'Application led .Tune 16, 1924, Serial No, 720,414, and in Great Britain' September 28, 1923.
" This invention relates to internal combus- The primary object of the present lnven tion is to overcome this diiiculty by so arranging the engine as to allow of the ready inspection and removal of parts.
More specific objects of the invention are (1) to arrange that the auxiliary engine elements, such for example as the engine governor and the water, oil and fuel pumps, and the gearing necessary for driving these elements are readily detachable from the engine# 2) to provide means whereby the pistons and their connecting rods can be easily inspected or removed;
(3) to arrange for the inspection of a cyl- .inderhead 'and the valve gear and vother parts associated therewith without disturbing the other cylinders.
Further objects of the invention will be apparent from the'following description of the accompanying drawings, which show a preferred arrangement according to the invention as applied to a multicylinder internal combustion engine. In these drawings,
Figure 1 is a side elevation of the engine.
Figure 2 is an end elevation thereof show- 40 ing the detachable gear frame,
Figure 3 is an enlarged view partly in sectioi of the left-hand fportion of Figure 1; an
Figure 4 is an elevational view of the detachable gear frame, showing the vgears in position therein.
In these drawings the cylinders are ar# ranged in line and theengine casing` A is provided with doors B in the side walls, these doors being made large enough to allow .of the removal of a piston and its connecting rod and also serving for inspection purposes -or for the'adistmentof the bearings .an bearing surfaces. A door isprovided only on one side 'of the casing opposite each crank so that the strength of the walls will not be materially reduced and there will becontinuous metal on one side of each vcrank throw.
In order not to weaken one side wall of the A is bolted to one, end thereof, and supports all the gearing necessary for the transmission of the drive from the -crankl shaftl D to the cam shaft E and to a number of auxiliary engine elements carried'on'the frame. The frame ishpreferably in the form of'a box or casing which encloses as well as supports the gearing, This arrangement allows of the complete removal of the frame C together with the gearing and auxiliary elements for inspection; or renewal ofparts or for the substitution of a new framc.
The gearing box orframe' C contains a gear wheell F mounted on the end of the crank shaft D, which is internally splined to engagewith a detachable extension D of the shaft D` this extension being utilized'to Vdrive the fuel pump G. The gear wheel F meshes on one side with a gear Wheel F which in turn meshes with another gear wheel F2. This wheel F2 is utilized to drive the lubricating oil pump H. 0n its other side the gear wheel F drives through a train of gearing F3 F4 F5 F6 F" another gear wheel Fs which is mounted on a sleeve surrounding the splined end of the cam shaft E. Thegear wheel F8 also meshes with another .gear wheel F by means of which the cooling water pump J isdriven. *The gear'wheels' F1, F?.v F3. F4, F, F", F7, and'F", are all supported by the frame C as shown 1n Figure 4. The gear wheels' F, and F8' being carried respectively by the crankshaft D, and by the camshaft E..
In the construction illustrated the frame C carries the lubricating oil Vpump H. lubricat-ing oil filters H. the -fuel pump G, fuel oil filters G', the cooling water pump J, and the governor K. butY it will be understood that other auxiliary engine elements (such for example as a magneto lor magnetos, a mixture distributor for starting purposes` a d revolution indicator or the operating mechanism therefor, etc.) maybe carried on the frame either in addition to or instead of these elements. Any or all of such elements may driven directly from one or other `What vIclaim as mv invention and desire ernor, oil or water pump, magneto and the of the gear wheels vF F F9 or from other gear wheels connected thereto.
. The various connections from these elements to other' parts of the engine may be made externally or may pass through the box into the engine casing, suitable joints `being provided to allow of the-removal of .the whole frame C together with the members carried thereon, when desired.
The housing E for the cam shaft E is made integral with the engine` casing A and is provided with a number of openings E2 (normally .covered by a cover plate E3) through which pass the various tappet rods or the like for operating the valves in the.
cylinder heads. o
The-cylinders also have separate detach-v able cylinder covers L, so that any cylinder vhead may be linspected or repaired without disturbing the other parts of the engine.
AIt will be understood that this construction has been described by way ofexample only and thatl modifications may be made without departing from the scope of the invention.`
'the end of the engine casing, a train of intermeshing gear wheels having their axes parallel, to the axis of said crankshaft and v camshaft. spindles .for the gear wheels, bearings for the spindles carried by the frame so' that the gear wheels are carried by and removable with the frame, said gear wheels serving to connect the `crankshaft to the camshaft, and auxiliary devices such` as govlike, one at least of which is carried upon the frame and driven from the spindle of one of the intermeshing gear wheels, said casing with all parts carried thereby being immediately removable when unbolted from the engine casing.
V2. In an internal combustion engine, in combination, an engine casing, acrankshaft rotatably mounted in the casing, a camshaft rotatably mounted in the casing but at some ldistance from said crankshaft, a frame detachably mounted on the end of the. casing, a train of intermeshing gear wheels having their axes parallel to the axis of said crankshaft, spindles for the gear wheels, bearings for the spindles carried by the frame so that.
the gear wheels are carried by and removable with the4 frame, said `gear wheels serving to connect the crankshaft to the camshaft,
ing with all parts and a vplurality of engine auxiliary devices driven from said spindles, one at least of said devices being carried upon the frame so as to be removable therewith, said casing with all parts carried thereby being immediately removable when .unbolted from the' engine casing.
3. In 'an lnternal combustion engine, in comblnatlon, an engine casing, a crankshaft rotatably mounted in the casing, a camshaft l rotatably mounted inthe casing, said crankshaft and camshaft having ends projecting beyond the end of the casing, gears secured.
to the projecting ends of said shafts, a frame detachably mounted on the end ofthe casing,
a train of intermeshing gear wheels connecting `the gear wheels on said shafts and having their axes parallel `to the axis of said crankshaft, spindles for thel gear wheels, bearings for the spindles carried by the fra-me so .that the gear wheels are carried by and removable withA the frame, and a plurality of engine auxiliary devices drivenfrom said spindles, one at least of said devices being carried upon the frame so as to be removable therewith, said casing with all parts carried thereby being immediately removable when unbolted from the engine 'l Y casing.
4. In combination, an engine casing, a crankshaft rotatably mounted in the casing, a camshaft rotatably mounted in the casing` said crankshaft and camshaft havingends projectingbeyond the end of the casing, gears secured to the projecting ends of said shafts,.a frame detachably mounted on the end of the casing, 'a train of intermeshing gear wheels.
connecting the gear wheels on-.said shafts and having their axes parallel to the axis of said crankshaft, spindles for the gear wheels, -and bearings for the spindles carried by the frame so that the gear wheels are carried by and removable. with the frame, said cascarried thereby being immediately removable when engine casing.
5. A n internal combustion engine including in combination. a plurality of engine cylinders, pistons reciprocating therein. a connecting rod for each piston, a crank shaft on which the connecting rods act, an ,engine casing enclosing the cylinders and the parts cooperating therewith, and a door disposed andof such'a size as to permit the inspecan internal combustion engine, -in
unbolted from the tion and removal of a piston and its conl l necting rod, the inspection doors for adjacent cranks being on opposite sides of the engine casing as set forth.
In testimony whereof I vhave signedmy name to this specification. i
