Improvements in Machines for the Manufacture of Cigar and other
Boxes..
We, MARY JONES, of 35, Staple Street, Mapperley, ELIZA ANN JONES, of
44, Pym Street, Gentlewomen, and JOHN WILLIAM BLUNDELL, 28, Owen
Street, Engineer, all of Nottingham, in the County of Nottingham, 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 :-
Heretofore in machines for the manufacture of cigar and other nailed boxes the
box walls and bottom were placed and held together in position for nailing wholly
or partly by hand which is a great loss of time and does not produce uniform
work.
Our invention has for its object the construction of a machine which overcomes
these defects and whereby cigar and other boxes can be made in a more efficient
and rapid manner than heretofore has been the case.
The said machine comprises firstly, means for the reception and guidance of the
box sides, ends and bottoms or box sides and ends only, which facilitate the automatic
and simultaneous placing of the same in position for nailing; secondly, means for
simultaneously and successively bringing and holding in position for nailing in sets
the said box parts or sides and ends only; thirdly, an improved construction of nail
driver used for nailing the said box parts together; fourthly, improved means for
feeding the nails to the said nail driver; fifthly, means for discharging automatically
the box parts nailed together.
And in order that our invention may be more fully understood we have caused to
be appended hereunto two sheets of drawings marked with letters of reference
indicating like parts in the various figures.
Fig. 1, Sheet I, is a longitudinal section, Fig. 2 a plan, Fig. 2ª a detached plan
and Figs. 3 & 4 vertical sections at lines A-B and C-D of Fig. 1 respectively,
of a machine constructed in accordance with our invention and adapted for nailing
together the box walls and bottom simultaneously and showing the position of the
movable parts of the machine after the box parts have been nailed together and
discharged.
Fig. 5, Sheet II, is an enlarged longitudinal section of the middle portion of the
said machine. Figs. 6 & 8 are longitudinal sections and Fig. 7 an end view of
the nail driver.
In carrying out our invention and referring to the figures generally, a is the body
of the machine, b the table and c the driving shaft carrying the loose and fast
pulleys d, d. Upon and below the table bare employed in a vertical line with
each other two troughs e & el adapted to receive and guide the box sides f, f' to
plunger arms a adapted to move between the said troughs. Upon the table bare
also employed in a horizontal line and at a right angle to the troughs e, e', two
plates & which, in conjunction with the table b, form also troughs which serve
to receive and guide the box ends f&f to the plunger arms 9. At the rear of
the upper trough e is employed a short distance above the back part of the table b
another trough e adapted to receive and guide the box bottoms f* to a frame / in
which is adapted to slide vertically a plunger h'. In each case one side of the said
troughs is rendered suitably adjustable so as to increase or decrease its size in
accordance with the size of box to be manufactured. For the same purpose the
plunger arms g are rendered adjustable on their block g' and the plunger /' is formed
in two parts. The box sides f¹ and ends f' & f* are forced against the plunger arms 9

page_text: and the box bottom to the frame / set by set successively by means of brackets i
under the influence of weights attached thereto by cords riding over pulleys
which brackets are adapted to slide in contact with the outer end of each row of the
said box parts, whilst the box sides f¹ descend upon the plunger arms g one by one
by reason of their own weight or by a weight placed thereon. The plunger arms g
carry each externally two plates which can be adjusted in position thereon
longitudinally at a distance from the ends of the plunger arms in accordance with
the depth of box to be made whether the box sides and ends used are the same
depth or not, the front ends of the plates k serving to engage and move the box sides
and ends against the box bottom.
Adjacent to the sides of the plunger arms g are fixed to the machine table b, see
more particularly Fig. 2, two grippers each of which carries a spring stud al
with bevelled end which receeds when the plunger arms 9 carries the box parts
forward and takes up afterwards its normal position behind the box parts so that
when the plunger arms g return the box parts nailed will be stripped off the same.
One of the said grippers a is fulcrumed to the table and held in position upon the
respective box end by means of a projection b³ formed on the movable table
part, hereinafter described, until the latter drops which allows the said gripper
to receed slightly and thus release the box parts nailed together. The plunger
block and its arms 9 are reciprocated by means of a crank disc fixed upon a
rotating shaft and by suitable connections such as rods 12 & 13 and rocking
'lever l'.
In the present instance the shaft has rotary motion imparted from the driving
shaft c by means of two pairs of bevel wheels & c¹ and the shaft c. The
plunger is lowered and raised by means of a band or chain m riding over guide
pulleys m¹, m³ & m³ and connected to a rod m one end of which rides upon the
guide pulley m³ and the other being attached by means of a bracket g² to the plunger
block g. The plunger is raised above the box bottom trough and serves to
come into contact with and force down in the frame one of the bottom f* as well
as to hold the same and the sides and ends in position when being nailed.
In order to cause the box parts nailed together to leave the machine instantly it
is formed with a movable table 6' 63, the part of which is rendered adjustable so
as to accommodate different sizes of boxes. By preference we hinge the said
movable table to the large table band raise it into position and lower it by means
of a lever n suitably fulcrumed and bearing against the underside of the table b², 3.
The outer end of this lever is under the influence of a spring n' which retains the
inner end in position underneath the said table whilst the box parts are placed and
nailed together. Connected to the said inner end of the lever n is a rod n² passing
through a hole formed in an arm g of the plunger block gl and having an adjustable
collar with which the arm g* contacts when the block gl is arriving at the end of
its outstroke so as to cause the said rod to draw the lever n from underneath the
table 1, 3, and thus allow the latter and the nailed box parts to drop.
Adjacent to the ends of the movable table ', 62, and at the back of the frame h,
is adapted to slide upon the table b respectively, a frame o, o', o' carrying a suitable
number of adjustable nail drivers p. The frames o, o', o³, are reciprocated through
the medium of a cam g and suitable connections, such as the angular levers q' under
the influence of springs q' and links q³ and the frame o² through the lever q', the
frames o&o being rendered adjustable relative to the plunger arms 9 by means of
the links to accommodate the various sizes of box to be manufactured. The cam q
has rotary motion imparted from the driving shaft c by means of a pair of bevel
wheels c³.
Each of the said nail drivers consist of a tubular stud p, see Figs. 6, 7 & 8,
Sheet II, secured to the respective frames and formed on its top with a cavity p
covered by a lid p' which facilitates examination in case of need. In the back end
of the tubular stud p is employed a spring u adapted to act upon a piston u¹
employed in the front end thereof. Through the back end of the piston u is
formed a hole u³ communicating with a groove u formed in the front end thereof

page_text: in which hole 2 is adapted to slide a driver r secured to the back end of the-
tubular stud p. The latter is also furnished with a piu or screws engaging in a
grooves formed in the piston which prevents the latter leaving the tubular-
stud p.
Into the back end of the cavity p¹ is fixed a curved metal tube t to which
is attached a flexible pipe t'; see Figs. 1, 2, 3 & 4, connected to the nail feeding.
tray adapted to oscillate on a bracket so as to incline alternately forwards and
backwards and thus agitate the nails and secure a regular feeding of the same.to.
the nail drivers p. The front end of the piston u¹ is furnished with an inter-
changeable plate, the outer edge of which is slightly higher than the base of the
groove s'. This plate serves to present each nail in a perfect horizontal position
to the box part to be nailed and thus ensure the correct driving of the same. The
oscillation of the nail tray * is effected by means of a chain w hooked onto the.
chain m.
The operation of the machine is as follows:-
When the driving shaft c of the machine is set in rotation, the plunger block gl
moves forward takes with it a set of the said box walls and releases the rod n² so as
to allow the spring n' to contract and cause the lever n to raise the table,, in
position. In the meantime the plunger brings the box bottom positioned below
it down upon the table 1, 2, and the plunger arms g then arriving at the end of
their in stroke place the box walls against the bottom in position for nailing which
is effected by the drivers p, the nails already depositioned in the piston grooves u³,
see Fig. 6, being thrust into the box parts simultaneously whilst in the meantime.
fresh nails are falling from the cavities p¹ upon the drivers r which on the return
of the latter are allowed to fall into the grooves u in the pistons u ready for the
next thrust. The plungers 9 & h' then return and when arrived at the end of their
outstroke the movable table 6', 6', supporting the nailed box parts drops and permits
the latter to leave the machine.
The machine described may also be used for nailing together the walls of boxes.
only by simply disengaging the plunger h', the nail driver frame o' and respective
feed or a machine may be similarly constructed for the said purpose only.
It will also be understood that the position of the troughs described and parts
operating in conjunction therewith may be varied without departing from the nature
of our invention.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed we declare that what we
claim, is―
