A Full Horizon in Motion

like that of a fine watch giving synchronized function to all working parts although sprockets advanced the film at constant speeds the flow of film past the light source must be interrupted otherwise we would see not motion picture but motion blur to prevent this we need a device called a shuttle which reaches into the film and pulls down one frame at a time obviously a poorly designed shuttle can cause film damage however the Bell & Howell shuttle is a precision components made from stellite one of the hardest alloys known it's a very expensive part but Bell and Howells commitment to design integrity and film protection demand its use moreover Bell & Howell is the only major projector to have a shuttle with free teeth instead of the usual two in the event of torn perforations it's the job of a shuttle to reach up and pull down the good perforations of the film three teeth obviously have a 50% better chance of recovering good perforations than due to of prime importance in safe film handling is the loop restorer and Bell & Howell has one of the best loop restores on the market loops are needed to provide a supply of film so the shuttle can operate independently from the sprockets when film starts to chatter it means that the shuttle has encountered torn sprocket holes although the shuttle strokes the film is not transported and the lower sprocket removes the lower loop the loop restore must recover this loop restore balance to the system and eliminate film blur on the screen if however the loop restore pulls while the shuttle is engaging good film the only result can be further damage only Bell & Howell and its autoload brand and manuel/oh 1579 models avoids this problem by synchronizing the shuttle and the loop restore the loop restore operates only when the shuttle is pulled back out of contact with the film some other user benefits common to Bell & Howell projectors are a plug-in solid-state amplifier for ease of service and permanent lubrication of the mechanism convenient precise rack and pinion focusing by the turning of a knob not the barrel of the lens a product designed for every need and for every choice Bell & Howell can proudly claim that it has the fullest line of dependable high quality 16 millimeter projectors the best in automatic load and manual load projectors by far the biggest percentage of users prefer the convenience and efficiency of the auto load projectors but there is a considerable number of people who like to do things themselves for those people Bell & Howell has added a new member to the family a manual load with the utmost convenience the new slot threading model 1580 given the choice what design features what they want in this type of projector we didn't assume we went out to test it functionally and here is some 8 millimeter footage of testing activity we called in teachers and audio-visual directors but we also drafted people off the street housewives businessmen kids we had both the pros and the amateurs operate the 1580 themselves as well as other projectors we recorded our observations and determine where they had difficulties we time them interview them found out with a light and what they didn't like later we redesigned the 1580 based on the testing results and then went back and tested again as a result of the field tests all instructions and labels have been extremely simplified indicated according to function as the user would think of the function someone who has never operated a 16-millimeter projector can run the 1580 without a word said to him the operation is simplicity itself as simple in fact as one-two-three just follow the big numbers swing the lever down to position one take the end of the film and pull it under position two all the way around the groove attach the film to the rear reel bring the lever up to position three the loops are set the gates are closed it's ready to go the main control tells it exactly as it is you simply turn the control to project film chatter is unlikely to occur in the 1580 unless the film is in pretty bad shape but if it does happen a touch of the loop reset and it's right back in business and here's another great feature if you want to show only part of a film there's no problem with this easy to operate manual load machine just flip the lever down to position one and the gate opens slip the film out of the film pad raise the rear reel arm and rewind the high-speed clutch is built into the reel arm so it automatically goes to high speed rewind the new Bell & Howell easy slot threading projector has joined a proud family the fullest line of 16 millimeter projectors on the market including the high intensity projectors 566 and 567 the unchallenged leaders for auditorium use and the 561 in 562 film chain projectors the best buy on the market for that purpose a full line where every feature of every model has been designed and oriented towards user benefit the conventional manual load 1579 to meet the needs of those who demand a manual load with all the basic Bell & Howell quality features at a budget price the low-priced auto load 1585 which is found in more classrooms around the country than any other 16 millimeter projector the lightest auto load projector the 1590 in addition to its ability to meet every film projection need it's light weight makes it a great rental unit and the choice of those who want the very best in 16 millimeter projectors is the bell & howell autoload 1592 we produce the first automatic threading projector in the film world and we still produce the best the 1592 still handles film better than any other Bell & Howell auto loads are still the easiest to operate simply trim the end of the film engage the auto load mechanism turn on the projector and feed the film into the film path the results of the field tests we conducted on the new 1580 have also improved the design of the auto load projectors the easy to handle controls have clear functional labels the 1592 lets you stop the motion and view a single frame of the film the control is a convenient lever located as a separate functional unit at the top of the projector and for those who want to show sequential action frame-by-frame there is the direct emotion feature another result of the field testing was to provide our two top auto load models with a hinged lamp access door made of tough Norrell plastic changing a lamp now becomes a very simple task it all makes sense first discover the desires and the needs of people who actually will use motion picture projectors then integrate the design to meet those needs reliability safe film handling good picture quality convenience and simplicity of operation and then offer the choice a full horizon in motion from Bell & Howell [Music]
