TO ALL WHOM IT MAY GGNOERN:
Be it known that we, BENJAMIN F. WYMAN, ot' Lancaster', county' of Worcester, and RENJAMIN H. HARTS- noRN, of Ashland, county of Middlesex, and State of Massachusetts, have invented a new and improved Register for Knitting Machines; and we do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.
The present invention relates to a neu and useful improvement in registers for h nitting machines, and we employ a worm-gear, placed upon the crank-shaft of a huit-ting machine, and secured to the same by a set-screw; also, a toothed wheel or dial, containing, say one hundred teeth, out to fit and run in the \.vorm-gear, before mentioned, with the upper side divided into, say, one hundred parts or divisions, which divisions are numbered in ascending series from five to one hundred; also, a suitubiy-constructcd stand, which can be secured to the leaf of a table by the side of a knitting machine by a thumb-sere against the underside et same, upon which stand the toothed wheel or dial is mounted, and made to revolve by the worm-gear en the crank-shaft of machine, and moves one division at every revolution of the crank-shaft; and also a hand or pointer, closelyfitted to the upper end of the perpendicular part of the stand, (upon which the horizontal toothed wheel or dial revolves which can be turned by the operator at any time, so the point of the hand shall be against the-figure 1 when the knitting is commenced. The hand of course stands still, while the dial turns one division at every revolution of the crank-shaft, thus registering with precision the number et times the machine has kuit around the stocking.
We do not confine ourselves Vto dividing the dial into just one hundred parts, but may use any number of divisions, always having the same number of teeth upon the edge as divisions upon the dial.
The usefulness of our invention is apparent: first, when we know that without it the operator is obliged to count the turns of the crank-shaft to get the stockings ot' the saine length, which is a tedious and annoying tax upon the operator; second, when we consider its accuracy, cheapness, and simplicity.
In the accompanying plates o drawing we have represented our improvements, reference being hadto the saine in the-following description, of whieh Figure 1 is a front elevation of a knitting machine with our improved register attached.
Figure 2 an end view of the same. i
`Figure 3 is a plan or top view of table-lent` and the lower part of knitting machine, out throng dotted line A B, figs. 1 and 2, with our improvement attached.
a a represents the leaf oi' a table, upon which the knitting machine I1 b is secured by the thumb-screws c c. d d the sliding frame of a'knitting machine, which operates upon the needles as it passes from one side to the other. c is a stud, secured to the frame (Z. f is the crank-shaft of the machine, passing through the hangerg and supported at the other end in the machine frame Z at h. z' is a worin-gear, secured to the crankshaft by the set-screw j. c 7c is a crank, secured tc thesbat'tj` at one end, and having a handle, I, at the other. m is a connecting-rod, hung at one end upon the stud e, and the otherend to the crank k in the centre at o. 2; is a stand, made to it looseiy upon a table-leaf', and secured to it by a thumb-screw, rl. o' is thetoothed dialwheel. .sis a hand or pointer, secured to the stand p by the piu Having described the manner in which the devices composing our invention and sonic. parts of a knitting machine are arranged,`\ve will new proceed to describe hon' the same operate together. The operator of a knitting machine turns the crank-shaftf by the handle Z, and crank In, and the sliding frame d d is made to more backward and forward by the connecting-rod m, which is hung at one end upon the stud e, and at the other end to the crank L" 7c at o, and upon the shaitf is secured the worm-gear z'- by the screw j. This worm tting the n the red toothed wheel or dial, the same is made to revolve, vor to move one division to every revolution of crankshaft.
The hands being secured to the stand u stands still wherever it is placed by the operator, and the dial revolves under it, showing at any time how many revolutions the crank-shaft nas made.
Having thus described our invent-ion, we claim as new, and desire to secure by Letters Patent- Thecombination and arrangement of the shaft f, the worin i', the dial r, the hand s, and the stand lo, su'0- sta-ntially as and for the purpose set iorth.
