Title: Improvements in Apparatus for Moulding and Pressing Dry Materials.
Inventor: LUCKE CLARA
Filed: 1897-12-29
Granted: 1898-12-29
Abstract: 30,718. Lucke, C. Dec. 29. Moulding fuel and starch. -Relates to presses for moulding dry materials, such as coal dust and starch, which are exposed successively to varying pressures in the same mould. The mould b<2> is detachably mounted in the intermittently-rotating disc f<4>, and rests during the moulding operation between the dies e<5>, d<3>, which have cylinders d<3>, d' with pistons, the rod of the former being connected to the lower arm of a lever o<3> oscillated from the shaft n and mounted upon an eccentric o' fast on the shaft n<1>, which is driven from the shaft n by a train of wheels. The piston-rod of the cylinder d<4> is connected to the upper arm of the lever o<3> by pivoted links o<4>, o<6>, &c. The cylinders d<2>, d<4> are connected to the hydraulic accumulator K, the piston of which is linked to the pivoted lever b<2> loaded with weights a<1>, a<2>, the latter being adjusted by nuts b<5> so that the weight a' is lifted some distance when the piston a ascends before being lifted itself. When the lever o<3> is oscillated and the dies begin to close on the mould, the pressure is governed by the weight a', but as the stroke is continued the weights a', a<2> control the pressure. The plunger n<4> ejects the finished articles, when the disc f<4> has been rotated to bring the mould in line with it, and delivers them to an endless band.

Title: Improvements in and relating to Driving and Brake Mechanism for Cycles, and other Vehicles.
Filed: 1898-10-04
Granted: 1899-05-06
Abstract: 20,891. Lake, H. H., [New Departure Bell Co.]. Oct. 4. Clutches; driving-mechanism ; brakes.-Relates to driving-mechanism for bicycles &c., arranged to give free cranks and allow the brake to be applied by back-pedalling. Reference is made to Specification No. 8833, A.D. 1895. The arrangement preferably adopted is shown in Fig. 16 as applied to a chain-driven bicycle, but the invention is also applicable to chainless cycles. The chain-wheel C<1> is mounted on a sleeve C rotating on ball bearings C<3>, C<5> and fitted with a sliding sleeve D. The sleeve D is connected to the sleeve C by a helical key c and groove d so that the movement of the sleeve C in one or the other direction traverses the sleeve D to the right or left. During forward driving the sleeve D moves to the right as shown, and its coned end engages in a coned socket E fixed in or formed on the hub A. When the pedals are held stationary, the cones are disengaged and the wheel runs free. Back-pedalling causes the sleeve D to move to the left and engage in a coned socket G carried by a boss F the rotation of which tilts a lever L and opens a split brake band k so as to force it into contact with the inner surface of a brake drum H fixed to the hub. The band k is prevented from rotating by engagement with lugs fixed to a plate I held stationary by connection with the frame. A spring band M fixed to the sliding sleeve D retards its movement so as to prevent the cranks from being free except under reasonable pressure. The projecting edges of this band engage shoulders on the cones E and G when the sleeve D is in the extreme positions. In a modification, the cones on the brake side of the mechanism are replaced by teeth carried by the boss F and the sleeve D. In another arrangement, the sliding sleeve D is connected to the sleeve C by a feather and keyway, and carries a helical rib engaging with a groove in the hub.

In the arrangement shown in Fig. 3, the support consists of four metal &c. strips a, a<1>, c, c', hinged at b, b<1>, d. The strips c, c' have projecting ends c<2>, c<3> which act as stops. The ends a<2>, a<3> of the strips a, a' are twisted at right-angles to engage the pedal as shown. When constructed for use with a rat-trap pedal, the ends a<2>, a<3> are lengthened to project through openings in the side plates. The support may be closed up as shown in Fig. 4. Fig. 8 shows a modification, in which a vertical strip a, shaped at the top a<4> to receive the pedal, is fitted with folding legs c, c<1>.

