In the drawings, wherein for thepurpose of illustration, it have shown a preferred embodiment of the invention, the letter A denotes a creel for holding the general supply of yarns, 25 B the selector machine and C the warp beam. winding, machine. The frame of the selector machine consists of vertical standards 6 and l connected at their upper and lower ends by cross beams ii and 9. Extending longitudinally of the 30 frame are a series ot horizontal tracks iii arranged in vertical spaced superimposed relation, each track consisting of a pair of spaced parallel rods ii connected at their ends to the standards of the frame by nuts l2. A series of individual yarn carriers I3 are slidably mounted onthe tracks l0, each carrier consisting of an elongated block having transverse openings i4 therethrough. for the passage of the rods ii on which the carriers slide. A tubular sleeve I, through which 40 the yarn it extends, is secured tothe upper edge of the block and extends the length thereof. Each horizontal row of carriers support yarns or the same color while the vertical rows are made up of yarns of diii'erent colors. The number of yarns in each horizontal row will vary according to the pattern'oi the carpet or rug for which the yarns are to be selected. The general supply of yarns for theearriers is provided from the creel A. The creel is preferably of a type which will permit free unwinding of the fyams from the cheeses, with friction driving means for rotating the cheeses in a reverse direction to take up the slack in the yarns when desired.

The carriers II are moved along the tracks ll v intersect the openings i4 and by reason of their by rotatable shafts l'l extending from the vertical plate is which is provided with openings I! for the passage of the rodsi I therethrough, to permit sliding'movement of the plate along the tracks. The upper and lower ends of the plate II have screw threaded blocks l5 and 20 to receive the screw shafts II and 22 at the top and bottom of the selector frame. The shafts 2| and 22 have one end mounted in bearings in the standard I while their opposite ends are journaled in bearings 23 and 24 attached to the upper and lower cross beams of the frame. The rotatable shafts I! extend longitudinally of the tracks I! intermediate the rods H and each of the carriers if is provided with a central opening 25 through which the shaft I1 is adapted to extend. The carriers are retained on the free end of the shafts I! by a pin 26 extending transversely through the shafts, the opening 25 being provided with opposed notches 21 to permit separation of the individual carriers from the shafts il when the shafts are rotated to bring the pin 26 in register with the notches. The carriers on one side are provided with recesses 28 surrounding the openings 25 which permit free oscillation of the shafts i1 and pins 28 after release of the individual carriers. A stop block 29 slidably mounted on the track and shaft holds the series of carriers close' together and an adjustable sleeve 30 mounted on the shaft holds the block in position. The inner end of the shafts II project through and extend slightly beyond the plate ll having pinions 3i fixedly mounted thereon which mesh with the rack bars 32 extending transversely of the plate Hi. The rack bars at one end are supported by guide brackets 33 and at their opposite ends are connected through links 88 to the core 35 of a solenoid magnet 36. When the magnets are energized the rack bars are moved to turn the shafts I! a quarter of a turn to aline the pins 25 at the end of the shafts with the notches 21 of the openings 25 through the carriers, thereby permitting the end carrier on the shaft to be detached therefrom. Upon release of the end carrier from the shafts i1 its movement is arrested by means of the spring wire 31 extending longitudinally of the bottom edge of the carrier and attached thereto intermediate its length.-'1he ends of the wire 31 are freely movable in the vertical slots 38 in the ends of the carriers, which resiliency frictionally engage the rods ll holding the carrier at the point on the track where released. When the solenoid magnets are de-energized the rack bars 32 are moved in the opposite direction by the coil springs 35 attached at one end to a pin 40 carried by the rack bars and at .thelr opposite end to a pin ll carried by the guide plate 42 disposed above the rack bars. The free ends of the rack bars 32 project slightly beyond the edge of the plate II and are adapted to be engaged by the bar ll supported by brackets 44 attached to the plate ll. The bar 43 is mounted for movement in a direction towards and away from the ends of the rack bars, being operated by a manually actuatedlever 44' which actuates a rod 45 having arms 45 in engagement with the bar 43 which move the bar towards the ends of the rack bars, to simultaneously move all the rack bars in a direction to rotate the shafts II, so that the pins 25 aline with the notches 21, permitting the shafts to freely pass through the openings 25 of the carriers -released upon the tracks, when the machine is being returned to a starting position. The lever 44' is normally held in an inoperative position by the spring 41.

An automatic circuit closing and opening mechanism is provided for controlling the energizing of the magnets 36 and includes a stand 48 having mounted thereon an insulation contact block 40 supported by arms 50 pivotally mounted on the frame members 5i by pivot pins 52. Contact strips 53 of suitable conducting metal are positioned on top of the block 49 in parallel spaced relation, there being one contact strip for each of the magnets and one for the magnetic clutch II. An adjusting screw 55 engages the rear ends of the arms 50 for regulating the pivotal movement of the contact block and beneath the forward end of the block, at each corner, are coil springs 56 which cushion the downward movement of the block and returns the same to its-normal position. A roller 51 is mounted forward of the contact block having a series of spaced longitudinal grooves 58 in its periphery and at each end sprocket teeth 59. A pattern sheet II! is trained over the'roller having perforations along its edge which engage the sprocket teeth 59, whereby the pattern sheet is caused to move over the roller upon rotation thereof. The pattern sheet is fed to the machine from a spool I mounted at the forward end of the stand and is rewound on a driven spool 62 at the rear end of the stand. The pattern sheet has openings 53 punched therethrough which aline with the grooves 50 as the pattern moves over the roller 51. A series of trip levers 54 are supported above the roller 51 in a guide comb 65 and mounted in the outer ends of the levers H are pins 68 which move over the surface of the pattern. A spring 51 normally urges the pins 86 in a downward direction so that when the openings 63 aline with the pins, the pins are forced downwardly into engagement with the groove of the roller, whereby the trip lever M is caused to move in the direction of rotation of the roller. The inner ends 68 of the trip levers 54 are circular shape and fit in correspondingly shaped sockets 69 of the hanger plates II which are disposed vertically in a guide frame I I the upper ends being bifurcated, as at 12. to engage a guide rod 13 while the lower end bears against the lower member of the frame II The individual hanger plates III are normally held in a raised inoperative position by springs I4 mounted on the bar I! which engage the lip 15 formed on the edge of the hanger plates. A rocker am 11 is mounted on a rocker shaft 18 above the contact block and at its forward end carries a plate 19 adjustable by means of a screw II. A shoulder II is formed on the rear edge of the hanger plates I5 and when the hanger is moved inwardly through the action of the trip lever, the shoulder is disposed in the path of movement of the rocker arm plate I! which strikes the shoulder and causes the hanger plate to move downwardly, so that the lip I! engages with the contact strip 53 to close the electric circuit of one of the magnets. The wires 82 leading from the contact strips 58 have plugs 03 at their ends for detachable engagement with the sockets I in a switch panel 85 and wires 85 leading to the magnets from the sockets are housed within a flexible conduit 81. The plugs Cl permit ready interchanging between the circuits of the individual magnets, so that a change or alteration may be made in the pattern being selected without the necessity of punching a new pattern sheet. To facilitate changing of the circuits, numbers are applied to the plugs l3 and III the ends of the stop blocks 20 of each horizontal row of carriers. I

