My invention relates to tools for use in repairing boots and shoes and consists particularly in a novel hand channeling'tool.
In certain processes in general use in the shoe making industry and in shoe repairing, it is desirable to cut a channel around the edge of the sol-e and insert stitches, for se- 1 curing the sole to a welt or an upper, beneath the flap loosened by the channeling tool. The flap is then cemented over the stitches and serves as a protection for the same.
Various hand channelers have been developed, but many of these have certain disadvantages which detract from the usefulness of the device. It has been found that in some of these tools there is insufficient guiding structure and hence there is a tendency for the knife to out too deeply into the-- sole leather, while in others, wherein adequate guides are provided, the sole is distorted in passing over the knife so as to be pinched or cramped betweenthe guides and the knife resulting in more dificult opera- The main object of the present invention is to provide a channeling tool in which a knife will be satisfactorily guided through the sole leather in a plane constantly paralleling the leather will not be distorted and cramped between the guides and the knife. I attain this general object and other detail objects in the structure illustrated in the accompanying drawings in which Figure 1 is a top view of my novel tool.
Figure 2 is a side view of the same.
Figure 3 is an outer end view of the tool.
Figure 4 is a vertical transverse section taken on the line 4.- .t of Figure 1 and showing a section through a leather sole being channeled.
The tool includes a handle 1 having a 1ongitudinal recess 20 to receive a pin 2 of any suitable shape which projects rearwardly from the tool head 3. A rivet 4; extends transversely through the handle 1 and pin 2 holds the tool head and handle in assembled relation.
The tool head 3 is provided with a longitudinal cylindrical orifice 5 and is split longi- Knife "8 and guide -'l();preferably contact ,Vguidesi so that :there can be no 1 93 -.seriai ivafsmasoi tudina'llyl at 12, forming ears 6 i and 17'. 1 A screw 11-9: passes through ears '6 yand- )7 Hand serves as an adjusting means to' vary: thesize of :orifice 5 toperrhittheinsertidn: and withadrawal of the. shank of the'knife 8. When-3 assembled for use, knife'S extends perpendicu'la'rlyyof'theend of tool head :3; i The -knife' blade 1 is sharpened along i edge 13 and has a sharpened leading point '14. The lower or bearingv face l5 of the knife parallels-the longitudinal ,axis of the tool head, and is-ri-n 'line with the lower surface lfi of av trailing 7 guide 10' projecting outwardlyzfrom head 3 i and on the side thereof opposite-1 ears .6. and 7.
7 at their adjacent edgesand their lowerisides co-operate to form a continuous plane bearingsur'face; The outer ends of.;knife.8 and rguide'lOv are beveled away' from, their .respec- .tive leadingpointsan'd lower surfaces as shown at 17 and .l8Iin-Figure1. 1
A leading guide. 11 projects forwardly 1 from ear o6 and ;is disposed 'above the" lower "or bearing surface ofknife 8 by'ra distan'ce Tequal to thedesired thickness of the. 'flap to ,be raised from the sole. The edge 19 ,of, guide :11 engages the sole, preventing theknife from :f'cutting too deeply "into the work, and the :lowersurface vof guide '11; is 1 somewhatiinclined to the plane of i'the bearingfface of s o itheknife to facilitate :the passage oftthe guideovejr thenpper surface of-theleather.
In Figured I show my improved tool being used to channel a sole-S; It will be 'noted that thei knife blade is held on a straight course through the leather by; guides -10 and C11 'pos'itionedintzfront and :in "back oflthe knife, respectively, .guide 10 preventing the knife from cutting out? through the top -.o'f the flap 'Fan'd guide 11 preventing theiknife from cutting too .deeply" into the leather H0wever,1the=portion=of the sole: being channeled is not cramped by .being corrugated over the I knife and under the front: and rear r pinching or ir arfnpingtonundulymesist}.the passage of the n n1 e. .i I I i i.Obviously,- itheguides and other parts shown'iin 113116 selected gembodiment may be modified to a certain extent as to shape and knife member having a Hat face with a cutv ting edge, and a guide member having a guide 1 i sui'face in the'pla'nei o'f thejfacfe and edge of said knife member and at theside of said knife member opposite to said cutting edge to control the relative inclination of the knife and the work as they move past each other.
