1 Claim. (Cl. 145-4) This invention relates to a portable power plane and i more particularly means for fastening in place on a power plane a deector for shavings removed by the rotary blade of the machine.

Shavings removed by the rotary blade of a power plane are normally forced through a passage in the housing of the plane and ejected from the machine in a direction away from the operator.

It is a principal object of this invention to provide a; removable deflector through which shavings removed by the blade are ejected to one side of the machine, and. which may be reversed in order to eject shavings to the: opposite side of the machine.

It is another object of this invention to provide means: for fastening the removable deector in place on the machine in both its first and reversed positions. It is a.

further object to provide a deflector which slides into place on the machine in ways provided with a latch and anti-- rattle structure, preventing the detlecto-r from being; loosened by vibration accompanying operation of the.y plane and securely fastening the deflector in its positions..

It is a further object to provide the power plane with. a bevelling guide so that the unit may be used as an edge planer or a door plane, the bevelling guide incorporating slide way for receiving a detiector 21 slidable in the way. The deector 21 serves to detiect shavings received from the blade and ejects the shavings to one side of the machine. The plane 10 as shown in Fig. l has a deflector 21 which ejects shavings in a direction away from a right handed operator, to the right hand side of the plane.

an angularly adjustable fence and means allowing the. j

fence to be shifted easily from one angle to another and.

located in place.

Further objects will appear from the following descrip* tion read in connection with the accompanying drawings,


Fig. l is a View in side elevation of the power plane of. 31"

Fig. 6 is a section similar to Fig. 4 but with the de? ector reversed;

Fig. 7 is a detail sectional view taken along lines 7T i of Fig. 2; and

Fig. 8 is a detail view showing the angularly adjustablepivotal support for the bevelling guide.

A power plane 1t) of a conventional type is shown in. Fig. l poweredpby a motor hidden behind the fan shroud. 11 through a belt drive 12 turning a rotary blade 13- rotatably supported in the housing 14 of the unit. The rotary blade 13 extends through an opening 15 in the shoe 16 which is flat and rests directly against the work. when the machine is operated. Projecting below the shoe the blade 13 removes shavings the thickness of which is determined by adjusting a shoe 17 supported on the forward part of the machine.

Shaving-s removed by the blade 13 are forced upwardly through -a passage 18 extending above the blade to an'. opening in the top of the housing. On the top of thehousing 14 there is mounted plate 19 provided with a- (die The plane 10 may be used as a surface planer or, when provided with the bevelling guide 22 it may be used as an edge planer or door plane. The bevelling guide 22 Acomprises a fence 23 angularly adjustable with respect to the bottom surface of the plane. Brackets 24, 25 are pivotally supported on arms 26, 27 fastened on the plane 1t?. 'Ehe pivotal support is provided by means of rivets 23 (Fig. 8) passing through companion pairs of arms 2o, 27 and brackets 24, 25. The brackets 24, 25 are punched with aligned curved slots 29, and a shaft 3l? passing through the slots 29 may be turned by a small thumb wheel 31 to tighten the assembly and securely lock the fence 23 in position.

Deiiector 21 mounted on top of the power plane 19 over an opening 35 at the end of the passage 18 leading tto the rotary blade 13, shown in Fig. 2 to consist of a casting or stamped part, is formed with a curved inner end wall 36 and an inclined back wall 37 which combine to deflect shavings forced through passage 18 and the opening 35, to one side of the machine.

In order to secure the deliector 21 in place a plate 19 is fashioned to rest on a base provided by the tlat top 58 of the housing 14. The plate 19 has an opening with substantially parallel edges or rails 411, 41 (Fig. 3) on which the deilector 21 slides, and in order to lock the ldetlector in place on the plate, undercut grooves 42, 43 providing a slide way for the deiector 21.

Extending into the grooves 42, 43 are narrow anges 44, 45 on the lower rirn of deector 21. Vertically spaced above the narrow anges 42, 43 is a narrow projecting wall 46 which extends along both sides of the lower outside portion of deliector 21 and provides a flat lip resting on the rails 40, 41 of the plate 19. The narrow flanges 44, 45 and the lips formed by the protruding wall 46 embrace the rails 40, 41 in the plate with considerable play being allowed between the flanges and the walls of the grooves.

ln order to hold the deilector in position and prevent it from rattling due to vibration set up by rotating parts of the machine, cavities 55, 56 in the plate 19 are provided registering with grooves 42, 43. As shown in Fig. 5 which is a View looking upwardly toward the underside of the plate 19, there are two cavities 55, 56 in the plate, each of which has a flat end Wall 57, :'58 substantially parallel with the rails 41, 42 and lugs 59, 60 extending into the cavities. The side walls 61, 62 of the cavities taper toward an opening 65, 66 communicating with the adjacent groove under the rail 40, 41.

The lugs S9, extending into the cavities are positioned between the end portions of at springs 73, 74 bent into a triangular or inverted V shape and contained within the cavities. The springs 73, 74 project into the adja- :cent grooves 42, 43 of the plate 19. ln order to latch the ydeflector 21 in position in the slide way, notches 80, 81 are fashioned in the flanges 44, 45 into which the springs 73, 74 extend. The side walls of the notches 80, 81 are .slanted so that the deilector may be removed from the .slide way by the application of pressure deforming the the springs lock into position in the notches and latch the deflector in place.

