Mason, my executors, administrators, and assigns, should at any
time agree with, and no others, from time to time and' at all
times thereafter during the term therein expressed, should and
lawfully might make, use, exercise, and vend," within the United
Kingdom of Great Britain and Ireland, the Channel Islands, 'and
Isle of Man, an Invention for "IMPROVEMENTS IN LOOMS FOR WEAVING,"
upon the conditions (amongst others) that I, the said John Mason,
by an instrument' in writing under my hand and seal, should parti-
cularly describe and ascertain the nature of the said Invention, and
in what manner the same was to be performed, and cause the same
to be filed in the Great Seal Patent Office within six calendar
months next and immediately after the date of the said Letters
Patent.
NOW KNOW YE, that I, the said John Mason, do hereby declare
the nature of my said Invention, and in what manner the same is
to be performed, to be particularly described aud ascertained in and
by the following statement and accompanying Drawings (that is to
say):
My Invention consists in the application of ball and socket joints
to the swords, cranks, and picking motions of looms. In the ac-.
companying Drawing, Fig. 1, represents a partial section of a loom

page_text: with the improvements applied; and Fig. 2, a plan view of the same.
Upon the lower end of the swords a, a, are affixed balls b, b, turning
in sockets c, c, formed upon brackets affixed to the framework,
which balls are kept within the sockets by cap pieces d. Upon the
crank rod f, is also constructed a ball g, adapted to a socket formed
in the sword, the two parts being kept together by means of a cap
h, in which a slit is made, in order to provide for the vibration of
the crank rod. The picking rods are shewn at i, provided with
balls j, adapted to sockets k, and surmounted by caps, which are.
however, according to the Drawing, removed. I have shewn a par- .
ticular method of constructing the joints. I do not, however, confine
myself thereto; that which I claim as secured to me, being the
application of ball and socket joints to the swords, cranks, and
picking motions of looms.
In witness whereof, I, the said John Mason, have hereunto
set my hand and seal, this Twenty-ninth day of July, in the
year of our Lord One thousand eight hundred and fifty-
three.
JOHN MASON. (L.S.)
