AIR-TREATING DEVICE.

Application filed January 4, 1923. Serial No. 610,725.

T 0 all whom it may concern Be it known that I, GUSTAVE ADoLr KEL- man, a citizen of the Republic of Germany, residing at Cushing, in the county of Payne and State of Oklahoma, have invented certain new and useful Improvements in Air- Treating Devices, of which the following is a specification reference being had to the accompanying drawings.

This invention relates to air treating devices for internal combustion engines, and more particularly to a device for treating the air which is admitted to the carbureter thereof. I

An important object of the invention is to provide a device of this character which simultaneously feeds to the carbureter moistened air and oil laden air.

A further object of the invention is to provide a device of this character wherein the feeding of moistened air is discontinued during those times at which the engine is traveling at low speeds, it having been found that the feeding of moistened air in large quantities to the engine when the same is traveling at low speeds and not highly heated results in a collection of this moisture upon the valves and valve stems with the result that the same become rusty and stick.

A still further object of the invention is to provide a novel and improved means for moistening air for use in an internal combustion engine and for straining from the air any particles of dust or-dirt which might be contained therein.

Another object of the invention is to provide a device of this character which may be readily applied to engines of various con structions without materially altering the construction thereof.

An additional object of the invention is to provide a device of this character which is durable and efficient in service and which may be cheaply produced.

These and other objects I attain by the construction and arrangement shown in the accompanying drawings wherein for the purpose of illustrationis shown a preferred embodiment of my invention and wherein like reference characters designate like parts throughout.

In the drawings Figure 1 is a side elevation of an internal combustion engine showing apparatus constructed in accordance with my invention applied thereto; 7

Figure 2 is a vertical sectional View through the air moistening device;

Figure 3 is a section on the line 33 of Figure 2; and

Figure 4 is a detail sectional view through the connecting conduit.

Referring now more particularly to the drawings, the numeral 10 indicates a casing substantially rectangular in cross section and provided with means, as at 11, whereby it may be secured to the dashboard D of a motor-vehicle or to any other suitable support. The casing 10 is provided with a curved upper wall 12 and has extendingupwardly from the lower wall thereof approximately centrally of such lower wall a dividing wall 13, the upper end of which is in spaced relation to the curved upper wall 12 forming within the casing a passage 14 having its ends disposed at the bottom of the casing. The bottom wall of the casing has formed therein at one side of the dividing wall 13 an air inlet opening 15 which is covered by a screen 16 to prevent the entrance of large particles of dirt, and at the opposite side of the dividing-wall 13 with an outlet opening 17 communicating with a flexible conduit 18.

The numeral 19 designates a water casing which is in communication through its valved inlet 20 with a conduit 21 leading to and communicating with the water jacket W of the engine. This casing is provided along its upper end with .a restricted outlet 22 in communication throughout its length with the lower end of the casing 10. Ar ranged within the casing 10 are a pair of shields or strainer members 23 and 24, these shields extending transversely entirely across the width of the casing 10 and being of different lengths. The lower edges of the shields are arranged against the restricted opening 22 of the casing 19 for a purpose presently to appear. and have their upper edges resting against and preferably se cured to the dividing wall 13 of the casing 10. Being of different lengths. the upper ends of these strainermembers are maintained in spaced relation and the strainer members being fiat. aare maintained in .spaced relation except at the lower ends thereof. The strainer members 23 and 2 1 have applied thereto a coating. of fabric 25, the lower; end of which enters the restricted miliar 'biir'eter V r p and destrnctlon of the cylinder walls and departi. and I outlet of the casing 19 and thecasing 19 is provided with a filling of some material such as absorbent cotton, as indicated at 26. Upon water beingadmitted to the casing 19, it will be fed along the fabric strips by capillary attraction and moisture will be added to air entering at the inlet 15 and passing through the screens 23 and 24: by contact.

The numeral 27 designates a conduit adapted at one end, as 21132855301 engagement with the air inlet pipe 29 or: the carbureter C, and-at its opposite end with winner adapted for engagement with the free end of the conduit 18. Adjacent the inlet 30 and within the conduit is arranged a screen 31, and the adjacent end of the air inlet is formed to provide a seat for alball valve 32 normally held iii-engagement with such seat by means ofa spring 33. Intermediate ,tlieiscreenfil and the outlet "28, the conduit 27 is provided witlra second inlet Zilwhich is adapted for connection by-a tle'xible conduit and, a suitable fitting '36 with a 'bre'atheroutlet B of the enginebase.

As will beseen from. an inspection of the drawings, the moistened air inlet 30 for the conduit 271's of less size than the air inlet 34 by means of which the conduit is connected with the engine base. Accordinglyat all times during'operation "oi": the engine at high speed when a considerable amount o'ffair is being drawn through the inlet of the carburetergalla ainount 'ot air will be drawn from the crankcase and a smaller amount from the casing 10,,th e air from the crankcase being laden with,gasoline and oil fumes and that from the cas .ing 10 being moistened. When the speed of the engine is lessened to 'apoint when suflicient, aircan be withdrawn, from ,the crank case without creating therein. too tire-at a vacuum, the valve closes and ,allof the air entering the carbureter is drawn from the case. It is pointed out that since all oil? the air entering theengine at any time is either drawn from a point atwhicli there can be no dust or drawn through a device which will. remove therefrom the dust, the collection er such dust uponj the interior of the engine is prevented. Tothose tawith theert, it is well known that jering the cylindf through the caris 4 one of the iii'aijor causes ofscoring pistons. 4, v
