Abstract

291,937. Douglas Motors, Ltd., and Pullin, C. G. May 17, 1927. Cylinders. -In an attachment for engine cylinders to crank casings, sockets 6 on the crank casings 2 engage the cylinders at intermediate positions 12 and at their open ends at 13. Lubricating-oil is circulated in an annular recess 8 between the engaging surfaces to cool the cylinder. The bolts may engage lugs on a collar 9 which abuts the end 10 of the socket, or may engage lugs at the combustion end of the cylinder. A passage connects the crank-casing with the upper part of the recess 8, and drainage holes in the end face of the cylinder or the wall 17 lead the oil back to the casing. Long troughs 18 communicating with the holes may be provided in the cylinder to collect the oil and act as cooling-fins. Lubricating holes 20 communicate with the interior of the cylinder.
