' The invention relates to toolsetting "gaugesl landparticularlyto a gauge for-*setting the cutting tools on billet surfacing machines` of the type disclosed in the patent toV Louis C. Reis; No.

1,659,2647granted May 8', 1928.

Surfacing machinesof the above vtype include a rotating cutter head and grippingV members -movable toward and away from the headV fon passing thebillets therethrough. rThe cutter headA is mounted ina suitablecasing 'and has rotation therein about the axis of the billet -to perform its cuttingaction. Adjustably secured to a carrying ring are a ,pluralityfof cuttingtoolsV and in order for the machines tovaccurately resurface the billets it is essential that the toolsbe set at exactly the same distance--fromthe cutting center. y *Y An'object of the present invention visto provide a .gauge that can be readily 4applied with- .out removing the heavy carrying ring from the machine and which will enablel the operator to` .'ly set tools withv precision and which will-be simple 4Vin construction and fulfill all requirements vof service and manufacture. Y

With these vand various othenobjects in View, the invention may consist of certain novel features of construction and operation as willfbe more fully described and particularlypointed out in the specication, drawing and claims appended hereto.

In the'drawing which illustrates an embodiment of the device and wherein like reference characters are used to designate like parts- Figure l is a front view of the cutting mechanism showing the gauge of the present invention applied thereto; Y s

The present invention, although of broader application, is shown in the drawing as applied to that form of cutting mechanism employed in billet surfacing machines and which includes a tool carrying member I having secured to its face arcuate members Il by means of bolts I2,

includedfasfpart of the cutting mechanism is an adjusting ring ,I4v positioned concentric `with V the arcuate membersllfand receiving threaded adjusting bolts I5 which are locked in position the ringby thelock nut I6. A` groove I1 isv vprovided in the face `of* theladjusting` ring for vpurposes which will be -presently"described,the groove connecting a plurality of spacedV threaded fre'cesses I8- V located adjacent VAeach adjusting bolt I5v."r` 'j A '1` j i The tool setting gaugebymeans of which the cutting tools I3'lcanlbe` accurately positioned` Ain `the tool carrying member incldes`anfarm` having secured to fits vertical iacel the 'wearplate 2| and receiving an adjustmentblock 22 which by means'of the `bearing"plate 23 and set adjacent one. of` the graduations 25, depending 'on the'particular site of billet tov be resurfaced. Secured Yto one face of `the adjustment block `is a` guideplate l for receiving Va portion "of the indicating member-pivoted to one end of the `bloclr bythe screw 2'I'and including'a head portion 28 and an indicating4 arrow 3l).tz By'. means of thecoil spring 3|, which has engagement with oneend of theiiug 32vprovided`on` the arrow 30 yand at its other end with set screw 33, the irldicatingv arrow is resiliently urged in 1a.downthe tools I3.

Wear-plate 2I,'secured to the face of thejarm 20 yscrew 24'may be lockedin Vpositionon the' arm `3'0y 'ward directionin order to maintain engagement y between the". head 28 andthe cutting edge of,

As rmore particularly lshown in Figure 3` the v by screws 34, is provided with an arcuate `rib Y adaptedv to have Vinteriitti'ng engagement with the groove I1 formed inthe face of the adjust- Y ing ring. Extending through bore 35 is a locking screw 36 threadedjat one end andhavingv pivotally secured tothe other end a handle 31, the threaded end being adapted for threaded engagement with the recesses `I8 wherebyy the gauge arm-'is rigidly' secured to the adjusting ring with correct positioning of the larm being assured by the interfltting engagement of the ribl formed formed on the wear-plate and the groove in the adjusting ring.

In operation of the 'cutting mechanism l,the cutting tools soon wear, *requiringV frequent re grindingY and resharpening. Each tool may be removed from the mechanism without4A disturbing the setting of the other tools by merely loosening the bolts I2 and Vremoving thektool-through the cutting opening. It is `desirable when removal of any of the parts of the cutting Vmechanism. VThe arm 20 is secured to theY adjusting ring 'I4 bythe locking screw '36'adjacent the particular cutting tool which has been replaced.

The adjusting-bolt .I is first loosened androtated outwardly of the casing so as to allow insertion and positioning of the 'cutting tool outwardly of the circle defined by their inner sharpened edges and the adjustment block v22V lis positioned on the arm atV the'particular graduation for the size billet being resurfaced. 'The resilient means 3| forces the indicating .arrow downwardly and the head 28 upwardly into engagement with the cutting tool and Linofrder 'to rcorrectly positionthe latter fit is onlygnecessary to :rotate the bolt I5 in that direction vto force the cutting tool downwardly which effects rotation of thefindicating member. When theY arrow V:311 .is opposite the 'indicating mark 3B the/bolts -IiZ-rare :then`tightened to rigidlysecure the tool in Y place-and the nut I6 is likewise rotated to lock @the yadjusting 'bolt in position. If desirable a `4check on the-adjustment of'thejcuttingtools fcanebe :easily made in thersame manner to infsurethat correctl positioning of the same with respect to each other has been accomplished.

-Itis toV bie-understood that I do not wish to vbe limitedby the exact embodiment ofthe device shown, whichis merely by way of `illustration and notlimitatiom as various and other forms of the devicewill of course be apparent to those :skilled in the art without departing from theV the scope `of Ythe claims.
