page_text: I, JOSEPH STOKES WILLIAMS of Riverton, New Jersey, United States of America
do hereby declare the nature of this invention to be as follows:-
My invention relates to improvements in portable electric apparatus for electric
lighting or other purpose provided with means for holding a reserve of electric
power and means for regulating and controlling the utilization of the said power.
(a) In such portable apparatus the magazine of electricity or secondary batteries
or accumulators are arranged within or combined with a stand casing or holder
and in combination with such arrangements I employ an electric circuit from the
battery or accumulator and means in combination with such circuit adapted to
operate either automatically or manually for regulating the electric force or energy
passing from such accumulator or secondary battery through the circuit to the
lamp or other working resistance or resistances employed for the utilization or
transformation of such force. The secondary battery or accumulator in such.
apparatus is of such a capacity that when charged and for some time after working
it will develop a pressure in the circuit higher than required for the lighting or
other electric work to be done and in combination with such arrangements
I employ electrical working resistance in the circuit which is adapted to operate
with a lower or reduced force than that primarily capable of development by the
said secondary battery or accumulator. I therefore employ a reducer or pressure
regulator in the working circuit of portable apparatus to operate either automa-
tically or at the will of an operator or arranged so that it can be operated both
ways so as to maintain practically a constancy in the units of energy discharged
from the secondary battery or accumulator until any minimum predetermined"
limit is reached or to enable the operator to vary the units of energy utilized for
lighting or other purpose. This regulator can consist of any suitable variable
resistance such for example as those herein set forth with reference to the
accompanying drawings,

page_text: (b) In the construction or working of such apparatus I preferably employ a
battery or accuinulator constructed as described in the Specification of my
application for Letters Patent Nd 13879 of this date by which means I increase the
storage capacity reduce the weight and bulk obviate short circuiting and render
practicable the charging of such battery with greater rapidity than is otherwise
practicable For such rapid charging the battery or accumulator is equipped with
charging conductors and terminal plates or sockets of the same or about the same.
conductivity as the electrodes or elements in the battery and I provide also
discharging conductors (which may either be independent of the charging conductors
or constitute branches thereof) of the necessary dimensions or conductivity to
provide for the passage through the working-circuit of sufficient current to meet
the requirements of the translating or transforming device or devices therein the
energy passed through the circuit in which the device or devices are in operation
is regulated or controlled by the employment of circuit controlling devices such
for example as those hereinafter described with reference to the accompanying
Drawings.
(c) In the construction of such portable apparatus I arrange the secondary
battery or accumulator so that it may be readily detached from the holder or
stand of the apparatus. by or from which it is 'suitably insulated when secured in
position. The said holder or stand may be constructed of insulating material for
instance vulcanised material cellulose Spence metal or metal lined with insulating
material so as to be adapted to support encase and secure the elements terminals
and parts as described in the Specification of the herein before referred to
application.
.
(d) In the construction of such.portable apparatus in order to prevent an excess
of current passing from batteries or accumulators through the working circuit as
herein set forth I employ an automatic pressure regulator which may consist of an
ordinary variable resistance or of a conical spherical or other suitably formed
plunger or movable part and a conductor either fixed or movable which forms
part of a loop or branch from the circuit including the translating device or
devices such for example as are more fully described hereinafter with reference
to the accompanying Drawings such pressure regulator can be operated automa-
tically or by a hand controlling device maintained in position by a contact spring
or friction clutch or a ratchet and spring as also more fully hereinafter described.
In these arrangements of portable apparatus the plunger or movable part of the
pressure regulator can be operated by an electric current passed through the main
circuit or a loop or branch therefrom constituting for example a solenoid the core
of which is combined through a lever or otherwise with such plunger or movable
part constituting the variable resistance so as to provide for the adjustment and
desired variation of resistance. In some cases in such combination I employ
plungers or movable parts adapted to work within an insulatory or insulated
chamber provided with suitable contact pieces or parts pointed or otherwise in
such a manner that the extent of movement of the plunger or movable part will
represent and regulate current passing to the translating device or devices or
through the working circuit such for example as is hereinafter described with
reference to Figure 10 of the accompanying Drawings.
(e) In such portable apparatus I may employ in combination with the circuit
closer or pressure regulator as set forth a conducting liquid in the insulating or
insulated chamber. For instance I can employ mercury for this purpose and
cover the same with an insulating liquid such as paraffine glycerine or the like.
Or I sometimes provide for regulating the conductivity through the medium of
rubbing-contacts held in position by a spring or the equivalent thereof such for
example as is hereinafter described with reference to Figures 1, 2 and 3 of the
accompanying Drawings with or without the medium of a non metallic liquid all
of which are enclosed in a suitable casing or chamber insulated or of insulating
material and preferably arranged to form a completed part with the terminals

