14 Claims.

This invention relates to a method and means for applying metallic shields to spool heads so that the periphery of the head will have a smooth surface which is contacted by the 'yarn as it is drawn from the spool. Spools are usually made from a suitable wood, which is usually a hardwood; consequently the flanges become .worn or splintered after slight use,.thus creating irregularities which are engaged by the yarn as it is drawn from the spool. Some spool heads have been made of sheet metal but these are expensive and easily bent out of shape. Other spool heads have been made from a wear-resisting composition material but these are expensive and have certain undesirable features. By affixing a metallic rim around the periphery of a wooden head, proper strength is obtained, low-cost production is made possible and the yarn on the spool does not engage the wood, but instead acts as a shield and wearing surface.

It is also necessary to reinforce these'heads with a suitable band to make them substantial enough to withstand the ordinary wear and tear in the mill when the spools are not inuse on a textile machine. If a combination of metal and wood is used to form a spool head, the thickness of the head can be substantially decreased without afiecting the strength and durability of the spool.

The general purpose of the inventionis theprovision of an improved apparatus for producing spools of the type specified, comprising means for holding a plurality of preformed shields in a magazine, means actuated by the insertion of a spool for releasing one of said shields to allow it to be positioned adjacent a spool head, means for moving the spool endwise and clamping it against the released shield, means for rotating both the spool and the flange, and means for crimping said shield into the flange during this rotation of the spool.

It is a further object of this invention to provide a method of affixing a shield to a spool'head which shield is preformed so as to engage the periphery and adjacent portions of the outer sides of the head, the steps of which comprise the positioning of the spool for the reception of the head, the moving of the spool head end'wise and clamping the shield thereon, then rotating both the head and the shield while one edge of said shield is spun against the inner face of the head and the other edge portion of the shield is spun into a circular cavity in the outer face of the head.

Some of the objects of the invention having been stated, other objects will appear as the description proceeds when taken in connection with the accompanying drawings, in which- Figure 1 is a top plan view of my improved apparatus for placing shields upon spool heads with the feeding apparatus omitted;

Figure 7 is a sectional plan view taken along the line 1-1 in Figure 6;

Figure 8 is an elevation looking at the righthahd end of Figures 1 or 2;

Figure 9 is an enlarged sectional view similar to the central portion of Figure 1 but showing a spool with its head and shield in a position where theshield is being spun onto the head;

Figure 10 is an enlarged vertical sectional view similar to the central part of Figure 2, showing the position of the spool head and the shield iminediately before the spinning action is 'efiec'ted.

Shield feeding mechanism Referring more specifically to the drawings, the numerals Ill and H denote suitable end supports which have mounted thereon a bed plate [2;

. Secured around the central ,portion' of the 'bed plate I2 is a framework M which is adapted to support the feeding mechanism which allows suitable shields I?) to fall in position for being secured to'the ends of the spool heads. By referring to Figures 2 and 6, it is seen that the shields l 5 are circular and are stacked one upon the other between guide'ways I'I. These guideways have grooves It in their proximate faces so as to accommodate the shields l5.

In order to adjustably secure these guidememhers I"! to the framework l4, suitable slots l9 are provided in the framework and these slots are adapted to be penetrated by bolts or screws 20 which also penetrate the vertical guide members I7. By loosening the nuts on the bolts or screws 20, the distance between the proximate faces of the guide members can be varied to accommodate shields of difierent diameters.

The stack of shields I5 is normally supported by the end of a horizontally disposed bolt 22 (Figures 6 and 7). This bolt is adjustably secured in an arm 23 which, in turn, is secured to the rod 24 directly above the arm 23, and adjustably secured in the free end of this arm is a bolt 26, which bolt is positioned substantially midway between the two lowermost shields. In Figure '7, it is seen that the bolt 22 projects beneath the lowermost shield I5; whereas the bolt 26, thereabove, is in such a position that the shields may move downwardly without contacting its end. When it is desired to release the lowermost shield between the guides I1, it is necessary to slightlyrotate the shaft 24 in a clockwise manner in Figure 7, thereby causing the end of bolt 22 to move out from beneath the lowermost shield l5 and at the same time causing the end of bolt 26 to move be neath the adjacent shield thereabove to prevent it from falling.

The vertically disposed rod 24 is mounted for oscillation in bearings 28 each of said bearings having a slot 29 therein which is penetrated by a stud bolt 30 which has its end threadably secured in framework I4. By manipulating the bolts 30 and the bearings 28, the position that the supporting bolts 22 and 26 occupy relative to the center line of the shields I5 can be varied.

In order to limit the oscillation of shaft 24, a suitable stop bracket 34 has been fixedly secured around the upper end of the rod-24, said bracket having prongs 35 and 36 integral therewith (Figures '5 and 6). The prong 35 is penetrated by bolt 31, the end of which is adapted to rest against the face of framework I4 when the rod 24 has been oscillated its limit in a clockwise direction in Figure '7. In order to provide a stop when the shaft 24 oscillates in a counterclockwise manner in Figure '7, a bolt 38 has been provided in the prong 36. v

The lower portion of rod 24 (Figure 6) has fixedly secured thereto a lever 40, the outer end of which has a ball 4| extending upwardly therefrom and this ball fits into one end of a link 42. The other end of the link 42 is adapted to fit over a ball 43 (Figure 5) in the upper end of a bell crank 44, said bell crank being fixedly secured around a transversely disposed shaft 45'. The

outstanding leg of bell crank 44 has a weight 46 adjustably mounted thereon so as to provide the necessary weight to normally hold the end of supporting bolt 22 beneath the lowermost shield I5 in the manner shown in Figure 7. Of course when the end of the bolt 22 is beneath the lowermost shield as just stated, the end of the stop bolt 38 in'Figure 5 will be contacting the frame work I4 in the manner shown.

' The shaft 45 is rotatably mounted in bearings 48 and 49 on the top of bed plate I2. Fixedly secured to the intermediate portion of the shaft45 (see Figure 2) is an L-shaped lever 50, the horizontal leg of which has a bolt 5I therein penetrating a slot 52 in an upwardly extending treadle 53. The top of treadle 53 is positioned at a slightly lower level than a V-shaped spool support 54 (see Figures 1 and 2). This V-shaped support is adapted to accommodate the barrel 55 of a spool 56 in the manner shown in Figure 9, said barrel having suitable flanges or. heads 51 and 51a on its ends. When the spool is placed in the V-shaped support 54 in the manner shown in Figure 9the lowermost portion of the spool head 51 will normally rest upon the treadle 53.

The pressure exerted by the lower portion of the spool head 51 upon the treadle will cause its associated lever 50 to rotate in a counter-clockwise manner in Figure 2 thus causing the bell crank 44 (Figure 5) to rotate in a like manner so that the link 42 will move to the left. This movement to the left in Figure 5 of link 42 will cause the lever 40 in Figure 7 to rotate shaft 24 in a clockwise manner and thus cause the lowermost supporting bolt 22 to move out from beneath the lowermost shield I5 and at the same time cause the supporting bolt26 thereabove to move beneath a shield and support it in this position. When the spool is removed from the V-shaped support 54, the weight 46 on the end of bell crank 44 in Figures 5 and 7 will return the supporting I bolt 22 to the position shown in Figure 7 and also rotate the next uppermost bolt 26 to the position shown. This, of course, will allow the shield which was previously supported by the uppermost bolt 26 to fall downwardly between the guides and upon the end of lower supporting bolt 22. It is therefore seen that each time a spool is inserted in the proper position that a shield is released from the magazine thereabove.

Supporting mechanism for released shields Secured to the face of the framework I4 (Figure 6) directly above the bed plate I2, is a plate 58 "by' any suitable means such as bolts 530.. Adjustably secured by bolts 60 to the face of this plate is'a pair of angularly disposed brackets 59 and each of these bolts is adapted to penetrate a slot 6I in this bracket. The'upper end of each bracket has a plunger 62 mounted therein. It will be noted by observing Figure 6 that each of these plungers are radially disposed about the longitudinal center line of a shaft II9. Also it is. to be noted that the center line of the shaft H9 is in alinement with the longitudinal center line of the spool 56 when itis placed on support 54. and in the position for placing a shield I5 thereon. The plungers 62 are normally held in an extended position as shown in Figure 6 by meansof suitable compression springs 68. The

purpose of providing these plungers and brackets is .to' support the lowermost released shield I5 in the'proper-position so that when the spool head 51 is moved longitudinally of the center line of the barrel 55, the shield will be in such a'position as to fit over this spool head. It is of course evident that'if the diameter of the spool head 56 changes ,a corresponding change must be made in the-shield and also a corresponding adjustment must be made. in the positions of the brackets 59. In other words, the center line of the released shield must be concentric with the longitudinal center line of the barrel 55, before the spool head 51 is moved into the released shield.

Clamping mechanism for spool and released shield After the spool. 56, has been placed in the support 54 and a shield has been released, the parts are in the position shown in Figure 10. It is then necessaryto move the spool endwise, thatis to the leiftfrom the position shown in Figure 10 ;to the position shown in Figure 9 to cause the shield to be inserted over the periphery of head has a washer 73 mounted therearound which will engage theouter face of head 51a, if the hole .10 is large enough to permit the plunger to penetrate it this far. Upon the penetration of the plunger the spool head is moved endwise toward the'released shield.

The right hand end of'the shaft I2 has a collar '14 integral therewith (see Figure 2) and disposed on opposed sides of this collar are thrust bearings I and 16. The bearing 16 has one end of a compression (spring 11 normally pressing thereagainst which will cause the lefthand end of shaft I2 to be pushed out to extended position. The right hand end of the spring 11 is normally resting against a washer I8, which washer is slidably mounted in bore I9 inside of a casing 80. The Washer I8 has one end of a screw BI rotatably mounted thereon, said screw having its intermediate portion threadably mounted in cap 82 which, in turn, is threadably secured in the right hand end of casing 80. By adjusting the screw 8! it is seen that the amount of tension placed upon the spring 11 can be varied, which will likewise vary the resistance offered by the left-hand end of shaft I2 to the end of the spool.

Plunger 'II has a collar Ha integral with its intermediate portion which fits into a bore 83, said bore having a compression spring 84 mounted therein. This spring normally presses the plunger]! outwardly until the collar I la engages washer 73. This construction provides a resilient mounting for the plunger.

The casing 89 is adjustably secured in bracket 85 by any suitable means such as set screw 86. This bracket has its lower portion secured to dove-tailed slide 81 by any suitable means such as bolts 88, the heads of said bolts being adapted to fit into longitudinal groove 89 in the top of dove-tailed slide (see Figures 2 and 8). Extending from the lower side of the slide 81 is a lug 87a to which is pivoted as at 90, a link 9|. The link 9I is pivoted as at 92 to the vertical leg of bell crank 93, said bell crank being pivoted as at 94 to bracket 95. This bracket 95 is secured to a cross channel support 95 by any suitable means such as a bolt 91. The horizontal leg of the bell crank 93 has a roller 98 thereon and this roller normally rests upon cam 99 on the end of cam shaft I00. normally upon the periphery of cam 99, a suitable tension spring IIlI is provided. If it is desired to adjust the tension on the spring IOI, a suitable bolt I02 is manipulated.

As the slide 81 moves to the left in Figure 2, the spool support 54 also moves along with it. This support is adjustably secured to bracket I04 by means of bolt I03, said bolt penetrating slot I03a in the support; therefore the elevation of the support 54 can be varied. Bracket I04 is secured to slide 8'! by means of bolt I04a and this bolt has its head mounted in slot 89 in the slide. If it is desired to move the support 54 longitudinally of the machine, it is only necessary to reposition bolt 34a in slot 81.

As the shaft I09 is rotated the bell crank 93 is caused to oscillate back and forth which in turn will cause the slide 81 and its associated shaft 12 to reciprocate back and forth. For example, when the roller 98 rides on the high side of cam 99 (Figure 8) the plunger II will move to the left in Figures 1, 2 and 9 to cause the right-hand end of bore III to be penetrated. This movement will In order to hold the roller 98 also c'ausethe left hand head 51 of the spool to move into released-shield I5, which in turn will move into'a hole I05 in the manner shown in Figure 9. Due to the fact that hole I05 is the same diameter as the shield I5, it is seen that the shield as well as the head 51 will move into this cavity thereby providing a chuck or clamping member for engaging the left hand end of the spool while the righthand end is engaged by the plunger II. I

By observing Figures 2 and 6, it can be seen that the hole I05 is disposed in plate I06, said plate being secured to bell shaped member I01 by any suitable means such as screws I08. This plate is made removable due to the fact that it,

very often is necessary to provide a'larger or smaller hole I05 in the plate for gripping spool heads of different diameters. In any event the cavity or hole I05 acts as a chuck for holding one spool head in position whereas the plunger II fits into the bore I0 to hold the other end of the spool. It is in this clamped position that the metal forming takes place to cause the shield to be spun securely around the periphery of the spool head 5].

The bell shaped member I0? is threadably secured upon the right hand end (Figure 2) of a sleeve IIO, said sleeve being journaled in bearings II I and, H2 and these bearings form an integral part of slide H3. The slide H3 is secured upon the top of bed plate I2 and between guide plates H4 and H5 (Figure 1). These plates are secured to the top of the bed plate by means of bolts I I6 and i ll, respectively. When the slide II3 has been placed in an adjusted position, the bolts I I5 and II I are tightened to prevent any further movement.

Mechanism for spinning the shield onto the exterior face of the spool head Mounted for longitudinal sliding movement within the'sleeve H0 is a shaft II9, said shaft having threadably secured on its right hand end (Figure 2), a suitable bar I20. Secured to the bar I20 by any suitable means such as bolts I23 and I24, respectively, are brackets I 2| and I22. The bolts I23 and I24 penetrate suitable slots I25 in the bar I20 thereby making it possible to vary the distance that the brackets I2I and I22 occupy from the center line of shaft II9. Each of the brackets HI and I22 has a roller I26 mounted therein. These rollers are adjusted so as to lie on the same radius with respect to the shaft II9. Also these rollers are placed in such a position relative to the center line of the bore I0 in the spool barrel 55 that their periphery will engage an annular groove I3I} in the vertical flange of shield I5. This groove I30 in the vertical flange is adapted to fit in an annular groove I3I in the exterior face of spool head 5'! as shown in Figure 10. The purpose of providing the rollers is to have them firmly press that portion defined bythe groove I30 of the shield into the groove I 3| in the spool head.

The rollers I25 are moved to the right from the position shown in Figures 2 and 10, to the position shown in Figure 9, immediately after the opposed ends of the spool 56 are engaged by plate member I06 and plunger In order to have means for moving these rollers to the right at the proper time, a suitable connection has been provided between the shaft II 9 and the camshaft I00. This connection comprises a fitting I35 which is fixedly secured around the left hand end of shaft H9 and the lower end of this fitting has a bolt I36 extending therethrough which penetrates a slot I31 in the upper end of lever I38, said lever I38 being'pivoted as at I39 to bearing I40. The bearing I40 is secured to the end support I I. This bearing is also adapted to accommodate the lower end of a cam shaft I4I which shaft is also mounted for rotation in a bearing I42 thereabove. Secured to the upper end of shaft MI is a cam I43, said cam being normally engaged by a roller I44 which, in turn, is secured to the intermediate portion of lever I38. This roller is normally held in contact with the cam I43 by a tension spring I45. Cam I43 is shown in Figures 2 and 4 with the high side engaging the roller I44; consequently the metal spinning rollers I26 on the righthand end of the shaft II9 are withdrawn from the hole I05 in plate I06 and from the end of the spool head. As the shaft I4I rotates, however, to a position where the low side of the cam will be contacted by roller I44, the spring I45 will normally move the shaft II9 to the right to thereby force the rollers I26 through the opening I05 to the position shown in Figure 9 at which time the rollers will engage the preformed groove I 30 in the vertical face of shield I5.

The lower end of the shaft I4I (Figure 2) is driven by the main drive shaft I00 through the medium of beveled gears I41 and I48, the gear I41 being disposed on the lower end of shaft MI and the gear I48 being disposed on the left-hand end of cam shaft I00.

Driving mechanism for cam shaft 100 The cam shaft I00 has its ends mounted in bearings M9 and I50 which bearings are secured to the end supports I0 and I I, respectively. This shaft has a gear I5I fixedly secured thereon which meshes with a pinion I52 on shaft I53, said shaft I53 having its ends journaled in bearings I54 and I55 extending outwardly fronrsupports I0 and II, respectively. The right hand end of shaft I53 (Figure 1) has a relatively large gear I56 fixedly secured thereon and this gear meshes with a small pinion I51 on the right-hand end of shaft I58 said shaft I58 being rotatably mounted in bearings I59 and I60 on framework I6I, said framework being supported between members I0 and II. The left-hand end of the shaft I58 has a pulley I62 thereon upon which is mounted a belt I63. This belt is also mounted Figure 9.

Mechanism for spinning the shield against the inner surface of the spool head Simultaneously with the movementto the right of the roller I26 to engage the vertical face of the shield I5 in the manner shown in Figure 9, a second pair of rollers I66 move to the left in Figures 1, 2 and 9 to spin the projecting rim of the horizontal flange of the shield I5 against the inner face of head 51 and into groove 64. The forming rollers I66 are mounted on the upper end of arms I61 and these arms extend downwardly and have their lower ends adjustably secured as at I68 to transversely disposed shafts I69. It is seen by observing Figure 1 that the two shafts I69 are separate andtherefore,

independently operable, the proximate ends of these shafts being coupled together by means of a' collar I10. This collar however does not prevent relative rotation from taking place between the shafts. Also since the arms I61 are adjustably mounted by means of set screws I68, their position on their respective shafts I69 may be varied to accommodate spool heads of different diameters.

Fixedly secured on the outer ends of shafts I69 arebell cranks 'I1I, the upstanding leg of each bell crank having a bolt I12 extending therethrough which also penetrates a slot I13 in a horizontally disposed link I14. The right hand end of each of these links is pivoted as at I15 to a shaft I16, said shaft I16 having a collar I11 adjustably secured thereto by any suitable means such as set screws I18, the intermediate portion of each shaft I16 being slidably mounted in a bearing I19 which, in turn, is supported by a block I (see Figure 8). The dove-tailed slide IBI also supports the dove-tailed slide 81, previously described. Slide IBI is mounted for sliding movement between guide plates I82 and I83 on the top of bed plate I2.

By observing Figure 1, it will be noted that each shaft I16 has a spring I85 mounted therearound with one end of the spring abutting the bearing 119 and the other end abutting a suitable collar l66, said collar being adjustably secured around the shaft by any suitable means such as set screw 501. The purpose of providing the springs I85 is to have the desired amount of flexibility when the rollers I66 are moved to the left into contacting-position with the lateral flange of shield I5. In other words, should there be a difference in the width of the head 51 then one roller could move farther inwardly toward the hole I05 than the other without transmitting undue pressure upon the thick side of the flange. This spinning orforming action by the rollers I66 as heretofore stated, takes place simultaneously with the inward movement of rollers I26. Consequently, the pressure is being applied simultaneously to opposed sides of the spool head 51 so that the head will'not be placed under any undue strain. When it is necessary to move the rollers inwardly, from the position shown in Figures 1 and 2 to the position shown in Figure 9 the slide I8I is moved to the left in Figures 1 and 2. This slide has a downwardly depending lug I integral with the left-hand end thereof and pivoted to this lug as at I8I is the right hand end of a link I92. The left hand end of link I92 is pivoted as at I93 to the upper end of bell crank I94, said bell crank being pivoted as at I95 to bearing I96. The bearing I96 is secured to a transverse channel member I91 by means of bolt I98. Rotatably mounted upon the end of the horizontally disposed leg of bell crank I95 is a roller I99. This roller normally contacts cam 200 on drive shaft I00. The cam 200 is similar in many respects to the cam 99 on this same shaft except for the fact that the dwell is somewhat shorter. In other words, the cam 200 is so shaped that the rollers I66 will not be moved into engaging position until after the cam 09 has moved the shaft 12' to the left to clamp the spool and shield in position.

Spool rotating mechanism Thus far in the description means have been described for first releasing a shield to inserting position, means for clamping a spool head against the released'shield, means for moving suitable forming rollers into contact with the .outer'face of the shield and means for movinga second pair of forming rollers into contact with :the: inner rim of the shield to perform a second spinhing operation. The final operation. comprises the rotating oi" the shield and the spool to allow the stationary rollers [26 and, lfit to. perform their: spinning operations as theshield with itsspoolturns The hollow shaft Hill has: a pulley 205: secured; thereon by any suitable meanssuch as-set screw 206 (see Figure. 2) This. pulley is driven from a separate source of power not .shown but it evident that, when thispulley .isrotated, the. hollow shaft will be rotatedas well; as bell; shaped member in! and the plate l06=,.iwhich-pIate thrust. bearings. are mounted. in the manner. shown it is possibleiior the shaft 1'2 to rotate along with the spool. 56. during the crimping operation.
