CATING APPARATUS," a communication to me from abroad by Jean Denis
Genoud, Hotel Keeper, of 29, Boulevart St. Martin, Paris, upon the con-
dition (amongst others) that I, the said William Clark, my executors or
administrators, by an instrument in writing under my, or their,or one of their
hands and seals,should particularly describe and ascertain the nature of the
said Invention,and in what manner the same was to be performed, and cause
the same to be filed in the Great Seal Patent Office within six calendar
months next and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said William Clark, do hereby declare the
nature of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement, reference being had to the two Sheets of Drawings hereunto
annexed, and to the letters and figures marked thereon (that is to say):-
This Invention relates to an improved lubricator applicable to the journals
of shafts of bearings generally, which possesses the following advantages :-
This lubricating apparatus may be mounted on the cap of the bearing or at
any other suitable point, the oil being conducted thereto by means of a metal
or india-rubber tube, and this, whatever may be the position of the parts to be
lubricated, whether vertical, horizontal, oblique, or difficult of access, the
supply commencing on the starting of the shafts or other parts from whence it

page_text: receives motion,and ceasing with the stoppage of said motion, in this manner
continuous lubrication when required is ensured.
This Invention is illustrated in the accompanying Drawings, Fig.1,Sheet 1
of which represents a central vertical section of the lubricating apparatus on
line 1, 2, Fig. 2; while Fig. 2 is a horizontal section of same on line 3, 4,
Fig. 1. The same letters and figures of reference apply to both Figures.
a, ordinary bearing, in which turns a shaft b; c, plate carrying the various
parts of the lubricating apparatus; d, oil cup or receiver, of any suitable
form; e, pump barrel, forming a continuation of d; f, metal plug, forming
the base of the pump barrel, passing through plate c, and screwing in the cap
of the bearing at g; h, inlet channel made in plug f for establishing com-
munication between the pump barrel and shaft 6; i,piston, furnished with a
leather packing, which rises and falls in the pump barrel; j, j, injection
orifices, which are closed by means of a leather disc k, when the apparatus is
not in action; Z, metallic ring carried on a stem, and acting on disc k, so as
to close orifices j, j, through pressure exerted by springs m. Motion is
transmitted to the piston in the following manner :-n, n, uprights fixed to
plate c, or they may be cast therewith; o, balance lever oscillating at the
upper part of uprights n; p, collar or strap keyed on shaft b,acting as a cam;
9, lever, oscillating at each revolution of the shaft by the motion of the
cam p; this lever is furnished with a catch r, whereby a ratchet wheels is
caused to rotate to the extent of a tooth, being maintained in position by a
stop pawl t; u, tangent screw, forming the axis of the ratchet wheel, and
rotating therewith; v, screw wheel receiving motion from screw u, and fixed
to a circular incline ; y, axis of same, fixed to the plate by a nut ; on
this axis turns the sleeve 1, to which are keyed the parts vand x; 2, lever
oscillating on a fixed point 3 of party, which lever is raised by the incline,
more or less, according to the extent of its rotation; 4, rod transmitting the
ascending motion of lever 2 to balance lever o; 5, piston rod having a ball at
its lower end,and provided with leather packing; 6, spiral spring, or it may
be other means for returning the piston to the starting point when the incline
has completed its course, and thereby supplying a fresh amount of liquid,
which is drawn into receiver d. The whole extent of motion of the piston is
produced by twenty-two thousand five hundred revolutions of the shaft, during
which time it furnishes a supply of nearly two ounces of oil. It will be
understood that I reserve the right of varying the quantity and flow of the
oil according to the requirements of different kinds of bearings; I also
reserve the right of arranging the parts of the herein described apparatus in
any other manner conducing to the same result. Thus I may also arrange

