APPARATUS FOR PACKING CONTAINERS WITH YARN E. G. KELLER -2 Sheets- Shet 2 Filed Nov. 17, 1938 INVENTOR Ernest G.

ATTORNEY Patented Dec. 8, 1942 UNITE STATES APPARATUS FOR PACKING CONTAINERS WITH YARN 2 Claims.

This invention relates to improvements in apparatus for packing the same with yarn.

One of the objects of this invention is to utilize, as a substitute for a spool or reel, a container within which yarn or thread is packed and completely enclosed to enable a better, more-ready and facile feed While preventing contamination thereof from outside sources, and avoiding deterioration of the yarn or thread.

Another object of my invention is to utilize a yarn container comprising a transparent capsule or cartridge composed of a shell of sheet material such as Celluloid or a condensation product which will encase and substantially shield the yarn from access of air and which will prevent deterioration of yarns that embody strands of rubber or the like.

Still another object of my invention is to utilize asubstantially-enclcsed capsule or cartridge having a relatively small head aperture to permit a direct filling movement of the yarn into the capsule or cartridge from a large bobbin and to provide for an outward feeding movement of such yarn when it is desired to use the material, as for example, in the shuttle of a sewing machine or the like;

Another object of my invention is to utilize a yarn or thread enclosing capsule or cartridge having at one end a hole or holes therein to cause packing of the thread within the capsule or cartridge by a fluid agent, as for example by exhausting air from one end of the capsule or cartridge by the operation of the sucking action of suction means to the thread or yarn enclosed in the capsule or cartridge or by forcing air into the capsule or cartridge through the opposite end during the filling operation thereof.

Another object of my invention is to utilize a capsule or cartridge having a head portion .provided with a relatively small strand-receivingand-guicling aperture.

Another object of my invention isto provide apparatus for packing yarn into enclosing capsules of the type hereinabove referred to, which will enable a maximum amount or yardage of yarn to be filled into a capsule.

Another object of my inventicnis to pack yarn within an enclosing container or capsule by applying suction to the bottom of the capsule to suck theyarn to the bottom .of the capsule during a feeding movement thereof through the top of the capsule.

Still another object of my invention is to pack yarn within an enclosing container .or capsule by applying'vibration to the bottom of the thepurpose of assisting in packing within the capsule yarn fed in at the head portion thereof.

With these and other objects in view, the invention comprises the combination of members and arrangement of parts so combined as to coact and co-operate with each other in the performance of the functions and the accomplishment' of the results herein contemplated, and

comprises in one of its adaptations the species or preferred form illustrated in the accompanying drawings, in which:

Fig. 19 is a top view of the capsule shown in Figs. 8 and 9.

Referring now to these drawings, which illustrate a preferred embodiment of my invention, 5 indicates a capsule which, in accordance with my invention, is filled withyarn or thread 6 and which, when so filled with yarn or thread, is useful for any purpose to which a spool or bobbin of thread or yarn may be put and which is particularly useful as a feeding device for thread or yarn in the shuttles of sewing machines and other machines in which it is desired to avoid 5 the sticking, jamming and tangling frequently encountered when yarn or thread is wound upon a spool or bobbin and then inserted in a shuttle. While the ease and facility of feeding is an important advantage procured by the use of my yarn-filled capsules, it will be obvious also that the enclosure of thread or yarn within a container of the type specified will retain the same in a condition free from contamination by outside sources and will also, when the thread con- 5 tains a strand of rubber or like material, prevent any deterioration of such rubber due to drying out from access of air thereto.

My invention therefore, contemplates the provision, of a yarn-enclosing capsule 5 and the filling of this capsule with yarn or thread 6 in such a manner as to completely fill the capsule so as to contain a sufiicient yardage of thread or yarn to enable the same to be used as a substitute for a spool, bobbin, or the like in the shuttle of a sewing machine or other machines in which shuttles are employed. In order to accomplish such filling and to utilize the space within the capsule to enclose a maximum yardage of material, I provide a filling machine having means for applying suction within the capsule to the yarn as it is filled through the top of the capsule to pack the same toward the bottom thereof and I also preferably provide, in combination with such suction means, additional means for providing a continuous hammering or percussion of the capsule against a table to cause the filled material to be more tightly packed within the capsule by a downward movement induced by such hammering or percussion.

