Mass.,acorporation'of Massachusetts V pplication November 3, 1944,. Serial no; se ner i (01. 30-171) 10 Claims.
This invention relates generally to. scrapersfor hand scraping in any desired application such as for instance the scraping of wood, paint, varnish. etc.- Y
Objects of the invention include the provision of a scraper of the type described which is 1}: adapted to releasably hold a scraping blade and in which the blade is firmly held or selectively easily andquickly 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 iscontrolled by a hand manipulatedelement, the latter being,
I received substantially completely withinthe body of the handle so that there are no protruding parts whichmight interfere with the manipula tion of the scraper. r
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 44 of Fig. 2.
A preferred embodiment of the invention is illustrated in the drawing and as there shown comprises a handle l which may be wood or similar material, this handle being shaped in general to fit the operators hand and having a widened head portion l2 which is referred to hereinafter as the blade head. The blade head is provided at its forward end with an inclined surface I4, the surface I4 providing one jaw of the blade clamping device against which blade I6 is positioned and clamped as will be described. Inclined surface 14 merges into the top surface I6 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. Y 1
The bladehead isprovided with a slot Mextending from side't'o sidethereof and terminating along the line 20. This-slot extends to the inclined surface l4-and divides the same between the lateral edges of the blade head I2.
A movable blade holding member is located in the slot as clearly shown and this member ex- 26 located within the slot- Member 22 is clearly:
capable of sliding in the slot so as to bring the body 24 to andfrom the inclined surfacev I 4 so.v
as to clamp or release blade iii as clearly shown in Figs. 2 and-3.
In the bottomjsurface of the handle in the;
region of the blade head [2;there is provldeda bore 28 receiving a fastening elementdll 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 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 the fastener 30 in the manner shown in Fig. 3 so that the eccentric 33 rests upon a surface of the slot l8 and in the aperture 26 in blade holding member 22. The operatingelement 34 is provided with a finger grip 40, the latter being received substantially completely within the depression 36 so that there are no parts extending beyond the top surface of handle l0. It will also be seen that the bottom surface of handle [0 is likewise free and clear of any encumbrance or protuberance, 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 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 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 complete scraper. The scraper is of long life and '1 it is extremely simple to operate the blade hold- Jing means. In addition there is nothing extending beyond the surfaces of the scraper to interfere with the operation of the same so that the hands of the operator will not be interfered with I in any way.
Having thus described my invention and the advantages thereof, I do not wish to be limited 5 to the details herein disclosed, otherwise than as set forth'in the claims, but What I claim is:
1. In a' device of the class described, a handle, 1
a blade clamping surface associated with the 2. 'In a device of the class described, a handle,
7 a blade clamping surface associated with the handle, ;a movable blade clamping member for cooperation'with said surface to clamp 'a blade therebetween, an eccentric for drawing the blade clamping member against said. surface, and a centric, said elementgbeing located substantially wholly in the handle.
. 3. ,A scraper ,comprising a handlela movable blade clamp thereon, a cam operating theblade v: clamp, anda hand manipulated element controls. lingthe' cam, the element being located substantially wholly within the body of thehandle. .4. A'scraper comprising a handlea movable bladev clamp. thereon, "a movable finger piece located in thehandle, cam means associated with the finger piece to move the clamp, and means 7 securing the finger-piece to-the handle;
5. A scraper comprising a slotted handle,
blade clamping surface thereon, a movable blade hand manipulated element for operating said .ec-
clamp in the slot, a recess in a surface of the handle, a cam for engaging the blade clamp, a' finger piece in the recess, said cam being operable by the finger piece.
6. A scraper comprising aJslotted handle hav ing a recess in a surface thereof, the recess and slot intersecting, a movable blade clamp in the slot, a cam engaging the clamp for moving the latter, and a finger piecein the recess; said cam being movable by'the finger. piece.
. '1. A scraper as recited in'claim 6 wherein the recess is deep enough to contain substantially the entire finger piece. I r
V 8. A scraper comprising a. handle, a blade clampingsurface thereon, a slot intersecting the surface; a recess in another surface of the handle, the recess and slot intersecting, a blade clamp in the slot, a cam in the recess, means to operate the cam to draw the blade clamp to the blade clamping surface, said means being located substantiallypwholly in therecess.
9., 'Ascraperjcomprising a. handle having top andbottom surfaces, a-slotin. the handle, a
blade clamp in the slot, a recess in the top surface of the handle, a recess in the bottom surface of the handle said recesses intersecting theslot, a cam vfor operating ,the clamp, 2a finger-piece in one recess for operating the cam, a fastener in the other recess,.said fastener securing the cam and finger piece to the handle.
