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.

Power's Six-B Mechanism
THE Power's No. 6 Mechanism is of the "open" type in that it has no protecting casing. Thus all the gears and machinery are directly under the eye of the operator. In referring to these instructions the numbers refer to parts and plates. Thus: 738, P. 2, means that the part indicated is shown in Plate 2, which in this case is the screw holding the upper and the lower sprockets to the shaft.
No. 1. Removing Main Driving Gear and Spindle. — To remove main driving gear 630, P. 4, and its spindle 631, P. 4 and 7, first remove crank 632, P. 5, and taper pin, 795, P. 2, which engages the slot in the hub of the crank. This is a taper pin and in the later machines a prick punch mark will be found on the end of shaft 631 P. 4. This mark is opposite the large end of the pin. Having removed this pin, the 'shaft and gear may be withdrawn, and, if desired, the gear may be removed from the shaft by taking out the taper pin in its hub.
No. 2. To Remove Shaft 618, P. 4, Carrying Gears 620 and 619, P. 4, first follow Instruction No. 1, then loosen screw 738, P. 2, backing it off some distance, as it is countersunk into the shaft, whereupon the shaft and gear may be withdrawn from the gear side.
