PROVISIONAL SPECIFICATION left by the said William Robert Lake at
the Office of the Commissioners of Patents, with his Petition, on the
6th March 1866.
I, WILLIAM ROBERT LAKE, of the "International Patent Office," No. 8,
Southampton Buildings, Chancery Lane, in the County of Middlesex, Con-
sulting Engineer, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN MACHINERY FOR MAKING BOLTS, RIVETS, SPIKES, AND OTHER
SIMILAR ARTICLES," a communication, to be as follows:-
The object of the said improvements is the construction of a machine
which by one revolution of its main shaft will form two articles either of the
same or of a different kind, that is to say, both ends of the machine may be

page_text: made simultaneously to produce bolts, rivets, or spikes, or one end may make
rivets while the other end is making bolts or spikes. The framing which
supports the shafts and other working parts of the machine is of cast iron,
and is of suitable strength to give the required solidity and steadiness to the
machine when at work. Each end of the said framing is formed with a long
boss which is accurately bored out to form a bearing for the spindle or axis
of a rotating disc. These two discs carry the dies in which the rivets and
other articles are formed. The discs are formed with teeth upon their
perimeters, by which they receive an intermittant rotary motion from slotted
rods provided with pins or studs which take hold upon the said teeth. These
rods are by preference operated by cranks fixed upon a shaft which extends
from end to end of the machine, and works in suitable bearings secured to
the framing. The number of teeth on the perimeter of each disc corresponds
with the number of dies carried thereby, and the throw of the crank is so
regulated that for each revolution of the crank shaft each disc is turned one
tooth forward on its axis. The crank shaft receives its motion by bevilled
pinions from the main shaft, upon which is fixed a spur wheel gearing into a
pinion on the driving shaft, motion being imparted to the said driving shaft
in any ordinary and convenient manner. The rods or bars of iron or other
metal from which the rivets, bolts, or other articles are manufactured are fed
through holes formed in blocks of hardened steel fixed in the ends of the
framing. These holes are so situated with regard to the rotary discs that
each die therein is in turn brought and stopped directly opposite the said
holes. When therefore the end of a bar or rod is introduced into one of these
holes it will pass freely therethrough and through the die then opposite till
it comes in contact with the end of a gauge screw arranged behind each disc
in a line with the said holes. These gauge screws work through brackets
attached to the framing, and by their adjustment the length of the rod
projecting through the dies is regulated. A die for forming the heads of the
rivets, bolts, or other articles is also provided to operate in connection with
each of the rotating discs. These heading dies are carried in the ends of
sliding rods which work through suitable bearings supported by the framing,
and are operated by an excentric fixed on the main shaft. These rods are
connected to a yoke or strap passing over the said excentric; each end of the
machine is also furnished with a punch or driver for pushing out the finished
rivets or other articles from the dies. These punches are supported and
guided in brackets attached to the framing, and are operated by arms or
levers fixed upon rocking shafts supported in bearings also attached to the
said framing at each end of the machine. The said rocking shafts receive

page_text: their vibratory motion from an excentric fixed on the main shaft, to which
they are connected by suitable rods. The rotating discs and the dies secured
therein are kept cool by passing through water or other cooling medium
contained in troughs secured to or formed on the framing under each disc.
The end of the bar or rod resting in the dies is sheared off by the action of
the rotating disc, and the cut off portion or blank resting therein is by the
same movement of the disc carried round opposite to the heading die. This
die is forced into contact with the end of the said blank and forms the head
thereon. In making articles with square, hexagonal, or similar shaped heads
it may be necessary to subject the blank to the action of two heading dies,
one of which is by preference fixed at one end of the machine and the other
at the opposite end. When the heads are formed another movement of the
rotating disc carries the rivets or other articles opposite the punch or driver,
which forces them out from the dies into a shoot, whence they are discharged
into any suitable, receptacles.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Robert Lake in the Great Seal Patent, Office on
the 6th September 1866.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
ROBERT LAKE, of the "International Patent Office," No. 8, Southampton
Buildings, Chancery Lane, in the County of Middlesex, Consulting Engineer,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Sixth day of March, in the year of our Lord
One thousand eight hundred and sixty-six, in the twenty-ninth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
mė, the said William Robert Lake, Her special licence that I, the said
William Robert Lake, my executors, administrators, and assigns, or such
others as I, the said William Robert Lake, 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 MAKING BOLTS, RIVETS, SPIKES,
AND OTHER SIMILAR ARTICLES," upon the condition (amongst others) that I; the
said William Robert Lake, my executors or administrators, by an instrument

