PROVISIONAL SPECIFICATION..
Improvements in Boot Nailing, Screwing, and Pegging and like
Machines.
I WILLIAM HENRY DORMAN, of The Hawthorns, Newport Road, Stafford, in
the County of Stafford, Engineer, do hereby declare the nature of this invention
to be as follows:
This invention has for its object improvements in machines which are used for
nailing, screwing, pegging and similar operations employed in the manufacture of
boots aud shoes and relates to that part of the machine commonly known as the
horn or part which supports the boot during the operation of the machine upon it.
In order to render machines of the class above mentioned capable of being used
upon boots having long and stiff legs I make use of various styles of horns and
posts, of lengths and shapes to suit the nature of the work in hand and to facilitate
the placing of the boot upon the horn or post and its removal therefrom I
construct the parts in connection with the horn or post in such a manner that the
latter may be easily moved or swung away from the machine.
The horn or post may be constructed so that during the operation of the machine
it remains stationary and unyielding or it may be arranged to have a side move-
ment conformably with the feeding movement of the machine and may have a
downward yielding movement in connection with the feeding movement.
It may
be supported by a spring against the nailing or driving operation of the machine
or by a lever and balance weight and may be provided with a treadle but whatever
may be the construction and arrangement to suit the various classes of machines to
which my invention is applicable I always provide that the horn shall be capable
of being readily swung or moved away from the machine for the purpose of putting
on or removing the boot.
In one form of my invention intended to be used for vailing heels I provide a
vertical tubular post either straight or with a set off in it and I furnish the top of
this post with a spring supported anvil to receive the boot.
I carry this tubular
post upon a second post which is guided in bearings at its top and bottom ends and
supported against downward movement by a strong spring. The second post may
be drawn down against the supporting spring by a treadle or by a movement in
connection with the feeding movement of the machine. The top bearing I furnish
with a slide which is cramped fast to the machine frame when the post is upright
and the machine in operation but is slackened so that the post may move forward
into an inclined position when it is desired to put on or remove a boot. The bottom
bearing is pivotted to the machine frame so as to allow of the forward movement
of the post.

Machines.
I WILLIAM HENRY DORMAN, of The Hawthorns, Newport Road, Stafford,
in the County of Stafford, Engineer, do hereby declare the nature of this invention
and in what manner the same is to be performed, to be particularly described aud
ascertained in and by the following statement:-
This invention has for its object improvements in machines which are used for
nailing, screwing, pegging and similar operations employed in the manufacture of
boots and shoes and relates to that part of the machine commonly known as the
horn or part which supports the boot during the operation of the machine
upon it.
In order to render machines of the class above mentioned capable of being used
upon boots having long and stiff legs I make use of various styles of horns and
posts, of lengths and shapes to suit the nature of the work in hand and to facilitate
the placing of the boot upon the horn or post and its removal therefrom 1 con-
struct the parts in connection with the horn or post in such a manner that the
latter may be easily moved or swung away from the machine. The horn or post
may be constructed so that during the operation of the machine it remains
stationary and unyielding or it may be arranged to have a side movement con-
formably with the feeding movement of the machine as in the well known
"Standard Screw Machine" or may have a downward yielding movement in
connection with the feeding movement and be supported by a spring against the
nailing or driving operation of the machine, as described in the Specification of
Letters Patent granted to G. F. Redfern No. 21936 A.D. 1891, or a lever and
balance weight and a treadle may be provided, but whatever the construction and
arrangement to suit the various classes of machines to which my invention is
applicable I always provide that the horn shall be capable of being readily swung
or moved away from the machine for the purpose of putting on or removing the
boot.
In one form of my invention intended to be used for nailing heels I employ a
vertical tubular post such as described in the Specification of G. F. Redfern
No. 21936 A.D. 1891 already referred to (being therein called a "stump" and
illustrated in Fig. 14) either straight or with a set off in it and furnished with a
spring supported anvil or table to receive the boot. This tubular post is carried
upon a second post which is guided in bearings at its top and bottom ends and
supported against downward movement by a strong spring. The second post may
be drawn down against the supporting spring by a treadle or by a movement in
connection with the feeding movement of the machine. (See the before mentioned
Specification No. 21936, A.D. 1891.)
To enable the above described or parts used for a like purpose to be swung away
from the machine for the purpose of putting on or taking off a boot I improve the
construction as follows:-I furnish the top bearing with a slide which is cramped
fast to the machine frame when the post is upright and the machine in operation
but is slackened so that the post may move forward into an inclined position when
it is desired to put on or remove a boot. The bottom hearing is pivotted to the
machine frame so as to allow of the forward movement of the post.
My invention is illustrated by the accompanying drawings in which,
Fig. 1. is a side view of a nailing or pegging machine shewing my improvements.
Fig. 2. is a front view of the same.
Figs. 3 and 4 are a side and front view respectively of a screwing machine with
my improvements.
A (Figs. 1 and 2) is the base. B the column and C the head of the machine.

