  • Fig. 2 is a front elevation of the drill guide of Fig. 1;
  • Fig. 3 is a plan view of the driJ1 guide of Fig. 1;
  • Fig. 4 is an underside view of the drill guide foot means of Fig. 1;
  • Fig. 5 is a view of the foot of Fig. 4 from above.
  • a drill guide comprised of a work engaging foot means 10 mounted upon an extensible mounting means 11 attached to drill guide support means 12.
  • the drill guide's work engaging foot means shown in Figs. 1 and 2 may comprise a plate means 26 attached to the extensible mounting means 11 which may be two rods 16 and 15 inserted into holed formed therein.
  • the plate 26 provides a workpiece engaging face 13.
  • the plate means 26 may carry a groove 14 which serves to locate the foot upon small round pipes to ensure their accurate drilling.
  • Various forms of the plate means 26 may be provided to enable a variety of work engaging surfaces for non-slip properties on smooth materials such as sharp projections to bite into and locate the foot on vertical wooden surfaces, or rubberised non-slip surfaces for smooth metallic surfaces.
  • the work engaging foot means 10 is seen from beneath in Fig. 4 and above in Fig. 5 and its shape may comprise an open, horseshoe shape as illustrated to enable ready insertion and removal of drill bits whilst the drill guide remains attached to its hand drill.
  • 15 and 16 indicate the location of the two rods 15 and 16 of the extensible mounting means 11.
  • Figs. 1 and 2 show the layout of the mechanisms which may form the extensible mounting means 11.
  • the extensible mounting means 11 may be constructed upon two rods 15 and 16 carrying the workpiece engaging foot means 10 at one end thereof and the drill guide support means 12 at a position towards the other end.
  • the support means 12 may be slidably mounted upon the rods 15 and 16 and held at a set position by end 24.
  • the position of the support means 12 may be adjustable along the length of the rods to accomodate various drill ' lengths, etc.
  • Rod 16 may be marked with a scale (not shown) whereby the depth to which a drill bit has penetrated may be measured off at a suitable reference point.
  • an end stop 19 may be provided with a connection such as a winged screw 20 to affix it at a desired position to rod 16.
  • the rod 15 may be encircled by a spring 18 operative to push the foot means 10 away from the guide support means 12.
  • spring 18 is compressed as foot means 10 is pushed towards guide support 12.
  • the guide support means 12 is best seen in Figs. 2 and 3, and it may be fitted with a handle 30
  • CVPI for operation.
  • the handle 30 Opposite the handle 30 is a circular opening 40, split at 41 to enable the opening to clamp down upon a portable hand drill case just behind the chuck thereof.
  • the hole 40 is dimensioned to suit a chosen one of or a range of common power drills, and the drill is inserted and clamped with the chuck and a drill therein extending towards the foot 10. In this way the drill guide is carried upon the power drill and may be left permanently attached thereto.
  • spring 18 By pushing down on the power drill in use in the normal manner to contact the drill tip on a workpiece, spring 18 is compressed as the drill tip proceeds into the material .
  • the guide By leaving the drill guide attached to a power drill, the guide, which may be rugged in construction, becomes a protective " device against drills being broken should the drill be dropped.
  • the action of the spring provides a retractive force on finishing of a drilled hole, whilst the guides action ensures straight positive drill tip action so that properly circular holes of required size are reliably formed in the thinnest of sheet materials.
  • a handle 61 mounted upon a shaft 60 inserted into hole 62 may be provided as an attachment to foot means 10.
  • an operation stop 24 may be adjustable in position along rod 16 to lock the support means 12 between it and stop 19, locked by wing nuts 22 and 20 respectively, so as to hold the foot steady relative to the routing tool mounted in the portable drill. Handle 61 is then grasped to draw the tool across the surface.
  • an edge guide plate 65 mounted on slidable rod 66 passed through hole 67 ⁇ see Fig. 1) in foot 10 may be provided.
  • This plate may be locked by a suitable locking screw such as is commonly done with a grub screw.
  • plate 65 in Fig. 1 need only be turned down to engage over a workpiece edge and be locked in place to function as a guiding means.
  • the handle 61 becomes a stand for the front end of a drill in its resting position on a bench to hold the chuck up above the bench so that tools such as grinding wheels may be inserted therein.
  • the wheel With the stops 24 and 19 on rod 16 suitably locked against support means 12 to locate the foot relative to a grinding wheel in the chuck of a drill to which the guide is mounted, the wheel may be used to sharpen drill bits, blades, etc.
  • the edges of the foot 10 or the guide 65 may be employed as rests for tools being sharpened.
  • the guide 65 may be rotated into a suitable position for that purpose, and in Fig. 5 is shown a niche 68 in which drills may be rested to engage with a grinding wheel (not shown) .
  • the handle 61 is shown upon a rod 60 angled upwardly at an angle of 45°. Where a hole to be drilled must enter a workpiece at this angle, the guide may be tilted over to rest on the handle so as to be guided at the right entry angle.
  • Various rods with handles might be supplied for interchangeable insertion into the foot to enable a range of entry angles by preselection and use of an appropriately angled handle.
  • the edge guide 65 may be disposed outwardly of the foot on its rod 66 to provide broad workpiece engagement when required. As seen in Fig. 2, the edge guide 65 need only be prov ⁇ ided with a depth matching that of the foot in one of the guide's orientations so that it may be slid to an outwardly disposed position so as to become an additional bracing surface during drilling.
  • rod 15 is provided with a winged nut 23 at its end so that springs 17 and 18 which may each comprise a number of springs butted end to end, may be interchanged by removal of end stop 24, sliding of the rods from support 12, to release springs 18. In this way, by interchanging springs, the support means 12 may be biassed to a particular pos- ition relative to foot 10.
  • the foot By reversing the position of the guide upon the drill so that the foot extends back behind the drill, the foot can be employed as a shoulder rest for bracing of the drill in heavy duty applications which require it.
  • the stops 24 and 19 are employed.
  • the handle 30 may be a plastic moulding, hollowed to serve as a storage point for drill bits with a suitable moulded closure in the end * to enable safe storage and ready access.

Abstract

Guide pour perceuse avec base d'engagement (26) d'une pièce à usiner montée avec un mouvement coulissant suivant une direction parallèle à l'axe de perçage d'une perceuse portative sur laquelle le guide (12) peut être monté, ayant un collier d'engagement (12) de la perceuse à l'aide duquel le guide est fixé à la perceuse en un point situé juste derrière le mandrin. La base d'engagement (26) de la pièce à usiner est sollicité de manière résiliente (18) dans le sens opposé au collier (12) de manière à créer une force de retrait à la fin du perçage, et la base d'engagement de la pièce à usiner (26) encercle un foret monté dans la perceuse lorsque cette base est appliquée à une perceuse, un côté étant ouvert pour permettre d'adapter aisément des forets dans le mandrin.
