Improvements in and connected with Collars and Couplings for
Shafting, Rods, and the like.
I, THOMAS GARE, of 25, Booth Street, Edgeley, Stockport, in the County of Chester,
Engineer, do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in and connected with collars and couplings
for shafting, rods and the like.
Heretofore such collars and couplings have been forged from wrought iron or steel
or cast of ordinary or malleable iron. When forged of wrought iron or steel they are
expensive and when made of cast or malleable iron they are liable to break and screw
threads cut into same soon wear.
The object of this invention is to provide collars and couplings for shafting, rods
and the like which can be produced much cheaper and are considerably stronger and
lighter than those hitherto used.
To this end I form such collars and couplings from metal bars of suitable section
preferably, taper, by coiling same closely together into cylindrical form.
Blanks are then cut from the said coil in lengths as may be required and after
having been heated, they are forced into a die having a stud conforin with the hole
of the blank. In forcing the said blank into the said die one by one, the coils of the
blank are compressed or welded together so as to form a solid body and the fibres
of the metal thus being placed spirally, a collar or coupling of great strength is
obtained.

Improvements in and connected with Collars and Couplings for
Shafting, Rods, and the like.
I, THOMAS GARE, of 25, Booth Street, Edgeley, Stockport, in the County of Chester,
Engineer, 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:-
This invention relates to improvements in and connected with collars and couplings
for shafting, rods and the like.
Heretofore such collars and couplings have been forged from wrought iron or steel
or cast of ordinary or malleable iron. When forged of wrought iron or steel they are
expensive and when made of cast or malleable iron they are liable to break and screw
threads cut into the same soon wear.

page_text: The object of this invention is to provide collars and couplings for shafting, rods
and the like which can be produced inuch cheaper and are considerably stronger and
lighter than those hitherto used as less substance of metal will give more strength.
"And in order that my invention may be more fully understood I have caused to be
appended hereunto one sheet of drawings marked with letters of reference indicating
like parts in the various figures.
Figs. 1 & 2 show coil blanks made of bars of different sections. Fig. 3 is a
longitudinal section, and Fig. 4 a plan of a die in which the said blanks are forged
and welded together.
In carrying out my invention I form my improved collars and couplings from metal
bars of suitable section preferably, taper, by coiling same closely together into
cylindrical form. Blanks a in the form as shown in Figs. 1 or 2, are then cut from
the said coil in lengths as may be required and after having been heated, they are
forced into a die, for instance such as shown in Figs. 3 & 4. In forcing the blank
into the die, the coils of the blank are compressed and welded together and become
one solid body and the fibres of the metal thus being placed spirally around its axis,
a collar or coupling is obtained of greater strength and less weight than hitherto.
The die I use may be formed with a base 6 having a central stud c adapted to be
withdrawn and sides in two parts d, d pivoted to the said base and held together by
means of a latch e whilst the ram or hammer f, whereby the coil blank a is compressed
in the die, may have a thrust or reciprocal action imparted by hand or motive power.
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 :-
Collars or couplings for shafting, rods and the like formed by coiling metal bars
into cylindrical form, placing blanks cut therefrom and heated into a die and
compressing and welding same therein to form one solid body, all substantially as
set forth.
