Description

July 28, 1936.
N. RINK GRIPPER Filed April 20, 1934 INVENTOR ATTORNEY Patented July 28, 1936 UNITED STATES PATENT ()FFICE 4 Claims.
My invention relates broadly to grippers and/or wrenches and the like, and is designed more Specifically for the removal of can covers, fruit jar covers and such, but is also capable of being used as an eflicient pipe wrench and for similar purposes.
One of the objects of my invention is to provide a device of this character which may be cheaply manufactured and will serve as an effective tool for use in the household.
A further object of the invention is to provide a device of this general character which may be used as a pipe wrench or for other purposes.
In the accompanying drawing, Figure 1 is an edge view of the device; Figure 2 is a plan view; and Figure 3 is an end View of a detail part of the invention.
Upon referring to the drawing, A indicates the body portion or handle terminating at one end in a bifurcation composed of the jaws B and C, the jaw B being solid while the jaw C is provided with a slot E. Cooperating with the jaws B and C is a composite bar D. This composite bar D is made up of two members 4, having inwardly directed lugs 5, 6 and l. The lugs 1 are spacing lugs which serve to space the members 4 apart, and form the slot F at one end to accommodate the bar B and to form a recess between the lugs 5 and 5 for the slotted jaw C. The members 4 may be secured together in any suitable way, such as by passing a bolt or other securing means 8 through the lugs 1. The composite bar D is fitted over the bifurcation at the end of the handle A, with the jaw in the recess F and the slotted jaw C in the space between the lugs 5 and 6, and may be clamped in position by means of the bolt G and wing nut 9, the bolt G passing through the slot E into the jaw C.
The inner face of the jaw B and the inner faces of the members 4 of the bar D may be provided with serrations 2 and 3 respectively. These serrations 2 and 3 may be directed in such a manner as to permit the tool to be moved counter-clockwise or clockwise as desired.
In use, the cover, or pipe or the like, which it is desired to turn, is inserted in the bifurcation between the jaws B and C, as shown in dotted lines in Fig. 2. The bar D is then slid into contact with the cover or the like, and is then clamped in operative position by means of the 5 wing nut and bolt.
Upon moving the handle in a counter-clockwise direction it will be readily seen that the object clamped by the jaws and the composite bar D may be readily turned to effect removal. 10
What I claim is:
1. In a jar wrench and the like, a handle terminating at one end in a bifurcation, a cross bar associated with the bifurcation for engagement with an object inserted therein, and means for clamping the cross bar in operative relation.
2. In a device of the class described, a handle terminating at one end into a bifurcation composed of a solid jaw and a slotted jaw, a composite bar slidable over the bifurcated end for 2 contact with the object inserted in the bifurcation, and means cooperating with the slotted jaw for securing the composite bar in operative relation.
3. In a device of the class described, a handle 5 terminating in a bifurcation formed of a solid jaw and a slotted jaw, a cross bar formed of two complementary members spaced apart and adapted to be slid over the bifurcation for engagement with an object inserted therein, a bolt carried by the cross bar for engagement in the slot in the slotted jaw, and means cooperating with the bolt for clamping the cross bar in operative relation on the bifurcation.
4. In a device of the class described, a handle member terminating in a bifurcation having a solid jaw and a slotted jaw, a cross bar slidably mounted on the bifurcation, said cross bar comprising two complementary members, spacing lugs carried by the complementary members, means for securing said members together, and means cooperating with the slot of the slotted jaw member for clamping the cross bar in operative relation on the bifurcation.
