VAIBANIOISTENING nnvIcE.

Be it known that I, WIIMALI MEn'roN BOWEN, a subject of the King of Great Brit- Vfain, residing at N'o. 122 Thirdavenue, in

. 5; 'the city of Ottawa, in the Province of Ontario, in the Dominion of Canada, have invented certain new and useful Improvements in Air-Moistening' Devices, .of which the,

following is a specification.

The invention relates to improvements'V .in ai'1moistening devices for furnaces or the like, as described in thel present specilication and illustrated in` the accompany- `ing drawings that form part of the'same. The invention consistsessentially inthe novel arrangement and. construction of parts whereby a shallowaevaporating pan fitting within the interior` `of a furnace casing has a4 Well'secured thereto and communicating therewithand positionedyonthe outside of said casing whereby the evaporating pan ,is

; retained in position, suitable means being 'fprovided for automaticallysupplyng the ,said well with water. I

a simple and durable means for thel regular and efficient evaporation of water in furnace pans or the like, to provide a pan of In the drawings, Figure 1 is a side eleva- .tion of a .furnace with theouterfcasing partially broken away, showing the evaporating ipan and well, in section, applied theretoi Fig. 2 is a perspective view partially broken away to show the automatic means for supplyiny water to the'well. Fig. 3. is an en-V large sectional detail view of the automatic means for supplying water to the well.

Like numerals of reference indicate corresponding parts in each figure.

Referring to the drawings, 1 is a furnace of the standard hot-air type having the inner casing-2, and the outer casing 3, the heated air from said furnace passing between said inner and outer casings.

4 is a retaining ring extending around the top of the outer casing 3, and supporting the cuter dome of the furnace casing.

The outer casing 3 at the top thereof is cut away to form a substantially rectangu- Thev objects of the invention are to devise lowr the retaining rin 4. l 5 isthe pan preferily arc-sh lped to conform ,with the inner periphery bf the outer l.casing 3. The pan 5 `is quite shallow in depth, and thebottox'n r6 thereof s1ants`d0wnwardly from the inner side yto the outer side next the casing 3. I

7- is a well of much greater depth than the pan 5, and of substantially rectangular shape, said well preferably being formed integral with the pan 5, so that the top of the laropening therethrough immediately bepan, and topy of the well are of an eveneight, whereby thepan .practically forms an extension of theupper `portonof `the well. The well 7 is on Ithe outside y. ofswthe casing 3, the .openings tow y said casin `3 fitting. aroundthe outsi e1of the pan, w ere itfis connected to the well 3, so t at thejlower part of-gthe-'well projects below saidopeninfr in the casingx. The arc-shaped pan is ths suspended within the Patenten Ang. I6', 1910. 4

he to 'of casing at the'top'thercof owing to'thejveight of the well'onthexoutside of. said casing.

The bottom 8 ofthe well is also slanted toward-.the outside thereof,l and itI will be -understood that any dust orforei mat- 'ter settling in either'gthe pan ort e4 well will find its way down the slanted bottom to the outerside `of thewell at the bottom Vthereof@where the 4orifice, 9 is provided,

thi'ohgh which the dust may be cleaned, out.

10 1s a plug closin the orifice 9.

11 is an automatica -operatedvalve containedwithin the wel 7 andoperating as hereinafter fully described for supplying the well with water, which in turn will How into the evaporating pan on the interior` of the furnace casing to be evaporated by the hot air passin through the furnace.

12 is the va ve body havin the vertical cylindrical central bore 13, an the inlet 14 communicating ,throu h the arm 15 ofthe body;- 12 with the sai central bore 13.

T e arm 15 is preferabl formed inte ral with the body 12 of t e valve an is threaded on the periphery thereof where it 'extends throu h a suitable orifice in the side wall ofthe wl'7I intermediate of the height thereof.

16 are keeper `nuts threaded on the arm ,15, one to each side of the side-wall of the well and securely holding said arm, so that 12 from the central bore 13 to the top of said valve body.

19 'is a. p'intle fitting loosely Within the orifice 18 and having the ball 2O at the lower.end thereof acting as a valve and closing the lower end of the orifice 18 whenA the pintle 19 is raised in said orifice.

21 is a lever pivotally secured at one end thereof to the brackets 22 pi'ojectin upwardly from one side of the valve boy 12. The pintle 19 at the top thereof is pivotally secured to the lever 21 intermediate of its lengthby the pin 23.

24 is a fioa`t 'having a plate 25 secured to the top thereof and bridging the free end of the lever 21, a set-screw 26 being inserted throu h a suitable threaded orifice in the top o said plate againstsaid lever and retaining the float 24 at `the desired position thereon.

In the operation ofy the invention the arm 15 of the valve body is connected by suitable pip'ino' with a water supply, and the water will flow into the central bore 13, through the orifice 18, around the pintle 19, and then 'find its way out of the top of the valve into the well until the well is filled, and also the evap'orating pan to a suflicientheight.

The water as it rises in the well will buoy surface of the water in the pan and the well struction of the evaporatin has been lowered sufficient by evaporation to lower the float, which presses downwardly on the pintle 19 and lowers the ball valve 20 from its seat at the lower end of the orifice 18.

This is a very simple arrangement of valve, and will -operate very satisfactoril It must be understood, however, that I o not wish to be confined tothe exact conpan and well herein shown and describe as it may be necessary 4with different types or shapes-of furnaces to alter the shape of the'pan. It may The essential features of the invention will be found in the peculiar shape of thc pan, whereby it can readily be supported through an opening in the outer casing of the furnace at any convenient place, as the pan does not 'require any means of support .other than the side wall of the casing itself.

of shallow depth fitting the interior contour' of said casing and having a Well section formed integral therewith and protruding through the opening in said casing and su porting said arc-shaped shallow pan on th) interior thereof, a valve contained within said well and connected to a suitable water supply and a float operatively connected to said valve for supplying water to saidypan.

2. The combination with the outer casing of a hot-air furnace or the like having an openin therethrough, of an arc-shaped pan of sha1 ow depth fitting the interior contour of said casing and having the bottom thereof slanting toward saidcasing, a well section formed integral therewith and protruding through the opening in said casing and supporting said arc-sha ed shallow pan on the interior thereof an having a threaded orifice through the bottom thereof, a plug 4fitting said orifice, a valve contained within said well and connected vto a suitable water supply and a float operatively connected to said valve for supplyin water to said pan.
