oscillation and vibration of the trains in passing, and thesmaller number of hands required to keep this portion ofthe line in order, are said to be satisfactory.
No. 638, p. 246. Ebbw Vale Company, 83 UpperThames Street, London , and Abergavenny , Manufacturers.Sections of railway bars of all the forms used in railways.The Prize Medal is awarded to this exhibit in considera-tion of the facilities it affords for the comparison andstudy of the different forms of section, which have beendevised for giving strength and durability to railway bars.
No. 645, p. 247. The Cwm Avon Iron Company.Railway bars, 70 feet in length. The award is made forskilful workmanship.
No. 643, p.247. W. Baines, Birmingham , Inventor.An improved railway switch, in which the tongue is formedto pass under the upper flange of the fixed rail, by whichexpedient the point is prevented from rising, and thecarriage is made to pass more easily upon the new line.The switch is so formed as to have a broad base for itsbearing on the chairs, and it is made so much deeper thanthe main or fixed rail, that the lower flange of the switchpasses under the lower flange of the fixed rail. Twoadvantages result from this. The flange of the switchkeeps the tongue, when closed, from rising, and anystones or dirt which may fall between the switch and railare swept, as it closes not against the main rail, but underit; thus closing without risk of impediment from dirt orrubbish. The bearings of the switch are also placed alittle aside of the bearings of the rail, in order that anystones lying on them may in the same way be swept clearoff, and not be caught, so as to prevent the proper closingof the point.
No. 600, p. 243. Charles Young and Co., Inventorsand Manufacturers. “ Simultaneous-acting level-crossinggates for railways.” Serious accidents have arisen fromthe inability of the policemen in charge of level-crossingson railways to open in time all four gates to give passageto an approaching train. Messrs. Young’s gates are hung
on posts so set at the four angles of a square or a rhombus,that they close either across the line, and leave the roadclear, or close the road, and shut off all approach to theline. By a very simple and obvious connexion beneaththe ground between the heels of the several gates bymeans of iron rods, the motion of any one is accompaniedby the corresponding motion of the other three divisions.The policeman has not, therefore, to open and close eachof the four in succession, but by simply acting on one, heproduces simultaneously the required movement in all.The advantages arising from this arrangement, which isavailable either for straight or oblique crossings, areobvious, while cost of construction and maintenance isincreased only in a small proportion.
No. 552, p. 242. C.DeBergue, 9 Dow gate Hill, Inventorand Manufacturer. Patent station buffer. Mr. DeBerguehas aimed at producing a station buffer, which shouldoffer to a train impinging upon it a gradually increasingresistance through a long space, thereby absorbing thevis viva of the train gradually, and without shock of thecarriages upon one another; and he lias sought to do thiswithout the aid of a spring, the recoil of which, whenpowerfully compressed, might be attended with danger.In his station buffer the train impinges on the end of along stout beam of wood, slightly tapering from one endto the other. This beam has its smaller end fitted toenter a strong iron box or case. The force necessary todrive this taper beam into the case continually increasesas the larger end approaches the case, or as the woodmust be more and more compressed to enter the case.At the same time the beam, when driven in to any pointby the impact of a train, remains fixed there, having notendency to fly out or return to its first position. All theinjury which may be produced by the recoil of a power-fully-compressed spring is thus avoided, while on theremoval of the carriage the iron case is easily unscrewed,and the beam of wood loosened and drawn out to assumeits ordinary position.
