ALoNzo E. RHOADES, or HornnALE, MASSACHUSETTS, Assienon TonRAPEa oon- PoaATIoN, or HorEnALE, MASSACHUSETTS, A CORPORATION or MAINE.`
SHUTTLEFEELER THR-EAD CUTTER.
Application filed January To all 107mm t may concern.'
Be it known that I, ALONZO E. RHoADEs, a citizen of the United States, residing at Hopedale, in the county of VVorcester and State of Massachusetts, have invented an Improvement in Shuttle-Feeler Thread Cutters, of which the following description, in connection with the accompanying drawings, is a Specification, like `characters on the drawings representing like parts.
This invention relates to Shuttle feeler thread parters or cutters whereby the spent filling between the cloth selvage and shuttle is parted when filling replenishment is to be effected.
As now ordinarily constructed, shuttle feel er thread cutters are'mounted upon the shuttle feeler' and move with it to its rearward shuttle feeling position, one of the parters being fixed to the shuttle feeler and the other being actuated by lay movement to sever or part the filling as the lay moves toward its front position.
The present invention differs from such shuttle feeler thread parters in that the pi'esent invention provides two parting members each of which is Supported upon the shuttle feeler for movement relative thereto to part the filling thread. In carrying` the 3" invention into practical effect, one `of the parting members or blades is shown as pivotally Supported upon the shuttle feeler and provided with a heel to be struck by the lay as the latter moves frontwardly to give to the parter or blade its parting movement, vand associated with such parting member or blade is another parting member or blade also mounted on the feeler for movement in the performance of its cutting or parting function. In effecting movement of the two parting members or blades simultaneously to out or part the thread, one of them is actuated at the proper time, and preferably by lay movement, and connections are provided between the two parting members or blades Such that when the lay operated parter or blade is actuated, the other parter or blade will be Simultaneously actuated, so that the lling thread will be cut or parted by the combined action of the two parting mem` bers or blades.
It is now the usual practice to provide the shuttle feeler with some kind of a clamp, to clamp the end of the filling thread leading to the cloth Selvage and to carry the end 17, 1925. Serial No. 3,051.
frontwardly in order that the portion of such end adjacent the cloth selvage Shall be properly presented to the temple ithread cutter. In priorV constructions it has been the usual practice to` form the clamp as a part fixed tothe shuttle feeler andsometimes to clamp the end of the thread between such stationary clamping member and a movable thread parter or blade. In accord ance with the present invention, the clamping member is mounted on the shuttle feel# er for movement relatively thereto to clamp the end of the thread leading to the cloth selvage between itself and one of the threadparters or blades.V Such movement ofthe clamping member gives an increased hold on the end of the thread and `prevents its being withdrawn from the clamp as the shuttle feeler moves to front position.
The invention and new combination of parts will best be made clear from the following description and the Vaccompanying drawings of one good form thereof.
In the drawings:
Fig. l is a Side elevation of av shuttle `feeler provided with the present invention,"some of the loom parts beingomitted;
Fig. 2 is a detail of the thread parter showing the two members thereof as having been moved to cut or part the thread;
Fig. 3 is a top view partly in Section showing the pin and lslot connectionv between the two members of the parter and between one of the members of the and Fig. 4 is an enlarged front detail Showing the position "of the parts after the cutting operation.
The loom frame 1 may be of any usual or desired character and, as shown, has connected thereto a bracketlon which is pivotally mounted at 2 the shuttle feeler 3, the rearwardly extending end portion 4c of which is provided with an opening 5, as usual. Extending from the shuttle feeler is a lug or pin 6 which is engagedby the jaws 7, 8 which are actuated vfrom an indicating mechanism, (not shown) "for moving the shuttle feeler to its rearwardfshuttle feeling position when an indication has -been made for replenislnnentof fillingor other change in the loom opera-tion. y
The shuttle feeler issho'wn in the present instance as being guided in its movement towards and from the front of the loom by a parter and the clamp;
loo p end portion of the primary par-ter member 10 is the heel 12 which is adapted to be struck by the lay as it moves towards front position to actuate the parter members to part or cut the thread. In the present instance of the invention the lay 13 has a striking member or bun-ter 14 mounted thereon,
which is adapted to engage the heel 12 when the shuttle feeler is in its rearward shuttle feeling position and the parting members are open, as shown, to thereby eect movement of the parting members in their part ing or cutting operation. If desired, the primary parting member 10 may have a cutting edge 15.
