Improvements in Galvanic Batteries.
I, WALTER SCOTT DOE, Electrician, of No. 281, 13th Street, Brooklyn, in the
County of Kings and State of New York, United States of America, do hereby
declare the nature of this invention to be as follows:-
This invention relates to a galvanic battery mainly designed for furnishing sufficient
electricity for lighting electric lamps used on bicycles, the battery being arranged to
permit the user to readily and conveniently recharge the same.
The invention consists principally of a perforated tube adapted to extend into the
exciting fluid and adapted to receive a depolarizer.
The casing of the battery is provided with a series of transversely extending
partitions forming a number of separate compartments, each compartment being
adapted to form a cell of the battery. In the compartments are set bottomless carbon
cylinders adapted to receive the exciting fluid, the walls of the cylinders being
perforated to permit a circulation of the fluid. Into the fluid of the several carbon
cylinders extend perforated tubes preferably made of hard rubber and extending with
tbeir upper ends through the tops of the cylinders and the cover of the casing, the
extreme upper threaded end of each tube screwing into a cap resting with its lower
edge on the top surface of the cover. Each of the tubes is adapted to receive a
depolarizing cartridge comprising an anode consisting of a zinc cylinder split.
longitudinally and adapted to receive a solid chemical preferably made of fused
nitrate of soda. The lower end of each of the cartridges rests on the bare end of
a conducting wire covered with a suitably insulating material and extending from
the tube through an opening in the wall of the carbon cylinder to a vertically.
extending recess formed in the outer surface of said cylinder. The upper extremity
of one of the end conducting wires passes through the cover to connect with a
binding post attached to the cover. The bare ends of the wires are supported in
place in the lower end of the tube by a transverse rubber pin secured to the tube.
In order to hold the cartridge in contact with the wire I provide a spring covered
with rubber or like material and secured to the cap to press with its lower end on the
top of the cartridge. The wires of the other tubes connect with the top of the adjacent.
cylinders.

*From the top of the other, end carbon cylinder, leads a conducting wire to a
binding post and in this wire is arranged a switch held on the outside of the cover to
open and close the circuit whenever desired. The cartridges in all the tubes are held
in place against the bare ends of the wires by springs in a similar manner to that
above mentioned, it being understood however that all the springs are secured at their
upper ends in the caps for the respective tubes so that when a cap is removed the:
spring can be lifted out of the tube to permit of inserting a new depolarizing
cartridge whenever the old one is used up.
In order to provide for the escape of gases I provide a spring valve normally;
closing an opening in the cover, said opening leading to one of the compartments
and the several compartments being connected with each other by apertures in the
upper ends of the partitions. The tops of the carbon cylinders are formed with
radial grooves registering with apertures formed in the tubes to permit of draining
the exciting fluid from the compartment. The duration of the light depends on the

according to requirements and when a cartridge is entirely used up it can be readily
be replaced by a new one, the operator for this purpose simply unscrewing the cap of
the corresponding tube or of all the tubes to insert a new cartridge in each tube and
to replace the cap with its spring.
It is understood that the exciting fluid in the battery lasts for a number of
cartridges in each tube and consequently renewal of the exciting fluid is not necessary
whenever the new cartridge is inserted. The chemical with which the zinc cylinder
is filled is preferably in a solid form in the shape of cylinders, pills, or the like. The
spring will always hold the cartridges in contact with the bare end of the conducting
wire so as to ensure a constant contact generation of electricity and consequently a
steady light in the lamp.

