- Application filed June 18, 1912. 'SerialNo. 704,310.

T 0 all whom it may concern:

.Be it known that I, JOHN O'r'ro Hansen, J r. a citizen ofthe United States of America, l

residing at Detroit, in the countyof \Vayne, State of Michigan, have invented certain new and useful Improvements in Rotary- Valves for Explosion-Engines,of which the following a specification, reference being had therein to the accompanying drawingsqij The lnvention relatesto explosion engines I of that type employingfrotary valves", andthe invention consists'in the peculiar con.

struction of the 'Ivalve and the construction and arrangement of: -the same; in relation to the explosion engine as hereinafter set forth.

In the drawings Figure 1 is a,'vertical' cross section through an explosion engine to which "the improved construction of valve is applied. Fig. 2' is a section on line we 'j s a: sectiononl li n Fi 1. a I

' is the; engine casing which may if be' either a single cylinder or. a plurality 'of'in-' tegral, multiple cylinders; B is the cylinder head; and C are'rotary; valves. in'said head extending [transversely thereof, and fcon-.

trolling inlet and exhaust port"s -D. and E; The valve C is preferably in the form of a hollow sleeve, which has portsfF 'andF'. for registration respectively with theports D and Within .the sleeve is a n o n-rota-' tive sleeve or hollow coremember H, which vis correspondingly ported. and which corn-v municates through its outer end with the inlet manifold or exhaust. I Asshown this hollow core memberis formed in two sec-' tions'H and H, extending inward from opposite ends of the hollow sleeve C, and having'flanges H for overlapping the ends of sa1d sleeves and forming agas-tight joint therewith. The inlet manifold I and ex= ha lsli' conduit J are secured tothe engine" casing so as to cOm'munioatewith the holy low core members asisho'wn inF g. 1.

Surrounding the hollow sleevegvalve' is a valve case K, while the latter is surrounded by a water-jacket L,also"formed in the head t B. At the top of the head is a longitudinal channel in whichv is located a rotary shaft M having a spiral gear N thereon, and which is in mesh with a. correspondin spiral gear 0 upon the rotarysleeve C... hus all of the valves may be simultaneously driven in proper timed relation, while the channel I Specification of Letters Patent.

. 1 provides a means of feeding lubricant. to

the valves. a v

Q is a cap arranged above the head B, and

which is preferably hollow and-may be convcniently used as a-lubricant storage rece tacle.-

Vith the construction as described in op- "eration, the valve ()Will control the ports I): and E and in their closed position will Qform'aj double seal. by-reasoniof. the bearing on the innerv core member H. as well as that upon-the outer valve case K. \Vhen the.- va'l've is subjected to the pressure of gas Within the; explosion; chamber it will. be

forced away from the seat upon the outer case K, but the same movement will cause a which-Will prevent leakage.

The sections H and H of the core members areprovided with heads at their inner ends, .which separate the exhaust conduit from the inlet, and to permit of'adjustment :tor taking up the wear these sections are preferably-clamped together by a bolt- R.

, Wh'atlclaim as my invention is:

'1.- Inan e'xplosion engine, the combina- Qtion with a'rotary, ported'sleeve-valve, of a hollow core'member formed of a plurality Off sections ,insertible from opposite endsof the rotary"valve, ;said, valve beingseated on said core member and said plurality of core sections having their inner adjacent ends secured together. t

2. In an explosion engine the combination with the engine cylinder; of a rotary hollow, ported sleeve-valve extending transversely 1 tighter lit to the inner core memberll,

of sa'id'cylinder, a hollow ported core within said sleeve, inlet and exhaust conduits connected. with said engine cylinder at opposite ends of 'said'hollow core, and means centrally "engaging said rotary sleeve for driving the same.-

Inan'explosion engine the combination with the engine casing, having a transmeans engaging said valve intermediate its ends for driving the same.

' "gine cylinder,

- 4. In explosion e ngiriej'the combine tion with an engine casing of a head therefor, having a transversely extending cylindrical valve "case therein, a rotary 'ported sleeve valve withinsaid case, a hollow core member formed in separate sections, engag: ing said hollow sleeve valve from opposite" portedsleeve valve within said valve case,

ends thereof.

In an explosion engine, having trans versely extending cylindrical valve case therein, open at its opposite ends, a rotary ported sleeve-valve within said case, hollow core members extending Within said sleevevalve from opposite ends thereof and flanged to overlap the ends of said valve,

means engaging said sleeve-valve intermediate its ends, for driving the same, and external inlet and exhaust conduits connected with the casing at opposite ends of said hollow core members.

6. An explosion engine compr sing the ena detachable head for said cylinder, having a transversely extending cylindrical valve case therein, aqrotary ported sleeve valve within said case, inlet and exhaust conduits communicating with the 'opposite' ends of said valve,'a drive shaft extendmg transversely of the axis of saidsleeve valve arranged in a groove'in the 1 upper portion of said head, intermeshing 30 spiral gearson said shaft and said sleeve, and a cap for inclosing said shaft.

7. In an explosion engine the comb nation with the engine cylinder of a detachable head therefor, having transversely extendlngvoyllndrlcal valve case therein, a rotary hollow core members Within said 7 sleeve valve, and engaging the same from opposite 8. In an explosion engine, the combiner tion With a rotary ported sleeve-valve, of a hollow core member formed of a plurality of sections insertible from opposite ends of the rotary va'lve, said valve being seated on said core member and said lurality of] core sections being secured in xed relation to each other. f
