CARDING MACHINERY.

Application filed May 5,

As is well known, cotton carding machines have to be stripped from two to four times per day depending on the amount of cotton carded per day and the grade of the same in order to do good carding. When stripping a card you stop the cotton in lap form from feeding into the machine and proceed to strip the cylinder and doffer by means of stripping rolls or a vacuum stripping system of all cotton and other foreign matter which has become embedded in the wire cloth on the cylinder and dofi'er. Heretofore in the art after the stripping operation has been completed the feed roller is started so that the cotton lap is fed into the card wherein the cotton fibres are combed or carded and are delivered by means of the doffer or coiler head into a can which is placed in front of the machine. It has been found however that when starting the machine up after the stripping op eration the weight per yard of the first few yards of sliver is very light owing to the fact that a great deal of the cotton which is fed into the machine is being pressed into the wire clothing of the cylinder and thus is utilized to charge the cylinder and is not taken therefrom by the doffer. As soon as the cylinder fills up or has become charged the weight per' yard of the sliver taken therefrom by the doffer reachesthe average weight for which the machine is set to produce but this correct average weight is not produced until about fifty yards of sliver has been delivered from the machine after the stripping operation. Such light weight and non-uniform sliver makes very uneven and a very poor grade of yarn. For example, it has been found that where the average weight per yard of the sliver pro duced under ordinary operating conditions before stripping was fifty-nine grains with a variation in weight of four grains per yard, the weights ranging from fifty-seven 1923. Serial 3T0. 636,917.

to sixty-one grains per yard on a sixty-yard test then after strlpping card machine, the

first yard delivered weighed thirty-two grains and forty-eight yards were delivered before the machine reached fifty-eight grains. It will be noted from these findings that'the first yard delivered after the stripping operation with the ordinary machine will run about forty-five per cent light.

The object of the present invention is to provide an automatic sliver evener adapted to be oragnized with carding machines and which when so organized is effective to overcome the aforementioned difficulties and disadvantages and to enable the carding machine to produce a uniform and highgrade' product as well immediately after the stripping operation as durmg normal operation.

For instance wlth the same mach ne whose performance has been noted above but after havin OI dIIlZGCl therewlth the automatic sliver evener constituting the present inven:

tion, the weight of the first yard delivered after the stripping operation was found to be sixty grains with a variation in weight per yard of two and one-half grains in a twenty yards test, the lightest weight per yard being fifty-seven and onehalf grains.

" hen the automatic sliver evener constituting the present invention is in' use the weight per yard runs more evenly immedl V-ately after stripping than it does with the ordinary machine ordinarily equipped when operating under normal conditions.-

A further object is to provide a device of this character, and having the foregoing advantages and which is also of simple and durable construction, reliable and efficient in operation and adaptedto be organized with;

conventional card'ag machinery without.

necessitating serious or. expensive .altera tions.

Other objects and advantages of the invention reside in certain novel features of the construction, combination and arrangement of parts which will be hereinafter more fully described and particularly pointed out in the appended claims, refer: ence being had to the accompanying drawings forming part of this specification and in which: 7 1 Figure 1 is a diagrammatic view, in plan, showing the relation of the automaticsliver evener constituting the present invention-to certain of the machine;

major elements of a carding 1 Figure 2 is a fragmentary and diagrammatic view in side elevation of a portion of the carding machine equipped with the present invention;

Figure 3 is a view in side elevation, showing the automatic mechanism whereby the feed roll is driven from the dofl'er or is driven independently thereof;

Figure 4 is a view in section taken approximately on line 1- 1 of Figure 3 and looking in the direction of the arrows;

Figure 5 is a view in rear elevation of the parts of the invention shown in Figure 3, the view being taken looking to the right end of Figure 3;

Figure 6 is a detail perspective view of the keeper bar for the automatic shifting lever; and

Figure 7 is a detail view illustrating the connection of the hand lever and sleeve of the automatic shifting mechanism.

Referring to the drawings it will be seen that the carding machine is shown diagrammatic'ally and it is to be understood that it may be of any conventional construction. In the drawings it is shown as including a frame 5 upon which is mounted and suitably driven a main cylinder 6; At the rear end of the machine is a lickerin 7 and a feed roller 8 and atthe front end of the machine and cooperating with the main cylinder is a doffer 9; The main cylinder, licker-in, feed roller and doifer have shafts 10, 11, 12 and 13, respectively, which it is to be understood are suitably journaled on the frame 5 and project at their ends beyond the frame.

The licker-in 7 is driven from the shaft 10 of the main cylinder 6 by a cross belt 14 trained over pulleys fixed to the shafts 10 and 11. Means is provided for driving the doffer from the licker-in and includes a gear Wheel 17 secured to the shaft 13 and adapted to be driven from a pinion 18 fixed to one end of a short shaft 19. The short shaft 19 is rotatably mounted in a bearing prov ded in a depending bracket 20 integral with a Vertically swinging arm 21 on one end of which arm 21. is pivotally. mounted, as at 22, on the frame 5. A hand lever 23 is suitably mounted on a bracket 24 and cooperates with the free end of the arm 21 and controls its position and incidentally controls the engagement or disengagement of the pinion 18 and gear wheel 17. The short shaft 19 which has fixed thereto the pinion 18 also has fixed thereto a pulley 25 driven by a belt 26 from the licker-in. This arrangement thus far described is conventional and standard in all respects.

