As shown, the knife blade is curved in the are of a circle, and is formed upon the periphery of a tlat disk which is provided with a notch, one side of which forms the cutting edge of the knife. The grooving knife is secured to the slide by means of a stud 17 projecting laterally from the center of the disk, and held in a.split clamp formed in the lower end of the slide 9 by a clamping screw 18. By this construction, the grooving knife may be given a rotary adjustment to bring the cutting edge of the kniferinto the required position as the blade of the knife becomes worn away in re-grinding it, and may also be given a lateral adjustmentto vary the distance of the groove from the edge of the welt. Also the arrangement of the blade of the groov ing knife in the are of a circle permits the knife to be so placed in the machine that the portion of the knife directly back of the cutting edge extends in the direction in which the welt strip is fed, the cut'surface of the strip being tangential to the groove of the knife blade, The knife blade thus cuts to the best possible advantage and the chip orstrip removed by the knife passes easily over the upper surface of the blade.

In order that the depth of the groove which is formed in the welt by the grooving knife may be regulated as desired, the presser foot is so mounted lthat, it maybe adjusted on the slide 9` to vary the extent to which `the grooving knife projects below the surface of the presser foot. For this purpose the pressen foot is provided with a vertically extending portion 19 arranged to en gage one side of the slide 9, and provided with a' guiding rib 2O which fits within a guiding groove formed in the face of the slide. The presser foot is held in position upon the slide by means of a clamping bolt 21 which passes through ay slot formed in the vertical portion 19 of the presser foot, and. is threaded into a hole in the slide. The means for vertically adjusting the presser foot upon the slide 9 consists of an adjusting screw 22 vided with a flange 23 engaging a recess formed iu the vertical portion 19 of the presser foot.

'lhe welt beveling knife is indicated at` 24, and consists of a flat disk notched or cut away to provide a cutting edge. The disk is secured in position-by means of a stud arranged in the slide, and pro' projecting laterally from the center of the disk, and entering a split clamp 25 in which it is held by means of a clamp screw 26.

mounted upon a block 28 so as to be capable of an angular adjustment to change the angle of the bevel produced by the knife on the welt strip. The plate 27 is provided with a curved rib 29 which enters a curved slot formed in the block 28, and the rib and slot are substantially concentric with the point of operation of the knife on the Welt,

so that an angular adjustment of the plate produces no substantial displacement of the knife with relation to the Welt. The knife carrying plate 27 is heldin adjusted position by means of a clamping bolt 30 passing through a slot in the plate and threaded into the block 2,8. To vary-the depth of the cut produced by the beveling knife, provision is lnade for adjusting the block 28 vertically. As shown, the block 28 is arranged to engage a vertical surface 31 formed on the frame of lthe machine, and is provided With a guiding rib 32 which tits within a guiding slot formed in the surface 31. The block is held in adjusted position by means of a clamp bolt 33 which passes through a slot 34 formed in'.v

the block, and is threaded in a hole in the frame. l i

The welt strip` is fed through the machine by a power operated feeding mechanism which acts to impart a continuous feeding movement to the strip. This feeding move? ment comprises a driven feed roll 35- andia spring pressed pressure roll 36 between which the welt strip passes, and by which the strip is pulled through the machine against the action of the grooving and beveling knives.

shaft 3S which carries the roll. To enable tlm-machine tobe thrown into and out of operation, a loose pulley 39 is mounted upon the feed shaft 38, and a belt. shifting device 40 is provided for shifting the belt on to either the fast or loose pulley at Willl The belt shifting device is secured upon a shipper rod fll which extends from the front of the machine, where it is provided wit-h a'handle 4-2 by meansof which it may be conveniently actuated by the operator in throwing the machine into and out of operation.

lVhen a welt strip is to be inserted in the machine, the spring pressed side guide 5 should be retracted, and to enable this to be conveniently done, connected mechanism is provided through which the operator may cause the presser foot to be raised, and the The roll 35 is driven through a: belt passing over a pulley 37 secured to the sidrfuiile ln he rerrn-hal. ln ihe reuslrui' presser feel, and separ: lingT lhe leed rnlls7 'lian shown ilw lower end eif ille prrsfs'er l'nnii si|l `=lanin|lly as desrrilued.
