`SPIECIF.IQLA'EIQINF forming part of Letters Patent No. 537,646, dated April 16, 1895.
Application filed February 25, 1895. Serial No. 539,626. (No model.)
To a/ZZ whom it may concern.-
Be it known that I, FRANK C. RINSCHE, a citizen of the United States, residing at the city ot' St. Louis, State of Missouri, have invented certain new and useful Improvements in Engines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this application, wherein- Figure 1 is a longitudinal sectional view of my improved engine. Fig. 2 is a similar view, showing the piston in a dierent position. Fig. 3 is a longitudinal sectional view taken at right angles to the lines of section of Figs. 1 and 2, and illustrating the piston in same position shown in F1g.1. Fig. 4 is a cross sectional view on line 4-4 Fig. 3.
This invention relates to a new and useful improvement in engines ot that class which are designed to be run by motive fluid, preferably in the form of compressed air. The piston is provided with three heads, which control the inlet and exhaust of the motive uid, and also a stem which delivers impacting blows upon a tool shank arranged in the end of the cylinder.
In the drawings A indicates thecylinder in the bore of which is arranged a sleeve B, in which sleeve are formed the several ports in the cylinder ofthe engine. The tool shank opening A is formed in the end of the cylinder for receiving the tool shank, into which opening also extends the stem on the piston.
A indicates the inlet port leading into the side of the cylinder and through the sleeve B.
C indicates the exhaust port formed in the sleeve and opening into the cylinder at o o.
D indicates the port leading from one end of the cylinder to a point between the inlet port A and the exhaust opening c.
E indicates the port leading from the opposite end of the cylinder to a point between inlet port A and exhaust opening c.
Exhaust port O leads to the end of the cylinder and opens through a handle base, secured to the cylinder, to which handle base is attached suitable handle for manipulating the engine. The escape ofthe exhaust is controlled by suitable means located in the base of the handle, which means is more fully described in an application for Letters Patent led by me of even date herewith, and therefore no detailed description of the saine will be given here.
F indicates the piston provided with three heads F', F2 and F8, from the end of which projects a stem F into the tool shank opening. This piston is solid and is not provided with any port.
I will now describe the operation of the en gine which willillustrate the manner in which the piston, with its three heads, controls the inlet and exhaust ports.
Motive fluid being admitted into the cylinder through port A, assuming the piston to be in the position shown in Fig. 1, (said port beingillustrated by dotted lines in Figs. l and 2) the motive duid will pass above the central piston head F2 and into port D, to the upper end of the cyli nderforcing the piston down. The air in the lower end of the cylinder will be exhausted through port E, exhaust opening e, and exhaust port O, the escape of which exhaust is controlled, which thereby regulates the speed of the engine. When the piston has completed its down stroke, head F closes exhaust opening c, head F3 opens exhaust c', and head F2 passes inlet port A directing the incoming motive liuid to beneath the lower head of the piston. The motive fluid is now at this port E, which leads to the lower end of the cylinder. The air at the upper end of the cylinder is exhausted through port D, and exhaust c and O. It will be noted that heads F and F3 close ports c and c whenever the heads F2 direct the motive iuid toward either of said exhaust ports, thus preventing the motive uid from blowing through the engine.
Having thus described my invention, what I claim, and desire to secure by Letters Patent ot the United States, is-
l. In an engine, the combination with a cylinder, having an inlet port opening into its side, exhaust ports leading from two points in the cylinder, and ports D and E which lead from the ends of the cylinder to points between the inlet and exhaust ports, and a piston provided with three heads, which co-operate with said ports, substantially as described.
2. In an engine, the combination with a cyl- IOO inder, having an inlet port opening into its In testimony whereof I hereunto afx my side, exhaust port C opening thereinto at c signature, in presence of two witnesses, this Io and c' and ports D, E leading from the ends 18th day of February, 1895. of the cylinder to points between the inlet 5 opening and exhaust openings o and c re- FRANK C RINSCHE speetively, a piston provided with three heads Witnesses: eo-operating with said ports, and a stem on the F. R. CORNWALL, end of the piston, substantially as described. HUGH K. WAGNER,
