Firstly To improvements in the method of and means employed for securing
the round shafts or the gudgeons in wooden rollers.
In
Secondly-To improved manufacture of gudgeons for wooden rollers.
According to this invention, and referring to the first part of this invention.
securing round shatts in rollers of wood, we employ two flanges or plates; one of
such flanges or plates is passed over each end of the shaft, and to the ends of the
roller. A nut is now screwed on to a chased part of the shaft, so as to force the
flanges or plates tight up to the roller ends, and as each of the flanges or plates is
provided on its inner face with projecting pins and also an annular ring or hoop,
the pins and annular ring are forced into the wood, and acting as keys and hoop,
the shaft is held securely in the roller.
Referring now to the improved construction of gudgeon. We employ a hollow
gudgeon having a collar at one end, the other end is pointed and has around a
portion of its length a screw, say right-handed; the inner end of the gudgeon,
i.e., the end nearest the flange, is screwed or tapped, say left-handed, into which is
secured a flanged stud; the hollow gudgeon is secured into the roller, and the
flanged stud is screwed into the gudgeon, and the whole is complete. The stud of
the top rollers may have a flange or collar which is received in the brasses and
projects through, so as to connect with a lubricating chamber below.

Improvements in the Method of and Means Employed for Lubricating
Shafts, Bearings, and Gudgeons.
We, MORDECAI JEFFERSON, of Brown Royd Works, Bradford, in the County
of York, Machine Maker, WALTER WILLIAM LANCASTER LISHMAN, of Glen
Dye Works, Cornholme, in the County of Lancaster, Dyer, and JOHN CLAPHAM
of 19 St. Paul's Road, Bradford aforesaid, Stuff Merchant, do hereby declare the
nature of this invention to be as follows:-
This invention relates to improvements in appliances designed for containing oil
and lubricating shafts, gudgeons, and bearings of machinery.
According to this invention, the lubrication is effected by use of a collar or boss
fixed by nuts, keys, or otherwise on the shaft, and enclosed in brasses; the latter
are received in an outer casing, the lower portion of which forms an oil reservoir
communicating with the collar on the shaft by apertures made through the bottom
brass. Or a socket is employed enclosing a bush, the socket communicating with
an oil reservoir; the socket is closed at one end by a nut screwed against the end
of the socket. For lubricating the shaft or pulleys, a hollow boss is employed,
bored through to fit the shaft; the other end of the hollow boss is sealed by a nut
through which is a hole the size of the shaft, and the space between the shaft and
the hollow boss forms an oil chamber; a set screw through the boss, serves for filling
the oil chamber, and for cleaning out sediment.

Improvements in the Method of and Means Employed for Lubricating
Shafts, Bearings, and Gudgeons.
We MORDECAI JEFFERSON of Brown Royd Works Bradford in the County
of York Machine Maker WALTER WILLIAM LANCASTER LISHMAN of Glen
Dye Works, Cornholme in the County of Lancaster Dyer and JOHN CLAPHAM
of 19 St. Paul's Road Bradford aforesaid, Stuff Merchant, 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 :-
The object of this invention is to provide a means of lubricating the bearings of
shafts and pulleys whereby a sufficient supply of lubricant can be applied to the
bearings or pulleys to efficiently lubricate the latter for a considerable period and
whereby all dripping and waste of the lubricant is obviated and the lubricant is
protected from dust and dirt.
Such being the nature and object of our said invention the following is a
complete description of same reference being had to the accompanying drawings in
which-
Fig. 1. is an end elevation of one of our improved self lubricating bearings for

