ROTARY EXELOSION-ENGINE.

To allwhom if'ma y concern:

Be it known that I, ENRIQUE JUAN'CONILL, a citizen of Cuba, residing at 1 Rue de Presbourg, Paris, in the. Republic of France.

5 have invented newanduseful Im rovements' which the on the main shaft, the piston rods havingeach a roller, which rollers by rolling in a suitable fixed path cause all of ,th

carried by the shaft to revolve.

The annexed drawings illustrate a form of explosion rotary engine constructed according to the invention and comprising six cylinders each' making two explosions for one revolution of the engine.

Fig. 5 shows dia ammaticall the form of the roller path 0 the engine. ig. 6 shows diagrammatically the form of the roller path and the arrangement of the cylinders of an engine with radial cylinders rotating with the shaft havi sixteen cylinders each making four explosions per revolution of the engine. Fig. 7 is a sectional 'ew showing how the plates 5, i aresecured to the cylinder. 'Fig. 8 is a sectional view showing how the 40 stamps u are supported, by the element m;

The main shaft a has keyed to it a hexagonal drum or steel part?) on thesix faces of which are fixed by means of bolts the six cylinders a. Each. east inte ral therewith a segment of an annulus, al these segments, fixed together by means of bolts constituting ,a complete annulus. Each'piston 7 rice a roller g of steel or'other suitable material whichis loosely mounted on a stud f supported by two ears h h solid with the piston. Each piston is further cut away according to two planes perpendicular to the axis of the engine and; moves between two blades '5 21' secured to the cylinder by means of screw as seen. in Fig. 2 and preventing mission ports of these cylinders has (Z is hollowed and carw connected to a bronze contact w Patented Mar. 8,1910. i

the piston from turning on itself. The rollers g are adapted to roll against a roller path 9' formed of steel cast in one piece... This roller path can be fixed to any suitable frame or to the chassis of an automobile. The rolling band on which bear the rollers of the piston is slightly projecting. The form of the roller path is determinedin such manner as to give the best output; to this end the parts of the roller path correspondmg to the compression are formed by gently sloping curves, so as to give a slow and progressive compression, and the parts corresponding to the expansion are formed by rapidly sloping curves so as; to give a" very active expansion. 7

The casing is closed at the sides by two pieces of sheet-metal k is which have central apertures for allowing the rotation and cooling of the cylinders. These metal-sheets are secured by small bolts Z to the rolling way 1. I

t The shaft a is carried by two bearing supports m, m, with four arms fixed. to the rolling way 9' by means of bolts. V

a -To each cylinder corresponds in the part b a chamber at extended by a'conduit oleading to the side of the distribution. During the rotation of the engine, the ports 0 pass successively in front of corresponding ports p, g, p, q, of'thedistributing plate 7' (Fig. 4). The fresh gases are supplied to the ad 72 by pipes s and the burned gases escape t rough pipes '25 leading to the exhaust ports 9, g. The distributing late 1' has two threaded stems a which sli e in' two corresponding holes of the bearing s'upport m. These stems tohold the plate 1n place and prevent it'from revolving. Spiral springs a mounted on the stems u and bearing on the support on force the distribution plate 'bto bear energetically'on the rotating part Into each chamber at corresponding to a cylinder projects the end of a sparking plug fixed to the periphery of a circular eboniteplate 3/ securedto the drum 1); the six bronze con tacts apass successively", during the rotation 105 in front of two small bronze rollers z 2' mounted at the end of ebonite stems 1 articu- "rated on pivots 2 carried by the casing; the. rollers a z are caused toib'ear a ainst the plate 3 by means of a spring 3 an are elec- 110 trically connected to one of the poles of a suitable source of electric current. In front of the plate y is mounted loosely on the main shaft another ebonite plate 4: on which are attached two terminals 5' and 6 connected to the second pole of the source of current. Two springs 7 and 8 fixed to the ebonite plate 4 carry two bronze rollers 9 and 10 against which bear the teeth of a pinion 11 keyed on the main shaft; these teeth by moving the springs apart through the medium of therollers, put them in contact with the 7 screws 5 and 6 and on leaving the rollers maximum the force produced'for rotating the whole rotary part. The roller thus rolls up to B where the piston has come at the end of its stroke. The engine continuing to revolve on account of the speed acquired, the roller rolls up to C andforces the piston to return into the cylinder. During this time the port 0 of the cylinder passes in front of the port g of the distributing plate '2" and the exhaust of the burned gases is produced. From 0 to D centrifugal force alone work, takes causes the pistonto bear on said path and to cause the suction owing to the passage of the ort 0 in front of the admission port p. At 5 the compression commences and lasts until A is reached. It is to be remarked that the compression which is the stroke during which is produced the largest loss of lace slowly, and is produced almost entire y at the moment when another cylinder is at its working stroke. This concordance assures a regular operation of' the engine and almost entirely avoids the dead point. When the roller of the iston reaches the point'A the ignition ro ler 2' touches the contact :0 corresponding to the sparking plug of the cylinder: the toothed pinion 11 in its rotation produces the spark, the explosion is produced in the cylinder and the ogerations previously described are repeate It will be understood that the diametrically opposed cylinders operate simultaneously: the result is that no .fiexion strains are imparted to the motor shaft a and that each cylinder has two explosions to each revolution of the engine, the six cylinders thus giving twelve explosions for each revolution. I

The advance of the ignition may be insured by turning in one direction the ebonite plate 3/ by means of the rod'12 which slides in a sleeve 13 fixed to the frame m. of the The present arrangement allows of doing away with thecrank shaft, and of dispensing with the fiy-wheel, the mass of the moving cylinders taking its place: further, inders are,

that overheating need not be feared and the use of radiators will be unnecessary.

In Fig. 6 is illustrated dia 'rammatically by way of example a form oi engine based on the same principle as the one described but having sixteen cylinders instead of six.

The explosion is produced simultaneousl at four points A that is to say in four cy inders at the same time and four times per cylinder and per revolution. Between two successive points A each cylinder accomplishes a complete cycle: from A to B useful work; from B to C exhaust; from C the cyl on account of their rotation, in contact with constantly renovated air, so

to D suction and from D to A compression and i nition.

Each cylinder giving,

four explosions per revolution, there is thus for the sixteen cylinders, sixty four explosions per revolution. The distributing plate has in this case four admission openings and four exhaust openings. The engine is in this case very regular, the dead points are avoided and on account of the continuity of the engine efforts, the respective dimensionsv of all the parts may be very much reduced, 1

which gives a great lightness with a great regularity.