The horn or <
stump" D which supports the boot is of a similar construction to.
that described in the Specification already referred to No. 21936 A.D. 1891 and
like it is carried upon a vertical post" a as follows:-The post a is supported by a.
spring a and is capable of vertical movement in bearings a² a³.
The post a is
connected by a link at to a treadle a so that by depressing the treadle, which is
pivotted on a pin aº in the base A, the " stump D may be lowered against the
pressure of the spring a¹ and there is a screw collar or nut a' for regulating the
amount of the upward pressure exercised by the spring a', an india rubber washer a³-
is provided to lessen the shock when the treadle a³ is released.
The "stump" D consists of a round socket 6 which is clamped upon the upper-
end of the post a by means of the screw b. It may either be straight or have a
set in it and is furnished with a tubular piece 2 carrying a table or anvil 63-
supported by a spring . The work is supported on the table 63 and the spring b
supports the boot in contact with the guard c at the time when the feeding of the
work is taking place at which time the post a is drawn down by the action of the
machine as will be afterwards explained. If desired a weight d may be provided.
to bear up the "stump" D instead of or in addition to the spring a¹.
The
The drawing down of the "stump" D for the spacing of the nails or feeding of
the work may be accomplished in the same manner as described in the aforesaid
Specification No. 21936, A.D. 1891, or it may be done in a similar manner to that
described in the Specification of Letters Patent granted to C. F. Gardner
No. 2591 A.D. 1885 as follows:-A came upon the main shaft e¹ of the machine
operates a bell crank e² so as to raise and lower a rod e³ and frame e¹.
frame carries a pawl e' which on its upward stroke engages teeth formed in a.
rack bar e so as to lift the same which by a rod 7 is connected to the before
mentioned treadle a so as to pull down the post a through a short distance
immediately before the feed of the work takes place and the pawl e is afterwards.
lowered and released, when the feed movement is finished, so as to free the
treadle a and the post a.
In order that boots having long and stiff legs may be placed upon and removed
from horns or "stumps as above described, or of other construction, without risk
of injury to the boot I improve the construction of the machine as follows:-I
form the upper bearing a with a curved slide adapted to move in a race fl
formed upon the column of the machine and clamped therein when the post a
is in a vertical or other desired position by means of a screw f². I also provide
an adjustable stop screw f³ to exactly regulate the position of the table b³.
relatively to the nail driver x. The lower bearing a³ I form with trunnions
adapted to turn in bearings formed in a bracket y2 carried upon the column B..
By slackening the screw f² the post a and "stump" D may be swung forward.
into the position shewn by the dotted lines.
9. g¹
Figs. 3 and 4 .shew an arrangement of my improved horn which may be used
with a machine such as the well known "Standard Screw Machine" in which the
machine head and the horn move together sidewise during the feeding movement
relative to a fixed edge gauge against which the edge of the boot sole is held
by the operator. E is the column and F the head of the machine. The pulley h
gives motion to the vertical spindle which carries the worm gearing into
the worm wheel h³. This worm wheel ³ is mounted on the horizontal shaft h
which has at its rear end a cam operating a lever h°. The lever he is
formed with a vertical axis / pivotted in the machine head F and has at its
lower end an arm ³ engaging by a die h³ a slot formed in the upper part of
the column E. The head F is secured upon a vertical shaft G free to turn in
bearings i. formed in the top and bottom respectively of the column E. Upon
the shaft G, are secured an upper arm and a lower arm i³. Revolution of the
cam imparts movement to the lever he and arm 8 so as to swing the head F
and arms and 3 to and fro sidewise about the centre of the shaft G the
die acting as a fulcrum in the fixed column. The lower end j of the horn j¹

page_text: is supported by a washer upon a level surface ja prepared upon the base of
the column E.
So that the horn j¹ may be swung forward for the placing thereon and removal
of a long legged boot without risk of injury to the same form a hinge joint j
between the end j and the horn j¹ and I form the upper bearing through
which the horn passes with a curved slide adapted to move in a race
formed upon the upper arm 2 and clamped therein by means of a screw ja by
slackening which the horn j¹ may be swung forward into the position shewn by the
dotted lines.
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 machines for nailing, screwing, pegging and similar operations employed
in the manufacture of boots, pivotting the horn, or stump which carries the boot, at
its lower end in such a manner that it may be swung or moved from under the
machine head for the purpose of placing thereon or removing a boot, substantially
as described.
2. In machines for nailing, screwing, pegging and similar operations employed
in the manufacture of boots and in which a horn or stump is used to support the
boot the combination with such horn of the slide the cramp screw f² and the
adjustable stop screw f³ as described and for the purpose specified.
