"AN IMPROVED OIL CUP WITH SYRINGE." [A communication from abroad by
Friederich Schelling, Engineer, of Hamburg, Germany.]
For engines which require oiling while working, particularly for steam engines
on ships, an oil squirt is frequently used, but as besides this squirt an oil can is
indispensable, always two apparatus are therefore necessary. By handling the oil
squirt as now used always both hands are engaged, the one to hold the squirt, the
other to set the piston at work.
}
The adjoining Drawings represent the oil can and oil squirt combined into one
apparatus, so that it can be handled with one hand only, while the other hand
remains free. This is in many cases of great importance, as the engineer or any.
other person using the apparatus can secure himself against any accident by getting
hold of any fixture with the hand remaining free, being therefore less exposed to
danger when lubricating a working engine.
In Fig. 1 a represents the oil can, forming at the same time the cylinder for, the
syringe; while b represents the piston. The piston is propelled by means of
pivoting cross bars, running diagonally to each other, and similar to the arrange-
ment of lazy tongs, also known under the name of Nürnberg shears, effecting the
forward stroke, while its back stroke is effected by the spiral spring c.
To prevent
the piston from being pushed out of the cylinder the bayonet ring d is used,
shutting it up and limiting the travel of the piston. The opening' closed by the
°

page_text: box-shaped cover e screwed over it serves to receive the oil. By a slight pressure
upon the jaws f, f¹, of the shears the oil is ejected in drops from the spout g, while
a stronger pressure makes it flow out in jets.
Fig. 2 shows the arrangement of this apparatus applied as a clyster pipe or
syringe. If the spout is conveniently curved, and the box-shaped cover e replaced
by an india-rubber pipe, which is provided with a little foot valve and screwed
over the opening, the spout can draw liquids from a reservoir or recipient placed
above it, say, for an example, on the table, and can therefore be employed as an
clysopumpe.
The particular features of the apparatus on which the claims are based consist,-
In the combination of the oil can and oil squirt into one apparatus.
In the application of the diagonally running pivoting cross bars similar to the
arrangement of lazy tongs, also known under the name of Nürnberg shears to effect
the propulsion of the piston.
In the arrangement of the apparatus to be worked with one hand only.
In the arrangement of the apparatus to effect the flow of the liquid contained in
it, either in drops or in jets.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Henry Conradi in the Great Seal Patent Office on the 28th February
1878.
HENRY CONRADI, of 8, Lower James Street, Golden Square, in the County of
Middlesex. "AN IMPROVED OIL CUP WITH SYRINGE." A communication from
abroad by Friederich Schelling, Engineer, of Hamburg, Germany.
For engines which require oiling while working, and especially for steamship
engines or other engines on ships, an oil squirt is frequently used, but as besides
this squirt an oil can is indispensable, always two apparatus are therefore necessary.
By handling the oil squirt as now used always both hands are engaged, the one to
hold the squirt, the other to set the piston at work.
The apparatus, besides being used for marine and other engines, and especially on
steamships, it is also usefully applied for land engines, shafting, gearing, pulleys,
or any kind of machinery, or its parts, wherever lubricating is required, whether
the machinery be at work or not. In the former case the apparatus will avoid the
danger to which the man by the present manner of lubricating working machinery
is exposed.
The adjoining Drawings represent the oil can and oil squirt combined into one
apparatus, so that it can be handled with one hand only, while the other hand
remains free. This is in many cases of great importance, as the engineer or any
other person using the apparatus can secure himself against any accident by getting
hold of any fixture with the hand remaining free, thus being less exposed to danger
by lubricating any machinery at work.
In Fig. 1 a represents the oil can, forming at the same time the cylindre for the
spout or for the syringe; b represents the piston, which fits the cylinder with the
requisite tightness. The piston is propelled by means of pivoting cross bars
running diagonally to each other, and similar to the arrangement of lezy tongs, also
known under the name of the so-called Nürnberg shears, effecting the forward

page_text: stroke, while its back stroke is effected by means of the spiral spring c, or any other
kind of elastic spring. To prevent the piston from being pushed out of the cylinder
either the bayonet ring d is used, shutting it up and limiting the travel of the
piston, or it is prevented and the back stroke of the piston regulated by the.
arrangement of the leaze tong levers, which becomes pressed against the jaws f, f',
of the shears. The opening shut by the box-shaped cover e screwed on serves
to receive the oil, while the apparatus or oil feeder can also be filled directly by
unscrewing the spout g. By a slight pressure upon the jaws f, f', of the shears the
oil is ejected in drops from the spout 9, while a stronger pressure makes it flowing
out in a jet.
Fig. 2 shows the arrangement of this apparatus applied as a clyster pipe or
syringe. If the spout is conveniently curved, and the box-shaped cover e replaced
by an india-rubber tube, which is provided with a little foot valve screwed over
the opening, the spout can draw liquids from a reservoir or recipient placed at any
distance or height, say, for example, on the table, and the apparatus can therefore
be applied as a clysopompe.
The arrangement of the india-rubber tube, provided with the foot valve, is shown
in Fig. 3.
The apparatus can be manufactured with or without the box-shaped cover e and
its corresponding opening. It can also be made of any kind of material, depending
for what purpose it is used, in regard to its industrial, or surgical, or medical
application.
The improvements upon which the claims are principally based consist,—
1. In the combination of the oil can and oil squirt into one apparatus.
2. In the application of the diagonally running pivoting cross bars, forming the
arrangement of lezy tongs, or so-called Nürnberg shears, which effects the pro-
pulsion of the piston.
3. In the arrangement of spiral or any other kind of springs for effecting the
back stroke of the piston.
4. In the arrangement of the apparatus to be worked with one hand only.
5. In the arrangement of the apparatus to effect the flow of the oil or liquid
contained, either in drops or jets.
In witness whereof, I, the said Henry Conradi, have hereunto set my hand
and seal, this Twenty-eighth day of February, in the year of our Lord
One thousand eight hundred and seventy-eight.
