Improvements in the Manufacture of Oil and Grease Cups and Oil
Syphons for Lubricating Machinery and for other Purposes.
I EDWIN LUDLOW of The Uplands Bristol Road Birmingham in the County of
Warwick Gentleman do hereby declare the nature of this Invention to be as follows:-
The bodies of the said oil and grease cups and oil syphons are ordinarily made in
one piece by casting and finished by turning filing and serowing that is the cup for
holding the oil or grease is made in one piece with the foot or base part and screw by
which said screw the said cup is screwed into the bearing or connected to the machinery
or article to be lubricated.
My invention consists in forming the body of the cup or oil syphon separate from
the connecting foot or base part and screw and making the said cup and base part and
screw and connecting them together in the manner hereinafter described.
In, making the body of the oil cup or syphon I proceed as follows:-I form from a
disc of brass or other ductile sheet metal or alloy by the ordinary drawing through
process a cup with a thick bottom the said cup having the depth and diameter of the
finished body of the oil or grease cup to be made and by a further drawing through
process I make from the thick bottom of the cup a short tubular part or stem of
reduced diameter and slightly conical. It is by means of this conical stem at the
bottom of the cup that the said cup is connected to the separate foot and screw. The
closed bottom of the stem is pierced out.
I make the separate foot and screw of a socket having on its underside a projecting
screw with an axial passage in it. The said socket or foot has a hexagonal figure
externally similar to that of the hexagonal collar of the ordinary solid foot and cup. The
passage in the screw at the base of the socket or foot opens into the seat in the said
socket or foot.

page_text: In order to secure the cup or body to the foot and screw the conical stem at the
bottom of the cup is driven into the seat of the socket or foot. The two parts are thereby
connected together.
In making oil syphons the cup of the syphon is provided with a central tube down
which the oil is drawn by threads or fibres in the said tube overhanging its edge and
dipping into the oil. This tube is fixed in the hole in the hollow stem at the bottom
of the cup by pressure or by driving it into the said hole. The metal of the stem is
thereby slightly expanded in the seat of the socket, the stem is consequently more firmly
fixed in the said seat.
The cup or body may be covered by a screw cap or by a sliding cap of the ordinary
kind.

1 EDWIN LUDLOW of The Uplands, Bristol Road, Birmingham in the County of
Warwick, Gentleman, do hereby declare the nature of my Invention and in what
manner the same is to be performed to be particularly described and ascertained in
and by the following statement:-
The bodies of the said oil and grease cups and oil syphons are ordinarily made in one
piece by casting and finished by turning, filing and screwing, that is, the cup for
holding the oil or grease is made in one piece with the foot or base part and screw by
which said screw the said cup is screwed into the bearing or connected to the machinery
or article to be lubricated.
My invention consists in forming the body of the cup or oil syphon separate from
the connecting foot or base part and screw and making the said cup and base part and
screw and connecting them together in the manner hereinafter described.
In making the body of the oil cup or syphon I proceed as follows. I form from a
disc of brass or other ductile sheet metal or alloy by the ordinary drawing through
process a cup with a thick bottom, the said cup having the depth and diameter of the
finished body of the oil or grease cup to be made and by a further drawing through
process I make from the thick bottom of the cup a short tubular part or stem of reduced

page_text: diameter and slightly conical. It is by means of this conical stem at the bottom of the
cup that the said cup is connected to the separate foot and screw. The closed bottom
of the stem is pierced out. I make the separate foot and screw of a socket having on
its underside a projecting screw with an axial passage in it.
The said socket or foot
has a hexagonal figure externally similar to that of the hexagonal collar of the ordinary
solid foot and cup. The passage in the screw at the base of the socket or foot opens
into the seat in the said socket or foot.
In order to secure the cup or body to the foot and screw, the conical stem at the
bottom of the cup is driven into the seat of the socket or foot. The two parts are
thereby connected together.
In making oil syphons the cup of the syphon is provided with a central tube down
which the oil is drawn by threads or fibres in the said tube overhanging its edge and
dipping into the oil. This tube is fixed in the hole in the hollow stem at the bottom
of the cup by pressure or by driving it into the said hole. The metal of the stem is
thereby slightly expanded in the seat of the socket, the stem is consequently more firmly
fixed in the said seat.
The cup or body may be covered by a screw cap or by a sliding cap of the ordinary
kind.
Figure 1 of the accompanying Drawing represents in elevation and Figure 2 in
vertical section an oil syphon made according to my invention. In the said
Figures 1 and 2, a is the cup of the oil syphon and 6 the connecting foot or base part;
c is the screw formed in one piece with the foot or base part 6 for connecting the oil
syphon to the bearing or other part to be lubricated; d is the central tube in the cup a
down which tube the oil is drawn by threads or fibres in the said tube overhanging its
edges and dipping into the oil in the cup a; e is the cap or cover for covering the cup a
the said cap being fixed in its place by the pin and slot at f. Or a screw cap or sliding
cap may be used."
The cup a and combined foot or base and screw b, c are made separately and connected
together in the following manner.
In making the oil cup a of the oil syphon, a disc of brass or other ductile metal or
alloy of the kind represented in Figure 3 is taken and by the ordinary drawing through
process there is formed from the said disc a cup having a thick bottom as represented
in side elevation and plan in Figure and section in Figure 5.
The said cup
Figures 4 and 5 has the depth and diameter of the finished body of the oil syphon to
be made. The cup Figures 4 and 5 is next subjected to a further drawing through
process so as to make from the thick bottom of the cup a short reduced tubular part or
stem as represented in elevation and plan in Figure 6 and section in Figure 7, in which
Figures 6 and 7 the body of the cup is marked a and the tubular part or stem at the
bottom of the cup is marked a². The said tubular stem a is slightly conical and the
bottom of the conical stem is perforated with a hole a³ of a size proper to receive the
central tube d represented separately in Figures 8 and 9.
The separate foot and screw b, c'which I use is represented in elevation in Figure 10 and
section in Figure 11. The said foot has a hexagonal figure (or other angular figure)
externally for screwing the foot into the bearing and the said foot 6 has a socket or
seat g made in it for receiving the conical bottom a² of the cup or body a. Opening
into the socket or seat g is an axial passage into which the bottom of the central tube d
is driven, or in which it is fixed.
h
The separate cup or body Figures 6 and 7 and the separate foot and screw
Figures 10 and 11 having been thus made they are connected together by driving the
perforated conical stem a² at the bottom of the cup a into the seat or socket g of the
foot as represented in the section Figure 2. The central tube d, is next driven into
the hole in the stem a² and into the passage in the foot and screw b, c. By the
driving of the tube d in the hole in the conical stem a² the metal of the said stem is
slightly expanded in the seat or socket and the said stem thereby more firmly fixed
in the said seat or socket. The lower end of the tube d is made slightly taper for
permitting it to enter the hole a³ in the bottom of the conical stem a².

page_text: In making oil and grease cups I proceed in the manner herein before described and
¡llustrated with respect to an oil syphon excepting that the central tube d is omitted.
Having now particularly described and ascertained the nature of my invention and
the manner in which the same is to be performed I declare that I claim as my invention
of Improvements in the manufacture of oil and grease cups and oil syphons for
lubricating machinery and for other purposes."
