IMPROVEMENTS IN SELF-STOPPING BEAMING MACHINES
Year: 1877

page_text: LETTERS PATENT to Edmund Tweedale, of Accrington, in the County of
Lancaster, Machine Works Manager, for the Invention of "IMPROVEMENTS IN
SELF-STOPPING BEAMING MACHINES."
PROVISIONAL SPECIFICATION left by the said Edmund Tweedale at the
Office of the Commissioners of Patents on the 11th December 1877.
EDMUND TWEEDAle, of Accrington, in the County of Lancaster, Machine Works
Manager. "IMPROVEMENTS IN SELF-STOPPING BEAMING MACHINES."
This Invention relates to the construction and application of mechanism adapted
and applied to machines aforesaid for the purpose of facilitating and easing the
turning the barrel by hand (when necessary for purpose of taking an end or ends
up) by disconnecting the said barrel from the gear of the "nip rollers," or other
going part of the machine.
According to this my Invention I apply to the "diagonal" shaft a clutch box or
clutch bosses; one of such bosses is connected with the clip end of a fulcrum lever,
the other end of the said lever is heavier or counterbalanced, and so long as the
machine continues running, the said clutch bosses continue in gear, and together
with the lever are supported in position by an arm on the main shaft, or by a part
of the stop motion. When an end is down or broken, the knocker off acts, and the
support is withdrawn from under the heavy end of the lever referred to, and on the
barrel being slightly reversed, the notches or clutch of the bosses separate, and by
the action of the heavy ended lever are entirely separated, so as to leave the barrel
perfectly free to be moved, as desired. On restarting, the arm on the main shaft, or
on the knocker off, lifts the heavy ended lever, and so the clutches are brought
together again, and the diagonal shaft becomes operative in relation to the nip
rollers as before.
Or the clutch box or clutch bosses may be on the main shaft, and operated from
the stop motion, as and by means described.

the said Edmund Tweedale in the Great Seal Patent Office on the 11th June
1878.
EDMUND TWEEDALE, of Accrington, in the County of Lancaster, Machine Works
Manage "IMPROVEMENTS IN SELF-STOPPING BEAMING MACHINES."
This Invention relates to the construction and application of mechanism adapted
and applied to machines aforesaid for the purpose of facilitating and easing the
turning the barrel by hand (when necessary for purpose of taking an end or
"ends" up) by disconnecting the said barrel from the gear of the "nip rollers," or
other going part of the machine.
According to this my Invention I apply to the "diagonal" shaft a clutch box or
clutch bosses; one of such bosses is connected with the clip end of a fulcrum lever,
the other end of the said lever is heavier or counterbalanced, and so long as the
machine continues running, the said clutch bosses continue in gear, and together
with the said lever are supported in position by an arm on the main shaft, or by a
part of the stop motion. When an end is down or broken, the knocker off acts,
and the support is withdrawn from under the heavy end of the lever referred to,
and on the barrel being slightly reversed, the notches or clutch of the boss separate,
and by the action of the heavy ended lever are entirely separated, so as to leave
the barrel perfectly free to be moved, as desired.
On restarting the machine the arm on the main shaft or on the knocker off lifts
the heavy ended lever, and so the clutches are brought together again, and the
diagonal shaft becomes operative in relation to the nip rollers as before.
Or the clutch box or clutch bosses may be on the main shaft, and operated from
the stop motion, as and by means described.
Such being the nature and particulars of this my Invention, will be fully under-
stood by the following description, aided by the two Sheets of Drawings annexed,
of which,
Fig. 1 (Sheet 1) is a side elevation; Fig. 2, a front elevation.
Fig. 3 (Sheet 2), a side elevation; Fig. 4, a front elevation.
Like letters referring to like parts in the several views.
According to this my Invention I apply to the "diagonal" shaft at A a clutch
box or clutch bosses B; one of such bosses is connected with the clip end C of a
fulcrum lever D, the other end E of the said lever is heavier or counterbalanced, and
so long as the machine continues running, said clutch bosses continue in gear, and
together with the said lever D are supported in position by an arm F on the main
shaft, or by a part of the stop motion. When an end is down or broken, the knocker
off G acts, and the support is withdrawn from under the heavy end of the lever
referred to, and on the barrel H being slightly reversed, the notches or clutch of
the bosses separate, and by the action of the heavy ended lever D are entirely
separated, so as to leave the barrel H perfectly free to be moved as desired.
On restarting the machine the arm on the main shaft, or on the knocker off G,
lifts the heavy ended lever D, and so the clutches B are brought together again, and
the diagonal shaft A becomes operative in relation to the nip rollers J, as before.
Or the clutch box or clutch bosses B, Figs. 3 and 4, may be on the main shaft A¹,
and operated by heavy ended lever D (supported by an arm F) from the stop
motion G, as and by means described.
The Drawings shew the clutch bosses separated, and the barrel H free to be turned
by hand.
Having thus fully described the nature and particulars of this my said Invention,
together with the manner in which the same is to be performed or carried into
practical effect, I would have it understood that I do not claim any of the parts per
se; what I do claim is, the application and employment of the lever D (or its

page_text: equivalent) operated from the knocker off G, so as to disconnect the clutch bosses
(or clutch box) B, as illustrated, and for purpose described.
In witness whereof, I, the said Edmund Tweedale, have hereunto set my
hand and seal, this Sixth day of June, in the year of our Lord One
thousand eight hundred and seventy-eight.
Witness,
EDWARD WILLIAM HORNE,
Globe Works,
Accrington.
