IMPROVEMENTS IN THE CONSTRUCTION OF METALLIC FRAMES FOR WASHING AND WRINGING MACHINES, CHAFF AND TURNIP CUTTERS, AND OTHER SIMILAR FRAMES." PROVISIONAL SPECIFICATION
Year: 1880

page_text: LETTERS PATENT to Henry Herbert Andrew and William Lockwood, both of
Sheffield, in the County of York, for an Invention of "IMPROVEMENTS IN
THE CONSTRUCTION OF METALLIC FRAMES FOR WASHING AND WRINGING
MACHINES, CHAFF AND TURNIP CUTTERS, AND OTHER SIMILAR FRAMES."
PROVISIONAL SPECIFICATION left by the said Henry Herbert Andrew and
William Lockwood at the Office of the Commissioners of Patents on the
23rd December 1880.
HENRY HERBERT ANDREW and WILLIAM LOCKWOOD, both of Sheffield, in the
County of York. "IMPROVEMENTS IN THE CONSTRUCTION OF METALLIC FRAMES
FOR WASHING AND WRINGING MACHINES, CHAFF AND TURNIP CUTTERS, AND
OTHER SIMILAR FRAMES."
This Invention, which relates to improvements in the construction of metallic
frames for washing and wringing machines, and to other similar frames, has for
its object the production of such frames of greater strength and lightness, combined
with durability, than has been heretofore attained in their construction.
The frames for such machines, as above referred to, are now constructed of cast
iron, and by their formation in one piece or casting are unnecessarily heavy and
liable to fracture.
Now, according to our Invention, we construct the said frames of steel in the
form of bars or frames,
We roll the steel into bars of a T shaped, U shaped, H shaped, angular, or other
like shaped section, which are preferably formed in one length for each frame.
The bars thus formed are doubled and bent into a skeleton frame, parts of which
act as springs to put on the desired pressure on the roller, the parts of the side
which are between the upper and lower rollers being bent or curved in the shape
of a bow, and hardened and tempered, so that in their normal position they keep
the rollers closed together and resist their being forced apart by the action of
clothes being passed between them, thus dispensing with loose springs. The
skeleton frame is braced together with rods where necessary, and provided with
distance pieces between the two lengths or slides of each frame, so as to give the
required shape to the frame and to render the frame rigid. The said distance
pieces also serve the purpose of supporting the bearings of the machine where
necessary.
The extremities of the T or other shaped bars may form the feet or base of the
frames, and they may or may not be connected together.

HENRY HERBERT ANDREW and WILLIAM LOCKWOOD, both of Sheffield, in the
County of York. "IMPROVEMENTS IN THE CONSTRUCTION OF METALLIC FRAMES
FOR WASHING AND WRINGING MACHINES, CHAFF AND TURNIP CUTTERS, AND
OTHER SIMILAR FRAMES."
The said Invention, which relates to improvements in the construction of metallic
frames for washing and wringing machines, chaff and turnip cutters, and other
similar frames, has for its object the production of such frames of greater strength
and lightness, combined with durability, than has been heretofore attained in their
construction.
The frames for such machines, as above referred to, are now constructed of cast
iron, and by their formation in one piece or casting are unnecessarily heavy and
liable to fracture.
Now according to our said Invention we construct the said frames of steel in the
form of bars or frames, and formed of rolled steel, having a T, U, or H shaped,
angular, or other similar shaped section, which are preferably formed in one length
for each frame. The bars thus formed are doubled and bent into a skeleton frame,
parts of which act as springs to put on the desired pressure on the roller, the parts
of the side which are between the upper and lower rollers being bent or curved in
the shape of a bow, and hardened and tempered so that in their normal position
they keep the rollers closed together, and resist their being forced apart by the
action of clothes being passed between them, thus dispensing with loose springs.
The skeleton frame is braced together with rods where necessary, and provided
with distance pieces between the two lengths or sides of each frame, so as to give
the required shape to the frame and render the frame rigid. The said distance pieces
also serve the purpose of supporting the bearings of the machine where necessary.
The extremities of the T or other shaped bars may form the feet or base of the
frames, and they may or may not be connected together.
And in order that our said Invention may be fully understood we shall now
proceed more particularly to describe the same, and for that purpose shall refer to
the accompanying Drawing, which represents an end elevation of a mangling
machine provided with spring framing, arranged according to our said Invention.
A, A, represent respectively the two limbs of one end spring framing, formed of
a tempered rolled steel bar of T, U, or H shaped, or other similar suitable section,
presenting the required proportions for flexion, combined with tightness and rigidity.
The bar may be bent in one piece to the required configuration to receive the
journal or bearing blocks b, b', between the spring cheeks a, a', which may be
united or bent with a rectangular or curved head to receive an adjusting or pressure
screw C.
The terminations a', a', of the spring frame, which may be suitably secured by
bolts to a cast iron base D, are shewn of corresponding configuration and dimensions
to the parts a, a, for the purposes of symmetrical appearance and uniformity of
elasticity, but it is obvious that the spring framing may be formed into any desired
shape, and also that the ends may be continued to form the base frame D in one
piece instead of separate pieces of similar or different metal being employed.
These skeleton spring frames thus formed may be stayed by the bolts and
distance pieces c, c, d, d, in the required positions, so as to obtain the necessary
rigidity of structure and retain their symmetrical configuration; and such uniting

page_text: pieces may, if desired, be arranged to carry the roller or other similar bearings, as
represented at c¹.
Thus, when it is desired to apply pressure to the rollers of mangling or wringing
machines, or any other parts of machines of analogous requirements as to pressure
and automatic adjustment, these spring frames, supporting or carrying the bearings,
serve to uniformly transmit such force and rapidly compensate by their elasticity
for any sudden or irregular tax placed on such machines. For example, by the act
of turning the hand screw C₁ any required pressure may be transmitted to the
upper journal. block b, which is capable of vertical movement between the cheeks
so as to force the upper roller E in closer contact with the lower fixed one F. Now
should any varying resistance be caused to act on the rollers owing to irregular
impediments or obstructions formed by the clothes or other work passing through
them so as to necessitate some parallel play of the same, the elasticity of the spring
frames at once automatically supplies or allows this horizontal axial adjustment or
compensation according to the irregularities of work.
The cast iron frames of such machines, as heretofore constructed, inost necessarily
have other and more complex means of compensation; or the machines under certain
impending obstructions will either refuse to work, or fracture of the frames will
ensue.
Having now described and particularly ascertained the nature of our said
Invention, and the manner in which the same is or may be used or carried into
effect, we would observe in conclusion that what we consider to be novel and
original, and therefore claim as the Invention secured to us by the hereinbefore
in part recited Letters Patent is,―
The employment of spring frames for carrying the parts of the machines requiring
automatic adjustment or compensation according to irregularities of working, sub-
stantially as and for the purposes herein before described and as illustrated in the
accompanying Drawings.
In witness whereof, I, the said William Lockwood, for myself and on behalf
of Henry Herbert Andrew, have hereunto set my hand and seal, this
18th day of June, in the year of our Lord 1881.
