I, EDWIN HUDSON BISSETT, of Winnipeg, in the Province of Manitoba, in the
Dominion of Canada, Merchant, do hereby declare the nature of my Invention for
IMPROVEMENTS IN NAIL-CUTTING MACHINES, and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement:
"
My Invention consists of a machine having a rotary head provided with
peripheral cutters, to cut a tapering nail, head and point alternately, an oscillating
feed table, to present the diagonally cut edge of the nail plate parallel to the face
of the rotary head at each succeeding cut, a chute having two passages for
conveying the headless nails, a pair of rotary diske having peripherally a series
of nail holders to receive a nail from each chute alternately, and trip hammers to
head the nail during the passage of the nail holder against a fixed cam, the nail
subsequently falling through an opening in the bed under the holder, all as
hereinafter more particularly described and claimed.
Fig. 1 is a top view of my improved machine.
Fig. 2 is a side elevation of the same.
Fig. 8 is an end elevation, and
Fig. 4 a plan of the bottom of the machine inverted.
•
1, is the main frame of the machine. 2, is a circular head keyed on a shaft 3,
journalled in bearings on frame 1, and said shaft is provided with a fly wheel 4,
belt pulley 5 for rotating the head by belt 6, and driven by shaft 7, or other
suitable means. The rotary head 2, is provided with horizontal cutters 8, in its
periphery, to cut a nail, head and point alternately, from a nail plate fed to the
cutters. 9, is a feed table inclining downwardly towards the rotary head 2, and
on which table the nail plate is placed. One end of said table 9, is pivoted to
a cross bar 10 of frame 1, immediately in front of the rotary head, and plate 9, is
oscillated laterally by a vertical bar 11, pivoted at 12 to frame 1, and one end of
said bar 11, connects with feed table 9, and the other end engages with a wave
wheel 13, on driving shaft 7, so that without over turning the nail plate, a nail
will be cut therefrom head and point alternately by each successive cutter, and by
the oscillation of the feed table the diagonally cut edge of the nail plate will be
bought square to the face of the rotary head, whereby a nail will be cut of the
full width of the plate.

page_text: 14, is a chute having at top inwardly converging sides into which the nail falls
point downwardly on being cut, and the headless nails severally strike against
opposite sides of the chute alternately, and are directed by the inclined sides to
slide down passages 15, in the chute, alternately.
16, are two intermittently revolving disks, provided with radially sliding
blocks 17, the lower ends setting in a cam groove in a bed piece 19, whereby the
blocks will recede, to receive a nail in passing across the foot of passages 15, and
again close by contact with a cam 18, to hold the nail firmly while being headed.
20, are two trip hammers tilting on a bar 21, and operated by wipers 22, on
shaft 7, to strike a blow on the end of the nail protruding above blocks 17, to
make a head on the nail when passing under the hammer.
23, is a ratchet wheel on the spindle of disks 16, and 24 are pawls engaging
with the ratchet wheels, which pawls are connected by a bar 25, pivoted thereto.
33, is a bar pivoted to bed 19 and bar 25, and said bar 33 is vibrated by a
pitman 26, connected by a wrist pin to a wheel 27, on a shaft 28, which is geared
to a shaft 29, by bevelled cog wheels 80, and said shaft 29, is driven by pulley 31,
and belt 6 passing over a pulley 32 on main shaft 7 and pulley 5, whereby both
ratchet wheels will intermittently and alternately turn disks 16, and rest when
the hammer is descending to head the nail,
The nails after being headed fall from the disks 16 through an aperture in the
bed piece into a receptacle below.
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
1. In a nail-cutting machine, the combination, of the rotary cutter head 8, the
vibrating feed table 9, chute 14 having passages 15, disks 16, having radially
sliding blocks 17, trip hammers 20, and means for intermittently rotating the
disks, as set forth, for the purpose described.
2. In a nail-cutting machine, the combination, of the rotary cutter head 8, and
vibrating feed table 9, as set forth.
3. In a nail cutting machine, the combination, of the rotary disks 16, having
radially sliding blocks 17, to receive and grip the beadless nails, and hammers 20,
to head the nails, as set forth.
