To all whom "it may concern:

Be it known that we, WILLIAM F. D'RAPIGR and JONAS Non'rnnor, citizens of the United States, and residents of llopedale, county of Worcester, State of Massachusetts, have in vented an Improvement in Shuttles for Automatic Filling Heplenishing Looms, of which the following description, in connec tion with the accompanying drawing, is a specification, like numerals on the drawing representing like parts.

This invention relates to shuttles for use in looms in which mechanism is provided to replenish automatically the running tlilling prior to complete exhaustion thereof, and it is a division of an application for United States Letters Patent Se. No. 403111 filed by us November 21, 1907, in which application the shuttle forming the subject-matter of this present application is shown and described.

One of the novel features of our present invention is the provision, in a loom shuttie, of means whereby the old idling-end is absolutely and positively cast off and the shuttle completely unthreaded at the time of filling replenishment, the casting oil bod ily of the old filling from the shuttle being distinguished from drawing the filling lengthwise through the delivery eye of the shuttle.

Other novel features of our invention will be fully described in the subjoined speciiication and particularly pointed out in the fol lowing claims.

Figure 1 .is a top plan view of the threaddclivering end of a loom-shuttle embodying our invention l 2 is a side elevation thereof; Fig. 3 is an underside view of the tln'ead-delivering end of the shuttle; Fig. it is a transverse section on the line -l--5, .l ig. 1, looking toward the left; Fig. 5 is a similar section, but looking toward the right, Fig. i. Fig. 6 is a partial longitudinal section on the line 67, Fig. .l, but showing the fillingsupport and the thread-directing device in elevation Fig. '7 is a view similar to Fig. (i but showing the old filling-end just about to be cast off; Figs. 8 and 9 are perspective views of the thread-directing device, detached from the shuttle-body.

In the construction of the shuttle, we have had in view the complete and positive discharge or casting oil therefrom of the old ['lillingend at the time of replenishment, so that by no possibility could such old fillingend or any part thereof be carried back into the cloth or left in the shuttle to foul or in lerfere with the new filling inserted at the time of replenishment, and in order to effect such cast oil, the device on the shuttle to direct the new filling to the delivery-eye has been located at the bottom of the shuttle, so that the shuttle may be said to be threaded at the bottom.

in practice the shuttle-body 1 has the usual elongated o )ening 2 to receive the tilling-carrier or bob in, one end of said opening having therein any suitable or usual means (not shown) for grasping and holding the bobbin in position, and the front wall of the shuttle is also provided with an aperture, (not shown) for the intermittent entrance of a fcclcr to feel the yarn on the bobbin, as is usual in shuttles arranged for fccler looms. The opposite or thread-delivering end of the shuttlebody is provided with an opening or well 3 extended completely through the shuttle and separated from the bobbin-receiving opening or chamber 2 by a transverse wall or partition 4 slotted from top to bottom at 5, the upper and lower edges of the partition l being preferably convcxed, as best shown in Fig. 4. A filling-support shown as a metallic plate 6 is fixedly secured at one side as at 7 to the side wall of the well 3 and extends transversely across the slot and (uite near the same, see Figs. 1, S and (3, the free end of the support being bent forward at 8, and down turned adjacent but at a slight distance from the opposite wall of the well, leaving a clearance 9, as shown in i igs. b and 4, the shuttle-body being undercut at 10, to form a species of housing for the depending end of the support.

Referring to Fig. 4, it will be seen that the upper edge of the support is gradually inclined from right to lcft,'from a point at the 1 right hand side of the slot 5 down to the tip of the part 8.

In practice, a piece of llannel, felt or other suitable friction-prmlucing material 11 is iuterposed between the adjacent part of the wall 4 and the enlargement 12 of the iillingsupport, such friction material at its upright edge extending somewhat across the line of travel of the filling as it is drawn through the slot 5 and over the upper edge of the support 6, when the filling is being delivered from the shuttle.

il hen the filling is drawn forward, as it will be under normal conditions, it will be held the proper height in the slot 5 by the transverse support, and cannot drop below it, but the peculiar shape and location of the support as described provides for the shedding or casting o of the old 'ng-end at the time of replenishment, permitting its escape downward through the clearance 9, when the spent bobbin is ejected from the shuttle, as will be explained.

