Our invention relatesto' a hand tool whereby a mechanic; in the form of a single unit; is provideci with a plurality of extensible: bits of different' sizes and of desired cross-sectional con:- fi'guration adaptable toscrew-head's or' caps of the various'typ'e at present employed. Due to theuse of the different types of hollow headed screws-a mechanic is compelled'to provide himseitf withthe different types of wremih-bits-as for example, the A11en--the- Phl1lips-the Bristol-'-ancf their various sizes, so thatconsiderable time is fre'quently' required in asearch for a bit of-therequired configuration and size.
@ur invention contemplatesa unit or case of convenient size formed to slidably enclose a pluraliw' of different sized bits adapted to be separately protruded or extended through separate openings spaced apart about theperimeter of the case or shell; the case or shell involving means whereby the selected bit may heloclied in its extended position while the other bits are locked within the shell orcase against movement, or whereby all of the bits may be simultaneously locked in their retracted positions within the shell or'case.
The objects and advantages of our invention will be readily comprehended from the following detailed description of the accompanying drawing wherein- Figure 1 is a plan view oftheface' orupper side of our improved tool, showing-one of the wrench bitsiin extended position.
Figure 2 is a similar view of the rear or bottom side;

Figures '7, 8 and 9 are perspective views of some of" the types of wrench bits;" while Figure 10 is a perspective view of ascrew-driver" bit.
Qur improved device or' tool preferably is of a symmetrical and convenient size which may be-easily manipulated and carried in the pocket of the user and the groups of preselected types of-bitsmaintained in their assembled or grouped relation.
In: the particular exemplific'ation of the invention; the sheil i or: case preferably is of; annular formwconsisting preferably of two halves orrsuhstantially similar forged sections to, Hi;- of" suffeci'ent' thickness: adapted to: be arranged in faceto-face contactand secured together in suitable manner as for example by a plurality of countersunk hollow headed screws I 1.
In: the exemplification, each section is pro:- vided with a circular cavity lfitintermediate outer perimeter of the section and the central hub portion 1' 9 7 of the: shell; the: combined 'caviities I8; I 8 being adapted to slidably receive the various bits- 20, which eithermay be of thereon figuratio'n shown in Figures Z (and: in the: first sixrfiguresof the drawing)"; or the configuration of wrench bits 2'1, 2'1 shown in Figuresz'i and 9-01" the configuration of screw-driver bit 22:, shown 10;: the. respective bitsofi'axun-it 'being' oi different sizes as indicated: in Figures 1 3 and 5; or. any: suitable combinationofi hits may be: employed.
The outer annular walls or perimeterslof the two sections: [5, l5: at suitable.- circumiaerentially spaced; points are provided: with similar: openin'gs: 23 of. cross-sectional configuration, seelili'g ure 3, matching the cross section of. the respective bit. and to: allowitheabits to. slide in said open-- ings from their retracted position, shownati the left in Figure 4, to the extended; position shown attheleftiin Figure? The sections i5, i6 are; provided with apluzrality of circumferentiallyspaceds. radiali slots: '24 which. communicate with the chamber formedzby the: cavities: I8 and extendxfrom" the central huh portion IE tothe. innerends of the openings; 23 atitheouter-rimxof the device.
The inner ends of: the bits" are each: provided with attransverseiy disposed portion; or pin 25:, extending; beyond opposite sides of: thebits and of length sufficient to extendinto the radial: slots 24 in both. body sections; [:5 and; t6 and terminate atrthe: outer faces of thersections, as: shown: more clearly in Figure 4', where the; operators fingers can: engage the ends of the: pins to slide the selected-obit outwardly-= One: of the. case sections-,qnamely thetop or face. section 15, preferably is provided: withz'a-n annular" cavity or: countersunk portion 2:8", whose outer perimeter lies inwardly: ofrthe outer ends of the radial slotsl l namelya distance. removed from the outer ends of the-slots corresponding substantially to the diameter or thickness of the ends of" the pins 25 The annular cavity-"Z5 is provided with a flat faced ring 21', of width: less than the-length or the. radial slots 24, so asto leave the endsioffthel slots 24 uncovered for the reception of the ends of the bit-pins 25 when the bits are in retracted or extended position, as shown in Figure 6. The fiat faced ring or ring plate 21 is provided with a sectoral cut-out or removed section at 28, of size sufficient to completely uncover a single slot 24, as shown in Figure 6; the ring-plate 21 preferably having a slightly beveled perimeter to receive the overhanging lip or peened over metal 29, whereby the ring plate 21 is rotatively held in flat contact with and in the depression or cavity 26 in the face of the section l5. In order that the ring-plate 21 may be readily rotated in the cavity, it is shown provided with the outwardly upset finger-nail engagingportions Bil, 30, on opposite sides of the sectoral cut-away portion of the ring-plate.
As is apparent from the construction shown in Figure 1, movement of the bits is impossible when the sectoral cut-out 28. of the ring-plate 21 is brought intermediate adjacent slots 24; the in ner perimeter of the ring-plate 2'! being for-v ward of and in engagement with the bit-pins 25 when the bits are in retracted position.
When the user desires a certain bit he rotates the ring-plate 21 until the sectoral cut-away 28 registers with the selected bit and uncovers the pin slideway or radial slot, as shown at the left in Figure 6, thus allowing the pin 25 to be slid to the outer end of the radial slot and thereby cause the bit to be extended or protruded from the shell or case. The ring-plate is then shifted slightly across the radial groove so the outer perimeter of the ring-plate adjacent its ends (which preferably are slightly reduced in width) engages the protruding pin 25, thereby locking the bit in its extended operating position; rotation of the bit being accomplished by bodily twisting or turning the case which constitutes the shank or handle portion of the wrench or screwdriver.
We have shown and described what we believe to be a simple embodiment of the invention and combination of bits, but modificationsmay be possible without, however, departing from the spirit of our invention as defined in the appended claims.
What we claim is:
1. A tool of the character described comprising a pair of matching casing sections secured together in face-to-face relation and formed to provide a chamber therebetween, the face walls of the casing having radially disposed slots while the perimeter of the casing has a plurality of spaced openings aligned with the slots and communicating with the chamber; a plurality of radially disposed tool-bits slidably mounted in said chamber, with their inner ends having transversely disposed pins extending through the respective slots; and a split ring member rotatably mounted on one of the casing sections across the slots intermediate the ends thereof and in engagement with the pins of the toolbits whereby the tool-bits initially are locked against movement and the selected tool-bit permitted to be moved outwardly through its correlated opening when the split portion of said ring member is brought to register with the respective slot of said selected tool-bit.
