CM. A Method of commTinicaiing Rotatory Motion. By Che 

 valier Baader, First Counsellor of M'mes, and Director- Ge- 

 neral of Hydraulic Constructions to His Majesty the King 

 of Bavaria, (^c. &c. (^c* 



Sir, — 1 iJEG-leave to offer to the Society of Arts the plan of a 

 inecijanical invention, which I have esoi'iUed with success in my 

 own country, but which is not yet kiiov.n in this, nor published 

 any where. 



It is a method of communicating rotatory motion to a couisi- 

 ilerai)!e distance from the persoii or persons who turn the ma- 

 chine, and without the use of wheels or pinions, band-wheels, or 

 any other of the usual means, i made use of it in an hydraulic 

 machine to raise water from the foundations of houses, &c., the 

 workmen staiidir.J on the bank or firm ground, and giving mo- 

 tion to an axis with cranks placed over the water. 



I flatter myself that this invention will be found so miich more 

 worthy of your celebrated and patriotic Society, as its utility is 

 perfectly ascertained by the experience of a number of years in 

 <itrir?any5 and, as its application may also prove beneficial to 

 this country in many instances. 



I am", with perfect esteem, sir. 



Your most obedient humble servant,

Description of the Machive. (See Plate V.) 

 The two levers, A B, turning on the centres, CD, of the 

 moveable bars, E F, suspended on their centres, E F, attached^ 

 to the frame of the machine, having a turning handle, G, which; 

 connects their ends, H I, and being attached by cranks to the 

 wheel and axle, K L M, at their other cMtrcmities, communicate 

 anv rotatory motion given to the handle, G, to the wheel and 

 nxie, but in a reversed direction, as marked by the arrows, N O; 

 and tliis, without the use of wheel-work, band-wheels, &c. asj 

 hitherto done. 



• In the drawing of the machine sent by the Chevalier de Baader 

 to the Socit'tv, tiii< contrivance w?ts employed to communicate, 

 rotatorv motion given to the handle, G, by labourers standing 

 iipon the i)lntf(i;ni, P Q, of the machine, on the l>ank of a rcicr- 

 voir, &c. from which v.atef was to be raised, to the wheel and 

 axle, K L M, placed over the water to work pumps, &c. as re-
