To c?! 'wlw-m t may concern: A
Be it known that I, Enwsnn RATHBUN, a
which the following is a specii'ication.
lviy invention relates to engines and other engines requiring cooling et their cylinders, and comprises head jackets and cylinder jackets c/onnected to receive the cooling iuid. successively, as hereinafter described. l l
In the water cooling of the cylinders ot' large gas engines and the like, having both cylinder jackets and head jackets, (which are usually directly connected), considerable diiiculty is experienced from too high telnperature of the Water in the head jacket. While the cylinder head is thejhottest part the connections of the head jacket and cylinder jacket are usually such that the head jacket receives the cooling Water after it has been hea-ted to a consider! able degree in the cylinder jacket; so that the water is hottest at the point where it should, be coldest. As a result, the cylinder head is maintained at a higher temperature than is desirable, and steam may be liberated in the head jacket and pocketed there. j
According to my invention, the head jacket and the cylinder jacket are separate, and receive the cooling water'successively, the head jacket, and passing thence to the lower portion of the cylinder jacket, flowing up ythrough the latter and inally passing out more eiciently,
tion with re at or near the top of the cylinder j acket.,
he objects of my invention, therefore, are to cool gas engine cylinders and the like -to supply the coldest water e part near which thehighest temperais produced, and to avoid complicato th ture. tions. y b
will now proceed to describe any/inven- .erence to the accompanying drawing' showing a central vertical section l vof they cylinder and associated parts of a vertical type of cylinder jackets arranged and connected in 'accordance with my invention.
In the drawing, l designates the `cylinder proper, 2 the cylinder head, 3 the piston,4
the connecting rod, l5 a water-jacketed valve cagev forl an: exhaust valve 6, 7 an exhaust mmf-8 the-water jacket of the rcylinder head,
of these ,jackets itis-en 'et' the' United [States of America, and a resident oi Toledo,- county of Lucas, .and 1 have invented certain ,newand nsei'ul Improvements in Engines, of
the jackets of gas gas engine, having head and and the water jacket ot' 'the cylinder. Each has an inlet and an outlet port, and I have shown the outlet port l0 'of the head jacket connected by a pipe l1 eX- tend-ing forwardly of the'cylinder from said port 10 to the inlet port 120i the cylinder jacket, which port l2 is located near the bottoni orn the cylinder' jacket. the head jacket at the inlet port 13, and after flowing through the head jacket passes through port l()` and pipe ll to the inlet port 12- of the cylinder jacket, and iiows up through the cylinder jacket, finally iiowing out. through the discharge port 14 near the top of said jacket. `By this arrangement, the coldest water is in the cylinder head, which is exposed to the highest temperatures, and since the water will still be 'relatively cold when it leaves the head jacket, thereis no opportunity for evaporation in the head jacket and consequent pocketing of steam. Thence the water is delivered to the cylinder jacket. Unly the upper portion of the cylinder is exposed to the extremely high teniperatures to which the cylinder head is eX- posed, and the thicknessy of the cylinder walls is usually ample to conductheat downward through said walls so that overheating of the cylinder cannot' occur so long as there is water 'in the jacket; a higher temperature of the Water in 4the cylinder jacket being permissible, therefore, than in the head jacket.
In general, water will be circulated positively through the jackets, either by means l.of a pump, or as a result' of the water being discharged at lower pressure than that at which it is such means for are well known.
- What I claim is l. -A jacketed engine cylinder comprising separate head and cylinder jackets, the former above the latter, each such jacket pro-vided with inlet j vlet port of the cylinder jacket being near the bottom of said cylinder jacket, the out-let port of said cylinder jacketl being near the top ofsaid cylinder jacket, said cylinder also provided with a duct connecting the outlet port of the head jacket and the inlet port of the cylinder jacket, whereby water first admitted to. the head jacket lowstherethrough vand thence through the cylinder jacke positive circulation, as lthey 2. A'jacketed engine cylinder comprising separate head and cylinder jackets, .the

and outlet ports, the in-' Water enters former above the latter, each such jacket provided with inlet and outlet ports, the
port ofthe heed jacket being n outlet ear the top of 5 index' jacket being der jacket being near the top o jacket, said cylinder also provide duct connecting the outlet port of l0 jacket and the in let port of the :ey
cylin said cylinder d with e the heed linden jacket, whereby water first admitted to the heeel jacket ows therethrough :md thence through the cylinder jacket.
lin testimony whereof have signed this specification inthe presence of two sub 15 scrbing witnesses.
