52 Mr James Thomson on an Inqirovcd Tilting Apparatus. 



this apparatus, viz. : — the practicability of descharf/inj waggons 

 of different dimensions and different sized wheels upon the same 

 tilting-frame^ 



The advantages of the apparatus have been fully tested at 

 the Magheramorne lime-works in Ireland, where they were first 

 applied, and have since been in constant operation for the last 

 three years, discharging waggons of three tons with 24-inch 

 wheels, and waggons of only 20 cwt. and 20-inch wheels, with 

 perfect facility and expedition — the cost of each apparatus 

 not exceeding from dflO to £11 complete. 



Report of the Committee of the Boyal Scottish Society 

 of Arts, on Mr Thomson's Tilting Appca-atus for loaded 

 Waggons. 



Before the termination of the last Session, your Committee 

 held a meeting to consider the merits of Mr Thomson's im- 

 proved tilting appai'atus, and though they were well satisfied 

 with the principle on which the apparatus is constructed, in so 

 far as could be judged from the drawings, yet your Committee 

 deeming it expedient that they should have a report from the 

 persons using the machine in the locality named by Mr Thom- 

 son, deferred coming to a conclusion on the subject, and submit- 

 ted an interim report. Upon this they were instructed to corre- 

 spond with such persons at Magheramorne as might be consider- 

 ed qualified to give an opinion of the working of the machine. 



A correspondence was accordingly opened with Mr Maxwell, 

 manager of the lime-works at Magheramorne, and the accom- 

 panying letter, dated 21st October, contains Mr Maxwell's re- 

 port of the practical working of the apparatus. 



Your Committee have, therefore, now no hesitation in giving 

 a very favourable opinion of Mr Thomson's improvements on 

 this tilting apparatus, and they are the more strongly induced to 

 report thus favourably, from having lately learned that the im- 

 proved apparatus is now being introduced upon the coal-wharfs 

 of the Monkland and other canals ; and it is, therefore, humbly 

 suggested, that Mr Thomson merits the marked approbation of 

 the Society. All which is humbly reported by your Committee, 



James Slight. Com'ener.
