Patent GB-189707979-A (GB)
Title: Improvements in Rotary Engines.
Inventor: MARTINDALE MONTAGU DURANCE
Filed: 1897-03-27
Granted: 1898-03-12
Abstract: 7979. Martindale, M. D. March 27. Steam &c. turbines. -Blades b, b<2>, curved in opposite directions, are respectively mounted on discs B, B<2> on coaxial shafts C, C<2>. The motive fluid entering by the nozzles a<3> passes between the blades b, b<2> and rotates the discs B, B<2> in opposite directions before escaping through apertures b<4> to the exhaust. The rods c<5>, c<6>, which connect the turbine shafts C, C' to the driving- shaft D<5>, are arranged as in Fig. 2, so that the oppositely-rotating discs B, B<2> drive the shaft D<5> in the same direction ; or an open and a crossed belt may be substituted for the shafts c<5>, c<6>. Cones for combining air or other fluid with the motive fluid, to diminish the temperature or initial velocity of the latter, may be adapted to the nozzles a<3> ; and a driving-shaft D<6> with abutment surfaces d<7>, d<8>, Fig. 3, permits of the transmission of the rotary motion of the shaft D<5>, while allowing for the reversal of such motion. In the engine illustrated, gas from the producer F<2> is forced, together with air, by the pump M to the accumulator N, whence the mixture passes to the explosion chambers A<2>. The spreading of the jets may be prevented by constructing the blades or buckets b, b<2> in the form of pipes or nozzles, and a governor is substituted for the pump M and the accumulator N when the engine is driven by a highexplosive compound. The admission of explosive compounds or of steam may, however, be c o n - trolled by spring valves actuated by tappets. The invention can be applied to motors forland, marine, or aerial purposes, and may be driven by air, water, steam, gas, or other motive fluid. The opposite rotary motions of the discs B, B<2> can, without conversion, be used for driving right o left handed screw propellers of vessels, ventilating- fans, blowers, or centrifugal pumps, or for driving dynamos, the field magnets being connected to the one rotary disc B, and the armature to the oppositely-rotating d i s c B<2>. The details of construction may be modified.

Granted: 1898-03-05
Abstract: 8179. Willbur, J. M. March 30. Punching-machines for cheques.-Relates to cutting and punching apparatus for use in cancelling or mutilating cheques or the like when returned to the bank. The cutters or punches 20, Fig. 3, with V-shaped cutting-edges, are secured to a disc 15, attached to a backing-plate 16, which is provided with a threaded shank 17, fitted within the plunger 4, Fig. 1, of a hand cutting-press. A loose sleeve 18, formed with a base 19 having apertures for the cutters to pass through, surrounds the disc 15 and cutters and rests loosely upon the pile of papers to be cut. The cheques &c. rest upon a base-plate 5 retained in position by a latch 6. The plunger is actuated by means of an eccentricallymounted lever 7 and an antifriction roller 8 carried by the plunger ; the lever 7 is made in two parts, one sliding upon the other to an extent controlled by a chain 14. A shoulder formed on the upper part of the sleeve 18 rests upon the disc 15, and prevents the sleeve from falling away when the plunger is raised.

Abstract: 2665. Silk, W. S. Feb. 2. Ploughs.-Relates to ploughs having a reversible mould board and an adjustable share and coulter for turning the furrow to the right or left as desired. The plough consists of a suitable frame carried on two front wheels of equal diameter which are mounted on cranked arms secured in a sleeve which can be rocked by the lever x<2> acting through the link x<1> to adjust the depth of work. This sleeve is mounted in a rocking casting u which by means of a pin w on an arm w<1> of the sleeve w' can be secured in one of three positions to determine the desired positions of the carrying wheels.

Granted: 1899-01-14
Abstract: 5065. Belfield, R., [Davis, H. P.], and Conrad, F. March 1. Arc lamps.-The solenoids, cores, and dash-pots of alternating-current lamps are supported yieldingly, to reduce the production of noise. The solenoid 30, Fig. 2, and iron rings 31<b> are supported by insulating-rings 31, 31<a> in a metal frame 32, which has slots 32<a> engaging parts of the lamp frame, and rests on a felt cushion 33. The core 23 consists of sheet iron rolled to form a tube which is secured to a split disc 34, carried by a spring 36 and a top-plate 35, a felt cushion 37 being interposed. The dash-pot 22, Fig. 4, moves on a piston 29, made of or faced with graphite, and supported by a foot 29<b>, which is held between two felt discs in a box on the frame of the lamp. The core 23 and pot 22 are hung from opposite ends of a regulating-lever 21, Fig. 4, the motion of which is retarded by the action of the spring 36 and the dash-pot, when the arc is struck. The regulating-lever is fulcrumed at 19<a>, co-axially with a brake-wheel 20 geared to a pulley 17, which carries a chain supporting the carbon-holders, the upper of which is weighted. The regulating-lever also carries a spring-pressed lever 26, movable to a limited extent in a slot 27, and a brake strap 24 is attached at its ends to the levers 21, 26 as shown. When not in action, the dash-pot end of the lever 21 descends, and the lever 26 rests on the shaft 15, slackening the strap so that the carbons are free to move together ; when in action, the solenoid, connected in series with the carbons, turns the lever 21 so that the lever 26 leaves the shaft 15 and applies the brake, to strike and maintain an arc. The parts shown in Figs. 2 and 4 are supported in a casing, below which rods extend to carry a reflecting-cover for a globe, at some distance below. These rods also guide the carbon-holders. The globe is supported by a netting suspended by springs from the casing. The lower carbon-holder 7<a>, Fig. 6, is loosely mounted on a rod 8, the carbon being guided by a stationary ring near the arc.

The saddle has a disc L with holes through which the bars pass to be operated on by parting &c. tools N bolted on a disc M pivoted on the saddle and operated by a handle M<1> or a lever M' to bring either set of tools into engagement with opposite sides of the bars. The tools consist of circular discs with radial cutting-edges, so that they may be easily sharpened. Screw taps, drills, screw-plates, or other tools which require the saddle to traverse, are mounted in holes in a turret 0 held between clamping-rings P on the saddle. The turret may also serve as a steady rest, and may be provided with adjustable stops.

Abstract: 3282. Craig, J. Feb. 14. Couplings with valves; couplings, disconnectible. -Consists of means for charging vessels or containers with air, steam, and hot water or the like under pressure, and is specially applicable for charging the heating-cylinders used with compressed-air motors, particularly those for propelling vehicles. The outlet tube 2 is arranged within the charging-tube 1, and carries a valve 4 which controls the admission of the charge.
