Definitions

  • the present invention relates to means for agitating liquids and has for an object to provide an improved portable agitator for liquids which is inexpensive, easily positioned, 'and adapted for use with various kinds of liquid containers.
  • Removable agitators for domestic washing machines are known but such agitators are adapted for use in a specically designed tank or receptacle usually having an upstanding column or the like in which the agitator seats.
  • the column is usually positioned centrally of the tank although in one known construction the column is located outside the tank and connected there to by suitable pipes'or ducts.
  • .means are usually provided for maintaining the articles immersed in the liquid contained in the tank free from the inlet and/or outlet of the agitator, which means are incorporated in the tank constructionproper and do not form' part of the removable agitator.
  • Portable agitators are also known which are adapted for use in any suitable container but such agitators are not shielded from contact with articles which may be immersed in the liquid in the container and consequently the liquid immediately surrounding the agitator is not maintained free fromrobstruction by 'such articles.
  • the liquid is agitated either by means of .a continuously rotating paddle or other form of 'blade which is submerged in the liquid, or the liquid is agitated by means of a 'paddle which is adapted to be reciprocated and which is positioned to lie just below the level of the liquid.

  • the shaft 3 has mounted on the upper end thereof a crank to which is connected one end of an arcuate link member 6 by means of a crank pin 1.
  • the other end of the link member 6 is connected to a crank 8 by means of a crank-pin 9 the crank 8 being mounted on the lower end of a vertical spindle I9 having a gear wheelfll in engagement with a wormllZ mcuntedon one end of the motor shaft i3.
  • Rotation of the motor shaft is translated through the link and crank mechanism into an oscillating movement of the shaft 3 about its longitudinal axis whereby the blade 4"is'caused to move to and fro between theextreme positions shown in Figure 3.
  • a downwardly depending cage l5 conforming to the contour of the base plate and extending a short distance below the lower edge of the blade 4.
  • the case I5 is constructed of wires or rods I6 forming ascreen the meshes of which are sufliciently large to enable easy ow of liquid to'and from the agitator blade but serve to keep large solids such asfarticles of clothing for eX- ample clear of Ysaid blade.
  • the wall of the cage is strengthened by a plate Il extending the length thereof and forming that portion of the wall lying to the rear of the shaft 3.
  • a detachable cover 2l is adapted to fit on the base plate and encloses the motor' 2 and the link mechanism.
  • a suitable aperture 22 is provided in the cover through. which passes a flexible connection 23 for connecting the electric 1 motor to any suitables'ource of electric power.
  • the blade type liquid Vagitator of Figure 1 has been replaced byan uplift tubetype of agitator.l
  • the motor 2 is mounted vertically upon the baseV plate/I which supports an uplift tube 2.5 extending downwardly within the cage l5.
