· Improvements in Weft Fork Heads or Supports.
I JOHN CLEGG of Stone Bridge, Colne, in the County of Lancaster, Weft Fork
Maker, do hereby declare the nature of this invention to be as follows:-
My said invention relates to the heads or supports in which weft forks are
pivotted in the manner well known to those acquainted with the manufacture and
operation of looms for weaving. The said weft fork heads consist of a shank or
rod having at one end a jawed bracket or head in which the weft fork is pivotted
so as to swing freely. At present these heads are connected to the shank or rod
by being welded thereto, but this is an expensive mode of manufacture and the
parts are sometimes burned in welding. In other cases the head or bracket is cast.
in malleable iron with an eye to receive a squared and reduced extension of the rod.
the said squared extension being rivetted in and to the eye. This forms a weak
part in the rod and often results in breakage.
According to my invention I make the jawed bracket or head by stamping or
pressing it out of sheet steel or other suitable metal the stamped head being formed
with an eye suitable for receiving the rod or shank. The rod or shank is reduced
sufficiently to enter the eye of the improved stamped or pressed head, and to secure
the head firmly upon the rod I braze the head and rod together so as to unite them
strongly and securely. The stamped or pressed jawed heads are light and strong
and are so easily and cheaply made that the cost of the appliance is materially
diminished while the brazing of the head to the rod makes a very secure and
reliable joint.

Improvements in Weft Fork Heads or Supports.
I JOHN CLEGG of Stone Bridge, Colne, in the County of Lancaster, Weft Fork
Maker, 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 and accompanying drawings
My said invention relates to the holder heads or jawed supports in which weft
forks are pivotted in the manner well known to those acquainted with the manu-
facture and operation of looms for weaving.
The said weft fork holder heads
consist of a shank or rod having at one end a jawed bracket or head in which the
weft fork is pivotted so as to swing freely. At present these heads are connected
to the shank or rod by being welded thereto, but this is an expensive mode of
manufacture and the parts are sometimes burned in welding. In other cases the
holder head or bracket is cast in malleable iron with an eye to receive a squared
and reduced extension of the rod, the said squared extension being rivetted in and
to the eye. This forms a weak part in the rod and often results in breakage.

page_text: According to my invention I make the jawed bracket or head by stamping or
pressing it out of sheet steel or other suitable metal the stamped carrier bracket
being formed with an eye suitable for receiving the rod or shank. The rod or
shank is reduced sufficiently to enter the eye of the improved stamped or pressed
bracket, and to secure the same firmly upon the rod I braze the bracket and rod
together so as to unite them strongly and securely. The stamped or pressed jawed
brackets or heads are light and strong and are so easily and cheaply made that the
cost of the appliance is materially diminished, while the brazing of the bracket to
the rod makes a very secure and reliable joint.
Lest the foregoing description should not be sufficiently full and clear thoroughly
to elucidate my invention, I will now proceed to ascertain the same more particularly
and with reference to the annexed sheet of illustrative drawings.
Fig. 1. shows the flat piece of sheet steel from which my improved weft fork
carrier bracket is formed.
Fig. 2. shows the same piece after the first stamping operation.
Fig. 3. shows the same after the second stamping.
Fig. 4. is an end view of the finished carrier bracket mounted on and brazed to
the shank.
Fig. 5. is a view at right angles to Fig. 4.
Fig. 6. is a perspective view of the carrier bracket mounted on its shank.
I take the flat piece a of steel shown in Fig. 1 and first stamp or press it by any
suitable means into the shape shown at Fig. 2, the first stamping forming one lug a
of the carrier bracket and the eye a² which is to receive the shank. I then submit
the piece to a further stamping operation forming it as shown in Fig. 3 with the
other lug a³.
The jawed carrier bracket is now finished and I next fix it on the reduced end of
the shank b. This I do by brazing in the ordinary manner, the stamped bracket.
being thus firmly fixed upon the shank.
The lugs a¹ as of the bracket are now bored to receive the screwed stud c which
appears in Figs. 4, 5, and 6, and which passes through the boss of the weft fork as
is well understood, so that the weft fork is pivotted thereon and between the lugs
of the stamped or pressed carrier bracket. I thus secure a light and strong jawed
bracket head strongly and reliably connected to the shank b.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is:
:-
Forming the jawed carrier bracket or holder head in which the weft fork is
pivotted, by stamping or pressing the same from sheet steel or other metal and
brazing or securing the said stamped or pressed holder head firmnly to the shank,
substantially as described and shown.