A warp clamping member forholding the loose ends ofthe yarns during the selecting operation is positioned forward of the selector frame being mounted to move in a direction longitudinally thereof. All the yarns extending from the carrlers are held by the warp clamp at the beginning of the selection operation and after the carriers have been selected for a particular line, the yarns of the selected carriers are removed from the warp clamp and clamped in the winder beam C. The unselected yarns are retained in the clamp member and thereby held separate from the selected yarns. The clamp consists of a vertical angle bar 88 having screw blocks 89 at its upper and lower ends which travel on the screw shafts 90 extending longitudinally of the selector frame. The screw shafts are journaled in bearings 9| mounted on the vertical posts 92, positioned in a line at a slight angle to the selector frame so that as the clamp moves across the frame it is brought nearer tothe frame. A sprocket wheel 03 is mounted. on one end of each shaft and an endless chain ill connects the sprocket wheels of the shafts so that they turn in unison. Attached to one edge of the angle bar 88 is a comb 95 through which the yarns are inserted and to one side of the comb is a rotary wire brush member 06 for receiving and. holding the ends of the yarns drawn through the comb. The ends of the member are fastened to the bar 88 by bolts 91'.

The mechanism for collecting the yarns which have been selected by the selector machine consists of a fan shaped comb 98 composed of a series of flat metal teeth 90, disposed in spaced parallel relation and connected at one end to a bar I00. The teeth of the comb at their outer free ends are spaced farther apart than at their inner ends, the intermediate portion of the teeth being bent at an angle to direct the yarns entering the teeth at their outer ends towards the inner ends of the teeth, thus drawing the yarns into closer relation. The comb 08 is supported in a horizontal plane by a rectangular frame IM suspended on a horizontal plane in front, oi the selectbrmachine by vertical rack bars I02 extending through the uppercross beam 8 and mounted in suitable guideways attached to the frame of the selector.

The rack bars I02 mesh with gears on the shaft I03 mounted on top of the beam l'which is driven by a-reversible electric motor I04. The bar I00 rests loosely on the rear longitudinal member I04 of the frame IIlI, whilethe forward ends of the teeth of the comb are disposed in guide slots I00 formed in the top of'the front longitudinal member'lfll' of the frame IOI. The teethare held in the slots by a bar I08 removably held on top of the teeth by pins I01 projecting upwardly from the frame IOI, which engage in openings in the ends of the bar. The forward ends of the teeth W project beyond the frame "I and as the comb moves downwardly past the front of the selected carriers the yarns are collected between the teeth.

Upon reaching the bottom, the bar i0 is re-.'

moved and the bar III is swung upwardly towards the. selector machine to dispose the comb in a vertical plane. The frame III is then returned to its original position at the top of the selector frame and then the comb is drawn along the selectedyarns towards the warp beam winding machine C; during which operation the yarns move towards the inner ends of the comb teeth, into closer spaced relation for attachment to the warp beam of the winding machine. The comb containing the selected yarns is supported on the front'of the warp beam winder by suitable brackets andguides the yarns during the winding operon the end of the screw shaft 22 projecting beyond the standard 6. A sprocket wheel I I3 is also fixed on the screw shaft 22 and is connected with the sprocket wheel I I4 fixed on the screw shaft 2| by an endless chain 5, whereby the screw shafts are rotated in unison to move the plate I8 longitudinally of the selector frame. A gear wheel I I6 mounted on shaft 2|, through an intermediate gear II1, drives the gear 8 fixed on the horizontal shaft H9 mounted in a bearing I20 attached to the standard 0. The shaft II9 carries a bevel gear I2I which meshes with the bevel gear I22 at the upper end of the vertical shaft I23 mounted in bearings I24 attached to the standard 6. A bevel gear I25 is attached to the lower end of the vertical shaft I23 and meshes with a bevel gear I26 on the end of the drive shaft I21 which through a worm I20 drives the worm gear I29 on the end of the shaft of the roller 51, whereby the roller isrotated to feed the'pattem sheet 60. A pulley I30 on the drive shaft I21 is connected by an endless belt I3I with the pulley I32 on the shaft of the spool 62 for rewinding the pattern sheet on the spool. A rocker arm I33 connected to the end of the rocker shaft 18 is actuated by a cam I34 mounted on the shaft I21. The magnetic clutch B4 is interposed in the shaft I21 for automatically controlling the drive shaft, the electric circuit of the magnetic clutch being controiled by one of the contact strips 03 of the automatic circult closing and opening machine. The gear wheel I it also meshes with an intermediate gear I26 which drives the gear I21 mounted on shaft M0. The shaft I30 is connected by a universal joint I39 to the shaft Ill, which through the universal joint lltcon'nects with the upper screw shaft of the warp clamping member. A magnetic brake I42 is mounted on the free end of the motor shaft Ill which connects with the circuits of the motor I00 and is brought into operation upon bre M g of the circuits to stop the motor. Various manual and automatic switches are interposed in the circuits for stopping and startingthe motors I00 and I 0|.

In operation, the yarns II are supplied from the creel A, the individual yarns being drawn through the tubular sleeves II of the individual yarn carriers I2 mounted on the horizontal tracks II of the selector machine. The carriers of each track will carry yarns of the same color and the number of tracks employed in the selection of the yarns will depend on the number of colors in the pattern of the carpet or rug for which the yarns are to be selected.

After. the carriers are supplied with the desired colored yarns, the loose ends of the yarns projecting from the carriers are secured in the cuit opening and, closing machine and also imparts movement to the'rocker shaft 10. As the 75 18 to bring the shoulder ll of the hanger plate into the path of movement of the rocker arm plate 19 which is constantly reciprocated by the rocker shaft I8. The rocker arm plate 18 upon engaging the shoulder ll forces the hanger plate downwardly so that-the lip ll engages the contact strip 53 to close the circuit of the magnets 8| which are supported by and move with the platell. Upon energizing the magnets ii, the rack bars 32 are moved torotate the shafts II which extend through the openings 25 of the yarn car.- riers, so that the pins 28 are alined with the notches 21 of the openings, therebyreleasing the outermost carriers on the shafts. The carriers when released are held in position on the tracks by the spring wires 81 which frictionally engage the rods of the tracks. The circuits of the magnets are only momentarily closed and upon deenergizing of the magnets, the rack bars are moved by the springs 38 to rotate the shafts H in a reverse direction so that the pins 28 are moved out of alinement with the notches 21 looking the remaining carriers on the shafts. Thus, it is seen the pattern sheet 60 automatically controls the opening and closing of the magnet circuits and the magnets control the release of the carriers from the shafts H, as the carriers are moved along the tracks. 1

During the selecting operation, the warp clamping member holding the loose ends of the yarns is moved longitudinally of the selector frame in unison with the carrier moving means and when the selecting operation for theparticular line is completed, the selected yarns are removed from the clampingmember and the unselected yarns are retained by the clamp in separate relation to the selected yams.

On completion of the selectionof the desired yarns the motor is stopped and the selected yarns are permitted to .hang downwardly in vertical relation to the selector frame. The motor I04 which drives the yarn collecting mechanism is then started and the collector comb 98 is lowered past the front endsof the selected yarn carriers, so that the yarns hanging therefrom are collected between the forward ends of the comb teeth. When the comb reaches the bottom it is manually lifted off the frame Ill and swung to a vertical plane, at which time the motor I is reversed to return the frame Iii to its uppermost position.

The comb'98 is then drawn along the yarns so that the yarns are caused to move towards the inner ends of the comb teeth which are spaced closer together, thereby drawing the yarns closer together and in proper relation for attachment to the warp beam of the winding machine C. After winding the selected yarns on the warp beam. the operation of selecting the yarns is completed and the motor lllis started in reverse to drive the shafts II and 22 to return the plate I! to its starting position.. At this time, the bar 43, through operation of the lever 44', is actuated to move all the rack bars 3! in a direction to rotate the shafts II to bring the plus it in alinement with the notches 21 of the openings 25 of the carriers, so that as the platfii returns to its starting position, the shafts Il pass through the openings of the yarn carriers distributed along the tracks, automatically collecting the carriers for the next operation of the machine.
