DAVID C. McCALIB, OF EL PASO, TEXAS.
RAILWAY-SWITCH.
941,089. Specification of Letters Patent. Patented Nov. 23, 1909.
Application filed May 20, 1909. Serial No. 497,214.To all whom it may concern:
Be it known that I. DAVID C. MOCALIB, a
citizen of the United States, residing at El
Paso, in the county of El Paso, State of
5 Texas, have invented certain new and useful
Improvements in Railway-Switches; and I
do hereby declare the following to be a full,
clear, and exact description of the invention,
such as will enable others skilled in the art
10 to which it appertains to make and use the
same.
This invention relates to railways and
has special reference to a switch adapted to
be operated from a moving car, engine or
15 the like.
One object of the invention is to improve
the general construction of railway switches
of this character.
Another object of the invention is to im-
20 prove the general construction of the means
supported by the train or car for operating
switches of this character.
A third object of the construction is to
provide a novel form of switch of this char-
25 acter wherein the moving parts will be sub-
stantially all held within casings.
With the above and other objects in view
the invention consists.in general of a novel
form of railway switch comprising operat-
30 ing parts held adjacent the rails of a track
together with a novel form of actuating
means.
The invention further consists in certain
novel details of construction and combina-
35 tions of parts hereinafter fully described,
illustrated in the accompanying drawings,
and specifically set forth in the claims.
In the accompanying drawings, like char-
acters of reference indicate like parts in the
40 several views, and :-Figure 1 is a top plan
view of a railroad switch constructed in ac-
cordance with this invention. Fig. 2 is a
side elevation thereof partly in section show-
ing a switch constructed in accordance with
45 this invention together with a portion of
the train supported mechanism for operat-
ing the switch. Fig. 3 is a transverse section
on the line 3-3 of Fig. 1. Fig. 4 is a simi-
lar section on the line 4-4 of Fig. 1. Fig. 5
50 is a detail section or view of the train sup-
ported mechanism in inoperative position.
Fig. 6 is a similar view of the train sup-
ported mechanism in operative position.
Fig. 7 is a view partly in section of the
55 train operative mechanism taken at right
angles to Figs. 5 and 6.The numeral 10 indicates the line rails
of a railroad track and at 11 are shown the
siding or turnout rails.
At 12 are the usual switch points which 60
are connected by means of a suitable brace 13.
At 14 are indicated certain casings which
extend longitudinally of the track and
wherein are held certain of the moving
parts. Each of these casings 14 is provided 65
with spaced bearings 15 wherein is mounted
a shaft 16 provided with laterally extended
curved arms 17. A cover 18 is provided for
each of these casings and this cover has
downwardly inclined ends as indicated at 70
19. The cover 18 is normally held in a
raised position by means of suitable springs
20 which extend from the under side of the
cover to the bottom of the casing 14. Upon
the top of the cover 18 are mounted a plu- 75
rality of supporting forks 21 each of which
carries a roller 22 which is adapted, when
the cover is depressed, to contact with one
of the arms 17. These casings 14 are here
indicated as four in number, there being 80
two on what may be termed the inside of the
switch, one adjacent the switch between the
rails and a fourth adjacent the switch out-
side of the rails and upon the opposite side
of the switch from the third. The first two 85
casings are joined by a curved portion 23
and the two shafts 16 in these casings are
connected by means of a universal joint 24.
It will be seen from an inspection of Fig. 1
that three of these casings are arranged par- 90
allel to each other and the shafts 16 in each
of the parallel casings are provided with
sprockets 25 which engage a sprocket chain
26 which extends transversely of the track
being held in a suitable casing 27. This 95
casing 27 is provided with a slot 28 and the
upper side of the sprocket chain is held sub-
stantially in the slot being connected to the
switch point 12 by means of suitable bolts
29. It will be observed that the arms 17 100
project from different sides of the shaft .16
in the several casings and the purpose of
this will be hereinafter apparent.
At 30 is indicated the floor of a car or
the like and on this floor is mounted a cas- 105
ing 31. Within the casing 31 there is pro-
vided a bearing 32 and an operating lever
33 has one end attached to this bearing, be-
ing provided at its free end with a treadle
34. Supported beneath the floor of the car 110
is a guide sleeve 35 wherethrough passes a
plunger 36 having its upper end connected
