LOOPlNG ATTACHMENT FOR KNITTING-MACHINES.
SPECIFICATION forming part of Letters Patent No. 537,748, dated April 16, 1 895.
Applicati n filed August 9, 1894- Serial No. 519,826. (No model.)
To aZZ whom it may concern..-
Be it known that I, ARTHUR BROWN, of Detroit, in the county of Wayne and State of Michigan, have invented a new and useful Improvement in Looping Attachments for Knitting-Machines, of which the following is a specification.
My invention consists in an improvement in looping attachments for knitting machines, hereinafter fully described and claimed.
Figure 1 is a side elevation partly in oentral section. Fig. 2 is a top plan view of one half of the machine. Fig. 3 is a sectional illustration, forthe purpose of showing the double yarn guide. Fig. 4 is a detail showing the formation of the loops and stitches, and Fig. 5 is a section illustrating the throwing of the loops. I
A represents a rotary needle cylinder and B represents a stationary cam cylinder. Oylinder A is rotated by any suitable means.
0 represents needles carried in the needle cylinder A, and operated by the cam cylinder, all of which is old and well known.
D represents a ring, supported from a stationary cam cylinder B, in which fits and slides the ring E, carrying a series of points F, which project inwardly between the needles 0, preferably extending in just as far as the inner side of the needles, and the ring E with its points F, rotates in unison with the needle cylinderA through the pressure of the needles againstsaid points F.
G represents a yarn guide which is carried on a bracket I above points F, and provided with a hole g to feed the yarn, and another hole 11 to feed another yarn is formed through bracket I below said points, and said lower yarn may also pass through a hole h in the supplemental yarn guide H secured on the under side of the ring D.
- 7' represents an ordinary yarn guide.
The operation of my invention is as follows: The needle cylinder A being put in rotation with a web formed on the needles, and i one yarn passing through hole g, and another through holesi and h, the needles rise and fall in the ordinary manner, as shown in Fig. 4, grasping the upper yarn W above the points F and drawing it down over said points, thereby forming loops, and grasping the under yarn 0 below said points F. The inside upper end of the needle cylinder is beveled, as shown at a, Fig. 3, and as each needle rises, it releases its tension on the loop W which it holds, and the tension of the web over the inclined surfaces A tilts the loop forward, as shown in dotted lines in Fig. 5, thus releasing the loop from the point F.
I have illustrated my invention as applied to a machine in which the needle cylinder and ring E rotate, while cam cylinder, ring D and yarn guides are stationary, but it may of course be applied to the equally well. known type of machine, in which the needle cylinder is stationary, in which case ring E would also be stationary and the cam cylinder, ring D and yarn guide would rotate, without departing from my invention.
What I claim as my invention, and desire to secure by Letters Patent, is-
The combination with a knitting machine having a needle cylinder and an upper and lower yarn guide, of a ring of greater diameter than the needle cylinder arranged above and concentric with the latter and carrying points arranged around its entire circumference at equal distances apart and projecting radially inward between said needles below the upper yarn guide and above the lower one, whereby the tension of the web acts to draw the loops inward from 01f the points as the needles successively rise, substantially as described.
