page_text: We, WALTER BUCHANAN, Cabinetmaker, of 317 Cumberland Street, and JOHN
MCLENNAN, Engineer, of 163 Mathieson Street, both in Glasgow, Lanarkshire, do
hereby declare the nature of our invention to be as follows:-
Our said invention has reference to an improved general construction, or
arrangement and combination of the parts, of "Wringers" or "Wringing Machines,"
which have two long small rollers, (generally covered with vulcanised india rubber),
mounted over each other, in their side frames, for compressing the water or
moisture out of wet clothes and other articles by passing them through between
the rollers; which improved machines will be more simple and durable in
construction and more efficient in their action than others heretofore in use; and
there being few metal parts about the machine, it is not so liable to cause iron
mould stains.
Our said improvements consist in making the two main side frames of the
machine of strong blocks of hard wood, having the journal bushes sunk in their
upper edge, which carries the spindle of the lower driving roller, the spindle of
which projects out beyond its journal frame at one end for having the driving
crank handle secured on it as usual by a screw and nut or other equivalent.
These
two side frames are secured together at a proper distance apart to suit the length
of the rollers, by the longitudinal angled wood bars, which guide the clothes up to
and away from the upper surface of the lower roller on each side to be compressed,
and by kneed metal brackets strongly screwed to the side blocks and ends of the
bars on their under side; although, when desired, they could have cross stays or
rods passing under these cross bars, screwed to the side blocks, when this is found
best, as for the longer roller machines. The upper moving roller, which rises and
falls to suit the thickness of clothes passed in between the rollers, is mounted over
the under roller in bush bearings checked into the under side of the upper parts or
blocks of the side frames, which would be formed of hard wood and corresponding
in width and length to the lower blocks, to which they would be secured at their
longest end from the roller journals, by metal hinges or other equivalent, so as to
rise and fall with the upper roller. One of the special improvements in our
machine consists in the mode and means of giving and regulating the elastic
pressure and rising and falling motion on this upper roller on and with its upper

page_text: bearing hinged blocks. This is effected by fitting a deep hollow cylindrical metal
socket with a bearing Blange up into each lower block frame from the under side,
as close as convenient to the bush bearings of the rollers, not to weaken these
blocks. In these sockets we fit deep helical or spiral steel springs bearing up
against their inner ends; and up through these springs and sockets and the lower
and upper moving bearing blocks, we pass long screw bolts with their heads bearing
up against the springs, so as to slide up and down in the sockets with the motion
and elasticity of the springs, but provided with a projection and groove or other
equivalent, to prevent the screws from turning round when being tightened up at
their screwed ends above the upper moving bearing block. This tightening up of
the screw bolts and springs gives any desired degree of tension on the upper roller
through the springs, and is effected by deep screw socket thumb screws screwed on
the upper end of each screw bolt, so as to bear on the top of the upper blocks
carrying the journals of the upper roller; the upper close end of each thumb screw
preventing the ends of the screws from being tightened up to such an extent as to
break the springs or unduly strain the machine. A strong metal stay is fitted
over the bolts under the thumb screws and checked with a shoulder between the
two upper moving blocks carrying the bearing bushes of the upper roller to
maintain all in steady position while moving, or rising and falling with the
different thickness of the clothes passing through the rollers. A swivelling
flat-soled bracket is mounted on the under side of each side frame block by a
strong centre bolt, these brackets having vertical and horizontal gripping jaws
with thumb pinching screws for securing the machine to the edge of a tub or table,
or other vertical or horizontal ledge near the washing or other vessels where the
.wringing is required to be performed. To prevent the necessity of the spindle of
the lower driving roller requiring to project so far as in ordinary wringing
machines, and at the same time to enable the hands and arms of the operator to
clear the projecting end of the spindle, and make the crank handle clear the tub or
ledge to which the machine is fixed, we make the crank arm with a double curved
knee outwards from the end of the machine to give the handle this greater
turning freedom.

page_text: Improvements in Wringing Machines.
We, WALTER BUCHANAN, Cabinetmaker, of 317 Cumberland Street, and JOHN
MCLENNAN, Engineer of 163 Mathieson Street, both in Glasgow, Lanarkshire, do
hereby declare the nature of our invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement in writing, reference being had to the accompanying Sheet of Drawings,
and to the letters and figures marked thereon; that is to say :-
Our said invention has reference to an improved general construction, or arrange-
ment and combination of the parts of "Wringers" or "Wringing Machines," which
have two long small rollers, (generally covered with vulcanised india rubber),
mounted over each other, in their side frames, for expressing or wringing the water
or moisture out of wet clothes and other articles by passing them through between
the rollers; which improved machines will be more simple and durable in con-
struction and more efficient in their action than others. heretofore in use; and
their being few metal parts about the machine, it is not so liable to cause iron
mould stains on the clothes wrung by it.
And in order that the nature and novelty of our said invention, and the manner
of performing or carrying our improvements into effect or practice may be properly
understood, we have hereunto appended a Sheet of explanatory Drawings, in which
the same reference letters are used to indicate corresponding parts in all the Figures
where shown.

