Fourth. In order to facilitate the fabrication of these pens, and to give them such a degree of truth and regular goodness in their formation as is unattainable by the use of pen-kuives, or any other kind of instrument heretofore adopted as a substitute for cutting them by hand, I take two pieces of steel, of a scantling size, of about three-eighths of an inch by two-eighths, and of about one inch or inch and a half in length, as I think it necessary. These I fix in a frame by the side of each other, having between them, on the two of their broadest’ sides, a thin piece of steel, of the same size in its width, and about the thickness, of a fine watch-spring, and in its length considerably above the length of the two before mentioned pieces between which it is fixed, this I call the lancet, or that part of the intended apparatus or machine which cuts the slit, and lets down the ink in the mouth of every pen, and the point, or cutting extremity, is made of a shape I find best to answer in practice, and is sharpened with an edge both as thin and regular in the middle of the flat substance as possible, because on this regularity and thinness depends both the fineness of the slit and its centrical adjustment in the pen!s point. When these component parts are properly and accurately fitted to each other, by filing, grinding, &c. on those sides in contact, and also fitted into a frame, in which they are fastened by a screw, so calculated as to either fasten, or occasionally release then, they are then ready to receive their prwper form on those ends or extremities meant to act, and form the pen’s mouth; to effect which, these ends of the scantling pieces are filed upon the bevel, or diverging from each other on the inside, so as to form an open mouth, to the extent in length up the pieces to any distance which may be found necessary for the intended purpose; so that when these pieces are again brought into contact
OR
on the fitting sides as before, the mouth formed will be of a triangular shape, which, when sloped or sharpened eft” on the backside, will exactly represent what is called a parting tool for carving and engraving of wood. These pieces of steel are then hardened, and properly tempered, so as to be capable of receiving and retaining » sharp cutting edge, and when that is done they are fit for use. The other thin piece of steel ab’ove described, and termed the lancet, is also sharpened in a proper form, like a chissel, or otherwise, as will best answer, and then put into its place between the Scantling pi«*ro, 9s before described^ having the extremity of its blunted cud above the top ends of the side pieces between •which the said lancet is confined, so that when the whole is fixed, as before stated, in the frame, and fastened with the screw, the lancet can be’ tapped down with a hammer at pleasure, and rendered capable of a nice and accurate adjustment when applied’to use. This method of fixing the lancet between those pieces, which cuts the chaps and forms the mouth of the pen on each side of the slit, is of great consequence, and it must always cause both the chaps of the pen’s point to be exactly equal in width from the slit. This frame and pieces, as above, being thus mounted and equipped, the whole is fixed or connected to the slider or ram of a small fly-press, such as is used for cutting and stamping in the common way of other manufactures, and which I need not therefore describe. This being done, I place under the lower or cutting point of the instrument a piece of very hard wood or metal, which is made on its upper surface, facing the cutting tool, of a shape either concave or convex, like a reed or a flute, to receive the half or a segment of the quill, either with the
concave
concave or convex side uppermost, as I may find it best iu practice. This I call the bed or anvil on which the quill is laid when in the act of being cut and shaped into a pen, and which bed or anvil is cut, or receives its counter shape, so as to exactly correspond and fit the dotting part, as above, by a blow or cutting stroke made by the instrument itself, so that there cannot be the smallest error in their contact when in use, and which properly will cause a clear and not a ragged cut always to be made upon the quill. This bed or anvil is also fixed and held in its place by being driven tight into a horizontal groove in the bed of’a cutting press ; so that when the contact with the cutting tool shall slacken •and become blunt with use, a small blow made”by a hammer, or being forced towards the cutter a little by a regulating screw, ‘the next blow or cut made by the press will renew’the contact, and make good this defect ; and by this means, added to the ready manner in ‘which the pieces of steel which form the mouth and the lancet also may be sharpened when taken out of the frame; the engfae can be continually kept in a state . of perfection with a little trouble. When the apparatus is thus equipped for action, and the rnm or slider of the cutting press lias been limited td its motions, by a proper stop, the lancet may be so adjusted by the tapping of a small hammer as to just cut through the thickness of the substance of the quill, and no farther; and it must be bore observed, that the ends of the pieces which cut and’ form the shape of the pen must be as nruch’shaptd upon the bevel as to cause the operation of the cut to finish at the point of the pen, and not at tiic. •bxn»dcrs of the point, because in the latter case the point of the lancet would have of necessity to pass as far beyond the thickness of the quill as the extra motion for finishing the mouth would require, and by which the two chaps of the pen would be distended by the thickness of the lancet’s taper form, and consequently receive such a false cut as to leave the chaps with a hair point each, lu making- pens by this instrument I do not mean in general to nib or cut the point square and clean by ‘ the operation of cutting the mouth and producing the capillary slit, but I intend rather, when the parts of divided quills, as above described, are cut into lengths, they shall be cut both square and clean enough to answer for the point; and in which case it must be obvious, that by forcing the quill when in the operation of forming the pen a little more or less near the junction of the triangular mouth of the cutters, the width of the pen’s point will consequently be increased or diminished in its dimensions, so that by a nice adjustment in this respect I $ball be able to cut the point broader or narrower at pleasure; and by so doing I can cut pens, calculated for every kind of hand, with strict accuracy; and also by canting the bed or anvil on which the quiil rests, either to the right or left from a right angle with the centre of the cutter, I can form pens with points a little out of the square, either way, for such as are used for ingrossing, and other particular purposes.
