Application :filed October 3, 1927. Serial No. 223,560.

This invention relates to a scraper .of the type commonly used in scraping glass to remove paint, varnish or other material which' may be deposited thereon. It is a A primary object and purpose of the present invention to construct a scraper of the type noted in a simple and novel mannerwhereby bolts, screws or the like for fastening the parts together are eliminated and the scraper member, which consists of a blade similar to a safety razor blade, may be clamped in place, a scraper being provided which'comprises two parts only in addition to the blade used and which is capable of sustaining the usage toV which a device of this character is put in service. f'

An understanding of the invention may be had from the following description taken i11- connection with the accompanying drawing, 2o in which,

Fig. 1 is a perspective view of the scraper of my invention.

Fig. 2 is a perspective view showing the method of assembly or disassembly of' the which is narrowed to make' a narrow conscraper..

' Fig. 3 isa longitudinal vertical section through the scraper in partially disassembled relation.

Fig. 4l is a similary lview showing. the

scraper completely assembled.

Fig. 5 is a fragmentary side elevation illustrating the scraper in partially assembled form, and

Fig.- 6 is a similar view showing the scraper fully assembled.

Likel reference characters refer to like parts in the different figures vof the draw- 1ng. n

In the construction of the scraper a member of sheet metal is provided of channel form having a web bottom 1 from which'two iianges 2 extend upwardly at opposite sides as shown in Fig. 2. At one end of this member a handle section 3 of inverted channel form is attached partially covering the first channel member. In practicethe two parts are made integral and formed lby suitable dies and tools into the shape shown. The web or bottom 1 directly in front of the handle section 3 has a slot 4 cut therein which is disposed lengthwise of the dev1ce.

The opposite end of the channel memf ber is widened and formed into a base plate 5 from which. at two spaced apart points projections 6 of circular outline are pressed upwardly. At each edge of the plate 5 lips 7 are formed and are turned backwardly over the plate to provide clamping clips for a purpose which will later appear. A scraper blade, which may be either a blade such as is used with safety razors or one of asimilar though heavier construction, may

a clamping plate 12, the width being such that iti'may be received under the clamping clipsv 7. At the oppositeend of the second member the metal is turned downwardly at right angles making an end section 13,

necting section 14, and then terminates in a widerhead 15. i

.With the blade 8 laid upon base plate 5 the section 15 may be passed through the slot 4 by turning the second member of the vdevice at an angle to the first member, as

shown in Fig. 2. The narrow connecting f section 14is slightly less in width than the width of the slot 4 so that the second mem- .ber ofthe deviceY may be turned back to lie ldirectly over the first member described. -Vhen thus positioned, as 'shown in Fig.l 3,

the turned down end member comprised of

sections

13, 14 and 15 is located at the front 'end of the slot 4 and the upper member of the Idevice may' then be lowered to substantially the position shown in Fig. 5, whereupon the rear edges of the clamping plate 12 will come directly in frontof the clamping clips 7. Then by pressing against Vthe section 15 so as to move the second memand against any disengagement from the projections 6, as is evident.

The disassembly of the construction is merely a reversal of the operations described consisting in the movement ot the upper member of the device longitudinally, which .movement may be eil'ected by pressure against the rear side of the section 15 so as to move the narrow connecting section 111 lengthwise of the slot 4. This trees the clamping plate 12 of the clamping clips 7 so that it may be lifted to the position shown in Fig'. 3 and the blade 8 removed for sharpening or replacement.-

, The construction described is very simple but practical. The elimination of screws or other securing devices is a very desirable feature of the present invention reducing the number of parts and eliminating considerable time and trouble in assembling. The device consists of but two parts for holding the blade.

It will be noted that the handle portion 1 of the device is indented transversely as indicated at 16 between the ends of the slot 4. This is for the purpose that on moving the other handle portion 11 with the integral elamping plate 12 longitudinally or to the position shown in dotted lines in Fig. 4L, the inner edges of the part 15 will engage with the indentatiens at 16 holding the device in the position shown in dotted lines in Fig. 4. The edge of the blade 8 will be covered by the clamping plate 12 and a guard thus made so that there is no danger of cutting by the blade when the device is not used or when it is carried in the pocket of aworkman. It is also evident that the movement of the clamping plate 12 from the position which it occupies when the edge of the blade is exposed, as in Fig. 1, to the dotted line position shown in Fig. 4, removes any material which has collected on the blade ahead of the edge of the clamping plate 12 thereby scraping and cleaning the same from the blade.

These are features ot advantage. Paint or putty which adheres to the blade is very quickly and easily removed in this manner.

The construction has proved verypractical and serviceable. The invention is deiined in the appended claims and is to be considered comprehensive oi all forms ot structure coming within `their scope.

I claim:

1. A scraper comprising, one member having a handle portion of channel cross section with a slot cut through the webof said `handle portion, said handle portion at one end being widened to form a base plate,

spaced apart lugs projecting v'from said base plate, a blade located against the base plate lhaving openings into which said lugs eX- tend, a second member having a handle portion'also of channel form inverted lwith respect to the handle portion of the first member and at one end -being widened soas to lie over said blade and base plate, Vand at the opposite end being formed with an inturned locking member adapted to pass through the slot in the web of the iirst handle portion, said locking member being slidable lengthwise of said slot, and clamping means on one oit said plates with which the other engages on longitudinal sliding movement of the Imembers relative to each other thereby clamping` the blade between said plates. Y Y

2. A construction comprising the elements in combination defined in claim 1, said locking member comprising a section wider than said slot where said section joins the handle portion to which it is attached, a second section slightly narrower than said slot and a third terminal section wider than the slot, the length of 'the second and narrowest section being slightly greater than the thickness of the Vmetal from which the first member is made. v

3. A device oi' the class described comprising, two contiguously arranged members having superimposed clamping portions, said members being movable relative to each other, interengaging means on said members near their clamping portions, said means serving when interengaged to retain the clamping portions together and being disengageable by relative sliding movement of the members, and means associatedv with both members remote from the clamping portions serving as a combined sliding and hinge connection between said members.

5. A device of the class described comprising', two contiguously arranged members having superimposed clamping portions, said members being movable relative to each other, intereng'aging means on said members near their clamping portions, said means serving when interengaged to retain the clamping portions together and being disenga'geable by relative sliding movement of the members, and means associated with both members remote from the clamping portions serving as a combined sliding', pivotal and hinged connection, said remote means being separable when the members are disposed in angular relation to eachy other.
