Improvements in Box Nailing Machines.
I, WILLIAM SPENCER DOIG, of 24 Franklin Street, of Brooklyn, in the
County of Kings and State of New York, United States of America, Engineer.
do hereby declare the nature of my invention to be as follows:-
This invention relates to machines for driving nails in boxes and it consists in a
rotary and vertically movable table and the means for automatically causing these
movements; and it further consists in the construction and novel arrangement of
parts as hereinafter set forth.
I have not deemed it necessary to describe means for supplying nails to the
pockets or to particularly describe the driving mechanism, as such features are
fully shown in my Patent No. 17,393 of October 13, 1891.
What I desire to have reference to in my present invention in connection with
other improvements is a supporting standard extending upwards from a base.
This standard is hollow or tubular and consists of two parts, one being horizontally
adjustable relatively to the other, as will be more fully described hereinafter.
The driving shaft having a band wheel thereon I use as a bearing at one end in
a post and at the other end in the standard.
The portion of the standard described has secured to its upper end a flange,
ring, and the upper portion has an annular flange, adapted to rest on the lower
flange. Bolts extend through slot openings in the upper flange and engage in
tapped holes in the ring. By this construction the part which carries the nail
punches and pockets, may be moved backwards or forwards to adjust the nail
pushers aud pockets in these directions; to regulate for different thicknesses of
stuff being nailed.
A cross-head is secured to a ring which is reciprocated vertically on the upper
part, by means of a rod, which is pivotally connected at its upper end to a bar
extending from a ring through vertical slots in that part of the standard. The
lower end of the rod has a crank connection with the shaft.
Arms are adjustably connected to and extend outwards from the cross-head.
At the rear end each arm has a T-shaped rib, engaging in a longitudinal T-shaped
groove, in the upper side of the cross-head, so that these arms may be adjusted
longitudinally of the cross-head to accommodate them to different sized boxes. They
may be secured as adjusted by means of thumb screws. The arms have the nail
drivers, or pushers, adjustably attached to them in the usual manner.
Arms support the usua! uail pockets. These arms at their rear ends have &
T-shaped rib to engage a correspondingly shaped groove in a fixed bar, so that
said arms may be adjusted to the proper position relatively to the arms.
A back stop is secured to the standard, below the bar. This stop serves to
prevent the boxes being nailed from being pushed too far back.
I will describe a table for supporting boxes during the process of nailing.
This table may be adjusted vertically by hand-power to bring it to its lowest
required position relatively to the nailing mechanism, and it may be adjusted
vertically to another position by automatic means. This last adjustment is caused
by a rotary movement automatically imparted to the table.
The table, has a central tubular bub-like portion, surrounding the standard and
normally resting on the top of a ring. This ring bas lugs projecting from its

page_text: inner side through vertical slots in the standard, so that said ring may have a
vertical movement on the standard; but not a rotary movement.
A nut is used, the interior thread of which engages the threaded portion of the
standard, and this nut has attached to it a hand-wheel and a ring rests normally
on the top of the nut and clips have their lower portions movably seated in
vertical grooves in the ring and coiled springs are secured at one end to the clips
and at the other end to the ring. The upper ends of the clips have inwardly
turned portions which engage over an annular rib on the hub-like portion.
The lips and springs, serve to hold the table in yielding contact with the ring
and nut so that the table may be automatically moved vertically, while the ring
and nut are at rest.
The clips are secured to a nut and have a book portion engaging in an annular
groove in the ring.
Obviously by rotating the nut, the table may be raised or lowered on the
standard.
I will now describe a means for automatically raising and lowering the table.
A short vertical shaft has bearings in arms, extending outwards from the ring,
and a gear wheel on the upper end of said shaft meshes with a gear on the
bub-like portion of the table. A ratchet wheel is secured to the shaft below the
upper arm and a pawl carrying arm is supported by, but has a rotary movement on
the shaft. This arm has at one end a ring which loosely surrounds the shaft but
it is prevented from moving longitudinally on the shaft by means of a collar
affixed to the shaft. A pawl is pivotally connected to the arm and engages with
the ratchet.
A curved lever is pivoted between its ends to a part projecting from one of the
two opposite arms extending from the ring. At its inner end the lever is slotted
and a pin extends from the end of the arm loosely through said slot.
A rod has a pivotal connection with the outer end of the lever und at the other
end is connected to a crank.
Arms extend outwards and upwards from the ring and have rollers at their
ends.
At opposite sides the table, on its under surface, is provided with ribs ; these
ribs are arranged in the arc of a circle and are adapted to engage on the rollers as
the table revolves.
