November 24, 1916. be both cheap and easy of manufacture, shall not deteriorate if exposed to damp or moisture or to a high temperature, and consists in folding and rolling waste paper to form a bundle, which is then bound with wire or other suitable material, and immersed in melted paraffin wax, so that the wax per- meates the paper. Fig. 1 is a view showing the appearance of a bundle 9 after immersion in the wax; and fig. 2 is an end view, a indicates a sheeit of paper of suitable length and width to produce a bundle of the desired size. The paper is folded and re-folded so as to produce a strip comprising three double thicknesses. This strip is first transversely and then again transversely folded, the point of folding in the second instance being somewhat beyond the centre of the length of the strip, so that the single edges w of the paper, when the paper is rolled to form a bundle, are some distance away from the end of the .strip (fig. 2). b indicates the wire by which the roll of paper is secured prior to and during its immersion in the heated wax. In practice, a sufficient permeation of the 0 » J* 9/ paper is secured if the temperature of the wax be 140 degs. Cent., with a period of immersion of from 10 to 15 minutes. This treatment is sufficient for a bundle of 3J in. length and 1| in. diameter. (Two claims.) 1016 7 9. Improvements i n Apparatus for Cleaning Boilers. H. J. Lund, of Skien, Norway. —Relates to an apparatus for cleaning such parts of boilers as are difficult of access, and is of the type of apparatus in which a pivoted pick is jointed to an operating rod, extending through a tube or barrel, and intended to be moved to and fro, so as to cause the pick to strike against the surface to be cleaned. The improved apparatus is illus7 trated in the accompanying draw- ing in side elevation. At the front end of a tube 1, which is kept in position against the wall 2 of the boiler, and the wall 3 of the fire box by means of springs 4 and 5, the latter of which can be adjusted by means of screws 7, is provided an arm 8, having pivoted on its free end a lever 9, whose other end 10 is shaped into a pick head. On the top side of the said lever 9 is secured at its outer end a link 12, which is connected with a rod 13, extending through the tube 1, and provided on its free end, which extends beyond the end of said tube, with a handle /4 15 may be caused to strike with its edge against the boiler face.

Marston, of 48, Albert-terrace, Middles- brough, Yorkshire.—Relates to rope gearing, in which a rope passesi over a winding drum and a pulley, and is designed to prevent the wear of the rope owing to friction and strains caused by the rope passing from the winding drum to the pulley at an angle to the axes of the pulley and drum. Fig. 1 is a front ele- vation ; fig. 2 a side elevation; and fig. 3 a plan. Each winding drum A is mounted upon a driven shaft B, and each drum has two spiral grooves C to receive the ropes D D1. E E are pulleys, each having a single spiral groove F similar to the groove for the rope D on the winding drum A. The pulleys E E are mounted so that their axes are parallel with the driving shaft B. By means of the spiral grooves on the winding drums and pulleys, the ropes D pass from one to the other at a right angle to their axes, as is shown in fig. 3. The ropes D pass from the drums A and the pulleys E and the ropes D1 from the drums A to the platform H of the hoist, and are attached at points so that the angle which the ropes make with the winding drum or guide pulley is the least possible. (Two claims.) 101755. Improvements in and Relating to Signalling Appliances for Collieries and the like. J. Neil, of J. and J. Neil, of 93, Hope-street, Glasgow.—Has reference to and comprises improvements in signalling appliances for collieries and the like, which are designed for transmitting signals from the pithead, pit bottom, or other locality to the engine house, and visibly recording the number and nature of such signals conveyed at each time of signalling, and consists of a new or improved construction, arrangement, and combination of “ cancelling gear ” mechanism, which is provided for automatically cancelling the signals made and indicated when the engine starts to wind. Fig. 1 is a sectional elevation of the cancelling gear; figs. 3 and 4 are diagram- matic elevations at right angles to each other; fig. 5 is a sectional elevation; and figs. 6 and 7 are diagrammatic elevations at right angles to each other. An arm 1 is con- nected to the sleeve 2 of the governor ball mechanism 3, driven from the winding engine, so that as the sleeve 2 moves along the spindle 4 under the influence of the balls 3, the arm 1 moves with it. The. arm 1 is secured on a collar 5 loosely mounted on the sleeve 2, and having a downwardly projecting arm 6 adapted to slide on a guide rod 7, so that the arm 1 will always remain in the vertical position. A lever 8, which may be counter-weighted, is connected by ita two ends to one of the moving parts of the indicator mechanism, which indicates on the indicator dial the signal made, and is mounted on its centre part to oscillate on a pin 9. The connection between the ends of the lever 8 and the indicator mechanism consists of chains or the like 10 attached by their one ends to the lever 8 and by their other ends to the one end of a slidable rod 11, which is connected by its other end to the indicator mechanism by flexible con- nections. When the lever 8 oscillates in either direction the rod 11 is pulled. An arm 13 formed at the centre part of thisi lever 8 is so arranged that the moving arm 1 of the governor sleeve 2, on striking same, rocks the lever 8 on its pivot, and thus pulls the connection to the indicator mechanism, so as to cancel the signal made. When the governor speeds up, the arm 1 is kept clear of the lever 8, and signals made while winding are cancelled by the governor slowing towards the end of wind. Rollers 12 are arranged on the arms 1 and 13, so as to minimise vibration or shock when arm 1 strikes arm 13. The pull on the con- nection between the cancelling gear and the indicator mechanism may be obtained, as in figs. 3 and 4, by attach- ing the connection by means of a pin 14 to a friction disc 15, loosely mounted on the governor spindle 4, and adapted to be rotated by a disc 16 secured to the governor sleeve 2. After the engine starts to wind, the disc 16 on the sleeve 2 leaves the loose disc 15 under the influence of the governor balls 3, so that the loose disc 15 only rotates a part of a revolution. As illustrated by fig. 5, the spindle 4 of the governor may be arranged vertically with the loose disc 15 over the disc 16 on the sleeve 2, so that the loose disc 15 will follow the disc 16 on the sleeve along the spindle 4 for a certain distance, so as to ensure that the loose disc 15 will rotate a sufficient distance to cancel the signals. A modification illustrated by figs. 6 and 7 consists in forming the disc 16 of the governor s'eeve 2 with a projection or projection 17 adapted to engage the end of a lever or levers 18 (as the disc 16 is rotated) the other ends of which are attached to the connection to the indicator mechanism.
