LUBBICATING SYSTEM.'

To all whom it may concern:

Be it known that I, PAUL' DAIMLER, a subject ofthe King of -Wrttemberg, and resident of Untertrkheim, in the Kingdom of Wrttemberg, German Empire, have invented a certain" new and useful Lubricating System, of which the following is an This invention relates to a lubricating device or system such as is used with multiple cylinder engines where the .crank pit of the engine receives the waste oil which is sub- .sequently drawn from saidcrank pit passedv 16 l be used. In such apparatus it is extremely through a iilter and forced again into the parts of the engine in which it is desired to desirable that separate pumps should be used for operatin upon the waste oil and the filtered cooled and purified oil. The pump operating upon the waste oil is naturally of large size and the parts are thereby notso liable to be choked by means of impurities passing through the pump.

According to the present invention a waste oil' pump is employed for drawing off the waste 4oil andfforcing the Asame into a cooler and purifier from which itis drawn 'by means of a smaller clean oil pump and delivered intol a separate tank'whence it is withdrawn and distributed to the various points to be lubricated by one or morelubrieating pumps, all of said pumps being preferably controlledv by means of a common rotary valve.

In the accompanyin drawings which illustrate-one suitable orm of the present invention, Figure 1 is a ypartial cross secil tion through anengine frame provided with a lubricator device according to the present invention. Fig. 2 is a section on a line 2 2 of Fig. 1 with the pipes removed, Fig. 3 is a section on a line 3-3 of Fig. 1 with the pipes'removed, Fig. 4.is an outside view of the common rotary valve, Fig. 5 is a developmentof the valve surface showing the shape of the ports. Fig. 6 is a plan partly in section of the lubricating device, Fig. 7

is a section` on the line VII-VII of Fig. 6, Fig. 8 is a section on the line VIII-VIII of Fig. 6, Fig. 9 is a section on the lines IX-IX of Fig. 6, and Fig. 10 shows 'in somewhat diagrammatic view the course o t the flow of the oil in its circuit.

Referring to the drawin a shaft a. driven byv means of a wheel b 1s provided with Speeication of Letters latent. Application led September 4, 1907. Serial No'. 391,317.

positely -arranged with their narrowends toward one another, the left hand part Fi'g. 4 being shown as provided with a pro- .jection h engaging in a recessed boss j. on the rlght hand part. The two halves are drawn toward one another and against the tapered walls of the valve` casing vby means of a spring k. The gearjwheels f and g are proportioned so as to cause the rotary valve lz. to rotate once for each two rotations of the shaft a. The valve parts L are each provided with aset of two L-shaped grooves m n. The parts m being arranged circumferentially while the parts n are arranged axlally. Thegrooves n' extend on opposite sides of the oove parts m so as to register with two di erent sets of delive ports o and o arranged one on each si e of the central plane of each of the pumps d. One groove in a set therefore first serves on the suction stroke of a pump d to connect a suction port d with a passage d2 leading to the 'barrel of the corresponding pump d and then serves'to connect the passage d2 with each of the delivery ports in a set-o on the delivery stroke of the same pump yWhile the other groove in the same set performs the same functions but with respect to the other set of delivery ports o.

`O11 each outer extremity of the conical parts of the valve t there are provided two further grooves p which are arranged in one plane and control lthe operation of the pumps gy -and 1- respectively, being each adapted to connect the passage g2 or r2 leading to the barrel ofthe pump g or r with the corresponding suction port g or r and corresponding delivery port g or r3. The pump r is made larger than the pump g and is arranged to draw waste oil from the crank chambers through -a pipe connected to the suction port r suitable height so as to preserve the required depth of oil in the bath s. The force pump r delivers 'thewaste oil through a pipe la connected to the deliveryport r3 into a cooler and filter w.4 From the cooler and filter w purified and cooled oil is drawn, through a pipe connected to the suction port g', by

and arranged at a means of the pump lq, from which ,it is delivered through a pipe wf connected tothe delivery port g into the tank s formedjin 'the base platefof'theengine. Thev pipe m" may be extendedso as to conduct the oil tov other tanks if desired 'as shown atx/v2. The

,oil is withdrawn froml the tank s through ppes-zconnected to the -suction ports d y l .the two pumps'd, d, and distributed thereby *i jo. for the twopum'ps d comprises' three such ports. `The number in each set may. be 1n` creased'or diminished as required.l It is obvious alsofthatthe number of, pumpsd maybe varied. With this arrangement the waste oil in the crank chamber s is first' emoved therefrom down to a predetermined levelv by the pump r 4and forced into the cooler and -filter w -as .diagrammatically Ishown in-Fig. 10. After passing through the cooler andfilter 'w it -is transferred by the pump Q to the clean oil tank s', whence it is again transferred by the two pumps d d" to the points to be lubricated through -the two sets of deliveryv ports o' and o.
