Improvements in Apparatus for use in the Manufacture of.
Accumulator-plates.
CARL MARSCHNER, of Rosenstrasse 105-107, Dresden, in the Empire of Germany,
Electrician, 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 improvements in apparatus for perforating accumulator
plates, whereby it is rendered possible to effect the scraping off or removal of the
adhering mass from the perforating pins as they are withdrawn from the material.
This result is attained by the combined action of a press-plate with the plate carrying
the perforating pins.
In the accompanying drawing, Fig. 1 shows by way of example, a press with a device
according to the present invention in longitudinal section.
Fig. 2 is an under side view of the perforating plate.
Figs. 3 and 4 are respectively a longitudinal section and a cross section of the
perforating and scraping off device after the pins have been inserted into the
material.
The compressing and perforating of the plates is effected by means of the usual
presses, driven in any desired way. The movable part B of the press serves to receive
frames a filled with the mass to form the plates and to be perforated.
The device for perforating and removing the material is arranged on the fixed cross
frame A of the press. To its bottom plate e is secured a plate ƒ provided with
perforating pins l. A press plate h provided with holes corresponding to the pins lis
connected to the plate ƒ by means of volute-or other springs g and is guided by
means of rods i on the plate f passing through holes in the plate h.
The operation is as follows;-
When the plate a placed on the slide is placed on the table B of the press and said
table begins to move upwards the press-plate h comes first into operation by coming
in contact with the plate forming mass and slightly compressing it.
During the continued ascent of the table the press-plate his moved towards the
perforating plate f. The pins thereupon come out through the holes in the
press plate h and penetrate into the mass until the end of the stroke (Fig. 4). During
this time the springs g become strongly compressed.
When the table begins to descend these springs become operative and the pins are
drawn out of the mass. But as the press plate h follows the table in its movement
owing to the action of the springs g it scrapes off and removes the mass adhering to
the pins l.
At the movement when the lower end of the needles is on the same
level as the lower surface of the press-plate h, the plates are completely perforated and
may be removed from the perforating device.
Owing to this connection of the plate f with the press plate h perfectly clean
perforation of the plates is ensured.
Having now particularly described and
ascertained the nature
of this
invention and in what manner the same is to be performed I declare that what I
claim is:

page_text: 1. Apparatus for perforating accumulator plates and removing adhering material
from the perforating pins comprising a press plate h provided with holes through
which the perforating pins on a foundation plate may pass in such way that when the
perforating operating is finished the press-plate his flush with the perforating pins
and is withdrawn from the perforated plate together with the pins so as to avoid the
formation of burrs or irregularities when the pins are being withdrawn substantially
as described.
2. In apparatus of the character described the arrangement of springs of any
desired kind between the perforating plate f and press plate h substantially as and
for the purpose described.
3. The combination and arrangement of parts constituting the complete apparatus
for use in perforating accumulator plates substantially as described and illustrated in
the accompanying drawings.
Dated this 30th day of December 1897.
