and Shoes.
I, FREDERICK CUTLAN, of Castle Hill, Wellingboro', 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 which relates to hand-operated nailing machines for boots and shoes
will be best understood by reference to the accompanying drawings in which fig. 1 is
a side elevation of the complete machine with the plunger represented in dotted lines
in its normal position and in full lines in its depressed position; fig. 2 is a front
elevation with the nail guide and other parts removed; fig. 3 is a section on the
line ab of fig. 2 of a portion of the same; fig. 4 is a transverse section of the nail
reservoir on the line c-d of fig. 1; fig. 5 is a view of the selector plate G ; fig. 6 is
a view looking from the top of the machine of the block F and plate H and selector
plate G working between them; fig. 7 is an elevation of the plate J and fig. 8 is an
elevation showing the plate J attached to the plate H. Figs. 9 and 10 are respectively
a side and an end elevation of the apparatus by which the nails are charged into the
nailing machine.
Like letters indicate like parts throughout the drawings.
Referring to figs. 1, 2 and 3 A is the stock which at its upper part as shown in fig. 3
may be bored out at A¹ to receive the plunger B which is capable of being moved
longitudinally in the guide thus constituted. The lower end of the stock A terminates
in the portion A2 and to this is secured by screws A³ a cover plate A* corresponding
to the portion A³ which together form complete guides for the nail driver Bi
and for the delivery of the nails to the effective end of the driver. Each of these
parts A2 and A is formed with half passages which together form the complete
passages A and A. The nail driver B₁ may be fixed in any convenient manner in or
to the lower end of the plunger B on the upper end of which is provided the head B2
between which and the upper end of the plunger guide A¹ the spring B³ exerts its
pressure so as to tend always to move the plunger B into its normal position in
which it is shown in fig. 2. The plunger guide A is slotted at A' to admit of there
being longitudinally reciprocated therein the projection B which may be secured to
the plunger B in any desired manner say by means of the screw B but which slot A7
and stud B prevent the plunger from being rotated in the guide A¹. The
passage A is provided with a hinged lid or door A³ which is normally kept closed by
an eccentric headed screw A° or other suitable means and which may be opened as
shown in dotted lines in fig. 1 should it be desired to have access to the said
passage A. This passage A inclines towards and joins the passage A' at a part just
in front of the normal position of the end of the nail driver B₁, and near the extreme
lower end of the passage A are provided the jaws C which pass through the
parts A2 and A* and are fixed to springs (which are secured to the said parts A²
and A in any convenient manner. These jaws C when in their normal position
project inside the passage A sufficient to prevent a nail by its own weight falling
between them, but when the nail driver B₁ is pressed onto the nail it forces them to
move apart and after the withdrawal of the said driver the springs C¹ immediately
return them to their normal position.
D is a plate pivotted at D¹ fig. 2 to the stock A and provided with a curved or inclined
cam slot D2 and with a projection D³. B is a block or, it may be an anti-friction
roller pivotted on the beforementioned stud or projection B and which engages with
the cam slot D² so that when the plunger is fully depressed it will be moved to the
position indicated by dotted lines in fig. 2.

page_text: E is the nail reservoir which may be formed in part with a handle E¹ by which the
apparatus. may be held and which reservoir is secured to the stock A by the plate E
by means of screws and if desired a clamp or clip E³. The plate E³ as shown in
figs. 1 and 3 is recessed-to enable the cam plate D to be moved freely between it and
the adjacent part of the stock A. The nail reservoir E has preferably the wall 'E*
attached by screws E³ so that it may conveniently be removed if found necessary, and
it is also provided with a pivotted door or cover E' which may be moved aside when
the reservoir is to be filled and moved back again over the groove E7 fig. 4 to prevent
the nails from falling out of the said groove.
F is a block which may be secured to the stock A by means of its lugs F¹ through
which pass the screws F2 only one of which is shown in dotted lines in fig. 1. F³ is a
slot or groove which coincides with the groove E' of the reservoir E and which leads
into the passage F which joins and forms an inclined continuation or rather
commencement of the before mentioned passage A as shown most clearly in fig. 3.
G is a hard steel plate herein termed the selector which is capable of being moved
in the direction of its length in a recess formed in the block F and between such
block and the plate H which is secured to the said block by the screws H¹ or equivalent
means. The plate G one side of which is shown in figs. 2 and 5 and the reverse side in
fig. 6 is formed with an opening G'into which as shown in fig. 2 fits the before
mentioned projection D³ of the plate I through which it receives reciprocating motion
from the said plate D. The plate G is also provided with a recess G2 the part g of
which is deeper than the part g¹ to the extent of about the thickness of one of the
nails. G³ is an inclined slot which connects the recess G² with the opening G. The
point g is that by which the nails are caught and passed one by one down to the nail
driver as hereinafter described. The plate Has shown most clearly in fig. 6 is provided
with a slot H' leading to a circular opening H3 both of which respectively coincide
with the slot F³ and passage F¹ in the block F the said plate H as shown in fig. 6 being
also cut away at H to enable the cam plate D at one side of it to freely operate the
selector G at the other side.
J, shown most clearly in figs. 7 and 8 is a plate which is secured to the plate H
so that its tongue J¹ will be opposite the slot H2 and opening H³ but so as to
leave a small space between the said tongue J¹ and edges of the slot H2 in the
plate H sufficient to accommodate the bead of one of the nails. The tongue J' thus
serves as a continuation of the back of the enlarged portion E8 of the slot E' and
provides for any adjustment which may be necessary in this part of the machine
to secure the proper progress past it of the nails.