page_text: this lubricating apparatus in such manner as to render it intermittent or
continuous in its action.
.
One of these improved apparatus, represented at Fig. 1, Sheet 2, consists of
a suitable chamber or recipient furnished with a metallic piston working in
a small cylindro-conical pump barrel. The stem of this piston is furnished
with a spiral spring surrounding the former, and forcing it constantly down-
wards; at the upper part of the tangent wheel or spiral spring is a ratchet
having four spaces forming a cam on which bears a lever fixed to the piston
rod. At each turn of the tangent wheel the lever fixed to the piston rod is
raised four times by the inclined surfaces of the cam, and again returns to its
downward position by the action of the spiral spring. In these four move-
ments the metallic piston is raised four times for introducing the oil, and is
lowered four times for projecting said oil in a jet on the shaft to be lubricated.
Another arrangement represented at Sheet 2, Figs. 2 and 2bis, differs
from the above only by the piston being furnished with a cupped leather
which works in a small pump barrel, and instead of projecting the oil in
a jet allows it to fall a drop at a time in proportion to the extent to which
the piston is lowered by the cam, or by a ratchet wheel having two spaces
which is in this case placed under the tangent wheel. In Fig. 2 the piston
is lowered by means of the cam, and is raised by the spiral spring to permit
of the introduction of a fresh quantity of oil, into the pump body. I also
reserve the application of multiple apparatus of this Invention for lubricating
a number of shafts or bearings simultaneously.
In the annexed Drawings A represents the ratchet; B, recipient fur-
nished with a suitable cover; C, C, piston which is of metal in the one case
and in the other is provided with a cupped leather; D, pipe for conducting
the oil; E, inlet of the oil into the apparatus; F, tangent wheel; G, nut
made in two parts (or ratchet in Fig 2) having spaces forming a cam
surface; H, lever of matchet; I, support of tangent screw J; S, piston
rod; K, lever fixed to the piston rod and which is raised by the inclined
surfaces of the ratchet toothed cam (.
The lubricating apparatus represented at Fig. 3, Sheet 2, is especially
applicable for lubricating several shafts or bearings at one time when the
latter are disposed one beside the other or at slight distances apart; it may
also be arranged for supplying the lubricating matter at several points from
one and tiie same bearing where there is a large area of surface to be
lubricated.
The arrangement of multiple lubricator, seen in Fig. 3, is given only as an

page_text: example of the method of applying this Invention for the purpose of
lubrication at several different points, as it will be readily understood that
the Invention is based not on the form or arrangements, which may be varied
according to the purposes desired and circumstances of each case, but on the
contrary on the principle of the improved lubricating apparatus as herein
described.
It will thus be well understood that the multiple lubricator forming part of
this Invention, although constructed on the same principle, may be arranged
in any other manner than that represented in the Drawing, for example, it
may consist as before mentioned of several distinct chambers each furnished
with its respective piston, and set in motion by a single screw driving each of
the tangent wheels, or there may be a single chamber distributing the oil by
a series of pipes to the different points desired. This multiple lubricator
is shown in central vertical section at Fig. 3, Sheet 2, the various parts being
the same as those already described, with reference to the other Figures.
a, ratchet, furnished with a single pawl b, for regulating the motion of the
apparatus; c, tangent wheel gearing with tangent screw d; f, cam, having
two inclined surfaces running on two friction rollers g, carried by a cross barh,
which latter is guided in its ascending motion by bars k, and actuates the
six lubricating pistons i; j, box of metal or other material forming the
receptacle for the lubricating matter; 7, pipe cast on or fixed to the cover
or box j, and serving by means of a float and rod to indicate the levelof the
oil contained in said box.
Fig. 14, Sheet 2, represents an elevation of a simplified and improved ar-
rangement of lubricator of this Invention. In this Figure it will be seen that
the double camf, instead of being horizontal, is arranged vertically, and acts
on the piston rod i direct. The tangent wheel is also in a vertical plane, and
is mounted on the same axis as cam f, while further the ratchet lever is modi-
fied in an important degree; the improvement consists in dispersing with the
ring or projection fixed on the shaft, and regulating the motion, substituting
therefor an eccentric cam m, which is fixed in the desired position by the aid
of a pin, running in slots n, and by frictional contact with the shaft of the
bearing produces a uniform and smooth motion which is communicated to
lever o.
Having described the nature of this Invention, and the manner of perform-
ing the same, I declare that what I claim as the Invention to be protected by
the herein-before in part recited Letters Patent is,―
1st. The improved lubricating apparatus represented at Figs. 1 and 2

page_text: Sheet 1, of the Drawings, which is suitable for application, in any position, its
distinguishing features being the piston, screw, screw-wheel, and cam.
2ndly. I claim the improved lubricating apparatus for producing an inter-
mittent supply in the form of a jet, as before described and represented at
Fig. 1, Sheet 3, of the Drawings.
3rdly. 1 claim the apparatus of similar arrangement represented at Fig. 2,
Sheet 2 of the Drawings, in which the lubricating matter is supplied drop
by drop in a continuous manner, as before described.
4thly. I claim the application of several of these apparatus in combination
with the object of lubricating several points at one time.
5thly. I claim the improved multiple lubricators arranged according to this
Invention, without confining myself to their form or dimensions, as they may
be varied according to the purpose desired, the principle of which consists in
effecting the lubrication, either in the form of jets or drops, the apparatus
being set in motion by the shaft which is to be lubricated.
In witness whereof, I, the said William Clark, have hereunto set my
hand and seal, this Sixteenth day of September, in the year of our
Lord One thousand eight hundred and sixty-four.
