Application filed May3, 1918. Serial No. 232,364;

T 0 all whom it may concern:

Be it known that I, CLA ENCE R. EATON, a citizen of the United States, residing at Goldwater, in the county of Comanche and State of Kansas, have invented certain new and useful Improvements in Engines, of which the following is a specification.

This invention relates to internal combustion engines, and more particularly to an engine provided with a mechanism for supplying lubricant to the bearing surfaces.

One of the main objects of the invention is to provide an internal combustion engine of comparatively simple construction provided with simple and efficient means for supplying lubricant to the bearing surfaces. A further object is to provide a lubricating unit so mounted as to permit removal of the lower section of the crank casing with out necessitating demounting or disassembling of the lubricating means. A-further' object is to provide-trough-like members in combination with dripping elements or ladles carried by the connecting rods of the pistons operative in the trough members for dipping oil therefrom when the connecting rods are reciprocated, means being provided for supplying lubricant to the troughs. Another object is to provide a pump of simple construction and operation which is so associated with the lubricating unit as to be readily detachable, when necessary. Further objects will appear from the detailed description.

This base is provided with suitably spaced openings in which are secured the lower ends of" the cylinders 2. Each of these cylinders is provided with an outer water jacket 3 and a cylinder head 41 secured thereon by means of bolts 5, this head being provided with inlet and exhaust openings controlled by the valves 6 and 7, respectively. These valves are held in raised position, normally,

the valve stems and confined between the engine head and disks 9 secured on the valve stems adjacent the upper ends thereof.

A radiator 10 of any suitable. constructionis connected by means of a pipe 11 to the water space of the front cylinder adjacent the lower end of'the water jacket 3, r I

the upper end or top of the radiator being connected by a pipe 21, to the cylinder at the upper end of the water space. The water spaces of the two cylinders are connected by means of the tubularmembers 13 each provided with a union 14 so as to permit the cylinders to be independently detached from base 1. Each cylinder is further provided, adjacent its lower end, with an outer annular flange 15 which is pro- 7 vided with a plurality of spaced apertures to receive securing screws 16 which are threaded into the base lthus detachably securing the cylinders to the base. By re,- moving these securing screws, the cylinders may be independently removed from the engine base so as to permit ready access to the interior of the cylinders and to the inv terior of the engine base and crank casing carried thereby. I11 this manner, either one be readily reposes.

A. piston 17 is operative in eachcylinder andisconnected by a connecting rod 18, to

acrank shaft19 rotatably supported in, the' base 1. The lower plate 20 of thebearing sleeve of the connecting-rod. 18 is provided with a downwardly directed substantially triangular dipper21 the apex of which is directed downwardly. This dipper is in yer ticalalinement with anyarcuatextrough 22 V which is of substantiallysemi-circular shape,

When the engine is in operation, the dippers 21 will be lowered into the trough 22 and moved through the same, these clippers being then raised out of the trough and moved in a reverse direction so as to discharge the oil or.other lubricant contained thereby.

Each of the troughs 22 is provided, at its lowermost point, with an opening which receives a nipple 23 carried by a T 24 which is interposed in an oil pipe 25. This oil pipe communicates at its lower end with the main bearing indicated generally by 26 of the main crankshaft 19. At its inner end, the pipe 25 communicates with a T connection 27 which is threaded onto the lower end of the cylindrical discharge spout 28 of an oil pump 29. Oil is supplied by this pump to the trough 22 and to the main bearings 26, when the pump is operated, so as to iii-- sure proper lubrication of the bearing. The body of pump 29 is divided by a central web 30 into an intake chamber 31 and an exhaust chamber 32. The lower end of the intake chamber 31 tapers downwardly to provide a seat for a ball valve 33 mounted therein which controls the intake opening 34. Upward movement of this valve is positively limited by arod 35 which extends across the lower portion of the intake chamber above the valve. A suitable screen 36 is screwed onto the lower end of the intake chamber and, when the pump is in operative position, this screen projects into-an oil well formed inthe crank casing 38. An upwardly projecting wall 39 is formed inthe intake chamber 32,'this wall serving with web 30 to provide a valve chamrod 41 similar to rod 35.

