Specification oi Letters Patent,

Application filed April 25, 1967. Serial No. 310,277.

To all whom it may center n:

Be it known that I, (lirAitLns R. GREUTER, a citizen of the United States of America, residing at- Wilkes 7 Barre, Pennsylvania, have invented new and useful Improvements in Explosive-Engines, of which the following is a specification.

This invention relates to explosive engines and has s ecial reference to certain new and practica improvements in t'he valve motinting therefor.

To this end the invention primarily has in view a novel mounting of the inlet and exhaust valves for. explosive engines whereby such valves and their accessories are maintained thoroughly cooled so that the same will not become sullicientlyv hot to scale or pit, thereby obviating the necessity of regrinding the valves as is required in the ordinary types of valve mountings for explosive engines.

A further and distinctive object of the invention is to provide a novel arrangement of the cages for the inlet and exhaust valves of an explosive engine, whereby the said cages "are exposed directly to the cooling influence of the water in the water jacket of the cylinder, thus providing means which positively insures the proper cooling of the exhaustvalve.

A further object of the invention is to so mount the valves in. their related parts as to permit of ready assembling and also ready removal for purposes of repair or adjust"- ment and to provide for a water tight connection'between the walls of the cylinder and the valve cage,

With these and many other objects in view, which will readily appear as the nature of the invention is better understood, the same consists in the novel construction, combination, and arrangement of parts'hereinafter more fully described, illustrated, and claimed.

The essential features of the invention involved in carrying out the objects above indicated are necessarily susceptible to structural change without departing from' the scope of the invention, but a preferred embodiment thereof is shown in the accompanying drawings, in which the figure ofthe drawings is a sectional view of the head porshowing the same equipped with the imthe present invention.

In carrying out the present invention. no radical change is required in the valve construction orin the valve controlling nicchan ism of the inlet and exhaust valves associated with the cylinder head of the ex losivc engine, so for illustrative purposes t ere is shown in the drawings the head portion H of the cylinder of an explosive engine, which head portion includes in its construction the -inner and outer cylinder wall 1 and 2 arranged in spaced relation to provide the usual inclosed water jacket 3 enveloping the cylinder body and its head, and designed to have water circulated therethrough for cool ing purposes.

It is preferable in adapting the improvements to the cylinder head of an explosiveengine, to arrange the inlet and exhaust valves 5 and 6 respectively at opposite sides of the cylinder head, but performing the usual functions of admitting the explosive.

mixture to the cylinder head, and exhausting spentproducts therefrom. l ;re equip ment and mounting of each. of said valves 5 and 6 are the same, the only difference to be noted residing in the fact that the exhaust valve and its equipment are arranged at the side of the cylinder head, (opposite the sparking mechanism S,) where the most water is located, and thereby giving the: exhaust valve and its cage the benefit of more effective cooling from the water in the water jacket of the cylinder.

Referring articularly to the mounting of the opposite y arranged valves 5 and 6, it will be observed that the cylinder head is provided upon opposite sides thereof with inclined valve supporting sections within and ilpon which sections are designed. to be mounted the cages 7 for the valves. Each valve cage 7 essentially consists of a cylindrical body provided therein with a centrally arranged guiding tube 8 accommodating the sliding valve stem 9 connected at its inner end with the valve proper, the outer end of each valve stem 9 carrying a contact head 10 adapted to be engaged by the tappet .11 car ried by a rockerarm 12 mounted on a rock shaft 13 to which is also connected a second rockervarm 14 carrying at its free end a contact roller 15 for engagement with the cam 1.6 on the cam shaft 17. These parts are dupli- Gatedfor the oppositely arranged valves, thereby comjleting a valve controlling mechanism, w iich by reason of the arrangement of th cams on the cam shaft, prov des means for the alternate opening and closing of the inlet and exhaust valves in proper time all of which will be readily understood by those familiar with the art without further description. However, in this connection, it may be further noted that there is associated with each of the sliding valve stems 9 a bowed valve closing spring 17, one

- formed at the inner end of the valve cage 7 for said valve. Also at its inner end each valve cage 9 is provided with an exteriorly threaded fastening neck 22 engaging the threaded receiving opening 23 provided in the inner Wall portion 1 of the inclined valve supporting section of the cylinder head. By reason of forming the exteriorly threaded fastening neck 22 there is provided on the inner end portion of each valve cage 7 an external joint shoulder 24 adapted to smoothly and tightly bind on the ground joint face 25 turned on the outer face of the inner wall section 1 of the cylinder head. This provides an eiiective ti'ht joint between. the valve cage and sai wall section and prevents. leakage at this point; while at the same time exposing a material portion .of the body of the valve cage to the water within the water jacket 3.

The cylindrical body of each projects upwardly from its connection with .the inner wall section 1 across the water jacket space 8, and through a holding opening 26 formed in the outer wall section 2. Said holding opening 26 is formed in the base of what may be termed an interiorly threaded socket 27 accommodating therein an exteriorly threaded acking" nut 28 which lies wholly within t e socket and is adapted to beturned against a co per or equivalent gasket 29 seated on the ase of the socket and binding a ainst an exterior bearing shoulder 30 provi ed on the body of the valve cage 7. By reason of this construction, it will be observed that the tend; ency of the packing nut 28 is to force the valve cage 7 against the ground joint face or shoulder25 of the inner wall section thereby maintaining,asecure' water tight joint connection between the valve cage body and the inner and outer wallsections of the cylinder head, while'a't the same time exposing a 1 material portion of the valve cage body to :water jacket,"

the cooling influence of the water=in the Th5 Outer projecting portijbnofeach valve valve cage 7 cage body 7, lying beyond the outer wall of the cylinder head, is provided with an outer closed head 31 and with a side port or ions 32 in communication with a semi-tubular pipe ring 33 encircling the outer projecting portion of the valve cage body. The semitubular pipe ring 33 for each of the opposite valve cages, is provided at one side with a coupling neck 34, and to the couplingnccks 34 of the opposite pipe rings are respectively coupled the inlet and exhaust pipes of the engine, which pipes are desi nated respectively by the numbers 35 an 36.

In connection with the above features, it will be noted thatcach valve cage body 7 is .provided with an outer threaded extremity 37 receiving thereon an internally threaded ring nut 38 binding upon and holding in position the pipe ring I claim:
