Application filed May 14, 1923. Serial No. 638,764.

ToaZZ whom it may concern:

Be it known that I, JOSEPH O. CHARPEN- TIER, a citizen of the United States, residing at Concord, in the county of Merrimack and State of New Hampshire, have invented new and useful Improvements'in Scrapers, of which the following is a. specification.

The general object of this invention is to provide an implement adapted to scrape the ceiling of a room to remove dust and dirt therefrom, and to prepare the ceiling for subsequent treatment, the implement having means for catching and. accumulating the matter removed from the ceiling, to prevent such matter from being scattered on the floor.

Particular objects of the invention will appear from the following specification, and the novel features will be pointed out inthe appended claims.

Of the accompanying drawings forming a part of this specification,

Figure l is a side elevation of a scraper embodying the invention.

Figure 2 is a section on line 2-2 of Figure 1.

Figure 3 is an enlargement of a portion of Figure 2.

Figure l is a perspective view of the dust pan shown by Figures 1 and 2.

Figure 5' is a perspective view of a portion of the handle.

Figure 6 is a perspective view of the scraper-holding plate hereinafter described.

Figure 7 is a perspective view of the scraper.

Figure 8 is a diagrammatic view hereinafter described.

In the drawings, 12 represents an elongated. handle, preferably a wooden rod about six feet long, although the length may be varied. One end of the handle is provided with a metal ferrule 1.3, this end and the ferrule being provided with a transverse slot 14, best shown by Figure 5.

15 represents a scraper-holding plate, preferably of sheet metal, provided with parallel ears 16, overhanging a portion of the body of the plate, and forming therewith channels adapted to receive opposite ends of a scraper 17. The scraper is an oblong metal plate having scraping edges 18, which constitute the opposite edges of the plate and are adapted to be used interchangeably, as hereinafter described. The sides of the plate may be beveled to reduce the thickness of the edges 18, or said edges maybe of the full thickness of the plate, and kept sharp by grinding off their surfaces from time to time, to keep the edges 18 at right angles with the sides of the plate.

The scraper is detacha-bly secured to the holding plate 15 by means of a tongue 19, formed on or attached to a spring shank 20, the resilience of which causes it to press the tongue 19 into coinciding slots 21 and 22, formed respectively in the scraper and the holding plate 15.

The rear end portions of the holding plate 15 and of the spring shank 20 are inserted in the handle slot 14:, and secured therein by one or more rivets 23, as best shown by Figure 3.

24 represents a dust pan, to the back of which is secured a cylindrical tubular socket 255, by a shank 26, which is soldered, or otherwise secured to the back of the pan. The socket 25 has a close frictional fit on the handle 12, and is adapted both to turn and move endwise on the handle, the frictional fit holding the socket in any position to whichit ma be moved on the handle.

The arrangement is such that when the scraper is applied to a ceiling by an operator standing on the floor and manipulating the handle 12, the'dust pan is located under the scraper and in position to catch matter removed from the ceiling by the scraper. Owing to the fact that the socket is adapted to turn on the handle, the pan bottom may stand substantially parallel with the scraper, or may be inclined relative to the scraper, as shown diagrammatically by Figure 8, thus enabling one end of the scraper to enter the corner between a ceiling and a vertical wall 28, the pan bottom being inclined relative to the scraper and one end of said bottom being imder the end of the scraper which is adjacent to the wall 28.

Owing to the fact that the socket is adapted to move endwise on the handle, the pan bottom may be adjusted so that its forward edge is directly under the forward edge of the scraper and adapted to catch matter falling therefrom, when the handle is held at different inclinations, the pan being adjusted outward when the handle is held at Thediesoribed means for detachablycom neoting the soraper With the handleen-ablesa two-edged scrapert0b8v employed, the edges of. which are adapted to be used interchangeably, so that When one edge be.- comes dull, the scraper may be reversed and the opposite edge utilized I claim:
