Description

April 1950 J. WAWZO-NEK 2,503,785
DIAL COUPLING Filed Aug. 18, 1948 Patented Apr. 11, 1950 UNITED STATE FATENT FICE DIAL COUPLING Application August 18, 1948, Serial No. 44,971
2 Claims.
This invention relates to the means by which the dial of a circular independent needle knitting machine is driven and, in particular, to a disconnectible coupling in such a drive.
In certain types of knitting machines the dial can be swung upwardly from its knitting position to an inoperative position without disconnecting it from its drive so that the timing of the dial is not disturbed. However, the swinging oithe dial in this way may so affect the operating connections to the dial cams that those which project the needles or bitts with which the dial is equipped may project them if the machine is operated and may leave them projected when the dial is brought down to knitting position.
Also no machine in use today permits of operation with the dial in knitting position without turning the dial also. It is advantageous to be able to operate the machine without turning the dial when the dial is in any position. This is made possible by this invention, one form of which is shown in the drawing of which:
Fig. 1 is a front elevation of the coupling in dial driving position;
Fig. 2 is a similar view showing the coupling released from the dial driving head;
Fig. 3 is a plan view of the coupling showing primarily the latch by which it is held in dial operating position and;
Fig. 4 is a similar view showing the latch withdrawn and the coupling released.
The dial may be driven from any suitable source through connections to a driving head 2. This head is provided with spaced projecting lugs 3 and 4 between which a downwardly projecting finger 5 of a cap 6 is capable of passing. Cap 6 is slidable on dial shaft 1, but is keyed thereto at all times by a key 8. Cap 6 is urged upwardly by a spring 9, the lower end of which rests upon the housing l0.
Shaft 1 is provided with an annular channel 5 l engageable by a latch l2 mounted upon cap 6. When latch I2 is in engagement with channel I I, the cap 6 is held down with its finger 5 between lugs 3 and 4 as shown in Fig. 1. Consequently, if driving head 2 is turned, mechanically or manually, the dial is driven and if the drive is of the non-disconnectible type, such, for example, as that shown in the pending application for U. S.
2 Letters Patent #38344, filed July 15, 1948, it will be driven regardless of its position.
On the other hand, ii latch 12 is released, cap 6 will be raised by spring 9 so that finger 5 is withdrawn from between lugs 3 and 4 as shown in Fig. 2. Then cap 6 and the dial I to which it is operatively connected will remain idle even though driving head 2 continues to rotate and regardless of the position of the dial. Consequently, the dial can be made inoperative in its knitting or any idle position and may be returned into operation in any of those positions merely by pushing down cap 6 until latch l2 automatically engages channel H. The form of latch shown at 12 is compact and convenient, but not essential. Its nature is obvious from the drawing and will not be described.
I claim:
1. A dial assembly for a circular, independent needle, knitting machine comprising a dial, a shaft secured thereto, a driving collar rotatable about said shaft, and a driving cap keyed to said shaft and slidable there along into and out of operative connection with said driving collar.
2. A dial assembly for a circular, independent needle, knitting machine comprising a dial, a shaft secured thereto, a rotatable driving collar, a driving cap keyed to said shaft and slid-able there along into and out of operative connection with said driving collar, resilient means operative to urge said cap away from said collar and a latch for holding said cap in operative connection with said collar.
