THREAD-PARTING MECHANISM FOR LOOMS.

To all whom it may concern:

Be it known that I, ALoNzo E. RHOADES, a citizen of the United States, and resident of Hopedale, county of ll orcester, State of Massachusetts, have invented an Improvement in Thread Parting Mechanism for Looms, of which the following description, in connection with the accompanying drawing, is a specification, like characters on the drawing representing like parts.

This invention relates to looms of the feeler type, so -called, provided with means to cut the old or spent filling between the cloth and the shuttle when the running filling has been replenished prior to complete exhaustion, the parting or cutting means being usually mounted on a swinging arm which serves also as a shuttle-feeler.

Ordinarily, if the shuttle is improperly boxed for replenishment the shuttle-feeler performs its proper function, and by engagement with the shuttle not only prevents the operation of the replenishing mechanism but also holds the parting mechanism in in- 0 erative position. Sometimes, however, a ter the shuttle feeler has prevented replenishment of filling it will move back far enough to permit the parting means to part the filling, making a fault in the cloth, for if there is no replenishment the old filling should not be cut. This faulty action of the parts is due to various causes, such as slight movement of the shuttle into the box after the original engagement with the shuttlefeeler, to some slight lateral spring or play of the latter, etc., and my present invention has for its object the production of novel means for eflectually preventing cutting of the old filling if filling replenishment is not effected.

The novel features of my invention, as contained in one practical embodiment thereof, will be fully described in the subjoined s ecification and particularly pointed out in t 1e following claims.

Figurel is a transverse section of a portion of an automatic filling-replenishing loom having one embodiment of my invention applied thereto, the parts being shown in normal position; Fig. 2 is a top plan view of a portion of the apparatus illustrated in Fig. 1,

lg. 3 is a cross-sectional detail on the line 33, Fig. 4, looking toward the right, showing the parting means and other portions of Specification of Letters Patent.

the apparatus in position ust ready to operate if the shuttle is properly boxed; Fig. 4 is a top plan view of the parts shown in Fig. 3; Fig. 5 is a view similar to Fig. 3, but showing the lay at front center, and the parting means as having operated to part the old filling, the shuttle being properly boxed.

I have herein illustrated my invention in connection with a loom having threadarting means substantially as illustrated in nited States Patent to Draper, No. 683,423, dated September 24, 1901.

Referring to Figs. 1 and 2, the lay A, the feeder F to hold the filling-carriers or bobbins b, the transferror f fulcrumed at f, Fig. 1, the controlling rock-shaft (Z turned in the direction of arrow cZ when the replenishing mechanism is to be operated, the notched dog m operatively connected with the transferrer, and the hunter O on the lay to at times cooperate with the dog, may be and are all as in said patent. So, too, the swinging member or arm Y rearwardly bent at its upper end and having its hub y fulcrumed on the stud a to rock thereon and also to move laterally thereon, the stud y on said arm Y, having an attached finger a to control tlte rotative movement of dog m on its support, the arm (Z fast on rock-shaft d and bearing on the pin 30 on the arm Y, and the spring S Fig. 1, to normally maintain said arm and the parts carried thereby, and the dog m in normal inoperative position, as illustrated in Figs. 1 and 2, may be and are as in the Draper patent above. In said patent the upper end of the arm Y constitutes a shuttlefee er and it is notched at 1 to receive the spent filling when such notched end is moved across the lay adjacent the mouth of the shuttle-box B but while I notch the end of said arm it is not a shuttle-feeler, but serves as a carrier or swinging support for a device to part the spent filling, and comprising a fixed cutting blade 0, and a movable cutting blade c pivotally mounted at 0 on said arm and having a depending heel c, with a setting pin 0, the parting device being herein shown substantially as in the Draper patent.

The setting or opening of the blade is effected by cooperation of the pin 0 with a part of the thread-catcher, indicated at C, substantially as in said patent, and the blades are operated by engagement of the heel c with an actuator 2, herein shown as a projection forming a part of the bunter casting C which is rigidly secured to the front of the lay.

When filling replenishment is called for the rock shaft (1 is turned in the direction of arrow (V, Fig. 1, lifting the arm (Z and permitting the bent arm or member Y to swing rearward, and if no obstacle is met the full movement of the said member is completed, so that the thread-parter will be operatively positioned, as shown in Fig. 5, and the actuator 2 will engage the heel cof the movable blade 0 and closing it to cut the filling. This op eration will be readily understood, as it is substantially the same as set forth in Draper, before mentioned, and it will also be manifest that if the rearward movement of the swinging member Y is arrested not only will the actuator 2 be held from cooperating with the parting device but the dog m will be prevented from cooperating with the bunter C and there will be no actuation of the replenishing mechanism.