page_text: and sockets so as to provide for connection with the elements of the accumulator or
battery provided with fitting parts insulated the extension of the circuit in which
the working resistance is included being connected therewith all as hereinafter
more fully described with reference to Figures 1 to 7 of the accompanying Drawings
so as to constitute a self-contained or portable apparatus.
(f) The arrangement and operation of the various parts of such portable
apparatus is such that when the circuit from the battery is completed for lighting
or other purpose and the hand circuit maker or automatic pressure regulator is in
its normal position (in which position it may be held when the circuit is broken
by a spring or weight) only a small or minimum amount of current can pass into
the working or translating circuit or I may employ the reverse of this arrangement
and in accordance with the increase of movement in the electric translating device
or solenoid core or the armature (caused by a variation in the current passing"
through such energizing or translating device) in the discharging or working circuit
or a loop therefrom provided for increasing or decreasing or regulating the energy
passing through the discharging or working circuit in other words the pressure
regulator will be automatically operated or adjusted in exact accordance with the
resistance in the discharging or working circuit or the pressure from the battery
or accumulator will regulate or vary the conductivity of the circuit in accordance
with the amount of work being effected therein or the variation of pressure from
the accumulator or battery.
(g) In some cases I provide in the equipment of such portable apparatus &
variable resistance adapted to be operated either manually or automatically and to
be adjustable through the medium of a screw as hereinafter described with
reference to Fig. 9. so as to control the amount of current passing through the
translating device such variable resistance may consist of a number of thin sheets
discs or laminae of carbon or other material of high resistance separated from ench
other by insulation and encased in the chamber as shewn at y in the said Figure 9
and provided with suitable terminals or connections therein in contact with which
suitable contact pieces are adapted to slide or be moved so that in accordance with
the extent of movement of such contact pieces either mechanically or electrically
so will the resistance in the circuit be increased or decreased and in order to
provide for regulating the pressure, in accordance with the resistance of the
translating device employed I provide for varying the position of the contacts
through the medium of a set screw (as at x Figure 9) as desired; A conical or an
equivalent formed part connected with the armature and also with the hand
device can be employed and arranged to vary the current from an ineffective
minimum to the maximum as hereinafter more fully explained with reference to
the accompanying drawings.
(h) In the construction of such portable apparatus I may provide in combination
with the holder or casing of or supporting the battery or accumulator thereof
means for intensifying or transforming force of the current in the discharging or
working circuit at variance with that emanating from the battery or accumulator
I employ for this purpose condensing or induction devices (simple or compounded)
provided with an automatic circuit changer or commutator or current undulator
interposed in the circuit thereof to the battery as hereinafter described aud
illustrated with respect to the parts L to J in the accompanying Drawings.
(i) In combination with such arrangement of apparatus I employ means to control
or regulate the current passing into or through these condensers or induction or trans-
forming devices from the magazine or battery or accumulator by the employment of
an automatic pressure regulator as herein after more fully described such device
being automatically operated by the current passing through the discharging
circuit of the battery or through a loop therefrom so that in accordance with the
variation of resistance in such circuit so will the conductivity of the circuit to the
condensers induction or transforming devices be regulated or varied. In portable
apparatus as set forth the circuit or circuits of the transforming or induction

page_text: devices can be combined with the circuits of the battery through a commutating
or switching device whose plungers or movable parts are adapted to operate so as to
alternately or consecutively place the elements of the induction or condensing devices
in the discharging circuit from the magazine or battery and in the discharging
circuit from such condensing or induction devices through the working circuit the
variable resistance is arranged to be operated in or upon such circuit to reduce or
vary the conductivity of the circuit both the accumulator or battery in accordance
with the work being done in the lighting or working circuit and when the band
controlling device or circuit closer in such circuit is in such position as to
interrupt the circuit of the battery or accumulator the main circuit from the
battery to the intensifying devices will be interrupted or such circuit or circuits
can be controlled by the hand device and a variable resistance combined there-
with with or without the employment of an automatic pressure regulator, or,
reducer.
(c) In such portable apparatus the current transformers condensers or induction
devices are encased in an insulated or insulating chamber or tube closed at both
ends with the terminal attachments arranged so as to provide for fitting in sockets
or vice versa or in close contact with the terminals of the accumulator or battery
and with the, terminals constituting the extension of the circuit in which the
working resistance is adapted to operate. This chamber is provided with a screw
or fitting portion or with one or more screw nuts or clamps or spring clips which
are adapted to fit and be secured to or with a part or extension or cap of the
chamber stand or casing of the accumulator through which the terminals therefrom
are led. This cap or casing can be screwed upon the main body of the chamber
when circular in form and I preferably interpose a vulcanized or elastic washer.
between such part or in some cases I secure the cap or cover as a lid with an
elastic washer between the parts and pass screw bolts through the lid and sides or
corners or outside of the body of the chambers through the base and thereby secure
the parts in position the casing or chamber containing the regulators or trans-
formers or both can be screwed or socketed into the lid or cap and the translating
device (for instance an electric lamp mounted upon its holder) with or without a
hand regulator or circuit closer can be mounted upon the socket or extension of the
chamber containing the regulator or upon the chamber enclosing the battery or
accumulator and secured in position thereon or therewith by a screw nut or
otherwise all as hereinafter more fully shewn by Figures 1 to 7 and the description
thereof. The chamber containing the elements of the accumulator may consist of
vulcanized material or Spence metal moulded into the desired form and provided
with the covering and clamping devices described a series of compartments can be
provided therein and the individual elements secured in each chamber with the
terminals single or compound extending through the single or compound lid as
described in the specification of my aforesaid application the elements can be
connected with the discharging or working circuit in any preferred manner.
The accompanying drawing and the following description thereof serve to make

