Improvements in Adjustable Bearings for Rotatory Spindles, Axles,
and Shafts.
We, JAMES CHARLES DALMAN, of Chunk Foundry, River Street, Deritend, in
the City of Birmingham, Ironfounder and Merchant, and EDWARD JOSEPH BLINCOE,
of 16 Highgate Place, Moseley Road, Birmingham aforesaid, Foreman Machinist do
hereby declare the nature of this invention to be as follows:-
This invention relates to the bearings or double bearings of spindles, axles and
shafts, such for example, as those employed in brass-workers lathes, polishing and
buffing machinery, fans and other machinery and appliances, fitted with high or other
speed driven and driving spindles, axles, and shafts.
In carrying out our invention, in connection with a polishing machine, commonly
called a spindle, we mount the buffs, bobs, or polishers, upon the ends of the spindle,
as usual, and support the said spindle at near its ends, or at points between the bobs
or polishers.
The suppor consists of arms, or branches, directed from a casting or head-stock,
and with the upper parts of the said arms, axially pierced, or made hollow, wherein an
adjustable and inside coned bearing, longitudinally passes.
The enlarged taper of the inside coned bearings, are directed inwardly, whilst pin
fast to the spindle, surrounded by the bearings as aforesaid, are coned collars, of the
inside figure or taper of the said bearings; so that the coned collars rotate within the
coned bearings, which are adjustable longitudinally inwardly.
Thus, the spindle, is provided at suitable distances apart, with tightly fitted coned
collars, which rotate within the inside cones of adjustable hearings, whose outside
circumferences, are uniform in diameter, and fit within concentric holiows or bearing
holes, made through the ends of the branches of a casting, alike unto a head-stock.
Fast and loose pulleys, are carried on the middle of the spindle, between the
bearings.
When adjustment consequent upon wear, is required, it is only necessary to force
inwardly the adjustable bearings, when the necessary adjustment is acquired.
The coned collars inay be forged, or made in one piece with the spindle.
The adjustable bearings, may be adjusted within the hollow ends of the supporting
framing by screws, or wedge cottars, and further, the contact bearing surfaces may
be lubricated by oil cups, applied in manners suitable to the machine.
From the above description, it will be gathered that the inside coned bearings,
which lie within the hollows of the fixed framing, are incapable of rotation, but
admit of adjustment longitudinally.
The support or base, may be in the form of a pedestal, with bed plate, or in the
form of a hanger.
The application of our invention, to single bearings and other machinery appliances
for various purpose, differs in no essential respect to that of a polishing spindle or
lathe as aforesaid.

Improvements in Adjustable Bearings for Rotatory Spindles, Axles,
and Shafts.
We, JAMES CHARLES DALMAN of Chunk Foundry, River Street, Deritend, in
the City of Birmingham, Ironfounder and Merchant, and EDWARD JOSEPH BLINCOE
of 16 Highgate Place, Moseley Road, Birmingham aforesaid, Foreman Machinist, 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 :-
This invention relates to the bearings, or doublé bearings, of spindles, axles, and
shafts, such for example as those employed in brass-workers lathes, polishing and
buffing machinery, fans, and other machinery and appliances, fitted with high or other
speed driven and driving spindles, axles, and shafts.
In carrying out our invention in connection with a polishing machine, commonly
called a spindle, we mount the buffs, bobs, or polishers, upon the ends of the spindle,
as usual; and support the said spindle at near its ends, or at points between the bobs
or polishers.
The support consists of arms or branches, directed from a casting or head-stock,
and with the upper parts of the said arms, axially pierced or made hollow, wherein
an adjustable and inside coned bearing, longitudinally passes.
The enlarged taper of the inside coned bearings, are directed inwardly, whilst pin
fast to the spindle, surrounded by the bearings as aforesaid, are coned collars, of the
inside figure or taper of the said bearings; so that the coned collars rotate within
the coned bearings, which are adjustable longitudinally inwardly.
Thus, the spindle is provided at suitable distances apart, with tightly fitted coned
collars, which rotate within the inside cones of adjustable bearings, whose outside
circumferences are uniform in diameter, and fit within concentric hollows or bearing
holes, made through the ends of the branches of a casting, alike unto a head-stock.
Fast and loose pulleys are carried on the middle of the spindle between the
bearings.
