  • a magnet 128 above the chuck l16 In situations where steel bits are used, it may be desirable to locate a magnet 128 above the chuck l16.
  • the purpose of the magnet is to assist insertion of the bit end into the chuck 116 by attracting the bit upwardly from the collar 92 into the chuck 116.
  • the use of the magnet 128 above the chuck retains the bit end in the chuck during normal usage of the screwdriver. This avoids the need for locking the bit end in the chuck.
  • the bits 20 are stored in the magazine of channels 28 of the handle 12.
  • the cap 14 is secured to the upper portion 15 of the handle.
  • a detent device 36 is located in the recess 130 of the handle.
  • An opening is cut through the wall portion 132 of the handle so that the respective arms 134 of the detent cage 36, as shown in Figure 9, extend through the formed opening 136 into the channel 28.
  • Each finger 134 of the detent has rounded edges 137 to facilitate camming inwardly of the respective detent finger by the lugs when the bit 20 is either inserted or retracted from the magazine.
  • the bit 20 is retained in the magazine yet provides for releasable withdrawal of the bit from the magazine with the bit in the stored position when the bit selector cup 18 is rotated to select that particular bit.
  • the lug 26 projects to the extent shown to allow the user to manually engage the lug 26 and push it downwardly depressing the detent finger 134 inwardly as shown by arrow 138 of Figure 9.
  • the selected bit 20 has been withdrawn from the channel 28 where the groove 34, as it engages lug 32, aligns the other lug 26 with the slot 58 of the depending finger 65.
  • the lug 26 located in the slot 58, automatic alignment of lug 32 is provided with the groove 108 of the collar 92.
  • a ring 140 is provided about the shaft 24 of each bit. The ring 140 has an external diameter larger than the width of the elongate slot 84 in the bit selector cup, so that by interfering with the lugs 26 and 32, ring 140 precludes withdrawal and thereby retains the selected bit end in the selector cup.
  • the ring 140 is circular in shape to assist in sliding of the ring 140 up and down the bit shaft to avoid jamming of the bit shaft within the ring.
  • the ring 140 may be shaped like an annular cylindrical ring.
  • a groove 141 is provided in the base of the selector cup. This groove receives the bit tips and the shoulders of the groove maintain the ring 140 on the bit shaft in the manner described in more detail in United States patent 4,463,788.
  • the collar 92 has a flange portion 142 beneath the collar ring 106.
  • the support wall 96 for the collar includes an upper face 144, as shown in Figure 5.
  • the length of the collar wall 92 is less than the height of wall 96.
  • a space 146 is defined between the insert and the interior wall 82 of the bit selector cup. This space receives the ring 140 as the bit end is moved laterally, radially inwardly of the bit selector cup to within the collar 92 through the lateral opening 104 of the collar insert.
  • the new position for the bit shaft 24 is shown in Figure 6 with the ring 140 located in the space 146.
  • the chuck 116 has a bore portion 118 which is sized to provide operative faces 120 which engage the operative faces 123 of the bit end 19.
  • the operative face arrangement 123 for the bit end consists of a star-shaped arrangement, the section of which is shown in the chuck bore 118 of Figure 14.
  • the chuck bore 118 has nine operative internal face portions 120 in the form of pointed recesses.
  • the lugs 26 and 32 thereby align the corresponding points on the bit end for direct vertical insertion into the chuck 116.
  • the number of operative faces on the bit end will always be equal to or a multiple of the number of channels in the handle bit magazine.
  • the opening 97 is of a width between opening edges 97a and 97b, as shown in Figure 15, less than the overall diametrical width of the lug extremities.
  • the lugs will interfere with the opening edges 97a and/or 97b to encourage the user to turn the bit end so as to commence alignment of one of the lugs with the groove 108 in the collar portion.
  • the collar 92 is provided at its rear face 150 with a magnet 152 which is integrally molded with the wall portion 154 of the collar 92.
  • the magnet 152 is provided with a groove 156 which functions in the same manner as groove 108 in the collar of Figure 13.