I, WALTER SCOTT DOE, Electrician, of No. 284, 13th Street, Brooklyn, in the
County of Kings and State of New York, United States of America, do hereby
declare the nature of this invention and in what manner the same is to be performed
to be particularly described and ascertained in and by the following statement :-
"This invention relates to an improved galvanic battery mainly designed for
furnishing sufficient electricity for lighting electric lamps used on bicycles but which
may also be used for other purposes, the battery being arranged to permit the user to
readily and conveniently re-charge the same so as to obtain a light for any desired
length of time.
The invention consists principally of a perforated tube adapted to extend into the
exciting fluid and adapted to receive a depolarizer.
The invention also consists of certain parts and details and combinations of the
same as will be fully described hereinafter and then pointed out in the claims.
Reference is to be had to the accompanying drawings forming part of this
specification in which
Figure 1 is a plan view of the improvement, with part in section, on the line 1-1
of Figure 2;
Figure 2 is a sectional side elevation of the improvement ; and
Figure 3 is a sectional plan view of part of the improvement on the line 3-3 of
Figure 2.
Similar characters of reference indicate corresponding parts in all the figures.
The casing A of the battery is provided with a cover A¹ and with a series of
transversely-extending partitions A2 A3 forming a number of separate compartments
each compartment being adapted to form a cell of the battery. In the compartments
are set the carbon cylinders (without bottoms) B B₁ B2 adapted to receive an exciting
fluid such as diluted sulphuric acid, the walls of the cylinders being perforated to
permit a circulation of the fluid in the respective compartments. Into the exciting fluid
of the several carbon cylinders B B B extend perforated tubes C C C² respectively,
preferably made of hard rubber and extending with their upper ends through the tops
of the cylinders and the cover A' of the casing, the extreme upper threaded end of
each tube screwing into a cap C³ resting with its lower edge on the top surface of the
cover A¹. Each of the tubes C C C is adapted to receive a depolarizing cartridge D
comprising an anode consisting of a zinc cylinder D' split longitudinally, and adapted

page_text: to receive a solid chemical D2 preferably made of fused nitrate of soda. The
cartridges D can be readily inserted in the tubes upon removing the caps C³ and
they are made of the desired length according to the length of time the electric light.
is to burn. The lower end of the cartridge D in the tube C rests on the bare end El
of a conducting wire E covered with a suitable insulating material and extending
from the tube through an opening in the wall of the cylinder B to a vertically-.
extending recess B³ formed in the outer peripheral surface of said cylinder. The
upper end of one of the conducting wires E passes through the cover A¹ to connect
with a binding post F attached to said cover. The bare end. E of the wire is
supported in place in the lower end of the tube C by a transverse rubber pin G,
secured to the tube. In order to hold the cartridge D in contact with the bare end. E'
of the wire E, I provide a spring H covered with rubber or like material and secured.
to the cap C³ to press with its lower end on the top of the cartridge D. The
cartridge D in the tube C' is likewise in contact at its lower end with the bare end E*:,
of a conducting wire E³ similar to the wire E and extending into a groove in the..
cylinder B' to connect with the top of the cylinder B, as plainly indicated in Figure 2..
A like connection is made between the top of the cylinder B' and the_cartridge D
in the tube C2 by means of a conducting wire E5 having its lower end E' supported.
in the lower end of the tube C². From the top of the carbon cylinder B² leads a
.conducting wire I to a binding post F¹ and in this wire upon the outside of the
cover A¹ is arranged a switch J to open and close the circuit whenever desired. The
cartridges D in the tubes. CC are held in place against the bare ends E2 and E* of
the wires E3 and E5 respectively, by springs H similar to the spring mentioned in
connection with the tube C, it being understood however that all the springs are.
secured at their upper ends in the caps for the respective tubes so that when a cap is
removed, the spring can be lifted out of the tube to perniit of inserting a new
depolarizing cartridge whenever the old one is used up. The conducting wires E³.
and E' are preferably made of platinum and the pins G for holding the same in place..
are preferably made of hard rubber.
In order to provide for the escape of gases forming in the casing A, I provide a
spring valve K normally closing and opening K¹ in the cover A', said opening leading:
to one of the compartments and the several compartments being connected with each
other by apertures A' in the upper ends of the partitions A2 A3 as shewn in Figure 2.
The tops of the carbon cylinders B B B are formed with radial grooves B4 registering
with apertures C formed in the tubes C C C² to permit of draining the exciting
fluid from the compartment when it is desired to renew the same. The duration of
the light depends on the size of the depolarizing cartridge, which can be manufactured
in different lengths according to requirements, and when a cartridge is entirely used
up it can readily be replaced by a new one, by simply unscrewing the cap C³ of the
corresponding tube or of all the tubes to insert a new cartridge in each tube and
to replace the cap with its spring.
It is understood that the exciting fluid in the battery lasts for a number of cartridges.
in each tube CCC and consequently renewal of the exciting fluid is not necessary
whenever a new cartridge is inserted. The chemical with which the zinc cylinder D'
is filled is preferably in a solid form, in the shape of cylinders, pills, or the like.
The spring H will always hold the cartridge in contact with the bare end E¹ of the
conducting wire, so as to ensure a constant contact generation of electricity and
consequently a steady light in the lamp.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is,
'
