Definitions

  • This invention relates to an attachment for a drive shaft of a drill or like rotary tool and relates particularly, but not exclusively, to such for use with an electric drill.
  • the present invention has been devised with the principal object of providing an attachment which will make the task of making the drill ready for drilling holes or for driving screws easier.
  • an attachment for a drive shaft of a drill or like rotary tool comprising two tool bit holding means, one being for connecting with the drive shaft and for holding one tool bit and the other being for holding the other tool bit, each of the tool bit holding means being releasably interconnectable with the tool bits in place, and so, in use, drive can be imparted from the one connected with the drive shaft, to the other, the interconnection being such that the appropriate one of the tool bit holding means can be fitted to or removed from the other depending on which tool bit is req-uired.
  • connection of the first tool bit holding means to the second tool bit holding means is such that the tool bits held thereby will be axially aligned.
  • the second tool bit holding means comprise a drill chuck.
  • there be releasable holding means comprising pin means on one of the tool bit holding means for locating in slot means in the other of the tool bit holding means and that the releasing of the interconnection is effected by axial twisting or rotation of one of the tool bit holding means relative to the other about the central axis of the drive shaft.
  • Figure 1 is an exploded isometric view of one preferred attachment means
  • FIG. 1 is a side view in assembled relationship and in part section of the attachment means shown in Figure 1;
  • Figure 3 is a side view similar to that in Figure 2 showing the first tool bit holding means spaced from the second tool bit holding means;
  • Figure 4 is a side view in part section showing a different embodiment
  • Figure 5 is an exploded side view in part section of the embodiment shown in Figure 4; and Figure 6 is an exploded isometric view of the embodiment shown in Figures 4 and 5.
  • an attachment device comprising a fir ⁇ t tool bit holding means 1 and a second tool bit hoi ,ing means 3.
  • the first tool bit holding means is fastened to a drill or like rotary tool 5 by removing the conventional chuck therefrom and by screwing the first tool bit holding means 1 onto the drive shaft 7.
  • the first tool bit holding means 1 is manufactured from a suitable material such as steel. It is generally circular in transverse cross section and has a central body part 9 with a rear circumferential flange 11.
  • the forward nose 13 is tapered and has a hexagonal bore 15 extending axially thereinto from the forward nose 13.
  • the hexagonal bore 15 is of a standard size to receive standard sized hexagonal work tools such as screw driver bits 17.
  • the central body part 9 has a radially outwardly extending pin 19 and three spring detent balls 21 circumferentially in line with the pin 19.
  • the spring detent balls 21 are urged by spring means (not shown) to a radially outermost position from the central body part 9.
  • a magnet (not shown) can be provided in the hexagonal bore 15 to magnetically hold the screw driver bit 17 in the hexagonal bore 15.
  • the second tool bit holding means 3 comprises a cup shaped body part 23 which is screw fitted to a conventional drill chuck 25.
  • the cup shaped body part 23 can be machined from a suitable material such as steel and arranged with a forward spigot 27 which is externally screw threaded so that the cup shaped body part 23 can be connected with the chuck 25.
  • Figure 2 clearly shows that the cup shaped body part 23 and the forward spigot 27 are hollow.
  • the body part 9 and the forward nose 13 and the screw driver bit 17 on the first tool bit holding means 1 are fitted within the hollow cup shaped body part 23 and into the hollow forward spigot 27 as shown by Figure 2.
  • An internal circumferential groove 29 is provided in the cup shaped body part 23 and positioned to align with the spring detent balls 21.
  • the spring detent means in the form of balls 21 engage in the circumferential groove 29 and assist in holding the second tool bit holding means 3 to the first tool bit holding means 1.
  • the pin 19 can pass along a slot 31 which has a longitudinally axially extending component and then a circumferentially axially extending component.
  • the second tool bit holding means 3 can be fitted to the first tool bit holding means by passing the pin 19 along the slot 31 and then rotating the first tool bit holding means 1 relative to the second tool bit holding means 3 so that the pin locates in the circumferentially extending portion of the slot 31. Accordingly, when a drill bit 33 is fastened to the chuck 25, the second tool bit holding means 3 can then be fastened or attached or connected with the first tool bit holding means 1. Thus, in this condition, the drill 5 can be made ready to drill a hole with a drill bit 33.
