JOHN H. CROWLEY AND BERNARD M. TEMPLE, OF GALVESTON, TEXAS.
RAILROAD-SWITCH.
SPECIFICATION forming part of Letters Patent No. 291,988, dated January 15, 18c4.
Application filed July 13, 1883. (No model.)
To all wzhoow it 7nay concern:
Be it known that we, JoHN H. CROWLEY
and BERNARD M. TEMPLE, of the city of Gal-
veston, county of Galveston, and State of
5 Texas, have invented a new and Improved
Railroad-Switch; and we hereby declare the
following to bea full, clear, and exact descrip-
tion thereof, reference being had to the accom-
panying drawings, making part of this speci-
io location, in which-
Figure 1 is a plan view showing the siding
connected to the main-line track. Fig. 2 is a
plan view showing the siding disconnected
from the main line. Fig. 3 is a detail view,
15 showing the short switch-rail attachment.
Our invention relates to split switches, and
particularly is an improvement upon the
switch shown and described in Letters Patent
No. 277,684, and dated May 15, 1883, issued to
20 John H. Crowley and Bernard M. Temple.
Our invention consists in securing the short
switch-rail to a long guard-rail, instead of piv-
oting it to the end of the siding-rail or sup-
porting-plate, the said guard-rail having the
25 end remote from the short switch-rail spiked
securely to the track, and the end carrying the
switch-rail provided with lever or other lmov-
ing devices whereby the switch-rails are
thrown.
30 In order that those skilled in the art may
make and use our invention, we will proceed
to describe the manner in which we have car-
ried it out.
In the said drawings, A and A' are the main-
35 track rails, and B B' the side-track rails. At
the end of main-track rail A is pivoted the
butt-end of the longer switch-rail C. A long
guard-rail, D, lies alongside of the side-track
rail B', and between the rails B B'. This
40 guard-rail extends from about a point, a, be-
hind the buttof the long switch-rail C down to
the point of said rail. All that portion of the
guard-rail D from its end a down to a point
about opposite where the long switch-rail is
45 pivoted to main-track rail A is securely spiked
down to the ties; but the remainder of the
length of the guard-rail is not fastened to the
ties.
Secured to the side of the guard-rail, in a
manner hereinafter set out, is the short switch- 5'
rail E, which is designed to connect the side
rail B' withthe main-track rail A'. Theshort
switch-railE is secured to the guard-rail D by
means of bolts b, which pass through the rails
and intermediate bolsters, dd, inserted between 5.
the guard-rail and short switch-rail, so that
when the nuts are tightened the rails D and E
are rigidly secured to each other, a space in-
tervening, due to the bolsters d d.
In order that the guard-rail D and switch- 6(
rail C may always move together and maintain
a proper relative position, they are connected
by sundry tie-rods, i i i, and they move to-
gether to open or close the switch.
The lever to throw the switch is seen at L, 6:
and operates substantially in the same manner
as does the lever in Patent No. 277,681, here-
tofore recited. The guard-rail, when moved
by the lever at its loose end, springs over un-
til the short split rail registers with the side- 7(
track rail, and the track is in position to shunt
the train onto the side track.
It will be observed that there are in this
construction no short tie-rods between the
main-track rail and the short switch-rail, 7
thereby avoiding the breaking or bending of
them by a car running off the track.
Having thus described our invention, what
we claim as new, and desire to secure by Let-
ters Patent, is- 8c
In a split switch, the guard-rail D, secured
to the track at one end, a, and carrying on
its loose end the short split rail E, rigidly se-
cured thereto with intervening bolsters, d d,
in combination with the long pivoted switch- 85
rail C and lever L, all constructed, arranged,
and operated substantially as set forth.
