An Improvement in the Manufacture of Steel Bolts, Nuts, and
other Articles Usually Made by Forging..
I, THOMAS ROWE WESTON 131 St. Thomas Road Finsbury Park London N. Iron
Merchant do hereby declare the nature of this invention to be as follows:-
The object of this invention is to supercede the necessity of manufacturing steel
forgings and the like, from cast steel bars, strips or sheets and my invention has
relation to all description of screws bolts nuts pins spikes rivets washers (plain or
spring) fishplates and all fittings hitherto manufactured out of or from bars, strips or
sheets of steel or iron. My invention is carried into effect in the following manner.
I mould the pattern of the screw, washer, bolt, and so forth I wish to make in suitable
moulds for casting and I then run or pour the molten steel into the moulds thus
formed after the usual manner or mode of casting steel, thus doing away with the
necessity of first making the cast steel bars, strips or sheets and then forming the
articles named out of them, by means of forging shaping stamping heading piercing
and such like tools or machines. In some cases I mould the pattern of a screwed bolt
or wood screw and thus obtain the screw thread cast upon the bolt or screw at the
time of casting, thereby doing away with the necessity of screwing the bolt or screw
by a subsequent process.

1 THOMAS ROWE WESTON of 131 St. Thomas Road Finsbury Park N. in the
County of Middlesex Iron Merchant do hereby declare the nature of this invention
and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :-
The object of this invention is to supercede the necessity of manufacturing steel
forgings and the like from cast steel bars rods strips wire sheets portions or pieces
and my invention has relation to all description of screws bolts nuts pins spikes rivets
washers (plain and spring shape) fish plates and every and all description of fittings
or the like hitherto manufactured out of or from bars rods strips wire sheets pieces or
portions of steel or iron. My invention is carried into effect in the following
manner I mould or form the pattern of the screw washer bolt nut and so forth I
wish or desire to make in suitable moulds for casting and I then run pour or cause the
molten steel or similar metal to enter the moulds or substitute for moulds thus formed
after the manner or mode of casting steel or other similar metal thus doing away
with the necessity of first making the cast steel into bars and so forth and then
forming or making the various articles hereinbefore described out of them by means
of forging shaping stamping heading piercing slotting screw cutting and such like
machines or tools. Sometimes I use cores for casting made of cast iron or other
brittle substance which cores may be removed by striking them with a hammer or in
any other way. In some cases I mould the pattern of a screwed bolt wood screw screw-
nail nail-screw or tapped nut and thus obtain the screw-thread cast upon or in the bolt
screw or nut at the time of casting thereby doing away with the necessity of screwing
the bolt or wood screw or tapping the nut by a subsequent process. And in order
that my invention may be thoroughly understood I now proceed to describe the
accompanying drawings to show the different and various articles which are produced
thereby reference being had to figures marked thereon Figure 1 represents a
square headed coach screw Figure 2 is a half round headed wood screw Figure 3
is an hexagon headed bolt blank Figure 4 is an hexagon nut and a fang nut
Figure 5 represents a half round headed pin Figure 6 is a spike nail Figure 7 is a
rivet Figure 8. a plain round washer Figure 9 a spring wedge washer Figure 10
a spring washer Figure 11 a fishplate Figure 12 a wire fence fastener or wire
connector Figure 13 a staple.
Having now fully described the nature and object of my invention and the
manner in which the same is to be performed I claim as new and novel the
following:-
First. The process of casting any of the aforesaid articles in steel or similar metal
by their pattern being formed in moulds or substitutes for moulds and running or

page_text: pouring the molten steel or similar metal into the said moulds to form such like
articles as are herein substantially described and according to the accompanying
drawings.
Second. I claim to make any such like articles as can be cast or formed in a mould
or substitute for a mould of steel or similar metal any pattern shape form or size or
for any purpose substantially as herein described.
Third. I claim cores for casting purposes (whether for steel or any other metal or
substance) made of cast iron or any other brittle substance substantially as herein
described.
Fourth. I claim the casting in steel or similar metal the screw thread upon round
about in or inside a bolt screw screw-nail or nut substantially as herein described.
Fifth. I claim particularly the casting in steel or other metal the spring washers
figures 9 and 10 or any modification of them substantially as described and according
to the accompanying drawings.
Sixth. I claim particularly the spring wedge washer figure 9 or any modification of
it substantially as described and according to the accompanying drawings.
Seventh. I claim particularly the wire fastener or connector figure 12 or any
modification of it substantially as described and according to the accompanying
drawings.
Eighth. I claim particularly the forming by casting the slit slot or groove in the
head of a wood screw screw-nail or nail-screw according to figure 2 and substantially
as described.
