PROVISIONAL SPECIFICATION.
Improvements in or relating to Hand-operated Nailing Machines,
commonly known as Tackers.
1, FREDERICK CUTLAN, of Castle Hill, Wellingborough, in the County of
Northampton, Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to hand-nailing machines or tackers by which the uppers
of boots and shoes are tacked to the inner sole during the process known as
lasting. The invention relates to a device for gripping and pulling the edge of
the leather or other material, usually the upper, over the last, whereby the
grippers usually used in lasting machines or the hand pincers may be dispensed
with, particularly for light work. The invention may be in the form of an
attachment which may be applied to various forms of tackers, or it may form a
portion of the tacker itself.
The gripping device consists principally of a suitable bracket, frame or the like
which I prefer to make detachable from the rest of the tacker and to connect it
by a wing headed set screw or the like so that it may be easily detached and
replaced; nevertheless, as above stated the attachment may be a fixture upon the
tacker. The new device consists of a preferably spring-controlled gripping jaw
which may have one or more V-grooves or roughenings which if necessary engage
with corresponding parts upon the Fracket portion so arranged that when the
tacker is employed the edge of the upper is gripped between the movable and
fixed jaws and the upper can then be strained upon the last by pressure upon the
tacker, and the tack driven without the necessity of employing either a hand or
mechanical straining device. For light work this is a very important feature.
It will be understood that the details may be greatly varied without departing
from the spirit of this invention and so long as a gripping device or attachment is
used in connection with the nailer it would come within the scope of this
Specification.

Improvements in or relating to Hand-operated Nailing Machines,
commonly known as Tackers.
I, FREDERICK CUTLAN, of Castle Hill, Wellingborough, in the County of
Northampton, Engineer, 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 band-nailing machines or tackers by which the uppers
of boots and shoes are tacked to the inner sole during the process known as lasting.

page_text: The invention relates to a device for gripping and pulling the edge of the leather
or other material, usually the upper, over the last, whereby the grippers usually
used in lasting machines, or the hand pincers may be dispensed with, particularly
for light work. The invention may be in the form of an attachment which may
be applied to various forms of tackers, or it may form a portion of the tacker
itself.
The invention will be best understood by reference to the accompanying
drawings in which
Figure 1 is a side view of the invention as applied to a tacker,
Figure 2 being a plan of the new gripping jaw, and
Figure 3 an underneath view of the bottom of the tacker.
Like letters represent like parts throughout the drawings.
A represents diagrammatically any ordinary form of hand nailing machine or
tacker, preferably such as is set forth in the Specification to Letters Patent
originally granted to me No. 220, dated 6th of January 1890. B is the operative
end or nose of the tacker, the working face or end of which may be roughened a
shown in Figure 3. The tacker A is provided with a bracket or extension (
which may be detachably connected with it or it may be permanently attached,
forming part of the instrument. D is a gripping jaw normally retained in the
open position shown in Figure 1 by the compressed helical spring E, the stop C'
on the bracket operating in conjunction with the joint F serving to prevent the
jaw from opening too wide. D' is the operative portion or jaw and it will be
observed that the three faces D2 are all bevelled so as to fit the bevels B' of the
tacker B when the jaws are closed by the tacker being forced down on to the
work, turning upon the joint F, and assuming the position shown in dotted lines
in Figure 1. By this means the upper leather of the boot which when the tacker
is applied enters between the jaws B and D is very securely gripped between the
faces B and D2 all of which may be roughened if desired. I do not bind myself
to this particular shape or construction of the jaws as they may be varied at
pleasure, but I find this form to give excellent results.
The hook D³ affords a convenient hold to the operator whereby he can pull the
whole instrument when gripping the upper towards him thus stretching it on to the
last.
In using this instrument it is applied to the last and the projecting edge of the
upper entered between the jaws, then by turning the jaw D upon its pivot F, or
holding that and moving the tacker, the two jaws are brought together, the upper
is firmly gripped between them and by pulling upon the hook D³ the operator
can strain the upper as much as he requires, and then drive the tack with the
tacker in the usual way and proceed to the next tack.
This attachment may be applied to existing tackers of various makes as well as
to new ones, and may in any case be made either a permanent attachment or a
removable one.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, declare that what I
claim is :-
1. The combination with a hand nailing machine or tacker of a gripping jaw or
jaws.
2. The combination with a hand nailing machine or tacker of a fixed or
movable bracket such as C and gripping jaw D pivotted thereto substantially as
and for the purpose described and illustrated in the accompanying drawings.
3. The combination with a baad nailing machine or tacker of a shaped end
such as B' and pivotted jaw such as D D1 D2 for gripping the upper.
4. The combination with a hand nailing machine or tacker of the complete
gr pping and pulling device substantially as described and illustrated in the
accompanying drawings.
5. The combination with a hand nailing machine or tacker of a gripping and

accompanying drawings.
