Application July 19, 1946, Serial No. 684,724 Y 9 Claims. l

The present invention relates to a'spinning machine, and particularly a spinning machine for individual or home use, wherein bers to be spun are drafted from the hands of the operator, as distinguished from automatic industrial spinning machines where the bers are fed by drafting rollers or other automatic means, the product of the present invention therefore being in the nature of true home-spun yarn or thread having the individual characteristics of this type of material.

An object of the invention is to provide a spinning machine of this type which is power driven by an electric motor or the like, and wherein the moving parts are so balanced and so supported in anti-friction bearings, that they may be rotated at relatively great speed, without excessive vibration, to the end that the home or individual production of thread or yarn may be carried on profitably, with a relatively great volume of production in comparison with time and eifort spent by the operator.

Another object is to provide a spinning machine wherein the speed of rotation of the yarn twisting yer may be under the constant control of the operator, so that the tension of the thread and the twist may be controlled according to the spinning technique of the individual operator, to the end that the product will have the individuality of home-spun material.

A further object is to provide an improved type of iiyer of enclosed form and preferably in the form of a cone, whereby improved balance in the yer is obtained and the thread is maintained in a substantially constant position Within the flyer and is prevented from ballooning.

Another object is to provide a spinning machine wherein the bobbin upon which the spun thread is wound is rotated by the iiyer through the pull of the tensioned thread extending from the flyer to the bobbin. A further object is to provide improved drag means acting on the bobbin spindle, whereby the drag may be conveniently increased or diminished as desired, the increase in drag causing an increase in tensionrof the thread and an increase in the relative winding speed of the thread as compared to the number of twists imparted thereto by the flyer, while decrease inthe drag causes the relative winding speed to be decreased. It is particularly proposed to provide l drag means consisting of a weighted band extending about a pulley and which permits small Weights to be conveniently added or removed as desired. Such weights may, for instance, be added during the winding of a single bobbin in order to compensate for the change in tension resulting from the building up of the thread on the bobbin, the tension being greatest when the bobbin is of relatively small diameter and decreasing as it increases in diameter. Thus by adding weights as the diameter of the bobbin increases the operator may maintain a substantially constant tension between the flyer and the bobbin.

A further object is to'provide a spinning machine wherein the working parts are of relatively simple construction and are conveniently accessible, so that the machine may be elfectually operated by blind or other partially incapacitated persons. Y

With the above and other objects in view, embodiments of the invention are shown in the accompanying drawings, and these embodiments will be hereinafter more fully described with reference thereto, and the invention will be finally pointed out in the claims.

Similar reference characters indicate corresponding parts throughout the several figures of the drawings.

Referring to the drawings and more particularly to Figs. 1 to 5 thereof, the spinning machine, according to the illustrated exemplary embodiment of the invention shown therein, comprises a rectangular frame It formed of channel iron strips provided with a pair of longitudinally extending channel iron beams I I-I I and transverse channel iron bracing beams I2-I2. Supporting legs I3 are provided at the corners of the frame, being inserted and secured in drilled block members I4 welded or otherwise suitably secured within the frame. Y Y Y At the forward portion of the frame there is mounted upon the-longitudinal beams lI-II the motor housing I 5, secured at its base to the beams by means of bolts I6, and having mounted upon its upper side a pair of longitudinally aligned bearing blocks I'I-I 'I provided with roller or other suitable anti-friction bearing units I8-I8 in which the tubular spindle I9 of the flyer is rotatably engaged. An electric motor 20 is mounted within the housing I and is provided with a pulley 2l connected by a belt 22 to a pulley 23 secured upon the spindle I9 forwardly of the forward bearing block I"I..

Upon the rearward end of the spindle there is secured a flyer 2t, in the form of a hollow cone, preferably formed of relatively light metal, and provided at its divergent open end withan inwardly extending rim flange 25 having a series of equally spaced eye-openings 2o therein, the thread adapted to extend through one of these openings to the bobbin, as will hereinafter more fully appear. The eye-openings are provided at equally spaced points in order to accurately balance the weight of the flyer.,

Upon the rearward portion of. the frame there is mounted the bobbin supporting stand,V consisting of a pai-r of leg, members 'il-27, secured to thev longitudinal beamsA II-II by means of bolts 28, and supporting upon their upper ends a U- shapedV bracket member 2S having a horizontal base and vertical bearing, supports at eachend, the base being secured upon the upper ends of the leg membersl by means of bolts 3%. In. JrheV vertical end supports therey are provided axially aligned circular openings 3l in which a tubular cylindrical shaft 32 is. engaged for forward and backward reciprocating movement, this shaft being supported withinthe opening-sby means of radial-ly dis-posed 1ro-llerY wheels; 3.3 carriedby 'an-- gula-r bracket members 34 mounted for inward and outward adjustment in radial slots 35 provided in the bearing supports, the bracket members 313 having slots 35 there-in eng-aged by clamping screws 31 to secure the adiust'ed position oi the roller wheels. This mounting provides for free reciprocate-ry movement oli the. shaft and permits it to be accurately aligned withv the flyer.

