Improvements in Loose Nailing Machines for Coverings for the Feet.
I, EDWIN LEE, of 17, Church Bank, Bolton, in the County of Lancaster, Boot
and Clog Manufacturer, do hereby declare the nature of this invention to be as
follows:
-
This invention relates chiefly to an improved nail feeding device for nailing
machines for coverings for the feet which is simpler in construction and more
reliable in action than those hitherto known.
To this end I employ the shoots, which convey the nails from the nail box to
the throat of the nailing machine, side by side at one side im lieu of at each side
of the throat and in such a manner that either of them can be brought in and
out of use during the working of the machine at will. The lower ends of the
said shoots are rendered horizontally adjustable so that either of them can be set
in register with a slot formed in the respective side of the throat of the nailing
machine. The nail box, with which the upper ends of the said shoots communi-
cate, I divide into compartments corresponding in number with that of the said
shoots and each of the said compartments I furnish with a slide the upper edge
of which is channelled and in its highest position forms a continuation of the
respective inclined shoot. Each slide is connected to a lever fulcrumed to a
suitable stationary part of the machine and adapted to be raised when required
by means of a projection secured to a suitable moving part of the nailing machine,
say the awl slide, which projection contacts with a slide on the said lever so that
when placed opposite to the said projection the respective lever is rendered
operative and when on one side thereof inoperative.
Each of the said levers is placed under the influence of a spring which tends
to bring the slide in the nail box below the mouth of the inclined shoot, so that
the said slide may fill with nails. When the said lever is lifted by the projection
on the awl slide, the nail slide connected therewith is brought in line with the
respective shoot and the nails are allowed to slide into the same.
In order to cause the nails in the shoots to enter the slot formed in the side
of the throat one by one only, a slide is employed in the said throat which is
moved inwards between the shanks of the first and second nail so as to allow the
first nail to fall into the throat whilst keeping back the others. The upper edge
of the said slide is furnished with a finger adapted to engage underneath the
head of the second nail as the slide moves in and lift the same off the first nail
and thereby liberate the latter.
In the lower end of the presser foot a small spring blade is employed in a
cavity adapted to push the nail off the presser foot and thus ensure it being
driven correctly.
To facilitate the nail taking up its correct position in the throat the latter or
the nail driver may be magnetized so as to attract the nail.
In order to cause the nails not to obstruct the entrance of the shoots a pipe

page_text: is arranged which directs a blast of air against the nails. This blast of air may
be produced by means of a pair of bellows worked at the proper time, say from
a cam on the driving shaft of the machine.
In lieu of magnetizing the throat or nail driver a blast of air may also be
directed against the nail in the side slot of the throat.
In order to facilitate the nailing of clogs I form in one side of the presser foot
a slot through which the welting to be nailed to the sole can be fed and which
serves as a guide for the same.
I also provide a jack specially adapted for holding clogs to be railed. This
jack has a pillar hinged to a bracket and carrying at its upper end a horizontal
stud free to turn therein and projecting on one side. The projecting end of
this stud is formed longitudinally with a slot in which is employed a plate
adapted to slide but. prevented from leaving the said slot by a set screw engaging
in a groove or the like.
The outer side of this plate is formed with a plate at a right angle thereto
furnished near one end and about the middle with stationary fangs and with
movable fangs at the other end, which are under the control of a lever.
This plate and the said fangs are adapted to receive and support the clog to be
operated upon, the same being placed with its sole against the said vertical plate
and secured thereto by thrusting the last named fangs by means of the respective
lever against the outside of the heel, thereby its inside against the fangs in the
middle and the toe end of the clog between the first named fangs simultaneously.

Coverings for the Feet.
I, EDWIN LEE, of 17, Church Bank, Bolton, in the County of Lancaster, Boot
and Clog Manufacturer, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement;-
This invention relates chiefly to an improved nail feeding device for nailing
machines for coverings for the feet which is simpler in construction and more
reliable in action than those hitherto known.
And in order that my invention may be more fully understood I have caused
to be appended hereunto one sheet of drawings marked with letters of reference
indicating like parts in the various figures, Fig. 1 being a front view and Fig. 2
a sectional side view at line A-A Fig. 1, of the head of the nailing machine
showing my improvements applied, and Fig. 3 a vertical section of the nail box
at line B-B Fig. 1, Fig. 4 is a detached sectional front view, Fig. 5 a plan, and
Fig. 6 a sectional side view at an enlarged scale of the shoot in connection with
the nail throat, Fig. 7 a sectional side view at line C-C Fig. 4, and Fig. S a back
view of the shoot adjusting arrangement of the machine. Figs. 9 & 10 are a
detached front view and side view of a modification in the working of the nail
slides. Figs. 11 & 12 are respectively a side view and a plan of the presser foot
at an enlarged scale.
In carrying out my invention and referring to the figures generally, a is the
head, the driving shaft, c the awl slide, d the driver slide, e the throat, and
f, f¹ the nail shoots, g, g' the nail box, and h, the nail lifters or slides.

