PROVISIONAL SPECIFICATION.
Improvements in Oil Feeding, Lifting, and Circulating Apparatus,
Applicable to the Bearings or Journals of Shafts.
We WILLIAM THOMSON of Crompton Fold, Shaw, near Oldham in the County of
Lancaster, Mill Mechanic, and GEORGE THOMSON, of Crompton Fold, aforesaid Mill
Mechanic, do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements of a lubricator being the subject of Letters
Patent numbered 237 A.D. 1888 January 6, granted to George Thomson one of the
applicants and an inventor herein.
According to the invention as described in the aforesaid specification of Letters
Patent, the lower part of the spindle is to be immersed in oil contained in a reservoir
or receptacle, as it is essential in the case of waste oil or oil escaping from the journal
that the same shall flow to the spindle by gravitation, consequently in cases where the
lower part of the wall box, standard, or bracket from which part the waste oil dripped
or flowed into the reservoir may be situated some distance from the shaft, and in
practice it is found that it is necessary in such cases to employ a spindle of inconvenient
length, but in accordance with the construction of our present improvement the
rotating spindle is dispensed with, a frictional driving arrangement being employed to
operate this our improved apparatus as in the former invention, the length of our
improved apparatus or oil lifter not being dependent upon the distance which may
intervene between the shaft and the reservoir, the oil provided in or the oil escaping
into the reservoir, which reservoir may be situated at a greater distance from the
shaft than was hitherto convenient or practicable, and withdrawn therefrom by the aid
of suction, and more effectually forced to the oil cup over the shaft or to the part to
be lubricated.
Our invention or improved apparatus consists of a barrel provided with a chamber,
in which is enclosed or situated the end of a ram or plunger, the lower part of the said
plunger being also provided with a chamber, from which extends an orifice terminating
at the end of the plunger, at the entrance to the orifice and situated in the chamber
is a ball valve; the upper part or end of the ram (that is the part extending out of and
above a gland in the barrel) terminates in the form of a cross head or forked shaped
piece, the crosshead is provided with a horizontal spindle upon which is eccentrically
mounted between the fork shaped projections or jaws a friction disc, its periphery
being provided with leather or other material, the extremities of the spindle rest upon
spiral springs, which springs are situated in hollow standards secured to the gland of
the plunger barrel; at the lower end of the barrel I employ a hollow connection or
"tail piece" in which I provide a ball valve; connected to the tail piece is a tube of
any suitable length, terminating with an inverted cone shaped strainer of gauze, in the
reservoir containing the lubricant.
If desired we may, instead of employing the eccentric disc before referred to, employ
a disc axially mounted on the spindle, having eccentric shaped bosses one on each side
of the friction disc, the extremities of the cross head being conveniently connected to
the eccentric bosses or collars.
When our improved apparatus is to be operated, the same is fixed by convenient

page_text: means near to a shaft, in such a manner that the friction dise may be caused to bear
against the surface of the shaft, when the shaft revolves a reciprocating motion is
imparted to the plunger, according to the throw of the eccentric disc, the springs
supporting the eccentric yielding to pressure to any required extent, or according to
the throw of the eccentric bosses as the case may be; the lubricant being then drawn
into the chamber in the tail piece, and at each downward stroke of the plunger is
forced into the chamber situated in the plunger, the lubricant or oil being then caused
to pass out through a side thoroughfare in connection with a tube terminating at the
oil cup or cups at the top of the shaft or shafts to be lubricated. We may use, instead
of the frictional driving arrangement described, toothed gearing to connect the oil
lifter to the shaft.

