Specification of Letters Patent.

' Patented Oct. 9, 1917.

Application filed. February 24, 1917. Serial No. 150,782.

To all whom it may concern:

Be i' known that I, NAPOLEON Srmvneo, a

citizen oi the United States, residing at Biddeford, in the county of York and State, of Maine, have invented certain new and useful Improvements in Loom-Shuttles, of which the following is a specification, reference behad to the accompanying drawings. This, invention relates to improvements in loom shuttles and has'for its primary object to provide an improved guide for the weft thread to hold the same in proper position and prevent the thread from being accidentally displaced firom the threading de vice arranged in the weft chamber of the shuttle. I

It is another object of my invention to :provide a guide-eyefor the thread which is of such construction as to efi'ectually obt' iate the breaking of the thread, thus avoiding the necessity of frequently stopping the operation of the loom. It is another importantobject of the invention to provide aguide-eye for shuttles which is applicable to the various types of loom shuttles now in general use without necessitating any material alterations therein and which may also be manufactured :lrom. a single piece'of metal atrelatively small cost.

With the above and other objects in view, my invention consists in the novel features of construction, combination and arrangement of parts to be hereinafter more fully described, claimed and illustrated in the accompanying drawing, in which,

Figure l is a longitudinal section of a well lmown type of loom shuttle showing my improved gnideeye arranged in operative rei1 n-with the threading device in the weft chamber;

Fig. 2 is a section taken on the line 2-2 of Fig. 1; and v Fig. 3 is an enlarged perspective view of the eye.

Referring in detail to the drawing, A indicates the shuttle and B the bobbin which is located in the Weft chamber 0. With this chamber, the threading channel 1) in the nose of the shuttle, communicates. Within this "channel, a metal threading device of any that the several parts just referred to are well known in the art and constitute no part of the present invention.

My invention illustrated in detail in'Fig. 3 of the drawing, is adapted to be arranged at the inner end of the threadin channel D and between the side walls 0? the metal threading device E. The eye is formed from a metal plate 5 which isstamped out or cut to provide the substantially circular opening 6 therein with which the lower, relatively narrow end of an entrance throat 7 communicates at one side of said opening. One edge of this entrance threat is obliquely inclincd, asshown at 8, and from the lower end of this inclined edge an integral part of the metal plate projects and is bent or in clined laterally from the plane of the plate, as shown at 9. The end of this arm or pro jection is formed with a coil 10 therein, the center of which coincides with the center of the opening 6 in the plate 5. The opposite edges of the plate 5 are notched or recessed, as shown at 11, to receive retainin ,lugs or projections on the side Walls of th threading device E, whereby the eye plate is held in position against vertical or lateral shifting movement.

The thread or filling is drawn from the bobbin through the channel D and the threading device arranged therein in the usual manner, the thread being inserted downwardly between the retaining wings or flanges of the threading device and directcd by the inclined edge 8 of the eye plate into the opening 6 thereof. The thread is again brought upwardly against the edge of this opening and into contact with the laterally bent or inclined extension 9 which directs the thread into the eye 10. The thread is thus supported by this eye and is freely movable therethrough as it is withdrawn from the bobbin in the operation of the machine. By providing the supporting or guide eye for the thread of the construction described, the tangling or breaking of the thread in the operation of the loom is prevented and the thread is at all times properly supported for free movement through the threading device and the side eye in the nose of the shuttle. It is unnecessary to make any changes whatever in the mounting or arrangement of the bobbin or the construction of the latter in order that the present invention may be adapted to the common construction of loom shuttles.

From the foregoing description, taken in connection with the accompanying drawing, the construction, manner of operation and several advantages. of the device will be clearly and fully understood. 'The thread eye being formed from a single metal plate may obviously be manufactured at small cost and is also very durable in practical use. The eye may be readily arranged in position with relation to the threading device and may be usedin connection with various constructions of such threading devices without necessitating any material alterations therein. It will, of course, be understood that the eye can be made in various sizes as may be required in accordance with the particular. type or construction of the shuttle. Therefore, while I have shown and described the preferred form and arrangement of the several parts of the device, the same is susceptible of considerable modification therein and I reserve the privilege of adopting all such legitimate changes as may be fairly embodied within the sprit and scope of the invention as claimed.

Having thus fully described my invention, what I desire to claim and secure by Letters Patent is:

1. A throat guide for 100m shuttles consisting of a fiat metal plate having an opening therein and an entrance throat communicating with said opening, said plate having an extension formed integrally therewith at one side of the entrance throat,

said extension being of. circular form in.

cross-section and bent to provide a single thread receiving coil therein terminating on an imaginary line extending through the opening in spaced relation to the edge thereof.

2. A throat guide for loom shuttles consisting of a flat metal plate having an opening therein and an entrance throat communicating with said opening, an extension integrally formed with the plate at one side of said entrance throat and sharply ofiset in a lateral direction from one side of the plate, said extension being formed into a single thread receiving coil disposed in substantially parallel relation to the plane of the plate.

3. A throat guide for loom shuttles consisting of a fiat metal plate having an opening therein and an entrance throat communicatingwith said opening, said plate being further provided with a laterally ofiset, thread receiving eye disposed in spaced relation to said opening and in substantially parallel relation to the plane of the plate.

4. As an improved article of manufacture, a throat guide for loom shuttles consisting of a fiat metal plate having an opening therein and an entrance throat communicating with said opening, one edge of the entrance throat being obliquely inclined, and an extension integrally ermed with the plate and projecting laterally from the inner end of said inclined edge of the throat, said extension being formed into a single thread receiving eye disposed in spaced relation to said opening.

In testimony whereof I hereunto aifix my signature in the presence of two witnesses.
