NICHOLAS LONGORIA, OF LAREDO, TEXAS.
TORPEDO-CONTROLLING APPARATUS.Specification of Letters Patent.
Patented Aug. 12, 1919.
Application filed May 20, 1918. Serial No. 235,474.
To all whom it may concern:
Be it known that I, NICHoLAs LONGoRIA, a
citizen of the United States, residing at La-
redo, in the county of Webb and State of
5 Texas, have invented new and useful Im-
provementsin Torpedo-Controlling Appa-
ratus, of which the following is a specifica-
tion.
This invention relates to a torpedo con-
10 trolling apparatus, and one object is to pro-
vide a torpedo which may be controlled from
an airplane by means of wings or vanes
mounted on said torpedo for effecting depth
control by means of electrically operated de-
15 vices carried by the airplane.
A further object is to provide certain
novel means by which the position of the
vanes or wings carried by the torpedo are
inclined to such a degree as to effect the
20 submerging operation.
In the drawings:
Figure 1 is a view in side elevation.
Fig. 2 is a longitudinal section.
Fig. 3 shows the solenoids in top plan
25 view, for controlling the rudder.
Fig. 4 is a section of the one of the sole-
noids controlling the vanes.
Fig. 5 is an elevation of the contact rings
on the end of the reel.
30 Fig. 6 is a front elevation of the reel.
Fig. 7 is a diagrammatic view of the cir-
cuits for the solenoids controlling the rud-
der and vanes, and a motor driving the pro-
peller shaft, the circuits being supplied by
35 feed wires formed into a cable wound on ga
reel, the individual contact rings of which
have connection with individual switches in
the circuit of a generator.
The body portion of the torpedo is desig-
40 nated 10 and includes a head 12 carrying
explosive material and a firing device 14
mounted in the usual position. The tor-
pedo is provided with a keel 15 and an open-
ing in the upper side is closed by a door or
45 the like designated 16.
The propeller 17 is mounted on shaft 18
and is driven by an electric motor 19 receiv-
ing power from a suitable source such as a
generator carried by the airplane not shown.
50 The cable carrying the various wires for
the circuits described below is designated 21
and is wound on a drum 22 adapted to be
carried by the airplane. A rudder is shown
at 24 and is provided with a cutaway portion
55 25 for the accommodation of the propeller17. This rudder is controlled by a trans-
versely extending arm or the like designated
27 connected by means of short cables or the
like 28 with a transverse arm 29 mounted on
a staff 30 operated electrically by any suit- 69
able mechanism shown conventionally at 35.
Solenoids may be employed for this .pur-
pose, suitable means being provided for se-
curing the gradual movement of the staff or
shaft 30, such as will be required for the 65
purpose indicated.
The vanes or wings are designated 38
and 39 and are pivotally mounted . on a
shaft 40 by the operation of which the
inclination of the wings is varied. Springs 70
41 are connected with the ends of the
wings and suitable devices. 44 and -45
limit the movement of the wings. Shaft 40'
constitutes a crank shaft and carries a pul-
ley 47 with which a flexible device 48 is con- 75
nected, this flexible device passing around a
pulley 49 on a shaft 50, and having connec-
tion with any suitable means for producing
tension on the flexible member or cable 48
for rotating the crank shaft and effecting 80
the required movement of the vanes. As
shown in Fig. 1 there is a type of pin and
slot connection between the ends of the crank
shaft and the vanes.
One form of device which may be em- 85
ployed for the purpose here specified con-
sists of a downwardly depending arm 55
pivoted at 56 and carrying a laterally ex-
tending member 57 constituting the core of
a solenoid 60. The arm 55 is connected with 90
the cable or the like designated 48 at the
point 61.
If necessary or desirable, in order to pro-
duce the more gradual movement of the
vanes and rudder, I propose to employ any 95
well known form of retarding device in con-
nection with the solenoids, such as a piston
having a port therein operating within an
air cylinder.
I have shown diagrammatically the cir- 100
cuits for controlling the rudder, the wings
or vanes and the propeller, or rather the
motor operating the propeller, and a cir-
cuit connected with the device for firing
the charge in the event that it is to be fired 105
electrically.
The wires comprising the circuit leading
to the device for exploding the charge are
designated 66, the wires of the circuit effect-
ing the control of the wings are designated 1101,313,100.
