WILLIAM R. SCOTT, OF FORT WORTH, TEXAS.
CATTLE-GUARD.
GPECIFICATION forming part of Letters Patent No. 771,838, dated October 11, 1904.
Application filed September 8, 1902. Serial No, 122,541 (No model.)To all who2 it 7T2hay cofcera7?:
Be it known that I, WILLIAM R. SCOTT, of
Fort Worth, Texas, have invented certain new
and useful Improvements in Cattle-Guards,
5 of which the following is a specification.
This invention relates particularly to that
class of cattle-guards which is adapted to be
applied on the surface of ties between and
outside of the rails composing the ordinary
10 railroad-track, so as to completely occupy the
space between the usual "wing-fences" and
prevent the cattle from crossing onto the
right of way, all of which will more fully
hereinafter appear.
15 The principal object of the invention is to
provide a simple, economical, and efficient
cattle-guard.
A further object of the invention is to pro-
vide a simple, economical, and efficient cat-
20 tie-guard with upwardly --projecting pieces
which may be molded or cast in an economi-
cal manner.
Further objects of the invention will ap-
pear from an examination of the drawings
25 and the following description and claim.
The invention consists in the features, com-
binations, and details of construction herein-
after described and claimed.
In the accompanying drawings, Figure 1 is
30 a perspective view of a culvert, showing my
improved cattle-guard in position for use;
Fig. 2, a broken plan view of a cattle-guard
constructed in accordance with my improve-
ments looking at it from above; Fig. 3, an
35 end -elevation of the same, and Fig. 4 an en-
larged sectional detail taken on line 4 of Fig.
1 looking in the direction of the arrow. -
In the art to which this invention relates it
is well known that it is. very desirable that
40 some means be provided which will render it
practically impossible for live stock to enter
from the roadway onto the right of way over
a bridge, culvert, or any other place. It is
also well-known that a large number of de-
45 vices have been constructed and are in use
designed to accomplish this result, but that
they are all more or less objectionable and
fail so to do. My invention therefore is in-
tended principally to provide a simple, eco-1nomical, and efficient cattle-guard which will 50
make it practically impossible for- cattle to
cross over onto the right of way.
In constructing a guard in accordance with
these improvements I prefer to form it of
cast-iron, either in part or entirely malleable 55
and composed of a plate or body portion a,
having a multiplicity of upwardly-projecting
cone-shaped portions b and c cast integral
therewith. The edges of this plate are pro-
vided with notches d, cast therein, through 6o
which the ordinary spikes are driven to fasten
the same to the railway ties or sleepers. It
is well known that cast-iron is more or less
expensive when used in large quantities and
also that it is quite heavy. It is therefore 65
advisable that the parts be made as light as
possible, and, as shown in the drawings, the
upwardly - projecting cone - shaped portions
are "cored " out, as at e, forming openings
which extend clear through the sides thereof, 70
so as to render them as light as possible.
If the upwardly-extending projections are
made pointed, it will be understood by those
skilled in the art that there is a possibility of
cattle resting their feet on three or more 75
points and passing over the guard. In order,
therefore, to prevent this, the upwardly-pro-
jecting cone-shaped portions are made of va-
rious heights and arranged in staggered rela-
tion-that is, in diagonal lines-the cones b 8o
being highest, while the next diagonal line is
composed of -a lower set of cones c, the next
diagonal line being of the higher set b, and so
on in series, thereby arranging them in stag-
ered relation and minimizing the chance of 85
the cattle getting two or more points to rest
their feet on.
These guards are preferably made in sev-
eral sections-that is, sections to occupy the
space between the rails of the track and other 90
independent sections to occupy all the space
outside of the rails and between the wing-
fences (not shown) of the road-crossings or
through other points where it is desired to
keep stock out of the right of way. This ar- 95
rangement is adapted for the purpose of keep-
ing parts spiked down on the ties and per-
I mitting other parts or sections to be removedNo. 771,838.
