Beit known .that I, WILLIAM GHRIsTo- IIIER :MoLoUeHLIN, a subject of the King of vGreat Britain, .residincrat No.V 369 Smith street, VFitzroy, in the tate of Victoria,

' affalse twist vto the sliver for strengthening 4with the tube f4. l Thehinge -fB of f lis so `arranged that the weight'of f will keep it Commonwealth of Australia, have invented :certain new.. and useful Improvements in Spinning-Machines,'of which the following is a specification.

lThis invention has been devised to provrvideda machine whereby the spinning of fabrics will 'be more effectively.' and 'expedr :tiously' accomplished than at present.

describing my invention, Ishall refer to the lspinning of what is known by those skilled in the art, as .condensed woolen yarn,y `thel individual fibersiof which have beenlbroken up in the condenser into the required slivers, the latter being drawn out or drafted during such step in the manufacture. 4'The fibers are straightened, equalized, and combined, being finally wound on a bobbin in an attenuated, but `strong uniform condition,-

providing. a yarn suitable for the desired purpose. Y

. In ordervthat my invention maybe the more easily understood, reference will be made to the accompanying drawings, in

which- Figure l isa general* View of a machine with apparatus.embodying my invention... For sake of clearness, many of the duplicatefparts of themachine have, for operation at the rear, been omitted. wSoIneof also been omitted for the same purpose.

. der which the sliver. passes, while -.fF`g.s. L] andill areprespectively sectional 1 the parts at thel frontv of the machine have Fig.;8is an enlarged. view of a tubular l sure is such that it will not prevent the .provided comprising preferably four standards a braced together by front, rearl and sidebars a. I) and b arranged in any convenient manner within the frame. On the top of the latter isthe usual differential gearing b2 receiving motion by an endless belt running on pulley wheels b,the operating power being transmitted from a main shaft b3," the gearing actuating the longitudinal feed rollers and carriers (hereinafter described) running at pre-determined speeds as hereinafter referred to.

The sliver c is fed from the spool c', the spindle 02 of which rests loosely on the diagonal arms c3 fixed in any convenient manner to the sides of the frame. s From the feed roller 04 the sliver c passes downwardly, and in doing so, goes through the fingers (Z of the wire guard d secured to a block Z2 on one of the frame bars a. The sliver passes from the fingers d between the roller c and carrier e", the latter being mounted in bearings e2 and driven by the gearing Z22 *hereinbefore mentioned. The sliver c in its forward movement receives a twist to increase its strength for .winding purposes, and the construction hereinafter described holds it should it break between the feed, roller e andthe bobbin thus preventing it becoming entangled between the feed roller c and carriers e and the gear, before the operating power is shut off. e v l .The construction comprises two arms f mounted on the bar a of the` frame, one at each side, said arms f connected by a cross strap at the rear of which is 'disposed a parallel strap f2, both straps held together by bolts f3 and form bearings for a rotary tube f4 with pulley f5. Theproj ecting end of the upper portion f (see'Fig. 8) being fixed to an armfl" hinged to'a block 7" integral continuouslyin Contact, ror nearly so,-with the underhalf f of the tube ff.. The -presksliver c .sufficiently to increase its tensile strength, thereby. greatly reducing the pos Y l710 to, and passed through the ring jg, which directs it on the curved edge 7c3` of the bell sibility of a break while traveling between the carrier h and the bobbin. Y

The rotary tubes f4 yreceive their motion through an endless belt g (see Fig. 7) arranged to pass over the pulleys)15 and tliewf tension pulleys g and the drum b4 on the main shaft The tension pulleys y are mounted on a spindle g2 carried by an adjustable'arin g3 supported in a shaft g4 running in bearings (not shown) iii the side bars b. The tension or load is adjusted by the weights g at the end of the arm gl.

From the mouth of the tube f4 the sliver c passes between a carrier 71, (see Fig. l) and a tension roller h mounted oiian` arm h2 hinged to the rear parallel stay bar f2. The sliver c passes from the tension roller to a high speed rotary retarder or flier j preferably constructed of wire and bent to the required configuration, preferably with a U-sha'ped top portion. j or ring jl@ forming director fingers and horizontal pieces i2 one of which has a ring js at its end.

The retarder or flier j rotates in a bearing at the top of a stationary shroud hereinafter described, the bearing consisting of a screw bolt j* with a central vertical slot (see Fig. 3) in which rotates the vertical supporting piece jc having at its bottom an enlarged cone shaped formation j?, acting as a stopper, and running in a circular shaped recess js provided at the top ofthe stationary shroud fz (see'Fig. 3).

