IMPROVEMENTS IN APPARATUS FOR ACTUATING DABBING BRUSHES FOR COMBING MACHINES
Year: 1884

page_text: We, OLIVER BROOK LISTER of Shetcliffe Mill, Dudley Hill near Bradford, in
the County of York, Spinner, and HENRY BATTY of the same place, Mechanic,
do hereby declare the nature of our invention for IMPROVEMENTS IN APPARATUS
FOR ACTUATING DABBING BRUSHES FOR COMBING MACHINES, and in what manner
the same is to be performed, to be particularly described and ascertained in and
by the following statement:-
The object of our invention is to arrange an apparatus for giving the necessary
reciprocating motion to the dabbing brushes of combing machines in such a manner,
that the principal working parts are adjustable and self lubricating; and consists
of securing to each pillar in the centre of the small circular combs a box bracket, in
which is mounted a revolving shaft having conical journals or bearings, which
revolve in adjustable bushes; and to the said shaft is secured an eccentric, the
periphery of which is conical and revolves between projections forming part of a
vertical sliding plate, to which is attached another sliding plate with the dabbing
brush s 'cured to the foot thereof. By the regulation of the adjustable bushes, any
"slack" that may develop in the journals or eccentric can be taken up, and by the
bottom portion of the first named slide dipping into oil at each strike, the oil is
agitated, and all the principal parts efficiently lubricated.
In order that our invention may be better understood, we will describe the
same more in detail by referring to the accompanying drawings, in which Fig. 1
represents a side elevation of our apparatus shewn in section; Fig. 2 is a front
view, the driving pulley being removed in order to more clearly illustrate the same;
Fig. 3 is a plan, Fig. 4 is an end view of one of the adjustable bushes in which the
shaft rotates, and Fig. 5 a side elevation drawn to a reduced scale, shewing the
manner in which our apparatus is driven.
Our improved apparatus is fitted in the same manner to each centre pillar of the
small circular combs, but in the following description we have only described the
apparatus in connection with one side of the machine.
The box bracket A is secured to the ordinary centre pillar B, and motion is
transmitted from the pulley C, on the top or main driving shaft D, by means of
baud E to the pulley F of the apparatus, which is secured on the shaft G. The

page_text: journals or bearings G and G³ of this shaft are made conical, tapering in opposite
directions, and are mounted in adjustable bushes J regulated by screws K. On the
said shaft is also secured eccentric L, the periphery being conical, tapering in the
same direction as journal G¹, and fitting between the projections M and M of
sliding plate M², which reciprocates in a vertical direction, guided by the angular
slides N as shewn by plan Fig. 3; this sliding plate is attached by bolt O to the
front sliding plate P, to the foot of which is secured the dabbing brush R, which
reciprocates and dabs or presses the fibre between the teeth of the circular combs.
By the regulation of the bushes J, the eccentric L can be adjusted to work
between the projections M and M², and the shaft bearings and G³ to revolve
freely in the said bushes; and by the projection S at the bottom of sliding plate M²
dipping into the oil T at the bottom of box bracket, it is agitated, causing it to fly
about and lubricate the whole of the principal working parts; the oil flowing
through the upper channels cut in the bushes J into the recesses U, and back
through the lower channels into the interior of the box.
Having now particularly described and ascertained the nature of our said.
invention, and in what manner the same is to be performed, we declare that what
we claim, is:
Actuating dabbing brushes of Combing machines by a self lubricating apparatus,
the eccentric L having a conical periphery, and the shaft conical necks G¹ and G
running in adjustable bushes J, all arranged substantially in the manner described,
and as illustrated by the accompanying drawings.
Shafts prepared with conical necks running in adjustable bushes arranged
substantially in the manner and for the purpose hereinbefore described, and as
illustrated by the accompanying drawings.
Dated this 2nd day of December 1884.
