IMPROVEMENTS IN WiQNTVA AND DINAINA AND MA PROVISIONAL SPECIFICATION
Year: 1875

page_text: LETTERS PATENT to Joseph Summerscales, of Keighley, in the County
of York, Machine Maker, David Marks, Foreman Mechanic, and
William Smith, Foreman Joiner, both of the same Place, for the
Invention of " IMPROVEMENTS IN WiQNTVA AND DINAINA AND MA
PROVISIONAL SPECIFICATION left by the said Joseph Summerscales
David Marks and William Smith at the Office of the Commissioners
of Patents, with their Petition, on the 12th June 1875.
Wc, JOSEPH SUMMERSCALES, of Keighley, in the County of York,
Machine Maker, DAVID MARKS, Foreman Mechanic, and WILLIAM
SMITH, Foreman Joiner, both of the same Place, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN WASHING AND WRINGING
AND MANGLING MACHINES," to be as follows:-
-

page_text: of the dolly spindle a pinion or toothed wheel. Oscillatory motion is
imparted to this wheel and spindle by means of either another toothed
wheel (or which we prefer to use) a segment of a wheel, the centre of
which works on a pin or fulcrum attached to the side of the washing
bowl or vessel. The arm or lever to which the segment is attached is 5
continued beyond the fulcrum, and the end recessed to receive a thread
or feather formed on a cross shaft, which may receive its motion either
directly or by intermediate gearing from the hand wheel. This thread
or feather before mentioned is formed obliquely on the shaft, being half
right and half left handed, so that the end of the lever within which it 1
works has an oscillatory motion imparted to it which is conveyed to
the "dolly" by the segment wheel and pinion, the extent of the partial
revolution performed by the dolly being variable according to the
obliquity of the feather, and the proportion between the two arms of
the lever carrying the segment wheel. By causing the end of the lever 1
to work in a suitably formed cam groove the same result will be
obtained.
Secondly. In the employment of an improved "cap" or top bearing
for the dolly spindle, which we construct in two parts, one part fitting
into a dovetailed slot formed in the other part. By this arrangement
the removal and replacement of the "dolly" is facilitated.
Thirdly. In an improved arrangement of levers for applying weight
to the rollers of wringing machines. Hitherto the fulcrum of such
levers has been placed at one end nearly close to the centre of the
rollers, and the weight or spring at the other end of the lever at a
greater distance from the centre of the rollers. In consequence a slight
motion or lift of the top roller becomes a considerable one at the end of
the lever, to allow of which it is necessary to use springs of great
flexibility, such springs having necessarily to be made of steel. By our
arrangement we place the fulcrum at a point intermediate of the two
ends of the lever, and much nearer the weighted or resisting end than
the centre of the rollers where the force is applied. Thus the motion of
the roller is diminished in extent at the resisting end where it is very
trifling. To resist this slight motion we employ cast-iron springs, and it is
the possibility afforded for substituting cast-iron springs or springs made
of steel that constitutes one of the merits of this part of our Invention.

filed by the said Joseph Summerscales, David Marks, and William
Smith in the Great Seal Patent Office on the 11th December
1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOSEPH
SUMMERSCALES, of Keighley, in the County of York, Machine Maker,
DAVID MARKS, Foreman Mechanic, and WILLIAM SMITH, Foreman
Joiner, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twelfth day of June, in the year
of our Lord One thousand eight hundred and seventy-five, in the
thirty-eighth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto us, the said Joseph Summerscales, David
Marks, and William Smith, Her special licence that wo, the said
Joseph Summerscales, David Marks, and William Smith, our executors,
administrators, and assigns, or such others as wo, the said Josoph
Summerscales, David Marks, and William Smith, our executors,
administrators, and assigns, should at any time agree with, and no
others, from time to time and at all times thereafter during the term
therein expressed, should and lawfully might make, use, exercise,
and vend, within the United Kingdom of Great Britain and Ireland,
the Channel Islands, and Isle of Man, an Invention for " IMPROVE-
MENTS IN WASHING, WRINGING, AND MANGLING MACHINES," upon the condition
(amongst others) that we, the said Joseph Summerscales, David Marks,
and William Smith, our executors or administrators, by an instrument
in writing under our, or their, or one of their hands and seals, should
particularly describe and ascertain the nature of the said Invention,
and in what manner the same was to be performed, and cause the
same to be filed in the Great Seal Patent Office within six calendar
months next and immediately after the date of the said Letters Patent.
NOW KNOW YE, that we, the said Joseph Summerscales, David
Marks, and William Smith, do hereby declare the nature of our said
Invention, and in what manner the same is to be performed, to
be particularly described and ascertained in and by the following
statement, and accompanying Sheet of Drawings (that is to say) :-

