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. 1880 Excerpt: ...for cotton-warps with three compartments, a Friction Calendar with three rolls, and a Drying-Machine with three cylinders, each sixty inches in diameter by thirty-eight inches long, which is designed to run in connection with a calico printing machine. The exhibit as a whole is exceedingly creditable not only to the firm, but to the manufacturing industries of Philadelphia. Mr. L. P. Juvet, Ok Glen's Falls, New York, makes an exhibit of a Time Globe, which has attracted a large amount of attention from its novelty, not only as a curious piece of mechanism, but also as possessing great simplicity of construction and usefulness. The instrument, represented by the accompanying engraving, consists of a terrestrial globe mounted in a vertical circle and provided with adjustment, so that its axis may be placed at the proper inclination and in the proper direction to give it exactly the same position as that of our earth. By means of chronometer mechanism within its interior, the globe is made to revolve once in-twentv-four hours, and a fixed hour-circle, or zonedial, surrounding it at the equator, gives the time of the various meridians or localities on its surface, while the mean time of the place where the instrument is in use is given in the usual way by a dial, with minute-and hour-hand placed, as shown in the engraving, at the north pole. To set the apparatus in operation for any particular locality, the hands of the clock-dial are moved until they accord with the time indicated by the longitude of that place on the zonedial at the equator, care being taken that the globe occupies its proper sidereal position by the compass, and also gives by the zone-dial the actual time of day or night, as the case may be, for this locality. By means of a sliding vernier o...
