page_text: Date of Application, 28th Feb., 1898-Accepted, 23rd July, 1898
I, J. ENSIGN FULLER, of 11, Warren Street, in the City, County and State of New
York, United States of America, President of Manufacturing Corporation, 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 apparatus for generating electricity, and particularly to
primary batteries, and the object thereof is to provide an improved device of this
class which simple in construction, and effective and durable in operation, and
which may be employed wherever such generators are applicable, and which is
particularly adapted for use in connection with light machinery, incandescent or glow
lamps and for other and similar purposes.
A further object of this invention is to provide an improved primary battery in
which the life of any strong battery solution may be prolonged by separating the
zines from the solution when the battery is not in use and sealing the solution in
separate cells by itself, so as to prevent said solution or the vapors therefrom from
continuing to decompose the zines, the battery being inverted when the operation of
separating the solution from the zine is performed; and with these and other objects
in view, the invention consists in the construction, combination and arrangement of
parts hereinafter described and claimed.
In the operation of strong acid battery solution, the life of the solution may be
prolonged hy separating the zines, and the solution when the battery is not in use,
as above described, and also by such constant agitation as will continually change
those portions of the solution which come in contact with the poles of the battery
when the latter is in use, and by churning or agitating said solution, thus retain the
proper combination of the ingredients composing the same.
One of the chief objects of this invention consists in providing a mechanical device
for agitating or churning the solution, and by means of which the hydrogen bubbles
which adhere to and insulate the poles in batteries of the class as usually constructed,
are prevented from collecting on said poles, and the formation of what is called
chrome-alum is also prevented.
It has been found that in bicycles and carriage lamps primary batteries capable of
operating a small candle power electric lamp will lose their power in two or three
hours even though considerable agitation is brought about by the motion of the
vehicle, but this motion, however, is not steady, and is generally more in the nature
of a tremor and does not churn or agitate the liquids or solutions sufficiently, and
one of the objects of this invention, therefore, is the production of batteries wherein
the tendency of the battery solutions to disintegrate under electric and chemical
action is largely counteracted by means hereinafter described, and wherein the
properly prepared exciting fluid is constantly presenting new contact portions to the
surfaces of the poles thus obtaining the full electric discharge of which the battery is
capable, and a far greater number of "light hours," and a further object of the
invention being to provide a simple, cheap and effective apparatus which forms a
part of the battery, by which all possible action of the solution is terminated by
sealing the cells when not in use, until the light or power is again required.

page_text: In lamps such as bicycle and carriage lamps operated by electric solution batteries
it has been necessary to empty out the partly used solution as soon as the destination
is reached, no matter how short the ride, for the reason that although the acid
solution may be thrown away from the zines, by turning the battery upside down
and actual contact with them terminated, still if the solution is left in the battery
cells, the acid vapor rising from the solution will keep up the decomposition of the
zines so that such batteries have to be replenished completely before being used again
and in all primary battery work, no adequate provision has been made to completely
seal the acid from the zincs, and preserve its strength.
The invention is particularly adapted for use in connection with lamps for watchmen,
carriages, bicycles and similar vehicles; and said invention is fully disclosed in the
following Specification of which the accompanying drawing forms a part, in which
the separate parts of the invention are designated by the same letters of reference in
each of the views, and in which ;-

showing the supports therefor.
In recently invented batteries as well as in older styles, the cells have been made
gas or vapor tight to keep the fluid from evaporating rapidly, and diminutive vents
have been inserted or provided to prevent the accumulation of two great pressure,
but these vents are necessarily not closed after the fluids and zines are separated,
because the chemical action is not stopped, consequently the fluid goes on evaporating
to the outside air and becomes weaker very fast.
In the improved battery, the fluid is not only sealed away from the zincs when the
battery is not in use, but the vent is contained in the closing rod and sealing stopper
which is employed, and when the fluid is thrown into the storage compartments, which
forms a part of the battery to separate it from the zines, and the compartments are
closed, said compartments have no egress to the outer air but are air tight, while the
moisture left clinging to the zines in the working cells may be evaporated to the outer
air, and thus dry said zines quickly.
In the construction of the improved battery there is first provided a casing A,
which is composed of, or molded froin, rubber or a composition of rubber and other
suitable material, or aluminium coated with acid proof and insulating enamel may be
employed; and said casing is provided with vertical partitions a formed integrally
therewith, two of these partitions being shown in the drawing, the battery shown in
the drawing being a three cell battery.
The three separate compartments formed by the vertical partitions a, are divided
centrally and transversely by partition plates a² which are placed upon ledges or
shoulders forined by vertical strips a³ secured to the walls of the casing, and to the
partitions as shown and these partition plates are preferably composed of the same
material as the casing, and by means thereof three separate storage compartments a*
are formed and also three cells a5.
The partition plates a², are intended to separate the cells a³, from the storage
compartiments a', and the partition plates a project downwardly preferably below the
bottom of the sides of the casing, and the compartments at are closed by caps or
covers H, which are also secured against ledges or shoulders formed by vertical
strips secured to the inner walls of the casing, and to the partition plates, and
inserted after the horizontal partitions are adjusted and sealed in place.

page_text: It is evident that this end of the battery may be closed in moulding the casing A,
and the opposite end closed by caps, or similar caps may be used on the upper ends of
the cells also, instead of having those ends as a part of casing A.
The positive poles of the battery are shown at B and are preferably tubular in form,
and as shown are perforated or provided with slots b, to permit of the free passage of
the battery solution therethrough, and these slots or openings 6 are formed in the
sides and upper ends of the carbons or poles B, or said positive poles may consist of
separate parts as will be readily understood.
Arranged centrally of the tubular carbons B, and passed through openings in the
top of the casing above each cell a are the zincs D, which are cylindrical in form, and
each of these zines is provided with a screw threaded bolt d, which is screwed thereinto
and on which is mounted a flat rubber cylindrical packing 2, and said bolt is provided
with a milled head or nut C, in which is formed an annular groove, C2, and between
the head C, each of said screw threaded bolts, and the rubber packing d², is placed a
washer d³, which is preferably greater in diameter than the said head C, and the
opening in the casing top.
The invention, however, is not limited to this exact form of construction for
connecting the zincs D, with the rod or bolt d and for closing the openings through
which they pass, and any suitable means may be provided for this purpose.
Upon the top of the casing is secured, over the right hand cell a³, as shown in
Figs. 1 and 3, an annular spring arm E pivoted thereto and adapted to turn thereon
to engage with the groove C2, in the milled head C of the zinc, which passes into said
right hand cell, and at the opposite side of said zinc is a similar spring arm E2,
adapted to engage with the milled head of the zincs of the middle cell, and at the
opposite side of the said middle zine is a third spring arm E³, engaging in like
manner the milled head of the zinc of the left hand cell."
The tubular carbons or poles B, are connected with the casing top, over their
respective cells, by screws F, which are passed through said caps and into holes formed
in the upper end of said tubular carbons or poles, and said carbons or poles, where the
screws Fenter, are enlarged or thickened as clearly shown in Fig. 2, and between the
upper ends of said carbons or poles and said casing top, are placed soft rubber packing
rings 8, and by means of the screws F, the carbons or poles B are drawn tightly
against the casing, and the said rubber packing prevents the battery fluid or solution
from coming in contact with said screws.
Connected with one of the screws by which the carbon or pole B of the left hand cell
is secured to the casing, is a wire or conductor f, which is connected with the screw
threaded socket. of an incandescent electric light f as shown in Fig. 1, or with a binding
post f³ as shown in Fig. 3, and the zinc of the first or left hand cell is connected with
the spring contact arm E3, by means of the head C, of the bolt. d, in said zine, and
said contact arm is connected with one of the screws by which the carbon or positive
pole of the middle battery is secured to the casing, by means of a wire f* as shown in
Fig. 1; and the zinc of the second or middle cell is electrically connected in the same
manner with the carbon in the third or right hand cell by the spring arm E2 and the
wire ; and the zinc of the third or right hand cell is connected with the spring
arın E, with which is connected a wire which is also connected with the head of the
incandescent electric lamp 2 as shown in Fig. 1, or with a binding post as shown in
Fig. 3.
The casing A, as shown in Fig. 1, is provided with an ordinary reflector G, in
which the incandescent lamp is placed, and in Figs. 3 and 4, I have shown
two binding posts f³ and fi with which the wires f and f6, are connected, and
these binding posts may be used for any desired purpose.
