Patented Dec. 24, 1940 f UNITED STATES PATENT OFFICE SCRAPER DEVICE Irving A. Pollack, New York, N. Y. Application September 23, 1939, Serial No. 296,171

2 4 Claims. (01. 30-136) This invention relates to improvements in scrapers and more specifically to a scraper for removing calcimine from Walls or other fiat coated surfaces. v

Heretofore, wall scrapers with which I am familiar, are incapable of scraping calcimine or paint from the right angular corners between a wall and a ceiling for the reason that the angular corner prevents the blade of the scraper from reaching thereinto. Thus, the present wall scraper cannot remove all the calcimine and paint from a wall, and after scraping the wall surface within the limits of the use of such scraper other methods must be resorted to to effect a complete removal of the calcimine from the corners. It is therefore, the main feature of this invention to provide-a scraper which is capable of scraping an entire wall or ceiling up to the corners thereof.

Another feature of the invention resides in a scraper of the kind having a receptacle body into which the particles of calcimine or paint may be caught during a scraping operation and which is designed to not interfere with the use of the scraperwhen scraping into corners.

Another feature of the invention is to provide a scraper of the kind above mentioned which includes a removable scraping blade which permits replacement of the scraping blade when the same becomes Worn.

A still further feature of the invention is the provision of a scraper having the advantages hereinbefore set forth which is simple and inexpensive of construction, and light in weight so as not to be unduly tiring to the arm of a user during use thereof.

Other features of the invention will become apparent as the following specification is read in conjunction with the accompanying drawing, in which:

Figure l is a perspective view of the scraper device.

Figure 2 is a top plan view.

Figure 3 is an enlarged vertical transverse sectional view through the scraper illustrating the same in use for scraping the top of a wall adjacent its juncture with a ceiling.

Figure 4 is a vertical longitudinal sectional view looking forwardly to the blade side of the scraper.

Figure 5 is a perspective view of the scraper blade per se.

Referring to the drawing by reference characters, the numeral Ill designates my improved scraper device in its entirety, and which includes .ing edge 22.

a box-like receptacle body l. The body II includes a bottom wall l2 which in this instance is illustrated as being constructed of wood, the same having a straight rear side, straight end surfaces and .an arcuate convex front surface l3. The sheet metal wall structure is attached to the four sides of the bottom wall l2 and includes a rear wall M which extends at right angle from the bottom wall l2, end walls |5-|5 which gradually increase in height from the rear wall M in a forwardly direction, anda forwardly bowed arcuate shaped front wall Hi. The front wall l6 has a slight outward flare as best illustrated in Figure 3. The sheet metal forming the walls l4, |5|5 and I6 may be formed from one sheet of material bent around the four sides of the bottom wall l2 and secured by nails or other like fastening elements H, which pass through the walls and into the bottom wall I2. If desired,

however, the metal wall structure may be made of two or more separate pieces of metal secured to the bottom wall l2 in the same manner as herein illustrated. The top edge of the front wall I6 is concavely curved on an are extending from one end to theother end, and which concavely curved edge is designated |8 for a purpose to be presently appreciated.

A handle |9 is secured to the bottom wall l2 by a screw 20, the said handle being attached to the bottom wall at a point midway between the ends of the bottom wall, and extends from the bottom wall in a rearward direction so as toprevent the fingers of the hand of a person grasping the handle I9 from being disposed too far forward of the device during use thereof.

Removably supported by the forwardly bowed front wall It is a scraper blade 2|. The blade 2| is constructed of relatively thin steel which is normally flat and which has an inwardly curved arcuate scraping edge 22, the lower edge 23 of the blade being substantially parallel to the scrap- The blade 2| is of a length to extend across the forwardly bowed front wall I6 when in a bowed position conforming to the curvature of the bowed front wall It. The blade 2| fits against the exterior of the front wall I6 and the scraping edge 22 extends beyond the plane of the concavely curved top edge |8 of the front wall It, the curvature of the blade 22 being substantially the same as the curvature of the top edge l8. Fitting against the outer side of the blade 2| for clamping the same in a fiexed position against the exterior of the front wall 5 is a clamping plate 24, which may be normally curved to thecurvature of the front wall It.

Bolts pass through alined openings in the clamping plate 24 and the front wall [6, and threaded to the free ends of the bolts 25 are clamping nuts 26. To facilitate the insertion of a blade 2|, the nuts 26 are loosened so that the clamping plate 24 may be moved outwardly away from the front wall I6, after which the blade 2| is flexed and is inserted in a flexed condition between the exterior of the front wall l6 and the inner side of the clamping plate 24, the bottom edge 23 of the blade abutting the shanks of the bolts 25 to properly position the scraping edge 22 relative to the top edge l8 of the front wall I6, after which the nuts 26 are tightened to securely clamp the blade in rigid flexed condition.

In use of the scraper device ID for the scraping of calcimine or paint from a wall such as designated W in Figure 3, the user grasps the handle l9 and positions the scraping edge 22 of the blade 2| against the wall. Any portion of the concaved edge 22 of the blade may be brought into scraping engagement with the fiat surface of the wall but when it is desired to scrape the wall surface at the corner between the wall W and the ceiling C, it is necessary that the operator turn the scraper device so that that portion of the scraping edge 22 adjacent the ends of the blade flatly contact the wall surface as clearly illustrated in Figure 3. With the scraper device positioned as shown in Figure 3, the operator may move the device horizontally with an end edge of the scraping edge 22 disposed in the corner A between the ceiling C and the wall W. During the scraping of the calcimine or paint from the wall surface, particles scraped from the surface will drop into the receptacle H, and as it becomes filled, the body may be emptied into a waste receptacle.

While I have described the scraper device Ii! as being especially adapted for scraping wall surfaces and the corners thereof, it will be understood that this scraper may be used in other instances where two angular walls meet, and I do not wish to limit myself to any particular use of the article. Also, I have illustrated in the drawing and described one specific construction of the scraper, but it is understood that various details in construction and design may be resorted to, if desired, without departing from the spirit of the invention.

Having thus described the invention, What I claim as new and desire to secure by Letters Patent of the United States, is:

l. A scraper device comprising a receptacle body having an outwardly bowed front wall, a handle extending from said body, a scraper blade fitting against the exterior of said front wall and conforming to the bowed shape thereof, the scraping edge of the scraper blade being arcuately curved inwardly from one end to its other end and projecting beyond the plane of the top edge of the front wall, and clamping means for securing said blade in position upon said front wall.

2. A scraper device constructed in accordance with claim 1, in which the clamping means includes a bowed clamping plate fitting against the scraper blade and the front wall, and fastening elements passing through the clamping plate and front wall.

3. A scraper device comprising a receptacle body having an outwardly bowed front wall, a scraped blade fitting against the exterior of the front wall and conforming to the longitudinal curvature thereof, said scraper blade having an inwardly curved scraping edge disposed beyond the plane of the top edge of said front wall, and fastening means for securing said scraper blade to said front wall.

4. A scraper device comprising a receptacle body having an outwardly bowed front Wall, the top edge of said front wall being curved inwardly from one end to the other, a scraper blade fitting against' the exterior of the front wall and conforming to the longitudinal curvature thereof, said scraper blade having an inwardly curved scraping edge extending from one end thereof to the other end and being disposed beyond the plane of the top curved edge of said front wall, fastening means for rigidly securing said scraper blade to said front Wall, and a handle extending from said receptacle body.
