2 Claims.

This invention relates to scrapers and, while adapteol for various purposes, is particularly intended for use as a -scraper to remove ice and sleet from the windshields and windows of automobiles, trucks, etc. in the Winter time.

Varius forms of scrapers have heretofore been suggested for this purpose, some of which employ special blade-s, While others are adapted for the use therewithin of ordinary razor blades. These blades are usually of very hard metal and there is the ever present tendency in their use to scratch the glass of windshields and windows. Moreover, they are found in practice to quickly rust and fail to function properly in use.

The object of the present invention i-s to provide a, highly eflicient scraper of the character described, so constructed that lt will be streng and durable, may be reaolily grasped and held firmly in the hand of the user, and so constituted that it cannot possibly scratch glass o1 any other material on which it is used.

The scraper of this inventi0n is provided With a blade of an organic plastic, preferably Luchse, one longitudinal edge of which is beveled to a relatively keen scraping edge. The opposite longitudinal edge of the blade is set into a metallic channel section cut away for the greater portion of its length, so as to allow the blade to properly conform to the surface to be scraped and adjacent the opposite ends of the channel section are secured the opposite ends of a wire handle bent to form a relatively broad convenient grip. The ends of the wire handle are fiattened t0 1ie flat against one face of the channel section and rivets are passed through these flattened ends and through the channel section and the base of the blade to retain the parts in assembled relation. The handle is offset so that the portion thereof adapted to be gripped by the user lies in the same plane as the blade.

Features of the invention, Other than those adverted to, Will be apparent from the hereinafter detailed description and appended claims, when read in conjunction with the accompanying drawing.

The accompanying drawing illustrates one practical embodiment of the inventisn, laut the construction therein shown is to be understood as illustrative, only, and not as defining the limits of the invention.

Figure 1 is a, face view of the scraper embodying the present invention.

Figure 2 is an edge view of said scraper.

Figure 3 is a plane section 0h the line 33 of Figure 1.

In the drawings, l designates a blade which in practice is made relatively long and is beveled along its forward edge, as shown at 2 to provide a keen scraping edge 3. This blade is made of an organic plastic, preferably Lucite, which is sufilciently hard to efiectually remove ice from windshields, etc. without scratching the glass thereof. The blade is made sufiiciently thick to give it the necessary strength, laut not so thick that it will be too rigid. We have found in practice that a blade to in thickness will operate with high efliciency.

The base of the blade is seated within a metallic channel section 4, the major portion o1 which is cut away intermediate the ends of the section, as indicated at 5, to permit some slight flexibility of the blade, so that its scraping edge may conform With the surface operated upon.

The handle 6 is made of relatively rigid wire bent into substantially U-shape with the sides thereof drawn in to better conform to the hand of the user. The ends of the wire handle are fiattened, as indicated at I, and are adapted to overlie one face of the channel section and rivets 01 bolts 8 passed through the flattened handle ends, through the channel section, and through the blade to permanently maintain the parts in assembled relation. The handle is offset, as shown at 9, so that the gripping portion of the handle lies in the same plane as the scraper l.

The device of this invention is strong and rugged so that considerable force can be applied to the scraper blade, when occasion so requires, so as to insure a thorough cleaning of the glass on which it is used. The blade Will retain its sharp edge for prolonged periods, but, in the event that it becomes dulled, it may be readily sharpened again by rubbing the bevel 2 thereof 011 sandpaper 01 by taking a light cut from the blade through the use of a plane o1 similar tool. The cut-cut 5 permits the blade to adapt itself to slight irregularities in the surface to be scraped for it permits some fiexibility of the blade in a longitudinal direction. At the same tirne the tapered end portions of the channel section which are not cut away sufficiently support the blade to permit of the application of such pressure thereto as may be necessary to remove obstructions, ice, etc.

The foregoing detailed description sets forth the invention in its preferred practical form, but the invention is to be understood as fully commensurate with the appended claims.

Having thus fully described the invention,

what We claim as new and desire to secure by Letters Patent is:

l. A scraper of the character described having a straight blade of relatively rigid organic plastic provided along its front longitudinal edge With a bevel to form a sharp scraping edge and perforated near its rear longitudinal edge a.nd near its opposite ends, a rigid one pie ee channel cf U-shaped crssS Secti0ri el'nbracing i:he real longitudinal portion of the blade and having in its fianges at the opposite sides of the blade perfora tions alined With those of the blade, a rigid one piece looped wire handle with its integral f1"ee ends fiattened and perforated to provide broad and fiat ears seated againsi; the otei surfa'ce 'of one of seid flanges with their perforationg alined with those of the channel an'd blade, ai1d. iivet's passing through the alined perforations of the handle, channel and blade for permanently secur-ing the handle, blade and ehannel in as sembled relation.

2. A sc;raper of the character desrib'ed h.'a'ving a stra;ight Blade f relativ'ely rigid orani plastic .pr ovided along ics front longitudinal edge with a bevel to form a shafp scraping' ed'ge ar1d peri orated near its rear longitudinal ed'ge 9Jnd near its oppoeite ends, a 1ig-id one pi'ece cha'nnel 01 -shaped cross s'ectioh einbracing the rear longitudinal portion,of the blade and having in its fianges ab the opposite sides of the blade perforations alined with those 0f the blade, a rigid one-piece looped wire handle with its integral free ends flattened and perforated to provide broad and fiai; ears seated against the outer surface of one of said flanges with their perforations alined with those of the channel and blade, and rivets passi'ng through the ali'ne'd 'perforations of the handle, channel and blade for permanently securing the handle, blade and channel in assembled relation, said looped wire handle being oifset back of the channel so that the major portion cf the handle lies in the same plane as ehe bladiz.
