JOHN J. HAMPSON, OF LONDON, ENGLAN'D.

MACHINE FOB. FILLING OR LOADING FABRICS.

Application filed April 24, 1919.

To all whom it may concern:

Be it known that I, JOHN JAMES HAMP- soN, a subject of the King of Great Britain, residing in London, England, have invented certain new and useful Improvements in Machines for Filling or Loading Fabrics, of which the following is a specification.

This invention relates to machines for impregnating or loading fabrics such as cottons, twills and other materials with a filling of starchy or other liquid, the machines being of the kind that comprise a vat or tank to contain a supply of the filling liquid, devices for tensioning the fabric as it is fed to a set of relatively adjustable rotary rolls, by 'which filling is conveyed from the tank and applied to the material, and one or more ad ustably mounted doctors for removing surplus liquid from the fabric and pressing the filling into the latter.

The present invention has for its object to provide an improved machine of the above kind which is so constructed and can be so adjusted that the various impregnat= ing and loading operations of back filling, back filling and skimming in one process, light skimming, heavy slop filling or heavy starching, double stiffening, and single stiffening can be alternatively effected by it, each of which operations has at present to be carried out on a separate machine.

In a machine constructed according to this invention, there is a top or squeezing roll vertically adjustable in position and two bottom rolls adapted to convey filling from the tank and apply it to the fabric to be treated. The two bottom rolls which are independently adjustable in horizontal directions, are arranged tandem-wise, one on each side of, but at a lower level than the top roll. A doctor knife is so mounted on the frame of the machine that either it can i be placed in a position between the two bot tom rolls so as to press against the fabric passing between these rolls, either in or out of contact with the surface of the top roll, or the doctor knife can be withdrawn from between the bottom rolls to a position outside of the working zone where it. will take no part in a loading operation. Means are provided whereby, when the top roll is in use and the doctor knife is arranged and adjusted to press the fabric against that roll, as in back filling and skimming, the

knife will bear on the fabric with a yield- 1ng pressure that may be varied, and when the top roll is not in use, but the knife has to press against the fabric, as-for example 1n light skimming, the knife will be held in proper operative position by the said means. v Means are included for turning the two bottom rolls according to circumstances in either direction of rotation. The mechanism for driving the bottom rolls is so constructed that the gears fixed to the roll spindles for turning the rolls will always remain in mesh with the gears that drive them, no matter how far the rolls may have been adjustably moved apart or shifted relatively to the top roll.

In using the improved machine, considerable economy in time, labor and working ex enses results.

he invention will be described with reference to the accompanyin drawings in which Figure 1, comprising Figs. 1 and 1", is an elevation of one side of the improved machine in one of its forms.

Fig. 2, comprising Figs. 2 and 2" is a longitudinal section of part of the machine viewed in the same direction as Fig. 1, the machine being shown and adjusted for the combined opverations of back filling and skimnnng. igs. 3 to 7 are diagrammatic sectlons similar to Fig. 2, but to a smaller scale, showing the machine adjusted respectively for (a) Back filling.

(5) Light skimming.

(0) Heavy slop filling.

(d) Double stiffening.

(e) Single stiffening.

In the several figures the same parts are indicated by the same letter.

The machine is provided with three rolls 1, 2, 3 (between or over two or more of which the fabric, according to the operation to be performed, passes) carried in a suitable framework 4 and arranged for example as in Fig. 1 so that lines connecting their axes 1, 2'. 3 form a triangle, the two

lower rolls

2 and 3, whose axes are in the base of the triangle, being partly located in a tank 5 for the liquid or filling. The three rolls are mounted in bearings 1 2 3 respectively, which bearings are capable of being moved to and fro so that one or two nipping points may be provided between the curved surfaces on the rolls or whereby the rolls may be entirely separated. Two or more doctor knives 6, 7 are provided, knife 6 being mounted so thatit can be arranged to operate between the lower pair of

rolls

2 and 3, and so as to combine its action with the upper roll 1, and doctor knife 7 at the ex t side of the said pair of rolls. Each knlfe is adjustable in position for the purpose of varying the pressure exerted by iton the fabric or allowing it to be moved clear of same, as hereinafter described.

