Q THREAD-GUIDE.

Specification of Letters Patent.

Patented Dec. 22, 1914.

Application filed September 9, 1913. Serial No. 788,894.

To all whom it may concern:

Be it known that 1, MICHAEL Erasmus RrmisiLL, a citizen of the United States, residing at Henry River, in the county of Burke and State of North Carolina, have invented certain new and useful Improvements in 'lhreadGuides, of which the following is a specification, reference being had therein to the accompanying drawing.

This inventidn provides a member secured in proximity to a guide for thread, yarn, or other material in such manner that it will sustain a great part of the wear of the material running through the eye of the guide and thus relieve the guide of wear. The member may be attached to the guide-board or to the guide itself, and it is so arranged that, when worn in one place, it may be re adjusted to present another surface to the friction of the running material. 'The invention thus furnishes means whereby the wear incident to the running of the material through the eye is to a great extent taken by an easily adjustable and removable part, and thus there is avoided rapid formation of creases in the guide, which usually cause undue pull, much wear, and sometimes breaking of the material.

When read in connection with the description herein, the details of construction and arrangement of parts contemplated by the invention will be apparent from the accompanying drawing, forming part hereof, wherein embodiments of the invention are disclosed, for purposes of illustration.

While the forms of the invention disclosed by the drawing now are considered preferable ones, it is to be understood that they merely are shown as examples of the principles of the invention, that various changes can be made within the limits of the claims without departing from the nature and spirit of the invention, and that it is not the intention to be limited necessarily to the exact forms shown in interpretation of the claims.

Like reference-characters refer to corre sponding parts in the views of the drawing, of which- Figure 1 is a top view illustrative of one form of wear member attached to a guideboard; Fig. 2 is a side view thereof; Fig. 3 is a sectional view thereof; Fig. 4 is a top view of another form; Fig. 5 is a front View thereof, the guide-eye being omitted; Fig. 6 is a top view of still another form; and Fig. 7 is a front view thereof.

Having more particular reference to the drawings, 8 designates a guide-board or other part, on which is carried a guide 9 in a manner commonly practised in the art. The guide shown is of the pigtail type, having a shank 10 and an eye 11.

In Figs. 1, 2, and 3 0f the drawing, a wear member is shown secured to the guideboard. The wear member of this embodiment preferably is made of sheet metal so shaped that it is a substantially flat disk 12 having a depending rounded annular outer wearing surface or periphery 13 and a central circular depression 141 in its top having a flat bottom through which there is a central opening 15. A washer 16, of nearly the same diameter as the depression 141, is seated in that depression, and the washer has an eccentrically-positioned hole 17 in which is disposed a screw 18 or other suitable adjustable fastener for securing the wear member to the guide-board, the fastener passing through the opening 15, which is of sufficient size to allow for the eccentricity of the fastener. The disk 12 is so located on the guide-board that its rounded periphery or wearing-surface 13 extends partly over the eye of the guide, so that ma terial running through the guide will bear against that surface and not against the portion of the eye contiguous to the guideboard as ordinarily is the case. The desired degree of extension of the wearing-surface of the member may be attained by turning that member and the washer 15 on the eccentrically-positioned fastener 17, and then the fastener is tightened to hold the member firmly in place. hen the portion of the wear member that has been subjected to friction of the running material has be come worn, the fastener is loosened and the disk turned on the washer to present another portion of the wearing surface to the material, whereupon the fastener again is ti ghtened.

A form of wear member attached directly to the guide is illustrated by Figs. 4: and 5. The wear member of this form is a disk 18 having a rounded peripheral wearing-surface 19, and it is secured to the guide by a machine-screw 20 or other suitable fastener, which passes eccentrically through the disk and through the limbs of a U-shaped clamp 21 embracing the shankof the guide. When the fastener is tightened, the limbs are drawn toward each other and the clamp thereby caused to grip the shank and the wear member is held firmly on the clamp. When the fastener and disk are loosened, the wearing-surface of the disk may be brought to the proper relative position with respect to the eye of the guide by turning the disk on the eccentrically-positioned fastener, or by moving the clamp along the shank, and in like manner another portion of the wearingsurface may be brought to position to sustain wear of the material after one portion has become worn.

Figs. 6 and 7 show a form of wear member, designated by 22, which is substantially of the form of a disk and which has in its periphery or edge a series of indentations or grooves 23. This member is secured to the guide in proximity to the eye thereof by a screw 24 or other suitable fastener passing through the member and guide in such position that by loosening the fastener and turning the member any one of the indentations or grooves may be brought to such position with respect to the eye that the material passing through the eye will run in the indentation or groove and take wear of the material.

It is to be noted that, when any one of the Wear members disclosed herein has become so worn that it is not susceptible of satisfactory use, it may easily be removed and replaced by another.

Having thus described my invention,

whatI claim as new, and desire to secure by Letters Patent, is

1. The combination, with a guide for thread or other material, of a wear member arranged to be contacted by material passing through the guide, a clamp on said guide, and a fastener adjustably holding said member to said clamp.

2. The combination, with a guide for thread or other material, of a wear member arranged to be contacted by material passing through the guide, a clamp on said guide, and a fastener arranged to hold said member in place and to cause said clamp to grip said guide.

3. The combination, with a thread-guide having a shank, of a wear member arranged to be contacted by material passing through the guide, a clamp longitudinally movable on said shank, and a fastener arranged to hold said member on said clamp and to cause the clamp to grip the shank.

4-. A wear member for guides for thread or other material comprising a disk formed with a central depression, the periphery of said disk being arranged to be contacted by material passing through the guide, and a washer seated in the depression and having an eccentric hole, there being an opening in said depression, and the arrangement being such that a fastener can be passed through the hole and opening.

In testimony whereof I aflix my signature in presence of two witnesses.
