Certain Improvements in Bearings for the Cylinder Shafts of Carding
Engines, also in Means for Adjusting the same, and in Apparatus
for Testing and Determining the Accuracy of the Adjustment.
BENJAMIN ALFRED DOBSON of Kay Street Works Bolton in the County of
Lancaster Machine Maker, do hereby declare the nature of this Invention to be as
follows:-
My invention relates to carding engines and has for its principal objects first to
provide improved bearings whereby the position of the main cylinder and its shaft can
be adjusted easily and quickly and secondly, to enable the accuracy of the adjustment
and the concentricity or true working position of the main cylinder and its shaft or
axle to be readily tested and determined.
In constructing my improved bearings I prefer to employ solid pedestals each of
which is bored out to receive an eccentric within which is fitted a second eccentric
and within the second eccentric is fitted a bush of phosphor bronze or other suitable
metal which forms a journal for the cylinder shaft. The bush is preferably kept from
turning with the shaft by having a projecting lug or ear formed with it and a screw
passing through a slot in this ear to secure it and the bush to the pedestal or other
suitable means may be employed to prevent the bush revolving. When it is necessary
to adjust the cylinder the screw which holds the bearing bush is released and one or
both eccentrics operated to alter the position of the centre as required: the screw
can then be again tightened to secure the bush in position.
A great advantage obtained by my improved bearing is that all the wear takes place
in the bush and whenever the bearing is adjusted the shaft will lie in the bed formed
by it in the bush.
Any convenient means for operating the eccentrics may be employed for example:-
The two eccentrics may be each formed with a projecting lug or ear to which is
pivoted a screw threaded stud or link passing through a swivel eye bolt or equivalent
so that by turning nuts on the studs the eccentrics may be moved to alter the position
of the bush and adjust the position of the cylinder shaft. The studs would then be

page_text: secured in position by lock-nuts and propose to enclose the nuts eyes and ends of
the studs in a box or casing and secure it by lock and key in order to prevent any
tampering with the adjusting mechanism.
Another suitable arrangement for moving the eccentrics would be to have worms
engaging werm teeth cut on the eccentrics.
In some cases it might be found advantageous to have a second bush or lining of
phosphor bronze or other suitable metal fitted between the shaft and the aforesaid
stationary bush which would in that case be made say of cast iron.
In carrying out the second part of my Invention I turn a flange on each pedestal
concentric with the hole bored for the reception of the eccentrics and bush as described
so that the periphery of this flange constitutes a circle permanently concentric with
the main cylinder as originally set. When it is necessary to adjust the cylinder shaft
to compensate for wear however occasioned I remove the driving pulleys and other
parts and place on the cylinder shaft an accurately fitted boss with two or more arms
the inner faces of which form parts of the circumference of a circle equal to the circle
formed by the periphery of the flange on the pedestal. It is obvious than when the
arms fit over the periphery of the flange on the pedestal that the cylinder shaft will
have been adjusted to its original true position. In place of making the collar to
encircle the shaft I may cut away a portion of the collar so that the apparatus can be
applied to test the concentricity of the setting or adjustment without necessitating
the removal of the pulleys etc. from the cylinder shaft. This testing apparatus can
be applied to any carding engine in which flanges can be turned on the pedestals as
described.

BENJAMIN ALFRED DOBSON of Kay Stree Works Bolton in the County of
Lancaster Machine Maker, 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 :-
My invention relates to carding engines and has for its principal objects first to
provide improved bearings whereby the position of the main cylinder and its shaft can
be adjusted easily and quickly and secondly to enable the accuracy of the adjustment
and the concentricity or true working position of the main cylinder and its shaft. or

In constructing my improved bearings I prefer to employ solid pedestals each of
which is bored out to receive an eccentric within which is fitted a second eccentric
and within the second eccentric is fitted a bush of phosphor bronze or other suitable
metal which forms a journal for the cylinder shaft. The bush is preferably kept from
turning with the shaft by having a projecting lug or ear formed with it and a screw

to adjust the cylinder the screw which holds the bearing bush is released and one or

then be again tightened to secure the bush in position.
A great advantage obtained by my improved bearing is that all the wear takes
place in the bush and whenever the bearing is adjusted the shaft will lie in the bed
formed by it in the bush.
Any convenient means for operating the eccentrics may be employed for example:---
The two eccentrics may be each formed with a projecting lug or ear to which is pivoted
a screw threa led stud or link passing through a swivel eye holt or equivalent so that
by turning nuts on the studs the eccentrics may be moved to alter the position of the
bush and adjust the position of the cylinder shaft. The studs would then be secured
in position by locknuts and 1 propose to enclose the nuts, eyes, and ends of the studs
in a box or casing and secure it by lock and key in order to prevent any tampering
with the adjusting mechanism.
Another suitable arrangement for moving the eccentrics would be to have worms
engaging worin teeth cut on the eccentrics.

