UNITED STATES Patented January 3, 1905.
SPECIFICATION forming part of Letters Patent No. 779,357, dated January 3, 1905.
Application filed May 25, 1899. Serial No. 718,296.
To all whom it may concern:
Be it known that I, LEVI S. GARDNER, a citizen oi' the United States, residing at New Orleans, parish of Orleans, State of Louisiana, have invented a certain new and useful Improvement in Oil-Cups; and I declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.
My invention has for its object the production of an oil or lubricating cup in which there is provided a separate pressure-passage and a separate oil-passage with means torsimultaneously cutting both off, and also means for regulating the flow of oil which will not be affected by the temporary cut-off.
The invention consists in a combination of devices and appliances hereinafter described and claimed.
In the drawings, Figure 1 is a vertical section of my oil-cup. Fig. 2 is a cross-section on the line 2 2 of Fig. 1.
In carrying out the invention, A represents a. suitable casting bored transversely to receive the plug or cook B, the latter, as well as its seat, being tapered, as shown, and the plug B held in place and regulated by the nut I). Tapped onto the fitting A and supported thereby is the plate 0, having the vertical tube 0 open at the lower end. and engaged to the fitting A at this point. Extending vertically through the fitting A and plug B are two passages D E.
F is a tube set into the fitting A and communicating with the passage E.
Mounted on the plate C is the glass cylinder G, held in place by the upper plate G, tapped onto the exterior of the upper end of the tube 0.
H is a plug tapped into the interior of the upper end of the tube oand having the hand- Wheel 70, whereby it may be screwed into and out of place. The tube 0 is slotted vertically on opposite sides, as at 0', to permit the level of the oil to equalize in the cylinder G and tube 0.
Set into the fitting A on its lower side and communicating with the passage D is a short tube (Z. l
Tapped onto the fitting A at 1' is a hollow fitting J, having slots 1' therethrough and provided with a glass cylinder J. The fitting J is engaged to the casing of the part it is desired to lubricate.
Extending longitudinally into the plug B is a regulating-screw K, the point 7 of which is adapted to close the passage D or to regulate the flow through the latter. If desired, a packing cap or nut K may be provided.
The operation of the device is as follows: By removing the plug H the cup may be filled. By turning the plug B through the handle B until the passages D E register with the corresponding passages through the fitting A the oil will drop down through the passage D and tube (Z, while the pressure will be equalized through the passage E and tube F. By means of the screw K the flow of oil is regulated. When it is desired to fill the cup with oil, the handle B is thrown, thus revolving the plug B and cutting off both passages D E. The oil-flow and pressure are thus both shut off without disturbing the oilregulating screw and the cup can be filled without the sight-feed chamber (the cylinder J) filling with oil. In other words, when it is desired to fill the cup the operator has only to turn the plug B, thus shutting ofl' all the passages and maintaining the parts in the same position until the plug is turned again, when the oil resumes its flow without disturbing the relative arrangement of the parts.
It is obvious that the regulating-screw K might be located at some other point and IOC or cover having screw-threaded engagement with the upper end thereof, a cylindric shell clamped between said cup and base and forming the side walls of the oil-reservoir, a screwthreaded closure for the upper end of the slotted tube, a fitting having two passages therethrough, having screw-threaded engagement with the lower end of said slotted tube, a cut-off valve controlling both passages and a regulating-valve seated in the cut-off-valve closure and controlling one of said passages, substantially as described.
2. In a lubricating-cup, the combination with an oil-reservoir comprising a base, an integral slotted tube opening axially therethrough and provided with screw-threads in its lower end and on its upper end, a cap or cover having screw-threaded engagement with the upper end of said tube, a shell between said cap and base forming the side Walls of the oil-reservoir, a removable closure for the upper end of the slotted tube, a fitting having screw-threaded engagement with said base in the lower end of the slotted tube and having two passages opening into said slotted tube, a cut-off valve controlling both passages, a regulating-valve controlling one of said passages, a sight-feed chamber below said fitting into which said passages open at their lower ends and a tube extending longitudinally of the oil-reservoir within said slotted tube communicating with one of said passages.
In testimony whereof I sign this specification in the presence of two witnesses.
