The
plate B is a thin steel plate having at one end the straight
scraping edge b1 and at the other end the curved edge
b2. The plate also has the slot b3, having at
its opposite ends a width equal to the shank of the screw b4
and in the center of an enlarged opening, through which the
head of the screw b4 may be passed. The plate C, which
is slightly tapering and of wedge-shaped section, as is shown
in Figs. 1 and 5, is provided with the central slot c1,
the lower end of which is enlarged, so that the head of the
screw b4 can readily pass through, the other portion
of the slot c1 being of the width sufficient for the
passage of the shank of the screw b4. The upper end of
the plate B is provided with the handhold c2, of convex
form, adapted to fit the ball of the hand.
In the assembling the parts the screw b4 is secured in
the beveled end of the bar A. The plate B is placed over the
head of the screw b4 and adjusted to bring the contracted
portion of the slot b3 to bear on the shank of the screw,
the pins a2 entering the lower contracted portion of
the slot b3. The holding plate C is placed over the head
of the screw b4 and pushed down to wedge the same between
the head of the screw b4 and the plate B, and by so doing
holds it firmly against the beveled end a1 of the bar A, the
screw b4 and the pins a2 holding the plate B against
the side movement.
In case the handle a of the bar A is grasped by one hand
and ball of the other hand is pressed on the handhold c2.
Usually the curved edge b2 is used first to rough-scrape,
and then the plate B is reversed, so as to finish with the straight
edge b1. When used on floors, the operative by slightly
stooping can draw the scraper over the floor and readily scrape
the same. The spring of the steel plate B materially facilitates
the operation.
Having thus described my invention, I claim as new and desire
to secure by Letters Patent—
- In a tool of the nature herein described, the combination
with a bar having at one end the handle a and
at the other end the beveled end a1, of a screw b4,
the slotted steel-spring plate B, the curved edge
b2 and the straight edge b1 at the opposite
ends of the plate, the holding-plate C of wedge-shaped
section and the handhold c2 at one end of the
plate, as described.
- In a scraping-tool, the combination with the bar
A having the handle a at one end and the beveled end
a1 at the opposite end, of the slotted, spring-steel
plate B, the pins a2 on the beveled end of
the bar A, the holding-plate C, the handhold c2
on the same screw b4; whereby the spring of
the steel scraper is increased, as described.

witness whereof I have hereunto set my hand.
