SlNKER-BAR FOR STRAIGHT-KNITTING MACHINES.

SPECIFICATION forming part of Letters Patent No. 403,985, dated May 28, 1889.

Application led September 17, 1888. Serial No. 285,562. (No model.)

To a/ZZ whom t may concern:

Beit known that I, FRANK. E. BUsIEL, of Laconia, in the county of Belknap and State of New Hampshire, have invented a new and useful Improvement in Sinker-Bars for Straight-Knitting Machines, of which the following, taken in connection with the accompanying drawings, is a speciiication.

The object of my present invention is to secure the sinkers of astraight-way knittingmachine rmly in xed positions without the use of solder or other permanent fastening, so that when a sinker becomes worn or broken it may readily be removed and replaced by a new one, and this is accomplished by a novel device which will be more readily understood by reference to the description of the drawings and tothe claim to be hereinafter given.

Of the drawings, Figure l represents a front elevation of a portion of a sinker-bar having a series of sinkers secured therein according to my invention. Fig. 2 represents Fig. 3 represents a sectional elevation of the same, the cutting-plane being on line o@ on Fig. l; and Fig. 4: represents an elevation of a sinker.

In the drawings, Aisa sinker-bar, the front side ofwhich is provided with a series of vertical grooves, a a, in which are mounted the sinkers b b. The front side of said sinker-bar A is also provided with a dovetailed groove extending the entire length thereof and of such a depth as to extend beyond the front edges of said sinkers b b, each of which is provided with a dovetailed notch, c, as shown in Fig. 4, so that when the locking-bar B is inserted into said dovetailed groove it will enter the notches o c in the sinkers h b and secure them irmly in position, so that they m ay not be moved either endwise or in the direction of their widths.

Bars have heretofore been in use which engage with notches in the edges of the sinkers, but said bars have been arranged in bearings independent of the sinker-bar and movable vertically to adjust the sinkers, or have been provided with a cam-groove and were reciprocated in their bearings to successively move the sinkers vertically, and in either case said bar would vnot of itself prevent the transverse movement of the sinkers; but in my improved device, by virtue of the dovetailed longitudinal groove formed in the sinker-bar, the locking-bar B prevents either an endwise or a transverse movement of said sinkers and secures them in fixed positions without the aid of additional fastenings.

It is obvious that by withdrawing or partially withdrawing the bar B from the groove in which it is mounted any or all of said sinkers may be removed and replaced by new ones whenever it becomes necessary to do so.

What I claim as new, and desire to secure by Letters Patent of the United Stat-es, is-

In a knitting-machine, the combination of a sinker-bar provided witha series of vertical grooves and a longitudinal dovetailed groove cut in its front side, with a series of sinkers mounted in said vertical grooves and provided each with a dovetailed notch in its front edge, and a dovetailed locking-bar Iitted to and movable endwise in the longitudinal groove of said sinker-bar and in the notches in said sinkers to rmly hold them in position and prevent any movement eudwise or transversely thereof.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

FRANK. E. BUSIEL.
