ARTHUR WILLIAM LOVELL REDDIE of the Office for Patents 66 Chancery Lane
in the County of Middlesex, Patent Agent, IMPROVEMENTS IN THE MANUFACTURE
OF TURNBUCKLES AND ANALOGOUS SOCKETED ARTICLES. [communicated to him
from abroad by Edward White Merrill, a person residing at Brooklyn in the State
of New York, United States of America
This invention is particularly applicable to the manufacture of turnbuckles, but
is also applicable to the manufacture of socketed links or other articles comprising
a socket or sockets and parallel rods or bars extending therefrom.
The improvements consist in coiling the contiguous ends of two or more bars
or rods together at the point where it is desired to form a socket and in welding
and forging the coil so as to give it a tubular shape to form a socket.
4
The forging is preferably accomplished by placing the coiled or twisted portions
of the rods or bars heated to a welding heat in a divided die and subjecting the
die to the action of a drop press in a manner similar to that in which drop forgings
are made.
-
By the action of the dies the several convolutions of the coil are welded together
into one integral mass of tubular shape to form a socket in which is a smooth hole
of proper size to receive a bolt or rod used with the turnbuckle.
Although the invention is particularly applicable to turnbuckles it is also
applicable in forging any articles comprising two or more parallel rods or bars
connected by an integral socket; and by this invention the manufacture of turn-
buckes and analogous articles is cheapened, and a stronger and better article is
produced. It is obvious that rods, or bar iron of square or other form, may be
used to form the improved turnbuckles or socketed articles.

ARTHUR WILLIAM LOVELL REDDIE of the Office for Patents 66 Chancery Lane
in the County of Middlesex Patent Agent "IMPROVEMENTS IN THE MANUFACTURE
OF TURNBUCKLES AND ANALOGOUS SOCKETTED ARTICLES" a communication to me
from abroad by Edward White Merrill a person residing at Brooklyn' in the State
of New York, United States of America.
This Invention is particularly applicable to the manufacture of turnbuckles but
is also applicable to the manufacture of socketted links or other articles comprising
a socket or sockets and parallel rods or bars extending therefrom.
The improvements consist in coiling the contiguous ends of two or more bars
or rods together at the point where it is desired to form a socket, and in welding
and forging the coil so as to give it a tubular shape to form a socket.
The forging is preferably accomplished by placing the coiled or twisted portions
of the rods or bars heated to a welding heat in a divided die; 'and subjecting the.
die to the action of a drop press in a manner similar to that in which drop forgings
are made.
In the accompanying drawing Fig 1 represents a side view of two rods coiled
at a proper distance apart to form the sockets of a turnbuckle. Fig 2 represents
an end view thereof, Figs 3 represent an end view of a divided die whereby the
two parallel portions of the turnbuckle are held while the socket is partially
formed and a transverse section of the turnbuckle in one portion of said die, the
other portion being slightly removed therefrom, Fig 4 represents the plan view of
one portion of the die whereby the socket is formed, Fig 5 represents a side view
of the completed turnbuckle, and Fig 6 represents a section thereof on the dotted
line x x Fig 5
Similar letters of reference designate corresponding parts in all the Figures.
A. A designate two round rods or bars which are of proper size to form the two
sides or parallel portions of the turnbuckle-These rods or bars are coiled or twisted
together at each end so as to form two double coils or spirals A¹ which have a
central opening or hole a which is larger than the diameter of the hole in the
finished socket.
These coils A¹ may be forged into sockets by hand, but it is preferred to do it
by drop forging, and in Figures 3 and 4 are represented dies which are employed
for this purpose.
BB Figs 3 represent the two parts of a divided die which have cavities a¹ which
are adapted to receive the two rods A close to the coil A¹.,
A welding heat is first taken on the coil A and the die B B is fitted upon the
rods close to the coils, after which a blow is delivered upon the coil by a drop press
in the direction of the length of the turnbuckle to weld the convolutions of the
coil together―The finishing die is composed of two parts B¹ one of which is shewn
in Fig 4; in the adjacent faces of which is formed a cavity b of proper shape to
give form to the socket and also to receive the portions of the two rods A, which
are adjacent to the socket-In the adjacent faces of the two portions B B of the
die is also formed a hole into which a round mandrel C may be inserted; as seen
in Fig 4, to form the hole of: proper size in the finished socket.
After the coils A¹ have been formed in the rods A, and partially welded as above
described, the coils are heated and placed one at a time in the cavity b in the
adjacent faces of the two portions B₁ of the die, the mandrel C is inserted through
the hole or opening a in the coil, and the die is subjected to the action of a drop

page_text: press which forces the two portions of the die together and causes the coil A¹ to
completely fill the cavity b in the portions of the die.
The two portions of the die are then separated the mandrel C knocked out and
the other coil A¹ of the turnbuckle is subjected to the same operation.
By the action of the dies the several convolutions of the coil A¹ are welded
together into one integral mass of tubular shape to form a socket in which is a
smooth hole of proper size to receive a bolt or rod used with the turnbuckle.
In figures 5 and 6 which represent two views of the completed turnbuckle A*
designates the completed sockets, and a² the holes through the same.
Although the Invention is particularly applicable to turnbuckles, it is also
applicable in forging any articles comprising two or more parallel rods or bars
connecting by an integral socket, and by this Invention the manufacture of turn-
buckles and analogous articles is cheapened and a stronger and better article is
produced. It is obvious that rods or bar iron of square or other form may be used
to form the improved. turnbuckles or socketted articles, instead of round rods or
bars as represented in the drawing.
Having now described the nature of the said Invention of "Improvements in
the Manufacture of turnbuckles and analogous socketted articles" as communicated
to me by my Foreign Correspondent, and explained in what manner the same
may be carried into practical effect I wish it to be understood that I claim :-
The improvement in the art of manufacturing turnbuckles and analogous articles
herein described, which consists in coiling or twisting together the contiguous ends
of two rods or bars, and then welding and forging the coiled or twisted portions
into tubular shape to form sockets.
In witness whereof I the said Arthur William Lovell Reddie have hereunto
set my hand and seal the twenty second day of January in the year of our
Lord One thousand eight hundred and eighty four.
