A Home y Patented Nov. 22, 1932 i i i rosnrn LAOH, or ENG Ewoonnnw Jnnsnrg I i LATHER GENERATNG :DEVICEV fl Application filed May 2,
The present invention relates to new and useful improvements in lather generating de-' vces. It is the primary object'of the present in vention'to equip a lather generating device with means for heating the liquid which enters' into the operation of generating lather. It is a further object of the invention to provide a lather generating device which will be in the form of a self-contained unit and which will, therefore, be readily transport able.
It is a still further object of the invention to provide a device which will generate a lather of the desired consistency in a rapid and highly efficient manner.
It is a still further ob ect to provide a device which may be readily' disassembled into its several parts for the purpose of cleaning thereof.
lVith the above and other objects in view i which will be apparent as the'nature of the invention is better understood, reference will be had to the accompanying drawing, where- Figure l is a view inside elevation of ,a lather generating clevice constructed in accordance with the present invention,
Figure 2 is a vertical sectional View of the j device, and; i
Figure 3 is a horizontal sectional view thereof. Referring more specifically to the drawing,
i the device conprisesa receptacle 5 which may be constructed from hard rubber, bakelite or other similar materiaL although other mate rials may be employed if desired. The receptacle has a neck portion 6 and this neck portion is adapted to be closed by means of a suitable stopper 7.
The reference character 8 designates a discharge nozzle for the lather, and as best'illustrated in Figure 2, this discharge spout is renovably secured in the stopper 7 by having a threaded engagement therewith.
The reference character 10 designates an immersio n heater which is preferably of the electrical type, and said immersion heater also has screw threaded engagement with the stopper 7 as designated at 11 in said Figure 2.
