UNITED sTATEs PaanivrV OFFICE.
E. TIFFANY, OF THOMPSONVILLE, CONNECTICUT, ASSIGNOR TO HIMSELF AND GEO.` n
COOPER, OF SAME PLACE.
KNITTING-MACHINE.
Specification of Letters Patent No. 28,133, dated May 1, 1860.
To all whom it may concern:
Be it known that I, ELI TIFFANY, of the town of Thompsonville, county of Hartford, and State of Connecticut, have invented new and useful Improvements in the Mode of Constructing Knitting-Machines; and I do hereby declare that the following is a correct description thereof, reference being had to the accompanying drawing and the letters of reference marked thereon.
The nature of my invention consists in the arrangement of the needles, and the application of one press bar, to a fiat, ribbed knitting machine.
To enable others skilled in the art to make and use my invention I will proceed to describe the construction and operation.
Figure l is a front view of the machine; Fiv. 2, a section transversely of the same from front to back, to a.
In constructing my knitting machine to be used with power, I adhere to the general mechanical arrangement in use for the purpose.
The improvements I claim are in the arrangement and operation of the needles R, P, in placing them so as to work at right angles with each other, one set arranged and moving vertically and the other set arranged and moving horizontally, and each set crossing the other to form the stitches, also the use of one presser bar instead of two.
The plan Fig. l describes a front view with the levers, arms, &c., when commencing operations.
The plan Fig. 2 describes the levers, cams and other attachments, when about to commence operations.
The two revolving cams, M, M, are to actuate the vertical levers n, n, which are attached at the upper end to the single presser bar D, causing the same to rise and fall to press the barbs of both sets of needles as they work vertically and horizontally, and press ofi' the stitch from each of the sets of needles,
alternately, and the cams N, N, and their rollers are so formed as to give a momen tary stop to the vertical needles while the stitch is forming, to gain the loop and wait till the presser bar D, comes on to the backs of the needles, P, to press off the made stitch and gain a new one.
The presser bar D, presses the barbs of the horizontal needles as they pass inward and the barbs of the vertical needles as they descend. Thus by one simple movement of the cams and levers, the presser bar does the duty of two bars which are commonly used in knitting machines.
The stationary bar H extends the whole length of the needle bar F and is attached permanently to t-he sides of the frame. This bar is laced in an inclined position, and has a mo erately sharp smooth edge, and is close up to the underside of the horizontal needles R, so that when these needles make a return movement with the stitch formed, the edge of this stationary bar H presses off all the stitches from the needles at once, leaving them prepared for another stitch.
The bar I is placed in the same transverse position as the bar H but in a vertical manner, and attached at the lower end to arms or levers actuated by the cams M M, to give a rise and fall motion to push off the stitch from the vertical needles P, when they de scend, in the same manner as the bar H plushes olf thest-itch from the horizontal neeles.
The jack sinkers C, are composed of a series of thin metal plates, levers and hooks, with an angular notch E, at the lower end to push down the thread between the needles to assist in forming and perfecting the stitch. These jack sinkers are actuated by the slow cock B, which slides transversely, right and left on the bar L, by means of the long lever S which is attached to the arm T, at the bottom end and is actuated by the cam V, the periphery of which works against the pin O, and the spring W, gives the backward movement.
The cams N, N, have a nonacting surface a short distance, to cause the resting or momentary stopping of the vertical needles to gain the loop, and wait while the presser bar D, comes on to the barbs of the needles to press o the old stitch.
The general arrangements of the other parts of the machinery are in the customary mechanical manner.
This machine will make either plain or ribbed work, for cuits shirts or any other article.
The thread guide Y, slides on the bar Z, to carry the thread under the jack sinkers.
What I claim as my invention and desire of needles crossing each other at right anto secure by Letters Patent is-V 1. I claim the single presser bar D and its arrangements, whereby it is made to oper- 5 ate, and perform the duty of the two presser bars, that are now usually employed.
2. I claim the arrangement of the two sets gles, whereby the barbs of each are acted on by the single presser bar D, recprocally.
ELI TIFFANY. lVit-nesses:
WM. VINE, HENRY C. ROBINSON.
