.my JOHN H.'WELiLER ANZI)V ROY S. NEWTON, OIE NEW HAVEN, CONNECTICUT, ASSIGNORS TO l SARGENT & COMPANY, OF NEW HAVEN, CONNECTICUT i PLANE particularly to a plane having an adjustable bit -tor varying ythethickness of the chips cut bythe plane. l y l f In the usual plane the plane of'the bit bears a fixed angular relationship to the bottom of the plane which limits the utility ofthe plane andthe quality of work which may be accomplished therewith.

16- yThe general object of the'present--invention is to provide aplane in which the angle of' thebitmay be varied according to the depth of ,the cutor character of the grain d of 'thewood acted on.

of. theinventionj to provide a plane having a bit supporting frog which is adjustable with respectto the bed ofthe plane whereby the y plane of the bit may be readily varied with A respect to the` bottom ofthe plane.

A` further object of the invention is to provide a plane invwhich chips are prevented from passing into the plane through the throat except in front of the bit.

To4 these and other ends, the invention consists lof the novel features and combination of parts to be hereinafter described and claimed. l 1

`Referringzto the drawings in which we have yshown afpreferred embodiment of our v`invention, the reference numeral 10 indicates in general the stock or bed of the plane,

' which is preferably made out-'of metal and is' rof the usual cross sectional shape. The Y fronti handle, of usual type, is indicatedA at 50"'11, while the reference numeral 12-indicates Our' invention'relates to a plane and more` In amorel specific aspect it is an objecty v24 about the axis of pin 25.

i Application'rled January 7, 1930. Serial No. 419,054'.

the rear handle also of usual type. The bitV or plane iron 13 is clamped against a frog 14 by means of clamp 15 which is provided with the usual clamping inger 16, the usual screw 17 passing through the clamp and into the frog 14 to secure theclamp to the frog; At the lower rear part, of the frog 14, the latter carries a projecting lug 18 in which" the lower end portion of adjusting screw 19 is freely rotatable. The opposite or upper end of adjusting screw 19 has a bearing` in a lug 20, projecting from the rear upper portion of the frog 14 and similar to` lug 18. Axial movement of screw 19 in one direction is prevented by milledhead 21, and in the opposite direction by collar 22 and pin 23, collar 22 bearing against the lower face of 'lug 18, while milled head 21 rests on adjusting lever 24, which is provided near one end thereof with a pin 25 received in an opening in lug 20. Lever 24 is provided with anose 26 received in a longitudinal slot 27 in plane ironr 13 and provides for the transverse adjust;r ment of plane iron 13 by movement of lever Received on screw'19 between lugs 18 and 20 and provid-' ing for the longitudinal Aadjustment of plane iron 13 is a nut 28 having its inner end received in a slot 29 in frog 14 and havy ing a linger 30 which may be received in one of a'plurality of openings 31 in plane iron c transversely through the bed of the plane and through the lower end of the frog.

-The bedy of the plane is provided with'a thickened portion 33 Vwhich is channeled at f 34 for the reception of wedge 35, which is supported for movement towards and away from frog 14 on bearing surfaces 36, 37 38 l and 39, wedge 35 being provided with'a sub-` stantially semi-cylindrical upper surface 40,

which engages the under sidey of frog 14,4 as at 41 and 42, and by movement of wedge @69 Vand :bit 5.7 ,against frog 55.

along bearing surfaces 36, 37, 38 and 39 swings frog 14 `about pin 32. Wedge 35 may bel readily moved along bearing surfaces 36, 37, 38 and 39 by means of milled Vnut 43, which is provided with a groove or lreduced portion 44 in which spaced lugs 45 and 46 on4 plane bottom 10 are received, nut 43v being threaded for the reception of threaded stem 47 having at one end thereof a reduced portion 48 fixed in wedge'35, vthe end of stem 47 being `headed over at 49to prevent axial movement of stem 47 with re spect to wedge 35.

Frog 14 is vprovidedwith arecess 50, at the lower end of which is a chamfered opening 51 for thereception of screw 52,` the lower end of which is received in threaded opening 53 in plane bottom v10. When frog 14 has beenadjusted to any desired position by movement of wedge. 35, screw 52 serves to force frog 14iagainst wedge 35,

yschrew52 and wedge 35 cooperatingto hold the frog immovably in place.

The plane shown in Figures 5 and )6 of the drawings is provided with a bed 54 on Y which frog 55 is mounted for pivotal movement by means of pin 56 passing transversely through bed 54 and through the lower end of frog 55, frog55 vserving to support bit 57. Longitudinal movement of bit 57 is effected in the more or less usual manner by means of lever 58 pivotally supported on pin 59 in frog 55, lever 58 being provided at one end with va nose 60, and at the other end with` -a yoke, which is received in a groove 61 in nut 62, the latter having a'threaded axial opening 63 infwhich threaded stem 64 is received, stemf64 being fixed in the usual manner in frog 55 and extending rearward- :jly therefrom. Transverse movement of bit 57 is effected inthe usual manner by means.

of lever 65, pivotally supported on the upper end of frog 55, at 66, and-having a nose 67 which is received in the usual longitudi- -fnal slot 68 in bit 57. The usual clamp 69 is secured to frog 55'by means of screw VV7,0 whichextendskv through enlarged opening 71 in frog 55 and is received Vin a threadedv opening 72 in lug 7 3` of bed 54.

a. `Mounted on thethreaded end ofV screw between lug 7 3 and frog 55' are milled nuts thereby, the angle of bit 57 with respect Y. .tothe-bottom of the plane, may be readilyr varied by adjusting the .position of screw 70 in opening72,'nut 75 serving to lock the screw in any position of adjustment.

The cutting .edge 78 of bit 57 extends .i-cthrough opening 79 in bed 54, thegposition .means is adjusted. 74 and 75, ofwhich lnut 74 engages the' ly lling theV opening behind `bit 57 .i v'Plate' 80 isautomatically adjusted in position as frog 55 is adjusted by means of link 82,

one end of which is mounted in slot 83 in frog55on pin 84, while the opposite end is mounted Von pin 85 inl bell crank lever 86.

Lever '86 Vis mounted .on pin 87 in bed 54, and is provided with a linger 88 received in a suitable opening in plate 80. As frog 55 is adjusted by means of screw 70 and nut 74, link 82 swings lever 86 to maintain the edge 81 of behind bit 57. Y

,It will be' readily understood from the above description of the invention that we have provided a plane in which not only may the plane of the bit be adjusted with respect to the work engaging faces of the plane, but also'a plane in which provision is made for preventing chips from passing into the plane except through the throat normally intended to receive the chips.

While we have shown preferred embodiments of our invention, it will be understood that it is not to belimited to all the details shownbut is capable of modification and variation within the spirit of the. in-
