  • the present invention relates to: a. device for producing relative movements between a liquid. and articles immersed in the same. More: particularly, the invention relates to devices in which a. swingabl'e body is submerged in the liquid and oscillated therein by suitable exciting means, preferably with frequencies within the sonic or supersonic range.
  • Devices of the general type, above referred to, are employed for instance for washing of articles such as china'ware' and silverware, for washing of laundry, for washing or dyeing of fibers and. textile fabrics, for the extraction and solution of substances, in connection with electrolytic processes, etc.
  • One of the objects of the present invention is to provide a novel and improved device of the general type, above referred to, which is simple, sturdy, and compact in design and which can be inexpensively manufactured.
  • Another object of the invention is to provide a novel and improved device which can be directly placed upon the bottom of a vessel containing the liquid or be detachably secured to said vessel.
  • Another object of the invention is to provide a novel and improved device by which powerful and efiective relative movements between the liquid and the articles to be treated are obtained.
  • Another object of the invention is to provide means which coact with an oscillating body so as to improve the efiect of the movements of the same upon the articles to be treated.
  • Another object of the invention is to provide means for increasing the relative movements between the liquid and the articles, thereby increasing the effect of said relative movements upon the articles to be treated.
  • Another object of the invention is to provide a device in which the articles to be treated are-subjected to the combined effect of the movements of the body relative to the liquid and of gas bubbles formed within the liquid. It has been found that such'combined elfect greatly improves'the result obtainable with a device according to the invention, as will be more fully explained hereinafter. 7
  • the exemplified device according to the invention is shown as comprising a lower portionwhich includes the body to be oscillated and an upper portion which includes the means for imparting oscillations to the said body and feeding a gaseous medium to the device.
  • the device should be visualized as being inserted during operation in a container containing liquid and articles to be treatedso that the oscillating body is submerged in the liquid while the exciting means are above the highest possible level of the liquid.
  • the oscillating body is shown as a substantially rigid or stiff hollow closed body 1 which is preferably lentil-shaped and may be made of sheetmeta-l.
  • Body 1 is secured to one end of a tube 2.
  • the other end of the tube is attached to the armature 3 of an electromagnet.
  • This magnet comprises an iron. core and an exciting coil 4.
  • Armature 3 is arranged in a conventional manner;'it is capable of oscillating in response to an energization of the coil with a suitable current.
  • the electromagnet is preferably energized with alternating current of 50 cycles per second.
  • the coil is connected to a source of current by means of a cable 5, the inner connections of the electromagnet being conventional.
  • the electromagnet is disposed within a housing 6 made ofmetal or any other suitable material, the cable 5 being extended through the side wall of the housing.
  • the electromagnet can be mounted within the housing by any suitable means.
  • a sleeve 16 which guides the magnet core 15 and is held in position by a ring 17 and one or more bolts 18'. The latter also serves to secure a cover 1 9 to the housing.
  • the device further comprises one or more diaphragms, two diaphragms 7 and 8 in form of metal discs being shown.
  • Tube 2 is passed through the center portion of the diaphragms and secured thereto by any suitable means.
  • the peripheral margins of the diaphragms are attached to housing 6 directly or by means of a sleeve 20.
  • this sleeve is held between sleeve 16 and a shoulder 21 of housing 6.
  • the diaphragms serve to guide tube 2 and to close the housing space within which the electromagnet is located.
  • the diaphragms will participate in oscillations imparted to the tube 2 and also amplifying the same to a certain extent.
  • the device can be placed upon the bottom of the liquid containing receptacle (not shown), by providing a tube 9 extending from housing 6 coaxially with tube 2.
  • the lower end of tube 9 supports or is integral with a frame structure 10.
  • This frame structure surrounds body 1 in a basket like manner and is provided with feet 36 made for instance of rubber.
  • a substantially rigid intermediate wall 25 is disposed within housing 6 between the bottom thereof and diaphragm 8.
  • Wall 25 is formed with one or more transverse apertures 26 therethrough and secured with its outer rim to the wall of housing 6.
  • a flexible disc 27 made for instance of rubber is secured to wall 25 by any suitable means such as rivets 28.
  • One end of disc 27 abuts tightly against the outer wall of tube 2 and the other end overlaps the apertures 26 so as to form a valve with wall 25.
  • Air is admitted into housing 6 through inlet openings 29, preferably disposed adjacent to apertures 26.
  • the interior of the housing communicates with tube 2 through one or more outlet openings 30.
  • the lower end of the tube is open at 31.
  • diaphragm his caused to oscillate in response to an energization of the electromagnet.
  • an oscillatory movement in the upward direction (as seen in the drawing) will suck air into the space above wall 25 and disc 27 and the opposite oscillating movement of the diaphragm will force the air through openings 30 into tube 2 from which it will be discharged into the liquid through the outlet 31.
  • a pressure or pump means for the introduction of the gaseous medium into the liquid are combined with the means for oscillating body 1.
  • gaseous medium While air has been mentioned as the gaseous medium to be used, other gaseous media can also be employed. For instance inert gases may be advantageously used when the device is employed for extracting, solving and dyeing purposes.
  • an alkali metal carbonate such as powdered sodium bicarbonate, and tartaric acid or sodium carbonate or potassium carbonate and tartaric acid.
  • an alkali metal carbonate such as powdered sodium bicarbonate
  • tartaric acid or sodium carbonate or potassium carbonate and tartaric acid are mixtures of an alkali metal carbonate, such as powdered sodium bicarbonate, and tartaric acid or sodium carbonate or potassium carbonate and tartaric acid.
  • the impurities themselves contain weak acids, as for instance, lactic acid
  • the bicarbonate or carbonate of sodium or potassium alone is sufficient.
  • the device is further provided with clamping means for removably attaching the same to an edge of a wall, particularly the upper edge of the receptacle containing the liquid.
  • clamping means are shown as comprising two jaws 12 and 13, jaw 13 being springy.
  • the upper marginal portion of the receptacle can be fitted between the two jaws, and the device is then secured by tightening a screw 11.
  • the provision of the feet and the clamping means permit either to place the device upon the bottom of the receptacle or to clamp the same to the Wall of the receptacle. It is, of course, also possible to rest the device upon the bottom and also to clamp it to the wall thereof.
  • the clamping of the device to the wall also serves to transmit oscillations or vibrations directly to the receptacle which has the advantage of increasing the effect of the oscillations of the system upon the articles to be treated.
  • the device is provided with a handle 14 extending from housing 6. This handle serves to facilitate the manipulation of the device.
  • suitable electric heating means can be mounted on a portion of the device which is submerged in the liquid during operation; for instance, one or more heater coils can be secured to frame structure 1d.
  • the heater coils are designated by 22.
