UNTTED STATES PATENT OFFICE.
CHARLES E. STONE, OF BOSTON, MASSACHUSETTS, ASSIGNOR TO E. H. COBSON, OF
- BOSTON, MASSACHUSETTS.
WRENCH.
Specification of Letters Patent.
Patented Aug. 22, 1911.
To all whom it may concern:
Be it known that I, CHARLES E. STONE, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in WVrenches, and do hereby declare that the following is a full, clear, and exactdescription of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of refer ence marked thereon.
The object of my invention is to provide a wrench or like tool which is capable of use for a great variety of purposes, but will nevertheless, satisfactorily perform each of the functions for which it is adapted and at the same time be of simple and inexpensive construction, and to this end my invention consists in the tool constructed substantially as hereinafter specified and claimed.
In the accompanying drawingFigure 1 is a perspective view of a tool embodying my invention; and Fig. 2 a longitudinal section thereof.
In its fundamental or basic structure my tool is in the form of a pair of pliers, that is to say it comprises two levers or members 10 and 11, respectively, pivotally connected together, each member having a handle and at one end a jaw, the jaw 12 of the member 10 projecting at right angles thereto and the jaw 13 of the member 11 projecting at right angles thereto, the two jaws having their gripping faces preferably roughened. The member 10 is slotted or formed with a chamber 14 and through such chamber passes the jaw and contiguous portion of the member 11, so that the jaw 13 thereof and the handle portion thereof are on opposite sides of the member 10. It will be evident that the two jaws may be placed nearer to or farther from each other by reason of the sliding connection thus provided between the two jaws to suit the size of the object to be grasped or caught between the two jaws. A pivotal connection is formed between the two members 10 and 11 by a transverse pivot pin 15 which passes through the portion of the member 10 lying in the chamber 14, and has its opposite ends respectively fitted in longitudinally extending parallel'slots 16 in the opposite side walls of the chamber 14, said slots being provided for the hereinbefore described movement of the two jaws toward and from each other the necessary bearing for the pivotal movement of the two parts being furnished by the contact of the opposite walls of each slot and the diametrically opposite sides of the pivot pin 15. It is, of course, important to firmly support or secure the slidable pivot pin fulcrum at the desired position of adjustment. For this purpose I employ a supporting latch bar 17, which at one end is pivotally connected to the pivot pin 15 and thence extends rearward being accommodated in a groove or channel 18 in the inner side of the member 10 and its rear end being provided with a lug or projection 19 adapted to engage any one of a series of notches or holes 20 in the inner side of said member 10, the bar being thereby held against longitudinal movement and accordingly holding the pivot or fulcrum pin 15 from such movement as would change the adjustment of the jaws relative to each other.
The rear end'of the bar 17 is upturned slightly to enable it to be readily caught to lift its holding lug or projection out of a retaining hole or notch. Said bar is pre vented from accidental displacement by contact therewith of the free end of a spring 21 whose other end is fastened to the movable member 11, said spring serving the double function of holding the bar in looking position and swinging the movable member 11 on its pivot or fulcrum to open the jaws. It will be seen by shifting the pivot pin 15 along with the member 11, the leverage of the movable member will always be the same because there is no change of position of the pivot pin with reference to said movable member.
The jaws 12 and 13 are useful for a great variety of purposes, such as pliers, a nut wrench, a pipe wrench, a nut cracker and for lifting dishes, pans or other articles. To render the tool further useful the member 10 is provided with a transversely extending hole 22 so that wire inserted therein may be cut by a cotiperating surface on the movable member 11 and at one end the member 10 is formed into a screw driver 23 and at the other end is provided with a can opener 24, while the free end of the member 11 is provided with a tack puller 25.
It will be understood that though I have enumerated uses to which my tool may be parture from the scope of my invention as;
expressed in the claims. Having thus described my invention what I claim is I 1. In a tool, the combination of a member having a handle portion and a jaw extending at right angles to the handle portion, and having a chamber, a second member having a handle portion and a jaw at right angles thereto with a portion in the chamber of the other member, a pivot pin passing through said portion in said chamber with opposite ends slidable in slots in the opposite walls of said chamber, a bar pivotally connected at one end to said pivot pin whereby said bar is pivotally connected to the member having the portion lying within the chamber of the chambered member, said pin thus forming the fulcrum for said member, the sliding connection between it and the other member and the fulcrum of said bar, and a proj ection on said bar adapted to engage in one of a series of holes or notches in an inner side of said slotted and chambered member.
2. In a tool, the combination of a member having a handle portion and a jaw extending at right angles to the handle portion, and having a chamber, a second member having a handle portion and a jaw at right angles thereto with a portion in the chamber, a pivot pin passing through said portion in said chamber with opposite ends slidable in slots in the opposite walls of said chamber, a bar pivotally connected at one end to said pivot pin and thence extending rear ward, said bar having a projection, a series of holes or notches to cooperate with said projection, and a spring interposed between said bar and the handle portion ofthe pivotally mounted aw.
In testimony whereof I affiX my signature in presence of two witnesses. 7
