Improvements in Dabbing Brush Motions for Combing Machines.
I, PATRICK KELLY, of Sutton Mill, Cross Hills, in the County of York,
Combing Overlooker, do hereby declare the nature of this invention to be as
follows:-
This invention relates to the making of a packing peice and combining same
with the dabbing motions of combing machines, and has for its object the con-
struction of the packing piece so that the eccentric does not wear flat in places, and
wear hollow places in the horns of the slide plate between which the eccentric
rotates, but to keep the eccentric circular and the horns straight and to make
such arrangements in the packing peice, that when any wearing takes place,
the respective parts may be regulated so that they will work without much slack
or knocking.
To carry out the above object, I form an eccentric on the dabbing motion
driving spindle and form horns or extensions on the dabbing motion slide plate,
and place around the eccentric between the horns or extensions of the slide plate,
a packing piece constructed so that the wearing of the eccentric may be taken up
by closing the clips around the eccentric, and the wearing of the ends of the pack-
ing piece and of the horns or extensions of the slide plate is taken up by set
screws or bolts and nuts and packings and kept at a working fit without much
slack or knocking, such as is well known and experienced with the dabbing motions
as now made.
COMPLETE SPECIFICATION.
Improvements in Dabbing Brush Motions for Combing Machines.
I, PATRICK KELLY, of Sutton Mill, Cross Hills, in the County of York,
Combing Machine Overlooker, 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 the construction of a packing piece and combining
same with the slide plate of the dabbing motion of combing machines, and has for its
object, the arrangement of the said packing piece so that, flat or hollow places are not
worn on the eccentric or crank, or on the horns or flanges of the slide plate between
which the crank or eccentric rotates; and to so construct the said packing piece
that, any wearing of the respective parts may be adjusted in a manner that, the
dabbing motion can be worked without much slack or knocking developing between
the crank or eccentric and horns or flanges of the sliding plate.

page_text: In describing my invention in detail, reference is made to the accompanying
sheet of drawings in which Fig. 1 represents an elevation partly in section of a
dabbing motion to which my improvement is applied.
Fig. 2 is a front view drawn to a larger scale of my improved packing piece in
position.
Fig. 3 is a view of a crank suitable for operating the dabbing brush slide, and
Fig. 4 is an end view of the crank. Both these figures are drawn to the same
scale as Fig. 1.
In carrying out my object, I form a crank or the like A, on the dabbing motion
driving spindle B, mounted and operated in the ordinary manner, and on the slide
plate C, form horns or flanges D, D, between which the crank rotates, and around
the crank pin A, or eccentric as the case may be, is placed my adjustable packing
piece. E, forms one portion of the bush or journal placed around the crank
pin, A, and is provided with a shoe E¹. The other portion of the bush or journal
around the said crank pin is indicated by F, and outside this bush F, is a strap G,
provided with a shoe G¹, these shoes E, and G¹, fit and slide between the horns or
flanges D, D, and the respective parts are secured together by the bolts and
nuts S, S.
The hole through the parts E, and F, forming the bush or journal is bored to
fit the crank pin A, and when the surface around the crank pin is worn too slack
for noiseless running, on releasing the nuts S, S, the joints or faces H, between the
flanges J, and K, of the said bushes, may be reduced in a manner so as to
"take
up the slack" by causing the parts E, and F, forming the bush or journal to be
in closer contact with the crank pin; and in order to keep the shoes E, and G¹, a
working sliding fit between the horns or flanges D, D, the joints or faces between
the flanges K, and L, may be packed apart by material of a suitable thickness
and secured on tightening the nuts S, S, thus bringing the faces of the said shoes
into proper working contact with the horns or flanges D, D. By these arrange-
ments, the working surfaces between the crank pin A, and bush around same,
and between the shoes E¹, and G, and horns or flanges D, D, may be kept easy
working fits, thus obviating the amount of "slack" that is developed when the
slide plate C, is operated by the crank or eccentric working in direct contact with
the horns or flanges D, D, in the manner as hitherto.
Having now particularly described and ascertained the nature of this invention,
and in what manner the same is to be performed, I declare that what I claim is :-
An adiustable packing piece placed between the horns or flanges D, D, of slide
plate C, operated by a crank or eccentric, all arranged substantially in the manner
as shown and described and for the purpose as hereinbefore set forth.
Dated this 26th day of January 1899.
