UNITED STATES PATENT OFFICE.
CHARLES A. ROBERTSON, F JACKSON, MICHIGAN, ASSIGNOR TO MONTGOMERY WARD 8: COMPANY, OF, CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.
LUBRIGATOR.
Application filed March 24, 1924. Serial No. 701,262.
TouZZ whom it may concern:
Be it known that I, CHARLES A. ROBERT- son, a citizen of the United States, residing at Jackson, in the county of Jackson and I State of Michigan, have invented certain new and useful Improvements in Lubricators, of which the following is a specification.
The present invention has for its primary object the provision .of a lubricator of the gravity feed type designed for use particularly with internal combustion engines, and of such construction as to insure proper feeding of the lubricant against the pressure due tothe explosion of the combustible mixture.
In the ordinary construction of this type of lubricator as commonly employed with explosive engines, the gases from thecylinder 2 find ther way into the feed tube of the lubricator. This pressure from the explosives thus arising impedes the feed of the lubricant, and the latter is prevented having proper access to the interior of the cylinder.
To avoid this is the purpose of the hereindescribed .invention,.its aim being to provide 7 simple and efficient means for insuring passageofthe lubricant from the cup to the interioinof the cylinder freed from the back 3 pressure ofthegases, and thereby capable of movement without interference by such back pressure.
A further object of .the invention is the provision of means for relieving the lubri- 3 catorof the accumulation of the gases so that liability of the lubricator being rendered inoperative, due to the pressure of the accumulated, gases, is eliminated.
7 Other objects and advantages of the invention will appear as the nature of the improvements is better understood, the invention consisting substantially in the novel construction, combination and arrangement of parts hereinafter fully described, illustrated iin the accompanying drawings, and finally pointedout in the appended claims.
It :is to-be .understod that the form of the invention herein shown and described is an expressioniof but one embodiment thereof,
and such disclosure is to be takenmerelyin an :illustrative rather than a restrictive sense.
In the drawings,
Fig. 1 is a vertical sectional view of a lubricator constructed in accordance with the present invention and illustrated in applied relation to an explosive engine;
Fig. 2 is a sectional plan view on the line 2-2, Fig. 1.
of the cooling water.
The cylinder 11 is provided with a port 13 which communicates with the interior thereof, and through which the lubricant is introduced.
The numeral 14 designates the cup of an ordinary gravity feed lubricator which is provided with suitable mechanism for controlling the passage of the lubricant from the cup to the cylinder 11.
This forms no part of the present invention, and any cup provided with such mechanism may be utilized.
Depending from the lower end of the cup 14 is a feed tube 15 which .is suitably connected to the threaded boss 16 at such lower end.
The feed tube 15 is of sufficient length to pass down into the port 13 so that its lower end will be in close proximity to the inner end of said port.
'1 he diameter of the feed tube 15 is considerably less than the diameter of the port 13, and said feed tube is surrounded by a supporting tube 17 the diameter of which is suliiciently greater than that of the feed tube 15 to provide an annular space 18 between the two tubes. The supporting tube .17 is engaged with the outer end of the port 13, its lower end being open and in communication with the port 13, and connected to the upper end of the supporting tube 17 is an internally threaded coupling sleeve 19. The boss 16 is engaged withthe upper end of the sleeve 19 and is spaced suiliciently from the upper end of the supporting tube 17 to provide a relief chamber 20 between that end ofthesupporting tube .17 Land the boss.
In communication with the chamber 20 is a relief port 21, which is formed in one side of the coupling 19, and this port normally is open to the atmosphere. The feed tube 15 passes through the relief chamber 20 so that the lubricant is fed from the cup 14 downwardly through the tube 15 without contact with the conditions prevailing in the relief chamber 20. I
In the operation of the hereindescribed lubricator as applied to an explosive motor in the manner hereinbefore described, the controlling mechanism is set for the proper gravity feed of the lubricant from the cup. Due to the length of the feed tube 15, the lubricant freely passes downwardly from the cup to the port '13, whence it drops into said port and into the interior of the cylinder 11. The port 13 being normally in communication with the interior of the cylinder 11, it is apparent that the gases arising incident to the explosion of the charges will enter the port 13, and if no provision were made to conduct these gases from the port 13 accumulation of the same would follow, and thus impede flow of the lubricant into the cylinder. This is what occurs where there is but a single passage between the lubricator and the engine cylinder, In the present instance, however, the space between the supporting tube 17 and the feed tube 15 is in communication only with the port 13, and has no communication with the interiOr of the cup 14; neither is there communication with the interior of the feed pipe 15 and the space between that pipe and the supporting tube 15. Hence, any gases entering the port 13 pass into the surrounding space between the tube 15 and the tube 17, flow into the relief chamber 20, and then emerge to the atmosphere through the normally open relief port 21. This relieves the interior of the feed tube 15 from thepressure of these gases, and the lubricant is free to flow downwardly therethrough from the cup 14 to the interior of the engine cylinder. Due to the relief port 21, there is no accumulation of the gases in the space between the tubes 15 and 17, this space forming a conduit through which the gases from the cylinder 11 may escape and pass out of the port 21 to the atmosphere.
