Improvements in and relating to Grease or Oil Cups or Lubricators
for Lubricating the Moving Parts of Machinery.
I, WILLIAM FREDERIO MATTES, residing at Scranton, in the County of Lackawanna
and State of Pennsylvania, one of the United States of America, Manufacturer, do
hereby declare the nature of this invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:
This invention relates to Grease or Oil Cups or Lubricators, and has for its object
to enclose the working parts and protect them from accidental damage whereby the
cup is available for use on road engines and locomotives. A further object is to
reduce the total height of the device.
The improvement consists in the novel construction and combination of the parts
which will be hereinafter more fully described and claimed, and shown in the annoxed
drawings, in which
Figure 1, is a side view of my invention.
Figure 2, is a vertical central section on the line, X, X, of Figure 1.
Figure 3, is a cross section of the cylindrical projection of the cup, on the line, Y, Y,
of Figure 1.
Figure 4, is a bottom plan view of the piston.
Figure 5, is a vertical section of the feed screw on the line, 5, 5, of Figure 2.
C, is the body of the cup and receptacle for the lubricant. H, is a shank by
which the cup is secured to the part to be lubricated. H², is a hole in the shank
through which the lubricant is expelled. P, is a piston having attached to it the
piston rod, P, the latter passing through the cross-head, T. The cup, C, is extended
upward and forms the cylindrical projection, C2, within which the cross-head, T,
slides. This cylindrical projection has slots, O, in the sides and the cross-head, T,
The sides of the slots liave
has arms, T2, which project through the slots, O.
These notches are
notches, O2, large enough to receive and hold the arms, T.
arranged in pairs, as rights and lefts, on opposite sides of the cylindrical projection, C².
The end of the piston rod, P, projecting above the cross-head, T, has fastened to it a
nut or collar, N, which has a projecting disc, n, nearly equal in diameter to the
interior of the cylindrical projection, C. The rim, t, depends from the cross-head, T,
and fits the interior of the cylindrical projection, C, snugly. The upper end of the
cylindrical projection, C³, is covered by a cap, K, above the parts described. The
spring S, is interposed between the cross-head, T, and the piston, P, and its upper
end fits within the rim, t.
When the receptacle, C, has been filled with grease the operator presses downward
upon the arms, T, which slide in the slots, O, and fastens the arms down by hooking
them into the notches, 02.
This movement brings the pressure of the spring to bear upon the piston, with the
effect of slowly pressing it downward and expelling the groase through the hole, H².
While the movement is progressing the space between the collar, N, and the cross-
head, T, is an indication of the amount of grease remaining to be expelled before the
operation will be suspended by the contact of these parts and the enlargement of the
collar, N, brings it into view through the slots, O, enabling the operator at all times
to observe its position. To further assist him in this observation additional slots may
purpose
be cut through the cylindrical projection, C. The cap, K, serves the double
of protecting the working parts from dust and injury, and of strengthening the
upper part of the cylindrical projection, C².
is
A further improvement has been made in the manner in which the piston, P,
packed. A ribbon of packing, L, is interposed between the piston and the sides of

page_text: the cup, C. This ribbon is held in position by being pressed into a groove, G, in
the piston, by means of the wire W. The ends of the wire are conveniently secured
by being turned in through the hole in the piston and then twisted together, as
shown in Figure 4.
The feed to the opening, H2, is adjusted by the feed screw or plug, E, which has a
longitudinal slot, e, in its lower end. The head, e', of the feed screw is adapted to
overlap the sides of the opening, B2, and prevent the escape of lubricant when the
screw is turned down to its lowest limit. When the feed screw becomes loose it can
be tightened by spreading its lower end, which can be done by introducing a chisel
in the slot, e, and giving it a smart blow. The head, el, may be slotted for a screw
driver, or made with flat sides to be operated by a wrench, inserted when the cup Ü
has been removed.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is―
1st. The combination, with the cup, provided with a slot in the side of the upper
part thereof and having a notch extending from the side of the slot, and the piston
working in the cup, of the cross-head arranged to slide within the upper part of the
cup, a spring interposed between the cross-head and the piston, and an arın projecting
from the cross-head and extending through the said slot in the upper part of the cup,
substantially as and for the purpose described.
2nd. The combination, with the cup, having slots in the upper part thereof, and
the piston, of the cross-head having arms that extend through said slots, and the
spring placed between the piston and the cross-head, substantially as and for the
purpose described.
3rd. The combination, with the cup having slots in the upper part thereof, the
armed cross-head, the piston, and the piston-rod passing through the said cross-head,
of a projecting collar secured to the piston-rod above the cross-head, substantially as
and for the purpose described.
4th. The combination, with the cup having slots in the upper part thereof, the
armed cross-head, the piston and the spring, of the cap, K, for strengthening the
upper part of the cup and protecting the operating parts substantially as set forth.
5th. The combination, with the cup having a feed hole in the bottom, of the piston
having the groove, G, packing, L, and wire, W.
6th. The combination, with the cup having the cylindrical projection, C², provided
with slots, O, and with notches, 03, of the piston having the rod, P2, the cross-head
having the depending rim, t, the arms, T2, and the spring interposed between the
cross-head and the piston having its upper end fitting in the rim, t, substantially as
described.
7th. The combination, with the cup having a feed hole in its bottom, of the feed
screw having a head to overlap the sides of said feed opening, substantially as
described.
8th. The combination, with the cup having a feed hole in its bottom, of the feed
screw having the slot, e, in its lower end, substantially as described for the purpose
specified.