In the accompanying drawings, I have shown one form of machine embodying the necessary mechanism for filling and packing a capsule with yarn in order to procure a maximum yardage within the same, and in such drawings, l indicates a base member on which is mounted upright frame members 2, 2'. At the front of the frame member 2, I attach a supportingbracket 3 within which is slidably mounted a capsule-mounting socket 4. Capsules 5 arerfg adapted to be successively mounted in the socket 4 and, as illustrated, each of the capsules is provided, at its upper end, with an aperture or head hole 5' through which a strand of yarn 6 is fed in the capsule by any suitable yarn-feeding 5 mechanism and preferably by yarn-feeding mechanism hereinafter described which will measure the yardage of yarn fed to the capsule and which, when a given yardage is supplied, will automatically stop the feed of the yarn to; ()0 the capsule.

In accordance with my invention, however, it is desirable to fill into a capsule of given dimensions, a maximum yardage of yarn and also to cause the laying within the capsule of the-{Z strands of yarn in such manner that the yarn may be readily and easily withdrawn from the capsule without tangling, sticking or jamming.

For the purpose hereinabove specified, I preferably provide a hollow capsule composed of Celluloid or other suitable material and comprising a body portion of substantially cylindrical conformation with a rounded head or top portion and completely closed except for the axially-disposed filling and feed aperture 5' hereinabove referred to. The capsule is mounted within the cylindrical socket 4, and has a bottom portion which, in mounted position, extends within the socket 4 and has an air-tight connection therewith, and said bottom portion has one or more and preferably a series of five suction apertures 5 to which suction is applied through the socket 4. In the preferred form of my invention the head and body of the capsule are formed in one piece and the bottom end is bent or turned around a flat disc having the suction apertures 5 hereinabove specified.

A substantially-closed capsule so mounted is, in accordance with my invention, completely filled with yarn and the yarn is packed therein in such a manner as to enclose, in the space provided within the capsule, a maximum yardage. In the preferred embodiment of my invention, I accomplished this object by applying suction to the bottom apertures 5 of the capsule through the socket 4 during the feeding operation of the yarn so as to continuously draw yarn being fed through the top thereof down toward the bottom of the same and, at the same time, I preferably provide means for hammering the capsule 5 and socket 4 against the top of the bracket 3.

In the preferred form of my invention, the socket 4 is, at its lower end, provided with a lateral bore 4' connected with a flexible suction tube 1 leading to a suitable suction pump P shown in Fig. 1.

My preferred form of hammer or percussionpacking mchanism comprises the mounting of the socket 4 on a rod 8 extending through a guide-bore 3 in the supporting bracket 3 and having its end 8 contacting with the peripheral surface of a hammering or percussion cam 9 mounted on a shaft l0 supported in bearing brackets ll below the socket-supporting member 3. The said rod 8 has mounted thereon, a spring l2 stretched between the bottom 3' of the supporting bracket 3 and a washer 8 on the rod 8 held in place thereon by pin 8 Said spring is intended to force end 8' under the rod 8 into continuous contact with the peripheral surface of the cam and to force the bottom of the flange 4 downward to impinge against the upper surface 3 of the supporting bracket 3. Upon a rotation of the cam 9, the rod 8 will be lifted to cause socket 4 to be raised above the surface It until the radial surface 9' is reached when the rod will abruptly be forced to move toward the axis of the cam by the spring l2 and during this movement the flange 4 will strike the upper surface 3 of the supporting bracket so as to provide a hammering or percussion effect, which will cause any yarn within the capsule to be moved by inertia toward the lower end thereof and thus to provide a percussion packing thereof within the capsule, it being understood that this percussion packing will supplement the packing obtained through the suction action hereinabove described.

