Hydrostatic Chime and Clock-weight. 77 



the superintendence of our worthy President, I made 

 known the plan to him ; but the work was too far 

 advanced for its introduction there. Subsequently, at the 

 request of the President, I prepared the plan 1 now 

 exhibit for the last conversatione of this Society, together 

 with a brief description of my invention ; but owing to 

 the numerous objects of interest then exhibited, it was not 

 then alluded to. 



In proceeding to describe the self-acting hydrostatic 

 weight I may preface my observations by stating that it 

 can only be applied where there is a supply of water under 

 pressure. 



The accompanying sketch will assist in explaining its 

 action : 



The upper cistern A is supplied by two small services 

 from the street-mains, either of them being capable of 

 supplying the demand, and the use of two services is simply 

 to guard against any stoppage through accident to one. 



The ends of the service-pipes inside the tank are fitted 

 with the ordinary ball-cock and lever for regulating the 

 supply, and practically keeping the tank full up to the level 

 of the overflow-pipe. 



A little above the bottom of the cistern A a small pipe 

 is fixed with a stop-cock marked B, regulated by a micro- 

 meter-screw. From this stop-cock a small pipe conveys the 

 water towards the buckets D D D. At the outer end of this 

 pipe there is a small piece of vulcanised indian-rubber tube 

 attached C, by means of which the buckets are supplied. 



These buckets may be constructed as shown upon the 

 drawings, or of any other required shape ; their number and 

 capacity being regulated by the work they are required to 

 perform, and their driving-power made equal to the heaviest 

 weight required for driving town clocks and the striking- 

 gear of large bells and chimes. 



In each of these buckets the height and weight of the 

 water used is regulated and determined by an overflow pipe 

 E attached to the bottom of each bucket ; the top of this 

 overflow-pipe being lower than the upper edge of the bucket, 

 not only keeps a constant weight of water in each bucket, 

 but effectually prevents any waste or dropping outside. 



A small groove or channel F is made in each bucket as 

 shown, into which the end of the flexible indian-rubber 

 hose fits, thereby enabling each bucket to receive its supply 

 of water without splash or waste.
