United States Patent O 3,562,826 MULTIPURPOSE SCRAPING TOOL James P. Vaughn, 3403 Connelly Lane, Chattanooga, Tenn. 37412 Filed Nov. 29, 1968, Ser. No. 779,860 Int. Cl. B26b 11/00 U.S. Cl. 7-14.1 1 Claim ABSTRACT OF THE DISCLOSURE A multipurpose scraping tool having a magnetic device secured thereto for removably attaching said tool to any magnetizable surface. The tool is especially useful to a housepainter in preparing a wall preliminary to painting, said tool comprising a handle, hammering means at one end, a sharpened edge for scraping at the other end, nailpulling means located therebetween, and a magnetic device secured to the tool.

This invention relates to a multipurpose tool having a magnetic device secured to said tool for attaching said tool to any magnetizable surface where it is easily located and removed, and more particularly, this invention relates to a multipurpose scraping tool especially useful to a housepainter, combining novel features within its structure to permit use as a scraper, a glazing tool, a nail puller, putty knife, and a hammer.

A housepainter, or one performing similar tasks, ordinarily must carry a multitude of separate tools, each having one or two functions, in order to perform operations which are preliminary to the painting operation. Frequently, these tools are misplaced, or fall from the ladder to the lloor below, thereby resulting in damage to the tool, or injury to persons. The instant invention rectilies these difficulties by providing a single tool having a multitude of uses, such as a paint scraper, hammer, nail puller, glazing tool, putty knife, all of which are incorporated 'within the tool structure, and including means for magnetically attaching the tool to any magnetizable surface nearby, such as a steel ladder, or scaffold, where it is retained for future use.

It is, therefore, an object of this invention to provide a multipurpose scraping tool which is efficient in design, simple to use, and economical to manufacture.

Another object of this invention is to provide a multipurpose scraping tool having a handle, a hammerhead at one end of said tool, a sharpened edge useful for scraping, glazing, or puttying, at the other end, nailpulling means located therebetween, and a magnetic device secured to the tool for attaching the tool to any nearby magnetizable surface,

Another object of the invention is to provide a multipurpose scraping tool having a handle with a built-in magnetic device.

Other objects and advantages of this invention will be made readily apparent from the disclosure in the attached specication, and from the accompanying drawing, wherein:

FIG. 1 is an elevational rear view of a specic embodiment of the multipurpose scraping tool comprising the subject matter of the instant invention.

FIG. 2 is a sectional view taken substantially on line 2-2 of FIG. l, showing the various components of the magnetic device.

FIG. 3 is a partial elevational front View of a specific embodiment of the instant invention showing the projected portions of the magnetic device attached to the scraping tool.

Referring now to the drawing, wherein like numerals indicate like elements throughout the several views, a

Ffice specific embodiment is generally indicated by the numeral 10. As shown in FIG. 2, the multipurpose tool, or paint scraper `10, includes blade member 12, preferably of onepiece steel construction, said blade member 12 having an upper portion 14, an intermediate portion 16, and a lower portion 1S, all of which are integrally connected so as to form the basic tool structure.

Upper blade portion 14 is a solid cylinder of considerable weight relative to the remainder of blade 12, having flattened front and

rear surfaces

15, 17 which are parallel to the flattened intermediate portion 16,

Edges

19, 21, chamfered at approximately 45 are provided on

cylindrical surfaces

15, 17, respectively. As is readily apparent, either surface 15 or surface 17 may be used as a hammer for driving nails, tacks, etc., into a wall.

Intermediate blade portion 16 extends forwardly from said upper portion 14 and is relatively flat, having a substantially rectangular cross-section. A pair of

holes

22, 24 spaced apart and located on the longitudinal axis of intermediate portion 16 provide attaching means for handle 30. Handle 30 comprises front and

rear sections

32, 34, each section having a pair of

holes

36, 38 spaced apart and located on the longitudinal axis of

said sections

32, 34, which are aligned with

holes

22, 24 so as to permit the fastening of

sections

32, 34 to intermediate blade portion 16 with rivets 39. In lieu of rivets 39 other mechanical fasteners, such as pins, screws, or chemical adhesives, such as epoxy resins, may be substituted therefor.

Sections

32, 34 may be made of non-metallic materials, such as plastics, wood, rubber, or non-magnetizable metals, such as aluminum, glass, or magnetizable materials which are magnetically insulated from the magnetic device placed nearby.

