Application filed. December 15, 1931. Serial No. 581,182.-

This invention relates to a multiple action tool constructed to serve many 'uses and calculated to constitute anovel contribution to the field of invention to which it relates.

In carrying the inventive conception into practice, I have discovered how to construct two companion parts and connect said parts together mechanically to permit them to have conjoint relationship capable of serving in a multiplicity of ways so that the single tool or implement serves as a practical substitute for a number of independent tools such as would otherwise be required to fulfill the various uses to which this single implement may be appropriated.

The structural novelty is predicated upon a practical selection and formation of complementary parts especiallyrdesigned in configurationand shape to fulfill the requirements of a unitary tool of this class in a satisfactory manner.

In the drawings:

novel pair of pliers.

Figure 10 is a View similar to Figure 9 showing a further step in the operation of extracting a nail during which time the master part serves as a fulcrum and the subordinate part as a nail puller.

. The essential details of the invention are illustrated in Figures 1 to l inclusive while the remaining figures are employed to disclose the primary uses of the tool so as to enable the reader to better appreciate the diversified nature of the tool as a unit. 7

In Figure 3 the main or master, part of the tool is designated "by the numeral 11, and it comprises an elongated bar 12 preferably of rectangular cross section having a head 13 formed at one end. This head is disposed to permit it to serve as a hammer. The impact surface is indicated at 14 and the opposite. tapered curved end portion 15 is employed as a staple remover. Thus the head serves two functions and the bar 12constitutes a novel handle in both of these operations.

Along one longitudinal edge and intermediate the ends of the bar is an outstanding apertured lug-16 of segmental configuration.

a seat constituting one feature of a wire cutter and adjacent to the notch is a recess having serrations 18 forming an object gripping jaw. The lower end of the'handle bar in Figure 3 indicated at 19 constitutes the fulcrum and at this end I provide a pair of suitably shaped and proportioned claws 20. The secondary part 21of the tool is in the nature of a relatively short bar 22 generally employed as a lever and having one end portionbifurcated. The furcations are denoted by the numerals 23 and these straddle and intermediate portion of the bar 12 and terminate-in' apertured eyes 24 which embrace the lug 16 and are pivotally connected thereto by a pin 25. The fulcrum end 26 of this relatively short bar is formed with a pair of proportionately short claws 27 which are usable independent of the claws 20 and also in conjunction therewith.

The combined cross sectional area of the lever 22 and length of the claws 27 is approximately equal to the full length of the claws 20. Moreover the length of the part 21 is such as to permit the respective pairs of claws to swing into overlapping nested relationship as indicated in Figure 1.

The numeral 28 in Figure 4 represents a cutting tooth which cooperates with the notch 17 to form a wire cutter and the serrated notches 29 co-operate with the serrated surface 18 in forming a pair of jaws for gripping an object when the tool is employed as a pair of plyers, as shown for example in Figure 1.

It is evident therefore that by properly shaping and matching the two parts 11 and 21 they are allowed to co-operate in accurate mechanical relationship to serve a number of purposes. For example, the part 11 may be employed independently of the parts 21 as shown in Figure 9, as a claw or miniature crow-bar. This provides a satisfactory means for pulling nails and spikes.

Using the bar 11 as illustrated in Figure 9, the nail can be easily started on its way out and by employing the bar 11 as a fulcrum and resting it on the end 19 and bringing the part 21 into play as shown in Figure 10, said part 21 serves to continue the na1l extracting operation thus permitting re1at1vely long spikes to be extracted.

As seen in Figure 8, the device may be employed for drawing the ends of two wires30 and 31 together for fastening said ends. In this operation one end of the wire is provided with an eye 32 and the other end 33 is passed through the eye and twisted with a pair of plyers. At this time, it is ev dent that the parts 11 and 21' are used in con unction with each other, that is, the respect1ve claws 20 and 27 are engaged with the abutment or barbs 34; on the-wires. Moreover the bar 12 is utilized as a handle in this par ticular method of use.

Additional uses of the device are illustrated in Figures 5, 6 and 7 for fencewire work. Here the post is designated by the numeral 35 and the fencewire is indicated at 86, the same being provided with barbs or spurs 37. When using the tool for stretching the wire, the claw end 21 of the main part 11 is braced against the post 25 while the claws 27 of the smaller part 21 engage with the adjacent barb 37.

Using the part 11 as a lever and the hammerhead as a convenient handgrip the desired lengthwise pull may be exerted on the wire so that it may be drawn taut for fastening to the post.

The device may also be used in a slightly different manner as shown in Figure 6 at which time the fulcrum end 19 is placed directly against the post so as to allow the free end of the wire to be entirely wrapped around the post.

Then too, the device may be employed in the association shown in Figure 7 for wire stretching purposes. At this time the two parts 11 and 21 are brought together in the relationship illustrated in Figure 1 so that the claws 20 and 27 are overlapped somewhat in the nature of pliers, allowing the fencewire to be firmly gripped between the respective sets'of claws to cause the wire to bear directly against the post in order to tension and fasten the wire in a desired manner.

As before stated, the cutter 28 cooperates with the notch 17 in forming a suitable wire snipper or cutter at which time the wire is placed in the notch 17 and the parts 21 and 11 brought together in an obvious manner. Moreover, the roughened faces 18 and 29 serve as jaws when the device is used as pliers for tightening a nut or holding a bolt or some similar operation. Hence the foregoing and many other uses and advantages accompany a multiple acting simplified tool of the type herein disclosed and described.

It is thought from the foregoing descrip-- tion that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts provided that such changes fall within the scope of the appended claim.

I claim:

A tool of the class described comprising a straight bar having a claw forming part extending at substantially right angles from one end thereof, an ear formed on an intermediate part of the bar and extending in the same direction as the claw forming part and having a perforation therein, a forked and straight lever having the extremities of its tongues fitting over the ear and pivoted thereto, the free end of the lever having a claw forming part thereof which extends toward the claw forming part of the bar, the inner face of the claw forming part of the bar and the outer face of the claw forming part of the lever being correspondingly curved and the lever being'of a length to permit the curved outer face of the claw forming part of the lever to ride over the curved inner face of the claw forming part of the bar when the lever is moved to a position adjacent the bar, said prongs of the forked lever being of considerable length and spaced apart to receive a portion of the bar between them when the lever 1s swung toward the bar.

In testimony whereof I affix my signature.

GERBEN KEIZER.
