6' Claims. (01. 242-149 In the process of hand knitting, crocheting and the like, a considerable portion of the skill which is requisite to a satisfactory product is involved in maintaining a uniform tension ,of the yarn or worsted in order to give uniformity of texture of the product. The ability to maintain this uniformity of tension is only acquired by long practice, and even thenis only maintained by close attention to the work in hand. Also, the use of the fingers in maintaining the tension of the yarn has atendency to tire the hand, limiting the period of effective work and close attention to the texture of the product, resulting in eye strain, particularly when the work is fine.

In order to enable those'lacking in practice and the high degree of skill ordinarily required to produce satisfactory work, and even with skilled workers to avoid the weariness incident to regulating the tension by hand, I have provided an automatic tension device for use in hand knitting which maintains automatically a uniform tension and hence uniformity of texture, without the necessity for any exercise of skill or any close attention to the texture of the product.

The device consists of a simple, easily adjusted automatic tension which is preferably combined with a yarn guide in suitable relation thereto,

the tension device and yarn guide being in ac-.

cordance with the preferred practice mounted on a support for attachment to the hand, the whole being so simply devised and capable of such cheap construction that it is adapted for distribution at a low price, and for manufacture cheaply in large quantities.

In the accompanying drawing I have illustrated a hand tension device embodying the features of my invention in the preferred form.

In the drawing: v

Figure 1 is a perspective View of the tension device attached to the hand in operative position and showing a convenient manner of feeding yarn, worsted or thread therefrom to the work.

Figure 2 is a side viewof the same.

Figure 3 is a view looking upwardly at the device as seen in Figure 2 and slightly distorted for convenience of illustration. v

Figure 4 is a view looking downwardly at the device as seen in Figure 2. V

Figure 5 is a section on the line 5, 5 in Figure 4, looking in the direction of the arrows.

Referring to the drawing by numerals, each of which is used to indicate the same or similar parts in the different figures, the construction shown comprises a tension means shown in the form of members or plates] and 2, and spring I,

a yarn guide 3 and a support of any suitable'construction shown in the form of a base plate 4. This support may be held in any preferred manner. As shown in Figure 1 it is securedto the fourth or little finger of the hand at 5 by means 5 of a spring ring 6 shown as but not necessarily formed integral with the body member or base plate 4. r

The tension members I and 2 are held in operative relation to each other and to the work by 10 the spring I which is shown in the form of a fork. This, in-the form of the invention shown, consists of a spring wire formed into a coil 8, and two parallel arms 9 which are crossed at N] adjacent the coil and extend forwardly there 5 from in converging relation, being turned at right angles to the arm 9 near their ends'at II,- II, said ends bearing on the tension members or plates l and 2 on their respective outside surfaces. Y V 20 More specifically described as to the preferred form shown, the spring ring 6 which secures the support or base plate 4 to the finger consists-of two strips of sheet metal, one indicated by reference'character l2 being the end of the base 25 plate 4 and the other indicated by reference character l4 beingcut from the base plate, leaving a slot l5 which extends oppositely vto said end. The strips 12 and l4 are bent toward each other .on substantially circular arcs, being in the form 30- of the invention shown though not essentially spaced at their ends at l6 so as to substantially enclose the finger and being adapted to be bent at will to fit the wearer;

The tension member 2 as shown consists of a 35 small rectangular plate shown as integral with the support or base plate 4. This tension member ,orplate 2 is bent up at an angle to the base plate which in the form shown is about sixty degrees, see Figure 5, though this. angle may be 40 variedto suit the manufacturen'or it may be changed by bending the plate to suit the user. This gtension plate or member 2 as shown is slotted at II at 2 points at its edge adjacent the base plate and preferably in parallelism with the 45 base plate, and the tension member or plate I is provided with projecting tongues or tabs I8 which are turned substantially at right angles to said plate'and passed through the slots "forming a loose connection between the plates. These 50 are maintained in operative relation by the spring fork], being further positioned ,by' the slot and tongue, connection IL-IB, the spring arms 9 being causedlto' straddle the two plates, the respective arms Bjengagingltherespective plates from the outside. In accordance with the pressure arrangement, plates I and 2 are placed in converging relation so that they converge toward the yarn guide 3 as best illustrated in Figure 2, the tension being preferably applied to the yarn by pressing the yarn between the edges of the plates where they come in closest relation to each other at their edges I9.

It may be noted as shown in Figure 2 that the coil 8 of the spring fork I is at the opposite end of the plates from said edges, the fork extending from this opposite edge along the plates toward the tension point or point of pressing the yarn, hereinafter referred to as the compression point I9.

In order to properly space the plates at the end remote from the compression point, I9, one of the plates, in the illustration plate 2, may be provided with a protuberance at 20, see particularly Figure 2, which engages the other plate I, and provides a definite spacing at this point, though the plates are preferably otherwise shaped to thus converge. I

In order to give the desired adjustment ofthe tension, a series of positioning points 2| may be provided on the outside of one of the plates for engagement by the turned up end I I of the spring fork. This turned up end I I is located between any two of the points or protuberances 2|.

In assembling the tension device the plate I is first placed in operative relation to the plate 2 by folding the plate I substantially parallel to plate 2 and passing the tongues I8 through the slots I1. The spring fork I, the arms of which when removed from the plates are relaxed are normally crossed, is then opened by spreading said arms slightly apart and caused to straddle the plates near their edges adjacent the base plate or body member 4 at the end of the plates opposite the guide 3, the turned up ends I0, I of the arms 9, bearing against the outside surface of plates I and 2, the formspring I is pushed to the left as seen in Figures 2 and 3 to the desired adjustment. To increase the tension the spring is advanced to the left, being held in adjusted position by the points 2|, positioning the turned up end II between two of which it is seated.

To thread the device the yarn or worsted is entered between the plates at their outer edges at 22, drawn toward or beyond the centers of the plates and threaded through the guide 3 which is in the form of a hook formed from a strip cut from the edge of the plate but with its end 24 adjacent the plate as shown. This spacing of the end provides for entering the thread, yarn or worsted within the hook so that the latter serves its guiding function. The device having been duly threaded, is placed in the inside of the hand, the ring 6 being engaged with the fourth or with the third finger if desired or it is attached and arranged in any convenient manner, the hook 3 being preferably adjacent the first finger so that the yarn may be drawn upwardly over the first finger, and, if desired, over the thumb, from which point it is fed outwardly to the work, being drawn forwardly as consumed with a predetermined tension which as aforesaid is exerted at the compression edges of the blade I and 2 at I9, being regulated by the position of the spring fork 1 already described.

I have thus described specifically and in detail a hand tension for knitting or crocheting, embodying the features of my invention in the preferred form, the description being specific and in detail in order that the manner of constructing,

applying, operating and using the invention may be clearly understood, however, the specific terms herein are used in a descriptive rather than in a limiting sense, the scope of the invention being defined in the claims.
