r This invention relates toattachmentsfor internal combustion engines, the object. of

the invention beingto provide novel means is to provide means for heating the air after it has been treated, and prior to its passage to the carburetor to increase the efficiency of the engine. V

A still further object of the invention is ,toprovide a device of this character which may be readily and easily applied to motor vehicle construction, eliminating the-necessity of making alterations in the construction to install the device. v With'the foregoing and other objects in view which will 'appear as the' description proceeds, the invention resides in the combination and arrangement of parts and in the 1. details of constructionhereinafter described and claimed, it being understood that changes in the precise embodiment of'the invention herein disclosed, may-be made within the scope ofwhat is claimed, without departing I 80 from the spirit .of the invention. 1 9

' Referringto the drawings in detail, the:ref-.

erencecharacter 5 indicates an internal combustion enginewhich is supplied with a shaft 6 on which the pulleys 7 and 8 are mounted,

the] pulley 8 transmitting;movement to the pulley 9, 1gou nted on the shaft'7, through the belt 1 .1

. Pulley *6 transmits movement ,to the pulley 7Y through the medium of a belt that operates thereover. The pulley 16 ismounted on the fan shaft'fi and receives motion there- Mounted on theshaft-7 "is a blower 8 operating in the housing '9. which is formed withselongated openingslO for theirecep' .The blower8 operateson the ball bearings- 11 that surround the bearingmember 12 that in turn isformed on the shaft 7 as clearly shown by Figure ,2 ofthe drawings so that the fan will; operate freely;

' Openings 13are formed in one wall-'ofthe blower housing so that astheblower 8 is rotated' within the housing, air will be drawn through-the'opening; where'it is passed through the outlet opening 14 of the housing,

pipe'15' formed which communicates with the integral .withthehousing. A

Th device also includes awater tank that communicates with the pipe 15 through.

the-pipe 17' in such a way that air. will be blown througlrthe pipes 15 and 17 i and -.di-

rected to=the interior of the tank "161' l Pivotally' 'mounted. adjacent to the lower end of the pipe l8 which is in communication with th Pipe 17 is a pipe 19-.whichhas a dowrn wardly extended end portion adapted to lie under the level of the water in the tank- 16 so that in order for air to pass from the employed for securing thetank 16 to the'en gine construction. V v

The reference character 23 indicates the outlet pipe for the tank 16, which pipe communicates with the valve casing 24 to supply filtered air thereto. The valve operating within the casing24, compriseslateral disks the pipe 27.

25 and 26 respectively, the disk 25 being provided with circular openings 27 that establish communication between the interior of the valve casing and

pipes

39 and 44 respectively, which pipes extend through openings in the rear side of the valve casing. A'pipe 47 also extends into the valve casingat'the-front side thereof and provides direct communication between the casing and carburetor of the engine with which the device is used."

The disk 26 is'supplied with a single opening which-may be brought into registry with These disks 25 and 26 are I iounted on the shaft 30 to move therewith, and are held in spaced relation witheach other by means of the coiled spring 31 which also acts to hold thedisks into closeengagementwith the inner surfaces of the walls of the casing. The pipe 39' connects with the heating chamber '40 that. surrounds V the exhaust pipe 41 of the engine in spaced relation therewith so that air passing through i the pipe 39 will be heated as it passes into the heating chamber 40. V A pipe 42 connects with the heating chamber adjacent to the upper end thereof, and connects with the union 46 thatin turn is supported on the heating chamber 45 mounted on the exhaust manifold 45 oftheengine to the end that air which has been heated,'and which passes through the pipe '42 may be further heated by its passage through'the heating chamber 45., Pipe 44 establishes communication between the valve casing 24 and union '46. The referencecharacter 46, designa'tesa pipe thatleads-from the heating chamber 45 to thecarburetor not shown, so that the air passing through the heating jchamber45 may bedirected tothe carburetor. 1 y I p p The controllinglrod is indicated-by the reference character 34 and connects with-the shaft 30'at one end of the rod, the opposite 1 end of-"the rod extending to a position in proximity to the operators seat where itis provided with a handle 35 carrying a lockin pin 36 adapted to move into the openings 3 formed in the disk 38 that constitutes a part of, the support for the operating rod 34.

l/Vater is supplied to the tank 16 through the filling pipe 50 which is supplied with a cap 51 to close the outer end thereof. At the bottom of the tank is a discharge pipe 52 which is normally closed by the. cap 53 so that should it be desired to drain. the tank and remove the sediment therein,.this may be-accomplished byremoving the cap 53.

The operation-lofthe devices is as follows:

During summer running the valves are moved so that the opening in disk 26 will register with pipe 47 it being understood that the disk 25 is so arranged with respect to the disk 26, that when, the disk 26 is; in a'posiing to-the carburetor, the rod 34 may be op-.

erated to cause'one of the openingsof the disk 25 to register with the pipe 44, the pipe 47 being closed by the disk 26; Thus it will be seen that air may now pass through the pipe 34 in the direction of the arrow A,

' through the heating chamber 45 and through pipe 46 wherethe heated air is delivered to the carburetor which is connected with. the pipe 46.- F g Inmoderately cold weathenthe rod'34 may be operated to cause the'ropenings 27 of the disk 25 to register with the

pipes

39 and 44 whereupon the air passing throughthe valve casing, will passthrough pipes 39 and 44tsimultaneou'sly, a portion of the air pass; ing throughthe heating chamber 40, through pipe 42from where it passes through the union'46 and into the heating'chamber 45'.

K In extremely cold weather therod 34n1ay be operated to cause the openings ofthe disks 25 and 26-that register with the pipes 44and 47 respectively,to be closed,- one of the open ings to the disk, 25 being in registry with the pipe 39;to theend that the air will .take'the direction of travel as shown by arrows B in Figure 1 of the drawings, whereupon the air will be heated by its passage through the heatingchamber-40, pipe 42, union 46aTnd heating chamber-4 5;

Icla'im: 1. ,In combination with the carburetor and exhaust pipe and manifold. of-an internal combustion engine, an air filtering and mixing device comprising qa water'tank', means for forcing air throughthe water in tliewater tank, a valve casing associated with-the tank and in communicationtherewith, a pipeleading from the valve casingtothe carburetor,'a heating chamber mounted on the exhaust pipe, a heating chamber mounted on the' ex.-

haust manifold, a'pipe for 'establishing'communication between the valve casing and heating chamber mounted on the exhaust pipe, a pipe establishing communication; between the heating chambers, a pipe establish- I ing communication between the valve casing and heating chamber mounted on the exhaust manifold, a valve in the valvecasing for con- 1 trolling the passage of air to the heating chambers, and a pipe establishing communication between the heating chamber mount- 10 ed on the exhaustmanifold and carburetor.

2. In combination with the carburetor and exhaust manifold of an internal combustion engine, an air mixing and filtering device comprising a water tank, 'means for forcing air through the water in the tank, a drumlike valve casing, a pipe establishing communication between the tank and valve casing, heating chambers, pipes for establishing communication between one side of the valve casing and heating chambers, a pipe establishing communication between the valve casing and carburetor, disks having openings, positioned within the valve casing, and means for operating the disks to bring the openings of one:

' diskinto registry with th'epipes leading to I the heating chambers .and simultaneously cut off communication between the casing and pipe leading to the carburetor.