  • the poles of the magnet 152 are as indicated.
  • the bit end can also be magnetized with the polarity shown. By natural attraction of the north pole of magnet 152 to the south pole of the magnetic bit end 19, lug 32 is naturally aligned with groove 156 of the collar 92. In this manner, another form of aligning the lug of the bit end with the collar groove is provided.
  • the bit selector cup 18 may be rotated something less than 180° to thereby misalign the grooves 108 and 110 with the lugs 26 and 32 of the bit end, so that the lugs are captured in the space 125 by the upper surface 111 of the collar ring 106.
  • the arrow 48 may be aligned with the nearest dot 51 to accomplish lacking.
  • the selector cup is rotated back to align the arrow 48 of ⁇ he selector cup with the marking 46 indicating the particular bit extracted. This will realign the slots 108, 110 with the lugs and permit withdrawal of the bit so that it may be transferred laterally and returned to within the chamber of the bit magazine for storage in the manner shown in Figure 9.
  • a rotatable disc 160 is mounted in the bit selector cup 18.
  • the disc at its periphery includes a circumferential ridge 162 which is received in a groove 164 of the bit selector cup.
  • the disc 160 is provided with a handle portion 166 to facilitate for manual rotation of the disc 160 relative to the bit selector cup slot 84.
  • rotation of the slot portion 168 of the disc commences closing off of the slot 84 in the cup.
  • the end 170 of the slot 168 captures one side of the bit while the inner portion of slot 84 captures the other side of the bit to grasp this lower portion of the bit shaft 24 to stabilize it and resist lateral forces.
  • FIG. 6 An alternative chuck arrangement is shown in Figures 6, 7 and 8 which eliminates the need of ring 140 to retain the selected bit in the selector cup.
  • An enlarged nonagonal-shaped head 172 is provided at the bit end 19. The lugs 26 and 32 of the bit shown in Figure 2 are removed. The enlarged head 172 has a width approximating that of the width defined by the extremity of the lugs 26 and 32 of the bit of Figure 2.
  • the chuck 116 has a bore which is of a size sufficient to receive the enlarged head 172. The bore of the chuck 116 approximates the size of the space 125 of Figure 5.
  • the enlarged head 172 is of a width greater than the width of the groove 84 of the bit selector cup.
  • the collar 92 has a modified interior surface to receive the nonagonal shape of the enlarged head 172.
  • the upper portion of the collar 92 is enlarged to permit upward insertion of the enlarged head 172 into the chuck 116.
  • the overall length of the screwdriver may be reduced due to the elimination of the space 125 of the handle configuration of Figure 5 and a much thinner bottom wall for the bit selector cup where space 141 of the bit selector cup of Figure 4 is no longer required.
  • the shape of the nonagon is shown in more detail in Figure 8 where the chuck bore 174 has the nine equal sided faces to receive the corresponding faces 172 of the bit end 19.
  • the number of sides is equal to the number of chambers 28 in the screwdriver handle. It is appreciated that ready alignment of the bit end with the chuck can be achieved with a multiple of the number of chambers in the handle. For example, instead of nine operative faces, eighteen faces could be provided in the chuck bore 174 and on the bit end 19.
  • a depending flange portion 56 on the lower end of the handle which is slotted, enables one to reduce the overall diameter of the handle by permitting withdrawal of the bit end from the channel through passage of the respective lug of the bit end the slot in the depending flange.
  • comfort in use of the screwdriver is provided.
  • Another modification, which can be made to the handle is to provide about the lower handle periphery 30, a circumferential depression to accommodate the thumb during use.
  • the groove in the collar may be provided the length of the insert without any difficulty in molding and manufacturing the part.
  • the selection cup interior may be readily injection molded and then the insert simply placed into the cup.
  • Such slots in the handle depending flange also facilitate snap fitting of the bit selector cup onto the handle to thereby accommodate tolerances in manufacturing of the cup perimeter and the handle perimeter.