her which receives the ball valve 40 for controlling "communication between the intake and exhaust chambers, upward movement of this valve being positively limited by a A piston 42 is operative in the barrel 43 of the pump, this piston being connected by a piston rod 44' to an eccentric disk 45 keyed on a cam shaft 46 rotatably supported in the base 1. The

eccentric'disk 45 is provided with a central peripheral groove which forms lateral retaining flanges between whichis mounted a connecting strap or collar 47 which serves to loosely connect the upper end of the piston rod- 44 to the disk in the well known manner. .A spur gear 48 is keyed on cam shaft 46 and'meshes with a similar gear 49 keyed on the crank shaft '19. In this manner, when the crank shaft is rotated, the

cam shaft will be rotated so as to reciprocate'the piston of the pumpthus drawing oil into the intake chamber 31' and forcing this oil into and through the exhaust chamber 32-to the main bearingof the crank shaft and to the trough 22. To permit removal of the gear 49, one crank 50 of the crank shaft 19 is detachably secured to the body .disposedlaterally of the utilized for d iving a b lt pulle when" it is' portion of the shaft, as will be clear from Fig. l of the drawings The pump 29 is supported by a bracket 51 which is shaped to fit about one side and the top of the pump, the upper end of this bracket being bifurcated to fit aboutt-he lateral faces of a bearing beam 52 extending transversely of the base 1, this beam being provided with lateral recesses to receive the arms at the upper end of'the bracket. 7 This bracket is detachably secured to the beam by securing bolts inserted through the arms of the bracket and threaded into the beam, and the pump is similarly secured to the bracket so as to be detachable therefrom. The pump and the parts associated therewith constituting the lubricating unit are thus all supported by the base 1 so that the lower sec tion of the crank casing 88 may be removed without disturbing the lubricating unit thus permitting ready access to the same. The central bearing for the main crank shaft will be thoroughly lubricated by the oil which is splashed thereon during the operation of the engine due to the action of the dippers 21 in thetroughs 22.

Cam shaft 46 is provided with a plurality of cams 53 secured thereon which engage the lower ends of operating rods or plungers 54 which are reciprocably mounted in the upper section of the crank casing, a rod 55 being adj ustably secured to member 54 at its lower end, this rod being operated through a bracket 56 projecting from the engine head 4. The upper end of rod 55 is of rounded or substantially spherical shape and is operative in a corresponding recess in the outer end of a rocker arm 57 which is rockably mounted for movement about a horizontal axis in a supporting frame 58 formed by an extension of one of the securing bolts 5. The inner end of rocker arm 57 engages the upper end of the valve stem so as to depress the valve when the outer end of the arm is raised, the valves being depressed andraised in succession so as to admit'an explosive mixture to the cylinders, and permit the products of'combustion to be expelled'there- 60 is secured on the forwardcml-of stub shaft 62 secured on the fan shaft 63 rotatably supported in the fan bracket 64 secured to the casing l adjacent the front thereof. A fan 65 of suitable construction is secured on shaft 63. In this manner, rotation is .im-

parted to the fan direct from the crank shaft. A bevel gear 66 is secured on'stub. shaft 59 and meshes with a similar gear 67 shaft whichmay be posed beneath said desired to use the engine for belt work, or for any similar purpose desired. Crank shaft 19 is provided, at its other end with a substantially disk shaped head 66 to which is secured the fly wheel 67. Fly wheel 67 is provided, in its outer face, with a substantially frusto-conical recess indicated by 68 adapted to receive a clutch cone for operatively connecting the crank shaft to a transmission shaft.

As will be noted more clearly from Fig. 2 of the drawings, the end portions of the cam shaft 16 are rotatably supported by bearing members 69 and 70 mounted in the base section 1 of the casing. The bearing portion of shaft 46, at each end thereof, is provided with oppositely directed helical grooves 71, which cross and extend inwardly from collars 72 secured to the shaft adjacent the inner end of the bearing member. The inner ends of these grooves 71 terminate closely adjacent concave oil receiving members or cups 73 which are secured to the shaft 4L6 and project substantially radially therefrom. These members are adapted to receive oil which is projected thereon during the operation of the crank shaft, this oil being directed into the grooves 71 by means of which it is conducted onto the bearing surfaces of the end portions of the shaft. This insures proper lubrication of the bearing portions of the shaft so as to prevent looseness or excessive wear thereof.

To permit access to the gears 48 and 49, I provide a gear housing 7 3 which is detachably secured to the upper section 1 of the casing, thishousing being in alinement with the gears. By removing housing 7 3, ready access to the gears is obtained as will be evident.

The foregoing description and the drawings have reference to what may be considered the preferred, or approved, form of my invention. It is to be understood that I may make such changes in construction and arrangement and combination of parts, ma terials, dimensions, etc., as may prove expedient and fall within the scope of the appended claims.

llaving thus fully described my 111V611 tion, what I claim as new and desire to secure by Letters Patent, is:
