PROVISIONAL SPECIFICATION.
Improved Mode of and Apparatus for Applying Direct Uniform
Pressure to Rollers or other parts of Machinery.
I, SAMUEL EDWARD ASQUITH, of 7, Grange Terrace, Allerton, Bradford, in
the County of York, Machinist, do hereby declare the nature of this invention to
be as follows:-
This invention relates to a new method of and apparatus or mechanism for
applying direct pressure on to rollers, shafts, or other parts of machinery.
According to my invention I construct a hollow metal bar having one end of
the hollow or cavity slightly enlarged and containing a spiral spring therein, one
end of such spring resting against a shoulder formed by the end of the enlarged
part of the hollow. The metal comprising the enlarged part of the hollow bar has
a continuation, cast or formed in a piece therewith, and of a square or other shape
(to suit different circumstances) excepting on one side which is provided with a
slanting, angular, inclined, or curved surface. A rod having a screw-threaded end,
is passed right through this continuation and also through the centre of the spiral
spring, in the enlarged part, and the rest of the hollow bar, so that the screw-
threaded end of the rod shall extend beyond the end of the said hollow bar. The
other end of the rod has a square head formed thereon taking into a hollow or
cavity in the continuation of the enlarged part. A similar part having a like
slanting, angular, inclined, or curved surface thereon, corresponding to the con-
tinuation on the enlarged part is attached to the other end of the hollow bar, or
may, in some cases, be cast thereon or in a piece therewith. The parts having the
slauting, angular, inclined, or curved surface thereon are adjusted in position
against similarly shaped surfaces arranged in the uprights, supports, or other
bearings carrying the rollers, shafts, or other mechanisms. A screw-threaded nut,
screw-threaded wheel, or similar device takes on to the screw-threaded end of the
rod, for the purpose of adjusting the length of up and down motion of the bar
against the bearing-block or brass of the roller or other part.
By tightening up the screw-threaded nut, screw-threaded wheel, or the like the
slanting, angular, inclined, or curved surfaces are caused to slide against each other
in a wedging fashion and so put pressure on to the roller, shaft, or other part.
The above constitutes one example of the method of carrying my invention into
practice, but it must be understood that the parts are capable of various alterations
to suit different circumstances.

COMPLETE SPECIFICATION.
Improved Mode of and Apparatus for Applying Direct Uniform
Pressure to Rollers or other parts of Machinery..
I, SAMUEL EDWARD ASQUITH, of 7, Grange Terrace, Allerton, Bradford, in
the County of York, Machinist, do hereby declare the nature of this invention
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:—
This invention relates to a new method of and apparatus or mechanism for
applying direct pressure on to rollers, shafts, or other parts of machinery.

