We use Optical Character Recognition (OCR) during our scanning and processing workflow to make the content of each page searchable. You can view the automatically generated text below as well as copy and paste individual pieces of text to quote in your own work.
Text recognition is never 100% accurate. Many parts of the scanned page may not be reflected in the OCR text output, including: images, page layout, certain fonts or handwriting.

moving two screws, one at either front top corner of mechanism casing, and two screws from the inside of lower corners of the front plate (front plate is plate which is next screen), which screw into the base; also a large screw in the middle front of top plate. This latter screw engages the large round rod on the frame slides. Next remove lens barrel bracket by taking out three screws CS-31, P. 6, and two screws, not shown, which secure other end of bracket to round slide rod CS-13, P. 6.
INSTRUCTION NO. 39.— TO REMOVE THE FRAMING PARTS, which are located on under side of base of mechanism, remove gear segment FR-10, P. 7, by driving out the taper pin which secures gear segment to stud FR-11, P. 7. Having done this you may then remove double gear FR-7, FR-8, P. 7, by taking out screw FR-9, in center of stud on which gear rides. Pinion FR-2, P. 7, is removed by driving out taper pin which secures it to framing screw FR-I, P. 7. Framing handle FR-13, P. 7, is removed by screwing it out, using a plier if necessary, lining its jaws with paper to prevent scarring handle.
INSTRUCTION NO. 40.— BALANCING AND TENSION OF MECHANISM FRAME. The mechanism frame is balanced by spring SF-41, P. 6. The tension of this spring is adjusted by a slotted screw nut located back of top magazine and about two inches from front of mechanism frame. The tension of the sliding frame is regulated by two screws, SF103, P. 6 and 7, which clamp the sliding frame to the round slide rod, CS-13, P. 7. The rear of the sliding frame is guided by the square slide rod, CS-14, P. 3, and 6 and the guides are adjusted to the square rods by two screws, SF-106, P. 6, one near top and one near bottom. These screws should be only tight enough to prevent any vibration or shake of sliding frame and the tension (ease of sliding) should be regulated by screws SF-103, P. 6, which latter should be set just tight enough to prevent the sliding frame from "crawling" when the projector is in operation. If too loose the frame will crawl. If too tight the framing handle will work too hard.
INSTRUCTION NO. 41— THE SPEED CONTROL. The
driving disc is mounted directly on the motor shaft, and is held in place by a set screw. The speed of projector mechanism is altered by rocking the motor on the shaft of the motor support, SC-20, P. 9. Attached to shaft of motor support, SC-20, P. 9, is an arm, SC-22, which is held in place by