Mounted upon the shuttle feeler '3 is the thread parter or blade 16 which may for identification be known as the secondary parter-member, and is here shown as provided with a large opening 17 through which passes the bolt 11 on which bolt the '"1 primary parter member is pivotally mounted. The secondary parter member 16 has a cutting edge 18 and is pivotally supported on a pin 19 extending laterally from 4the shuttle feeler 3 and passing through an .opening 2O formed in the primary parter member. The enlarged opening 17 which is formed fin the secondary parter member 16 permits movement of the secondary parter member about its pivotal support 19, and yet affords means for limiting such movement.
In accordance with the 'present invention, the two parter members 10 and 16 are to be moved relative to the shuttle feeler in the performance of their parting function, and as one means for effecting movement of the secondary parter member by movement of the primary partenmember, the latter is here shown as provided with a pin 21 eX- tending laterally thereof and engaging a recess .or opening 22 formed in the secondary parter member. The recessr 22 in the sec-I ondary parter member is formed on a vcurve which is eccentric to the pivotal axisof the primaryparter member 10 -or pin 11, the result being that when the primary parteil member is actuated by lay movement from the position indicated in Fig. 1 to that of Fig. 2, the pin 21 riding in the -eccentric slot 22 will effect simultaneous movement of the secondary partei' member,- so `that both parter members will partake of the move ment in their cutting function. In Fig. 1 the line a indicates a circular path concentric to the axis of the primary parter member 10 and it will be noted that the slot 22 is eccentric thereto.
In some cases it may be desirable to provide a clamp for holding or clamping the end of the filling thread leading to the cloth selvage, and as shown herein, such clamp may be formed by a clamping member 23 preferably mounted on the shuttl-e feeler at the side ofthe primary parting member 10, as indicated in Fig. 3. The clamping member 23 has an end portion 24 between which andl theside of the primary parter member 10 the thread b may be clamped, as indicated in Fig. 4. In the present instance vthe clamping member 23 is provided with the bifurcated end portion 25 which embraces the pin 19 on which the secondary parter member is pivoted, and the clamping member is provided with an opening 26-'similar yto the opening 22 formed in the secondary parter member and arranged eccentrically to the pivotal support of the primary parter member 10. Extending laterally from the primary parter member 10 is the pin 27, Fig. 3, which engages the eccentric opening 26 in the clamping member, and the clamping member 23 is also provided with an enlarged opening similar to th-e opening 17 formed in the secondary parter memberl and embracing the stud or pin 11, the construction being such that upon actuation of the primary parter member by lay movement, both the secondary parter member and the clamping member will be moved about their pivotal supports to cooperate with the primary parter m-ember to part the thread and clamp it between the primary parter member and ghe clamp-ing member 23, as indicated in The bolt 11 on which .the primary parter member 10 is pivoted and which alsopasses through the enlarged opening 17 of the secondary parter member and a similar opening in the clamping member 23, may be provided with a spring washer 28, as indicated in Fig. 3, for holding the parts in their assembled relation, as indicated. As shown` the primary parter member 10 is disposed between the secondary parter member 16 and the clamping member 23, but in accordance with the present invention, this particular relation of parts `may not always be necessary.
From the construction described as a goed practical form of the present invention, it
will be noted that the thread parter comprises two parter members or blades mounted upon the shuttle feeler for movement relatively thereto in the performance of the thread parting and cutting function, and that, as shown, such movement of the two Las-ases parter members or blades is efected by connections between the two which ltransmit movement of one of the parter members or blades to the other parter` member or blade.
As shown, also, the invention further comprises a clamping member which` is moved during the operation of the parting members to clamp the end of the filling between one of the parting members and the. movable clamp. v
The heel 12 of the primary parter member l0`is provided with a pin 29 whereby the primary parter member may be moved to its open position as the shuttle feeler is moved to its rearward shuttle feeling position, and, of course, simultaneously, the secondary parter member will be moved to its open position. Any suitable means may be employed for opening the members of the parter as the shuttle feeler moves to rearward position, but in the present instance of the invention, the bracket l has secured thereto at 30 the upstanding trip arm 3l on which is pivotally supported at 32 the trip 33 which may be of usual construction and adapted to operate upon the pin 29 of the primary member, as the shuttle feeler moves to rearward position to open the parter members as the pin 29 rides along` the inclined surface 34 of the trip. When the two movable parter members have been closed upon each other to part the thread and the shuttle feeler is moved to its front position, the pin 29 will ride under the trip 33, lift the same, and then pass frontwardly thereof, the parter members still remaining closed and the clamping member still remaining in its holding or clamping relation with one of the parter members. As the shuttle feeler moves to its rearward feeling position, the pin 29 will effect opening movement of the parting members and also of the clamp. The trip 33, as shown, has a stop 35 which is adapted to engage a stop 36 on the upstanding arm 3l to limit backward swinging movement of the trip.
Vhat is claimed is:
