off member in a closed position relative to the manifold inlet pipe.
Referring to the drawings 1 -designates a portion of an internal combustion motor, 2 the cam shaft gear which meshes with the crank shaft pinion, not shown, said gear, crank shaft and 'pinion being ordinary relative to internal combustion motors, said gear 2 belng mounted on the cam shaft 5', and 1s enclosed in the housing 6.
Mounted on the cam shaft 5 outside of the spur gear housing 6 is a pinion 7 said pinion meshing with an idler mounted on the stub sha t 9, and meshing with said gearing 8 is a pinion 10 which has the same ratio as the pinion 7, said pinion 10 vbeing mounted on the timer shaft 11,.
Mounted over said gearin s 7, 8 and 10 is a suitable housing 12 to -which is secured a front plate 13. Mounted on the extending end ofthe shaft 11 outside of the 'front plate 13 is a contact maker 36, which is co-operable with the timer 37 mounted thereover.
The shaft 11 parallels the crank case,'not
shown, and slidably mounted on said shaft at the end opposite to the gearing 10 is a sleeve 14, said sleeve being slidably secured to thel shaft by the key 15. Formed on one end of said sleeve 14 is a collar 16, having an annular groove 17, and formedfpn the .of said arms being secured toa collar 21,
whichuis rigidly secured to the shaft 11.
pair of end guides 22 is a cross head 23, an extending from said cross head, intermediate of its ends, is a bifurcated member 24, the lower end of said biurcated -member straddling the reduced ortion 25 of.the collar 16. 'p
' Pivotally secured to the cross head 23 at 26 is one'end of an upwardly extendinglever27, said lever being slidngly and swi'in ngly supported in a guiding member 28.
he upperv end of the lever 27 is spit'as designated at 253i and mounted in said sp t portion and secure thereto is one end of an upwardly extending leaf spring -'30, said lever 27 and leaf sprm 30 forming a toggle lever, the upper end o said spring 30 having a bearing portlon 31 .which is pivotally secured to one endl of a 34, and carried by said shaft 33 inl said pipe carried outwardly, thereby exerting a pull' rocker arm 32 which is rigidly mounted to a shaft 33, said shaft being mounted in opposing sides of the gas manifold inlet pipe 34 is a butterfly valve 35.
` As afore related in the objects of this invention, 'this improved cut-off mechanism is designed so as to prevent a vehicle from attaining a higher speed of travel than the proper mileage per hour allowed by law, as it is well known how hired operators of automobilesfquite often drive the automobile,
.which is in their care, to the limit.
.In the o eration of this improved device, when a' ve icle equipped with the same is run at a normal speed, the butte'ri valve 35, which is located in the manifo d inlet pipe is in a position shown in dotted lines A, in Fig. 1, so that the gas can pass by said valve to the gas manifold 38, but when themotor begins to attain a higher speed, the timer shaft 11 on which the governor 2O is mounted will cause the weights 20 to be 27 and the lower end of the rocker arm 32,
that a bend is forced in said spring. Therefore, as ythe lever 27 is slightly drawn downwardly during the travel of the cross head 23 as 'ust described, said spring 30 will be somew at straightened, and at the same time a force will bev given to said spring from the lever 27 in ai direction towards which the upper end of said lever is moving, andas soon 4as the leaf spring 30 isstraightened, the
force applied` thereto from said lever27 will i force the upper end of said. leaf spring over center, the movement of said-leaf spring being instantaneous and positive as'rregards its throwing movement. This vaction of the lever 27 on the leaf spring 30 will instantly throw the butterfly valve 35 to a closed posltion, as shown by dotted lines B, Fig.-1,
thereby cutting oil the full force of gaseous liuid ythat was heretofore being fed to the motor, in which instance the motor' cannot attain a higherspeed.
. 39. As soonjas thev s In order to prevent a complete shutting o5 of the gas supply, the'butterfiy valve 35 is perforated with a plurality of openings peed'of the'motor has been .checked as .just related, it is obvious thatif the speed of the motorlowe'rs, the
governor weights 20'L will be m'oved in wardly by the arms 19thereof, thereby mov,
ing the sleeve 14 back to its normal position,
"and instantl returning the lever 27 toits position, an the leaf spring 30 therewith, and throwing the valve 35 to 'its normal position, in which case the full force of fuel can be again fed to the motor.
After the valve 35 has lbeen operated to a closed position relative to'the speed of the motor, thel perforations 39 formed in said valve will allow enough fuel topass there- 'through so that the motorv can maintainthe speed attained when the valve was operatedl toa closed position, but it is self evident that a higher speedof the motor cannot be attained relative'to a pulling. load after the valve has been moved to its cut-off osition. In a device of this character, it as been `found that it is essential to quickly o en and close the valve 35, and not operate t e same slowly towards or away from a closed osition, as it is often necessary in hill clim in to give the motor a full volume of fuel, an if a slow operating device were used in connection with the motor. speed, the fuel supply will become less as the device is operated towards closing, whereas with this improved device, the cut-off mechanism will not operate towards closing, only when a maximum engine speed has been attained, in which instance an ample supply.v of fuel` can be fed unchecked `to the motor relative to hill climbin efforts, and the like.
For t e mountin vfof the butterfly valve 35 to the shaft'33, te shaft is split vas designated at 40, in which case the valve 1s being mounted in place before the pi e 34' Iis secured to the manifold 38, in whic the shaft is rst mounted throu h the openin 42 formed in the pipe 34, anfgl the inner en of said 'shaft engaged in the enclosed bearing 43 which is also formed` in the pi e 34.
The, butterfly valve is then introduce into the pipe 34 from the engaged in the split aft 33', and then se- .10o mounted in the split of the shaft, and is held` y iio upper end thereofand d i s 116 i cured in place by the pins 41;' the manifold 38 is then secured to the ipe 34. This manner of mounting the va ve to the shaft 33 will prevent the shaft from being withdrawn from its bearings, thereby preventing the valve from being' tampered-with. L i l .1
