Specification of Letters Patent.

Patented Aug. 19,1913.

Application filed July 27,1909. Serial No. 509,861.

To all'wlwm it may," concern:

Be it known that I, ALFRED ISHERWOOD, a citizen of the United States, and a resident of New Bedford, in the county of Bristol and State of Massachusetts, have invented a new and useful Improvement in Loom- Shuttles, of which the following is a specification.

My invention relates to loom shuttles and more particularly to threading devices for self-threading shuttles such as are used in automatic filling-replenishing looms or for common shuttles.

In a common. shuttlethe free end of the thread or filling from the bobbin is usually the mouth of the operator. In a self-threading shuttle, in which the side of the shuttle at the threading end is slotted or cut down, or otherwise constructed to allow the free passage of the thread, the threading may be done manually or substantially automatically. It frequently happens, however, that during the operation of threading an auto,- matic shuttle, the thread fails to pass through the eye and it also happens with both kinds of shuttles that occasionally the thread is ballooned outwardly or overthrown by the sudden stopping of the shuttle at the end of its throw thereby necessitating the stopping of the loom.

It is therefore one of the objects of my invention to provide a device whereby an automatic or common shuttle may be threaded either automatically or by hand, or par tially automatically and partially by hand in a more positive manner than is possible with the shuttles now in use, and whereby such ballooning or outward overthrowing ot' the thread may be prevented; and other objects are to provide a new and simple tension device which may be used separately or in conjunction with my threading device. and generally to improve the construction of shuttles in the manner hereinafter set forth. Several embodiments of my invention are shown in the drawings which accompany and form a part of this specification; but it will be understood that various modifications may be made by those skilled in the art without departing from the principle of my i n venti on.1

In the drawings-selected for illustrating the principle of my invention, 1 represents a self-threading shuttle provided with the usual metallic tip 2 and having a threadingblock 3 renu'ivably inserted in the throat or delivery-end and held in position by a bolt 3' or by other suitable means. ing-block which may be cast in brass or other suitable metal resembles in its general structure that shown and described in the patent to Northrop No. 926,016, dated June 22, 1909 and does not constitute a part of my invention except as hereinafter specified. The threading-block is provided with a slot 5 for, receiving the thread A from the bobb'ih and has a guard l overhanging said slot and provided with a lateral extension 4 extending outwardly toward the delivery-end of the shuttle. The downwardly and the rearwardly extending portion 4: of the guard is placed. opposite a groove 4 in the threading-block. The threading-block is also provided with a rearwardly and inwardly extending beak 6 which projects into the circumferential portion 8 of a slot in the eye 7 and serves as hereinafter set forth to guide the thread into said eye.

The eye 7 is preferably formed from a blank shown in Fig. 9 and is approximately circular in section throughout a portion of its length. This eye is provided with the above mentioned slot 8 which intersects the longitudinal slot 8' and the latter terminates in acircular hole 14 on the upperside of the eye. The inner lip 13 is formed by bending the portion of the blank shown at 13 in Fig. 9 under the surface of the eye so that thelip underlies a portion of the longitudinal slot 8 as most clearly shown in Fig. 10. The delivery-end of the eye near the front wall of the shuttle is provided with t1 7; downwardly extending curved lips 15 :t '16 formed by bending the portions of tlieigblank designated as 15 and 16 in Fig. 9.

The essential features of my invention as so far described consist in the guard 4, 4: with its cotiperating slot 4', the guiding beak 6 and the eye with its inner and outer lips.

When the shuttle above described is threaded either automatically or manually, the free end of the thread A from the bobbin is passed over the guardd, the slot 4: permits ting this to be easil done, through the slot 5 and under the hop 17, as the shuttle moves inwardly, and then as the shuttle moves outwardly the thread passes over the'beak 6 and is. guided thereby into the slot 8 of the eye, and then further outward movement of the shuttle causes the thread to pass over the inner lip 13 into the slot 8' and thence into the hole 14. The thread then passes through the space between the shuttle and the lip 15 which extends slightly below the transverse hole bored in the shuttle for re ceiving the eye 7 (as shown in Fig. 8) and is thereby prevented from leaving the eye. At the completion of the threading operation, the position of the thread in the shuttle'is as shown at A A in Fig. 1.

In the modifications shown in Figs. 4, 5

The thread,

and 6 the function of the outer lip 15 substantially is performed by the pin 10 which projects from the threading-block and passes into the slot 9 near the front wall of the shuttle. Furthermore by constructing this pin to fit fairly tightly in the slot, the thread may be placed under tension, the amount of which depends upon the closeness of the fit of the pin in the slot, and in such case the usual flannel tension shown at B may be eliminated. The eye 7 which I have described above in connectionwith the automatic shuttle may also be employed in the common shuttle shown at l in Figs. 7 and 8, in which the delivery end of the shuttle is provided with the slot 11 extending as shown diagonally across the top of the shut-\ tle and having its inner end terminating at the slot 8 of the eye and intersecting the longitudinal slot 12 formed in this front side of the shuttle. In this case the operator in stead of sucking the thread through the eye, grasps one end of the thread and passes it through the slot 11 thereby bringing it into the slot 8 of the eye and then draws it iri-. wardly through the slot 12, thereby causing the thread to enter the slot 8, to pass under the lip 13 and out into the hole 14, and finally to pass between the shuttle and the lip 15, whereupon the shuttle is'threaded and the position ofthe thread in the shuttle is as shown in Fig. '7 at A A.

