AUXILIARY AIR DEVICE.

Application filed April 6, 1918. Serial No. 227,097.

in to the accompanying drawings.

This invention relates to auxiliary air devices and refers more particularly to a new and improved construction whereby an auxiliary amount of either hot or cold air can be supplied to the manifold of an internal combustion engine.

Among the objects ofthe invention are to provide a control mechanism or valve which in one position of adjustmentwill connect the valve cylinder to a supply of hot air and in another position of adjustment open it to a source of cold air; to provide a construction which can be economically manufactured and conveniently attached to standard constructions of automobiles; to provide means for adding a predetermined amount of moisture to the auxiliary supply of air; to utilize the auxiliary air device for priming purposes and as a lock; and'in general to provide an improved and simplified construction of the character above referred to.. Y

The inventionalso resides in the particular valve arrangement and in such further features of construction and arrangements and combinations of parts as will more fully hereinafter appear.

In the drawings:

Figure l is a diagrammatic elevational view showing a device embodying my invention installed in connection with an automobile engine;

Fig. 2 is an enlarged vertical sectional view through the control valve;

Fig. 3 is a horizontal section on the line 3-3 of Fig. 2;

Fig. 4 is an enlarged vertical section through the cold air inlet opening of the casing;

Fig. 5 is an enlarged sectional view on the line 5 5 of Fig. l.

Describing in detail the particular embodimeiit of my invention illustrated and reeV ferring first to the general construction shown in Fig. 1, A designates an internal combustion engine having an inlet manifold B receiving the explosive mixture from the Specification of Letters Patent.

sleeved within the casing F andk y with ports M,.M and M2 which control they 'Patented Jan." 4, 1921.

carbureter C; D designates the exhaust manifold through which the hot exhaust lgases are discharged through the pipe E.r

1n running internal n combustion engines, particularly those of automobiles, it is found that greater: efliciency. can beobtained byy supplying an additionaly amount ofy air` to f the carbureter mixture underL certain working conditions of the engine. yForfthis purpose I have provided an auxiliary air device comprising a valve casing F,the ports of which are controlled by a valve'G. The 01o-y erating stem G forrotating the valve is ad- ]usted by a leverH which can befextended to yany convenient positionfor operation,

preferably to a position on the dash or steering post. i, f

T he valve port J which is connected by a pipe J to `open to the kair for receiving a supply fof air at atmospheric temperatures' while a third port-L is connected by a ypipeL to casingF is kprovided with'ria y an air inlet opening under thehot-plate L2 1 which is Lfastened over the exhaust manifold L3. Each of theports are kcontrolled by the valveG'which, kas shown inFigs. 2 and 3, is formed in the shape of a cylinder provided passage 'of air into thek cylinder and also control the amount passing through the kauxiliary air device to the manifold. kThe ports M and M2 are preferably ofy a size'to yregister `with the manifold port J and the cold air port K so that a relatively large supply of cold air can be secured. Upon turning the valve to the left a quarter of a turn the port M2 will register with the hot air i of using air having an atmos-y of the engineradiator header Q, while the other end ofthe hollow wire extends be-l neath the hot-plate L2 so that when the` valve is adjusted to supply yheated air to ico ics` ythe n d the carbureter mixture it Will supply air Which contains a greater degree of moisture than usual.

In order to permit of a standard size and construction being employed With cars hav- 111g a capacity for taking a greater or lesser amount of auxiliary air supply, `there is provided in the branch connection R leading from the lhot lair port'L a cylindrical member S `having a port S which restricts the hot air opening to a greater or less degree. By ysupplying these auxiliary cylinf ders'which have 4ports of various diameters, 'it is possible lto employ one size of valve `casing for engines having .diiferent capaci ties. -lIn such case it is only necessary .for the installer to select the cylinder having struction 1K 'formed 'on its outer surface so as to receive a small amount of priming *flu-id. I also utilize the auxiliary air device as Va lock for preventing ltheft vof the CII.

As Shown 'in Fig. 4 the `valve 'G has at fits -upper v'end a flug Gwhicli is provided vWith Aan opening .G3 registering with a corresponding yopening F3 ina lug F2 on the casin- F. This Iregistration of the openings 3 and Fs'takes place When the valve 'G is adjusted to the position Where the ports M and Mr2 are in full registration with the -ports K and J, -asillust-rated in Fig. 3. It kkhas .been found in practice that when these ports are in full registration it Will be totally impossible to start the car owing to the excess amount of cold air Which is furnished to the intake manifold. By simply inserting the hasp V of the padlock V vthrough the openings Gr3 and F3 a simple and efficient locking arrangement is obtained.

Various changes, however, in the details of `construction can be made Without departing ,from the .scope of my invention.

'What I kclaim vas my invention is l. An auxiliary air device for internal combustion engines, comprising a casing having an inlet for cold air, an inlet for heated air and a connection with the intake manifold of the engine, and a cylindrical valve adapted in different positions of rotative .adjustment to connect -said cold air inlet :and `said heated air Yinlet to said vintake manifold, said valve and casing being providedL with means for lacking the valve with the cold air inlet open to the intake manifold ofthe engine.

2. An auxiliary air device for internal combustion engines, comprising a casing having an inlet for cold air and a connection with the intake manifold of the engine, a vcylindrical valve having ports adapted in one position of adjustment to connect the cold air inlet to the intake manifold,

said valve and Vcasing having coperating lugs registering when the cold air inlet is fully open, and means engaging said lugs for locking said vair inlet opening i-n its open position. V

In testimony whereof I afx mysignature.
