WILLIAM BRADY, OF MOUNT JOY, PENNSYLVANIA.
IMPROVEMENT IN DRAWING-KNIVES.
Specification forming part of Letters Patent No. 121,246, dated March 5, 1872.
I, WILLIAM. BRADY, of Mount Joy, in the county of Lancaster and State of Pen nsyl- Vania, have invented certain Improvements in Drawing-Knives, of which the following is a specification The nature of my invention consists in making the backs and handle-ends of each class of drawing-knives, however curved or differing in size, in a separate piece from that of the blade or cutting-portion. A sunken portion in the back, to receive the blade flush with the sides, is made and perforated with screwthreads cut in at regular intervals. The cutting-blades are out out of steel-plate, made to match the back, with like perforations countersunk for the screws and heads, by which the blades are fastened to the backs, of a uniform size, shape, and perforation to fit, so that extra blades of any number can be sold with the implement; thereby not only repeatedly utiliz in g the same back and handles after the cuttin gblade is worn outwhich is otherwise cast away as useless at a waste of more than half the material-but it also facilitates the grinding of curved blades, and affords the means of producing a more uniform temper, and consequently a superior cuttingblade, than when made as heretofore.
The accompanying drawing illustrates the nature of my invention, so that any one skilled in the art wili be enabled to make and use the same without further description, as the same holes, and wooden handles H on the ends. Fig. -2 shows the steel blade or cutter G, with the perforations countersunk for the screw-heads Fig. 3, the back and blade combined, showing the screw-heads flush with the cutting-blade 0 ready for use.
I am aware that separate cutters have been used on planes or .planers, and otherwise; I therefore, do not claim the cutting-blade sepa rately and distinct from the two-handled back. Being for years extensively engaged in the manufacture of edge tools, I am not aware that drawing-knives or any twohandled implement for shaving wood or the like, however shaped, was ever before known or used, made in the manner specified or substantially like it.
I claim as my invention, and desire to secure by Letters Patent- As an article of manufacture, a drawingknife, constructed as and for the purpose specified.
WILLIAM BRADY.
