This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1895 Excerpt: ...measured round the circumference of the shaft, given by, --Rule 178. (Half circumference of shaft)--(part of circumference intercepted between centre lines of ahead and astern eccentric positions). The arrangement will be readily anderstood on reference to Fig. 51. JOY'S VALVE GEAR. The general arrangement of one form of this gear is shown in Fig. 52. The method of laying down the centre lines is as follows: --Take a point d (Fig. 53, page 172) on or near the axis of the connecting-rod, such that its extreme transverse vibration is about twice the full stroke of the valve (better rather more than less); and through its extreme positions d cZ2 draw zz. Then mark off e and elt--the extreme longitudinal positions of the point d, --and from these points draw two lines to meet in a point/on zz, the position of which is sucb that the angle efe is not more than 90 (if there is room a less angle is better). The point/should be controlled so as to move as nearly as possible on the line zz; this may be effected either by an "anchor" link 2, --which may be placed on either side of zz, --or by a sliding Fig. 52. Xext, on the valve rod centre 5, mark off gl and g$, so that ggt is qual to lap + lead for the top or back end of cylinder, and gg% equal to same for crank end of cylinder. Then take a point j on the link -!/so that e!/ is about 4/3xZ1, and draw jglt cutting zz in m; in will be the fulcrum of the lever 3, and will also be the centre of the curved reversing block in which the fulcrum slides. When swing links are used (as in Fig. 52), in lieu of a curved block, the arcs described by the link ends, when in ahead and astern positions, must intersect in M. The position assumed for; ' in the first instance is approximate only, and may not be quite correct; ...
