PHILIP A. BROOKS ATTORNEY Patented Oct. 10, 1950 Philip A. Brooks, Westwood, Mass. Original application August 6, loifllserial No.

Divided and this application February 12, 1949, SerialNo. 76,098

My invention relates to circular knitting machines and more particularly to means for protecting the knitted product from oil and the like which necessarily accumulates on both the moving and stationary parts of the machine. Such 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 stationary container having a stationary cam projecting from its upper end, and especially those in which the winding rollers of the take-up 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 an elevation of a portion of a circular knitting machine embodying one form of my invention certain parts being shown in section.

Fig. 2 is an elevation, partly in section, of a portion of the container provided with a winding roll bracket slightly difierent in form from that shown in Fig. 1.

Figs. 3 and 4 are plan views of the cam oil guards shown in Fig. 2 which prevent the product from coming into contact with the inner surface of the stationary cam while the product 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 descriptive and by no means restrictive, I I is a bottom needle cylinder of a circular knitting machine, said cylinder enclosing the 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 M, the members 13 and M comprising an inverted funnel-like member, which is shown in the present instance as supported by the bracket. I5.

Preferably, the rim of the substantially coneshaped member [4 is up-turned to form an annular basin for receiving the oil which flows around the outer surface of the said funnel-like member. The rim 16 of the cone may be proealms. (Cl.66--153) vided with an overflow lip It, ariaim such Icase, a trough it may be placed beneath said lip for conducting the overflow into a receptacle 19. It is desirable that the substantiallyl cone shaped 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

takeup 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 takeup 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 projecting from the upper end of the product container 20.

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 2i 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 grease accumulated on the inner surface of said cam.

In Fig. 2, 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.

This application is a division of my application Ser. No. 766,606Qfiled August 6, 1947, upon which Letters Patent No. 2,481,718 wereissued September 13, 1949.

. 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 by rollers having in-.

.3 termittent motion controlled by a stationary cam projecting from the upper end of said container, means for protecting such product from the accumulated oil on said cam while the product is being removed from said container, said means comprising a guard overhanging said cam.

2. In a circular knitting machine having a needle cylinder and a container into which the knitted product is drawn by rollers having intermittent motion controlled by a cam, means for protecting such product from the accumulated oil on said cam While the product is being removed from said container, said means comprising a segmental guard overhanging said cam, said guard having a straight edge and flange depending therefrom, said straight edge being spaced from the interior periphery of said cam.

3. In a circular knitting machine having a .needle cylinder and a container into which the Iknitted product is drawn byrollers having intermittent motion controlled by a cam, a winding-roller bracket, means for protecting such product from the accumulated oil on said cam 4 while the product is being removed from said container, said means comprising a pair of segmental guards overhanging said cam, one of said guards having a straight edge, a flange depending therefrom, said straight edge being spaced from the interior periphery of said cam, and the other guard being secured to said bracket substantially diametrically opposite the guard first mentioned.
