JAMES HAWLEY, CHARLES Cooper, JAMES LEE Derby Works Carruthers
Street Liverpool Engineers do hereby declare the nature of this invention to be as
follows:-
H.
Our invention relates to a class of machinery for making, or nailing together in
various forms, wood boxes, and packing cases, and our object is to do away with the
costly parts of the present box nailing machines, now in use, such as, the hand fed
revolving cylinder machine, the hand fed travelling chain machine, and the automatic
magnet nail fed machine, and other expensive gears, for regulating the supply of
nails to the machines.
In the apparatus we employ, should a faulty nail pass down the grooves from
the corrugated receptacle for nails, no damage is caused to the machine. These
corrugations are somewhat serpentine in shape, having grooves, or slots, at the
bottom of the corrugations, at the back of the receptacle, and the highest of the
corrugations on the front of the receptacle.
We agitate this receptacle by means of a crank, cam, or lever, which is under
the control of the operator. The nails fall into grooves, or slots, and pass on to
suitable adjustable inclined bars, and are received at the bottom of the bars into
dises, having suitable openings round the outer edges, to receive one nail only.
These discs are moved a portion of a revolution, or diameter, by means of mitre, or
bevil gears from the crosshead which carries the hammers for driving each nail,
thus ensuring one with each motion of the machine, which drops into a suitable
hopper and passes down a tube, which conducts the nails into the nail boxes, fitted
with circular shaped dies, which we can work in a vertical, angular or horizontal
position. The nail boxes we construct in three or four pieces in each case using
circular dies, with suitable collars, or projections for supporting same, and holding
the nails firmly during the operation of driving.
At each four, or five operations, of the machine, we register the number of boxes
or cases made, by an ordinary arrangement attached to the crosshead, or driving bar
of the machine.
:
We would have it understood, that the above machine can be worked vertically,
or on the angle, or horizontally, or modified in its general construction without
departure from the essential features of this invention.

COMPLETE SPECIFICATION.
Improvements in Automatically-fed Nailing Machines.
We, JAMES HAWLEY, CHARLES COOPER and JAMES LEE all of Derby Works,
Carruthers Street, Liverpool in the County of Lancaster 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 automatically féd box nailing machines and has for its

page_text: :
principal object improvements in the manner of delivering the nails after passing
from the feed box to a series of hoppers whence they are conveyed to the chucks.
and driven into the boxes by drivers or hammers.
The invention will be best understood by referring to the accompanying drawings,
in which,
Figure is a side elevation partly in section of a portion of a box nailing machine
showing our invention;
Figure 2, a front view thereof; and
Figure 3an enlarged plan view of a portion of the same.
In these,
or
Arisuthe ordinary rocking nail feed box and B the inclined guide bars on channels
along which the nails travel after leaving the feed box. Care discs having an
intermittent rotary motion located one at the bottom of each inclined channel B,
the, number of such bars and discs corresponding with the number of nails to be
driven into the box simultaneously. These discs have suitable recesses
openings D in their outer edges to receive one nail at a time from the inclined
channels B. E is a shaft on which is mounted bevel wheels F and these latter
gear with wheels G mounted on the same spindle as the aforementioned discs C.
H is a ratchet wheel mounted on the spindle E and operated preferably from the
crosshead which carries the hammer for driving each nail, whereby an intermittent,
rotary motion is imparted to the spindle and to the discs C, and the feeding of
one nail from each channel at each stroke of the hammer is ensured.
I is a
hopper connected with a tube or series of tubes J, which hopper receives the
nails from the discs C and passes them down to circular chucks K which are
fitted into the nail boxes L. M are indiarubber bands encircling the chucks K.
N.in Figure 3 represents a nail falling into the hopper I.
The mode of action is as follows:
Supposing the nails to be travelling down each of the inclined guide grooves B
from the feed box and the dises C be rotating, their further progress is stopped by
the said discs until one of the recesses or openings D in such discs comes opposite
the grooves B. One nail from each groove and no more will then drop into each
recess, this being made possible owing to the step by step rotation given to the discs
by the ratchet wheel and pawl device, the discs acting as stops to the advance of
the other nails. The discs continuing their rotation take with them the nail from
each channel B and deposit them in the hoppers 1 as shown in Figure 3; another
recess comes opposite the channels and takes away another nail from each, and so
op, until the machine is either stopped or the nails are all used up. The connection
between the crosshead before referred to or other moving part of the machine and
the ratchet wheel H instead of being a rigid lever or rod may be a yielding or elastic
substance such as a spring or an indiarubber band, so that if a nail should get
jammed.in passing from the inclined bars to the discs the connection will yield and
the other parts of the machine will not be effected thereby. The nails after passing
down the tubes J are held in the required position by the chucks K during the
operation of driving by the hammer O in the usual manner. It must be distinctly
understood that this invention is not confined to the exact details herein set forth
as these may take other forms, for instance, other well known methods of inter-
mittently rotating the discs may be employed, or instead of a disc having an
intermittent rotary motion, a sector or arm having one recess or opening and having
a reciprocatory circular movement about its pivot may be employed.
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. In box nailing machines, the arrangement for delivering or regulating the
supply of nails to the hammers or drivers, which consists in providing in combination
with each inclined feed channel a disc, arm, sector or their equivalents having one
ior.more circumferential grooves or recesses adapted to receive one nail at a time

page_text: from the feed channels, said discs, arms, sectors or their equivalents having an
intermittent rotary movement imparted to them and located in such a position that
they shall act as stops to the advance of the nails, until in the course of their
rotation a recess or opening comes opposite the inclined feed channel aforesaid,
when one nail and no more will drop into each recess and be carried by the rotation
of the disc to a hopper for delivery to the hammers, substantially as described.
2. In box nailing machines, the improved mechanism arranged substantially as
set forth, whereby the supply of nails from the feed box is so regulated and con-
trolled, that one nail only at certain intervals is allowed to pass to each chuck or
other equivalent device.
