page_text: LETTERS PATENT to Charles Harvey, of Preston, in the County of Lancaster,
for the Invention of "IMPROVEMENTS IN WASHING AND WRINGING MACHINES."
PROVISIONAL SPECIFICATION left by the said Charles Harvey at the Office
of the Commissioners of Patents on the 11th November 1879.
CHARLES HARVEY, of Preston, in the County of Lancaster.
WASHING AND WRINGING MACHINES."
"IMPROVEMENTS IN
The improvements relate chiefly to the machine for which I obtained Letters
Patent, dated the 10th of December 1872, and consist, first, in replacing the central
shaft of the tub by a short pin revolving in a boss or guide attached to the machine
frame, and serving to keep the axis of the tub in its place, a bevelled wooden ring
serving as a rolling surface upon which the driving pulley may act, the latter being
made of any suitable material, preferably iron or wood, slightly bevelled and covered
with leather or other convenient material.
Also in using two pulleys connected by a strap, chain, or rope, instead of two
spur wheels for turning the horizontal driving shaft.
Also in replacing the cylindrical washing roller by a conical roller (either &
complete or a truncated cone), having its sides converging from the circumference
to the axis of the tub, and in using rollers of the described shape for washing
purposes generally.
Also in holding the washing roller by one arm, placed at its large end, instead of
using two arms and an iron frame work, the washing roller being provided with a
boss and revolving on a stud attached to the lower end of said arm.
Also in providing the single arm with an intermediate joint and a guide for its
lower part, and in keeping down the washing roller or rollers by means of a spring
or weight instead a spring and lever.
Also in using a strong cramp bolted to the frame and serving to hold the india
rubber wringers. The Invention consists, further, in the application of an india
rubber wringer composed chiefly of two india rubber tubes and two pairs of rollers,
each tube provided with a pair of rollers working inside the tube, one roller of the
pair being larger and made to revolve without touching the other, and being set in
motion by tooth gearing or other mechanical device placed outside the frame work
and actuated by a handle which also moves the india rubber tubes. The revolution
of the latter imparts motion to the small rods or rollers inside the tubes, the large
rollers in revolving catching the cloth first, while the small ones keep the tubes
tight and straight. In some machines the two pairs of rollers are of equal size,
and the various parts may be made of metal or wood, or of both combined.

'IMPROVEMENTS IN
WASHING AND WRINGING MACHINES."
"
The improvements relate chiefly to the machine for which I obtained Letters
Patent, dated 10th of December 1872, and consist, first, in replacing the central
shaft of the tub by a short pin revolving in a boss or guide attached to the machine
frame, and serving to keep the axis of the tub in its place; also in the application
of a bevelled wooden or iron ring made fast to the bottom of the tub, and serving
as a rolling surface upon which the driving roller may act, the latter being keyed
to the horizontal shaft that works under the tub, and made of any suitable material,
preferably iron or wood, slightly bevelled to correspond with the bevelled rolling
surface of the round ring, and covered with leather or other convenient material;
also in using two pulleys connected by a strap, chain, or rope, &c., instead of two
spur wheels for turning the horizontal driving shaft and tub; also in replacing the
cylindrical washing roller by a conical or an acute angle roller, having its sides
converging from the circumference to the axis of the tub; also in holding the washing
roller by one arm, placed at its large end, instead of using two arms and an iron
frame work, the washing roller being provided with a boss and revolving on a stud
attached to the lower end of said arm; also in providing the single arm with an
intermediate joint and a guide for its lower part; and also in keeping down the
washing roller or rollers by means of a spring or weight instead of a spring and
lever, the rollers and arms being raised by a hand screw; also in using a strong
cramp bolted to the frame and serving to hold the india rubber wringers. The
Invention consists, further, in the application of an india rubber wringer composed
chiefly of two india rubber tubes and two pairs of rollers, each of the said tubes
being provided with a pair of rollers working inside the tube, and being set in
motion by tooth gearing or other mechanical device placed outside the frame work,
and actuated by a handle which also moves the india rubber tubes. The rollers are
so arranged that the clothes when passing between them are subject to three
squeezing actions before they are through the wringer, as shown by Drawings.
Also the ends of the rollers (except those with the wheels on) work in eye sockets
in the sides of the wringer, and as the clothes pass between the rollers the sides of
the wringer (which are only held top and bottom) will spring outward, and as the
ends of the rollers work in eye sockets they will open according to the thickness of
the clothes passing between them. By the above eye socket arrangement the sides
of my wringer act as spring to the machine. The various parts may be made of
metal or wood, or of both combined. And in order that my Invention may be fully
understood I will proceed to describe the accompanying Drawings. Fig. 1 is a front
view with the front of the tub removed, so that the arm, washing roller, &c., can be
seen; Fig. 2 is a side view of the same; Fig. 3 is an end view of my india-rubber
wringer, showing the position of my rollers so as to get the three squeezing actions,
also the ends of the tubes. A is the short pin for the centre of the tub; B (Figs. 1
and 2) is the bevelled ring; C (Figs. 1 and 2) is the bevelled driving roller acting on
ring B; D, D, (Figs. 1 and 2) are the two side driving pulleys; F, Figs. (1 and 2),
is the connecting band; G is the horizontal driving shaft; H (in Figs. 1 and 2) is
the tub; I is the washing roller; J is the lower part of the single arm; K is the
end of the stud connecting the arm to the roller; L is the end of the boss in the
roller; M (in Figs. 1 and 2) is the intermediate joint of the arm; N (in Figs. 1
and 2) is the guide for the lower part of the arm; O (in Figs. 1 and 2) is the spring
for keeping down the washing roller; P is the head of the cramp that holds the
wringer; (in Figs. 1 and 2) is the hand screw; R (in Figs. 1 and 2) is the
wringer; S are the wringing rollers; T is the wringing board that receives the

page_text: clothes. In Fig. 3 the arrow shows the passage of the clothes; Fig. 4 shows the
tooth gearing for the wringer; Fig. 5 is a partial front view of the wringer showing
one roller; V is the eye socket; W shows the shape of the ends of all rollers except
the two that carry the tooth-wheels. Having now described the nature of the said
Invention, and the manner in which it has to be performed, I wish it to be under-
stood that I claim as my Invention all the improvements named in the foregoing
Specification, that is to say, first, the short pin for the centre of the bottom of the
tub; second, the bevelled ring on the bottom of the tub B; third, the bevelled
driving roller C; fourth, the covering of the driving roller with leather or any
other suitable material; fifth, the two driving pulleys D, D, and connecting band;
sixth, the acute angled washing roller for cloth washing machines generally.;
seventh, using only one arm to hold the washing roller; eighth, providing the
washing roller with a boss for the stud to work in; ninth, the intermediate joint
of the single arm; tenth, the spring without lever; eleventh, the strong iron cramp
for holding the wringer. In my india rabber wringer I claim as my Invention,
first, the two india rubber tubes; second, the four rollers, one pair working in each
tube; third, the position of the four rollers so as to give three squeezing actions
during one passage of the clothes; fourth, the eye sockets for the ends of the rollers;
fifth, arranging the sides of the wringer so as to expand, and thus act as spring to
the machine.
In witness whereof, I, the said Charles Harvey, have hereunto set my hand
CHARLES HARVEY. (L.S.)
and seal, this Sixth day of May, A.D. 1880.

HENRY JAMES HARVEY.
