REY/551V Ffzp COMBINATION PLIERS AND WRENCH TOOL This invention relates generally to hand tools, and more particularly to a combination pliers and wrench.
A principle object of the present invention is to provide a combination pliers and wrench tool which has a slideable jaw member that may be interchangeable with a different type of jaw member in order to be suitable for various types of jobs.
Another object of the present invention is to provide a combination pliers and wrench tool which will deliver a maximum mechanical advantage to the fore-end of the tool when desired by the strategic placement of connecting pivot bolt and nut.
Other objects of the present invention are to provide a combination pliers and wrench tool which is simple in design, inexpensive to manufacture, rugged in construction, easy to use and efficient in operation.
These and other objects will be readily evident upon a study of the following spacification and the accompanying drawings wherein:
FIG. I is a side elevation view showing the invention with the jaws in opened apart position, the Figure illustrating in phantom lines an extremely closed position,
FIG. 2 is a rear view thereof,
FIG. 3 is a view taken on line 3-3 of FIG. 1,
FIG. 4 is a side elevation view of a modified form of sliding jaw member,
FIG. 5 is an end view of the device illustrated in FIG. 4,
FIG. 6 is a modified form of sliding jaw member shown in elevation,
FIG. 7 is an end view thereof, and
FIG. 8 is a cross-sectional view taken on the line 8-8 of FIG. 1.
Referring now to the drawings in detail, the reference numeral 10 represents a combination pliers and wrench tool according to the present invention wherein there are a pair of handle grip members 11 and 12, the handle grip member 11 having a fixed jaw 13. A bolt 14 and nut 15 secure the handle grip members 11 and 12 together, and a bolt 14 inserted through opening 14a of member 11 is slideable within an elongated slot 16 through handle grip member 12. A spring 17 is secured to bolt 14 and a pin 18 for allowing adjustment of the tool.
A cut away portion formed in the upper extremity of handle grip members 11 and 12 is provided with a rail 19' which engages moveable jaw 20 having a plurality of teeth 21 that are engageable with teeth 22 on the shoulder formed by the cut away portion 19 ofmember 12.
A horizontal groove 24 on each side of moveable jaw 20 engages with rails 19 in order that jaw 20 remains in alignment within the tool. A screw 25 provides for the securing of slideable jaw 20 within the tool.
It is to be noted that the handle grip member 12 of the tool is provided with a screwdriver portion 26 for engaging screw fasteners when desired.
Referring now to FIGS. 4 through 7, a modified jaw 27 and 28 may be used in place of the slideable jaw 20 if so desired.
In use, tool 10 is grasped by means of handle grip members 11 and 12, and the jaws 13 and 20 may be opened and closed by sliding handle members 11 and 12 which are slideable respective to each other by movement of bolt 14 along the diagonal slot 16.
The jaw 20 may be extended so to accommodate a larger size fastener or the like, and by extending it in a sliding motion along the tool whereby it may be secured to any desired position by means of the screw 25.
The horizontal groove 24 on each side of the movable jaw 20 is provided with a clearance for loosely receiving the rails 19' in order to permit a certain amount of vertical free play for the movable jaw in the recess jointly formed by the cut away portion 19 of the handle grip members 11 and 12, whereby the teeth 21 of the movable jaw maybe disengaged from the teeth 22 of the handle member 12 when the handles are slided relative to one another to position the bolt 14 at the end of the slot 16 against the bias of spring 17.
What I now claim is: 1. In a combination plyers and wrench tool, a pair of elongated handle grip members, a fixed jaw integral with one of said handle members, a first of said handle grip members having said integral jaw having an opening there through for receiving a bolt, a second of said handle grip members having a slot there to, said bolt securing said members together slideably relatively to one another, a removable jaw adjustably secured to said second handle grip member, said adjustable jaw including a bar having a row of teeth on one side thereof, each of said handle grip members having a cut away portion on one side thereof which jointly forms a recess for slideably receiving said bar.
2. The combination as set forth in claim 1, wherein said second handle grip member has a row of teeth within said recess for engagement with said row of teeth and said moveable jaw, a compression coil spring within said slot, one end of said spring bearing against one end of said slot and the other end of said spring bearing against a side of said bolt extending through said slot of said second handle grip member, and said slot extending at an angle respective to a plane of said rows of teeth of said second handle grip member and said slideable jaw member whereby sliding movement of said handle grip members respective to each other will cause said rows of teeth to disengage.
