Title: Improvements in Steam Boiler and like Furnaces.
Inventor: WHITTAKER WILLIAM
Filed: 1904-03-14
Granted: 1905-01-19
Abstract: 6156. Whittaker, W. March 14. Firebars and grates.-The firebars of steamgenerator furnaces are carried in open-bottomed girders, through which air passes freely to the fire. The arrangement is applicable to furnaces with forced draught, and is adapted for use with the mechanical stoker described in Specification No. 22,921, A.D. 1897. The bars B, B', which are wedge-shaped, as shown in Fig. 4, have vertical ribs J, and are interlocked with one another and with the cross-bars F of the girders A by means of tongues and slots formed at their ends. The outside bars H only touch the girders at intervals, so as to transmit little heat to them. To prevent the ends of the girders from burning, end-blocks K are used, which may be chilled, and which have lips L for retaining the firebars. They are slotted at L' to receive projections cast on the girders. If the arrangement is employed for moving-grates, the heads of the girders may be formed as shown in Fig. 1, so as to be reciprocated by cams P on a stoker shaft. Some of them may be made as shown in Fig. 2, so that they are moved outwards by cams, and inwards by lugs Q, which bear on projections R and are attached to girders of the form shown in Fig. 1. They are supported on ball or roller bearings T', and the cams are so arranged that the motions of neighbouring girders are slightly different. Side-bars with teeth are used for the flue, the teeth being chipped off to suit the curvature.

Title: Improvements in or relating to the Manufacture of Covered Boxes.
Inventor: YOUNG SAMUEL EDWIN
Filed: 1904-05-02
Granted: 1905-03-02
Abstract: 10,049. Young, S. E, Baker, T. H., and Plewman, A. R. May 2. Making paper and like boxes.-In a machine for covering cardboard and other boxes with paper, cloth, or the like, the covering - material proceeds from a reel over a pasting-roller, a scraper, and guide-rollers, to a rotating former on which the box is placed. Means are provided for cutting the paper and for automatically stopping the former after each revolution. The paper passes over the roller 7, Figs. 1 and 2, which dips into a tank containing adhesive, and then between the bars 10, 12 of the scraper, the force with which the bar 12 presses against the strip being regulated by turning the knob 13, and then locking the scraper by the screw 14. Above the guiderollers 15 are rods 17 from which depend adjustable fingers 16. The cutting-apparatus, through which the paper passes, comprises a fixed blade 18 and a movable blade 19, mounted on trunnions or pivots 20. One of the trunnions carries a short crank 21 connected to an arm 23 secured to a spindle 24, at the other end of which is an arm 26. As the boxformer 29 approaches the end of a revolution, the pin 27 raises the arm 26, thus causing the movable blade to descend and sever the paper strip. The box-former derives its motion from the main shaft 35, by gearing as shown. To start the machine, the foot-pedal 42 is depressed, causing the arm 40 to move the shaft 39, on the end of which is the belt fork 38, so as to shift the belt from the loose pulley 37 to the fast pulley 36. The shaft is then locked in this position by the arm 44 of a lever dropping into a notch in the shaft 39, the action being assisted by a spring 46. When the box-former has completed a revolution, the peg 27 lifts the arm 50 of a lever, which, by means of the connecting-rod 47, causes the end 44 to be lifted, and the spring 43 draws back the shaft 39, causing the belt to be shifted on to the loose pulley and throwing the machine out of action.