Thus in addition to locking the deflector in place, preventing endwise movement and removal of the deector until the application of suticient pressure to deform the springs so that they allow deflector to be withdrawn from the ways, these springs also serve to prevent the deflector from vibrating due to the vibration set up by the rotating parts of the unit, the motor and rotary blade.

The power plane is equipped with a bevelling guide 22 for the making of bevel cuts with the plane. By adjusting fence 23 at 90 to the bottom surface of the plane square cuts may be made such as are required in finishing the edges of doors and windows. In this application the power plane is termed a door plane.

In order to allow thefence 23 to be angular-ly adjusted, brackets 24, 25 welded on the fence are pivotally supported on rivets 28 fastened to arms 26, 27 carried on the housing of the plane 10. In order to lock the fence 23 in the different angular positions, curved slots 29 are provided for receiving shaft 30. Intermediately of shaft 30 inside brackets 24 and 25, there are fastened washers 8S, 36 which abut against the inside of the brackets 24, 25. The free end 87 of the shaft 30 is screw threaded to receive a nut 88 which bears against arm 26. To prevent the nut 8S from rotating a lug 89 (Fig. 8) struck out from the arm 26 is used, presenting a at surface to one side 90 of the hexagonal nut 88.

The screw threads provided on the free end 87 of shaft 30 are of right hand, so that by rotating shaft 30 clockwise the nut 88 is drawn up toward Washer 85 squeezing arm 26 and bracket 24 together, and the bracket 24 is securely held against the arm 26 by the nut 88.

Likewise, when the shaft 30 is turned counterclockwise the nut is moved away from washer 85 relaxing the pressure forcing the bracket 24 and the arm 26 together, so that these parts may be moved relative to each other.

The end of shaft 30 adjacent the Wheel 31 is also screw threaded to receive a nut 95 and a lug is struck out of arm 27 iitting against one side of the hexagonal nut 95 to prevent its rotation, as has been described in connection with the nut at the other end of the shaft 30. The screw threads provided at the end 94 of the shaft 30 adjacent the wheel 31 are left hand as contrasted to the right hand threads at the free end of the shaft. This is in order that the nuts S8, 95 at both ends of the shaft 30 may be drawn up toward their respective Washers 85, 86 to lock the brackets at both ends of the fence against the companion arms by rotating shaft 30. For example, by turning the shaft 30 clockwise the nut 88 at the free end of shaft 30 is drawn up to tighten the bracket 24 against arm 26 and the nut 95 at the other end of the shaft is drawn up to tighten the bracket 25 against the arm 27. By turning the wheel 31 counterclockwise, and consequently rotating the shaft 30 counterclockwise, both nuts 88, 95 are loosened and the fence 23 unlocked so it may be angularly adjusted from one position to another.

In using the power plane 10 as a surface plane, an electric cord 96 is plugged into a convenient electric outlet, and the unit grasped by means of handle 97 and handle 9S, provided by deector 21. As has been described hereinbefore, if the power plane 10 is to be used as a surface plane, the fence 23 must rst be removed. This is done by loosening bolts 99 and removing the entire guide assembly.

The handle 97 is a pistol grip type with an on-off switch 100 for the motor driving the rotary blade 13 of the plane. Deector 21 is formed exteriorly to provide a handle on the forward part of the plane 10 and may be gripped in either the left or right hand depending upon the nature of the work and the inclination of the operator. It is normally desirable to eject shavings from the machine to the side away from the operator, so that the plane arranged with the deilector 21 to eject chips to the right hand side ot^ the plane would be used by a right hand operator handiing the plane at his side in the usual fashion. The deector 21 may be removed and reinserted so that the opening 101 in the end of the dellector is directed to the left hand side of plane 10, the arrangement rnost convenient for s hand operator handling the plane as he is accustomed.

Removing the deector 21 requires only that suicient pressure be applied endwise to the deilector to slip the springs out of the notches in the flanges on the deector, and it then may be reinserted just as easily in place. It will be observed that the cavities containing the springs are on opposite sides of the opening in the plate and are staggered with respect to each other, as shown in Fig. 4, so that the deflector will be properly located over the opening whether arranged to eject chips to the right or to the left side of the machine.

Although the t between the deflector member 21 and the slide way is loose, the deector member is prevented r from rattling due to vibration set up by the rotating parts of the machine, by the springs seated in the cavities provided adjacent to the slide way and bearing against the ilanges on the lower rim of the deflector member. Thus the springs serve not only to lock the deflector against endwise movement and consequently enable its use as a handle on the `forward part of the machine as well as locating it properly in place over the opening to the passage in the housing, but also serve to prevent the dellector member from rattling and constitute in the arrangement disclosed an antirattle structure.

The invention has been described with reference to particular preferred embodiments and it is understood the details are merely illustrative and that the invention may be carried out in other ways without departing from the true spirit and scope of the appended claim.

We claim:

A latch and antirattle structure for securing a chip deflector to a power plane comprising a housing member provided with parallel rails, grooves undercut below said parallel rails forming a slideway, said member having cavities in registration with the grooves, said cavities having one 4end wall extending parallel with the grooves and side walls tapering to a narrow opening conirnunicat ing with the grooves, said detlector slidable in said slideway and having narrow flanges extending into said grooves, said flanges having notches therein, springs bent into a V shape seated in said cavities against said end wall with an apex portion extending through the openings into the grooves and bearing against the deflector, for engagement in the notches provided in the flanges of said deflector to resiliently secure and locate said member and said deector with respect to each other.