The partition plates which separate the compartiments a from the cells as, are
secured in place in any desired manner, and each is provided with a central enlarge-
ment or depending extension a" having a central conical opening at g, the base of
which is directed downwardly, and each of the cells is provided with a small curved
vent tube g², one end of which is passed through the corresponding plate a², and
terminates in an aperture ³ in the top of the partition a² ranging diagonally there-

page_text: through into one side of the central conical opening g. The bottom of each
compartment is provided with a central opening gt, and passing through each of
the openings g is a short shaft g³ the upper end of which is conical and adapted to
enter the corresponding conical aperture g, and these shafts g are composed of
rubber or similar material, and each is formed at its upper end into a valve g which
is adapted to close the communication between the cell as and the storage compart-
ment at. In the drawings I have shown these shafts provided with ports g7 ranging
from the upper ends thereof downwardly and laterally and opening into ports alo
formed in the side of the partition enlargement a" opposite the aperture 3³ therein,
and said shafts are also provided with ports g³ communicating with the aperture 3
and ranging downwardly to the lower edge of the valve portion g of the shaft,
whereby in the position shown in the drawing, when the main passage is open
between the cell and the storage compartment, the vent g2 also communicates with
the latter at the same time and both are simultaneously closed by turning the
shaft g. These shafts are each provided with a longitudinal passage or vent yo
reinforced at top by a tube glo.
In the lower or open ends of the compartments at are inserted caps or covers H,
forming the base or closure of the casing and bearing against the vertical strips a7.
These caps are centrally apertured to receive the shafts g5 therethrough, being
provided thereat with annular flanges extending outwardly or downwardly and
internally threaded, and said caps being provided with annular inwardly ranging
flanges h¹ fitting closely around the shafts 5. Upon the shafts, within the flanges h,
are secured collars h² and packing rings h³, against which bear externally threaded
caps h which screw into the flanges h, and surround the shafts g5. Mounted upon
the ends of the shafts are gear wheels I, meshing one with the other, and secured in
place by screw caps i, the shanks of which enter the shafts and are apertured in
alignment with the vents therein, and the heads of which caps are recessed to receive
therein a flexible rubber diaphragm which is provided with a minute central
puncture which when the diaphragın is expanded or forced outwardly, opens to permit
the escape of gases through the vents in the shafts, said diaphragm being secured in
position by flanged disks 22, screwed into the heads of the caps i, with rubber
washers between the same and the diaphragms, said disk being provided with
apertures 4, forming outlets for the gases escaping through the diaphragms.
The central shaft g5 is provided with a milled hand wheel J in addition to the gear
wheel I, by turning which hand wheel all of the shafts are simultaneously operated.
As will be readily understood, the normal position of the battery when not in use
is that shown in Figs. 1, and 2, in which position the battery fluid is confined in
the storage compartments and sealed therein, and neither said fluid, nor the fumes
therefrom, can come in contact with the zincs D, and whenever it is desired to put
the battery in operation, it is inverted, and the wheel J is turned to the left, and
this operation opens the ports or passages 97 and a10, and the fluid passes into the
cells, the battery being inverted for this purpose. The vent tubes g², it will be
noted, are opened at the same movement and permit the passage from the storage
compartiments or the cell (according to which is being filled) of the air displaced by
the entrance of the acid.
In the operation of the device, the longitudinal vents gs through the shafts serve
to allow the fumes arising from the battery fluid to escape, thus preventing the
swelling or bursting of the battery casing.
It will also be understood that the invention is not limited to the material of
which the various parts of the battery herein shown and described, are composed,
and the best material for this purpose may be selected.
In practice, the heads C, of the bolts d are screwed down, so that the washers d
press firmly upon the casing, and in this operation the soft rubber packing d2 is
compressed so as to tightly close the openings in the casing, and the washers d³ rest
on said cap plates. For filling or charging the battery, the battery fluid or solution
is furnished in bottles or receptacles which are marked off on the label showing just
how much to put in each cell, and the stoppers or cell closers, which consist of the

page_text: valves g, being pressed into the openings in the partition plates, the fluid is poured
in through the central openings in the casing, and the zincs D, are then placed in
position, the knobs C, are turned to the right and cells 5 are firmly sealed so that no
liquid or vapor can escape through the casing, when the battery is in the inverted
position and in operation; it being understood that by turning the movable knobs C,
on the bolts or screws d to the left, the rubber packing d2 will contract so that the
zines may be drawn out, and in this operation the spring arms E, E, and E must be
turned so that they will not engage with the knobs or heads C, of said bolts, and said
spring arms may be turned back again into position after the zines have been secured
in place as described.
