' T all'wlwm e'z may concern:

Be it known that I, Fnnn mn (less, a citizen of the United Staten-and residing at Brooklyn, Kings County, State .of llew York, have invented certain new. and useful Improvements in Thread Guides for Spin;

hing .Liachines, of which the following-is a specification. j

In modern textile machinery it is customary to employ thread guides made of porcelain or other vitreous material, these guides being formed with an aperture or eye through which the threadtravels. On a'c count of the vibration of the threads, they are apt to become disengaged from the guides. To prevent'this the guides are gen erally made with one or more small fingers extending into the eye or aperture. These lingers being somewhat slender are apt to bec ome broken and the guides themselves sometimes break causing annoyance and oiflicultv. This invention has for its object to provide a guide of the kind in question which is simple and strong in constriutlon andin whichthe parts are so shaped as to prevent disengagement of the thread therefrom. s

In the accompanying drawing there 1s illustrated in elevationand partly in section a thread guide embodying the present invention.

The guide as shown in the drawing com-' prises a body, generally designated by the numeral 10, which is provided at its lower end with a. socket 11 adapted to receive a wire or other supporting device 12, such device being secured in the socket by a plug of shellac or other suitable substance 18. The upper portion of the body 10 is provided with an upper eye 14 anda lower eye 15 which are connected by a channel or passage 16. A slot-01' passage 17 extends up war'dly and inwardly from one side or edge of the body 10 and communicates with the channel 16 between the eyes 14: and 15. For convenience of'desoription the side of the body 10 containing the inclined slot 17 may be regarded asthe front side. It will be seen that the rear wall of the eyes 14: and 15 extend rearwardly-of the point at which the is preferably spar-ed a somewhat greater distance from the rear side of the body 10 than is the'rear wall of the eye 1 1.. This tends to prevent breaking of the body of the guide back of the eye 15. The rear wall ofthe channel 16 is preferably curved forwardly which results in strengthening that part of the body between the eyes 14 and The upper wall 18 of the slot 17 is preferably made substantially straight and the lower wall 19 of this slot icurves rearwardly and downwardly. That part of the body between the bottom of the eye it and the top wall of the slot 17 forms in effect an upper rearwardly prOJecting finger designated 20 onthe drawing and similarly that portion of the body 10 between the upper wall of the a greater extent than the finger 21, the re sult being that if the thread which normally passes through, the eye "14 becomes disengaged, therefrom and falls downwardly it will tend to enter the lower eye 15, the curvature of he upper and rear portion of the finger 21 facilitating this action.

The foregoing construction therefore provides a guide in which the parts may made strong and durable and in which the parts are so arranged as to effectively retain the threads in proper engagement with the guide.

Havingthus described the invention what is claimed as new and desired to be secured by Letters Patent is: o T

1. A thread guide for textile machines comprising a body having an upper eye and a lower eye and a channel extending be tween the bottom ofsaid upper eye and the top of said lower eye, said channel opening into the bottom of said upper eye and into the top of said lower eye at points intermediate the front and rear walls of said eyes, the rear wall of said channel between its point of communication with said eyes being curved forwardly, said body also having an upwardly inclined slot extending rearwardly from oneside thereofand communicating with said channel opposite the curved rear wall thereof, the material of said body between the bottom of said upper eye and the top wall of said slot forming an upper rear- Wardly. projecting finger and the material between the upper wall of said lower eye and the bottom wall of said slot forming a lower rearwardly projecting finger, the inner end of said upper finger projecting rearwardly to a greater extent than said lower finger, and the rear wall of said lower eye being spaced from the rear wall of the guide a greater distance than the rear wall of said upper eye.

2. A thread guide for textile machines comprising a body having an upper eye and a lower eye and a channel extending between the bottom of said upper eye and the top of said lower eye, the rear wall of said channel between its point of communication with said eyes being curved forwardly, said body also having an upwardly inclined slot ex- 1,aee,577

tending rearwardly from one side thereof and communlcating with sald channel opposite the curved rear wall thereof, the material of said body between the bottom of said upper eye and the top wall of said slot forming an upper rearwardly PIOJQCtlIlg finger and the material between the upper wall of said lower eye and the bottom wall of said slot forming a lower rearwardly pro- FREEMAN GAS s.
