SCRAPER Filed Feb. l0, 1933 Patented Aug. I4, 1934 STATES PATENr [OFFICE 14' Claims.

rIhis invention relates to blade holding tools, especially of the type adapted to be used as Scrapers.

One object of this invention is to provide an improved device of the character described including a movable blade carryingclampingelement whereby the cutting edge of the blade can be projected or retracted relative to an edge of a body member having, a handle, whereby increased safety isaffordedwhen the device is not in use. f

Another object of this invention is to provide a device of the nature setforth having improved abutment means for supporting the clamping member inthe use of the tool; and further to provide such means as will reliably maintain the clamping member retracted;

Another object of this,l invention is to construct a tool ofA the class described having a .20 blade and an associated scraping means that can be used interchangeably with the blade; and preferably wherein the edges of the blade and as. sociated scraping means can be protectively covered when theA tool Vis not used. l

A further object of the invention is to furnish a deviceof the type mentioned having few and simple parts, and'which is reliable and convenient in use, inexpensive and compact in construction, durable, and efficient. A v 4 Other objects and advantages of the invention will vbecome apparent as the speciiicationproceeds. Y

With the aforesaid objects in view, the invention consists in the novel combinations and arrangements of parts hereinafter described in their preferred embodiments, pointed out in the subjoined claims, and illustrated on the annexed drawing, wherein like parts are designated by the same reference characters throughout the 40 several views.
