CURLING-MACHINE.

Specification of Letters Patent.

Patented June 16, 1914.

Application filed October 21, 1913. Serial No. 796,442.

To all whom it may concern Be it known that I, ROBERT SUMNER, millmanager, residing at Cowley Pechey, Middlesex, England, have invented certain new and useful Improvements in Curling-Machines; and I do hereby declare the fol lowing to be a full, clear, and exact description of the invention, such as will'enable others skilled in the art to which it apper tains to make and use the same.

This invention relates to an improved machine for curling hair, horsehair, vegetable fibers, wool and the like material, the object of the machine being that the whole of the fiber or other material to be treated is delivered in a raw state at the one end, and is fed out twisted, kinked and curled as a rope on to a bobbin at the other end, ready for'the baking or similar process for permanently securing the kink or double curl after the same has been imparted to the material by the operation of the machine.

Now according to this invention a conveying belt and feeding rollers are so mounted that a continuous supply of material is fed to the periphery of a carding engine, which carries the material around for approxi mately one half of its circumference. At this point the felt of fiber on the carding engine is stripped by means of a rotating comb from which it is taken by a revolving brush, and delivered into a hopper conveniently placed relative to said'brush. Im-

mediately beneath the said hopper is disposed a revolving drum or box containing,

journaled in its sides, three or morepairs of grooved pressing rollers, placed underneath each other, but mounted in opposite angular directions. Beneath the last pair of rollers is a hollow twisting spindle, which may serve as a pivot for the revolving box. The material is fed through the hopper on to the first pair of rollers from'whence the now rough sliver passes between the succeeding rollers and through the twisting spindle, and in a twisted state, resulting from'the combined actions of the rollers, the rotating box and twisting spindle, the sliver is curled upon a hollow rotating coned spindle through which passes a string or cord for the purpose of receiving the now twisted and curled strands when leaving the hollow spindle. The said string or cord when relieving the spindle of its coils preserves same 111 the curled state and delivers them in such state to a suitable bobbin upon which the coils are wound. When the bobbin is full, the machine is stopped, the cord is cut, and the two ends on the bobbin tied together, the bobbin is now removed, a fresh bobbin inserted, and the operation continued. To permanently retain the curl now produced in the fiber, the bobbin is dipped in water, and baked until all moisture is driven out.

The invention will now be described more particularly with reference to the accompanying drawings in which I Figure l is a part sectional side elevation ,of-the machine, Fig. 2 is a transverse View on line AB, Fig. 1, and Fig. 3 is a view giving details of top driving gear.

In the drawings, 1 is the conveying belt conveying the material to the feeding rollers 2, which deliver said material to the carding engine 8. Said engine being of the usual construction comprises a rotating drum 1 provided with combing pins or cards 5, incased by a removable cover 6. In order the better to feed the engine the cover 6 is for a short distance on the inside provided with combing pins 7 said pins being arranged in staggered fashion relative to the pins on the drum. The material is carried around the engine for approximately one half of its circumference, at which point it is stripped by means of the rotating comb 8, consisting of a drum 9 provided with hooked pins 10. Said pins being adapted to enter between the pins on the carding drum thereby removing the felt from the carding engine. As the felt is carried around by the comb it is brushed off same by means of the revolving brush 11, and delivered into the hopper 12 disposed beneath the said brush. The carding engine is preferably driven from a suitable shafting by means of the belt 13 and the pulley 14, mounted on the engine shaft 15. Said shaft also carries the pulley 16 driving the brush 11 by means of belting 17 and pulley 18. The shaft 15 carries at its other end the bevel wheel 19 driving the bevel gears 20 by means of which are driven the conveying belt 1, feeding rollers 2, and the comb 8 as shown in Fig. 3. Shaft 15 further carries the pulley 21 driving the twisting device as will be described later. It is obvious that these various drives may be altered to suit diiferent circumstances, and the arrangement described above is given as a preferable method and by way of example only.

Beneath the hopper 12 is disposed a revolving drum or box 22, in which are contained three pairs of rollers, 23, 24 and 25, said rollers being placed in parallel planes beneath each other, but having the center pair mounted in a right angular direction to the other pairs as shown in Figs. 1 and V 2. Said rollers are each provided with a groove as shown at 26, said groove serving the purpose of shaping the silver in passing between the rollers. A hollow twisting spindle 27 mounted in the plate 28 (see Fig. 2) is disposed beneath the last pair of rollers in such a manner so as to serve as a pivot for the box 22 around which the said box may be rotated. The spindle 27 carries fast on same a bevel wheel 29 driven by means of bevel wheel 30 fast on spindle 31 journaled in bearings 32 and 33. The said spindle 31 is driven from the pulley 21 on shaft 15 by means of the belt 34 and pulley 35, or by other suitable means. The bevel wheel 30 also drives the wheel 36 which is fast on the box 22 thus rotating same. Inside the said box and secured upon the hollow twisting spindle 27 is the bevel wheel 37 which drives wheels 38 and 39 by means of which, and by means of the chain gears 40 and 41 the rollers, 23, 24 and 25 are driven as illustrated. Beneath the spindle 27 is disposed a rotating coned spindle 42 mounted on or formed with a hollow sleeve 43 journaled in bearings 44 and 45, and adapted to be driven from the pulley 46 on shaft 31. Over the spindle 42 rollers.

is mounted a fleeting knife 46 the action of which will be described later. The various mechanisms described above and comprised within this invention are preferably mounted within a suitable framing 47 which serves as support for the necessary shaft bearings.

The operation of this invention is as follows ;-After the material has passed through the carding engine 3, and the fiber felt stripped off the said engine and delivered to the hopper 12 as already described, the felt is fed on to the first pair of rollers 23 where it is formed into a rough sliver when passing over the groove formed in said The sliver becomes more and more definite in shape as it passes the succeeding rollers and it is firmly twisted into a strand when passing from the last pair of rollers to the twisting spindle 27 the twist being accomplished by means of the box 22 being rotated in one direction and the spindle 27 being rotated in an opposite direction. The twisted strand is now delivered from the spindle 27 to the coned spindle 42 upon which the strand is curled as the said spindle is rotated. When the spindle is full the 4 coils are continuously pushed oflf same by the fleeting knife 46, exerting a continuous pressure on the oncoming strand. From the spindle 42 the coils travel on to the hollow sleeve 43, and from thence on to a cord or string 48 stored on a reel 49 and passing through the said sleeve. The string 48 is led on to a bobbin 50 and wound upon same together with the coiled material passing with the string from the sleeve 43. The bobbin 50 is rotated by any suitable means but preferably from the bevel gear 30 as shown in Fig. 2. The rotation of the bobbin 50 may be controlled by means of coned pulleys in such manner that the speed of rotation may be equalized as the windings upon the bobbin increase. When the bobbin is full, the machine is stopped, the string 48 is cut and the end tied to the bobbin which is then removed and a fresh one inserted and the operation continued. The rollers 23, 24 and 25 are removable and may be replaced by others having grooves of different sizes in order to enable the machine to form slivers of different thickness. To permanently retain the curl now produced in the twisted material the bobbin with the material is dipped in water, and baked in an oven at a suitable temperature until all moisture is driven out, when the fiber has imparted to it an elasticity and springiness hitherto unattainable by other means. Such process however of rendering permanent the curl or twist imparted to the fiber is well known, and does not form any part of this invention but is described in order that the process of the machine may be the better understood.