Sections

32, 34 have flat parallel external and internal surfaces `40, 42, 44, 46, and said

external surfaces

40, 44 may be marked, or scored, in any fashion desired to provide additional gripping surface.

Sections

32, 34 have approximately uniform thicknesses throughout their length having sides 48 which taper downwardly from the wider upper end 50 to the narrower lower end 52. Edge 54 of

handle sections

32, 34 is contoured in a concave manner so as to partially envelop the cylindrical upper blade portion 14, or hammer, to which edge 54 is adjacently placed.

In this manner a reduced-width handle 30 which is easy to grip, covers the underlying intermediate blade portion 16 `where it is secured thereto.

A recess, or shaped cavity 6l) is provided in either one of

said sections

32 or 34, as shown in 32 in the drawing, said cavity [being approximately centrally disposed and extending forwardly from internal surface 42 to form a rst zone 62 of rectangular dimensions and parallel with surface 42, a second zone 64 also of rectangular shape and extending from zone 62 forwardly, but of reduced area, and a third zone 66 partially extending from zone 64 and communicating with external surface 4t) by a pair of rectangular conduits to form

apertures

68, 70 on surface 40. Cavity 60 is dimensionally proportioned so as to receive and support the magnetic device 72 which is placed therein.

The magnetic device 72 includes a permanent magnet 74 and a magnetically adhering pole piece 76, said permanent -magnet 74 being a bar magnet having a substantially flattened rectangular shape. Permanent magnet 74 may be made of any material possessing sufficient magnetic strength to support scraping tool 10 when said tool is placed against an upstanding magnetizable surface. Pole piece 76 is of generally U-shaped dimensions, preferably of steel construction, and has a flattened middle portion 78 with perpendicular flange members or legs 80 projecting forwardly from middle portion 78 at its upper and lower ends. Flange members 80 have a cross-sectional rectangular shape of approximately the same size as

aperture

68, 70. Flange members 80 are of sufficient length to project beyond surface 40 after permanent magnet 74 and pole piece 76 are placed within second zone 72 of cavity 60.

Middle portion 78 includes a front and

rear surface

81, 82 which are disposed parallel to intermediate blade portion 16 and is separated therefrom by a magnetically insulating member 84. Insulating member 84, which may be of a fibrous nature, is also of generally rectangular dimensions, is placed at against surface S2 and lls first zone 62 of cavity 60. In this manner, the pole piece 76 and permanent magnet 74 are insulated from intermediate blade portion 16, thereby preventing the magnetization of said blade portion.

Lower blade portion 18 includes a triangular aperture 92 being approximately centrally located along the longitudinal axis of portion 18 wherein the apex of aperture 92 points downwardly. In order to provide theleverage for removing nails, lower blade portion 18 is bent at a position above aperture 92 and said portion shown at position 22 forms an angle of approximately 20 with the longitudinal axis, thereby lextending in a direction away lfrom the surface upon which the tool is placed.

In using the above-described scraping tool as a hammer, the operator grasps handle 30 and proceeds to apply the upper blade portion 14 against the nail, or tack, by means of placing

surfaces

15 or 17 directly in contact with said nail. By reversing the position of the tool in the users hand, the user may then remove nails, or tacks, by inserting said nails, or tacks, through aperture 92 and by applying the proper leverage, remove' the nail, or tack, from the surface.

In a similar fashion the operator may use tool 10 to scrape paint, varnish, or any other coated surface capable of being removed by the sharpened edge 90. Putty may also be applied to cracks, holes, by the lower yblade portion 18.

Upon completion of any of the scraping, glazing, hammering, nail pulling, or puttying operations, the user can easily temporarily attach multipurpose tool 10 to any nearby magnetizable surface merely by placing magnetic device 72 of tool 10 against said surface whereby, by virtue of the magnetic forces induced within said surface the tool is rmly held in place. The magnetizable surface requires no added holders or additional magnetic devices 'to be eective. Once tool 10 is secured it remains out of the users way, but within easy reach for further use. This is especially important when working on elevated structures, such as in new building construction, where the elimination4 of falling objects is especially noteworthy.

Thus, from the foregoing, it will be seen that the instant invention provides a multipurpose tool which is simple in design and manufacture having a magnetic device attached thereto for attachment and subsequent detachment from any magnetizable surface.

While a preferred embodiment of the multipurpose scraping tool has been described in the foregoing description, it should be understood that this invention is not limited in its scope to the embodiment described, and variations in the form of the invention are contemplated thereby.
