Página 3 - Vernier is smaller than each division on the bar by one thousandth part of an inch. If the sliding jaw of the Caliper is pushed up to the other, so that the line marked 0 on the Vernier corresponds with that marked...

Página 419 - The plan is to make a mixture of one part common nitric acid and one-half part sulphuric acid in a stone jar, having also ready a pail of fresh water and a box of sawdust. The articles to be treated are dipped into the acid, then removed into the water, and finally rubbed with sawdust. This immediately changes them to a brilliant color.
Página 3 - To read the distance the caliper may be open, commence by noticing how many inches, tenths and parts of tenths the zero point on the Vernier has been moved from the zero point on the bar. Now, count upon the Vernier the number of divisions, until one is found which coincides with one on the bar, which will be the number of thousandths to be added to the distance read off on the bar. The best way of expressing the value of the divisions on the bar is to call the tenths one hundred thousandths (.100),...
Página 3 - On the sliding jaw is a line of division of twenty-five parts, numbered 0, 5, 10, 15, 20, 25. The twenty-five parts on the Vernier correspond, in extreme length, with twenty-four parts or twenty-four fortieths of the bar, consequently each division on the Vernier is smaller than each division on the bar by one thousandth part of an inch.
Página 30 - The blade which is clamped by an eccentric stud against the edge of the disc, may be slipped back and forth its full length, or turned at any angle around the circle and firmly clamped at any point, adapting it for work in positions where others cannot be used, and rendering the common universal bevel generally used for transferring angles unnecessary. One side of the stock being flat, makes it a convenient tool for laying on paper in drafting, and it has double the utility of any other tool of the...

Uses of the Steam-engine Indicator. — The steamengine indicator is an instrument for drawing a diagram on paper which shall accurately represent the various changes of pressure on one side of the piston of the steam-engine during both the forward and return stroke.
Página 3 - Fig. 102 is a line of inches numbered 0, 1, 2, etc., each inch being divided into ten parts and each tenth into four parts, making forty divisions to the inch. On the sliding jaw is a line of division of twenty-five parts, numbered 0, 5, 10, 15, 20, 25.
Página 30 - The Protractor. A universal bevel protractor is illustrated in Fig. 106. The disc is graduated in degrees from 0 to 90 each way, and rotates the entire circle on a central stud inside the case. The blade which is clamped by an eccentric stud against the edge of the disc, may be slipped back and forth its full length, or turned at any angle around the circle and firmly clamped at any point, adapting it for work in positions where others cannot be used, and rendering the common universal bevel generally...
