Abstract:
A method and apparatus for applying travelers to a ring of a fiber processing machine. A traveler applicator includes a traveler rail on which travelers are urged by a pusher towards a reciprocating traveler tooth. Actuation of a trigger causes the traveler tooth to engage a traveler from the traveler rail and to advance it outwardly for attachment to a ring. Release of the trigger causes the tooth to retract and allows clearance between the tooth and the next traveler positioned on the traveler rail for dispensing. Upon full retraction of the tooth, the tooth advances inwardly to engage the next traveler on the traveler rail. A spring-biased engagement member contacts the traveler to secure it on the tooth. A cartridge having a plurality of traveler-holding rails about its periphery feeds travelers to the traveler rail. Once a cartridge rail is depleted of travelers, the cartridge is rotated such that the next rail having travelers is presented to the traveler rail for dispensing.

Description:
BACKGROUND OF THE INVENTION 
     This invention relates generally to a device and method of applying travelers to rings of ring spinning machines and twisting machines. 
     Travelers are commonly used on rings found in ring spinning machines and twisting machines. A typical traveler design includes a C-shaped metal clip which attaches to the ring for sliding movement around the ring. Bands of fibers having little twist, known as roving, or no twist, known as sliver, pass through the drafting zones of a spinning machine and twist is placed in the fibers after they depart the final drafting zone. 
     Yarn is formed by twisting fibers exiting the drafting system with the combined rotation of the bobbin and traveler. 
     The traveler rotates on the ring and serves as (1) a guide for yarn to the bobbin; and (2) a brake to control yarn tension. 
     Because the traveler and the rings on which the travelers ride are typically metal, the metal interface between the traveler and ring causes wear, primarily in the travelers. After a period of time, when the travelers become too worn, they must be replaced. 
     Replacement of travelers on the rings is generally performed by hand. Because of the relatively small size and light weight of the individual travelers, applying the travelers one by one to individual rings can be a time-consuming and tedious endeavor. In an attempt to expedite this procedure, several devices have been patented for dispensing travelers. 
     For example, U.S. Pat. No. 2,749,601, issued to Rouillon, discloses a pistol-shaped device into which a magazine of travelers is fed laterally. A tongue is used to advance an individual traveler from the magazine outwardly towards a spinning ring. Ultimately, through interaction with a feed head provided on the device, the traveler is placed onto the ring. U.S. Pat. No. 2,953,845, issued Ramseier, also discloses a device where travelers are fed in laterally. The travelers move along a guide rod, and adjustment means are provided for travelers of different sizes, through use of an eccentric pin. Further, U.S. Pat. No. 4,575,933 issued to Neff, discloses a device where ring travelers are supplied on a flexible magazine strip and are transferred to a magazine bar by pulling at the magazine strip in a pre-determined location. The magazine bar is bent off at one end and is tapered in order to form a hook for temporarily holding a traveler prior to placement on a ring. 
     Other devices have also been patented for dispensing small items, such as U.S. Pat. Nos. 2,222,125, issued to Stehlik, and 3,353,736, issued to Bauer, which each disclose devices having cartridges with holding cells that are individually exhausted in succession. The Bauer device carries drapery hooks, and the Stehlik device carries nails. U.S. Pat. No. 2,931,038, issued to Wandel, discloses cartridges of staples wherein layers of staples are used in succession. 
     While the foregoing designs are known, there still exists a need for quick and easy-to-use system for inserting a supply of travelers into an applicator and for applying the travelers to the ring of a textile fiber processing machine. 
     SUMMARY OF THE INVENTION 
     It is, therefore, the principal object of this invention to provide a traveler application system which provides for easy loading of travelers into a traveler applicator and expedited placement of travelers onto spinning and twisting rings. 
     It is another object of this invention to provide a cartridge loaded with travelers which can be inserted into a traveler applicator. 
     It is yet another object of the present invention to provide an expendable cartridge carrying multiple rows of travelers for use in a traveler application device. 
     Yet another object of the present invention is to provide a method of replenishing travelers in a traveler applicator. 
