PROVISIONAL SPECIFICATION.
Improvements in Combing Machines.
I, BENJAMIN ALFRED DOBSON, of the Firm of Dobson and Barlow Limited,
of Kay Street Works, Bolton, in the County of Lancaster, Machine Makers, do
hereby declare the nature of this invention, which has been communicated to me
from abroad by Edward Williams Atkinson Merchant Engineer and Frederick
Bottomley, Head Mechanic, both of 152 Congress Street, Boston, in the State of
Massachusetts, in the United States of America, to be as follows :-
This invention relates to improvements in combing machines for cotton and other
fibrous materials and the object of the invention is to produce a more effectual
method of weighting the leather detaching rollers used in such machines.
In carrying out this invention the usual weights and weight hooks are dispensed
with and in their place we employ a bracket attached to the top of each of the lifter
levers this bracket acts as fulcra to levers which pass over and press upon the bushes
of the leather detaching rollers the other ends of said levers being held by springs
attached to a stationary part of the machine.
The action of this arrangement is such that when the lifter levers allow the
leather detaching roller to fall on and work with the fluted segment of the cylinder
the fulcra of the levers are lowered and the opposite ends of said levers (to which
the springs are attached) being raised thus exert the maximum amount of pressure
on the leather detaching roller the pressure being released as the lifter levers bring
the leather detaching roller to its normal position.

Improvements in Combing Machines.
I, BENJAMIN ALFRED DOBSON, of the Firm of Dobson and Barlow Limited,
of Kay Street Works, Bolton, in the County of Lancaster, Machine Makers, do
hereby declare the nature of this invention, which has been communicated to me
from abroad by Edward Williams Atkinson, Merchant Engineer, and Frederick
Bottomley, Head Mechanic, both of 152 Congress Street, Boston, in the State of
Massachusetts, in the United States of America, 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 improvements in combing machines for cotton and other
fibrous materials and the object of the invention is to produce a more effectual
method of weighting the leather covered detaching rollers used in such machines.
The usual weights and weight hooks are dispensed with and the object above
stated is effected as indicated on the two accompanying sheets of drawings in
which-
Figure 1 is a side elevation of the detaching rollers and lifter levers of a combing

page_text: machine to which the improvements are applied and Fig. 2 is a plan of the same
with certain parts omitted.
The comb cylinder is designated a, the nipper plate, the top comb c, the oscil-
lating lifter levers d, the movable leather covered detaching roller e, the other
detaching rollers f, g, the shaft or fulcrum of the lifter levers d is lettered h, the
trough and trumpet shaped guide i, and the calender rollers j.
All the foregoing parts may be of the ordinary construction and operate in the
ordinary manner well understood.
According to the present improvements a bracket is fixed on each lifter lever d
and each bracket & acts as a fulcrum for a lever m, a prepared surface m¹ on which
presses upon one of the bushes e' or journals of the leather covered detaching
roller e. At the other end each lever m is held by a coiled spring n attached at
the other end to some stationary part of the machine.
In action when the oscillating lifter levers d allow the leather covered detaching
rollers e to fall on and work with the fluted segments of the comb cylinder a the
fulcra of the levers m are lowered and the opposite ends of said levers (to
which the springs n are attached) being raised thus exert the maximum amount of
pressure on the leather covered detaching roller e, the pressure being relieved
as the lifter levers d return the leather covered detaching roller e to its normal
position.
Having now particularly described and ascertained the nature of this said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
The combination with the leather covered detaching roller e and the lifter levers d,
of the levers m at one end fulcrumed on the lifter levers, and at the other end drawn
down by springs upon the roller e, all substantially as and for the purposes herein
set forth.
