Abstract: 9781. Jacques, G. May 5. Rock drills.-Relates to means for removing dust when drilling bore-holes. In the form shown in Figs. 1 and 2, a pipe 1 has at its rear end a rubber washer 2 to provide a tight joint with the drill. An inner pipe 12 with a conical end 13 has studs 16 to engage grooves 15 in segments 14. These segments have conical portions to fit the conical end of the pipe 12, and are held in position on the pipe by a split ring 17. The conical end 13 and segments 14 are placed in the mouth of the bore-hole. The pipe 12 is then rotated and displaced to the right by means of a pin 18 passing through a helical slot 21. The segments 14 are thus forced outwards, as shown in Fig. 2, to grip the sides of the hole. The segments may be surrounded by a rubber ring to ensure a better grip. A branch 6 on the pipe 1 leads to a dust-receptacle, and a box 8, perforated at the top 11 and bottom 9, is packed with wadding which acts as a filter for the escaping air. In a modification, shown in Fig. 4, the inner pipe 12 is replaced by a sheet-iron pipe 22. The diameter of the pipe is reduced by means of a screw clamp 29. The pipe is placed in the bore-hole and the clamp is unscrewed. A felt washer 31 is provided to form a joint round the mouth of the bore-hole.

Abstract: 16,180. Clutsam, F. July 30. [Patent of Addition to No. 12,323, A.D. 1907.] Pianofortes; organs &c.-In a curved keyboard for a pianoforte or organ, preferably of the kind described in Specification No. 12,323, A.D. 1907, the keys near the ends are made broader than the keys near the centre in order that the hand in its natural position may be able to play the same interval on any portion of the keyboard. The white keys are set off so as to increase gradually in breadth from the centre of the keyboard, and the lines separating adjacent white keys are perpendicular to the contour line a<1>, a, the lines separating the various pairs of notes B, C, and E, F, such as a', b<2>, c<2>, a<3>, b<3>, c<3>, &c. being extended to the contour line c<1>, c. The note mid-way between the lines a<4>, c<4> and a<3>, c<3> is bisected by a line a<6>, b<6>, which is extended to c<6>, and the lines c<4>, c<6>, b<4>, b<6>, c<6>, c<3>, and b<6>, b<3> are each divided into five equal parts, c<7> to c<14> and b<7> to b<14> respectively. Lines joining the points b<10>, c<10> and b<8>, c<8> determine the boundaries of the note D sharp, and lines joining the points b<11>, c<11>, and b<13>, c<13>, determine the boundaries of the note C sharp. The other notes are similarly determined by dividing the lines c<3> c<15>, b<3> b<15>, c<15> c' and b<15> b' respectively into seven equal parts. Or the boundaries of the black keys may be determined by dividing the lines c<3> c<3> and b<3> b<2> into seven equal parts and the lines c<4> c<3> and b<4>, b<3> into five equal parts. In a modification, the white keys in the octaves near the ends of the keyboard are wider than the keys in the octaves near the centre of the keyboard, suitable dimensions being given in the Specification, and the edges of the four centre notes may be parallel to the centre line. A method of setting out curved keyboards so that the distance between C sharp and D sharp, and F sharp and G sharp, shall be equal for any octave is also described.

Granted: 1909-03-11
Abstract: 20,976. Fairweather, W., [Aktiebolaget L. M. Ericsson & Co.]. Oct. 5. Electric clocks.-To avoid the sparking due to interruption of a current, the electro-magnetic actions are obtained by charging and discharging a condenser instead of by passing a continuous current. Fig. 1 shows diagrammatically the arrangement. The battery 1 charges the condenser 2 when the switch 5 in the main circuit is closed, and the condenser is discharged when the switch 6 in the bridge is closed, one switch being opened when the other is closed. Fig. 2 shows the application of the invention for actuating a pendulum. The cross-bar 15, pivoted with insulation at 16 on the pendulum rod 9 under a weak controlling-spring 17, makes and breaks contact at terminals 18 and 19 of constant potential. The condenser 20 is charged through the left half 13 of the cross-arm 15, the spring 17, an insulated wire in the rod, the electro-magnet 11 under the bob, the rod itself, and the fixed electro-magnet 12 below. It is discharged by the reverse route and the right half 14 of the cross-arm. The arm 15 might operate a ratchet-wheel.

