Application February 25, 1937, Serial No. 127,755
2 Claims.
This invention appertains to new and useful
improvements in electric railways and more par
ticularly to a toy railway construction.
' The principal object of the present invention is
to provide a railway constructed to simulate in
practically all details an electric railway of the
overhead power transmission type.
Another important object of the invention is
to provide a toy railway structure wherein the
parts are capable of quick mounting and dis
10
mounting.
Still another object of the invention is to pro
vide a toy railway of the overhead power trans
mission type wherein the transmission equipment
a can be used in conjunction with the conventional
type of trackway now in general use.
These and various other important objects and
advantages of the invention will become apparent
to the reader of the following speci?cation.

In the drawings:
Figure 1 represents a fragmentary top plan
view of the improved railway.
Figure 2 is a fragmentary side elevational
View of the railway.
Figure 3 is a vertical sectional view taken sub
25 stantially on the line 3—3 of Figure 2.
Figure 4 is a horizontal sectional view taken
substantially on the line 4--4 of Figure 3.
Figure 5 is a sectional view taken substantially
on the line 5-5 of Figure 2.
30
Figure 6 is a sectional View taken substantially
on the line 6—6 of Figure 2.
Figure 7 is a perspective view of one of the
transmission line sections.
M
Figure 8 is a perspective view of one of the
curved sections of the transmission line.
Figure 9 is a sectional view on the line 9—9 of
Figure 8.
Figure 10 is a perspective View of the overhead
transmission line section located above a switch
50 way.
Figure 11 is a sectional View on the line l|--ll
of Figure 10.
Figure 12 is a fragmentary perspective View
_ showing the base portion of one of the trans
mission line supporting poles.
Referring to the drawings wherein like nu
merals designate like parts, it can be seen in
Figure 1, that numeral 5 represents straight sec
tions of the trackway, while numerals B—'l rep
5 0 resent curved sections of the trackway, the sec
tion ‘I being connected up with one of the sec
tions 5 by suitable switch means 8.
At each endv oi each of the track sections is a
55 metallic tie member 9 with which the usual tie
(Cl. 191—40)
fasteners are customarily engaged for holding
the track sections connected together. However,
in carrying out the present invention, a base
plate It! is employed for each of the connected
ends of the trackway.
This base plate I0 is pro- 7 5
vided with upwardly and inwardly disposed side
?anges H which engage the ties in the manner
of the usual track connectors, but each of these
plates I8 is provided with a laterally extending
portion I2 to the outer end of which is secured the =17
block l3, from which rises the post I4.
As is clearly shown in Figures 3 and 4, the
upper end portion of the post I4 has a pair of
arms i5-—l5 secured each at one end to the post
id as at IS. A vertically disposed plate I‘! is se
cured by suitable means l8 between the outer ends
of the arms l5, while a second vertically dis
posed plater I9 is secured by means 26 between
the inner end portions of the arms [5. An eye
member?! on the upper end of the post 14 has the
hook end 22 of the brace rod 23 engaged there
with while the lower end of this brace rod 23 is
provided with the hook 24 engaged through an
0
opening in the upper portion of the plate l'l.
Wooden insulators 25—26 are provided for each 25
post [4 and each is provided with an eye 26’ at
its upper end disposed through an opening in the
corresponding plates I‘! or l9. An eye 21 is pro
vided at the lower end of each of these insulators,
which of course may be of some other material 69 0
besides wood and from these eyes 21 depend the
coiled extensible springs 28—-29. The spring 29
is attached to the lower end or eye 36 of the
spring 28.
As shown in Figure 7, the straight transmis
sion line section is generally referred to by nu
meral 3| and consists of the straight tubular
conductor 32 connected by the members 33 to the
longitudinally curved brace rods 34. One end of
the transmission member 22 has a pin 35 forced
into the same and at this point is located the
0
hook 36 which is engageable with the correspond
ing overlying spring eye 30. (See Figure 3.)
Each end of each of the brace members 34 is
provided with an eye 31 and these eyes 31 overlap
in the manner shown in Figure 6 with the eye
21 of the insulator 25 disposed through the same.
Thus the transmission line section is supported
in place. The curved section of the transmission
line is generally referred to by numeral 38 which
is provided with the tubular curved conductor
32a provided with the connecting pin 35a at one
end and the supporting hook 36a and valso the
brace rod 3411 connected as at 3311 to the con
55

ductor 32a, the brace rod 342 being provided with
the eyes 31a at its ends.
The type of transmission line section employed
over the switch area 8 of the trackway (see Fig
ure 1) consists of the elongated straight con
ductor 32b and the elongated curved brace rod
341‘: provided with the usual eyes 31b at its ends,
this brace rod 341) being connected by the mem
bers 33b to the conductor 32b.
Curving laterally away from the intermediate
portion of the conductor 32b is the branch con
ductor section 39 above which is the curved brace
member 4!! connected by members 4| to the con
ductor 39 and equipped with the end eye 42.
15 Suitable brace means 43 is provided between the
conductors 32b and 39 as well as between the
braces 40 and 34b and the said conductors 32b
and 39.
The conductors 32, 32a, 32b and 39 will be dis
20 posed. as much as possible directly over a center
of the trackway.
Furthermore, the eyes at the ends of the brace.
rods 34, 34a, 34b and 40 will have shanks which
are driven into the tubular brace member 34.

While the foregoing speci?cation sets forth the
invention in speci?c terms, it is to be understood
that numerous changes in the shape, size and
materials may be resorted to without departing
from the spirit and scope of the invention as
30
claimed hereinafter.