In operation the table is adjusted first by means of a band-wheel to accommodate
it to the height of the end pieces of a box with one side piece thereon. At this
stage, the ribs must be on the rollers so that the box will be raised to the proper
level. The nailing mechanism is now operated to force nails through the side
piece into the end pieces, or vice versa. On the downward movement of the cross-
head the pawl will be rotated around the ratchet wheel without imparting
movement thereto; but on the upward movement of the cross-head the pawl will
be moved in the opposite direction and engaging with the ratchet wheel, will
rotate the table one-fourth revolution, and bring the rollers to bear on the under
side of the table between the ends of the ribs, thus lowering the table and allow
the opposite side or end of a box, placed on the table between the ends of the ribs,
to be nailed on.
Of course boxes to any number may be placed on the table and as the table
revolves, they will be brought to the proper position beneath the nailing
mechanism.

page_text: I, WILLIAM SPENCER DOIG, of 24 Franklin Street, Brooklyn, in the County
of Kings and State of New York, United States of America, Engineer, 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:-
This invention relates to machines for driving nails in boxes and it consists in a
rotary and vertically movable table and the means for automatically causing these
movements; and it further consists in the construction and novel arrangement of
parts as hereinafter set forth.
I have not deemed it necessary to show or describe means for supplying nails to
the pockets or to particularly show and describe the driving mechanism, as such
features are fully shown in certain Patents, notably my Patent No. 17,393 of
October 13, 1891.
In the accompanying drawing,
Fig. 1, is a front elevation of a box nailing machine embodying my improve-
ment; Fig. 2, is a vertical section thereof;
Fig. 3, is an elevation of a portion of the machine at right angles to Fig. 1 ;
Fig. 4, is a transverse section on the line 4, 4, of Fig. 1, looking upwards.
Fig. 5, is a detail portion of the machine shown in elevation.
Figs. 6, 7, & 8, are detail sectional views of the vertical movable rings;
Fig. 9, is a detail sectional view of table;
Fig. 10, is a detail sectional view of hand-wheel; and
Fig. 11, is a top view of the standard and flange showing the means of
adjustment.
Referring by letter to the drawing A, is a supporting standard extending
upwards from a base A'. This standard is hollow or tubular and consists of two
parts a, a¹, one being horizontally adjustable relatively to the other, as will be more
fully described hereinafter.
B, designates the driving shaft having a band wheel B', thereon and having a
bearing at one end in a post B³, and at the other end in the standard A.
The portion a, of the standard A, bas secured to its upper end a flange ring a³,
and the portion a', has an annular flange a³, adapted to rest on the flange a².
Bolts a', extend through slot openings in the flange a, and engage in tapped holes.
in the flange a. By this construction the part a', which carries the nail punches
and pockets, may be moved backwards or forwards to adjust the nail pushers and
pockets in these directions, to regulate for different thickness of stuff being
nailed.
C, designates a cross-head secured to a ring C, which is reciprocated vertically
on the part a¹, by means of the rod c, which is pivotally connected at its upper.
end to a bar c', extending from the ring C¹, through vertical slots ², in the part a',
of the standard. The lower end of the rod c, has a crank connection c*, with the
shaft B.
C³, shows arms adjustably connected to and extending outwards from the
cross-head C. At the rear end each arm C, has a T-shaped rib b, engaging in a
longitudinal T-shaped groove b', in the upper side of the cross-head, so that
these arms may be adjusted longitudinally of the cross-head to accommodate them
to different sized boxes. They may be secured as adjusted by means of thumb.
screws. The arms C, have the nail drivers, or pushers, C³, adjustably attached to
them in the usual manner.

page_text: C4, shows arms for supporting the usual nail pockets C. These arms at their
rear ends have a T-shaped rib 2, to engage a correspondingly shaped groove in a
fixed bar C, so that said arms may be adjusted to the proper position relatively to
the arms C.
A back stop C', is secured to the standard A, below the bar C. This stop
serves to prevent the boxes being nailed from being pushed too far back.
D, designates a table for supporting boxes during the process of nailing. The
table may be adjusted vertically by hand-power to bring it to its lowest required
position relatively to the nailing mecha, ism, and it may be adjusted vertically to
another position by automatic means. This last adjustment is caused by a rotary
movement automatically imparted to the table.
The table D, has a central, tubular hub-like portion d, surrounding the
standard A, and normally resting on the top of a ring D¹. This ring D¹, has
lugs d', projecting from its inner side through vertical slots d', in the standard A,
so that said ring may have a vertical movement on the standard, but not a rotary
movement.
