GOMBINED'WATER HEATER A1331 STEBILZZING ASPPARATUS.

Application filed December 8, 1924. Serial No. 754,818.

This invention relates 'to a combined water heater and sterilizing apparatus adapted to be used more particularly by barbers, dentists, and other users requiring frequent supplies of relatively small quantities of hot water and steam for shaving, laving, moisteningand sterilizing purposes.

The main object is to provide a compact and easily portable container with intercommunicating chambers, one of which is adapted to receive the-water to be heated and contains an electrically heated element for imparting the necessary heat to the water therein while the other contains means for supporting articles to be moistened or sterilized by the heated water or steam from the receiving chamber.

Another object is to provide the sterilizing chamber with a perforated plate or tray, adapted to receive and support the articles sterilized above the normal level of the water which may be transferred to the sterilizing chamber from the water adhering to or thus permitting the excess held in saturation by, said articles to drain into the underlying portion of the sterilizing chamber.

Other objects and uses relating to the specific parts of the apparatus Will be brought out in the following description. In the .drawings:'

. Figure'l is a vertical sectional view of an apparatus embodying the features of my invention. j

As illustrated, this apparatus comprises an uprightcontainer 1', consisting of ,cylindrical shells, 2 ant 3, one of which as isof relatively large diau'reter to form what maybetermed a sterilizing chamber L, the. other chamber -2-' beheating chamber,

' ing of greater vertical length than the shell to extend some distance below and 'above the bottom and top' thereof and forms what may be; termed .a water receiving cham- The shell 3-v is provided in one side with a lengthwise recess 16 of substantially'circular cross section corresponding to the diameter ofthe shell 2 which it is barbers, dentists or others who may find use In other ords the portion of the shell 2- which is embraced by the adjacent portion of the shell 3- constitutes a partition wall 7 which is perforated to establish intercommunicating passages between the chambers land 5- and between the bottom wall as S and the top wall as 9 of the chamber 8-.

The bottom 2 of the shell -2 is provided with an inlet -10 adaptedto be connected by a pipe -l1- to any available source of water supply from-Which water may be fed into the chamber 5 where it is adapted to be heated in a manner presently described.

The upper end or top -12 of the shell -2- is secured in place by screws -13 and serves as a part of the support for an electric heater 14;.

This heater is similar to that set forth in my pending application Serial Number 751,065, filed November 20, 1924 and is also suspended from the top 12 in a similar manner to be partly or completely immersed in the water in the chamber 5.-

Electric current may be supplied to the heater 1 l from any available source and inay be controlled by the temperature of the water in the chamber '5 through the medium of an electric switch l5 and a thermostatic bar l6 constructed and arranged in a manner similar to that set forth in my pending application above referred to except that the outer jacket for the shell 2 is omitted.

The bottom -8- of the sterilizing chamber l is disposed in a horizontal plane some distance above the bottom 9-" and also some distance below the top ,12- of the shell -2- and is provided with an outlet pipe 17 leading to afaucet 18 from which the hot watermay be drawn in small quantities as needed.

As previously explained the partition 7* between the chambers l and -5 is perforated as indicated at -19 to allow the hot water and steam to pass from the chamber -5% into the sterilizing chamber L to be used formoistening towels and similar articles used by barbers and also for sterilizing tools and similar object used by for a device of this character.

The perforations l9 extend from the bottom -8- to the top 9- of the sterilizing chamber and therefore the water in the chamber which is heated by the heater -14 is allowed to pass into the chamber :l: as soon as it reaches the level of the upper surface of the bottom 8.

A baflie plate 20 is secured to the partition 7 above the lowermost perforations 19- and extends therefrom into the chamber 4- in spaced relation to the bottom 8 and is preferably circular in plan but of considerably less diameter than the interior diameter ofthe chamber 4 to form passages for the stem between its marginal edge and walls of the shell.3.

A perforated plate 2l having legs .22- is loosely supported in a horizontal plane upon the bottom 8- of the chamber 4tso as to underlie the baffle plate 20 in vertically spaced relation thereto. I

This perforated plate 21 is also circular and of substantially the same crosssectional area as the interior of the chamber 4 except as to a slight clearance around the marginal edges thereof to permit it to be removed through the top of theshell 3-- when the cover -9is opened.

