JOHN MURPHY, OF SAN ANTONIO, TEXAS.
G UARD-RAIL.
SPECIFICATION forming part of Letters Patent No. 649,067, dated May 8, 1900.
Application filed November 9, 1899, Serial No. 736,425. (No model.)To all whom it may concern:
Be it known that I, JOHN MURPHY, a citizen
of the United States, residing at San Antonio,
in the county of Bexar and State of Texas,have
5 invented a new and useful Guard - Rail, of
which the following is.a specification.
This invention relates to guard-rails for use
in connection with frogs or switches, although
it will of course be understood that it may be
io employed with equal efficiency upon curves
and in other places where guard-rails are com-
monly used.
One object of the invention is to provide a
construction in which the guard-rail will be
15 firmly held in place, so as not to spread, a'
further object being to provide a construc-
tion in which the loosening of the spikes of
the guard - rail, with the dangers incident
thereto, will be prevented.
20 An additional object is to provide means for
holding the guard-rail against endwise move-
ment and also for providing end pieces there-
for which will result in a gradual slope at the
ends of the guard-rail to prevent striking of
25 parts of a moving train thereagainst.
Still another object of the invention is to
provide a modification which is particularly
adapted for use where the web of the guard-
rail is shorter than that of the track-rail and
3o which construction is employed when the base
or flange of the track-rail is so wide as to pre-
vent the guard-rail lying sufficiently close to
the tread of the track-rail.
In the drawings forming a portion of this
35 specification, and in which similar numerals
of reference designate like and corresponding
parts in the several views, Figure 1 is a plan
view showing portions of track and guard
rails arranged and connected in accordance
40 with this invention. Fig. 2 is a section on
line 2 2 of Fig. 1. Fig. 3 is a plan view show-
ing a modification of the structure as applied
when the guard-rail is of less depth than the
track-rail. Fig. 4 is a section on line 4 4 of
45 Fig. 3. Fig. 5 is a section on line 5 5 of Fig.
3. Fig. 6 is a detail perspective showing the
supplemental wedge-block employed in the
construction of the modification. Fig. 7 is a
view similar to Fig. 1 and showing the appli-
50 cation of the end anchor for the guard-rail.
Fig. 8 is a detail perspective view showing
the end piece or anchor for the guard-rail.Fig. 9 is a section on line 9 9 of Fig. 7. Fig.
10 is a transverse section of the guard-rail on
line 10 10 of Fig. 7 and showing the engage- 55
ment of the fingers of the end piece or anchor
therewith.
Referring now to the drawings, and more
particularly to Figs. 1 and 2, 10 represents a
track-rail which is spiked to the ties in the 6o
usual manner and adjacent which is arranged
a guard-rail 11, the dimensions of which are
substantially as those of the rail'10 and which
guard-rail is likewise spiked in position. In
order to hold the guard-rail 11 against dis- 65
placement-that is, the lifting of one side of
its flange from the tie and permitting the
working of sand and dirt in under the side of
the flange to thus hold the supplemental rail
out of its operative position--these rails 10 7o
and 11 are properly spaced and have a spac-
ing-block 12 disposed between them. This
spacing-block 12 is adapted to hold the rails
against inward movement under the influ-
ence of the clamping action of a clamping" 75
chair 13 and which chair and its connected
parts hold the rails against separation. The
spacing-block 12 is so shaped that its lower
convexed face 14 will lie upon the webs of
the rails 10 and 11, while its side faces 15 and 8o
16 will lie against the inner faces of the webs
of the rails. The upper face of the block 12
is concaved, as shown at 17, the chord of the
concavity being less than the width of the
block to form shoulders 18 and 19, which rest 85
upon the under faces of the treads of the
rails. The chair 13 is substantially U-shaped,
with its upwardly-extending sides 20 and 21
disposed convergingly. Between the up-
wardly-extending side 20 and the web of the 90
rail 10 is disposed a clamping-block 22, which
is U-shaped in horizontal section, the pro-
jecting ends 23 and 24 of this block lying upon
the opposite. side faces of the portion 20, as
indicated. By this means the block 22 is 95
held against longitudinal displacement, and
when the chair is operated to draw the block
22 beneath the head of the rail 10 said block
will be held against upward displacement and
will be fixed in position. To thus move the 100
chair laterally, the side 21 thereof is disposed
at an angle to the side 20, and consequently
to the rail 11, and between the side 21 and
the web of the rail 11 is disposed a wedge-
