Excerpt from Dictionary of Arts, Manufactures, and Mines, Vol. 2 of 2: Containing a Clear Exposition of Their Principles and Practice According to Franke, the constituents of stick-lac are, resin, 65-7; substance of the lac, 28-3 coloring matter, 0-6. Sced-lac. - When the resinous concretion is taken off the twigs, coarsely pounded, and triturated with water in a mortar, the greater part of the coloring matter is dissolved, and the granular portion which remains, being dried in the sun, constitutes seed-lac. It con tains of course less coloring matter than the stick-lac, and is much less soluble. John found in 100 parts of it, resin, 66-7; wax, 1-7; matter of the lac, 16-7; bitter balsamic matter, 2-5; coloring matter, 3-9; dun yellow extract, 0-4; envelopes of insects, 2-1; laceie acid, 0-0; salts of potash and lime, 1-0; earths, 6-6; loss, 4-2.

Book Description
This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1867 edition. Excerpt: ...the surface. Revolving suns are wheels upon whose circumference rockets of different styles are fixed, and which communicate by conduits, so that one is lighted up in succession after another. The composition of their common fire is, for sizes below of an inch: gunpowder meal, 16: charcoal, not too fine, 3. For larger sizes: gunpowder, 20; charcoal, not too fine, 4. For fiery radiations: gunpowder, 16; yellow micaceous sand, 2 or 3. For mixed radiations: gunpowder, 16: pitcoal, 1; yellow sand, 1 or 2. The waving or double Catherine wheels, are two suns turning upon the same axis in opposite directions. The fusees are fixed obliquely and not tangentially to their peripheries. The wheel spokes are charged with a great number of fusees; two of the four wings revolve in one direction, and the other two in the opposite; but always in a vertical plane. The girandoles, caprices, spirals, and some others have on the contrary a horizontal rotation. The fire-worker may diversify their effects greatly by the arrangement and colour of the jets of flame. Let us take for an example the globe of light. Imagine a large sphere turning freely upon its axis, along with a hollow hemisphere, which revolves also upon a vertical axis passing through its under pole. If the two pieces be covered with coloured lances or cordage, a fixed luminous globe will be formed, but if horizontal fusees be added upon the hemisphere, and vertical fusees upon the sphere, the first will have a relative horizontal movement, the second a vertical movement, which, being combined with the first, will cause it to describe a species of curve, whose effect will be an agreeable contrast with the regular movement of the hemisphere. Upon the surface of a revolving sun, smaller suns might...

Book Description
Excerpt from A Dictionary of Arts, Manufactures, and Mines, Vol. 2 of 2: Containing a Clear Exposition of Their Principles and Practices Knife-cleaning. - Specimens of those very useful machines which have lately been introduced for cleaning knives and forks are to be found in the building, and demand some notice. Mr. Kent's machine consists of a box or case, containing a couple of wooden discs, fixed near to each other upon a horizontal iron rod or spindle, which passes through the case, and is caused to rotate by means of a winch-handle. Each disc is, for about three-fourths of the area of its inner face, covered with alternate rows of bristles and strips of leather; and the remaining fourth part is covered with bristles only. The knife-blades to be cleaned are introduced through openings in the case, between the rubbing surfaces of the discs; and rotatory motion being given to the discs by a winch-handle, the knives are rapidly cleaned and polished. The machines exhibited by Mr. Masters are constructed upon the same plan as the above; but the rubbing surface of each disc is formed of strips of buff leather, with only a narrow circle of bristles around the edge of each surface, to clean the shoulders of the knives; small brushes are fixed beneath the holes in the case, through which the blades of the knives are inserted, to prevent the exit of dust from the apparatus. Mr. Price exhibited a machine for cleaning knives, and another for cleaning forks. The knife-cleaner consists of a horizontal drum, covered with pieces of leather or felt, and fixed within another drum or circular framing, lined with leather or felt. The knives are introduced through openings, in a movable circular plate, at the front of the outer casing, and enter between the surfaces of the two drums. The plate is fixed upon a horizontal axis, which extends through the case, and is furnished at the back With a handle; by turning which the disc is caused to rotate and carry round the long rectangular opening in the side, behind which two brushes are fixed face to face. Between these brushes the prongs of the forks are introduced, and the handles are secured in a carrier, which is made to advance and recede alternately by means of a throw-crank, and thereby thrust the prongs, into and draw them out of contact with the brushes. The carrier consists of two metal-plates, the lower one carrying a cushion of vulcanized India-rubber for the fork handles to rest upon, and the upper being lined with leather; they are hinged together at one end, and are connected at the other, when the handles have'been placed between them, by a thumb-screw.
