Year: 1864

page_text: LETTERS PATENT to William Bayliss, of the Firm of Bayliss, Jones, and
Bayliss, of Monmore Green, Wolverhampton, in the County of Stafford,
and Gracechurch Street, in the City of London, Iron Fencing Manufac-
turers, for the Invention of "CERTAIN IMPROVEMENTS IN MACHINERY FOR
PUNCHING, PRESSING, AND SHEARING METALS."
PROVISIONAL SPECIFICATION left by the said. William Bayliss at
the Office of the Commissioners of Patents, with his Petition, on the
3rd November 1864.
I, WILLIAM BAYLISS, of the Firm of Bayliss, Jones, and Bayliss, of Mon-
more Green, Wolverhampton, in the County of Stafford, and Gracechurch
Street, in the City of London, Iron Fencing Manufacturers, do hereby declare
the nature of my said Invention for " CERTAIN IMPROVEMENTS IN MACHINERY FOR
PUNCHING, PRESSING, AND SHEARING METALS," to be as follows (that is, to say) :-
My improvements may be applied to the machines already in use if neces-
sary, and are confined entirely to the manner of actuating the part that carries
the punch, shear, or die, and which parts in the machines as now constructed
are constantly at work by means of the eccentric in connection with the gear
and fly wheels as they revolve or are in motion, and this continuous action of
the punch, shear, or die is objectionable for a variety of purposes for which
such mechanical appliances are necessary; and my improvements are for
obviating this defect, and consist in forming or applying in front of the moving
bolster that carries the tools a metal support with projections at the end for.

page_text: guiding a thick piece of steel or iron equivalent to the throw of the cam, and
to this piece of metal a small handle is attached for the convenience of the
workman. The use of this will be hereafter referred to. I allow sufficient
room for the cam (which actuates the punch, shear, or die, as they may be
respectively applied to such machine) to freely revolve after elevating the
punch, die, or shear, and which will remain in that position until the attendant
has placed the work in position and desires to call into action the punch,
shear, or die, which he does by sliding in beneath the cam the moveable bed
or piece of metal before referred to, and as the cam passes over its surface, it
depresses this with the bolster and tool, aud performs the operation desired;
and as the cam continues to revolve, so the reverse motion will take place by
its again lifting up the bolster with the tool, where it will remain by the
attendant pulling the piece of metal or moveable bed forward to allow the
cam to freely revolve; and when the workman has again placed his work in
position, either for punching, shearing, or pressing, according to the tool or
tools that may be fixed in the machine, he has only to place the moveable
bed under the cam to effect this object. These improvements, though simple,
are of great benefit and use, for many descriptions of work on which such
machinery is used, and may be constructed to work upwards or downwards,
that is, in each or both directions if required, and may be set up vertically,
horizontally, or in any angular direction.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Bayliss,. in the Great Seal Patent Office on the
3rd May 1865.

condition (amongst others) that I, the said William Bayliss, by an instrument
in writing under my hand and seal, should particularly describe and ascertain the
nature of the said Invention, and in what manner the same was to be performed,
and cause the same to be filed in the Great Seal Patent Office within six
calendar months- next and immediately after the date of the said Letters
Patent.
.
:.
NOW KNOW YE, that I, the said William Bayliss, do hereby declare
the nature of my said Invention, and in what manner the same is to bo
performed, to be particularly described and ascertained in and by the following
statement:-
My improvements may be applied to the machines already in use if neces-
sary, and are confined entirely to the manner of actuating the part that carries
the punch, shear, or die, and which parts in the machines as now constructed
are constantly at work, by means of the eccentric, in connection with the
gear and fly wheels as they revolve or are in motion; and this continuous
action of the punch, shear, or die, is objectionable for a variety of purposes
for which such mechanical appliances are necessary, a great deal of scrap and
other injurious consequences being unavoidably produced with the machines
as ordinarily constructed. And my improved arrangement entirely obviates
these objectionable and expensive results, and consist in simply forming or
applying on the front of the moving bolt or slide that carries the punch,
shear, or die a metal support with end and side projections for guiding a
picce of steel or iron of an equvalent thickness to the throw of the cam or the
range of action to be given to the tool or die, and to this piece of metal or
moveable regulator a small handle is attached for the convenience of the
workman; the use of this will be hereafter referred to. I allow sufficient
room for the cam which actuates the punch, shear, or die (as they may be
respectively applied to such machine) to freely revolve after elevating the
púnch, die, or shear, and which will remain in that position until the atten-
dant has placed the work in position and desires to call into action either the
punch, shear, or die, according to the work or operation he may wish the
machine to perform, which he does by sliding in beneath the cam which has
a metal ring placed on it to admit of a smoother action in contact, the move-
able bed or piece of metal before referred to, and as the cam with the ring on
it-passes over its surface it depresses this adjustable piece of metal and carries
------

