deflection of the bearing springs. When the crane is coupled up behind a locomotive the motion just described is thrown out of gear. The jib is a straight wrought-iron lattice jib, combining the requisite amount of stiffness with the minimum weight compatible with safety. The radius of the jib is altered by means of a double chain and worm, and tangent wheel ; this arrangement not only forms an easy plan of obtaining the large power necessary, but the worm locks the jib in any required position. The turning or slewing motion is obtained through a set of bevil wheels and friction clutches on the crank shaft; and can be worked in either direction simultaneously with any of the three other motions. The friction clutches drive a vertical shaft which in its turn through a train of gear drives a turned roller running on the roller path, and situated at the foot of the jib. This motion being obtained entirely by the friction of surfaces and not through the medium of toothed gear on the base-plate, the risk of breakage due to careless driving is entirely avoided. The price of the crane Fig. 1 as above described, to lift three-ton loads at 14 feet radius, and proportionately lighter loads at longer radii with steam travelling motion, with iron jib, and boiler felted and lagged, Packed and delivered at Liverpool

£615 0 0 Set of duplicate parts for ditto, ditto, ditto

£15 0 0 Two other cranes exhibited by the same firm are each capable of dealing with loads up to FIVE TONS ; they are illustrated by engraving Fig. 2, and, although very similar in general appearance to the 3-tons crane

described above, they vary from it somewhat in detail. One of these cranes (No. 43) is fitted with all the four motions detailed above, whilst the other (No. 41) has only three of the four motions, the travelling motion being omitted. They are both mounted on PLAIN CAST-IRON CARRIAGES, with rigid bearings for axles, and are not adapted for running at very high speeds. The various operations are performed by exactly the same means as in the three-tons crane, excepting the travelling motion in which the pitch chains are replaced by bevel gearing, the whole of the parts being of course proportioned to the loads to be handled. The price of the crane, Fig. 2, as above described, to lift five-tons loads at 14 feet radius and proportionately lighter loads at longer radii,

£15 0 0 Price of the crane, Fig. 2, to lift five tons as above described, but not to travel by steam (No. 41) is 251. less. Cranes exactly similar to those exhibited have been mounted on gantries of sufficient height to allow of the free circulation of locomotives and rolling stock beneath them; many such may now be seen at work at Middlesborough Docks in England ; at Callao Harbour in Peru ; at the new Amsterdam Docks in Holland, and in other parts of the world.

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 5-horse power, with a consumption of three and one-fifth pounds of coal per lorse power per hour, nine other engines 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 dynamopetrical trials with waggons of all classes.

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

This machine is a spacial adaptation of Aveling and

Porter's ordinary Road Locomotive to the purpose of road rolling, and in its design and con. struction every improve 'ment 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 SA

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 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 wasliers, 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 manufactura 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, Brightor Darlington, Middlesbro', Blackpool, Kidderminster, Walsall. New York, Philadelphia, Chicago, Washingtor Newhaven, Auburn, Hartford, Newark, Richmond, Bridgeport, St. Louis, Pittsburgh, Wilmington, Rocheste Berlin. Vienna. Pesth. Milan. Christiania. Stockholm. India. Canada. South America. Australi West Indies.

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

[graphic]

prefacing the description of the rollers themselves with observations upo. 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.

Garden Chairs, Lounges, and Ta les of wrought and cast iron, in various designs, some of the lounges and chairs having canopies ; supplied for the gardens and grounds adjoining the Staff Quarters. 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 Cppt of which is reached by a Spiral Staircase. It is supported by 28 square columns placed 2 feet 6 inches

a 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 bass-liefs, the subjects of which are studies from the "Apple Blossom, with flying Birds,” “Whitethorn with Plasants,” “Scotch Fir with Jays,” “ Sunflower,” “ Chrysanthemum, Narcissus, Daisy and Grass, with a Crade 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 bjects studies from the Rose, Honeysuckle, Chrysanthemum, Hydrangia, &c. Between each Column,

math the Transom Bar is a richly-carved pendent ornament forming an arch. Above the Transom Bar, ell between it and the Gutter, are richly-carved open-work key pattern Panels, in which are numerous 1dallions of various designs, being studies from Butterflies, Bees, Birds, Fish, with many quaint and 23-vnetrical patterns.

The upper floor is surrounded by a wrought-iron Balcony Railing, 4 feet high, of a light and severe design, il biting 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 acted by a Transom Bar, above which is a rich open-work fish-scale Panel supporting the upper Gutter, - :! 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 beliered to be unrivalled of its kind.

Want of time has prevented the Pavilion being finished in its entirety, but it is intendel, when completed, to hare 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,
