GEORGE E. RUTLEDGE, OE CHICAGO, ILLINOIS, ASSIGNOR TO THE GEORGE I). WHITCOMB COMPANY, OF SAME PLACE.

SPECIFICATION forming part of Letters Patent No. 673,140, dated April 30, 1901.

Application filed December 16, 1899. Serial No. 740,491. (No model.)

To aN, whom, it may con/cern:

Beit known that I, GEORGE E. RUTLEDGE, a citizen of the United States, and a resident of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Knitting-Machines,of which the following is a specification, and which are illustrated in the accompanying drawings, forming a part thereof.

This invention relates to that type of knitting-machines in which two banks of needles are employed, the several needles reciprocating across an intervening slot between the two banks, through which slot the knitted fabric is drawn, and it relates particularly to that part of such a machine which is known as the fabric-depressor; and it consists in the mechanism hereinafter fully described, and which is illustrated in the accompanying drawings, in which- Figure 1 is a detail transverse vertical section of a knitting-machine, the yarn-carrier and fabric-depressor being shown in end elevation. Fig. 2 is a detail plan view of the same. Fig. 3 is a detail longitudinal section of the yarn-carrier and needle-plate, the fabric-depressor being shown in side elevation; and Fig. 4: is a transverse vertical section on the line 4 4 of Fig. 3.

The supporting-rails for the upper edges of the needle-plates 11 are shown at 10, the

slide-bars for driving the cam-carriages at 12,I

the upper guide-rails at 13, casting-off jacks at 14, and the frame of the yarn-carrier at 15. The yarn-carrying mechanism, aside from the frame, I have not deemed it necessary to show in this case.

The fabric-depressor is in the form of disk wheels 16, one of which is mounted at each end of the yarn-carrier frame 15, so as to bear upon the stitches as they are castoff the needles. As a convenient means for mounting the wheels 16 I employ a block 17, attached to the end of the yarn-carrier frame by screws or other means, this block being vertically apertered and a bar 18 fitting loosely within such aperture. The lower end of the bar 18 is slotted, and between the two arms thus formed the wheel 16 is journaled. The upper end of the bar 1S is reduced to form a stem 20, which projects above the block 17 and around which is'coiled an expansion-spring 21,whicli reacts between the shoulders formed by reducing the diameter of the bar18 and an apertured screw-plug 22, set into the upper end of the aperture of the block 17, the stem 20 projecting loosely through the aperture of the plug. The spring 21 forces the bar 18 downwardly, and its movement in this direction is limited by means of a stud 19, projecting laterally from the bar through an elongated aperture in the block 17. The tension of the spring 21 may be adjusted by means of the plug 22, and the function of the spring is to hold the wheel 16 yieldingly against the fabric.

The carrier 15 is adapted to reciprocate upon the rails 13, and the rearward depressor only in each direction of movement is in service and performs the function' of forcing the stitches downwardly upon the loops held on the needles.

I claim as my invention- 1. Ina knitting-machine, in combination,

.a yarn-carrier frame, and a spring-depressed disk wheel carried thereby for depressing the fabric as formed.

2. In a knitting-machine, in combination, a yarn-carrier frame, a bar loosely carried by and projecting downwardly from such frame,

a spring for yieldingly holding the bar in its
