Improvements in Nailing, Sprigging, and Pegging Machines
Employed in Boot and Shoe Manufacture.
I, RICHARD WILKINSON BATEMAN of 5 Hanover Street, Halifax, in the County
of York, Shoemaker, do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements in nailing, sprigging, and pegging
machines employed in the manufacture of boots and shoes, and consists
Firstly. Of an improved adjustable feed motion for feeding nails, sprigs, or
rivets to the cutting dies, or shear blocks in nailing, sprigging and pegging
machines employed in the manufacture of boots and shoes.
Secondly. To improvements in the method of and means employed for locking
in position the vertical shaft which carries the "horn
or stoop of machines as
aforesaid employed in the manufacture of boots and shoes.
According to this invention the adjustable feed motion is designed to feed, or
supply to the cutting dies, or shear blocks, nails, sprigs, or rivets which have
previously been partly prepared or manufactured by nearly severing the metal bar,
strip, or wire from which they are made. The continuous length of nails, sprigs,
or rivets are passed along a groove or recess, and through a slide piece carried in
a slide bed in the head of the machine. In the slide is a catch or pawl, the point
of the latter entering one of the nicks or recesses between the head of one nail,
and the point of the next succeeding nail, and as the slide is moved forward, a
distance equal to the length of the nail or sprig, the wire or bar is fed forward the
required distance. The slide carrying the pawl is operated by a scroll or wiper
tappet or cam groove acting on a toothed segment arm, the latter in turn acting on
a toothed segment fast on a shaft carried in a bracket fixed to the machine. The
tappet or cam groove gives an oscillating motion to the segment arm and by the
latter to an arm, to which is fixed a link, the upper end of which is attached to
the slide so that an up and down motion is imparted to the latter which slides in
the slide bed formed in the head of the machine, and the continuous nails are
thereby fed to the shear blocks.
The improved appliances for locking the horn shaft comprise a key or keys fixed
on the said shaft which together with the key or keys works through holes of
corresponding shape formed in brackets fixed to the machine.
Adjoining the holes in the brackets are second holes in which are hollow split
blocks, and in each block is a cone or wedge of metal, connected by adjustable
links to a toggle joint operated by connecting rod and can or tappet on a driven
shaft of the machine, and also by means of a return spring. When in operation
and at the required time the wedges or cones are forced into the split blocks which
then expand and press against the keys on the vertical shaft and so lock the latter
in position.
One end of the link for operating the slide may be attached to a compound lever
instead of arm hereinbefore mentioned.
Part of the compound lever is mounted on an axis and one end of such lever is
by stud and block connected to the other part of the lever, and the block and stud
being carried in a slot with adjusting screws at each end, the position of the stud

page_text: can be adjusted and consequently the length or stroke given to the slide can be
regulated.

