PROVISIONAL SPECIFICATION.
Improvements in Tacking or Nailing Machines.
I, FREDERICK CUTLAN, Engineer, of Castle Hill, Wellingborough, in the
County of Northampton, do hereby declare the nature of this invention to be as
follows:-
This invention relates to machines, whether hand or power, for driving tacks
nails and the like, chiefly for use in the manufacture of boots and shoes; I will..
describe it as applied to the well known Cutlan hand nailers.
In the nailer, the lower end is a substantially cylindrical channel, down which
the tack is forced by a reciprocating plunger, aud the object of my present
improvement is to provide means for holding the tacks pending the forward move-
ment of the plunger to drive the tack. Hitherto I have done this in various ways,
one of which is described in my previous Patent No. 220 of 1890 in which the
tack is held between a pair of spring jaws. This arrangement I have now-
simplified, and dispensed with the before mentioned spring jaws, using instead an
internal spring tongue, the nipping point or jaw of which may be hollowed or
recessed to accommodate the tack. I do not bind myself to one way only of
securing this spring tongue, but I have obtained satisfactory results by placing a
metal clip or plate across the instrument, recessed to form a portion of the channel"
down which the tacks and plunger pass, and fitting in a groove in the end of the
instrument, and fixed by a single screw. The end of the spring tongue is
flattened to fit between this plate and the wall of the instrument and is so gripped
and held.
I find that this single spring tongue while simpler and cheaper than the previous
arrangement is quite efficient.

I, FREDERICK CUTLAN Engineer, of Castle Hill, Wellingborough, in the
County of Northampton, 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:-

improvement is to provide means for holding the tacks pending the forward move-
ment of the plunger to drive the tack. Hitherto I have done this in various ways,
one of which is described in my previous Patent No. 220 of 1890 in which the
tack is held between a pair of spring jaws. This arrangement I have now
simplified, and dispensed with the before mentioned spring jaws, using instead an
internal spring tongue, the nipping point or jaw of which may be hollowed or
recessed to accommodate the tack. I do not bind myself to one way only of
securing this spring tongue, but I have obtained satisfactory results by placing a
metal clip or plate across the instrument, recessed to form a portion of the channel
down which the tacks and plunger pass, and fitting in a groove in the end of the
instrument, and fixed by a single screw. The end of the spring is flattened to fit
between this plate and the wall of the instrument and is so gripped and held.
I find that this single spring tongue while simpler and cheaper than the previous
arrangement is quite efficient.
In the accompanying drawings which illustrate by way of example one con-
struction according to this invention,
Figure 1 is an elevation of one half A of the tapered nozzle constituting the
lower end of a Cutlan hand-nailer;.
Figure 2 is a view at right angles to Figure 1, and partly in section, showing
this half A in place in the railer in contact with the companion half B to which
it is secured by means not shown in the drawing.
C is the cylindrical channel before referred to, half of the channel being formed
in the part B and half in the part A and plate G hereinafter referred to. D is
the lower end of a plunger which reciprocates in the channel and acts upou
tacks which come singly into that channel down the groove E, and are caught and
stopped by the nipping point or jaw F1 of the spring F, which protrudes into the
channel as shown, being slightly dished. It will be seen from Figure 2 that the
spring F is held between a plate G and the adjacent surface of a recess A' in
the part A; the plate G is T-shaped, see Figure 1, the head of the T fitting a
groove formed in the part A and the stem (lettered G¹) extending down the
groove C so as to cover all the lower portion of the spring F except the tip F.
His a single screw which passes through the plate G into the part A, and serves
to secure the former in position. J (Fig. 2) shows a tack caught by the spring F
and in readiness to be forced out of the end of the nozzle upon the next descent
of the plunger.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is
1. In tacking or nailing machines or the like a plain or recessed or dished
spring arranged and operating substantially as and for the purpose specified.
2. In tacking or nailing machines or the like the combination with a removable
section A of a spring tongue arranged and operating substantially as and for the
purpose specified.
3. In tacking or nailing machines or the like the combination of a spring
tongue F, and a plate such as G substantially as and for the purpose specified.
Dated this 22nd day of December 1896.