The sliver c passes from the carrier h to,

' and under the U-shaped or ring portion j and jl the former forming fingers for lead-- ing purposes, and the latterfor the same purpose also. The sliver c is led from j or mouth 7a2 of the shroud 72.

' To obviate undue vibration, and also to Y reduce the tension of the sliver c during the winding process, the retardei or flier is weighted at the end j providing` a counter balance effect against the strain placed on the other or ringed end Fixed vertically on the head of the spindle lo is a shroud or bell Z1 of a hollow circular formation, the lower end 7a2 being bell mouthed, its circular rounded edge 7c3 acting as a directoi or guide to the sliver c to insure an even and parallel winding of the sliver c on to the bobbiii. rllhe latter is in the form of a tube 'in with a pulley m atits bottom end, and is loosely mounted on the stationary spindlelc. A stationary circular block m2 Which is supported by thebar 0 formsfa boss upon which it rotates. The

vspindle lo is xed to a horizontal bar 05 securedto the'front of the frame, and forming part of the movable carriage hereinafter described.V The bobbin receives its motionv through an endless belt n arranged to pass around each vof the pulleys m and tension Y pulley m3 and the drinn b4 mounted on the main cross shaft 63 (see Fig. 5).

The tension of the loadV is regulated by a weight m4 on the bell crank m5 mounted on the shaft g4. The shaft runs in bearingsV fixed on the side bars 0 of the frame. Any

suitable power may be employed to actuate the main shaft b3 and the drum b4.

The carriage comprises upper and lower cross bars 0 and 0', the former having a shelf 02 attached for required purposes The bars o and 0 are connected to movable side guide rods 03 operating vertically in Vguide blocks o4 integral with the standards of the frame. The movement of the carriage is regulated so that as the sliver is wound around the bobbin, the latter becomes wider iii diameter, and the winding point of the sliver,`on the bobbin is raised or lowered accordingly, This action is accomplished byproviding for a vertical movement of the carriage, and also controlling the extent of such movement.

lThe carriages receive their vertical movement through the differential gear and carrier, the latter'forming a shaft at the end of which'a worm gear p is provided, actuating a toothed vWheel p on aside shaft p2 running in bearings p3 in one of the standards of the frame and side bars 5. Y

Mounted on one end of the shaft p2 is a cam 1 which in its rotary movement actuates a rod 1", the top end of which operates in a bracket p4 integral with the' bar b.

The rod 0 imparts motion'to a lever rod hereinafter referred to.- The rod 1" is provided with a handle r2 to reverse the rotary motion of the rod r when it is desired to lower the carriages to remove a bobbin and insert a fresh one on the spindle lo.

The lower end ofV the rod 7V is screw threaded and engages a. block r3 attached to a lever rod 7* hinged to one of the standards (i of the frame. The lever rod rf, in turn, operates the cord or cable?15 passing over the pulley wheel 1 on the shaft W running in suitable bearings (not shown), on the lower bar of the side bars o.

Mounted on the cross shaft W are pulley wheels rs and r from which cords or cables 710 pass, their lower ends being fastened to the bottom bar 0 of the carriage.

Simultaneously with the vertical movement of the front carriage, a vertical movement is imparted to the rear carriage, a cord or cable s being employed oneend being conveniently secured to the wheel 7'8 and passed over a -pulley s, its end being. Afastened to the lower bar 0 of the rear carriage.

the end ofthe shaft 292.V The disk has` awr-l number of adjustable strikers s3 adjusted according to the required speed of the shroud and bobbin. This regulation of speed is accomplished by causing the strikers S3 to come into contact at a pre-determined time with a ratchet lever t, the return movement of which is controlled by the spring t. One end of the ratchet lever t is provided with a spring locking pawl t2 which engages the teeth of a ratchet wheel t3 within the bracket p4, the wheel 153 is keyed to the rod 7" by a key t4 passing through the boss t5 of the wheel t3 into a vertical key-way t6 in the rod r. This arrangement permits a vertical movement of the rod r simultaneously holding the ratchet wheel t3.

A second spring controlled locking pawl a in the block a is employed to retain the ratchet wheel t3 at the end of each of its semi-rotating movements. The bent Wires u2 are employed as a handle when it is required to operate the pawls t2 and u by hand.

I would have it understood that some of the parts may be amplified or modified to suit the various sizes of machines or the class of work to be performed, and the material to be treated.
