AUXILIARY oILING nevica Manon o. clarkson, Atlanta, ce. Application November 21, 193e, serai No, 112,132 s claims. (ci. 1st-se) Generically this invention relates to oiling systems but it more especially is directed toan auxiliary system `more particularly adapted to auto-k mobile engines of the'internal combustion type.

`5 [One of the principal objects of this invention is the provision of an auxiliary oiling system'for automobile engines and the like adapted to supply oil under pressure tothe cylinder"walls,v con'- necting rod bearinga Wrist'pin bearingsand all "connections requiringoiling, prior to the vstarting of the motor and operation of,the ,primary oil-- `ing system.

Another important object fof" this invention is the provision of an auxiliary oiling system for "is internal combustion engines and the like Wherein actuationof the starter button effects operation of the auxiliary system to 'pre-oil the cylln `der walls and otherimportant operating parts prior to the actuals'tarting `of the starter mechanism and the motor.` j Y A further important object oi'thisv invention is the provision of an 'auxiliary oilingsystem for` automobile engines andthe like electrically con'- nected with the starter, button and including an y auxiliary motor and high `speed pump whereby `actuation of the starter button effects operation of the auxiliary motor and pump to` rapidly de-` liver oil to the operating parts of the'motor in advance of the operation of the starter and 'automatically closing the circuitto the starter and effecting starting ofthe engine.

A stilltfurther important object of thisV invenltion is the provision oi an auxiliary `oiling system for automobile engines whereby actuation of the starter `button initially'efiects' operation Aof the auxiliary oiling system and successive automatic l operation of the starter, engine and primary oil Y this invention there is shown an automobile ening systems, when the auxiliary system has attained a predetermined oil pressure, without vappreciable lag inthe starting of the motor during actuation of the starter button.

,f With these and other'objects in view, which will become apparent. as the description proceeds,

the invention resides inthe construction, com- 45 bination and arrangement of parts, hereinafter more fully described andy claimed, and illustrated in the accompanying drawing, in which like characters of reference indicate like parts throughout the several gures, of which:

tion of the engine shown in Fig. 1.

u It is wen known that-when the conventional` type, of internal combustion engine has been stopped the heated lubricating oil quicklyows; from the cylinder walls and pistons andwhen the engineis started the operatingparts initially operateduring the `time required for the ordinary d pumping vrsystem to deliver toll thereto, without lubrication. ,f This,` ofcourse, is not conducive to long liie of such operating parts andv especially in cold weather maycause `damage thereto'byA reason of non-lubrication and quick' temperature changes. While attempts have been made to remedythisfsituation, those with .which I am familiarhave proven decient in 4only applying to certain parts or using special types of oil from auxiliary oil supplies `and requiring extensive equipment and modification to install, andit was toovercome these and other deciencies by pro viding an auxiliary oiling system in conjunction with the primary system, including a high speed f auxiliary pump` and small motorelectrically conm nected with the starter mechanism and button, so that actuation of the starterl buttonr initially effects operation of the high speed pump to deliver oil from the usual oil well or sump to a prev determined -point for deliverythrough the prlm mary system to all operating parts oi' the en gine prior to the ystarting of the motor, and so designed that when a predetermined` oil pressure is reached,` anelectrical contactwill Ioperate to close a `circuit through the vstarter to start, the a, engine and effect operation of the primary sys tem "in the usual way, and without maintaining saidbutton depressed appreciably longer than eil fectiveV to startv the motor in the usual manner,` that I designed the auxiliary oiling system form- S5 ing the subject matter of this invention.

y In. the illustrated embodiment .characterizing gine A and an auxiliary oiling system B'includ,

ingl an operating electricalclrcuit C. The engine ,m

A comprises the conventional block i, oil VWell or sump 2, strainer 3, oil pump t, suction line t, ine terconnecting'sald pump or oil supply andpump tand' an oil conduit 6 extending from pp fi to one edge of the block and havingmounted m therein oil` pressure relief valve l. Spacedupwardly from conduit t is a substantially paratk lelly extending conduit 8 communicating witlrd .discharging into the primary engine oil syst-em,

and connected to conduitv by conduit t. K Mount- 5@ ed in said conduit or pressureV line t adjacent to conduit @is 'a check valve iii.l A conduit section ll extending in` spaced parallelism with respect to conduit d also -interconnects conduits@ amid.

and is normally closed at one end by reliei' Valve gg n 1. In alignment with section II and with one end communicating' with conduit 8 and the other with an oil pressure gauge and also valve tappets, not shown, is oil line I2 and mounted in conduit 8 adjacent lines II and I2 is check valve I3, said conduit 8 terminating at one end in chamber I4 of greater diameter than said conduit. Chamber I4 communicates with bore I5 of larger diameter than saidchamber and extends to the outer wall surface of the block. Mounted in said bore I5 is a plunger I6 on the stem I1 of which is mounted spring I8. AThe free end of plunger I1 isv adapted to extend through plate I9 forming a closure for-bdre I5, and suitably secured to said block mountedwn plate I9 is a frame 20 suitably secured by set screws 2I formed with a centrally disposed opening 22 in which is suitably mounted insulation block 23 in which is mounted contact member 24 with its inner end extending within frame 20. Said stem I1 is adapted to engage contact 24 when. pressure in chamber I4 is applied to plunger I6, stem I 1 being normally maintained out of engagement therewith by spring I5, as will hereinafter more fully appear.

