Specification of Letters Patent.
Patented Aug. 12, 1919.
Application filed November 12, 1915. Serial No. 61,066.
One of the objects of the invention is to provide a hydrocarbon motor of high power.
with a suitable propeller driving mechanism associated therewith.
Another object of the invention is to provide a hydrocarbon motor with a propeller driving mechanism and a cam shaft driving mechanism.
Another object of the invention is to provide a hydrocarbon motor with suitable bearings within the crank case of the motor for carrying the driving shaft of an aeroplane propeller.
Other objects of the invention will appear from the following description, taken in connection with the drawings which forms a part of this specification, and in which-- Figure 1 is a vertical longitudinal section through a motor embodying, this invention;
Fig. 2 is a transverse vertical section through the motor shown in Fig. 1; and
Fig. 3 is a plan view of part of the motor shown in Figs. 1 and 2.
Referring to the drawings, 10 represents the upper half and 11 the lower half of the motor crank case or base, between which halves are the bearings 12 for the crank shaft 13. At one end of the motor, the crank shaft extends through the crank case, and on its projecting end 14 is mounted a fly-whel 15.
The lower half 11 of the crank case forms an oil well, which is provided with an oil screen 16 extending entirely across the well. The oiling system may be completed by the use of a suitable pump and conduit to carry the oil from the well. below the screen 16 to the various hearings to be lubricated.
The form of motor shown is of the V- type, the cylinder blocks 17 being mounted as shown particularly in Fig. 2, upon the upper. half 10 of the crank case. Suitable cognscting rods 18 and pistons 1.9 are provi 2 Extending along the heads of the motor c 'lindcrs are cam shafts 20, one for each side of the motor, and suitable cams are arranged on these shafts for operating the intake and exhaust valves 21 and 22 respectively. Rockarms 23 are included in the valve operating mechanism, and suitable intake and exhaust pipes 24 and 25 supply the gases to and exhaust them from the motor cylinders. A carbureter 26 supplies the in take conduits.
The end of the motor crank shaft 13 opposite to that upon which the. flywheel 15 is molmted, is provided with a gear or sprocket 27 which may be connected to drive the various auxiliary mechanisms of the motor, such as the pump, generator, etc.
The motor herein illustrated is particularly adapted for aeroplane work, and it is provided with a heavy driving shaft 29, which is connected direct] to drive a propeller 30, which is securely keyed to the driving shaft at the end of the motor opposite to that where the Fly-wheel 15 is mounted. For the purpose of procuring steadiness in the drive, and reducing torsion on the crank shaft to a minimum, gearing for driving the shaft 29 from the crank shaft is provided at the end of the motor adjacent the fly-wheel l5. As shown. this gearing consists of a pair of spur or vsimilar gears 31 and 32, the former being secured to the crank shaft and the latter to the driving shaft 29.
The driving shaft 29 is shown as mounted in bearings 33 in the upper part of the crank case upper half 10, these hearings being exposed to the interior of the crankcase so that they will be lubricated by the splash therein or may be fed by conduits in the lubricating system and the overflow of oil drained back into the crank case. Thus is obtained a rigid and secure mounting for these bearings 33, and the driving shaft 29 is maintained in correct alinement in its parallel and offset relation to the crank shaft.
The upper halves of the bearings 33 are retained in place by a cover 34, which extends the length of the motor crank case and closes an opening in its upper wall, between the bases of the cylinder blocks 17. This over is secured in place by bolts, and by removing it, the entire driving shaft 29 may be lifted out.
The drive for the cam shafts 20 at the heads of the motor cylinders is taken from the driving shaft 29. A suitable worm gear 35 is mounted at about the middle of the driving shaft 29, and a shaft 36 for each side of the motor carries the drive to the cam shafts through gears 37 and 38 at the respective ends of the shafts 36. The lower ends df the shafts 36 extend into the crank case as shown particularly in Fig. 2, where they receive ample lubrication, and their upper ends and the gears 38 on those ends are housed within a casing 39, which is suitably secured to the upper ends of the cylinders.
While one form only of the invention has been shown and described it will be understood that the invention is not limited to this form, as it will be apparent that changes may be made without departing from the spirit or scope of the invention as set forth in the accompanying claims.
Having thus described my invention, what- I claim and desire to secure by Letters Patent is:--
1. The combination with a V-type motor having a crank shaft, of a fly wheel on said shaft at one end of the motor, a driving shaft arranged parallel to and in the same vertical plane with the crank shaft and above the latter, gearin from the crank shaft to the driving sha t at e fly wheel end of the motor and a prop ller on the drivin shaft at the other end of the motor.
2. Tie combination with a multi-cylinder V-type motor havin a crank shaft, of a driving shaft extendin the full length of the motor and arrangef parallel to and offset from the crank shaft and connected to be driven thereby, cam shafts extending alon the heads of the motor cylinders, gearing mm the driving shaft to said cam shafts, and a propeller mounted on the driving shaft.
3. The combination with a multi-cylinde-r V-type motor having a crank shaft, of a drivin shaft arranged parallel to an'd'ofl'set from 51c crank shaft, gearing at one end of the motor connecting the crank and driving shafts, a propeller mounted on the driving shaft at the other end of the motor, cam shafts, above the driving shaft and extending along the heads of the motor cylinders, and gearingfrom the driving shaft to the cam shafts intermediate the ends of the motor.
4. The combination with a V-type motor having a crank shaft, a flywheel at one end of said crank shaft, a gear sprocket at the other end of said crank shaft, a driving shaft parallel to said crank shaft and extending the length of the motor, gearin between said crank shaft and said driving shaft and a propeller at one end of said drivin shaft.
5. T e combination with a multi-cylinder motor havin a' crank shaft of a driving shaft paralle thereto and above the same in the same vertical plane therewith and extendin the full length of the'motor, a cam sha t'extendin along the heads of the motor and for the ull length of the latter and parallel to the first mentioned shaft, and gearing for transmitting motion from the crank shaft to the driving shaft and separate gearing for transmitting motion from the driving shaft to the cam shaft.
6. The combination with a V-type motor having a crank shaft, of a driving shaft extending the full length of the motor and arranged parallel to and offset from the crank shaft and connected to be driven thereby, cam shafts above said driving shaft and extending along the heads of the motor cylinders, a car at about the middle of said drivin s iaft and connection from said gear to boti said cam shafts for operating the same.
7. The combination with a- V-type motor havin a crank shaft, of a driving shaft arran e parallel to and above the crank sha t and in the same vertical plane therewith said driving shaft extending the full length of the motor through the upper art of the crank case, gearing at one end 0 the motor driving the driving shaft from the 5 crank shaft, cam shafts extending along the motor for the full length thereof above the driving shaft, a gear substantially midway of the driving shaft, connecting shafts between sa'id cam shafts and said driving shaft, and gears carried at the lower ends of said connecting shafts within the crank case for engaging said central driing shaft gear.
In testimony whereof I ailix my si nature.
GEORGE L. Mo AIN.
