J'u'nna Universal Exhibit io)i, 1873 



269 



main shafting for driving machinery in motion 

 will be supplied by the Austrian Commission, 

 and exhibitors will in no case be charged for 

 motive power supplied by the main driving shaft 

 in the Machinery Hall. 



The moving force will be transmitted by two 

 horizontal shafts of a diameter of 0*9 metre 

 (about 4"39 inches), and 120 revolutions per 

 minute is the speed rate. 



The exhibitors have to supply the pulleys for 

 the main shafts, as well as any other gear and 

 driving bands, at their own cost. 



Machinery intended to be worked will be 

 placed in the central gallery of the Machineiy 

 Hall. 



The preservation, cleaning, and oiling of the 

 main shafts will be attended to by the Austrian 

 General Manager, but exhibitors will have to 

 attend to the preservation and oiling of the gear 

 supplied by them, as also to the security of their 

 straps. 



Brickwork foundations in the Machinery Hall 

 must be built at the cost of the exhibitors, and 

 be finished and ready for receiving the machinery 

 by the 15th of March, 1873 ; but the brick 

 foundations and the stonework for engines and 

 steam boilers, &c., employed for setting in motion 

 the machines exhibited, will be constructed by 

 the Austrian Commission according to the plans 

 of the exhibitors. 



The main lines of pipes for water, steam, and 

 gas will also be laid by the Austrian Commission, 

 and the exhibitor has only to supply the con- 

 necting pipes with his machines. 



Coals from the best Austrian and Prussian coal 

 mines, and feeding for boilers, &c., supplying 

 steam engines, driving machinery in the Ma- 

 chinery Hall, will be supplied by the Austrian 

 Commission free of expense. Stokers will also be 

 provided for the steam boilers lent for service 

 in the Exhibition, or, if the exhibitor should 

 prefer to employ his own people, the wages of 

 the latter will be paid by the Austrian Commis- 

 sion according to the fixed tariff. 



Should an exhibitor wish to burn wood, he 

 will likewise be provided with it. 



The whole Exhibition ground will be drained 

 by a system of drainage pipes carrying water 

 and liquids to the Danube, and every measure 

 has been taken to have a sufficient supply of 

 water in all parts of the Exhibition. 



Water will be furnished at a pressure of about 

 24 feet at low pressure, and about 120 feet at 

 high pressure. 



Gas will be furnished by the Imperial Conti- 

 nental Gas Company at the usual pressure. 



Steam pressure generally at 5 atmospheres, 

 about 70 lb. to the square inch. 



Steam pressure in foreign boilers is not limited, 

 but they will be subject to the Austrian laws and 

 regulations. 



Single boiler-houses are being erected at the 

 rear of the Machinery Hall, about 40 feet 

 distant ; but a special boiler-house for British 

 boilers v/ill be built by the Austrian Commission. 



Plans furnished by the British Commission 

 for British boiler-houses, will be adopted if the 

 British Commission will undertake the execu- 

 tion of the same. The erection of British boiler- 

 houses is especially desired, in order to shew the 

 ingenuity and workmanship of British construc- 

 tion. 



Traction engines, locomotive steam carriages 

 for ordinary roads, steam omnibuses, and similar 

 kinds of self-propelling vehicles, will be allowed 

 to run about during the I'^xhibition, in some parts 

 of the Park and the Exhibition grounds. In fact, 

 traction engines, road rollers, self-propelling 

 steam carriages, steam omnibuses, and steam 

 pleasure carriages will be very welcome. 



There will be some woi'k of importance to be 

 done by steam road rollers, and, in case of any 

 work performed for the installation by traction 

 engines or road rollers, all expenses will be paid 

 by the Austrian Commission. 



In case of railway locomotive engines and 

 carriages being sent to the Exhibition, the rails 

 for them to stand upon must be provided by the 

 exhibitors, and it is very much desired that rails 

 from England should be sent to Vienna as ex- 

 hibition articles. 



There will be competitive trials with steam 

 fire engines, and the jury and exhibitors are in- 

 vited to send special engines for this purpose. 

 Such engines will be considered as objects of 

 exhibition, and, if lent for use, fuel and care 

 will be at the charge of the Imperial Austrian 

 Commission. 



There will likewise be special trials held with 

 agricultural machines and implements in fields 

 in the neighbourhood of Vienna, or in such 

 places as can be easily reached by the Exhibi- 

 tion railway. 



Agricultural machines will not be exhibited in 

 the Machinery Hall, but in a pavilion specially 

 built for that purpose. 



All machinc<5, &c., intended for the Exhibition 

 will be admitted to the Machinery Hall from 

 the 1st of February till the 15th of April, 1873, 

 inclusive, and must be set up by the 25111 of 

 April.
