To all whom it may concern:

Be it known that I, WILLY SEOK, of Ober- Ursel, in the Kingdom of Prussia, German Empire, have invented a new and useful Improvement in Gas or Hydrocarbon Motors, (for which I have obtained Letters Patent in England, No. 22,834, dated December 31, 1891; in France, No. 218,837, dated January 21, 1892; in Switzerland, (prov.,) No. 4,454, dated December 22, 1891; in Austria-Hungary, No. 21,764 and No. 69,503, dated April 25, 1892; in Spain, No. 13,371, dated May 27,,

1892; in Belgium, No. 99,746, dated May 20, 1892, and in Italy, No. 32,903, dated October 31, 1892,)of which the following is a specification.

My invention relates to an improved construction of a gas-motor, equally applicable to hydro-carbon motors, and the object of my invention is to provide a motor of great simplicity of construction, the working parts of which are so constructed and arranged with relation to each other as to enable their being lodged in a closed casing partially filled with oil, water or other lubricating substance.

By the improved construction hereinafter described, not only considerable economy of space, but also a complete self-lubrication of the working parts are obtained, and, further, the improved motor offers the great advantage that no injury can be done to the attendant or other persons by the working parts, which are all inclosed in the casing, and said invention consists in the novel arrangement and combination of parts hereinafter described and claimed.

In general, the working order of the improved gasor hydro-carbon motor is the same as that of other known constructions; the gas is supplied by a gas feed pipe or by a generator in which hydro-carbon-oil is vaporized; the said gas or vapors are drawn into the machine by the suction of the piston, which simultaneously draws in atmospheric air; the mixture of gas and air is ignited by a flame and an exhaust valve serves to discharge the products of combustion.

In the accompanying drawings, Figure 1 is a longitudinal, vertical section of a gas-motor constructed according to my, invention. Fig. 2 is a cross-section drawn to line A-B. O. D. of Fig. 1. Fig. 3 is a detail side elevation illustrating the mechanism for controlling the exhaust valve, drawn to an enlarged scale. Fig. 4 is a vertical section of the same drawn at right angles thereto. Fig. 5 is a detail side view of the mechanism by which the valve motion is controlledaccording to the varying positions of the regulator. Fig. 6 is a top view of the same. Fig. 7 is an enlarged detail side view of a part of the same; and Fig. 8 represents a gas generator, which however, may be of any known construction destined to replace the gas-inlet-valve, if the motor is to be worked by hydrocarbon-oil, instead of by gas.

In the drawings a is a closed casing, within which the principal working parts of the machine are arranged.

b are top-plates secured tothe casing, which plates being removed, give admittance to the interior of the casing.

c are journal-boxes to receive the bearings 01 of the shaft-journals e, the bore of said boxes 0 may be slightly tapering according to the tapering shape of the bearings d which, being cut in the direction of their length, are forced against each other by the conical bore of the box 0.

f is the connecting rod mounted on the crank of shaft e, and driving the piston g within the cylinder h of the machine.

t' is the top-plate of said cylinder and k the valve through which gas and air are drawn into the cylinder h by the suction of piston g. In hydrocarbon-motors the said valve is is replaced by a suitable gas generator, such as shown in Fig. 8, for supplying hydro-carbon vapors and air to the cylinder h.

Zis theigniting-pipe and m the lamp for heating the same, n the valve for the exhaust of the products of combustion, 0 the valverod, p a spring tending to close the valve 'n, q an extension of the valve-rod 0, serving to open the valve at suitable intervals, under the command of the regulator, as hereinafter described.

r',r ,'r ,r are four gear wheels for the command of the valve, said wheels being shown in a larger scale in Figs. 3 and 4.

s is the regulator of the machine, 25 a disk or wheel with a circular groove in the periphery thereof, said disk varying its position according to that of the governor s.

to, 11?, u are a set of connecting rods which transmit motion from the disk 25 to the parts which command the exhaust-valve n, as more fully represented in Figs. 5, 6 and 7.

The exhaust-valve n, is under control of a cam 11 secured to or integral with a gear wheel r loosely mounted on the shaft 6 at the side of another gear wheel 7-, mounted fixedly thereto. Said wheel 0* gears into a gear wheel 7' loosely mounted on a fixed trunnion of the machine, and to the said wheel r another wheel r is cast or secured, meshing with the loose wheel 4' on the journal 6. The size of the Wheels 1", r r T is so calculated that 0' makes one revolution, while the wheel 7" fast on the shaft e makes two. To the said wheel 1- a disk or sheave o is cast or secured, can rying the main cam w, Figs. 3 and 4, and an auxiliary cam w. The main cam w serves to operate on the exhaust-valve 12 while the auxiliary cam 00 is provided to lift the said exhaustvalve only when the motor is started to permit the escape of part of the compressed gas and air. The said cams w and ac revolving with the wheel 0 have a bearin g against a sheave carried by the extension q of the valve'rod o. The said sheave y is capable of being shifted on its stem by means of a fork 2, as shown in Fig. 3, and, according to the position of said sheave y, it will be struck either by the cam 10 alone, or by both cams w and w during one revolution of the wheel r and disk 1:. If both cams strike the sheave y, the exhaust-valve n will be lifted twice during one revolution of the wheel 1' and part of the compressed gas is permitted to escape before being exploded. The lift of the valve n is further under control of the governor .9 through the medium of the disk 25 and connecting-rods a, n 10", the controlling device acting in the following manner: u and n are double-armed levers turning on suitable pivots and connected by the rod 10 The free end of the lever or rod to engages by a pin or anti-friction-roller into the groove of the diskt of the governor, causing the other arm of said lever 11/ to swing in the direction opposite to that in which the disk t is shifted by the governor s. The rod 1& transmits the corresponding motion to the lever 11, the free end of which carries an inclined surface, which, when bearing against the pawl u, forces the same into engagement with a notch formed or secured to the rod q, whereby said rod is prevented from being lowered by the pressure of the spring 0, and, as long as the said pawl 11, continues in engagement with the said notch u the exhaustvalue 72 is kept open and the downward throw of piston g performs no drawing in of gas and air till the said valve 01. is closed again. Owing to the power stored in the fly-wheel on the shaft e, the piston g will continue to work in the cylinder it till the speed or revolution has diminished so far'as to allow the governor s to return into its normal position, thereby shifting the disk 15 and levers u and u into the opposite direction and throwing the inclined face on the lever u out of engagement with the pawl u. The said pawl being free, is drawn out of engagement of the notch u by a spring, and the rods q, and 0 are free to be forced down by the spring 10 whereby the valve n is closed and the piston 9 draws into the cylinder a fresh quantity of gas and air for being exploded.
