City of Westminster, Gentleman, for the Invention of "AN IMPROVED
CONSTRUCTION OF METALLIC FENCING."-A communication from abroad by
MA Mvors of New York United States of America
PROVISIONAL SPECIFICATION left by the said Silas C. Salisbury at the
Office of the Commissioners of Patents, with his Petition, on the
12th May 1860.
I, SILAS C. SALISBURY, of Essex Street, Strand, in the City of Westminster
Gentleman, do hereby declare the nature of the said Invention for "AN
IMPROVED CONSTRUCTION OF METALLIC FENCING," to be as follows:-
The object of this Invention is to effect an economy in. the manufacture
and also in the fitting up of cast-iron fences. To this end hollow cast-iron
posts or pillars are used for supporting cast-iron panels which may be of any
ornamental pattern and are composed of sections of the full depth of the panel.
The sections of panels are cast with half round socket or shoulders to fit
against horizontal metal rods which rods when fixed in place extend from post
to post entering holes made for them in the posts near their upper and lower
ends. The sections for forming a panel are connected together and to the
rods by loose rings or collars made to fit into the sockets or shoulders of the
adjacent sections. The extremities of the rods are tapped to receive. screw.
nuts, by which the sections are tightened on the rods, and the rods are secured
in position by nuts which are placed on the ends of the rods, projecting. within

page_text: the hollow pillars, and screwed up tight by a spanner inserted within the
pillars, the upper part or cap being detachable, to give access thereto. To
the bottom of the pillars ground plates or blocks are bolted for the purpose
of giving the fence a good hold in the ground, and when the panels are
secured in place, the caps are to be applied to the pillars, and the fence is
complete. For ensuring firmness in the fence, filling rings are provided for
insertion between the loose rings or collars, and binding nuts on the rods when
such are required. The caps may be attached to the pillars or posts, either
by casting them with a screw fitting into a thread on the pillars, or by spring
catches, as thought most desirable. But they must in any case be made
detachable, to facilitate the removal of the fence, or the replacement of
damaged or broken panel sections.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Silas C. Salisbury in the Great Seal Patent Office on the
12th November 1860.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, SILAS
C. SALISBURY, of Essex Street, in the City of Westminster, Gentleman, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twelfth day of May, in the year of our Lord
One thousand eight hundred and sixty, in the twenty-third year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Silas C. Salisbury, Her special license that I, the said Silas C.
Salisbury, my executors, administrators, and assigns, or such others as I, the
said Silas C. Salisbury, my executors, administrators, and assigns, should at
any time agree with, and no others, from time to time and at all times
thereafter during the term therein expressed, should and lawfully might make,
use, exercise, and vend, within the United Kingdom of Great Britain and
Ireland, the Channel Islands, and Isle of Man, an Invention for "AN
IMPROVED CONSTRUCTION IN METALLIC FENCING," being a communication from
abroad by M. A. Myers, of New York, United States of America, upon the
condition (amongst others) that I, the said Silas C. Salisbury, by an instrument
in writing under my hand and seal, should particularly describe and ascertain
the nature of the said Invention, and in what manner the same was to be per-
formed, and cause the same to be filed in the Great Seal Patent Office within
six calendar months next and immediately after the date of the said Letters
Patent.

page_text: NOW KNOW YE, that I, the said Silas C. Salisbury, do hereby declare
the nature of the said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the
following statement, reference being had to the Drawing hereunto annexed,
and to the letters and figures marked thereon (that is to say):-
The object of this Invention is to effect an economy in the manufacture,
and also in the fitting up of cast-iron fences, which class of fences, although
they admit of being made of a highly ornamental character at considerably
less outlay than wrought metal fences, are yet very costly, by reason of the
elaborate nature of the moulds, when a large surface is cast in one piece, and
of the labor involved in connecting repetitions of small castings together in
the manner hitherto practised. To avoid these difficulties, it is now proposed
to employ hollow cast-iron posts or pillars for supporting cast-iron panels,
which may be of any ornamental pattern and are composed of sections of the
full depth of the panel fitted together by couplings which admit of being
very readily applied and as easily removed when required.
In the accompanying Drawing, Fig. 1 shews in elevation, a portion of
an extended panel of a fence composed of sections, and supported according
to this Invention, the pillar being partly in section, to exhibit the mode of
attachment employed. The part colored red represents the extent of one
section or casting. Its lateral extremities are cast with half round sockets
or shoulders, as shown in the detached view, Fig. 2, to fit against horizontal
metal binding rods a, a, which rods when fixed in place, extend from pillar to
pillar, entering holes made to receive them near the upper and lower ends of
the pillars. The cast pieces or sections for forming a panel, are connected
together and to the rods by loose clamping rings or collars b, b, strung on to
the binding rods, and made to fit over the sockets or shoulders of the adjacent
sections. At Fig. 3, one of these collars is shewn detached and in side view,
where it will be seen that its inner periphery consists of two segments of
different diameters, which form together a space just sufficient for the half
round shoulders of the abutting sections, to fit in and for the binding rod to
pass through.
It will, however, be undersood that this form of clamping
collar may be varied so long as the space corresponds with the figure made
by the abutting shoulders of the sections and binding rod in cross section.
The extremities of the rods a, a, aro tapped to receive screw nuts c, c, by
which the sections are tightened on the rods before applying the composite
panel to the pillars. To secure the sections to the binding rods it is only
necessary to lay them over the rods, slip the abutting shoulders under the rings
or collars b, and then apply the binding nuts to the opposite ends of these rods.

page_text: The panel thus composed is secured in position by inserting one end of the
binding rods in the holes made in the hollow pillars to receive them and
applying nuts d, d, thereto, which are to be screwed up tight by a spanner
inserted within the pillar, for which purpose the upper part or cap c, c, is
made detachable to give easy access to the upper nut while openwork in
the casting may be adapted for the insertion of a spanner to apply and
tighten up the lower nut. A second pillar is then applied to support the
other end and similarly attached thereto. The pillars are cast with external
or internal flanges to receive bolts for securing them to plates or blocks sunk
in the ground, and thus a good foothold is secured to the fence. When
the panels have been secured in place the caps are to be applied to the
pillars and the fence is complete. For ensuring firmness in the fence filling
rings are to be provided for insertion between the clamping rings or collars
and the binding nuts c, c, on the rods when such are required to prevent
all lateral motion of the sections of the panel, or otherwise the clamping
rings might slip off the abutting shoulders and the sections would drop out of
place. The pillar caps e may be attached to the pillars by casting them
with a screw fitting into a thread on the pillars, or if thought more desirable
by spring catches f, as shewn in the Drawing or otherwise. In any case they
must be made detachable to facilitate the removal of the fence or the
replacement of damaged or broken panel sections.
Having now set forth the nature of the Invention of "An Improved Con-
struction of Metallic Fencing," as communicated to me from abroad, and
explained the manner of carrying the same into effect, I wish it to be under-
stood that under the above in part recited Letters Patent, I claim the
combination of parts as above described for effecting an economy in the
construction of cast-iron fences.
In witness whereof I, the said Silas C. Salisbury, have hereunto set my
hand and seal, the Twelfth day of November, in the year of our Lord
One thousand eight hundred and sixty.
