Application filed March 8, 1924. Serial No. 696,548.
This invention relates to a wrench especially adapted to be used with hexagonal nuts but which can, of course, be used on other nuts as well, and with serrations on the jaws,
6 can be used to turn round objects, such as pipes or rods, a single spring-operated pivoted jaw and a handle to which it is connected formin the complete wrench.
Another ob ect of the invention is to so 10 shape the pivoted jaw that it will, in conjunction with one side of the end of the handle to which it is connected fairly and evenly contact with four sides of a large hexagonal nut.
Another object of the invention is to so shape the end of the handle adjacent the movable jaw that it will properly contact with the smaller sizes of hexa onal nuts in such a way as to turn them rea ily and without danger of slippin and marring.
Another object of t e invention is toplace the pivot point so that its center will lie on a line extending at right angles thereto from the point to which the edge of the outer face intersects the edge of the adjacent face on the movable jaw.
Another object of the invention is to so arrange the movable jaw that its outer face will be parallel to tangents to the curve forming no the outer end of the wrench regardless of the size of the nut that may be placed within the jaw.
Another object of the invention is to shape the end of the handle adjacent the movable jaw, i. e., the fixed jaw, so that it will, in complement with the movable jaw, precisely fit four sides of the largest size hexagon nut the wrench is supposed to take.
Another object of the invention is to pro- 40 vide an adjustable wrench which will increase the area of cont-act therewith as the size of the nut to which the wrench is applied increases.
Other objects of the invention will appear as the description proceeds.
An embodiment of the invention is shown in the accompanying drawings in which the same reference numeral. is applied to the same portion throughout, but we are aware that there may be modifications thereof.
Fig. 1 is a side elevation of the vwrench complete, as it appears without a nut in place therein;
Fig. 2 is an edge view of the wrench;
Fig. 3 is a side elevation of the wrench,
with the handle broken away showing a form and ordinarily made of drop-forged steel. The handle is slotted at 2 to receive the inner part 3 of the movable jaw and is pivoted at 4, the pivot being placed close to the meeting point of the flat surfaces of the fixed jaw, whereby the surface 9 will be in alinement with the surface 5 when the jaws are in the full open position.
The movable jaw has a tail-piece 5 which extends through the handle and enables the operator to place his thumb thereon to shift the movable jaw and hold it in any desired position when he may be attempting to turn a nut.
The movable jaw has three faces, as shown at 5, 6, and 7, which said faces form portions of three sides of a hexagon.
The end of the. handle forming the fixed jaw has two faces 8 and 9 which form two faces of a hexagon, the pivot point 4 is arranged on a line extending from 10 to 11 which is at right angles to the face 7, the
object being to give the best holding effect on the nut and to prevent the either binding or slipping off.
In operation the wrench is turned clockjaw from Wise (see Fi s. 1- and 3 to 6 inclusive), the
movable jaw eing applied to the nut by the operator pressing upwardly on the tailpiece 5'.
The movable jaw is held against the fixed jaw normally by means of a spring 1'.
What we claim is as follows, but modifications may be made in carrying out the invention shown in the drawings and in the ahove particularly described form thereof, said jaws are in the full open position, said within the purview of the invention as defixed jaw having a curved surface adapted fined by the annexed claim. to engage one side of a hexagon nut While In a wrench comprising a handle, a fixed said pivoted jaw is in engagement with two 15 jaw on said handle having two flat faces sides thereof.
