- the invention to be, hereinafter described relates to shuttles, and more particularly to Shuttles employedin looms for weaving.
- the ordinary loom shuttle used in what isgenerally known as the common loom is provided with a skewer or spindle hinged at one end to the; shuttle body, and when a filling carrier or bobbin supplied with filling;

- Filling replenishing looms are of two general types, those that, effect replenishment by changing the filling carrier or bobbin in the shuttle, andthose that change the shuttleitself. In either case, however, it is desirable in weaving some grades of fabrics to effect replenishment of filling when that in the active shuttle reaches substantial eX haustion.
- One means familiar to those skilled in the art for bringing about such replenishment consists of a feeler motion having a part that feels for the filling in the Shuttle on the detecting beat of the lay, and when it finds the filling to be substantially exhausted sets a ⁇ train of mechanism in condition for replenishing the filling.

- the filling carrier or bobbin must be positioned in the shuttle so that the open ing or slot in the carrier or bobbin shall be presented opposite the feeler on the detectlng beat, and since the feeling part of the feeler enters the slot or opening in the carrier or bobbin,,it is desirable that its proper action shall not be impaired by the presence of the skewer or spindle employed to hold the carrier or bobbin in the shuttle.
- the means for holding the filling carriers or bobbins in the shuttles shall be such as to permit the operative to readily remove the old or depleted carrier or bobbin by 'hand, and replace it by one having a working supply of filling.
- An important feature of the present invention therefore, consists in a shuttle wherein the carrier or bobbinholding means comprises jaws for engaging the exterior of the carrier -or bobbin and a fixed fulcrum point on the shuttle for engagement by the carrier or bobbin as it is turned into operative relationwith said jaws.
- Another important feature of the invention consists in a shuttle having bobbinholding jaws and a fulcrum point between the planes passing longitudinally of said jaws about which the bobbin is turned as it is moved into operative relation with said
- a still further feature of the invention consists in guiding means for guiding the bobbin as it is turned about its fulcrum into operative relation with the bobbin-holding aws.

- the end of the shuttle remote from the delivery eye is provided with bobbin-holding jaws adapted to engage projections or rings upon the base .or head of the bobbin. It would be diilicult ordinarily, to insert a bob-' bin between the holding jaws, because these jaws must be made sufliciently stiff to hold the bobbin firmly when in position between them; and difficulty would also be experienced in removing a bobbin from between said jaws, because in the absenceof means to prevent it, the bobbin if swung outwardly,

Applicationfiled February 5, 1916.. Serial N 0. 76,270.
To all whom it may concern:
Be it known that I, UBALD HEBEBT, a citizen of the United States, residing at,
Manchester, in the county of Hillsboro and State of New Hampshire, have invented an Improvementin: Shuttles, of which the following description, in connection with the accompanying drawings, is a specification,
like letters on the drawings representing like parts.
The invention to be, hereinafter described relates to shuttles, and more particularly to Shuttles employedin looms for weaving.
The ordinary loom shuttle used in what isgenerally known as the common loom is provided witha skewer or spindle hinged at one end to the; shuttle body, and when a filling carrier or bobbin supplied with filling;
is to be placed in the shuttle, the skewer or spindle is swung upon its pivotal connection with the shuttlebody to carry the free end of the skewer or spindle outside the shuttle. The filling carrier or bobbin is then placed upon the skewer or spindle and the latter is swung into the shuttle again or back to initial position. Such shuttles are provided at one end with athread. eye through which the end of the filling or yarn in the shuttle is threaded by the loom operative or by hand.
Filling replenishing looms are of two general types, those that, effect replenishment by changing the filling carrier or bobbin in the shuttle, andthose that change the shuttleitself. In either case, however, it is desirable in weaving some grades of fabrics to effect replenishment of filling when that in the active shuttle reaches substantial eX haustion. One means familiar to those skilled in the art for bringing about such replenishment consists of a feeler motion having a part that feels for the filling in the Shuttle on the detecting beat of the lay, and when it finds the filling to be substantially exhausted sets a} train of mechanism in condition for replenishing the filling. In its feeling action the said part may enter a slot or opening in the filling carrier or bobbin when the filling is substantially exhausted, and be not moved on the detecting beat of the lay. WVhen Such form of feeleris employed, the filling carrier or bobbin must be positioned in the shuttle so that the open ing or slot in the carrier or bobbin shall be presented opposite the feeler on the detectlng beat, and since the feeling part of the feeler enters the slot or opening in the carrier or bobbin,,it is desirable that its proper action shall not be impaired by the presence of the skewer or spindle employed to hold the carrier or bobbin in the shuttle. On the other hand, however, when replenishment is effected by changing shuttles, it is important that the means for holding the filling carriers or bobbins in the shuttles shall be such as to permit the operative to readily remove the old or depleted carrier or bobbin by 'hand, and replace it by one having a working supply of filling.
