COMPLETE SPECIFICATION.
Improvements in Wool-combing Machines.
I, JOHN SOOTHILL, of Johnston, in the County of Providence, State of Rhode
sland, United States of America, Wool-comb Operator, do hereby declare the
ature of my invention and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement, reference
being had to the accompanying drawings forming part of this Specification :-
11
This invention has reference to improvements in that part of a wool-combing
machine known as the dabber driving-pulley.
The object of this invention is to produce a new and improved form of dabber
driving-pulley which will continue in its operation for a short time after the comb
has ceased to revolve. To attain this end I have invented certain novel features
of construction and combination of parts, as will be more fully described herein-
after and pointed out in the claims.
Figure 1 is a view of a counter-shaft support of a wool-combing machine and the
dabber-driving mechanism secured thereto.
Figure 2 is a vertical sectional view of the improved dabber driving-pulley.
Figure 3 is a view of the inner construction of the improved pulley.
In the ordinary construction of a wool-combing machine, the dabber driving-
pulley is rigidly secured to the counter-shaft and stops and starts with the
mechanism driving the comb and other portions of the wool-combing machine, in
consequence of this construction the wool, lying between the comb and the dabber-
brush, remains in that position until the machine is started; as the comb begins
to revolve at the first motion of the driving mechanism, the wool, which has
remained between the comb and dabber-brush, is apt to be carried past the brush
before the brush is driven against the wool sufficiently to force that portion of the
wool into the comb, thus causing what is called a fault. My invention is for the
purpose of overcoming such faults and 1 will now proceed to describe it more
particularly.
Similar numbers of reference designate corresponding parts throughout.
In the drawings 4 indicates the countershaft-support of a wool-combing machine
and 5 is the countershaft, 6 being a tight pulley secured to said shaft and 6¹ a
loose pulley revolving thereon and driven by the belt 7. At the outer end of the
countershaft 5 is secured the balance-pulley 8 which is revolvable thereon and has
an inwardly-extending circumferential flange 9, the inner edge of this flange 9
moves around in easy contact with the back-plate 10 which is secured on the
countershaft 5 by a set-screw 11 and is provided with the spindles 12-12 to which
are pivotally secured the spring-operated pawls 13; these pawls may be operated,
as shown in the drawings, by coiled springs 14 carried on rods bearing against the
ears 15, or they may be operated by other suitable springs, the object being to
force the end of the pawl into contact with the teeth of a ratchet-wheel 16 carried
on the sleeve 8¹ of the balance-pulley 8 and secured thereto by a key.
The teeth, cut on the ratchet-wheel 16, are cut in a direction so that, by contact
with the pawls 13, they keep the balance-pulley 8 on the flange 9, on which the
dabber driving-belt 17 is carried, from turning backward.
The dabber-brush is carried on the rod 18 which is moved up and down by a
block sliding in guides in the frame 19 and operated by the crank-eccentric 20 and
pulleys 21 to which motion is imparted through the belt 17.
shipped
The operation of my improved pulley is as follows;-When the belt 7
from the tight-pulley 6 to the loose-pulley 6', the belt, driving the comb, will also
be shipped and the comb stopped, the weight and momentum, acquired by the
balance-pulley 8, will, however, continue to revolve that pulley independently of

the countershaft and to drive the dabber-mechanism through means of the belt 17;
the dabber-brush will thus be driven down against the comb several times and
sufficiently to force the wool, lying under the dabber-brush, into the comb, when,
now, the machinery is started, the pawls 13 will engage with the ratchet-wheel 16
and drive 'that wheel and the balance-pulley 8 carrying the belt 17, the dabber-
brush will begin to operate before a new supply of wool is presented to its force
and, therefore,,no wool can pass away from under the brush without being
thoroughly combed.

Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:
Claim 1. In a wool-combing machine, a balanced-dabber driving-pulley inde-
pendently revolving on the counter-shaft and provided with a ratchet-wheel, and
mechanism carried on said countershaft and adapted to engage said ratchet-wheel
to drive said pulley, as described.
2. In a wool-combing machine, the combination with the dabber-mechanism
and a belt adapted to drive such mechanism, of a balanced pulley independently
-rotatable on the countershaft and carrying the dabber driving-belt, and mechanism
carried on said countershaft and adapted to drive said pulley, as described.
3. In a wool-combing machine, the combination with the countershaft 5 having
the balanced loose-pulley 8 carrying the dabber driving-belt and provided with
the ratchet-wheel 16 keyed to the pulley-sleeve 8', of a back-plate 10 having the
spindles 12-12 and the spring-operated pawls 13-13 pivotally secured thereto,
as and for the purpose. described..
