PROVISIONAL SPECIFICATION.
Improvements in Pattern Chains or Pattern Surfaces for use in
connection with Looms.
EDWARD HILL of Ethel Street, Keighley in the County of York,
Draughtsman do hereby declare the nature of this invention to be as follows,
that is to say :—
It consists of improvements in pattern chains or pattern surfaces applicable for
use in connection with looms for governing or controlling the movements of the
heddles or the shuttle boxes or picking mechanism thereof, whereby same may be
cheaply produced while their efficiency is in no way diminished.
To attain this object I make use of metal cams or tappets arranged to be
mounted upon a pin or tube and in the part of these cams that surrounds this pin
or tube, I form additional openings for the reception of prongs or longitudinal pro-
jections formed on a spacing hoop that I mount upon the pin or tube to intervene
between the cams, the outermost of these spacing hoops on each end of the tube
being arranged so that its prongs will enter corresponding openings in the links
joining one pin or tube to another to form the pattern chain, by which means
all the cams on each tube are held in position by being coupled to the links
at each end as is required or as is necessary to enable them to perform their
respective functions in the governing or controlling of the motor parts of the loom
as is well understood.
By forming these cams and spacing hoops as above described I am enabled to
stamp them as also the links, out of sheet metal and so produce them in an
expeditious and comparatively inexpensive manner.

COMPLETE SPECIFICATION..
Improvements in Pattern Chains or Pattern Surfaces for use in
connection with Looms.
EDWARD HILL of Ethel Street, Keighley in the County of York,
Draughtsman, do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement, that is to say :-
It consists of improvements in pattern chains or pattern surfaces applicable for
use in connection with looms for governing or controlling the movements of the
heddles or the shuttle-boxes or picking mechanism thereof, whereby same may
be cheaply produced while their efficiency is in no way diminished.
In order that my said invention may be more readily understood I have here-
unto appended a sheet of drawings illustrative thereof to which by figures and
letters reference is made in the following description.
Figs. 1 and 2 are side and sectional end elevations, respectively, shewing a
pattern barrel having a pattern chain, made in accordance with my invention, in
connection with it.
Fig. 3 is a perspective view enlarged scale shewing a bar or tube upon which my
improved parts are mounted.

page_text: Figs. 4, 5, 6, 7, 8 and 9 are drawings in detail of parts hereinafter fully
described.
Figs. 10 and 11 are drawings illustrative of the chain-links made in accordance
with my invention.
To attain the object of this invention I make use of metal cams or tappets a
arranged to be mounted upon a pin or tube band in that part of these cams a
which encircles the pin b, I form additional openings a' for the reception of prongs
or longitudinal projections c¹ formed on a spacing hoop c that I mount upon the pin
or tube b to intervene between the cams a, the outermost of these hoops c on cach
end of the tube b being arranged so that its prongs c¹ will enter corresponding
openings d¹ formed in the links d which are for joining one pin or tube b to another
to form the pattern chain, by which means all the cams a on each tube bare held
in position, by being thus coupled to the said links dat each end, as is required
or as is necessary to enable them to perform their respective functions in the
governing or controlling of the motor parts of the loom as is well understood.
By forming these cams a and spacing hoops as above described I am enabled
to stamp them as also the links d, out of sheet metal, the stamped blank of the cam a
being shewn by Fig. 5 while the blank shewn by Figs. 7 and 9 are those from
which the spacing hoops are made by the same being folded into the shape shewn
by Figs. 6 and 8.
Those prongs c on the hoops c which are for fitting into the cams a or into the
links d may be made sufficiently long, as shewn by Figs. 6 and 7, so that they
may be bent or folded over the edges of these said cams and links as shewn by
Figs. 4 and 11 and be thereby firmly attached to them or they may be left short,
as are those at c', Figs. 8 and 9, and be therefore only loosely mounted on the
tubes between the cams a. By forming the cams a and hoops c out of sheet
metal as above described I am enabled to produce them in an expeditious and
comparatively inexpensive manner.
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.
1. The method of forming or constructing pattern surface cams substantially as
herein specified.
2. Spacing hoops for use in connection with pattern surface cams the same
being formed and constructed substantially as herein set forth and described.
3. Cams, hoops and links to be used as pattern surface mechanism the same
being formed and constructed substantially as herein specified.
