AN IMPROVED CONSTRUCTION OF FRAME FOR WASHING MACHINES, WRINGING
MACHINES, AND SEWING MACHINES."
This Invention relates to an improved construction of frame for mounting and
carrying the rollers and working parts of washing, wringing, and such like or
similar machinery, or for supporting the body of machinery, such as sewing
machines, the object being by the construction of parts to provide for the necessary
supporting parts, bearings, journals, and gearing, or the tables for supporting the
machines, and the application of the springs to the rollers of washing, wringing,
cylinder, knife cleaning machines, and fluting or crimping machines, and so forth,
at the same time that the torsional strain and probable twisting of light wrought
metal framing will be prevented by the bracing and clamping blocks, which
together with bent tubular portions constitute the improved framing, whereby also
there is secured very considerable lightness of the parts, great strength and facility
for dismounting the machines and packing the parts thereof for transport. The main
supports of the frame consist of tubes or strips of grooved wrought metal bent at
the upper or lower portion to the configuration of the framing to be produced, and
with blocks hollowed out to embrace the main support and bored through to
receive screw bolts. With these blocks there is made in the centre portion of the
machine bracing frames or piece, which give support across the frame between the
standards, and the bracing blocks themselves along with the securing bolts bind
the main supports together transversley, and similar bracing blocks are bolted on.
to the machine framing, and carrying the bearings for the roller shafts and gearing.

page_text: For wringing, mangling, cylinder knife cleaning, fluting or crimping machines,
there is provided for applying the pressure to the cylinders, along the main
supports of the framing and lying therein and guided by the brace blocks, or
passing through the same if said supports are tubular, specially bent, or arched
rods which at the arched portion pass over grooved heads of the pressure blocks, 5
which rest upon the axle of the top roller; and the lower ends of the said rods are
screwed to receive nuts to bolt on a cross bar upon which the pressure spring
operated by set screw will bear, so as to apply the pressure equally upon both ends
of the axle simultaneously.
In the case of forming the upright portion of the frame of a single tube split 1
and bifurcated at the ends and braced together, as desired.
A portion of the tube will be cut through and removed, and the journals bo
introduced into the section, and then covered so as to enclose the parts, thus
protecting them from dust, and preventing the spread of oil or other lubricant.

ALBERT SHAW, of Lockwood, Near Huddersfield, in the County of York.
AN IMPROVED CONSTRUCTION OF FRAME FOR WASHING MACHINES, WRINGING
MACHINES, AND SEWING MACHINES."
This Invention relates to an improved construction of frame for supporting the
rollers and working parts of washing, wringing, and sewing machinery.
The main supports of the frame consist of tubes of wrought metal bent to the
configuration of the framing required. These supports may be braced together
by cross bars which may be either solid or hollow, the cross bars being connected
to the uprights by plates and bolts. For wringing machines in which rollers
are employed, the hollow framework may serve as a cover for the rods, which are
employed to put pressure upon the said rollers.
In order that this Invention may be more clearly understood, I herein give
reference to the accompanying Sheet of Drawings illustrative thereof. Fig. 1 is
a front elevation, and Fig. 2 an end view of a wringing machine, the rollers A
and B of which are supported by framework C composed of tubes of wrought
iron connected and strengthened by means of a cross rail D and plates E, to which
the cross rail is secured by bolts F. The plates E also support the blocks G
through which the axis of the rollers pass, the upper block being rounded and
grooved to contain the curved portion of the pressure rods H, the rods at each
end of the machine being formed from a continuous piece, the two ends being
inserted into the upper ends of the main supports and passing out at holes a. The
ends of the rods are thus secured to the plate J, and pressure applied by spring K
and screw L in the usual manner.
From the example herein given it will be readily understood that similar frames
may be employed for sewing and other machines, and it will be found that frames
so constructed are stronger than cast metal frames of equal weight, whilst they are
more portable and less liable to breakage.
Having thus described and ascertained the nature and object of this my
Invention, and shewn by Drawings in what manner the same is or may be
performed or carried into practical operation, I would have it understood that
I claim,
The employment of metal tubing in the construction of washing and wringing
machine frames, in the manner substantially as herein shewn and described.
In witness whereof, I, the said Albert Shaw, have hereunto set my hand and
seal, this Eighth day of March, in the year of our Lord One thousand eight
hundred and eighty two.
