I, WILLIAM JOSEPH HEAD, trading as the East London Machine Company, of
171 and 173, Mare Street, Hackney, in the County of Middlesex, Manufacturer,
do hereby declare the nature of this invention to be as follows;-
-
The object of my invention is so to mount the rollers of mangles and other
machines whether manually or otherwise operated and on or under such bearing
blocks so constructed and fitted that these rollers shall be more ready to "give"
or somewhat separate when something thicker than usual is presented to be passed
between them and thus no damage will be done to the machine whether thick or
thin things are passed therethrough while both thick and thin things will be
adequately treated.
To carry out this object the block it may be that under the axis of the lower
roller and it may more especially be that above the axis of the upper roller is
divided horizontally into preferably two parts which are formed and fitted to
be held in and by and to be capable of sliding between the ordinary standards of
the machine. In the proper part of this divided block is made the recess wherein
the axis of the roller can be received and the other part or parts is or are 60
formed as to be appropriate for the position or positions where it or they is or
are to be placed and for the appliances if any whereby it or they is or are to be
governed. Between the two parts is placed a spring preferably perhaps a coiled
spring in compression the ends whereof can be received in recesses made therefor
in such two parts or two or more springs may be similarly interposed. By the
spring or springs the desired "give" will be afforded and the rollers will be
allowed to separate somewhat when necessary and will immediately be brought
together again when the necessity is removed.
The meeting surfaces of the two parts may be formed as may be desired whether
complementarily or oppositely or otherwise but they may perhaps preferably be
so formed that the one part shall and must always remain in the proper relative
position vertically in respect of the other part without putting any side or lateral
or twisting strain on the spring or springs.

other Manual and other Machines.
I, WILLIAM JOSEPII HEAD, trading as the East London Machine Company, of
171 and 173, Mare Street, Hackney, in the County of Middlesex, Manufacturer,
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 my invention is so to construct and fit and arrange the bearing
blocks whereon or whereunder the rollers of mangles and other machines whether
manually or otherwise operated are mounted that these rollers shall be more ap-
propriate and convenient for use than is ordinarily the case and that the machines
shall escape from and not experience many of the evils and inconveniences at
present endured. For example these rollers so mounted on or under my bearing
blocks shall be more ready to "give" or somewhat to separate when Bomething
thicker than usual is presented to be passed between them and thus no damage
will be done in this way to the machine whether thick or thin things are passed
therethrough as is now so frequently the case while both thick and thin things
will be adequately treated. Again when these my bearing blocks are used in and
with those inangles and suchlike machines in which the upper rollers are held
down by large powerful bowed springs which springs are as is generally customary
loose or are not attached to any other parts of the machines the further great
advantage is obtained that these bowed springs will not be at all liable to fall
away or out of their required and necessary positions as is now so objectionably
very frequently the case.
In order the more clearly to explain this my invention and in what manner
the same is to be performed I refer to the accompanying drawing wherein I have
shewn side elevations of my improved bearing blocks according to two most con-
venient and efficient styles and methods of construction and formation and
arrangement.
The bearing block is horizontally or transversely divided into two parts A and B
which are duly formed and fitted in any convenient and usual or other manner
to be held and retained in and by and to be capable of sliding between the ordinary
or other standards D of the machine. In the one part the proper part A of this
so divided bearing block is made the recess E wherein the axis of the roller can
be received and held as is usual and this recess E can if desired be provided with
the ordinary brasses or liners or other devices to allow the easy and proper revolu-
tion of such axis. The other part B of this so divided bearing block is so s
constructed and formed and fitted as to be appropriate for and convenient in the
position where such bearing block is to be placed and employed and for and in
the particular uses to which it is to be applied and for and with the particular
appliances if any by which it is to be governed and controlled. Between the two
parts A and B of this so-divided bearing block is placed and interposed a suitable
spring F in compression preferably a coiled spring as is shewn in the drawing the
ends whereof can be received in appropriate recesses made therefor it may be in
both parts A and B or as is prehaps most convenient and as is shewn in the drawing
the part A may be by far the larger part of this divided bearing block and then

page_text: only one recess H is made for the spring F in such part A and in all cases the
spring F is so adjusted as normally to maintain these two parts A and B the desired
distance apart.
The meeting faces or edges of the two parts A and B of this so divided bearing
block may be formed in any manner and of any style and shape as may be ex-
pedient or necessary in each particular case. In Figure 1 I shew these meeting
faces complementarily formed or that is to say in this case a large rabbet or recess K
is centrally cut out of the meeting face of the part B whereinto enters a comple-
mentary tongue L on the meeting face of the part A in which tongue L is the
required recess H for the spring F by which arrangement as is obvious the part B
must always remain in the proper relative position in respect of the part A and
no side or lateral or twisting strain can at any time be put on the spring F. In
Figure 2 I shew these meeting faces plane and flat and in a similar manner they
may be otherwise formed as may be convenient and usual.
When it may be desired so to do each bearing block may be similarly divided
into more than two parts the supplementary part or parts being preferably similar
to the part B hereinbefore described and springs are similarly interposed between
each two adjacent parts. In all cases also more than one spring may if desired
be similarly provided between each two adjacent parts.
By the spring or springs so provided in and with this so divided bearing block
it is sufficiently obvious that the desired "give" will be afforded and the rollers
will be allowed somewhat to separate when necessary or when something thicker
than usual is being passed between them and will immediately be brought together
again when such necessity is removed and for this purpose these so divided bear-
ing blocks either may be placed above the upper roller or if and when it may be
possible and for any cause or reason expedient so to do may be placed under the
lower roller or both above and under the pair of rollers as may be desiderated
and may in any particular case be deemed to improve and render more efficient
the action and due performance of their functions in and by these bearing blocks.
When these so divided bearing blocks are to be used in and with machines such
for example as certain mangles in which the upper rollers are held down on the
lower rollers by powerful bowed springs these my bearing blocks would be placed
above the upper rollers. Then in machines where the ends of the bowed springs
enter between the standards wherein the bearing blocks slide the parts B of my
divided blocks which obviously would be the upper parts may be attached to or
may be immediately under or may constitute and form the ends of such springs M
as is shewn in Figure 1 and in machines where the ends of the bowed springs act
and bear on interposed horizontal bars the ends of which bars enter between the
standards wherein the bearing blocks slide the upper parts B of my divided blocks
may similarly be attached to or may be immediately under or may constitute and
form the ends of such horizontal bars N as is shewn in Figure 2. In any case
as is
very obvious the springs in compression of and in my divided bearing blocks
will tend to raise or lift up the ends of the large bowed spring either directly or
through the horizontal bar underneath the same when they are allowed so to do
and will therefore prevent the loose bowed spring falling away or out of its
required and necessary position as is now so objectionably common when such
spring has by long continued use or otherwise become weakened or flattened or
the like.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed I declare that what
I claim is:
1. A bearing block divided horizontally or transversely into two or more parts A
and B with a spring or springs F in compression interposed between the two ad-
jacent parts substantially as and for the purposes herein before described and
declared

page_text: 2. The divided bearing blocks for the rollers of mangles and other manual and
other machines substantially as hereinbefore described and shewn in the accom-
panying drawing.
