edges of the crack trimmed or cut away, so as to widen the LOUIS NEWMAN. OF NEW YORK, N. Y.
CRACK-CUTTING TOOL.
Specification of Letters Patent.
Patented July 17, 1906.
Application filed November 8, 1904. Serial No. 231,935.
To all whom it may concern:
Be it known that I, LOUIS NEWMAN, a citizen of the United States, residing in New York, borough of Manhattan, and State of New York, have invented certain new and useful Improvements in Crack-Cutting Tools, of which the following is a specification.
Before appplying the paint or paper to the plaster of interior walls it is necessary to open or widen the cracks in the plaster, so as to permit the insertion of a sufficient quantity of plaster-of paris for the purpose of fillin said cracks, so that the paper or paint wil present a smooth and even outersurface. Heretofore this widening was usually done by means of a knife or similar tool, so that it was necessary to scrape one edge of the crack after another, thus consuming considerable time and causing great delay in the work of, painting or paper-hanging.
This invention is intended to obviate the disadvantages referred to and to'furnish to painters and paper-hangers a tool by means of which with one stroke of the same both are simultaneously crack sufliciently to receive and retain a filling ofplaster-of paris or other suitable material, so as to render the surface of the wall, and thereby the paper or paint applied to the same, smooth and even; and for this purpose the invention consists in the novel features and combinations of parts to be hereinafter described and claimed.
In the accompanying drawings, Figure 1 is a perspective view of my improved crackcutting tool. Fig. 2 is a side elevation of-the same. Fig. 3 is an end view; andFig. 4, a horizontal section on line 4 4, Fig. 3, through the cutting-blades.
Similar letters of reference indicate corresponding parts.
Referring to the drawings, A represents the handle, and B the knife, of the crack-cutting tool. The knife is fastened to the handle by means of a shank d, that is arranged at an obtuse angle of inclination to the cutting-knife B, said shank being inserted into the handle and firmly secured therein. The knife is formed. of two curved blades 1) b, which are directly interconnected at substantially the same angle at their front and rear ends, so as to form an elongated fusiform opening between them, the front end 9 having a slight forward inclination and being sharpened, so as to facilitate the insertion of the knife in the crack, while the rear end is preferably formed integral with the shank d. The inner edges 6 e of the curved blades are sharpened, while the outer edges f f remain dull, so that by moving the tool quickly along the crack both edges of the latter are simultaneously cut to a width corresponding to the distance between the curved blades and produce thereby a uniform widening or enlar ing of the crack. The blades being curved, as shown, adapt themselves to variations of the width of the crack. After the crack has been scraped it is ready to be filled with plaster-of-paris or other suitable material preparatory to painting or papering the same.
The cutting-blades may be made of toolsteel and sharpened at their inclined front edges, as well as at the inner edges, so as to permit the insertion of the tool into the crack and the quick and smooth cutting of both edges of the same preparatory to filling. By the use of the improved tool painters are enabled to attend quickly to the clearing out of cracks of plaster-covered walls, combining two operations necessary by the use of tools hitherto in use into one, saving thereby considerable time and labor.
Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. A crack-cutting tool comprising a shank, and two blades extending fromsaid shank and interconnected at both ends, said blades being spaced apart at their intermediate portions and having a fusiform opening between the same.
2. A crack-cutting tool comprising a shank, and two curved cutting-blades extending therefrom and directly interconnected at both ends at substantially the same angle, said blades forming between them an elongated fusiform opening.
In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.
LOUIS NEWMAN.
