' SCRAPER.

SPECIFICATION forming part of Letters Patent N0.'629,487, dated July 25, 1899. Application filed May 18, 1899. Serial No. 717,319. (No model.)

To all whom it may concern.-

Be it known that I, JOSEPH T. BOUFFORD,

of Linwood, in the county of WVoreester and State of Massachusetts, have invented a new and useful Improvement in Scrapers; and I hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification.

This invention has reference to an improvement in a tool designed for use in smoothing and scraping the surfaces of floors and other woodwork; and it consists in the peculiar and novel construction of the scraper, as will be more fully set forth hereinafter.

When woodwork, and particularly hard wood, has been brought to the desired surface and is designed to be varnished, waxed, or polished, the marks of the plane are removed by a steel plate, usually held by the hands of the user.

In finishing the surfaces of floors and other woodwork the scraping with the usual steel plate is very fatiguing.

To facilitate the use of the scraper is the object of this invention.

Figure 1 is a side view of my improved scraper. Fig. 2 is a top View, and Fig. 3 an end view, of the same. Fig. 4 is a front view of the scraper-plate, and Fig. 5 is a sectional View of the scraper.

In the drawings, A indicates a preferably rectangular bar having the handle a at one end and the bevel end a at the opposite end.

Near the lower edge of the beveled end a the pins 0. are secured in the bar A so as to project slightly above the surface and enter the slot b to prevent the side movement of the plate B.

The plate B is a thin steel plate having at one end the straight scraping edge b and at the other end the curved edge 12 also has the slot 12 having at its opposite ends a width equal to the shank of the screw 12 and in the center an enlarged opening, through which the head of the screw b may bepassed. The plate 0, which is slightly tapering and of wedge-shaped section, as is shown in Figs. 1 and 5, is provided with the central slot 0, the lower end of which is enlarged,lso that the head of the screw b can readily pass through, the other portion of the slot 0 being of a width sufficient for the passage of the shank of the screw 1). The upper end of the The plate convex form, adapted to fit the ball of the hand.

In assembling the parts the screw 12 is secured in the beveled end of the bar A. The plate B is placed over the head of the screw b and adjusted to bring the contracted portion of the slot 5 to bear on the shank of the screw, the pins 01. entering the lower contracted portion of the slot 19 plate 0 is placed over the head of the screw 19 and pushed down to wedge the same between the head of the screw 1) and the plate B, and by so doing holds it firmly against the The holding beveled end a of the bar A, the screw 12 and the pins a holding the plate B against side movement.

In use the handle a of the bar A is grasped the combination wit-h a bar having at one end the handle a and at the other end the beveled end a, of a screw b the slotted, spring-steel plate B, the curved edge I) and the'straight edge I) at the opposite ends of the plate, the holding-plate O of wedge-shaped section and the handhold c at one end of the plate, as described.

2. In a scraping-tool, the combination with the bar A having the handle a at one end and the beveled end a at the opposite end, of the slotted, spring-steel plate B, the pins a on the beveled end of the bar A, the holding-plate O, the handhold c on the same and the screw 6 whereby the spring of the steel scraper is increased, as described.

In witness whereof I have hereunto set my hand.

JOSEPH BOUFFORD.
