Improvements in and relating to Wringing and Mangling Machines.
I JOSEPH SMITH BURT, of 4 Waverley Terrace off Whitwale Street Glasgow,
Lanarkshire, Engineer, do hereby declare the nature of my invention to be as
follows:-
This invention has reference to and comprises improvements in the construction,
or the arrangement and combination of the parts, of wringing and mangling
machines for domestic and other nse, by which they will be rendered more efficient
and less liable to derangement than those commonly in use.
new or
The improvements consist in a new or improved method of mounting the ordinary
india rubber rollers and of regulating the pressure thereon, and of a
improved mode of and means for securing the wringer to either the sides of a wash
tub or similar utensil, or to a table for use.
According to one arrangement, capable of considerable modification, the improved
wringer would be constructed in the following manner.
Two side frames each carrying a perpendicular duplex or slotted standard
would be formed of steel, or iron cast anil galvanized, or other suitable metal,
bolted or otherwise secured together, at some distance apart, towards their lower
part by a transverse stay, or it may be by the ordinary drip board, and be held
together at top by a loose transverse bar or frame preferably of a bow form and
having projections formed at its ends to form catches which would enter and pass
through the slots in the standards and being pressed upwards would hold the two
side frames together. Each frame would be carried forward from the bottom of the
duplex standard and curved upwards terminating in a point having studs projecting
transversely on each side about the level of the axis of the upper rubber roller.
The projecting ends of the spindle of the lower roller would be carried in loose
open bush bearings supported on, preferably square, pins or standards passed into
correspondingly shaped holes formed in the lower forwardly projecting parts of the
frames.
募
A screwed nut or boss would be formed in the centre of the upper transverse bar
or frame to receive a screw actuated by a hand wheel, or other equivalent, and
carrying at its lower end a strong bow spring whose ends would enter the slots of the
side standards and press upon the end of a lever at each side of the machine
fulcrumed on the extreme forward curved up part of the frame and taking on to
the studs there, by an upwardly turned duplex hook shaped end or vice versa the
studs may be formed on the lever end.
These levers would receive the projecting ends of the spindle of the upper
rubber roller in open bearings formed in their under surface. By this arrangement
the screwing down of the screw carrying the bow spring would cause the ends of
the spring to bear upon and press down the ends of the levers on each side and
consequently press the upper rubber roller into close contact with the lower one.
The side frames would be formed flat on their under surface below the standards
so that they could rest upon a table and towards the front would have a downward
projecting piece or foot against which the one side of a tub or other utensil would
rest when used in connection with such. In order to secure the wringer in position
on either the table or the tub an angled or kneed loose foot or lever is used
preferably of a right angled form and square in section which is placed loosely in
position one on each side in a similarly shaped but larger opening or passage
leading through the lower part of the frame above the downward projecting foot.
The horizontal arm of this lever or loose foot would be formed with a stud or
projection below as a fulcrum and have one above to steady it in place in the

page_text: opening. This passage would be in open communication with the bottom of the
holes into which the before mentioned pins or standards of the open bearings of the
lower roller are inserted so that the ends of these pins would press upon the front
part near the knee of the angled foot or lever and by depressing the front part on
its fulerum would cause the downward projecting arm to press against the outside
of the tub where that was used and at same time raise the outer end of the
horizontal arm to press against the under surface of a table when that was being
used and so in either case hold the wringer firmly in position, the pressure of this
angled foot increasing in proportion to the increase of pressure conveyed through
· the bow spring by screwing down the screw in the upper transverse bar or frame.
This new or improved method of securing wringing machines in place can be
applied to ordinary forms of such machines by suitably mounting the lower rollers
in an equivalent manner to that described.
Although the improvements of this invention have been described as applied to
wringing machines it is to be understood that they are equally applicable to
machines for wringing or mangling, and fitted with rollers of wood or other
material, instead of rubber.

Improvements in and relating to Wringing and Mangling Machines.
I, PETER BURT, of Mountblue Engineering Works, Glasgow, in the County of
Lanark, Scotland Engineer, and residing at Wardie Villa, Bothwell, Lanarkshire
aforesaid, as legal representative of original applicant deceased, 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 :—
This invention has reference to and comprises improvments in the combination
of the parts of such machines by which they will be made more efficient and less
liable to derangement than those commonly in use. The improvments consist in
the method of mounting the india rubber rollers and an improved mode of securing
the wringer to the sides of a tub or a table for use.
Fig. 1 on the annexed drawing shows an end elevation of the improvments, the
wringer being composed of two side standard frames A and fitted together similarly
to other wringers with the rolls drip board and transverse bar between. The
wringer has the two slotted standards A bolted to the drip board 4 and held
together by an ordinary bow bar 7 extending from standard to standard A as in
ordinary machines at top, into which is screwed an ordinary screw 5 which bears
on top of bow spring 6 all in ordinary manner. The frames A each are extended
and carried up from bottom, forming the horn 8 having studs 9 projecting
transversely therefrom about level with axis of top roll 14. The projecting ends of
spindle of lower roller 10 work in loose open bush bearings 11 having each a pin 12
passing through a hole formed in lower part of frames A. The ends of bow
spring 6 enter the slots of standard A. and press upon the ends of a lever 13 at each
side of machine fulcrumed on extreme part of frame or studs 9 by upwardly turned
duplex hook shaped end. These levers receive the ends of spindle of upper
roller 14 in open bearings formed in under side. By this method the screwing down
of screw 5 bearing on bow spring 6 causes the ends of said spring to bear upon and
press down the ends of levers 13 on each side of machine and press upper rubber
roller 14 into close contact with lower one 10. The frames A are formed flat on
under surface and the drip board 4 fixed thereto so that the machine may rest upon
a table. Towards the front is a projecting foot 16 formed on same piece with
frame A which is formed with a bridge or hollow by the junction of the two
parts 17 & 18 shown in section. The foot 16 rests against one side of tub for

page_text: fixing thereto when in use. For securing the wringer in position on either table or
tub, a kneed loose foot or lever 18 preferably square in section is used which is
placed loosely in position one on each side of machine, in a similarly shaped but
larger opening 19 formed by the joining of parts 17 and 18 above foot 16. The
horizontal arm of lever or loose foot 18 is formed with a hole through which is
passed a stud 20 to form fulcrum for said foot which rocks thereon. The stud 20
is fixed in frame A. The pins 12 of loose bearings 11 pass through holes and press
on top of loose foot 18 at part near the knee as shown, so as to cause the downward
projecting arm 18 to press against the outside of tub when such is used and at
same time raise the outer end or arm 21 to press against under surface of a table
when such was used, so in either case holding wringer in position, the pressure of
angled foot increasing in proportion to increase of pressure conveyed through bow
spring 6 by screwing down screw 5 by handle 22.
This new or improved method of securing wringing machines in place can be
applied to ordinary forms of such machines by suitably mounting the lower rollers
in an equivalent manner to that described. Although the improvments of this
invention have been described as applied to wringing machines it is to be understood
that they are equally applicable to machines for wringing or mangling and fitted
with rollers of wood or other material instead of rubber.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is.
The particular combination of parts in the particular manner as herein before set
forth and shown.
