SAMUEL BARRATT, Engineer, 32, Duxbury Road, Leicester. I do hereby declare
the nature of this invention to be as follows:-
My invention relates to wringing or mangling machines on which two rollers
are placed one over the other and are brought into contact by pressure been
placed on the necks of the rollers. The rollers are fixed into a frame work and
motion is imparted to the rollers by means of handle and wheels or pullies if
require for power.
For the purpose of imparting pressure to the rollers for wringing or smooth-
ing linen and the like, I connect the bearings together in a manner so that the.
whole of the pressure is imparted to the rollers, by means of pressure brought to
bear solely against the necks, which holds the rollers in position; or in a man-
ner that only inward pressure is exerted to hold the pressure on the rollers.
To obtain this, I insert a metal rod or rods through the bearings, on one end of
which is a head and on the other end a nut. place a spiral spring or fix other
means of giving pressure on one end of the rods and the rods are passed through
holes in the bearings carrying the rollers and through metal plates resting
loosely against the bearings which is held loosely with the rods. In this plate
or nut is inserted through its centre a screw, at the other end of which is a
hand wheel or other kind of handle, which when turned is pressed against the
bearing holding the roller which has the means of tightening the spring, when
required to give more pressure. In some instances I make the iron plate into
the bearing and continue the same plate forward in a round form with a hole
through and continue the rod which draws against the spring at the opposite
end. Through the extended part of the bearing and on the end of the rod, place
a hand wheel or handle with a thread in it, on the rod which when turned is
the means of tightening the spring, by drawing the rod against the spring and
thus shortening the space between the handwheel and the spring. In some
instances instead a spiral spring, I use a spring preferably bow-shaped, which
is placed across the machine under the rollers, the ends of which I suspend on
the rods which pass through the bearings or I place the ends of the springs on a
plate held at both ends with the rods, on which I place the bow spring and
above the how spring, extending across the machine I use a metal stretcher which
at both ends presses against bottom bearings of the rollers, in the centre of
this stretcher is a threaded hole, through which is placed a screw, which when
turned, presses against the bow spring, thus by this operation giving pressure
against the bearings of the roller. In some instances where two spiral springs
are used instead of imparting pressure to the rollers by a screw through the
metal plates instead of the plates, I place above each of the two top bearings a
groved pulley, round which the rods which carry the spring pass and through
the pullies I place a rod, which extends across the machine and ou each side of
the pullies I place a boss. The hole through the pulley passes as well through

page_text: the bosses. These bosses rest on two parts of the bearings, which are somewhat
extended. The holes in the pullies and bosses not been in the centre, when the
rod which passes through them and which is fastened in the pullies is turned it
has the effect of raising or lowering the rods passing round the grove pulley,
thus tightening or slackening the spring according to requirements. By thus
using these means of giving pressure to the rollers by pressing against the
bearings direct, instead, as usually is the case, using the framework of the
machine to press against or receive the pressure of the spring
It will be seen
that the frame-work of the machine is not liable to be broken as hitherto has
been the case and therefore lighter frame-work may be used. The bearings of
the rollers are carried in an iron frame work. The stand to which I attach. This
frame I make usually of wood consisting of two upright ends, jointed into feet.
Across the bottom of the machine, I place a cross-bar of wood which is bolted
both to the upright ends and feet of the machine. At the extreme ends I place a
piece of iron which bolts to the feet at the sides, also to the sides of the upright
end, thereby imparting rigidity to the frame works, where wood is not used the
whole of the frame work may be of metal with the improved means of bringing
pressure on the roller bearings resting in the same. In some instances instead
of the springs been placed below the bearings the springs are placed above and
rest on the bearings and are pressed against the same by a screw and handle.
The rods passing through the necks and springs as here to fore.
In some instances in addition to the two rollers, I use a felted board, between
the rollers on this board I place the work to be smoothed and in this arrange-
ment may have for convenience the bottom roller in several parts, in this in-
stance to give pressure I use an iron bar with two gradients upon it, which press
upon the frame holding the bottom roller. The pressure may be increased or
lessened by the bar having on its edge at one end teeth which are engaged into a
worm this worm being operated by a hand wheel fixed to the same.

SAMUEL BARRATT, Engineer, 32, Duxbury Road, Leicester, 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, that
is to say:
It consists in the improvements and arrangement of parts in connection with
the construction of wringing and mangling machines in which two rollers are
placed one over the other and are brought together by pressure. For the purpose
of describing the same I hearwith have appended sheets of drawings, illustra-
tive thereof to which by figures and letters reference is made in the following
description.
Fig. 1 is a front elevation of a machine made in accordance with this invention.
Fig. 2 is a part sectional end elevation showing a portion of the parts illus-
trated by Fig. 1.
Fig. 3 is another sectional end elevation showing a slightley altered method
to Fig. 2.
Fig. 4 is a part back elevation showing another meathod of arranging the.
spring or springs and pressure arrangment.

in place of spiral spring.
Fig. 6 shows another part elevation where in another meathod of putting on
pressure to the roller is shown.
To obtain the object of this invention the well known kind of wood rollers are
used with shaft through them or in some instances for giving greater smooth-
ness metal rollers may be used. The rollers A are mounted in brackets B carried
on a frame work or suitable stand C which frame work is joined together by
cross rail D fastened by bolts E and iron T pieces F at each end of the frame or
stand gearing wheels G with handle H for turning the rollers, or pullies may
be used for larger machines. Attached in the brackets B are necks I in which
the shafts of the rollers A are inserted, the top neck I is a loose neck over
which a block J is placed, this block J as two holes through which are inserted
bolts K one of each of the bolts pass through the necks J on each side of roller
shaft L, and pass through the springs M on the ends of the springs is an iron
cap N through which the bolts pass, and nutts are placed on them to hold cap
against springs M, through the block J is inserted screw O, to which hand
wheel P is attached, it will be seen in Fig. 3 that only one bolt K is used, the
boss on hand wheel P is made longer so as to take the place of the block J.
Fig. 4 shows a spring Q, in another position, this spring presses against
bar K, pressure is brought to bear on this spring by screw which is threaded
through bar S this screw is turned by hand wheel P the ends of bar R resting
on bolts M.
Fig. 5 shows another kind of spring T which rests upon bar U pressure is
brought to bear on this spring by screw which is threaded through bar V, the
ends of bar U resting on bolts M.
In Fig. 6 another method is used to give pressure to the rollers by having a
metal bar W, with inclined wedge shaped parts upon it, this bar is
pressed between block and neck I on its shaped parts X, which
is done by means of a worm W, engaging into V placed on bar T, and by this
means draws against spring K this bringing. together the rollers A, A, for the
purpose of giving the desired pressure, the same arrangement I also use beneath
the rollers instead of above when more desirable to do so.
It will be seen by these various arrangements of applying pressure to the rollers
that the frame work of the machine is relieved of all strain upon it, the pressure
being applied only on the necks of the rollers, by this means, I am enabled to
build the frame work C of lighter meaterials and I preferabley use wood for the
purpose, in some instances I place the springs M as shown on Fig. 2 and Fig. 3
in the same position as on Fig. 4 and have bar R pressing on them actuiated by
screw and wheel as shown on Fig. 4.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare what I
claim is:
The method of bringing the pressure on to the rollers A A, by the various
methods as shown in the drawings attached and referred to in description,
whereby pressure is imparted against the necks of the rollers, A A, in such a
manner that all strain is taken off the frame work of the machine.
Also the arrangement of the construction of the frame work of the machine
and the whole or any of the parts as shown, by the various drawings, attached
and by the various combinations as described.