     A still further object of the present invention is to provide a method of dispensing a traveler and attaching the traveler on a ring. 
     Generally, the present invention includes a device for applying a traveler to a ring of a textile ring spinning machine, the device includes a body member having a first end and a second end opposite the first end. The body member defines a traveler receiving compartment, open to the first and second ends of the body member. 
     A cartridge member is carried in the traveler receiving compartment, and the cartridge member defines a longitudinal axis, and is rotatable about the longitudinal axis within the traveler receiving compartment. The cartridge member has plurality of cartridge rails, each of the cartridge rails being adapted for carrying a plurality of travelers thereon. 
     A transport rail is provided having a first end next to one of the cartridge rails and a second end next to the second end of the body member. A spring-biased pusher is carried next to one of the cartridge rails for urging a traveler from the cartridge rail towards the second end of the transport rail. A tooth is provided which is movable between a retracted position and an extended position, and between a clearance position and an engagement position. The tooth is adapted to engage a traveler on the second end of the transport rail when in the retracted and engagement positions, and for placement of a traveler on a ring of a ring-spinning machine when in the extended position. 
     An indexing mechanism may also be provided for indexing the cartridge within the traveler applicator to sequentially present each of the cartridge rails of travelers to the transport rail one rail at a time. 
     The present invention also includes a method of applying travelers to a ring of a textile processing machine with the present traveler applicator device, including providing a traveler applicator having a transport rail for carrying a plurality of travelers and providing a cartridge adjacent to the transport rail, wherein the cartridge has a plurality of rails each carrying a plurality of travelers. Then, a traveler from at least one of the cartridge rails is transferred to the transport rail. The traveler transferred to the transport rail from the cartridge is then pushed to the end of the transport rail, and a moveable tooth is provided for engaging the traveler at the end of the transport rail. The traveler is removed from the end of the transport rail with the moveable tooth, and the traveler is moved outwardly from the transport rail with the moveable tooth. Finally, the traveler is applied from the moveable tooth onto the ring of the fiber processing machine.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     The accompanying drawings and the description which follows set forth this invention in its preferred embodiment. However, it is contemplated that persons generally familiar with travelers and ring spinning will be able to apply the novel characteristics of the structures illustrated and described herein in other contexts by modification of certain details. Accordingly, the drawings and description are not to be taken as restrictive on the scope of this invention, but are to be understood as broad and general teachings. 
     Referring now to the drawings, wherein like reference characters represent like elements or features throughout the various views, the traveler application system of the present invention is indicated generally in the figures by reference character 10. To provide an overview, traveler applicator 10 is illustrated in FIG. 1 having an elongated body, or handle, member, generally A, which lends itself to being carried in the hand of a user (not shown). Extending outwardly from body member B is a moveable trigger B. Briefly, trigger B is used to advance a traveler T outwardly from handle member A for ultimately applying the traveler T to a ring R, shown in FIG. 9. 
     Handle member A defines a traveler receiving compartment, generally C therein, as can be seen in FIGS. 2 through 4C. A transport rail D is carried within traveler receiving compartment C and allows travelers T to be slidingly carried thereon in a side-by-side relationship. A spring-biased pusher E is also carried by body member B, and as illustrated in FIG. 3, urges travelers along transport rail D towards the terminus F of transport rail D. At terminus F, a tooth G carried by a transfer assembly H picks up a traveler T, and through squeezing of trigger B, transfer assembly H carries the traveler T outwardly for attachment to a ring R, as illustrated in FIGS. 8 and 9, and FIG. 14B. 
     Transfer assembly H moves outwardly upon squeezing of trigger B, and reciprocates inwardly upon release of trigger B. While transfer assembly H reciprocates, a transfer block assembly I blocks the next traveler T at terminus F from further movement, until tooth G is retracted back into position for engaging that next traveler T and advanced outwardly. 
