Year: 1898

page_text: Reprinted as amended in accordance with the decision of the Chief Examiner of
the 23rd July 1904 and of the Comptroller-General, of the 8th February 1907.
I, WILLIAM HENRY DORMAN, of the Green Hall, Stafford, Engineer do hereby
declare the nature of this invention to be as follows:-
This invention applies to machines used for driving hob nails, rivets, etc., into
boots and shoes and is a further improvement on the machine described in the
Specification of former Letters Patent granted to me, numbered 23363 and dated
A.D. 1895.
The present machine consists of a suitable base, column and head, or other con-
venient frame work,-preferably adjustable in its height-adapted to carry the
various working parts. In the head is a driving shaft receiving motion from a
pulley which may be put in engagement with a driving cone by means of a treadle
and wedge arrangement so as to drive the machine and be provided with springs
to raise the treadle and withdraw the wedge so as to stop the machine when the
operator's foot is released from the treadle. A cam may be used in connection with
the wedge which only allows the latter to disengage at the desired place and may
also throw into action a brake so as to ensure prompt stopping of the machine.
The shoe may be supported upon a jack" which may be of the form described
in the Specification of former Letters Patent granted to me No. 17407. A.D. 1894,
and illustrated in Figs. 1 and 2. A guard may be used to prevent the "jack
falling when released by the operator.
"
"
The nails or rivets are thrown into a revolving box which feeds them down an
inclined shoot to a nail carrier which carries them one at a time from the end of
the shoot to a position beneath the driver bar. The carrier is an arın with a
notched end to receive the nails and has a reciprocating revolving movement
between the shoot and the driving bar, derived from a cam on the driving shaft in
connection with a return spring and intervening gearing as in No. 23363. A.D. 1895.
A rapper is provided to agitate the nail shoot and a clearing wheel to remove nails
which fall wrongly on the shoot. A side guard and a top guard may be fitted to
the shoot to keep the heads of the nails from turning or rising as they travel down
and a semicircular cover may be provided over the nail carrier and a cover to the
mouth of the hopper.
If the nails are of iron the driver bar may be magnetized and by a suitable cam
movement be caused to lift the nails one at a time from the carrier which is then
moved away by its cam to make way for the driver to descend and drive the nail
into the boot sole. A step in the driver lifting can allows the driver bar to descend
as in No. 23363. A.D. 1895. The driver bar is driven down by the recoil of springs,

page_text: preferably of indiarubber, provided for the purpose. The cam roll by which the
bar is raised may be adjustable up and down on the bar to accommodate nail heads
of varying thickness. The driver bar may be provided with a nozzle to keep the
head of the nail in proper position.
If the nails or rivets are of brass the driver is not magnetized but the nails are
driven down through a spring nose piece into which they are fed one at a time by
the carrier. In this case the carrier may be a wheel with a number of notches
revolving a step at a time in a shell, the bottom of which is provided with a hole
over the nose piece into which the nail falls on arrival, and the wheel may be
revolved by a spring pawl and ratchet wheel.
An adjustable edge gauge is provided which may be set in or out and up or down
to suit the nature of the work in hand and is cramped with a set screw.
A top gauge is also provided against which the sole of the boot takes an upward
bearing.
A gauge for nailing in the middle of the shoe is also provided and is fitted with
a ring and cross slide so that the gauge may turn and travel with the shoe.
A shutter is provided to close the end of the nail shoot while the carrier is away
and another to shut the nail into the carrier as into No. 23363 A.D. 1895.
The carrier has a recessed top or pocket to suit the shape of the head of the nail
and the shutter may have a lip to correspond so that the nail head is prevented
from turning. The shoot shutter may have a lip which projects over the shoot
end when such is required to prevent the nail head descending too far.
The feed movement of the boot may be performed by the operator or may be
dono by the machine by means of a cam and lever. The feed lever has an adjust-
able throw variable in amount to suit the required spacing of the nails, and the
feeding foot may operate upon the head of the last nail driven, so that in the case
of a nail failing to feed from the carrier the foot having no nail head to act on
does not feed the shoe forward.
An adjustable slotted bush is provided by means of which the feed foot may be
made to move to and fro in a path inclined to the horizontal.
If desired the feed may be done with an awl.
The foot is adjustable and may have sides to receive the nail head so as to pre-
vent the nail from turning, or may be plain, or with a half round or other hollow
to suit the nail head. It may also be a tube with one side shortened or be in one
with the nose piece through which the nail is driven.
The point of the hammer may be flat or may be cupped to suit the shape of the
head of any particular nail.
Dated this 15th day of Septr 1898.
I, WILLIAM HENRY DORMAN, of the Green Hall, Stafford, Engineer, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following state-
ment:-
This invention applies to machines used for driving hob nails, rivets, etc. into boots
and shoes and is a further improvement on the machine described in the Specifica-
tion of former Letters Patent granted to me, nuinbered 23363 and dated A.D. 1895.

