STARTING ATTACHMENT FOR INTERNAL-COMBUSTION ENGINES.
Specification of Letters Patent.
Patented Feb. 23, 1915.
Application filed March 26, 1914. Serial No. 827,293.
To all whom it may concern Be it known that I, BENJAMIN A. PownLL, a citizen of the United States, residing at Forest Home, in the county of Antrim and State of Michigan, have invented certain new and useful Improvements in Starting Attachments for Internal-Combustion Engines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention relates to new and useful improvements in internal combustion engines and more particularly to an attachment therefor which will enable expeditious starting of an engine in cold weather.
An important object of my invention is to provide an attachment whereby the proper mixture of combustible gases is provided and the engine may be readily started.
In internal combustion engines particularly the horizontal kerosene type in some instances the fuel tank is disposed below the level of the carbureter thus in starting the engine the suction produced by the hand turning of the fly wheel is not sufficient to provide the proper mixture and a great deal of trouble is experienced particularly in cold weather in starting engines of the type mentioned.
My invention relates to an attachment whereby the above mentioned engine may be readily and easily started and consists of means for producing suiiicient suction upon the hand turning of the fly wheel to provide the proper mixture for the cylinder.
Another important object of my invention is to provide an attachment of the character described which is simple as to construction capable of being readily attached and detached and cheap to manufacture.
The above and additional objects are ac complished by such means as are illustrated in the accompanying drawings, described in the following specification and then more particularly pointed out as claimed.
With reference to the drawings, wherein I have illustrated the preferred embodiment of my invention as it is reduced to practice, and throughout the several views of which similar reference numerals designate corresponding parts; Figure 1 is a side elevation showing a gasolene tank, carbureter, an air intake pipe and cooperating parts of an internal combustion engine, and Fig. 2 is a front elevation of the gasolene tank, carbureter, muffler of an internal combustion engine also showing the cylinder in dotted lines and the hot air pipe for the carbureterin operative position, also my attachment in the hot air pipe and on the air intake pipe for the carbureter.
Referring to the drawings by characters of reference the numeral 1 designates a fuel tank that is operatively connected with a carbureter 2 by means of a pipe 3.
The carbureter 2 is provided with an upstanding pipe 4: extending from the mixing chamber of the carbureter and supplying air thereto. An upstanding pipe 5 is carried upon and in communication with the carbureter 2 and is connected at its upper end by a coupling 6 with a hot air intake pipe 7 that extends laterally or horizontally with respect to the pipe 5. The coupling 6 is T-shaped and at the upper end of the T-portion is provided with a priming cup 8. The hot air intake pipe 7 is provided with a downwardly turned and open end 9 that is disposed adjacent to the exhaust manifold 10. The exhaust manifold 10 carries the usual muflier 11 at its upper end and is connected with the cylinder of the engine 12 shown in dotted lines in Fig. 2. The downwardly turned open end 9 of the hot air intake pipe 7 is disposed in such a way that heated air will be drawn into the carbureter since the portion 9 is disposed immediately adjacent to the exhaust manifold 10.
My attachment comprises a valve 13 that is positioned within and intermediate the ends of the pipe 7, and a flanged internally screw threaded cap 14: that is mounted upon the upper end of the cold air intake pipe 4. The valve 13 serves to cut off the air supply from the pipe 7 to the carbureter 2 while the cap 14 cuts off the air supply to the carbureter 2 from the pipe 3. When it is desired to start the engine the cap 14 is turned upon the upper end of the pipe 4:, said pipe 4 being screw threaded for this purpose. The pipe 4 is then sealed and no air can get to the carbureter therethrough. The valve 13 is closed so that the air is prevented access to the carbureter 2 through the hot air pipe 7. When the fly wheel of the engine not shown is turned air is drawn into the carbureter through the priming cup 8 and pipe 5. The air in being drawn through the small passage from the priming cup to the carbureter 2 causes the fuel to be drawn or sucked rapidly into the carbureter 2 and the proper mixture is provided to start the engine. The air passes rapidly through the priming cup 8 and pipe 5 to the carbureter 2 and in so doing causes a great suction. The suction produced causes the fuel to be sucked readily into the carbureter and with the air that is drawn by the suction of the piston in the engine cylinder through the priming cup 8 t0 the carbureter 2, causes the proper vaporization of the fuel and the engine will be readily started. Without my attachment the engine described when turned by hand, particularly in cold weather does not produce sufficient suction to cause the proper amount of fuel to be sucked to the carbureter 2 and as a result the proper mixture is not had. It will be readily seen with my attachment, that the proper vaporization of the fuel is had and engines readily started. After the engine has been started the cap 14 is unscrewed and the valve 13 opened and the engine is permitted to run in the usual manner.
It will be readily seen with reference to the foregoing description and accompanying drawings that I have provided a simple and inexpensive attachment which will enable an expeditious starting of internal combustion engines in climates wherein proper vaporization is not readily had.
In practice, I have found that the form of my invention illustrated in the drawings and referred to in the above description, as the preferred embodiment, is the most efficient and practical; yet realizing that the conditions concurrent with the adoption of my device will necessarily vary, I desire to emphasize the fact that various minor changes in details of construction, propor tion and arrangement of parts may be re sorted to, when required, without sacrificing any of the advantages of my invention, as set forth.
What is claimed is 1. The combination with a carbureter having a cold air and hot air intake pipes and a priming cup operatively connected and communicating with said hot air pipe of a valve arranged within and intermediate the ends of said air pipe and a cap to seal said cold air intake pipe removably fitted thereon.
2. In a starting attachment for internal combustion engines, the combination with a fuel tank, a carbureter operatively connected with said fuel tank, an exhaust manifold, a hot air intake pipe operatively connected with said carbureter and disposed adjacent said exhaust manifold, a cold air intake pipe for said carbureter and a priming cup operatively connected with said carbureter of means for closing said cold air intake pipe and said hot air intake pipe to prevent air being drawn into the carbureter through the hot air and cold air intake pipes and permit air to be drawn into said carbureter through said priming cup.
3. In a starting attachment for internal combustion engines, the combination with an engine comprising a cylinder, an exhaust pipe for said cylinder, a fuel tank, a car bureter operatively connected with the fuel tank, hot and cold air intake pipes for said earbureter, a priming cup operatively connected with said hot air intake pipe of a valve mounted within and intermediate the ends of said hot air ipe, said cold air intake pipe being threaded at its outer end and a flanged internally screw threaded cap removably mounted upon the threaded end of said cold air intake pipe to seal said pipe.
In testimony whereof I aflix my signature in presence of two witnesses.
