IVILLIAM PEARSON, OF SALT LAKE CITY, U TAH TERRITORY.
THICKENING-THREAD ATTACHMENT FOR KNITTING-MACHINES.
SPECIFICATION forming part of Letters Patent No. 462,155, dated October 27, 1891.
Application filed April 29, 1891.
To all whom it may concern:
Be it known that'I, WILLIAM PEARSON, of Salt Lake City, in the county of Salt Lake and Territory of Utah, have invented a new and Improved 'ihickening-Thread Attach mentfor Knitting-Machines, of which the following is a full, clear, and exact description.
The invention relates to knitting-machines for knitting hosiery; and its object is to providea new and improved attachment for knitting-machines, whereby the hosiery can be produced with double heels, double toes, and double knees.
The invention consists of certain parts and details and combinations of the same, as will be described hereinafter, and then pointed out in the claims.
Reference is to be had to the accompanying drawings, forming apart of this specification, in which similar letters of reference indicate corresponding parts in all the figures.
Figure 1 is a side elevation of the improve ment as applied, with parts in section. Fig. 2 is a front view of the same. Fig. 3 is a top view of the cam in place on the table. Fig. 4 is a perspective view of the cam, and Fig. 5 is a side elevation of the fabric.
The improved attachment is applied on a knitting-machine of any improved construction provided with the usual table A and the carrier B, supporting the thread-guide C for feeding the thread to the needles D. An auxiliary thread-guide E is employed, which is made U-shaped, as is plainly shown in Fig. 1, and serves to feed a second thread to the needies D during part of the revolution of the carrier B. The thread-guide E is formed on an angular arm F, pivoted at F to a frame G, mounted to slide vertically in a bearing H, secured to the carrier B next to the ordinary thread-guide O. The lower end of the frame G is adapted to travel on the top of a circular cam I, set in a corresponding groove g in the table A and fastened in place by screws J ,passing into the sideof the tableAagainst the outer face of the circular cam I. By loosening the screws J the cam I may be turned on the table, so that the cam acts on the frame G Wherever desired. The lower end of the bearing H is slotted for the passage of the cam I, and in the bearing H a spring K is placed, pressing on the frame G, so as to hold the latter Serial No. 390,918- No model.)
in contact with the top of the cam I. One half of the cam I is considerably lower than theother half, so that the frame G is raised during one half-revolution of the carrier 13, whereby the thread-guide E is thrown above the needles D, thus preventing the feed of the auxiliary thread to the said needles. During the other half-revolution of the carrier B the frame G, and consequently the thread-guide E, is in the lower position, so that the auxiliary thread is fed to the needles and a double webbing is formed.
From the bearing H extends outward an arm L, supporting the spool N, from which the auxiliary thread passes over a guide 0 to the eye of the thread-guide E. The guide 0 is supported on a rod P, fastened to the frame G. A spring Q is secured to the frame G and passes under the joint of the arm F at the pivot F, so as to lock the said arm in the position for feeding the thread to the needles, or when it is not desired to use the auxiliary thread for forming a double webbing then the said arm F is swung into a position shown in dotted lines in Fig. l, in which position it is held by the action of the spring Q on the pivoted end of the arm F.
It is understood that when the machine is in motion the thread is fed to the needles D in the usual manner by the thread-guide C. Now when it is desired to form a double heel or toe the operator throws the arm F into the position shown in full lines in Fig. 1, so that an auxiliary thread is fed to the needles D during part of the revolution of the carrier, so that a double webbing is formed on part of the fabric. When it is desired to discontinue the double webbing, the operator throws the arm backwardinto the position shown in dotted lines until such time as another double webbing is to be formed, say, for the heel or toe, when the said arm is swung back to its normal position.
In order to form double Webbing for the knee on the front of the hosiery, as shown in Fig. 5, the cam I is turned on the table A to bring the lowermost part of the cam into the proper position with relation to the front part of the hosiery. \Vhen the double webbing for the knee has been formed and it is desired to form the double heel or toe parts, the operator turns the cam I around on the table A, so that the lowermost part of the cam I is at the rear of the hosiery, and the double Webbing is thus formed on the heel, sole, and toe of the hosiery.
Havingthus described my invention, what I claim as new, and desire to secure by Letters Patent, is
1. lhe combination, with the knitting-inachine table and carrier, of the circular cam resting upon the table and adjustable thereon around the carrier,.means for securing the cam in its adjusted position, a vertically-sliding frame or bracket alongside of the carrier resting at its lower end on the upper edge of the cam, and an auxiliary thread-guide carried by the bracket or frame, whereby by ad- 'justiug the cam the auxiliary thread may be incorporated in different parts of the fabric to re-enforce the same, substantially as set forth.
2. The combination, with the table having an annular groove, set-screws intersecting the same, and the carrier, of the'circular cam resting in the groove and adjustable therein around the carrier when released by the setscrews, and the verticallysliding springpressed frame resting at its lower end on the cam and having a swinging thread-guide pivoted on its upper end, substantially as set forth.
3. An attachment for knitting-machines, comprising the outward-bowed frame G, having a vertically-extending lower end, a bearing H therefor, a spring on the frame Within the bearing,a cireularcam on Which the lower end of the frame rests, an angle-arm F, pivoted to the upper horizontally-extending por- W ILLIAM PEARSON.
