Year: 1866

page_text: LETTERS PATENT to Moses Bayliss, of the Firm of Bayliss, Jones, and
Bayliss, of Wolverhampton, in the County of Stafford, Manufacturers,
for the Invention of "IMPROVEMENTS IN MACHINERY FOR THE MANUFACTURE
OF BOLTS AND SPIKES AND OTHER SIMILAR ARTICLES,"
Sealed the 28th December 1866, and dated the 21st July 1866.
PROVISIONAL SPECIFICATION left by the said Moses Bayliss at the Office
of the Commissioners of Patents, with his Petition, on the 21st July
1866.
I, MOSES BAYLISS, of the Firm of Bayliss, Jones, and Bayliss, of Wolver-
hampton in the County of Stafford, Manufacturers, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN MACHINERY FOR THE MANU-
FACTURE OF BOLTS AND SPIKES AND OTHER SIMILAR ARTICLES," to be as follows:-
My Invention consists of the arrangement or combination herein-after
explained of the parts of machinery for the heading of rods of iron for the
manufacture therefrom of bolts and spikes and other similar articles, such as
screw blanks and rivets, by which said arrangement or combination great
facility and economy of manufacture result.
In constructing machinery according to my Invention I fix in the slide or
bolt of the machine two dumping dies (that is, dies by which the upsetting

page_text: or shaping of the end of the rod is effected preparatory to the formation of the
head) and I also fix in the said slide or bolt a heading die, the said dumping
dies and heading die operating simultaneously upon three rods of iron brought
under them. The rods of iron to be headed are carried by a revolving hori-
zontal table to which an intermittent motion is communicated in any con-
venient way, boxes or beds in the table receiving the said rods. The rods to
be headed are supported in the boxes or beds described by means of sliding
pistons commonly called dummies or pimplers under the said boxes
These dummies or pimplers, and consequently the spikes or bolts, are raised
in the revolving table at the proper times by means of fixed inclines underneath
the said revolving table. The rod of iron to be headed is placed in one of the
boxes or beds of the revolving table and brought by the revolution of the said
table under the first dumping die and the upper heated end of the said rod
upset or shaped by the said dumping die and the lower die or box or bed in
which it is placed. By the further revolution of the table the partially headed
rod is brought under the second dumping die and further shaped by the said
second die, the rod at the same time being raised in the box or bed by the
action of the incline under the revolving table upon the dummy or pimpler
supporting the said rod. By the further revolution of the table the partially
headed rod is brought under the heading die and finally headed so as to con-
vert it into a bolt or spike or other similar article. After the heading has
been effected the headed bolt or spike is on the rotation of the table ejected
from the box or bed by means of a second incline under the table
acting upon the dummy or pimpler, although for convenience of description
I have only described the successive action of the two dumping dies and the
heading die upon one rod, yet in practice the dumping dies and heading die
operate simultaneously upon three rods carried by the revolving table, that is
at each fall of the slide or bolt of the machine one rod is headed and two rods
partially headed or upset. And although I have only described the use of two
dumping dies yet one dumping die or more than two dumping dies may be used
in conjunction with the heading die. The revolving table may contain two,
three, or more sets of boxes or beds so that one set may be conveniently filled
with heated rods while the rods in another set are being operated upon. The
essence of my Invention consists in combining or arranging the parts of the
machine so that one, two, or more dumping dies and a heading die are made
to operate simultaneously upon two or more rods so as thereby to head a bolt
or spike or other similar article at each stroke of the machine each of the rods
being carried in the same box or bed of the revolving table for the two, three,
or more operations as may be required. Also raising the bolts or other articles

