Description

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. 1903 edition. Excerpt: ...cradle to retain the rest always at a right angle to the bed. In the face of the lower slide a tee-groove is turned out, and in the centre of the plate a projection is left on which the main slide fits and revolves; two steel bolts with tee-heads are fitted to the groove and pass through two round holes in the base of the top slide, being tightened by hexagonal nuts with washers. This way of fitting up such a slide-rest is vastly superior to the original method, which consists of quadrant slots only, that simply admit of the rest being turned to a limited angle; and if required for surface work the two bolts must be removed and replaced in different holes, or the cut must be taken over the surface with the top slide when moved to the extreme end of the lower slide. With the improved action which the author now adds to this particular slide-rest, by slackening the two nuts it can at once be moved to any desired angle, from its position of parallel to the lathe-bearers, to a right angle, or transversely across the bed to turn a surface; all of which are denoted by a divided scale. The main slide is made longer than usual, which is found to be of considerable service, and is fitted with a screw of ten threads to the inch, carried through at the end in order that the spiral apparatus may be adapted at any time. On the top of the main slide another one is fitted to work at right angles to it, for the purpose of setting in the depth of cut, and this is fitted with Professor Willis's tool-holder, provided with an extra long centre-pin so that vertical slides or other useful adjuncts may be employed. The main screws are both covered, although not shown; this is to prevent the shavings and dirt getting to them, and prevents much wear. The handles are...show more
