Improvements in Apparatus for Actuating Dabbing Brushes 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 and in what manner the
same is to be performed, to be particularly described and ascertained in and by the
following statement:-
This Invention has for its object, the construction and arrangement of an apparatus
for giving the necessary reciprocating motion to what are known as dabbing brushes
on combing machines; and in such a manner that, the position of the same in relation
to its distance from the driving shaft and comb circles, can be regulated to suit the
length of the driving belt also to so construct the necks or journals, that oil is stored
therein for lubricating whilst in motion; and consists in making the usual supporting
bracket in two parts, one part being rigidly secured to the machine, and the other part
bolted thereto also by forming in the connecting rod and other journals, one or
more wells or recesses, the well in the former I fill with felt for retaining the
lubricant.
In describing my invention more in detail, reference is made to the accompanying
drawings, in which Fig. 1. represents a side view partly in section of an apparatus
constructed according to my invention. Fig. 2. a front view with the driving pulley
removed, and also a portion of the front cover plate; and Fig. 3 a view of the con-
necting rod partly in section.
The apparatus is fixed to each machine pillar A. in the usual position, but instead of
making the principal parts of the bracket in one casting, I form the same in two; by
constructing a saddle B. with the usual lugs for securing the same to the respective
pillars. To each saddle B, I secure a box bracket C, by bolting the same thereto with
bolts D. passing through slot holes in one or both plates, extending in vertical
direction, to admit of the said box bracket being adjusted in a vertical direction.
At each side of the box bracket C, I form a journal E, in which I mount a double
webbed crank shaft F, on one end of which I secure a driving pulley G, the same
being driven by a belt from a pulley mounted in the usual position.
I cut in the crank pin F', a groove, and place on the former a connecting rod H,
the opposite end of which is secured but free to work on the connecting stud J, fixed
[Price 6d]

page_text: to the brush slide plate K; by which connection, on the crank rotating, a recipro-
cating motion is given to the brush slide plate, and dabbing brush K¹, attached
thereto.
The bottom end of the connecting rod I extend at H, and form therein a well,
which I fill with felt L, into which the oil runs and is absorbed by the felt in the
other necks or journals E, a groove is cut on each side, with channels extending there-
from to the well or recess in centre of neck.
The apparatus is driven by a belt on pulley G in the ordinary manner, and in order
to adjust the driving belt when it stretches without having to remove the same and
cut it shorter, and thus making it too tight as is often the case; I adjust the apparatus
so as to give to the belt the exact frictional contact, for operating the dabbing brush K³,
at the requisite speed, in the following manner.
The bolts D are unscrewed to admit of the lowering of the box bracket C. the
necessary distance for giving to the belt the proper stretch or tightness; the dabbing
brush K¹ being adjusted to compensate for the lowering of the bracket by unscrewing
the nut N, and raising the slide K a proportionate distance; the several nuts being
afterwards tightened, by which means, I am enabled to use an endless belt having a
spliced joint and to keep the same the necessary tightness without cutting when it
becomes too slack.
On the apparatus being put in motion, I find the crank pin is kept sufficiently
lubricated for a considerable time; by the oil stored in the felt packing L in the well
of connecting rod being raised from the said well into contact with the crank pin
by the quick rotation of the crank, thus lubricating the crank pin neck sufficiently by
keeping it moist, when running at a high speed; the oil in the wells and channels of
the necks or journals E. is retained therein by the annular grooves cut near each end
of the neck.
The space in which the dabbing brush slide plate K reciprocates, is recessed on each
side at M, and filled with felt for retaining oil, by which the slide is lubricated, the
slide plate K being covered by a plate P.
By constructing the apparatus as described with stores for lubricant, it can be run
at a very high speed; and the principal working parts kept lubricated by drawing
from the felt packed in each well or recess; thereby requiring less attention on the
part of the attendant; and with less liability of the oil being thrown off by the quick
movement of the parts on to the fibre in the comb circles.
Having now particularly described and ascertained the nature of my inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is
1. The formation in two parts B. and C. of a dabbing motion bracket, for the purpose
of adjusting the frictional contact of the driving belt with the pullies substantially in
the manner described.
2. The employment of felt packed in the end of a dabbing motion connecting rod,
substantially in the manner and for the purpose described.
3. A neck in the centre of which is a well having channels cut communicating with
grooves on each side of the same for the purpose described.
4. The combination of a dabbing brush reciprocating slide plate K. with recesses M,
filled with felt substantially in the manner and for the purpose described.