page_text: The present machine consists of a suitable base, column and head, or other con-
venient frame work,-preferably adjustable in its height-adapted to carry the

known manner from a pulley.
The shoe may be supported upon a "jack" which may be of the form described
in the Specification of former Letters Patent granted to me N° 17407. A.D. 1894 and
illustrated in Figs 1 and 2. A guard may be used to prevent the "jack" falling
when released by the operator.
The nails or rivets are thrown into a revolving box which feeds them down an
inclined shoot to a nail carrier which carries them one at a time from the end of
the shoot to a position beneath the driver bar. The carrier is an arm with a
notched end to receive the nails and has a reciprocating revolving movement be-
tween the shoot and the driving bar derived from a cam on the driving shaft in
connection with a return spring and intervening gearing as in N° 23363. A.D. 1895.
A rapper is provided to agitate the nail shoot and a clearing wheel to remove nails
which fall wrongly on the shoot. A side guard and a top guard may be fitted to
the shoot to keep the heads of the nails from turning or rising as they travel down
and a semicircular cover may be provided over the nail carrier and a cover to the

If the nails are of iron the driver bar may be magnetized and by a suitable cam
movement be caused to lift the nails one at a time from the carrier, which is then
roved away by its cam to make way for the driver to descend and drive the nail
into the boot sole. A step in the driver lifting cam allows the driver bar to
descend as in N° 23363 A.D. 1895. The driver bar is driven down by the recoil of

If the nails or rivets are of brass the driver is not magnetized but the nails are
driven down through a spring nose piece into which they are fed one at a time by
the carrier. In this case the carrier may be a wheel with a number of notches
revolving a step at a time in a shell, the bottom of which is provided with a hole

The base a supports the column sliding neck a² and head a³ of the machine.
The main shaft b is suitably driven in a well known manner by a friction cone
pulley, put into engagement by means of a treadle under the control of the
operator.
The nails are placed in the revolving box c which feeds them down the shoot c
to the nail carrier which carries them to a position beneath the driver bar e. A
rapper is mounted on a pivot f₁ and is alternately raised by the pegs of the
revolving cylinder and depressed by the spring so as to strike upon the pin f
and agitate the shoot c'
("
The hob nails when raised by the scoops c fall in all kinds of irregular positions
upon the shoot c. Those which fall point downwards with their shanks between
the two sides of the shoot as shown in Figs. 37 and 39 are all right and do not

