A25366	The making of rockets in two parts, the first containing the making of rockets for the meanest capacity, the other to make rockets by a duplicate proposition, to 1000 pound weight or higher / experimentally and mathematically demonstrated, by Robert Anderson.	Anderson, Robert, fl. 1668-1696.	1696 (1696)	Wing A3105; ESTC R1638	16,468	65

impossible ever to bring that way of shooting to be so exact and ready for use in all or any sorts of Guns as the common or usual way is by keeping the Requisites of Powder constant and elevating the Piece In the Complicating of Rockets whose Diameters are at any great distance we make use of Experiments of shooting made upon another Occasion and those Experiments serves sufficiently well but if we were to do them justly according to Art there should be two even Chased Guns of the same Proportion as the Rockets are of that is the Diameter of the exposed Rocket 2½ Inch multiplied by 6 is 15 Inches and those should be the Diameter and length of one of the Guns 4 Inches the Diameter of the other Rocket multiplied by 6 is 24 Inches which 4 Inches for the Diameter and 24 Inches for the length should be the other Gun or any two Guns in that Proportion For the Requisite of Powder take the Cube of 4 which is 64 as also the Cube of 2½ which is 15.625 divide the greater Cube Number by the lesser and the Quotient is 4 sufficiently near so the Requisites of Powder of these two Pieces are as 4 to 1 then take any reasonable Requisite of Powder for the 4 Inch Gun then take the fourth part of that Requisite for the Requisite of Powder for the lesser Gun discharge them both at one degree of Elevation and note their Ranges Their Bullets are to be of the same Metal and of the same likeness and both exactly fit In a Mathematical sence these Ranges should be equal but by Combination the greater quantity of Powder aggitates more upon the great Bullet than the lesser Requisites doth aggitate upon the lesser Bullet and that causes those differences the like when two quantities of Powder aggitate upon one Bullet it is Experience only that determines the matter Although strange things sometimes happens yet this we will Assert and endeavour to maintain that Mathematical Knowledg join'd with faithful Experiments will do greater matters than most Men commonly conceive Rob. Anderson Rocket Moulds are made by Mr. Cuggley just without Cripplegate Taper Bits for Rockets are made by Mr. Goode just within Cripplegate Rods for Rockets are made by Mr. Stateham in Token-House-Yard Lothbury All three right good Workmen PROPOSITION I. Of a Rocket-Mould LEt E M R D D H L E be a Rocket-Mould A B the Diameter of it viz. one Inch and half Z K 4 Diameters that is 6 Inches the height to be filled with Composition B E half a Diameter an overplus Z C the height of the boring 4 Inches and ½ or ¾ of the height of the Mould G F the Orifice one third of the Diameter of the Rocket half an Inch Z Y one sixth of the Diameter of the Rocket a quarter of an Inch the thickness of the Case D Y Z G C F Z Y D the bottom of the Rocket-Mould with the Needle to be put in and taken out R H a Pin of Iron to fix the Mould and Bottom together PROPOSITION II. Of the Rowler and Case of a Rocket MAke the Body of the Rowler nine Diameters in length and in Diameter two thirds of the Diameter of the Rocket and the Head of the Rowler of the Rocket the same Diameter let the Diameter of the Neck of the Rowler be a little less than one third of the Diameter of the Rocket because when opened with a Cone of Wood the Orifice of the Rocket may be just one third smooth and hard to endure the Fire Then the thickness of the Case will be one sixth of the Diameter of the Rocket which being well Rowled and Choaked the Case may be finished PROPOSITION III. Of the Composition for Rockets THE Ingredients which Rockets are Composed of are Saltpetre Sulphur and Wood-Coal mealed and passed through a fine Sieve First take the largest of Small-Coal made of Birch-Wood Secondly chuse the Yellowest Roch Sulphur Thirdly take Saltpetre put in a Brass Vessel to which put so much fair Water as will dissolve it put that Vessel upon the Fire when it boils scum it clean when the Water evaporates and consumes stir it with a Spatula of Wood to meal it what remains of the Saltpetre upon the Spatula and sides of the Vessel rub off with your Spatula of Wood then meal it and pass it through a fine Sieve A second way to Clarifie Saltpetre take a Crucible set it in the Fire put Saltpetre thereunto increase the Fire till the Saltpetre be Reduced to a liquid quality like Water when it boils take mealed Sulphur upon a Spatula of Iron and put it into the boiling Saltpetre so often repeated the Flegmy quality of the Saltpetre will be burnt away and the flame will remain as white as the Body of the Sun Then pour it into some very smooth Vessel which being cooled you may reduce it into meal These ways I have done for my Recreation but I usually take the cleanest Saltpetre to be found in Drugsters Shops and it does as well PROPOSITION IV. The Receipts for Rockets FOR an Inch an Inch and