page_text: is a sectional side elevation of Fig. 1.
Fig. 3. is a side elevation of part of a shaft with a boss or collar keyed thereon,
shewn in section.
Fig. 4. is a plan view of Fig. 1. the caps and covers being removed.
Figs. 5. 6. 7 and 8. are details drawn detached to clearly shew their construction.
Fig. 9 is a side elevation of a pulley and shaft with the lubricating device
applied thereto.
Fig. 10. is a sectional side elevation of the pulley.
Fig. 11. is a sectional side elevation of the boss and collar shewing the shaft
therein.
Fig. 12. is an end elevation of the improved lubricated bearing with the pressure
applied to the top of the shaft and the bottom bearing dispensed with.
According to this invention a collar boss or swell 1 (Fig. 3) is fixed by nuts
keys or otherwise on to the shaft 2. The collar or boss 1 may be either plain at
its ends or flanged as shewn at 4 and is received and enclosed by the bearings 5. 5*
(Figs. 5 and 6) which latter are provided with flanges 6. 6. The bearings 5. 5ª are
received in the reservoir or chamber 7 in which is cast the support or projecting
part 8 having a passage 8ª in its base and the flanges 6. 6. of the bearings 5. 5
fit on each side of this support or projection 8. (Fig. 2) and are thereby prevented
from moving sideways.
The chamber or reservoir 7 is cut away to within some distance of its bottom
at 9 to allow the shaft 2 to be placed in position in the lower bearing 5 after the
latter is placed in the chamber 7. whereupon the top bearing 5ª is placed over the
collar 1. in the position shewn in Fig. 2. The chamber or reservoir 7 is filled with
oil or lubricant up to the cut away part 9 or the chamber may be filled partly with
water and partly with lubricant which will float on the surface of the water, and
lubricate the shaft or collar 1.
When the pressure is applied to the top of the shaft the bottom bearing 5 can
be dispensed with (see Fig. 12).
When the lubricant is placed in the chamber 7 the open portions 9 are closed by
the side pieces or covers 10 (Fig. 7) which are dropped down the cut away
portions, the said sides or covers being recessed at 11. for the edges 12 of the
chamber or reservoir 7. The cap 13 (Figs. 1. 2. and 8) is next fixed in position
by the thumb screws or bolts 14 to hold down the top bearing 5º.
As the shaft revolves the lubricant is drawn into the bearings 5. 5° and the
bearing part or collar swell or boss 1 is efficiently lubricated but by reason of the
collar 1 being employed, the shaft proper is kept above the level of the lubricant
so that the latter does not overflow. The passage or hole 8ª is made in the
support or projection 8 and a passage hole or holes 16 in the lower bearing 5 so
that the lubricant can readily find its way to the collar 1 by way of said holes and
the passage 8º.
Screwed plugs 21. 21 are provided at the bottom of the chamber or reservoir 7
so that the sediment dirty water or oil can be drawn off before replenishing the
supply.
When the improvements are applied to pulleys or wheels (as shewn in
Figs. 9. 10. 11) the boss 17 of the pulley is recessed so as to form a chamber 7.
A boss or collar 1 is fixed by nuts, keys or otherwise, on to the shaft 2. and
said pulley or wheel is then placed so that the boss or collar 1 is inside the
chaniber 7. after which the flange 18 is packed and secured in position by screws.
The boss or collar 1. or the inside of the chamber 7. has a recess or passage 19
formed in it, and this recess or passage is filled with lubricant, by way of the
hole 20, fitted with a plug or screw. The recess or passage 19 may be formed in
the interior of the chainber 7 instead of in the boss or collar.
As the wheel or pulley revolves the lubricant passes from the recesses 19 and
lubricates the bearing surface. A device similar to the pulley or wheel may be
made as a fixed bearing, and the shaft 2 allowed to revolve thereon.
The boss or collar may be made in halves or sections, locked, bolted or

page_text: screwed together so that it can be placed in the required position on the shaft
without the necessity of sliding it on from one or other end of such shaft.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what.
we claim is :—
(1.) In combination, a shaft, a boss, swell, or collar secured thereto, a bearing
for the collar and a chamber for lubricating material, enclosing the collar or boss
and bearing as and for the purpose described and substantially as illustrated by
the annexed drawings.
(2.) In combination, a shaft, a swell boss or collar secured thereto, a bearing for
the collar, a chamber for lubricating material enclosing the collar and bearing a
