CROSS TIE FOR RAILWAYS
I
William E. Davis, Chattaroy, W. Va.
Application October 15, 1937, Serial No. 169,291
1 Claim. (Cl. 238-106)
This invention relates to cross ties for railways,
and the ‘purpose of the invention is to'increase
the anchorage of steel cross ties to minimize their
slipping endwise, as steel ties become dislodged
5 more easily than wooden ties because of their
lower. coeflicient of friction.
.
In transporting coal in mines, sidewise swaying
of the car, due to faulty alinement of the rails,
causes the coal that is heaped on the mine car to
10 roll off the sides, littering the haulway and caus
ing dust to accumulate. It also results in wrecks
from derailment ‘and retards the speed ' of the
car and increases the power consumed.
The use of steel ties in mines enables the build-~
15 ing of the railway with the tops of the rails as
‘ low as possible in order that the capacity of the
car maybe utilized to a maximum degree when
operating in low seams of coal.
'
The present invention, therefore, is designed to
effectually anchor the steel cross ties, regardless
2 O of the condition of the roadbed, and it is the
purpose of the inventor to produce a cross tie
which will be ef?cient and satisfactory. in use
and comparatively inexpensive to manufacture
25
and maintain.
4 ,
With the foregoing and other objects in View,
‘ the invention consists in the details of construc
tion, and in the arrangement and combination
of parts to be hereinafter more fully set forth
» 30 and claimed.
In describing the invention in detail, reference
rations or tooth-like projections H) with spaces
between them, in order that the projections may
imbed themselves, to a-greater or lesser degree
or extent, in a roadbed and, in fact, generally the
serrated ?anges will penetrate the roadbed to an
extent that the under surfaces of the base will
lie on the surface of the roadbed, and it is obvi
ous that when such anchorage is attained, the ties
will retain their positions to a degree that the
rails will not move transversely of a mine tunnel. 10
As has been stated, it is desirable in the use
of rails for mine cars to operate the cars with
asmuch clearance for the load as possible, for,
as is well known, when the clearance is reduced,
the size of the lumps of coal must be such as to 15
pass between the top of the mine car and the
roof of the tunnel and if the lumps are large, a
more economical mining operation and better
sale price results.
‘
In the modi?cation shown in Fig. 3, the base I I
has ?anges such as l2 and the teeth I3 01’ this
modi?ed construction are produced by curved or
approximately semi-circular recesses, so that the
distance between the teeth is increased as com
pared with the spaces between the teeth III. The
result is that there is a larger deposit of material
forming the roadbed between the teeth I3 and,
5
under some conditions, the cross tie will be held
to better advantage than where the spaces be
tween the teeth are in the shape of an inverted V. ‘ 0
It‘is to be understood that the inventor. does
will be had to the accompanying drawing form- ' not wish to be limited with respect to the, par
ing part of this application, wherein like char
acters denote corresponding parts in the several

Figure 1 illustrates a perspective view of a frag
ticular means of forming the anchoring teeth so I
'long as they are‘ comprehended within the terms
of the annexed claim. The teeth, of course, may
be formed by notching, scalloping or pinking the
edges of the ?anges, and preferably the cross tie
is formed by the well known rolling mill practices
Figure 2 illustrates a sectional view on the line whereby steel is rolled to produce the cross tie
40 2-2 of Fig. 1; and
1 with its depending ?anges, the bottom edges of 40
said ?anges having the aforesaid anchoring
Figure 3 illustrates a perspective view of a frag
ment of a track with cross ties embodying the
invention;
ment of a cross tie embodying a modi?cation.
In the drawing 5‘ denotes fragments of rails
,
‘which, of course, form no'part of the present
45 invention, but are shown assembled with the
cross ties and conventional rail fastening means 6.
The cross ties ‘I each comprises a rail supporting
base ‘with ?anges 8 and 9 at the longitudinal
edges thereof, and the said ?anges may be ‘at
.50 right angles to the base or. theymay extend
slightly outwardly, as shown in Figs. land 2.
Each ?ange is‘provided with a'plurality of ser
means.
I claim:

I
A metal cross tie consisting of a metal plate
shaped to form a rail supporting base and inte- 45
gral depending relatively low ?anges whereby the
rails are supported thereby in close proximity to r
a roadbed, the edges .of said integral ?anges hav
ing V-shaped projecting teeth tapered to produce
sharp points and adapted to be imbedded or par- 50‘
tially imbedded in the‘ roadbed.
