COMPLETE SPECIFICATION.
Improvement in the Construction of "Shuttle Picker Check Swell"
for Weaving Loom Revolving Shuttle Boxes.
WILLIAM HAIGH of 12 and 14, Otley Road Skipton Yorkshire, Smith and
Mechanic, ROBERT FRANCIS HAIGH of 34 Otley Street Skipton Yorkshire,..
Loom Overlooker, 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:-
(Par. 1.) This invention has for its object the construction of a "shuttle picker
check swell," for checking the rebound of shuttle picker in weaving loom revolving.
shuttle box.
(Par. 2.) We connect to the check swell-(Fig. 1A)-which projects into the
picker race (Fig. 1. JJJJ) a stem or spindle, at any angle as may be convenient.
for adaptation and attachment to the varying shaped manufacture of loom. And
for the purpose of this Specification is shewn in drawings at right angle. (Figs. 1
and 2, B B).
(Par. 3.) This stem or spindle is of square or of any other section which will
prevent oscillation in the socket or sockets (Figs. 1 & 2. C & C. C) perforated for
its reception.
(Par. 4.) (Figs. 1 & 2) shew two optional methods of actuating the combined stem.
or spindle and swell. The metal coil spring (F Fig. 1) or other elastic spring-
as for instance india rubber-is extended from the fixed arm (a, upon socket C
Fig. 1) to the movable arm (E at 6 Fig. 1) so as to exert its tensile elasticity to
hold the swell in close proximity to the picker guide spindle (G Fig. 1).
(Par. 5.) The metal coil spring (F Fig. 2) or other elastic spring or cushion-
as for instance india rubber-encompasses a portion of the aforesaid stem or
spindle, and by its expansive elasticity being exerted between the socket (C at a..
Fig. 2) and the collar, washer, or regulating nut at (6 upon the spindle-B Fig. 2)
holds the swell in close proximity to the picker guide spindle (G Fig. 2).
(Par. 6.) The divided (D Fig. 2) are regulating and lock nuts, for adjusting
and securing the swell's proximity to the picker guide spindle (G Fig. 2).
(Par. 7.) Reference paragraph to details of Fig. 1.
A Shuttle picker check swell.
BB Stem or spindle sliding in sockets.
C Perforated socket for reception of swell stem or spindle.
D Setting collar for setting swell close to picker guide spindle.
E Movable arm for regulating spring tension.
F Metal coil spring, operating by tension.
G Picker guide spindle.
H Arm for attachment to loom.
I Shuttle picker.
JJJJ Dotted lines indicating picker race.
Paragraph 8. Reference paragraph, exceptional details Fig. 2.
CC Twin sockets connected to each other by K.
D Regulating and lock nuts.
F Metal coil spring, operating by expansion.
b Affixed collar, washer, or regulating nut to communicate the elastic expansion.

page_text: Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that
what we claim is,
First. The attachment of a stem or spindle to the picker check swell, as
described in Par. 2 of Specification, and shewn in drawings, Fig. 1 and 2. A and B.
Second. The sections of aforesaid stem or spindle, as described in Par. 3 of
Specification.
Third. The aforesaid stem or spindle sliding in fixed sockets as shewn in
drawings Fig. 1. C and Fig. 2. C. C. and indicated in latter portion of Par. 3 of
Specification.
Fourth. The actuating of the aforesaid stem or spindle in the aforesaid sockets,
by a contracting or expanding metal coil, or other elastic spring, as described in
Par. 4 & 5 of Specification.
Dated this 8th day of January 1896.