In order to prevent the outward ballooning of the thread I may employ a guard which may also perform the functior of a tension device. This guard which is shown in detail in Figs. 17, 18 and 19, consists of a base 20 which is held in adjustable position in two slots cut in the throat of the shuttle, an upwardly extending piece 20 substantially at right angles to said base and an outwardly extending fiat piece 17, the corner 18 of which enters a groove in the shuttle above the eye 7 and is firmly held in position thereby. The piece 17 is provided with a rearwardly extending lip or ollset 19, which as shown in Fig. 7, fits loosely into a slot in theshuttle, the slot being large enough to permit the thread to pass over said lip. The flat piece 17 is curved through- 3 out its length on its rearward side as shown in Figs. 7 and 17. 22 is an eye which I may call a tension-eye consisting of a slit in the inward end of the guard, and 21 is an up wardly extending guard for said eye. The 3 eye 22 is so positioned with respect to' the hole 14 in the top of the eye 7 as to put the thread under tension, and in the present instance the eye 22 is placed below the hole 14 so that the thread must pass u an in cline from the eye 22 to the top of t e eye 7. The tension on the thread may be r ulated by turning the eye 7 in its socket, W enthe guard just described is employed, the thread is brought through the slot 11 and then the 1 and then over the I some inward movement of the thread through the 1 slot 12 will draw thethread over the lip 1-9 hereinbefore' described.

It will be understood from the above description that the eye 7 may be em loyed with an automatic or a common s the metallic tension described in connection with Figs. 4, 5 and 6, and that if used in a 1 common shuttle it may be employed with :or without the combined guard and tension device described in connection with Figs. 17

18 and 19, or with any other tension device.

In Fig. 14 I haveshown a modified form of eye that may be employed in either the automatic or mmmon shuttle. This eye 7 is provided with the circumferential and longitudinal slots 8 8, the lip'l3 and hole 14, all as above described in connection with Fig. 9. The hole 23 is cut in the wall of the eye near the delivery-end thereof and the interior ton ue 23 is bent to cooperate with said hole. in order to prevent undue tension on the thread as it passes between the tongue and hole, a portion of theshuttle may be cut away to form the recess shown at 24. In threading a common shuttle provided with the eye 7 the thread on passing through the slot 12 enters the slots 8 and 8 of the eye as hereinbefore described and then passes from the bottom of the eyesocket to the eye betwen the tongue 23 and hole 23, the said tongue which may project slightly into said hole serving to prevent the thread from leaving the delivery-end of the eye.

It will be understood that any suitable tension device, such as that shown in Fig. 18, may be'employed in connection with the eye as shown in Fig. 12. In Fig. 20 I have shownanother type of guard to prevent outward ballooning. This guard consists es sentially of the base 25 which slides through grooves in the throat of the shuttle to insure the proper positioning of the guard and two upwardly extending members, one of which shown at 2?,is an inverted U-sbapedmember provided with a hole 28, and the other a tongue 26 projecting into and ,Miperating with said hole. During the process of threading the shuttle, the thread will pass between the tongue and member 27 and will be thereafter guard and overthrowing into the slot 11 or catching on any other portion of the shuttle or loom. It will be understood that, the guards shown in Figs. 20 and 23 maybe employed with any suitablejension device and that required in certain classes of weaving the tension device may be omitted.

In Figs. 23, another type of guard located between the uttle, either with the usuai flannel tension or with the eye, and a lip in the prevented from leaving the leaving sald eye,

, of sand eye.

24 and 25 I have illustrated eye and the bobbin for the purpom oi venting the overthrowing of the thread. This guard comprises'a'base 32 which slides through grooves in the throat of the shuttle in the manner illustrated in Fig. 20 with respect to the base 25 of the guard therein shown.

The base 32 carries two rightangular over-lapping members 29 and30, the member 29 corresponding to the tongue 26 of the guardshown in Fig. 20 and the member 30 corresponding to the piece 27 shown in said figure. The

members

29 and 30 overlap and the latter may be provided with a hole 31 into which the tongue-shaped member 29 projects and with which it cooperates to prevent the thread leaving the guard. The

members

29 and 30 may as shown extend beyond their upright supports and the lateral extensions 33 may, if desired, slide in grooves cut in the throat of the shuttle to 'prevent the thread from catching in the space which otherwise might be left between the guard and inner wall of the shuttle.
