HYDROCARBON-MOTOE.

Specification of Letters Patent.

Patented Feb. 10,1914..

Original application led July 26, 1909, Serial No. 509,594. Divided and this application led July 25,

1913. Serial No. 781,190.

To all whom t may concern Beit known that I, RUSSELL HUFF, a citizen of the United States, and resident of Detroit, in the county of Wayne and State of Michigan have invented certain new and useful Improvements in Hydrocarbon- Motors, of which the following is a specification. y

This application is a division of application Serial No. 509,594, led July 26, 1909,

and .the invention relates to hydrocarbon motors of the sleeve valve type. e

One of the objects of the present invention is to arrange the valve sleeves so that the-y are free from the side thrust of the pistons.

Another object of the invention is to provide an annular valve chamber that is closed at both ends and is entirely separate from the combustion space of the" motor except through the inlet and exhaust ports which are controlled by the valve sleeve or sleeves within the chamber.

Another object of the invention is to so constructa motor of the sleeve valve type that the inner and outer members that form the annular valve chambers will-have no joints throughout the parts on which the valve sleeves slide and with the joints between these members located at the upper ind lower ends of the respective valve chamers.

Another object of the invention is to so construct a motor of the sleeve valve type that the spark plugs or 'other ignition devices and the water connections for the head may be located in the top of the head in an accessible position, While at the same time the head and the surrounding casing, between which the annular Valve chamber is formed, may be vsuitably connected to close the upper end of the valve chamber.

Another object of the invention is to make the parts forming the valve chambers readily detachable to facilitate machining and to make the valves easily accessible.

Other objects will appear from the following description taken in connection with the drawings, which form a part of the specification, and in which,

Figure 1 is a vertical sectional view of a motor embodying this invention, being taken on the line 1-1 of Fig. 2; and Fig. 2 is a section on the line 2-2 of Fig. 1, with parts shown in plan.

and 11, and it is closed at its upper end by means connecting the adjacent upper ends of said members 10 and 11. This connecting means may be of any suitable form so .that it does not extend entirely over the top of the inner member, and it is shown in the form of an annular lange 14 which fits the `topi of the outer member and is secured, as by screws 15 and a ring 16, to the upper end of the inner member. A ring 17 engages the upper side of the ange 14 and is clamped,

against the flange and removably secured to the upper end of the member 10 as by bolts 18. The flange 14 thus forms a closure for the top of the valve chamber 12 and the inner and outer members are readily detachable.

The upper part of the inner member 11 forms the head of the cylinder, having a transverse water-cooled part 19 which performs this function. By reason of the fact that the connecting means between the upper ends of the members does not cover the part 19 of the inner member, the spark plug or other ignition device 20 may be arranged in the center of the part 19 and a water connection 21 may also be mounted in this part. Thus both the spark plug and the water connection are accessible through the ring 17 and its cooperating connecting members. The spark plug is thus arranged approximately in the center of the combustion space 22 of the motor where it is most effective and the water is taken from the `extreme upper end of the, inner member so` that no air pockets in the'water acket are possible. vThe inner member 11 is formed with inlet vand outlet ports 23 which communicate with the combustion space 22 and with the valve chamber 12 substantially midway between the ends of the latter, and the outer member 10 has ports 24 which also communicate with the valve chamber 12 and, are alined with the ports 23. As shown, there is a circulation of water around the ports 23 through ducts 25 in the connection 26 formed between the parts of the inner member 11 which are above and below the ports 23. llt will be understood that the walls of the valve chamber 1,2 are accurately machined and ground and if desired suitable packing rings 27 and 28 may be employed for the purpose of more perfectly closing the ports in the valve sleeve about to be described.

One or more valve sleeves `may be arranged within the valve chamber 12 for the purpose of coperating with the prts 23 and 24 in the inner and outer members respectively, and inl the drawings two such sleeves, 29 and 30, are shown. These sleeves are respectively provided with ports 31 and 32 which coperatie with the ports 23 and 24 as above suggested, for the purpose of opening and closing these ports to operate the motor on the four stroke cycle.

The cylinder of the motor may be suitably arranged below the valve chamber forming members 1() and 11, and in the present instance the cylinder 33, in which the piston 34 slides, is formed as an integral part of the inner member 11, being suitably waterjacketed, as at The whole of the motor as above described is mounted upon a suitable crank case 36, the upper part only of which is shown in the drawings, and diagrammatically illustrated are the connecting V rod 37 and crank shaft 38, which latter is of course mounted in the crank case.

The valve sleeves 29 and 30 may be arranged to slide in any suitably manner upon their respective ground surfaces, and in the drawings the inner valve sleeve is operated by means of a sliding rod 39 connected to an eccentric 40 by means of a connecting rod 41. The outer valve sleeve is provided with an extension 42 which is connected to a rod 43 by means of the reinforcing piece 44. The rod 43 is operated from an eccentric 45 by means of a connecting rod. 46. The eccentrics and 45 are mounted upon the eccentric shafts 46 which are driven from the crank shaft by means of the usual two-to-one gearing 47.

It is believed that the operation of the valve sleeve in the embodiment of the invention shown will be obvious, it being understood thatfin -the drawing the piston and the other working parts are shown in the upper dead center position of the exhaust stroke and the ports in the sleeves and in the inner and outer members will coperate at the proper times for the operation of the motor on the four stroke cycle. It will be seen that the valve sleeves are so arranged that they are not subjected to the side thrust of the pistons, and being located in carefully closed chambers, the walls of which are unbroken save for the ports and rings, and

which are closed above and below the valve sleeves, leakage along the surfaces of the valves will be reduced to a minimum.

lt will be understood that suitable means for feeding oil tothe above sleeves may be provided as in the motors sh'own in said application, Serial No. 509,594, and, if desired, other features of said motors may be adopted in cooperation with thc motor shown in this application. For instance, while l have shown the sleeve operating mechanism as mounted below the cylinder, it will be obvious that other operating mechanism may be employed and if desired located above the cylinder, as shown in said application. It is also to be understood that this invention is not to be limited to a plurality of superposed valve sleeves for each cylinder, since an engine of this type may be operated with a single sleeve or with a plurality of sleeves which are not superposed. It is further o bvious that various changes may be made in the details of construction without departing from the spirit of this invention, and it is, therefore, to be understood that this 1nvention is not to be limited to the specific construction shown and described.
