Inventions, Processes, and Wrinkles

Inventions, Processes, and Wrinkles.

Caslon's Galley Quoin and Hold-fast Clump.—Caslon and Co., London, have introduced to the trade two valuable inventions, which can he used either separately or in conjunction. The first is the patent galley quoin, a metal fixture let into the side of the galley, of which it forms a part, and into which it can be completely shut when not in use. Ordinary furniture or reglet is used, the side-stick being superseded, and much less space is therefore needed for locking. In the diagram, A represents the wooden galley side; B, the fixed part of the metal quoins; C, the metal sliding quoin, and D, the bottom of the galley. An advantage of the galley is, that screw-heads in the interior are dispensed with, the metal lining presenting an uninterrupted smooth surface from end to end. Those who have had matter caught in sliding and upset by a projecting screw-head, will appreciate this feature. The second diagram shows a galley locked up.—The other invention is the « hold-fast » galley clump, supplied with a steel pin fitting into holes drilled at intervals in the furniture or side-stick, as the case may be. With this safeguard, the type cannot fall out, though the galley be tilted downward. The furniture is 6 ems wide, and is made to any length required. We have made trial of both these inventions, and find them to be all they are claimed to be. Galleys with the fittings are supplied at the same rate as those of the old pattern. We find the convenience and saving of time so great in the use of these galleys, that we intend to buy no more of the old-fashioned style.

Fire-proof Paper, for printing and writing purposes, is now manufactured in Berlin by a new patented process. Ninety-five parts of asbestos fibre of the best quality are washed in a solution of permanganate of calcium and then treated with sulphuric acid as a bleaching agent. Five parts of wood-pulp, as used in paper factories, are added, and the whole is placed in the agitating-box with an addition of lime-water and borax. After being thoroughly mixed the material is pumped into the regulating box, and allowed to flow out of a gate on an endless wire cloth, where it enters the usual paper-making machinery. It is easy to apply water marks to this paper, which ordinarily has a smooth surface, but which can be satin-finished, this being preferable for writing purposes. Paper thus produced is said to resist even the direct influence of flame, and remains uninjured even in a white heat.