The knife 6 is clamped by means of a plate 6 and studs 6 to a carrying member 6 fixed to a spindle 6 the two ends of whlch are mounted in bearing blocks 6 arranged on each side of the machine. Each of these bearing blocks is mounted to slide in bracket guides 6 suitably attached to a part of the framework 4 and in a position inclined to the horizontal. Correlated with each block 6 by means of a screw thread connection is 1 member 15 which is fixed to a spindle 16 a rod 6 one end of which is rotatively mounted in the lower end 6 of the corresponding bracket guide 6. upper end of each rod 6 passes'through a cap piece 6 secured to the upper end of the bracket guide. The upper end of'each rod 6 carries a handwheel 6 or other device wherewith it may be turned. By turning the handwheels 6 and the rods 6 the blocks 6 can be shifted in one or other directions along the guideways of the bracket guides 6, and the doctor knife 6 made to approach or recede from the cylindrical surface of the roll 1 thereby varying or dispensing w th the pressure of the knife on the underside of the fabric 67 passing under the roll 1. By operating the hand-wheels 6 sufliciently the doctor knife 6 can, before the fabric is passed through the machine, be retracted from between the rolls to an inoperatlve po* sition above roll 2 and to the left in Fig. 1, of roll 1.

Means are provided for rocking the doctor knife 6 about the axis of the spindle 6 so as to vary its inclination. with respect to the fabric and its pressure thereon. Such means may comprise a link 8 (or there, may

be two such links, one on each side of themachine) having one of its ends detachably connected with an arm 6 carried by the work 4. If two links 8 be employed there will be two levers 9 which are operated for turning shaft 10 and thereby adjusting the inclination of the knife 6 with respect to The other or 1,s13,ese

tact with it, while allowing it to yield or turn about its axis to a small extent when meeting with joints or other irregularities in the thicknessof the fabric.

Suitable means may be provided for retaining the levers 9, when desired, in any adjusted-position. Such means may consist, for instance, of a pin 13 that is passed through a hole 9 provided in the levers, and,

through one or other of the holes 14 formed in one of the uprights 14 hereinafter referred to and supported by the framework 4. The knife 7 is clamped like knife 6 to a carrying height of the knife 7 with respect to the roll 3 can be varied by raising or lowering the blocks 17 by operating the screwed rods 19 that are in screw threaded relation with' the blocks 17 and have their lower ends mounted to turn in the lower end of the guide frames 18. The rods 19 traverse the cap pieces 18' and are furnished at their upper ends with hand wheels or other devices 19 wherewith they may be turned. Means, such as the arm 15, screw-threaded rod 20, pivotally attached thereto and passing through an opening in a part 22 carried by the framework 4, and a nut 21, may be provided for adjusting the inclination of knife 7 with respect to the fabric, and-thereby varying the amount of filling in the fabric.

. The

rolls

1, 2, 3 are arranged to be adjustable in position. In the form of the machine shown in the drawings the, bearings 1 of the upper roll 1 are Vertically adjustable in upright guides 23 by means of rods 24 which at the lower ends are attached to the bearing blocksl and have their upper portions screw-threaded and are correlated with nuts having the form of worm wheels 25 each of which meshes with a worm 26.

The worms 26 are carried 'by a transverse spindle 27 rotatably mounted at each end in brackets 28 carried by bosses 29 formed on levers 29 which are each pivoted at one end in supports 30 on the guide frames 23. Through the bosses 29 of levers 29 pass the screw threaded portions of the rods 24 and on their upper surface the worm wheel nuts 25 are seated. The other ends of the levers 29 are each pivotally connected to one end of a link 31 which by means of an adjustable screw coupling 31 at its other end is joined to a link 31' which in turn is pivotally attached to a lever 32 in turn pivoted at one end 32' to the framework 4, and at the other end carries an adjustable weight 32 It will 'be seen that by means of this arrangement the roll 1 is suspended, being carried by the pair of pivoted levers 29 which are controlled by the pairs of

adjustable links

31, 31. The Weights 32 carried by the levers 32 can be adjusted to plaeeany desired pressure on the roll 1. By virtue of this arrangement roll 1 will, when it meets with any undue pressure, rise and yield to the pressure but will subsequently return, when such pressure ceases, to the normal or initial position under the action of the weights 32 and associated parts.

The spindle 27 is provided with some convenient device, such as a crank handle, wherewith it and the worms thereon may be turned so that by the co5perative action of the screw rods 24 and worm wheel nuts, the bearings 1 and roll 1 may be raised or lowered. Or the spindle 27 and Worms 26 may be manually operated, as shown, by means of a chain 34 passin around a sprocket wheel 35 fixed to the spindle 27 and a similar wheel 36 rotatably mounted on a spindle 36' carried by a frame 90 hereinafter referred to and carried by the framework 4.

