IMPROVEMENT IN MECHANISMS FOR OPERATING TAKE-UP ROLLERS FOB KNITTING-MACHINES.
I Specification forming part of Letters Patent No. 177,591, dated May 16, 1876; application filed September 4, 1875.
To all whom it may concern:
Be it known that we, IRA TOMPKINS and ALBERT ToMPKINs, of Troy, in the county of Rensselaer and State of New York, have invented a new and Improved Take-Up for Knitting-Machines, of which the following is a specification;
Our invention consists of the tension-spring employed to regulate the tension of the cloth, interposed between the crank-rod andthe rod for working the take-up pawl-lever, and so arranged that when the machine does not deliver cloth for any reason, as when not making stitches, the spring will compress and allowthe crank-rod to work its regular course, while the pawl-lever will be held by the tension of the cloth until the cloth delivers from the machine again.
Figure 1 is a front elevation of our improved machine. Fig. 2 is a side elevation. Fig. 3 is a top view, and Fig. 4 is a section of the cloth-roller and the emery'rollers used in the machine.
Similar letters of reference indicate corresponding parts.
A represents the cloth-roll, and B and O the emery-rolls, employed for taking up the cloth by drawing away from the machine with a certain degree of tension, regulated by a spring or weight, as fast as the cloth is made, one of said rollsbeing worked by a ratchet-wheel, D, pawl E, spring-detent E, and pawl-lever F.
In the take-up gear we use a stationary wheel on the spindle, whereon the take-up frame turns, and around which the wheel of horizontal shaft at top of take-up frame is carried by the latter, and is thereby made to revolve, while the take-up frame itself is revolved by the fabric which is'operated on by the machinery.
In order that the take-up apparatus shall not work, and thus strain the cloth with overtension at times when the machine does not deliver asfast as at others, we propose to connect the pawl-rod H and the crank-rod I, by
out lifting the pawl, and thus allow the crankrod to work when the cloth does not deliver without straining the cloth; and we put an other adjustable stop, 0, on the pawl-rod uhder the arm N, for the latter to push the awllever down, as it would otherwise be held up by the spring. The arm P serves for a guide to the rod H.
In practice, the take-up will be geared to take up a little faster than the machine delivers, to be compensated by the stoppage of the pawl-lever.
The advantages of this contrivance over all others are: it avoids making distorted lines in the goods and narrowing up the web by our tension; the take-up runs easier, is more sensitive, less troublesome to set and keep in order, does not require so'heavy a spring, and makes a more even stitch, and hence produces better goods.
Having thus described our invention, we claim as new and desire to secure by Letters Patent- The combination, with ratchetwheel D, pawl E, spring-detent E, and pawl-lever F, of the rods H I, connected by a spring arranged between pawl-rod stop L and crankrod arm N, the stop 0, and arm P, as shown and described, so as to lift or pull on ratchetpawl and cause spring to exercise a lengthwise tension upon the cloth.
