page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, FREDERICK
WOODBRIDGE, of Old Gravel Lane, in the County of Middlesex, Engineer, send
greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Royal Letters Patent under the Great Seal of the United Kingdom of Great
Britain and Ireland, bearing date at Westminster, the Fifth day of September,
One thousand eight hundred and fifty, in the fourteenth year of Her reign,.
did, for Herself, Her heirs and successors, give and grant unto me, the said
Frederick Woodbridge, my exors, admors, and assigns, Her especial licence,
full power, sole privilege, and authority, that I, the said Frederick Wood-
bridge, my exors, adñiors, and assigns, or such others as I, the said Frederick
Woodbridge, my exors, adñors, or assigns, should at any time agree with, and
no others, from time to time and at all times during the term of years therein.
expressed, should and lawfully might make, use, exercise, and vend, within.
England, Wales, and the Town of Berwick-upon-Tweed, my Invention of
"IMPROVEMENTS IN MACHINERY FOR MANUFACTURING RIVETS, BOLTS, AND SCREW:
BLANKS;" in which said Letters Patent there is contained a proviso that. I, the
said Frederick Woodbridge, shall cause a particular description of the nature
of my said Invention, and in what manner the same is to be performed, by an
instrument in writing under my hand and seal, to be inrolled in Her Majesty's
Hight Court of Chancery within six calendar months next. and immediately
after the date of the said in part recited Letters Patent, as in and by the
same, reference being thereunto had, will more fully and at large appear..

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
Frederick Woodbridge, do hereby declare that the nature of my said Inven-
tion, and the manner in which the same is to be performed, are fully described
and ascertained in and by the following statement thereof, reference being
had to the Drawing hereunto annexed, and to the figures and letters marked
thereon, that is to say:-
My Invention consists of a mode of combining mechanical parts into a
machine for manufacturing. rivets, bolts, and screw blanks.
And in order that my Invention may be most fully understood and readily
carried into effect, I will proceed to describe the means pursued by me.
DESCRIPTION OF THE DRAWING.
Figure 1 is a plan of the machine; Figure 2 is a side elevation; Figure 3,
an end view, partly, in section; and Figure 4 is a transverse section of the
machine constructed and combined according to my Invention. a is a shaft
which receives motion from a steam engine or other power, and by means of the
pinion gives motion to the cog wheel c fixed on the axis d, on which is fixed
the mitre wheel e, which takes into and drives the mitre wheelf on the axis I,
on which is fixed the pinion h, which takes into the teeth of the wheel i, which
is fixed on the axis j, and on that axisj is also fixed the dise k, which through its
face carries a series of dies for cutting off and receiving a series of blanks to have
heads formed thereto by means of suitable headers or dies carried by the wheel i,
and the wheel i, and disc k carrying their respective dies, revolve in a trough
of water, so that each die after being used in making a rivit, or bolt, or screw
blank, will be immersed in water before being again used. The dies k¹ carried
by the disc consist of tempered steel or chilled cast iron, and they are fixed
in or through the face of the disc k, and there is a heading die i for each die
, and such heading dies are carried by and slide freely through the wheel i
and the pairs of dies , k, come into and. go out of action in regular succession
as hereafter described. is a friction band on the face of the teeth of the wheel
į, such friction band is to prevent the wheel-i moving, except when driven at
intervals by the pinion h, which has only three teeth thereon, as shown, but
other means of giving motion to the parts may be resorted to. The disc is.
retained correctly in position by means of a lever catch with a wedge formed
tooth, which enters in succession into the angular notches on the periphery of
the disc k, and it is caused to do so by the cam m on the axisg lifting the other
end of the lever at proper intervals. In order to feed the dies k¹, a rod of iron
or other metal, according to the nature of the article to be made, which is well
understood, is to be introduced between the rollers n, n, which are geared

page_text: together, and they receive motion by the connecting rod n¹ from the crank pin
n² on the axis d, the other end of the connecting rod being attached to a crank
23 moving freely on the axis, and carries a pall or driver n', which takes into
and drives the ratchet wheel n³, fixed on the axis of the lower roller n, by
which the rollers n, n, will at intervals be moved, so as to force a portion of
the rod into the die k', which may for the time being be in position to receive
the same.
o is a plate with a groove in it, against which the rod of metal
rests, and it forms a cutter against which the rod is pressed by the die k¹ in its
movement after receiving the end of the rod, and it is by this means, that is,
by a dick and the plate o, that the length is cut off to form a rivet, bolt, or
screw blank, according as the dies i, e, are suitable for one or other of those
articles.
The piece of metal thus cut off is carried forward by the rotation of the disc
till the next die k comes into position to be fed, and then the heading die
¹of the die k¹, which has been fed, will be brought into action, and be pushed
forward by means of the bolt p which slides in suitable bearings as shown, the
bolt p being actuated by means of the excentric p¹ on the axis d, and im-
mediately after a heading die has so been forced up it comes into position
for the finger 9 to move it back, the finger 7 taking hold of the projection on
the back end of the heading die . The finger q is carried by the sliding bolt
q', which slides in suitable bearings, as is shewn, and the bolt q' receives motion
by the connecting rod 2 connected to it and to a crank pin on the axis q³,
which axis receives motion from the axis d by means of the cog wheels q', q',
as shown. The bolt q' gives motion by the fingers q to the clearing punch 2
which slides in suitable bearings, and this punch clears the dies ¹, by forcing
out the articles which have been headed therein, and those articles fall down
the fixed inclined plane q. The heading dies are again brought into position
by means of the fixed inclined plane ».
Having thus described the nature of my Invention, and the manner in which
the same is to be performed, I would have it understood, that I do not confine
myself to the precise details as herein shown and described, as the same may
be varied, so long as the peculiar character of my Invention be retained, and I
make no claim to any of the mechanical parts separately; but what I claim is,
the mode herein described of combining mechanical parts into a machine
for making rivets, bolts, and screw blanks.
In witness whereof, I, the said Frederick Woodbridge have hereunto set
my hand and seal this twenty-seventh day of February, in the year of
our Lord One thousand eight hundred and fifty-one.
FREDERICK (L.S.) WOODBRIDGE.