page_text: require to be interfered with but those falling in any other position have either to be
put right or cleared off the shoot.
For the purpose of either putting right or otherwise clearing away the nails
which fall wrongly on the nail shoot I provide a clearing wheel c³ as shewn in Figs. 1.
42 and 43 which is made to revolve in the direction shewn by the arrow by means
of a band c' and pulleys c. c. driven froin the main shaft b. The wheel is placed
with the points of the teeth c just clear of the upper surface cs of the shoot
sides c. c¹o The inner sides c" of the teeth are so shaped that they just clear a
properly placed nail head but the teeth as they revolve clear away all nails which
are wrongly placed.
The teeth cupon one side of the wheel are opposite the spaces c¹ upon the other
side so that a nail if touched upon one side has a chance to get away on the other.
In some cases as in Figs. 23. 24. 27 and 28 there are many more teeth upon one
side of the wheel than upon the other, as for instance, three on one side and ten
on the other-which affords large clearance spaces for nails to fall away from the shoot
on one side while being struck by the more numerous teeth on the other side. This
repetition of blows upon one side of the nail has also a tendency to cause the nail
to revolve slightly and so is more likely to find its way properly into the shoot.
This is especially the case with nails otherwise difficult to deal with and particularly
those with heads of oblong shape which must not come down the shoot with the
longest way of the head across. In practice the wheel shewn in Figs. 19 and 20 has
been found successful with the nail shewn in Figs. 21 and 22, the wheel shewn in
Figs. 23 and 24 with the nail shewn in Figs. 25 and 26, and the wheel shewn in
Figs. 27 and 28 with the nail shewn in Figs: 29 and 30.
A guard Figs 1. 38 and 39-is used to prevent the nail heads rising which
may be such as shewn in Figs. 38 and 39 in which the nail head is free to turn
round, or if the nail head be oblong and therefore requires to be prevented from
turning the guard cs Figs. 36 and 37 is employed.
Figs. 51. 52 and 53 shew another sort of cover which may be used with nails
which are not required to be prevented from turning round and which affords a
view of the nails in the shoot.
The side plate c¹ is cramped by the thumb screw to the side c¹ of the shoot
in an open-ended slot c" so that the plate can be readily removed. The cover c20
is carried from the plate c¹ by a bracket c21 on which it can be adjusted vertically
by a slot c²² and cramp screw 23 to suit any height of nail head. The cover c20
runs under the clearing wheel to a point ct to receive the nail heads. This cover €20
may be used with nails having rectangular or other shaped heads which are
required to be prevented from turning round, by providing a side-guard as shewn
in dotted lines in Fig. 52 which lies against the side of the head of the nail. The
sides c¹s and are rectangular below the wheel but bevelled away at c. ca above
the wheel to allow the displaced nails to fall easily.
So that the can roll e inay be adjusted vertically on the driver bar e to accom-
modate varying heights of nail head it is mounted on a bracket e²-Figs 31 and 32-
which is cramped by screws to the bar. Both bar and bracket are provided
with teeth e which interlock and prevent slip of the bracket on the bar.
The nose piece is of brass or non-magnetic and has a recess e to receive the
nail head and keep the same in proper position. It is cramped to the magnetized
bar e by a set screw e'. Another form of nose piece is shewn in Fig. 54 in which a
coiled spring elo is introduced which yields and allows the nose piece e¹¹ to give way
should it strike upon an already driven nail head. This nose piece may be adjusted
by turning the sleeve portion e¹² so as to screw the saine higher or lower on the
thread e¹s formed on the hammer bar e" and may be cramped fast by the screw els
when adjusted. For a nail head which requires to be prevented from turning the
nose piece is formined as shewn in Figs. 55 and 56 in which the recess is made to
fit the nail head and a feather e is provided which may slide vertically in one of
several grooves formed at to receive it in the sleeve portion et

page_text: With brass nails the bar is not magnetized, as such would be of no use, but an
arrangement is used as shewn in Figs: 44. 45 and 46.
Upon the shaft 6 I provide a cam g which operates through a roll g' a lever g²
mounted on a pivot g³ in the head a³. The lever g² works a slide 9 and pawl 95 so
as to move round, a tooth at a time, a ratchet wheel 9" which carries a notched
disc ground in a nail retaining shell 98 so that the disc operates as a nail feeding
wheel. As drawn the feeding wheel g' has eight notches and the ratchet wheel
eight teeth one notch g' is opposite the shoot c¹ receiving a nail and the opposite
notch go is under the hammer bar es delivering a nail. The shell ge is a circular
pan with vertical sides and has a hole g¹ in it's bottom under the bar es large
enough for the nails to drop through as they arrive and for the bar es to follow
when driven down by its springs e Figs. 1 and 2.
Under the hole g₁ is a spring nose piece 912 which receives the nail and holds it
vertically in position over the shoe until the descending hammer bar e' strikes upon
the nail when the spring sides of the nose piece g12 yield and allow both the nail and
the end of the hammer bar to pass through.
The spring 13 maintains the roll g' in contact with the cam g and also drives
forward the pawl g' but should a nail get across so as to lock the disc g' to the
shoot the spring will fail to act and no damage will result. In so:ne cases I use
a divider which operates between the shoot end and the feed wheel so as to separate
the nail within the feed wheel notch from the next nail in the end of the shoot and
so prevent cross locking by a nail between the shoot end and the feed wheel.
The edge gauge h Figs 1 and 2 may be set up or down by slackening the set
screw hand slightly turning the gauge on the shaft. The shaft is free to
slide forward and backward in guides . h. and is prevented from revolving by an
arm 5 free to slide in a horizontal race h' parallel to the shaft h³
Upon the shaft is a collar which limits the forward movement and another
collar h which limits the backward movement. These collars are adjustable and
take on either side of the guide bracket . Carried on the collar " is a stop
pawl which lies horizontally, supported on the peg. The pawl may be made
longer or shorter by slackening the screws h" and adjusting the extension
piece by means of the slots ¹¹
As drawn the collar h is against the bracket and the end of the pawl exten-
sion piece against a stop peg h so that the gauge is in a forward position, which
may be more or less forward according as the gauge is set by the screw h¹ upon
the shaft h.
If a row of nails be driven round the edge of the sole with the gauge h in the
position shewn in Fig. 1. a second row may be driven parallel to the first row by
lifting the pawl extension and sliding back the gauge h until the notch h¹ takes
against the peg h". The thumb screw h¹ serves to cramp the shaft in any desired
position.
Figs. 6. 7 and 8 illustrate a top gauge. The downward projection i takes upon
the upturned sole of the boot and the hammer e drives the nails through the gap i.
After the first nail is driven it passes, as the boot is fed along, under the serrated
portion of the gauge which then acts upon the heads of the nails.
The middle gauge is illustrated in Figs. 3-4 and 35 and takes the place of the
gauge upon the shaft hits arinj lying horizontally across, as to the left of
Fig. 2. The horns j. j¹. take upon the boot upper near the edge of the sole. If the
set screw be free, the boot sole may be swung horizontally under the hammer so
as to drive curved lines of nailing in or near the middle of the boot sole. The boot
and the horns j. swing about the centre j' of the ring which is free in the race j
of the block except when locked fast by the screw. The block j. is mounted
in a horizontal slide 7 and when the screw is free the boot and the block may
be moved horizontally across so as to drive straight lines of nails up the middle, or
near the middle of the sole. The distance of these lines of nailing from the middle
of the sole is determined by setting the shaft h forward or backward by means of
the screw h¹³.