page_text: According to my invention I construct a hollow metal bar having one end of the
hollow or cavity slightly enlarged and containing a spiral spring therein; one end
of such spring resting against a shoulder formed by the end of the enlarged part of
the hollow. The metal comprising the enlarged part of the hollow bar has a
continuation, cast or formed in a piece therewith, and of a square or other shape
(to suit different circumstances) excepting on one side which is provided with a
slanting, angular, inclined, or curved surface. A rod, having a screw-threaded
end, is passed right through this continuation and also through the centre of the
spiral spring, in the enlarged part, and the rest of the hollow bar, so that the
screw-threaded end of the rod shall extend beyond the end of the said hollow bar.
The other end of the rod has a square head formed thereon taking into a hollow or
cavity in the continuation of the enlarged part. A similar part having a like
slanting, angular, inclined, or curved surface thereon, corresponding to the con-
tinuation on the enlarged part is attached to the other end of the hollow bar, or
may, in some cases, be cast thereon or in a piece therewith. The parts having the
slanting, angular, inclined, or curved surface thereon are adjusted in position
against similarly shaped surfaces arranged in the uprights, supports, or other
bearings carrying the rollers, shafts, or other mechanisms. A screw-threaded nut,
screw-threaded wheel, or similar device takes on to the screw-threaded end of the
rod, for the purpose of adjusting the length of up and down motion of the bar
against the bearing block or brass of the roller or other part.
By tightening up the screw-threaded nut, screw-threaded wheel, or the like the
slanting, angular, inclined, or curved surfaces are caused to slide against each
other in a wedging fashion and so put pressure on to the roller, shaft, or other
part.
The above constitutes one example of the method of carrying my invention into.
practice, but it must be understood that the parts are capable of various alterations
to suit different circumstances.
Referring to the drawings accompanying this Specification,
Fig. 1 represents in front elevation and Fig. 2 in sectional elevation, one form
of the apparatus constructed according to my invention.
Fig. 3 is a section of same through the line a, b, Fig. 1; and
Fig. 4 is a right hand end view.
Figs. 5 and 6 show, in part front elevation, and left end elevation (partly in
section) respectively, another form of the apparatus adapted to the top roller of a
domestic wringing machine.
Fig. 7 is a plan of the underside of the cross-head and parts therein contained
shown in Fig. 5.
Fig. 8 shows one method of applying the invention to vertical rollers, and is a
part front elevation, partly in section, on a reduced scale.
Fig. 9 is a diagram illustrating a method for putting on pressure with a weight
instead of a spring.
A is the hollow metal bar; A', A², the right and left slanting, angular, inclined,
or curved continuations respectively, hereinafter termed the right and left slants.
B is the rod through the hollow cavity or core of the bar A, and C the spiral
spring coiled thereon; b is the square head on rod B, and 6', in Figs. 5 and 7, the
screw-threaded wheel for adjusting the length of the rod B and so putting on more
or less pressure to the roller. This wheel b¹ is replaced by a screw-threaded nut b×
in Fig. 8.
In Figs. 1 and 2, D is a screw-threaded bush which takes on to the threaded
ends of the parts A, A' and A³, and allows of the bar being lengthened to suit
circumstances.
The invention is specially adaptable to domestic washing and wringing machines
and is thus shown in Figs. 5, 6 and 7. In the form of apparatus here represented,
mounted in the crosshead E, the cavity or core in the bar A extends only a short
distance therein, instead of right through as in Figs. 1 to 4. The right and left
slants A and A here bear against the bearing blocks F, F, respectively, and inay

page_text: be made to work more sweetly by means of top runners e, e¹, mounted in the
crosshead E, and under runners mounted in the bearing blocks F, F. One of these
under runners is represented at f, Fig. 6.
The invention is also specially applicable to fibre combing machine drawing off
rollers, for applying pressure to the pressure roller, the bar A and slants being
mounted vertically for this purpose. In Fig. 8 I have shown, as an example, one
method of arranging my invention for vertical rollers. In this case I prefer to
employ flanged wedges, such as those represented at G, G', working against the
bearing blocks; the flanges of such wedges guiding them in their motion sideways
and serving as a means for retaining them in the cross-beams or supports H, H¹.
The runners e, e¹, are here mounted in loose bearing blocks and are capable of
adjustment by means of the set screws or hand wheels J and J'.
Fig. 9 indicates an example of an arrangement for putting on pressure with a
weight by the employment of a slanting vertical block L working against a runner a,
the lower part of such block L having the weight M attached thereto. A similar
arrangement may be employed for vertical rollers.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:
1. The construction and arrangement of the improved apparatus for applying
direct uniform pressure to rollers or other parts of machinery substantially as
described and shown on the drawings with reference to Figs. 1 to 4 inclusive or any
mere modification of same.
2. The construction and arrangement of the improved apparatus for applying
direct uniform pressure to rollers or other parts of machinery substantially as
described and shown with reference to Figs. 5 to 7 inclusive or any mere modification
of same.
3. The construction and arrangement of the improved apparatus for applying
direct uniform pressure to rollers or other parts of machinery substantially as
described and shown with reference to Fig. 8 or any mere modification of same.
4. The application and use of my improved apparatus for applying direct
uniform pressure for the rollers of domestic wringing and like machines substan-
tially as described and shown in Figs. 5 to 7 inclusive.
5. The employment of my improved apparatus for applying pressure to the
pressing roller of the drawing off rollers of machinery for combing fibres.