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:-
My invention relates to improvements in portable electric apparatus for electric
lighting or other purpose provided with means for holding a reserve of electric

it will develop a pressure in the circuit higher than required for the lighting or

I employ electrical working resistance in the circuit which is adapted to operate

such for example as those herein set forth with reference to the drawings accom-
panying my provisional specification.
(b) In the construction or working of such apparatus I preferably employ a
battery or accumulator constructed as described in the Specification of my
application for Letters Patent N° 13879 of this date by which means I increase
the storage capacity, reduce the weight and bulk obviate short circuiting and
render practicable the charging of such battery with greater rapidity than is
otherwise practicable. For such rapid charging the battery or accumulator is
equipped with charging conductors and terminal plates or sockets of the same or
about the same conductivity as the electrodes or elements in the battery and
I provide also discharging conductors (which may either be independent of the
charging conductors or constitute branches thereof) of the necessary dimensions or

current to meet the requirements of the translating or transforming device or

controlling devices such for example as those hereinafter described with reference
to the Drawings accompanying my provisional specification.
(c) In the construction of such portable apparatus I arrange the secondary

passed through the main circuit or a loop or branch therefrom constituting for
example a solenoid the core of which is combined through a lever or otherwise
with such plunger or movable part constituting the variable resistance so as to
provide for the adjustment and desired variation of resistance. In some cases in
such combination I employ plungers or movable parts adapted to work within an

(e) In such portable apparatus I may employ in combination with the circuit
closer or pressure regulator as set forth a conducting liquid in the insulating or
insulated chamber. For instance I can employ mercury for this purpose and cover
the same with an insulating liquid such as paraffine glycerine or the like. Or
I sometimes provide for regulating the conductivity through the medium of
rubbing-contacts held in position by a spring or the equivalent thereof such for
example as is bereinafter described with reference to Figures 1, 2 and 3 of the
Drawings accompanying my provisional specification with or without the medium
of a non metallic liquid all of which are enclosed in a suitable casing or chamber
insulated or of insulating material and preferably arranged to form a completed
part with the terminals and sockets so as to provide for connection with the
elements of the accumulator or battery provided with fitting parts insulated the
extension of the circuit in which the working resistance is included being connected
therewith all as hereinafter more fully described with reference to Figures 1 to 7 of
the Drawings accompanying my provisional specification so as to constitute a self
contained or portable apparatus.
(f) The arrangement and operation of the various parts of such portable
apparatus is such that when the circuit from the battery is completed for lighting
or other purpose and the hand circuit maker or automatic pressure regulator is in
its normal position (in which position it may be held when the circuit is broken by
a spring or weight) only a small or minimum amount of current can pass into the

interposed in the circuit thereof to the battery as hereinafter described and
illustrated with respect to the parts L & J in the Drawings accompanying my
provisional specification.
(i) In combination with such arrangement of apparatus I employ means to
control or regulate the current passing into or through these condensers or induction
or transforming devices from the magazine or battery or accumulator by the
employment of an automatic pressure regulator as hereinafter more fully described
such device being automatically operated by the current passing through the dis-
charging circuit of the battery or through a loop therefrom so that in accordance
with the variation of resistance in such circuit so will the conductivity of the
circuit to the condensers induction or transforming devices be regulated or varied.
In portable apparatus as set forth the circuit or circuits of the transforming.or
induction devices can be combined with the circuits of the battery through a com-
mutating or switching device whose plungers or movable parts are adapted to
