THREAD CLEANER FOR TEXTILE MACHINES.

Application filed February 7, 1924.

" being'had therein to the accompanying drawing.

This invention comprises a thread cleaner for textile machines.

It is contemplated among the objects of the invention, to provide a device of this character which may be readily attached to and detached from a portion of a textile machine, which will take up a very small space and have few parts, so arranged as to be practically fool proof.

It is another object to provide a cleaner having a fixed blade and a movable blade associated therewith, the mechanism for moving the movable blade being simplified and standardized so that it can be readily manufactured and assembled and locked in adjusted position.

Still a further object is to provide means for carrying a guide, associated with the cleaner, the arrangement being such that it may be readily attached and detached, and provision is also made for porcelain or friction reducing portions where the thread might come in contact with the device.

Other objects and advantages will in part be apparent and in part be brought out more fully in the description whichfollows:

An embodiment of the invention is illus trated in the accompanying drawings, the following views being shown:

Figure 1, is a view in front elevation of a cleaner embodying my invention;

Fig. 2, is a bottom view of the same;

Fig. 3, is a view in vertical section on line 33 of Fig. 1;

Fig. 1, is a fragmentary view in rear elevation of the back portion of the device shown in Fig. 1;

Fig. 5, is a fragmentary detail view, partly in section illustrating a means for mounting the blade moving instrumentality.

In these views, 1 designates a body or support provided with means for attaching it to a textile machine or the like, here shown as screw receiving openings 2.

Upon the body there are carried two sets of spaced-apart blade supporting arms 3, 3, and 4:, 4;. These may be formed as a part of Serial No. 691,145.

the support 1, and extend therefrom in spaced-apart relation. Between the arms 33, there is disposed a fixed blade 5, suitably secured to the arms as by rivets or the like 6. This blade has a curved lower por tion 7, and it rests, upon its upper surface, on a portion of the support 1 disposed between and connecting the sets of arms, this portion acting as a support for the fixed blade and a bearing upon which a movable blade can slide.

Between the arms 4, at, there is disposed a movable blade 8. This has a curved lower portion 9} and an edge extending downwardly to cooperate with a corresponding edge of the blade 5, and act as a cleaner. An edge of the movable blade bears upon a por tion of the support 1, and means are pro vided for moving the blade with relation to the fixed blade 5.

As here shown there is a cut out portion or slot 10, in the inside of each arm 4, extending from the open end of the arms, downwardly therebetween. Into this slot there is adapted to fit a ii'anged portion 11 of an adjusting screw 12. The screw has a threaded portion extending into a threaded opening on the movableblade, and a knurled thumb nut 13, carried on a portion extending outwardly between the arms. A keeper 1% fits between the arms filling the space above the adjusting screw and maintaining it in place. The keeper may be suitably secured as by a rivet 15.

Means are provided for locking the 1novable blade in adjusted position, and as here shown there is provided a set screw 16, threaded into an opening in one of the arms 4 and adapted to engage a surface of the movable blade. This set screw is hollowed out for the reception of a wrench and is so placed as not to project beyond the surface of the arm when set.

Means are also provided for carrying a threaded guide, and as here shown an opening is formed in the lower portion of arms 4, into which a wire or the like 17 is adapted to pass. This is secured adjustably therein as by a set screw 18 best seen in Figs. 1 and 4. The wire is extended upwardly and thence into alignment with the opening between the blades where it is provided with the usual porcelain or like guide 19, here shown in the form of the well known pig tail.

The portion of the arms which might come in contact with the thread are vpreferably surfaced with afriction minimizing agent such as porcelain or the like, indicated by numeral 20 in Fig. 2. As another precaution against Wear and cutting of the thread,

a bar 21 is disposed in openings carried by oppositely disposed arms and extends between the blades at a point above the bottom of the slot formed by the blades. This bar is preferably formed of hardened steel or the like and rounded .to minimize friction. iIt ismaintained in position by-a plug of shellac orltherlike cementitious material indicatechat 22. To remove tll 'bar, it is merely necessary to ,melt the shellac .When it :may be slipped from ,the openings.

From the foregoing it will be apparent parts are contemplated ;as within the scope of a the inventi on as {set forth in the claims.
