Improvements in Apparatus for Dispensing with Check Straps of
Shuttle Boxes of Looms for Weaving.
We JOSEPH ROBERT KEMP, Cotton Manufacturer, l'rospect Mill, Great Harwood
in the County of Lancaster, PETER HOUGHTON Mechanic and JOSEPH LEACH
Manager, both of Prospect Mill aforesaid, do hereby declare the nature of this
invention to be as follows:-
This invention relates to apparatus for breaking the impact of the shuttle's tip on
the picker when the shuttle enters the box, the object being to effect the desired
result without the aid of check straps heretofore commonly employed, the invention
consists of improved appliances in combination with the "swell" which retards the
shuttle on its entry to the box, the shuttlo being free from obstruction on the return
or outward pick.
According to this our invention we employ a blade spring one end of which is
attached to the crank arm for working the slay. The spring extends from the crank
arm to the back of the shuttle box and is bent or inclined at its free end so as-to
form a pad which will bear upon and against the part of the "swell" protruding
through the back of the shuttle box. The length and adjustment of the spring as
between the crank arm and shuttle box "swell" is such that one part of the move-
ment of the crank will bring the free end of the spring upon and against the back of
the "swell" the other part of the movement of the crank will carry back and remove
the spring clear of and out of contact with the back of the "swell." The contact
between the spring and the back of the swell is at the time when the shuttle is due to
enter the box, the swell" thus retards and eases the entrance of the shuttle to the
box and when the spring is removed from contact with the "swell" leaving the latter
entirely loose is at the time when the picker is due to propel or pick the shuttle out of
the box. There is of course a like spring applied to each of the shuttle boxes.

We, JOSEPH ROBERT KEMP, Cotton Manufacturer, Prospect Mill, Great Harwood
in the County of Lancaster, PETER HOUGHTON Mechanic and JOSEPH LEACH Manager,
both of Prospect Mill aforesaid, 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 apparatus for breaking the impact of the shuttle tip on
the picker when the shuttle enters the box the object being to effect the desired result
without the aid of check straps heretofore commonly employed, the Invention
consists of improved appliances in combination with the "swell" which retards the
shuttle on its entry to the box, the shuttle being free from obstruction on the return or
outward pick.
According to this our invention we employ a blade spring one end of which is
attached to the crank arm for working the slay. The spring extends from the crank
arm to the back of the shuttle box and is bent or inclined at its free end so as to form
a pad which will bear upon and against the part of the "swell" protruding through
the back of the shuttle box.
The length and adjustment of the spring as between the crank arm and shuttle box
"swell" is such that one part of the movement of the crank will bring the free end
of the spring upon and against the back of the "swell." the other part of the move-
ment of the crank will carry back and remove the spring clear of and out of contact
with the back of the "swell."
The contact between the spring and the back of the "swell" is at the time when
the shuttle is due to enter the box, the "swell" thus retards and eases the entrance
of the shuttle to the box and when the spring is removed from contact with the swell
leaving the latter entirely loose is at the time when the picker is due to propel or pick
the shuttle out of the box.
There is of course a like spring applied to each of the shuttle boxes, and the blade
spring is in some cases fixed to the swell and operated from the crank arm as
described.
:-
Such being the nature and object of this our said Invention, the following is a
coinplete description of same reference heing had to the accompanying drawings:-
Fig. 1 is a plan view of our improved apparatus for checking the shuttle on its
entrance to the box the blade spring being fixed to the crank arm.
Fig. 2. is an end elevation of same partly in section.
Fig. 3. is a similar view to fig. 1 but shewing the blade spring fixed to the swell of
the shuttle box.
Fig. 4 is an end elevation.partly in section of fig. 3..
According to this our Invention we employ a blade spring 1 attached by bracket 2
and bolts to the crank arm 3 which works the slay, the blade spring 1 is bent and

page_text: extends to and (when the slay is at the "beat up ") bears against the end 4 of the swell 5
the latter being hinged at its other end 6. The length and adjustment of the spring 1
as between the crank arm 3. and the end 4 of the swell 5 of the shuttle box 7 is such
that at the time the shuttle 8 is entering the box 7 and the slay almost at the
"beat up" the spring 1 is pressing against the end 4 of the swell 5 and the
shuttle 8 coming in contact therewith its impact is reduced, the spring 1 acting as
a buffer, and the shuttle 8 is held firmly in the box 7 until such time as the slay
and crank arm 3 make the return movement which removes the spring 1 from contact
with the swell 5 and thus there is no obstruction or pressure on the shuttle 8'
when the "pick" is made.
'
When the blade spring forms a portion of or is attached to the swell 5 (see
figs. 3 and 4) the pressure is applied to the blade spring by means of a finger 9
attached to the crank arm 3 the action of which and the mode of operating is
similar to that described above. There is of course a like spring and appliances
connected therewith at each end of the loom.
Having now particularly described and ascertained the nature of this our said Inven-
tion, and in what manner the same is to be performed we declare that what we
claim is :-
The spring 1 operated from the crank arm 3 controlling or forming the swell 5 all
in combination and for purpose described and as illustrated by drawings annexed.