oscillatory motion to the "dolly." For this purpose we attach to the
top of the dolly spindle a pinion or toothed wheel. Oscillatory motion
is imparted to this wheel and spindle by means of either another toothed
wheel or (which we prefer to use) a segment of a wheel, the centre of
which works on a pin or fulcrum attached to the side of the washing
bowl or vessel. The arm or lever to which the segment is attached is
continued beyond the fulcrum, and the end recessed to receive a thread
or feather formed on a cross shaft which may receive its motion either
directly or by intermediate gearing from the hand wheel. This thread
or feather before-mentioned is formed obliquely on the shaft, being half
right and half left-handed, so that the end of the lever within which it
works has an oscillatory motion imparted to it which is conveyed to the
"dolly" by the segment wheel and pinion, the extent of the partial
revolution performed by the "dolly" being variable, according to the
obliquity of the feather, and the proportion between the two arms of
the lever carrying the segment wheel. By causing the end of the lever
to work in a suitably formed cam groove, the same result will be
obtained.
Secondly. In the employment of an improved "cap" or top bearing
for the "dolly" spindle which we construct in two parts, one part fitting
into a dovetailed slot formed in the other part. By this arrangement
the removal and replacement of the "dolly" is facilitated.
Thirdly. In an improved arrangement of levers for applying weight
to the rollers of wringing machines. Hitherto the fulcrum of such
levers has been placed at one end nearly close to the end of the rollers,
and the weight or spring at the other end of the lever and at a greater
distance from the centre of the rollers. In consequence a slight motion
or lift of the top rollers becomes a considerable one at the end of the lever,
to allow of which it is necessary to use springs of great flexibility. By
our arrangement we place the fulcrum at a point intermediate of the
two ends of the lever, and nearer to the weighted or resisting end than
the centre of the rollers where the force is applied. Thus the motion of
the roller is rendered less perceptible at the resisting end of the lever,
and the springs are not subject to such great inflexions.
In order that this Invention may be more fully understood we herein;
give reference to an accompanying Sheet of Drawings illustrative thereof.
The same letters refer to the same parts in cach Figure.

page_text: Fig. 1 is side elevation of such parts of a combined washing and
wringing machine as are necessary to illustrate our improvements;
Fig. 2 is a plan view of same, and Fig. 3, a front elevation; Figs. 4
and 5 are details of "cap" or top bearing for "dolly" spindle.
For giving oscillatory motion to the "dolly," we employ a pinion A
on the top of the "dolly" spindle. This pinion gears with the segment
wheel B working on a stud C attached either to the top of the washing
bowl, or to a rail fixed to the sides of a machine. The arm of the
segment wheel continued beyond the fulcrum terminates in a " notch,"
within which is received the thread or feather D on the boss & mounted
on the cross shaft E. This cross shaft receives rotary motion cither by
change gearing from the hand, wheel F as shewn in the Drawings, or it
may be worked directly if preferred. Our improved "cap" or top
bearing for the “ dolly" spindle is indicated by the letters G, G¹. The
part G is attached to a rail H fixed to the framework, and is formed
with a dovetailed slot into which the part G¹ slides. The two parts are
shewn in detail at Figs. 3 and 4; Fig. 3 represents them separate, and
Fig 4 when joined together. The "dolly" J works on the pointed
stud K at the bottom, and when released from the top bearing can be
easily removed and replaced. Our arrangement for applying pressure to
the rollers of wringing machines is shewn in Fig 1. L is the lever attached
to the framework by the fulcrum pin or stud M, the end L' pressing
upon the top of the roller shaft N. The pressure is communicated to
the lever L by rod P and spring Q. The spring may be placed
towards the bottom of the machine, but the pressure being exerted
upwards we prefer to place it nearer to the lever, as shewn in the Drawing.
Having thus described the nature of our said Invention and shewn by
Drawings how the same may be performed, we would have it understood
that we do not confine ourselves to the precise details of form or
mechanism herein shewn, as the same may be varied, but what we claim
is,-
Firstly. The use of the segment wheel, pinion, and thread or feather,
or other mechanical equivalent for giving oscillatory motion to tho
"dolly," substantially as herein shewn and described.
Secondly. The use of a "cap" or top bearing for the "dolly" spindle
constructed in two parts as herein shown and described.

page_text: Thirdly. The arrangement of levers and other apparatus for applying
weight to the rollers as herein shewn and described.
In witness whereof, I, the said Joseph Summerscales, for and on
behalf of myself and the said David Marks and William Smith,
have hereunto set my hand and seal, this Ninth day of December,
in the year of our Lord One thousand eight hundred and seventy-
five.
JOSEPH SUMMERSCALES. (L.S.)
