IMPROVED SWELL USED IN SHUTTLE BOXES OF LOOMS FOR WEAVING
Year: 1885

page_text: JAMES GREGSON of the firm of Gregson and Monk of Vulcan Iron Works,
Preston in the county of Lancaster, Machinist and loom maker, do hereby declare
the nature of my invention for "IMPROVED SWELL USED IN SHUTTLE BOXES OF
LOOMS FOR WEAVING," to be as follows:-
My improvement consists in making a swell with a boss and pivot at one end,
so constructed that the large turned part of the boss, and the turned pivot at the
bottom of the same fits into a cup shaped bracket with a small slot cut in at the
side, and by this means, the swell passes down the slot, and brings the pivot and
the large boss of the swell to fit within the circular holes of the cup shaped
bracket, the large hole in the cup being much larger than the slot allows the small
pivot and the large boss to fit within the cup, and the swell when turned into its
working position is further held by two projecting jaws which form part of the
outside boss of the cup shaped bracket, and gets hold of the straight part of the
swell, and is thus held more securely, and the said jaws bear a portion of
the weight of the swell, and will enable the pivot to last much longer, besides
the full depth of the boss of the swell is all bearing, by fitting in the full length of
the cup shaped bracket.
The cup shaped bracket is fastened behind the backboard by one bolt, and by
unscrewing the bolt the bracket and swell is removed at once, and nothing further
is required to be removed as the swell can be at once lifted out of the bracket.
In order that my Invention may be more fully understood and readily carried
into operation I will proceed to describe the accompanying Drawings, in different
views similar parts are marked with corresponding letters of reference.

The great advantage of this swell is, that it is so simple in construction, it can
be taken out or removed from the bracket instantly, and it is more securely
fastened, and being so strong and large in the boss, it will not be liable to wear
out so quickly, as the smaller pins do, and the simpleness of its construction will
allow the most inexperienced person to put the same to work.

JAMES GREGSON of the firm of Gregson and Monk, Vulcan Iron Works Preston
Machinist and loom maker in the county of Lancaster, do hereby declare the
nature of my invention for IMPROVEMENTS IN LOOMS FOR WEAVING and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
My improvement consists in making a swell with a boss and pivot at one end,
so constructed that the large turned part of the boss, and the turned pivot at the
bottom of the same fits into a cup shaped bracket with a small slot cut in at the
side, and by this means, the swell passes down the slot, and thus brings the pivot
and the large boss of the swell to fit in the circular holes of the cup shaped
bracket, the large hole in the cup being much larger than the slot allows the small
pivot and the large boss to fit into the cup, and the swell when turned into its
working position is further held by two projecting jaws, which form part of the
outside boss of the cup shaped brackets, and gets hold of the straight part of the
swell, and is thus held more securely, and the said jaws bear a proportion of
the weight of the swell and will enable the pivot to last much longer, besides the
full depth of the boss of the swell is all bearing by fitting in the full length of the
cup shaped bracket.
The cup shaped bracket is fastened behind the backboard by one bolt, and by
unscrewing the bolt, the bracket and swell is removed at once, and nothing further
is required to be removed as the swell can be at once lifted out of the bracket.
The swell bracket or cup shaped bracket can be made either fixed or regulating,
and by this means there can be more or less swell put against the shuttle, which is
in some cases a great improvement, especially in fast reed looms where the lift of
the swell must regulate the lift of the stop rod for passing over the frog and
preventing the loom from banging or knocking off. The great advantage of this
swell is that it is so simple in construction, it can be taken out or removed from
the bracket instantly, and it is more securely fastened, and being so strong and
large in the boss, it will not be liable to wear out so quickly, as the smaller pins
do, and the simpleness of its construction will allow the most inexperienced person
to put the same to work.
In order that my Invention may be more fully understood and readily carried
into operation, I will proceed to describe the accompanying drawings, in the
different views, similar parts are marked with corresponding letters of reference.
Fig. 1. represents the front view of the cup shaped bracket. A is the hole for
bolting the bracket to the backboard, C. 1. is the circular hole in the cup, D. 1. is
the circular hole in the bottom. E is the slot or opening in the side of the cup
shaped bracket, which allows the body of the swell to pass through to bring the
boss of the swell into its working position. F. are the two projecting jaws which
hold the swell more securely in its position, this bracket is used when a fixed or
stationery swell is required.
Fig. 2 & 3. are the top & front view of the swell. E. 1. Fig. 2. is the part of
the swell which passes through the slot or opening E of the cup shaped bracket,

page_text: C is the large boss of the swell, which works in the circular hole C. 1. D. is the
small pivot at the bottom of the swell which works in the circular hole D. 1.
Fig. 4. shows the swell placed in its working position in the cup shaped bracket,
the bracket is also a fixed bracket, and shows the swell securely fastened by the
projecting jaws F. at E. 1.
Fig. 5. shows the front view of the swell regulating bracket, complete and
ready for fixing to the backboard, this bracket is used when the swell requires
regulating.
Fig. 6. & 7. shows the swell regulating bracket seperate which shows plainly
how the means of regulation is got; by the face of one bracket sliding into the
face of the other, and being fastened by a bolt or set screw.
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 :-
The several parts combined to form a fixed or regulating swell constructed and
arranged as shown and described.
