478 MOTION PICTURE HANDBOOK
No. 1. — To remove the casing from the Super-Kinetoscope, first open both doors and at the top hinge corner will be found a stop. Release the stops on both doors by taking out the screw which fastens them to the door casing. Next remove screws 26245 (four of them) P. 1, and take off the revolving shutter casting, then remove nine round head screws in the front plate (lens end), which will release the entire front plate and the two doors. You may then take off the back plate by releasing the set screw in knob 26205, P. 1, and removing three round head screws at the top and three at the bottom. In replacing the mechanism on its base, first, before you set it down on the base, pull the automatic stop 26131, P. 3, back so that it stands straight up, also guide vertical shaft so that the screwdriver-shaped end enters takeup friction disc slot. If you don't do this the contact pin which sets down in a slot in the casting is likely to strike and become injured. There are two dowel pins in the base. Set down the mechanism so that it enters the pins.
No. 2. — The mechanism is released from base casting 26290, P. 4, by removing hexagon head screws (three of them) 26019.
No. 3. — Balance wheel 26184, P. 4, may be removed as follows : With a large screwdriver remove screw 26186, P. 4. In the face of the wheel hub will be seen a slot. Set this slot straight up and down and with the point of the screwdriver tap sharply on the top edge of what appears to be an offset in the casting of the wheel but what is really a key washer. A sharp blow will displace this washer, whereupon, holding) gear wheel 26277, P. 4, stationary, pull the balance wheel off the spindle with a twisting motion. The reassembling is but a reversal •of the foregoing process, but be sure to get the key washer properly located in its slot.
No. 4.— To remove gear 26277, P. 4, follow Instruction No. 3 and remove hexagon nut 20622, P. 3, and tap lightly on the end of the bolt, the head of which is shown at 26042, P. 4. Having removed the bolt, the gear may be taken away, carrying with it pinion 26277, P. 2. This pinion may be removed from the large gear and replaced, but the job can only be done at the Edison factory. Don't try to have your local machinist do it unless you are looking for trouble.
No. 5. — To remove gear 26031, P. 4, follow instructions Nos. 3 and 4 and, holding the gear stationary with a large screwdriver, remove screw 26033, P. 4, and, using a hard wood or copper punch, drive the shaft out. In the end of the shaft will be found a key. Be careful and don't lose it; also don't