- Studs 33, screw-threaded into the lower portion of each guide frame 23, serve-to regulate the descent of the bearings 1 in the guideways. The mechanism for driving roller 1 from the main driving shaft 37, as described below, is arranged to permit of the adjustments or movements described above, a drive in either direction and also the discontinuance of the drive at any time. The wheel 36 if desired may be fitted with a handle 36 for turning it.

The lower rolls 2 and 3 are adjustable to and from each other, which may be arranged by mounting their bearings 2' and 3' to slide in horizontal guideways 38 in guides 38.

The bearings are moved along the guideways by means of the screw rods 39 and 'worm wheel nuts 40. The worm wheel nuts 40 can be turned by means of the worms 41 keyed to spindle 42 which would be provided with. suitable means, such as the crank handle 43, for operating it.

Any suitable mechanism, however, which will permit of a sliding adjustment. preferably by hand, and a drive in either direction from the main drive and a disconnection from the main drive of either roll or bowl may be employed.

The roll 1 is driven from the main driving shaft 37, on which are mounted fast and loose driving pulleys 44 operated from any suitable source of power. Shaft 37 carries a toothed wheel 45 in gear with a toothed wheel 46 which is adapted to operate a wheel 47 keyed to the shaft 1' of roll 1. The wheel 46 is carried by a stub shaft 46' adjustably mounted in a curved slot struck from a point on the axis of shaft 37 and formed in a bracket supported from the framework 4, so that the necessary adjustment of the position of wheel 46 can be effected, when the roll 1 is raised or lowered, by moving shaft 46 along the slot.

The

rolls

2 and 3 are also driven from the main driving shaft 37 by means of mecha:

nism which permits of the rolls being adjusted in the manner above described and a reverse drive of either of the two

shafts

2, 3 when desired, while they are in any position. Such mechanism, as shown in the drawings, may include a pair of bevel wheels 48 loose on shaft 37 and in mesh respectively, at diametrical opposite points, with a bevel wheel 49 on the lower end of a vertical shaft 50 mounted in bearings 51, carried by a bracket 52 which is fixed to the framework 4, and a clutch device 53 mounted to rotate with shaft 37 and to slide along a feather thereon. The clutch 53 is slid along shaft 37 by means of two arms 53' which are yoked at one end to the member 53 and at their other end fixed to a spindle 54 which is supported in bearings carried on brackets 55 attached to framework 4. The spindle 54 and clutch member-53 are controlled by the hand lever 56 fixed to the end of the spindle which is turned in one direction or the other so that the member 53 clutches one or other of the bevel wheels 48 accordin to the direction in which shaft 50 is to be riven. The upper end of shaft 50 carries a bevel wheel 57 which meshes with a bevel wheel 58 fixed to a keyed or feathered shaft 59. To each of the

shafts

2 and 3 is keyed a bevel wheel 60 and with each wheel 60 there meshes a bevel wheel 61 capable of sliding along a key 01' feather on shaft 59. Each of the wheels 61 has a hub 61 on which is formed a groove in which fits the bifurcated end of a yoke piece 64 which at its other end encircles the roll shaft 2' or 3 as the case may be. It will be seen that as either the

roll shaft

2 or 3 and the corresponding bevel wheel 60 are moved in a guideway 38 the corresponding yoke piece and engaged bevel Wheel 61 will be likewise moved so that the bevel wheel 61 remains in mesh with the bevel wheel on the roll shaft thus moved.

The tank 5 is provided, as is customary, with one or more power driven agitators for the liquid. Two

such agitators

62, 63, are shown in Fig. 1. They may be of wood and of rectangular or other design. They are mounted on the transversely disposed spindles 62 and 63' appropriately journaled in the sides of the tank. These spindles are provided each at one end with a pulley or sprocket wheel 62 63 over which a belt or chain runs. On the other end of the spindle The fabric 67 is arranged to enter the machine over a fixed tensioningrail 68 and one or more tensioning bars or rods 68 which latter are carried by the uprights 14 above referred to. The fabric then preferably passes either over further fixed tensioning bars 'or rods or, according to the treatment to be carried out, through a tensioning frame which may, as shown, consist of a pair of pivoted disks 69 carried by the two uprights 14 and connected together by tension rods 70, about which the fabric passes. Suitable -means may be'provided for turning the disks and the rods carried by them in one direction or the other so as to vary the tension on-the fabric. The disks are provided on their peripheraledges with holes in whlch a tongue 71 on a pivoted pawl 71 can be placed to hold the tensioning device n an adjusted position. The machine may be provided with a second tensioning device which consists of the bars or rails 89 which are carried by a bracket 90 on each side of the framework 4.

