IMPROVED SAMSON CELLS.

The Samson battery, one of the oldest and most prominent open-circuit cells, has recently been changed, as shown by the accompanying illustrations. These changes, which have made a great improvement in the battery, have been mainly mechanical. The carbon connection, which, should occasion require, could not be renewed in the old style, is now made removable, and is larger and stronger and tinned to prevent corrosion. The carbon, of French production, is hollow and filled with a depolarizing compound, as shown in Fig. 1. It is made with a screw-top, which fastens securely into a threaded cover.

Improved Samson Cell.

The zinc has also been changed, and now has three projections at the top, which fit into a groove in the cover, and is held firmly in place against it by a large knurled nut placed on the zinc stem. This arrangement admits of placing the elements in position before shipping, and the only necessary handling after taking the cell from the packing-case is to remove the excelsior from around the elements and replace them in the jar, after having first added the sal-ammoniac solution. The rubber plugs and bands used in the old style, which collected the salts formed during action and were liable to allow a short circuit to be made between the elements if care were not used, are thus dispensed with. The battery is made by the Electric Gas Lighting Company, of Boston, Mass.
