PROVISIONAL SPECIFICATION.
An Improved Galvanic Battery.
1, William HeNRY MUNNS, of 106, 107, and 108, Victoria Chambers, 55 and
56 Chancery Lane, in the County of London, Patent Agent, do hereby declare the
nature of this invention (a communication to me from abroad by George A.
Smith, of Halifax, Canada, Inventor,) to be as follows:-
This invention has reference to an improved galvanic battery, whereby a more
powerful current in proportion to size may be obtained, and which will admit of
the current being more easily regulated.
The improved battery to which this invention relates consists of an outer cell,
preferably made of porcelain, or the like. Suitable rods project internally from
the sides of the cell. Rods are also secured to the bottom of the cell, and have
their upper ends secured to the inwardly projecting rods aforesaid. These rods
serve as guides for a piece of board having an opening which is passed over the
element, and is secured thereto. By this means the element may be raised and
adjusted any height out of the fluid. Within the space between the vertical rods
or guides is located another internal cell, which contains the fluid and element.
The element comprises alternating rows of carbon and zinc rods. Bars of con-
ducting material connect the rods of each row, and insulating plates are placed
between the upper ends of said bars. Insulated bolts are passed through the
plates and secure the bars together. Suitable L-shaped plates are secured to the
opposite sides of the element, and the transverse bolts pass through the vertical
members of said plates, thus securing them in place. By means of bolts or screws
the other faces of the L-shaped plates are secured to the board which engages the
guide rods.

An Improved Galvanic Battery.
1,WILLIAM HENRY MUNNS, of 106, 107, and 108 Victoria Chambers, Chancery
Lane, in the County of London, Patent Agent, do hereby declare the nature of
this invention (a communication to me from abroad by George A. Smith, of
Halifax, Canada, Inventor,) and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement :-
Fig. 1 is a transverse section of my improved battery.
Fig. 2 is a side elevation of my improved battery showing the battery-case in
section.
Fig. 3 is an exterior view of the battery-case, and
Fig. 4 is a perspective view of the elements.
Similar letters of reference indicate corresponding parts in all the views.
The object of my invention is to construct a simple, inexpensive and powerful
battery for the use of physicians, surgeons, and experimentalists for generating a
strong current for operating induction-coils, galvano-cautery, running motors, and
for other purposes.
My invention consists in a battery formed of a cell for containing the exciting-
liquid, one or more elements formed of rods of zinc and rods of carbon, and

page_text: mechanism for plunging and lifting the elements and holding them at any desired
height, as will be hereinafter more fully described.
The cell A which contains the exciting-liquid B is enclosed in a case C interiorly
arranged, the rods a a' forming guides for the board which supports the zinc
rods c and the carbon rods d. The carbon and zinc rods are mounted in rows in
barse of conducting material, the several rows being separated from each other
by plates of insulating material. The bars e and the plates fare held in position
by bolts passing through the said bars and plates and through L-shaped plates h¹
clamping the several parts together. The bolts are insulated from the zinc plate
by rubber tubes surrounding the bolts. To the bare attached to the zinc rods c
is secured the binding post i and to the L-shaped plate ¹ is secured a binding-
post. The lower ends of the rods a a' are secured to the bottom of the case C
while the upper ends of the said rods are received in brackets k k projecting
inwardly from the sides of the case.
In the case C is journalled a rock-shaft E to which are attached one or more
arms l, said arm being connected with an car m secured to the under surface of the
board b. When there are two battery elements one arm I will suffice for raising
and lowering said elements, but when there are a large number of elements two or
more arms will be required. One of the arms is prolonged beyond the rock-
shaft E, and is connected with one end of the spiral spring n, the other end of which
extends through a bracket o attached to the side of the case C. The said spring n
nearly or quite counter balances the weight of the battery elements.
Upon the end of the rock-shaft E which projects through the end of the casing C
is mounted a lever F which extends underneath the carved ratchet-bar G attached
to the end of the casing and serves to raise or lower the elements by turning the
rock-shaft E. When the lever F is to be operated by hand it is arranged as shown
in full lines in Fig. 3, but when it is operated by foot it is extended downwardly
and its lower end is curved outwardly as shown in dotted lines in the same figure.
The battery is connected with the induction-coil and other apparatus by wires
inserted in the binding-post i j, and the elements are plunged more or less in the
exciting-fluid B by the movement of the lever F. When the battery is not in use
the elements are removed from the solution by moving the lever F in the opposite
direction.
The construction of my improved battery affords a large surface to the action of
the liquids, and the rods being separated permit of the free circulation of the
solution.
A portion of the front of the battery-casing is made removable to admit of
taking out the battery cell.
Having now particularly described and ascertained the nature of this my said
invention, and in what manner the same is to be performed, I declare that what I
claim is:
1. A battery element comprising alternating rows of carbon and zinc rods, bars
of conducting material connecting the rods of each row, insulating-plates between
the upper ends of said bars and the transverse bolts passing through said plates
and bars and insulated from the bar connecting the zinc rods, substantially as set
forth.
-
2. A battery element comprising the alternating rows of carbon and zinc rods,
bars of conducting material connecting the rods of each row, insulating-plates
between said bars, the L-shaped plates at opposite sides of the elements, and the
transverse bolts passing through the vertical members of the said plates and
through the said bars and insulating-plates, the bolts being insulated from the bars
connecting the zinc rods, substantially as set forth.
3. The combination with the cell having vertical rods or guides, of an element
in the cell provided with a board movable vertically on the said rods, a pivot arm
within the cell and connected to said board, and a lever on the outer side of the
cell for operating the said arm, substantially as set forth.

page_text: 4. The combination, with the cell having vertical rods or guides, of an element
in the cell provided with a board movable vertically on said rods or guides, and a
counter balanced pivoted arm within the cell connected to the said board and
provided exterior to the cell, with an operating-lever, substantially as set forth.
Dated this 25th day of November 1891.
