THE
I, GEORGE HODGSON, of Laycocks Mill Thornton Road, Bradford in the County
of York Machine Maker, do hereby declare the nature of my invention for
"IMPROVEMENTS IN THE METHOD OF AND APPARATUS FOR. ACTUATING
SHUTTLE BOXES OF LOOMS," and in what manner the same is to be performed.
to be particularly described and ascertained in and by the following statement:-
The object of this invention is to improve the means eniployed for raising, and
lowering the shuttle boxes of looms, and to lock the same in any position after a
change takes place, and consists in securing on one of the loom shafts, a tappet, which
operates levers that actuate through catch rods, lock plates,, and eccentrics other
levers that are attached by rods to the shuttle drop boxes, which are raised or
lowered according to the direction in which the eccentrics are turned.
In the accompanying drawings Fig. 1, represents a sectional elevation through
line a. b. on plan and Fig. 2, is a plan of the eccentrics, lock plates and levers.
The apparatus is fixed at both ends of the loom, so the description given to one
end applies to the other.
On to the bottom or picking shaft of the loom I secure a tappet A, which acts
upon the lever B, one end of which is mounted on a stud at C, the other end
working in guide grate D. Projections are formed at each side of the lever at B¹,
and B, and between the same are placed two catch rods E, and E¹ at each side of
the lever, which are connected to the studs at each side of the centre pin lock
plates G and G. The lock plates G and G¹ gear with the respective eccentrics F
and F', the straps of which are connected to the respective levers H and H' the
former is mounted on stud J, as fulcrum, and near to the end is secured a stud K
upon which the other lever H' is mounted. This lever is extended and connected
by a suitable rod to the drop boxes in the ordinary manner which are actuated as
follows.
In connection with each pair of catch rods E and E' is a lever L, mounted on a
stud as fulcrum, and attached to the heald machine the respective rods M, in the
ordinary manner. The opposite end of each lever at L' is arranged with projections
that clip the catch rods E and E' so that when either of the levers L are moved,
the catch rods E and E¹ connected therewith are moved in a corresponding
direction, and the former brought into contact with the respective projections B¹

page_text: and B² on lever B. In the drawing the catch rod E, is shewn in contact with the
projection B¹ on lever, and when the latter is raised by the revolving tappet A, the
lock plate G, will be moved until the indentation at G is in the position as shewn
by the indentation G" the teeth on the lock plate turning the pinion and
eccentric F, in the direction of the arrow, causes the lever H, to move on its
fulcrum J, and the end of lever H¹ to rise, and thereby to raise the drop boxes one
hole or division; and' should the same be required to raise another hole, the other
rod E, in connection with eccentric G' is actuated by the other lever L, in the same
manner by which the eccentric F¹ is moved and the opposite end of lever H¹, and
the shuttle drop boxes connected thereto further elevated.
As will be easily understood, when the catch rods, E, are raised by the lever B,
the respective catch rods E¹, will at the same time be lowered; and when the
shuttle drop boxes are lowered, one or both catch rods E¹ is or are moved by the
lever or levers L, so that the said catch rod ends are over the projections B2 on
lever B, which when raised by tappet A, the motion of the levers H, and H¹ are
reversed thereby lowering the shuttle drop boxes, which are locked in the respective
positions for receiving and delivery of the shuttles by the swells N, on brake
straps P, entering the indentations G or G³ formed in the circumference of lock
plates G and G¹.
.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I, declare that what
I claim is
The combination of the lock plates and eccentrics with the levers H and H¹
substantially in the manner shewn and for the purpose described.
The combination of the levers H and H¹ with the eccentrics F and F¹ for the
purpose set forth.
