CIRCULAR-KNITTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 393,010, dated November 20, 1888.

Application filed Septemher 15, 1887. Serial No. 219,753. (No model To in whom, it may concern.-

Be it known that 1, DAVID H. HILL, a citizen of the United States, residing in the city and county ofP-hiladelphia, State of Pennsyl- Vania, haveinvented a new and useful Improvement in Circular-Knitting Machines, which improvement is fully set forth in the following specification and accompanying drawings.

My invention consists in dampening and to tension regulatingdevice for the yarn or thread supplied to a knitting-machine constructed as herein described and claimed.

Figure 1 represents a front elevation of a knitting-machine embodying my invention.

1 5 Fig. 2 represents a side elevation thereof,

partly sectional in line a :c, Fig. 1.

Similar letters of reference indicate corresponding parts in the several figures.

Referring to the drawings,,A represents a knitting-machine, which, excepting the features of my invention applied thereto, is of usual construction.

B represents the driving-shaft of the machine, on which is feathered the bevel-wheel O, which maybe engaged with and disengaged from the bevel-wheel D of the cylinder of the machine, so that the machine may be started and stopped. Theshaft B also carries a clutch, 1 one wheel or pulley, E,whereof is feathered on said shaft and the other wheel or pulley, E, is loose thereon.

F represents a lever which is pivoted to the frame of the machine and to an arm, G, the ends of which carry shippers H J, respectively. The shipper H engages with the groove or neck a of the hub of the wheel 0, and the shipper J engages with the groove or neck I) of the wheel E.

It will be seen that when the lever F is operated in one direction the wheel 0 is caused to mesh with the wheel 1), whereby the ma chine is started. The pulley E is also clutched -with the pulley E", and thus the latter is retated simultaneously with the starting of the machine A. It is evident that by moving the lever F in the opposite direction the machine will be stopped and the clutch separated, whereby the pulley E" is at rest.

K represents a frame which rises from the frame of the machine, and supports at its upper end a trough or pan, .L, and also a cylinder, M, which dips into said trough. Secured to the journal of the cylinder M is a pulley,

N, around which passes an endless belt, P, which also passes around the clutch-pulley E and guide-pulleys Q, the latter being mounted on the frame K intermediate of the pulleys Meshing with the gear-wheel R on the cylinder of the machine is a pinion, S, which is secured to a vertical shaft, T, the latter being mounted on the frame of the machine and 'carrying at its upper end a guide and tension roller, U, adjacent to which is an eye or guide,

V, it being noticed that the yarn supplied to 6 the machine passes over or around the cylinder M, then through the eye V, and next around the roller U, from whence it is directed to the needles.

The trough or pan L contains grease, oiling, or other material for dampening the yarn, so that as the yarn is brought into contact with the cylinder M the yarn is dampened, in which condition it is supplied to the needles. When the machine is started, the roller U and cylinder M simultaneously rotate, and the yarn is drawn by said roller and dampened by said cylinder. WVhen the machine is stopped by operation of the clutch E, through the medium of the lever F, the roller U and cylinder M 8c cease their rotation, and thus the advance of the yarn and dampening of the same discontin ue.

Having thus described my invention, what I claim as new, and desire to secure by Letters 8 5 Patent, is

1. A dampening device for the yarn of a knitting-machine, consisting of a cylinder or roller and a trough, a pulley on said roller, a driving-shaft with clutch mechanism thereon, 0 the latter consisting of a fast and a loose pulley, a band on said roller-pulley and on the loose pulley of the clutch mechanism, and a shifting device for said cl uteh mechanism, said parts being combined substantially as de- 5 scribed.

2. The combination of the cylinder M, having the pulley N on its journal, with the trough L below said cylinder, the driving-shaft B,with

grooved bevel-wheel O, loose clutchpulley E ICO I and fast clutch-pulley E thereon, the band B on said pulley N and on said loose clutch-pulley, mechanism, substantially as described, for shifting said fast clutch-pulley and said grooved bevel-wheel, and a needle-cylinder having a bevel-wheel, D, connected therewith and gearing with the bevel-wheel O, substantially as and for the purpose set forth.

3. The combination of the driving-shaft B, with the grooved bevel-wheel O thereon, a clutch mechanism consisting of a fast and a loose pulley on said driving'shaft, a dampening-cylinder and a trough, a pulley on said cylinder, a band on said cylinder-pulley and said loose clutchrpulley, a lever pivoted to the frame of the machine, an arm attached to said lever and provided with shippers adapted to operate said grooved bevel-wheel and said fast clutch-pulley, and a needle-cylinder having a bevel-wheel gearing with said grooved bevel- DAVID H.