In my present invention the casting O is provided with forwardly extended bearings 3, 3, Fig. 2, for a short rock-shaft 4 on which is fixedly secured an upturned and rearwardly bent arm 5 terminating in a toe 6, and constituting the shuttle-feeler, its nor mal position being shown in Fig. 1, the feeler being movable in a ath adjacent the mouth of the replenishing sauttle-box B as clearly shown in Fig. 2.

A spring 7, Figs. 2 and 4, attached at one end to the rock-shaft 4 and at its other end to one of the bearings 3 is so wound about the rock-shaft as to normally retract the feeler and bring a stop 8 thereon against the bunter casting, with the forward edge 9 of the feeler arm in upright position in the path of a lateral projection, shown as a pin 10, on the swinging member or carrier Y. When filling replenishment is called for, as by the operation of any well known filling-exhaustion-indicating mechanism, and the rockshaft d is turned, the carrier Y swings rearward toward the advancing lay, and the pin 10 meets the edge 9 of the feeler arm 5 and swings the latter to move the tip 6 downward across the mouth of the shuttle-box to the shuttle race on the lay. If the shuttle S is properly positioned there is no opposition to this feeling movement of the shuttlefeeler, and as it completes its movement, as shown in Fig. 5, the carrier Y completes its full movement, so that the operatively positioned thread-parter is operated by the actuator 2, the spent filling is cut, and a fresh bobbin is transferred to the shuttle, after which the parts return to normal position Figs. 1 and 2, the spring 4 retracting the shuttle-feeler. Suppose, however, that the shuttle is improperly boxed, and its inner end projects into the path of the tip of the feeler, as in Fig. 4. Then the feeling movement of the feeler is arrested positively by engagement of its tip 6 with the shuttle, and the rearward movement of the carrier Y is arrested, as thc edge 9 then acts as a stop for the pin 10, so that the carrier cannot complete its full movement and the dog m is maintained inoperative. There will be no filling replenishment, and the old filling should not be parted, nor can it be, because the arrest of the carrier Y prevents the heel c from coming into engagement with the actuator 2, as clearly shown in Fig. 3, and as the lay completes its forward beat there will be no change in the relative position of the parts from that illustrated in Fig. 3. Owing to the short radius of the shuttlefeeler, and its path of movement, there is practically no chance for it to push the shuttle into the box or to slip past the tip of the shuttle, hence any engagement of the feeler and shuttle will prevent both filling replenishment and parting of the spent filling. It might happen that the shuttle-feeler would stick, so that its spring 4 could not retract it upon return of the carrier Y to normal position, and I have provided a positive retracting device for the feeler, to act should the spring be insufiicient. For this purpose the feeler-arm 5 has a laterally extended lug 11 which overhangs a V-shaped cam 12 secured to the carrier Y, the rearward movement of the latter causing the cam to move under and back of the lug 11 before the feeler movement is completed, but when such movement is completed, as in Fig. 5, the cam is under, back of and close to the lug. Now when the carrier Y moves forward again to normal position the cam acts upon the lug and starts the retraction of the feeler, so that the spring 4 can easily complete the retraction.

I have shown herein one practical embodiment of my invention, but various changes or modifications in details of construction and arrangement may be made by those skilled in the art without departing from the spirit and scope of my invention as set forth in the annexed claims.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent is:

1. An automatic filling-replenishing loom in which the filling is replenished before complete exhaustion having, in combination, a device to part the spent filling, a swinging support for said device, movable rearwardly to at times operatively position the parting device, a shuttle-feeler mounted on and movable relatively to the lay, anc means to effect feeling movement of the shuttle-feeler by rearward movement of said support, arrest of the feeler by engagement with the shuttle stopping the rearward movement of the support and acting therethrough to prevent filling replenishment and to maintain the parting device inoperative.

2. An automatic filling-replenishing loom in which the filling is replenished before complete exhaustion having, in combination, a

device to part the spent feeling, an actuator therefor carried by the lay, a shuttle-feeler mounted on the lay, and means to effect feeling movement of said feeler when filling replenishment is called for, arrest of the feeler by engagement with the shuttle acting to prevent cooperation of the parting device and its actuator.

3. An automatic filling-replenishing loom in which the filling is replenished before complete exhaustion having, in combination, a device to part the spent filling, an actuator therefor carried by the lay, a shuttle-feelcr mounted on the lay, and normally quiescent means cooperating with and causing feeling movement of the feeler when filling replenishment is called for, arrest of the feeler by engagement with the shuttle acting through said means to prevent filling replenishment and also to prevent cooperation of the parting device and its actuator.

