Definitions
- the present invention relates to an electric hand plane comprising a frame, a rotatably mounted cutter with at least one planing tool and with a driving member at one end of the cutter, and an electric motor carried by the frame and which, via a drive arrangement, drives the driving member and thereby the cutter, the hand plane having a main support surface which defines a main working plane tangent to the planing tool in its working position, the cutter being conical with the cutter spindle forming an angle with the working plane corresponding to half the angle of the cone.
- a plane of this type is known through West German Utility Model publication G 78 33 580.
- This publication shows a plane having a conical cutter supported at its smaller end. Rabbeting may be carried out with the larger cutter end.
- the purpose of the present invention is to avoid the above disadvantages and provide a hand plane whose conical cutter is sturdily supported while still allowing unlimited depth of cut.
- this is achieved with a hand plane in which the cutter is supported in the frame at both its ends in such a way that at the larger cutter end all parts of the hand plane, i.e. the cutter as well as the bearing and those parts of the frame which support the cutter spindle at the larger cutter end, are located to one and the same side of the lateral plane perpendicular to the main working plane and touching the larger cutter end at the point thereof lying closest to the main working plane.
- a lateral support is pivotally jointed to the plane frame about a pivot axis extending next to the main working plane at the larger end of the cutter and perpendicular to the cutter spindle, the angle of said lateral support relative to the lateral plane being adjustable with setting means for setting the angle between the main working plane and a secondary working plane formed by the lateral support.
- the cone angle and the height of the hand plane can be kept relatively small if the driving member of the cutter is placed at the end of the cutter opposite to the lateral plane. Then the cone angle only needs to be large enough to create sufficient axial space at the cutter end of larger diameter for bearing, but not driving, the cutter.
- the cutter is preferably belt-driven even if other drive means are conceivable, for example via chains or gears.
- the larger cutter end is provided with lateral planing tools, which are preferably adjustably mounted on the cutter so that their cutting angle can be set at an angle to a plane normal to the cutter spindle. This permits easy planing of dove-tail grooves, for example.
- the hand plane has a frame 1 the flat bottom surface 2 of which forms its main working plane.
- the rear portion of the hand plane as seen to the left in Figs. 1 and 2 has a handle 3 upright from the frame 1, with a switch 4.
- This switch operates an electric motor 5 fixed to the frame 1, and which has a belt pulley 6, not shown in more detail here, on the left-hand side of the hand plane.
- the electric motor 5 drives a belt pulley 8 which is non-rotatably mounted on one end of a spindle 9.
- the spindle 9 is mounted in the frame 1 with a ball bearing 10 next to the belt pulley 8.

- the seat 13 is sealed against dust by means of a cover 14 which is held in place by a lock ring 15 in the outer portion of the seat.
- the cover 14 also holds the outer ring of the bearing 11 in contact with the bottom of the seat 13.
- the spindle 9 carries a cutter 16 non-rotatably joined thereto.
- the cutter 16 is conical with a cone angle 2a with its narrower end at the left-hand bearing 10.

- the parts of the bracket 12 located outside the end of the cutter 16 have small axial dimensions.
- the cutter 16 is provided with two diametrically disposed planing tools 17 removably mounted in the cone surface.
- the spindle 9 is arranged at an angle a to the bottom surface 2 of the frame. This angle a corresponds to half the cone angle 2a, so that the planing tools 17 in their bottom positions will make contact along their entire length with the working plane defined by the bottom surface 2.
- the ends of the planing tools 17 at the wider end of the cutter will lie laterally outside the bearing 11 and the bearing seat 13 when in the lower position, i.e. in the working plane.
- the entire cutter and its bearings, as well as all the other parts of the hand plane, thus lie on the same side of a lateral plane 18 which is perpendicular both to the working plane 2 and to the orthogonal projection of the cutter spindle 9 onto the working plane, and which is tangent to the wider end of the cutter 16 at the working plane 2.
- the hand plane is provided with an adjustable lateral support in the form of a flat plate 19 which is pivotally hinged 20 to the frame 1, Fig. 4.

Abstract
The invention relates to an electric hand plane with a preferably belt-driven cutter (16) provided with planing tools (17) about its outside surface. The cutter (16) is conical and arranged with the cutter spindle (9) at an angle to the working plane (2), said angle being half of the cone angle (2a). At the end of the cutter (16) which has the larger diameter, the bearing (11,13) of the cutter spindle (9) as well as the other parts of the hand plane are disposed on the same side as the cutter of a lateral plane (18) perpendicular to the working plane (2) and touching the short side of the planing tools (17) when they are in the working plane (2). The hand plane can thus work right up to a wall or edge upright from the workpiece. The larger end of the cutter can be provided with lateral planing tools for planing such a wall or edge. The hand plane also has an adjustable side support in the form of an angularly adjustable plate for contact with a side wall.
Description
- The present invention relates to an electric hand plane comprising a frame, a rotatably mounted cutter with at least one planing tool and with a driving member at one end of the cutter, and an electric motor carried by the frame and which, via a drive arrangement, drives the driving member and thereby the cutter, the hand plane having a main support surface which defines a main working plane tangent to the planing tool in its working position, the cutter being conical with the cutter spindle forming an angle with the working plane corresponding to half the angle of the cone.
- A plane of this type is known through West German Utility Model publication G 78 33 580. This publication shows a plane having a conical cutter supported at its smaller end. Rabbeting may be carried out with the larger cutter end.
- The disadvantage of supporting the cutter at one end only is that the bearing arrangement necessarily becomes expensive and space-consuming if the free end of the cutter- is to be prevented from resiliently moving up when the plane is pressed against the workpiece during work. In spite of this, vibrations may arise and the width of the plane is substantial. If, in order to lessen these drawbacks, the conical cutter were provided in a conventional manner with bearings at both ends, the maximum depth of cut is decreased to less than half the diameter of the larger cutter end.
- The purpose of the present invention is to avoid the above disadvantages and provide a hand plane whose conical cutter is sturdily supported while still allowing unlimited depth of cut.
- According to the invention, this is achieved with a hand plane in which the cutter is supported in the frame at both its ends in such a way that at the larger cutter end all parts of the hand plane, i.e. the cutter as well as the bearing and those parts of the frame which support the cutter spindle at the larger cutter end, are located to one and the same side of the lateral plane perpendicular to the main working plane and touching the larger cutter end at the point thereof lying closest to the main working plane.
- Since all parts of the electric plane are located to one side of the lateral plane, planing is possible right up to a lateral surface of any height.
- According to a preferred embodiment of the invention, a lateral support is pivotally jointed to the plane frame about a pivot axis extending next to the main working plane at the larger end of the cutter and perpendicular to the cutter spindle, the angle of said lateral support relative to the lateral plane being adjustable with setting means for setting the angle between the main working plane and a secondary working plane formed by the lateral support. With this embodiment it will be possible to put the hand plane with its secondary working plane against a workpiece and to move the hand plane during work with the cutter spindle substantially perpendicular to the workpiece. The angle of the support surface, and thereby of the secondary working plane, with the main working plane can thus be selected to be greater or less than 909. In order for the angle to be able to be selected less than 90°, it is necessary that all of the parts of the hand plane frame be spaced from said lateral plane.
- The cone angle and the height of the hand plane can be kept relatively small if the driving member of the cutter is placed at the end of the cutter opposite to the lateral plane. Then the cone angle only needs to be large enough to create sufficient axial space at the cutter end of larger diameter for bearing, but not driving, the cutter. The cutter is preferably belt-driven even if other drive means are conceivable, for example via chains or gears.
- According to a further development of the inventive idea, the larger cutter end is provided with lateral planing tools, which are preferably adjustably mounted on the cutter so that their cutting angle can be set at an angle to a plane normal to the cutter spindle. This permits easy planing of dove-tail grooves, for example.
- One example of the invention will be described below in further detail with reference to the accompanying drawings, of which
- Figs. 1 and 2 show an electric motor-driven hand plane as viewed from the side and from above, respectively,
- Figs. 3 and 4 show sections along the lines III-III and IV-IV respectively in Fig. 1, and
- Fig. 5 shows the cutter alone as seen from the rear (from the left in Fig. 1).
