Application filed FebrriarylO, 1917. Serial 130.147,?76.

To all whom it may concern: I

Be 1t known that I, JosEPrrBnN'NnT'r, a

citizen of the United States, residing in the? city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Tension Device for Hosiery-'Knitting" Machines, of which the following isaspecification.

My invention consists of an attachment for a knitting machine embodying a plate formed with eyes, and a series of tension springs having eyes therein adapted to register with those of saidplate so that different numbers or ends of threads or yarn may be guided through the eyes of said plate and said springs, and subjected to the tension of the latter as they are directed to proper of stockings or hosiery'by the use of two or more threads according to the nature of the stockings.

The invention is satisfactorily illustrated in the accompanying drawing, but the important instrumentalities thereof may be varied, and so it is to be understood that the invention is not limited to the specific details shown and described.

Figure 1 represents a top or plan view of a portion of a hosiery knitting machine embodying my invention.

Fig. 2 represents a partial side elevation and a partial vertical section thereof on the line 22 of Fig. 1.

Fig. 3 represents a horizontal section of the tension springs employed on the line 33 Fig. 2.

Fig. 4 represents a side elevation of said springs and the support device therefor at a right angle to Fig. 2.

Similar numerals of reference indicate corresponding parts in the figures.

Referring to the drawings.

1 designates a carrier ring of a hosiery knitting machine, 2 a frame which supports said ring, 8 yarn carrying fingers which are pivotally mounted on said frame, 4; an angular bracket which rises from said frame, and 5 an eye plate which is supported on said bracket, 6 an oscillating weight, 7 a plate in the base of said ring 1 forming the bed for said weight, and 8 a shear, said. plate 7 forming the bed member of said Specification of Letters Patent.

shear, the axes of'said shear and weight be- 'ing'on said plate 7, and the latter belngs'ustained by the elbow 9 which'latter is secured to the limbs 10 of the'frame 2 of the Carrier ring 1. The weight 6 and shear 8 are pivotally connected with theswingin g lever 11 which is mounted on said limb 10, the members thus far described being well known in the art.

Depending from the eye plate 5 by the arms 12 are the tension springs 13 each of which in the present case is formed of two plates 14, placed side by side, in the lengths of which near their lower terminals are portions bent or turned respectively to the right and left forming the eyes 15 which.latter are below the plate 5, so as to register With the eyes 16 in the latter, it being noticed that said eyes 16 and 15 are four in number so that they are serviceable for four: threads say in the knitting of check stockings, one thread for the welt one thread for the leg, one thread for the ankle, and one heavy thread for the heel and toe, but when it is desired to use but two threads, one thin thread for the body of a stocking, and one thick or heavy thread for the heel and toe, only two eyes in the plate 5, and two eyes 15 in the springs 13 will be in service.

It will be seen that while the threads are freely running to the needles, they play from the plate 5 freely through the eyes 15 of the springs, but when a thread or yarn is to become idle, another finger drops and starts feeding a difl'erent thread for two or three needles before the first finger raises and carries the thread clear of the needles, making it an idle thread.

This thread still held by the last needles into which it is fed, and which are traveling in a rotary motion, is drawn by the needles, through the finger in its new position, which brings it through the tight or closed part of the spring, thereby putting suflicient tension or drag on the thread to make its entrance under the loose weight, and positively between the shears.

The thread now being under the weight and between the shears, which are opened automatically, is cut, and held there until such a time as it may be needed again.

The other threads, however, when not side by side idle are not subjected to tension of the springs 13, in which case the eyes'15 serve only as guides for said threads.

Having thus described my invention What I claim as new and desire to secure by Let ters Patent, is z 1. A thread-tension spring for hosiery knitting machines formed of plates, said spring being provided intermediate its ends With eyes turned out from said plates,

spring serving both as a tension device and guide.

2. A thread-tension spring for hosiery knittingmachines formed of plates placed iIl-0PpOSlt6 directions forming eyes, and

Copies ot this patent may be obtained for said and havingintermediatetheir ends portions turned outwardly therefrom means securing said plates together, saidspring serving both as a tension device and guide.

3. A thread-tension spring for hosiery knitting machines, the same composed of plates having intermediate their ends oppositely outturned portions forming eyes, the adjacent faces of the plates upon opposite sides of said eyes being in close contact with each other, and means of said plates together, said spring serving both as a tension device and guide.