4. An automatic filling-replenishing loom in which the filling is replenished before complete exhaustion having, in combination, a device to part the spent filling, an actuator therefor fixedly mounted on the lay, a shuttle-feeler pivotally mounted on the lay, and means operating when filling replenishment is called for to operate the shuttlefeeler and position the parting device for cooperation with its actuator, the shuttle when improperly boxed arresting the movement of the said feeler and acting through said means to prevent cooperation of the.

parting device and its actuator.

5. An automatic filling-replenishing loom in which the filling is replenished before complete exhaustion having, in combination, means, including a swinging member, to bring the filling-replenishing mechanism into action when the shuttle is properly boxed, a device on said member to part the spent filling, a shuttle-feeler operatively moved by the swinging member to feel for the shuttle, engagement of the latter by the feeler shortening the swing of said member and thereby preventing filling replenishment, and an actuator for the parting device, cooperating therewith only when the shuttle-feeler permits the full swing of said swinging member.

6. In a loom, filling-replenishing mechanism, means to control the operation thereof, including a member adapted to move across the mouth of the shuttle-box when the shuttle is properly boxed, a device on said member to part the old filling, a normally inoperative feeler actuated by movement of said member, to feel for the shuttle, engagement of the latter by the feeler arresting the n'iovement of said member and thereby preventing action of the replenishment umchanism, and an actuator for the parting de ice, mounted on a moving part of the loom, cooperation of said device and its actuator being effected only when unimpeded movement or said member is permitted.

7. In a loom, in'combination, a lay, mechani to replenish automatically the filling before complete exhaustion, a thrcad-parter movable automatically into position to part the spent filling, an actuator on the lay, to operate said thrcad-partcr, and means governed as to its position by the shuttle and mounted on the lay to arrest the movement of the thread-parter into cooperation with the actuator when the shuttle is improperly positioned, whereby operation of the thread-parter is prevented.

S. In a loom, in combination, i'nechanism to replenish automatically the running filling means, includin a buntcr on the lay and a dog to cooperate therewith, to effect the operation of said mechanism, a carrier operatively connected with and controlling said dog, a device on the carrier to part the spent filling at the replenishing side of the loom, an actuator for said device, mounted on the lay, and a shuttle-feeler independent of the carrier and adapted to cooperate therewith and maintain the dog and the parting device inoperative when the shuttle is improperly positioned for replenishment.

9. The combination, in a loom having mechanism to replenish the filling before complete exhaustion, of a lay, a shuttlefeeler mounted thereon and norn'ially inoperative, and means to effect feeling movement of the feeler when replenishment is called for, arrest of the feelcr by an improperly positioned shuttle acting through said means to prevent replenishment of filling.

10. The combination, in a loom having mechanism to replenish the filling before complete exhaustion, of a lay, a springretracted shuttle-fceler pivotally mounted on the lay, means to control the operation of the replenishing mechanism, including a pivotally mounted member movable toward the lay when replenishment is called for, and a projection on said member to engage and effect operative movement of the shuttlefeeler at such time, arrest of the feeler by the shuttle when improperly positioned acting through said member to prevent filling replenishment.

11. The combination, in a loom having merhanism to replenish the filling before complete exhaustion, of a lay, a springretracted shuttle-feelcr pivotally mounted on the lay, means to control the operation of the replenishing mechanism, including a pivotally mounted member movable toward the lay when replenishment is called for, a projection on said member to engage and effect feeling movement of the shuttlefeeler at such time, a thread-cutter on said member and operatively positioned only when the full movement or" the member is effected, and an actuator for the threadcutter, mounted on the lay, the shuttle when improperly positioned arresting the shuttle feeler and thereby preventing full movement of the pivoted member, to thereby prevent cooperation of the thread-cutter and its actuator and also to prevent filling replenishment.

12. In a loom, in combination, mechanism to replenish automatically the running filling, a lay, a shuttle-feeler, a thread-parter mounted independently thereof and movable into and out of operative position, to part the spent filling at the replenishing side of the loom, an actuator for the threadparter, carried by the lay, and a movable member to effect feeling movement of the feeler and also governed by the latter to prevent the operation of the replenishing mechanism when the feeler engages the shuttle, the thread-parter being carried by said member and held from cooperation with its actuator when the shuttle is engaged by the shuttle-feele11 13. In a loom having mechanism to replenish automatically the running filling, means to control the operation of such mechanism, including a swinging member movable rearwardly when replenishment is called for, the lay, a shuttle-feeler pivotally mounted thereon, a spring to retract it, means whereby rearward movement of said swinging member efiects feeling movement of the shuttle-feeler, and positively-acting means to effect retracting movement of the feeler as the swinging member returns to normal position.

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
