My inventionrelates to internal co1nbustion engines and has a number ot Ob}CtS and a dvantage's'in View. One feature of my rattlinguand making noise.

invention relates 'to that typeof engines employing rotating valving cylinders and has for its object the provision of cushioning means for preventingthis cylinder from In practising this feature. 0t my invention the cushioning means employed is-desirably liquid, being preferably lubricating oil which may be contained in theicrank pit of the-engine and which 'maybe'ted from the crank pit 'for thispurposeand for the purpose of lubricatingall theengine bearings.

The other features of my invention, which are herein shown asbeing einbodied in con- I nection with an engine having a rotating valving cylinder form the subject matter of a division oit the present application Serial No. 125,93J, filed October 16, 1916; One of these additional features of my invention resides iirthe provision of means for rendering the throttl'e valve highly responsive to the action of the engine during cranking speed, the engine operating upon the valve through an electromagnetic responsive device whose responsiveness is increased during ;-ranlnng eed as rou pared witlr ts responsiveness waea the engine is running above cranking speed.

The third object of in illYQlltltJll resides in the provision of means for cutting the engine out of QClIlU1l.\Y ll(ll the responsive device C"TS its control oi'er the throttle ralve by re on oi a short rircuit ot the respons ye deriee or the I opening of theresponsire device circuit, or the breakiug ot the nije' chanical connection between said respon'siredevice'and the throttle valve.

accordance with the invention, some ad' juncts being diagrammatically illustrated;

and Fig. 2 is a View on line 2-2015 Fig. 1-..

Like parts are indicated by similar char- The engine illustrated is a single cylinder engine. The crank shaft 1 has its crank 2 in connection with one end of the pitman 3, the other end of the pitnian being pivotally connected at l with the piston 5. A alve cylinder 6 is rotated in some suitable way as by means of a pinion 7 operated at suitable speed by some engine driven portion, this pinionengaging a spur gear 8 upon the lower end or the cylinder (3. The Valving cylinder may be provided with ports 9 to "control the admission of earbureted air or other gas through the intake port 10 in the cylinder 11 in which the Yalving cylinder: rotates and also to control the passage of gas through the exhaust port 12 in the cylinder 11. The cylinder 11 is desirably pro.- rided with a jacket 13 for the reception of cooling liuid. This jacket is carried upon the upper end of the crank case 14: that contains lubricating oil 15 and which has an annular step 16 at its upper end upon which the lower end of the alving cylinder turns.

An oil pump is shown which includes two meshing pinions 1T, 18 that operate to withdraw oil from the oil-pit and force it upwardly through the passage 19 that discharges at and preferably upon the top of the shoulder 20 which is upon the lower end of the Yalving cylinder but is above the peripheral gear 8. T he top and periphery of this shoulder and the adjacentbody portion of the gear 8 have sung fit with the correspondin'gly shaped adjacent portion of the je list 1 5 so that the oil which is pumped through the passage 19 1nto the space in the jacket 13 that accommodates the shoulder 20 inayuot have ready exit from said" space,

spaceto enable it to act as acushion to reeeire and lessen upward thrusts otthe shoul-' v 'der which accompany corresponding roral rlng cylinder 6 carrying this shoultn explosions and whichenable the the rotating cylinder 6 is guarded against the oilb eing sufliciently trapped in such crank case from whence it is returned. through the passage 19 for the purposestated, oil from the pit being also directed to other bearing portions of the engine if desired. The pump operates to feed oil through the passage 19 at a pressure that will bear down upon the shoulder 20 to promote the cushioning efiect of the oil thus supplied to the spacing in which said shoulder operates.

-The c'arbureted air or other explosive gas is regulated in its How to the admission port 10 by means of a throttle Valve such as a butterfly valve 21. This valve is governed in its position by means of some ,electropivotally connected at 23 with alever 24:

having the same axis of rotation as the valve and with respect to which lever the valve-is fixed. The winding of the electr c-V magnetic responsive device, the solenoid, is in circuit with a source of current that is regulated by the speed of the engine- This source of current, in the embodiment oi the invention illustrated, is in the form ofa gen- 'erator 25 which is driven by the engine.

As illustrated, thesolenoid 22 or other responsive device responds to the voltage output of the generator. As the voltage decreases in response to lowered engine speed the valve 21 opens to supply additional gas to the engine to increase the'engine speed and vice versa. When the engine is being cranked to start it, the response of the solenoid to the voltage then generated should be quicker relatively to the response otthe solenoid to changes in voltage that arises when the engine is in operation. On this account I increase the responsiveness of the solenoid during cranking speed (usually variable) as compared with its responsivenesson running speed. In the embodiment of the invention illusti'atedl accomplish this 'result'by ,reinoviiiga part of the load upon the solenoid when the engine is operable at cranking speed and restore the load to normal when the engine exceeds cranking speed.

Thechangeable portion of the solenoid load is shown in the form of a weighted lever 26 which, for She sal e of convenience, may have an axis co-inciddnt with the aXis of the valve 21, the lever 26, however, being rota.-

' table independently of the lever 24% and said valve. hen the engine is not running or is being turned at cranking speed the lever 26 will rest upon a stop 27. The core of the solenoid carries'a finger 28 that underlies The -gine is at running speed or above cranking speed the finger 28 will be constantly in lift ing engagement with the weighted lever it? so that this weighted lever will then con stitute a part of the normal load of the solenoid, the weight at this! lever being added to the weight of the solenoidcore. When the engine is not operating above cranking speed or when it is at rest the solenoid will drop its core sufiiciently to lower the finger 28 out of lifting. engagement with the lever 26 sothat the solenoid core is then relieved of the Weight o'f'this lever. The solenoid 22, under the conditions; last mentioned, is more responsive to the voltage emanating from the generator. 25 during the cranking brought to running speed. magnetic responsive dev1ce such, for eXample, as a solenoid 22 whose core may be.

working order) at which the finger 28 will engage the contact 29 which is connected with the primary sideof the magneto gen-, erator 30, this contact being normally disconnected from the ground by the'insulation 31. When the finger 28 engages the contact 29 the finger will ground the primary side of the generator andshort circuit it'so that currentmay not be supplied from the secondary side of the generator. through the conductor 32 to." the spark plug 33.-v The finger 28, being in grounded connection with the engine and being attached to the solenoid core, constitutes a switch which operates to throw the engine out of action or to render it inoperative when the solenoid releases its hold upon its core or upon the-valve controlling lever 24, this switch, when released,

serving to alter the condition of some circuit from that condition which is required of such circuit to maintain the engine in action, for the purpose of stopping theengine The drawings illustrating my presentinvention are inclusive of a structure set forth in my co-pending application Serial No. 149,572, filed February 19, 1917, and
