Specification of Letters Patent.
w r v Wil is Tilt Application filed duly 2'2, 1908. Serial No. 45.5%.
To add w/iom at may concern.-
Be, it known that I, Jenn B. BAKTHOLO- MEW, a citizen of the United States, residing at Peoria, in the county of Peoria and State of Illinois, have invented certain new and useful Improvements in Lubricators, of which the following is a specification, referencc being had therein to the accompanying drawing.
This invention relates to the improved system of lubrication for engines, of the type shown in my application for patent Serial Number 320,798, filed June 8, 1906. As remarked in the aforesaid application, the system, while it may be said, in general, to be of the splash type, possesses certain added features not heretorfore employed in lubricating devices of the splashtype,
the object of said features being to obtain more perfect lubrication under certain'conditions of opreation, especially the conditions met with in the motor vehicle art.
The present invention relates more particularly to structural matters, having for its object the production of a simple, coinpact and generally eflicient structure.
The nature of the invention will be clearly understood from the following description, in connection with the drawings, in which I have shown the invention ap plied to a multiple cylinder internal combustion engine. of the sort employed to drive motor vehicles.
pending arms 7-7. The construct In the drawings, Figure 1 is a vertical, longitudinal section of a four-cylinder engine-embodying my improvements, the sec tion being taken on the line a;m of Fig. l, and some of the parts being shown in elevation. Fig. 2 is a sectional elevation of the right end of said engine, the section being taken on the liue y of Fig. 4. Fig. 3 is a transverse vertical section, taken on the line e-2 of Fig.1. Fig. l is a plan view ries of overflow ducts or ports 13, which i are disposed at the level at which it is desired to maintain the oil in the bottom of the crank chamber. The bottom parU of the crank chamber is divided into a number of compartments, preferably one for each of the cranks, by means of transverse ribs 14. Thus the oil is prevented from flowing freely from end to end of the crank case, when it is tipped, as, for (trample, when the vehicle is going up or down a grade.
At one end the lower part 3 of the crank case is provided with an' extension 15 designed to inclose a pump 16 and the devices for operating the said pump. The pump 16, as shown, is of the rotary gear type caving an upstanding driving shaft or swindle 17 to which is loosely or detachably coupled a depending shaft 18 which carries a gear 19 meshing with and driven by a companionv gear 20, on the crank shaft- 4. The. shaft 18 is supported in a bearing 21 carried by the crank case. The upper part 2 of the crank case is formed with an extension 22 which in connection with the extension 15 of the lower part of the case incloses the gearing 19-20. The bottom or floor of the chamber, formed by theextension 15, is preferably upon the same level, or is at least as low as the lowest part of the floor of the chamber or compartment 12," and the pump 16 is mounted with its suction or supply passage 23 close to the bottom or floor of the extension 15, so as to insure a supply of oil to the pump at all times. The tube 9dr leads from the discharge passage of the pump up- Ward into the crank chamber, and extends horizontally adjacent the wall of the chamr, as is clearly shown in Figs. 1 and 3.
-The horizontal part of the tube is provided with discharge ports 24, of which there are one or more for each of the compartments formed by the transverse ribs 14.
I prefer to provide means for indicating the oil level and employ for this purpose a glass tube 25, which is connected by means The crank case being to the overflow passages 13, and the recepa of suitable'iittings 26 with the lower part of the chamber extension 15, asis clearly shown in Fig. 2. 'lhe'sight tube is pro erate under the con 'tions, met with inmotor vehicle practice.
fined with on up tacl oiucoinpartment 12 being also filled with oil, the '0 eration of the pump serves to lift the oil rom' compartment 12, forces it through the tube 24 and through thedischarge apertures of the latter into the crank case. It, will be understood that the oil may flow gently through the apertures, or
may be discharged in the form of jets, ac-
cordnig to the'spee'd of the pump, which,
of course, will be determined by the ratio of the gears which drive the pump. In
. either case the oilis distributed throu bout the length of the crank case'and fin its way into the several compartments formed by the transverse ribs or webs 1a. The surplus oil is drawn oil from theseveral conipartments through the overflow passages 13, into the compartment 12, as rapidly as it accmnirlatss,and thus the oil is maintained at the desired level' in the said compartments; Into the severalbodies of oil thus maintained, the cranks and connecting rods dip asthc shaft turns 5 lashing and churning the oil-in the wel known manner so as to lubricatethe piston, cylinder and. hear-- ing connections between the pistons and connecting rods, .as well as all of the .crank shaft bearings. If the engine be considerably inclined by tipping about a transverse axis a's in passing up or down hill, it is clear that the transverse .webs will prevent the oil from running freely to the lower end of the crank case, so as to deluge the lowermost crank pins, while leaving thbse at the upper end of the crank case practically dry, the injurious effects of leaving the bearing parts of one-or'more of the cylinders dry is obvious, and it is also well understood by those familiar with this cart that a surplus oi? lubricant IBSllltS in the fduling of the cylinders and ignition devices.-
It is clear that the engine constructed, as. :ibove described, although possessing the desirable features of lubrication of the engine shown and described in my prior application above referred to, is entirely self-- .contained'and is scarcely greater in bulk than the ordinary en ine' having a pla n crank case. Thenum er of parts also 1s reduced to a minimum. I
Havin thus described my invention, what I c aim is:
1. In a luhricator for an internal coinbustion engine, the combination of a crank.
case having formed withinit and inclosed by the outer walls thereof a main oil reservoir, a crank-chamber above the reservoir and adapted for holding a limited amount of oil, a duct for leading the overflow of oil from the crank chamber back to the reservoir, and a pump within the crank case, the walls of'the' crankcase on all sides of the pump ext'ending to points above the level of the oil in the reservoir.
2. In a lubricator for an internal combustion engine,the combination with a crank case having formed within it and inclosed by the outer wallsthereof a main oil reservoir, a crank chaniber'above the, reservoir and adapted for holding a limited amount of oil, a duct for leading the overflow of oil from the crank chamber back to the reservoir, of
a pump within the crank case, the walls of the crank case extendin upward to points above the oil level in t e reservoir, and a pump driving mechanism arranged on lines within the crank case and extendin from the pump to points above the oil levein the reservoir, wherebyleakage of oil to points exterior to the crank case is prevented.
