IMPROVEMENT IN DVOUBLEPISTON ENGINES.

Specification forming part of Letters Patent No. 107,524, dated September 20, 1870.

.T0 LZZ whom, it may concern Be it known that I, ALBERT W.- MOEEELL, of Niles, in the county of Berrien and State of Michigan, have invented a Double #Acting Piston-Power for Engines or Pumps, of which the following is aspecification.

My invention relates to the combination of three pistons in the same cylinder, and to the arrangement thereof for receiving or applying power in connection with other machinery. The combination is made in such a manner as to dispense with cylinder-heads, and can be simply changed from an engine to a pump by easily reversing the action of the valve. I use but one steam-chest in an engine constructed on these principles, and have the double action of steam or compressed air upon the pistons. To change an engine of this kind into a pump, change the position of the valve so that suction of the pump will be through the exhaustpipe ofthe engine, and the How of the element, whether water, air, yNc., from the pump will be through the supply-oriiice to the engine.

The object of the invention is to produce a double engine in one cylinder.

L In the accompanying drawings, Figure l is a view of an engine embodying the principles of my invention. Fig. 2 is -a sectional view of the cylinder, showing ythe arrangement of the pistons.

O O O O is the cylinder; A B D, the pistons; C E E, the piston-rods; F G, openings from the chest S into the cylinder; H, the valve; K, the supply-pipe to an engine; Q, the eX- haust to an engine. i

Operation: When the pistons A D B have the position represented in Fig. 2, steam passes from the chestS through the orificeG into the `by a connecting-rod and crank.

` l chamber formed -by the pistons A I), and the cylinder O O O O, forcingV the piston A to the position represented by the dotted lines L, and the piston D tothe position indicated by the dotted lines M. The pistons Aand B are secured to the same rod, C. Consequently, when the pistonA is forced to the position L, the piston B must follow to the position N. When the piston D has assumed theposition indicated by M, and B that indicated by N, the valve II is drawn to the front end of the steam-chest, and steam is permitted to enter the chamber inclosed between M and N, through the orifice F, forcing N to B, M to D, and L to A. The pistoirrod C passes freely through thecross-head I?, Fig. l, and issef cured to the cross-head R, from which motion is communicated to the shaft of the iiy-wheel The rod C, Fig. 2, works through a stuffing-box in the piston D. The piston D is attached to the rods E E, which pass through stufngboxes in the piston A, and are secured to the cross-head P, from which motion is communicated to the fly-wheel by connecting-rods land cranks-y` Thus, by the action of steam (or compressed air) between the pistons alternately, continu ous motion is imparted to the iiy-wheel, and a very effective engine obtained.

I claimn y Ihe combination and arrangement of three pistons` in one cylinder, substantially in -the manner and for the purpose herein set forth.

ALBERT W. MORRELL.