COMPLETE SPECIFICATION.
Improvements in Nailing, Sprigging, and Pegging Machines
Employed in Boot and Shoe Manufacture.
I, RICHARD WILKINSON BATEMAN of 5 Hanover Street, Halifax in the County
of York Shoemaker 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 improvements in nailing sprigging and pegging machines
employed in the manufacture of boots and shoes and consists
Firstly. Of an improved adjustable feed motion for feeding serrated wire or
continuous lengths of nails, sprigs or rivets to the cutting dies or shear blocks in
nailing sprigging and pegging machines employed in the manufacture of boots and
shoes.
"
Secondly. To improvements in the method of and means employed for locking
in position the vertical shaft which carries the "horn or stoop of machines as
aforesaid employed in the manufacture of boots and shoes.
Such being the nature and object of the said invention the following is a
complete description of same reference being had to the accompanying drawings in
which :-
Fig. 1 is a front elevation of part of the head of a machine for purpose aforesaid
and having the improved feed motion applied thereto.
Fig. 2 is a plan view of part of Fig. 1.
Fig. 3 is a side elevation of Fig. 1.
Figs. 4 and 5 are details drawn detached in order to more clearly shew their
construction.
Fig. 6 is a side elevation partly in section of the improved mechanism for
locking the horn shaft.
Fig. 7 is a sectional plan view on line A. B of Fig. 6 drawn to an enlarged
scale.
Fig. 8 is a sectional side view of the locking device.
According to this invention the adjustable feed motion is designed to feed or
supply to the cutting dies or shear blocks continuous lengths of nails, sprigs or
rivets which have been previously partly prepared or manufactured by nearly
severing the metal bar strip or wire 1 from which they are made. The continuous
length of nails sprigs or rivets 1 are passed along a groove or recess 2 and through
aslide piece 3 carried in the slide bed 4 in the head 5ª of the machine. In the
slide is a catch or pawl 5 the point of the latter entering one of the nicks or
recesses 6 between the head of one nail and the point of the next succeeding nail
and as the slide 3 is moved forward as hereinafter described a distance equal to the
length of the nail or sprig to be fed the wire or bar 1 is fed forward the required
distance. The slide 3 carrying the pawl 5 is operated by a scroll or wiper tappet
or cam groove 7 acting on a pin 9 in the toothed segment arm 8 the latter in turn
acting on a toothed segment 10 fast on a shaft 11 carried in a bracket 12 fixed to
the head 5 of the machine. The tappet or cam groove 7 gives an oscillating
motion to the segment arm 10 and by the latter to an arm 13 to which is fixed a
link 14 the upper end of which is attached to the slide 3 so that an up and down
motion is imparted to the latter which is thereby slided in the slide bed 4 for ned

page_text: in the head 5 of the machine and the continuous nails 1 are thereby fed to the
shear blocks such as are described in Specification of Letters Patent No. 8496
dated 5th day of May 1892 and granted to the present applicant.
One end of the link 14 for operating the slide 3 may be attached to a compound
lever 15 instead of to the arm 13 herein before mentioned.
The part of the compound lever 15 shewn by Fig. 5 is mounted on the axis 11
and one end of such lever is by stud 17 and block connected to the other part 13
of the lever 15 the stud 17 being received in the hole 19 and the block and stud 17
being carried in a slot 20 with adjusting screws 21. 21 at each end the position of
the stud 17 can be adjusted and consequently the length of stroke given to the
slide 3 can be regulated.
The improved appliances for locking the horn shaft 1 (see Sheet 4) comprise
keys 2, 2 fixed on the said shaft I which together with the keys 2, 2 work through
holes 3, 3 of corresponding shape formed in brackets 4, 4 fixed to the machine.
Adjoining the holes 3. 3 in the brackets 4. 4. are second holes 5. 5 in which are
hollow split blocks 6. 6. either straight or conical and in each split block 6 is a
cone or wedge 7 of metal connected by adjustable links 8. 8 to a toggle joint 9
operated by connecting rod 10 and cam or tappet 11 on a driven shaft of the
machine, and also by means of a return spring as described in Specification of
Letters Patent No. 8496 dated the 5th day of May 1892 and granted to the present
applicant. When in operation and at the required time the wedges or cones 7 are
forced into the split blocks 6 which then expand and press against the keys 2 on
the vertical shaft 1 and so lock the latter in position.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. The general construction arrangement and combination of parts constituting
the improved adjustable feed motion as and for the purpose herein described and
substantially as illustrated by Figs. 1 and 3 of the annexed drawings.
2. The catch or pawl 5 slide 3 link 14 arm 13 lever 15 with means of adjustment
and segment 10 all in combination as and for the purpose herein described and
substantially as illustrated by Fig. 3 of the annexed drawings.
3. The horu shaft 1 with keys 2. 2 split blocks 6. 6 and cone or wedge 7. 7 all
in combination as and for the purpose herein described and substantially as
illustrated by Sheet 4 of the annexed drawings.
Dated this 28th day of September 1894.
