Abstract
A multiple bit screwdriver employs a breach loading magazine to store a plurality of bits. The magazine is enclosed inside the hollow handle of the screwdriver and is extracted along the axis of the screwdriver when the end-cap of the handle is pulled. The bits are stored in the magazine and are located about the circumference of the magazine tube that reciprocates relative to the screwdriver. When the magazine is fully extracted, the bits are easily viewed and may be individually removed from or replaced in the clips applying a simple radial force.

CARTRID~E TYPE SCREWDRIVER
INTRODUCTION
This invention relatas to a multiple bit tool, and, more particularly, to a multiple bit tool such as a screwdriver.
BACKGROUND OF THE lNv~NllON
The use and existence of multiple bit tools are well known. Generally and in the case o~ a s~L~ iver used manually, the bits are st~red in the handle o~ the screwdriver. To retrieve a bit, the user removes the end-cap of the handle to expose the bits. One difficulty with such tools is that users have difficulty deteL in;n~
the appropriate bit without its removal. Hence, all of ' -the bits are usually emptied from the handle. ;~
Various ~ch~n;~rc have been devised to select individual bits. In U.S. Patent 4,463,788 to Corona et ~ ;~
al, a mechanism includes a rotatable disk at the anterior end of the handle in which a slot acts to guide one bit at a time from the storage chamberl or maga~ine, into the chuck.
In U.S. Patent 4,572,038 to Graham, a mechanism ~' is described in which the bits are stored in a forward magazine which rotates about a rear retractable driving shaft in order to individually engage the bits stored in the magazine.
In U.S. Patent 3,753,455 to Butler, the bits can ; '~;
be gravity fed from the storage chamber directly into the '~
chuck.

To attach the bit storage magazine 20 (Figure 5), second barrel sha~t 21 is placed over first stationary shaft ll and the magazine 20 is completely inserted into the hollow handle 12 by sliding along the circumference of the first shaft ll. With the magazine 20 in this fully inserted position within handle 12, the end portion of first stationary shaft 11 is accessible through the end of second barrel shaft 21. Retaining ring 30 is inserted into second barrel shaft 21 such that opening 32 in retaining ring 30 is slipped over the end of first ;
stationary shaft 11 until it i5 locked in place by the action of the teeth 17. Magazine 20 is then extracted from hollow handle 12 while ret~;nin~ ring 30 remains attached to first stationary shaft 11 while, as earlier ~ ~
described, spring clip 33 produces friction against the ; ~ -inside of second barrel shaft 21. The end of se¢ond barrel shaft 21 is then inserted ililtO the opening 40 of end-cap 13 and is bonded in place chemically or otherwise.
A pocket is thus formed between the second barrel shaft bevel 23 and the end-cap 13 which accepts the expansion of the spring clip 33 in its locked position.
OPERATION ~ ~;
In operation, the magazine 20 is extracted from within the hollow handle 12 by pulling the end-cap 13.
The second barrel shaft 21 travels along first statîonary sha~t 11, guided by the narrow diameter restriction or ;
r., "' ",:.,~,: ..:';'~r ~
2~2~
collar 22 at its anterior end and by the ~riction caused by spring clip 33. The magazine 20 is extracted until the narrow diameter restriction 22 in second barrel shaft 21 comes into contact with ~he anterior end of the ret~;nin~
ring 30.
In the extracted position, the plurality of pairs of fins 24 and their retained tool bits (not illustrated) are fully exposed to the user. The user may inspect the bits and select the desired one by rotating magazine 20 and applying an outward radial force to unclip -~
the bit from the fins 24. A bit no longer needed can be placed between an unused pair of fins 24 by applying an inward radial force.
The magazine 20 is then reinserted into the hollow handle 12 by pushing on end-cap 13. When the magazine 20 is within the handle 12, the spring clip 33 -will have travelled into the pocket formed between the 20 second barrel shaft bevel 23 and the end-cap orifice 40 so ~-~
as to maintain the end-cap 13 in it:s closed position. The spring clip 33 will expand within t:he pocket and lock the magazine ~0 into the closed position. -A further feature of the invention allows the end-cap 13 to be rotatable about stationary shaft 11 and relative to handle 12 when the magazine 20 is in its closed position. This me~h~n;! allows the user to apply a driving or axial ~orce with one hand and a torque to the tool with the other. To apply the driving force into the workpiece, the user places one hand on the end-cap 13 and applies a force along the axis of the tool. The torque is applied by the user grasping the screwdriver handle 12 and rotating it about the end-cap 13. Alternatively, the bearing 50 may be held and the handle 12 rotated so as to rotate the tool and bit relative to bearing 50 20~27~
While a specific embodiment of the invention has been disclosed, many modifications may readily occur to those skilled in the art to which the invention relates. :~:
Accordingly, the embodiment should be taken as illustrative of the invention only and not as limiting its scope as defined in accordance with the accompanying claims.
