IMPROVEMENTS IN LUBRICATORS
Year: 1884

page_text: I, HEINRICH PHILIPP JAKOB KESSLER of Oberlahnstein am Rhein in the German
Empire, Manufacturing Engineer do hereby declare the nature of my said Invention
for "IMPROVEMENTS IN LUBRICATORS" and in what manner the same is to be
performed to be particularly described and ascertained in and by the following
statement, that is to say :-
In lubricators as they are usually arranged with capillary wicks the delivery of
oil to the rubbing surfaces is irregular, a greater quantity being delivered when
the level of the oil in the vessel is high than when it is low. Consequently the
surfaces receive sometimes too great and sometimes too small a supply, or, if the
delivery be so arranged as to provide sufficient lubricant when it is low in the cup,
there is great waste by excess of supply when it is high. The object of my
Invention is to correct such irregularities in the flow of lubricant by maintaining a
constant level in the oil cup, providing at the same time for increasing or lessening
the supply as may be required. For this purpose I arrange above the ordinary oil
cup a second oil cup with capillary wicks for supplying the lower cup, as illustrated
by the accompanying Drawings, Fig. I being a vertical section, and Figs. 2 and 3
sectional plans of the upper and lower cups respectively. A is the oil cup of
ordinary construction with its capillary wick f. On the top of this cup I fix by
screwing or otherwise the second cup B, which has a central tube d and several
other tubes d. Any one of these tubes receives a wick g, or when considerable
supply of lubricant is required, several or all of the tubes may have wicks. I
provide also a screw plug q, its screw or the screwed hole in which it fits being
made with taper grooves, so that according as the plug is screwed more or less
down, there is a less or greater flow of oil from the upper to the lower cup. By
this means the supply can be adjusted so as to maintain a constant or nearly
constant level of lubricant in the lower cup A. When the plug q is screwed fully
down, a collar on it stops altogether the flow through the botton aperture of the
cup B. The lower cup A is charged by pouring oil through any of the tubes d';
and, by a wick in the central tube d, oil can be delivered directly on to the wick f
when the greatest amount of lubrication is required. A lubricator as above
described is applicable to engine cylinders and slides, to guides, to the bearings of
connecting and coupling rods, cranks, shafts, and generally to the rubbing surfaces
of engines and machinery,

page_text: Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed, I declare that what
I claim is
1. In combination with a capillary wick lubricator, a second lubricator above it
. arranged to serve as a reservoir of lubricant for maintaining the level of oil in the
lower lubricator, substantially as and for the purposes herein set forth.
2. Constructing the upper reservoir referred to in the preceding claim with
several capillary wick tubes, one or more of which can be used for supplying the
lubricator, as herein described.
3. Constructing the upper reservoir referred to above with a screw plug for
regulating the flow of oil as herein described.
Dated this 6th day of September 1884.
