Description

March 18A 1924.
INVENTOR CLYDE C. FARMER BY 0% y@ ATTORNEY Patented Ldddyll CLYDE C. FARMER, OF EDGEWOOD, PENNSYLVANIA, ASSIGNOR TO THE WESTING- HOUSE AIR BRAKE COMPANY, OF WILMERDING, PENNSYLVANIA, A CORPORATION OF PENNSYLVANIA.
LUBRICATOR.
Application filed. April 27, 1921.
To all whom t may concern:
Be it known that I, CLYDE C. FARMER, a citizen of the United States, residing at Edgewood, in the county of Allegheny and State of Pennsylvania, have invented new and useful Improvements in Lubricators, of which the following is a speciiication.
This invention relates to automatic lubricating devices, and more particularly to a lubricator for air compressors.
In lubricators adapted for supplying lubricant to the air cvlinder of a compressor, when the filling cap is removed While the compressor is running, for the purpose of filling the lubricator with lubricant, fluid under pressure and perhaps oil is liable to be blown out at the open end of the lubricator, making it disagreeable and difficult to replenish the lubricant supply.
The principal object of my invention is to provide a lubrica-tor having means for overcoming the above difficulty.
In the accompanying drawing, the single figure is a central sectional view of a lubricator embodying my invention.
For the purpose of illustrating one application of my invention, I have shown a lubricator of the type disclosed in Patent No. 1,337,687 of C. L. Bubb, dated April 20,
1920, and comprising an oil cup l adapted to be connected by pipe 2 to thc air cylinder of a fiuid compressor.
Centrally Within the oil cup chamber 3 there is screwed into the base portion of the cup a cylindrical plug 4, having a central bore 5 communicating with the pipe 2.
Mounted on the plug 4 is a sleeve 6, which at the lower end is slightly spaced from the Serial N70. 464,967.
plug 4, so as to provide a restricted feed passage from the oil chamber 3, through which oil is supplied by capillary attraction to a passage 7, leading to the passage 5.
The upper end of the oil cup l is normally closed by a filling cap 8, having screw-threaded engagement with the body of the oil cup.
According to my invention,the passage 5 is diverted laterally at the upper portion of the plug 4, as shown at 9, so that when the cap 8 is removed from the oil cup for filling the chamber 3 with lubricant, if the air compressor is running, the blowing of air and possibly oil will be diverted laterally and will not interfere with the filling of the oil cup, which may readily'be accomplished at the side of the plug opposite the lateral outlet 9, and without danger of getting oil into the passage 5.
' Having now described my invention, what I claim as new and desire to secure by Letters Patent, is
In a lubrica-tor for air compressors, the combination with an oil cup casing and a removable cap having a pocket, of a plug secured within the casing and extending into said pocket and having a central passage adapted to communicate with the com-- presser, and a lateral passage in said plug which connects the central passage with the pocket in the removable cap and through which fluid and oil from the compressor is diverted to one side of the cap to permit filling of the oil cup casing at the other side.
In testimony whereof I have hereunto set my hand.
CLYDE C. FARMER.
