Application April 8, 1950, Serial No. 154,863

2 Claims. (01. 66---1) My invention relates to circular knitting machine and more particularly to means for protecting the knitted product from oil, and the like, which necessarily accumulates on both moving and stationary parts of the machine.

The object of my invention is to provide an attachment for machines of the type described in my Patent No. 2,481,718, September 13, 1949, whereby the knitted product, drawn mechanically into a cylindrical product-receiving container, is protected from the oil or grease that seeps into the container and accumulates on the wall and bottom thereof.

This object is attained by placing in the container a cylindrical casing spaced away from the wall and bottom thereof, such casin preferably being foraminous.

While my invention is described as applied to the well known type of circular knitting machines disclosed in my prior patent, its utility is not limited thereto.

In the drawings accompanying and forming a part of this specification, which show one embodiment of my invention which has given good results in practice,

Figure 1 is a central vetrical section on the line l-I of Fig. 2.

Fig. 2 is a plan view, the take-up rollers being omitted.

In the particular drawing selected for more fully disclosing my invention, which are to be considered as illustrated, merely, and not restrictive, l represents a product-receiving container which, in this type of machine, is secured by the screws H, II, to a casting l2 associated with the well known mechanism for actuating the take-up rollers indicated at l3|3, which are usually mounted on a winding roller bracket (not shown) for intermittent rotation about their horizontally disposed axles I4-I4, said bracket take-up rollers and container rotating continuously about a vertical axis.

Disposed within the container is a cylindrical member 14' having its upper end open to receive the knitted product and its lower end closed. The length of said cylindrical member is substantially the same as that of the container. Any uitable means may be used for spacing the wall of said cylindrical member away from the wall of the container, such as the pins 15, of which three are shown spaced equidistantly around the circumference of said container. The fourth spacin means is formed, in the present instance, by bending the longitudinal meeting edges of the cylindrical member radially, a shown at I6, and securing them together by solder, or the like, as indicated at l1. Obviously, a fourth pin I5 could be employed instead of forming the projection at 16 on the wall of the cylindrical member.

The base of said member may extend out to the wall of the container, as shown at 18, to cooperate with the pins [5, in order to secure the proper spacing of the entire area of said member from the wall of the container.

For spacing the closed lower end of said cylindrical member from the bottom of the container, any suitable means, such as the pin 19, may be employed. 3

Although the member l4 and its lower end closure are shown as formed of wire mesh, it will be obvious that said member may be made of other material.

In operation, the knitted product i drawn into the cylindrical member M by the take-up rollers and will assume substantially the shape indicated at 20, as it enters said cylindrical member, and eventually will pack together, as indicated at 2|, until the cylindrical member is filled.

The oil which seeps into the container through its juncture with the casting l2, chiefly, it is believed from the gearing or the quality drum (not shown) will, in time, coat the inner wall of the container and accumulate on the bottom thereof in quantities which, although small, render necessary the expensive operation of scouring the knitted product.

By means of my invention, it is impossible for the product to com into contact with any part of the container. It has long been the practice to remove product-receiving containers at frequent intervals for cleansing, which productionreducing operation is obviated by the present invention.

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

1. In a circular knittin machine having a product-receiving cylindrical container into which the knitted product is drawn mechanically, a cylindrical member disposed in said container, said member having an open upper end and a closed lower end, the length of said member being substantially equal to that of the container, means spacing the wall of said member away from that of said container, and means for spacing the closed lower end of said member away from the bottom of said container.

2. A device according to claim 1, wherein said cylindrical member and its closed lower end are formed of wire mesh.
