Improved Mechanism for Applying Pressure to and for Checking
the Concussion of the Rollers of Wringing, Mangling, and like
Machines.
I, JOSEPH LUND of 33 Argyle Street, Keighley, in the County of York,
Foreman Mechanic, do hereby declare the nature of this invention to be as
follows, that is to say :-
- It relates firstly to an arrangement and formation of means whereby
pressure is applied equally to both ends of the rollers of wringing and
like machines so that same is evenly distributed throughout the entire length.
thereof, and secondly to means whereby the concussion incident to the abrupt
ending of any thick material or fabric passing between these said rollers, is suitably
counteracted.
In accordance with my invention I arrange the screws, which operate sliding
blocks for compressing the spiral springs mounted above each end of the upper
roller's shaft, to extend through their bearings so that a bevel gear might be
fixed to each of them, and in projecting pieces fixed or formed on these bearings,
I mount a cross shaft, which extends from one screw to the other, in order that by
bevel gears being mounted upon it to be in working connection with those on the
screws and by a hand wheel at one or on both ends of said shaft when the said hand.
wheel is rotated so also will the screws be rotated and thus the springs at both
ends will be compressed simultaneously and in an equal degree.
To each of the sliding blocks operated by the screws I attach a clamping piece
which takes over the roller's shaft so that as the sliding blocks are raised by the
screws these pieces will, on a certain position being reached, raise the upper roller
from contact with the lower one.
As a covering for the bevel gears and cross shaft, an ornamental wooden casing.
in which are fitted drawers, shelves or the like or to the front of which a mirror
may be attached, might be employed.
Respecting the second part of my invention I attach bearings on each side of
the machine to carry sliding cam pieces which act under the pressure of springs.
which tend to press them with their cam surfaces into the path of motion of the
upper roller's shaft.
The dies or bushes in which this upper roller's shaft operates are also made to
have slightly inclined surfaces for contact with the cam slide above described so.
that when the upper roller is raised from the lower one by the passage between
them of any thick material or fabric the cam slides extend their greatest distance
beneath the dies in order to receive same on their descent by reason of the said
material being suddenly jerked through or from between the rollers, at which time,
by the actions of the cam surfaces, the springs acting upon the cam slides receive.
the sudden force from the roller and are overcome so that their cam slides are
moved laterally within their bearings.

Improved Mechanism for Applying Pressure to and for Checking
the Concussion of the Rollers of Wringing, Mangling, and like
Machines.
1, JOSEPH LUND of 33 Argyle Street, Keighley in the County of York,
Foreman Mechanic, 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 relates firstly to an arrangement and formation of means whereby
pressure is applied equally to both ends of the rollers of wringing and
like machines so that same is evenly distributed throughout the entire length
thereof, and secondly to means whereby the concussion incident to the abrupt
ending of any thick material or fabric passing between these said rollers, is suitably
counteracted.
In the accompanying sheets of drawings illustrative of my invention,-
Figs. 1 and 2 are respectively front and end elevations of a wringing machine
with my improved mechanism applied thereto.
Figs. 3 and 4 are front and end views respectively, of the upper part of the same
machine and show the coverings for the mechanism at this said top part.
Fig. 5 is end elevation, enlarged scale, showing certain of the parts in detail.
Fig. 6 is back sectional elevation of parts shown by Fig. 5.
Fig. 7 is sectional view on line A B of parts shown by Fig. 5 and as seen from
above.
Similar letters refer to similar parts throughout the several views.
In accordance with my invention I arrange the screws a a' (which operate the
sliding blocks bb for compressing the springs c c mounted above each end of the
shaft d) to extend through their bearings e e¹ so that the bevel wheels ffl might
be fixed to them, and in projecting pieces g g' fixed or formed on these bearings e el
I mount a cross shaft which extends from one side of the machine to the other in
order that by bevel wheels k k¹ being mounted upon it to be in working connection
with the wheels ff on the screws a a¹ and a hand or winch wheel m fixed on said
shaft when this said wheel m is rotated so also will the screws a a¹ be rotated and
thus the springs c c at both ends of the roller n will be simultaneously compressed
by the descension of the sliding blocks which force these springs against the
"dies" p p in which the shaft d of the top roller n revolves and that in an equal
degree.
To the sliding blocks 661 I attach clamping pieces which take under the
shaft d or under the hubs of the "dies" p p as shown in the drawings, so that as
the sliding blocks bare raised by the screws a a these pieces will, on a certain'
position being reached, raise the roller n from contact with the rollers for well
known purposes.
'
As a covering for the bevel gears ff and k k¹ and cross shaft h, an ornamental
wooden casing in which are fitted drawers u u', or in place of these shelves or
other similar fittings might be utilized, or to the front of this casing t a mirror t¹ or
other embellishment might be mounted thereon.
Respecting the second part of my invention I attach bearings on each side of the
machine to carry a sliding cam piece w which acts under the pressure of the spring
that tends to press it with its cam surface into the path of motion of the
❝ die " and pl.
die
These "dies" p p¹ are also made to have slightly inclined surfaces (as shown on
P in Fig. 5) for contact with the cam surface of the cam piece w so that when
the upper roller n is raised from the lower rollers by the passage between them
of any thick material or fabric, the cam slides w extend, on each side of the machine
their greatest distances beneath the dies p p¹ in order to receive same on their

descent by reason of the said material being suddenly jerked through or from
between the rollers n and s, at which time by the actions of the said cam surfaces
the springs & acting upon the slides to receive the sudden force from the roller n and
are thus overcome so that their slides w are moved laterally within their bearings v.
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 :-
1. The combination of bevel wheels, screws, sliding block, shafts and springs
arranged and formed to operate for applying pressure to the rollers of washing
and like machines substantially as herein set forth and described.
2. The arrangement and combination of parts forming the buffer mechanism of
a wringing or like machine substantially as specified.
3. The method of and means for applying pressure to the rollers of wringing
and like machines and for operating said rollers substantially as herein set forth.
