THREAD GUIDE AND CLEANER.

SPECIFICATION formingpart of Letters Patent No. 718,617, dated January 20, 1903.

Application filed January 20, 1902. Serial No. 90,574. (No model) If? ctZZ whom, it may concern:

Be it known that I, FRANK E. GARNER, a citizen of the United States of America, residing at Long Meadow, in the county of Hampden and State of Massachusetts, have invented new and useful Improvements in Thread Guides and Cleaners, of which the following is a specification.

This invention relates to thread guides and cleaners and is in the nature of an improvement on my prior patent of the United States, dated July 23, 1901, and numbered 679,121. In my said patent it has been found inconvenient in practice to adjust the edge of the blade relative to the abutment against which it is drawn by an imperfection of the yarn tothat degree of nicety which is essential in certain classes of work to which the guide is ap plied; and the object of this invention lies in the provision of means whereby this defect is overcome. Furthermore,in my said prior patent it has been found in practice that the spring-blade will sometimes buckle when used on heavy yarns, owing to the fact that it is requisite to the proper function of said blade that it should be made quite pliable. A further object of this invention is to overcome this defect. Again, in the construction em.- bodied in my said prior patent it is possible for an operative to insert the point of scissors or some similar tool between the abutment and the edge of the blade and spring the latter away from the abutment, whereby imperfections on the yarn will pass through the cleaner; and a still further object of this invention is to prevent any such tampering with the guide once the blade has been adjusted at the proper distance from the surface of the abutment.

In the drawings forming part of this application, Figure 1 is a plan view of a thread guide and cleaner, illustrating my invention. Fig. 2 is a sectional elevation through a portion of the guide, taken on line 2 2, Fig. 1. Fig. 3 is a perspective view of the guide.

In carrying my invention into effect I cast over which may be sprung a guide-wire c.

This is preferably made by forming the two ends of a piece of wire into loops f, which may be forced down over said ears, the middle portion of the wire being upwardly and backwardly bent in the shape of a V, as shown, thereby forming two other loops g, through which the yarn 0 runs and by which it is supported in a fixed position relative to the abutment 1) and whereby the yarn in its movement through the guide will draw across the said vertical face of the abutment.

Instead of the blade shown and described in my said prior patent as being made of spring-steel I provide herein a rigid blade 77., pivotally supported on a post 2', forming part of or secured to the base a and swinging freely on said post. The free end of this blade 71 is beveled'ofi to an edge, as shown clearly in Fig. 1, and it may swing against and away from the said vertical face of the abutment b. Mounted on the same post 2', preferably, is a spring-holding clip In, in which the spring Z is secured, the tendency of which is to'normally hold the edge of the blade 77. away from the face of the abutment b. The means provided herein for immovably holding the clip and its spring in the desired position on the post Z consist of two nuts m, between which the clip is locked in such manner as to leave the blade it free to swing loosely on the post '6. While this is a convenient and cheap construction, some other, equally good, may be adopted whereby the function of the parts may be attained.

Secured to the base a. on the side of the blade opposite that against which the spring Z bears there is a stop (indicated by n) for limiting the movement of the blade it away from the abutment b. This stop n is adjustable toward and from the blade by means of a bolt 0, which passes through a slot therein. Preferably this stop is mounted to slide between the ribs cast on the base, as shown in the drawings, and the spring Z always holds the blade yieldingly against the stop.

From the above description it is apparent that by means of the construction provided herein a thread guide and cleaner having all of the characteristics of the construction forming the subject of my said prior patent and all of the delicacy of action is yet infinitely stronger and possesses, besides, the

capability of being adjusted by gage, also the further advantage of being unchangeable in its relation to the face of the abutment against which it is drawn by an imperfection in the yarn.

Normally the blade is held away from the thread in its course across the face of the abutment and in contact with the stop it. The sharp edge of the blade lies in close proximity to the line of yarn, and any imperfec tion in that yarn sufficient to engage the edge of said blade will draw the latter against the abutment, where the imperfection will either be shaved oif or the thread will be cut by being pinched between the edge of said blade and the face of the abutment, the said blade, as in my said prior patent, occupying a position which is inclined against the direction of movement of the yarn.

In order to set this thread-guide to any desired size of yarn, it is only necessary to provide a thin sheet-metal gage, which may be slipped down in contact with the vertical face of the abutment b, when the nuts on the bolt 0 may be loosened and the stop it be moved into contact with the side of the blade, whereupon the nut on the bolt 0 is again tightened and the gage withdrawn. It has been found in practice that a very great saving in time results in a device of this character, which may be set by a gage.

Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States, is

1. A thread guide and cleaner comprising a base, an abutment thereon, a thread-guide whereby the thread may draw across the face of said abutment, a rigid blade, one end of which is pivotally supported in a position inclined to the line of movement of the thread whereby the other may swing against and from the face of said abutment, a spring for normally holding the end of said blade away from the abutment, and a stop for limiting the swing of said blade.

2. A thread guide and cleaner comprising a base, an abutment thereon, means for guiding the thread across the face of said abutment, a cleaning-blade pivotally supported on said base in a position inclined to the line of movement of the thread, an adjustable stop for limiting the swing of the free end of the FRANK E. GARNER.
