination therewith, all as will be described in detail hereinafter, as shown in the accompanying drawings which are illustrative of certain preferred embodiments of the stud mounting and as set forth in the appended claims.

In the drawings:

FIG. 1 is an outer elevational view, partly in section, of a portion of a cylinder cam section of a latch needle circular knitting machine of the type using a needle-driven inclined rotary design wheel and showing the novel angularly adjustable stud mounting of the present invention in position thereon and upon which the inclined design wheel is rotatably journalled, the said stud and wheel being shown in one of their adjusted positions relative to the stud supporting fork of the cam section and to the cam section itself.

Patented Nov. 24, 1970 ice FIG. 6 is a plan View of FIG. 5.

FIG. 7 is a plan view similar to FIG. 6 showing a modified form of the present invention, and

FIG. 8 is a plan view also similar to FIG. 6 showing another modied form of the present invention. In certain latch needle circular knitting machines it 1s customary to provide for needle selection at the feeds thereof by the use of needle-driven inclined rotary design wheels to raise selected needles from one level to one or more other levels, the wheels being driven by progressive engagement with the butts of the needles of the machine. Each inclined design wheel is rotatably joumalled upon the shank of a stud positioned perpendicularly to the angle of its inclination, the stud projecting upwardly from a fork shaped base extending radially outwardly from the circular cam section of the machine. The Wheel and its stud are adjustable radially of the machine along the fork shaped base to move the Wheel toward and away from the needle cylinder of the machine and the needles contained therein.

The present invention provides for an additional adjustment of the inclined design wheels in directions extending transversely of the radial adjustment above set forth and in such new adjustment the wheels are moved lengthwise of their planes of inclination. The result of such adjustment is to vary the level to which the needles are raised by the design wheels. The adjustment is accomplished in the present instance by the use of specially fonmed studs the Shanks of which are eccentrically disposed relative to their heads, however, it will be understood that the invention is not limited thereto.

ln the drawings, FIGS. 1 and 2, a portion of a circular cam section of a latch needle circular knitting machine is shown at 10, of which an upper face is inclined as shown at 11. Set in a radially extending milled slot in the face 11 and flush therewith is a radially extending open ended fork shaped member 12, the latter being retained in position in the cam section by means of a countersunk head screw 13 extending through a suitable Aaperture in the base of the fork 12 and into threaded engagement with the cam section 10. The fork 12 is provided with a pair of spaced

parallel arms

14, 14 each of which is undercut at 15, 15 along their length, the fork being adapted to slidably receive and to adjustably support the stud of the present invention between the arms thereof.

The stud, shown at 16, is provided with a square shaped head 17, a short circular shank portion 18 extending from and centered in the head 17 and a further circular threaded shank portion 19 in extension of and of larger diameter than the shank 18, the shank 19 being eccentrically disposed relative to the shank 1'8 and to the center of the head 17, the Shanks 1S and 19 *being tangent to a common plane parallel to one side 17a of the head. The center line of the head 17 and of the shank 18 is shown at 18a while the center line of the shank 19 is shown at 19a.

The shank 18 is received between the non-undercut portions of the

arms

14, 14 of the fork 12 and its length is such as to permit the said arms to be slidably received between the head 17 and the shank 19 of the stud 16. The head 17 is of a size to fit between and to be lengthwise movable along the undercut portions 15, 15 of the

arms

14, 14 of the fork 12. A shouldered bushing 20 is placed over the projecting sha-nk 19 and a design wheel 21, part of which is shown in section in FIGS. l and 2, is placed over the bushing, the wheel being retained in place by a washer 22 placed over the shank 19 in contact with the bushing 20 and by a nut 23 in threaded engagement with the shank 19. It will be obvious that this arrangement permits radial adjustment of the wheel 21 relative to the cam ring 10 and to the needles in the needle cylinder of the machine.

As shown in FIG. l, the wheel 21 is in its uppermost position of adjustment lengthwise of the inclined surface 11 relative to the cam section 10 and associated parts, including the needle operating cams (not shown), the stud 16 being disposed with the side 17C of its head 17 visible from the open end of the fork 12, the center line 19a of the shank 19 being above the center line -18a of the shank 18 and of the head 17. In order to place the wheel 21 in its lowermost position of adjustment lengthwise of the inclined surface 11, the stud 16 is caused to be turned one hundred and eighty degrees from its position in FIG. l to its fposition in FIG. 3 wherein the head 17 is now disposed so that its side 17d is visible from the open end of the fork and wherein the center line 18a is above the center line 19a. Similarly, in order to place the wheel 21 in an intermediate position of adjustment, the stud 16 is caused to be turned ninety degrees from either its position in FIG. 1 or in FIG. 3 to its position in FIG. 4 wherein the head 17 is now disposed so that its sides 17C and 17d are parallel to the

arms

14, 14 of the fork 12 and wherein either its side 17a (shown) or its side 17b (not shown) will be visible from the open end of the fork, the

center lines

18a and 19a coinciding when the parts are viewed as in FIG. 4.

It will be understood that the stud 16 and the parts thereon are withdrawn (after rst loosening the nut 23) from the fork 12 in order to change the angular position of the stud after which the stud is reinserted into the fork 12 and the nut 23 is made tight thereon (against washer 22 and bushing 20) to hold` the parts in adjusted position. It will also be understood that during such angular adjustment of the stud and wheel, radial adjustment of the stud and wheel can also be made at the same time, as may be required, in coordination with the said angular adjustment of the stud and the wheel. In

other words, as the Wheel is adjusted up and down to vary the level to which needles are raised thereby, it may also be adjusted radially as required in order to maintain the proper relation of the needle butts therewith. The adjustments provided by the present invention are relatively small and permit the needles to continue to be taken by the adjusted wheel at their normal level of approach to the latter.

A modification of the stud 16 is shown in FIG. 7, this modification providing the head thereof with an additional pair of spaced

parallel sides

17e and 17f which are formed by cutting off equal triangular portions from diagonally opposite corners of the head, the distance between the faces 17e and 17j being equal to the length of one side of the pre-cut head 17. With this modi- 4lication, the stud 16 may be disposed in the fork 12 with one and with the other of the uncut corners of its head visible from the open end of the fork to provide an additional pair of adjustable positions for the wheel 21.

A further modification of the stud 16 is shown in FIG. 8 by means of which two adjusted positions of the wheel may be obtained. Instead of the stud being formed with a shank 18, it is formed with-its olf center shank 19 extending directly from the head 17 (without a shank 18) with the shank 19 undercut, as at 24, along one side thereof adjacent to the head 17 and parallel to side 17a, the so undercut portion of the shank being received between the

arms

14, 14 of the fork 12 with the side 17c or the side 17d of the head visible from the open end of the fork to provide two adjusted positions for the wheel 21, these corresponding to the positions thereof shown in FIGS. 1 and 3.

It will be understood that other means may ibe used to propide an adjustable mounting for the design wheel, for example, the shank of the stud may be made concentric with the center of its head and the bushing may be formed with an eccentric aperture to t on the shank of the stud whereby angular positioning of the bushing will provide for the adjustment of the design wheel.
