Show An ingenious new lamp Is now being shown in St. Louis, the merit claimed for which is that the danger of oil overflow over-flow in filling is averted. This is done by means of a piece of glass of prism shape Inserted ill the top of the reservoir reser-voir and with one portion extending down into the oil space. Thus it is possible pos-sible to tell as soon as the oil reaches the lower part of the glass extension and the exact level of the oil can be seen and; followed! as it rises toward the inlet through which the lamp is being filled. |
