Those interested in semi-portable projectors of high quality may secure copies of the booklets by addressing the Graphoscope Co., 712 Eleventh street, N. W., Washington, D. C. Another Change-Over Signal Mr. M. A. Godwin, Bridgewater, Mass., encloses a copy of the patent specification covering a " film indicator " patented by him and writes as follows : " I am enclosing a copy of my Patent Xo. 1,233,868 for a Film Indicator. Inquiries regarding same were called to my attention in the January 19, 1918, issue of the Motion* Picture News. The enclosed copy will answer all questions and perhaps be of interest to you. This indicator has been in successful operation at the local picture house since December, 1916, when application was made for the patent." Comment: It will be seen from the appended diagrams, reproduced from Mr. Godwin's patent specification, that his changeover signal, or film indicator as he terms it, follows the basic idea of most similar devices, i. e., it is operated by a hinged or pivoted arm terminating in a roller which bears on the circumference of the film reel; the position of the arm changing as the diameter of the film roll decreases and a pointer attached to the pivoted end indicating the proper time to prepare the second machine for changing over. The Godwin Film Indicator Mr. Godwin's device is, perhaps, the simplest of all the changeover devices embodying this principle which has been described to date, and therefore will probably not accomplish all that some other devices will, such, for instance, as the J. K. & E. Indicator, described in the News of January 19, 1918 (the issue alluded to in Mr. Godwin's letter). That device, it will be recalled, rings a bell at any desired distance from the end of the reel, in addition to showing how much film has been projected by means of a pointer and dial. While Mr. Godwin's letter and patent specification do not state how the device is to be adapted to use with reels having various W A A B ELLS IMPLEX *yfiT Machines, Minusa Gold Fibre A Screens, Speer Carbons, Wertsner's J\_ Silver Screen, Swaab's Motor Equip Ament for Power 6 A and all supplies for Theatre equipment.
