I, CHARLES ARTHUR ALLISON, of 52 Chancery Lane, London, in the County
of Middlesex, Patent Agent, do hereby declare the nature of this invention, (which
has been communicated to me from abroad by William Cotter Wilson, of
28 Boerum Place, Brooklyn, New York, United States of America, Medical
Electrician,) and in what mauuer the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
In the drawings making a part of this specification,
Fig. 1 is a vertical sectional view of an apparatus made according to my invention

Fig. 6 is a partial sectional view of modification:
Figs. 7 and 8 are sectional views showing certain other combinations of parts
which are also included in my invention.
This invention relates to vessels provided with means for supplying and
distributing liquid lubricants in variable quantities and commonly designated as
oilers, but which may be used for other and analogous purposes when desired.
Said invention comprises certain novel combinations of parts whereby provision is
made for the supply, from any suitable vessel or reservoir, of a fluid lubricant or
other liquid in easily and accurately controlled quantities and whereby, on occasion,
the vessel itself may be hermetically closed for carriage, laying aside, or other
purpose when not required for immediate use.
Referring first to Fige. 1 to 6 inclusive: A, is the body or oil reservoir which
contains the liquid to be distributed. The shape and size of this reservoir may be
varied according to the special purpose for which the oiler or the like is to be used.
Thus, in the drawings Figs. 1 and 2 are designed to represent largo oil-cans such,
for example, as those very commonly employed for vending illuminating oils by
the gallon and multiples thereof, although a like structure, of lesser size, may be
employed as an oiler for supplying oil to the bearings of machinery, to journal
boxes or the like. Fig. 3 shows a cylindrical reservoir more especially adapted to
general uses of an oiler where only a moderate supply of lubricating material is
required, and Figs. 4 to 6 inclusive show a comparatively small, flat and substan-
tially rectangular reservoir adapted to be carried in the pocket and especially
intended for oilers to be used with bicycles, &c.
The internal structure of the apparatus, with the exceptious hereinafter
specifically set forth, is substantially the same in all the apparatus represented
in whole or in part in the drawings. This structure, with the exception just
indicated, is represented in Figs. 1 and 2.
Within the reservoir and extended from the bottom to the top thereof is a
cylindrical sleeve, B. This sleeve is open externally at its upper end by a wide
throat as shown at, a, and at bottom by an opening, 6. The interior of this sleeve
1 DJ1

page_text: communicates with the interior of the reservoir by an orifice, c, at or near its upper
end. The upper end of this sleeve terminates in an externally threaded annulus or
annular nut, A, of corresponding internal diameter. Within this sleeve is a
conical or tapering tube C, the smaller upper end of which is open as at, d, and
the larger lower end of which is over the opening, b, in the bottom of the reservoir
so that when a passage is afforded through said tube air may pass from outside the
reservoir into the latter through the tube C and apertures f. c, when the liquid
contents of the reservoir are withdrawn. Thrust into the tube, C, through the
opening, b, is a stem, D, which for convenience of use and oporation may have
knob, e, at its outer end. When this stem is pushed inward to its limit it closes
the passage through the conical tube. When withdrawn to any extent it pro-
portionately opens said passage. E, is a movable tapering nozzle which is open at
top and bottom and which is provided with an opening, for example, as nt, fat or
near its lower end which, on occasion is brought coincident with the opening, c, of
the sleeve. This nozzle as shown in said figures is capable of a longitudinal
movement and is so formed and arranged that when moved inward it surrounds
the tapering tube, C, with its lower part snug against the circumference of the
adjacent part of the tube, and is itself enclosed within the sleeve, B, and practically
below the throat, a. With the nozzle in this position, a screw-cap, F, is screwed
upon the threaded annulus, A', and thus closes the top of the reservoir as shown in
Fig. 2; the stem, D, being thrust inward to its limit to closo the passage through
the tube, E, the reservoir is hermetically sealed and in this closed and compact
form and condition may be readily carried from place to place without danger of
spilling its contents, and as the nozzle is enclosed within it, without danger of
breakage of, or injury to, any projecting part.
'
To fit the apparatus for use and operation the cap, F, is removed, and the
nozzle is drawn outward through the throat, a, until its tapered lower end fits
anugly into the tapered or conical seat provided by the tapering interior of the
annulus as shown in Fig. 1. By this means the nozzle is frictionally 'held in
position with sufficient firmness for all practical purposes. In bringing the nozzle
to the position last described the opening, f, thereof is brought coincident with
the opening, c, of the sleeve so that communication is established from the interior
of the reservoir to the interior of the nozzle at its base or inner end. When
the nozzle is thus extended, its tapering lower part being in juxtaposition with
the relatively cylindrical internal orifices of the annulus, A, provides an annular
chamber, a', which receives all drip from the outside of the nozzle, the drip passing
down into the reservoir when the nozzle is thrust inward as explained.
In use and operation, with the nozzle extcuded as described, the apparatus is
tilted, inverted or inclined as the case may be and flow of liquid therefrom is
controlled by adjustment of the stem, b. When the passage for air afforded
through the tube, C, is slight the outflow of lubricant is proportionally slow and
may be in drops, when the capacity of such passage is increased in a liko ratio and
the outflow may lie in a continuous stream of greater or less dimensions.
In Fig. 3 the nozzle is shown with a lateral beak, 63, so that the outflow may be
directly vertically downward from the nozzle. In this fig. also, instead of applying
a cap, F, to a threaded annulus, A', as in Figs. 1 and 2, the cap is screwed upon a
screw-thread, c³, formed in the circumference of the reservoir at the upper part
thereof.
In the structure shown in Figs. 4 to 6 inclusive, the fixed nut or annulus is
indicated by reference letter, g, and is sunken so that its upper side is flush with
the top of the reservoir. The cap is substantially a nut, in this case indicated by
the reference letter, h, fast upon the nozzle and movable therewith. The latter
being capable of an axial movement is, when depressed, turned around to screw the
movable nut, h, of the nozzle into the fixed nut of the reservoir, thus closing the
latter. By unscrewing the nut, h, from this fixed nut, the former is liberated and
the nozzle may then be drawn out to its limit whereupon this apparatus may be
used as described with referènce to Fig. 1. The nozzle may have at its outer end

