4 Claims. (Cl

An object of the invention is to provide a new scraper construction wherein a storage space for spare blades is formed in the handle thereof.

Another object of the invention is to provide a scraper construction in which the handle has a sliding cover over a chamber therein, which chamber serves as a receptacle for spare blades.

Another object of the invention is to provide a scraper construction wherein it is possible to rotate or change position of the blade element and its -guard Yto a limited degree without separating the blade element and its guard from the handle.

A further object of the invention is to provide an improved keeper or Vguard member to be associated with a blade and with a handle.`

In carrying out the foregoing and other objects of the invention, a frame for a scraper construction is so formed that the `handle part of the frame has a channel or chamber formed therein. Associated vvith` said handle part is` a cover member attached thereto for sliding movement so that the chamber serves asa receptacle for spare blad-es. The sliding movement of the cover relative to the handle is accomplished by the provision of flanges extendingoutwardly from opposite edges of the handle to fit in channels formed in the cover by rolling over the edges thereof. thatthe cover can befdisengaged from the handle whenso desired and in addition locking means are provided for `resisting disengagement of the cover member from the handle. I

The blade holding end of the frame is provided with a pair of spaced openings disposed l adjacent the respective side edges of the frame, anda third opening disposed along one edge of the frame and spaced from one of the `pair of openings a distance distance between the first `mentioned openings.

The flanges are of limited length so and connected to the flat part by a bend in the metal. This guard is provided with three aper+y tures and the walls of these apertures are extended beyond one surface of the guard in the form of burrs. The central aperturejhas the wall of the burr threaded for the reception of` a thumb screw. The two end burrs are positioned, apart a distance permitting them` `to register with the first mentioned two openings inY the frame and also to permit one of. them to register with one of vsuch openings ,and Withthethird opening. The central burr is so located as to register with the arcuate slot in the frame. Such registry of the parts permits the guard and a blade positioned between the guard and the frame to be rotated `to a limited extent with one of the openings in the framev as `a pivotal point without removing the thumb screw which holds the parts in assembly. 1

Other features, objects, and advantages of the invention will be apparent by referring to the following detailed description of the accompanying drawing wherein l Fig. 1 is a plan view ofV a device embodying the invention;

Fig. 2 is an enlargedsection `taken substantially on the line 2-2 of Fig. 1;

Fig. 3 is an enlarged section taken substantially onthe line 3-.3,of Fig. y1; Fig.` 4 is `a section taken substantially on the line 4,-4 of Fig. `1;

Fig. 5 is a plan view of the guard member used in this construction; Y

Fig. 6 is a plan view of a blade used therein; Fig. '7 is a fragmentary plan view of the blade holding end of the handle, and y Fig. 8 is a plan view of the cover member associated with the handle. i A' Referring now to the drawing, I0 indicates generally the `frame of the device made up in part of a handle or chamber portion II and a approximately equal to the Also, this end part of the frame is provided with an arcuate shaped opening extending from midway between the first two openingsto midway betvveenone of the` rst two openings and the third opening. This'arcuate shaped opening has a connecting channel extending midway therefrom to one of the first mentioned openings.

`The guard member utilized with the frame is made up` of `a substantially flat metallic plate having a rib formed inV one edge portion thereof head or blade Yattachment portion I2. The handle part II is formed inthe operation wherein this member IIJ is stamped from sheet metal in such fashion that the flat back partthereof has side Walls I4 and a curved-in wall I5. The side walls I 4 have short flanges I' extending substantially from the end of the curved wall I5 to a point II at which the walls are arranged in converging relation. v

Associated with the handle is a cover or lead member indicated generally at 20 stamped or formed from sheet metal in such fashion as to have a substantially flat. part '/llrwith` the end thereof curved as at 22 tol correspond to. the

aperture curvature of the wall I5. The edges of the flat part 2| are rolled as indicated at 22' to form channels 23 of such width as to be capable of frictionally receiving the flanges I5. The end of the plate 20 opposite the curved pari; 22 has a tongue 24 extending therefrom at an angle of substantially 45. The curved end 22 of the ymember 20 has a narrow flange 25 extending therefrom and also has a button or indentation 26 formed therein.

Due to this arrangement of the handle and the cover, it is possible to engage the cover with the handle II by registering the channels 23.

with the flanges I6 at the ends of these flanges nearest the end wall I5. The cover member may then be moved in sliding fashion to partially close the chamber formed b-y the walls I4 and I5. When the sliding movement has been completed the edge of the end wall I5 is positioned between the flange 25 and the button or indentation .26. At the same time, the finger 24 extends into the chamber of the handle to a limited extent serving to retain spare blades in the handle chamber.

