WILLIAM T. GATES, OF AUBREY, TEXAS, ASSIGNOR TO THE GATES SAFETY SIGNAL I3OAiD)
ATTACHMENT COMPANY, OF AUBREY, TEXAS, A CORPORATION OF TEXAS.
TRAIN-ORDER SIGNAL.Specification of Letters Patent.
Patented ia 1,- , 1909.
Application filed June 18, 1907. Serial No. 379,539.
To all whom it may concern:
Be it known that I, WILLIAM T. GATES, a
citizen of the United States, residing at
Aubrey, county of Denton, and State of
5 Texas, have invented a new and Improved
Train-Order Signal, of which the following is
a specification.
This invention relates to signals for rail-
ways and more particularly to certain safety
10 signaling devices; and the object is to pro-
vide operators and despatchers with safety
devices which will operate automatically and
positively to prevent improper displays of
signals and the passage of trains withoutJ
15 orders. A separate order pad is kept for each
station on a railway to which an operator
must give orders. When an operator gets a
call to take an order, he cannot get the order
pad until he raises or displays the sema-
20 phore. Then he cannot lower the sema-
phore until he replaces the order pad in the
cabinet, and he will not do this until the con-
ductor takes the order. Thus a semaphore
cannot be thrown or cleared for passage until
25 the operator replaces his order pad in the sig--
nal cabinet.
Other objects and advantages will be fully
explained in the following description and
the invention will be more particularly
30 pointed out in the claims.
Reference is had to the accompanying
drawings which form a part of this applica-
tion and specification.
Figure 1 is a front elevation of the signal
35 cabinet, showing the actuating mechanism.
Fig. 2 is a side elevation of the same, this
view being the right sideof Fig. 1 and shoi-
ing the lever for giving an alarm and showing
the semaphore actuating mechanism. Fig.
40 3 is a side elevation, being the left side of
Fig. I and showing the main operating lver
and gearing for operating the semaphore.
Fig. 4 is a front elevation of the cabinet withn
the entire front part of the casing removed.
45 Fig. 5 is a vertical cross-section along the
line x x of Fig. 4. Fig. 6 is a vertical cross-
section along the line y y of Fig. 4. Fig. 7 is a
detail view of the contact making devices of
the alarm mechanism.
50 Similar characters of reference are used to
indicate corresponding parts throughout the
several views.
The devices set forth herein are adapted to
actuate signals of any ordinary construe-
55 tion, but for convenience of illustration asemaphore is set forth. A cabinet has sides
1 and 2 and a bottom 3 and a top 4 which
inake a rigid structure. A semp honeactu.-
atig shalt 5 is oun1ed in a d edoua led on
the sides of the cabinet, ourlr. bearings 6 0
being attached to the sides o the cabinet.
The shaft 5 does not rotate but oscillates
substantially 90 degrees. Opinions' ond& S1e
j mounted on shaft 5. 1hese i-ions are -
actuated by a lever 11 tough a sector 12. 65
The lever 11 and the sector. .12 are both
mounted on the shait 13 the lever 11 being
loosely mounted on the shaft and the sector
being rigidly mounted thereon. Te lever
must be movable in order to engage different 70
portions of the segmental rackc 14 which is
rigid with the side of the cabinet for the pur-
pose of locking the semaiphore shaft in oifer-
ent fixed positions. The leor 11 is held in
engagement with the rack 14, Iy a spring 1i 75
which is attaed to bthel-r 1 IatC1O end
iland presses agans % te sector 112. Th lever
( 11 is held in alineiment ti h oh sector 12 by
means of loops 16 and 17 which 1ar0 formed
integral with the sector 12. l The segmental 30
rack 14 is integral with the brace 1S and the
journal bearing 19 for shaft 13 is also inte-
gral with the brace . 1 Wfhen thie sector 12
drives the pinion and consequently the
shaft 5 and the pinion 7, the inO ' ive9 85
the sector 10 wiich is rigidly amounted on the
shaft and( door hinge 20 and the hlaf iand the
door linge 20 are also d'riven by the pinion
7 and sector 9 VWhen the s,,aft 20 is
driven the door 21 is opened. W\''hen the shaft 90
5 is driven or oscillated the semiapore is
raised or lowered. The shaft 5 drives the
pulley 22 and consuent.l the belt 23. The
belt 23 mnay run i iany suitable manner to
the shalt 24 of the smapiore. l The semi- 95
phore 25 is shown -m1ounted on a post 26.
The ca, ned-t issusplposed to be mOutC(d in an
0(l an Itohe- - 011x0d 1u 0f the
office to the semaphore. In the (lrawings
the belt 23 runs about the idle puileys 27 and 100
28, thvan under pulls 2 and 30, and up
over the pulley 31 whic is rigid witth he
semaphore shalt 24. With tie mechafn-
ism thus described the semaphore can be
raised or lowered at Sig(. 1.05
Means are provided for locking the sema-
phore up until the conductor has secured his
orders. A cam 32 is rigidly mounted on
shaft 5. This cam is provided 1ith an ab-
rupt shouideir 3. Lo kingdogs- 34 are pivot- 110No. 922,273.