     A cartridge J is provided within traveler receiving compartment C for carrying a supply of travelers T. The travelers T are carried in a side-by-side relationship on individual cartridge rails K spaced about the periphery of cartridge J. Pusher E engages the rearwardmost traveler T on a particular cartridge rail K and, upon alignment of that cartridge rail K with transfer rail D, pushes that traveler, and all the travelers between it and terminus F towards terminus F. Once all of the travelers T have been exhausted from that particular cartridge rail, a cartridge indexing mechanism L is actuated to rotate cartridge J such that a cartridge rail K having travelers T thereon is brought into alignment with transfer rail D, for allowing continued traveler T dispensing. 
     An adjustment mechanism M is also provided, as illustrated in FIGS. 2 and 13, wherein a traveler T is inserted within a recess N for allowing proper adjustment of traveler applicator 10 for travelers T of different sizes. 
     In a preferred embodiment, traveler applicator 10 includes handle member A, being constructed of two halves, generally 12, 14, which are attached to one another with generally 16, or other similar fasteners. Although body member A is illustrated as being comprised of two halves 12, 14, it is to be understood that it could be constructed of more pieces, or it could be of unitary construction, if desired. 
     Pivotally connected to handle member A is trigger B. Handle number A is sized such that a user would be able to hold traveler applicator 10 in the palm of his or her hand and to actuate trigger B with the fingers of the same hand. Preferably, the handle A extends downwardly at an angle between 5 and 10 degrees from horizontal, and preferably, at approximately 6 degrees during use to aid in the comfort to the user during operation. Trigger B actuates transfer assembly H and serves to reciprocate transfer assembly H to and fro between an extended position, as illustrated in FIGS. 9 and 10, and a retracted position, as illustrated in FIG. 8 and 12. Since tooth G is provided on an end of transfer assembly H, tooth G likewise moves between retracted and extended positions, as illustrated in FIGS. 8 and 9, respectively. Trigger B may include a slot 20 for receipt of finger 22 of pusher E, which extends outwardly from handle member A, when trigger B is depressed. Together, halves 12, 14 define traveler receiving compartment C. Compartment C extends from a first open end 23 to a second open end 25 opposite first end 23. Ends 23, 25 correspond to the ends of body member A. Body member A defines access windows 27, 29 for allowing a user to peer into compartment C and to potentially make adjustment through such windows 27, 29 for items carried therein. 
     Transport rail D is attached inside compartment C and extends longitudinally therein. Fasteners, generally 24, such as screws are used to connect one end 26 of transport rail D to handle portion 14, and the second end 28 of transport rail D is attached to a receiver block 30 by fasteners, generally 32, such as screws. Receiver block 30 is spring-mounted to lo handle portion 14 through the use of pins, generally 34, which pass through coil springs, generally 36, interposed between one face of receiver block 30 and an interior portion of handle portion 14. The spring-mounting of receiver 30 works in conjunction with cartridge indexing mechanism L to allow for adjustment of traveler block 40 with respect to transfer assembly H and traveler block assembly I. This adjustment feature allows for applicator 10 to be used for dispensing various sizes of travelers T. 
     Transport rail D is of a cross-sectional profile to allow the generally C-shaped travelers T to slide therealong while being retained on a rail D. The cross-sectional profile of transport rail D is similar to that of the cross-sectional profile of a cartridge rail K. Travelers are supplied from cartridge J to free end 42 of transport rail D and are pushed therealong in a stacked, side-by-side relationship, by pusher E. 
     Pusher E is illustrated in FIGS. 2, 3, and 4A through 4C. Pusher E is connected to a post 44 of handle portion 14 via a coil spring 46. Pusher E is moveable along cartridge J, through interaction of finger 22 in a slot 20 defined at intersection of handle portions 12 and 14. 
     FIG. 3 illustrates pusher E at approximately midway along the slot 20. As can be seen from that figure, pusher E bears against the rightmost extreme traveler T on the particular rail K of cartridge J. The spring force of pusher E against that traveler, forces all the travelers to the left of that traveler to be urged towards terminus F of transport rail D. 