In some cases it might be found advantageous to have a second bush or lining of
phosphor bronze or other suitable metal fitted between the shaft and the aforesaid
stationary bush which would in that case be made say of cast iron.

page_text: In carrying out the second part of my Invention I turn a flange on each pedestal
concentric with the hole bored for the reception of the eccentrics and bush as described
-so-that the periphery of this flange constitutes a circle permanently concentric with
the main eylinder as originally set. When it is necessary to adjust the cylinder shaft
to compensate for wear however occasioned I remove the driving pulleys and other
parts and place on the cylinder shaft an accurately fitted boss with two or more arms
the inner faces of which form parts of the circumference of a circle equal to a circle
formed by the periphery of the flange on the pedestal. It is obvious that when the
arms fit over the periphery of the flange on the pedestal that the cylinder shaft will
have been adjusted to its original true position. In place of making the collar to
encircle the shaft I may cut away a portion of the collar so that the apparatus can be
applied to test the concentricity of the setting or adjustment without necessitating the
removal of the pulleys etc. from the cylinder shaft. This testing apparatus can be
applied to any carding engine in which flanges can be turned on the pedestals as
described.
And in order that my Invention may be fully understood and readily carried into
effect I will describe the accompanying Sheet of Drawings reference being had to the
figures and letters marked thereon.
Figure 1 is an elevation and Fig. 2 an elevation partly in section of the front side
of one of the pedestals of the main cylinder shaft of a carding engine fitted with my
improved bearings. Fig. 3 is a transverse section of the shaft the bush or journal and
the two eccentrics. Fig. 4 is a side sectional elevation of the pedestal the two
eccentrics the flanged bush or journal and the shaft. Fig. 5 is a back view of the
same. Fig. 6 is a side sectional elevation showing the shaft journaled in the
improved adjustable bearing and fitted with apparatus for testing and determining
the accuracy of the adjustment, and Figs. 7 and 8 are detail views of two forms of
the boss or collar which employ in conjunction with the turned flange on
the pedestal.
Similar letters refer to similar parts throughout the several views.
Referring first to Figs. 1 to 5 a designates the pedestal bored out to receive an
eccentric within which is fitted an eccentric c within which is fitted the flanged bush d
which forms the journal for the main cylinder shaft c. In this case each eccentric
is formed with a lug or car and respectively and to each ear or e¹ is pivoted a
screw threaded stud for passing through a swivel eye bolt g secured to the
pedestal a. On the studs are nuts h by turning which the relative positions of the
eccentrics and c may be altered so as to raise or lower the bush d and adjust the
. position of the shaft as required. The bush d is kept from turning with the shaft e
as the latter revolves by means of a stud which screws into the pedestal and before
the adjusting mechanism can be operated the padlock must be released and the
casing which encloses the nuts, eyes, and ends of the studs ƒ ƒ" turned back or
removed.
Referring now more particularly to Figs. 6, 7 and 8 which illustrate the second
of my Invention.
part
Fig. 6 shows the flange a which I turn on the pedestal a concentric with the hole
bored therein for the reception of the eccentrics and the bush d so that the periphery
of this flange a constitutes a circle permanently concentric with the main cylinder as
originally set. Instead of turning the flange al upon the pedestal 1 may affix a flange
thereto such flange being concentric with the main cylinder as described. To test the
accuracy of the adjustment I employ a turned flanged boss m accurately fitted upon
the shaft e the inner face of the flange m of this boss may be either a complete circle
or part of a circle equal in circumference to the circle formed by the flange a¹ on the
pedestal and to avoid removing the pulleys and other parts not shown when adjusting
the shaft the boss m may he formed as shown in Fig. 7 or otherwise in an equivalent
manner so as to enable the boss m to be placed on the shaft and removed as required
without removing the pulleys etc. from the shaft e. It will readily be understood
that when the shaft has been adjusted to such a position that the flange m³ fits over
the flange a¹ that then the shaft will have been restored to its original setting.

page_text: My improved testing apparatus can either be employed with my improved bearings
as herein shown and described or in conjunction with any other suitable arrangement
for adjusting the position of the main cylinder shaft.
To ensure the thorough lubrication of the shaft and its bearings I propose to make
an oil cup a at the top of the pedestal and to make a hole in the bottom of the cup
and corresponding holes or slots in the two eccentrics and the bush & so as to form a
passage o (see Figs. 3 and 6) on the upper side of the shaft and I make a second
series of slots so as to form a similar passage o' on the under side of the shaft. The
oil or other lubricant from the cup a flows down the passage o on to the shaft e and
escapes through the passage o¹ into a reservoir p (see Fig. 6) formed in the foot of the
pedestal whence it may be drawn from time to time by means of a tap p². It will be
observed that the slots in the eccentrics are sufficiently long to allow the parts to be
adjusted without closing the passages o o¹.
Having now particularly described and ascertained the nature of my said Invention
and in what manner the same is to be performed 1 declare that what I claim is-
1. The improved bearing for the main cylinder shaft of a carding engine said
bearing consisting essentially of the following parts-a phosphor bronze or other
suitable metal bush forming a journal for the shaft and fitted within an eccentric which
eccentric is fitted within a second eccentric supported by the pedestal means for
operating the eccentrics to adjust the position of the shaft with the bush as required
and means for preventing said bush from revolving with the shaft as and for the
purposes herein described.
2. The combination with the pedestal a, of the bush d forming a journal for the
shaft e, the pair of eccentrics be operated by the screwed studs and the nuts or
equivalent means all substantially as and for the purposes herein described and as
illustrated by the accompanying Drawings.
3. The improved apparatus for testing the accuracy of the adjustment of the main
cylinder shaft of a carding engine said apparatus consisting of a flange concentric
with the hole bored in the pedestal for the reception of the said shaft and either
formed with or affixed to the pedestal and a boss or equivalent fitting accurately upon
the shaft and having a flange the inner face of which forms the whole or part of a
circle equal in circumference to the circle formed by the periphery of said flange as
and for the purposes herein described.
4. The combination with the flange a¹ on the pedestal a, of the flanged boss m fitted
accurately upon the shaft e substantially as and for the purposes herein described and
as illustrated by the accompanying Drawings.
5. The several constructions combinations and arrangements of parts embodying
my improvements in bearings for the cylinder shafts of carding engines and in means
for adjusting the same and in apparatus for testing and determining the accuracy of
the adjustment all substantially as herein shown and described for the purposes
specified.
