7 Claims: (01.. 19-423) 1 This invention relates to new: and improved wool combing machines,. particularly of the Nobleitype, these machinesbeingrelatively large and:heavysin construction-and; embodying a large pinzcircleand twossmall pin:circles, incooperation with a veitical high-speedreciprocating brushy. preparing the: wool for combing .as disclosed in Patent No. 1,845,351, February 16, 1932, this patent disclosing improvements in the roll adjustment; and. attention is :also directed to Patent No. 1,026,058, Mayrl, 1912, for further disclosures. of. prior art machines. of the type herein. referred to.

In the prior art ithasbeen customary to drive the above referred 1 to brushrby; outboard means adjacentthe circumference-of the large pin circle from an overhead driven shaft,- the vlatterin turn beingdrivenirom a main shaft and having. a belt shifter approximately.- at-.the: center of the large pin circle andabove thesame-wherebythe operator is forced-to stop.an-d.start=the-machine by leaning .over the mechanism of the. machine in "order. to graspthe beltshi-ppfir; al opriorm machines have been.cu-mbersome andv hardto service due .to the.relative-..complexity.and sturdiness .required ,ina machine of this type, and it is a principal'ob'ject of thepresentinvention to. clearly improveandat'the same time simplify the driving mechanism for thepin circles, the rolls and thebrushes, at the same time greatly increasinglthe speed of the machine and the .output thereof while at the same time observing .and retaining the advantages 'derived'in the. inventions disclosed'in the above. referred. to patents.

Further objectsof'the invention include the provision of improved means :for liftin'gth'e upper portions of the drivingmeans without "disturbing the'lower portion of the" machine or any parts of the wool' combing apparatus; jtheprovision of improved means for driving, the brushes "soas to greatly facilitate servicing; assembly, etc, there-- of; and the provision in general of improved drivingmeans'for a wool combing machine of the class-described.

Other objects andadvantages of-the invention will appear hereinafter.

Fig. 4 is-asection on line-'4=--4 of Fig; 3;

The. combing machine... of s the: type disclosed herein comprises a' base generally indicated at It; this base being circular and relatively heavy as it carries the entire combing mechanism, driving means, etc. Adjacent the periphery thereof the base lil oarries a circular ball race 12 on which is rotatably mounteda large pin circle plate I4 modes is well known the large pin circle plate M rotates at a relatively slow speed on the base Hi in substantial tangency to'a pair of small pin circle plates l6.

Appropriate driving means is arranged to drive these plates at thesame circumferential speed, this driving means being largely below the top surface of the base I0, i. e., below the web or base top [8 of Fig. 2. Such driving means is conventional and well known and illustrated in Fig. 1 by the-broken lines which illustrate gears 20, 22, 2t, 26, 28. These gears form a gear train from gear 36 on the main shaft 32 for drivingv the large and small pin circle plates and the wool combing rollers, which rollers are more particularly described in the above identified Patent No. 1,845,351. It is to be noted that the two main shafts 32 are alike and the two small pin circles are duplicates and each performs the same operation as the other, doubling the capacity of the machine. Theoretically it would be possible to. go on multiplying these small pin circles to increase. the capacity of the machine, but practically such a scheme does not work out, it having been found that the double pin circle arrangement is the best.

Wool combing roller is driven by gear 28 and thegear 2 3 drives a pair of-gears'36 each separately driving a spur gear 38, 40- respectively, the latter driving the large pin circle plate M, the gear 38 drivingthe small pin circle plates IS. The above description shows briefly the complete drivingv means .for themachine except for the brushes to bedescribed below; but the brush drive is above the table top l8 whereas the remainder of the machine drive is below the latter, and this invention has to do mainly with the driving mechanism above the table topl8.

Each small'pin circleplate I6 is mounted'to 'rotate on a stationary support 62 which may be bolted to the table ltfand inside the support 42 which'is preferably circular, a column or pillar 44 is bolted to the table top as by a fiangedli. The pillar 4 5 receives thetop end of shaft 32 which terminates adjacent the flange in a clutch member 48. A corresponding clutch memberfifl is'fixed to the bottom of a vertical shaft 52 rising within the pillar and journaled as shown in Fig. 3 terminating in a worm wheel 54. This worm .wheel is engaged by a-zworm 56 on a cross 3 shaft 58 journaled in the sides of a box 60, the latter being mounted on and forming a part of the pillar 44.

Shaft '58 extends out of the box in a general direction inwardly toward the central axis of the entire machine and is provided with a pulley 652 over which is trained a belt or belts 64 running up to a pulley 66 on the drive shaft of a motor 68. All of this mechanism is duplicated as at the other end of the motor and like reference numerals have been applied to like parts thereof.

The worm shaft 58 is provided with a pulley or sprocket Hi driving another shaft 12, shaft 12 likewise being journaled in the box 60 parallel to shaft 58 and extending outwardly of the box 69 oppositely to the extent of shaft 58, terminating in a clutch member 14. Cooperating with clutch member 14 there is a separable clutch member 16 mounted on a shaft 18, the latter being journaled in a detachable plate 80 having flanges bolted as at 82 to the pillar Ml which extends above the box 60 a at 84. Thus it is seen that the base 80, shaft l8 and clutch part It forms an attachment which is easily dismounted from the machine for servicing, repair, and inspection, etc., and it is to be particularly noted that the drive means for shaft i8 is completely inboard relative to the pin circles so that the drive therefor is completely protected and the operator of the machine i protected therefrom. This particular drive clearly improves and makes more positive the prior art outboard belt driven mechanisms used heretofore.

Shaft 18 may be provided with a fly wheel 8% if desired, but in any case, the main purpose of shaft 18 is to vertically reciprocate the brush 88 which is shown in down position at the right side of Fig. 2 and in up position at the left side thereof, this brush being positioned just above the tangent point of the large and small pin circles, which tangent points are indicated at 913. Any mechanism desired or convenient may be utilized to reciprocate the brush from shaft l8 and in the present case a counter-weighted cam crank 92 is utilized for this purpose. All of the mechanism for the brush drive is mounted in a housing 84 in turn mounted on the plate 89 so that the entire brush mechanism forms a single unit easily attached and detached from th pillars 44.

The motor 68 is mounted on a bridge 96, the same being supported at its ends on the boxes 84 which form the uppermost parts of pillars M and this construction provides a strong and rigid mounting for the motor, the gearing and the brushes. At the tops of boxes 84 there are provided pivoted rings 98 on pins 188 which rings may be utilized for the attachment of cables so that the entire drive mechanism above table IS, with the exception of the pin circles, is easily elevated upon removal of the bolts holding flange 46 to the table 18.

In the operation of this machine, the boxes Hi2, see Fig. 1, guide the wool in ropes to the pins I04 of the large pin circle and the brushes 88 pound the wool down into the pins at the tangential point 90 so that the wool-combing rollers 34 may perform the combing function in the usual manner.

The present invention provides a positive drive for all the part of the machine, such drive having been clearly simplified over the prior art and made much easier to control by reason of the new driving mechanism including the electric motor; the new drive mechanism has resulted in the capability of the machine to be driven at a much higher speed without vibration and the drive is better protected from the entrance of dust and dirt than in the prior art.

The present invention also provides a machine in which the drive parts are largely housed with the exception of belt 54, the latter however being well within the confines of the machine and in fact approaching the center thereof where it is not necessary for the operator to extend his hands due to the fact that the motor 58 is easily remotely controlled; most of the driving parts may run in oil and the machine is longer lasting and runs longer and faster and with less vibration without the necessity of being taken down or serviced in any way.
