OF SAME PLACE.
OIL-CUP.
SPECIFICATION forming part of Letters Patent No. 583,668, dated June 1, 1 897. Application filed November 19, 1896. Serial No. 612,707. (No model.)
To a/ZZ whom t may concern:
Be it known that I, ERNEST S. BOWEN, a citizen of the United States, residing at Auburn, in the county of Oayuga and State of New York, have invented certain new and useful Improvements in Oil-Oups; and I do hereby declare the following t-o be a full, clear, and exact description of the invention, such as will enable others -skilled in the art to which ro it appertains to make and use the same.
My invention is an improvement in oil-cups; and it consists in the novel features hereinafter described, reference being had to the accompanying drawings, which illustrate twoforms in which I have contemplated embodying my invention, and said invention is fully disclosed in the following description and claims.
Referring to the said drawings, Figure 1 represents an elevation of one form of oil-cup embodying my invention, showing the cap or cover raised. Fig. 2 is a vertical sectional view of the same. Fig. 3 is a similar sectional view showing the cap or cover in closed position. Figs. 4, 5, and 6 are views similar to Figs. l, 2, and 3, illustrating another form of oil-cup embodying my invention, which is my preferred form.
In the drawings, Figs. 1, 2, and 3, A represents a cylindrical shell or casing provided on its exterior intermediate its ends with a laterally-extending flange a, polygonal in cross-section, as indicated in Fig. l, so that it can be turned with a wrench. Below said yflange the shell is provided with a screwthreaded portion a', which screws into a suitable screw-threaded aperture in the part to which the oil-cup is applied.
B represents a cap or cover which fits snugly over the upper part of the shellAand extends down over it to the iiange a, so as to cover all of the shell above the flange when the cap is in closed position, as shown in Fig. 3.
b represents a piston or plunger within the shell A, fitting snugly therein and having a stem b extending through a guiding-aperture ab' in the head a2 of the shell, secured to the top of the cap B preferably by passing said stem through an aperture in the top of said cap and riveting the stem, as shown in the drawings,but it may be secured in other ways.
C represents a coiled retracting-spring surrounding the stem Z1 between the head a2 of the shell and the piston b, so as to hold the cap B lnormally in its closed position. In this 5 5 instance an oil-inlet aperture CL4 is provided in the side of the shell A just above the nor.- mal position of the pistonl b, as shown in Fig. 3.
The lower end of the shell or casing A is 6o ordinarily provided with'a discharge or delivery tube D, as shown, which is usually made of smaller bore'than the shell and is of any desired length; but this tube may be omitted, if desired, as indicated in dotted 'lines in Fig. 3, in which case the lower end of the shell will simply be provided with a discharge-aperture.
. The operation is as follows: To oil, the cap or cover B is lifted, thereby lifting both the 7o cap and piston above the oil-inlet a4, so that the nozzle of an oil-can may be inserted and the oil introduced into the interior of the shell. It will be noted that the oil is discharged int-o a clear space within the shell and that there is Vnothing to impede its progress to the discharge aperture or tube. W'hen the oilcan is removed and the cap released, the cap will be forced down by the spring O, which also forces down the piston b. As soon as the 8o lower edge ofthe pist-on reaches the bottom of the oil-hole d4 the further downward movement of the piston will eXert a downward pressure upon the air between it and the oil and help to eject the oil through the discharge 8 5 aperture or tube. It will also be noted that should the oil-cup be inverted, as it would be if attached to the hub of a revolving wheel or pulley, the oil would be prevented by the piston b from getting back to the oil-inlet a4 and 9o so leaking out of the cup. It will also be seen that when the cap is in closed position no part of the device which has in any way come into contact with the oil or the nozzle of the oilcan is exposed, so that there will be no oily parts exposed to collect dust, and when the cap is raised the insertion of the nozzle of the Y oil-can into the inlet-aperture a4 will not carry any dust or grit into the shell A and so into the bearing.
In Figs. Il, 5, and 6 I have shown what is my preferred form of oil-cup embodying my invention, the same being a slight modification of the form shown in Figs. 1, 2, and
IOO
adapted to completely cover all of the shell! above the liange e and to rest upon said flange when in closed position.
g represents the piston, filling the interior of the shell E and provided with a hollow stem `r/,closed at its upper end,which extends up through the aperture c3 in the head e2 of the shell and is secured to the cap G in any desired manner, as by riveting, but it may be screwed into the head, if desired.
H represents a coiled retracting spring which surrounds the stein g' between the piston g and the head of the shell, as in the form first described, to hold the cap and piston in their lowest positions. In this form of my invention the oil-inlet aperture g3 is formed in the hollow stem g instead of being in the wall of the shell. Vhen the cap is raised, the piston and stein g will also be raised, thereby exposing the inlet-aperture g3 in the ste1n,through which the oil is introduced into the interior of the stem and so into the shell. It will be seen that the oil has a free and uninterrupted passage froin the inlet-aperture down through the stem and shell and through the discharge aperture or tube of the latter, and hence the oil can be forced in in large quantities without backing up and flooding the exterior of the device, as is the case with many of the oil-cups now in use. Vhen the cap is released and the oil-can removed, the spring H'will draw down the cap and piston, and as soon as the inlet-aperture glias passed into the shell E the further downward movement of the parts will cause a downward prcssure upon the air between the oil and the piston and stem, thus aiding in expelling the oil. It will be noted that this forni of oil-cup projects very slightly above the part to which the cup is secured, which makes it less conspicuous, less in the way, and less liable to injury. vAs in the form irst described, so in this form the parts which come in contact with the oil or oil-can are entirely covered when the cap is down, and there is no danger of the oil leaking out, even if the cup is inverted.
That I claim, and desire to secure by Letters Patent, is
l. In an oil-cup the combination with the oil-receiving shell, of'a movable cap inclosing the upper portion of said shell, a piston within said shell adapted to exert a downward pressure when moved downwardly, to force the oil from the shell, said shell being adapted to receive oil when the cover is raised, a stem connecting said piston and said cap and a retracting-spring interposed between the top of the shell and said piston for moving said cap and piston downwardly, substantially as described.
2. In an oil-cup the combination with the cylindrical shell, of a piston within the saine, a cap normallyinclosing the upper portion of said shell, said shell being adapted to receive oil when the cap is raised, a stern connecting said cap and piston and extending through an aperture in the head of the shell, a retracting spring encircling the stem, interposed between the piston and the head of the shell, substantially as described.
3. In an oil-cup the combination withthe cylindrical shell, of a pistonwithin the same,
a cap engaging the upper portion of said shell, a hollow stem connecting said piston and said cap, passing through an aperture in the head of said shell and provided with an inlet-opening, and a retracting-spring surrounding said hollow stein between the piston and the head of the shell, substantially as described.
In testimony whereof I affix my signature in presence of two witnesses.