The water level in the chamber l indicated by the dotted line is maintained just below the bafiie plate 20 by any suitable means not necessary to herein illustrate ordescribe while the baffle serves to prevent the direct upward passage of the steam resulting from the heating of the water in the chamber 4- and allows such steam to pass upwardly around the marginal edges of the baffle plate and thence throughthe perforations as Q1 of the plate 2l for moistening or sterilizing anyarticles which may be placed upon said late.

p The bottom 8 of the chamber is provided with heat-insulating material 8 to prevent sudden cooling of the hot water which may pass from the heatingchamber into the chamber 41 and also reduces the liability of condensation ofthe steam which may be generated as a result of the heating of the water.

The top -9 of the sterilizing chamber &- is hinged at 9 to permit it to be swung upwardly and laterally for opening the top of the chamber and permitting articles to be placed through the opening upon the perforated tray 21 preparatory to moistening orsterilizing after the lid 9 has been returned to its closed position.

Operation.

according to the adjustment of the thermostatic bar +16- and when it exceeds that degree the bar l6 will be deflected by the heat imparted thereto to engage and operate the movable switch as for breaking the circuit through the heater, the degree of temperature being maintained antomatically by the operation of the thermostatic bar -16 it being understood member 15- is self-closing when released by the withdrawal of the thermostatic bar l 6 therefrom as for example when the temperature of the water in the chamber 5 drops below the predetermined degree mentioned.

Under these conditions hot water escapes through the perforations l9- below the baffle plate -20 and into the chamber 4;- across and upon the bottom -8 while the steam rises'around the marginal edges of the baflie plate and escapes upwardly through the perforations in the plate -2l.

It, therefore, follows that any towels tools, or other articles which may be placed upon the tray 2lwill be subjected to moisture or sterilization 'or to both moisture and sterilization by the steam escaping upwardly through the perforations in the plate 21 and that moistening and sterilizing may be continued indefinitely for the same articles or repeated with otherarticles as may be'desired.

In other words the maintenance of the hot water and "steam atthe desired temperature within the chamber l renders the apparatus available at all times for moistening and sterilizing purposes. v

011 the other hand if relatively small quantities'of water for shaving and other purposes are required it is simply necessary to open the faucet'l8andto discharge the water therefrom into any receptacle provided forthat purpose.

WVhat I claim is: I l. A combined water heater and sterilizing apparatus comprising an upright'cylindrical water heating chamber having a water inlet at its lower end and its upper end closed, a heater supported from the closed upper end of the heating chamber above the water inlet and a sterilizing chamber embracing a portion of one side of'the heating chamber above the lower end of the heater, the portion of the heating chamber embraced by thesterilizing chamber being perforatedto permit the passage of steam fronrthe heating chamber to the sterilizing chamber.

2. A combined water heaterand sterilizing'apparatus comprising an upright cylindrical water heating chamber having a water inlet at its lower end and its'upper end closed, a heater supported from the closed upper end of the heating chamber above the water inlet, a sterilizing chamber embracing a 7 portion of one side of the heating chamber above the lower end of the heater, the

embraced by the sterilizing portion of the heating chamber chamber being provided with a seriesro-f perforations arranged one above the other for intercommunication above the lowermost perforations.

between said chambers, and a perforated plate loosely mounted in the sterilizing chamber in a horizontal plane above the water inlet, a sterilizing chamber embracing a portion of one side of the heating chamber above the lower end of the heater, the portion of the heating chamber embraced by the sterilizing chamber being provided with a series of perforations arranged one above the other for intercommunicat-ion between said chambers, a perforated plate loosely mounted in the sterilizing chamber in a horizontal plane above the lowermost perforations, and a horizontal baffle plate extending laterally from the perforated side of the heating chamber between the perforated plate and bottom of the sterilizing chamber and of less area than the interior of the sterilizing chamber toallow the upward passage of the water and steam around one edge thereof.

In witness whereof I have hereunto set my hand this 24th day of Nov., 1924.

ALPHONSE MARTIN.
