SHUTTLE.
APPLICATlON FILED MAR- 23. I915- Patented; 10cc. 4, 1917.
JEAN B. DAUDELIN, 0F FALL RIVER, MASSACHUSETTS.
SHUTTLE.
Application filed. March 23, 1915.
To all whom it may concern:
Be it known that I, JEAN B. DAUDELIN, citizen of the United States, residing at Fall River, county of Bristol, Commonwealth of Massachusetts, have invented certain new and useful Improvements in Shuttles, of which the following is a specification.
This invention relates to hand threading shuttles and particularly to a thread conductor and guard for the threading eye of such a shuttle to-prevent dethreading during its run.
The device of my present invention is especially designed for use where a hard drawn filling such as silk thread is being run through the shuttle, although of course it may be used with softer fillings.
The tendency of a hard drawn filling such as silk is to cut grooves in the friction surfaces of the usual metallic or wire threading eyes. This tendency is due to the fact that the hard unfleXing sliver exerts a greater friction on the parts than does a softer filling. Such filling is also difficult to draw in on account of its wiry na ture. That is, it does not run readily around corners and does not draw or creep as do soft fillings like cotton. It is therefore difficult to lead such filling through a tortuous channel.
In my present invention I have provided for a direct draw on the filling which causes it to lead past the deflecting points of the passage and to this end provide space so that it can be raised in threading in line with the highest parts of the threading passage.
The present invention contemplates a thread conductor of a construction and material which will not be liable to grooving by the hard drawn filling and which will effectively direct the filling into the eye and prevent improper escape thereof during the run of the shuttle. This-device is preferably made of porcelain or like material and is given a form best suited. to direct the thread into the conductor and prevent 1mproper escape therefrom.
The construction and operation of my device will be more fully disclosed in the specification that follows. In the drawings forming a part of that specification I have shown as anillustrative embodiment a form of guard which has proven'satisfactory in Specification of Letters Patent.

use and well adapted to the requirements of manufacture.
Throughout specification and drawings llke reference numerals are correspondingly applied and in these drawings:
F lgure 1 is a plan view of the threading end of a shuttle equipped with my inventlon.
Fig. 2 is a side elevation thereof.
Fig. 3 is a longitudinal section on the line 33 of Fig. 2. V
Fig. 4 is a transverse section on the line 4L i of Fig. 2.
Fig. 5 is a detail view of the thread conv ductor removed, and
Fig. 6 is a detail view of the eye guard removed.
The shuttle body 1 may be of any construction having a bobbin chamber 2 in which is located a bobbin 3 on which is wound. a thread T. The forward end or throat of the bobbin chamber opens up into an eye iwhich extends across the shuttle asa substantially cylindrical bore. The threading slots 5 and 6 communicate with the eye 4. In the form shown the slot 5 is diagonally disposed with respect to the longitudinal axis of the shuttle and is so sawed as to develop a curve on the top face of the shuttle. The slot 6 connects the slot 5 with the eye a and preferably enters said eye at a point near its top.
The thread T is guided into the slot 5 and is prevented from escaping therefrom by a slot guide and guard member 7 of any desired construction.
Between the bobbin chamber and the de livery end of the eye a said eye is counter bored along its top-wall as shown (see Fig. i) to receive the thread conductor. In the form of my present invention the thread conductor consists of a bushing 9 driven into the eye 4 and substantially filling said eye. The bushing is preferably made of some smooth vitreous material as porcelain or the like. The bushing has a shouldered bore 10 extending from the delivery end thereof to an integral upright portion 11 disposed adjacent the entry of the bobbin chamber into the eye and providing a thread guiding and snubbing post. The shoulder of the bore is indicated by the numeral 10. Beyond the post 11 the bushing has a cleared portion or notch 11 (see Fig. 4:)
communicating with the bobbin chamber and providing a passage through which the thread from the bobbin chamber feeds to the bushing after the shuttle has been threaded.
The bushing is split along its top edge as indicated at 12. The slot 12 enters the bore 10 of the bushing and isco-extensive therewith. This leaves a wall on each side of the slot and extending from the delivery end of the bushing to the friction post 11. The delivery end of the bushing is flared out as best shown in Fig. 5 to provide a smooth surface past which the thread may run.
The wall 14 of the bushing adjacent the plane of entry of the slot 6 into the eye 4 is beveled ofl' slightly along its topedge to provide a deflecting portion 14 adapted to direct the thread from said slot 6 into the slot 12 of the bushing. Beyond the beveled portion 14 the Wall 14 extends as an edge 16 which is gradually sloped downwardly and r'eawardly to a point adjacent the post 11 whereby to expose the bore 10 of the bushing. This provides a lateral entrance open ingl? through which the thread enters into the bore of the bushing as it runs down the sloped edge 16 of the wall 14. The thread is therefore carried up to its point of highest effective travel before it is laid in the threading passage of the bushing. The opposite wall 15 of the bushing extends into the counter bore of the eye back to the post 11 as a vertical fin 18 effective to prevent turning movement of the bushing in the eye.
Overlying the slot 12 of the bushing is a guard device for preventing escape of the thread back into the slot 6 or escape by a direct upward movement. This device may be of any desired form. In the embodiment illustrated, and referring particularly to Fig. 6 it is shown as consisting of a simple notched plate 19 having a pair of spaced legs .20 adapted to be driven into suitable holes in the side wall of the shuttle whereby to properly position said plate relative to the slot of the bushing. The notch of the plate is indicated at 21.
1 In practice the plate is preferably so set up as to position its notch 21 slightly to the rear of the slot 12 so as not to register with said slot. The edge of the plate between the notch 21 and the leg 20 nearest to the threading slot 6 is preferably developed on a curve as indicated at 22. This edge 22 assists with the beveled portion 14 of the wall 14 to direct the thread into the slot 12, afterthe thread has been drawn upwaidly to its point of highest effective travel. It
I also serves to prevent escape of the thread by a direct upward movement. Should this happen, the thread is deflected up into the notch21 from which it drops back .into the eye."
In threading the shuttle, the thread from the slot 6 is deflected by the portion 14 down along the gradually sloping edge 16 of the wall 14 and into the bore of the bushing, through the lateral opening 17 into said bore. The shuttle is now threaded. The thread then feeds direct from the bobbin chamber through the cleared portion 11, past the guide post which substantially bridges the space between the ports 11 and 17, and into the bore of the bushing Any tendency to escape by a direct upward movement is met by the shoulder 10 of the bore and if the thread twists upumrdly by this shoulder, it is prevented from escape by the plate 19 overlying said bore. The thread cannot therefore escape by any but its true path which is transversely out of the bush- Various modifications in the form and construction of my device may obviously be resorted to within the limits of the appended claims.
hat I therefore claim and desire to secure by-Letters Patent is:
