SPOOLER.

Application filed February 21, 1921. Serial No. 446,572'

T 0 all whom it may concern Be it lmown that T, ALoNzo E. Rrronnns, a citizen of the United States and resident of Hopedale, county of lVorcester, State oi? Massachusetts, have invented an Improve ment in Spoolers, of which the following description, in connection with the accompanying drawing, is a specification, like characters on the drawing represent-ing like parts This invention relates to improvements in spoolers and the object thereof is to pro vide a novel and positive mechanism for reciprocating the traverse rod relatively to the spool carriers of the spooler. Where different sizes or counts of thread or yarn are to be spooled, spools of different lengths are employed. In order to wind the coarser thread or yarn properly upon larger spools the speed of traverse and also the amplitude of traverse must be increased and vice versawhen finer yarns and smaller spools are employed the speed and length of traverse must be correspondingly decreased.

A further object of the invention is to provide a spooler in which the traverse rod is carried by rockers with means for varying the amplitude of traverse of the thread or yarn upon the spool.

Where it is desired to use spools of dif ferent lengths it is also necessary to vary the position of the points of reversal of traverse and a further object of the invention is to provide novel means by which the points of reversal of traverse may be properly positioned relatively to the base and head of the spool. T

Another object of the invention is to provide rack and pinion mechanism for reciprocating the traverse rod of the spooler, the means for driving the pinion including a changeable gear by means of which the amplitude and speed of reciprocation of the traverse rod may be varied for different spooling conditions.

Other objects and features of the inven tion will more fullyappear from the fol lowing description and the annexed drawings and will be pointed out in the accompanying claims. 7

In the drawings:

Fig. 1 is a partial front elevation, broken out to economize space, of a spooler embodying a preferred form of my invention;

Fig. 2 is a vertical transverse sectional view on line 2-2, Fig. 1, viewed from the righttoward, the left;

Fig. 3 is a plan view of the vertically re ciprocating rack. its guide, and showing also the bracket by which the guide is attached to the frame.

A preferred embodiment of my invention is illustrated herein as applied to a usual type of spooler such as that illustrated in my prior Patents Nos. 7 14,797 granted No-: vember 2 1, 1903, and No. 1,261,619 granted April 2', 1918, and comprises main supporting frames 1, 2, 3 connected near their lower ends by rods 4, and supporting at their upper ends rails 5 upon which suitable spool holders 6 are rotatably. mounted, the shafts of the spool holders 6 being provided with whorls 7 driven by suitable belts passing around the usual drum 8 which is mounted upon ashaft 9 extending longitudinally of the frame and provided with a driving pulley 10 of the ordinary character.

As is usual in spooling machines the spindles are arranged symmetrically upon opposite sides of the drum 8 and the traverse mechanism which lays the thread upon the spools is actuated simultaneously for both sets of spool holders.

Rods 11 extending longitudinally of the frame and suitably secured thereto support bobbin holders which comprise curved bases 12 to receive the bobbins attached" to stands 13 which are provided with U-shaped extensions l l clamped by set screws 15 to the rods 11. The stands 13 also have upwardly and outwardly extending arms 16 to which pairs of guards 17 are 'yieldably secured. The thread is led from the bobbins, which rest' upon the curved bases beneath the guards 17 and upwardly through thread guides which are clamped upon a reciprocating traverse rod 18, to the spool.

The thread guides preferably are in the form of loops 19 extending laterally. from clamps 20 fastened by suitable screws 21 upon the traverse r0d 18, the thread guiding portion 22 of the clamps being arranged horizontally. In order to prevent the wearing of a groove in the-thread guide by the thread which is being delivered to the spool,

' the traverse rod' is supported upon pivotal arms through which it is given a slight longitudinal motion in addition toits vertical traverse motion in the following manner so that "the thread plays back and forth along the horizontal portion 22.

As illustrated herein the rails are provided with oppositely disposed bearings for the journals of swinging or oscillating yoke-like members 24, the journals being disposed transversely of the frame so that the yokes are fulcrumed to swing between the side frames as shown in Fig. 2 of the drawing.

The yokes are provided with horizontal extensions'25 upon which are secured short arms 26 having laterallyand vertically offset portions 27 adapted to engage the under faces of rockerarms 28, which are pivotally supported. upon the extensions 25. The offset portions 27 of the arms 26 support and actuate the arms 28 and may be adjusted in relation thereto by suitable adjusting screws 29 whereby the height of the traverse rail cnts aforesaid.

In usual types of old construction the rocker is actuated through a drum which is alternately rotated in opposite directions. In such constructions the wearing and kinking of the chain at times interferes with the proper operation of the machine. The present invention is designed to eliminate this chain construction and to provide a rigid able actuating mechanism.

.9. the base of which is secured by bolts 39 to spool holder.

and positive means foractuating the rockers and also means for ad usting the position of the traverse rod relatively to the controlling or adjusting the speed and amplitude of traverse in order that the mechanism. may be employed to wind properly spools of different lengths.

In the embodiment of the invention illustrated one of the yokes 24l is provided with an additional lug or extension 31, on the opposite side to that illustrated in Fig. 2, which is connected to one end of a link 33,

= the opposite end of which is connected to the vertical arm 34 of a bell crank lever the other arm 35 of which is connected to suit- The bell crank lever is pivoted upon a stud 36 which is adjusta'bly mounted in a slot 37in a'bracket 38 the upright frame 3. The bracket also desirably'is provided with a downward exten sion i0- which engages one or both of the tie rods 4t. :By adjusting the fulcrum 36 of the It also includes means for bell crank lever in the slot 37 the position of reversal of traverse may be varied in accordance with requirements of different lengths of spools which are to be wound. In order to provide for a more delicate adjustment than could easily be made by adjusting the rod, desirably is actuated through mechanism which will be positive in its action and if po-ssiblefree from likelihood of breakage.

In the'present' invention a novel type of rack and pinion mechanism has been devised for accomplishing this purpose. The pre- 'ferred driving mechanism which is illustrated comprises a pulley l i upon the main shaft 9 which is connected by a belt to a pulley 46 mounted upon the end of a shafti7 which is'journalled at one end in a bearing upon the frame and at the other end in a bearing 48 at the end of a bracket 49 which is attached to and supported by the end frame 1.

The shaft 47 is provided with a gear 50 which meshes with a gear 51 carried by a shaft 52 having at its end a pinion which engages the teeth of a mangled gear 53. In order to provide sufficient lateral movement for said pinion to enable it to run first on the outside and then upon theinside of themangled gear, the shaft 52 desirably is mounted in bearings in a yoke 54 having .a stem'55 which is pivotally mounted in the bracket 49. I

The mangled gear isfixedly secured to a shaft 56 suitably journalled in a. bracket 57 carried by the vertical frame 2. The shaft 56 of the mangled gear. has secured upon it a changeable gear 58 which meshes with an idle gear 59 which is mounted upon a shaft 60, the end of which is carried in an arcuate slot in the bracket 57'. The idle gear. 59 meshes with a gear 61 which is mounted upon a shaft 62 carried by the extension of the bracket 57. The shaft 62 of the gear 61 carries also a.

pinion 63 which engages the teeth of a vertically reciprocable rack 64:. The upper end of the rack 64 desirably is formed in;

tegral with or connected to a cross head 65 preferably having a'T shaped cross section.

The flanges of said cross head are recipro=- cably mounted in grooves in a guide '66 having rearwardly extending lugs 67 which are secured by bolts 68 to brackets 69 which are connected to the frame 2. Another bracket desirably may be secured to the frame and provided with guards 71 and 72 overlying and forming a protective housing for the train of gears 58, 59 and 61. The bracket 70 also desirably is provided with an arm 73 having a guide 74 which embraces and rests against the side of the rack opposite to the teeth thereof and serves to hold the teeth of'said rack in engagement with the pinion 63. r

The cross head 65 is provided with an outwardly extending boss or lug 76 to which is pivoted the yoked end of an arm 77, the opposite end ofwhich is pivotally connected by a stud or pin 78 to the end of the bell crank arm 35. 'i

In the operation of the machine the pulley 1O drives the main shaft 9 and thereby rotates the drum which drives the spool carriers. Power is transmitted from the main shaft 9 through the belt pulley 44 to. the belt pulley 46 which drives the shaft 47 and pinion 50. The pinion 50, meshing with the gear 51, rotates the shaft 52 which carries the pinion which engages and r0- tates the mangled gear 53-alternately in opposite directions. This; alternately opposite rotation of the gear 53 correspondingly rotates the gear 58 alternately in opposite directions and the latter, through the train of gears 59, 61 and 63, reciprocates the rack 64 and its cross head 65. As the cross head '65 is connected by the link 77 with the arm 35 of the bell crank lever, each reciprocation ,of the rack and its cross head causes the oscillation of the arms 35 and 34 of the bell crank; lever which in turn transmits through the link 33 an oscillation to the yoke 24 and rocker arm 28, thus raising and lowering the tra' verse rod in the manner aforesaid.

When diflerent sizes of spools are to be wound the changeable gear 58 is removed and replaced by one of different diameter, the shaft 60 9f the gear 59 being suitably adjusted in a slot which is concentric with the shaft 63, thus enabling the proper cooperation of this train of gears. When a larger gear is substituted for the changeable gear 58 the amplitude of reciprocation of the rack 64 and its cross head is increased. Conversely, when a smaller gear is substituted for the gear 58 the amplitude of reciprocation of the rack and its cross head is correspondingly decreased Thus the amplitude of movement of the bell crank arms 35 and, 34 may be increased or decreased and the amplitude of movement of the traverse rod correspondingly increased and decreased to provide for the different lengths of spools.

Obviously when the amplitude of the traverse rod is varied it is necessary to provide suitable adjustments in order that the same may be properlycorrelated to the positions of the baseand head of the spoolsl Such adjustment may be'accomplishedb-y shiftmaintained in properly adjusted position;-
