No. XIX. Becent Patents. To GEORGE FREDRIC ECKSTEIN, of High Holborn, London, for certain improvements in Cooking Appa ratus. THE improvements proposed in this patent consist of a combination of implements or utensils for cooking, which are capable of being packed together in so small a compass as to become perfectly portable: the grate and fuel, with all the necessary articles for roasting, boiling, baking, frying, broiling, stewing, and steaming, being contained in a box something less than two feet square; the apparatus being thus rendered of casy transportation, is peculiarly convenient for the use of the camp or the traveller. The external appearance of the case containing the whole of the cooking articles in a travelling state, is merely that of a square chest with two handles. On the lid being unlocked, its sides may be thrown open by withdrawing certain pins or bolts, passed through staples, which hold the sides and ends together. The two ends and lid of the box having been removed, the sides, which fold upon hinges, are laid down level with the bottom, forming a flat board; into this, six legs are screwed; after which the band is inverted, and thus a dining table is produced of about six feet long by two wide. The lid of the box, with four legs screwed into it, forms a stand, upon which the apparatus is to be placed for the purpose of cooking, as seen in back and front views, Plate I. figs. 1 and 2. Fig. 1, exhibits the side and front of the portable kitchen in operation. It is externally formed by two cases or screens made of sheet iron or copper, enclosing a fire grate and oven; a joint of meat is seen roasting, and also a kettle on the top for boiling or steaming. Fig. 2, represents the other side and back of the apparatus with the oven door open, into which a small kettle may be partially introduced, as shewn, and also a stewing stove with a sauce-pan over it. The fire-place is made of cast and wrought iron, and is intended to burn charcoal; but when sea-coal, coke, or wood is employed, it may be found necessary to suffer the smoke to discharge itself through a pipe, seen in fig. 2. passing over the oven. If this apparatus be used in a dwelling, and fuel be employed which emits smoke, the pipe must be placed near to, or in the chimney; and if used in the open air it must be so situated that the mouth of the pipe cannot be choaked by the wind. The heat emitted from the grate with a small fire will be found sufficient for cooking with tolerable expedition: that is to roast in front, Grimshaw's, for Flat Ropes. 8 to bake behind, and, at the same time, to boil a kettle, and saucepans above. The fuel is to be supplied through an opening on the top of the screen, and the heat may be regulated by shutters. A box jack is shewn in fig. 2, to which the spit may be attached, so as to keep the meat turning. There are about ten sauce-pans and kettles of various sizes suited to different culinary purposes, the whole of which pack together with the apparatus as above, and the screens slide into each other. This apparatus is principally designed to form part of the equipage of a camp, the employment of which, however, in time of peace, must be extremely limited; for travellers on expeditions of discovery, it might be found convenient and useful; or, also, for what are termed gypsying parties. We have much pleasure in stating from our personal knowledge, the complete effect of its operation, having, upon one occasion, formed part of a company of six, when a military officer and his servant cooked for us, in this portable kitchen, a very excellent and abundant meal of roast, baked, and boiled meats and vegetables. Inrolled, November, 1821. To JOHN GRIMSHAW, of Bishopwearmouth, in the County of Durham, for an invention of a new and improved method of Stitching, Lacing, or Manufacturing of Flat Ropes by means of certain Machinery connected with and Wrought by a Steam-engine, or other Rota tive Power. FOR the better understanding of this improvement, the patentee describes the modes usually employed in the attachment of several ropes together, for the purpose of making flat ropes, or rope bands, such as are employed in drawing weights up the shafts of mines, &c., See Harvey's patent for improvements in the manufacture of ropes and bells. Vol. 11. page 6. of this Journal. Flat ropes are made by placing several round or ordinary ropes side by side, in a parallel direction, and fastening them together by a small cord passing through the ropes, (called lacing), which is generally done in a diagonal direction, cross and cross. For this purpose the several ropes called the strand are confined in a pipe or case, and being there perforated by a needle, the lacing cords are passed through and drawn tight. This is sometimes done by manual labour, but more frequently by a sort of engine in which the strand of cords is passed step by step a short distance forward, and the piercers or needles, on opposite sides alternately forced through the several cords by levers worked by toothed wheels; after which, the lacing is introduced by hand, and then drawn tight, so as to effect the attachment by successive diagonal stitches until the whole length of the strand is united. There are various ways of performing the three operations of piercing the holes, drawing the lacings through, and measuring the distance of the stitches; but all of them have been, as the patentee conceives, heretofore effected by manual labour, the distances of the stitches from each other, and the drawing of the lacing being left entirely to the discretion of the workman. The particular object of this patent is to perform the above operations by the power of a steam-engine, or · other first mover, which shall communicate a rotatory motion to certain toothed wheels of a machine, and thus, advance the strand of ropes progressively, and regularly, by which the distances of the lacing holes will be |