Title: Improvements in the Manufacture of Compound Ingots.
Inventor: COSGRAVE SYLVESTER ALPHONSE
Filed: 1899-12-12
Granted: 1900-01-27
Abstract: 24,719. Cosgrave, S. A. Dec. 12. Ingots.-Compound ingots are obtained by running molten metal, such as high-carbon steel, into a mould 1 provided with a core 3, and then removing the core from the hollow ingot 6 thus formed, and running in molten metal of a grade different from that of the metal first cast. The metal first cast is allowed to cool sufficiently to allow the core and mould to be removed from the base-plate 2, and the hollow ingot 6 may then be reheated and placed upon a base-plate ready to receive the second cast. In order to facilitate the removal of the core 3, it may be provided with a lifting-rod 4 attached to a plate 5 which is situated beneath the core and fits within a recess in the base-plate 2. The core 3 is formed of, or coated with, a flux, such as silica, or a deoxidizing-material. such as carbon ; a fluxing of the inner surface of the metal first cast may, however, be effected, in any suitable manner, after the removal of the core. According to a preferred method of casting the compound ingots, the second casting is effected by running the metal into the mould from below, the core being removed during the process of casting.

Abstract: 12,196. Greig, R. M., and Jamieson, J. July 6. Cutting-machines for paper.-Relates to clamping-apparatus for guillotine cutting-machines, and comprises improvements on the invention described in Specification No. 2362, A.D. 1881. The clamping-bar N is brought down to the paper by operating a treadle connected with the shaft Q. The machine is then started by disengaging the trigger A from the stud M. This allows the spring S to close the friction clutch V, while at the same time the rod G rotates the vertical shaft E and brings about the engagement of the toothed blocks H, H<1>. The block H is connected by the rod L with the weighted lever K, and the block H<1> is mounted on the shaft Q. The blocks being engaged, the lever K operates the clamping-bar N as soon as the crank-pin 0 is displaced by the movement of the wheel P. After the cut has been made, the knife returns to the top position, the stud M engaging the trigger A and disconnecting the clutch mechanism.

Abstract: 12,258. Lepore, F. M. July 6. Fire - escapes; alarms, fire.-Consists of an endless wire rope ladder 39, passing round a drum 26 at the top, and hanging with its free end through a window or the like. Guide-pulleys 41, 43, and 44 keep the ladder clear of the walls. A person wishing to descend steps on one of the rungs of the ladder, and regulates the speed of descent by pulling the brake rope 36, which acts through a compound lever 33,30 on the brake strap 28. When not in use, the rope ladder is stowed away above a trap door 7 in a cabinet 3 fixed above the window, a few feet of the free end of the ladder being left hanging down. When required for use, the free end of the ladder is pulled down, and this liberates the catch of the trap door, and allows the door to fall down and deliver the rest of the rope ladder. As the trap door falls it strikes a lever 18, which liberates the spring mechanism of an alarm bell.

A guard 43 encloses the floats 41, and beams 42 are fixed in the tank to aid in stilling the water. An auxiliary tank 51 can be put into connection with either the collecting and discharge tank 56, 57, 58, to increase their capacity when weather conditions render it desirable. In a modified form, the collecting and discharge tanks are circular and concentric, the former being in the centre and being filled through funnel-shaped collecting - passages. Another modification, adapted for erection in a creek &c., is also described, with inclined adjustable doors to regulate the inclined floor of the inlet for the waves.

Abstract: 13,263. Gutensohn, A., and Price, H. H. July 23. Metals, extracting; ores, roasting.-Sulphide ores of all kinds, such as pyrites or sulphides of copper, zinc, lead, &c., or artificial sulphide products, such as concentrates or mattes, are treated to eliminate the sulphur by (1) crushing, (2) mixing with carbon and with sodium sulphide or with materials which will produce the sulphide during the operation, (3) heating to a temperature below incipient redness, and (4) exposing the mass freely to air to effect its oxidation and burn off the sulphur. The product is now suitable for extracting gold, silver, &c. by known methods. The Provisional Specification states that, instead of sodium sulphide, suitable calcium or magnesium salts may be used, but the sodium salt is preferred.
