osolLLATiNG ENGINE.

SPCIFICATON forming part of Letters Patent No. 501,991, dated July 25, 1893. Application led October 7, 1892. Serial No.4481165- (No model.)

To @ZZ whom it may concern:

Be it known that I, MILES H. DELANY, a citizen of the United States, and a resident of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Oscillating Engines, of which the following is a specification.

My invention relates especially to that class of oscillating engines in which the working parts are inclosed within a box or casing for protecting such parts against dust, duc., and permitting the water of condensation of steam escaping from the cylinders to be utilized as a vehicle for oil for lubricating the parts by retaining the water at a fixed level in the casing.

My invention consists of certain novel features of construction for permitting a discharge of the surplus water of condensation vertical cross section thereof on the line --m Fig. 2.

Similar letters of reference indicate similar parts.

The letterAindicates the bed of the engine forming also a part of the casing, and B indicates a shell forming the remainder of the casing, these shells being fastened tothe bed, usually by screw bolts B at the top and bot tom thereof.

C indicates the engine cylinders, D the piston iitted therein, and F a crank having a wrist pin F to which both pistons are joined by a suitable coupling F2 for imparting the required motion to the crank, the latter being xed to the engine-shaft G, which is mounted in a suitable bearing G of the bed. The cylinders C with their pistons D as well as the crank F and conco\mitant parts are inclosed in the casing formed by the bed A and shell B and the water of condensation arising from a leakage of steam from the cylinders accumulates in the easing so that it may be utilized as a vehicle for oil forlubrieating the vWorking parts 'as for example the crank pin F and its coupling; the water being kept at a fixed and predetermined level by the means to be next described.

To'the bottomof the shell B, of the casing is connected the upper end of a vertical pipe I having a cap I' at its other or lower end and to the top of such shell is connectedv the lower end of a similar pipe J having a cap J at its upper end, each of these pipes coinciding with the other as to its axis. The pipeIwith its cap forms a water chamber in the bottom of the casing, while the pipe J with its cap, forms a steam chamber in the top of the casing, and at a point concentric with said two pipes is a third pipe K serving to discharge water and steam from the respective chambers. The discharge pipe K rests on the cap I of said waterchamber, it being usually fastened thereto whence said pipe extends upward to a point near the top of the steam chamber J, and said pipe is open at both ends, its lower end-opening being formed by perforating the same, as at Z, near the lower end. Within the discharge'pipe K is another pipe N, which extends from a point intermediate of the top and bottom of the casing, downward through the cap I of the waterchamber, is supported by that means and which forms primarily an overlap pipe for the water. The portion of the shell B of the casing, receiving the pipe J of the steam chamber, is a cap-plate B2 which is fitted on an opening in the top of the shell serving to afford access to the interior of the casing. s

It will be readily understood that the level of the water in the casing is determined by .the position of the upper end of the overflow combination with the shell B forming part of chamber, an overiow pipe N within the disa casing inclosing the Working parts, of awacharge pipe, extending through the base of lo ter chamber, formed on the bottom of said said Water chamber, substantially as and for easing, to extend below the bottom, a steam the purpose described.
