Abstract: Tongue and groove pliers include a first member having a slot, and a second member connected to the first member by a pin in the slot. The first member has a plurality of arcuate ribs defining open ended grooves on the side adjacent to the second member. The second member has a tongue on the side facing the first member. The tongue fits in a selected groove to adjust the spacing between opposing jaws on the respective first and second members. The pliers have at least one visual alignment feature to align the tongue with a desired groove. The alignment feature can be readily visible marks indicating locations of the tongue and/or grooves.

Abstract: Self adjusting grooved pliers include a first section having a jaw portion and a channel formed therethrough, adjacent the jaw portion and a second section having a jaw portion and a pivot extending therefrom. The pivot is slidably received in the channel to allow wider or narrower association between the jaw portion of the first section and the jaw portion of the second section. The pivot pivotally couples the first section to the second section for movement between an open position and a gripping position. A plurality of grooves is formed in the first section and a tongue extends from the second section. The tongue is received in one of the plurality of grooves, locking the pivot in position within the channel only upon the first section and the second section reaching the gripping position. A biasing assembly acts on the pivot, urging the pivot upward in the channel toward the jaw portion of the first section.

Abstract: A slip joint adjustable jaw pry tool is a plier configured tool which has opposing jaws facing outboard. There are two levers, a first and a second lever, each of which include a jaw portion and a handle portion. There is a channel with intersecting arcuate grooves provided on the first lever, between the handle and jaw. The second lever is provided with a pivot center point and an arcuate protuberance concentric to the pivot center point, between the handle and jaw. The levers extend substantially parallel to each other. The range of dimensional movement of the jaws, relative to each other, is determined by adjusting the location of the pivot center point of the second lever, in the channel of the first lever. This is accomplished by disengaging the arcuate protuberance of the second lever, from a given arcuate groove of the first lever, moving the pivot center point of the second lever along the channel of the first lever, and engaging the arcuate protuberance in a different arcuate groove.

Abstract: Pinch free gripping pliers are described including first and second pivoted legs joined by a pivot bolt. The pivot bolt is mounted to the first leg and is slidably received in an elongated slot in the second leg, thereby enabling the pliers to have multiple jaw opening ranges. An arcuate rib on the shank of one leg engages and meshes with any selected one of several arcuate grooves formed in the second leg, thereby maintaining the setting of the pivot bolt. An overtravel stop member is located on the first leg, facing an edge surface on the second leg that is acutely angled relative to the slot. The overtravel stop member and edge surface engage as the handles of the pliers close, limiting further closing and preventing the handles from coming together closer than a predetermined safety distance. The predetermined safety distance is the same at each of the multiple jaw opening ranges, by provision of the angled edge surface.

Abstract: Adjustable jaw plier tool having crossed pivotably engaged handles one of which is slotted, and one of which has an affixed pivot pin. An integral over travel element is positioned on the rearward portion of the working surface of the jaw of the handle having the affixed pivot pin to avoid the possibility of hand injury by bearing against an elongate portion of the slotted handle.

Abstract: This disclosure is directed to the use of an adjustable hand tool which employs means to prevent the separation of the cross members. Specifically the invention uses an arcquate circular cross section rib which selectively engages one of several arcquate circular cross sectioned grooves. The pliers further have a pin with a cap at one end and externally threaded at the other. The pin has internal threads with a securing screw threadably mounted therein. A threaded cap is threadably attached to the pin and the securing screw tightened against the cap to cause it to remain in its selected position.

Abstract: A manufacturing process for tongue and groove pliers that involves forging plier members with a bend between the nose and handle portions, forging arcuate projections on the members with mating surfaces on the projections. The surfaces having an angular orientation relative to the adjacent plier surface of 90.degree. minus an angle that is less than the supplement of the angle of the bend, and straightening the members so that the mating surfaces, when engaged, tend to urge said plier members relatively toward each other.

Abstract: An adjustable cam-operated jaw plier wrench fitted with an integral, handle-mounted overtravel stop member is described. The integral overtravel stop member is permanently affixed to one of the two jaw-handle portions of the plier wrench. In operation, the fixed overtravel stop member's outer surface abuts the opposite jaw-handle member edge surface, thereby preventing handle overtravel along with its usual attendant injury to the hand of the operator during normal use of the tool. The position of the integral overtravel stop member will allow ready adjustment of the jaw plier wrench to any of its preset adjustable positions.
