MULTIPLE OIL-FEEDER.

SPECIFICATION forming part of Letters Patent No. 710,928, dated October '7, 1902;

Application filed June 20. 1901. Serial No. 651353. (No model.)

To all whom it may concern:

Be-it known that I, ALEXANDER WINTON, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented new and useful Improvements in Multiple Oil-Feeders, of which the following is a specification.

My invention relates to improvements in multiple oil-feeders, and pertains to an oilfeeder especially constructed for use in connection with motorvehicles, though it is adapted for use in other connections where a plurality of feed connections are used.

In motor-vehicles a com mon oil-supply tank is provided, from which the oil is distributed through separate communications to different parts of the engines to keep them sup- In order to prevent a flooding of the oil when the engine is not working, it is necessary to cut off the supply. It is found to be objectionable to provide separate needle-valves for each communication for the reason that such a construction requires a separate manipulation of each valve to cut off the supply of oil, and, secondarily,for the reasonthat it is not practical in motor-vehicles, owing to the jars of the machine, to determine the proper feed of the oil.

In my present invention I provide a construction whereby the operation of a single valve will cause the supply to be automatically cut off from all of the passages or communications, leaving suflicient oil for again starting the engine.

In the accompanying drawings, Figure 1 is a view showing the supply-tank in elevation and the feed-tank in vertical section. 2 is a top plan view of the feed-tank or chamber,with the top and the float removed. Fig. 3 is a modification showing a form of feed involving the general broad principle, but the preferred construction for the feed to cylinder of the engine.

In the accompanying drawings I am illustrating a construction involving the principle of my invention without attempting to show the various ways in which the principle may be carried out.

Referring now to the drawings,A indicates the supply-tank, and B the supply or feed Fig.-

chamber. .The supply and feed tanks are placed in communication through the medium of a pipe or passage-way 1, having therein a controlling-valve 2 of any suitable form. The inlet end of the tube 1, which communicates with the feed-chamber B, is provided with a needle-valve seat 3, communicating with a depending bushing 4, having passageways 5, in turn communicating with the space 6, surrounding the said bushing.

' The feed-chamber B contains a receivingchamber 7, which contains the float 8. This float 8 is provided with a vertically-arranged guiding passage-way 9, into which a guidingrod 10 extends, the lower end of the rod being connected suitably with the bottom of the receiving-chamber. Surrounding the receiving-chamber are a plurality of. cavities l1 and 12, said cavities being arranged in pairsthat is to say, the recess'll is a receiving-recess, while the recess l2c'ommunicates with the feeding-pipe 13. Therefore to each feeding-pipe there is a pair of recesses, one being a receiving and the other a feeding recess. Each pair of recesses is provided with a wick 14, which has its end extending,respectively, into said recesses and over the upper dividing-wall thereof. The wall of the receivingchamber 7 is provided with a passage-Way15 for each of thereceiving-recesses 11, and this passage-way is placed at the point intermediate the length or depth of the receivingrecesses.

Projecting upward from the float 8 is a cutoff-valve stem 16, carrying at itsupper end a needle or other suitable valve 17, adapted to coact with the valve-seat 3 and to close and open the same. v

Preferably the passage-way 20, which communicates with the engine-cylinder, is provided with the regulating screw -valve 21, adapted tocontrol the lateral passage-way 22, establishing communication between the cylinder-feeding recess 23 and the receiving-tank 7 of the feeding tank or chamber B.

In practice it is found that the wick-feeders are exceedingly efflcient and well adapted for use in connection with motor-vehicles. However, unless some means is provided for cutting off the flow of oil to the receiving-chamber each wick must have one of its ends lifted from its feeding-recess 12 through the medium of a suitable handle or other device 25. The removing of the ends of the wick is very objectionable, owing to the oil upon the lifting members. One feature of my present invention is to avoid the necessity of lifting the wicks and yet cut off the supply of oil. The manner in which this result is accomplished will be fully understood from the following explanation of the operation of the invention: The controlling-valve 2 being open, oil is fed to the receiving-chamber 7 until it has raised the float 8 sufficiently to cause the needle-valve 17 to close the valve-seat 3. When the oil has reached a sufficient height in the receiving-chamber to cause the valve 3 7 to close, the oil in the receiving-chamber is sufficiently high to overflow through the openings 17 into the receivingrecesses 11. The oil is then fed through the wicks to the feeding-recessesl2 and passes from thence through the feed-pipes or passage-ways 13 to their respective points of the motor mechanism. Through the medium of the float the oil (as will be readily understood) is kept automatically at the proper height within the receivin g-chamber to keep the receiving-recesses 11 constantly supplied with oil so long as the controlling-Valve 2 is open. hen the motor is stopped and the vehicle is not to be further used for any considerable amount of time, the controlling-valve 2 is closed. The oil will then continue to feed until it reaches a level below the opening 15 and the receiving-recesses 11 have been emptied. The amount of oil which is fed to the parts of the mechanism after the controlling-valve is closed is regulated by the amount of oil in the receivingchamber above the openings 15 and the size of the receiving-recesses 11. This flow of oil after the controlling-valve is closed is about sufficient to have the mechanism supplied with oil for the next starting of the vehicle.

The reason for not having one end of the wick dipping directly into the receivingchamber 7 is that a considerable amount of oil in the receiving-chamber is necessary to give the float sufficient buoyancy to positively close the shut-off valve 17, and this large amount of oil (in the event that the wick dips directly into the receiving-chamher) would be fed when the supply from the tank had been cut off. By having the wick dip into an intermediate receivingrecess having anoverflow communication with the receiving-chamber the amount of oil fed atter the supply is cut off is readily regulated by the size of the receiving-recess.

From the above description it will be seen that I avoid the necessity of lifting the wicks from the receiving-recesses, which would be necessary to stop the flow of oil unless separate valves were provided for the separate pipes or passages 13.

Where the wicks are used, they control the amount of flow to the respective parts to be oiled, while in the construction shown in Fig. 3 the screw-valve 21 serves that function; but when the screw-valve is once set at the proper point it does not need to be afterward disturbed, for the action of the mechanism in cutting oi the oil by a single controllingvalve is present in the construction shown in Fig. 3, as well as when the Wick-feed is used.

Having now described my invention, what I claim, and desire to secure by Letters Patent, is-

1. An oil-feeder comprising a supply-tank, a receiver in communication with said tank, a float operating a Valve controlling said communication, a receivingrecess having an overflow communication with said receiver, a feed passage-way having communication with said receiving-recess, and a controllingvalve for said tank communication located between the float-valve and said tank.

2. An oil-feeder comprising a supply-tank, a receiving-chamber having communication with the tank, a controller for said communication, a receiving-recess having an overflow communication with the said chamber, a feedrecess out of communication With the said chamber, and a capillary member establishing communication between said receiving and feed recesses.

3. An oil-feeder comprising a supply-tank, a receiving-chamber in communication therewith, a controller for said communication, a plurality of receiving-recesses having each an overflow communication with said chamher, a feed-recess for each receiving-recess, and capillary members extending into all of said recesses and establishing communication between them in pairs.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.

ALEXANDER. VVINTON.