in pursuance of the conditions of the Letters, Patent, filed
by the said Moses Bayliss in the Great Seal Patent Office on the 15th
January 1867.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, MOSES
BAYLISS, of the Firm of Bayliss, Jones, and Bayliss, of Wolverhampton, in the
County of Stafford, Manufacturers, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-first day of July, in the year of our Lord
One thousand eight hundred and sixty-six, in the thirtieth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
Moses Bayliss, Her special licence that I, the said Moses Bayliss, my
executors, administrators, and assigns, or such others as I, the said Moses
Bayliss, my executors, administrators, and assigns, should at any time agree
with, and no others, from time to time and at all times thereafter during the
term therein expressed, should and lawfully might make, use, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN MACHINERY FOR
THE MANUFACTURE OF BOLTS AND SPIKES AND OTHER SIMILAR ARTICLES," upon the
condition (amongst others) that I, the said Moses Bayliss, my executors or ad-
ministrators, by an instrument in writing under my, or their, or one of their
hands and seals, 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 Moses Bayliss, do hereby declare the
nature of the said Invention, and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement
thereof, that is to say:-
My Invention consists of the arrangement or combination herein-after
explained of the parts of machinery for the heading of rods of iron for the
manufacture therefrom of bolts and spikes and other similar articles, such as
screw blanks and rivets, by which said arrangement or combination great
facility and economy of manufacture result.
In constructing machinery according to my Invention I fix in the slide or

page_text: bolt of the machine two dumping dies (that is, dies by which the upsetting
or shaping of the end of the rod is effected preparatory to the formation of the
head) and I also fix in the said slide or bolt a heading die; the said dumping
dies and heading die operating simultaneously upon three rods of iron brought
under them. The rods of iron to be headed are carried by a revolving hori-
zontal table to which an intermittent motion is communicated in any con-
venient way, boxes or beds receiving the said rods. The rods to
be headed are supported in the boxes or beds described by means of sliding
pistons commonly called "dummies" or "pimplers" under the said boxes.
These dummies or pimplers, and consequently the spikes or bolts, are raised
in the revolving table at the proper times by means of fixed incline underneath
the said revolving table. The rod of iron to be headed is placed in one of the
boxes or beds of the revolving table and brought by the revolution of the said
table under the first dumping die and the upper heated end of the said rod
upset or shaped by the said dumping die and by the lower die or box or bed in
which it is placed. By the further revolution of the table the partially headed
rod is brought under the second dumping die and further shaped by the said
second die, the rod at the same time being raised in the box or bed by the
action of the incline under the revolving table upon the dummy or pimpler
supporting the said rod. By the further revolution of the table the partially
headed rod is brought under the heading die and further headed so as to con-
vert it into a bolt or spike or other similar article. After the heading has
been effected the headed bolt or spike is on the rotation of the table ejected
from the box or bed by means of a second incline or by a rod under the table
acting upon the dummy or pimpler. Although for convenience of description
I have only described the successive action of the two dumping dies and the
heading die upon one rod, yet in practice the dumping dies and heading die
operate simultaneously upon three rods carried by the revolving table, that is,
at each fall of the slide or bolt of the machine one rod is headed and two rods
partially headed or upset. And although I have only described the use of two
dumping dies yet one dumping die or more than two dumping dies may be used
in conjunction with the heading die. The revolving table may contain two,
three, or more sets of boxes or beds, so that one set may be conveniently filled
with heated rods while the rods in another set are being operated upon.
Having explained the nature of my Invention I will proceed to describe,
with reference to the accompanying Drawing, the manner in which the same
is to be performed.
Figure 1 represents in elevation a portion of a bolt heading machine.con-

