IMPROVEMENT IN REGISTERS FOR KNiTTlNG-MACHINES.

Specification forming part of Letters Patent No. 82,555, dated September 29, 1868; ani'cduted September Q4, 1365.

To all whom it may concern:

Be it known that I, J. W. Ris/r, of Rochester, in the county of Monroe and State of New York, have invented a new and useful Count- 'Register for Knitting Machines; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawing, making part of this specification, in which- Figure l is a top view or plan of my invention, a small portion of the dial D being broken away, so as to show a port-ion ot' the ratchet-wheels Wand w. Fig. 2 is an inverted view of the same, showing a portion ofthe ratchet-wheel XV broken away, so as to expose the wheel w. Fig. 3 is a transverse section, taken in the plane of the line o in Fi l and 2.

Like letters indicate like parts in all the iigures.

This invention relates more especially to that class of knittingmachines which are capable of narrowing or widening; and it consists, mainly, in the employment or use of a suitable device for registering the count,7 or the number of rounds the machine is run to form the dili'erent parts or sections of the stocking, or whatever is being knit, whereby the operator is entirely relieved from the perplexing' task ot' keeping these counts mentally, and avoids entirely the annoyanees consequent upon miscounts or mistakes.

To enable others to make and use my invention, I will describe its construction and operation.

The bed-plate l may be made ot' any suitable material, and is perforated to receive t-he hand-stud s, and also for that of the hand h. This plate may be cast, and, it desired, provided with a raised rim or iange on the dialside to receive a glass.

The ratchet-wheel NV is raised from the plate B by aboss or hub cast upon the plate. The space between the plate and wheel should be sufiicient to permit the free action of the wheel un There may be a spherical steadying-collar, placed between the clamping-amt E and the wheel XV.

The nut E may be provided with a set-screw, a, which is screwed down firmly against the end of the hand-stud s, so as to act as a jamnut; or a jam-nut may be used, if desired.

The object of securing the adjustment of the clamping-nut E upon the studs is that the hand h may be turned backward without unscrewing, when it is desired to set the hand h. from any point where the machine may have been stopped back to its present position, as shown in Fig. 1.

The primary ratchet-wheel W' has one hundred teeth, and the stroke of the drivin g-sprin g b is limited by the U-shaped guard d, between the sides or arms of which a spur from the end of the spring projects.

The pawlj' is to prevent thcwheel XV from being turned backward by the spring I) on its return stroke. The pawl e is applied to the secondary wheel w for a similar purpose.

There is a dial, D, Fie". 1, having one hundred divisions in its outer circle. D has teu divisions, for the ten teeth of the secondary wheel w. It will be seen that either or both of these wheels may be made with a greater or less number ot' divisions, it desired.

The register, as herein shown, is designed more especially for the Lamb knitting-machine, and it is arranged to be attached tothe left-hand end otl the bed-frame of the machine by suitable bolts through the holes g.

There is a tappet attached to the slidin frame oi' the machine in such a manner as to strike the driving spring at l; at each righthand stroke or throwof the frame. Thismoves the hand forward one not-ch; therefore, when the machine makes one hundred full strokes or rounds the hand h will have made one revo lution, the pin z' will catch a tooth of the sccondary wheel w and turn it one notch, and, there being two teeth in this wheel, when the primary wheel makes ten revolutions the hand h will have made one.

'hen the operator has run oit' any desired number of rounds, the primary hand h may be turned forward to its startingpoint for a new count by means of the set screw E, and the hand 71, may be adjusted to its starting-point by vibrating the spring y, which may be done by a linger of the left hand.

The absolute necessity ot' keeping count when running' knitting-machines which are made to Widen and narrow in order to make duplicates is Well understood, and it is equally well understood that as a mental effort it is extremely difiicult and very uncertain; whereas, with my invention, the count is faithfully and perfectly recorded. Therefore, by following a table of sizes and proportions for the different portions of a soelr or other article, not only duplicates, but any nulnber, may be made exact-ly alike.

The pin fi, Fig. 3, projects from the inside face of Wheel W, and nearly opposite te that ot' the hand h.