The shuttlc-bod is cut away at its bottom in front of the well 3 to receive the threading device, preferably made as a metallic block 13, having a lug 1a to fit into a suitable socketin the shuttle-body and held in place by a transverse screw-stud 15, Figs. 6 and 7, the block having extended through it a i'lilGEtCl-PEiSSSg'G 16, at its rear end presenting a downturned and narrow entrance 17, Figs. and 5. The block 13 is laterally extended at its base at opposite sides of the open bottom 18 of such thread-passage as at 19, 20, S, the enlargement 19 havin its forward dge curved and forming the side a guard lip 2 1 a second guard lip 22 being formed above it, and into the concavity between the said lips projects rearwardly extended beak 23 forming part of a horn hich extends from the side the enlargement 19 forward to the tip of the opposite enlarged portion 2(1- cf the base of the block The wall of the thread passage at its front end above the enlarged portion 20 is shaped to present a prong 25, which prevents the dropping of the thread out of the thread passage 16 at the time the directing device is guiding the thread to the side deliveryeye 26, this delivery-eye being herein shown formed in the casing of the threaddirect ing device, and located immediately above the guard lip 22.

Referring to Figs. 2, 6 and 7, it will be seen that the delivery-eye 26 is not only at the side of the shuttle-body, but it is also very near the bottom thereof, so that the thread or filling is deliv red from the shuttle quite close to the raceway of the lay.

V v hen the shuttle is in use in a loom such as is described in our co-pending application Se. No. 103111 a thread-positioner positions the new filling-end when the fresh supply of filling is inserted in the shuttle, and a threadcatcher is moved upward through the well 3 of the shuttle and grips or clamps the filling-end, the thread-catcher drawing the filling-end downward. through the well 3 and across the filling-support 6, but there is no tendency at such time to shed the filling therefrom as it is sustained back of the support by the bobbin. As the shuttle is picked the thread-catcher maintains its hold on the new filling-end and the latter is properly positioned to enter the inlet 17, and the open bottom v18 of the thread-passage 16, as the shuttle moves across the lay, and the thread. is drawn up over the prong 25 and under the edge of the horn 2 1, adjacent the upright face 27 of the enlargement 20 as the shuttle continues its movement to the nonreplenishing side of the lay. The filling thus laid is beaten in, and after the change of shed the shuttle is again picked, in the opposite direction, toward the replenishing side of the loom, and the filling now draws backward, being guided by the horn. 24, and over the guard lip 21 and beneath the beak 23, immediately slipping over the guard lip 22 and into the delivery-eye 26. The shuttle is now completely and permanently threaded, and delivery of the filling continues from the eye so long as the filling cannot escape from the eye because the guard lip 22 overhangs the beak 23, and the point of the beak is shrouded or protected by the upper and lower lips 22 and 21 over which the filling draws, so that once in the eye, it is impossible for the filling to escape therefrom during the normal operation of the shuttle. There is no opportunity for the filling to drop out of the narrow inlet 17, because the support 6 holds the filling up, and in the thread passage.

Viewing Fig. 6, the filling 28 is shown as it passes from the filling-carrier 29 across the supoort 6 and thence through the well 3 to the thread passage 16 and around the front face of the enlargement 19, and out through the eye 26, the said. face being somewhat concaved or grooved at 30 leading to the eye to more smoothly and accurately direct the thread to the eye. After the threading of the shuttle is completed, it cannot be unthreaded by any throwing forward of a loop of filling, because such loop would be thrown forward out of the top of the well 3 and onto the perfectly plain and unbroken surface of the shuttle-body in front of such well, and would be eliminated by the delivery of the filling. Such a loop would not be thrown under the shuttle, as all loop-forming tendencies operate to throw it forward at the top of the shuttle. objectionable feature sometimes found to occur in the use of automatically self threading sl nttles, as heretofore constructed,

where the filling-thread is directed to the deliveryeye by directing means located at the top of the shuttle, loop when formed tending to catch over such device and causing breakage of the filling.

