PROVISIONAL SPECIFICATION.
An Improvement in Box Nailing Machines.
We, WILLIAM COLLIER JAMES, of Hillsborough, Plymouth, Manufacturer, and
REUBEN MYNARD, of 5 St. Judes Road, Plymouth, Foreman, do hereby declare the
nature of this invention to be as follows:-
This invention has for its object an improvement in box nailing machinos.
In these machines the nails are brought forward as required by carriers and these
drop them into guide passages or nail guides. The nail guide leads the nail down and
delivers it into a groove where it lies in front of a plunger. The plunger by the
depression of a treadle is caused to advance and it thrusts the nail in front of it into
the wood which is to be nailed together.
Now our improvement relates to the construction of the nail guides which lead the
nails down from the carriers.
These nail guides are mounted on a foundation plate which when in use is adjustably
clamped on to the machine in such a position that the nails drop in at the upper ends
of the guides. The plate carries three or it may be other number of nail guides and
these are all (excepting one which may be fixed) pivoted to the foundation plate in
such manner that the nail guides may be inclined so that without displacing the month
or upper end the lower or delivery end may be set to any position or to any distance
from the neighbouring guide that the work may require. The guides are also made
telescopic so that the length may be adjusted to the inclination and the lower end set
down to the proper level. The nozzle or delivery end of the nail guide is also so
jointed to the other parts that it can be set into position to direct the nail passing
down through it truly along the groove into which it has to be dropped.
The point of the nail is controlled by the guide passage nearly until it reaches the
groove and the head of the nail becomes free from the guide and able to fall down into
the groove about at the time when the point meets the floor of the groove. A plate
which is hinged to the foundation plate covers the ends of the plungers when they
retire but lifts to allow them to advance. This plate aids in guiding the head of the
nail to its place in front of the plungers. The head falls from the nail guide on to
this plate and then passes on into the groove. This hinged plate is capable of adjust-
mont by sliding forward or backward according to the length of nail in use.
Thus by our invention we provide one attachment carrying all the nail guides in
use and these nail guides are adjustable to suit both the size of the nail and the
position of the nail in the work; whereas heretofore each nail guide has been a
separate attachment and as the nail guide was incapable of adjustment to the size of
the nail the machine has been provided with nail guides varying in construction not
only to suit the size of nail but to adapt them to the position of nail when about to be
driven into the .box.

COMPLETE SPECIFICATION.
An Improvement in Box Nailing Machines.
We, WILLIAM COLLIER JAMES of Hillsborough, Plymouth, Manufacturer, and
REUBEN MYNARD of 5 St. Jude's Road, Plymouth, Foreman, 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 has for its object an improvement in box nailing machines.

page_text: In these machines the nails are brought forward as required by carriers and these
drop them into guide passages or nail guides. The nail guide leads the nail down and
delivers it into a groove where it lies in front of a plunger. The plunger by the
depression of a treadle is caused to advance and it thrusts the nail in front of it into
the wood which is to be nailed together.
Now our improvement relates to the construction of the nail guides which lead the
nails down from the carriers.
These nail guides are mounted on a foundation frame which when in use is
adjustably clamped on to the machine in such a position that the nails drop in at
the upper ends of the guides. The frame carries three or it may be other number
of nail guides and these are all (excepting one which may be fixed) pivoted to the
foundation frame in such manner that the nail guides may be inclined so that
without displacing the mouth or upper end the lower or delivery end may be set
to any position or to any distance from the neighbouring guide that the work may
require. The guides are also made telescopic so that the length may be adjusted
to the inclination and the lower end set down to the proper level. The nozzle or
delivery end of the nail guide is also so jointed to the other parts that it can be
set into position to direct the nail passing down through it truly along the groove
into which it has to be dropped.
The point of the nail is controlled by the guide passage nearly until it reaches
the groove and the head of the nail becomes free from the guide and able to fall
down into the groove about at the time when the point meets the floor of the
groove. A plate which is hinged to the foundation frame covers the ends of the
plungers when they retire but lifts to allow them to advance. This plate aids in
guiding the head of the nail to its place in front of the plungers. The head falls
from the nail guide on to this plate and then passes on into the groove. This
hinged plate is capable of adjustment by sliding forward or backward according to
the length of nail in use.
Thus by our invention we provide one attachment carrying all the nail guides
in use and these nail guides are adjustable to suit both the size of the nail and
the position of the nail in the work; whereas heretofore each nail guide has been
a separate attachment and as the nail guide was incapable of adjustment to the size
of the nail the machine has been provided with nail guides varying in construction
not only to suit the size of nail but to adapt them to the position of nail when
about to be driven into the box.
In order that our said invention may be fully understood and readily carried into
effect we will proceed to describe the drawings hereunto annexed.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a front elevation showing the principal parts of a box nailing machine
provided with our nail guide attachment.
Figure 2 is a section on the line 2, 2, in Figure 1.
Figures 3 and 4 are sections on the lines 3, 3 and 4, 4 in Figure 2 respectively..

