rm... g 7W Clif -U'rnD srarns PATENT OFFICE@ i ALBERT Y. EDWARDS, or SPRINGFIELI), oHIo, AssIGNoR To THnFoos GAS -To' all whom i may concern:

13e it known that I, ,ALBERT Y. EDWARDS, aalcitizen of the United States, residing at efSpringield, in the county of Clark and vvState of Ohio, have invented certain new 1w; and useful Improvements in .Explosive-Engilles, of'which the following is a specifica `ition. U a .la-My invention relates to improvements in IQnexplosive engines and it relates more parneticularly to im rovements `in the arrangement of the exliaust and inlet valves and the cylinder head.- u Y a- 1 The object of this invention is to provide lianA arrangement of the cylinder head and liff Ythe inlet .and exhaust valves so that valves l lof large area may be used in their proper ,relati'on` to each other and to the piping or ',conduits leadin therefrom; the arrangefment being sucfh that the valves will be readily accessible Without disturbing the mother parts which operate in connection Utherewith. i

f A further object of my invention is to so arrange these parts that they can be fully f a andcompletely protected by water jackets and the parts thus be kept cool.

I attain these objects and others, which mwill more clearly appear from the followingv .30 description, by the construction shown' in y the accompanying drawings inwhicli Figure l is a plan view of l,an explosive engine of a three-cylinder type, to which 'my improvement has been applied, one of the cylinders and 'its head being shown in f section. Firr. 2 is a side elevation, partly in "section, of the upper portion of one of the *cylinder heads showing the arrangement of ifthe supply and exhaust ports. Figs. 3 and 404.- are detail views in'section showing the arrangement and construction for supplying `Water to the jacketed valves and the means for disconnecting the same to permit a removal of the cylinder head and valves with out disturbing the piping. Fig. 5 is a sectional'elevation of a cylinder head showing the valve chambers and valves.

Like'parts are represented by similar letfters ofy reference in the several views.

In the saiddrawings a1, a2, 'as represent f the various cylinders.4 Z) is the gas supply -V" pipe or conduit which leads to these various cylinders through branch connections 51,?52, ba. "d is thefexhaust pipe Vwhich connects COMPANY, or SPRINGFIELD, omo, A CORPORATION or `orgia nxPLosIvn-ENGINE.

Y upper or outer end Ports b4 leading-from Patented May with the respective cylinders in asimilar-.55 manner through branchesy c1,- 02, es: These connections, both for thevinlet and the exhaust, are made in. an suitable manner with the side of the cylin er preferablynearits the respectivel supply pipes b1, '62,' bfua'nd similar ports c* tol the exhaust,pipesfovc2 es are formed in the side of the cyl-'nder an surrounded by the cylinder water'ja'ckets'a. Both the su ply and exhaustvalves e and f are locate in the 'cylinder head g,'vvhich is of a peculiar construction, that is,it is formed of sufiicient length to reject into the cylinder beyond the point W '1ere the inlet and outlet ports, b4, 0*, pass through vthe I70 walls of the cylinder and t e cylinder head is provided with similar portae1 and 1, which register with the ports, 6*, c", in t e sides of the cylinder so thatI the supply and exhaust, to and yfrom the valves, pass later-l ally through the' Walls fof thecylinder and into the chambers formed in the cylinder head g. Each of the cylinder heads are identical in construction, hence adescri tion of one answers for-a description of ail.' Surrounding thelports e1 and f1 and the valves, the valve chambers and the valve stems is a Water jacket, g1f,inthe cylinder head, which is suitably'connected,l ina manner hereinafter describetk"withf'the -Water circulation which keeps all' of the'fp'arts cool.'

The connection between theoutsideoffthe a f cylinder-head and the inside of 'the cylinder is preferablyformedbymeans of a ground joint, the parts'being accurately" fitted' so that, when in proper position, a tight -fjoi'nt is secured Without the aid of packing materia] of any kind: lThe valves are-openjand closed to admit the supply and'permit the discharge of the exhaust, in any suitable manner, preferably by the "employment of an arm g2, supported o'na bracket g3 -on the cylinder-head which arm connectsdirectly with the valve Stems g4, a suitable detachable connection, g5, being 'arranged'between the ,-100 end of this arm and the valve voperating rod f` or connection g. The cylinder head will bea-preferably formed with the usual flange g? and secured in place b the usual bolts g8. It is one of thespeclal `features of' importance in engines of'this kind tobe able to have access tothe valves and` the,oy`linder without the necessity of'f'diseonnecting fthe' supply and exhaust pipes or both, and for the water to the Water jacket. It is also desirable (that the water chamber completely surround the valve chambers and also be capable of being drained. To accomplish this I form a connection through the cylinder Wall and through the outer wall of the 'cylinder head, as shown in Figs. 3 and 4, and in this opening I insert a hollow sleeve or' plug It having at its inner end a joint k1 preferably ground to fit a similar opening in the outer Wall of the cylinder head, thus `making a tight joint between the said cylinder head and the said plug or sleeve without the aidof packing material of` any kind.'`

This plug or sleeve is preferably provided with flanges ha and bolts h4, by means of which it is securedin place after the manner of a gland. To the outer end of this plug 2o or sleeve is secured the circulating pipe from the Water supply h5, this connection` furnish a device in which valves of large area for the inlet and exhaust are provided which may be placed in close proximity and side by side, also the valves, chambers and stems are completely surrounded by a water jacket :1nd,by disconnecting the arm gzat g5 and .cylinder-head, with the valves, eanbe removed Without disturbing any of the other parts. In disconnecting the water connection z. it is only necessary to loosen the same sufficiently to allow the end of the sleeve or connection It to be withdrawn to a point within the inner periphery of the cylinder', which will be permitted bythe resiliency of the pipe connection h5 without any other disconnection. Further, by lhaving the plug h communicating with the extreme lower end of the Wat'er jacket of the cylinder head, the head may be completely drained, and, also, by the construction described, the head may be drained entirely-independent of the cylinder jacket. The advantages of this construction are obvious and, other than mentioned, need not be described in detail.

' The supply and exhaust are permanent and pass laterally through the walls of the cylinder and connect withl the lateral ports in the cylinder-head and thus direetlly to the valves, securing large and simple passageways free from friction and insures both a perfect exhaust and inlet. The ease and facility of 'the removal-of the cylinder-head withoutl disturbing the other parts, while keeping all'of vthe parts completely waterj acketed, is especially advantageous.

the Water connections jl and L, thev Having thus described my invention, I claim:

l. `The combination of'a cylinder and a removable extended cylinder head located in the end thereof, a water jacket for said cylinder and a water jacket for said head, said jackets being independent of each other and non-communicating, and a water connection for said head water jacket extending through the walls of said cylinder, substantially as specified.

2. The combination of a cylinder and a removable extended cylinder head located in the end thereof, inter-communicating ports between the cylinder and head, anindependent water jacket for each of said parts, said jackets being non-communicating, and a Water connection communicating with the head water jacket vand extending through the jivals of said cylinder, substantially as speci- 3. The combination of a cylinder and a removable extended cylinder head located in the end thereof, independent non-communicating water jackets for said head and cylinder, respectively, and a water connection communicating with the lower end of the water jacket flor said head and extending through the walls of `said cylinder, substantially as specified. i
