ARTHUR BEEDHAM, of 13 Albert Street, West Failsworth, near Oldham in the
County of Lancaster, Mechanic do hereby declare the nature of this invention to
be as follows:
:-
The improvements relate to dobbies for the purposes of textile manufacture and
consist in bringing the action of the dobbie, direct from the lifting hooks of the
machine to the heald shafts of the loom, without the intervention of jacks or levers,
and by simplifying the method by which, the cords or lags, do communicate motion,
to the hooks of the machine, and so direct to the heald shafts, in a double lift
mauner.

To attain these ends I provide an arrangement of bell-cranks, two for each
healdlifting" hook of the machine. These bell cranks are all pivotted upon one
shaft, and their outer ends, which is also their longer and consequently heavier
ends, when the beald shafts are down, all rest upon a bar, immediately above the
card or lag cylinder. This cylinder if cards are used, is made to descend from its
acting position, turn round and ascend with a new card to actuate the bell cranks,
which in this instance have each a peg or pin in it opposite a hole in the cylinder.
But if lags are used the cylinder is made to turn round every two picks, and the
pins or pegs are in the lags, which actuate the bell cranks, and so the needles and
hooks of the machine, much in the usual way, only no springs are required to attain
these motions.
When the bell cranks are actuated in either of these ways they, by their forked
ends, each move a horizontal needle, which moves a perpendicular hook, on, or off,
one of the grifes, of which there are two, the one ascending, and the other
descending, at the same time,-each grife has a hook for every shaft of heald the
machine is capable of working, and there is a bell crank and needle for each grife
hook. These grife hooks are formed with a long slot, in their lower ends, and
between them 1 place another hook called the "healdlifting" hook which is
formed with a teehead or crosshead one end of which crosshead is let into the slot
of a grife hook of the one grife, and the other end of the crosshead is let into the
slot of a grife hook of the other grife, as the grifes are rising and falling, these
grife hooks are level at the half lift, and if the same shaft, that was up last pick
has to be raised for the next succeeding pick, then the ascending grife hook, takes
the crosshead of the "healdlifting" hook from the descending one, and the same
shaft is, in this manner lifted as many picks in succession as are wanted.
By turning a small shaft, which I provide for the purpose, the weaver can bring
all the heald shafts level, to facilitate, the drawing in of yarn.
Dated this 30th day of May 1894.

page_text: An improved Double-lift Dobbie.
I ARTHUR BEEDHAM of Highfield Terrace High Street Droylsden near
Manchester in the County of Lancashire Mechanic late of 13 Albert Street
West Failsworth near Oldham do hereby declare the nature of this invention
and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :-
The improvements relate to dobbies for the purpose of textile manufacture, and
consist in bringing the action of the dobbie direct from the lifting hooks of the
machine to the heald shafts of the loom without the intervention of jacks or leavers
and by simplifying the method by which the cards or lags do communicate motion
to the hooks of the machine and so direct to the heald shafts in a double lift
manner.
To attain these ends I provide an arrangment of bell cranks two for each heald
lifting hook of the machine, these bell cranks are all pivoted upon one shaft and
their outer ends which are also their heavier and longer when the heald shafts are.
down all rest upon a bar immediatly above the card or lag cylinder. This
cylinder if cards are used is made to descend from its acting position turn round
and ascend with a new card to actuate the bell cranks which in this instance have
a pin which lifts up and down through a plate for that purpose these pins on the
upper side come opposite the bell cranks, and on the lower side of pin plate come
opposite a hole in the cylinder and when the cards are not perforated opposite a
hole in the cylinder the pin is lifted which actuate the bell cranks, but if lags are
used the cylinder is made to turn round every two picks and the pins or pegs are
in the lags which acuate the bell cranks and so the needles and hook of the
machine much in the usual way only no springs are required to attain these.
motions. When the bell cranks are actuated in eather of these ways they by their
forked ends each move a horzontal needle which moves a perpendicular hook on
or off one of the grifes of which there are two, the one asending the other
descending at the same time each grife has a hook for every shaft of heald the
machine is capable of working and there is a bell crank and needle for each grife
hook. These grife hooks are formed with a long slot in their lower ends and
between them I place another hook called the heald lifting hook which is formed
with a tee head or cross head one end of which crosshead is let into the slot of the
grife hook of the one grife and the other end of the crosshead is let into the
slot of a grife hook of the other grife as the grifes are rising and falling these
grife hooks are level at the half lift and if the same shaft that was up last
pick has to be raised for the next succeeding pick then the ascending grife
hook takes the crosshead of the heald lifting hook from the descending one and
the same shaft is in this manner lifted as many picks in succession as are
wanted. By turning a small shaft which I provide for the purpose the weaver
can bring all the heald shafts level to facilate the drawing in of yarn.
But that the improvements may be better understood I will by the aid of the
accompanying drawings proceed more fulley to describe means employed by me.

Having now particulary described and ascertained the nature of my said inven-

claim is
1. The construction of dobbies in such manner that the lags or cards operate
upon the bell cranks.
2. The construction of dobbies in such manner that the grife hooks lift the
heald lifting hooks with a teehead or crosshead.
