County, Pennsylvania, United States of America; the assignees of John Henry Lubbers, of Allegheny County aforesaid, Glass-worker). Method of and apparatus for drawing glass.

Extract from Specification.—This invention relates to the formation of glass articles, such as sheets or cylinders, by drawing such articles from a body of molten glass within a suitable furnace or chamber; and it is designed to overcome the numerous difficulties which have heretofore prevented the obtaining of commercial glass sheets or articles in this manner. For this purpose shields are arranged over the body of molten glass to protect the bath at the point at which the sheet is drawn from the surrounding heat; further, the invention consists in providing a chamber into which the sheet passes as it is drawn, and which prevents breakage; mechanism arranged to hold the edges of the sheet as formed and prevent its narrowing in width, this mechanism being preferably arranged to also pull or stretch the glass so as to keep it of the proper width; means for supplying heat to the drawing-chamber; a drawing-chamber arranged to cool the intermediate portion of the glass sheet in advance of the edge portions, so as to prevent warping or bowing; devices for cutting off the lower end of the sheet from the bath after it has been drawn the desired length; and a leer which leads from the drawing-chamber, and in which the glass is gradually annealed and cooled so that it may be saved. And, further, the invention consists in certain combinations and features of construction, and in the method of drawing, as more fully described.

[NOTE.—The above extract from the specification is inserted in place of the claims.]

No. 17567.—25th February, 1904.—FREDERICK DWIGHT JOHNSON, of Palace Chambers, 9, Bridge Street, Westminster, Middlesex, England, Engineer. Improvements in and relating to pneumatic percussive tools and the like.

Extract from Specification.—This invention consists in improvements in hand, portable, pneumatic, and like percussive tools, more particularly adapted for rock-drilling, stone-cutting, and like operations, and relates principally to tools of the type in which a distributing-valve (for controlling the admission of fluid pressure to and its exhaust from either end of the hammer-cylinder) works in a valve-chamber or bushing in the bore of the cylinder or in the handle-base. The invention consists principally in providing a reciprocating piston or pistons which during the working of the hammer are actuated by fluid pressure, and thus actuate gearing which rotates the tool-holding sleeve or socket.

[NOTE.—The above extract from the specification is inserted in place of the claims.]

No. 17573.—25th February, 1904.—EDWIN PHILLIPS, of 533, Collins Street, Melbourne, Victoria, Australia, Certified Patent Agent and Engineer (nominee of Otho Cromwell Duryea and Morris Columbus White, both of 933, Georgia Street, Los Angeles, California, United States of America, Mechanics. High-compression gas or vapour engine.

Claims.—(1.) In a free-piston engine, arranging and forming the pistons and cylinders so that the former are capable of entirely filling up the ends of the latter, whereby an extremely high compression of the interposed charge can be obtained on the return movement of the pistons. (2.) In a free-piston engine, an automatic ignition of the charge by means of the high compression of the same, substantially as described. (3.) In a free-piston engine, continuing the compression of the charge after the self-ignition of the same, substantially as and for the purpose set forth. (4.) In a free-piston engine, forming a deflector on the back end of the piston and a recess in the cylinder for this deflector to enter on its return stroke, substantially as and for the purpose described. (5.) A free-piston engine with interconnected self-balanced free pistons, the various parts of which engine are arranged and coact substantially as set forth, and as shown in the drawings.