  • the second tool bit holding means 3 can be released from the first tool bit holding means 1 by axial rotation of the first tool bit holding means 1 relative to the second tool bit holding means 3 so the pin 19 retraces along the circumferentially extending component of the slot 31 and then by relatively moving the two tool bit holding means apart, thereby disengaging the spring detent balls 21 from the internal groove 29 and so the pin 19 then moves along the axially extending component of the slot 31.
  • the second tool bit holding means 3 can be reconnected with the first tool bit holding means 1 by reversing the above procedure.
  • the circumferential flange 11 on the first tool bit holding means 1 is provided to locate against the rear of the cup shaped body part 23 of the second tool holding means 3 and to be of the same external diameter as the cup shaped body part 23.
  • This arrangement provides for a neat and secure fastening of the first tool bit holding means 1 relative to the second tool bit holding means 3 and this coupled with the spring detent balls 21 assist in maintaining good axial alignment of the components. It is to be observed that the central longitudinal axis of the screw driver bit 17 is aligned with the central longitudinal axis of the drill bit 33.
  • the first tool bit holding means 1 comprises a central body part 41 which is provided with a circumferentially extending groove 43.
  • the groove 43 extends radially in from the circumferentially outermost surface to an inner region. It is noted that there is a rear bore 45 in which the drive shaft 7 of the drill 5 is screw threadably received. Thus, the groove 43 extends radially inwardly towards the bore 45.
  • the forward end of the first tool bit holding means 1 is provided with a hexagonal bore 15 in the same manner as in the previous embodiment.
  • the hexagonal bore 15 is of a size to receive conventional sized hexagonal tool bits such as screw driver bit 17.
  • a permanent magnet may also be provided in the bore 15 to magnetically hold the screw driver bit 17 or other tool in that bore.
  • the body part 41 has three openings 47 therein as will be explained hereinafter.
  • the openings 47 extend in a direction parallel with the longitudinal central axis of the central body part 41.
  • the second tool bit holding means 3 is also cup shaped with a cup shaped body part 49 with a forward spigot 51 (see Figure 4) which is externally screw threaded so it can screw threadably engage with the chuck 25.
  • the chuck 25 can be held secured and drive thereto effected with the cup shaped body part 49.
  • the cup shaped body part 49 has a central longitudinally extending bore 53 therein in which can be received the screw driver bit 17 when the second tool bit holding means 3 is fastened to the first tool bit holding means 1.
  • Three hexagonal drive bolts 55 are screw threaded into respective screw threaded bores 57 in the cup shaped body part 49 so that the heads 59 thereof extend rearwardly of the chuck 25.
  • the bolts 55 are equally spaced angularly around the central longitudinal axis of the body part 49.
  • the openings 47 in the first tool bit holding means 1 comprise three bores 61 (not clearly shown) of a diameter which will allow the heads 59 of the bolts 55 to pass therethrough.
  • Figure 5 shows only one of the bores 61.
  • the three bores 61 are equally spaced apart around the body part 49.
  • the bores 61 extend to further bores 63 of a diameter corresponding to the shaft diameters of the bolts 55.
  • the openings 47 are provided by two bores - bore 61 and bore 63 - which interconnect.
  • the second tool bit holding means 3 can be fastened to the first tool bit holding means 1 by passing the heads 59 of the bolts 55 through the larger diameter bores 61 and so that the heads 59 pass into the groove 43.
  • the width of the groove 43 is marginally greater than the depth of the heads 59 of the bolts 55.
  • the first tool bit holding means 1 can be angularly rotated relative to the second tool bit holding means 3 so that the shafts of the bolts 55 rotate in the openings 47 to locate in the smaller diameter bores 63.
  • the rear face of the second tool bit holding means 3 is provided with an internal chamfer 65 and the forward edge of the body part 49 of the first tool bit holding means 1 is provided with an external chamfer 67.
  • the two chamfers 65 and 67 are complementary. Accordingly, by appropriate adjustment of the bolts 55, by screwing them into or out of the body part 49, it is possible to tightly mate the chamfers 65 and 67 to provide good secure interconnection of the first tool bit holding means 1 with the second tool bit holding means 3.
  • a hexagonal key can be passed into the openings 47 through the rear of the first tool bit holding means 1 prior to connection of the first tool bit holding means 1 to the drive shaft 7 of the drill 5.
  • the heads 59 of the bolts 55 can be used to tightly urge the two chamfers 65 and 67 into close mating relationship.
