*3 Claims.

My invention relates to circular knittingmachines and moreparticularlyto means. for protecting the knitted productirom oil andthe-like which necessarily accumulates on both the-moving and stationarymarts. otithe'machine. JSuch attachments have heretofore been proposed for protecting the product of a'circular knitting machine from grease and oil, but these are not well adapted for use in the improved machines now commonly employed for knitting hose. It is therefore the object of my invention to provide attachments that are particularly applicable to circular knitting machines having take-up devices for drawing the knitted product mechanically into a container, and especially those in which the winding rollers of the takeup mechanism rotate intermittently on their horizontal axles and continuously about a vertical axis.

In the drawings accompanying and forming part of this specification, I have illustrated my invention as applied to one well-known type of circular knitting machines, but it is to be understood that I do not limit myself thereto.

Figure 1 is a perspective view of those parts of a circular knitting machine that constitute my invention, various other portions of the machine being indicated in dotted lines.

Fig. 2 is an elevation showing my invention on a larger scale, certain portions being in section.

Fig. 3 is an elevation of a product supporting member and oil guard.

Fig. 4 is an elevation partly in section of a portion of the container and the winding rollers whereby the product is drawn into the container.

Figs. 5 and 6 are plan views of oil guards which prevent the product from coming into contact with the inner surface of the stationary cam while it is being removed from the container.

In the particular drawings selected for more fully disclosing my invention and the principles underlying the same, said drawings being merely illustrative and by no means restrictive, I0 is a circular knitting machine having a bottom needle cylinder ll enclosing a sinker sleeve l2 within the lower portion of which is disposed the upper portion of a tube l3, said tube terminating in an inverted truncated cone HI,- the members [3 and I4 comprising an inverted funnel-like member, which is shown in the present instance as supported by the bracket l5.

Preferably, the rim of the substantially coneshaped member I4 is up-turned 'to form an annular basin for receiving the oil which flows around the outer surface of the said funnel-like TT ING MACHlNE h r ks, Westwood, Mass.

1947, s rial-No. "1 ,696 (c 6. 1 member. The rim .I6 of the. cone may be provided with an overflow lip l1, and; in such case,

.atrough [8 may be placed :beneath saidlip for conducting the overflow into a receptacle, i9.

' .Itis desirable that; the :substantially. coneshaped member I l be disposed immediately above the product container 20 and spread outwardly above the open end of the latter.

Mounted on the top of the container is a winding roller bracket 2| on which are mounted for rotation about their

axles

22, 22, the take-

up rollers

23, 23, whereby the knitted product indicated at 24 is drawn from the bottom needle cylinder into the container.

By means of mechanism well understood and therefore unnecessary to be shown, the take-up rollers and their support revolve around a vertical axis continuously. By means of other mechanism, not shown, the rotation of the rollers 23 about their axles is intermittent, such mechanism being controlled by the stationary cam 25.

As oil invariably accumulates on the inner surface of said cam, means are provided to protect the product while being removed from the container from the oil which collects on the inner periphery of said cam. One form of such protecting guard is shown at 26, being in this instance substantially segmental in shape and provided with a flange 21 depending vertically from its straight edge, such flange being slightly spaced from the inner surface of the cam. The arrangement is such that when the operator draws the finished stocking or other knitted product from the container, the stocking passes over the guard and does not take up any of the oil or rease accumulated on the inner surface of said cam.

In Fig. 4, I have shown another form of winding roller bracket to which are secured the flanged guard above described and a segmental guard 28 secured to said bracket approximately diametrically opposite the guard 26. In the present instance, the guards are shown attached to the bracket by the screws 26', 28', respectively.

The quality drum 29 is actuated by a chain 30 co-operating with suitable sprockets, an arrangement which requires substantial and continuous lubrication. To conveniently support the finished knitted product at a point close to the container and protect the same from oil, I have provided a hook 3! suitably attached to the machine and passing through a slot in a vertical plate 32, said plate having a flange 33 on one of its vertical sides, said flange being interposed between the 55 sprocket and the product.

Having thus described illustrative embodiments of my invention without, however, limiting the same thereto, what I claim and desire to secure by Letters Patent is:

1. In a circular knitting machine having a needle cylinder and a container into which the knitted product is drawn mechanically, means for protecting such product from oil, said means comprising an elongated tube the upper portion of which is disposed within said cylinder and adapted to receive such product and direct it to said container, and an inverted substantiallyconically shaped member secured to said tube of said prising a member having a shank and a conical portion, a portion of the shank of said memberbeing within said cylinder and the conical portion thereof being intermediate said cylinder andsaid container, the rim of said conical portion being up-turned to form an annularbasin for receiving the oil flowing along the outer surfaces of said tube and said member, said member being adapted to receive such product and direct it to said container, a receptacle gbelow said conical 7 portion and means for directing theoil over flowing said basin to said receptacle. 7 PHHIIP A.
