Abstract: 17,634. Pettee, E. E., and McCutchan, J. J. Oct. 4. Radial-cylinders engines.-The engine is of the. type in which the cylinders open into a central casing forming an exhaust chamber, and lubrication is effected by oil carried along with the steam. The oil in the exhaust is caught in a separator contained inside the casing, and is continually re-used for the lubrication of certain parts of the engine. Fig. 4 shows a section through one of the two pairs of cylinders, and Fig 2 shows the distributing-valves and gear. The cylinders b open into the central casing c, closed at one side by a cover d carrying the main crankshaft bearing e, and at the other side by a cover g, attached to a flange f, and carrying an auxiliary bearing q. The pistons of opposite cylinders are connected in pairs by arms r and yokes or slotted crossheads t enclosing brasses encircling the crankpin. The motive fluid is distributed from the inlet conduit i by plate slide valves k, kept against their seats by straps k<1>, and all operated by yokes s and brasses s<1> embracing an eccentric e<2>. The cover g, which is formed with the oil separator, is shown separately in Figs. 5 and 6. The exhaust passes into a chamber u through openings u<1> on its way to the exhaust branch o, and deposits the oil it contains on a quantity of baffle material, which may be in the form of small springs v. The collected oil is supplied through suitable ducts to the bearing q, and also through the oblique duct w from the end of the shaft to the crank-pin and crossheads.

Inventor: ZIMMERMANN OTTO
Filed: 1901-03-19
Granted: 1901-06-08
Abstract: 5822. Zimmermann, O. March 19. Motors operated by expansion or contraction of liquids by heat or cold. -By suitably-arranged displacer pistons a heated and a cooled liquid are caused to flow in opposite directions through a tubular apparatus, whereby the cooled liquid is heated and expands, and the heated liquid is cooled and contracts. The two liquids are in chambers in communication with the spaces on opposite sides of a working piston, which may either be in a separate working cylinder, or by a suitable proportionment of parts may also act as the displacer. Fig. 2 shows a form of the invention in which the displacer pistons a, b, for forcing the liquid in the space W and that in the space K in opposite directions through the tubular heatexchanger, work in cylinders separate from the working cylinder P. The working cylinder P in this example is furnished with a slide valve d, by which its opposite ends can at appropriate periods be put into communication with air vessels E, F. The lower-pressure ends may be put in communication with a stand-pipe at atmospheric pressure, instead of with an air vessel. Fig. 4 shows an example in which the displacer and working pistons are the same pair of pistons a, b. In this case, valves are provided for causing the liquids to flow through the heat-exchanger always the same way.
