An Improved Cold Iron and Steel Sawing Machine.
JOSEPH HILL George Street Engineering Works, Derby, Engineer, ISAAC HILL
George Street Engineering Works, Derby, Engineer, do hereby declare the nature of
this invention to be as follows:-
:-.
This invention relates to a vertical type of Cold Iron and Steel Sawing machines
carrying a saw which revolves in a horizontal plane and arranged to be raised or
lowered and worked to and fro at any desired altitude, according to the work required
to be operated upon. We form a massive pillar or standard, with large base plate.
Down the front face we form flat faces, and vees, similar to an ordinary lathe bed;
on the top of this pillar or standard, are fixed two brackets, and so placed to carry the
main horizontal driving shaft; near to one end of this said shaft are the various
pulleys for driving the machine, and at the other end, is a bevil pinion, geared in a
bevil wheel, which is provided with a long boss and a recess having been turned in
it to fit a bearing bracket, which stands out at right angles to the main horizontal
driving shaft, and so arranged that the wheel shall be free to revolve in this said
bearing bracket. Through this wheel with long boss, is passed a shaft which when
fixed is in a vertical position, having a key-way cut in its whole length; the wheel
being previously provided with a feather-key, so that wherever the wheel may be on
this vertical shaft the wheel will not revolve without it revolves the shaft with it; at
one end of this shaft is arranged a foot-step, this footstep is fixed on to the slide bed
which is provided, and which carries the saw spindle saddle or carriage. This slide
bed is fitted with vees and strips corresponding with those already spoken of on the
Pillar or Standard. This slide bed is made to slide the whole length of the faces and
vees that are provided on the said Pillar or Standard. This said slide bed is also
provided with surfaces and vees, and upon these surfaces and vees moves the saddle
made the desired shape, which carries the saw spindle and to which is attached the
Saw by Hill's Patent No. 14429/85. The driving of the Saw Spindle is from a
principal shaft in the slide bed, and this driving is an arrangement of gearing as
described in our application for Patent No. 11758 Aug. 15/88. All the feed of cut
motions, quick return motions etc. are obtained from this principle shaft by our usual
method of gearing. This principal shaft is driven by a bevil wheel, which is attached
to the vertical shaft end of the slide bed; it being geared with another wheel attached,
and fixed on the vertical shaft just above the foot step before referred to, and which is
secured to the end of this said slide bed. The raising of this slide bed to which all
the parts of the machine actually necessary for use whilst sawing is being proceeded
with, is done by means of a screw, which passes down the whole length of the pillar
or standard, and through a nut that is fitted and secured in one side of the slide bed.
This raising or lowering screw is driven by one of the pulleys placed in such a position
that the driving belt may be used for raising or lowering, as desired. As this raising
screw must revolve left & right hand, an arrangement of gearing is necessary, as one
driving belt is arranged to drive the saw, as well as raise and lower the machine. To
this said pulley is attached a sleeve, or long boss, and having at proper positions two
wheels cast with it, one intended for raising, the other intended for lowering. Through
this sleeve runs the main horizontal shaft. We also provide two brackets which are
fixed, and intended to carry a horizontal counter lifting shaft, these being fixed at
the top of the pillar or standard, in line with th centre of the vertical lifting screw;
on this horizontal counter lifting shaft, are fitted two sets of friction wheels, having
spur wheels cast on one side of each, and are geared with the wheels previously
mentioned, which are cast with the sleeve or long boss, to which the pulley is attached

page_text: to. The reverse motion of the screw is given and attained by one pair of wheels
having an intermediate geared between the wheel on sleeve or long boss, and the
wheel which is cast on one of the friction wheels.
On this said countershaft, and fixed between the two friction clutches are a pair of
mitre wheels, one being on this said countershaft and the other on the top of the
vertical raising or lowering screw, so that which ever direction the counter lifting
shaft is revolved by the friction wheels, the said vertical screw will be revolved accord-
ingly. The friction gear is operated by means of levers, and screw with hand-wheel
attached; so that by revolving the screw with hand-wheel attached either one way, or
the other it moves the levers and thus puts the friction clutches in or out of gear as
desired for lowering or raising the saw. There is also an arrangement of striking
gear for moving the belt on to the pulley for working the sawing portion of the
machine, or for moving on to the loose pulley provided; when the whole of the machine
is required to be stationary; or for moving on to the pulley for lifting or lowering as
described. The machine is also provided with a small centifugal pump for forcing
lubricant on to the saw whilst it is cutting.

COMPLETE SPECIFICATION.
An Improved Cold Iron and Steel Sawing Machine.
JOSEPH HILL, George Street Works, Derby, Engineer, and ISAAC HILL,
George Street Works, Derby, Engineer, do hereby declare the nature of this
invention 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 a vertical type of Cold Iron and Steel Sawing machine,
carrying a Saw which revolves in an horizontal plane, and arranged to be raised or
lowered, and worked to and fro, at any desired altitude, according to the work required
to be operated upon.
We form a massive pillar or standard A, Sheet I & II, with large base plate A¹
Sheet I & II; down the front face we form flat faces and vees B, B Sheet I & II,
similar to an ordinary lathe bed; on the top of this pillar or standard A Sheet I & II,
are fixed two brackets C, C Sheet I & II, and so placed to carry the main horizontal
driving shaft D Sheet I & II, near to one end of this said shaft are the various
pulleys a, E, a' Sheet I & II, for driving the machine; and at the other end is a
bevil pinion F Sheet 1 geared in a bevil wheel F¹ Sheet I & II, which is provided
with a long boss F2 Sheet I & II, and a recess having been turned in it to fit a
bearing bracket G Sheet I & II which stands out at right angles to the main horizontal
driving shaft D Sheet I & II, and so arranged that the wheel shall be free to revolve
in this said bearing bracket G Sheet I & II. Through this wheel F¹ Sheet I & II
with long boss is passed a shaft H Sheet I & II, which when fixed is in a vertical
position, having a keyway cut in its whole length H Sheet I, the wheel being
previously provided with a feather key H2 Sheet I, so that wherever the wheel may
be on this vertical shaft H Sheet I & II, the wheel F¹ Sheet I & II will not revolve
without it revolves the shaft H Sheet I & II with it, at one end of this said shaft is
arranged a footstep i Sheet I, this footstep is fixed on to the slide bed J Sheet 1
which is provided and which carries the saw spindle carriage, or saddle, J' Sheet I & II.
This slide bed J Sheet I is fitted with vees and strips B₁ & B2 Sheet I & II corre-
sponding with those B, B Sheet I & II already spoken of; on the pillar or standard A
Sheet I & II this slide bed J Sheet I is made to slide the whole length of the faces
and vees that are provided on the said pillar or Standard A Sheet 1 & II.
This said slide bed J Sheet I is also provided with surfaces, and vees, K & K¹
Sheet I & II, and upon which moves the saw spindle carriage, or saddle J' Sheet I & II