- The hand plane has a
frame 1 theflat bottom surface 2 of which forms its main working plane. The rear portion of the hand plane as seen to the left in Figs. 1 and 2 has ahandle 3 upright from theframe 1, with a switch 4. This switch operates anelectric motor 5 fixed to theframe 1, and which has abelt pulley 6, not shown in more detail here, on the left-hand side of the hand plane. Via adrive belt 7, theelectric motor 5 drives abelt pulley 8 which is non-rotatably mounted on one end of aspindle 9. Thespindle 9 is mounted in theframe 1 with a ball bearing 10 next to thebelt pulley 8. At its other end, thespindle 9 is mounted by means of a ball bearing 11 in abracket 12 screwed securely to theframe 1 and which is made with abearing seat 13 for thebearing 11. Theseat 13 is sealed against dust by means of acover 14 which is held in place by alock ring 15 in the outer portion of the seat. Thecover 14 also holds the outer ring of thebearing 11 in contact with the bottom of theseat 13. - The
spindle 9 carries acutter 16 non-rotatably joined thereto. Thecutter 16 is conical with a cone angle 2a with its narrower end at the left-hand bearing 10. The right-hand end of thecutter 16 has a larger diameter and has a centralaxial recess 16a, which encloses thebearing seat 13 and part of thebracket 12. The parts of thebracket 12 located outside the end of thecutter 16 have small axial dimensions. - The
cutter 16 is provided with two diametrically disposedplaning tools 17 removably mounted in the cone surface. Thespindle 9 is arranged at an angle a to thebottom surface 2 of the frame. This angle a corresponds to half the cone angle 2a, so that theplaning tools 17 in their bottom positions will make contact along their entire length with the working plane defined by thebottom surface 2. As a result of the incline of thespindle 9, the ends of theplaning tools 17 at the wider end of the cutter will lie laterally outside thebearing 11 and thebearing seat 13 when in the lower position, i.e. in the working plane. - The entire cutter and its bearings, as well as all the other parts of the hand plane, thus lie on the same side of a
lateral plane 18 which is perpendicular both to the workingplane 2 and to the orthogonal projection of thecutter spindle 9 onto the working plane, and which is tangent to the wider end of thecutter 16 at the workingplane 2. - The hand plane is provided with an adjustable lateral support in the form of a
flat plate 19 which is pivotally hinged 20 to theframe 1, Fig. 4. The axis of thehinge 20 runs parallel to theworking plane 2 and perpendicular to thecutter spindle 9. The axis is located as close to the intersection of theplanes plate 19 is swingably jointed 21 at its top with one end of a threadedpin 22, the opposite end of which can be screwed into a threaded hole in anear 23 projecting upright from theframe 1. By means of awheel 24 non-rotatably fixed to the pin, thepin 22 can be screwed in or out of theear 23, thereby swinging theplate 19 about thehinge 20. Fig. 4 shows theplate 19 in the maximum swung-in position, in which the support surface formed by the plate forms an acute angle with themain working plane 2. When theplate 19 forms a right angle with themain working plane 2, its supporting surface lies in thelateral plane 18. Theplate 19 can also be set at an obtuse angle with themain working plane 2. - As can be seen from Figs. 1 and 5, the
cutter 16 is provided at its wider end with twolateral planing tools 25 arranged incavities 26 in the end of the cutter. Eachtool 25 has the shape of a circular sector of less than 90°, theedge 27 being formed by a radial limitation and lying next to the end of the cutter. Next to the periphery section, thetool 25 has an arcuate slot 28 through which a lock screw 29 projects with a loose fit. At its point, thetool 25 has a slot which is essentially parallel with theedge 27, through which the head of anexcentric screw 31 pro- jetcs. The arcuate periphery of thetool 25 and the facing,arcuate wall 32 of thecavity 26 are provided withnotches 33 and 34 respectively, which make it possible to set thetools 25 as according to the following. - If the