half and two Inch Rocket and for a White Fire take 2 Drams of Antimony 1 Ounce of Sulphur 2½ Ounces of Coal-dust 6 Ounces of Saltpetre and 8 Ounces of powder dust Casimer du Grand Art d' Artillerie Partie 1. Livre 3. pag. 145. Fill 4 Diameters and Bore 2½ For an Inch and half and two Inch and two Inch and half Rocket and a Yellow Fire take 1 Ounce of Sulphur 1 Ounce of Coal-dust 4 Ounces of Saltpetre or take 1 Ounce of Sulphur 1½ Ounce of Coal-dust and 4 Ounces of Saltpetre Casimer du Grand Art d' Artillerie Partie 1. Livre 2. pag. 99. Fill 4 Diameters and bore 3 or a little more And Daniel Elrich Der grossen Kunst Artillerie Zweiter Thei l pag. 54. at 19. Advises to take 1 Ounce of Sulphur one Ounce of Coal dust 4 Ounces of Saltpetre Again take 1 Ounce of Sulphur 2 Ounces of Coal and 6 Ounces of Saltpetre also take 1 Ounce of Sulphur 2½ of Coal and 6 of Saltpetre Johann Sigmund Buchner in Theoria praxis Artilleria Andere Thei l pag. 28. Weigh the Ingredients single put them into a wooden Bowl mix them very well together and pass them through the Sieve then your Composition is fit for use In filling Rockets of one or two Inches Diameter let them be filled at 6 8 or 10 times Charging and to every Charge 10 12 or 14 blows with a Mallet and betwixt every three blows turn the Driver a little in your Hand so the Composition about the Needle will be preserved Some of our Rocket-Makers cry up the Compositions of Woolverman and Nelson as though there was no Composition to be found like theirs and they are thus that falsly called Woolverman's is 1 of Sulphur 1 of Coal and 4 of Saltpetre and that of Nelson 1 of Sulphur 1½ of Coal and 4 of Saltpetre as they

FIre the Rocket in your Hand with with your port-Port-fire through it into a deep Water otherwise it will stick in the Mud it will Swim a little while but when the Strong Composition takes fire it will Dive and when the Strong Composition is spent it will jump up c. The Weak Composition being the last the Rocket for some time will Swim upon the Water and then give a Report This Rocket is all Solid To make a Rocket Charger LET the length of the Charger E G be one Diameter and half the breadth of the Charger H Z one Diameter and one third the length of the Neck of the Charger that slippeth upon the Handle B C two Diameters the breadth of that Ferril A B one third of the Diameter of the Rocket betwixt eight or nine of these Charges will fill a Rocket 4 Diameters You may cut the Charger A B C D H G Z A in Paper then it may be made in Copper Close A to D and B to C Sodder both ends together bring H G Z into more than half a round and A B and C D in a round put it then upon a Handle then it is fit for use To make good Coal for Rockets TAke pieces of a light dry Deal Board about 12 Inches in length and about the thickness of 2 Fingers or less put them into an Oven put fire to the Wood when they are burned enough take them out and put them into an Iron Brass or Eathern Pot close it well with a Cover that it takes no Air the Fire being extinguished beat it and pass it through a fine Sieve then it is fit for use If the Wood be not well burnt put it into the Oven again and so repeat your Work such Coal will make a Rocket fly very lively if not with two much Life Compositions for Reports   A B C D 〈…〉 Saltpetre 9. 4. 3. 2. Salt of Tartar 3. 3. 2. 1. Sulphur 1. 2. 1. 1. Take Sulphur 1 Tartar 3 and Salt-petre 9 grind these well together and dry them A few Grains of this Powder being fired will give as great a Clap as a Musket when it is discharged Dr. French pag. 171. Take any of these Ingredients under A B C or D mix them well together put a little quantity of that mixture into a Fire-Pan set it upon the Fire and in a little time it will give a great Report A further use of the Tables WHat is done in the 14 and 15 Propositions by taking the Cubes of the Diameter of the Bores of the Rockets may be done by the Tables in 2 and 3 or Tab 4. Thus look in the first Column for the Diameters of the Rockets viz. 2½ and 4 and against them in Column 2 and 3 I find 2 Pounds and 4 Ounces and 9 Pounds divide the greater Number by the lesser the Quotient will be 4 near enough so the Ratio of these two Rockets are as 4 to 1 and this is by the weight of the Rockets In the other Example I find 4 and 6 in the first Column and against them 〈…〉 Column 4 I find 76 and 256 Ounces of Composition for these two Rockets then divide the greater by the lesser the Quotient will be 3 and more which is the same thing as if you made use of the Cubes of their Diameters for indeed these Tables are made by the Cubes of the respective Diameters A Conclusion IF any one presumes to say they have Resolved the 14. Proposition before the Publication of this they might have been so kind as to put it into Practice for the Defence of the Nation If any say they can do it I desire them so to do That I may see my desires accomplished viz. Great Guns and their Carriages truly fortified and neatly made which would be great satisfaction however this may shew to the next Age what has been offered to this Iuly 25. 1696. FINIS
