IMPROVEMENTS IN MACHINERY FOR TURNING, BORING, MILLING, PLANING, SHAPING, SLOTTING, AND DRILLING METALS AND OTHER MATERIALS." PROVISIONAL SPECIFICATION
Year: 1880

page_text: LETTERS PATENT to Joseph Evans, of the Firm of Joseph Evans and Sons,
of Wolverhampton, in the County of Stafford, Hydraulic and General
Engineers, for an Invention of "IMPROVEMENTS IN MACHINERY FOR
TURNING, BORING, MILLING, PLANING, SHAPING, SLOTTING, AND DRILLING
METALS AND OTHER MATERIALS."
PROVISIONAL SPECIFICATION left by the said Joseph Evans at the Office
of the Commissioners of Patents on the 24th December 1880.
JOSEPH EVANS, of the Firm of Joseph Evans and Sons, of Wolverhampton, in
the County of Stafford, Hydraulic and General Engineers. "IMPROVEMENTS IN
MACHINERY FOR TURNING, BORING, MILLING, PLANING, SHAPING, SLOTTING, AND
DRILLING METALS AND OTHER MATERIALS."
My Invention has reference to those parts of the said machinery by which the
adjustment of the material or article to be operated upon is effected, and my said
Invention consists of the construction and arrangement or combination of parts
herein after described for effecting the said adjustment.
In the ordinary method of adjustment adopted in the said machinery the article
or material to be operated upon is raised to a proper height by moving the support
or holder carrying it vertically.
In constructing the adjusting mechanism according to my Invention I employ an
inclined plane, on which the support or holder carrying the article or material to
be operated upon slides. The underside of the support or holder is inclined at the
same angle as the inclined plane on which it travels, so that as the said support or
holder travels up or down the inclined plane its upper surface is maintained in a
horizontal position or parallel to the base of the machine. The motion of the
support or holder on the inclined plane may be effected either by a worm and
worm wheel, or by a screw and screw box, or by a rack and pinion or other like
mechanism.
By my improvements the adjustment of the article or material to be operated
upon in the said machinery is effected with great facility and nicety.
My Invention is applicable to machinery in which the boring bar or other bar
has a traversing motion, as well as to those in which the saddle has a traversing
motion.

by the said Joseph Evans in the Great Seal Patent Office on the 17th June
1881.
JOSEPH EVANS, of the Firm of Joseph Evans and Sons, of Wolverhampton, in
the County of Stafford, Hydraulic and General Engineers. "IMPROVEMENTS IN
MACHINERY FOR TURNING, BORING, MILLING, PLANING, SHAPING, SLOTTING, AND
DRILLING METALS AND OTHER MATERIALS."
My Invention has reference to those parts of the said machinery by which the
adjustment of the material or article to be operated upon is effected, and my said
Invention consists of the construction and arrangement or combination of parts
herein after described for effecting the said adjustment.
In the ordinary method of adjustment adopted in the said machinery the article
or material to be operated upon is raised to a proper height by moving the support
or holder carrying it vertically.
In constructing the adjusting mechanism according to my Invention I employ
an inclined plane, on which the support or holder carrying the article or material
to be operated upon slides. The underside of the support or bolder is inclined at
the same angle as the inclined plane on which it travels, so that as the said support
or holder travels up or down the inclined plane its upper surface is maintained in
a horizontal position or parallel to the base of the machine. The motion of the
support or holder on the inclined plane may be effected either by a worm and
worm wheel, or by a screw and screw box, or by a rack and pinion or other like
mechanism.
Figure 1 of the accompanying Drawing represents in side elevation, and Figure 2
in end elevation, a boring lathe containing my improvements; Figure 3 is a plan
of the lathe with the holder or table removed, showing the inclined traversing
saddle, upon which the said holder or table is supported; Figure 4 represents a
half plan of the holder or table detached from the lathe.
In the lathe represented the saddle has a traversing motion on the bed of the
machine, and the boring bar has a rotatory motion.
a is the traversing saddle, the upper side of which is an inclined plane. The
said saddle has a traversing motion given to it on the bed of the machine by a rack
and pinion in the ordinary way; b is the rotating boring bar worked in the ordinary
way. On the said inclined saddle the support or holder d slides, the said support
carrying the table e, on which the article or material to be operated upon is fixed.
The underside of the support or holder d is inclined at the same angle as the
inclined upper side of the traversing saddle a, as represented in Figure 1, where it
will be seen that as the said support or holder d travels up or down the inclined
plane of the saddle a the upper surface of the said holder is maintained in a
horizontal position or parallel to the base of the machine. The height and position
of the article or material carried by the table e can thus be readily and accurately
adjusted.
.
The adjustment of the position of the inclined holder or support d upon the
inclined upper side of the saddle a may be effected by the arrangement of parts
shown in the Drawing. The said arrangement consists of a worm f, turned by a
winch placed on the square end f' of the axis of the said worm. The worm f
engages with the worm wheel h, the boss of which is made into a screw box, which
works on the fixed inclined screw . The boss of the worm wheel h engages with
the bracket k on the underside of the holder or support d. By turning the worm ƒ
rotatory motion is given to the worm wheel h, which rises and falls on the screw i,
carrying with it the bracket k and the support or holder d. The holder d is locked
in any position to which it may have been brought by the locking screw g.
The table e of the holder & may be turned round on the pivot represented.

page_text: The traversing motion of the holder or support d upon the inclined saddle a may
be effected by a rack and pinion or other equivalent mechanism.
By my improvements the adjustment of the article or material to be operated
upon in the machinery is effected with great facility and nicety.
Although I have represented my Invention as applied to a boring lathe, in which
the boring bar has a rotary motion, and the saddle has a traversing motion, yet my
Invention may be applied to boring lathes in which the boring bar has a traversing
motion, and to machinery in general for turning, boring, planing, milling, shaping,
slotting, and drilling metals and other materials.
Having now described the nature of my Invention, and the manner in which the
same is to be performed, I wish it to be understood that I claim as my Invention
of "Improvements in Machinery for Turning, Boring, Milling, Planing, Shaping,
Slotting, and Drilling Metals and other Materials,"
Constructing those parts of the said machinery by which the vertical adjustment
of the material or article to be operated upon is effected in the manner herein
before described and illustrated in the accompanying Drawing, that is to say,
inclining the upper side of the saddle or platform supporting the sliding holder
carrying the article or material to be operated upon, and inclining the underside of
the said holder at the same angle as the inclined upper side of the saddle or platform
for the purpose and substantially as described and illustrated.
In witness whereof, I, the said Joseph Evans, have hereunto set my hand
and seal, this Fifteenth day of June, in the year of our Lord One thousand
eight hundred and eighty one
Witness,
C. H. ARTHUR SMITH,
