The friction gravity shutter responds im mediately to the slightest motion of the gears. It has been necessary with other shutters to run the machine at a very high speed before the safety shutter would raise and likewise necessary to bring the ma- chine almost to a standstill before the shut- ter would drop into place again. Among the 100 features claimed by the maker are: Best material obtainable used; metal, nothing but metal, except mica, fiber and (no wood whatsoever) asbestos used for insulation and handles, etc. The light weight, and yet strong—most parts made of steel alumium. The small space it takes when set up, the small space when packed up. The short time it takes to set up and to take it apart after the show; five minutes will set up the machine complete for cal- cium. The easy way to" operate it; a novice will understand it in fifteen minutes. The new one-rod lamphouse slide rest, dispensing entirely with a long table. An entire, new idea of lamp house, large enough to accommodate 7-inch top and bottom carbons. The new vertical lamphouse shutter works between lamp and condenser. Saving of condenser breaking 85 per cent Our new lamphouse transport spindle to shift from moving pictures to stereopticon, no more burning of fingertips. A solid (not soldered) brass screw con- denser, oxidized, with two 4%-inch con- densers. Condensers of 8 and 9-inch back focus are used exclusively. Arc lamp focus fully 4%-inch between carbons and piano surface of back con- denser, saves condensers from breaking. A quadruple insulated arc lamp. The lamp mechanism outside of lamp- house, therefore keeps cool and doesn't get out of order. No live carbon arms (on account of the quadruple insulation). Patented ball joint socket for "the stereo- lense enables the operator to project the stereopticon picture in exact unison with the moving picture, no bending of the stereo-arm necessary. A 5-inch diameter water cell held by a special bracket with metal cone and located between condenser and movng picture aper- ture plate, intended when filled with alum Showing Geneva Eccentric and Set Plate. The Geneva cross or starwheel is in one piece with the shaft, cannot get loose and can easily be replaced; both parts are made of stub steel. . The starwheel with shaft is mounted in a single eccentric bearing of fully 2%-inch length. The dead motion between driver and starwheel is adjusted with only one screw and slotted steel set plate, fastened to the long eccentric bearing. Running off of., the film from either of the sprockets is impossible, therefore a great saving of films. . — An absolutely free passage for the up- per and under film loop. Our new film centering device, a quick knob adjustment with friction spring. Showing Magazine, Rewinder, Film Shields, and Double Belt System, Round magazines, large .enough to ac- commodate the film reel without too mud air space. The upper magazine is mounted on 1 rewinder bracket and has a notch crank to lock if in use and to unlock if not in use. The under magazine is stationary, fas- tened to the table web. • The under film reel receives its wind op power by steel belt transmission over an- other set of pulleys from a small puEtj mounted on the under sprocket shaft If the exhibitor desires to rewind ths show film right after the performance he can do so by using the upper rewinder, without taking the reels out of their mag- azine ; upper magazine 'does not need to be taken down and replaced by a naked, left- handed'rewinder as usually done. All parts are interchangeable. All pinions, miter, level, spur, intermit- tent gears and sprockets are cut in oni factory on our own special machinery, un- der expert supervision. Built strictly observing the rules of the fire underwriters. €* A ^ Osygen and Hydrogen W*^ In Cylinders. - - - Lime Pencils, Coadensors, Etc Prompt Service, Seasonable Rates -ALB4NY CALCIUM LIGHT CO. 26 William St., Albany, H.

Film centering device feeds 1% of one film, picture in a straight vertical line. An absolute stationary film shutter (not traveling up and down) only 3 inches in diameter. Film shutter is provided with dissolving edges, three fingers are passing over the aperture while the picture is projected, eliminating to a minimum the contrasty pulsation of light and dark from one pic- ture to another.
