COMPLETE SPECIFICATION.
A New or Improved Nailing Machine for Boots and Shoes.
ALBERT ALEXANDER STONE of Ashton Gate Colliery, Bedminster, in the
County of Somerset, Fitter and Turner 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:-
My invention relates to a new or improved machine for nailing on the soles of
boots and shoes, and has for its objects to provide a machine that shall effect its
purpose more automatically and with less attention than such machines as hitherto
inade and used.
In order that my said invention and the manner of its operation may be
fully understood reference is hereinafter made to the accompanying drawings, of
which
Figs. 1 and 2 Sheet 1 are side and front elevations respectively of the said
machine.
Fig. 3 Sheet 2 is a plan view of the nail box and its accompanying groove
or track down which the nails are automatically fed to the nailing plunger
or ram.
Fig. 4 is a vertical section of Fig. 3 taken upon the line A. B.
My invention consists of a suitably shaped metallic frame or standard A,
adapted to carry in guides a and a' a vertical plunger B.having at its lower end a
ram C, shaped to fit upon or cover the heads of the nails to be driven. The said
plunger and ram receive vertical motion by the means of a link D, connected to a
crank or disc E, mounted upon a horizontal shaft F carried in suitable bearings b
and provided by the frame or standard A, and upon which is mounted loosely a
pinion or toothed wheel G, in gear with a spur wheel H, carried upon a stude
borne by the frame or standard A, and receiving motion from any convenient or
available power, or driven by hand. The shaft F carries a sliding.chuck J,
operated by a lever K, which when lowered causes a pin d upon J to engage with
a recess e in the wheel G (Fig. 1) and by this means rotary motion is imparted to
the shaft F, and an up and down motion to the plunger and ram B C once to
each revolution of F, but when the lever K is raised as at Fig. 1 the chuck J is
withdrawn from its connection with the wheel G, and a pin or projection f upon
the opposite side of J engages with a recess g in the frame A and so locks the
shaft with B and C in their highest positions.
The frame or standard A carries a nail box L, preferably at or about the angle
shewn in Fig. 1, the top of which may be entirely open as at Fig. 2, or partly
closed as shewn by the sectional view Fig. 4, an opening being left at h for the
insertion of the naile to be used, which then.fall upon a partial diaphragm ; and
from this through an opening at on to the bottom of the box, in which is formed
two or more (preferably four) approximately semicircular grooves or slots 1, of
such size as to permit the points or shanks of the nails in use to pass therethrough,.
while the heads of these rest upon the upper surface of the said slots or grooves.
In the centre of the said box is a vertical spindle m, which passes down through
the bottom and carries a crank n, to which is connected one end of a link o, the
opposite end of which is pivotally connected to a spring M fixed upon the frame or
standard A in such a position that swellings or extensions p fixed upon or formed
integrally with the wheel H may collide therewith, and by deflecting the spring M,
impart a partial rotary motion to the spindle m. Upon the spindle m is fixed two

page_text: or more brushes N (preferably three) the bristles of which serve to sweep the
nails along the said grooves until their points drop thereinto, and when in this
position the said brushes push the said nails out of the said grooves or slots
through an opening in the side of the box I, covered by a plate s having openings t
coinciding with the said slots, the said plate s being interchangable according to
the size of nails in use, and adjustable by the means of fly nuts t¹, and such nails
only as are point downwards are by the agency of the brushes. Nr pushed through
the openings in s-(as at Fig. 1) into the groove O of a guide plate or chute P
attached to the box L, at such an angle, that by the vibration of the machine the
said nails are passed along the groove O in single file as shewn at Fig. 1. The
lower end of the plate or chute P terminates immediately below the rain C, und is
thereat provided with a pair of jaws & and 3, kept closed by the tension of suitable
springs and to, the said jaws being so formed internally as to receive the foremost
nail of the row passing down the groove 0.
The boot or shoe the sole of which is to be nailed, is mounted upon an iron
last R forming the upper end of a curved arm R', pivotally mounted at R' upon
a sliding plate S, mounted upon the frame or standard A, and provided with a
suitable spring v, the tension of which operates to draw the arm R' in the direction
of the arrow Fig. 1, and the boot or shoe upon R beneath the jaws and s. Upon
the frame or standard A is mounted a sliding plate T, the position of which is
adjustable by the means of n slot to and nut o. The said plate T carries at its free
end a rotary roller T', against which the sole of, the boot or shoe abuts when in
position upon R and beneath the jaws s¹ and s, the adjustment of the plate T
serving to regulate the distance from the edge of the sole at which the row or rows
of nails are to be inserted.
The shaft F carries an eccentric V the rod of which V' is adjustably connected
to a slotted plate V, carrying a pawl V³, which engages with the teeth of a
ratchet wheel V, fixed upon a shaft W, pivotally mounted at a point Win a
suitable carrier W, and upon the free end of W is mounted a wheel W³, having
any desired number of sharp pointed teeth which engage with the upper surface
of the sole of the boot or shoe when in position for nailing. (This wheel is
hidden from view in Fig. 1 but is shown in Fig. 2.) The frame or standard A
carries a vertical rod X, the lower end of which is so formed as to rest upon the
free end of the shaft W, and is provided with a spring X', the tension of which
- serves to press the wheel Wa upon the sole of the boot or shoe, and as the ratchet
wheel Vis rotated the distance of one tooth at each revolution of the shaft F, it
follows that a corresponding rate of rotation would be imparted to the shaft W and
the wheel W, the teeth of the wheel V being so adjusted that the rotation of the
wheel W would at each movement push the boot or shoe round a distance equal
to the desired distance between the nails, and when the boot or shoe is being
placed in position upon R or being removed therefrom, the rod X may be raised
by a lever Y, and by the removal of this from contact with the shaft W the said
shaft would be automatically raised by the tension of a spring Y¹, and so lift the
wheel Ws out of contact with the sole of the boot or shoe.
From the foregoing description of my invention it will be understood that the
plunger B would be lowered once to every revolution of the shaft F, and given
that the boot or shoe is in position upon R beneath the jaws the lowering
of B and consequently the ram C, the latter by engaging with the head of the
nail within the jaws as shewn in Fig. 1, would force the said nail downward
into the sole of the boot or shoe, the jawa s readily parting to permit the
passage of C, aud at the return or up motion of C the jawe s s would again
close and receive the next or following nail ready for the next downward travel
of C, and during the upward travel of C, the wheel W would remove the sole
the desired distance before the next nail was driven thereinto, and so on ad lib.
Should a second row of nails be needed in the boot or shoe the plate T would be
adjusted to permit the sole to come farther under the jaws a distance equal
to that desired between the first and second rows.
