LUBRICATING environ.

Specification of Letters Patent.

Patented Sept. 2, 1913.

Application filed May 17, 1912. Serial No. 697,994.

To all whom it may concern:

Be it known that 1, CHARLES C. Doss, a citizen of the United States, residing at Jackson, in the county of Jackson and State of Ohio, have invented a new and useful Lubricating Device, of which the following is a specification.

The present invention relates to improvements in lubricating devices, the primary object of the invention being the provision of a novel means whereby the proper amount of fluid lubricant is fed at all times to oil cups for distribution to the moving parts of machinery, the present invention residing particularly in the conduit leading from the main reservoir to the individual oil cups, whereby the flow of the oil from each oil cup automatically causes the oil to flow from the main reservoir and to be automatically checked at the desired height within the respective oil cups.

With the foregoing and other objects in view which willappear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawingsFigure 1 is a view in elevation of the lubricating device employing a single oil cup. Fig. 2 is a section taken on line 2-2 of Fig. 1. Fig. 3 is a perspective view with a portion thereof broken away illustrating the connection bet-ween the main reservoir and the individual oil cup. Fig. 4 is an end view taken from the lower end of the same.

Referring to the drawings, the numeral 1 designates the main reservoir, which contains the bulk of the lubricant and is provided with a filling opening at its upper end normally closed by a plug or cap 2 and the glass sight gage 3. Leading or depending from the reservoir 1 is a conducting pipe section 4 which has attached thereto, the valve casing 5, whose hand valve 6 normally remains open at all times.

In the present instance, a single transparent oil cup 7 is shown of the usual type, but it is evident that any number of these may be employed as will be found expedient. Leading from the oil cup in the present instance, is the coupling 8, which has disposed therebelow the metal shoe 9 carrying the wick or other lubricant distributing fal ric or material 10, this particular device being especially adapted for distributing the lubricant to crank pins or crank shafts of an explosive engine. Leading from the coupling 8 in opposite directions, as clearly shown in Fig. 1, are the conduits 11 which terminate in the valve controlled distributing nozzles 12 for conveying the lubricant to the explosive chambers or other bearings of the engine. As before stated these particular connections and distributing means are used only to clearly demonstrate the employment of the conduit or pipe section 18 which is attached to the valve casing 5 and which forms a connection between the oil cup 7 and the valve casing. This connection or pipe section 13, as clearly shown in Figs. 2 and 3, is divided longitudinally and centrally thereof by means of a partition 14: into two longitudinal channels 15 and 16.

The lower end of the conduit 18 is provided with an open slot or notch 17 at one side of the partition, which acts as an air vent for the channel 15 and controls the flow of oil from the reservoir 1 into its individual cup 7. The lower end of the conduit or pipe section 13 depends within the oil cup, as clearly shown in Fig. 2, so that the upper edge of the aperture 17 will control the oil line within the cup 7.

The partition 14 is fitted longitudinally within the pipe section 13 with its lower end flush with the lower end of the said pipe section, the lower end of the said pipe section being cut in a plane at right angles to the axis of the pipe section.

It will thus be seen that as the oil is distributed from the cup 7, the level will lower and permit the air to enter through the aperture 17 into the channel 15 and finally into the reservoir 1, thus permitting the oil in the reservoir 1 to flow through the channel 16 into the cup 7, and when the oil has again sealed the aperture 17, the flow of oil from the reservoir 1 will cease. By this construction and arrangement of distributing conduit, any number of oil cups 7 may be fed from a reservoir 1 and the level of the oil within the said cup 7 will be maintained and thus the said cup 7 is continually filled until the supply of lubricant within the reservoir 1 has been used.

The operation of the lubricator may be started in an efficient manner, the valve 6 being closed during the filling of the reser voir 1, so that after the reservoir has been filled, the valve 6 may be opened, with the closure 2 still removed, which will permit the lubricant to flow readily through both of the channels 15 and 16 into the oil cup. Then, after the level of the lubricant within the oil cup has risen to the notch or slot 17, the valve 6 may be closed until the closure 2 is secured in place, thereby sealing or closing the reservoir 1. Then, by opening the valve 6, the lubricant will fiow down the channel 16 as the level of the lubricant within the oil cup lowers, air being admitted through the open slot 17, and any lubricant within the channel 15 being siphoned off through the channel 16. It will be observed that this siphoning action will also take place when the channels 15 and 1 6 are filled, even though the valve 6 is closed, so that the channel 15 may be cleared under all conditions, The smooth operation of the device is also assured for the reason that the lower section of the pipe sect-ion 13 is cut in a plane at right angles to the axis of the pipe section, so that the discharge of lubricant from the channel 16 in no wise interferes with the ingress of air into the channel 15 through the notch or slot 17, it being noted in this connection that the lower end of the partition is flush with the lower end of the pipe section 13.

What is claimed is:

In a lubricator, a reservoir having a filling opening in its upper end, a closure for the opening, a pipe section depending from the reservoir, a valve attached to the pipe section, an oil cup, a pipe section attached to the valve and depending within the oil cup, and a longitudinal partition fitting within the last mentioned pipe section, the lower end of the last mentioned pipe section being cut in a plane at right angles to the axis of the pipe section and being provided with an open slot at one side of the partition, the partition terminating fiush with the lower end of the last mentioned pipe section.

' In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.
