Abstract: 16,316. Pifer, G. N. July 22. Automatic apparatus. - In an automatic coin-controlled photographic apparatus, plates, preferably of the kind described in Specification No. 16,318, A.D. 1:102, are stored in a magazine provided with a light-proof cupshaped cap, Fig. 14, and a lower light-proof plug consisting of a rubber disc d<x> with an inwardlyprojecting wood or hard-rubber part d<1>. The magazine is telescoped into a tubular casing carried by the main frame G and the cap is pushed down upon a spherical separator M<1> so as to push the bottom plug through a square opening g, Fig. 8, in a slide-way g<1>. The plates drop in turn into an aperture in a slide N operated by a lever 0 on a spindle 0<1> so as to deliver each plate to an aperture g<3>, semicircular at the near side and straight at the other side, and covered by a light-proof cap G<4> of the form shown. The plate slides down a shoot G<3> and is supported by a valve p<2> on a spindle p<2> with its film towards the camera lens C' which has a shutter c operated by a lever J. The main operating shaft E<1>, Fig. 7, is rotated by a spring motor E mounted on a shaft e carrying two pinions, one of which gears with a segment e<3> on a shaft e' carrying an operating-lever E<2>, while the other operates a train of wheels, one, e<5>, of which is mounted on the main shaft E'. The operating spring is wound by pulling down the lever E<2> until the stop e<6> strikes the side of the casing. When this occurs the segment e<3> is released from the operating-lever by the action of a fixed pin g<6>, Fig. 12, on a detent e<12> pivoted to the segment and having a tooth e<15> engaged by a tooth on a spring e<14>. When released, the handle is returned bv a spring e<16> and when the segment e<3> is returned by the spring motor a second fixed pin g<7> returns the detent e<12> to its locking position. The main shaft carries a disc E<3> having a peripheral notch normally engaged by a stop arm or detent h having an extension h<6> in the path of the fly of the governor D'. This detent is carried by a sleeve h<1> loosely mounted on a rod h<2> carrying the shutteroperating arm J which has a shoulder j engaged by a hinged locking-armature k freed by a magnet K and returned by a spring h<5>. The sleeve h<1> has a recess h<4> engaged by an operating pin on the rod h' which has a projecting lip h<3> operated by a lip e<9>on an adjustable arm E<4> secured by a thumb-nut e<8> to the main shaft E', a pointer e<10> indicating on the graduated disc E<3> the time interval between the opening and closing of the shutter. The shaft 0<1>, carrying the slide-operating arm 0, is connected by a crank o and a connecting-rod o' to the segment e<3>. After the exposure the valve P<3> is turned, so as to allow the plate to fall into a shoot G<9>, by the action on a lip p<3>, carried by the valve-spindle, of a second lip e" on the arm E'. The shoot G<9> leads the plate into a carrier S<3> situated in the developing tank. There are three other tanks containing the washing and fixing liquids, and each has a perforated plate-carrier S<3> attached at one side to a spindle s mounted in frames G<7>, G<9> and operated, so as to tilt the plate into the next tank or the discharge shoot, by a crank s<1>, a rod s<3>, and a trip lever s<12>. These trip levers are operated by two lu gs u<2>, u<3> on the disc E<3> and two lugs on an adjustable arm U clamped in position by the nut and having a pointer u<4> to indicate on the disc E<3> the time allowed for developing. The discharge shoot extends downwardly outside the casing, and has a discharge opening below which is arranged a receiving-cup having an opening at the bottom from which a pipe leadsto a receptacle inside the casing. The electric circuit of a lighting- apparatus, preferably an are light, is controlled by an electromagnetic switch having in the magnet circuit two contacts arranged near the hook carrying a switch handle situated outside the casing. This handle normally holds the spring contact clear of the rigid one, but when the handle is removed the switch closes automatically. During exposure, a pair of contacts in circuit with an electric alarm bell are closed by the arm J. Into the coin shoot B, having a flared upper end and curved to one side at its lower end to clear the lens aperture, projects a wing o<2> on the slide-operating lever to intercept a coin until the slide has been operated. At the bottom of the shoot the coin closes two contacts b<1>, p arranged in circuit with the magnet K. The adjustable screw contact p is secured to a pivoted arm P connected by a rod to an arm on the rock-shaft p<2> carrying the valve P<2>, so that, when this shaft is operated, the contact p is moved to one side out of engagement with the spring contact b<1> and the coin is allowed to drop. Two other contacts k<1>, k<2> in the circuit are closed by the segment e<3>, while a third pair of contacts in the same circuit are located in a handle outside the casing, and are closed by a push-button. When the magazine M is empty, the weight M<1> falls on to the cup-shaped end of a lever G<5> and acts through a rod g<5> to tip one end of a lever G<6> into the shoot B and prevent the insertion of coins.