'Means is provided for driving the feed roll from the shaft 13 of the doifer cylinder when desired and preferably the feed roll is driven from the shaft 13 of the doffer cyl inder at all times except during the period which follows immediately after the stripping. For this purpose a shaft 30 is pro vided and has one end geared, as at 31, to the shaft 12 of the feed roller 8. ()n the opposite end of the shaft 30 from that which is geared to the feed roll 8 a sleeve is mounted so as to be at all times constrained to rotate with the shaft 30 while free to be shifted longitudinally or axially with respect thereto. In order to efiect this mounting (see Figure 3) the sleeve 32 is slotted longitudinally, as at 33, and in the slot 33 a pin 3% is received, the pin 3% being fixed to the shaft 30. Obviously other means may be employed for so mounting the sleeve 32 on the shaft 30. One end of the sleeve has secured thereto a beveled gear wheel adapted to be brought into mesh with a coacting beveled gear wheel 36 fixed to the shaft 13 of the doii'er cylinder on the end of this shaft 13 opposite from the ring gear 17. When the

gears

35 and 36 are in mesh the feed roll 8 is driven from the doifer 9. l/Vith the present invention it is proposed to drive the feed roll independently of the doii'er immediately after the stripping operation, the doifer being allowed to remain stationary whereby the main cylinder may be charged or filled up to the requisite depth to obtain sliver of proper weight. In order to carry out these purposes a large gear wheel 38 is also fastened to the sleeve The

gear wheels

35 and 38 are spaced from each other and their hubs 35Pand 38" define an annular groove 37 between them, the function of which will hereinafter fully appear. hen the sleeve 32 is shifted in one direction on the shaft 30 as for instance to the left as viewed in Figure 3, the

beveled gears

35 and 36 will be disengaged and the large beveled gear 38 will be brought into engagement with a small beveled gear 39 fixed to a vertical shaft 4-0 adjacent the upper end thereof. The vertical shaft 40 is mounted at its lower end in a spindle bear ing 41 and at its upper end it is rotatably mounted in a bearing 42 provided in a bear ing bracket 43 secured to the frame 5, as shown in Figures 3 and 4. The vertical shaft 40 is driven from a jack shaft 45 extending transverselyacross the machine by beveled gears 16 to provide for a speed reduction, the jack shaft 15 being held for rotating movement, as at 47', in the frame and carrying at its end opposite the vertical shaft aw a large spur gear wheel 48 wh ch is so disposed that the pinion 18 is adapted to be brought into mesh therewith. It will thus be understood that the pinion 18 is selectively engageable with either the gear wheel 17 of the doifer cylinder or with the spur gear wheel 48 of the jack shaft so that the motion received by the pulley 25 from the belting 26 may be transmitted to the doffer cylinder or may be transmitted through the gear wheel l8, jack shaft 45,

lot!

- thereto a two part. clamp, one of the parts of' gears 46, vertical shaft 40 and

pinions

38 and 39 to the shaft 30, from whenceit is transmitted to the feed roll. 6

Shifting mechanism is provided for controlling the engagement. of the

pinions

35 and 36 and 3S and 39 and this shifting mechanism preferably includes a hand lever 50 pivotally mounted, as-at 51, to a bracket 52. The portion of the hand lever 50 pivotally 'mounted on the bracket has secured thereto and movable therewith a-lateral arm 53 upon which a weight 54: is adjustably mounted. In order to provide forth'e connection of the hand lever to the hub 37 and consequently to the sleeve 32 a collar 55 is loosely mounted in the annular groove 37 and has secured the clamp 56=carrying a lateral pin 57 which is fitted-in an opening-58 provided therefor in a hand lever 50; The arrangement is such that the

gears

35 and 36 may be disengaged by a manual shifting of the hand lever '50 and of course. by such shifting the

gears

38 and 39 are engaged but when however the

gears

38 and 39 are'to be disengaged and the

gears

35 and 36 engaged the operation is entirely automatic. For this purpose the lever 50 has fixed thereto a spring dog 60 cooperable with teeth or notches 61 provided in an arm 62 carriedbythe frame extension. As shown in Fi'gure 6 the notches 61 have inclined faces 61 and vertical faces 61 so that the lever may be shifted to the left as viewed in Figure 3 without interference from the spring dog since it snaps over the inclined walls 61 of thenotches. Reverse movement jof-the lever, that is a movement fromyleft' to right, as viewed in Figure 3- can only be had when the spring dog 60 has been pressed away from the arm 62 and thereby withdrawn from the notches 61.