When adjustment consequent upon wear, is required, it is only necessary to force
inwardly the adjustable bearings, when the necessary adjustment is acquired.
The coned collars u:ay be forged, or made in one piece with the spindle.
The adjustable bearings, may be adjusted within the hollow ends of the supporting
framing, by screws, or wedge cottars, and further, the contact bearing surfaces may
be lubricated by oil cups, applied in manners suitable to the machine.
From the above description, it will be gathered, that the inside coned bearings,
which lie within the hollows of the fixed framing, are incapable of rotation, but
admit of adjustment longitudinally.
The support or base, may be in the form of a pedestal, with bed plate, or in the
form of a hanger.
The application of our invention, to single bearings, and other machinery
appliances for various purposes, differs in no essential respect to that of a polishing
spindle or lathe as aforesaid.
Figure 1 of the accompanying drawings, represents partly in vertical section, and
partly in elevation, a polishing lathe, provided with adjustable coned bearings,
constructed and arranged according to my invention.
The right hand side of the said lathe, is shown wholly in section, but with the
spindle and its cone, in elevation. The other side of the lathe, is shown somewhat
alike to the other side, but with the she-coned bearings, which take within the head of
one side of the appliance, in elevation.
The he-cones upon the spindle, are alike unto coned collars, which move with the
spindle, whilst the adjustable and she-cones, are brought up to the bearings of the
he-cones, by inward and longitudinal displacement.
Figure 2 represents a complete horizontal section of the said lathe, through the

page_text: heads, and she-cone bearings, leaving the spindle and its cones, and also the fast
and loose pulleys, in elevation.
Figure 3 represents a transverse section, through one of the heads of the lathe,
and which section, is taken upon the dotted lines A B, Figure 2.
Figure 4 shows the spindle, with its he-cone, or cone collar (which is made fast
with it) and the adjustable she-cone, in section.
Figure 5 shows an end view of the she, and adjustable cone, looking towards the
mouth of it.
Figure 6 represents a horizontal section of the head of a lathe, as in Figure 2, but
provided with means of adjusting the she-cones, up to their bearings upon the he-
cones, which is accomplished by recessing the outsides of the she-cones with inclined
planes.
The same letters of reference indicate corresponding parts in the several figures.
a is a spindle, provided with coned collars, or he-cones b, made fast upon it, and
adapted to work within longitudinally adjustable she-coned bearings c, consisting of
inside coned cylinders or blocks, taking within the hollows d³, of heads, surmounting
the upper ends of upright brackets or housings &, of a framing d, supported by a
base d. The adjustable she-coned bearings c, are secured in their adjusted positions,
by screw-pins e, and lock nuts e³:
The bearings are supplied with lubricant, through oil cups f, with channels f³,
directed to the bearing surfaces.
is a loose pulley, turning freely on the spindle, and g³ is a fast one.
To adjust the she-coned bearing c, upon the coned collars or he-cones b, loosen the
screw nuts e, and lock nuts e, then force inwards the said bearings, which are then
affixed in position, by the clamping screw nuts e, and locking nuts e² being screwed
home.
The buffs, bobs, or polishers, are secured upon the ends of the spindle as usual.
By providing high driving, driven, and other spindles, with coned bearings, and
adjuncts as described, considerable advantage is obtained, besides minimising wear
and tear of them.
In Figure 6, the adjustable and sleeved coned bearings c, have inclined recesses c³,
sank within them, wherein the points e³, of the clamping screw pins e, take, and by
the forcing home of the said screw pins, automatic adjustment of the said coned
sleeves, is obtained, upon the collar cones within them.
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 is :-
.
First Providing the spindles, axles, or shafts, of polishing and other machinery
including lathes, with adjustable coned bearings, consisting of fixed collar cones b,
working within adjustable or she-cones c, taking within the hollow heads of the
housings or framing of the said machinery, or lathes, substantially as described and
set forth.
.
Secondly In adjustable coned bearings, consisting of made-fast he-coned
collars, working within she-coued bearings, made separate from, or in one piece with,
the uprights or framings of a machine, all constructed, arranged, and working,
substantially as described and set forth.
Thirdly The combination with adjustable sleeve coned bearings, of an inclined
sided recess c, wherein the point of the adjustment screw or like device, takes, for
bringing the said coned sleeve up to its bearing, upon a collar cone, as described and
set forth.