Referring to figs. 9 and 10 K is a standard to the upper inclined part of which are
secured plates between the opposing edges of which a space is left so as to form
an inclined shoot k¹ for the nails which in figs. 9 and 10 are marked Y.
plates which prevent the passage down the shoot k¹ of nails having heads larger
than it is desired to use or larger than can pass freely through the before described
nailing machine, but these plates or gauges k² may be adjusted nearer to or farther
from each other. 3 is a latch pivoted to one of the plates k and provided with
a handle for enabling it to be readily moved across or away from the shoot k¹
and thus retain the nails in or allow them to slide from the said shoot.
L is a nail reservoir pivoted at L' to the upper portion of the standard K or
other convenient part. L² is a hinged lid or cover which may be kept closed
over the reservoir L by the screwed knob L³; after unscrewing this knob the
lid 12 may be raised as shown in fig. 9 and the reservoir L can then be filled with nails.
The bottom of the reservoir as shown in dotted lines in figure.10 is formed by two
inclined plates L* the lower edges of which are at such a distance apart as will leave.
between them a slit of sufficient width to allow the shanks but not the heads of the
nails to fall through so that the nails will be suspended points downwards in the
manner shown in fig. 9 and will slide from the reservoir down into the shoot k¹
with which the outlet from the reservoir coincides. L' is an arm secured to the
reservoir L and to which is pivoted the upper end of the link or rod L* the said
.J

page_text: arm L' being provided with two or more screw-threaded holes L' which admit of the
point of connection of the link Le with the arm L being adjusted for the purpose of
regulating the position of the reservoir L.

M is a shaft supported in the standard K or other desired part and having secured
on one end a fly wheel M¹ and on its other end a crank handle "M", it also has
secured on it a toothed pinion M³. N is a shaft supported in the standard K or in
other convenient manner and upon which is mounted the wheel N which gears with
the pinion M³ and which wheel N carries a crank pin N³ on which is pivoted the
lower end of the before-mentioned link L®.

It will be seen that when the shaft M is rotated by means of the handle. M' the
wheel N will be rotated through the pinion M³ and the reservoir L will be oscillated
as indicated in dotted lines in figure 9. The nails in the reservoir L will thus be in
constant agitation and will be made to assume their correct position as in figure 9
and pass down the shoot k¹ as far as the latch k³ which for the time being will arrest
their further progress. As soon as the shoot is sufficiently full of nails and it
desired to charge them into the before described nailing machine the cover E of the
said machine is turned aside from the reservoir E whose upper end, ie, then placed
against the outlet of the charging apparatus figures 9 and 10 i.e. the lower end of
the shoot suitable means being preferably provided for ensuring that the nailing
machine shall be applied in the correct position for receiving the nails. The latch
is then turned aside from the shoot k¹ and the nails will leave the charging appliance
and slide down the groove E' so that their heads pass down the part E of the
groove E the groove E' itself accommodating the shanks of the nails. The heads of
the lowest of these nails will pass between the tongue J' and plate H but the lowest
one only as shown in figure 3 will be supported on g₁ which prevents it from falling
directly through the machine. The operator then presses down, the plunger to its
lowest position as shown in figure 1 and thereby through the block B working in
the cam slot D2 of the plate D and by means of the projection D³ of the said plate
the selector G will be moved to the left of fig. 2 and the point g² will be thus moved
past the lowest nail which will then be supported on g. The operator then releases
the head B2 and the spring B³ will raise the plunger to its normal position as shown
in fig. 2 and in so doing, through the cain plate D will move the selector G towards
the right in fig. 2 and the point 92 which is only high enough above the level of g to
reach above one nail will draw the lowest nail into the inclined. slot which in the
further movement of the selector will draw the said nail down the slot H2 (which
like G³ is not large enough to allow the head to pass through) until it reaches the
opening H³. At this time the opening G coincides with the opening Hand
passage F so that the head of the nail is thereby released from the edges of the
slot H2 in the plate H and the said nail will fall down F and A° into the lower part
of A' where its shank will fall between the jaws C but they will support it by its
head as shown at X in fig. 3 until it is forced on and between them by the nail
driver B¹. This initial non-nailing, operation is only necessary to prepare the
machine for use when the supply of nails had been previously exhausted or when
used for the first time.
When with the machine thus prepared it is desired to drive nails into a boot or
shoe the extreme end of A' A' is pressed upon the desired part and the plunger B*
forced down by the hand of the operator so that the driver B' will force the nail X
then supported in the jaws C between the said jaws and into the hoot while during
the descent of the plunger B the selector G will have been moved to the left in
fig. 2 and when the said plunger is next moved up it will be moved to the right and
this as before described brings down another nail. The nailing may thus be continued
without intermission until the charge of nails in the reservoir E is exhausted a
single nail being driven at each depression of the plunger B and a single nail being
selected and removed from the others of the charge at each complete stroke that is to
say descent and ascent of the plunger.