When the cell is in the position shown in Figs. 3 and 4, and the battery is in
operation, the shafts g5 may be operated or turned so as to slightly open
the ports or passages in the partition plates a², but this is not essential to the
operation of the battery, and whenever it is desired to stop the operation of the
battery, said battery is inverted, and the shafts are turned so that the battery
fluid will flow out of the cells into the storage compartiments at, as hereinbefore
described, and it will thus be seen that when the battery is not in use, the battery
fluid does not come in contact with the zines, and there is not waste or consumption
of the latter.
It will be apparent that this improved battery may be used wherever such
devices are applicable, but in Figs. 3 to 5, inclusive, is shown the method of
applying the battery to a bicycle or similar vehicle, for the purpose of operating
an incandescent or glow lamp, and in this application of the improvement there
are provided means for quickly inverting and for agitating or shaking the battery
and the battery fluid when the battery is in operation, the object of this construction
being herein before set out.
For this purpose there is secured to the side of the casing A of the battery, a
pivoted arm M, to which are attached spiral springs m, and secured to the upper
ends of these springs is a cross plate m² centrally of which is secured a supplemental
spiral spring m³, and to the spring m³ is secured a cross bar m', which is provided
on its upper surface with a longitudinal groove m³, and the cross bar m² is provided
with transverse slots or openings me through which are passed straps m² by means
of which the battery may be connected with the upper horizontal rod m³ of a
bicycle frame.
any
The binding posts f³ and f' serve as attachments for wires or conductors O, and
connected with the upper part of the forward portion of the frame of the bicycle is a
clamp 02 which is provided with an arm 08, to which is secured, in desired
manner, a reflector 0, in which is placed an ordinary incandescent or glow lamp,
which is not shown, and said reflector 0+ may be provided with a backwardly directed
tubular attachment 05 in which may be placed a glass by means of which the light
may be seen from the rear of the vehicle.
In the construction shown in Fig. 5, the spring m³ is omitted, but the operation
will be substantially the same in both cases, and by means of the springs m, and the
springs m³, when the latter is employed, the battery will be kept in a constant state
of agitation as will also the battery fluid therein, and the life of said battery may
thus be prolonged as hereinbefore described, and other forms of springs may be
employed.
In Fig. 6 are shown devices for supporting the improved battery on a carriage or
other vehicle and these devices consist of a brace or other suitable support R, on
which is mounted a spiral spring R2, on which is placed a fraine R³, by means of
which the battery may be supported, and by reason of the spring R2, the battery will
be constantly agitated or shaken when the vehicle is in notion, and this agitating or
shaking of the battery will result in agitating or shaking the battery fluid as will be
readily understood, and the result of this operation will be the saine
herein before described with reference to the construction shown in Figs. 3 to 6,
inclusive.
as that

page_text: This mode of supporting the battery permits of its being inverted by a turn of the
hand to either light or extinguish the lanp, and if but temporarily extinguished the
passages or valves need not be closed. The invention broadly involved in this
battery, and the new technical effects or principles embodied therein, are the vertically
aligned divided cell and storage compartment comprised in an invertible battery,
whereby the cell is the lower chamber when in use and the storage compartment
when not in use, and means for opening and closing the communication of the two
chambers to shut off action of the battery and at the same time prolong the life of
the fluid; and secondarily the divided cell and storage compartment vertically
aligned as aforesaid comprised in a battery pivoted to make a semi-revolution by a
turn of the hand; thirdly, the device as described, embodying both fluid passages
and air vents opened and closed at the same time, by the valve, so that the cells will
quickly empty into the storage compartment or vice versu; and finally such a device
mounted in the spring vibrating holder to be shaken or agitated to prolong the life
of the fluid and produce a decidedly more efficient battery than has heretofore been
constructed.
The improvement is not limited to the exact form, construction and arrangement
of the various parts thereof as herein shown and described, and it will be apparent
that changes therein, and modifications thereof, may be made without departing
from the spirit of the invention or sacrificing its advantages.
