Improvements in Lubricators.
I, JOHN SHERRY, in the City of Rochester, County of Monroe and State of
New York, 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:-
My invention relates to force-feed lubricators, and has for its object the pro-
duction of a device which is particularly simple in construction, is highly
effective in use, and is capable of a maximum adjustment, even when in opera-
tion, and to this end, it consists in the combination, construction and arrange-
ment of the component parts of a force-feed lubricator, as hereafter fully
described and pointed out in the claims. In describing this invention, reference
is had to the accompanying drawings, in which like letters indicate corre-
sponding parts in all the views.
Figures 1 and 2 are opposite face views of my improved force-feed lubricator.
Figures 3, 4 and 5, are sectional views taken, respectively, on lines 3-3,
4-4 and 5-5, Figures 1 and 4.
Figure 6 is a perspective view of the detached governing member of my
invention.
reser-
My improved lubricator preferably comprises in its organization, a
voir A, a shaft B, means for actuating said shaft and controlling the operation
thereof, one or more pumps C, and means for connecting the shaft to the pump
or pumps.
The reservoir A is of any desirable form, size and construction, and is formed
with transverse chambers a a¹, a lateral extension a², a supporting face a3 and
one or more passages at extending through the face a³ and communicating with
the internal chamber of the reservoir. Said chamber a extends through the
upper parts of the opposite walls of the reservoir A, forms bearing for the
shaft B, presently described, and braces and unites said upper parts of the
opposite walls of the reservoir.
The chamber is arranged above the chamber a in a plane substantially
parallel therewith. extends through the wall of one side of the reservoir A,
and is formed with a closed inner end. Said lateral extension a projects from
the base of the reservoir A and is provided with an internal chamber forming
a lateral extension of the internal chamber of said reservoir. The face
substantially flat and forms the upper face of the extension a². The passages a
extend vertically through the face and the top wall of the extension a² and
communicate with the internal chamber of the reservoir.
is
The shaft B is passed through the chamber a and generally projects beyond
both ends thereof.
The means for actuating the shaft B and controlling the operation thereof
consists of a power-transmitting wheel b, a rocking lever 1, an actuating
member 62, a governing member 63, and a hand-piece 64. Said power-trans-
mitting wheel is suitably connected to the shaft B, being preferably fixed to

page_text: the adjacent end thereof, and is provided with a toothed periphery. The lever b
is interposed between the reservoir A and the adjacent or inner face of the
wheel, is loosely mounted on the shaft B, and is suitably connected at its
lower end to any desirable actuating means, not illustrated, which may be
operated by a movable part of the engine or other mechanism to be lubricated.
Said actuating member usually consists of a pawl which is mounted on the
upper end of the lever and engages the toothed periphery of the wheel b for
advancing the same step by step, as the lever is rocked to and fro by the.
actuating means connected thereto.
The governing member consists of a flat disk which is interposed between
the wheel and the lever 1, is loosely mounted on the shaft B, and is provided
with a peripheral engaging face for foreing the actuating member out of opera-
tive position as the lever is rocked in one direction. This disk is supported
upon the reservoir A and preferably by the shaft B and an arm which pro-
jects laterally from the contiguous surface of said reservoir at one side of the
path of movement of the lever b¹, and is provided with suitable means, as a
clamp 66, for permitting said governing member to be easily and safely rocked
on the shaft B during the operation of the lever b in order to adjust the posi-
tion of the face 65 and regulate the operation of the lever b. Said clamp 6 is
also arranged at one side of the path of the lever b¹, is passed through a slot 67
in the governing member, and is readily movable from and into its operative
position.
The hand-piece 64 is connected to the outer face of the power-transmitting
wheel and may be readily and safely operated during the operation of the
fever to effect the operation of the power-transmitting wheel by hand, and
preferably at a greater speed than the same would be operated by the lever bl.
Said hand-piece is provided with an internal chamber which receives a friction-
piece 8 movable through the power-transmitting wheel into engagement with
the governing member 63 for preventing undue movement of the wheel b. The
described means for actuating the shaft B and controlling the operation thereof
is particularly practical, as it permits any desired adjustment of the operation
of the lever without varying the throw of said lever and also enables the
operator to actuate the shaft B by the hand-piece independently of said lever
and during the movement thereof.
Each of the pumps C is provided with inlet and outlet-ports cc¹, suitable
valves, and a piston c, and is also provided with an enlargement or shoulder c
mounted on the face a³ and a reduced lower portion passed through the corre-
sponding passage at and provided with the corresponding inlet-port which
extends through the outer shell of said reduced portion and communicates with
the internal chamber of the reservoir A. The outlet-ports c¹ of the pumps C
discharge into conduits cf which conduct the oil or other lubricant to the desired
locality. From the foregoing description, it will be noted, that the pumps C
communicate independently with the reservoir A, and that each of said pumps
with its inlet and outlet-ports. its valves and its piston may be removed from
the face and the corresponding passage and conduit independently of
the remaining pumps This is a feature of great advantage, as the pumps are
more or less liable to derangement or imperfect operation, and when capable of
ready withdrawal and replacement, a continued stoppage of the lubricator is
avoided.
The means for connecting the pumps C to the shaft B preferably consists of
an actuating member d and independently movable connections between the
member and the pistons of said pumns. The member d. is substantially
Tshaped, is provided with a trunnion d journaled in the chamber a', and is
suitably connected to the shaft B, as by an eccentrically arranged pin c, so
that as said shaft is revolved, the actuating member is rocked on its trun-
nion The connections between the member and the pistons of the
pumps C preferably consist of links ², pivots d³ and clamps d. The pivots

page_text: connect corresponding ends of the links to the pistons c³, and the clamps d
connect the opposite ends of said links to the actuating member d and permit
the adjustment of said opposite ends of the links toward and away from the
trunnion during the operation of said actuating member for varying the
operation of the pumps C. Said clamps are here illustrated as movable in a
slot extending longitudinally through the upper portion of the actuating
member d, but may obviously be movable in any other suitable guide for per-
mitting the desired adjustment thereof.
The construction and operation of my improved lubricator will now be
readily understood upon reference to the foregoing description and the accom-
panying drawing.
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