page_text: taining my improvements; Figure 2 is a plan of the revolving table of the
same; Figure 3 is a vertical section of Figure 2 taken through the line x;
Figure 4 is a cross section of the slide or bolt of the machine and the dies
carried by it; Figure 5 is a plan and Figure 6 a side elevation of the platform
and fixed incline of the said machine. The same letters of reference indicate
the same parts in each Figure of the Drawing; a is the slide or bolt of the
machine working between the uprights b, b, and having motion given to it in
the ordinary manner. In the said slide or bolt a two dumping dies marked
c, d, and a heading or finishing die marked e are fixed, the said dies c, d, e,
rising and falling simultaneously; f is the revolving horizontal table working
on the bed g the said table having an intermittent rotary motion given to it
through the axis or shaft h by any convenient gearing. Fixed in a circle in
the table is a series of beds or dies i in which the heated rods to be headed
are placed and by which they are parily fashioned. The heated rods are sup-
ported in the beds or dies i by the sliding pistons k commonly called "dummies
or "pimplers" the said dummies being situated partly in the table f and being
supported on the fixed platform round which they are carried on the
revolution of the table f. The said table f is situated excentric to the bolt
or slide a so that on the rotation of the said table those portions of it con-
taining the dies i come in succession under the bolt a. The dies or beds i of
the table and the dies c, d, e, of the bolt a are arranged on a curved line of the
same radius, hence when the table f is brought to the rest the axes of three of
the said beds or dies i coincide with the axes of the dies c, d, e. The rods of
iron are lifted in the dies i at the proper times by the dummies or pimplers k
travelling up the incline 12 on to the raised part of the fixed platform 1.
After the headed rods have been ejected from the dies i the pimplers are
allowed to descend on to the platform I by means of the second incline 1. The
revolving table contains three sets of dies or beds i so that two sets may be
conveniently filled with heated rods while the rods in another set are being
operated upon.
The action of the machine is as follows:-The heated rods to be headed
having been fed into the beds or dies i, one of the said rods is brought by the
revolution of the table under the first dumping die c. The table coming
to rest the slide or bolt a descends, and the upper heated end of the said rod
is upset or shaped by the said dumping die and the bed or die i in which it is
placed. By the further revolution of the table the partly headed rod is lifted
in the bed i by the lower end of the dummey travelling up the incline to
the raised part of the platform 1, after which the same rod is successively
operated upon by the second dumping die d and heading or finishing die e, and

page_text: the said rod thereby headed and converted into a bolt, spike, or other similar
article. I have only described the action of the three dies c, d, e, upon one
rod, but the said three dies operate simultaneously upon three rods in the
table so that on each fall of the slide or bolt a of the machine one rod is com-
pletely headed and two rods partially headed or upset.
By an examination of Figure 1 of the Drawing it will be seen that the rod
m has been partially headed by the successive actions of the dumping dies c, d,
upon it, and that the rod n has been upset only by the action of the first dump-
ing die c upon it, the said rods m, n, having by the revolution of the table f
been brought under the heading or finishing die e and second dumping die d
respectively, and a fresh heated rod p also brought under the first dumping
die c. By the fall of the bolt or slide a the partially headed rod m is finished
or headed, the rod n is further upset and the rod p is partially upset as repre-
sented in Figure 3, which represents the rods m, n, p, after the dies e, d, c,
have respectively acted upon them. The finished or headed bolt or spike or
other similar article is ejected from the die or bed i in which it has been
partly fashioned by means of a rod rising through a slot q in the raised part-13
This rod for
of the platform and acting upon the dummey or pimpler k.
ejecting the bolt or spike is operated upon in the usual way and constitutes
no part of my Invention. Or the finished bolt or spike may be' ejected from
the die or bed i by means of an incline on the platform lover which the
dummey or pimpler on the rotation of the table travels. Instead of making
the incline of the platform fixed it may be made moveable as represented
in plan in Figure 7 and section in Figure 8 of the Drawing where the move-
able incline is marked 1. The incline is moved forward into its place at the
proper times to lift the rod to be operated upon by means of a wedge, the
return motion being effected by a spring. But the said moveable incline may
be worked in any other convenient manner. When required one
dumping die only or more than two dumping dies may be used in conjunction
with the heading die.
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 do not limit
myself to the precise details herein described and illustrated in the accom-
panying Drawing as the same may be varied without departing from the nature
of my Invention.
But I claim as my Invention the improvements in machinery for the manu-
facture of bolts, spikes, and other similar articles herein-before described and
illustrated in the accompanying Drawing, that is to say, arranging or combining
the parts of a machine for heading rods of iron substantially in the manner

page_text: described and illustrated, whereby one, two, or more dumping dies and a
heading die are made to operate simultaneously upon two or more heated rods
so as to head a bolt, spike, or other similar article at each stroke of the
machine, each of the rods being carried in the same box or die of a revolving
table for the two, three, or more operations as may be required. Also lifting
the rods at the proper time by means of an incline beneath the revolving
table.
In witness whereof, I, the said Moses Bayliss, have hereunto set my hand
and seal, this Tenth day of January, in the year of our Lord One
thousand eight hundred and sixty-seven.
Witness,
GEORGE SHAW.
