AVELING AND PORTER'S ROYAL AGRICULTURAL SOCIETY'S FIRST PRIZE AGRICULTURAL LOCOMOTIVE ENGINE, FITTED WITH THEIR PATENT SIDE-PLATE BRACKETS.

These engines have been designed expressly for Steam Cultivation, Thrashing, Sawing, Pumping, and removing Agricultural produce. The boiler is unusually large, made of best quality plates, and tested up to 200 lbs. on the square inch; the fire-box is of Lowmoor iron.

It has a single steamjacketed cylinder mounted on the fore end of the boiler, to prevent priming and to economise fuel. The bearings of the crankshaft, counter-shaft, and driving-axle are carried by the side plates of the fire-box extended upwards and backwarks in

one

piece for this purpose. This patented arrangement is shown in the illustration, and is an improvement in the construction of engines of very great value, as it saves the boiler from the strain otherwise put upon it by the working parts, and minimises the risk from strained bolt holes. The driving-wheels are of iron; the engine is steered from the foot-plate, and in short the general characteristics of the Agricultural Locomotives are the same as those belonging to Aveling and Porter's Road Locomotives.

Each engine is provided with flywheel, governors, and powerful brake; a complete set of wrenches, screwhammer, firing tools, oil can, spare gauge glasses, studs for driving-wheels, extra safety valve, and steam pressure gauge are also supplied, free of additional charge.

Two of these engines, fitted with cranes, have been employed by the Commissioners of the Philadelphia Exhibition in removing and lifting heavy material.

The engine to which the Royal Agricultural Society's First Prize was awarded was one of Aveling and Porter's 10-horse power Locomotives, fitted with a single slide and ordinary link motion, and it indicated 65-horse power, with a consumption of three and one-fifth pounds of coal per horse power per hour, nine other ngines competing.

Not only was the First Prize for Road Locomotive Engines awarded to Aveling and Porter at the Royal Agricultural Society's Meeting, at Wolverhampton in 1871, but the Society's First Prize for the best waggon itable for Traction Engines was also given to them, after a very complete series of competitive dynamoetrical trials with waggons of all classes.

AVELING AND PORTER'S STEAM ROAD ROLLER, FITTED WITH THEIR PATENT SIDE-PLATE BRACKETS.

This machine is a special adaptation of Aveling and Porter's ordinary Road Locomotive to the purpose of road rolling, and in its design and construction every improvement suggested by long experience has been adopted.

The engine is carried upon four rollers of equal width, as shown in the engraving, the two hind ones acting as drivers, and the two in front as steering rollers. These latter cover the space between the two drivingrollers, and are made slightly conical in order that on theground line they may run close together

while leaving room above their axle for the vertical shaft which connects them to the engine, and which serves to support the forward part of the boiler; at the same time play is given to the vertical shaft for the rollers to accommodate themselves to the curved surface of the road. The machine can be turned round in little more than its own length, thus enabling it to roll steep hills without injury to the fire-box, while retaining the manifold practical advantages of the horizontal over the vertical boiler for locomotive purposes; amongst which may be enumerated absence of priming, economy in fuel, wear and tear, and much lower centre of gravity. It may be also noted as important features of these rollers that they are adapted for driving stone-breakers or other fixed machinery most economically when not required for rolling and for use as traction engines. They are managed by one person.

With each Roller the following free extras are supplied: feed oil can, box spanner and set of spanners, screw-hammer, two gauge glasses and washers, set of firing irons, and tube brush and rod.

Aveling and Porter introduced the Steam Road Roller in the year 1868 and have since then manufacture-d a great number of them. Among other places they are now working in London, Edinburgh, Liverpool. Manchester, Birmingham, Leeds, Sheffield, Bradford, Hull, Huddersfield, Newcastle-on-Tyne, Brighton. Darlington, Middlesbro', Blackpool, Kidderminster, Walsall. New York, Philadelphia, Chicago, Washington, Newhaven, Auburn, Hartford, Newark, Richmond, Bridgeport, St. Louis, Pittsburgh, Wilmington, Rochester, Berlin. Vienna. Pesth. Milan. Christiania. Stockholm. India. Canada. South America. Australia. West Indies.

The utility of road rolling is now generally appreciated, and when it is affirmed that a saving of 40 or 5 per cent. in the cost of road repairs results from the employment of steam rollers, there seems little need for

prefacing the description of the rollers themselves with observations upon the economy of using them. The reason of the great saving is obvious; the road being made for the traffic and not by it, the expenditure of material is diminished; the stones, instead of being left loosely upon the surface to encounter the grinding lateral pressure of the wheels, are forced by direct vertical pressure into the bed prepared for them, along with a binding material that fills up the interstices and-affording support for the stones-keeps them in position with one surface only exposed to the abrading action of the wheels; the whole coating is consolidated, and there remains a surface hard and smooth enough to resist the disintegrating action of rain or frost.