     FIG. 4A illustrates pusher E at approximately the leftmost extent of its travel within slot 20, which occurs when a particular rail K, in this instance rail 50, is depleted of travelers. Cartridge J is indexed by rotating it about its longitudinal axis 52 through use of a cartridge index mechanism L. In so doing pusher E is moved to the rightmost extent within slot 20 such that the profiled head 54 of pusher E, which corresponds to the cross-sectional shape of rails K, clears the rightmost end 56 of cartridge D. This allow cartridge D to be rotated with knob 58 such that a new, traveler-loaded rail, 60, is in alignment with free end 42 transport rail D. A cartridge washer 62 is provided at the leftmost end 64 of cartridge J and defines a slot 66 therein. Washer 62 remains stationary as cartridge J turns such that slot 62 remains in communication with free end 66 of transport rail D. Washer 62 serves to prevent travelers from other rails K from falling into the interface between the end of cartridge J and diaphragm member 68, which generally divides compartment C into a traveler rail section to the left of member 68 and a cartridge section to the right. Once cartridge J has been rotated to the position as shown in FIG. 4B, pusher E is moveable to contact the rightmost traveler on that rail 70, as seen in FIG. 4C. 
     While pusher E is in the rightmost position within slot 20, it is held between the right end of cartridge J and retainer 72 through engagement of head 54, to allow cartridge J to be indexed from the position shown in FIG. 4A to the position shown in FIG. 4B. 
     The terminus F of transport rail D is approximately at a right angle with respect to the portion of the transport rail D onto which the travelers are initially loaded. The travelers pass around a curved portion 74 on the transport rail D. This allows for proper presentation and orientation of a traveler when it is subsequently picked up by tooth G and advanced forward by traveler assembly H. Transport rail D is undercut at terminus F to allow the open side of a C-shaped traveler to clear transport rail D, thereby allowing the traveler to be removed by the rectilinear movement of tooth G. 
     Tooth G is perhaps best illustrated in FIG. 11 and FIGS. 14A through 14G. Tooth G is attached adjacent to the nose portion of linkage member 76 of transfer assembly H. Linkage member 76 is carried for sliding movement with respect to stationary member 78 and is connected for pivotal movement via pin 80 to a second linkage member 82, which in turn is connected for pivotal movement by a pin 84 to a third linkage member 86. Third link member 86 is fixedly attached to trigger B and moves corresponding to movement to trigger B about pin 88. A torsion spring 89 encircles pin 88, and is connected to trigger B to urge trigger B to its released position. 
     Turning to FIG. 8, trigger B is shown in its released position. In this position, linkage, or transport, member 76 is in a retracted position, as is also tooth G. Upon squeezing of trigger B towards handle portion 14, linkage member 86 moves forward, causing a corresponding movement of linkage member 82, and, in turn, a corresponding forward advancement of transport member 76. This causes tooth G to pull the leading traveler outwardly from rail tongue 89, illustrated in FIGS. 16A and 16B, of terminus F of transport rail D and to move it linearly forward with the advancement of transport member 76. Rail tongue 89 is undercut such that a traveler T can be moved laterally thereon for stripping a traveler T from transport rail D. The undercut shape of rail tongue 89 thus allows tooth G to advance a traveler outwardly from transport rail D as tooth G moves forward. This traveler T is secured to tooth G by a spring clip 90 within a recess 91, illustrated more clearly in FIGS. 14A and 14B. Shearing edge 95, which serves to define recess 91, acts in cooperation with tooth G to shear the endmost traveler from rail tongue 89 as tooth G advances. Recess 91 acts as a traveler compartment for receiving a traveler sheared from transport rail D, and, through contact of spring clip 90, traveler T is retained in recess 91 as transport member 76 advances. Further depression of trigger B causes transport member to move to its furthermost outward, or extended, position, such as illustrated in FIG. 9, where the traveler can be snapped onto the ridge 92 of a ring R. A tongue 93 is connected to receiver 30 to aid in retaining a traveler on tooth G as tooth G moves to its extended position, carrying the traveler. 
