ff i 35% 20 he invention,- therefore, consists pri- 9 v25 carbureter an initial charge to the engine for 1,085,541. Specictfm f Letters Patent Patented J an. 27, 1914. Application led January 17, 1912. Serial No. 671,711.
To all whom t may concern Be it known that I, NAI CHOATE, a subject of the 'ng' of Siam, residing at l' ashington, in the District of Columbia, have invented certain new and useful Improvements in Starting Devices for Internal- Combustion Engines, of which the followin is a description, reference being had to the accompanying drawing and to the figures of reference marked thereon.
' he present invention relates to certain Vimprovements in ,devices for starting internal c ombustioii engines, the object being to seated valve 7, normally closed to check the admission of air from outside sources, except through the carbureter, when under the sucopening runder the suction of the engine to 55 bureter 5Y to the intake manifold. is attached' 60 combustion chamber from the engine carvalves l2 is connected to the cylinders of the 65 engine. v
At the upstroke of the pump piston, the
mixture is drawn from the carbureter the proper igniting apparatus. through the pipe 8, passing the check valve i, and at the pressure stroke of the pump 70 he mixture beingl prevented by the check,
starting purposes, said means including a bypass leading from the carbureter to the cy inder or cylnders,ywith a mechanically operated pump for forcing fuel-through the by-pass` to the cylinder or cylinders, and a check valve located in the by-pass between the pump and the carbureter.
also consists in the various matters hereinafter described and referred to in the apvpended claim. v
y invention isillust-rated in the accompanying drawings, in which,`
Figure 1 is an elevation partly in section of a multiple cylinder internal combustion lo engine having my invention applied thereshut-ofi' cock 13` is placed in the vertical portion-:of the pipe 8, so that the by-pass may be entirely closed.
The check valves l2 are shown in detail in Fig. 2. hey are attached to each engine cylinder, and allow them to receive the -mixture independently, and prevent the mixture from escaping into other cylinders whose ports are open; thus allowing the cylinder that is ready for firing to receive good compression. As herein shown, the check valve casing has iins to insure cooling while the engine is in motion. l
e Having thus described my invention, what.
claim as new and desire vto secure byLetters Patent, is
he combination with a multiple cylinder each cylinder. internal combustion engine, of an intake In'these drawings, l represents the' usual 5 multiple cylinder engine having the cylinders 2 herein shown as four in number.. Thev intake manifold is shown at 3 and the eX- manifold to each engine cylinder, a carbureter, a pipe connecting said carbureter to said manifold, a check valve in said pipe for haust manifold at 4. The carbureter 'is preventing the return of the gases through shown at 5v and has the inlet pipe 6 to the said pipefan auxiliary intake port for each i inta-ke manifold controlled bythe spring cylinder, a pipe common to each intake port, 100
dividual combustion chambers of the engine. 75
a check valve for each intake .port for 'prepump to the pipe common to the auxiliary venting the gases from escaping from the intakes. 10 cylinder, L pump, means independent of the In testimony whereof, I affix my signaengine for operating the pump, a pipe conture, in the presence of two Witnesses.
necting the carbureter with said pump, a NAI CHOATE. check valve in said pipe for preventing the Witnesses: return of the gases to the carbureter from C. L. STURTEVANT,
the pump, and means for connecting the A. M. PARKINS.