A pulley 38 is secured to the spindle. I9 between l,

the rearward bearing block I:'I and' the flyer, and is connected by a belt 3S to a pulley 5D mounted upon the end of the shaftv 4i ot a reduction gear unit di?, the base ci is secured tothe longitudinal beams IIII b-y means of bolts 43.

The other shaft M of the reduction gear unit is connected by a coupling d5 to anintermediate sha-it le which is in turn connected by a coupling il to a camshaft le mounted in suitable vertical-ly adjustable ball-bearing units lg-ee secured to the legs 27-21 of the bobbin supporting stand, the legs having vertical slots 5G-5l] through which the cam shaft extends. A cam 5I is secured upon the cam shaft, its camgroove 52 being engaged by a roller 53 provided upon a shait 54 secured toy a collar 55 rigidly mounted upon the tubular shaft 342A by means of a set screw 5S, the shaft '54 extending through a longitudinal slot 51 in the base of the bracketmember 29. The cam groove 5? is so plotted that uniform reciprocating rectilinear motion i-s imparted to the shaft In the respective ends of the tubular shaft 32 there are provided ball-bearing units 58 and 59 in which is rotatably engaged the rotatable bobbin spindle shaft Eil, this shaft having upon its forwardly projecting reduced-diameter end a threaded stud BI upon which the bobbin supporting stem B2 is engaged, and having secured upon its rearwardly projecting reduced-diameter end a drag pulley 63.

The stern 62 is provided with U-shaped spring members 64-64 engaged through slots 65-65 therein, for frictionally retaining upon the stem the tubular bobbin spool 66, the latter being in the form of a cylindrical tube formed oi cardboard or other suitable material.

The drag means for engagement with the drag pulley S3 comprises a band member 61, which may be in the form of a fabric tape, and which has removably engaged upon its depending end weight members 68, of any suitable form to be readily engaged or disengaged, one convenient form being, for instance, a weight of C-shape, which enables it to be readily slipped on and off the tape. If desired, a receptacle may be suspended upon the end of the tape into which pennies or other suitable weights may be placed, as desired.

In operating the machine, a length of spun thread A is tied or otherwise secured to the spool 66 and threaded through one of the eyelets 26 and through the tubular spindle I9. Thereupon the motor is started, causing the flyer to rotate, the cam 5B being simultaneously turned through its pulley and gear connections with the spindle l5? to cause the shaft 32 to reciprocate inwardly and outwardly. This causes the bobbin spool to move into and out of the cone-shaped flyer, so that the spun thread is wound thereon from end to end as it is formed. The bobbin is rotated through the pull of the tensioned thread, imparted thereto by the rotation of the yer, the drag created on the bobbin causing the flyer to rotate a relatively greater number of revolutions than the bobbin to thus cause the thread to wind on the bobbin. By increasing or decreasing the drag the relative winding speed is increased or diminished as desired', so that the desired twist and tension may be maintained by the operator. It is pointed out that at the start of the winding operation the relatively small diameter of the bobbin creates a relatively increased drag and greater tension on the thread, and as theY diameter increases this drag and tension decreases'. Hence, by adding weights to the drag band ill, a sub-- stantiall'y uniform drag and tension may be maintained. The cone-shaped flyer maintains the thread extending therethrough in a substantially constant position and eiectually prevents it from ballooning through centrifugal force. Conse quently, there is no danger of a ballooning thread becoming entangled with other parts of the machine.

The speed oi they motor is preferably controlled by a foot operated rheostat or variable resistance control unit indicated diagrammatically at 69. Thus, as the pedal of theV control member is pressed, the speed is increased or diminished as desired.

In Fig. 6 there is illustrated a modified form of the invention in which the motor 26P- is mounted upon a stand [5e in co-axial relation to the yer, the tubular Spindle Iiia of the lyer constituting the shaft of the motor. The spindle and flyer are thus directly driven by the motor, without thel necessity for the pulley or other drive means, and without the necessity for additional bearing supports for the spindle. The cam 5i] for operating the bobbin is driven from the spindle Il!a in the same manner as in the rst embodiment of the invention.

In Fig. 'l there is illustrated another modified form of the invention, wherein a separate electric motor I0 is provided for driving the cam 5,0,

the cam shaft 48 being provided with a spiral gear 'H engaged by a spiral pinion 12 secured to the motor shaft. The starting and stopping and speed control of the motor is synchronized with that of the motor a by connecting the two motors in parallel to the control unit E9.