As the filling is firmly held in practice at the proper level with relation to the bottom of the shuttle, the introduction of the filling into the thread-passage of the directing or guiding device on the shuttle is accomplished very accurately and positively with a minimum liability to misthread at the time of replenishing, and as the complete threading Vie thus eliminate an of the shuttle is a practical certainty after the filling has once been introduced to the thread -passage 16, shuttle misthreads are obviated by the construction set forth.

When the shuttle is in the replenishing box, the filling-end extends from the edge of the cloth to the delivery-eye, thence through the thread-passage of the directing device and across the well 3 in the shuttlebody, and over the support 6 to the fillingcarrier, and this condition obtains when a change of filling is to be effected.

The shuttle invented by us is constructed and arranged to cast off or shed from the shuttle positively and wholly the old fillingend by or through the ejection from the shuttle of the spent filling-carrier or bobbin, meaning thereby the one on which the filling has been exhausted to a predetermined extent. When the bobbin is ejected from the shuttle it passes therefrom down through the usual open bottom of the shuttle-box, the tip of the ejected bobbin being shown in. dotted lines at 31, Fig. 6, with the filling-end 32 shown in dotted lines as leading therefrom up to the support 6, and in practice the loom is provided with means to temporarily arrest or stop the ejected bobbin just below the shuttle-box, thereby preventing a quick drop which might break the old filling-end and leave it in the shuttle, but as said means forms no part of this invention and is illustrated in the co-pending application referred to it is not shown herein. The dotted lines indicating the tip 31 of the ejected bobbin in Fig. 6 show such tip in substantially its arrested position.

As the ejected filling-carrier descends it draws the filling-end 32 downward and forward, so that it slides along the inclined. upper edge of the support 6, as shown in dotted lines Fig. 4, and finally drops or is drawn oil or shed from the tip 8 of the support, and there being then nothing to retain it in the thread-passage, the filling-end drops out of such passage and just before complete cast off of the old filling-end from the shuttle the bight or loop formed. by such old filling-end assumes substantially the position illustrated in Fig. 7, wherein it is shown as just about to escape from under the beak -3 between the guard lips 21 and 22. The old filling-end is thus cast off bodily and completely, and in a positive manner from the shuttle by or through the ejection of the filling-carrier therefrom. This east-off is effected manifestly by the ejection of the filling-carrier from the shuttle but in actual practice the old filling-end is engaged and held by the threadcatching device previously referred to and thereby the old filling-end is drawn downward, assisting the ejected filling-carrier in shedding or casting off the old tilling-end from the shuttle. Such casting off will be effected, however, even if the old filling-end is not ongaged and drawn downward. This cast-off of the filling-end is to be distinguished from a drawing-out of the filling-end longitudinally through the eye of the shuttle, for heretofore, so far as we are aware, the only way in which the old filling-end has been removed from the sluiittle (when it was removed) has been by a longitudinal pull, and if the length of the lilling-end was too great or the pull was iusufiicicnt, the lilling was not removed from the eye and the movement of the shuttle after replenishment would be very apt to carry the old filling-end or piece of it back into the cloth to be woven tllm'LlilltO.

lnasn'rueh as we have provided for the complete cnst-olf of the old filling-end from the shuttle, it will be obvious that under no circumstances and by no possibility can any part of such old filling-end he carried back into the cloth. before the new filling-end is presented to the thread directing device on the shuttle. Hence there :an be no fouling or commingling of the old and new filling-ends The backward movement of the lay releases the ejected filling-carrier (which has been temporarily arrested) in such a way that when it draws oil' from the tip, preventing any breakof the filling, so that the ejected fillingcarrier does its part in casting oil the old filling-end from the shuttle.

is the old lillin -cnd al\var"s extends from the cloth through the delivery-eye of the shuttle to the bobbin about to be ejected, in a feelei loom, when replenishment of .iilling is called for, the shuttle forming the subjectnuatter of this application is particularly des gned for such looms, and so far as concerns the invention any desired form of fillj ing-exhaustion-indicating mechanism may be employed in connection therewith.

fi e believe it to be broadly new, in a loom shuttle, to prmide means constructed and arranged to permit the e'il'ectual and com plete cast off of the old 'li ling-end from the shuttle upon ejection therefrom of the boi1- bin, and we also believe it to be |.=roadl v new to ell'ect the threading of the shuttle from its under side or bottom.
