Specification of Letters Patent.

Application filed March 22, 1912. Serial No. 685,604.
To all whom 2'25 may concern:
Be itknown that 1, Lotus Horne, a citizen of the United States, residing at Donn, in the county of Lyon and State of Iowa, have invented certain new and useful-linprovements in Gasolene-Engines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. 6'
This invention relates to internal combustion engines, such as gasolene engines; and it consists in the novel construction and combination of the parts hereinafter fully described and claimed whereby the inlet valve is held-closed by spring pressure when the exhaust valve is held open to permit the engine to run inactive, which is oecasionally desirable. lVhen running in this manner the engine piston is reciprocated by theenergy stored in the fly-wheel, and no power is developed in the cylinder, which is empty, the supply of fuel being cut oil by the speed governor.
In the drawings, Figure l is a sectional plan view of a portion of the cylinder of a 'gasolene engine provided with a springcontrolled lever for holding the inlet valve closed according to this invention. Fig. 2 is a side view of the lever and its supporting bracket.
The power cylinder 2 of the gasolene engine is provided with an exhaust valve 3 having a spring 4 arranged around its stem 5, and adapted to closethe valve. The inlet valve 6 has a stem 7, and a spring 8 which normally closes the valve and which permits it to open automatically at intervals, to supply the cylinder with a charge of combustible fluid. The spring 8 is ar ranged in a spring chamber 9, between the end of the cylinder and a collar 10 secured on the end portion of the stem. 7. The chamber 9' has a slot 11 in one side ofit. A longitudinally slidable valve rod 14: is
provided, and this rod works back and forth in a guide 15 under the control of a speed' governor of any approved make. The rear end of the rod 14 is pivoted by a pinlG to one end of a lever 17. This lever is pivoted ly a pin 18 to the chamber 9, and its other end is arranged in operative connection with the stem 5 of the exhaust valve.
lVhen the rod l t is moved rearwardly, and is held by the governor in that position, the exhaust valve is held open, so that the engine runs empty until its speed is reduced suliiciently to cause the governor to release the rod 14. Any approved detent mechanism may be used for holding the exhaust valve open, such as a pivoted pawl 30 carried by the engine frame and controlled by the speed governor, and engaging-with a stop 31 on the rod 14. When the engine is running empty in this manner it is desirable that no combustible fluid be wasted by being drawn through the inlet valve, and the rod- 14 is provided with abell-crank lever 20 for holding the inlet valve closed when the exhaust valve is held open. The long arm of this lever is arranged to project through the slot 11 and come in contact with the collar 10.
.The bell-crank lever is pivoted by a pin 21 to a bracket 22, 'which bracket is secured to the rod ll by one or more bolts 23. This bracket has a slot 24: for the bolt 23, which permits it tobe adjusted longitudinally of the rod 14. The short arm 25 of the bell-crank lever forms a stop which bears 011 the 'rod 14 to the rear of the pivot 21, and 26 is a spring arranged between the rod 14: and the long arm of the bell-crank lever to hold the long arm of the lever at substantially a right angle to the rod.
lVhen the exhaust valve is opened by the rod 14, the long arm of the bellcrank lever engages with the collar on the stem of the inlet valve, and prevents the inlet valve from opening. The spring 26 enables the bell-crank lever to hold the inlet valve closed irrespective of the exact amount of the opening of the exhaust-valve, and prevents in ury to the various moving parts.
The'bell-crank lever is adjusted to close the inlet valve at the most advantageous moment by adjusting the position of the bracket 22 on the valve-rod.
What I claim is:
1. In an internal combustion engine, the combination, with a cylinder provided with an exhaust valve and a spring-controlled inlet valve, of a longitudinally slidable valverod, .a pivoted lever connecting the said rod with the exhaust valve, a lever pivoted to the valve-rod and-operating to hold the inlet valve closed when the exhaust valve is held open by the valve-rod, and a spring secured between the valve-rod and the last said lever so that the inlet valve is held closed by spring pressure.
2. In an internal combustion engine, the combination, With a cylinder provided with an exhaust valve and a spring-controlled inlet valve, of a longitudinally slidable valverod, a pivoted lever connecting the said rod With the exhaust valve, a bell-crank lever pivoted to the valve-rod one arm of the hell-crank lever being arranged to hold the inlet valve closed When the exhaust valve is held open by the valve-rod, and its other arm being arranged to operate as a stop, and
a spring arranged between the bell-crank lever and the said valve-rod and normally. holding the said stop against the said rod so that the inlet valve is held closed by '15 sprlng pressure. In testimony whereof Iv have affixed my signature in the presence of two witnesses.
