(2.) In tubular boilers, in combination with them, tubes carrying fire and surrounded with water, having their smaller ends fixed to the furnace tube-plate and their larger ends fixed to the smokebox tube-plate, said tubes being of a regular taper from end to end, all substantially as set forth.

No. 23837.—18th December, 1907.—JAMES THOMAS HUNTER, of Queen’s Chambers, Wellington, New Zealand, Registered Patent Agent (the nominee of Linotype and Machinery Limited, of 188 and 189 Fleet Street, London, England—the assignees of Christian Augustus Albrecht, of 8 Paulstrasse, Berlin, Germany, Engineer; Frederick Gentzer, of Faunbrake Avenue, Lucknow, India, Superintendent; Carl W. Grasnick, of 26B Grosse Selenna, Quart 25, St. Petersburg, Russia, Compositor; Ferdinand John Wich, of Cumberland Hotel, St. Georges Street, Capetown, South Africa, Engineer; and John Ernest Billington, Engineer, Charles Holwell, Engineer, John Henry Joy, Engineer, and Herbert Pearce, Engineer, of Linotype Machinery Works, Broadheath, Altrincham, Cheshire, England). Improvements in typographic composing and distributing machines.

Extracts from Specification.—This invention relates to improvements in typographic composing and distributing machines employing series of loose matrices, such machines, for instance, as those known as linotype machines, adapted to produce type-metal bars with printing-faces cast on one edge, and which are known as linotypes, and other machines adapted to cast logotypes and separable types. . . 1 is the stationary frame of the machine; 2, the magazine; 3, one of the set of escapements pivoted upon either the frame 1 or upon some piece fixed thereto and independent of both the magazine-supporting frame 4 and the magazine 2; 5, the transverse rod in the frame 1 on which the frame 4 turns when it is raised or lowered; 6, the transverse bar fast on the bottom face of the magazine 2 near its delivery-mouth, and 7 one of the notches in the frame 4 in which the said bar engages to hold the magazine on the said frame; 8, the cam on each side of the magazine 2 and fast on a shaft 9 turning in bearings in the frame 4; 10, a roller on the respective side of the frame 1 for the respective cam 8 to rest and turn on; 11, the hand-lever fast to each cam 8 for turning both of them simultaneously; 12, the hook at the outer end of each lever 11; 13, a transverse bar fast on the bottom face of the magazine 2 near its entrance-mouth, the two ends of the bar projecting laterally beyond the respective sides of the magazines to engage with the respective hook 12; 14, the top portion of the channelled guide-plate down which the matrices pass from the magazine to the assembling mechanism; 15, the distributor; 16, the channelled magazine entrance through which the matrices re-enter the magazine 2 after they have dropped from the distributor; 17, the axis pivoting it to the frame 4; and 18, a spring (one on each side of the machine) holding it in working position. 19, as shown best in dot-and-dash lines in Fig. 1, is a hollow in each of the levers 11, adapted to fit upon the respective roller 10, as shown in full lines in that figure. So long as the frame 4 and the magazine 2 on it are in the composing position the levers 11 are pointing to the rear as shown in full lines in Figs. 1 and 2, the hollows 19 in them resting on the rollers 10. When the operator wants to make a “change,” he pulls both levers 11 to the front into the dot-and-dash position of Fig. 1. As the cams 8 roll on the rollers 10 their eccentricities raise the fronts of both the frame 4 and the magazine 2, thereby completely disengaging the latter from the set of escapements 3. The operator then lifts the front of the magazine till the bar 6 is clear of the notches 7, and pulls it to the front till the ends of the bar 13 come up to the hooks 12, whereupon he lets the magazine swing into a vertical position and then lifts it off the levers 11. The substitute one is then hung on to the levers 11 by the ends of its bar 13, pushed up the frame 4 till its bar 6 engages in the notches 7, and both levers 11 reversed, thereby lowering both frame 4 and substitute magazine into the composing position. All the parts and operations just enumerated are either present in the linotype machines of commerce or described in the specifications of improvements thereof.

[NOTE.—The above extracts from the specification are inserted in place of the claims.]
