Application November 3,1944, Serial No. 561,701

Claims. (CI. 30—171)

This invention relates generally to scrapers for hand scraping in any desired application such as for instance the scraping of wood, paint, varnish, etc.

Objects of the invention include the provision of a scraper of the type described which is adapted to releasably hold a scraping blade and in which the blade is firmly held or selectively easily and quickly released; the provision of a scraper as aforesaid comprising a handle including blade holding means thereon and means for clamping or loosening said blade holding means with a minimum of time and effort required and in which the blade holding means is controlled by a hand manipulated element, the latter being received substantially completely within the body of the handle so that there are no protruding parts which might interfere with the manipulation of the scraper.

Further objects of the invention include the provision of a scraper comprising a handle having a blade clamping face thereon, together with a movable member for clamping the blade against the face and releasing the same, in combination with an easily operable hand manipulated element which may be turned a very small amount to release or clamp the blade holding member to firmly hold or quickly release the blade.

Other objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanying drawing, in which

Fig. 1 is a top plan view of a scraper embodying the invention;

Fig. 2 is a view of the scraper of Fig. 1 in side elevation;

Fig. 3 is a section through the blade clamping device; and

Fig. 4 is a bottom plan view of the blade clamping device taken substantially along the line 4—4 of Fig. 2.

A preferred embodiment of the invention is illustrated in the drawing and as there shown comprises a handle 10 which may be wood or similar material, this handle being shaped in general to fit the operator’s hand and having a widened head portion 12 which is referred to hereinafter as the blade head. The blade head is provided at its forward end with an inclined surface 14, the surface 14 providing one jaw of the blade clamping device against which blade 16 is positioned and clamped as will be described. Inclined surface 14 merges into the top surface 16 of the handle, the latter providing a rest for the hand of the operator for a downward pressure on the blade head during the scraping action.

The blade head is provided with a slot 18 extending from side to side thereof and terminat5 ing along the line 20. This slot extends to the: inclined surface 14 and divides the same between the lateral edges of the blade head 12.

A movable blade holding member 22 is located in the slot as clearly shown and this member ex10 tends forwardly, protruding out of the slot and extending downwardly terminating in a jaw member 24 parallel to the inclined surface 14. Member 22 is provided with a circular opening 26 located within the slot. Member 22 is clearly· 15 capable of sliding in the slot so as to bring the body 24 to and from the inclined surface 14 so as to clamp or release blade 16 as clearly shown in Figs. 2 and 3.

In the bottom/surface of the handle in the·.

region of the blade head 12 there is provided a bore 28 receiving a fastening element 30 fitting the bore to prevent sidewise movement therein. The fastening element 30 may be provided with a pin or the like 32 extending upwardly to receive 25 and secure an operating element 34, the latter being received in a circular depression in the top of the handle as at 36. Operating member 34 is provided with a circular eccentric 38 and the pin 32 may, secure the operating member 34 to 30 the fastener 30 in the manner shown in Fig. 3 so that the eccentric 38 rests upon a surface of the slot 18 and in the aperture 26 in blade holding member 22. The operating element 34 is provided with a finger grip 40, the latter being received 35 substantially completely within the depression 36 so that there are no parts extending beyond the top surface of handle 10. It will also be seen that the bottom surface of handle 10 is likewise free and clear of any encumbrance or protuber40 ance, and that essentially there are no unexposed openings in either surface.

• It will be seen that the eccentric 38 will quickly and tightly force blade clamping member 22 to the right in the figures upon a very slight turn 45 of the operating element 34 in a clockwise direction; and on the other hand a very slight turn of the operating member in the opposite direction will serve to release blade clamping member 22 so that the blade may be removed and reversed 50 or a new blade substituted.

It will be seen that this invention provides a simple and easily manufactured scraper having a quick release and clamp for the blade, there being only three metal parts necessary for the com55 plete scraper. The scraper is of long life and