The auxiliary pump 21 and oil line connections will now be described. Communicating with oil sump 2 and strainer 3 is auxiliary suction line 25 extending to a point spaced belowrelief valve 1 and thence outwardly and with its free end suitably connected as at 26 to auxiliary high speed pump 21 suitably mounted with respect to block I. Pressure oil line 28 has one end suitably connected topump 21 as at 29 and the otherend suitably extending within block I' above relief V valve 1 to a 'point spaced from conduit II and. thence upwardly in parallelism therewith andv communicating with chamber I4, as willbe apparent. Mounted in said line 25 above Astrainer 3 is a union 38 so that said pipe line may 'be broken for cleaning and the like. Suitably mounted adjacent pump 21 and connected there' to by drive shaft 3| is an electric motor 32 for driving said auxiliary high rspeed pump, as and for a purpose directly more fully appearing.l

The circuits by which the auxiliary motor 32 and starterl 33 are operated will now be described.

`Battery 34 is grounded as at'35 and from said battery electric current is adapted to flow through conductor 38 to contact point 31 and from contact point 38k through conductor 39 to motor 32 and conductor 40 to ground, completing the circuit through motor 32 when starter button v4I is brought into bridging engagement with contacts 31 and 38 to close said circuit, andoperate high speed pump 21 to draw oil from sump 2 through suction line then said oil is directed through pressure line 28 to chamber I4, through valve I3 and conduit 8 to the primary engine oiling system, not shown, for distribution of the oil to the cylinder' walls, main bearings, connecting rod bearings, wrist pin bearings and other vital operating parts of the engine, as will be Well'understood. This operation, of course, precedes the operation of the primary oil pump 4, as will directly appear.

When a predetermined pressure has been built up in chamber I4, plunger I6 will overcome the tension of spring I8 and move stem 31 to engage contact member 204, which will complete the circuit through conductor 42 to relay 43, conductor 44, to battery 34 to ground, thus completing a ground circuit and from conductor 44 through conductor 45, and as core 46 is energized contact,

41 is moved into -engagement with contact 48, closing the circuitfrom the battery through conab`ove described, and instantly 25 through pump 21 and ductor 49, and starting mechanism 33, to ground 50, thus starting the engine and operating primary motor 4 to draw oil from sump 2 through suction line 5, pump 4, pressure line 8, conduit 9 to conduit 8 and, thence through the primary oiling system heretofore referred to and, after the motor is started button 4I is 'released,open ing the circuit to motor 32 which stops pump 21, at which moment valve I3 closes, and the oii in said chamber and line 28 drains back through,V

- pump 21 relieving the pressure in said chamber `and allowing spring I8 tomove plunger I8 to its initial position, opening circuit 42 and breaking the relay circuit to starter 33 and stopping the same, as will be Well understood.

The operation of the device will be suillciently clear from the above description as to render further explanation of the operation of the auxillary system unnecessary, except it will be noted that all the above operation takes place during the holding of starter button 4I in engagement with contactsg31 and 38 and without any apparent lag in the starting of the motor, so that in so'far asit is apparent to the operator, actuation of starter button 4I effects starting of the `motor in the usual manner.

l When starter button 4I is depressed, bridging contacts 31 and 38 and eilecting starting oi' motor 32. high speed pump 21 quickly delivers oil through suction line 25, pump 21, pressure line 28,

chamber I4, conduit 8. system, and as soon as to the primaryengine oil a predetermined pressure limited to any amount of operating pressure de- 'slred by the tension of spring I8, the circuit is closed through relay 43 to storage battery 34. thus energizing the core and closing the contacts of said relay 43,'which completes the circuit from battery 34 through the starter 33, operating said starter to eiect starting of the engine and bringing into operation the primary' oiling system as the starter is in operation the pressure on starter button 4I is released, thereby opening the circuit and effecting stopping of the auxiliary motor and starter, as heretofore described. l

From the above it is apparent that the operating parts of the motor which become dry when the motor is cut off will, instead of having to run` without lubrication pending the delivery of oil through the primary oiling system after the motor is started, be pre-oiled before movement is imparted to said parts by starting'oi' the engine by the starter, and, therefore, damage to such parts is prevented and their length of life and smooth running qualities greatly` increased.

It will be apparent that I have designed an auxiliary oiling system, including electrical circuit arrangement controlled by the starter button adapted to operate in advance of the primary oiling system, simple in construction, applicable to existing engine structures with slight modification according to the particular type of engine, manufacturable at a minimum of cost, and emcient for the purposes intended.

Although in practice I have found that the'A may be resorted to within the scope oi' the 'ap- 75 pended claims without departing from or sacrificing any of the principles of the invention.