An important feature of the present invention, therefore, consists in a shuttle wherein the carrier or bobbinholding means comprises jaws for engaging the exterior of the carrier -or bobbin and a fixed fulcrum point on the shuttle for engagement by the carrier or bobbin as it is turned into operative relationwith said jaws.
Another important feature of the invention consists in a shuttle having bobbinholding jaws and a fulcrum point between the planes passing longitudinally of said jaws about which the bobbin is turned as it is moved into operative relation with said A still further feature of the invention consists in guiding means for guiding the bobbin as it is turned about its fulcrum into operative relation with the bobbin-holding aws.
The above and other features of the invention will be described hereinafter and then will be made the subject of claims.
In the drawings Figure 1 is a plan view of a loom shuttle, parts being broken away, showing one form of the present invention;
Fig. 2 is a longitudinal section on the lines 22, Fig. 1;
Fig. 3 is a sectional view similar to that of Fig. 2 with certain parts in elevation, showing the first position of a filling carrier .or bobbin as it is being placed in the shuttle by hand;
Fig. 4 is a view similar to that of Fig. 3, but showing the filling carrier or bobbin turned into operative position in the shuttle;
. comprising a tubular portion 3 leading into a side delivery portion 4*, but the thread eye may be of any usual character whereby the filling leading from the carrier or bobbin may be placed therein for delivery as the shuttle travels across the lay.
Shuttles of the typeused in common plain looms have a skewer or spindle pivotally mounted therein for receiving and holding the carrier or bobbin and its load, but this invention contemplates that such skewer or spindle shall be omitted and means be provided which shall enable the bobbin to be readily turned by hand about a fixed point into or out of holding engagement with the bobbin-holding jaws, as will now be described.
The end of the shuttle remote from the delivery eye is provided with bobbin-holding jaws adapted to engage projections or rings upon the base .or head of the bobbin. It would be diilicult ordinarily, to insert a bob-' bin between the holding jaws, because these jaws must be made sufliciently stiff to hold the bobbin firmly when in position between them; and difficulty would also be experienced in removing a bobbin from between said jaws, because in the absenceof means to prevent it, the bobbin if swung outwardly,
would turn about an axis extending from onejaw to theother and still be clamped between the aws. The present invention, therefore, contemplates a fulcrum polnt or lug ,carri'ed'by the shuttle in such position The bobbin-holding jaws may be variously contrived, and secured to the shuttle body, and likewise the fixed fulcrum point or lug to be engaged by the base of the bobbin may be variously formed, and related, to the holding jaws. In the present instance, the shuttle is recessed at i and the bobbin-holding jaws 5 extend from a part G'held in said recess by suitable means, such as the screw 7. The part 6 may be formed as a block from which thejaws 5 curve, as at 8, to the bobbin-holding portions which may be provided with the usual recesses 9 adapted to engage suitable projections or rings 10 secured to or forming part of the bobbin head or base, as indicated in Figs. 3,4 and 5. The fulcrum or lug to be engaged by the bobbin and about which the bobbin is turned as it is swung into or out of engagement with the bobbin-holding jaws, isconnected to the shuttle-body between the jaws or between planes passing longitudinally of the jaws. invention, the fulcrum is formed as a lug 11 projecting from the metal strip 12 which may be extended toward the end of the shuttle, as in Figs. 2, 3 and 4 and secured in place by suitable means, such as the screw 13. The strip 12 in this instance of the invention has an inclined portion 14: between the jaws from which the fulcrum lug 11 extends, and its lower portion 15 is turned frontwa'rd or toward the end of the shuttle to underlie the block 6.
The base portion of the bobbin as indicated in Fig. 6 is provided with an opening 16 adapted when the bobbin is placed in position as in Fig. 3, to engage the fulcrum or lug 11, and in order that'the bobbin may be turned downward from the position of Fig. 3 about the fulcrum 11 as a center without binding thereon, the fulcrum is preferably formed conical in shape as indicated in Figs. 1 and 2. This conical formation of the fulcrum point is preferred, but it is obvious that its contour may be variously formed, the essential in this respect being that it shall be adapted for engagement with the recessed head portion of the bobbin as indicated in Fig. 3 to enable the bobbin to be turned downward about said fulcrum for bringing the projections or rings 10 on the bobbin into holding engagement with the holding grooves 9 in the bobbin-holding aws.
