WALTER B. .BAMFORD AND HARRY W. HAMILTON, 0F DETROIT. MICHIGAN ASSIGNORS TO HAMILTON MANUFACTURING COMPANY, OF INDIANAPOLIS, INDIANA, A COB,-
ronarron orm'nmua VACUUM SYSTEM FOR INTERNAL-COMBUSTION ENGINES.
To all whom it may concern:
Be it known that we, WALTER R. BAM- FORD and HARRY-W. HAMETON, citizens of the United States, residing at Detroit, county of Wayne, State of Michigan, have invented 'a certain new and useful Improvement in Vacuum Systems for Internal-Combustion Engines,'and declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in-the art to which it pertains to make and com'panying drawings, which form a part of this specification.
Our invention relates to vacuum systems for internal combustion engines and a pmi mary object of our'improvements is to provide an improved vacuum feed system for the liquid fuel and one which shall be reliable under different conditions of operation ofv the engine; though other applications of our inventlon may be readily made.
We secure this object in the device illustrated in the accompanying drawings in which:
Figure 1 is an elevation, partly diagram matic,. vention.
- Fi 2 is a detailsectional view of a part of said apparatus.
a indicates an internal combustion engine and a' is the water jacket around the upper ends of the cylinders thereof. b is the radiator and jis a pipe connecting the water Jacket a with the interior of the radiator 6. 01s a pipe leading connecting with a pump i an apparatus embodying our md which in this case is indicated .as a centrifugal pump.
water jacket a.
e is a pipe or paage by which the water passes from the casing of the pump d to the -f is the intake passage to the engine and g indicates a carburetor connected with said intake passage. 9 represents an auxiliary reservoir placed in an elevated position and adapted to have the fuel drawn thereinto through the from a supply reservoir (notv shown vacuum, as in vacuum the exhaust pipe and i the 'mufier.
-r'is an inclosed chamber which may con,- veniently be of cylindrical form. ber 'r communicates with the vacuum'chanr her of the reservoir 9 bya' pipe q.;--
m is a pipe forming a connectlon'between- Specification of Letters Patent.
'uum in the pipe 0 and from the radiator b and Thus there are three The chain-i 1 than the others the valves 0 v.ease may be in the other passages will be Patented Oct. 30, 1917.
Application filed February 21, 1917. Serial No. 150,079. H E I the chamber 7' and the intake passage; 'mF is a cock in the pipe m for regulating the area of the passage therethrough.
n is a pipe forming a connection between the chamber 1" and thepipe 0 from which :pipe the .water is drawn by the pump 0? in producing the circulation in the cooling system. n is'a cock for regulating the area,
through the pipe 02.
'0 is a pipe connecting the chamber 1' with a portion of the exhaust passage from the engine at which a vacuum will be'drawn by the action of the passing gases, as for instance at 11 0 is a cock for regulating the area of the passage through the pipe 0.
m n and 0 are, respectively, ball valves in the pipes m n and 0 adapted to be automatically closed when. there-iris a sufficient draft toward the chamber in any one of said pipes.
The liquid fuel may be fed to the elevated reservoir 9 by the. suction of the engine acting through the pipe m, the chamber a", and
" pipe 9, as in the usual-vacuum feed system,
vacuum produced in the intake pipe of the engine. This vacuum is sometimes ineffective, as for instance, when the engine is runningwith a wide open throttle and the engine is usually at this time running at a high rate of speed.
When he engine is running at avconsiderable' speed the pump 12 actuated by the engine will be drawing a considerable vacactuated by the pipe at which will act to produce the required vacuum in the vacuum chamber of the reservoir g and elevate the fuel and this will be in most favorable operating cpnditionwhen the action from the intake pipe 1s apt to fail.
The action of the gases velocit from tile mufiier will produce a vacuum in the pipe 0 which will act to produce a vacuum in the vacuum chamber of the reservolr g and draw the fuel to said reservoir.
sources of vacuum, the intake pipe to the engine, the intake pipe leading to the circulating pump, and the exhaust passage. f any one of these sources is considerably stronger n. or m driven with great that is to say automatically closed.
through the exhaust passage and consequently in the v as the t and s are auxiliarypipes having, respectively, cocks t and s therein whlch may lead to other apparatus than the auxiliary reservoir 9 to which the pipe g'leads to produce an operating vacuumin such apparatus as, for instance, vacuum gear shiftmg apparatus, or a vacuum brake apparatus.
I have not claimed specifically herein the way of'producing the vacuum by the. action of the exhaust gases asthis forms the subject matter of an application filed by me producing passage communicating with said by said engine,
system on the suction side of said pump,
and communicating with said vacuum actuated apparatus.
3. The combination with a vacuum actuated apparatus of an internal combustion engine having an intake passage and a water circulatingsystem, a circulating pump in said water circulating system actuated a passage communicating with said circulating system on the suction side of said pump and with said vacuum actuated apparatus, and a passage communicating with said intake passage and sad vacuum actuated apparatus.
4. The combination with a vacuum actu ated apparatus, of an internal combustion engine having an intake passage and a'water circulating system, a circulating pump in said water circulating -system actuated by said engine, a passage communicating with said circulating system on the suction side of said pump and with said vacuum actuated apparatus, and a passage communicating with said lntake passage and said vacuum actuated apparatus, and automatic means whereby one of said vacuumproducing passages is closed when the effect of the other passage predominates.
5. The combination with a vacuum actuated apparatus of an internal combustion engine having an exhaust passage and a Water circulating system, a vacuum producing passage communicating with sald vacuum actuated apparatus and with said water circulating system at a point in the same where the pressure is less than atmospheric and a vacuum producing passage communicating with said exhaust passage at a point where the pressure in the same is less than atmospheric.
6. The combination of a vacuum actuated with said vacuum actuating apparatus and apparatus, an internal combustion engine having an intake passage-and an exhaust passage, a water circulating system, and a vacuum producing passage communicating with said intake passage and said vacuum actuated apparatus, a vacuum producing passage communicating with said vacuum actuated apparatus and said water circulating system at a point where the pressure in the same is less than atmospheric and a vacuum producing passage communicating with said vacuum actuated apparatus and said exhaust passage at avpoint where the pressure in the same is less than atmospheric.
In testimony whereof, we sign this specification.