     Upon release of trigger B, transport member 76 moves rearwardly as illustrated in FIG. 14G. As transport member 76 moves rearwardly, a pivoting member 94, to which tooth G is attached, engages with a first wedge member 96 to pivot member 94 outwardly away from transport member 76, and to also, correspondingly, move tooth G outwardly away from terminus F of transport rail D to a clearance position. This allows tooth G to &#34;step over&#34; the closed back portion of the traveler waiting at terminus F. As the transport member 76 continues to move rearwardly, upon release of trigger B, a downwardly extending wedge flange 98 of pivotal member 94 clears wedge 96, and pivotal member 94 moves from its clearance position, illustrated in FIG. 14G, to its engagement position, such as illustrated in FIG. 14F. Pivoting member 94 is connected to transport number 76 by means of a pin 100. A leaf spring member 102 is attached to a block 104 through which pin 100 passes, and leaf spring 102 contacts the face of pivoting member 94 to continually urge pivoting member 94 towards its engagement position. FIG. 11 illustrates pivoting member 94 moving towards its clearance position, wherein tooth G clears the next traveler at terminus F prior to snapping back in place in the central opening of that traveler. FIG. 12 illustrates tooth G in its engagement position engaging with the next traveler at terminus F. 
     As transport member 76 retracts, a curved portion 106 of spring 90 engages with a bar 108, which causes a lifting of spring member 90. This allows tooth G to securely seat within the central opening of the next traveler waiting at terminus F. Upon forward advancement of transport member 76, the curved portion 106 of spring 90 disengages with bar 108, which causes spring member 90 to move downwardly such that a flange portion 110 of spring member 90 engages the top portion of the traveler pulled out by tooth G as transport number 70 advances, as shown in FIG. 14B. 
     Traveler block assembly I works in conjunction with transport assembly H to help prevent the next traveler from leaving terminus F until that traveler is actually physically transported by tooth G. As illustrated in FIGS. 14C through 14G, as transport member 76 advances, traveler block 40 is moved outwardly through interaction of wedge flange 98 carried on the underside of transport member 76, acting in conjunction with the backside of wedge 40 carried upon traveler block 40. This causes the traveler block 40 to release the next traveler such that tooth G can extract the traveler and carry it forward. Once tooth G has moved a sufficient distance in carrying the next traveler away from terminus F, traveler block 40 snaps back into place for blocking the next traveler from further movement at terminus F. A traveler plate 112, connected to traveler block 40 makes actual contact the next traveler for blocking it from further movement. Traveler block 40 is slidable on shaft 114, but is urged towards its blocking position by a coil spring 116 carried on shaft 114. 
     Cartridge J includes a plurality of cartridge rails K provided thereon. Although seven cartridge rails K are illustrated in the drawings, it is to be understood that more or less rails K could be provided on cartridge J, depending on the particular travelers loaded on cartridge J the size of such travelers, the shape of such travelers, etc. Cartridge J, in the preferred embodiment, includes a portion 118 on its periphery where no rail K is provided. This allows for pusher head 54 of pusher E to be moved to it rearwardmost position, such as shown in FIG. 4B, without engaging a rail K after a cartridge J has been loaded into compartment C. Cartridge J would then be indexed such that the rightmost end of the next rail would be engagable by pusher E, as illustrated in FIG. 4C. Cartridge J is provided with rails of a cross-sectional shape which allow for the same cartridge to be used for a variety of different types of travelers. Cartridge J can be reusable, or, could be made relatively inexpensively so that it could be discarded after its traveler supply was exhausted. Cartridge J includes washer 62 provided thereon. Washer 62 is, as discussed above, rotatable with respect to cartridge J such that cartridge J can be indexed once carried in compartment C, while washer 62 remains stationary. 
     Cartridge indexing mechanism L includes an elongated shaft 120 having a tip portion 122 which is inserted through a longitudinal bore 124 provided in cartridge J. A spring 126 is provided on shaft 120 to bear against end 56 of cartridge J when shaft 120 is inserted through bore 124 of cartridge J. Preferably, both shaft 120 and bore 124 of cartridge J have cooperating cross-sectional profiles, such as the hexagonal profile illustrated in FIGS. 5 through 7. This allows shaft 120 to be rotated by knob 58 for causing corresponding rotation of cartridge J. Coil spring 126 on shaft 120 urges cartridge J towards transport rail D once cartridge J has been inserted through the rear opening 128 of handle member A. 