page_text: Instead of employing a nail shoot at each side of the throat as hitherto, I
employ the same side by side, at one side of the throat e, see more particularly
Fig. & 2, in such a manner, that at will, either of them can be brought in and
out of use during the working of the machine.
The upper end of the said double shoot is attached to and communicates with
the nail box, which is divided into two compartments whilst the lower end
is rendered laterally movable so that either of the shoots can be set in register
with a slot c¹ formed in the respective side of and communicating with the
throat e, of the machine.
This lateral adjustment may for instance be effected by hinging to the back of
the shoots f, f an arm adapted to slide in a stationary projection m which
engages in recesses, formed in the arm 1, corresponding in number and dis-
tance with that of the shoots f, f', whilst a spring a pulls the hinged arm onto
the projection m and thus retains the shoots f, f in the desired position.
Each of the said nail compartments is furnished with a slide h, the upper
elges of which are channelled and in their highest position form a continuation
of the respective channels in the inclined shoots f, fl.
Each slide h, h¹ is connected to a lever o, o fulcrumed to a suitable part of the
machine, say to the bracket p and adapted to lift at suitable intervals nails from
the box g, g in line with the shoots f, f¹ and allow the same to run down the
said shoots as may be required.
The said levers may be actuated from a projection . fixed to a suitable moving
part of the machine, say the awl slide e and adapted to contact with either of the
slides r,
on the said levers, which when placed in line with the said projection
render the respective nail slide operative and in-operative when moved out of
contact therewith.
Each lever o, o is placed under the influence of a spring o" which pulls the
nail slides below the mouth of the shoots f, f¹ in order that they may fill with
nails.
In lieu of rendering one or the other of the said nail slides in-operative, they
may be arranged to move together, for instance as shown in Figs. 9 & 10, by
adapting their lower ends to rest jointly upon a lever under the influence of a
spring which lever is actuated by a cam 2 on the driving shaft b.
In order to cause the nails in the shoots f, f' to enter the slot e¹ formed in the
side of the throat e one by one only, a slide s, see also Figs. 4, 5 & 7, is employed
in the throat e which, before the driving takes place, is moved inwards between
the shanks of the first and second nail so as to allow the first nail to fall into the
throat e whilst keeping back the others. The upper edge of the said slide is
furnished with a finger sl, adapted to engage underneath the head of the second
nail as the slide s moves in and lift the same off the first nail and thereby liberate
the latter.
The said throat slide may be moved in and out, by an incline t on the awl
slide and a spring 2 drawing it in.
In a cavity in the lower end of the throat c see Fig. 4, a small spring
blade may be employed adapted to push the nail off the presser foot and thus
ensure it being driven correctly. In order to cause the nails not to obstruct the
mouth of the nail shoots, a pipe w is arranged which directs a blast of air against
the nails. This blast of air may be produced by a pair of bellows worked at the
proper time, say from a cam on the driving shaft of the machine as will be
readily understood.
A blast of air may also be directed against the nails in the side slot e¹ of the
throat by the pipe el, see Fig. 1, in order to ensure the proper position of the
nail in the throat.
In order to facilitate the nailing of clogs I form in one side of the presser
foot a slot, see more particularly Figs. 11 & 12, through which the welting
to be nailed to the sole is fed thus serving as a guide for the same.
I also provide a jack specially adapted for holding clogs to be nailed, see

page_text: Figs. 1&2. This jack has a pillar a hinged to a bracket y and carrying at its
upper end a horizontal stud free to turn therein and projecting at one side. The
projecting end of the study is formed longitudinally with a slot y2 in which
is employed a plate z adapted to slide but prevented from leaving the said slot
by a set screw engaging in a groove or the like.
The outer side of this plate has another plate at a right angle thereto, fur-
nished near one end and about the middle with stationary fangs, and with
movable fangs at the other end which latter are under the control of a lever 26.
The said fangs are adapted to receive and support the clog to be operated upon,
being placed with its sole against the vertical plate 22 and secured thereto by
thrusting the fangs by means of the lever against the outside of the heel,
thereby the inside of the latter against the fangs in the middle, and the toe
end of the clog between the fangs at the end simultaneously.
It will be readily understood that instead of employing a double shoot only,
any number of shoots or nail races may be arranged side by side and jointly
adjustable at one side of the head of the machine in connection with the slot e
in the throat, without departing from the nature of my invention.
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:-
1st. In loose nailing machines for coverings for the feet, a number of inclined
shoots f. f arranged side by side at one side of the nail throat e, the latter being
formed with a nail slot e¹ opposite the lower end of the said shoots, and the said
shoots rendered laterally adjustable for the purpose of bringing one or the other
of the said shoots into register with the nail slot e¹ in the throat, all substantially
as set forth.
2nd. In combination with the loose nail feeding device specified in the pre-
ceding claim, a nail box g, g₁ divided into compartments each containing a
vertically movable nail slide h, h¹ the said nail box communicating with the
upper ends of the said laterally movable nail shoots f, f¹ and the said nail slides
being adapted to lift nails from the nail box in line with the said shoots, all
substantially as set forth.
3rd. In a loose nailing machine such as specified in the preceding claims, the
throat e, e furnished with a slide s having at its upper edge al fingers, all sub-
stantially as and for the purpose set forth.
4th. In a loose nailing machine such as specified in Claims 1 & 2, the employ-
ment of jets w & w¹ adapted to direct severally or jointly a blast of air against
the mouth of the nail shoots and the slot e' in the throat e, all substantially as
and for the purpose set forth.
5th. In a loose nailing machine for nailing clogs, a jack for holding the clogs,
consisting of a hinged pillar, carrying at its upper end a rotary stud y', in one
end of which is rendered longitudinally adjustable a plate z, 2 furnished with
fangs for clamping the clog to be nailed, all substantially as set forth.
Dated this 20th day of December 1898.