COMPLETE SPECIFICATION (AMENDED).
Improvements in Oil Feeding, Lifting, and Circulating Apparatus,
Applicable to the Bearings or Journals of Shafts.
We WILLIAM THOMSON of Crompton Fold Shaw near Oldham in the County of
Lancaster Mill Mechanic and GEORGE THOMSON of Crompton Fold aforesaid Mill
Mechanic, 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:
These improvements relate to a lubricator being the subject of a prior Patent
No. 237, A.D. 1888 dated January 6 granted to George Thomson one of the applicants
herein.
According to the construction described in specification No. 237, A.D. 1888, it. is
essential that the lower part of the rotating spindle should be immersed in the oil
receiver, consequently when the receiver is situated at a great distance from the shaft
or bearing as the case may be, it is necessary to employ a spindle of great length; but
according to the construction of our present improvements the length of the lifter is
not dependent upon the upon the situation or distance of the receiver with relation to
the bearing, as the lubricant is by our improvements raised or lifted therefrom by the
aid of suction.
We now refer to the accompanying sheet of drawings, in which like letters of
reference indicate like parts, in order that our invention may appear clear and
intelligible.
Fig. 1. is a front elevation of our invention.
Fig. 2. is an end view thereof.
Fig. 2. is a sectional view, partly in elevation, shewing barrel, piston and oil
chambers.
Figs. 4 3 and 4 are elevations of a modification for actuating piston or plunger.
Our improvements or invention consists of a barrel a, provided with a chamber b,
into which enters a plunger c; at the lower part of the said plunger is provided a
chamber d, from which chamber extends an orifice e; at the entrance to the orifice e
and within the chamber d is situated a ball or spherical piece f; the upper part of the
plunger that is the part extending out of the barrel a and above the gland g-
containing the packing-terminates with a cross head or fork shaped piece h; between
the jaws of the crosshead is mounted eccentrically a disc i, upon the spindle j, to which
it is keyed; the periphery may be provided with leather or other suitable material.
The extremities of the spindle j extend beyond the sides of the cross head h, and
immediately below the said extremities, and in engagement therewith, we provide
spiral coils or springs kk, situated within hollow standards 1. 1. provided with slots m.
At the lower extremity of the barrel a we provide a "tail piece" n, in which we
provide a ball or spherical piece o; to the said tail piece n may be attached a tube or

page_text: pipe p. terminating with an inverted cone shaped strainer-and located within the oil
receiver.
We will now explain the action of our invention.
Our invention is to be fixed by any convenient means contiguous to a rotating
shaft, it may be the shaft the bearing or bearings of which are to be lubricated, being
fixed in such a manner that the periphery of the disc may bear against the surface of
the shaft.
When the shaft revolves, a reciprocating motion imparted to the plunger, more or
less according to the throw of the of the eccentric, the extremities of the spindle
carrying the disc, resting upon the coils or springs, causes the periphery of the disc to
bear against tho surface of the shaft, thus ensuring contact of the dise with the shaft,
consequently the reciprocating motion continues so long as the shaft is in motion;
in consequence of such motion, the lubricant, which may have passed from the journal
or bearing into the receiver, may be drawn therefrom into the chamber in the tail
piece, and at each downward stroke of the plunger the same passes into the chamber
in the plunger and out through a thoroughfare », terminating at the part to be
lubricated.
If desired, we may employ for the purpose of actuating or giving a reciprocating
motion to the plunger, the arrangement shewn in Figs. 4 3 & 54, or any other modi-
fication which may be found convenient. Figure 4 represents the disc i, axially
mounted on the spindle j, and provided with eccentric shaped bosses t, in one piece
with the disc i, the said eccentrics being situated in the jaws of the cross head as
shewn.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is.
1. In an oil feeding lifting and circulating apparatus, the employment of a piston or
plunger working in an oil chamber, to which piston a reciprocating motion may be
given by the agency of a friction eccentric when in contact with a shaft in motion,
substantially as herein fully set forth.
2. In an oil feeding lifting and circulating apparatus, the employment of two
chambers, (communicating with each other by means of an orifice,) situate one above
the other, and each provided with a ball valve, the valve in the upper chamber being
capable of changing its position alternately with relation to the valve in the lower
chamber, substantially as herein fully set forth.
3. In an oil feeding lifting and circulating apparatus, the chamber b. in the barrel a,
and chamber d in the moving piston c, ball valves f. and o. orifices p. and r. sub-
stantially as and for the purposes herein fully set forth and described in the annexed
drawings.
4. In an oil feeding lifting and circulating apparatus, the combination of the
eccentrically mounted, friction disc i. spindle j, spiral coils k., substantially as and for
the purposes herein fully set forth and described in the annexed drawings.
