Specification of Letters Patent.
- ted :A ppHoation filaengm 30.1906. seen-n0. 278.416.
To all, whom it may concern: Be it known that we,P;l w'L Fl SCHRYER and DANIEL C. STOVER, citizens of the United States, residing at Freeport, in the county of,
Stephenson and State of Illinois, have in vented new and useful Improvements in Internal-Combustion Engines, of which the following is a specification.
The invention relates especially to means whereby the admission valve is positively prevented-from opening at improper times.
In the accompanying draw1ngs,Figure 1 is a plan view of an engine rovided with my devices. -Fi 2 is an en elevation of an enginecylin er provided with the same devices. Fig. 3 shows the devices of Fig. 2 seen from above, the cylinder head bein in section on the line 33, Fig. 2. Fig. 4 1s a section on the line 44, Fig. 2.
In these views, A represents an engine cylinder provided with an admission valve B and an exhaust valve 0 which is opened at proper times by a rocking lever D, actuated by a rod D itself caused to reciprocate longitudinally by devices connected with the engine or its shaft.
' As in other engines of this general class, the exhaust valve is constantly acted upon by a spring which when the valve is closed yieldingly resists its opening and which when the valve is open tends to close it. In this instance, such spring is shown as a helical coil, 0, inclosing the stem of the valve gases in the the-valve stem, and re-acting against that portion of the structure in which said valve stem works. When the rod D moves in the proper direction, it swings the lever D upon the central pivot of the latter, and thereby the free end of the lever is pressed against the free end of the stem of the valve C. The pressure thus exerted upon the free end of said-valve stem exceeds the resisting power of the spring and such outward pressure as cylinder may chance to put upon the inner face of said valve, and as, but for such resistance of the spring and gas pressure, thevalvc and its stem are free to move inward, the spring yields and the valve opens, under t e ressure of said lever. A spring B acts in 'ke manner upon the inlet valve but yields and allows the valve to open when a partial vacuum is created in the cyinder by the movement of the pisvalvaand is again swings in the contrary d" ton. :This valve is howe er. and positively loc-L'rr ever the lever swings to cnioc l To .a one plish this automatic locking and unions the admission. valve stem is provided disk or catch E at its outer end, t gaged by a latch pivoted at r the cylinder and normally pressed against the stem, beneath the e means of a spring G. 50 long as i holds the latch beneath or in en with, the catch, the stem is efi'ect vented from mo drag-inward, and i valve is positively locked in closed 1 This position of the latch is permitted the lever is swung toward the exhaust W stem but when it swings in the opposite tion, a projection upon its inns pushes the latch outward disengaging. .m Q the catch and leaving the admi:- v unlocked and prevented from open by the spring. in other words sion valve is closed. and securely lo ing intervals alternating with l and admission is possible only times, the valve being locked age ing at other times.
What 1 claim is:
1. The combination with an engine der having spring actuated inlet and em valves, of a centrally pivoted lever arranged to swing toward and from the exl'iaust valve, to positively ooen it and then. release it, a spring-actuated lat-ch. rigidly lociri g the in let valve when the latter closes, and a device borne by said lever and adapted 'in'ee latch out of locking position. when the lever moves from the exhaust v vo.
2. The combination. v. 1 an T lilfi der, of a spring closed exhaust valve a closed inlet val e ha ing a catch upon stem, a; suing-actual? d latch said catch and locking the in closed position, and iiilQIlgil1-t arranged to string tov d exhaust S ud latch out oi. iockinsr I der to swing transversely into engagement In testimony whereof we afiix' our signs- ;with said catch, and an engine-actuated tures, in presence of two subscribing wit- .ilfvei' 'ivoted between its ends to the engine nesses.
