Specification of Letters Patent.
Patented June 9, 1908.
Application filed September 16, 1907. Serial No. 393,090.
T 0 all whom it may concern:
Be it known that I, /l' mssrnn L. MARBLE,- a citizen of the United States, residing at Gladstone, in the county of Delta and State of Michigan, have invented new and useful 1mprovements in Compound Tools, of which the following is a specification.
This invention relates to compound tools, and its object is to provide a convenient pocket tool carrying one or a plurality of implements, each capable of being quickly adjusted for use, or shut within a protecting handle, as desired the entire instrument be ing simple in construction, and cheap to make. The implem ents may be screwdrivers, punches, nailsets, or'any other tool desired, and may be of different kinds, or all of one kind in different sizes, as may best suit the requirements of the user.
The handle comprises two parallel similar plates, one or both being of resilient metal, such as steel, united by a central screw or rivet. At one or both ends is a transverse pivot pin on which the implement or implements can be pivoted, so as to be capable of shutting into the handle or opening out for use. In the hub of each implement is a recess, preferably a transverse groove, with which cooperates a projection or rib on the handle, so that when the implement is in its open or closed positions, the projection springs into the recess and holds the implement yieldingly against movement in either direction. In order to lock it positively and prevent it from accidentally closing or opening, a locking device is provided: preferably a slide which enters beneath the head of the pivot pin and thus prevents the resilient side plates of the handle from separating which they must do to permit the projection to lift out of the recess in the act of opening or closing the implement.
In the accompanying drawing :-Figure 1 is a side elevation of a compound tool embodying my invention. Fig. 2 is an edge view of the same. Fig. 3.is a longitudinal section, and Fig. 4 is a perspective view of an implement.
The tool which I have chosen to illustrate contains four implements-all screwdrivers, of different sizes, 1, 2, 3, 4. They are pivoted in pairs at the ends of a handle, composed of side plates 5, 6 of resilient metal, such as steel. These plates are properly spaced apart by a space block 7, and are united by a passing through said screw 8, preferably of the length block at a point about midway of the handle.
At each end of the handle is a transverse pivot pin 9, 10, fixed in one plate and passing freely through a hole in the other plate. In the drawing, the two pins are shown as fixed respectively in the two plates, but it is evident that they might both be fixed in the same plate, if desired. On these pins the implements are pivoted, two on each pin, side by side. The hub of each implement has a pivot hole 11 for the pin, and a pair of grooves l2, l3 crossing said hole at right angles. The side plates of the handle have internal ribs 14 intersecting the axes of the pivot pins. The construction is such that the plates constantly clamp the hubs of the implements with a yielding pressure, which forces the ribs into the grooves when they register. The grooves are so located that the implements will be retained in their open or closed positions by the interlocking of the ribs with the transverse grooves 12; while they will be held in a position at right angles with the handle when the ribs interlock the longitudinal grooves 13.
The act of changing an implement from one position to another causes the side plates of the handle to separate, in order to permit the rib or other projection to ride up out of the groove or other recess. It is, however, highly desirable to prevent the implement from turning when in use, since otherwise it might shut accidentally and wound the -lingers of the operator, or injure the work or the tool itself. I provide, therefore, at each end of the handle, a locking device to hold the tool rigidly in any position in which it may be retained by the interlocking of the rib and a groove. This locking device is preferably some means for preventing the separation of the side plates and the consequent disengagement of the rib and groove. I prefer to effect this by extending the free end of each pivot pin beyond the surface of the side plate through which it passes, and to provide it with a head 15 under which a locking plate 16 can be thrust. This plate is preferably a flat strip of metal having a slot 17 through which passes a rivet 18 by means of which. the strip is secured to the side plate, and by which it is guided in its movements. The locking plate shown operates as a sliding bolt. At one end of the slide is preferably a thumb piece 19, and its other end is slotted or forked at 20 to pass on each side of the pivot pin underthe head 15.. In this position the slide fills the space between the head and the plate, and thus effectually prevents the side plates from separating. It can be easily slid to and fro by the thumb of the hand that is grasping the tool, leaving the operators other hand free to hold the work or perform other duties.
or convenience in opening the implements, each one has a projecting heel 21, and these are preferably curved in opposite directions to facilitate their manipulation. When one implement is in use, the two at the op 0- site end of the tool may be set at right ang es to the handle, as shown in Fig. l, to serve as a cross handle and aiford a better grasp or give greater torsion.
The parts may be stamped out of sheet steel, the grooves and ribs being formed at the same time. This conduces to cheapness of cost, and simplicity and durability of construction.
Having thus described my invention, what 2 I claim is A compound tool comprising a handle consisting of two resilient side lates, a space block between them at the micl dle, pivot pins each fixed near one end of one plate and eX- 3 tending through the other and provided with a head, two or more implements pivoted on each pin and provided with heels extending beyond the handle and curved toward opposite sides thereof, interlocking ribs and 3 grooves on the lates and im lements, forked slides on the p ates adapte to engage with the heads on the pins, and provided with longitudinal slots, and rivets fixed in said side plates and engaging with said slots. 4
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
