Patent GB-484897-A (GB)
Title: Improvements in or relating to apparatus for treating fibrous materials with liquid
IPC: D01G29/00
Filed: 1936-11-26
Abstract: The delivery of liquid, such as oil, to fibrous textile material to be treated, such as wool, is controlled by a tipper arranged to receive and discharge successive measured quantities of the <PICT:0484897/IV/1> <PICT:0484897/IV/2> <PICT:0484897/IV/3> liquid to a container from which it is delivered as a substantially continuous spray.  The tipper preferably has two compartments and is so arranged relatively to the liquid supply that when one compartment receives liquid the other is discharging it.  The tipper tilts under gravity but may be held by catches which are released in accordance with the operation of gravity-actuated devices for feeding the fibrous material, to proportion the quantities of liquid and material.  A number of tippers of different capacities may be provided and used singly or in combination, as desired, and these may be released in accordance with the operation of the receptacles so that the liquid is supplied in proportion to the material.  The tippers 18 may be mounted upon a single shaft 20 and each may be divided into two parts 18a, 18b by a partition.  Each is so arranged that liquid flowing from a tank 14 through such cocks 19 in the base thereof as are open, is received in one or other of these compartments.  Surplus liquid overflows through notches 18c in the sides to a compartment 21c in a tank 21 from which it drains to be pumped back to the tank 14. Liquid is emptied, when the tipper tips, into one or other of two compartments 21a, 21b of the tank 21 whence it flows via a pipe 25, through V-notches 28 in a header 26 extending across the machine to an apron plate 27 tangentially arranged relatively to a roller 29, the film of liquid on which is sprayed by a revolving brush 32.  If only small quantities of liquid are to be supplied, an auxiliary tipper 23 may be brought into operation by opening the cock 24 to discharge liquid idly to waste to ensure the necessary tilting effort to the shaft 20.  The fibrous textile material may fall from a hopper 10, Fig. 1, into which it is fed by an elevator 9, into that one of a number of receptacles 1 which happens to be in receiving position under the hopper.  These receptacles 1 are carried by a shaft 2, which is extended at one end and carries a disc 5, Fig. 5, provided with a number of pins 6 corresponding in number to the receptacles 1, and these pins are engaged in succession by a weighted lever 7 which tilts under the weight of material in that receptacle which is held in receiving position, to discharge the material on to a conveyer 11 by which it is carried past a treating station. Paddles 12, carried by an extension of the opposite end of the shaft 2 and moving in an oil bath 13, serve to damp or steady the rotation of the receptacles 1.  Instead of the receptacles 1 being mounted on a single shaft, they may be carried on a flexible conveyer movable in an endless path under the weight of the fibrous material to be treated.  In order to limit the operation of the liquid supply means, a finger 33 carried at one end of the shaft 20 may be retained by one of a pair of pivoted catches 34 to hold the assembly of tippers 18 in either of their tilted positions.  Such catches may be released in unison with the movement of the receptacles 1 by upward movement of a tappet 37 against a spring 39 produced by a bell-crank lever 41 which is connected by a flexible cable 50 to a slidable member 46, a pawl 45 on which is engaged by a trigger 44 on one end of the weighted lever 7, as that lever returns to position, to engage a succeeding pin 6, after it has been tilted by the discharging operation of one of the receptacles 1.  By adjusting the position of a weighted rider on the lever 7, the weight of wool required to turn each receptacle may be regulated.  If desired, in order to increase the maximum proportion of liquid which may be applied, additional pins 6 may be provided. Release of the finger 33 may alternatively be effected by electromagnetic devices when a circuit is closed by movement of the lever 7 by a pin 6.  Instead of producing a liquid treating spray by a revolving brush, nozzles may be employed.  Specification 484,820 is referred to.
