IMPROVEMENTS IN MACHINES FOR FORGING BOLTS, SCREWS, AND RIVETS
Year: 1884

page_text: I, JOSEPH PICKLES BINNS of 21 Wolseley Terrace, Halifax Yorkshire, Engineer
do hereby declare the nature of my invention for "IMPROVEMENTS IN MACHINES
FOR FORGING BOLTS, SCREWS, AND RIVETS" to be as follows:-
-
My invention has reference to that class of machine known by the name of
"Horsfall's" and for which Letters Patent were granted on the 5th day of October
A.D. 1869 N° 2882.
The first part of my improvements in such machines consist in providing means
to prevent the breakage of some of the parts when they get locked fast, or when
the cams have some unusual resistance to contend against.
In carrying out this part of my invention I employ a rocking shaft having two.
or more projecting arms, at the end of which are bearings in which the cam shaft
revolves. Behind each of the said projecting arms is placed a piece of hollow metal
which is held firmly together against the back part of the framework, so that the
unnecessary resistance which the cams sometimes meet with may cause sufficient
pressure against the said hollow pieces as to break them, and thereby prevent
further resistance and breakage of the machine.
The cam shaft is driven by a spur wheel placed thereon and gearing with
another spur wheel connected to a clutch box which revolves with the driving
wheel, when connected by clutch pin on a stationary shaft.
The second part of my improvements consist partly in re-arranging the position
of the tools, so that the bottom heading tool cannot come into contact with the side
hammers, nor can the side hammers come into contact with the bottom heading tool ;
I accomplish this by placing the said bottom heading tool in the slide at a position
above the said side hammers. The gripping dies are made with three holes, or
gripping places in them, instead of two as at present, the additional hole being for
the purpose of holding the hot iron, and when making square necked bolts the neck
can be left a little larger so that it can be better finished in the bottom hole, and
the said bottom heading tool can operate upon the hot iron independently and
separately from the said side hammers.
The third part of my improvements refer to that class of machine where side
hammers are not used, and my improvements therein consist in the employment of
ID 11

page_text: gripping dies provided with three separate holes or gripping places, the bottom
hole or gripping place being employed for holding the forged bolts, or rivets whilst
they are being cut off to the required length by a cutter occupying the position
where one of the side hammers would be if in use.
By employing the additional bole in gripping dies with the cutter as herein
mentioned, it is now unnecessary for the workman to move from his position to cut
the bolt off as is the case at present.
The adjustable gauge for determining the length of bolts, or rivets I now place
below the heading slide, the position of which is arranged to be clear of the gauge.
Dated this third day of September 1884.

page_text: I, JOSEPH PICKLES BINNS, of 21 Wolseley Terrace, Halifax, Yorkshire, Engineer,
do hereby declare the nature of my invention for "IMPROVEMENTS IN MACHINES
FOR FORGING BOLTS, SCREWS, AND RIVITS" and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
My invention has reference to that class of machine known by the name of
"Horsfall's" and for which Letters Patent were granted on the 5th day of October
A.D. 1869 N° 2882.
The first part of my improvements in such machines consist in providing means
to prevent the breakage of some of the parts when they get locked fast or when
the cams have some unusual resistance to contend against.
In order that my invention may be better understood I herein give reference to
the accompanying sheet of drawings wherein Fig 1 is end elevation, and Fig 2 plan
view of an ordinary "Horsfall's" bolt forging machine having my improvements
applied thereto.
A is the framing of machine, which according to my invention is formed with a
back part B for purposes hereinafter explained.
C is a casting capable of rocking upon bosses D supported at each end of the
machine, such rocking casting having arms E provided with pedestals F for
carrying the cam shaft G, upon which are placed the ordinary cams H for operating
the forging tools I. The casting C is prevented from moving forward by the lug
or projection K formed at the bottom thereof and which abuts against the part L
projecting from the framework, and between the framework B and the casting C
I place one or more bollow castings J which are held in position and adjusted by
screw and band wheel M which hollow castings are sufficiently strong as to keep
the cam shaft perfectly steady during the ordinary operations of the machine, but
should any of the parts get locked fast and some unusual strain be placed upon
the cams which sometimes happens, then in such case the casting C carrying
the cam shaft G would be forced against the hollow casting with such additional
force and power as to break it, the effect of which would be to allow the
casting C to oscillate or move backward, thereby preventing any further damage
to the machine.
The second part of my improvements consist partly in re-arranging the position
of the tools, so that the bottom heading tool cannot come into contact with the side
hammers, nor can the side hammers come into contact with the bottom heading
tool, I accomplish this by placing the said bottom heading tool in the slide at a
position above the said side hammers.
The gripping dies are made with three holes, or gripping places in them, instead
of two as at present, the additional hole being for the purpose of holding the hot
iron, and when making square necked bolts the neck can be left a little larger so
that it can be better finished in the bottom hole, and the said bottom heading tool
can operate upon the hot iron independently, and separately from the said side
hammers.

page_text: The third part of my improvements refer to that class of machine where side
hammers are not used, and my improvements therein consist in the employment of
gripping dies provided with three separate holes or gripping places, the bottom
hole or gripping place being employed for holding the forged bolts, or rivets whilst
they are being cut off to the required length by a cutter occupying the position
where one of the side hammers would be if in use,
By employing the additional hole in gripping dies with the cutter as herein
mentioned, it is now unnecessary for the workman to move from his position to cut
the bolt off as is the case at present.
The adjustable gauge for determining the length of bolts, or rivets I now place
below the heading slide, the position of which is arranged to be clear of the gauge.
The second and third parts of my invention are not illustrated by drawings as
the nature of them are such as will be easily understood by persons acquainted
with this class of machinery.
C
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
0
Firstly. In a bolt forging machine the employment of apparatus substantially as
herein shewn and described for carrying the cam shaft G whereby the said shaft
can oscillate or move back ward so as to prevent breakage of the machine when any
of the parts lock or become immoveable.
Secondly. The employment of the bottom heading tool so placed, and arranged
as to operate separately and independently of the hammers as herein set forth in
the second part of this specification.
Thirdly. The employment of gripping dies having three separate holes for
purposes set forth in the third part of this specification.