page_text: Figs: 9 and 10 shew an elevation and plan of the carrier d with its pocket k and
shutter. The pocket is fitted to the carrier & and is secured by means of a
screw so that it is easily removeable for the purpose of changing for different
sorts of nails. It is made of various sizes and shapes to suit the different nails as
is also the shutter 1. Fig. 12. shews a front view of the pocket and Fig. 13. shews
the pocket and shutter in longitudinal vertical section for one sort of nail. Figs. 14
and 15 in the same way for another sort and Figs. 16 and 17 for a third sort of
which Fig. 18 is a plan. Fig: 11 shews a plan of the detached shutter shewn in
elevation in Fig: 9.
Figs. 1. 2. 40 and 41 shew the method of feeding forward the boot. The foot m
acts upon the head of the nail last driven and feeds the boot forward so that in
case no nail is driven no feed takes place. The foot m is adjustable horizontally
upon the feed lever m² by means of a cramping screw m², slot m³ and tongue mt.
The feed lever m' swings upon the pivot m which is adjustable vertically in the
slots mo. m² for the purpose of regulating the amount of the feeding movement.
The lever is operated by a cam ms which is mounted on the shaft b and engages the
cam roll m For the purpose of giving a slight upward movement to the foot m
in returning and down again in feeding and also that this movement may be
variable in amount, the slotted bush m' is provided being fitted in a round hole mu
in the lever m¹ and held fast by the screw m¹². The pin m¹s is secured in the
frame a3 and as the lever m' is rocked by the cam m³ the inclined slot m¹ causes the
lever and foot to rise slightly as the foot returns and to fall slightly as the foot
feeds.
10
This rising and falling movement may be decreased by setting the slot m¹ more
level and increased by setting the slot more inclined which may be done by
slackening the screw m¹ and turning the bush m slightly in the hole m¹, after-
wards setting up the screw m¹² again. The height of the foot m may be set by
turning the pin m³, the larger portion m15 of which is made eccentric to the smaller
portion m so that if the nut m" be slackened and the pin m¹³ turned by its
head me the bush mo, lever m and foot m are set up or down, after which the
nut m is set up again so as to hold the pin m¹³ fast in the frame a³.

The clearing wheel shewn in Figs: 27 and 28. has extra clearance space provided
between the teeth to enable it to deal with nails such as shewn in Figs. 29 and 30

page_text: in which the head is of extra large diameter. The body of the wheel is reduced in
diameter and the teeth made of extra length so as to afford space between the body
of the wheel and the nail shoot for the passage of the head when the nail lies upon
its side on the nail shoot. The bevelled portion of the teeth as shewn in Fig: 28.
acts upon the nail heads as soon as the points of the nails begin to assume a proper
position in the nail shoot.
The method of operating the nail carrier d has been already described in the
Specification Nº 23363 A.D. 1895 previously referred to but the pocket Figs. 9
to 18 for receiving and supporting the head of the nail and keeping it in place by
preventing it from turning is a new feature specially designed to deal with hob
nails. The pocket as before stated is made in various shapes and sizes to suit the
nails being dealt with.
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.-In-a-machine-for-driving-hob-nails-into-boots,-the-use-of--a-revolving--elenring
