JAMES F.VWOOD, 0F PHILADELPHI, PENNSYLVANIA. ff
Letters Patent No. 102,459, 4dated Apr/il 26, 1870.
The Schedule referred to in the'se Letters Patent and making part of the same.
To all whom it may concern:
` Be it known that I, JAMEs F, WOOD, of Philadelphia, Pennsylvania, have invented an Improved Gouge; and I do hereby declare the following to be a full, clear, and exact description ofthe same. My invention consists of a gouge, the blade of which is so formed that its cutting-edge, instead of being in the arc of a circle, shall coincide with a parabolic c'urve or with a portion of an ellipse or 4oval gure, so that the tool can be used for a class of work which has heretofore required several gouges of different sizes to complete.
In order to enable others skilled in the art to make and use my invention, I will now proceed to describe the mode'ot constructing and using'the same, reference being had to the accompanying drawing which forms apart of this specification, and in which- Figure l is a perspective view of my improved gouge;
Figure 2, a view of the cutting-edge;
Figure 3, a diagram, illustrating a mode of forming the gouge; and
Figure 4, a diagram showing the advantagesof my invention..
The blades of curved gouges have heretofore consisted of longitudinal sections of hollow cylinders or of sections of flattened orpther shaped tubes, the cuttingedges of such tools heilig regular in shape, that is, the portions of the edge of a tool on both sides of a centra-l point corresponding to each other in shape; it is necessary, therefore, for pattern-makers, cabinet-makers, and other workers. in wood to keep a stock of gouges having cutting-edges representing arcs of circles of different diameters adapted to different work.
In order to obviate the necessity of 'purchasing a costly array of these instruments, I so'form the blade A oi'a gouge that its cutting-edge shall coincide with, such a portiou'of an ellipse or oval that the portions of the edge onv opposite sides of a central pointshall be of diierentforms or degrees of curvature, it being preferable to makethe gouge so that its cutting-edge shall coincide with a parabolic curve, as in iig. 3, the formation of which will be readily understood without explanation.
An example of the advantages of my invention is illustrated on iig. 4, where H represents half of a box for making tapering cores to he used in molding tapering pipes.
To make a box like this with ordinary gouges is a matter of no little difficulty,- owing to the variation in size of theigroove a: throughout the length ofthe box.
.By my improved, gouge, however, the portion m en one side of the central point :v of its cutting-edge may be applied to the formation of the small end on of the groove in the box, and the operator, as he pushes the gouge toward the opposite end of the box, may gradually turn the tool in his hand until the portion w/ of its cutting-edge acts on the edge n of the recess :L1-of the box. 'It' will be readily understood byoperators in wood that my improved gouge may beused to great adv'antage in many other cases where a number of different sized gouges are usually required to complete the work.l
I claim as my invention anddesire to secure by Letters Patent- A gouge, so formed that its cutting-edge shall coin eide with a parabolic curve or a portionot` an ellipse, oval, or other equivalent form, for the purposel specified. l
In testimony'whereof I have signed my name to this specification in the presence of two subscribing witnesses.
JAS'F. WOOD.
