Improvements in Filling Cans for Filling Lamps and the like.
We, JAMES WILSON PATTERSON, residing at the Gault House, Madison
Street, Chicago, in the County of Cook State of Illinois, one of the United States
of America, Manufacturer's Agent, and JAMES HENRY MCROBERTS, of the
Village of Lucan, in the County of Middlesex, in the Province of Ontario, Canada,
Importer of Stock, 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.—
On invention relates to improvements in filling caus and the object of the
invention is to provide a simple device in which lamps or other receptacles may be
filled without raising or upsetting the can containing the oil or other liquid and it
consists essentially of a can which is provided with what is known as a single top
and means for draining the can constructed as hereafter more particularly
explained.
Fig. 1, is a perspective view of our can showing the different parts in position
ready for use
Fig. 2, is a vertical section showing the position of a lamp or receptacle being
filled from the can and in dotted lines the position of it when being drained into
the can.
In the drawings like letters of reference indicate corresponding parts in each
figure
A, indicates a can, of suitable shape and size, made of any suitable material,
preferably tin; it 18 provided with a top, B, which should be securely fastened by
This top,
any suitable means, so as to render it a tight to the top of the can.
which will call a "sink top" is preferably provided with the outside bevelled
edges, C, so that any liquid spilt into it will flow away from the sides toward the middle.
It is provided on one side with a screw thimble, D, through which the can may be
filled and with an air-tight scien cap, E, fitted to the thimble for closing the
orifice. The thimble is elevated above the upper surface of the sink-top and forms
a dam for preventing liquid in the sink-top falling into the can at that place.
F, indicates a smooth tapered thimble projecting above the smface of the
Fink-top, and communicating with the interior of the can. It is preferably made
of brass and may be secured to the top by soldering, or by any other suitable
means.
G, indicates a cylindrical piece of metal, preferably made of brass, secured to
the bottom of the sink-top by soldering of any other suitable means so that its top
is flush with the upper surface of the sink-top. It is by this means adapted to act,
as a drain and to permit the free discharge of any liquid from the sink-top through
it into the can. It is prolonged by a tube, II, which for the sake of economy is
preferably made of tin and soldered to it. This tube reaches entirely to the
bottom, but a portion of it is cut away, as indicated at, h, to allow the free passage
of liquid into it It may be securely biaced by a piece, K, fastened at one end to
ts middle part and at the other at the bottom of the sink top.
I, indicates a tube or spout, preferably made of brass and having its ends bent,
as illustrated in the drawings, nearly parallel to each other and its middle portion
united to the ends through regular curves adapted to oppose the least resistance to
the passage of liquid through them. It is adapted at one end to fit snugly
into the cylinder G, into which it may be inserted or from which it may be
withdrawn readily.

page_text: M, indicates a blow tube, which preferably consists of two metallic pieces, N,
united by a flexible middle part, O. One of the metal ends is adapted to fit
closely around the thimble, F, the blow tube may also be readily attached to or
disengaged from the thumble. When not in use it may be carried in a case, P,
provided for it on the side of the can. The can is, as usual, provided with a
bail, Q.
In operation suppose that the can is nearly filled with oil, gasoline, alcohol, or
any other liquid, the spout and the blow tube having been set in their respective
places and the screw-cap screwed into place. Then the operator by blowing
through the blow tube produces a pressure of air in the space above the liquid
within the can, which may be maintained for a short time by compressing the
flexible part of the tube. Thereupon the liquid will, at once begin to flow, under
the pressure of an, out of the spout and may be discharged without danger of
overflowing or stopping into any suitable receptacle-for instance-an ordinary
lamp (see Fig 2). All danger of overflowing is prevented, because as soon as the
receptacle is sufficiently filled the operator, by releasing the piesame upon the
flexible part of the blow tube can at once arrest the flow of the liquid through
the spout. Moreover, at the same time any portion of the liquid that remains in
the receptacle above the nozzle of the spout will be siphoned back into the can.
To drain the lamp if any sediment should collect in it, the lamp may be
gradually turned into the position shown in dotted lines in Fig. 2, when by applying
the mouth to the end of the blow tube and blowing the tube, L, will be filled and
the flow of the liquid back into the can assured.
If in filling the can or if in any other way oil should be spilled into the sink-top,
it will immediately flow back through the cylinder, G, and its extension, H, into
the can without soiling or gumming up the parts which project above the sink-top,
the cylinder and its continuation therefore act both as an outlet-opening from the
can, and a drain into it. The connection between the blow pipe and spout and the
thumble and cylinder, with which they are respectively united, should be firm and
perfectly air tight, for which reason taper joints are preferably used.
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 18-
1. A sink-top for a filling can provided with a screw capped thimble opening, a
thimble, to which a blow tube is adapted to be fastened both of said thumbles
extending above the surface of the sink-top, and a combination supply and drain
pipe ending at its upper end flush with the surface of the sink-top as and for the
purpose specified
2. In the filling can the combination with a sink-top, of a tube united to it
extending downwardly therefrom to the bottom of the can, having its upper end
flush with the sun face of the sink-top and the interior of its uppet end fitted to
receive a detachable spout, whereby it is adapted to act both as a supply pipe, and
a drain pipe, substantially as set forth.
