Year: 1854

page_text: LETTERS PATENT to Francis Puls, of Whitechapel Road, Philosophical
Instrument Maker, for the Invention of "IMPROVEMENTS IN ELECTRO-
GALVANIC APPARATUS FOR MEDICAL PURPOSES, PART OF WHICH IMPROVEMENTS
ARE ALSO APPLICABLE TO OTHER ELECTRO-GALVANIC APPARATUS."
Sealed the 5th June 1855, and dated the 11th December 1854.
PROVISIONAL SPECIFICATION left by the said Francis Puls at the
Office of the Commissioners of Patents, with his Petition, on the
11th December 1854.
I, FRANCIS PULS, of Whitechapel Road, Philosophical Instrument Maker,
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
ELECTRO-GALVANIC APPARATUS FOR MEDICAL PURPOSES, PART OF WHICH IMPROVE-
MENTS ARE ALSO APPLICABLE TO OTHER ELECTRO-GALVANIC APPARATUS," to be as
follows, that is to say:-
My said improvements have especial reference to the construction of a pocket
electro-galvanic apparatus for medical purposes, by which a more powerful and
beneficial action on the human body may be obtained than from any hitherto
in use.
My said apparatus is comprised in an oblong box of convenient size, divided
into two longitudinal compartments; one of which contains the battery, in a tray
of gutta percha, or other suitable insulating material; and the other, which is

page_text: divided breadthways, the conductors, and the apparatus for the induced current.
The battery is composed of plates of any metals hitherto in use for the purpose,
but so arranged, that each plate, whether of positive or negative metal, shall be
rigidly connected with the next plate but two before or after it in the battery,
the only exception being the second plate from one end of the battery. This
arrangement, which gives additional force to the electric current, by superseding
the ordinary plate cells, is applicable to electro-galvanic batteries used for other
than medical purposes. The induction apparatus is rendered adjustable by a
platina spring in connection with the coil.
I claim the general arrangement of the box and induction apparatus as
described for medical purposes, and the mode of arranging the plates in the
battery for electro-galvanic purposes generally.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Francis Puls in the Great Seal Patent Office on the
11th June 1855.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, FRANCIS
PULS, of Whitechapel Road, Philosophical Instrument Maker, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eleventh day of December, in the year of our Lord
One thousand eight hundred and fifty-four, in the eighteenth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
Francis Puls, Her special licence that I, the said Francis Puls, my executors,
administrators, and assigns, or such others as I, the said Francis Puls, my
executors, administrators, and assigns, should at any time agree with, and
no others, from time to time and at all times thereafter during the term
therein expressed, should and lawfully might make, use, exercise, and vend,
within the United Kingdom of Great Britain and Ireland, the Channel Islands,
and Isle of Man, an Invention for "IMPROVEMENTS IN ELECTRO-GALVANIC
APPARATUS FOR MEDICAL PURPOSES, PART OF WHICH IMPROVEMENTS ARE ALSO
APPLICABLE TO OTHER ELECTRO-GALVANIC APPARATUS," upon the condition (amongst
others) that I, the said Francis Puls, by an instrument in writing under my
hand and seal, should particularly describe and ascertain the nature of the said
Invention, and in what manner the same was to be performed, and cause the
same to be filed in the Great Seal Patent Office within six calendar months
next and immediately after the date of the said Letters Patent.

page_text: NOW KNOW YE, that I, the said Francis Puls, do hereby declare the
nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement (that is to say):-
My said improvements have especial reference to the construction or
arrangement of a certain description of electro-galvanic apparatus, by which a
more powerful electric action both in quantity and intensity may be obtained
than from any constructed according to the methods hitherto in use.
And in order to carry into effect the said Invention, I construct an apparatus,
comprised in an oblong or other shaped box of convenient size which contains
my improved battery, placed in a tray of gutta percha, or other suitable insu-
lating material, the said battery being formed by a series of plates of any
metals which have heretofore been used for the purpose, or may be found
suitable for the same; and the said plates being so arranged, that every pair of
the said plates, whether positive or negative, shall be rigidly connected, whether
by screw or soldering, with the next plates, in the manner shown in the
Drawings. The said arrangement, by which the plate cells hitherto in use
are superseded, is applicable to electric batteries for all purposes, and produces
additional force in the electric current.
But in order that these my said improvements may be more fully understood
and readily carried into effect, I now proceed to describe them by the aid of
the accompanying Drawings, reference being had to the letters and figures
thereon marked (that is to say):-
Fig. 1 represents a top or plan view of my improved electric apparatus ;
Fig. 2, a vertical section of the same, taken longitudinally through the dotted
line in Fig. 1; Fig. 3, a horizontal section, similarly taken through the
dotted line in Fig. 2; and Fig. 4, a transverse vertical section. In each
Figure the same letters of reference denote similar corresponding parts.
A, A, box or case of gutta percha or other suitable material; B, B, pro-
jections therein, for the purpose of retaining the plates in a vertical position;
C, C, partitions or stays of wood, gutta percha, or other suitable material,
for the purpose of keeping the plates apart; D, D, plates of the battery, positive
and negative alternately; E, E, lateral prolongations of the plates, by which
they are rigidly connected in pairs; F and G, end plates, or positive and
negative poles, to which the electrodes, or apparatus that the battery is to be
connected with, are to be affixed, through the medium of screws, solder, a
small cup of quicksilver, or otherwise. The said battery is to be a single fluid
battery with on cell, in which three or more pairs of plates can be inserted,
according to the purposes for which the said battery is to be employed.

page_text: Having now fully described the nature of these my said improvements, and
the manner in which the same are to be performed, I would have it clearly
understood that I do not by any means intend to confine myself to the precise
details herein-before described, as the same may be varied without departing
from the general principle of these my said improvements; but that which I
do claim as new and of my said Invention is, the arrangement and construction
of plates for a single fluid or dry battery with but one cell, without division
between the different pairs of plates, for medical and other applications, in the
manner and for the purposes herein-before set forth and described.
In witness whereof, I, the said Francis Puls, have hereunto set my
hand and seal, this Eighth day of June, in the year of our Lord One
thousand eight hundred and fifty-five.
Witness,
FRED R. D. CAMPBELL,
Clerk to Messrs. Weatherdon & Co.,
77, Chancery Lane.
