I, WILLIAM PHILLIPS THOMPSON, Fel. Inst. P.A., of the Agency for Foreign
Patent Solicitors, 6 Lord Street Liverpool in the County of Lancaster and
323 High Holborn in the county of Middlesex, Civil Engineer do hereby declare
the nature of the said invention for "IMPROVEMENTS IN MANGLES OR WRINGERS
(a communication from abroad by George Scott and Thomas James Baldon both
of the City of Montreal, district of Montreal and Province of Quebec in the
Dominion of Canada, Manufacturers) to be as follows:-
This invention relates to that class of laundry machines, called mangles which
are intended mainly for domestic use in smoothing linen and other similar goods,
and as a substitute for flat irons.
Its object is to produce a mangle which shall more effectually perform its
work than those at present in use, while greatly simplifying the construction and
lessening the cost of manufacture.
In all the machinery of this class of which we are aware, springs, screws,
weighted levers, and other complications exist as the necessary accompaniments of
a movable upper roller, while in this machine we are enabled, by making the lower
roller adjustable, to do away with all but the most simple devices which cannot
get out of order or prove objectionable in any way.
We construct two standards which, being properly braced, go to make up a
suitable frame in the upper portion of which is journalied a roller, and on one end
of its shaft is arranged (outside the standard) a gear wheel, which receives its
motion through a pinion which intermeshes with the said gear wheel, and receives
motion through a crank. Immediately beneath the roller above mentioned is
another roller of similar size, the spindles of which are passed through vertical
elongated slots in the standards.
A little below these slots and to one side, are arranged pins projecting inwards from
each standard, which pins fit into horizontal slots made in two levers or arms to
which is firmly fastened the table. The inner ends of these levers are curved so as
to form sockets in which rest the spindles of the lower roller, the pins aforesaid
acting as the fulcrum of the levers which support the table.

page_text: Extending across from standard to standard is a brace in the centre of which is
a socket in which fits one end of a stiff spring board which projects outwards the
same distance as the table, their outer extremities being connected by a suitable
rod the upper end of which is fixed to the table. Its lower end is screwed and
passes through the spring board and is provided with a crank out underneath the t
latter.
The operation of our invention will be as follows:-
By unscrewing or screwing the crank nut, the outer end of the table is depressed
or elevated, and acting upon the fulcrum pins and journals of the lower roller serve
to adjust said lower roller and thus to provide for unequal or varying thicknesses 1
of material passing between the upper and lower rollers, the resistance of the spring
board equalizing the pressure.
When the mangle is not in use, the spring board may be removed and the table
folded down by taking off the crank nut, releasing the rod and slightly raising
the outer end of the table so as to clear the curved ends of the levers from the ]
journals of the lower roller, and then pulling the table outwards and allowing it to
drop.
✓ Although we-have-described the above invention as applied to mangles, it must
be understood-that-the-same may be applied-to-other machines requiring an equal
and steady pressure, such for instance as wringers and the like class-of-laundry
machines.

I, WILLIAM PHILLIPS THOMPSON, 6 Lord Street, Liverpool, do hereby declare
the nature of the said Invention for "IMPROVEMENTS IN MANGLES OR WRINGERS
(a communication from abroad by George Scott and Thomas James Baldon, both
of Canada) 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 that class of laundry machines called mangles which
are intended mainly for domestic use in smoothing linen and other similar goods,
and as a substitute for flat irons.
Its object is to produce a mangle which shall more effectually perform its work,
than those at present in use, while greatly simplifying the construction and
lessening the cost of manufacture.
In all machines of this class, of which I am aware, springs, screws, weighted
levers, and other complications exist as the necessary accompaniments of a movable
upper roller, while in this machine by making the lower roller adjustable, all but
the most simple devices which cannot get out of order or prove objectionable in
any way are enabled to be done away with.
The improvements are hereinafter particularly described and specially claimed,
but for more complete comprehension of the same, reference must be had to the
accompanying drawing: in which :
Figure 1 is a side elevation of the improved mangle with table and spring board
complete.
Figure 2 is a back view of same.
Figure 3 a sectional side view with one of the standards removed.
· Figures 4, 5, 6, and 7 are enlarged detail views showing connections of levers
with standards and lower roller.
Letters similar to those herein used, indicate like parts in all the figures of the
drawing.
A, A, represent two standards which with cross-bars A¹ Aª and braces a, a, go
to make up a suitable frame,
'
Properly journalled in the upper part of the standards A A, is a roller B, on one
end of its shaft being arranged (outside the standard) a gear wheel b, driven by a
smaller gear b', carried by the cross bar A² which acts as its shaft, 6³ being a
suitable crank.
Immediately under the roller B, is another roller B' of similar size the spindles
of which are journalled in vertical elongated slots c, in the standards.
A little below these slots and to one side, are arranged pins d, projecting inwards
from each standard which pins fit into horizontal slots d', formed in the ends of
two levers or arms D, D, which carry the table C.
The inner ends of these levers or arms are also curved as at d² so as to form
sockets in which rest the spindles of the lower roller B³, the pins & acting as the
fulcrums of the levers as will be seen in Figures 3 and 5.
In a socket formed in the cross-bar A', fits one end of a stiff spring board E, which
projects outward the same distance as the table C, their outer extremities being

page_text: connected by a rod F, the upper end of which is fixed to the table C. Its lower
end is screwed as at f and passes through the spring board E, and is provided with
a crank nut G underneath the latter.
The operation of the invention will be readily understood, but it may be stated
that by screwing or unscrewing the crank nut Ğ, the levers D, D, and the table C
attached thereto are clevated or depressed and acting upon the fulcrum pins d, d,
and journals of the lower roller B¹ serve to adjust said lower roller and thus
provide for unequal or varying thickness of material passing between the
rollers B, B', the resistance of the spring board E equalizing the pressure.
When the mangle is not in use the spring board may be removed and the table
folded down by taking off the crank nut G releasing the rod F slightly, raising the
outer end of the table so as to clear the curved ends of the levers from the
roller journals, and then pulling the table outwards until the fulerum pins d, are at
the opposite ends of the slots das shown by dotted lines in Figure 5.
'
It will be obvious that the invention is applicable as well to wringers and other
like machines.
Having now particularly described and ascertained the nature of the said
"invention and in-what-manuer_the_samo is-to-be-perforined, as communicated to
mė by my foreign correspondent, I declare that what I claim-is-
1st. In a mangling machine the combination with a fixed upper roller and an
adjustable lower roller, of the arms or levers D, D, carrying the table, said arms
-being fulcrumed to the standards and provided with sockets to receive the journals
of said lower roller, substantially-as-and-for-the-purpose set forth.
2nd. The combination, in a mangling machine, of the standards A, A, an-upper-
roller having fixed, and a lower roller having adjustable-bearings therein, of the
levers D, D-the-table-supported thereby, the said levers being fulcrumed on thio
standards and provided with sockets for the support-of-the-journals of the lower
roller, whereby the space between the upper and lower journals may be increased
or diminished by elevating or depressing the front end of the table, substantially
as described.
3rd. The combination, with the frame, of the rollers B, B¹, the levers D, D,
fulcrumed on the standards, the table C, secured to the levers upon one side of the
fulcrum, and the roller B', supported upon the other side, the spring board E,,
and the rod F, connecting the said board E, with the tablo C, substantially as
described.
4th.. The combination of the standards A. A having vertical slots c, and fulcrum
pins d, with the levers D, D, having horizontal slots and carrying table C,
substantially.as and for the purpose specified.
