Description

:: ί 1

You have it with today's composition of dry elements has always been a deficiency felt that after the electricity-generating parts have been consumed, everything is worthless and is thrown away. In addition, there is still more efficient use of the drying elements the fact that in the manufacturing cost the expenses for manual labor the value of the active ingredients (usually graphite, Brownstone. Zinc and electrolyte). Purpose of the present invention it is now, the consumable components in an easily replaceable and to produce the cheapest possible composition, while all other parts always can be used again. On the accompanying drawing represents

Fig. Χ the new element in vertical section.

FIG. 2 shows a cross section according to AB of FIG. 1 represents.

ßraunstein-zinc element. The element consists from two parts: r. the real one

2. the container with contacts (parts g to /> i.

While with the current elements a

A carbon rod surrounded by a mixture of manganese dioxide and graphite, wrapped in canvas or paper and tied with string forms the positive electrode, the production of which, as well as inserting it into a zinc cylinder and filling the gap with the stiffened electrolyte or the electrolyte absorbed by porous mass, is a laborious process and requires precise manual work, a carbon plate a is used in the new element, which is located in a cardboard frame b open on both sides. The graphite-manganese dioxide mass C is now pressed against the carbon plate from both sides t , which can be done very easily by machine, and a permeable cardboard if pressed in the form of a flat bowl serves as a closure for the manganese dioxide-graphite mass on both sides, which stiffens it Electrolyte e absorbs. The negative pole is formed by a bowl-shaped zinc plate f, which grips with the bent edges over the cardboard frame h and closes the whole thing firmly. Only the edges need to be sealed with asphalt, paraffin or the like. .

This element is now in a wooden box g, the lid of which is in a brass strip h with pole terminal i and brass 5; sleeve k an adjusting screw / carries. At the lower end, which is carefully varnished to protect against rising damp, a carefully paraffinized graphite pencil m is embedded in this adjusting screw (which can also be replaced by a small platinum tip), which is firmly attached to the carbon plate through a hole η in the cardboard sleeve α is seated and thus establishes a good connection with the pole terminal /. At the bottom of the wooden box an Ö5 brass sheet u is attached, which is connected to the pole terminal p . If the element is now placed in the box —1-5, of course, several can easily be made; such elements in a iremoinsanu-n box
