PROVISIONAL SPECIFICATION.
Improvements in the Method of and Means or Apparatus for
Compressing, Straightening, and Brightening or Polishing Iron,
Steel, and other Metals for Shafting, and Bars, Rods, or the
like of any suitable Section.
We GEORGE HALES of 16 Lillies Terrace, Grange Street, Puddler, CAUTLEY
TUTILL, of 16 Princes Dock Street, Restaurant Proprietor, and CHARLES
GREENSIDES, of 5 Posterngate, Iron Merchant, all in Hull in the County of
Yorks do hereby declare the nature of this invention, to be as follows :—
The object of our invention is to provide an improved method of and means or
apparatus for compressing, straightening and brightening or polishing iron, steel,
or other metals, for the purpose of shafting or the like, and also any suitable section
of rods, bars or the like.
Our invention relates to compressing, straightening, and polishing or brightening
shafting, or the like, by drawing or pushing it through dies. For the purpose of
effecting this object we may employ a machine having dies fitted into standards or
pedestals at the ends of the machine. A leading screw runs along the middle of
the machine and is moved from end to end by means of preferably a gear wheel
mounted at or near the centre of the machine. The ends of the aforesaid screw
are provided with enlarged parts with side pieces, the enlarged parts receive the
shafting or the like to be operated on, being provided with holders for that purpose..
A crosshead is fixed to the ends of the screw and slides on guide bars to keep the
movement of the screw true this crosshead slides on the guide bars which run from:
the centre pedestals to the ends of the machine, and the enlarged parts may be
made of such a size that they move between such guide pieces and are thus rendered
true in their movement. The machine is actuated by means of clutches or crabs
driven by straps and pulleys or other suitable means, the clutches or crabs being
connected to a spur wheel or the like, which gears with or runs in frictional contact
with the wheel which moves the screw backward and forward, this latter wheel is
preferably mounted between two pedestals and is provided with an inner box or
bush internally threaded to fit the thread of the longitudinal screw before mentioned:
as this wheel revolves by contact with the wheel connected to the clutches or crabs,
the said screw is moved backward and forward by means of the thread on the
screw fitting the internal thread in the box of the wheel, by this means the shafting,
bars or the like are continually being pulled in and pushed out through the dies
at the ends of the machine, which compresses, straightens and brightens or polishes*
them. If desired we may use other suitable means for passing the shafting or the
like to be polished through the dies instead of using the aforesaid screw, as for
instance chains or the like, hydraulic, or pneumatic machinery.

Our invention relates to compressing, straightening and polishing or brightening
shafting rods or the like by drawing it through dies.
For the purpose of effecting this object we employ a machine having dies fitted
into standards or pedestals A, A' at the ends of the machine.
These standards or pedestals have feet B, attached for holding down purposes,
the two end standards A A' being provided in the centre with die holders C (see
Fig. 4) one to each standard, these die holders C take the dies for polishing or the
like the rods bars or shafting D to be operated upon, such die holders C have set
screws E within bosses El for the purpose of regulating or setting the dies.
The two middle standards A2 and A3 are constructed with one side B₁ of the
foot B to project further than the feet of the end standards, these projecting feet B
take brackets or stands F, F1 and for carrying the shafting G for the gear wheel H,
pulleys I, I and clutches or crabs J, Ji and these middle standards A2 A³ are
provided with lugs X to allow of them being bolted together (see Fig. 2).
The said gear wheel H is preferably of the spur type, being keyed on a shaft G
bearing on two brackets F, F bolted to the feet B' of the middle standards A2 A³
such shaft taking also the fast half of each of the clutches or crabs J J'.
A leading screw L, runs along the centre of the machine and is moved from
end to end by means of preferably a gear wheel M mounted at or near the middle
of the machine. The, ends of the aforesaid, screw are provided with enlarged
parts N, N', with side pieces, the enlarged parts N, N', receive the shafting D or
the like to be operated on, being provided with holders for that purpose.
Crossheads 0, 0, are fixed at or near the end of the screw L and slide on
guide bars P, P1, P2, to keep the movement of the screw true, these crossheads O, O'

page_text: slide on the guide bars P, P1, P2 which run from the centre standards or
pedestals A2, A3, to the ends of the machine, and the enlarged parts N N' may be.
inade of such a size that they move between such guide pieces P P P and are
thus rendered true in their movement. The machine is actuated by means of the
aforesaid clutches or crabs J, J', driven by straps Q. Q', and pulleys I, I', or
other suitable means.
If desired there may be four pulleys two of different sizes for each end of the
machine to allow of the speed of the gear wheels and serew being regulated, the
clutches or crabs being connected to a spur or gear wheel H or the like which
gears with the gear wheel M which moves the screw L backward and forward,
this latter wheel M is mounted between the two pedestals A and A and is
provided with a square hole to take the squared part of an inner box or bush R
internally threaded to fit the thread of the longitudinal leading serew L, before
mentioned, the aforesaid box being provided with collars S for the purpose of
keeping the wheel M in position, as this wheel M revolves by contact with the
wheel H connected to the clutches or crabs J J the said screw L is moved back-
ward and forward by means of the thread on the screw fitting the internal thread
in the box R of the wheel M, by this means the shafting bars or the like D. are
continually being pulled in through the dies (see Fig. 4) at the ends of the.
machine which compresses, straightens and brightens or polishes them.
An arrangement consisting of two levers T, T', working in a groove in the loose-
end of the clutches J, J', is employed for putting the clutches in gear and for
throwing them out of gear to stop the machine at the end of each pull, these levers
are pivotted U preferably to the frame of the machine, one lever T projecting
inwardly and the other T outwardly. These levers have forked ends to clip the
crab or clutch the forked end of one lever being provided with projections a (see
Figs. 5 and 6), the inside projections work in a groove in the crab or clutch, the
prongs of the cutwardly projecting lever T' are split to take the outside projections.
in the lever T, by this means the levers are at liberty to be moved from right to
left or vice versa. A projection or arm V with forked end Vis connected preferably
to each crosshead 0, 0₁ as the screw L moves from one end of the machine to the
other the forked end of the arm V on the crosshead moving towards the centre of
the machine comes in contact with the inwardly projecting lever T actuating the
clutch that is, supposing the screw is moving from left to right of the machine the
arm V would come in contact with the pivotted lever T connected to the loose end
of the clutch J on the left hand side, this would move such loose part of the clutch
away from the fast part with which it had engaged, and the fast and loose parts.
on the right hand side would then be thrown into contact by means of the outwardly
projecting lever T¹ this is done by the attendant who puts the clutches into gear,
for working, but such clutches are thrown out of gear automatically by the arms.
attached to the crossheads.
The action is as follows:-One of the pulleys at one end say the pulley I at.
the left hand side, is set in motion by means of a belt, cord or the like connected
to any suitable driving machinery, the loose clutch J mounted on the same shaft
as the said pulley I is moved towards the fast part mounted on the same shaft G
as the gear wheel H when the fast and loose parts of such clutch J come in contact
they engage with each other and thus turn the aforesaid gear wheel H which also.
drives the larger gear wheel M having an internal threaded box R fitting the
thread of the leading screw L, as this large gear wheel M is revolving in the
direction of the arrow it causes the leading screw L to move from lett to right.
of the machine when the screw has moved as far as desirable in the direction
left to right the arm V mounted on the crosshead O comes in contact with the
inwardly projecting lever T this throws the loose end of clutch out of contact with
the fast part, whilst the screw is moving the bar or the like D at the left hand
side is being drawn through the die and polished, brightened and hardened.
The machine is stopped when the clutch is thrown out of gear, a bar or shaft D..
is placed in the holder N at the right hand side of the machine the fast and.

page_text: loose parts of the clutch J¹ on the right hand side of the machine are brought
into contact and the screw L moves back from right to left pulling the rod or
the like D through the die at the right hand end of the machine the arm V
connected to the crosshead O' at the end throwing the clutch J1 out of gear,
when the screw L has gone far enough, in the same manner as the one at the
left hand end before described.
Having now particularly described and ascertained. the nature of this inven-
tion and in what manner the same is to be performed we declare that what we
claim is
1. A machine for compressing, straightening, and brightening or polishing
shafting, bars, rods, or the like, consisting of a longitudinal screw L, mounted
between guide bars P. P1 P2 and moved by an internally threaded gear wheel M,
driven by a gear wheel H, operated by means of crabs or clutches J J, actuated
by pulleys I, I driven by means of cords, straps, or the like from any suitable
driving machinery, and pedestals for taking the dies and supporting the gear
wheels in the manner and for the purposes, substantially as shown and described.
2. Drawing shafting, bars, or the like through dies for the purpose of
straightening, brightening, or polishing and compressing in the manner and for
the purposes substantially as shown and described.
3. In polishing machines a die holder having bosses to take set screws for the
purpose of regulating the setting of the die in the manner and for the purposes
substantially as shown and described.
