MACHINE FOR UNITING KNITTED GOODS.
No. 415,779. Patented Nov. 26, 1889..
UNITED STATES PATENT 'OFEIcE.
JOHN XV. HART AND SYLVESTER B. XVILKINS, OF ROCKFORD, ILLINOIS, AS- SIGNORS TO THE S. B. \VILKINS COMPANY, OF SAME PLACE.
MACHINE FOR UNITING KNITTED GOODS.
SPECIFICATION forming part of Letters Patent No. 415,779, dated November 26, 1889.
Application filed April 12, 1889- Serial No. 307,071 (No model.)
To all whom it may concern:
Be it known that we, JOHN W. HART and $YLVESTER B. TVILKIN S, residing at Rockford,
1n the county of Vinnebago and State of Illi- 5 nois, and citizens of the United States, have invented a new and useful Improvement, in
Machines for Sewing Knit Fabrics, of which the following is a specification, reference be ing had to the accompanying drawings, in
IQ which I Figure 1 is a vertical section taken at line 1 of Fig. 2, looking to the left, showing only such parts of the machine asare necessary to illustrate our invention.
T5 section at line 2 of Fig. 1, showing only such parts as are necessary to illustrate our inven tion.
It is common to close seams in knit goods as, for example, the toe of a stocking by 2o placing the stitches on both sides of the seam to be closed onto points or pins arranged in a sewing-machine adapted to do the work. To
do this work, it is common to use machines having rotating cylinders, and also machines 25, in which the part which receives the work is straight instead of curved. Usually the part which receives the work has been a fixed part of the machine. \Ve are aware that removable sections to receive the work have been used in a machine having arotating cylinder.
Our invention relates to that class of machines designed for closing the seams in knit goods in which the work moves in a straight line; and the object of our invention is to 3 5 provide such a machine with removable sections adapted to receive the work and to be moved along in the machine, and with novel mechanism for moving such sections through the machine, which we accomplish as illustrated in the drawings andhereinafter de scribed. That which we claim as new willbe pointed out in the claims.
In the drawings, A B represent the supports or standards connected with the base of a sewing-machine adapted to do the suggested Work. C is a casting which may be cast with the supports A B.
a is, in fact, a part of the casting O. In the top of the casting C there is a groove adapted Fig. 2 is a vertical to receive a removable section. D, which sec- 7 tion has a downward extension 1), adapted to enter such groove. The removable sectionD is provided with a number of seamer-points c, which are held between the two flanges d e on the section by means of a plate f. The downward extension I) on the section is provided on its under side with a series of teeth g, which form a rack.
E F are two gear-wheels suitably supported and arranged to engage with the rack g'upon the under side of a section D.
G is a shaft suitably supported, on which there is a pinion h, which is arranged to e11- gage with both of the wheels E F.
H is a ratchet-wheel, which is driven by a pawl in any suitable known manner. This pawl and the parts which operate it are not shown-in the drawings.
2' are guides secured to the part 0, which guides pass over the groove in such part 0 and are designed to prevent the sections D from being raised up by the act-ion of the wheels E F.
In the edge of the flange d there are notches 7 5 between the seamer-points.
WVe have not shown the needle-arm or any other operative parts of the machine,because they are no part of our invention, and are not necessary for the purpose of illustrating our improvement.
The removable sections and the seamerpoints are to be so arranged relative to the needle that when the needle descends it will pass down close to the front of one of the seamer-points or between two adjoining seamer-points, as the case may be.
I11 use a number of the detachable sections D are to be provided, and the stitches of the work the seam of which is to be closed are to be placed upon one of the sections, as many operators being employed for this purpose as may be necessary. The operator of the machine is to place the sections one after an other with the work thereon in the groove in 5 m the part 0, and such sections will be carried forward intermittently by the movement of the pinion h and wheels E F, and the needle being at the same time in motion the seam will be closed. 10o
The machine, as shown, is intended to be so constructed that the needle descends first just in front of one of the seamer-points and at the next stroke between two adjoining seamer-points.
In the drawings we have shown two removable sections D, except that in one only a portion of the seamer-points are shown and in the other none of such points are shown. lVe thus have provided devices by means of which straight removable sections can be moved through a sewing-machine, the seamerpoints carrying the Work being brought one after another in line with the needle.
What we claim as new, and desire to secure by Letters Patent, is as follows: a
1. In a machine for closing the seams in knit goods, the combination of a stationary support 0, having a straight groove, one or more removable sections D, each having seamer-points c and an extension I) entering the groove and provided with rack-teeth, guides 2', arranged on the support and extending over the section or sections to retain the same in engagement with the groove, and rotating gear-Wheels engaging the rack-teeth of some of the sections and by their rotation moving the sections in the groove of the support, substantially as described.
2. In a machine for closing the seams in knit goods, the combination of a support having a straight groove, the removable straight sections,'each having seamer-points and an extension entering the groove and provided with rack-teeth, two rotating gear-wheels engaging the rack-teeth of some of the sect-ions and by their rotation moving the sections in the same direction in the groove of the sup port, and a drive-shaft having a ratchet-wheel and provided with a pinion interposed between and operating both gear-wheels, substantially as described.
