IMPROVEMENT IN KITTING-MACHINES.

Specification forming part of Letters Patent No. 131,955, dated October S, 1872.

To all whom it may concern:

` Beit known that I, LEANDER B. HUNT, of` Hyde Park, in the county of Norfolk and State of Massachusetts, have invented certain new and.` useful Improvements in Knitting- Machines, of whichthe following is a specification:

- .Nature and Objects of the Invention.

Y' My invention consists in a simple and eftlcient means for raising the needles of knittingmachines from the4 lower or working groove to the upper` or retaining groove, or vice versa, as well as for setting and removing all or part i of them.

On the drawing, Figure 1 is an outside View; Fig.` 2 is an inside view of a section of a knitting-machine` cylinder; Fi g. 3 is a cross-section over the line A B von Fig. 2.

' Similar letters refer to similar parts wherever they occur on the drawing;

The drawing is made to represent a segment or portion of theworking-cylinder of a knitting-machine with my improvement attached thereto. l

` Vc is a part of the working-cylinder, where b is the upper or retaining groove and c is the lower or workin g groove. that is made to be removed easily when the d is a part of a ring needles are to be put in the machine. e c are two slides or dampers in the lower part of the cylinder a. These slides are made to move up and down in the slots c c', forming an angle with thegroove c of about half a right angle. y The dampers c e proj ect through the body l a, and have on the outsideknobs f j', whereby they may be operated from the outside of the machine. A bridge-plate, lc, held to the cylinder a by means of the screw l, is made for the purpose of steadying the motion of the dampers e e when moved up or down in the slots e e. Between the grooves b and c is a ange or division, j, which is out through at one place, g, so as `to make a connection between the lupper and lower grooves for -permitting the passage of the needles from one groove to another'. Atthe above-named place where the flange j is cut through is a gate, g,

that moves in a corresponding slot in the bodyv of the cylinder c. rJlhe gate g is at the outside guided in a slot in a bridge-plate, h, and is provided with a knob, c', whereby the gate can be operated, and, by means of this gate g, the communication between the upper and lower grooves may be shut or opened at pleas- 1118.

Having described the construction of my invention, I will now proceed with the operation of the same. First, to set the needles-that is, to place all or a number-of needles in the working-groove c-remove the ring d and place all the needles in the now open retaininggroove b, replace the ring d, open the gate g, and move the dampers e e, So 'that they do not obstruct the working-groove c. When the cylinder c now is revolved around the ordinary stationary needle-cylinder, one needle after the other will drop automatically down into the groove c through the passage at g. If, on' the other hand, the needles are to be moved from the working-groove c up to the retaining-groove b, push one of the dampers c e up 'so as to close the passage c, as shown in dotted lines on Fig. 2, open the gate g, and revolve the cylinder c as in the previous case, when one needle after the other will move upward on the projecting part 4of the damper e, through the gate g, into the upper space b. i

It is oftentimes needed to revolve the knittin g-machine to the right or to the left, and I am therefore obliged to use two dampers, e

,6, one corresponding to the right-hand motionv andv the other to the left-hand one.

The advantages I gain over common knitting-machines are that I can set all needles at once, automatically, and that I can take in everyother, every second, third, fourth, &c., needle during the. operation without losing any stitches, with greater speed, and in an easier way than heretofore.

In a previous patent issued to me July 25, 1871, numbered 117,293, I use instead of the narrow partition j a wider one with dampers at the top and bottom; but' I find this my new device much better, because I do not get the space at g cramped with needles, but I am able to drop or raise needle for needle, or
