The latest thing in slot machines is one that will take your photograph, develop it, and present it to you in a frame, with a pin attached to the back affixing it to a garment-all in just two minutes, by the watch. This is just now being, installed in every railroad station of importance and in other public places where a harvest of nickels is to be gathered. In order to have your picture taken, you drop a nickel in the slot and then detach from the machine a handle, which retains connection with the apparatus by a wire. Then you sit down in a chair, still holding the handle, and observe yourself in a small mirror placed for that purpose in front of the machine. When you have the proper attitude and expression you press a button in the handle, and immediately a brilliant electric light is flashed upon you. At the same time a bell rings, and continues to ring while the exposure lasts. The exposure is only about two seconds, during which, of course, you are expected to remain perfectly still. You may then get up from the chair and relinquish the handle, inasmuch as the machine will do the rest. The plate which has been exposed is automatically immersed in a developing bath, where it remains for five seconds. Out of this it slides into a fixing bath, where it lies for 25 seconds. Then it goes into a chemical wash for a few more seconds, and, emerging therefrom, is almost instantly presented to you, framed as aforesaid, and with a pin at the back. Of course, the plate is developed not as a negative, but as a positive. Furthermore, it is already contained in its little frame, with a pin attached, when it is put into the machine. Hence no time is lost supplying the frame with the portrait, and the latter is produced complete inside of two minutes. The chemical wash which succeeds the fixing bath is, of necessity, a prompt drier. This novelty is the invention of a Cleveland, Ohio, genius. The price of the pictures is a nickel each.
