Improvements in or relating to Combined Shaping and Boring
Machines.
I, WILLIAM HENRY BAXTER, of 71, Gelderd Road, Leeds, in the County of
York, Engineer, do hereby declare the nature of this invention to be as follows:-
This invention has reference to combining a shaping machine and a boring
machine, such as are used in the working of metals, or in other words to adapt
a shaping machine to perform the double operations or functions either simul-
taneously or separately.
Hitherto the operations of shaping and boring have been performed on separate
and distinct machines, thus entailing considerable loss of power, as well as of
labour and time.
Now the object of this invention is to prevent this loss of power, labour, and
time, and to enable shaping and boring to be performed or accomplished prefer-
ably simultaneously, but, should occasion so require, also separately.
According to this invention I attach or connect a boring bar or mandrel to or
on the end of a portion of the horizontal work holder, to which a rotary motion.
may be imparted when required, of a shaping machine, preferably, though not
necessarily so, provided with, say, two tables adjustable on the bed of the machine,
and say, one adjustable reciprocating tool holder. Or the boring bar may be sub-
stituted for and in place of the said horizontal work holder. In either case the
boring bar is carried in suitable bearings. A suitable hinged or other work carrier
or holder, capable of being traversed either backwards or forwards as required,
may be mounted upon a suitable slide attached to or upon one of the adjustable
tables of the machine or upon a separate table or stand,-adjustable or otherwise,
provided for its reception.
A rotary motion may be imparted to the boring bar or mandrel by the ordinary
means now employed for actuating the rotary work holder, or preferably motion
is imparted from any suitable source to a counter shaft,-mounted in bearings
fixed to the bed of the machine,-provided with a coned or other pulley, and from
thence by a belt to a second counter-shaft on which is mounted and fixed a worm
arranged to engage with a worm wheel or other gearing mounted and fixed on
the end of the boring bar or mandrel.
The required motion for automatically rotating the traversing screw of the
work carrier or holder may be obtained preferably from the boring bar or mandrel
by an arrangement of a number of spur wheels whereby the speed or traverse
may be varied as required, or the said screw may be actuated by suitable gearing
direct from one of the herein-before mentioned counter shafts.
Other portions of the shaping machine not particularly described and the means
for operating the moving parts may be of the usual and well known construction.
Dated this First day of April 1898.

Improvements in or relating to Combined Shaping and Boring
Machines.
1. '
I, WILLIAM HENRY BAXTER, of 71, Gelderd Road, Leeds, in the County of
York, 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 has reference to combining a shaping machine and a boring
machine, such as are used in the working of metals, or in other words to adapt
a shaping machine to perform the double operations or functions either simul-
taneously or separately.
Hitherto the operations of shaping and boring have been performed on separate
and distinct machines, thus entailing considerable loss of power, as well as of
labour and time.
Now the object of this invention is to prevent this loss of power, labour, and
time, and to enable shaping and boring to be performed or accomplished, that is,
both operations, preferably simultaneously, but, should occasion so require, also
separately.
In the drawings hereunto annexed:-
Fig. 1 is a front elevation, Fig. 2 an end elevation, and Fig. 3 a plan looking
at the top of a machine constructed according to this invention.
Fig. 4 a sectional elevation of work carrier on line x Fig. 3.
Like parts in all the views are marked with similar letters of reference.
A is the gantry or bed of the machine, B the slide upon which the reciprocating
head (not shown in the drawings) of the shaping machine works. C is one of the
work supporting tables capable of vertical adjustment in the slide D which is fixed
to the gantry A by T headed bolts passing into the slots d. The slide D may be
adjusted in a horizontal direction at pleasure. E is the shaft that conveys a
rotary motion to the horizontal work holder through worm wheel F, worm G, and
shaft H. I is the usual cone pulley mounted upon shaft J.
All the above parts are of the usual construction, and motion is imparted to the
shaping head in the usual manner.
According to this invention I attach or connect a boring bar or mandrel K to
or on the end of a portion of the horizontal work holder, not shown in the drawings,
but which may be a continuation of shaft E, to which a rotary motion may be
imparted when required, of a shaping machine, preferably, though not necessarily
so, provided with, say two tables, (of a similar construction to table C), adjustable
on the bed of the machine, and on which the adjustable reciprocating tool holder
works. Or the boring bar may be substituted for and in place of the said hori-
zontal work holder as shown in the drawings, in which case the mandrel K is made
to be a continuation of shaft E. In either case the boring bar, that is mandrel K,
is carried in suitable bearings C¹.
A suitable hinged or other work carrier or holder L capable of being traversed
either backwards or forwards as required by screw M, nut N, and train of spur
gearing may be mounted upon a suitable slide C² attached to or upon one of
the adjustable tables C of the machine or upon a separate table or stand,—adjust-
able or otherwise, provided for its reception.
A rotary motion may be imparted to the boring bar or mandrel K by similar
means to that ordinarily employed for actuating the rotary work holder, except
that the said motion is made continuous, instead of intermittent, say, by suitable
gearing, or preferably motion is imparted from any suitable source such as, say,

page_text: to a cone pulley I mounted on shaft J, and from thence through pulley J¹ also on
shaft J, by a belt J, to pulley P¹ on counter shaft P,--mounted in bearings fixed
to the bed or gantry A of the machine. The counter-shaft P is also provided with
a coned or other pulley P³, from which motion is transmitted by a belt P³ to a
pulley G¹ on a second counter-shaft H on which is mounted and fixed the worm G
arranged to engage with the worm wheel F or other gearing mounted and fixed
on the shaft E to which the end of the boring bar or mandrel K is attached.
The required motion for automatically rotating the traversing screw of the work
carrier or holder L is obtained preferably from the boring bar or mandrel K by
an arrangement of a number of spur wheels which forms the train O, whereby the
speed or traverse may be varied as required, or the said screw M may be actuated
by suitable gearing direct from one of the herein before mentioned counter shafts.
Other portions of the shaping machine not particularly described and the means
for operating the moving parts may be of the usual and well known construction.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is;-
In a combined shaping and boring machine, the combination of a hinged or
other work holder or carrier L mounted in a slide C2 upon an adjustable table C
with a horizontal boring bar or mandrel K mounted in bearings over said table C,
and the means for automatically rotating the boring bar or mandrel and traversing
the hinged or other work carrier in the manner substantially as described and
illustrated and for the purposes set forth.
Dated this Twenty-second day of December 1898.