D', shows a nut, the interior thread of which engages the threaded portion d³, of
the standard A, and this nut. has attached to it a hand-wheel D³.
The ring D', rests normally on the top of the nut D*.
-
Clips E, have their lower portions movably seated in vertical grooves e, in the
ring D', and coiled springs e¹, are secured at one end to the clips and at the other
end to the ring D'. The upper ends of the clips E, have inwardly turned
portions e, which engage, over an annular rib, e³, on the hub-like portion d. The
lips E, and springs, serve to hold the table in yielding contact with the ring D',
and nut D³, so that the table may be automatically moved vertically while the ring
and nut are at rest.
Clips E, secured to the nut D2, have a hook portion engaging in an annular
groove e, in the ring D'.
Obviously by rotating the nut D³, the table D, may be raised or lowered on the
standard A.
I will now describe the means for automatically raising and lowering the
table.
F, designates a short vertical shaft having bearings in arms f, extending
outwards from the ring D¹, and F¹, is a gear wheel on the upper end of said
shaft meshing with gear F, on the hub-like portion d, of the table D. A
ratchet wheel F³, is secured to the shaft F, below the upper arın f, and a pawl
carrying arm, is supported by, but has a rotary movement on the shaft F.
This arm, has at one end a ring which loosely surrounds the shaft F, but it is
prevented from moving longitudinally on the shaft by means of a collar f*, affixed
to the shaft. A pawl f, is pivotally connected to the arm f', and engages with
the ratchet F³.
F4, is a curved lever pivoted between its ends to a part projecting from one of
the two opposite arms G, extending from the ring D¹. Atits inner end the lever F,
is slotted as shown and a pin g, extends from the end of the arm f, loosely through
said slot.
A rod Go, has a pivotal connection with the outer end of the lever F, and at
the other end is connected to the crank c³.
The arms G, extend outwards and upwards from the ring D', and have rollers y',
at their ends.
At opposite sides the table, on its under surface, is provided with ribs G¹; these
ribs G, are arranged in the arc of a circle and are adapted to engage on the
rollers g', as the table D, revolves.
In operation the table is adjusted first by means of the hand-wheel D³, to
accommodate it to the height of end pieces of a box with one side piece thereon.
At this stage, the ribs G', must be on the rollers g', so that the box will be raised
to the
proper level. The nailing mechanism is now operated to force nails through
the side piece into the end pieces or vice versa. On the downward movement of

page_text: the cross-head C, the pawl will be rotated around the ratchet wheel without
imparting movement thereto; but on the upward movement of the cross-head the
pawl will be moved in the opposite direction and engaging with the ratchet wheel,
will rotate the table D, one-fourth revolution and bring the rollers g', to bear on
the under side of the table between the ends of the ribs G', thus lowering the
table and allow the opposite side or end of a box, placed on the table between the
ends of the ribs, to be nailed on.
Of course boxes to any number may be placed on the table and as the table
revolves, they will be brought to the proper position beneath the nailing
mechanisın.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:
1. In a box nailing machine, the combination with a standard and a non-rotary
driver, or punch of a table, surrounding the standard and adapted to support a
number of boxes, and having a rotary and vertical movement relative to said
standard, and means for causing said movements, substantially as specified.
2. In a box nailing machine, the combination with a standard comprising two
portions, one portion being laterally adjustable upon the other of an annular table
surrounding said standard and adapted to support a series of boxes to be nailed
successively, means for adjusting the table vertically and means for rotating it,
substantially as specified.
3. In a box nailing machine, the combination with a standard, having an
exterior screw thread, of a table having a vertical and rotary movement thereon,
a nut for causing a vertical movement of said table, a yielding connection between
said nut and table, and mechanism comprising a pawl and ratchet mechanism
operated from a driving shaft for causing a rotary and vertical movement of the
table, while the nut is at rest, substantially as specified.
4. In a box nailing machine, the combination with a standard having a threaded
portion thereon, of a rotary and vertically movable table, a threaded ring, a ring
movable vertically on the standard, arms extending therefrom, rollers in the ends
of said arms, arc-shaped ribs on the under surface of the table adapted to move
on the rollers as the table is rotated and means operated from a driving shaft for
rotating the table, substantially as specified,
5. In a box nailing machine, the combination with the table and nailing
mechanism, of the standard consisting of two tubular sections, the lower of said
sections having a threaded portion with which a ring engages to raise and support
the table, and the upper section having a flange resting on a flange of the lower
section, one of said flanges having slots and bolts passing through said slots and
engaging the other of said flanges whereby the upper section is adjustable
horizontally on the lower section, substantially as specified.
