This invention relates to devicesfor feeding liquid lubricant to the upper cylinder parts and valve stems of internal combustion engines and is particularly adapted for use in connection with the internal combustion engines of motor 'vehicles.
Numerous devices have been placed on the market and others have been disclosed in patents having for their purpose the obtaining of what is known as upper cylinder and valve lubrication vfor the internal combustion engines of motor vehicles.
The oil delivery In most of these prior devices varies in accordance with variations in pressure within the intake manifold of the engine and because of this, it is extremely diilicult to adjust such devices so as not to overfeed oil during idling of the engine and still obtain sufficient oil during periods when the control valve of the carbureter is open any'substantial amount.
We have found that if a suitable grade of oil for upper cylinder and valve lubrication is fed into the fuel line between the fuel tank and the fuel pump or into the carbureter iloat chamber in properly adjusted quantities for average operation ofthe engine, satisfactory upper cylinder and valve lubrication can be obtained, and an object of this invention is to produce a simple, easily regulated device for delivering by gravity a drop by drop feed of lubricating oil to the fuel line of the internal combustion engine of a motor' vehicle at some point in advance oi' the point at which the liquid fuel is picked up by the air traversing the carbureter.
Another object isto provide. a device such as above; outlined which is automatic in its operation,r that is in which the feed of lubricating oil starts either when the ignition switch is closed or when the battery charging generator starts to deliver current and in which the feed stops when the ignition switch is opened or when the battery charging generator stops delivering current.
These,v as well as other objects, which will read- 45 ily appear to those skilled in this particular art, we obt'ain by means of the device described in the specification and illustrated in the drawing accompanying and forming part of this application and inr which similar elements are denoted 50 by like characters.
In the drawingz- Figure l is a view in sectional elevation of the oil feeding device of our invention; and
Fig. 2 is a diagrammatic illustration disclosing one manner of connecting up the device of Fig. 1.
The device of our invention comprises a reservoir for holding a supply of lubricating oll, a needle valve for controlling the drop by drop gravity feed of oil from the reservoir, a window or sight feed glass for visibly indicating and determining the desired drop by drop feed of oil. a valve chamber below the window or sight feed glass and provided with an outlet orice in its bottom surrounded by a seat for a steel ball for normally closing the valve chamber outlet, an electromagnet having its coil connected either in series with the ignition coil of the engine, in connection with which the device is used and having one end of its core extending into thevalve y chamber in line with said ball, tubing for connecting the device to the fuel line on the inlet side of the fuel pump or to the carbureter float chamber and means for venting the system to the atmosphere at a point adjacent the valve chamber outlet and below the ball controlling saidx outlet.
'Ihe reservoir is preferably made of a size to hold a liberal supply of oil and has a base mem- -ber 3 provided with an upstanding centrally located tubular member 4, a top member and a glass cylinder 6. Soft annular gaskets 'l preferably formed of cork are positioned between the top and bottom of the glass cylinder and the topand bottom members 3 and 5 respectively. The bottom member is provided with an upstanding annular flange 8 which surrounds the bottom of the cylinder 6, While the top member 5 is provided with a depending annular ange 9 which surrounds the top of the cylinder. Central tubular member 4 has its upper outer portion threaded and an internally threaded nut Ill securely clamps the assembly into a rigid structure.
Base member 3 at its center is provided with a depending circular boss II and depending fromthe center of this is a discharge nozzle I2.
A tapered valve seat I3 is formed at the junction of the internal bore of tubular member 4 and the central bore of nozzle I2. A pin I4 having its lower end coned as shown-at I5 has its upper en'd enlarged and threaded as shown at I 6 for threaded engagement with the bore of the upper reduced portion I1 of clamping nut I0. Pin I4 at its top is provided with a knurled head I8 by means of which the valve may be adjusted.
The interior of the reservoir by means of a duct I9 drilled through a wall'of tubular member E near its bottom is placed in communication with the interior bore of tubular member 4 and it will be apparent that the dropby drop gravity feed of oil from the reservoir may be controlled by means of the needle valve comprising seat I3 and the coned end I5 of pin I4.
A tubular sight glass 2l) is held in position below nozzle I2 by means of a more or less cylindrically formed housing 2|. The upper end of this housing is threaded onto central boss II of bottom member 3 and is provided with oppositely positioned circular windows or openings electromagnet.
one of which is shown dotted at 22 so that the drop by drop gravity discharge from nozzle I2 may be seen and the needle valve adjusted to obtairi the feed desired. y
"A valve housing 24 threaded onto a depending boss 26 of housing member 2| forms a valve vchamber 26 which communicates with the interior of the sight glass by means of a duct 21.
Valve chamber 26 is provided with a centrally located outlet port 28l and the oor of the chamber surrounding the outlet 28 is coned as shown at 29 to form a valve seat for a steel ball 30.
Valve housing 24 is preferably formed of brass or some other non-magnetic material arid one side wall thereof is drilled and tapped to receive the threaded end 3| of the core 32 of an The inner end of this core Within valve chamber 26 is provided with a contact member 33 formed of brass or some other non-magnetic material. The electromagnet carries -a suitable winding 34 one side of which is adapted to be grounded as shown at 35 Figure 2 ,while the other side is adapted to be connected to the primary side 36 of the ignition coil 31 of the motor vehicle, so that as the ignition switch 38 is closed, the electromagnet will be energized and ball 30 rocked from its seat as shown in Fig. 1 (the normal position of the ball is shown by dotted lines) and the oil within valvechamber 26 allowed to flow through valve chamber outlet 28.
Thevvalve chamber housing by means of a suitable fitting 39 is adapted to be connected by suitable piping 40 to fuel line 4| between the gas tank (not shown) and fuel pump 42 as diagrammatically illustrated in Figure 2 or piping 40 may lead directly to the float chamber of the carbureter.
A vent pipe 43 connects with the interior of fitting 39 and preferably extends up to about the level of the top of the sight glass 20 for the purpose of venting the fuel line 4I (not shown in Fig. 1 but shown in Fig. 2) to the atmosphere.
While we have shown the coil of the electromagnet connected to the primary side of the ignition coil, it will be understood that where such coil is not readily accessible one side of the electromagnet may be connected to the ungrounded terminal of the battery charging generator of the motor vehicle. In such case the feed of oil will begin when the engine starts and will stop when the engine stops.
It will be seen that our device when the right number of drops of oil per minte is determined and the feed set for that number, is automatic in its operation; oil feed starting when such feed is needed and stopping when the need ceases.
In installations whereV fuel is fed by gravity to the carbureter, our oil feeding device is connected up so that it delivers its drop by drop feed to the float chamber of the carbureter,
In installations where the fuel is supplied from a vacuum tank the reservoir of our oil feeding y device is set at such a height that the sight feed glass is slightly above the fuel level in the vacuum tank.
Having thus described our invention, what we claim as new and desire to secure by. Letters Patent is:-
l. The combination with an oil reservoir having a bottom outlet, of a needle valve controlling the gravity feed through said outlet, a sight glass below said outlet, a valve chamber below said sight glass and having a bottom outlet, a valve ball normally closing said outlet, an electromagnet having its core projecting into said valve chamber through a side wall thereof, piping for conducting to the fuel line of an internal combustion engine oil passing said ball and an air vent in said line adjacent said ball.