page_text: notches e e³ is an incline at the other end of the bar e and 9 is a finger which
from time to time comes against the incline and thrusts the bar e a short distance
from left to right. The bar e then carries the nails which are lodged in the recesses e¹
to the holes h and the nails fall through these holes into the nail guides the
construction and arrangement of which is more especially the subject of our inven-
tion. The nails fall finally into grooves formed in the bars i ii.
The nails
are received into the grooves in front of the plungers kk which slide in the
grooves. The plungers are held in a transverse groove formed in the driving
plate 1. A to and fro movement is imparted to the driving plate and when nails
have been laid in the grooves the plungers are made to advance to the front
ends of the grooves driving the nails before them into the wood which is held in
position to receive the nails. The plungers then retire together with the driving plate..
m is a right and left hand screw passing through the bars iii. The outer bars work
as nuts on the screw and by turning the screw the distance between these bars is
adjusted to the requirements of the work. The middle bar i has no screw thread and
is held stationary between collars on the screw m. The finger g is fixed upon the
driving plate and moves with it.
To the machine as above explained with reference to the drawings we lay no claim..
We will now proceed to the further description of the nail guide attachment.
The foundation frame of the nail guide attachment consists of two plates n and o
connected the one with the other at the ends and forming a rectangular frame open at
the top and bottom. To the front of the foundation frame a flap p is jointed at p¹ ;
by this flap the frame is adjustably attached to the machine by the screws qq which
pass through slotted holes in the flap so that the nail guide attachment may be set
higher or lower to adjust it to suit the length of the nail in use.
The foundation frame is free to turn about the joint p¹ so that it can yield to the
driving bar when it comes into contact with the parts which the frame carries.
Within the foundation frame between the plates n and o the troughs rr forming the
upper parts of the nail guides are received; they are so placed that the nails dropping
through the holes are received into the troughs and the nails descend through
the troughs into the grooves. The outer nail troughs are pivoted to the back
plate o at o o' and the troughs can turn about these pivots. The centre nail trough
may be fixed in the frame between the plates n and o as this trough does not require
lateral adjustinent. The outer nail troughs are made with telescopic sides and the
lower parts 1 can slide upon the upper, so that the length of the trough can be
adjusted.
r
The delivery nozzles ss of the nail guides are enclosed on three sides and open
at the botton; the outer ones are connected by joints s¹¹ to the moveable or
telescopic sides ₁₁ of the outer nail troughs. As the sides of each trough
are independent the one of the other the nozzle can be inclined as desired and as
indicated by dotted lines in Figure 5.
By the movement of the outer troughs rr around their pivots o' their lower ends
can be set to any desired distance from the centre guide trough to suit the positions
of the bars ii.
The nozzle of the central nail guide is more simply arranged; its sides are slotted
and receive studs projecting from the sides of the nail trough; in this case the sides
of the trough are not telescopic. t is an adjustable plate, it is adjustable up and down
on the back plate o of the foundation frame to which it is clamped by means of the
screws t t.
When the apparatus is at work the plate is set so that its lower edge is at a
distance from the lips of the nozzles s, somewhat exceeding the length of the
nail so that just as the point of the nail falling down the guide trough reaches
the lip of the nozzle, the plate t permits the head of the nail to escape from
the guide trough. The plate t has hinged to it another plate or flap u; at the
time when the nail descends the guide trough the lower edge of this flap u rests
upon the bars ii and the heads of the nails in dropping out of the guide troughs
are received upon the flap and this breaks their fall into the grooves ¹¹. The

page_text: nozzles s 8 are set as is seen in figure 2 so that their. lips enter the grooves 1
and the driving bar as it advances lifts both the flap u and also the nozzles s s
out of the way.
.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is:
.
1. The combination substantially as described with a box nailing machine of an
attachment carrying nail guides which are adjustable as herein set forth to suit the
positions in which it is desired to plant the nails as herein set forth.
2. A pivoted nail guide with telescopic sides and jointed nozzle substantially as
described.
3. A nail guide. adjustable to work with nails of various sizes and having a moveable
plate t and lip which can be set to a distance apart corresponding to the length of
the nail substantially as described.
4. A nail guide substantially as described having a jointed flap u receiving the head
of the nail as it falls into the nail grooves and.so arranged that it rises out of the way
to permit the driving plate to advance.
5. The nail guide attachment and nail guides substantially as described and
represented by the annexed drawings.
