ACTUATING DABBING-BRUSHES FOR COMBING WOOL AND OTHER FIBROUS SUBSTANCES BY ELECTRICITY
Year: 1885

page_text: I, JOHN JAMES RICHARDSON, of Horsforth near Leeds, in the County of York
Steel Manufacturer do hereby declare the nature of my invention for "ACTUATING
DABBING-BRUSHES FOR COMBING WOOL AND OTHER FIBROUS SUBSTANCES BY
ELECTRICITY and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
My invention relates to driving the dabbing brushes of combing machines either
together or separately, and independently of the motion imparted to the other
machinery of the combing machine, by an electrical arrangement.
For this purpose I connect the crank or eccentric of the motor, driven by electric
power, by means of a connecting rod, to the vertical rods or frame attached to the
dabbing brush, or by other attachment of a similar nature thereby communicating
a vertical reciprocating motion to the dabbing brush.
I place the motor either over the dabbing brush, or at the side of it, working it
direct from the spindle of the motor, or I may fix it under the table of the combing
machine.
The electrical arrangement for giving the necessary power for driving the
dabbing brush, consists of stationery field, and rotary magnets, driven by dynamo
or voltaic electricity, in combination with suitable condensers, which are placed in
the circuit, to prevent sparking, and to neutralize the retarding effects of the
secondary currents. I also reserve to myself the right of substituting in any part
of the circuit, permanent for electro-magnets, either compound or otherwise.
In order to enable my invention to be fully understood I will proceed to describe
the same with reference to the accompanying drawings in which Figure 1 repre-
sents a front elevation of the dabbing apparatus of an ordinary Noble's or circular
comb, to which dabbing apparatus my electrical arrangement is applied, to give
motion thereto.
Figure 2 represents a side elevation of the same.
Similar letters refer to similar parts in both the figures.
The electro-motor, or other electric arrangement, for driving, is represented at A
and is supported by the cross stay M fixed between the two upright columns B.
Upon the top of each column is a bearing L which gives support to, and steadies
he shaft K. Upon each end of the shaft K is fixed a crank or eccentric J, which
.

page_text: communicates motion to the dabbing brush frame D by means of the connecting
rod G. The slide block F, to which the frame D of the dabbing brush is attached,
works between slides E and has a projecting pin upon which is placed one end of
the connecting rod G.
When it is desired to work the dabbing brush from the under side of the table,
the electro motor is placed under the combing table C, and the connecting rod
actuated by the crank or eccentric passes through a hole in the table, and is con-
nected by a projecting stud or pin to the slide block, to which the dabbing brush
frame is attached, and which slide block works in or upon vertical guides.
It is evident that dabbing apparatus actuated in the manner described can be
started to work before the other parts of the combing machinery commence
working and can be stopped instantly, at any time, independently of the other
parts of the machinery.
I make no claim to any particular form of electro motor, or other electrical
arrangement, for communicating motion, nor do I claim any particular form of
dabbing brush, but what I do claim is
1. The application of electricity to driving dabbing brushes of combing machines,
in the manner described or any mere modification of that method or arrangement.
2. The use of suitable condensers, placed in the circuit of electrical arrangements
for actuating dabbing brushes to prevent sparking and to neutralize the retarding
effects of secondary currents.
Dated this twenty eighth day of April 1885.