Figure 1, is a front elevation, and Figure 2, a transverse section, taken on the
line 1 - - 1 of Figure 1, illustrating our improvements applied to a wringing
machine, while Figure 3, is a front elevation, and Figure 4, a transverse section
taken on the line 2 2 of Figure 3, showing a wringing machine fitted with
a, slightly different arrangement or modification of our improvements from that
shown in Figures 1 and 2.
------
Reing to these Drawings, our said improvements consist in making the two
out B frames of the machine of strong blocks A, A, and A¹, A', preferably of
hard wood, having metallic journal bushes A, A, sunk in the upper edges of the
lower blocks A, A, which carry the spindle 6 of the lower driving roller B, the
spindle b of which projects out beyond its journal frame at one end for having
the driving crank handle 63 secured on it as usual by a screw and nut or other
equivalent. The two side frames A, A, are secured together at a proper distance
apart to suit the length of the rollers B, B¹, by the longitudinal angled wood
bars C, C, which guide the clothes up to and away, from the upper surface of the
lower roller B on each side to be compressed, and, by kneed metal brackets C³
strongly screwed to the side blocks A. and, ends of these bars C, C, on their under
side; although, when desired, they could have cross stays or rods passing under
these cross bars, screwed to the side blocks, when this is found best, as for the
longer roller machines. The upper moving roller B¹ which rises and falls to suit
the thickness of clothes passed in between the rollers B, B¹, indicated by the arrow

page_text: in front, in Figures 2 and 4, is mounted over the under roller B, with its spindle 61
in metallic bush bearings A, A, checked into the under side of the upper parts on
blocks A, A, of the side frames A, A', and A A¹, which are formed of hard wood
and correspond in width and length to the lower blocks A, A, to which they are
secured at their longest end from the roller journals, by metal hinges a or other
equivalent as a fulcrum on which they rise and fall with the upper roller B¹.
One of the special improvements in our machine consists in the mode and means
of giving and regulating the elastic pressure and rising and falling motion on this
upper roller B¹ on and with its upper bearing lever hinged blocks A¹, A¹. This is
effected by fitting a deep hollow cylindrical metal socket o with a bearing flange
up into each lower block frame A from the under side, as close as convenient to
the bush bearings A³ of the rollers B B¹ not to weaken these blocks, and to give
the greatest lever power over the upper blocks A¹, A¹.
In these sockets c we fit deep helical or spiral steel springs c¹ bearing up against
the inner ends of the socket c; and up through these springs c¹ and sockets c and
the lower and upper moving bearing blocks A A¹ and A A¹, we pass long screw
bolts with their heads bearing up against the springs cl, so as to slide up and
down in the sockets c with the motion and elasticity of the spring c. Although
not so shown in the Drawings, these bolts c³ might be provided with a projection
and fit into a groove or other equivalent, to prevent the screws from turning round
when being tightened up at their screwed ends above the upper moving bearing
block A. The tightening up of the screw bolts c³, and springs o¹ gives any desired
degree of tension on the upper roller B¹ through the springs c¹, and is effected by
deep hand screw socket thumb screws or butterfly nuts c³, screwed on the upper
end of each screw bolt c³, so as to bear on the top of the upper blocks A¹ carrying
the journals of the upper roller B¹; the upper close end of each thumb screw o
preventing the ends of the screw bolts c from being tightened up to such an
extent as to break the springs or unduly strain the machine. In the arrange-
ment shown in Figures 1 and 2 a strong metal stay D is fitted over the bolts o³,
under the thumb screws c³ and checked with a shoulder at D¹ on the top of each of
the two upper moving blocks A¹ A¹ carrying the bearing bushes A' of the upper
roller B¹ to maintain all in steady position while moving, or rising and falling
with the different thickness of the clothes passing through the rollers B. B¹.
A swivelling flat-soled bracket E is mounted on the under side of each side frame
block A, A, by a strong centre bolt e, these brackets E having vertical and hori-
zontal gripping jaws or clamps E¹, E', with thumb pinching screws e¹, e³, for
securing the machine to the edge of a tub or table, or other vertical or horizontal
ledge near the washing or other vessels where the wringing is required to be per-
formed. In the arrangement shown in Figures 3 and 4, an additional improvement
is shown in the mode of working out the invention in so far as tightening up the
upper roller B¹ and its levers A¹, all simultaneously by one central screw F and
hand wheel F1 instead of the two butterfly hand nuts ; all the other parts
not hereinafter referred to being the same as in Figures 1 and 2. In this arrange
ment the metal stay D fitting over the bolts c³, is formed at its centre with a boss
head or socket D' into which the head of the central screw F is secured. Above
this metal stay D, a lever f is fitted over each of the bolts c³ with nuts c above
them, and project towards the central screw F, both levers being fulcrumed at f¹
on the stay D, and they are each embraced between the pronged arms of a
saddle F which slides on the screw F. The hand wheel Fl works on the screw F
above the saddle Fª and exerts through the latter and the levers f. f, any required
degree of pressure through the stay D and upper lever blocks A¹, A¹, on the upper
compressing roller B¹, to wring or express the water out of the clothes passing
through between the rollers B, B¹. To prevent the necessity of the spindle b of
the lower driving roller B requiring to project so far as in ordinary wringing
machines, and at the same time to enable the hands and arms of the operator to
clear the projecting end of the spindle, and make the crank handle 6* clear the tub

page_text: or ledge to which the machine is fixed, we make the crank arm with a double knee
curving outwards from the end of the machine to give the handle 6' this greater
turning freedom.
.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:-
First. The construction, or arrangement and combination of the parts, of wringing
machines, substantially as herein described, and distinguished in reference to and
