MENTS IN LOOMS FOR WEAVING,"
"IMPROVE-
This invention relates to improved means of weighting the warp beam of loons
for weaving in which the springs heretofore commonly used are dispensed with
and the maximum efficiency of any given weight is utilised and certain and
uniform drag or friction on the beam is ensured.
According to this my invention I employ a chain one end of which is attached to
the weight lever the chain thence passes around the neck of the "ruffle" of the
bean any desired number of times and thereon its other end. in lieu of being
attached to a spring or other part of the loom as heretofore, is by a hook or other
connection attached to the pendent part of the chain above the weight so that the
chain and weight are in effect one.
Mechanism for like purpose comprises a weighting lever having an overhanging
finger or tongue, the end of the latter rests and bears upon a lever having its
fulcrum in a slot of the casting carrying the stud of the weighting lever and the
second lever herein referred to is at about right angles to the ordinary weighting
lever. Upon or forming part of the lever stud is a bracket carrying adjusting hook
to which the weighting chain is attached-the chain is passed around the neck of
the beam (covered or encased in metal) in single coil or in two or double coils and
a hook is on the chain midway between the double coils and over which hook the
chain attached to the chain hook first referred to and to the smaller lever is passed
so that whatever the position of the weight on the ordinary weighting lever its
overhanging tongue or finger bears upon the cross lever and by means of the hooks
and coils of chain the necessary drag on the beam is maintained for and during its
changing diameters..
:
Only one end of the beam requires to be weighted the axle of the beam on the
other or unweighted, end is received in an overhanging bracket whereby its
tendency to lift is overcome.

" IMPROVE-
This invention relates to improved means of weighting the warp beam of looms
for weaving in which the springs heretofore commonly used are dispensed with
and the maximum efficiency of any given weight is utilized and certain and
uniform drag or friction on the beam is ensured.
According to this my invention I employ a chain one end of which is attached
to the weight lever the chain thence passes around the neck of the "ruffle" of the
beam any desired number of times and thereon its other end in lieu of being
attached to a spring or other part of the loom as heretofore is by a hook or other
connection attached to the pendant part of the chain above the weight so that the
chain and weight are in effect one-Mechanism for like purpose comprises a
weighting lever having an overhanging finger or tongue the end of the latter rests
and bears upon a lever having its fulcrum in a slot of the casting carrying the stud
of the weighting lever and the second lever herein referred to is at about right
angles to the ordinary weighting lever upon or forming part of the lever stud is a
.bracket carrying adjusting hook to which the weighting chain is attached-The
chain is passed around the neck of the beam (covered or encased in metal) in
single coil or in two or double coils and a hook is on the chain midway between
the double coils and over which hook the chain attached to the chain hook first
referred to and to the smaller lever, is passed, so that whatever the position of the
weight on the ordinary weighting lever its overhanging tongue or finger bears
upon the cross lever and by means of the hooks and coils of chain the necessary
drag on the beam is maintained for and during its changing diameters-Only one
end of the beam requires to be weighted the axle of the beam on the other or
unweighted end is received in an overhanging bracket whereby its tendency to
lift is overcome.
Such being the nature and object of this my said invention I will now proceed
to describe the same in detail and in order that the invention may be fully
understood I have hereunto annexed 2 sheet of drawings and have marked same
with figures of reference like figures denoting like parts on the several views
DESCRIPTION OF THE DRAWINGS.
Fig: 1 is an elevation of part of a warp beam having my improved weighting
apparatus applied thereto.
Fig: 2 is an end elevation of the same, the several other parts being shewn
detached.
Tichoma modifination of fires 1 and

page_text: 13 is the second hook referred to, and over which the chain passes to the lever 3,
at 14 the chain forms a loop, or is doubled, by one portion being connected to the
other, as shewn by the bolt 15, or other connection. So that by reason of the
connection 15 the equal freedom for the to and fro or oscillating motion of
the beam is obtained and by use of the hook 13 the maximum utility of any
given weight is secured.
As a modification of the above at Fig: 3 is shewn chain or rope 16 attached to
ordinary weighting lever 1 passed round the neck of the beam 10 and attached
to the hook 20 or to the cross rail or other rigid part of the loom, the two parts
of the chain being connected as at 15, so as to obtain the necessary freedom of
oscillating motion of the beam as above described in relation to Figs 1 and 2.
Referring now to Fig: 4 at 1 is an ordinary weighting lever, 16 the chain or
rope is passed over the hook (or pulley) 13, the other end of the chain 16, being
attached to hook or cross rail 20-the hook 13 is connected to the end of the
chain 17, which is passed over and around the neck 10 of the beam, and fastened
to the cross rail at 20, or to the ordinary spring. by which arrangement the
maximum amount of utility is obtained from any given weight.
Having thus fully described the nature and particulars of this my said invention
together with the manner in which the same is to be or may be performed or
carried into practical effect I would have it understood that what I claim as my
invention is
Firstly. The apparatus comprising the levers 1 and 3 combined with the
hooks 8-13, and chain 16, constructed and applied in manner and for purpose
herein described and illustrated by drawings.
Secondly. The arrangement and combination of lever 1, and chain or rope 16
having connecting link as at 15, for purpose herein described and illustrated.
Thirdly. The combination of chain or rope 16, hook 13, and weighting lever 1,
as shewn by Fig: 4 and for purpose herein described.
In Witness whereof I the said Henry Lomax have hereunto set my hand
and seal this twenty-second day of March in the year of our Lord one
thousand eight hundred and eighty three.
