Cne o the simplest and must effect-ive effect-ive devices invented for the purpos if auioaiaUcally registering the- entry nd departure of employe In kry establish:. .e:As is the photographic ar-rangerae-nt described in La Scieucs Prancalse.- The instrument is bote 3Wft and autnrpatlc. and. from the fad that it combines the cinematograph and the chronometer, it certainly maj , id tn be "up to date." The appa- ratus, .which is a rectangular box hav-, ing an object lens in front and a j glazed panel on top, photographs tht j lace of the person who stands befon the lens by means of a novel but ex-1 trenieiy simple arrangement, at the i same times includes in the picture th dial of a ciock inside the box. Thus when the sensitive film is developed there is seen just under the employe's face the hour at which he reached th factory or left it. Instead of signins a time sheet or receiving a time card the employe, whoever he may be, hai only to turn his face toward the apparatus ap-paratus and press the button. Nothing Noth-ing can be simpler. There is no mistake mis-take and can be no possible argument The operation is instantaneous; th( constructor has shown by precise experiments ex-periments that each of his instrument! can register about fifty entries a minute min-ute As In the cinematograph, th dm unrolls automatically before th objective; but after each individual pose which lasts about half a second the shutter works at the pressure ol a button. A small electric bulb ii the apparatus enables it to be used a) night. The clock has a black dial on which the day of the week, the houri and the minutes, in white, and ovei which move two pointers of whit enameled aluminium. Although the price of the apparatus is relativelj high it costs incomparably less thai a time-keeper of flesh .and blood, whili guaranteeing much greater impartial, ity and exactness. New York Press |