Municipal authorities, contractors, and others can be furnished on application with a pamphlet containing full details of sizes, weights, and prices of the various rollers made by Aveling and Porter, together with official reports from the several towns working them.

DESCRIPTION of an ORNAMENTAL PAVILION in Cast and Wrought Iron, designed by Thomas Jeckyll, Esq., 5, St. George's Terrace, Queen's Gate, London, manufactured by this firm, and exhibited by them in the main Building.

This Pavilion, which is intended for use upon a Lawn, or Ornamental Grounds, is 35 feet long by 18 feet wide, by 35 feet high to the extreme ridge. It is mounted upon a Dais of four steps. It has two Floors, the upper of which is reached by a Spiral Staircase. It is supported by 28 square columns placed 2 feet 6 inches spart.

The Ornament in the shafts of these columns is of a very rich and varied character. At a height of 7 feet 6 inches from the ground, a Transom Bar connects the columns. The lower Verandah is supported by castiron Brackets, firmly secured to the columns.

The outlines of these Brackets are in all cases alike, but the enrichment of their spandrils is varied by basreliefs, the subjects of which are studies from the "Apple Blossom, with flying Birds," "Whitethorn with Pheasants," "Scotch Fir with Jays," "Sunflower," "Chrysanthemum, Narcissus, Daisy and Grass, with a Crane and rising Lark," &c., &c. These brackets further support the Gutter and Cresting of the lower roof. The Cresting forms a wavy line which is surmounted at intervals by Fans richly carved, having for their subjects studies from the Rose, Honeysuckle, Chrysanthemum, Hydrangia, &c. Between each Column, ath the Transom Bar is a richly-carved pendent ornament forming an arch. Above the Transom Bar, Ll between it and the Gutter, are richly-carved open-work key pattern Panels, in which are numerous Ledallions of various designs, being studies from Butterflies, Bees, Birds, Fish, with many quaint and Sometrical patterns.

The upper floor is surrounded by a wrought-iron Balcony Railing, 4 feet high, of a light and severe design, Libiting how much grace can be produced by mere straight lines when they are properly arranged. The upper roof is supported in its turn by 20 columns of a similar design to the lower ones. These are ected by a Transom Bar, above which is a rich open-work fish-scale Panel supporting the upper Gutter, ith Cresting and Fans of a like character to the lower ones. The Brackets, however, upon these Columns of a different outline to the lower ones, and the spandrils are filled with many designs of a bolder character.

Between each Bracket, both upper and lower, is a richly ornamented Ceiling of a combined floral and geometrical pattern, the Chrysanthemum being taken as the type of its ornament.

The Roof, (the rafters of which are of wrought Tee iron,) is covered with zinc, in curved tiles, and is surmounted by an elaborately carved Cresting. The Fascia and pendent ornament beneath the Balcony, and overhanging the lower roof, is of a quaint and effective design.

One of the most important and novel features of this work is the Railing which surrounds the entire building. This is 4 feet 6 inches high, and is entirely of wrought iron. The Sunflower has been taken as the type of its ornament. The Railing is divided into 72 panels, each of which is occupied by a Sunflower 3 feet 6 inches high, the flower itself being 11 inches in diameter, having carefully veined leaves, six in number to each flower.

The appearance of this Railing is of a most striking and unusual character, and as a piece of workmanship it is believed to be unrivalled of its kind.

Want of time has prevented the Pavilion being finished in its entirety, but it is intended, when completed, to have a rich ceiling to the upper and lower compartments composed of cast iron Panels in bas-relief, and the upper floor will be approached by an ornamental Staircase in cast-iron. Whilst upon exhibition at Philadelphia,

the Ceilings and the upper portion of the walls of the Interior will be covered by a silken cloth having rich embroidery upon it, specially designed by Mr. Jeckyll, and executed at the Royal School of Art Needlework. In this the Horse Chestnut, Cranes, and various Birds form the elements of decoration.

THREE "GALLOWAY" STEAM BOILERS.

[graphic]

SECTION OF THE "GALLOWAY" BOILER FLUE AT BACK END, SHOWING (1875) PATENTED IMPROVEMENTS.

These Boilers are contributed by the makers at the request of the Executive Commissioners for the British Section, to enable them to exhibit a type and form of Steam Boiler of acknowledged excellence, and which is extensively used in Great Britain; and at the same time to supply steam to the engines in connection with the British Section.

This form of boiler is known as the "Galloway Boiler," and has been in use in England for upwards of 25 years. It is regarded as the most economical and efficient steam generator now made, having rapidly superseded the ordinary Cornish plain cylindrical boiler, with one circular flue running from end to end, and the Lancashire boiler, which is of a similar description, but having two flues instead of one.

The construction of the "Galloway Boiler" will be readily understood by examining the model which is placed in the British boiler house. It will be seen that in the cylindrical shell is placed an internal flue consisting of two furnaces at the front end, united into one back flue of an irregular oval form.
