Description: |
| Munson & Philipp- patent attorneysThe separate staves that are assembled in circular form to constitute a barrel-body require to be dressed so that the adjacent or bearing edges in contact shall fit or conform with each other, and thus form a proper joint, which, in "tight work," must be a closely-fitting joint. Such staves must also be bent to impart to them a longitudinal curvature, which produces bilge-form. The dressing of their edges must therefore be an angular cut that slightly bevels their edges, so that they will fit together in a circle, and it must also produce a longitudinal cut that curves from one end to the other of the staves, so as to narrow their end portions, while their centers are left wide or projecting, which staves are thus suited to form a bilged barrel-body. The cutting-wheels for stave-jointers have heretofore been constructed with a face constituted by a straight line from the periphery to a point a considerable distance therefrom, and thence curved down to the inner circle or line of its cutter-carrying portion, and the cutters carried by this wheel have cutting-edges conforming to this shape. These improvements relate to a jointing machine for producing these curved and beveled edge cuts; and the invention consists in a cutting head or wheel, of which the cutter carrying portion is curved from its outer to its inner edge, and which carries adjustable cutters of like curved form, by which structure the stave-edges will be so jointed that a barrel produced from them will be of the required curved form at bilge, quarter, and chine to constitute a barrel of perfect shape, having tight joints that will not leak, and the cubic area of which will correctly gage by the scientific instruments for such purpose; in an improved stave holding and presenting mechanism co-operating with said cutting-head; in an improved means for operating the stave clamps, and other details of construction, all of which will more fully hereinafter appear. |