     Retainer member 72 is also provided on shaft 120 and includes a slot for allowing pusher head 54 of pusher E to slide into the interface between cartridge end 56 and retainer 72 when pusher head E is moved to its rightmost position, as illustrated in FIG. 4B. A notch 134 is provided in retainer number 72 for engaging with a raised rib 136 provided in portion 14 of handle A to properly align retainer member 72 with respect to cartridge J. A cap member 138 is provided on shaft 120 and is spaced from retainer 72 by a spacer member 140. Cap member 138 substantially closes off open end 128 of handle member A and is held in place by a threaded ring 142, which is threadingly connected to the threads 144 provided on the end 23 of handle member A. 
     Although not illustrated, instead of having longitudinally-extending rails K, cartridge J could include, although not shown, rails of other configurations. For example, rails could extend circumferentially or helically about cartridge J or could extend about cartridge J in some other curvilinear fashion. Additionally, although not shown, one single rail could be provided which would extend helically about the periphery of cartridge J in a manner similar to the thread on a screw. A longitudinally moveable member (not shown) could thus be provided which would be biased by a spring member or members (not shown) or biased in some other fashion to continually press on the group of travelers carried on such a helical rails or plurality thereof, for advancing such travelers towards the transport rail D. 
     Another feature of traveler applicator 10 is that it can be used for various sizes of travelers. In order to adjust the proper clearance between transfer assembly H, retaining block assembly I, tooth G and receiver 30, a threaded knob 146 is provided for threadingly engaging a shaft 148, as illustrated in FIG. 13, and a well 150 is provided for receipt of a particular traveler T of the style to be loaded in applicator 10. By tightening knob 146 against the traveler T, proper spacing, as indicated by arrows 147, of assemblies H and I and tooth G with respect to receiver 30 can be achieved for travelers of that particular type. 
     When inserting a cartridge of travelers into applicator 10, ring 142 is unscrewed, and the cartridge indexing mechanism L is removed. The new cartridge J is inserted into compartment C, and shaft 120 is inserted into cartridge bore 124, until the tip 122 of shaft 120 is received in a bore 152 in member 52. Cartridge J is rotated with knob 58 until pusher head 54 can pass down the open portion 118 of cartridge J. Once pusher E is at its rearwardmost position, cartridge J can be rotated such that a cartridge rail K full of travelers is in alignment with free end 42 of transport rail D. Pusher E can then be released such that pusher head 54 engages the rightmost traveler, as illustrated in FIG. 4C, on rail K to urge all the travelers on rail K and all of the travelers on transport rail D, toward terminus F of transport rail D. 
     As travelers are dispensed onto rings through actuation of trigger B, the cartridge J remains stationary. However, upon depletion of a rail of the cartridge, pusher E is moved to the position illustrated in FIG. 4B, and cartridge J is rotated such that a rail full of travelers is presented to pusher E. Then, pusher E is again allowed to push travelers from this new rail. Once all the rails of cartridge J are depleted of travelers, removal of cartridge J is accomplished in reverse order as it was installed, as discussed above. 
     In a preferred embodiment, portions 12, 14 of handle A are constructed of injected-molded plastic. It is to be understood, however, that other materials could be used instead, such as metal, wood, or the like. Also, various materials could be used to construct other portions of applicator 10 such as metal, plastic, etc. 
     From the foregoing it can be seen that traveler applicator 10 provides a handy traveler application device, and that the traveler cartridges J of the present invention allow for quick and easy replenishment of travelers to the applicator. 
     While preferred embodiments of the invention have been described using specific terms, such description is for present illustrative purposes only, and it is to be understood that changes and variations to such embodiments, including but not limited to the substitution of equivalent features or parts, and the reversal of various features thereof, may be practiced by those of ordinary skill in the art without departing from the spirit or scope of the following claims.
