COLLARETTE-KNITTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 442,167, dated December 9, 1890. Application filed November 25, 1889. $eria1 No. 331,441 (No model.)

To aZZ whom, it may concern.-

3e it known that I, JOHN BRADLEY, of Chelmsford, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Oollarette- Knitting Machines, of which the followingis a specification.

My invention, in general, has relation to means for producing fancy-stitch work on spring-beard-needle knitting machines, and in particular the invention has reference to collarette knitting machines, so called, which are designed to produce trimmings for knit underwear.

It is the object of the invention to produce improved means for throwing figured presser-wheels into and out of operation in connection with the needles, which means shall be simple in construction, economic of manufacture, and certain and efficient in operation, and which shall at the same time be so organized as to effect the knitting of a variety of patterns.

The invention eomprehends the employment of a plurality of figured pressers eapable of being moved into and out of operation in connection with the needles, so that the effect of plain pressing may be accomplished at predetermined intervals, as well, also, as a variety of tuck or figured pressing, the movement of the pressers being secured by a mechanism peculiar, though simple, in construction and organization, all as is hereinafter fully and particularly set forth.

Reference is to be had to the annexed drawings and letters of reference marked thereon, forming apart of this specification, the same letters designating the same parts or features, as the case may be, wherever they occur.

0f the drawings, Figure 1 is a perspective view of the invention, shown in connection with a spring-beard-needle knitting head or cylinder, the ordinary appliances for operatin g in connection with the needles to produce a knit fabric being, for the sake of clearness, omitted. Fig. 2 is a sectional side elevation tending to show the construction of the presser-support-s, their relation one to another, and also a part of the means whereby the pressers may be moved. Fig. 3 is a plan view of the pressers, their supports, and operating means. Figs. 4 and 5 are seetional details hereinafter more particularly described.

In the drawings, a designates the needle head or cylinder, and l) spring-beard needles vertically arranged in the head, as usual. In the production of a fabric on a machine of this kind a yarn-guide, stitch-wheel, presserwheel,and landing and knocking-over wheels are employed in away so well known to knitting artisans as not to need description herein, and to avoid complication and confusion I have omitted all of the said devices from the drawings excepting the presser c, and instead of employing a plain-faced wheel, as is usually done, I make use of a plurality of figured pressers, which, when acting conjointly, produce the same result as a plain presser, but which singly are constructed so as to mispress the needles in different order. In the present instance I employ two such figured pressers d e, the former being supported by and adapted to be rotated upon a study, secured to the inner end of a lever g, and the latter being in like manner supported on a stud h on the inner end of a lever 11. Both levers g and "i are fulerumed upon a stud j, attached to a star-130x70, adjustable toward and from the needles, as is common with such devices in knitting-machines.

Z Z are bell-crank levers fulerumed at n on a bracket 0, connected with the bed of the machine. The upper end of the lever Zis conneeted by means of a link m with the lever g, and the lever Z is connected by means of a link it with the lever 1 The links are pivotally connected with their respective levers g i, the pivot o of the link 11. extending through a slot formed in the lever g, as is most clearly shown in Fig. 4. Clips 7, secured to the lever g and extending over the pivotpins of the links, serve to keep the latter in place on the said pins.

The ends of the horizontal portions of the bell-crank lcversl Z are provided with vertical'studs a 1', which are arranged to rest and ride upon the uppersurface of a pattern-disk s, as also upon and over the pattern-blocks 2, adapted to be secured to the disk 8 in the holes 11, formed therein.

The periphery of.

, block 25 passes under a stud ror r the bellcrank lever with which such stud is connected will be operated so as to move the presserthe disk 3 is provided with ratchet-teeth, which are engaged by a spring-pressed pawl 12, pivoted on the outer end of a lever 21;, fulcrumed on the bed of the machine, the inner end of said lever 10 being provided with a bowl or roller 5r, arranged to be acted upon by a cam 3 on the head or cylinder a as the latter is rotated. A spring .2 (shown by dotted lines in Fig. 1) serves to actuate the lever 10 in a direction contrary to that in which it is moved by cam y, the latter operation serving to move the pattern-disk s a distance corresponding to the length of one of its ratchetteeth.

In operation, when plain knitting is to be performed, the pressers d 6 will act conjointly andas a plain presser; but when it is desired to produce tuck or fancy-stich Work one of the presscrs will be moved out of the way, so that but one can operate upon the needles, and this one will press certain of the needles and mispress others, and then both press'ers may be again brought into action, as before,

or they may be made to change places, so that the one previously in operation will bethrown out of action, and the one formerly out of action will be brought into operation and press and mispress the needles in a different order. VVh-e-n the vertical studs 1' r are upon the face of the patterndisk, the levers g 2' will be moved to a position which will bring both pressers into operation; but when a patterncarrying lever-,- w-ith'which it is connected through the medium of a linkrodi, in such manner as to throw its associated presserout of operation. By properly arranging thepattern-blocks on the pattern-disk the presse-rs can be thrown out of and brought into oper ation at any predetermined time or in any predetermined order.

Itis obvious that by varying the color of the yarns employed in accordance with the changes made in the position of the pressers the effect of the fancy stitching may be heightened.

Changes may be made in the form and arrangement of parts comprising my improvements without departing from the nature or spirit of the invention.

Having thus explained the nature of my invention and described a way of constructing and using the same, I declare that what I claim is-- 1. The combination, with the needle-cylinder and needles, of a plurality of pressers, levers pivot-ed at one end and each supporting a presser at the other, a rotary patterndisk, a plurality of levers adapted to be acted upon by the said pattern-disk, and means connecting the latter levers with the presser-car rying levers, as set forth.

2. The combination, with the needle-cylinder and needles, of a lever pivoted at one end and supporting a presser-wheel at the other, a rotary pattern-disk, a bell-crank lever, and

a link connecting one end of the said bellcrank lever with the said presser-support-ing lever, the other end of the said bell-crank lever being arranged to be acted upon by the said rotary pattern-disk, as set forth.

In testimony whereof have signed my name to this specification, in the presence of two subscribing witnesses, this 12th day of November, A. D. 1889.

JOHN BRADLEY.