When a given yardage is supplied to the capsule, further feeding of the yarn is discontinued to permit severing of the yarn and removal of the container, and I therefore utilize, in combination with rotatable feed rollers l5, 16, between which the yarn is guided, means for applying suitable pressure to one of the feed rollers and, as illustrated, pressure is applied to the roller [6 to press it against the rotating roller l5 and to cause a feeding movement of the yarn 6 through funnel l7 and down into the container or capsule 5. As

shown, the feed roller I is mounted to rotate about a fixed shaft l5 supported in suitable bearings integral with the frame and is rotated through a pulley |5= connected by belt It with pulley l5 rotated by motor l5 The feed roller l6, which applies pressure to the yarn is mounted on an axle l6 fixed in a tiltable frame It which is adapted, when a given yardage is supplied, to cause the lifting of the pressure roller 16 and thus to stop further feeding of the yarn. As illustrated, the roller 16 has connected thereto and rotates a gear l6 which meshes with and rotates a gear [9 fast on a shaft 28 and which, in turn, rotates a worm 2| also on shaft 20. The worm 2i meshes with and rotates a worm-wheel 22 and shaft 23 which rotates a trip-member 23 provided with an adjustable pin 23 adapted, upon a complete turn of the member 23' to engage a tilting lever 24 mounted on a pivot member 25 supported in suitable bearings and adapted, upon tilting by the lever 24, to cause a toe 25 to engage and tilt the table or plate 21 upwardly, the tilting toe 26 being normally held in its lowermost position out of contact with plate 21 by the weight 26'. The tilting of the plate releases a connected detent 28 from the notch 29 in a slidable arm 29 which is mounted to slide transversely of the frame of the machine in cleats 29 29. Upon release of the detent, the arm 29 is shifted rearwardly as is more particularly shown in Fig. 5, by the action of the spring 30 which is stretched between a fixed point on the machine and a pin 3!) on said lever 29. Rearward movement of the arm 29 tilts the tiltable frame l8 to elevate the pressure roller I6 and stop further feeding of the yarn. This movement is accomplished through the connecting rod 3 I, pivoted at one end 3| to the said arm 29 and at its opposite end 3| to the top of the tiltable frame [8 which comprises a lever arm 32 fastened at 32' to the tiltable bearing frame l8 in which the roller I6 is mounted. The lever 32 is normally held in its forward position to retain the pressure roller H5 in proper pressing relationship by the spring 32 Thus, upon a revolution of measuring mechanism connected with the roller Hi, the rearward movement of the sliding arm 29 will elevate said roller IE to cause further feeding of the yarn to be immediately discontinued. Obviously, by properly proportioning the gears and pressure-applying roller any suitable yardage fed therethrough may be measured and the feeding then stopped.

Upon such discontinuation of the feeding movement of the yarn, the operator, in the embodiment illustrated, cuts the yarn between the funnel and the head of the capsule 5; then removes the capsule from its socket and replaces another one in said socket. During such removal of the capsule, it is desir able that the suction be shut-off and for this purpose I provide means for cutting off the suction simultaneously with the discontinuance of the feeding movement. As illustrated, one end 33 of the connecting rod 33 is connected to the sliding lever 29 and the other end thereof is connected to a cut-off valve 34 which is normally open and is closed against the action of the spring 34' by movement of the arm 29 in a rearward direction upon release of the detent 28. As illustrated, the valve is mounted on an extension arm 35 connected to the bracket 3 and embodies a casing 34 having a slidable valve member 34 provided with a valve opening 34 normally held in registry with the inlet and outlet portions 34, 34 which are connected intermediate the ends of the hose 1 connected to a pump P. When the valve 34 is operated to shut off connection between the pump P and capsule, another channel is preferably provided to permit the pump to continue its normal operation during suchmut-off period, and for this purpose I provide a conduit member p having suitable means (not shown) adapted to open automatically upon the closure of the valve 34.

After a new capsule is inserted in the socket 4, the end of the thread is inserted through the aperture in the head of the capsule and then the lever 29 is moved forwardly by the operator to cause the detent 28 to look within its notch 29' whereupon the feed of the yarn will again be started. As illustrated, a hand lever 36, pivoted on the frame at 36', is connected intermediate its ends at 36 to the lever 29 and is provided, at its end, with a handle 36* which may be grasped by the operator to swing thelever forwardly in order to connect the detent and cause the start of the feeding movement of the yarn as above indicated.

I have found that it is not necessary to discontinue the hammering movement of the socket and capsule during removal and renewal of the capsule. As shown, the shaft 1 0 for the hammering cam is rotated through the sprocket l0, chain belt Ill and sprocket lo from the shaft l5 which is extended beyond its bearing for this purpose.

Suitable guides for the yarn are provided and, as shown, I have employed an eye-guide 31 and a V-guide 38 at the rear of the pressure roller. Of course, conventional means (not shown) is provided to stop the machine entirely when desired.
