Patented Oct. 12, 1948 THREAD GUIDE BAR MOUNTING FOR, KNITTING MACHINES George Ostrom Young, Robesonia, Pa., assignor to Vanity Fair Mills, 1110., Reading, Pa., a corporation of Pennsylvania Original application October 15, 1945, Serial No.

2 Claims. 1

My invention, which relates generally to knitting machines, has for its object to provide a thread guide mounting of such construction that the guides may be swung to different angular positions and held there when adjustments, or replacements of guides becomes necessary, by virtue of which when more than one thread guide set is used on the machine, the front set may be swung out of the Way to give easy access to the other set, all without disconnecting the thread guide bars from the machine.

Other objects will in part be obvious and in part will be pointed out hereinafter.

To the attainment of the aforesaid objects and ends, invention further resides in the novel details of construction, combinations and arrangement of parts all of which will first be described in detail and then be specifically pointed out in the appended claims, reference being had to the accompanying drawing in which--- Fig. 1 is a front elevation of a portion of a knitting machine embodying my invention.

Fig.2 is a detail cross section on the line 22 of Fig. 1.

Fig. 3 is a detail perspective view of one threadguide-bar carrying arm and a portion of the thread guide bar.

In the drawing in which like parts bear the same reference numbers in all figures, the numbers used are the same as those used for the same parts shown in the drawings of my application, Serial Number 622,321, filed October 15, 1945, of which this application is a division.

The frame of the knitting machine is indicated by I6, the rod which carries resilient thread tensioning plates 15 (forming no part of the present invention) is numbered I3, while 66 is a fixed rod or shaft that has collars 68 (in the preferred construction) having splines 69 to fit grooves in the thread-guide-bar-carrying arms 10.

At least two of such arms III are provided and to them is secured a guide bar I21. The thread guides I24 are mounted on the bar IZI in the usual way.

The splines 69 do not extend the entire length of the collars 68 but extend far enough to permit racking to take place without sliding the arms I 011 the splines onto the unsplined portions of the collars 68. Racking is efiected by the action of the usual pattern, wheel I09, mounted at II", on the roller I 49 on the end of the slide rod I48 which is attached to one end of the guide bar I2I and a spring I 5i, which is anchored to the frame I6 and to a bracket I56 on another rod I48 that is attached to the other end of the guide bar IZI.

Thread from the beam (whose shaft 8| is mounted in saddles 82) passes over plate I5 to the thread guides I24.

When it is desired to swing a guide bar and its guide about the axis of the shaft 66 and hold them out of the way, the bar IZI may be uncoupled from the rods I48 and moved off the spline onto the smooth part of the collar after which the guide may be swung up around the axis of the shaft 66 to the desired position and then shoved back onto the splines to hold it there.

From the foregoing description taken in connection with the accompanying drawing it is thought the construction, operation and advantages of my invention will be clear to those skilled in the art.

What I claim is:

1. In a knitting machine the improvement which includes: a stationary shaft; at least two arms swivelly mounted on said shaft; a thread guide bar carried by said arms; thread guides on said thread guide bar; means holding said arms against swivelling; and means by virtue of which said thread guides may be racked, said first mentioned means including splines on said stationary 'shaft and spline grooves in said arms.

2. In a knitting machine the improvement which includes: a stationary shaft, collars mounted on said shaft, said collars each having a smooth portion and a splined portion adjacent thereto, arms mounted to slide on said collars and having spline grooves to receive said splines, a thread guide bar carried by said arms, and means for reciprocating said guide bar and arms Within the limits of said splines for racking purposes, said arms when moved beyond the limits of said splines onto the smooth parts of said collars being capable of being turned around the axis of said collars to change the position of said guide bar.