page_text: made the desired shape, which carries the saw spindle L Sheet I & II, and to which
is attached the saw L¹ sheet I & II by Hill's Patent No. 14429/85. The driving of
the saw spindle is from a principle shaft M Sheet I, in the slide bed J Sheet I and
this driving is an arrangement of gearing as described in our Patent No. 11758/88.
All the feed of cut motions, quick return motions etc., are obtained from this principle
shaft by our usual and well known method of gearing. This principle shaft M
Sheet I is driven by a bevil wheel n' Sheet I, which is attached to the vertical shaft
end of the slide bed J Sheet I; it being geared with another wheel n² Sheet I,
attached, and fixed on the vertical shaft H Sheet I, just above the footstep i Sheet I
before refered to, and which is secured to the end of this said slide bed J Sheet 1.
The raising of this slide bed J Sheet I & II, to which all the parts of the machine
actually necessary whilst sawing is being proceeded with, is done by means of a
screw N Sheet I & II, which passes down the whole length of the pillar, or standard A
Sheet I & II and through a nut that is fitted, and secured in one side of the slide
bed J Sheet I & II. This raising or lowering screw N Sheet I & II is driven by the
pulley a Sheet I, placed in such a position that the driving belt may be used for
raising or lowering as desired; as this raising screw N Sheet I & II must revolve
left, and right hand, an arrangement of gearing is necessary, as one driving belt is
arranged to drive the saw, as well as raise, & lower the part of machine which
carries the saw L' Sheet I & II.
To this said pulley a Sheet I is attached a sleeve, or long boss O Sheet I and having
at proper positions, two wheels 6 & 6' Sheet I cast with it, one intended for raising,
the other intended for lowering. Through this sleeve runs the main horizontal
shaft D Sheet I & II. We also provide two brackets P Sheet I & II which are
fixed & intended to carry a horizontal counter lifting shaft Q sheet I, these being fixed
at the top of the pillar, or Standard A Sheet I, in line with the centre of the vertical
lifting screw N Sheet I, on this horizontal counter lifting shaft Q sheet I, are fitted
two sets of friction wheels R & R sheet I, having spur wheels & r¹ Sheet I cast on
one side of each, and are geared with the wheels 6 & 6 Sheet I previously mentioned,
being cast with the sleeve or long boss O Sheet I which the pulley a Sheet I is
attached to. The reverse motion of the screw N Sheet I is given, and attained by
one pair of wheels b₁ & ¹ Sheet I, having an intermediate wheel geared 2 Sheet I
between the wheel b¹ Sheet I on sleeve, or long boss O Sheet I & the wheel which is
cast on one of the friction wheels R¹ Sheet I. On this said counter shaft Q Sheet I, and
fixed between the two friction clutches R & R' Sheet I, are a pair of mitre wheels S & S¹
Sheet I one being fixed on this said counter shaft Q Sheet I, and the other on the top
of the vertical raising, or lowering screw N sheet I, so that which ever direction the
counter lifting shaft Q sheet I is revolved by the friction wheels R & R' Sheet I, the
said vertical screw N Sheet I will be revolved accordingly. The friction gear R & R¹
Sheet I is operated by means of levers T sheet I, and screw T¹ Sheet I, with hand
wheel T sheet I attached, so that by revolving the screw T¹ Sheet I with hand
wheel T2 sheet I, either one way, or the other, it moves the levers T sheet I, and thus
puts the friction clutches R2 & R³ sheet I in or out of gear as desired for lowering or
raising the saw.
There is also an arrangement of striking gear U Sheet I & II, for moving the belt
on to the pulleys a, E, a¹ Sheet I & II, for working the sawing portion of the machine,
or for moving on to the loose pulley E Sheet I provided, when the whole of the
machine is required to be stationary, or for moving on to the pulleys a, E, al
Sheet I, for lifting or lowering as described. A balance weight V Sheet I to give
an equilibrium to the weight of the parts to be lifted is provided, and atttached
by a wire rope X Sheet I running over suitable grooved pulleys V¹ Sheet I.
The machine may be provided with pump for forcing, or lifting lubricant on to
the saw whilst it is cutting.
The machine is also applicable for a useful form of milling machine, by simply
removing the saw blade I Sheet I & II, and placing on saw spindle L Sheet I & II
a milling tool

page_text: Having now, particularly described, and ascertained the nature of our said Inven-
tion, and in what manner the same is to be performed, we desire it to be understood
that we do not restrict ourselves to the precise details now given, as in some
cases mechanical equivalents may be employed without departing from the
principles, and leading characteristics of our Invention: but we claim as our
