of arranging the zinc cylinder 14 directly on
the ring-support 13 it will be obvious that
such cylinder can be readily removed and re-
placed, and besides serving to properly sup-
5 port the zinc cylinder 14 within the cell the
said ring-support 13 provides for properly po-
sitioningtheporousbattery-cup 15. The por-
ous battery-cup 15 is of an ordinaryform and
subserves its usual function, but in the pres-
io ent invention the lower closed end of said
battery-cup rests directly on the bottom of
the cell and is disposed inside of the ring-sup-
port 13 for the zinc cylinder or positive ele-
ment of the battery, thereby providing an
15 arrangement which insures the proper posi-
tioning of the porous cup 15 in the center of
the cell.
In order to provide for the completion of
the electric circuit with the zinc cylinder or
20 positive element 14 of each cell, the copper
ring-support 11 in the cell has suitably con-
nected to one of the peripheral supporting
feet or lugs 12 thereof the lower end of an up-
right conductor-rod 16, which extends up the
25 entire height of the cell and the upper end of
which is designed to project through the cover
3 and centrally into a tapered opening 18,
formed in a metallic corner-plate 19, fitted to
the upper side of the cover 3, and said upper
;o end of rod 16 is designed to be detachably en-
gaged bya connecting-plug20. The connect-
ing-plug 20 essentially consist of a thumb-
head 21 and a tubular tapered shank 22, work-
ing within the tapered opening 18S of the plate
35 19 over the upper end of conductor-rod 16.
The said tubular tapered shank 22 of the plug
20 is provided with a series of longitudinal
slits 23 and an outwardly-flared lower end 24,
which latter part of the plug prevents its with-
40 drawal from the opening 18 and also assists
in guiding the upper end of rod 16 within the
tubular shank of the plug. This plug when
forced down onto the upper end of rod 16 and
within the opening 18 completes a direct me-
45 tallic connection between the zinc cylinder or
positive element 14 and the plate 19, with
which plate suitable wire connections are de-
signed to be made in any suitable manner.
By reason of preferably employing a group of
50 four cells within the case or box it will be ob-
served that the plate 19 for each of the cells
is secured to the cover at one of the corners
thereof, so the said cover is illustrated as be-
ing provided with a corner-plate 19 at each of
55 its four corners.
Each cell of the battery is completed by a
carbon pencil or negative element 25, which
is substantially of the same length as the por-
ous"cup 15 within the cell, and is disposed cen-
60o trally within such porous cup. The carbon
pencil 25 for each cell extends at its upper
end through an opening 26, formed within
the cover 3, and is detachably clamped with-
in a split clamp-ring 27, arranged on top of
65 the cover 3. The split clamp-ring 27 is pro-
vided with a series of offstanding screw-eyes
28 to receive fastening-screws 29 for fasten-ing the clamp-ring to the outer side of the
cover, and said ring is further provided at its
contiguous ends with the parallel clamp-lugs 70
30, which receive the clamp-screw 31 for tight-
ening and loosening the clamp-ring on the
upper extremity of the carbon pencil to pro-
vide for the ready removal and replacing
thereof when necessary. In connection with 75
the several carbon pencils carried by the cover
3 it is to be noted that the wires arranged in
the wire-grooves 5 of the cover are suitably
connected therewith and are arranged in a
suitable manner to provide for completing the 80
proper circuit with the corner-plates 19, as
will be readily understood by those skilled in
the art.
The wire-receiving grooves 5 are plainly
illustrated in the sectional view of Fig. 3 of 85
the drawings, but to illustrate the manner of
arranging these grooves when the cells of the
battery are wired in series the proper circuit
connections are indicated in dotted lines on
Fig. 1 of the drawings, it of course being un- 90
derstood that the wire-receiving grooves 5 fol-
low the disposition of the wires therein. In
connection with the wiring of the cells, as
illustrated in Fig. 1 of the drawings, the case-
cover 3 has fitted thereto a pair of ordinary 95
binding- posts 40, respectively having the
wires a and b connected therewith. The ter-
minal of the wire a opposite its connection
with the binding-post 40 is connected with
the metallic clamp-ring 27 for an adjacent ioo
carbon pencil 25, while the terminal of the
wire b opposite the binding-post 40,with which
it is connected, is connected with an adja-
cent metallic corner-plate 19. To complete
the proper series connection between the cells, o05
a series of circuit-wires c are employed, each
wire c being connected at one terminal to the
metallic clamp for the carbon pencil of one
cell and at its other terminal with the metal-
lic corner-plate 19 for the next adjacent cell. Iio
A soft-rubber absorption pan or tray 32 is
adapted to be arranged within the upper end
of the case or box 1, directlyon top of the cells
2 therein, so that when the cover 3 is fas-
tened in place on top of the pan or tray 32 115
the open upper end of the cells 2 will be cov-
ered in a perfectly air-tight joint. The pan
32 is provided over each of the cells 2 with a
series of vent-openings 33 and is designed to
be filled with a suitable absorbent packing 120
34, preferably moistened with soda or com-
mon water, so as to absorb and neutralize the
fumes liberated by the chemical action with-
in each cell and which rise through the vent-
openings 33. The pan 32 is partitioned by 125
the partition-strips 35, so as to be provided
with a separate section for each of the cells,
and each section of the pan or tray is pro-
vided therein with a pencil-opening 36 to re-
ceive the carbon or negative element of the 130
cell.
From the foregoing it is thought that the
construction and many advantages of the
herein-described primary battery will be read-
