the two flat-metal springs beneath the lever on said bell and around the field-magnet coils on said bell, which coils cause the said armature to be attracted by the field magnets, by means of which the point of said lever is disengaged from the pin on aforementioned armature and flies down on to metal screw No. 2 (as described and illustrated), and by so doing prepares the ringing circuit again, and the same time that this happens the two flat-metal springs beneath the lever quit contact with one another, thereby breaking the current in that circuit, and the armature on bell comes back to its normal position. (6.) In the manner in which the three flat-metal springs on the face of said vulcaniser-gauge are held in position on the block of insulating material (as illustrated), which manner consists of the said springs being sunk a small distance on one of each of their edges into slots cut into the said block for the purpose, and the top end of that edge of each of the springs, which is uppermost, being wider than the rest of the said springs, is pierced by a hole and bent over so as to lie flat against the face of the said block, and is then held firmly in position by bolt and nut as described and illustrated. (7.) In the arrangement in combination of all the aforementioned parts, operating substantially for the purposes as described and illustrated.

No. 23120.—11th July, 1907.—DAVID AMEY, of Maffra, Victoria, Australia, Farmer. Improvements in agricultural implements.*

Extract from Specification.—My invention relates to agricultural implements, its objects being to provide sundry improvements to be used either in combination or separately. The full combination comprises an adjustable series of discs for ploughing or cultivating, seed-sowing devices, and a series of rollers, the whole being mounted upon framing suited to them. The seed-sowing attachments may be removed, the front wheels adjusted to inner positions, and the discs regulated in number, depth of cut, and angle to line of draught, and ploughing may then proceed. I may plough with, for example, four discs. When ploughing has been completed I usually increase the number of discs on the disc-axle, and use, for example, eight. The depth to which the discs are to cut is regulated, usually, after the ploughing aforesaid, by being reduced, and the set or angle of the discs to the line of draught is varied as desired; the front carrying-wheels of the implement may be suitably set wide apart, and the seed-sower may be attached. The implement is then usable to in one journey sow, cover the seed, and roll the ground. The rollers may be omitted, however, when desired, as I provide rear wheels, which are usable alone, set apart, or close together in combination with the rollers. In addition to seed, or instead of it, fertiliser may be added or used; but mention of fertiliser will, for brevity, be omitted. The general advantage of my implement as a whole is that it conduces to effective tillage in a labour-saving manner.

[NOTE.—The above extract from the specification is inserted in place of the claims.]

No. 23153.—18th July, 1907.—ARTHUR THOMAS BATE, of Wellington, New Zealand, Sharebroker (nominee of Walker Moseley, of East Dulwich, London, England, Electrical Engineer). Improvements in electric furnaces.*

Claims.—(1.) In electric furnaces, the division of the electric current into several circuits passing through several separate compartments filled with carbon granules and surrounding the crucible, substantially as described. (2.) In electric furnaces, a central crucible of fire-resisting material, a jacket surrounding such crucible, and leaving an annular space between, divisional pieces dividing such space into a number of separate longitudinal compartments, carbon granules filling each of such compartments, and means whereby the electric current may be divided so as to pass through the granules in each of such compartments, substantially as described. (3.) In electric furnaces constructed as described in claim 2, the provision of the conductor-wire leading to each granule-compartment with a regulating-switch and an ammeter, substantially as and for the purposes specified. (4.) In electric furnaces constructed as described in claim 2, a funnel-shaped opening in the bottom end of the crucible, and a carbon plug of inverted cone-shape placed within the crucible, and adapted to fit into and close such opening, and adapted to be pushed upwards from below, substantially as described. (5.) The improvements in electric furnaces, substantially as described and explained, and as illustrated in the drawings.

No. 23199.—25th July, 1907.—UNITED SHOE MACHINERY COMPANY, of Paterson, New Jersey, United States of America, a corporation duly organized under the laws of the said State of New Jersey carrying on business as Shoe Machinery Manufacturers, and having a place of business at 205 Lincoln Street, Boston, Massachusetts, United States of America (assignees of Arthur Bates, Arthur Ernest Jerram, and Joseph Gouldbourn, Engineers, all of Leicester, England). Improvements in or relating to awl-controlling mechanism for boot and shoe machinery.*

Claims.—(1.) In an awl mechanism, the combination with an awl and a driving member connected thereto of means controlled by a horn or other calipering device to “break” the driving connection at different stages of penetration of the awl, with or without co-operating means, to positively prevent further penetration of the awl. (2.) A constructional form of the combination claimed in claiming clause No. 1, wherein the connections between the driving member and the awl-carrier comprise a toggle that is broken by the movement of a horn or other work-calipering device, to negative or render ineffective a portion of the stroke of the driving member for the purpose described. (3.) In an awl-controlling mechanism, the combination of the shaft 2, lever 18, toggle 20, 22, awl-bar actuator 24, and awl bar 38 with means controlled by a work-calipering device for breaking the toggle for the purpose described. (4.) In an awl-controlling mechanism, the combination with mechanism for driving the awl that can be disconnected, of the stop 42, swing plate 44, arm 50, and vertically moving cam-plate 56. (5.) In an awl-controlling mechanism, the combination with a lever 18, awl-bar actuator 24, and a connection between them that can be disconnected, of a tripper 44 that is operated by the horn, or other calipering device, and works on the same axis as the lever 18 and awl-bar actuator 24. (6.) The improved device for varying the stroke of the awl in proportion to the thickness of the work, substantially as described and illustrated in the drawings.

No. 23211.—26th July, 1907.—GEORGE HUTCHINSON, of Warwick House, Christchurch, Canterbury, New Zealand, Inventor. An improved seed-box.*

Claims.—(1.) In a seed-box, a bottom composed of sheet-metal strips bent to form guides for directing seeds to seed-sowers located in spaces between the said strips, substantially as set forth. (2.) A seed-box comprising sides, a bottom constructed as claimed in claim 1 between the said sides and means for clamping the sides together, and ends to the seed-box, substantially as set forth. (3.) In a seed-box, sides made of wood, and a bottom constructed as claimed in claim 1 between the said sides, the edges of the said bottom entering grooves formed in the said sides, and bolts for clamping the sides together, substantially as set forth. (4.) In a seed-box, sides made of sheet metal, a bottom constructed as claimed in claim 1, between and secured to the said sides, substantially as set forth. (5.) In a seed-box, sides made of sheet metal, a bottom constructed as claimed in claim 1 between the said sides, and lugs upon the bottom adapted to pass through slots in the sides and to be clenched upon the outside thereof, substantially as set forth. (6.) In a seed-box, a bottom composed of a series of inverted V-shaped strips, spaced apart to admit seed-sowers, substantially as set forth. (7.) In a seed-box, flanges upon the bottoms of strips constructed as claimed in claim 5, for supporting seed-sowers, substantially as set forth. (8.) In a seed-box, a bottom composed of a series of strips approximately V-shape, the sides of the V being corrugated, curved or angled to prevent the strip from buckling when clamped between the sides of the box, substantially as set forth.
