No. 12386.—13th February, 1900.—HENRY JOHN ALLEY, of Huirangi, Taranaki, New Zealand, Settler. An improvement in seed-sowing machines—an appliance for converting a Massey-Harris broadcast seed-sower and cultivator into a drilling-machine.

Extract from Specification.—This invention consists essentially of a coulter or hopper A, shown in Figs. 1, 2, 3, and 4, made of iron, either galvanised or black, strengthened in the angles by square or angle iron B as shown in plan, Fig. 4, shaped as shown in Figs. 1, 2, and 3. The bottom or mouth of the said hopper is left open as shown at C, Figs. 1 and 4, and is fitted at the back with an angular iron tooth D, Figs. 1, 2, and 3, to open the ground for the reception of the seed and fertiliser. This coulter or hopper is attached to the spring frame of the Massey-Harris broadcast seed-sower by means of the bars E and the lugs F. These lugs F are recessed as shown to engage the bars of the spring frame of the seed-sower, and are bored and provided with bolts G, so that the coulter or hopper may be securely fastened to the said spring frame.

Claim.—In a broadcast seed-sowing machine, a coulter or hopper shaped as shown and described, fitted with a tooth at the bottom for opening the ground, to be attached to a Massey-Harris broadcast seed-sowing machine, converting the same into a drilling-machine, substantially as described.

Claims.—(1.) The combination with a casing and a reciprocating-device, of a yoke located in the casing and connected with the reciprocating-device, and a crank-shaft whose crank engages a slot formed in the yoke for operating the reciprocating-device. (2.) The combination with a casing and a reciprocating-device of a yoke located in the casing, a yielding connection between the yoke and the reciprocating-device, and a crank-shaft whose crank engages a slot formed in the yoke for operating the latter in conjunction with the reciprocating-device. (3.) The combination with a casing, and a reciprocating-device enclosed thereby, of a yoke also enclosed by the casing, a yielding connection between the yoke and the said device permitting either of them a limited independent movement in either direction, but causing them to reciprocate together, and suitable operating means connected with the yoke. (4.) The combination with a casing, and a reciprocating-device enclosed thereby, of a yoke, also enclosed by the casing and connected with the reciprocating-device, and a buffer-spring located between the yoke and a stop on the reciprocating-device, and suitable means connected with the yoke for operating said device. (5.) The combination with a casing, and a reciprocating-device enclosed thereby, of a yoke, also enclosed by the casing, and connected to move with the said device, and two buffer-springs surrounding the reciprocating-device and engaging stops thereon, their opposite extremities engaging on opposite sides a part of the yoke through which the said device passes, and suitable means connected with the yoke for operating the reciprocating-device. (6.) In a rock-drilling machine or other kindred instrument, the combination with a casing, a guide-shell on which the casing is mounted, and a reciprocating-shaft enclosed by the casing, of a yoke, also enclosed by the casing and yieldingly connected with the shaft, means connected with the yoke for operating the shaft, feed-mechanism mounted on the guide-shell and connected with the casing, and means for automatically rotating the shaft. (7.) The combination with a casing, a guide-shell upon which the casing is mounted, a feed-screw for moving the casing on the shell, a reciprocating-shaft enclosed by the casing, and means for rotating the shaft, of a slotted yoke also enclosed by the casing, and yieldingly connected with the drill-shaft, a crank-shaft whose crank engages the slot in the yoke, a flexible shaft connected with the crank-shaft, and a motor, engine, or other power for operating the flexible shaft. (8.) In a rock-drilling machine, the combination with the casing, a drill-shaft enclosed thereby, and means for reciprocating the same, of means for rotating the drill-shaft, comprising two ratchet-wheels surrounding the shaft, and respectively provided with lugs respectively engaging a straight and a spiral groove formed in the drill-shaft, two detachable keepers located in the casing and respectively enclosing the ratchet-wheels, means for locking the keepers against rotation and longitudinal movement in the casing, and spring-held dogs pivotally mounted on the keepers and engaging the ratchet-teeth of the wheels. (9.) In a rock-drilling machine, the combination with a casing, and a reciprocating-shaft enclosed thereby, of a yoke also enclosed by the casing, and yieldingly connected with the shaft in such a manner as to allow the shaft to rotate, the yoke being locked against rotation, the crank-shaft engaging a slot formed in the yoke, a flexible shaft connected with the crank-shaft, and means for rotating the flexible shaft. (10.) In a rock-drilling machine, the combination of a casing, a reciprocating shaft, an operating crank-shaft, a flexible shaft connected with the crank-shaft, a motor, and a connection between the flexible shaft and the motor comprising two pulleys and a belt. (11.) The combination with a drill-bit or tool, of a reciprocating shaft having a bit-socket in its forward extremity and a transverse opening intersecting said socket, and a fastening-bolt inserted in the said transverse opening and apertured to receive the shank of the bit, the parts being so arranged that the shaft is revolubly balanced. (12.) In a rock-drilling machine, the combination with a guide-shell, and suitable drilling-mechanism mounted thereon, of a supporting-bar, a clamp embracing the bar, a slotted plate bolted to the clamp, and a bolt passing through an opening in the guide-shell and slot of the plate whereby the shell and drill-mechanism may be shifted laterally without loosening the clamp-members. (13.) In a rock-drilling machine, the combination of the casing, the reciprocating drill-shaft, a crank-shaft for operating the drill-shaft, and a fly-wheel geared to the crank-shaft in such a manner that the speed of the wheel is greater than that of the crank-shaft.

No. 12388.—16th February, 1900.—JOSEPH ROSS, Engineer, and WILLIAM DOUGLAS CAIRNEY, Chartered Accountant, both of 45, Renfield Street, Glasgow, Scotland. Improvements in explosives.

Claims.—(1.) Explosives, either in the form of moulds or cartridges, or in a granulated form, and consisting of a mixture of about 87 per cent. of chlorate of potash, 3 per cent. of charcoal, 7 per cent. of paraffin or other suitable wax, and 3 per cent. of vaseline, and all treated in the manner substantially as described.
