Year: 1881

page_text: LETTERS PATENT to John Baldwin, William Baldwin, Robert Haddon, and
James Crossley Dyson, all of Halifax, in the County of York, for an
Invention of "IMPROVEMENTS IN MACHINERY FOR COMBING WOOL AND
OTHER FIBROUS SUBSTANCES."
PROVISIONAL SPECIFICATION left by the said John Baldwin, William
Baldwin, Robert Haddon, and James Crossley Dyson at the Office of the
Commissioners of Patents on the 22nd June 1881.
JOHN BALDWIN, WILLIAM BALDWIN, ROBERT HADDON, and JAMES CROSSLEY
DYSON, all of Halifax, in the County of York. IMPROVEMENTS IN MACHINERY
"
FOR COMBING WOOL AND OTHER FIBROUS SUBSTANCES."
This Invention relates to a new method of operating the dabbing brushes, and
the improvements consist in fixing the disc carrying the crank or eccentric lower
down the pillar than hitherto. Motion is communicated to the disc by means of
a friction disc or wheel on the end of the ordinary friction between the peripheries
of the two discs they may be grooved.
By this arrangement the rod attached to the brushes is shortened and its weight
diminished, whilst the crank or eccentric being situated midway of the pillar the
vibration caused thereby is greatly reduced.

Crossley Dyson in the Great Seal Patent Office on the 22nd December

JOHN BALDWIN, WILLIAM BALDwin, Robert Haddon, and JAMES CROSSLEY
DYSON, all of Halifax, in the County of York. "IMPROVEMENTS IN MACHINERY
FOR COMBING WOOL AND OTHER FIBROUS SUBSTANCES."
This Invention relates to a new method of operating the dabbing brushes, and
the improvements consist in fixing the disc carrying the crank or eccentric lower
down the pillar than hitherto has been the custom. Motion is communicated to
the disc by means of a friction disc or wheel on the end of the ordinary cross shaft.
To secure the requisite amount of friction between the peripheries of the two discs
they may be grooved.
By this arrangement the rod attached to the brushes is shortened and its weight
diminished, whilst the crank or eccentric being situated midway of the pillar the
vibration caused thereby is greatly.reduced..
In order that our Invention may be more fully understood we herein give
reference to the accompanying Sheet of Drawings, in which Fig. 1 represents side
elevation of our improved apparatus; and Fig. 2, a front view thereof; Figs. 3
and 4 are details shewn full size.
In Fig. 1 we have shewn the large circle A and small circle B at their tangent
or point of nearest contact where the fibres come under the operation of the
dabbing brush C. The stem of the brush is supported in slide bearings D, which
are formed on the face of the bracket E, the bracket being fixed to the pillar F.
In the interior of the pillar is the usual upright shaft G carrying the bevil
wheel H, which gears with the wheel J on the driving shaft K, upon the end of
which is mounted a friction wheel or disc L, the periphery of which is in contact
with that of a similar disc M mounted upon a short shaft N, which runs in
journals on the top of the bracket E. The shaft N carries a face plato P, in which
is a crank pin a connected by rod S to a stud c fixed in the stem of the brush C.
Around the stud c is a collar T having a screw d, which passes through a plate e
cast on the stem of the brush. When it is desired to vary the dabbing motion of
the brush the nut at the back of the stud c is slackenod and the nuts f adjusted
so as to place the brush nearer to or further from the stud c, as may be required.
This arrangement, whilst permitting great accuracy of adjustment, also increases
the rigidity of the stud c. By means of a similar nut and screw g the bracket E
may be raised or lowered upon upon the pillar.
In order to securo contact between the two friction discs, the bearings of the
disc M rost upon springs W contained in the journal boxes, as shewn in detail in
Figs. 3 and 4.
Having thus described the nature of our Invention and the manner in which the
same may be performed, wo would have it understood that we claim,-
The employment of the friction wheels or discs L and M for operating the
brush C, in manner substantially as herein shewn and described.
In witness whereof, I, the said Robert Haddon, for and on behalf of myself
and the said John Baldwin, William Baldwin, and James Crossley Dyson,
have hereunto set my hand and scal, this Nineteenth day of December,
in the year of our Lord One thousand eight hundred and eighty one.