page_text: with it the bolt and tool and performs the operation desired, and, as the cam
continues to revolve, so the reverse motion will take place by its again lifting
up the bolt with the tool, where it will remain stationary at the will of the
operator while the machine continues to work by the attendant pulling the
piece of metal or moveable bed forward to allow the cam with the ring to
freely revolve within the space formed in the bolster or bolt, and when the
workman has again placed his work in position either for punching, shearing,
or pressing, according to the tool or tools that may be fixed in the machine,
he has only to place the moveable bed under the cam to effect this object.
These improvements, though simple, are of great benefit and use for many
descriptions of work on which such machinery is used, and may be constructed
to work upwards or downwards, that is, in each or both directions if required,
and may be set up vertically or horizontally or in any angular direction.
But in order to be better understood as to the extent of my Invention I will
proceed to describe the Drawings hereunto annexed, reference being made to
the Figures and letters marked thereon.
Fig. 1 represents a side elevation of an ordinary punching and shearing
machine, with my improvements applied to it. The gearing and fly wheel,
fast and loose pulleys, stand, and general form being similar to the apparatus
now commonly in use, and will need no description as its general construction
is explicitly shown and well understood by workmen accustomed to such
appliances, and Fig. 2 is a front view of Figure 1.
I will confine my description to the parts which form addition and novelty
in connection with such machines.
a is a circular eccentric pin formed on the outer end of the shaft on which
the toothed wheel b is placed, and which shaft and pin is represented in a
front and side view partly broken off at Fig. 3, the shaft being marked d, and
the pin a, as at Figure 2. On the pin a I place the wheel or roller c, shown
in a separate front and side view at Fig. 4, also marked c, This eccentric
pin with its roller c works in the square opening marked e, e, e, e, formed in the
part f,f, which part I call the bolt or slide, and have exhibited it in a separate
front and side view at Fig. 5, and in a top view at Fig. 6, which exhibit its
bevilled side 9, 9, as also the projection or table part h, which has projecting
sides and contracted front as at i, i, Figure 6, for the purpose herein-after stated.
To this bolt or slide the punch, shear, or other tool or appliances is applied
centrally from its lower end as shown at Figure 5, marked j, and which punch
or tool I prefer holding in by a small taper bolt as exhibited principally in
dotted lines in the side view Figure 5, and held in position against the side of
the tool so as to securely hold it by the nut k. The part F, F, is adjusted

page_text: centrally in position by the two parts m, m, which are held in by the squaro-
headed bolts as exhibited at Figure 2, and in a top view at Figure 7. By this
means a steady vertical action is permitted to the part F, and effected upward
by the periphery of the wheel c on the eccentric pin a, pressing against the
top side of the square opening e, e, as shown in Figure 2; and so well does this
part F fit that when elevated it will remain there, and not fall by its own
gravitation; by this it will be seen that the eccentric pin' and roller would
.continue to work around while the bolt or slide with the punch or tool will
be quiescent or stationary at the will of the workman, who affects the deprès-
sion of the tool as exhibited in Figure 2 by placing under the roller c when at
its highest throw the moveable bed marked L, so that as the roller: on 'the
eccentric pin passes around it, depresses the punch, shear, or die to the
extent of the eccentricity of the pin a, or the thickness of the moveable bed L.
This moveable bed. I have exhibited in a top and edge view at Fig. 8, the
part n being simply a bent hook by which the workman actuates it; and this
same part I have represented as it were drawn-out from under the action of
the roller and and resting on the table part marked h-in Figure 6, it being
prevented from being pulled too far out by the stops or ears formed on the same
for that purpose marked i, i, and as the punch or tool is represented at its
lowest range in Figures 1 and 2 by means of the moveable bed marked Ļ
partly shown in dotted lines at Figure 1 being placed in under the roller c, so
it will be seen that as the eccentric pin passes around, so the punch or tool
will be lifted; and when lifted by the elevation of the bolt or slide F the part
L has only to be pulled out at the pleasure of the workman, when the shaft
with its fly wheel may continue to revolve without imparting any action to
the punch until the workman has again adjusted his work and is prepared to
call into action the desired tool. O is simply a bed held in position by set screws
in the ordinary way marked p, p, passing through ears cast or formed with
the general stand. q is the die into which the punch pases, taking before it
the metal it has removed in punching the hole through the work under opera-
tion, while the part is simply a guage, being a piece of iron bent at right
angles and extends back and held on each side of the standard by set screws
that it may be advanced or retired as required. And the part S is a forked
lever also secured to the stand of the machine permitting the punch to work
down between the front forked part marked t, t, simply to release the work
from the punch when it is lifted up by the revolution of the eccentric, which
eccentric with the working parts may be covered over with a front plate
without interfering with the working of the machine; and this front plate I
have represented in place at Figure 1, marked U, but removed from Figure 2,

page_text: though its position is indicated by dotted lines, but which I have exhibited
detached at Fig. 9, the holes v, v, 'corresponding with the holes marked with
'the same letter in Figure 2.
Having thus fully described my improvements, and the manner in which the
same may be carried into effect, whether in the construction of a new machine
or applying them to the machines as now in use, I wish it understood that I
do not purpose limiting myself to the exact details herein described and
'exhibited as the part F may be arranged to work in grooves or slides, or other-
-wise constructed, or the moveable bed L, shown separately at Figure 8, may be
removed altogether from the machine and applied when required, but what I
claim as new and of my Invention and wish protected by these my in part
recited Letters Patent is, the use of the adjustable bed L or its equivalent to
súch machines, as well as the arrangement for giving effect to the same, by
which means the punch, shear, or other tool may be at rest while the fly
wheel, gearing, &c.; may be at work.

In witness whereof, I, the said William Bayliss, have hereunto set my
hand and seal, this First day of May, in the year of our Lord One
thousand eight hundred and sixty-five.
