'Appiication Afiled october 27, 1926-. Serial No. 144,428.

lThe object of my present invention,

broadly speaking, is to vprovide a-combina a. con'iparative- Y ployed in connection lwith framing pictures' or the like to provide-means for trimming off theedges of the backing or sealing paper which has previously-been pasted overgthe back of the frame, for forming holes vin Y the frame for starting screw-eyes, and f oi` turn-,

ing the screw-eyes securely into tlieirpfinal position in said holes. Y

Other lobjects and particular Y advantages of my invention will suggest themselves in, the course of the following description, and

that which is vnew will be broughtl outiii the appended claim. l y

rllie preferred means for carrying out the principles ofmy invention in a practical, ef-A licient, and mechanically correct manner, is shown in th'e accompanying drawings, -in whichFig. 1 is a perspective `view. of my inventioin'as it would appear in actual practice as performing one of its operations;

Sin'iilar indices denote like parts throughout the several views.'

In order that the construction, the operation. and the several advantages of the. Ainvention may be more fully understood and ai'ipreciated, I'will now take up a detailed description thereof, in which I will set forth the same as comprehensively as I may.

In the drawings letter A denotes a por-- tion of a. picture frame or the like, B denotes a sheet of paper which is pasted over the back of the frame, C denotes surplus paper which extends out over the edges of said frame, D denotes the surplus paper which has been cut from the sheet B by my tool, and E denotes a human hand as graspeconomical in use, aiidwliicli can'y ing my tool to perform the icuttingopera.-

i `'lhe Vinvention propery v,includes the body; portion `which consists of sheet ,metalcut into substantially the form shown'. in .F-ig. 2

vandmit comprises the two side portions land 2, rand. a central portion. Formed onathe vopposite edges ofthe sides 1 and i2 are the respective taper portions orflanges 4 and 5,v`

Extending fromwthe outer.. (frear') ,coiner I of the side 1'1is atongue 6 which forms a,

guide, as will hereinafter .bef fi'irthereX-fV plained. r Y Also extending out vfrom the edge of the sidel 1 isy a ltoot-117, thesame being located near the ysmaller-,endofftheyflange 41,?

" Extending out fromthei,forwardendfof i Extendringsfromthe. rear corner of the side 2 is a tongue V9. i 1

Formed between ther tongue 9.and the intot-he form shown in Fig. 2, itis then bent into vthe shapeshownin Figs. 1, 4, 5,6

and '8, as` follows: v Y f Y l i The central portion 3 is bent longitudinally'into tubular form,l whereby -theside's l and are brought `flat together. y

' flhe flangesr 4 and 5 are' then'bent outwardly, directly opposite to-each other, and at right-angles to their respectivefsides 1 and 2' d y ,v

The teeth 7, .8 and 11, extending from the sid-e1, are then bent over andl into cont-,ict with the face' of the i side 2, thereby securing the sides in position and preventing them from springing apart.

The tongue 6 is then bent outward, bringing it atan angle with relation to the side 1, substantially as shown in the drawings.v

The sides of the tongue 9 are then curved toward each other, in order to make the under side of the tongue 9 rounding, as shown in Fig, 5 whereby itr will make a smoothv contact with the edge of the frame.

The forward outer corners of the sides '1,

and 2v are then bent outward, opposite lto eachother, forming the wings 12 and 13, bending them on the respective dotted lines y and e.

Said member 14 is adapted to slide over the smaller ends of the flanges 4 and 5, and as the member 14 is forced toward the larger ends of said flanges it is evident that the sides 1 and 2 will be securely clamped together.

Letter G denotes a cutting blade, which is placed between the sides 1 and 2, with a portion of the edge of said blade exposed in the notch 10, as shown inFig. 5. Said blade can be removed or replaced by simply removing the member 14 to release the lower edges of the sides vbetween which said blade is disposed.

The stem, shown alone in Fig. 3, com-l prises a straight central portion 15, which is round in cross-section, and 1t 1s of such size as to fit snugly in the tubular central portion 3. One end of the stem terminates in a sharp point 16, while its other end Y terminates in a ring 17 Vwhich forms a handle.

In Vpractice the glass,vpicture, and stiff backing is first secured in the frame A in the usual manner. A sheet of paper is then pasted -over the backing and the back of the frame, in order to exclude dust, smoke, and moisture, and this paper projects out beyond the frame,.usually at all four edges of the frame. My tool is then brought into action by resting the guide-tongue 6 on the sealed paper B, with the rounded tongue 9 -atsubstantially right angles thereto and contacting with the outer edge of the frame, thus bringing the juncture of the back of the frame and the outer edge thereof into the notch 10, and thereby bringing the blade G into shearing Contact with the frame.

Therefore if the tool be grasped in ones handy and drawn along the edge of the frame it will cut the paper along the edge of the frame, regardless of the contour of the frame, thereby forming a smooth and peri v feet job.

evident that what remains is the permanent part Bwhich latter extends only to the edges of the frame, as indicated in the foreground in Fig. 1. l

In the next operation the tool is grasped in ones hand and the point 16 is forced into the back of the frame to provide holes in which screw-eyes may be started, said screweyes being for the purpose of securing the ends of a'cord, wire, or chain by Vwhich -theV herein set forth without departing from the spirit of the invention and withou'tsacrificing any of the advantages 'thereof which are new and useful.

Having now fully shown and described my invention, what I claim, and desire to secure by LettersV Patent of the United States, isv A -tool comprising a body including two sides, a tubular portion formed at the juncture of the twov sides and adapt-ed to hold a stem removably therein, a blade located between the two sides, a clamp for detachably securing the blade in position, a tongue disposed at an angle from the corner of one of said sides, a second tongue extending'from the corresponding corner of the other side,

said tongues being located at right-angles lto each other, there being a notch formed in the bodybetween said tongues to expoige a. portion of said blade. Y l v In testimony whereof I have hereunto subscribed my naine to this specification.
