UNITED STATES HARRY T. BASMUSSEN, OF DENVER, COLORADO, ASSIGNOR TO THE AUTO DEVICES AND PATENT OFFICE.
DEVELOPMENT COMPANY, O]? DENVER, COLORADO.
HEATER AND FUEL SAVER FOR AUTOMOBILES.
Application filed March 8, 1920.
To all whom it may concern:
Be it known that I, HARRY T. RASMUSSEN, a citizen'of the United States, residin at Denver, in the county of Denver and S'tate of Colorado, have invented certain new and useful Improvements in Heaters and Fuel Savers for Automobiles, of which the following is a specification.
This invention relates to attachments for internal combustion engines, and the primary object of the invention is to provide an improved means for introducing warm air into the carburetor so as to facilitate the vaporizing of the fiiehthereby resulting in a saving of the fuel and the easy starting of the engine in cold weather.
Another object of the invention is to provide an improved means for introducing the gaseous vapor in the crank case into the carburetor and for heating the said vapor, when so desired, before the entrance thereof into the carburetor.
A further object of the invention is to provide an improved attachment for internal combustion engines including a heater box having pipes for leading thereinto vapor from the crank case and warm air around or from the exhaust pipe, the box having communication with the carburetor for introducing the vapor and the warm air into the carburetor, the box also having means located therein for heating said mixture when starting the engine or the like.
A further object of the invention is to provide an improved attachment for internal combustion engines including means for withdrawing the hot gaseous vapor from the crank case of the engine and introducing the same into the carburetor for economizing the fuel and for retaining the oil in the crank case in a cool and favorable condition.
A still further object of the invention is to provide an improved means for attaching the electric heating coil in the box so that the vapor entering into the box will be thoroughly heated and broken into small particles.
A still further object of the invention is to provide an improved means carried by the box so as to facilitate the connecting thereof to difi'erent sized carburetors, thereby rendering it unnecessary to provide different sized boxes for diflerent makes of motor vehicles.
6 A still further object of the invent-ion is Serial No. 364,211.
to provide an improved attachment for motor vehicles of the above character Which is durable and efficient in use, one that is simple and easy to manufacture, and one which can be placed upon the market at a reasonable cost.
Other objects and advantages of the invention will appear in the following detailed description taken in connection with the drawings, forming a part of this specification, in which drawings:
Figure 1 is a fragmentary side elevation of an internal combustion engine showing the improved attachment applied thereto.
Figure 2 is an enlarged fragmentary detail vertical section through the oil intake pipe of the crank case, showing the means of attaching the improved device thereto.
Figure 3 is an enlarged fragmentary degill transverse section through the heater Figure 4 is a longitudinal vertical section through the same.
Figure 5 is an enlarged fragmentary front elevation of the expanding ring used for connecting the box with the carburetor connection, and
Figure 6 is a diagrammatic view of the circuit for the electric heater.
Referring to the drawings in detail, wherein similar reference characters designate corresponding parts throughout the several views, the letter A indicates an internal combustion en ine,and B, the improved fuel saving an easy starting attachment therefor.
The internal combustion engine A may be of any preferred make, and includes the cylinder block C, the crank ease D, the inlet manifold E. the exhaust pipe F and the carburetor G.
The improved attachment 13 includes the heater box H, the carburetor attaching device I. the crank case vapor conveying device K, and the hot air conveyor J.
The crank case D has communicating therewith the upstanding oil inlet filling pipe 10, to which the crank case vapor conveyor K is adapted to be attached. The upper end of this oil filling pipe 10 is enlarged as at 11 to form a vapor collecting chamber and the upper end of this chamber has detachably connected thereto the threaded cap 12. An outstanding nipple 1.3 communicates the vap r collecting chamher 11, and an overhanging lip l l is Carried by the upper end of the chamberand'extends over the nipple, so as to prevent the pouring of the oil into the nipple during the filling of the crank ease.
The improved vaporizing or heating; H includes a substantially rectangular ing having the side walls 15, the upper and lower walls 16, and 17, and the front and rear walls, 18 andl9. The rear wall 19 may be detachablyconnected to the upper and lower'walls it so desired, soas to permit repairsitothe heating coil 20 which will be hereinafter, more fully described. The rear wall is provided with inwardly extending flanges. Ql which are adapted to i rictionally engage the outer surfaces of the adjacent walls, r V
The outer or front walllS carries the cen trally disposed outwardly extending nipple QZavhich is ad apted to be engaged by the connection 23bit the carburetor G. To permit the nipple 22' t be associated with va rious sizes of carburetor connections, the nipple 22 is provide'd with an outstanding;- annular retaining flange 24 which confines an annular expansion spring" 25 in position. The ,expansion spring 25 is in the nature ofi a" cylindrical sleeve and the forward end thereof is provided with a plurality otinwardly 1 extending, tongues 26, which are adapted to engage the inner surface of the annular retaining flange 24i The spring 25 is adaptedto expandand frictionally engage theinner surfa'ce'ot the connection and it can be readily'see'n that the spring can be BXPZLIlClGdyOT contracted according; to the diameter of the connection. The removable rear wall 19. also carries the centrally disn ed m nual-div Xt nd ep nwe 27, to which is attached the rearwardly extending fleix'ible tube. 28 torining the hot air, con} veyor ll. The tube 28 oan be of any desired diameter, and is preferably of spirally wound metal inthe ordinary manner. The opposite-endof theflexible tubular member is conneotedto the exhaust pipe F or an heater connected tothe exhaust pipe F. as. the case may be. The upper Wall 16 of the heater and vaporizer boii H has formed entr y. t er n e. uv a di ie ppl 0r tubular sleeve QQ whiehjhas connected thereto. the flexible tubular member which forms a portion of the orank ease vapor conveyor outer end 1 of the v crank case vapor conveyor;lx is connectedto the nipple 13 as clearly shown in l igure got the drawings.
. Arranged transversely across the heater bo x H at the .yertieal axis thereof is; the ,hzttreoil 2Q which cqnstitutes a means for vaporizingj the.airtaken. in through the con; eyQ- i tfor t at se u th -pd formed in the crank ca'seintosmall particles The heater- QO includes a porcelain spool 32'having a spiral' groove 33 formed box . placement by Ine'ansof bolts 35 which exother suitable source of electrical energy 39.
The opposite landing post 37 is connected by wire 40 whichis grounded to the crank case. A wire ll is connectedii'o the opposite ter minal of the battery 39 and this wire is also groundedto the crank case. The wire 41 has interposed therein a suitable switch 42.
by means of which the coil can be thrown intoorout of circuit with the storage battery. p
Fromthe foregoingdescription it can be seen that an improved attachment is provided for internal combustion engine in which heated air will be supplied to the carburetor so as to effectively vaporize the fuel and thereby facilitate the easy starting o f engine and pe rmitting of a cheaper fuel being used su'ch, as kerosene and thelllkfi,
In o 'aerationbf the improved device the switchdQ is closed so as to throwthe heating coil 201 into circuit with the battery 39 and the engine is th en turnedover the ordinary Inanner. The gaseous vapors drawvn mto'the'bozr H from the cranl; case D and from the exhaust pipel will pass: around the coil 20 ow ing to the positioning thereof, which is arrangeddireetly in front of the nipples 22.}373nd 29. "lhesel gase ous yapon will then be drawn into the carburetor. After the engine" has been started becomes he'ated,, the heating coil 20 earn be thrown outlo'f cirhuit as the vapors will be heated by the engine. I i
