WILLIAM A. SMITH, OF SAN ANGELO, TEXAS.ELECTRIC PROD-POLE.
Specification of Letters Patent. Patented Dec. 26, 1916.
Application filed August 9, 1915. Serial No. 44,535.To all whom it may concern:
Be it known that I, WILTIAM A. SMITH, a
citizen of the United States, residing at San,
Angelo, in the county of Tom Green and
5 State of Texas, have invented certain new
and useful Improvements in Electric Prod-
Poles, of which the following is a specifica-
tion.
This invention relates to certain improve-
10 ments in electric prod poles to he used in the
place of the ordinary prod pole for driving
or controlling animals on ranches, stock-
yards, and similar places.
The object of the invention is to provide
15 a simple, compact, and practical apparatus
of this character which shall be capable of
efficiently generating an electric discharge
of sufficient power to produce the desired re-
sult.
20 In order that the invention may be clearly
understood, reference is had .to the accom-
panying drawing, forming a part of this
specification, and in which,
Figure 1 is a side elevation of the complete
25 prod pole;-Fig. 2 is an enlarged longitudinal
section through the same, parts being broken
away; Fig. 3 is a longitudinal section
through that end of the pole which comes
in contact with the animal; Fig. 4 is an end
30 elevation thereof; and, Fig. 5 is a fragmen-
tary longitudinal section on a still larger
scale, showing the operative parts of the in-
duction coil and condenser, such parts being
shown more or less conventionally so as to
35 illustrate the electric connections.
Referring to the drawings in detail, my
improved prod pole consists of three tubular
sections, which I have designated A, B, and
C. These sections may be made of sheet
40 metal, or hard fiber, or the like.
The tube 1 of section A has at one end a
metal ferrule 2, provided with threads to re:
ceive a. screw-threaded cap 3. This cap has
secured to the inside thereof a short helical
45 spring 4, the free end of which is adapted to
rest against the bottom of a battery cell here-
inafter described. The other end of the tube
1 of section A has a screw-threaded ring or
ferrule 5 secured thereto, adapted to engage
50 a similarly threaded ring 6 which is secured
to the tube of section B. This tube of sec-
tion B has secured to the opposite end a ring
or ferrule 7, threaded to enter a similarly
threaded ring or ferrule 8, secured to the end
55 of section C. The tube 9 of section C pref-
erably tapers from the end adjacent sectionB to its free end, for the sake of lightness.
The free end of the tube 9 of section C is
closed by a disk 10 of insulating material,
held in position by a ferrule 11, having a EL
flange as clearly shown in Figs. 3 and 4.
The contact points or.electrodes, adapted to
come in contact with the skin of the animal,
consist of short pins 12, having blunt or
rounded points, and set into the disk 10, as 65
shown.
The section A constitutes the handle of the
pole and is provided with a push button 15,
for controlling the electric circuit. From
this button extends a thin metallic strip 13 70
to the ferrule 2, and a similar strip 14 to the
ferrule 5, these strips being placed on the in-
side of the tube 1 and suitably insulated.
When the button 15 is pressed, the result is
to connect the ferrules 2 and 5. 75
In the section A is placed a battery car-
tridge 16, composed of a suitable number of
dry cells arranged end to end. The metallic
bottom of the left hand end cell forms one
terminal, while the end 17 of the carbon elec- 80
trode of the right hand cell forms the other
terminal. By meass of the spring 4, the ter-
minal 17 is. pressed into engagement with a
contact button 18, which is electrically con-
nected with one side 19 of a suitable con- 85
denser. This condenser may be of any de-
sired construction and is merely shown con-
ventionally in Figs. 2 and 5.
A wire 20 connects the button 18 and one-
side of the condenser with a vibrator spring 90
21. The free end of this spring is adapted
to make and break connection with a con-
tact screw 22. The screw 22 is connected
by means of a -wire 23 with the other side
of the condenser and with one end of the 95
primary winding 24 of an induction coil,
which is inclosed within the section B. The
other end of the winding 24 is connected
through a wire 26 with the ferrule 5. The
winding 24 incloses a soft iron core 25, the 100
end of which is set into a disk 28 of in-
sulating material, which disk supports the
vibrator spring 21. A suitable casing 27,
inclosing the condenser, may also be mount-
ed upon the disk 28. 105
A tube 29 of insulating material prefer-
ably surrounds the primary winding 24 of
the induction coil, and outside of the tube
29 is wound the secondary winding. 30. The
terminals of the coil 30 are brought to bind- 110
ing posts 32, carried by a disk 31 of in-
sulating material into which the end of the1,210,112.