72 is a draw roller attached to a spindle 73 journaled at each end in bearings mounted on brackets '74 supported from the guide frame 23. This roller is adapted to be rotated by means of a pulley wheel 75 mounted at one end of spindle 73 and a belt 76 which also passes around a pulley wheel 77 keyed to the main driving shaft. 78 and 79 are rollers adapted to draw the loaded fabric passing over guide roller 72 toward mechanism, not shown, for folding or plaiting the fabric. The roller spindles 7 8 and 79 are carried in suitable bearings 80 and 81 bolted to an appropriately supported member 82 associated with the said plaiting mechanism. Roller 78 is adapted to be driven from the spindle of roller 79 by means of the pulley wheels 75' and 78 and belt 83,-while roller 79 can be driven from i the spindle of roller 78 by means of pulley wheels 7 8 and belt 84:.

85 is a guide roller which is carried by two blocks 86 one on each side of the machine, each block bein adj ustably mounted to slide in a guideway 8 on a bracket 87, supported on the framework 4 when the screwthreaded 1 rod 88 is operated.

If the operation to be carried out is that of back filling, the rolls are adjusted so as to be separated apart as in Fig. 3 and the fabric 67 after passing through the tension devices may pass over the first of the lower rolls, above the first doctor knife which presses it against the under side of-the upper roll 1 to remove the surplus starch or other liquid. and then passes out over the draw roller 72 for plaiting or other purposes. In this case the lower roll may be driven in the reverse direction 'to the upper as indicated by the arrows on the rolls-in Fig. 3. For back filling and skimming as illustrated in Fig. 2, allthree rolls 1, 2 and 3 may be driven in the same direction and the fabric may pass over both lower rolls and both'doctor knives 6 and 7, the first of which exerts pressure on the fabric from the under side against the upper roll, while the second on the exit side of the last lower roll may exert pressure on the under side of the fabric without any support for the fabric above.

' The fabric in this case may conveniently pass out over the adjustable guide roller 85.

For light skimming, Fig. 4:, the upper roll is not employed, the two lower rolls being driven in the direction of travel of the fabric, which is in contact with the upper portions of, the rolls, the first doctor knife 6 pressing against the under surface of the fabric, but not pressing the latter against the upper roll which for this purpose has been moved away from the fabric.

I For heavy slop filling or heavy starching, Fig. 5, the three rolls are moved into nipping contact as shown; the lower rolls are driven in the direction of the fabrics travel while the upper roll 1 may or may not be driven and the fabric passes around the second lower roll 3 and under and partly around the upper roll, the doctor knives 6 and 7 being preferably moved out of action. For double stiffening, Fig. 6, the arrangement of the three rolls is the same, but the fabric travels under the upper roller only and over the two lower rolls. In this case the tension device comprising the bars or rails 89 is brought into use, in lieu of or in addition to the

tensioning device

69, 70.

For single stiffening, Fig. 7, the upper and first lower rolls only are in contact, the uper being free to revolve and the lower being riven in the direction of the fabrics travel, the second lower roll being moved out of contact with the fabric which passes, as for double stifiening, between a lower and the upper roll.

In none of the last mentioned three arrangemen-ts need the doctor knives be used, though one or more of the tension devices would be.

Other variations of the position of the rolls, the drive of the same, and the amount of pressure (or absence) of the doctor knives are possible, according to the amount of starch or other liquid it is desired to incorporate in the fabric, and a drive of a lower roll (or rolls) may be arranged in the reverse direction to the travel of the fabric incorporating more starch or the like into it.

Having thus described the nature of the said invention and the best means I know of carrying the same into practical effect, I claim 1. In a filling'loading or impregnating machine of the class specified, a lurality of rolls, one'of which is above the ot ers and all having'means to permit them to be moved toward and from each other, a filling tank in which a part of the rolls operate, and doctor knives adjustably disposed in a lane between and at a distance from the ro ls to carry on either of the respective operations of back filling, back filling and skimming, light skimming, heavy slo stiffening and single stiffening in a unitary machine.
