Definitions

  • the solvent which is generally of a light volatile nature, as benzene, or carbon tetrachloride, or trichlorethylene, may then be 16 freed from its foreign matters by a distillation and condensation process in a well known manner, so that it may be used over and over again in the cleaning operations.
  • the object of the present invention 1s to 20 provide a construction of apparatus by which there is combined with the cleaning or washer means, distilling and condensing means for restoring the cleansing solvent to its purified condition, and to provide that the supply of solvent to the washer and the dlscharge of solvent from the washer is effected automatically and continuously throughout the working of the machine.
  • Such discharge is designed to be effected to the distilling means when a pre-determined amount of solvent collects in the washer, while the supply of solvent to the washeris effected from the condensing means acting in conjunction with such distilling means.
  • the invention consists in a special construction of apparatus of this combined nature by which a self contained unit is produced that occupies a relatively small amount of floor space, and embodies the aforesaid automatic charging and discharging of the cleaning solvent into and from the washer chamber.
  • Figure 1 is a front elevation of the combination, the casing containingthe washer operating gear being shown open.
  • Figure 2 is a sectional side elevation of the 50" machine.
  • Figure 3 is a sectional elevation of a suitable form of siphon for use in the machine.
  • a washer chamber 10 is provided and such is furnished with the usual re rindments in this class of apparatus under w ich a door covered opening 11 is made in the front for the insertion and removal of the articles to be cleaned, and a glass covered inspection opening 12 is also made in the front. It is also provided with a dolly, or beater, 13 of any known design for operation upon the articles placed within it through the up and down movements of a vertical spindle rod 14 to which it is attached and which passes out through the top of the machine for connection with the actuating mechanism, hereinafter more fully referred to.
  • Y dolly, or beater
  • the washer chamber 10 has combined with it a bottom chamber or still v15 which may be made in one with the washer chamber as in the drawings, or separate therefrom so that the washer chamber fits over its top to enclose it.
  • the bottom 16 of the washer chamber is covered on its underside with a layer 17 of a suitable heat insulating material to prevent the heat from the still 15 being communicated to the washer chamher.
  • the still 15 is itself heated by means of any suitable and convenient heating agency, as for instance by the gas burners 20 arranged in a heater space 21 situated beneath.
  • the still is also fitted with a drainingtap 22,
  • a siphon fitting is shown in Fi res 2 and 3, and comprises a vertical tu e 24 the lower end of which screws into a ring 25 let into the washer bottom 16, and a hood 26 covering the upper end of the tube and extending down round movement of the washer or agitatin it to near the bottom.
  • the tube is made with perforations 27 near its upper end so that iquid may pass up between the tube and the hood and in through these perforations to pass down the tube and through the ring 25, into the lower end of which a pipe 28 is screwed to lead the liquid into the ottom of the still.
  • the tube is suitably made to form a liquid tight joint in the ring 25 and thus will effect the siphoning of the washer chambers liquid contents into the still when the level overflows through the holes 27 on a well known principle.
  • the tube 24 is made with a hole 29 near its lower end, which normally is closed by the screwing of the tube into the ring 25, but which may be opened by partially unscrewing it to raise the hole above the ring. An li uid then in the chamber bottom will t ere y be free to drain away into the still.
  • a condensing chamber 30 is positioned above the top of the washer chamber 10 and may form a top therefor, such chamber in turn being covered by a cover plate 31, havin a bearing 32 through which the spindle r05 14 passes upward.
  • 'A condenser coil 33 is arranged within the chamber 30 and such is connected at one end by the pipe 34 with the top of the still 15 and at t e other end opens down into the washer chamber 10. Any approved cooling medium is caused to as through this chamber 30 so that cleansing liquid vaporized in the still 15 and passing therefrom and through the condenser coil 33 will be condensed into liquid form and flow into the washer.
  • Such disc has a crank pin 43 on one 'face on which a sprocket wheel 44 is mounted.
  • a second sprocket wheel 45 is mounted in the casing at a position vertically above the top of the rod 14.
  • a sprocket chain 46 has one of its ends fastened to the top end of the rod 14 and is then carried up over the sprocket wheel 45, down round be- Death the sprocket wheel 44 upon the disc crank, and then upward again and has its other end made fast to the top of the casing.
  • a weight 47 (Figure 2 may be mounted on the rod, such. weig t be- 1ng supported upon a spring 48 which will serve to absorb any jars or shock on the fall of the rod. The weight and its spring, however, will not be required if the articles being treated are suspended in a basket upon the rod bottom. An slackening of the chain 46 during the.
  • Rotation is imparted to the disc spindle 41 from an electric motor 50 arranged upon the machine top, the s indle 51 is coupled to a s indle 52 mounte to extend across within t e casing 42, and having a worm 53 thereon which ears with a worm wheel 54 fixed upon the iso spindle 41.
  • the level at which the liquid will be siphoned from the washer chamber to the still may be'provided for and altered at will by having slphons of different heights that are interchangeable with one another. This'will rovide for economy in the use of the cleanslng solvent as ensuring of the correct amount required for different articles being employed. ,7 Articles treated in this washer, on removal, will be treated in the known manner for the extraction of the liquid with which they are charged.
  • I claim Dry cleaner a paratus comprising in combination, a was er chamber, a still having means for heating it arranged. beneath the washer chamber, a connection between the washer chamber and the still, formed by a siphon fitted into the bottom of such chamher and opening into the still, and a condenser arranged upon the top of the washer chamber and embodying a cooling coil one end of which isrconnected to the top of the still while the other end is arranged to enter the washer chamber,
  • a condenser arranged upon the top of the washer chamber and embodying a cooling coil one end of which isrconnected to the top of the still while the other end is arranged to enter the washer chamber
