Application led September 21, 1915. Serial No. 51,851.
To all 'whom/15 may concern:
Be it known that I, ROLLO R. BELL, a citizen of the United States, residing at Los Banos, in the county of Merced and State of California, have invented a new and useful Internal-Combustion Motor, of which the following is a specication.
The device forming the subjectV matter of this application is an internal combustion engine and the invention aims to provide novel means for admitting an explosive charge between a pair of pistons mounted to move in opposite directions, and to provide novel means for firing the charge and exhausting the same.
1t is within the province of the disclosure to improve generally and to enhance' the utility of devices of that type towhich the present invention appertains.
With the above and which will appear as the description proceeds, the invention resides in the combination and arrangementof parts and in the details of construction hereinafter described and claimed it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed, without-departing from the spirit of the invention.
1n the accompanying drawings Figures 1 and 2 are longitudinal sections embodying an internal combustion engine constructed in accordance with the present invention, the pistons being in different positions;
Fig. 8 is a vertical longitudinal section, the cutting plane being passed through the structure at right angles to the cutting planes in Figs. 1 and 2;
Fig. 4 is a side elevation of the engine.
1n the drawings, the numeral 1 has been employed to designate generally a crank case provided with guides 2. Journaled for rotation in the crank case l is a shaft 3 equipped with cranks 4 and 5.
The crank case 1 carries a cylinder 6 embodying a head 7, the cylinder being suitably water-jacketed as shown at 8. In the cylinder 6 adjacent its top municating with a supply pipe 10. Any
other objects in view 1s an inlet port 9 comsuitable means, such as a common shaft actuated puppet valve may be employed for controlling the port 9, this detail having been omitted from thedrawings because` it is well understood, and because, in general, an engine construction cannot be characterized patentably by any specific firing or charge controlling means. intermediate its ends, the cylinder 6 is supplied with one or more .spark plugs 11.V The cylinder 6 is provided, 1n its inner face and-adjacent its top with upright, longitudinal channels 12. Below the channels 12, the cylinder 6 is furnished with a lateral, annular inlet passage 14. Below the passage 14,- the cylinder 6 carries an annular exhaust passage 15 communicating withl an; exhaust pipe 16, the passage 15 opening `into the interior of the cylinder 6 as shown at 17.
Mounted to reciprocate in the cylinder 6 is an outer piston 18 provided with a firing port 2O adapted to coincide with the'spark plugs 11, the piston comprising a head 19. Adjacent its lower end, the outer piston 18 carries a shaft 21, a pitman 23 forming an operative connection between the shaft and the crank 4. In the outer face of the outer piston 18, longitudinal channels 23 are formed, the same terminating in spaced relation to the ends of the piston, the piston being provided with combined inlet and eX- haust ports 24.
Mounted to reciprocate-within the outer piston 18 is an inner piston 25 embodying a head 26, the innerpiston preferably comprising laterally separable` parts united by bolts or otherwise, as shown best at 27 in Fig. 3. 1n the inner piston 25 there is an elongated opening 28 in which the shaft 21 of the piston 18 isV adapted to move, said piston being provided at its lower end with a cross head 29 carrying shoes 30, adapted to coact with the guides 2, the shoes being adjustably secured to the cross head 29, as indicated at 31. A pitman 32 forms an operative connection between the cross head 29 and the crank 5.
The space between the head 19 of the outer piston andthe head 7 of the cylinder 6 'constitutes a compression chamber 33, the space Y between the head of the outer piston and the in the chamberand: has -flowed by way of the channels 12 in the cylinder andby way i Y Aof the channels 23 in the outery piston 18 into the, inletpassage 14;] lVhen the parts are thus arranged, the outlet ports 240i' the cylinder 18 are in registration with the open- 'Y ings 17,Y in the lexhaust passagesl. The
