Application tiled November 4, 1902. Serial No. 130,049. (No model.)

Be it knownthat I, JAMES H. HERRON, a citizen of the United States, residingat Erie, in the county o-f Erie and State of` Pennsyl- Vania, have invented certain new and useful Improvements in Air Compressor- Cylinder Water-Jackets; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as willenable others skilled in the artto which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, forming part of this specification.

My invention relates to air-compressor-cylinder water-jackets, and has for its object the construction of a cylinder and the water-A jacket thereon in such a manner that Water entering at a central point at the lower side of the cylinder passes both ways along the lower half thereof and through openings into jacketed cylinder-heads and thence through openings back along the upper halfof the cylinder to and ont of an openingat a central point at the top of the cylinder, thus insuring a constant circulation of water from the time it enters the jacket until it leaves it.

The features of my invention are hereinaf-H ter set forth and explained, and illustrated in the accompanying drawings, in whichM Figure I isan end view of an air-compressor cylinder embodying my invention. Fig. 2is a side View of the same with one-half of the jacket removed on the line so a: in Fig. l. Fig.

.bers B and B2.

so as to divide the lower half ot' the waterchamber vertically, so as to form two cham- At the junction of the waterchambers B and B2 there is a water-inlet E, which opens into the chambers B and B2 at each side of the annular rib a', as shown in Fig. 2, so that water entering thereby flows into both the water-chambers B' and B2. In the flanges A and A2 at the ends of the cylinder I make Openings d cl', leading from the water-chambers B' and B2 into the lower portions of the water-chambers D and D' in the cylinder-heads C and C', and through the flanges A and A2, I also make openings d2 and cl3, leading from the upper portions of the chambers D D into the water-chamber B2 between the upper half of the cylinder A and the jacket B, these openings d, d', d2, and d2 being clearly shown in Figs. 2 and 3, and at the top of the central part of the water-chamber B3, I provide a water-outlet E.

In operation water entering at the waterinlet E passes in at each side of the rib ot into the chambers B and B2 and travels along the lower half of the cylinder A to and through the openings d d into the lower parts of the Achambers D D and thence back through the openings (Z2 and d3 into the outer ends of the chambers B3 and thence longitudinally toward the center of the chamber B3 .and out through the water-outlet opening E". Thus a complete circulation of the water entering at E is kept up until it passes out at E', thereby subjecting all parts of the periphery and heads of the cylinder to the cooling action of constantly-changing currents of water.

Having thus described my invention, so as to enable others to construct` and utilize the same, what I claim as new, and desire to secure by Letters Patent of the United States,

l. The combination of an air-compressor cylinder, radially-projecting flanges on the ends thereof having openings therein, chambered cylinder-heads secured to said flanges and communicating with the openings therein, a water-jacket having water-inlet and water-outlet openings therein surrounding said cylinder and secured to the peripheries of the flanges thereon, longitudinal and annular ribs between the cylinder and waterjacket whereby the water entering the inletopening of the water-jacket is compelled to travel predetermined paths along the cylinder and through the cylinder-heads before passing out of the outlet-opening in the waterjacket, substantially as and for the purpose set forth.

2. The combination of an air-compressor cylinder having openings through the anges at the ends thereof, a water-jacket surrounding said cylinder, chambered cylinder-heads in said cylindercommunicating with the openings in the ilanges thereof longitudinal ribs between the cylinder and the jacket at each 'JAMES H.
