HENRY HARRIS LAKE, of the firm of Haseltine, Lake, and Co., Patent Agents,
Southampton Buildings, London, "IMPROVEMENTS IN AND RELATING TO BOBBIN
FRAMES FOR LOOMS [A communication to him from abroad by Richard
S. Cookson of Philadelphia, Pennsylvania, United States of America]
This Invention relates to bobbin frames, more particularly to those adapted to
work in connection with Brussels carpet looms; and the said invention consists
essentially in supporting the bobbin upon loose friction wheels arranged in the
frame and independent of the bobbin; it also consists partly in minor details of
construction hereinafter set forth.
Heretofore it has been customary to put an axle or pin through the spindle-hole
in the bobbin or spool with the end protruding to form an axle to work in vertical
slots in the frame which extended slightly below the centre of the bobbin, and the
bobbin was further supported upon a plate secured upon the bottom of the frape.
This device was adapted to produce friction on the bobbin and prevent its easy
rotation. But in time the support or plate on the bottom of the frame wore down
and the bobbin was then supported upon its axle in the slots without any practical
meaus for producing sufficient friction to accomplish the required result. There was
also considerable difference. in the amount of friction, due to the fact that the
pressure of the spool was always vertically downward upon the friction support,
hence the amount of friction varied according to whether the spool was full or
nearly empty

page_text: t
According to this invention the amount of friction is practically constant and
independent of the quantity of material on the spool and the devices are not liable
to wear out. Since the friction is practically constant there is little or no variation
in the tension under which the warp is put.
In carrying the said invention into practice I provide a frame which consists of
two side pieces joined together by cross pieces. I also provide supporting wires
over which the warp is drawn by a tension weight and also by the loom. The
bobbins or spools have no axle or pin but simply rest upon friction wheels carried
upon shafts or rods. The edges or flanges of the bobbin run upon the friction
wheels. If two wheels are used to support the bobbin they are put in the frame
at a distance apart which is less than the diameter of the flange of the bobbin.
When more than two sets of friction wheels are used they may be set so as all to
bear upon the bobbin flange. If one set of friction wheels alone is to be used, a
support of wood or other material is placed upon the frame so that the bobbin will
be supported upon it and also upon the friction wheels. In all of these cases-
there is no support for the bobbin against displacement, other than the friction
wheels.
"
The warp passes from the bobbin over one of the supporting wires next to the
said bobbin, then under the aforesaid weight, over the other wire, and finally to the
loom. As the warp is used up and drawn from the bobbin it will gradually work
its way to alternate sides of the bobbin, but it is prevented from becoming tangled
or caught in the said flanges or friction wheels by the tension weight which is
arrested in its lateral movement by the friction wheels.
The friction wheels may be fast upon their shafts, which latter may revolve, or
they may be loose thereon, and for cheapness they may be slipped on loosely and
kept apart by a loose sleeve in the middle and loose washers on the outside, and
between them and the sides.

projects below the said wires.
The friction wheels may be fast upon their shafts, which latter. may revolve, or
they may be loose thereon, and for cheapness they may be slipped on loosely and

foreign correspondent, and the manner of performing the same, I wish it understood
