AN IMPROVED METHOD OF CONSTRUCTING CAGES FOR BOBBINS OR PIRNS
Year: 1884

page_text: JAMES GAMBLE No 201 Agnes Street Belfast Sheet Metal Worker do hereby
declare the nature of said invention for AN IMPROVED METHOD OF CONSTRUCTING
CAGES FOR BOBBINS OR PIRNS to be as follows:-
:-
This invention consists of a novel method of constructing cages or portable
creels for bobbins or pirns as used for carrying bobbins and pirns in spinning,
winding weaving &°.
The novelty consists in the form of the bottom to which the pins for carrying
the bobbins or piros are attached, and in the shape and method of making the pins.
The bottom of the cage is made of sheet iron or other suitable metal and on
this, bosses or projections are raised which have holes in their centres for the pins,
these projecting bosses stiffen the plate considerably and increase its strength or
rigidity.
The pins are made of wire on which a collar is raised by compression at a
suitable distance from one end this collar forming a shoulder for rivetting and
fixing the pins.
The collar on the pin is raised in the same manner as the head of a rivet by a
rivet making machine and the collar can be made of any required shape.
The collared pins can be used for cages with bar iron or other form of bottoms.

page_text: I JAMES GAMBLE 201 Agnes Street Belfast Sheet Metal Worker do hereby
declare the nature of my invention for AN IMPROVED METHOD OF CONSTRUCTING
CAGES FOR BOBBINS OR PIRNS and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement :-
This invention consists of a novel method of constructing cages or portable
creels for bobbins or pirns-as used for carrying bobbins and pirns in spinning
winding weaving &
The novelty consists in the form of the bottom to which the pins for carrying
the bobbins or pirns are attached and in the shape and method of making the pins.
This will be understood from the following description reference being had to the
drawing herewith in which the same letters and figures of reference always apply
to the same or like parts. Fig: 1 is a section of the cage bottom with pins in
Fig: 2 is a top view of same Fig: 3 is a section of a cage with pins in a
bottom formed of bars Fig: 4 is a top view of same Fig: 5 shews the shape of
pins used.
The bottom of the cage a is made of sheet iron or other suitable metal and on
this bosses or projections at are raised which have holes in their centres for the
pins 6 these projecting bosses a' stiffen the plato a considerably and increase its
strength or rigidity.
The pins are made of wire on which a collar b' is raised by compression at a
suitable distance from one end this collar b¹ forming a shoulder for rivetting and
fixing the pins b in the bottoms of the cages.
The collar b¹ on the pin b is raised in the same manner as the head of a rivet by
a rivet making machine and the collar b¹ can be made of any required shape.
The collared pins b can be used for cages with bar iron bottoms as shewn in
Figures 3 and 4 or flat metal bottoms as well as the sheet metal bottoms with
projecting bosses as illustrated in figures 1 and 2.
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 (1st) the making of bottoms for cages of sheet metal with bosses raised
thereon and (2nd) the shape of pins described with a collar raised thereon for the
purpose of rivetting against.
