'IMPROVEMENTS IN PIPE COUPLINGS, NUTS FOR BOLTS, AND THE LIKE'
"
PROVISIONAL SPECIFICATION left by the said William Stainton at the
Office of the Commissioners of Patents on the 6th November 1880.
WILLIAM STAINTON, of 26, Liverpool Street, King's Cross, in the County of
Middlesex, Hot Water Engineer. "IMPROVEMENTS IN PIPE COUPLINGS, NUTS FOR
BOLTS, AND THE LIKE."
This Invention has for object to obviate the inconvenience and loss of time
which frequently arise from the slipping of the tongs or wrenches employed when
screwing up or tightening the sockets and back nuts in pipe-couplings, caps for the
ends of pipes, and to allow of pipe tongs or wrenches being used for screwing up
nuts for bolts.
My improvements consist in serrating, indenting, or channelling the outer
surfaces of the sockets, back nuts, screw caps for pipes, and nuts for bolts, such
serrations, indentations, or channels, running in the direction of the axis of the
socket, nut, or other article. Further, back nuts and nuts for bolts when manu-
factured according to my improvements are made round, instead of it being
necessary as at present to make them square, hexagonal, or other similar shape.
The indentations, serrations, or channels may be made or formed by any suitable
known means, such as by means of top and bottom tools, or by means of dies.
By forming the sockets, back nuts, caps and nuts for bolts, as hereinbefore
described, I am enabled to dispense with the use of spanners or keys for screwing
up or tightening the same, as the hereinbefore described serrations allow of simple
pipe tongs or wrenches being used for screwing up or tightening, the jaws of the
tongs or wrenches falling or taking into the said indentations, and allowing of the
best possible grip being obtained without requiring great exertion to prevent
slipping as at present; and further, in the case of back nuts and nuts for bolts,
from their being made round and serrated, as hereinbefore described, I am enabled
to turn them from any point to any point, which cannot in all cases be done when
an ordinary spanner has to be employed.

WILLIAM STAINTON, of 26, Liverpool Street, King's Cross, in the County of
Middlesex, Hot Water Engineer. "IMPROVEMENTS IN PIPE COUPLINGS, NUTS
FOR BOLTS, AND THE LIKE.'
This Invention has for object to obviate the inconvenience and loss of time
which frequently arise from the slipping of the tongs or wrenches employed when
screwing up or tightening the sockets and back nuts in pipe-couplings, caps for the
ends of pipes, and to allow of pipe tongs or wrenches being used for screwing up
nuts for bolts.
My improvements consist in serrating, indenting, or channelling the outer
surfaces of the sockets, back nuts, screw caps for pipes, and nuts for bolts, such
serrations, indentations, or channels running in the direction of the axis of the
socket, nut, or other article. Further, back nuts and nuts for bolts when
manufactured according to my improvements are made round, instead of it being
necessary as at present to make them square, hexagonal, or other similar shape.
The indentations, serrations, or channels may be made or formed by any suitable
known means, such as by means of top and bottom tools, or by means of dies or by
casting.
In the accompanying Drawing I have shewn as an illustration of my Invention
at Figures 1 and 2 respectively, a side elevation and a transverse section of a socket
for pipes manufactured according to my improvements, the socket being shewn as
connecting the ends of two pipes; A shews the socket formed with channels,
serrations, or indentations on its outer surface; B, B, the ends of the pipes.
By forming the sockets, back nuts, caps and nuts for bolts, as herein before
described, I am enabled to dispense with the use of spanners or keys for screwing
up or tightening the same, as the herein before described serrations allow of simple
pipe tongs or wrenches being used for screwing up or tightening, the jaws of the
tongs or wrenches falling or taking into the said indentations, and allowing of the
best possible grip being obtained without requiring great exertion to prevent
slipping as at present; and further, in the case of back nuts and nuts for bolts,
from their being made round and serrated, as herein before described, I am enabled
to turn them from any point to any point, which cannot in all cases be done when
an ordinary spanner has to be employed.
Having thus described my Invention, and the best means I am acquainted with
for carrying the same into effect, what I claim is,-
The manufacture and use of sockets, back nuts, screw caps for pipes, nuts for
bolts, and the like, having their outer surfaces serrated, indented, or channelled, as
and for the purpose herein before described.
In witness whereof, I, the said William Stainton, have hereto set my hand
and seal, this Twenty seventh day of April, in the year of our Lord One
thousand eight hundred and eighty one.
Witness,
G. F. REDFERN,
