PROVISIONAL SPECIFICATION.
Improvements in Mangling and Wringing Machines and the like.
CHARLES JOHN GRIFFITH 29 Station Road Willesden Junction London N.W.
do hereby declare the nature of this invention to be as follows:-
In a suitably prepared frame for the reception of the rollers used for wringing
or mangling I place blocks to serve as bearings for two spindles, one above and one
below the mangling rollers, which spindles support friction discs or rollers, at or
near each end. The shafts of the wringing and mangling rollers I place on the
peripheries of the friction discs or rollers instead of in ordinary bearings as
commonly used. Latteral motion is prevented by closing the width of the forks in
the frame of machine, preferably by the insertion of plates of metal, resting
on the lower of the blocks first mentioned, and free to rise and fall in the working of
the machine, the whole being kept in position by the introduction of flanges and
washers.
On the spindle carrying the top friction rollers, I put the fly wheel for operating
the machine by means of a pinion driving a wheel fastened to the shaft of the
nearest mangling roller.
The whole can be associated with the top or under springs now commonly
used, but I prefer to adjust spiral springs under the blocks supporting the lower
friction rollers, with or without the aid of similar ones, above the corresponding
top blocks. The pressure is effected upon the rollers by hand-screws acting upon
the pairs of blocks and thus cramping the springs.
The arrangement provides mechanism for driving such machines with a small
amount of friction, and allows of a low adjustment of the working parts, placing
the whole well under the command of the operator.

CHARLES JOHN GRIFFITH 14 High Street Harlesden London N.W. late of
29 Station Road Willesden Domestic Machinery Dealer 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 :-
In the arrangement of the rollers used in mangling, wringing and such like
machines, with the view of reducing friction.
The frame of machine being provided with the usual forks for the reception of
the rollers, I place blocks or dies, to serve as bearings for spindles carrying friction
rollers or discs, of any approved diameter, to work freely on either side of the
lower bearings. The shafts of the mangling rollers 1 place on the peripheries of
the friction rollers or discs instead of in ordinary bearings as commonly used.
Lateral motion is prevented by closing the width of the fork in the frame of
machine by the insertion of vertical plates of metal resting on the lower of the
blocks first mentioned and free to rise and fall in the working of the machine in
association with the washers and flanges hereafter described.

page_text: Referring now to the drawing, F. F. (Fig. 1) is the front view of frame,
and ff. (Fig. 2) the side, shewing the fork. The mangling rollers are marked R. R.
(Fig. 1). Only a part of frame is shewn at F so as to reveal the parts inclosed.
The lower friction discs D. D. (Fig. 1) are shown with spindle half sunk in the
bearing h. Then come the rollers R. R. the lower of which works between the
inside lower disc D and a corresponding one-not shewn-at other end of machine.
I must now explain the method of furnishing the roller shafts with washers as
provided. Next the rollers at each end a tight washer A¹ (or this one may be
turned in the solid) wide enough to rather more than cover the edge of the friction
roller D. then a thin loose washer B large enough to more than span the width of
fork F to prevent endshake, then a washer-also loose-C the depth of and working
within the fork. These last two may be made in one, the larger B being a flange
to the smaller C, or they can be separate. Finally another tight washer A³ the
same as the one next the roller of machine, to work in like manner on the outside
friction disc.
The rollers, as furnished are now dropped into frame of machine, the inside pair,
and the outside pair resting on the friction discs which are carefully adjusted
immeadiately underneath, and the corresponding sets on the upper roller R ready
for the upper friction discs, d which are carefully adjusted immeadiately over. It
may be best to have one disc each side at top, and one only is shown Fig. 1.
Lateral motion (side shake) is taken up by loose pieces of metal g Fig. 2 provided
with lugs or bent edges, so as to keep in position, between which the loose
washers C. C. Fig. 1 revolve. These pieces may rest on the lower bearing / and
reach upwards a little higher than the shaft of the top roller R.
Finally the rod or shaft on which the upper friction discs, d are fixed, which rod
or shaft revolves in the bearing E similar to B and C in use on the main rollers,
and just fitting, easily, the fork of frame. These bearings are grooved so that a
rod or similar devise may bear upon them, in order to be a means of communi-
cating the pressure to the main rollers, and are flanged to prevent endshake
to the shaft.
It will be evident that all this is duplicated at the other end of the machine.
The top shaft may be used for the fly wheel operating the machine if desired, or
the fly wheel may be put on the lower roller shaft as usual. The whole can be
associated with any style of machine.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed 1 declare that what I
claim is
1. In a mangle wringer or the like roller friction discs for bearings as
described.
2. In a mangle wringer or the like, shafts provided with fast and louse washers
as described.
3. In a mangle wringer or the like the insertion of vertical pieces of metal in the
fork of machine as described.
