WILSON WORTH BURSON PATENT OFFICE.

, OF ROCKFORD, ILLINOIS.

KNITTING-MACHINE.

Application med September To au whom it may concern:

Be it known that 1, WILsoNWoR'rH BonsoN, a citizen of the United States, residing in Rockford, in the county of Winnebago and State of Illinois, have invented a new and useful ln'iprovement in Knitting-Machines, of `.vhich the following is a specification.

This invention relates to that class of knitting machines known as straight knitting machines, the same having two parallel rows of needles mounted on suitable frames, with an opening between them for the knit fabric to pass through.

My object in the invention `has been to provide an improved and quick acting mechanism whereby the pattern cylinders may control the positioning of the needles, and its nature is fully disclosed in the description thereof given below and illustrated 1n the accompanying drawing forming a part of the description, and in said drawin s, Figure 1 is a partial side elevation of tie machine embodying my invention. Fig. 2 is a section thereof on the line Q-L of Fig. l. .F 3 is a. iartial cross section of `the machine showingthe needle mechanism and a portion of the pattern cylinder, and Fig. 4 is a section on the line 4-4 of Fig. 3. Fig. 5is an elevation of one of the division plates, and'Fig. 6 a section 'on the line tis-6 of `F ig. B.

In said drawing, 5, 5 represent portions of the frame of the machine, and yrepre` sents the base bar and 7 and 8 the spacing bars fdrmin r the needle beds.

The grooves notching the rear l 2O ,and entering y. the rib 21 of the spaengg de rods/ 19 Whicliwpass enter the openings 28 in the pattern cylinder Y lever 39 and operates the yarn guides. There are two of the pins 35, and they are located aS shown so that they rock the shaft at each end of the stroke of the crosshead, the rocksma er than` ing of the shaft causing the lifting of the controllers so that they are all freed from the pattern cylinder. As the cross head reverses its motion almost immediately after liftin the controllers, the rock shaft will then e free to rock back to its normal position, and allow the controllers to fall back, such of them as are over o enings 28 in the pattern cylinder entering t e same and carrying their corresponding jacks down out of engagement with the cams 13, and the others resting upon the surface of the cylinder and continuing their corresponding jacks in service. By this construction the controllers are rendered quick in their movements so that theneedles are correspondingly quiekened, Vand the machine is rendered capableo more work than machines previousl used. ghe openings'28 can be made eretofore, and be arranged in such close proximit to each other as to permita material re uction in the size and wei htof the pattern cylinder.

Tie lever 39 is joined to va crank gear wheel 40 receiving povler from a pinion 4l,

- and the pattern c Y11nd r is driven by a gear -42 on the same aft therewith.

It will be understood that mechanism such as that described for controlling and actuating the needles is employed upon both sides of the work.

The recess 22 in addition to ivin room to the front ends of the jacks W en t ey are depressed, serves the further and very useful purpose of preventing the needles from being drawn orward by the yarn, when the jacks are out of action.

I claim g- 1. In a. strai ht knitting machine, the combination wit the needles, the jacks and the pattern cylinder, of controllers normally in contact with the pattern cylinder and into which controllers the jacks enter and by which they are positioned, and means independent of the pattern c linder for liftin said controllers vertical y from the cylintgler at each stroke of the yarn guides.

2. In a strai ht knitting machine, the combination with the needles, the jacks and the pattern cylinder, of controllers normally in contact with the pattern cylinder and into tically from t e cylinder, and individual springs for forcing the controllers to the" cylinder.

4. The combination with the needles, the 'acks, and the pattern cylinder adapted to e engaged by the controllers, of vertically moving controllers receiving the jacks and positionin them, a rock shaft o erated intermittent and independently o the cylinder, and a apted to lift the controllers vertically from the cylinder, and individual sprin s for forcing the controllers to the cylin er.

5. The combination with the needles, the

ljacks and a pattern cylinder adapted to be engaged by controllers having a vertical movement and actin to receive the jacks and to position them y such vertical movement, of said controllers, means other than the cylinder for momentarily lifting all of the controllers vertically to free them from the cylinder, and means for retracting them toward the cylinder.

6. The combination with the needles and the pattern cylinder, of the jacks operating the needles, the vertically sliding controllers normally in contact with the pattern acks with the actuating cam and their reease therefrom, said cam, and, means independent of the cylinder for liftin "the controllers vertically from the cylin er at the conclusion of the yarn guides stroke.

7. In a knitting machine needle bed, the base bar and the spacing bars, `in combination with division plates stationaril sured ,in the'spacing bars, and the control ers movabiypositioned between the division plates, and guide rods passing through both the plates and the controllers.

8.'Tl1e combination with the jacks of the spacing ba1s'8 located over the forward ends of the Jacks and having longitudinal grooves giving room to the jacks in their changing ositions, and holding the needles from belng drawn forward by the arn.
