PROVISIONAL SPECIFICATION left by the said Cornelius de
Bergue at the Office of the Commissioners of Patents, with
his Petition, on the 3rd December 1852.
I, CORNELIUS DE BERGUE, of Manchester, in the County of Lancas-
ter, Engineer do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN AND APPLICABLE TO LOOMS FOR WEAVING," communicated
to me by a foreigner residing abroad, to be as follows, reference being
had to the Drawings annexed hereto; Figure 1, being the side or
end elevation of the loom :-
My Invention consists, first, in an improved method of driving, by
which I ain enabled to drive two looms placed end to end by one
strap or belt. It is accomplished by driving the first or main pulley

page_text: (61), of the loom by another friction pulley covered with leather (a¹),
which is fixed upon a counter shaft (a) placed between the two
looms. The advantages of this method are that of dispensing with
one strap or belt, and the means which it affords by very slight
motion of stopping or starting the driving power.
2nd. In an improved heald motion or apparatus, the object of
which is to give more time for the shuttle to pass through the "shed."
It is accomplished by means of an excentric (E), and oval wheel (E'),
working in each other, one of which has a crank pin (E2) inserted.
This gives motion to a toothed rack (E³), which toothed rack gives
an oscillatory or vibratory movement to a wheel fixed on a roller or
shaft (F), to which the healds (F2) are connected. From the vibratory
roller or shaft (F), just referred to, motion is taken to a vibrating beam
(G), over which the yarn or warp passes; and this (as before stated)
having motion from the vibrating roller or healds motion, acts si-
multaneously with the healds, and keeps the warp or yarn at the same

degree of tension in every position the healds assume.
motion or vibratory shaft or roller (F), also gives motion, (by means
of a cam (K³), upon the said roller or shaft), to a lever (K), in con-
nection with the picking motion to be again hereafter referred to.
3rd. The peculiar picking motion for driving the shuttle through
the shed.
The motion for this purpose is derived from that of the motion of
the "slay sword" (H) or radius arm, upon which the slay (H2) of
the loom oscillates; the end of a lever (I) carried on the sword (H),
of the slay, is made at the back motion of the "slay" from the cloth,
and at the proper time to strike against a tappet or projection fixed
on a lever (K¹), before referred to as actuated by a cam (KB), on the
vibratory roller or shaft (F), which gives to it a violent blow, which
is transmitted through the said lever (I,) to the picking rod (L)
which oscillates with the slay, and through it and other parts, to the
shuttle, driving it through the shed.
4th. The "brake" apparatus for stopping the loom.
5th. The form and mode of fixing the spring of the sliding
roller. temple without bolts; the spring is of the "bow" form, the

page_text: ends acting against the slides of the temple, and the back against a
part of the framing of the loom, being placed in an horizontal po-
sition across the loom.
6th. The application of a "brake" to the yarn beam (Q), which
permits the yarn beam to have a free delivery during the motion of
the slay from the cloth, and prevents delivery during the opposite
motion of the slay. It is actuated from the slay sword (H) of the
loom by means of a rod (Q³), and belt (Q2), passing partly round a
brake "pulley" (Q'), fixed on the yarn beam.
7th. The taking up motion is a positive one actuated from the
shaft or centre (T) of the oval wheel (which gives motion to the
healds & other parts), by an excentric placed thereon and a con-
necting rod T, which gives intermittant forward motion (when the
slay of the loom is retiring from the cloth) to the ratchet wheel T²,
which transmits its motion forward through a series of toothed
wheels to the emery roller (R), and thus advances the cloth each
pick.
8th. The mode of constructing the framing of the loom by facing
the cross stays of the loom and the corresponding parts of the end
or side frames, so that when screwed together the framing is square
and rigid, & also in the general arrangement & combination of the
parts of the loom.
