PROVISIONAL SPECIFICATION.
An Improved Fence for Use Across Water-courses.
J, WILLIAM FREDERICK DENNIS, of 11, Billiter Street, in the City of London,
Mechanical Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to an improved fence for use across small water-courses or
gullies, which are sometimes full and at other times dry or comparatively empty;
the objects of the invention being, first, to prevent deer or other cattle straying,
when the level of the water is low or the bed of the river dry, and escaping by way
of the gully from an enclosure whence the water-course or gully leads; and secondly,
to provide a buoyant fence capable of being raised by the water so as to offer a
minimum resistance to the flow thereof in times of flood.
In a fence constructed according to this invention, a number of laths or strips of
wood are attached to carriers mounted on a horizontal bar arranged above the level
of the river and extending from one bank to the other; their free ends extending by
preference to the river-bed and resting thereon when in position to close the gully.
The laths are cut to various lengths, according to the configuration of the water-
course in cross section; all the laths, when resting on the river-bed, being inclined.
and lying approximately in the same plane. The wire or other fence appertaining
to the enclosure may be continued across the water-course above the pivoted subsidiary
fence above described.
According to one method of construction, I employ a horizontal bar formed of iron
tubing; each end being carried in a bracket (which may be adjustable altitudinally)
mounted on a standard erected on the gully-bank. Each end of the bar may, how-
ever, be perforated for the reception of a pin passing through the bracket as well as
the bar; the latter being thus held in place. Each lath or strip is made of wood,
and is bolted or otherwise secured at its upper end to a carrier threaded on the bar.
It will, however, be obvious that two or more laths may, if preferred, be attached to
the same carrier.
A fence of the kind herein described is also applicable for use across streams for
preventing or checking trespass. When so employed, the laths are of sufficient
length to reach the surface of the water when at summer level, but need not be further
extended towards the bed of the river.

An Improved Fence for Use Across Water-courses.
We ARTHUR DENNIS, of 11, Billiter Street, in the City of London, Mechanical
Engineer, and EDWARD BOWEN, of 9 Bevis Marks, in the City of London, Wine
Merchant, legal representatives of William Frederick Dennis, late of 11, Billiter
Street, in the City of London, deceased, 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 an improved fence for use across small water-courses or
gullies, which are sometimes full and at other times dry or comparatively empty;
the objects of the invention being, first, to prevent deer or other cattle escaping
(when the level of the water is low or the bed of the rivulet dry) by way of the gully
from an enclosure whence the water-course or gully leads; and, secondly, to provide

page_text: a buoyant fence capable of being raised by the water so as to offer a minimum
resistance to the flow thereof in times of flood.
In the accompanying drawings, Fig. 1 represents in front elevation a fence con-
structed according to the present invention; Fig.. 2 being a cross section on the
line 22 in Fig. 1. Fig. 3 is a corresponding plan.
The improved fence consists of a number of laths or strips of wood attached to
carriers mounted on a horizontal bar arranged above the level of the rivulet and
extending from one bank to the other; their free ends reaching by preference to the
bed of the rivulet and resting thereon when in position to close.the gully. The laths
are cut to various lengths, according to the configuration of the water-course in
cross section; all the laths, when resting on the bed of the stream, being inclined
and lying approximately in the same plane. The wire or other fence appertaining
to the enclosure may be continued across the water-course over the pivotted subsidiary
fence above described.
According to one method of construction, we employ a horizontal bar a formed of
iron tubing each end being carried in a bracket a¹ (which may be adjustable
altitudinally) mounted on a standard erected on the gully-bank. Euch end of the
bar may, moreover, be perforated for the reception of a pin a passing through the
bracket as well as the bar the latter being thus held in place. Each lath or strip c
is made of wood, and is bolted or otherwise secured at its upper end to a carrier d
threaded on the bar. It will, however, be obvious that two or more laths may, if
preferred, be attached to the same carrier.
A fence of the kind herein described is also applicable for use across streams for
preventing or checking trespass. When so employed, the laths are of sufficient
length to reach the surface of the water when at summer level, but need not be
further extended towards the bed of the stream.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we claim
1. For use across a water-course, a fence consisting of a series of pendent and
buoyant laths or strips pivotted towards their upper ends and having their lower ends
free to rise with the surface of the water in times of flood.
2. For use across a water-course, a fence comprising a horizontal bar a,
standards b, and laths or strips of wood c pivotted on carriers d, substantially as
described.
