SPECIFICATION forming part of Letters Patent No. 506,242, dated October 10, 1893.
Application filed October 3,1892. SerialNo.447,765, (No model.)
To all whom it may concern:
Be it known that I, MICHAEL L. LYNCH, a
citizen of the United States, residing at Fort
Worth, in the county of Tarrant and State of
5 Texas, have invented a new and useful Cat-
tle-Guard, of which the following is a specifi-
cation, reference being had to the accompany-
ing drawings, forming part of this specifica-
o My invention relates to cattle guards for
railway purposes, and is distinguished from
other guards by the manner of combining the
materials of which it is constructed and is
illustrated in the accompanying drawings, in
Figure 1 is a vertical section at right an-
gles to the line of track. Fig. 2 is a top view.
Fig. 3 is a cross section taken on line x--x
o Similar letters refer to similar parts in the
A shallow pit is first excavated the width
of the roadway. Upon the floor of this pit
are laid transversely to the line of track the
5 cross or bridge ties A. A'., in pairs, A' on top of
A, the top tieA' of each pair being beveled to
a sharp edge, as shown. At each end of these
ties another tie B, is laid on top of ties A,
A'. to form a guard rail, and these also are
o beveled to a sharp edge as shown, on their
upper surfaces. Ties B, B are shouldered
over and drift bolted by bolts C, C to ties A.
A. as shown. An end plank E. E, is securely
spiked to the outer face of each of the two
5 end pairs of ties A. A'., the upper edge of
said end planks being cut into V shaped ser-
rations properly spaced to receive the sharp
edged rail pieces which are securely attached
to them. These rail pieces D D D are set as
shown in the V shaped serrations, cut in the 40
upper faces of the end planks E E. In lieu
of the ordinary cross or bridge ties A A', such
ties may be specially prepared in one piece,
out of timber, or hollow metal ties, A shaped
with the sharp angle projecting upward may 45
be used, the said metal tie to be filled with
cement concrete introduced from the top, af-
ter the ties are laid in place, through the por-
tions cut out to receive the track rails F F;
also hollow iron A shaped intermediate rail 50
pieces D D may be used, which may be laid
on top of said A shaped metal ties in recep-
tacles cut out of the top edge of said ties to
What I claim as new, and desire to secure 55
by Letters Patent, is-
The combination in a railway cattle-guard
of sharp edged cross ties, resting directly on
the bottom of a shallow pit, and connected at
their outer ends by guard rails shouldered 60
over them and secured by bolts; end planks
having V shaped serrations secured to the
outer faces of the first and last tie, and pro-
jecting above them; and intermediate sharp-
edged guard rails fitted into the serrations of 65
said planks, substantially as set forth.
