ABMAND CHARLES FREY, OF SOULTZ, FRANCE' VISCOSE-DISTRIBUTING DEVICE FOR ARTIFICIAL-SILK PLANTS.
Application filed March 30, 1927, Serial no. 179 679, and in Switzerland March 31, 1926.
In devices used for the manufacture of artificial silk, the viscose is fed, to the spinning nozzles either by means'of ordinary pumps or by toothwheel-acting pumps intended for adjusting the amount of viscose to the required quantity that should be delivered.
The present invention has for its object a viscose-distributing device designed after the known principle of the toothwheel-acting pump, that is to say, the-viscose flowing under pressure is fed to one side of the teeth of said wheels wherefrom it is next passed in determined quantities to the other side, to be then transmitted to the spinning nozzles.
The backlash in these parts on account of their unavoidable wear, is eliminated, in most devices, through the provision, either for one of the toothwheels or for both, of a crescent-shaped distance-piece inserted between the teeth of the wheel and the inner wall of the pump casing, said distancepiece being continuously acted upon by an elastic pressure tending to force it between the wheel periphery and the casing wall.
Now, all of these devices are subject to a drawback in that they allow of no actual regulation in view of increasing or reducing the quantity of viscose to be fed; after all the result aimed at lies in automatically eliminating said backlash due to wear of the parts. As, furthermore, the distancepiece thus introduced between the toothwheel and the housing wall uninterruptedly exerts a braking action between them, these devices are subject to a rather considerable wear at these points, on account of which they cannot serve the purpose after a certain time of working.
The present device is free of any such drawback. It comprises the employment of a crescent-shaped distance-piece likewise intended for avoiding the gap due to play or backlash of the parts as a result of wear,
but so arranged that saidgap, and, therefore, the amount of viscose fed on, can be, at will, either reduced or amplified, according to whether said viscose is in a more or less diluted state. Adjustment of the feed is operated from outside and can be efi'ected with the accuracy required for bringing the quantity of viscose up or down to any predetermined rate of delivery.
The object of this invention has been shown, by way of example, in the accompanying drawings, wherein:
Fig. 1 is a longitudinal section of device;
Fig. 2 a sectional view through the central part wherein the two toothed wheels are located;
Fig. 3, a side view, in the assumption of a removal of the cover; and
Figs. 4 and 5 show said cover, by a side and a plan'view respectively.
The two spur- Wheels 4 and 5 are enclosed in a housing made of three parts, say a flanged bearing 1, a central member 2 and a cover 3. Said toothed wheels mesh in one another free of any ,gap, and they are so exactly executed as to cause wheel 4 to come in contact with the surrounding housing wall of the middle member 2 sub'ect to no play whatever. As to wheel 5, which, as can be seen, is not guided by a shaft, it is lodged eccentrically inside the cylindrical recess 6 hollowed out of the crescent-shaped member 7, which is movably located, in a corresponding recess 8 of the central member 2. .Itwill be readily understood that any rotatory move ofsaid crescent-shaped member 7 will bring about, dueto the ece centrical position of wheel 5, an interval of play not only between the teeth of the two wheels, but likewise between the wheel 5 and the inner cylindrical wall of recess 6, and that, by rendering the gap wider or narrower, an exact regulation of its width will be possible.
Regulation of this gap will be accomthe plished by means of the peg 9, which is rotatably mounted in the cover 3, and is provided with an eccentrical stud 10 at its in ner end, this stud 10 to enter as a tenon in the slit 11 provided inside the crescentshaped plate 7, thus allowingto havesaid plate 7 moved on or back whenever the head 12 of peg 9 is turned one way or the other.
' A graduated scale 13 has beenprovided upon the head 12 of said regulating peg 9 whereby it is possible to ad ust its position I with respect to a mark 14 branded on the cover 3; besides, a set-screw 15 serves to fix said peg 9 in the position it has been thus given. I
The wheel 4 is driven by the worm-wheel 16 fixed upon the shaft 17 which latter is connected with the shaft 19 of toothwheel 4 by means of a coupling 18.
The viscose fed under pressure will enter at 20 into the device and will thus arrive, through opening 21, within reach of the spur wheels 4 and 5 which will drive it to the opening 22 wherefrom it will be led through the opening 23 to thespinning nozzles.
If, for any reason, such as wear of the movable parts,.the amount to be fed must be modified, it willbe sufficient to unscreyv the set screw 15 and to turn the head 12 one way or the other so as to have it adjusted with respect to the mark 14, a regulating operationwhich can be effected without ever stoppin work, and which requires but a" few secon s. .I claim:
A gear wheel pump for distributing viscose in artificial silkv plants comprising in I said second spurwheel is eccentrically lodged; said crescent-shaped member being freely l dged in a circular recess inside said casing, anda peg rotatably mounted in the pum casing and ending with an eccentrical- 1y p aced studxengaging a. slit formed in a the outer periphery of the crescent-shaped member, substantially as described.
In testimony whereof I signed hereunto my name.