Title: Improvements in and relating to Apparatus for Lighting and Extinguishing Gas.
Filed: 1908-10-16
Granted: 1909-11-16
Abstract: 21,887. Down, H. L., and Telephos, Ltd. Oct. 16. Lighting and extinguishing gas.-In electricallyoperated apparatus for controlling gas valves from a distance, of the type described in Specifications Nos. 29,345 and 29,346, A.D. 1904, a platinum-wire igniter is used in conjunction with an auxiliary burner of the Bunsen type. Fig. 3 shows the construction of the auxiliary burner. The heating- coil j, guard k, and Bunsen tube m are supported by an insulating-block i which is secured to the lower ends of the gas tubes f, which also serve to convey current to the coilj. The tubes are bent at right-angles and formed with holes p on their underside, from which the gas passes to the burner. The upper ends of the tubes f enter holes in nipples 24 screwed into a block carried by the casing of the auxiliary valve g, Fig. 7. Modified construotions of the burner are described in which the current is conveyed to the coil j by independent leads, or by one wire and one gas tube, or by concentric conductors, one of which may be a gas tube. In the valve-actuating mechanism shown in Figs. 7 and 8, the main valve d of the perforated-disk type'and the auxiliary lift valve g are both controlled by a magnet e. The first excitation of this magnet opens the valve d by a pawl 15 and a ratchet, and also lifts the valve g through the medium of a pusher-bar t and a bell-crank lever 4, 5. When the circuit is opened, the valve d remains open but the valve g closes. The-gas is extinguished by again exciting the magnet e, thereby moving the valve d to shut off the gas. Modified forms of valveactuating mechanism are described in which the auxiliary valve g is operated by the stray magnetic field, or by the flux in a gap in the magnetic circuit of the magnet e. The auxiliary valve may also assume other forms, such as a slide valve carried by the armature s, or it may be located in a separate casing with independent electro-magnetic actuating-mechanism. To prevent undue heating of the mechanism, the chamber a is arranged within a shell of thermally non-conducting material 17, and the mechanism is insulated from the burner proper by means of a metal bush 18, an insulating-bush 20, and a metal socket 21. Specifications Nos. 24,307, 24,308, and 24,309, A.D. 1909, are referred

IPC: F16H3/26
Filed: 1909-02-06
Granted: 1910-02-07
Abstract: 2891. Roberts, H. D., and Salmond, H. Feb. 6. Driving machines.-A variable - speed gear in which the speed variation is effected by a toothed gear sliding on a countershaft is combined with change-speed gearing comprising loose sleeves on a main shaft. The invention is specially adapted for driving machine tools and is regarded as an improvement on the invention described in Specification 1796/08, [Class 80, Mechanism &c.]. On the main shaft a, Fig. 1, is a loose sleeve b, which is driven from a belt pulley e and carries toothed gears c, d. A second sleeve f is driven from a belt pulley h and carries a pinion g. The gears c, g mesh constantly with a double gear t, q loose upon the countershaft n and connected thereto by a ratchet clutch s. A gear m similar to the gear d is secured to the shaft a. A pinion z secured to the shaft n is constantly in mesh with a wheel j connected to the shaft a by a ratchet clutch k. A double pinion u sliding on a feather v on the shaft n effects the speed changes. If the belt is on the pulley e, Fig. 1, the drive passes from the sleeve b to the gear t, through the shaft n, and from the pinion z and wheel j to the shaft a. If the pinion u is moved one step to the left, the drive passes through it to the gear m and shaft a, the clutch k overrunning. Further movement causes the gears d, m to be locked together by the teeth of the pinion u. The clutches k, s both overrun. Another movement of the pinion u disengages it from the gear m, and the drive passes from the gear d to the gear u, and from the pinion z to the wheel j and clutch k. A further range of four speeds is obtained by shifting the belt to the pulley h. The pulley 7 is loose. In the modified arrangement shown in Fig. 2, the driving - belt is not shifted, and the second range of speeds is effected by moving a double clutch 13 sliding on the sleeve b. In other modifications, further change-speed arrangements are provided on the right of the pinion u to connect the shafts n, a.