Due to the provision of the ange 25 and the button 26 V undesired sliding movement of the cover 20 is prevented but such sliding movement as to permit accessto blades in the chamber can be .accomplished by applying `pressure to the tongue 24, which pressure is of a degree only sucient to spring the cover member an amount toV permit the button 26 to ride over the edge of the end wall I5.

The blade attachment end or headv I2 of the frame has two

openings

30 and 3| therein which openings are-in alignment crosswise of the head. The opening 30 is circular in shape while the opening 3| has a part thereof rounded and leads into anv opening 32 extendingV into an arcuate Y shapedopening 34. This opening- 34 extends from va point midway between the

openings

30 and 3| to a point midway betweenthe opening 3| and another opening 35 spaced from k the opening 3| a distance equal to that between the openings-30 and-3|. The

openings

30 and 35 are disposed substantially at 90 vtov eachother.

The guard memberis"` stamped from, suitable sheet metal and comprises a plate 40,- one edge of. which has a longitudinal rib 4| joined tothe plate 40 by a bent portion 42. The plate 40 is provided with three

apertures

44, 45, and 4 6, respectively, the walls of which apertures are extended, by burrs formed in the metal, a slight distance beyond one surface of the plate 40. The

apertures

44 and 45 are spaced apart a distance sufficient to permit them tolregister. either with the apertures 3|) and 3|, of the part- I2 ofthe handle or with theapertures 3| and 35 of ,this

part.` The aperture Y46has the wall thereof inu cludingA its burr threaded to receive a thumb screw 53 which4 passes through the arcuate shapedopening34 in part I2 into engagement with the threads inthe wall of aperture 46.

The blade' .50 is constructed along conventional :i:

safety razordesign havingl two cuttingYedges-5I and` 52 andhaving, in the formV shown, three apertures54, 55 `and 5t.Y The apertures 54 and 56 areflocated to' receivethe burrs of the. aper-l and 45. of the guardmember while the tures 44 55 receives a threaded burrof aperture .'Ifhepartscan be .assembled in the manner shown in Figs.. l and 2 wherein -it will be seen that in one position of'these parts, one cutting edge of the blade is guarded by the rib 4| of the guard member. It should be noted that the row of openings in the guard member is positioned closer to the blank or free edge of the guard member than to the ribbed edge thereof. When it is desired to have an edge of the blade available for scraping purposes and to have this edge in substantial parallelism tothe line of the

openings

30, 3|, the thumb screw 53 can be turned to loosen the assembly of parts suiciently for the burrs of

apertures

44 and 45 to clear the under surface of the head I2; still retaining the parts in assembly. When this condition prevails, the guard and blade can be rotated through 180 until the burrs of the

apertures

44 and 45 are in reversed position relative to the

openings

30 and 3| of the head. When these burrs and openings a-re properly in register, the blade can be tightened by tightening thumb screw 53. Since the rib 4| extends slightly beyond the top surface of the blade, tightening of the thumb screw 30 causes the rib to' contact the under surface of head I2 and causes the guard to spring to a slight degree, thereby assuring that the blade will be tightly held against the head. Since the free edge of the guard is located some distance from the cutting edge of the blade, it will lie rearwardly of the end edge of head I2 so thatV the blade is permitted to'spring. more readily than if the free edge of the guard were in alignment with the end edge of the head I2.

Again assuming the parts are in the Fig. 1 position, the unguarded cutting edge of the blade can be moved into cutting position in which its edge is substantially parallel to a side edge of the head I2. To accomplish this movement, the thumb screw 53 is again turned to loosen the assembly until the burr of aperture 44 is clear of the lower surface of .head I2. With the burr of aperture 45 remaining in the opening 3|, the guard and bladecan be swung through an angle of during which movement the burr of aperture 46 remains in the arcuate opening 34; When the 90? turn has been completed, the burr of aperture 44 is brought into alignment withthe opening 35,;in the head. andthe. parts then can be tightened by turning the Vthumb screw. It should be noted also that other positions of the guard and blade canbeobtained by removing the thumbV screw from the ,assembly and. registering one or. more of the burrs of the guard with the desiredopenings in the head.

From the foregoing, it` will be seen that the present invention provides a new and improved scraper device combining features which increase the utility. thereof. I'he ,provision of the lockablecover for thechamber in the handle makes possible the storing. of spare blades in the handle. The arrangement of the openings in the head of the frame Amakes possible rapid adjustment of the unguarded edge of the blade to any desired position. It is to be understood that -,the invention is `capable of modiiications other than those illustrated herein; in View of which any limitations imposed thereupon are to be only those- Set forthin the following claims.
