130 Judge, Thomas, Hampstead —Inventor andManufacturer.

Crank to pass the centres without the use of a fly-wheel or second steam-engine. Two cranks, intendedas a substitute for four bevel wheels used in turret clocks,to show the time on the dial.

Gas consumer, which receives the soot that passesthrough the burner, and destroys it by effect of the samelight.

Carriage steps. Self-adjusting spirit level.

mentary fulcrum for propulsion. The -water is thenthrown off in the direction of the axis or plane of thevessel’s course.

148 Paterson, Thomas, 15 Rupert Street, Haymarket—Inventor.

Model of a rotatory steam-engine. The invention con-sists in having each piston alternately fixed as a point ofresistance to the steam, and revolving as a moving power.—Provisionally registered.

131 Bickle, William, 18 Reading Street , Swindoyi—Designer and Manufacturer.

Working model of a pair of non-condensing steam-engines, which stands within the compass of a shilling,and weighs three drachms; made, with the exception, ofthe piston rods, of a fine white metal.

132 Eccleshall, Thomas, 2 Great Ruston Street North,Birmingham —Inventor.

Submarine propeller for steam vessels. Its purpose isto supersede the present means of producing motion bythe paddle-wheel or the screw, more especially the paddle-wheel.

An atmospheric propeller for the purposes of navigation.Its object is to increase the speed of navigable vessels,and to avoid the expense of the mast and rigging of sail-ing vessels; the delays arising from contrary winds, sothat a vessel may take her course direct; and to diminishmany of the present causes of shipwreck from shoals, &c.,when driven by stress of weather, as well as the risk ofiuman life attendant upon rough weather.

133 Day, Henry James , 27 Lower Northampton StretClcrkenwell —Manufacturer.Oscillating-cylinder marine-engine, exhibited for wor]manship. Diameter of cylinders, one-fifth of an incllength of stroke, one-fourth of an inch.

134 Hemming, George, 44 Lucas Street , CommercialRoad East —Designer.

Bird’s-eye view of a 145-horse power marine engine,shown at an angle, and drawn to a scale from workingdrawings; illustrative of a method of laying down ma-chinery or buildings, so as to avoid the expense of a model.

Bird’s-eye view of a 280-horse power direct actionmarine steam-engine, shown perpendicularly.

151 Haycraft, William Tutin, Greenwich —Patentee.Model of the “anhydrous” steam-engine; designed to

work with “ dry ” steam, by means of a “ separator ” ofnew construction, and a “ siccator;” to which is added anexpansion valve; this valve is specially applicable to loco-motive engines, from its readiness of action. The objectof this engine is to prevent boiler explosions. The cylin-der is provided with a steam jacket, which is essential toits operation.

[The object of this invention is to separate the steamfrom the water which generated it, and to apply it, in itsseparated state, to the working of the engine. For thispurpose an apparatus called a “ separator” is employed;another called a “siccator” is also used to keep up theheat of the steam in its separate state, otherwise it wouldcondense and lose its power.]

152 Elder, D., Royal Adelaide Steamer , Leith —

Inventor.

Model of an oscillating marine steam-engine, so ar-ranged as to dispense with the ordinary slide valves,eccentrics, &c.

154 Scott, G., 22a Winchester Street, City —Inventor.Boiler cleanser.

15(3 Jones, William , 4 Tabernacle Square, Finsbury —Inventor.

Model of an improved paddle-wheel, in which thepaddles rise vertically from the water, which preventsback water, and the consequent loss of power. The floatsmay be formed of sheet-iron, in one or more pieces, toslide into iron framework, and to move in plummer blocksfixed to the arms of the wheel, but not represented in themodel.

1 36 Stevens, John Lee, 3 Copthall Buildings —Inventor.

Models of a surface-propeller for steamers, &c.; of awater-wheel; of a registered omnibus ventilator; and ofRobinson’s registered safety-plug for boats, &c..

Drawings of registered improvements in umbrellas, fire-tongs, and shovel.

138

Richards, Thomas, 2 Kidd Street Woolv/ic iManufacturer and Designer.

Model of an apparatus for connecting and disconnectnthe engines from the paddle wheels, by a new methointended to dispense with the friction strap.

Models of propellers now in use, made to scale.

140 Keasley, W. H., 7 Smithfidd Bars —Inventor.

A new application of the Archimedean screw, for prpelling small vessels by hand. Applicable to canals, tlscrew creating no swell.

141 Smith, George, 49 Lime Street —Inventor.

Improved method of feathering the float of paddbwheels. The novelty is in the simplicity of its actioiincreased speed, and less straining of the vessel.

143 Hodgson, Robert, Ewell , near Epsom — Inventor.

Patent parabolic submarine propeller, for steam-shipThe novelty consists in the application of the hollow par;boloid, as the form of the machine to operate on the wateBy this means, its resistance, acting in parallel straigllines, is concentrated to the focus, which forms a me

158 Deane, C. A., 7 Henry Street , Hampstead Road —Manufacturer.

Working model of a high-pressure pedestal steam-engine.

160 Pym, John, 52 Threadneedle Street- —Inventor.

Model of a submerged paddle-wheel, for propellingvessels, to work wholly or partially under water. Thewheel has two shafts, one within the other; the inner oneis a screw, the arms of the wheel have blades at theirextremities, for a double-bladed paddle. On the arm orcentre of each paddle (within the main shaft) is a pinionworked by the screw shaft, giving to the paddle a rotatoryor propelling position at one part of the revolution of thewheel, and in a vertical or feathered position during ano-ther part of the revolution.

162 Colecrave, Francis Edw., Round Ilill, Brighton—Inventor.

Model of a cylinder, fitted with patent slide valve, fordiminishing friction.

200 Tuck, Joseph Henry , 22 Pall Mall —Manufacturer.Lariviere’s patent pneumatic governor for regulating

the speed of steam-engines.

201 Carstelr & Hoskinc, Perron Foundry and EngineWorks near Truro — Inventors and Manufacturers.
