PROVISIONAL SPECIFICATION.
Improvements in the Method of and Apparatus for Straightening
Undressed Hard Drawn Steel Wire for Cards and for other
suitable purposes.
I, JOHN EDWARD WALSH of The Newlands, Warley near Halifax in the
County of York, Mechanical Engineer, do hereby declare the nature of this inven-
tion to be as follows:-
:-
I employ upon a suitable frame or gantry a shaft preferably horizontal and in
fixed bearings, to this shaft is imparted a rotating and at the same time a recipro-
cating or backwards and forwards end wise notion, at preferably each end of this
shaft are hardened steel bosses working against which are a number of hardened
steel narrow pressure necks, pressure being preferably put upon each neck by
springs upon suitable levers, between each neck and its steel boss is passed the
wire to be straightened, each wire having separate springs or weights for putting
the required pressure upon it when being passed through, various sizes may be
straightened at the same time.
The springs are arranged so that the pressure can be regulated to suit the
different sizes of wire, for threading the wire between the boss and the pressure
necks, excentric ended levers may be used which draw the necks out of contact
with the bosses, and when the lever is turned back, the corresponding neck is again
in contact with its wire, by this means any wire can be thread between the boss
and its neck without stopping the machine, the main or driving shaft is operated
from any source and has a cam with a groove having three or more ways or turns,
operating the adjustable lever which gives the backwards and forwards motion to
the shaft.
Upon the shaft is a chain wheel with gear wheel loose upon the shaft, a gear
wheel gearing with a double gear wheel upon a stud, drives the chain wheel so that
the speeding of the driving shaft and the straightening shaft may be independent,
wincels and blocks for holding and receiving the wire are arranged upon suitable
frame or frames by. having longer bosses and increasing the number of necks, any
number of wires can be passed through the machine, and a number of sized
machines may be mounted on one gantry, the oil upon the wire can be taken off
it by passing it through emery indiarubber or by other means on its passage to the
block or winder, if necessary the wire may pass one or more times around a tension
pulley placed between the winder and the steel boss or straightener.

COMPLETE SPECIFICATION.
Improvements in the Method of and Apparatus for Straightening
Undressed Hard Drawn Steel Wire for Cards and for other
suitable purposes.
I, JOHN EDWARD WALSH of The Newlands, Warley near Halifax in the
County of York, Mechanical Engineer, do hereby declare the nature of this
invention, and in what manner the same is to he performed, to be particularly
described and ascertained in and by the following statement :-

page_text: Fig. 3. is an elevation of hardened pressure necks or concaves, and hardened steel
boss, between which the wire passes.
Fig. 4. is a detail view showing method of adjusting the pivotted lever.
I employ upon a suitable frame or gantry A, a shaft B preferably horizontal
and in fixed bearings C, preferably at each end of this shaft are hardened steel
bosses D, working against which (in suitable box or boxes E fixed upon the
frame A) are a number of narrow hardened steel pressure necks F; pressure being
preferably put upon each neck by means of levers G, and springs H, the said
springs being also arranged so that the pressure can be regulated or adjusted (to
suit the different sizes of wire being operated upon) by means of a thunibscrew J,
or in any other suitable manner.
Between each neck and its steel boss is passed the wire K, (to be straightened),
this being accomplished by withdrawing the necks by means of an eccentric ended
hand lever L, which pushes back the lever G, and with the spring M and stud M'
draws its pressure neck out of contact with the boss D, so allowing the wire to be
passed between the same; on turning back the hand lever, the spring H returns
the neck to its position.
By this arrangement of levers and separate adjustable pressure necks for each
wire, various sizes of wire may be straightened at the same time, and when one end
has run off another may be put on without having to stop the machine.
To the shaft B is imparted simultaneously a rotary and reciprocating or back-
wards and forwards end wise motion, by means of a chain N, and chain wheels P
and P, operated by the driving shaft R of the machine.
The chain wheel P is attached to a gear wheel V which is loose upon the
shaft R, this gear wheel V gears with a double gear wheel V, upon a stud V³, by
means of which the speeding of the driving shaft R and the straightening shaft B
may be independent of each other.
Upon this driving shaft is also a cam S having preferably three, four or more
ways; in the groove of this cam works one end of an adjustable forked pivotted
lever T, the other end of which operates within a grooved bush or collar U, upon
the shaft B, and as the cam S revolves, it imparts (by means of the pivotted
lever T) the necessary backwards and forwards end wise or rubbing motion to the
shaft B.
The adjustability of the said fork lever T is effected by means of a fulcrum
joint on the fork lever T is a plate T, adjustable along the slot T' of the lever,
and attached to this lever by means of bolts 13, the cross bar X is also provided
with a slot T, a stud bolt T, passing through the cross bar X, stud hole in
plate T, and forked lever T, allows an adjustment of the parts and giving any
desired amount of lateral movement to the horizontal shaft B.
Wincels W and blocks W for holding and receiving the wire are arranged in
any suitable manner, upon a suitable frame or frames.
By lengthening the hardened steel bosses and increasing the number of pressure
necks and levers, any number of wires may be passed through the machine.
A number of machines of any size may be mounted on one gantry.
The oil upon the wire can be taken off it by passing the said wire through
emery, indiarubber, or by other suitable means.
Or it may be passed through pegs if required on its passage to the block or
winder.
·
The blocks or winders may be operated and speeded as desired by means of a
pulley X, and rope Y, upon the driving shaft R.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, I declare that what I claim is :-
1. Straightening wire by passing it between a boss or bosses D, upon a shaft B,
and separate independent pressure necks F for each wire, the shaft B having
imparted to it simultaneously a rotary and reciprocating or rolling motion, or the
equivalent, as and for the purposes shown and described.

page_text: 2. In machinery for straightening continuous lengths of wire, the employment of
separate steel necks F for each wire, independent pressure being put upon the wire
by the said necks F, as it passes between them and the steel bosses D of the
shaft B, a rotary and a reciprocating or rubbing motion being simultaneously
imparted to the said shaft and bosses, substantially as and for the purposes shown
and described.
3. In machinery for straightening wire the use and employment of eccentric hand
levers L, fulcrum levers G, pressure springs H, springs M and studs M' for putting
on and taking off the pressure of the necks F from the bosses D of the shaft B,
so that any one wire can be stopped, taken out or replaced, without stopping the
machine, substantially as shown and described.
4. In machinery for straightening wire, the use and employment of the shaft B
in fixed bearings C, the shaft having steel bosses D, pressure necks F, in boxes E,
levers G, springs H, levers L, springs M, studs M', chain N, and chain wheels P
and P, operated by the driving shaft R, the cam S operating the lever T, which
imparts the reciprocating or rubbing motion to the shaft B, substantially as shown
and described.
