To all whom it may. concern r Be it known that we, FRANK B. WILD A the United States and a subject of the King g or Great Britain, respectii ely, residing at Norristown Fenns lvania have invented certain new and useful Improvements in Thread-Guides, of which. the following is av specification.

.Qur invention is designed to "provide simple form of 'thread guide which :will feed the' thread with accuracy and'certamty andone which is susceptible oi'adiustnient to suit the various conditions in use. The-invention consists-in the features and 1 combinationand arrangement of parts hereinafter described and particularly pointed out in the claims. I

This arm is slotted at 4: and receives a screw 5 by which the arm. isheld to the post 6 fiazed to the horizontal. needle guard slate 7. This '"needles and, as shown in the drawings, the yarn from the guide eye passes down at an inclination and across the inner edge oi" the guard plate and into contact with the cyl-- inder needles in position to be taken hy the needle' hooksfl' Our and'guard will meet all conditions and character of Work.

' Our invention permits the adjustment of the guide eye and the needle guard, i. e., the plate 7 to be independently performed. That is, the guide eye may be maintained in one position while the guard plate may be adjusted, and conversely the guide eye can be set in difierent positions without adjusting the needle guard plate. Further, our guide presents, as above referred to, a free space between the where the needles take the thread offering no interference to the passage '95 knots or lumps between the guide eye an the needles, and thus the liability to rupture of the yarn is removed. Furthermore, the form of yarn carrier in general use has the disadvantage of contacting with the hooks 'of the cylinder needles, which wears and destroys the hooks long before theneedle is otherwise worn out. This disadvantage is not present in our construction. The dial needles, in practice being fed by the cylinder needles, lie at a relatively greater distance from the guard than the cylinder needles.

. The guard plate may be and is formed asshown in machines of the coarser gages we may construct it as shown in the other figures, wherein at its corner most distance from the guide eye it is provided with a guide 8' for the thread, consisting in the particular construction chosen to illustrate our invention of a projection extending up from the plate t. Preferably this projection is formed inte-.

preferably gral with the plate, simply being turned up :as indicated. The position of this projection and the edge of the plate 7 relative to the needles, is such that the thread is controlled up to the pointwhere cylinder needles "takes it, this being approximately at the point X. The dial needles work under the plate 7 while the cylinder needles work vertically at the .inner edge of the plate, as shown in Fig. 1.

\Ve claim:

1. In combination, a needle guard plate horizontally disposed at right angles to the fed needles and adjustably mounted to be set in different positions circumferentially of the needle row and toward and from the same, and a'guide eye adjustably mounted on and stantially as described.

2; In combination a needle guard plate horizontally disposed and adjustable toward and from the needle row and adjustable asto angular position in respect to the. needles and a guide eye located above the surface ofthe needle guard plate, and supported by said needle guard plate adjustably, said guard plate having a free space between its needle guide eye and the point Figs. 4: and 5, but for.

the corner of the plate locii't'ed above the guard plate, subacross said inner edge to the needles.

3. In combination, a needle guard plate, a post supporting the same and rotatably mounted, said post having a connection with the needle guard plate eccentric to its axis to shift the plate along the needle row, said guard plate being adjustable in rela tion to the post toward and from the nee dles, and a guide eveadjustably mounted on and above the needle guard plate, substantially as described. a

4:. In combination, a horizontal needle guard plate,.a rotatable post having a screw and slot. connection with the needle guard plate eccentrically arranged in relation to --the axis of the post, and a guide eye supsubstantially as de-- consisting of a horizontal needle guard plate adjustably mounted to'be set in proper relation to the needles and having an upwardly extending projection at one corner, an arm having a guide eye, a post extending up from the horizontal needle guard plate and upon which the arm is supported, and an adjustable connection between said arm and post, substantially as described, said guide eye being at the opposite side of the said horizontal needle guard plate from that upon which the projection is located.

7. In combination a needle guard plate disposed horizontally and adjustable toward and from the needle row, and adjustable also into different positions circumferentially in respect thereto, and a yarn guide eye mounted on the needle guard plate and adjustable toward and from the needle row and circumferentially in respect to the same and independently of the adjustment of the ,needle guard plate, substantially as described.

In testimony whereof, we affix our sigma tures in presence of two witnesses,

FRANK ,BJWILDMAN. GEORGE LAWSON BALLABD.
