JOHN W. THOMAS, OF AMARILLO, TEXAS.
FROG AND GUARD RAIL FOR RAILWAY-TRACKS.
994,215. Specification of Letters Patent. Patented June 6, 1911.
Application filed September 17, 1910. Serial No. 582,568.r ~
To all whom it may concern:
Be it known that I, JOHN W. THOMAS, a
citizen of the United States, residing at
Amarillo, in the county of Potter and State
5 of Texas, have invented certain new and
useful Improvements in Frog and Guard
Rails for Railway-Tracks, of which the fol-
lowing is a specification.
My invention relates to improvements in
to frog-and-guard-rails for railway-tracks, and
my object is to provide a simple device of
this character containing certain features of
advantage hereinafter described.
In order that the invention may be fully
15 understood reference will now be made to
the accompanying drawing in which:
Figure 1 is a plan view partly in section
of the invention in operative position. Fig.
2, is a detail plan view of one of my frog-
20 and-guard-rails. Fig. 3, is a plan view of
one of my frog and guard rails applied to
a spring-frog.
1 and 2 designate main-line rails, and 3
and 4 designate branch-line rails.
125 5 designates the frog-point.
6 and 7 designate wing-rails communicat-
ing with rails 2 and 3, respectively, and
located at opposite sides of the frog-point
5, to which they are secured by bolts 8,
30 fillers 9 being interposed between said wing-
rails and the frog-point to leave space for-
the passage of flanges on the wheels of pass-
ing trains.
10 and 11 designate guard-rails located
35 adjacent rails 1 and 4, respectively. Guard-
rails 10 and 11 have segmental terminals 12
and 13, and semicircular ends 14 and 15
which latter have extensions 16 and 17 se-
cured, respectively, against wing-rails 3 and
40 2 by bolts 18, fillers 19 being interposed be-
tween said extensions and the wing-rails, as
shown in Fig. 1. Terminals 12 and 13 abut
against the out-turned ends 20 and 21 of the
wing-rails 3 and 2, respectively, to which
45 they are removably secured by plates 22 and
bolts 23.24 and 25 designate fillers interposed be-
tween frog-guard-rails 10 and 11 and rails
1 and 4 respectively, which are secured to-
gether by bolts 26 extending through the 50
fillers.
By curving the ends of the guard-rails
and having tiem engage the wing-rails and
the line-rails, it is obvious that said rails
will be reliably held in place and secured 55
from spreading apart or moving toward
each other, and by reinforcing the wing-
rails with extensions 16 and 17, said wing-
rails are protected from wearing and being
broken by the car-wheels passing over the 60
same, the extensions, in this respect, form-
ing important features of the invention.
When my improved frog and guard rails
applied to a spring-frog, as shown in Fig.
3, one of my improved rails is dispensed 65
with to permit action of the spring-con-
trolled wing-rail 2a during the passage of
a train.
Having thus described my invention what
I claim is: 70
1. In combination with the line and wing
rails of a frog, a frog-and-guard-rail curved
at each end and provided with an extension
adapted to lie against one of the wing rails,
and means for securing said frog-and-guard- 75
rail to the line-and-wing-rails.
2. In combination with the line and wing-
rails of a frog, frog-and-guard-rails each
curved at its ends and provided with an
extension adapted to lie against a wing-rail, 80
each of said frog-and-guard-rails also hav-
ing a portion paralleling one of the line
rails, substantially as described.
In testimony whereof I affix my signa-
ture, in the presence of two witnesses.
JOHN W. THOMAS.
