New Paleyits and Mechanical Inventions. ' [July 1, 



To James Harvie, Engineer, late of 



iuipoilancc of lioiuliiijij iron in ])rcfcrcnco 

 to wcldiiii^, wliiuii cnnnot i)0 |iciforme(l 

 wiliiout the greatest liaziiifl ol' burning ;• 

 iiiid, jjowcvcr ingcnions llic late con- 

 trivances may be, tlie welding; difficnlty 

 has never been atlem|)le<l to l>e dis- 

 |jcnscd \rttl). Tlicio iiave been ail 

 manner of welding searfs proposed ; but 

 on c(>nsiderin<; tliat tlic thin part of those 

 scarl's (wlialfcvcr shape lliey may be) is 

 equally subject to the same beat as the 

 thick part, consequently must be de- 

 stro3e(l |iio\i(li<l the lliick part is suf- 

 ficiently hot to weld, — and us to the 

 clinching the shank of t!ic anchor 

 ilirongh, and on the crown of the flukes, 

 the immense wiing or strain ancliors arc 

 liable to sideways, must make this very 

 «lahgerous, — the bonding two pieces of 

 iron and securely uniting them, must be 

 considered stiongcr than one piece of 

 tJic same size, even if u elded securely, 

 and not burnt. And to do away this 

 great danger, that has been so destruc- 

 tive to the lives and propeity of all na- 

 tions, is tiie object Mr. H. hopes to 

 obtain ; an<l, though the price should ex- 

 ceed from live to ten per cent, otiier 

 anchors which are made with all those 

 hazardsattached to them, independently 

 of their being made without faggoting 

 the iron, which is frequently done, time 

 will prove that anchors made on the 

 principle prepnscd will be loinid much 

 superior to the present mode of making 

 them. 



To Andrew Timhreli,. of tie Old 

 South Sea House, London, merchant ; 

 for an Improvement of the Rudder and 

 Steerage if a Ship or Vessel. — 

 Dec. 2-2, l«-20. 



'i'his invention Cf)nsists in a flap or 

 shutter applied to each side of the stern- 

 posi, or other after-part of a vessel, in 

 iucli maimer as to fall over against the 

 rudder, and cover the spaces between 

 the forepart of the ru<lder and tlicafter- 

 part of the stern-post (oeeasioned by the 

 jientles and gudgeons on which the 

 rudder is hung), for the purpose of pre- 

 venting the action of the water against 

 the lore-part of the ladder when the 

 vessel is moving forward. Tlie bolt, 

 pcntles, braces, flaps, or sbutlers. are 

 made of copper; but any oliier suitable 

 material or materials iiiay be used in the 

 manufactory of this invention; and in 

 lieu of bolls, penlies, and braces, the 

 flaps or shutters may be attached to the 

 siern-post by round hinges, through 

 wliich a bolt or roil, of any suitable ina- 

 tciiul, may puKS and act in a socket. 



Berbice, now of Glasgow ; for Im- 

 provements in the Construction of 

 jyiach'uies, commonlij called Ginning 

 Machines, and which are employed in 

 separating Cotton-wool from the Seeds. 

 Communicated to him by certain Per- 

 sons residing Abroad- — Aug. 18, 1820. 

 'J'liese improvements consist in the 

 application of shifting brushes to the 

 back of the rollers usually employed in 

 ginning machines ; and by moans of 

 which brushes the cottim, on passing 

 througii the rollers, in the operation of 

 separating it from the seed, is prevented 

 from being <;arried round the rollers, 

 whereby it has hitherto been snbjecteil 

 to great injury in its colour and iabric 

 And these brushes are to be constructed 

 and aOixed to the ginning machine, as 

 follows : — Prepare a piece of. black, 

 birch wood, or other hard wood, and let 

 its edge or thickness be one-half of an 

 inch, and its breadth two inches and one- 

 quaiter of an inch; and let it be of such 

 a length as to fil into the sj)acc between 

 the pinchers, whereby the rollers of the 

 ginning machine, to which it is to be ap- 

 plied, are held together. Closely till the 

 edge of the wood with bristles, after the 

 manner in which biushes are usually 

 manufactured; at the distance of one- 

 foiuth of the length of the brush make 

 an oblong mortice, seven-eighths of an 

 ii'.ch in Idigth, and one-fourth of an inch 

 in breadth ; in each end of the brusii sink 

 a brass escutcheon, one-sixteenth of an 

 inch below the surface of the mortices, 

 by passing through the escutcheon and 

 morti<e loiiiKi-heailed screw-nails, hav- 

 ing flat shoulders. Fix the brush to the 

 gin, . o as the bristles may come in suita- 

 ble contact with the rollers; and, when 

 necessary, from the biisiles being re- 

 duced in length, tlirough continued fric- 

 tion, shift the brushes by unscrewing 

 and screwing the nails before described, 

 so as the bristles may be continued at all 

 times i(£^ suitable contact with the 



rollers.
