JAMES BARRY, OF GALVESTON, TEXAS, ASSIGNOR OF ONE-FOURTH TO
WILLIAM H. GAYLE, JR., OF HOUSTON, TEXAS.
RAILWAY- FROG.
SPECIFICATION forming part of Letters Patent No. 664,617, dated December 25, 1900.
Application filed Augost 3, 1900. Serial No. 25,780, (No model.)To all whom it may concern;
Be it known that I, JAMES BARRY, a citizen
of the United States, and a resident of Gal-
veston, in the county of Galveston and State
5 of Texas, have invented a new and Improved
Railway-Frog, of which the following is a full,
clear, and exact description.
This in vention relates to a frog for crossing
rails at switches or railway-crossings; and the
io object is to provide a construction which will
be more secure and durable than those pre-
viously employed.
This specification is the disclosure of one
form of the invention, while the claims define
15 the actual scope thereof.
Reference is to be had to the accompanying
drawings, forming a part of this specification,
in which similar characters of reference indi-
cate corresponding parts in all the views..
20 Figure 1 is a plan view of the invention.
Fig. 2 is a bottom plan view. Fig. 3 is a sec-
tion on the line 3 3 of Fig. 1. Fig. 4 is a sec-
tion on the line 44 of Fig. 1. Fig. 5 is an in-
verted plan view of the rails, showing their
25 connection with each other. Fig. 6 is a side
view of one of the rails, and Fig. 7 is a side
view of the other rail.
The rails a and b may be disposed at any
angle to each other to form either a railway-f
30 crossing or a switch, and these rails are each
formed of one integral structure, the rails
crossing each other, as shown. For the pur-
pose of permitting the rails to match properly
with each other the rail a is formed with a re-
35 cess a' in its bottom and the rail b with a re-
cess b' in its top, the two recesses matching
with each other when the rails a and b are in
place, so that the rail a crosses the rail b, .as
shown. The rails are thus mortised together,
40 and an accurate connection is thereby made
between them. The rail a has a groove a2 in
its ball for the flanges of the wheels passing'
over the rail b, and the rail b has a groove b2
in its ball for the flanges of the wheels pass-
45 ing over the rail a.
The frog comprises chairs or braces c,which
are two in number and located at each side of
the rails at the points where they cross, such
braces being shaped to conform with the rails
50 and to lie under the balls thereof and against
the webs, the chairs projecting in over thebase-flanges of the rails. These chairs have
outwardly-disposed flanges c' at their bases,
which lie on the railway-ties and which may
be spiked or otherwise secured thereto, as de- 55
sired. Frog-blocks d are fastened between
the rails at opposite sides of their juncture,
so as to steady the rails and also to fill the
angular point between them, thus preventing
persons from lodging their feet in this space. 6o
The frog-blocks d are provided with lugs d',
which are bolted to the rails, as shown.
As shown best in Fig. 2, the rails are pro-
vided beneath their base-flanges with two
tapering flanged base-plates e, the flanges 65
thereof being located at their sides and being
turned up over the base-flanges of the rails,
so as to be securely joined therewith. U -bolts
f are fastened to the flanges c' of the blocks
or chairs c and pass under the chairs. These 70
U-bolts are two in number and are disposed
transversely of the rails. A connecting-plate
g has its ends secured to the U-bolts f, the
plate extending between the U -bolts to hold
them rigidly together. The chairs c are fas- 75
tened to the rails and the whole structure se-
curely held together by transversely-disposed
bolts h, passing through the rails and chairs,
as shown.
Beneath the whole structure is arranged a 8o
base-plate i, which has strips i' at its side
edges, preferably integral therewith, which
strips are bent up over the flanges c' of the
chairs c and fastened to the vertical sides
thereof by the bolts h, before mentioned. 85
Having thus described my invention, I.
claim as new and desire to secure by Letters
Patent-
1. A railway, having crossing rails, chairs
or brace-blocks situated at the outer sides of 90
the rails, U - bolts extending between the
chairs and passing under the rails, and a con-
necting-plate fastened to the rails beneath
the chairs and extending from one U-bolt to
the other. '95
2. A railway-frog, comprising the combina-
tion with the crossing rails, of chairs located
at the sides of the rails, flanged base-plates
situated under the rails and having their
flanges engaged with the base-flanges of the xoo
rails, U-bolts extending between the chairs
and passing under the rails, a connecting-
