' Jersey, have invented certain Improvements in Motors, of which the following is a specification.

My invention relates to certain improve.

ments vin Huid-actuated motors having for its object the production of a device of such construction that it shall be relatively light for a given power and shall possess but relatively few moving parts yin comparison to the number of cylinders employed. It is further desired to produce a motor of the above character which shall be efficient in operation, comparatively simple and inexpensive to construct,`and so made as to not be readily injured even by comparatively rough treatment. These objects I attain as hereinafter set forth, reference being had to the accompanying drawings, in which- Figure 1 is a vertical sectional elevation of one form of my yimproved motor, taken through the center line of its main shaft. Fig. 2 is a sectional elevation taken on the line 2 2, Fig. 1. Fig. 3 is a longitudinal sec-- tional elevation of the preferred form of valve employed in a motor of the form shown in Figs. 1 and 2 and Fig. 4 is a sectional elevation of a special form of my improved engine, particularly adapted to operate as an ex losion-engine.

eferring first to the particular form, of

motor shown in Figs. 1k tio-3, inclusive, A is a supporting-base from whose extremities ex- .tend standards a, provided with bearings for On the centhe main shaft B of the engine. tral portion of the base is al main cylindercasting C, and in this are formed the various cylinders, in which operate single-acting istons for transforming the power 'of the uid under pressure to the main shaft. In

. the present instance there are four sets of the cylinders, and each set contains three cylinders, it being noted that the various sets are arranged in pairs. For example, the relatively small cylinders c open on the upper portion of the cylinder-casting C, while another set of cylinders c open on the bottom face of said casting, which is, as shown in Fig 1, so made that the portion in which said latter pistons are formed overhangs the base in orderl'lto permitaccessflthe ,piston-rods to said cylinders. Similarly the set of cylinders c2 are opposite or one hundred and eighty degrees distant, from the cylinders c3, it being understood that in the present instance the motor illustrated-is designed as a quadruple-expansion engine, and hence is provided with cylinders of progressively-varying sizes, there being, as above-noted, three cylinders of eachsize or set. In each cylinder is a single-acting piston, and all the pistons of each pair of opposite sets are connected, by means of rods c, to overhung portions of arms or frames D and D respectivelythat is to say, the pistons in the cylinders c and c are connected to the arm D, while the pistons in the cylinders c2 and c3 are connected to the arm D.

The main shaft B is provided just inside of its bearings'in the standards a, with cranks b and b, upon which the arms or frames D and D are journaled and upon which they are supported, in addition to which their lower overhung portions are supported diy scribed being in each case equal to the length of the stroke of the pistons.

Under operating conditions motive fluid is admitted to but one end of each cylinder, and for'the purpose of controlling the flow of such liquid there is formed in the cylindercasting C a cylindrical cavity concentric with the shaft B, in which is a fixed bushing c5, having within it a rotary valve E, fixed to and compelled to turn with the said shaft B. This cavity, Aand consequently the line of the valve, extends between the two sets of cylinders of each pair and is provided with any desired means (not shown) for preventing wasteful escape of motive iiuid.

There are four passages or cavities opening through the bushing c5 into the valve-cavity and communicating, respectively, with the' four sets of cylinders. These passages are viz.7 e and e-are annular in form and communicate, respectively, with fluid inlet and exhaust passages (indicated at c10 and cu) and have, moreover, openings e2 and e3, respectively, upon the cylindrical surface of the valve E, which openings are so placed as to be in the planes of the passages c and .09. In addition to the above there are in the valve three passages e, e5, and e, each of which extends through and opens upon the opposite portions of the valve, so as to per- Init motive' fluid to pass froml certain of the cylinders to certain others when the valve E is revolved by turning the main shaft B.

In Fig. 4 I have illustrated a modified form of my invention particularly designed to operate as an explosion-motor, it being noted that, as in the machine shown in Fig. 1 to 8, inclusive, the various cylinders are so arranged, that as one piston or set of pistons moves inwardly, the oppositely-placed set of pistons moves outwardly. In this construction a reciprocable bar H extends through the cylinder-castings G and G/ and is provided at its ends with cross-bars h2, connected to the pistons g2 by means of rods h.

The main shaft is indicated at F and is provided with a crank f, having a bearing block or blocks slidably mounted on guide-bars h, connected to the reciprocable bar or arm H. As before, the pistons are single acting, although since the detail mechanism of this particular form of explosion-engine can form no part of the present invention it has not been illustrated further than to show the arrangement of the pistons and their means of connection with the main shaft.

I claim as my inventionl. The combination in a motor of a structure having a plurality of cylinders, each open at one end and arranged with said ends opening away from each other, pistons for the cylinders, a single movable structure connected to the istons and a shaft having an eccentrically-pllaced portion provided with a bearing for said structure, with means for supplying motive fluid to one cylinder and thereafter causing it to pass to the other cylinders in succession, substantially as described.
