PROVISIONAL SPECIFICATION.
Improvements in Mangling and Wringing Machines.
We ROBERT SMITH and SHEM PAGET. of The Crown Works, Keighley, in
the County of York Machine Makers, and INGHAM GOTT of Victoria Road also
of Keighley, in the County of York, Foreman, do hereby declare the nature of
this invention to be as follows
-
This invention for improvements in mangling and wringing machines has for its
object to provide improved means whereby pressure may be quickly applied to and
removed from the rollers.
In carrying out this invention the spindle of the lower roller rotates on a fixed
bearing in the frame and each end of the spindle of the upper roller is mounted in a
crosshead sliding in guides formed in the end frame in the usual manner. T'he
usual spring is arranged between this crosshead and a cap also sliding in the guides
in the end frame and operated by the screw in the usual manner.
The screw is
continued as a tail rod passing through the cap and into a covered recess in the
crosshead. The lower end of the screw spindle is fitted with a nut or pin which
when it is raised meets the underside of the cover of the recess in the crosshead to
raise it.
The screw is operated in the ordinary manner and brings the upper roller down
upon the lower roller the spring and cap descending with it, and then further motion
depresses the cap and compresses the spring and the tail rod and nut or pin on its
lower end descending into the recess in the crosshead. On raising the screw the
compression of the spring is first relieved and then the nut on the lower end of the
tail rod raises the crosshead and the upper roller.

described and ascertained in and by the following statement :-

The screw is

crosshead. The lower end of the screw spindle is fitted with a nut or pin which
when it is raised meets the underside of the cover of the recess in the crosshead to
raise it.
The screw is operated in the ordinary manner and brings the upper roller down
upon the lower roller the spring and cap descending with it and then further
motion depresses the cap and compresses the spring and the tail red and nut or pin
on its lower end descending into the recess in the crosshead. On raising the screw
the compression of the spring is first relieved and then the nut on the lower end of
the tail rod raises the cross head and the upper roller.
In the accompanying sheet of illustrative drawings :-
Fig. 1 is a part sectional elevation
Fig. 2 is a part front elevation and
-
Fig. 3 a part plan of a machine for mangling and wringing constructed according
to this invention.
The lower roller A rotates in fixed bearings B in the eud frames C and the ends
of the spindle D of the upper roller E are mounted in crossheads F sliding in
guides G formed in the end frames C. A helical spring H is arranged between each
crosshead F and a cap P sliding in the guides G and operated by screw working
in the fixed nut to put the desired pressure on the roller.
Each screw is continued as a tail rod J through the cap P and into a recess L
in the crossheads F and is fitted with a nut or pin M on its end which prevents the
end of the tail rod J from being drawn out past the cover K of the recess L when
operating the screw to relieve the pressure.
When desired to put on the pressure the screw is turned by a hand wheel N
lowering the roller E upon the roller A, the spring H and the cap P descending
simultaneously until the rollers are in contact when further motion of the screw I
depresses the cap P and compresses the spring H until it bears with the required
pressure on the crosshead the tail rod J and the nut or pin M ou its lower end
descending into the recess L in the crosshead F.
On raising the screw I the compression of the spring His first relieved and then
the nut or pin M comes against the underside of cover K raising the crosshead F
and the upper roller E.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. In a mangle in which the pressure is applied to the top roller by screws acting
through springs on crossheads forming the top bearings continuing the screws as
headed tail rods in covered recesses in the crossheads so that on said screws being
raised the heads of the tail rods come in contact with the covers and raise the
crossheads carrying the upper roller as described.
2. The improvements in mangling or wringing machines substantially as described
with reference to the drawings.
