SPINNING-FRAME.

Specification of Letters Patent.

Patented Dec. 28,

Original application filed. March 15, 1915, Serial H0. 14,357. Bivided and this application filed Setober 15,

To all whom it may concern Be it known that I, ALBERT H. Monro), a citizen of the United States, residing at Lowell, in the county of Middlesex and State of Massachusetts, have invented certain new and useful improvements in SpinningFrames; and I do hereby declare the following to be a full, clear, and exact de scription of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to improvements in spinning frames.

The object of the invention is to improve the construction of the thread guide, thread board, do'lling rail and associated parts, and to this end, the invention consists in the improvements hereinafter described and particularly pointed out in the claims.

In the accompanying drawings illustrating the invention Figure 1 is a plan of the dotting rail of the spinning frame showing the thread board attached thereto and showing their relative position to the roll bosses of the drawing rolls; Fig. 2 is a plan of one of the thread boards shown in Fig. 1; and Fig. 3 is a longitudinal sectional elevation of the same on the line 33 Fig. 2.

The thread guide, which is of the kind known as a vibrating thread guide, not because it vibrates but because the thread vibrates in it, has a D-shaped guide passage, the long straight side of which affords ample surface for wear, thereby preventing grooving of the guide.

The thread guide 20 is supported on the thread board 21 in such. wise as to be adjustable for the purpose of bringing the straight side of the D-shaped thread passage into position normal to the direction of the line of the thread running from the drawing rolls 13 to the guides, and this is secured by providing the thread guide with a shank 22 curved so that when it is adjusted it turns the guide about a center which is the center of the spindle to which the guide delivers its thread. Thus, referring to 1, it will be observed that the spindle 23 is the center of curvature of the shank 22 of the thread guide 20, and that the thread guide 20, when the clamp is loosened, may be turned about such spindle center. The under side of the front end of the thread board 21 is grooved to receive Serial No. 56,121.

the curved shank 22 of the thread guide, and a clamp 2st, having a correspondingly shaped groove is provided for securing the thread guide in adjusted position. The clamp Qi is third class lever, having its fulcrun at 25 being secured in place by means of the screw :26. The curvature of the shank of the thread guide prevents any tipping of the thread guide with respect to the thread board.

The thread board support 80 is secured to the under side of the dofling rail 31 at points corresponding to the positions of the spindles. l bolt is employed for this purpose. The thread board support 30 is slotted at 33 to receive the bolt 32 and to permit adjustment longitudinally so as to bring the thread guide in proper position with respect to the spindle.

The features of advantage of this con struction will be apparent to those skilled in the art. In the first place, the locations of the thread boards correspond to the spindle locations, and are, therefore, equally spaced throughout the length of the frame, conducing to convenience of manufacture. In the second place, accidental variations between the positions of the thread boards and the spindles, owing to any inaccuracy of n'ianufacture, may be compensated for by the two adjustments provided for the thread guide, the one, the longitudinal adjustment provided by slotting the thread board support, and the other, the thread guide ad justment provided by the means for permitting the thread guide to be turned so as to present its straight side normal to the direction of the thread. Again, the worn thread eyes may be replaced with the utmost ease, and when replaced, adjusted with the utmost facility, to correct position. Furthermore, in case of any incorrectness of position of the center of the thread guide with relation to the spindle center, the thread guide, thread board, and thread board support, may all be swung together laterally, so as to correct the position of the thread guide with relation to the spindle. It will thus be seen that this construction lends itself to other spacing on the dothng rail than that shown.

Having thus described my invention, what is claimed is 1. A spinning frame having, in combination, drawing rolls, spindles, a dofling rail, a thread board, a thread guide having an areuate shank mounted on the thread board and a clamp for engaging the arouate shank for permitting adjustment of the thread guide.

2. A spinning frame having, in combination, drawing rolls, spindles, a dotting; rail,

a thread board supported on the dotting rail a thread guide having a straight thread-engaging surface and an areuate shank supported by the thread board and a clamp for engaging the shank of the thread guide to permit the straight threadengaging surface thereof to be engaged perpendieularly to the line of the thread from the rolls to the spindles 3. A spinning frame having, in combination, drawing rolls spindles, a doiling rail, a thread board supported on the dotting rail, a thread guide having a straight threadengag'ing surface supported by the thread board, and means for adjusting the thread guide on the thread board wh reby the straight thread engaging surface of the thread guide is positioned perpendicular to the line of the thread leading from the rolls to the spindle.