page_text: 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 William Robert Lake, do hereby
declare the nature of my said Invention, and in what manner the same is
to be performed, to be particularly described and ascertained in and by the
following statement, reference being had to the accompanying Sheet of
Drawings forming part of this Specification.
The object of the said improvements is the construction of a machine
which by one revolution of its main shaft will form two articles either of the
same or of a different kind, that is to say, both ends of the machine may be
made simultaneously to produce bolts, rivets, or spikes, or one end of the
said machine may make rivets while the other end is making bolts or

page_text: driving shaft J, which also carries the fast and loose punes J and motion
being communicated to the said shaft by a belt passing over the pulley J¹, or
in any other suitable and convenient manner. The rods or bars of iron or
other metal from which the rivets, bolts, or other "articles are manufactured
are fed through holes g, by preference formed in blocks of hardened steel fixed
in the ends of the framing A. These holes are so situated with regard to the
rotating discs c that each of the dies b. therein is in turn brought and stopped
directly opposite the said holes. When therefore the end of a bar or rod is
introduced into one of the holes g it will pass freely through the said hole and
through the die 6, then opposite or in a line therewith, till it comes in contact
with the end of the gauge screw K arranged behind each disc C in a line
with the holes g. These gauge screws work through brackets L attached to
the framing A, and by the adjustment of the said screws the length of the
rod or bar projecting through the dies 6 to form the rivet or other article is
regulated.
A die M, for forming the heads of the rivets, bolts, or other articles, is
also provided and arranged to operate in connection with each of the rotating
discs C. These heading dies are carried in the ends of sliding rods M¹,
which work through suitable bearings h, supported by the framing A. The
said rods are operated by an excentric N fixed upon the main shaft G, and
are connected to a yoke or strap N₁ passing over the excentric N.
Each end of the machine is also furnished with a punch or driver o for
pushing out the finished rivets or other articles from the dies b. These
punches are supported and guided in brackets i attached to the framing A,
and are operated by arms or levers P fixed upon rocking shafts Q, the said
shafts being supported in the bearings j, also attached to the framing A at
each end of the machine. These rocking shafts receive their vibratory motion
from an excentric R fixed on the main shaft G, to which they are connected
by the rods R¹, as shewn in Figure 1.
The rotating discs C and the dies b secured therein ar kept cool by water
or other cooling medium, which is, by preference, contained in troughs k,
secured to or formed on the framing A directly under each of the discs C.
The end of the bar or rod from which the rivets or other articles are to be
manufactured being inserted through the hole g at either end of the machine
into one of the dies b, the portion of the bar resting in the said die is sheared
off by the action of the rotating disc turning on its axis B in the direction
of the arrow, Figure 3. The cut off portion or blank remains in the said die,
and is by the same movement of the disc C carried round opposite to the
heading die M. This die M is then forced into contact with the end of the

page_text: "blank," and forms the head thereon. In making articles with square,
hexagonal, or other shaped heads it may be necessary to subject the "blank"
to the action of, two heading dies, one of which is by preference arranged at
one end of the machine, and the other at the opposite end thereof. When
the heads are formed another movement of the rotary disc C carries the
rivets or other articles forward opposite the punch or driver O, which forces
them out from the dies 6 into a shoot or conductor, whence they are discharged
into any suitable receptacles.
Having thus fully described the said Invention as communicated to me by
my foreign correspondent, and shewn how the same may be conveniently and
advantageously carried into practice, I claim,―
First, the peculiar construction of the rotating discs C to enable each of
the dies 6 carried thereby to be in turn brought into the proper relative
position with the hole g, the heading tool M, and punch O, to act in
conjunction therewith, for the purposes and substantially in the manner set
forth.
Second, operating the discs C by the rods D and cranks E, for the purpose
and substantially in the manner set forth.
Third, the rods M¹ carrying the heading tools M, constructed and operated
substantially in the manner set forth.
Fourth, the punches or drivers O, constructed and operated for the
'purpose and substantially in the manner set forth.
the
Fifth, the employment of the troughs k in combination with the discs C, for
purpose and arranged substantially in the manner set forth.
Sixth, the dies b, heading tools M, punches O, and adjustable screw K,
combined, arranged, and operated for the various purposes and substantially
in the manner set forth.
In witness whereof, I, the said William Robert Lake, have hereunto
set my hand and seal, this Sixth day of September, in the year of our
Lord One thousand eight hundred and sixty-six.
WILLIAM ROBERT LAKE. (L.S.)
