THOMAS B. DOOLITTLE, OF BRANFORD, CONNECTICUT, ASSIGNCR TO HARRY W. DOOLITTLE, TRUSTEE, OF NEW HAVEN, CONNECTICUT.
CQNTROLLING THE EXHAUST FROM INTERNAL-COMBUSTION ENGINES.
To all whom it may concern:
Be it known that I, THOMAS B. DooLrr'rLn, a citizen of the United States, and resident of Branford, in the county of New Haven and State of Connecticut, have in-- vented a new and useful Tmprovement in Controlling the Exhaust from Internal- Combustion Engines, of which the following is a specification.
My invention relates to means for handling the exhaust from internal-combustion or explosive engines used in marine propulsion and it has for its object to overcome the noise of such exhaust without interpos ing any obstacle to its free discharge.
In carrying out my invention I cause the products of explosion discharged from the cylinder and preferably also the water discharge from the cylinder jacket to enter a chamberor chambers communicatingwith the sea or otherbody of water in which the vessel is borne. The water in the chamber having free communication with the water outside is of the same temperature, which is therefore much lower than that of the water and gas discharged therein, and in this way it acts to reduce the temperature of the ex haust to a point at which it may be discharged freely without undue expansion and consequently without noise.
In the drawings which accompany and form a part of this application, the figure is a diagrammatic view showing one embodiment of my invention.
In the drawings, A represents the cylinder of an explosive engine and B the discharge of the water which has been pumped through the water jacket I.
C represents a chamber communicating with the outside water as shown at F, and hence containing a body of water D at sea level. Into this chamber also as shown at E is introduced the exhaust from the cylinder A. A pipe G, preferably carried through the side of the vessel above the water line, permits free escape from the chamber C. The outer end of the pipe F may be so formed as to cause the water of flotation to be forced into the chamber 0 by means of the forward motion of the vessel, and thus more rapidly cool the contents of the chamber C. A lip or projection f upon the pipe F may be used for this purpose.
I Specification of Letters Patent.
Application filed August 27, 1908.
Patented May 18, 1909.
Serial No. 450,459.
It will be observed that in the apparatus herein shown and described. there is no battle or other obstacle to the discharge and hence there can be no possibility of objectionable back pressure in the cylinder. On the other hand experience has shown that th discharge is wholly or substantially noiseless.
The discharge from the cylinder jacket need not necessarily be led into the chamher C, but may be independenly disposed of, but its being carried into said chamber is believed to be both convenient and beneficial.
It is obviously desirable to have the exhaust passage from the engine enter the water chamber C at a point above the water level thereof to avoid back pressure. It is also convenient, although not so essential, to have the passage from the water jacket to the engine enter tlxe chamber C above its water level.
I claim:
1. In a device for preventing noisy exhaust of marine explosion engines, in combination, a water-containing chamber, a passage for supplying said chamber from the water of flotation, an exhaust passage from the engine entering said chamber, and an exhaust delivery passage independent of the water supply passage and leading from the watercontaining chamber above its water level.
2. In a device for preventing noisy exhaust of marine explosion engines, in combination, a water-containing chamber, a passage for supplying said chamber from the water of flotation, an exhaust passage from the engine entering said chamber, a dis charge passage from the water-jacket of the engine communicating with the water-containing chamber, and an exhaust delivery passage independent of the water supply passage and leading from the water-containing chamber above its water level.
In testimony whereof, I have hereunto subscribed my name this 5th day of August, 1908.
