HERBERT JOHN HADDAN, of the Firm of Herbert and Company, Patent Agents, of
67, Strand, in the City of Westminster. "IMPROVEMENTS IN LUBRICATING OIL
CUPS." A communication to me from abroad by Reuben Whitehouse Drew, of Room
14, No. 22, Saint John Street, Montreal, in the Dominion of Canada.
The Invention relates to self-feeding lubricators, the object being to save time,
labour, and material by more perfectly regulating the flow of and clarifying the
lubricant than heretofore, and consists in the formation of a reservoir or receptacle
furnished with an upper and lower neck provided with a metallic or other collar
and seat, said collar or seat, either or both of them, being arranged to support or
hold a tubular bushing or sediment protector apparatus, provided with one or more
openings for the passage of the lubricant, and fixed within said reservoir. Also
furnishing said collar with a cap, and said seat with a tapering stem tapped as a
screw or otherwise, and provided with a passage way through it. Also in the
formation of a regulating rod capable of being passed through the bushing or
sediment protecting apparatus and into the passage way of the tapering stem; fur-
nishing said regulating rod with a perforation or perforations, and a thread at or
near the base thereof, said thread being made to fit into the passage way of the
tapering stem; further, in so constructing the top of the said rod that it may enter
into the cup formed to receive it.
The improvements may be performed by making all the parts above mentioned
of metal, but it is preferred to make the reservoir of thick transparent glass, and
the other parts of brass. The openings in the bushing or sediment protecting tube
may be of any convenient size, and placed sufficiently high in the tube to prevent
sediment from entering therein. The collar and seat may be screwed on to the

page_text: neck of the glass reservoir or otherwise fixed, convenient washers being used to
prevent leakage.
The flow of lubricant from the reservoir is easily regulated by providing the
regulating rod with a tapering hole drilled from the end, and running through to
the extreme end of the rod, the rod being screwed into the passageway of the
tapering stem, which is the only opening leading from the reservoir to, say, a
journal, on which it may be fixed. The lubricant will necessarily have to pass
through this perforation. By raising or lowering the regulating rod the supply of
oil can be increased or decreased.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed by
the said Herbert John Haddan in the Great Seal Patent Office, on the 27th
June 1876.

HERBERT JOHN HADDAN, of the Firm of Herbert and Company, Patent Agents,
of 67, Strand, in the City of Westminster. "IMPROVEMENTS IN LUBRICATING OIL
Cups." A communication to me from abroad by Reuben Whitehouse Drew, of
Room 14, No. 22, Saint John Street, Montreal, in the Dominion of Canada.
My Invention relates to a self-feeding lubricator; its object is not alone to save
time and labour, but more particularly the amount of oil, the flow of which is per-
fectly regulated by an arrangement to be hereafter described.
In the accompanying Drawing Fig. 1 represents a perspective view of my
Invention.
Fig. 2 represents a sectional view showing the relative position of the different
parts when fitted together.
Figs. 3, 4, 5, & 6 represent the different parts which are made of metal.
A represents the transparent reservoir, which should be made of thick glass to
prevent breakage from any ordinary accident. This reservoir is made with two
necks, one at either end, which may be made with or without threads on them, the
same depending upon the connecting parts, whether they are screwed on or kept in
place by means of tension, in both cases washers are used to render the reservoir
tight; B represents a cap which is designed to screw into the top of a bushing or
sediment protector, Fig. 4; this protector or bushing is so arranged that its upper
portion (which is provided with a washer) shall fit tightly over the upper neck of
the reservoir. The lower part of the sediment protector is provided with a female
screw, which is designed to receive a male screw M of the seat C, which is provided
with a washer W2; thus, when the parts, Figs. 3, 4, & 5, are in place, as shown in
Fig. 2, it will be seen that the top D of the sediment protector or bushing and the
seat C are held firmly against the necks of the reservoir, which being provided with
washers W¹ & W2 there is no chance of a leakage taking place. The seat C is
provided with a tapering screw H, through which a supply passage I runs for the
purpose of carrying oil from the reservoir to the journal box on which the cup is
located.
Now the chief feature of my Invention, and the one to which I desire especially
to draw attention is, the manner in which I regulate the flow of oil from the
reservoir to the journal; this is done by means of a regulating rod E, which is
provided with a thread at its lower end, and also with a tapering hole drilled
through from the outside about 1/, or 1/, an inch from the end, and running through
to the extreme end of the rod. Now as this rod screws into the passage I, which
is the only opening leading from the reservoir to the journal, it will be seen that all
oil conveyed to the journal will necessarily have to pass-through this perforation.
It will also be seen that by raising or lowering the rod E the supply of oil can
either be increased or decreased, as, for instance, if it is desirable to increase the
flow of oil the rod is slightly raised, thus exposing more of the hole F, and conse-