Automatic tripping or releasing mechanism',-,is provided for releasing the spring dogl60 that is for retracting it from engage ure 3. -This releasing mechanism includes a shaft 65 rotatably 'mounted in bearings provided on the frame extension and arm 62 and having fixed to one end. thereof a large gear wheel 66 meshing with a small gear wheel 67 fixed on'a oountershaft 68 rotatably mounted on the frame extension. The countershaft 68' also has fastened thereto a large gear wheel 69 with which a small gear wheel 70 fixed-to the sleeve 32 is adapted to engage when the

gears

38 and 39 are engaged and the gears'35 and 36 are disengaged that is when the gears are shifted to the left as viewed in Figure It is to be'noted that the gearing between the pinion 70 (which being fixed to the sleeve 32 is thus indirectly fixedly connected to the'shaft 30) and shaft 65 'is'of such ratio as to very materially.re=

duce the speed of the shaft 65 with respect to the shaft 30 so that the shaft 65'turns very much more slowly than the shaft-3O and consequently very much more slowly than the feed roller. In order to permit of the necessary variation in the relative speeds of the shaft 65 and the feed roll the countershaft 68 is mounted in an adjustable bearing in the frame extension asindicated at 71, in

Figure 4: so that various sizes of gears 67' and 69 may be employed. A cam is loosely mounted on the shaft 65 and includes a lateral and longitudinally extending finger 76 at its periphery engageable with the spring dog 60. An actuator 77 is'provided for the cam and is secured to the shaft 65 by a set screw 78 and is provided with a laterally extending pin- 79 engageablewith the cam 75 to rotate the same with the shaft 65. The cam 75 is held against longitudinal displacement in one direction by the actuator 77 and is held against longitudinal displacement in the opposite direction by a collar 80. 'VVith this arrangement the shaft 65 and consequently the shaft '30 and feed roll can partake of considerable'rotation while the feed roll "is being driven independently of the doffer through the

gear wheels

38 and 39 79 engages the cam 75 to rotate the same and the cam can be so located on the shaft relatlve to this actuator that it passes through a part or the whole of another revolution be- ,fore its. pm 76 presses against the spring dog 60 to retract the same and permit the weight.

5 1 to disconnect the gear 38 from the gear 39 and to bring the

gears

35 and 36 into mesh and thus to drive. the feed roll. The disengagement of the

gears

38 and 39 is accompanied'by the disengagement of the gears 69 and 70 since the gears 70 and 38 are carried on the same sleeve.

Braking mechanism is provided for stopping the shaft 65 as soon as the pinions 69 and 70 are disengaged and thus holding the cam and its actuator in its proper position ready. for the next operation. This braking mechanism includes a braking element 85 slidablv mounted on the arm 62 and connected to the hand lever 50 by its apertured lug lug 86. Nuts' 88 areithreadedly connected with the rod 87 andengage the lug 86 onthe opposite sides thereof whereby adjustment may be made to secure. the desired degree of braking action and to compensate for wear.

When' it is desired to carry out the stripping operation the hand lever 23 is raised so that the swinging arm :21 is lowered and the pinion 18 is disengaged from" the gear.

.uWllBBl 17 of -the defier whereby' the-feed roll is stopped since the drive is transmitted to the feed roll through the dotl'er in the normal operation of the machine. When the dofler is being stripped the hand lever 50 is moved to the left, as viewed in Figure 3, and is engaged with the middle notch of the arm 62, the spring dog 60 looking the arm 50 in such position against retrograde movement. lVhen the stripping operation has been completed and normal operation of the machine is to be resumed the hand lever 50 is shifted to the extreme left hand position as viewed in Figure 3 so' that its spring dog 60 engages in the third notch 61. This shifting of the arm 50 brings the

gears

38 and 39 into engagement so that the feed roll is then driven from the pulley 25 through the

gears

18 and 48, jack shaft 45, beveled gears 46, vertical shaft 40 and beveled

gear Wheels

38 and 39. The feed roll then operates to feed the cotton to the main cylinder but the doffer is not operated to take the cotton from the cylinder at this time. Moreover when the feed roller is so operated it is moved very slowly for it is being actuated through the speed re duction and thus the cotton is fed at a low rate of speed into the card so that the card has more time in which to spread the cotton into an even sheet adapted to uniformly charge the cylinder. During this time the shaft 65 is also being driven though more slowly than shaft 30 and the cam actuator 77 is being rotated around into engagement with the cam so that subsequently and at a time when the main cylinder has been properly charged the cam will be actuated and its finger 7 6 pressed into engagement with the spring dog 60 to move the dog out of its notch 61 thereby releasing the lever 60 and permitting the weight 54 to move the lever 50 and consequently the sleeve 32 to the extreme right as viewed in Figure 3 so as to bring the

gears

35 and 36 into mesh and so as to disengage the

gears

38 and 39. The hand lever 23 is then lowered to raise the arm 21 and move the pinion 18 out of engagement with the pinion 48 into engagement with the gear wheel 17 so as to drive the doffer from the pulley 25 and drive the feed roll from the doifer as in the normal operation of the device. With this arrangement the carding machine may be stripped as often as found desirable and at the same time a high grade product is obtained for the sliver is of uniform and requisite weight and quality. A guard for the gears .69 and 66 is mounted on the bracket 43.