Extending from the upper portion of the bobbin-holding grooves 9 in the jaws 5 are the incline grooves 17 which, when the bobbin is in position as indicated in Fig. 3, are adapted to initially engage the projections or rings 10 on the bobbin, the construction In the present instance of the being such that as the bobbin is turned 7 downward from position as indicated in Fig. 3 into holding relation with the bobbinholding aws as indicated in Fig. 4:, the incline groove portions 17 engaging the projections of rings 10 restrain the bobbin from longitudinal movement, and direct it downwardly about the fulcrum 11 as a center into holding relation with the bobbin-holding jaws. These incline grooves 17, as indicated in Fig. 33, extend from the top portion of the bobbin-holding groove?) in a direction upwardly and toward the bobbin-holding end of the shuttle.
From the construction thus far described, it will be seen that the shuttle is not pro-' vided with a skewer or spindle and that when a bobbin is to be placed in the shuttle,
the recessed portion 16 thereof is first engaged upon the fulcrum or lug 11 at which time the projections or rings 10 on the bobbin head or base are in position for engagement with the up wardly' and outwardly inclined grooves 17 of the bobbin-holding jaws, and upon the application of downward pressure to the free end of the bobbin, the projections or rings 10' on the bobbin head are guided downwardly by the grooves 17 into bobbin holding relation with the grooves 9 ofthe bobbin-holding jaws until the parts have assumed position indicated in Fig. a, at which time the bobbin is firmly held between the bobbin-holding jaws. Likewise, in removing a bobbin from the shuttle, the parts being in position as indicated in Fig. 4, the free end portion of the bobbin is seized by the hand of the operative and turned upwardly, whereupon the re cessed portion 16 at the base of the bobbin again turns about the projection 1.1 as a fulcrum, with the result that the projections or rings 10 are readily turned upwardly, out
of engagement with the bobbin holding jaws, and the bobbin can be taken directly from the shuttle.
In a filling replenishing loom of the type wherein a feeler mechanism is employed to feel for the filling in the shuttle on the de tecting beat of the layand, when the filling has become substantially exhausted, enters a recess or slot 21 in the bobbin, it is necessary that the slot or recess 21 in the bobbin shall be positioned for the entrance of the feeler. To this end, the bobbin and shuttle are provided with interengaging guiding members which shall determine the rotative position of the bobbin as it moves to its operative position in the shuttle as indicated in Fig. 4. These interengaging members may be variously formechand in the present in stance the bobbin is provided with a portion 18, Figs. 5 and 6, having the slabbed-ofl portions 19 at thesides which are adapted to engage guides 20 secured to the shuttle so that as the bobbin is turned downwardly from the position of Fig. 3 to that of Fig. 4, the portions 19 ofthe bobbin may engage the guides 20 and be held from rotative movement.
The guides 20 have at their upper portions outwardly-flaring guide wings 22 which, when the bobbin is placed in initial position as indicated in Fig. 3, engage the slabbed-oif portions of the bobbin and direct it in proper rotative position into engagement with the fulcrum 11. The guides 20 in the present instance of the invention extend from the wings 22 forwardly, one at each side of the strip 12 and are preferably connected as at 23, Figs. 1 and 2, that they may be held in operative relation.
In order that the bobbin-holding aws and the guides 20 maybe properly supported at their lower portions, there may be provided a plate 24 underlying the portion 15 of the strip 12 and having its side portions 25 extending beneath the lower edge of the bobbin-holding jaws and guides 20, the con struction being such that the parts will be maintained in their operative relation, substantially as indicated in Figs. 1 and 2.
From the construction described as one practical form of the present invention, it will be noted that the shuttle may be interchangeably employed for a shuttle-changing loom of the feeler type or a common loom, and while the construction described has been found to be a practically eliicient form of the present invention, it will be understood that the parts may be variously changed and that the fulcrum 11 may, if desired, be detachably connected to the shuttle, substantially as indicated in Fig. 2; and it will be further obvious that so far as the fulcrum is concerned, it may be variously connected to the shuttle, the essential in this respect being that it shall act as a center or fulcrum point about which the bobbin may be turned into and out of operative relation with the bobbin-holding jaws.
While the shuttle and bobbin as above described are well adapted for filling replenishing looms of the shuttle changing type employing a feeler motion, and are adapted for interchangeable use in such looms and the common loom, it is to be understood that the present invention is not restricted to such use, as it may be employed in other relations and in any loom where the filling carrier or bobbin is to be placed in or taken from the shuttle by hand.
