501 & 506 Great Western Railway Company,
16 Lawrence Lane, Cheapside —Producer.Locomotive engine and tender, constructed at the Com-pany’s works at Swindon .
One of the ordinary class of engines constructed bytins Company for passenger traffic since 1847. It is ca-pable of taking a passenger-train, of 120 tons, at an ave-r age speed of 60 miles per hour, upon easy gradients. Thee vaporation of the boiler, when in full work, is equal^ to1000-horse power, of 33,000 lbs. per horse—the effectivePower, as measured by a dynamometer, is equal to 743.horse power.
The weight of the engine, empty, is 31 tons; coke andWater, 4 tons—engine in working order, 35 tons.
Tender empty, 9 tons; water, 1,600 gallons, 7 tons3 cwt.; coke, 1 ton 10 cwt.—total 17 tons 13 cwt.
The heating surfaces are, fire-box 156 feet; 305 tubesL7.59 feet.
. Diameter of cylinder, 18 inches ; length of stroke, 24inches; diameter of driving-wheel, 8 feet; maximumPressure of steam, 120 lbs,
The actual consumption of fuel in practice, with anaverage load of 90 tons, and an average speed of 29 miles,'^hiding stoppages (ordinary mail train), has averaged,o 8 lbs. of coke per mile.
A traversing-frame as used upon the Great Westernrailway, manufactured by Mr. G. Hennett, Bridgewater,or transferring railway carriages from one line of rails toaiy ,°*'^ ler parallel line. Short inclined planes areth a u ' :o eac ^ en< ^’ U P whioh the carriage is run upone flanges of the wheels, and which are there raisedof ar -? f t ^ le ra ^ s ^ means of a pedal. The main lines, ra “ s are usually lowered about an inch at the placeere the frame is placed, so as to diminish by about halfe amount what the carriage has to be raised,toe- A l0 A'i.°t a safety stop or switch fora siding, workedof th ■ signal by the same lever as the switch

503 Beckers, Gustavus Edward, Great WesternRailway, Paddington —Inventor.
Registered self-acting railway siding stop.
The object of this contrivance is to prevent accidentson railways caused by carriages or trucks getting acci-dentally out of sidings, and thereby occasioning collisionswith passing trains. Any carriage or truck can be pushedinto a siding, but cannot come out again without beingpurposely removed.
507 Lee, John, 103 Long Acre —Inventor and Patentee.
Full-sized under carriage, with Lee’s patent railway
breaks and axle-box. These breaks act directly from theaxle and box of the wheels with a wedge-power shoe,which bears against the wheels and rails._ The shoe hasa long surface bearing on the rail of 18 inches of com-pound adhesive metal. The inefficient breaks commonlyin use produce only five-eighths, or at most one inch, ofbearing or friction from the wheel on the rail, whichgreatly destroys the wheel tire and rails, and m insuffi-cient as a stopping power. The friction on the rail of theexhibitor’s break has the advantage of 18 to 1 over otherbreaks, by securing a certainty of biting the rails in wet,foggy, and slippery weather. This break being inde-pendent of the frame of the carriage, is free from theunpleasant tilting motion and mephitic smell of the oldbreaks. It is brought into action by one revolution of apowerful screw; another half turn of the screw throwsthe whole weight of the carriage upon the wedge block-bearing of the break against the wheel and rail, thusfreeing the tire of the wheels from friction, and raisingthe wheels clear of the rails one-sixteenth of an inch,further rise being prevented; thereby saving the expen-sive wear and tear of the wheels’ tire and rails—a matterof great consideration in the current cost of the stock ofrailway companies. These breaks can be brought intoaction on inclines, and relieved again without stoppingthe train.
Full-sized pair of Lee’s patent carriage-wheels, withaxletrees and axle-box. This patent invention is designedto prevent accidents when the axletree breaks—a circum-stance not of unfrequent occurrence with public convey-ances and railway trains, and is applicable to all kinds ofcarriages and machinery. When the axletree breaks thewheel will still retain its position, revolve, and carry onthe carriage with safety to any distance. The bearingsare more than triple the strength and utility of the solidaxle. The draught of the horse is greatly reduced by it,and the bearing is proof against the heating or settingfast of the wheel: it carries a large supply of oil to lastmore than twelve months, and is protected from grit, &e.These wheels can be readily detached and replaced again.It very greatly obviates the sudden unpleasant jerk causedby the wheels coming in contact with projecting sub-stances.
508 Crampton, Thomas R., South Eastern Sailway Com-
pany, 15 Buckingham Street, Adelphi —Inventorand Patentee.
South Eastern Railway Company’s London and Parisexpress locomotive engine, the “ Folkstone,” Crampton’spatent.
[This engine is suspended from three points at theends of the machine, the object being to insure theweights on the wheels being at all times the same, andthus producing the greatest amount of steadiness. Atten-tion is also called to the fact that the whole of themachinery is independent of the road : it is thus similarin its action to a fixed engine, and the risk of breakingthe crank axle, which frequently occurs in inside cylinderengines, is considered to be thus avoided.]