page_text: an elongated horizontal beak, f, so arranged that in the use of the apparatus the
beak projects beyond the sides of the reservoir thereby facilitating the use of
the apparatus for various purposes. This beak should be so arranged that when the
reservoir is closed by the nut, h, the beak will lie along the top of the reservoir
out of the way as shown in Fig. 5. In this construction the nozzle and the
tube, C, instead of being tapering throughout may be of cylindrical shape at
their upper parts as shown in Figs. 4 and 6, and of tapering form at their lower
parts. When desired a slip-cover, m, may be placed over the reservoir when in its
closed condition to conceal the beak and provide a neat external appearance to the
apparatus.
Referring now to Fig. 7 and 8: the mouth of this body is provided with a
suitable screw-thread, a'. The tapering nozzle, E, is provided at its larger or
inner end with two annular or circumferential screw-threaded nuts, 64, and c. In
pitch and character the screw-threads of each of these nuts is such that it may, on
occasion, be screwed into the screw-threaded mouth of the body, A. Botween
these nuts may be provided a milled head, a', to facilitate the turning of the nuts
into, or out of, the mouth as the case may be. The outer or smaller cad of the
nozzle E, is open as shown at, c'. Springing laterally from this same end of the
nozzle is a tubular beak, d', which serves as a second outlet from the nozzle. Fixed
within the body, A, is the tube, C, which should be of tapering form, and the lower
end, a", of which opens externally through the bottom, e', of the body while its
other end opens into the body, A, as shown more clearly in Fig. 7. Thrust into
this tube from the lower end, a", is a thin sten, D, which may have at its outer
extremity the button, b, to facilitate its manipulation. This stem may be
detachable from the tube and from the body but its functious depend upon its
co-ordination therowith. This stem, however, by reason of its detachability may
be used as a convenient implement for clearing out the oil-channel, etc., and for
other purposes. The proportions of this stem are such that when thrust inward to
its limit, it will practically close the passage through the tube. As the latter is
Romewhat tapered and narrowest at the top, a passage of greater or less capacity is
afforded through the tube when the stem is partially withdrawn, the available size
of the passage being thus capable of adjustment by the greater or less withdrawal
of the stem from the tube.
When the apparatus is to be used the parts are brought into the relative position
shown in Fig. 7, with the nozzle, E, extended outward and fixed in place by
screwing the nut, b, into the threaded mouth of the body, A. To use the apparatus
it is inclined to permit the liquid contents of the body, A, to pass by gravity to
and through the nozzle but so long as access of external air through the tube, C,
is prevented by the stem, D, such descent, by reason of external atmospheric
pressure, is impossible. The stem, D, is, therefore, partially withdrawn to permit
air to pass inward to the body, and in proportion to such access of air to replace
liquid passed from the body is the rapidity with which the liquid escapes through
and from the nozzle. For example when the passage of air inward through the
tube, C, is very much throttled or restricted the liquid will pass from the nozzle
only in drops while with increase in the rapidity aud volume of the air supply
through said tube, the outflow of the liquid is increased and may be permitted to
reach the proportions of a continuous stream. The quantity delivered and the
rapidity of its delivery being wholly under control by the simple manipulation of
the stem, D. The exit of the liquid from the nozzle may be either through the
opening, c, at its extremity or through the lateral beak, d', according to the
position in which the apparatus is held or inclined. The beak, d', is of special
advantage in supplying lubricants to oil-cups of elevated shafting as it enables the
lubricant to be readily poured into the cups by the use of only one hand of the
operator under conditions which heretofore have required the use of a force-pump
to direct the lubricant from the oil receptacle, the latter being an operation which
requires the use of both hands by the operator. The conjunction of the beak with
the opening, c', also enables oue and the samo apparatus to be instantaneously

to another, thereby economizing Dou
When it is desired to close the body against escape of its contents and to bring
the apparatus into compact form for carriage or laying aside, the nut, 6, is
unscrewed from the mouth, a', of the body, and the nozzle, inverted is thrust into
the body and passed upon and around the tube, as shown in Fig. 8, whereupon the
nut, o, is screwed into the mouth, thereby holding the nozzle firmly in its last
mentioned position, with its end surrounding the tapering surface of the tube, C.
A cap, F, which has an internal screw-thread corresponding in pitch and character
to that of the nut, b', is screwed upon the latter and thus closes and covers the base
of the inverted nozzle. The stem, D, being thrust inward to close the passage
through the tube, C, the body is hermetically sealed, and, as the nozzle is enclosed
within the body, there is no projecting part liable to be broken by vicissitude or
rough usage.
