WILLIAM B. BRADY, OF AUSTIN, TEXAS.
NAILING-MACHINE.
SPECIFICATION forming part of Letters Patent No. 597,097, dated January 11, 1898.
Application filed September 12, 1896, Serial No. 605,599. 'No model)To all whom it mnay concern;
Be it known that I, WILLIAM B. BRADY, a
citizen of the United States, residing at Aus-
tin, in the county of Travis and State of Texas,
5 have invented certain new and useful Im-
provements in Nailing - Machines, of which
the following is a specification, reference be-
in had therein to the accompanying draw-
ings.
to My invention relates to machinery for driv-
ing nails, and is adapted to automatically dis-
tribute and feed the nails to a predetermined
point, where they are driven into the fabric
to be nailed and, if so desired, clenched.
15 Before defining in the claims the matter I
desire to protect by Letters Patent I will first
fully describe the mechanical parts and the
working thereof with the aid of the accompa-
nying drawings, in which-
20 Figure 1 is a front elevation of the machine,
showing the correlation of the various parts.
Fig. 2 is a complete vertical section thereof
upon the line 2 2. Fig. 3 is a detail face view
of the nail feeding and driving device, the
25 front plate being removed. Fig. 4 is a plan
view of the nail-distributing device. Fig. 5
is a vertical section thereof. Figs. 6 and 7
are details. Fig. 8 is a detail perspective of
the upper end of the nail feeding an ddriving
30 device.
In all of the figures the same numeral indi-
cates the same part.
I is an upright metallic standard resting
upon the base 2 and having in its front face
35 the rectangular opening 3, into n hich are
thrust the wings 4 of the bracket 5 till the
projecting flange 6 is seated against the stand-
ard 1, the said wings then being bolted thereto.
Integral to the bracket 5 and projecting
40 vertically therefrom is the hollow stud 7,
within which rests the pintle 8 of the movable
anvil 0, ending in the removable horn 10.
Pivoted within the bracket 5 is a lever 11,
bolted to the upper face of which is a strong
45 leaf-spring 12, adapted to support at its free
end the pintle 8. A set-screw 13 in the lever
11 adjusts the tension of the spring 12. At
the end of the lever 11 is pivotally secured
the rod 14, traversing the well 15 of the stand-
So ard 1 and secured by screw-threads into the
sleeve 16 of the eccentric - ring 17, within
which rotates the eccentric 18, secured to the
shaft 19, journaled in the pedestals 20, se-cured to the top of the standard 1. The shaft
10 is actuated by the sprocket-wheel 21, se- 55
cured thereto, and engaged by a chain 22 to
the sprocket-wheel 23, secured to counter-
shaft 24, having power-pulley 25.
Depending from the top of the standard 1
and located above the horn 10 is a support- 6o
ing-plate 26,to which is bolted the mechanism
for feeding and driving the nails. Thisnlech-
anism is contained within a shell comprising
the registering half portions 27 and 28, the
former of which is secured to the plate 20, as 65
already indicated. In both the parts 27 and
28 is the vertical groove 20, in which is adapted
to reciprocate the driving-bar :30, having at
one end the punch or die 31 and journaled at
its other end to the link 32, pivoted to the 70
wrist-pin 33 of the wrist-wheel 34, secured to
the shaft 10. Entering the groove 20, near
its lo wer end, is the slantin g channel 35 of the
arms 36, integral with the half portions 27 and
28. This groove 35is adapted to receive nails 75
from a distributing mechanism and to Ceed
the same beneath the die 31. A bead or beads
37 engage the nails just below the head and
preserve them in a proper upright position.
In the side of the portion 28 is a sight-slot 38, So
by which the interior may be viewed.
Pivotally secured in the slot 30 of the por-
tion 27 are levers 40 and 41, having at their
lower ends the fingers 42, which by their suc-
cessive movement separate nail from nail as 85
they slide down the channel 35 and pass the
sime to the proper position beneath the die
31. The said levers are actuated by a fric-
tion-wheel 43 of the lug 43' of the bar 30 com-
ing into contact with the said levers and ac- 90
tuating the spring 43b, retracting the same.
The recess 44, also in said bar 30, permits the
retraction of the lever 41 that its finger 42
may support the column of nails while the
separating is taking place. 95
At the bottom of the groove 20 is located
the sectional jaws 45, the groove through
which contracts rapidly at the mouth 46, at
which point it approximates the size of the
nail-body. The jaws 45 are secured in place 1oo
by a strap-spring 47, secured in the recess 48
of the portions 27 and 28. Thus when in op-
eration the die will thrust the nail through
the jaws, spreading them when the head
passes through. In this manner the tendency 105
of the nail to buckle is avoided.