page_text: quently allowing more oil to flow through the little channel leading down through
the end of the rod E. This channel I refer to will be more readily seen by referring
to the rod, as shown in Fig. 6, where it is indicated by the dotted lines. I do not
confine myself to a single hole and passage; there may be two or more, or the rod
may be provided with a shaped slot; but the arrangement shown I prefer to any
of these just mentioned. The upper end of the regulating rod E is flattened out,
and the length of the rod E is such that when the cap B is removed this flattened
end projects sufficiently to allow any one easily to turn the rod to the right or left
for the purposes before mentioned.
The bushing or sediment protector, Fig. 4, is provided with two or more holes G,
which are located almost half an inch above its lower end, and they may be of any
size sufficiently large to allow the oil to flow freely; these holes are placed opposite
to each other, and through which all oil must pass before it is conveyed to the
journal, as both ends of the bushing fit tightly against the washers W₁ and W. It
will be seen that by this arrangement no sediment is likely to enter the delicate
passage, and hole F of the rod E, which would be liable to soon choke it up and
prevent the free flow of oil.
Having described all the different parts which compose my Invention, I will now
give a general description of the manner and mode of filling, applying, and regulating
the cup. When all the parts are placed in position, as shown in Fig. 2, the cup is
ready for use, and may be applied to any journal box. To fill the reservoir A the
cap B is only required to be removed, when the oil may be introduced through the
neck D of the bushing or sediment protector. After filling the reservoir the
sediment, should there be any in the oil, will settle in the bottom of the neck on
which the seat C is fitted. The pure oil being supplied through the holes G passes
down to the bottom of the bushing to the point N, where the hole F at the bottom
of the rod E is located, passing down through the passage I of the seat H in the
direction of the arrow to the journal box. The supply of the oil will of course
depend in a measure on the suction occasioned by the journal while in motion, the
same being governed by the rapidity with which it runs. When applying these
cups to spindles which run at a very high rate of speed it may be found desirable to
cut several shaped slots in the lower portion of the rod E to supply a sufficient
quantity of oil to fill the demand. I propose to make the metallic portion of my
cup of brass, although they may be made of any suitable material. The reservoir Å
being rendered perfectly tight by the leather or any other similar washer W and W*
the cup may be applied to loose pulleys.
In the claim which I now make I desire to secure as a part of my Invention the
bushing, Fig. 4, although the cup can be constructed without it, and the upper and
lower parts so arranged that they may be attached directly to the necks of the
reservoir A by means of screw threads or cement.
Having thus described my Invention what I claim as new and desire to secure
by Letters Patent is, in a lubricating cup for the purpose of automatically feeding a
journal with oil as required the glass reservoir A, cup B, bushing D provided
with openings G, seat C, tapering stem H, with passage I, regulating rod E, with
perforation F and washers W¹ and Ws, the whole arranged and constructed substan-
tially as and for the purposes herein specified.
In witness whereof, I, the said Herbert John Haddan, have hereunto set my
hand and seal, this Twenty-fourth day of June, in the year of our Lord One
H. J. HADDAN. (LS.)