lock screw 29 is loosened, thetool 25 can be swung about itsexcentric screw head 31, so that the angle of theedge 27 to thecutter spindle 9 can be changed. The setting can be done with a screwdriver which is inserted into a suitable pair of notches 33/34 and turned. The outer tip of thetool 25 can be set with the aid of theexcentric screw 31 so that it is in the end plane of thecutter 16 or at a desired distance therefrom, for example if themain tool 17 extends outside the end plane. - As can be seen from Fig. 3, the inside of the
bracket 12 is made with sufficient space next to the end of the cutter for theprojecting tools 25 if they are set at an obtuse angle to the main working plane 2 (the tools 17). - In front of the
cutter 16, theplane frame 1 is provided with achip discharge duct 35. For setting the cutting depth, the hand plane has a verticallyadjustable support plate 36 in front of thecutter 16. The vertical position of thesupport plate 36 is adjustable with aknob 37 which is arranged on the top of the forward portion of theframe 1, serving at the same time as a forward handle. - The planing is done by gripping the
handles support plate 36 in contact with the workpiece. Thecutter 16 shaves off the outer layer of the work piece down to the level of thebottom surface 2. At the right side of the hand plane, planing can be done right up to a wall or the like standing upright from the workpiece. With theknob 24, theplate 19 can be set at the desired angle for contact with the wall. This feature also enables the hand plane to be used for rabbeting with unlimited depth of groove. Furthermore, it is possible to place the hand plane with theplate 19 resting against the surface to be planed if it has locally projecting portions, for example. The plane can then be slid with theplate 19 against the workpiece, and the right-hand edges of theplaning tools 17 will work the surface like a milling cutter. In this type of work, and in rabbeting, it is an advantage that the ends of the planing tools only be in contact with the work surface during a very short portion of their arcuate movement close to thebottom plane 2. This prevents scratches and roughing of the workpiece as a result of inadvertent contact between the planing tools and the workpiece at other portions of their path of movement. - With the
lateral tools 25 in the end of the cutter, lateral walls can also be planed. Various forms of surfaces or grooves can be achieved by a suitable combination of angle and projection of thelateral tools 25, angle of thelateral support plate 19 and height of thesupport plate 36. Fig. 4 shows a setting with the edges of thelateral tools 25 parallel with the end of the cutter and thelateral support plate 19 at the smallest angle to the workingplane 2. With this setting, the hand plane can be used to plane dove-tail grooves. When thelateral support 19 is set at an angle of less than 90°, as shown in Fig. 4, the lateral walls can be only so high that the lateral wall extends up to theside 38 lying outside thelateral support 19. Thisside 38 lies at a distance b inside the side plane 18 (see also Fig. 3). - The
planing tools cutter 16 from the frame. If thecutter 16 should need to be removed, this is done simply by loosening the fastening screws for thebracket 12, and pulling thebracket 12 with thespindle 9 and thecutter 16 out of theframe 1, by virtue of the fact that theball bearing 10 can be pulled out of its seat in theframe 1. Thedrive belt 7 must then first be removed from the belt pulley'8, which is of smaller diameter than theball bearing 10 and thus can pass through theframe 1. Alternatively, thebelt pulley 8 can first be removed. - The axial position of the
cutter 16 is defined in relation to thebracket 12 and thus in relation to thelateral plane 18. This is achieved by thecutter 16 being axially fixed on thespindle 9 which is in turn held axially fixed by the bearing 11 with the aid of anintermediate ring 39 and alock ring 40 on opposite sides of the inner ring of theball bearing 11. Said bearing 11 is in turn held fixed in thebracket 12 by thecover 14. - For safety, the hand plane must also be equipped with hand protectors. For the sake of clarity, these have not been shown in the drawings.
- In the embodiment of the hand plane described above and shown in the drawings, the drive means of the cutter is placed at the thin end of the cutter. Alternatively, however, the cutter can be driven at its wider end. In this case, the cone angle should be larger to provide a sufficiently large lateral space for the belt pulley without having to increase the cutter diameter too much.
