ENGINE.

SPECIFICATION forming part of Letters Patent No. 760,318, dated May 17, 1904.

Application filed February 11, 1903. Serial No. 142,838- (No model.)

To a whom it may concern:

Be it known that we, WILLIAM KENNEDY- LAURIE Dronson, a subject of the King of Great Britain and Ireland, and GIUsErPE AN- TONIO Gnooo'rrr, a subject of the King of Italy, both residents of London, England, have invented certain new and useful Improvements in Engines, of which the following is a specification.

Our invention relates to engines or motors, and particularly to that class of such engines or motors as are usually termed revolvingcylinder engines.

The principal objectof our invention is to provide a simple and eflieient motor occupying but small space in proportion to the amount of power developed by the same, whereby it is particularly adapted for use in motor-cars, automobiles, and in all cases where the utmost economy of space is desirable, although our improved motor is by no means limited to such uses, being capable of advantageous employment in many other ways.

A further object of our invention is to overcome various defects which have heretofore been present in engines of the class referred to.

Our invention consists of the novel construction, arrangement, and combination of various devices and parts, as hereinaftermore particularly described.

In the accompanying drawings, Figure 1 is a transverse vertical section across the motorcase; Fig. 2, a longitudinal vertical section; Fig. 3, a horizontal section, and Fig. 4 a top view of the controllinglever and certain other parts, all as hereinafter particularly referred to and explained.

In carrying our invention into effect we provide a casing comprising an annular portion 11 and sides 12 12, the whole being supported by abase 13. The sides 12 12 are perforated to allow the passage of the shaft 14 and the plug 15, hereinafterdescribed. Four cylinders 16 are provided, which may be integral with each other or otherwise, but in either case are rigidly attached together in the form of an X, each cylinder constituting one arm thereof. The shaft 14 projects from one side of the cylinder structure, and intothe other side and nearly transversely through the cylinder structure passes the plug 15. The inner end portion of the said plug is tapering, and means are provided, as hereinafter described, for keeping the plug always sung in its socket. A bushing or sleeve 33 is provided intermediate the plug and the cylinder structure provided with openings 8.

Each cylinder has at its inner end an aperture 18, which opens into the central opening, in which lies the plug 15. The cylinders are open at their outer ends. Each cylinder contains a hollow or cup-shaped piston 19, the outer portion of which bears a cross-arm 20, to each end of which is attached a rod 21. The cylinders are provided with slots 22, into which the cross-arms 20 pass when the piston moves toward the inner end of the cylinder.

Suitably rigidly secured to the inner sides of the casing are eccentrics 23, around each of which is placed an eccentric-strap 24. The inner ends of the rods 21 are pivotally attached at four equidistant points to the straps 24:. The said straps are connected by arching bridge-pieces 10, tending to keep them revolving always at equal speeds.

Theplug 15 is hollow and isprovided with a longitudinal partition 25, which divides the .interior into two chambers, (designated in the drawings 26 and 27.) Each of these chambers has an opening at each end, the four openings being designated 28, 29, 30, and 31. The function of these openings will be hereinafter fully described. A partition lS extends downward from the rear or inner portion of the longitudinal partition 25, and through this partition 48 are drilled a number of holes or channels 411, which enter a channel 19, drilled longitudinally through the partition 25. These channels 49 and 17 are for containing lubricate ing-oil and conducting the same to the bearing-surfaces. The plug 15 is free to turn on its axis and bears at its outer end a lever 32 for so turning the same. Any suitable means may be provided-as, for instance,.. those shown in Fig. 1--for holding said lever, and consequently said plug, 111 any des1red,pos1- tion. The plug is tapered at its outer end also, and fitting closely over the same is a correspondingly interiorly tapered sleeve 40, provided with an upwardly-extending pipe L1 and a somewhat larger downwardly-extending pipe 42. This sleeve 40 is provided with two lateral lugs 4.3. (See Fig. 4.) From the front of the casing extend forward two rods 44, which pass through perforations in said lugs and are provided at their outer ends with nuts 45. Between said lugs and said nuts are helical springs 46, tending to keep said sleeve always pressed firmly in upon the tapering end of the plug and to keep the plug itself snug in its seat in the cylinder structure.

The operation of our invention is as follows: The opening 28 being connected with a source of supply of steam or other motive power, the same passes through said opening into'the chamber 26 and out of said chamber through the opening 29 into such one of the cylinders as may at the time have its opening 18 in communication with the opening 29. Should neither cylinder happen to be at the time in such communication, a slight movement of the lever 32 will turn the plug sufficiently to bring it into a position in which such communication shall take place. The steam of course tends to force the piston outward toward the end of the cylinder, and thus exerts a pull upon the eccentrics, which causes the cylinder to move sidewise-toward the point where the rods are attached to the eccentric. As the cylinder moves its aperture 18 passes out of communication with the opening 29, and the influx of steam into the cylinder ceases, and the steam then works expansively during the remainder of the stroke. When the cylinder has made a half-revolution, the opening 18 is brought into communication'wth the opening 30 of the plug, and the steam in the cylinder passes out into the chamber 27 and thence into the open air through the exhaustopening 31. It will of course be understood that when the cylinder which first receives the steam moves one-quarter of a revolution the second cylinder has been brought into position to receive steam and that this second cylinder and itspiston then-aid in the work, and that when the first cylinder has made onehalf of a revolution and is in position to exhaust the third cylinder is in position to receive steam, and so on. V a

It will be evident that the direction of the revolution of the cylinder structure and its shaft will depend upon the direction in which the opening 29 of the plug is made to face and upon which one of the cylinders the steam is first caused to enter. 1

The advantages of our invention are obvious. We would particularly call attention,

however, to the fact that as the plug 15 is tapered and spring-pressed it is always steamtight, that the work of the pistons is done by means of pulling only, thus minimizing friction, and to the simple and efiicien-t throttle cut-off device which we have provided.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is as follows:
