v(Cl. 26h-107) My invention relates to humidie'rs for exploi 5 Claims.

sive enginesjand hasas one of the principal objects thereof the provision of a humidifier 'so constructed land arranged as to deliver humidiiied `air toi therengine for mixture with the explosivecharges whereby to increase the efficiency of the operation of the engine and to effecten economy of raw fuel consumption, for instance, gasoline.'4

Another object of my invention is to provide a device of the abf'nvedescribedV character which is so constructed and arranged as to deliver humidied air to the intake manifold ofthe engine and tol the carburetor thereof through the medium of the Vair cleaner. y

"Another object of my invention is to provide a device of the above described character whichis simple in construction, durable in use, eflicient in operation, and economical in manufacture.

Other objects and advantages will be' app-arent froml the following description, appended claims and annexed drawings. Y l Referring tothe drawings whereinlike reference characters designate like parts throughout the several views; A

Figure '7 isa side` elevation of` the lower disk assembly in connectedu relation with the supporting standards. s l n Y In practising my invention, as illustrated in the drawing-s, I provide a cylindrical casing III constituting a humidifier container and which is pro-` vided with ran open top and a closed bottom II. One side of the casing I is formed with an offset section I2' having its lower portion in full communication with the casing as illustrated in Figure 5. The upper portion of the section l2 coacts with the upper portion of the side wall I3 of the casing to provide an opening Il in which is fixed the lower end I of a gage housing I6, the upper end I1 of said housing I6 being provided with a transparent window I8.

The lower end I 5v of the gage housing is formed with a pair of upperfand lowerjbearings in which is 'slida'bly mounted atiioat rod AI s. The lower end of the float 'rod i9 Vhasfiixed thereto a float 20, While the upper end of saijd rod is provided 'witha telltale membervZl, for uinstaura-aa colored ball, whereby thelposition of the float 2i! with respect to the casing maybe readily observed.

.Mounted vin they casing is4` Aa lpair of upright standards A2l wrapped withmo'isture absorbing material 22 constituting wicks. vThe lowervends of the standards 2| res-t upon theV bottom `Ii and have i'iXed thereto, subjacent their upper endsua lower disk assembly 23. The disk assembly 123 comprises an limp erforate disk 2l provided with an outer layer of moisture absorbing material 2'5 constituting a wick and which engages the materialV 22 4of, the standards as vclearlyillustrated Iin Figure 1 of the drawings. The disk as-sembly23 is of a suflicient `"liamet'er to Vfrictioi'ially engage the inner face ci the 'side wall- I3 'of the casing and form a seal therewith. 1 j y lReinoi'n'ibly supported on the 'upper ends o f vthe standards 2|' is an upper diskass'e'mbly 26- come pris'ihg'a'peifoated 2"l-v provided V.with vall outer layer of moisture absorbing 'materializa constituting a wick and which engages the material 22. The disk assembly 26V is of 'a'fsilicient diameter to friotionally engage the Yinner face of the upper end of the casing 'to forni a seal therewith. The `disk assemblies '723 andjzt coact with thecasing to provide `an air moisturi-ng chamber 29. The upper end of the' vcasing is closed by means of a, perforated dome-shaped and readily I removable cover 30 whereby airis admitted into the Achamber 29'. i l

Liquid, for instance'water is Vcontained in the casing, subjacent the lower disk assembly, and in which the wicks'of the standards are immersed.

- Obviously, the wicks olf the standard serve to convey the water upwardly into 'the chamber 2 9 and meisten the wicks of the disk assemblies,'where by, air drawn through 'the chamber 29 as hereinafter' described, becomes mis'tehed. Furthermore,"as illustrated infFigur'e 1, the water lloatlve# 1y supports the float, thereby enabling an observer to ascertain the Water level through the medium of the telltale as heretofore set forth.

Subjacent the lower disk assembly, the casing has extending therein, one end of a ller pipe 3| whereby water may be introduced into the oontainer. The opposite end of the filler pipe 3l, is normally closed by means of a removable closure cap 32. The side wall of the casing, adjacent the has extending therein one end of a pipe 36, the opposite end of which is connected to the intakey manifold 31 of an engine (not shown). Both of the pipes 34 and 36 are provided with cut-off valves 38 whereby moist air may be supplied to the cleaner and manifold either selectively or-simul-v taneously as desired. e

In use (it being understood that the air cleaner f is connected to the carburetor for the purpose of supplying air thereto for mixture with raw fuel, for-instance, gasoline), operation of the engine creates suction inthe pipes 34 and 36 and as a result'draws air, through the perforated top, into the air moistening chamber 29 where said air is moistenedthrough the medium of the wicks of the standards and disassemblies, and thus moistened air is supplied to the air cleaner Aand intake manifold through said pipes 34 and 36.

Without further elaboration, the foregoing will sofully explain the invention that others may, by applying current knowledge, readily adapt the same for use under various .conditions of service. Moreover, it is not indispensable that all the features of theinvention be used conjointly since they maybe employed advantageously in various combinations and sub-combinations.

It is obvious that the inventionis no-t conned to the herein described use'therefore as itV may be utilized for any purpose'to which it is adapt- Y able. It istherefore to be understood that the invention is not limited to the specific construction as illustrated. and described as the same is only illustrative of the principles of operation, which are capableV of Aextendedapplication in various forms, and that the'invention Y comprehends all construction within the scopelofthe appended claims. j v
