Definitions

  • the conventional types of adjustable wrenches normally comprise a main wrench portion having a fixed jaw, and a movable jaw located on the main wrench portion.
  • Such conventional adjustable wrenches have the disadvantage that movement of the movable jaw from one position to another is tedious and time consuming.
  • the movable jaw is positioned comparatively loosely on the fixed portion of the wrench and may easily, during use, gradually move away from the pre-set position until finally the wrench no longer fit-s, for instance, the nut on which it is being used, but slips around the corners of the nut, rounding and disfiguring these.
  • FIG. 1 is a perspective, part-cutaway view of an adjustable wrench embodying this invention.
  • FIG. 2 is a perspective part-cutaway view of an alternative means of embodying this invention in an adjustable wrench.
  • FIG. 3 is a fractional, sectional, side elevation of the wrench illustrated in FIG. 1, showing in enlarged detail the adjustable locking mechanism in the locked position.
  • FIG. 4 is a fractional, sectional, side elevation of the wrench illustrated in FIG. 1, showing in enlarged detail the adjustable locking mechanism in the released position.
  • an adjustable wrench comprising a main body portion 1 having at one end thereof attached a fixed jaw 2 that may be supplied with serrations 3.
  • Main portion 1 contains a groove 4, closed at one end with an end plate 5, main portion 1 being adapted to constitute a guide for a movable jaw 6 having a nether portion 7 adapted to encompass and slide longitudinally on main portion 1, main portion 1 being adapted to guide and maintain movable jaw 6 in substantially parallel and opposing position to fixed jaw 2.
  • edges 8 of groove 4 are adapted "ice to be located substantially parallel, and engage with the end surfaces 9 and 10 of L-shaped abutment members 11 and 12 respectively, members 11 and 12 being swivably located within a chamber 13 in movable jaw 6 on spindle 14 located transversely of movable jaw 6, in a direction substantially at right angles to the longitudinal direction of main portion 1.
  • L-shaped abutment members 11 and 12 are opposingly located on spindle 14, the fulcrum of rotation of members 11 and 12 being located substantially toward the corner of each member, yet maintaining the one arm of each member that contacts edges 8 in such a position that a line reaching from the center of spindle 14, perpendicular to edge 8 will at all times fall within the outer edge of the end surfaces 9 and 1d of quadrants 11 and 12 that is adapted to contact edges 8.
  • a manual release lever 15 is hingeably located on movable jaw 6 and adapted to act longitudinally on a stud 16 attached to a yoke 17 having two ends 18 and 19 adapted to respectively act on the free ends 20 and 21 of quadrants 11 and 12 respectively.
  • a spring 22 is adapted to exert force, pulling ends 9 and 10 of members 11 and 12 respectively toward each other to assist in jamming action of movable jaw 6 on main portion 1.
  • a spring 23, shown specifically in FIG. 1, is located on guide rod 24, which is firmly attached to end piece 5 at one end of guide rod 24, the other end of guide rod 24 projecting slidably through a hole 25 in movable jaw 6, spring 23 being adapted to actuate movable jaw 6 to approach fixed jaw 2 upon jamming action between movable jaw 6 and main portion 1 being released.
  • lever 15 permits spring 22 to contract, thereby causing members 11 and 12 to pivot arcuately inwardly about spindle 14 and their respective ends 9 to 10 to contact oppositely located edges 8 of main portion 1, thereby resuming the locking action between movable jaw 6 and main portion 1 as shown in FIG. 3.
  • an alternative configuration of an adjustable wrench embodying this invention comprising a main portion 26 having fixed jaw 27 and a movable jaw 28 slidably located on main portion 26.
  • a series of teeth is located on top of each side wall 29 and 30 of main portion 26, main portion 26 having the configuration of a channel section, the teeth on walls 29 and 30 beig of ratchet shape, the teeth on wall 29 being located in a direction opposite to that of the teeth on wall 30.
  • a spindle 31 located in movalble jaw 28, transversely of the longitudinal direction of main portion 26, carries two pivotable pawls 32 and 33, pawls 32 and 33 being opposingly located and adapted with one end to engage teeth on walls 30 and 29 respectively, the other end of each of pawls 32 and 33 being in contact with a yoke 34 adapted to be actuated by a manual lever 35, hingeably located in movable jaw 28, through rod 36.
  • a spring 37 is adapted to draw the two free ends of pawls 32 and 33 together, thereby maintaining contact between pawls 32 and 33 and the teeth on walls 30 and 29 respectively upon no manual pressure being exerted on yoke 34 through lever 35.
  • a spring 44, guided by rod 38 is adapted to exert longitudinal actuating pressure between transverse end plate 39 and movable jaw 28.
  • the action of the release mechanism is substantially the same as that previously described under FIGS. 1, 3 and 4 inasmuch as manual pressure on lever 35 will, through yoke 34, press down on yoke ends 40 and 41 of pawls 32 and 33 respectively, thereby raising free ends 42 and 43 respectively out of engagement with the teeth on walls 30 and 29 respectively, permitting spring 37 to actuate movable jaw 28 to move towards fixed jaw 27 to engage, for instance, with a nut, etc.
  • this wrench lends itself for automatic adjustment, since it is merely necessary to place the wrench over the nut that is required to be turned, whereafter pressure on the manual actuating lever automatically will close the movable jaw towards the fixed jaw until the adjustable wrench fits the pertinent nut.
  • a channel section body portion comprising a bottom wall, a first side wall and an oppositely located second side wall, a rear end wall and a front end wall, said front end wall extending perpendicularly outwardly from said bottom wall and said first side wall and said second side wall to form a fixed jaw member, a hollow, movable jaw member slidably located on said body portion cooperative and coplanar with said fixed jaw member, a transverse spindle located within said movable jaw member, a first L-shaped abutment member having a vertical arm and a rearwardly extending horizontal arm pivotally attached to said transverse spindle at the junction of said vertical arm and said horizontal arm, a lower edge of said vertical arm abutting the upper edge of said first side wall of said body portion, a second L-shaped abutment member having a vertical arm and a forwardly extending horizontal arm pivotally attached to said transverse spindle at the junction of said vertical and horizontal arms, the lower edge of said vertical arm abutting
  • a bias spring means located within said body portion extending between said rear end wall and said movable jaw member, a bias spring mounting rod coaxial with said bias spring having one end fixedly mounted in said rear end wall and said movable jaw member slidably mounted upon the opposite end of said bias spring rod.
  • a channel section body portion comprising a bottom wall, a first side wall and an oppositely located second side wall, a rear end wall and a front end wall, said front end wall extending perpendicularly outwardly from said bottom wall and said first side wall and said second side Wall to form a fixed jaw member, a plurality of rearwardly extending ratchet teeth formed on the upper edge of said first side wall and a plurality of forwardly extending ratchet teeth formed on the upper edge of said second side wall, a hollow movable jaw member slidably located on said body portion cooperative and coplanar with said fixed jaw member, a transverse spindle located within said movable jaw member, a first L-shaped pawl member having a vertical arm and a rearwardly extending horizontal arm pivotally attached to said transverse spindle at the junction of said vertical arm and said horizontal arm, a toothed lower edge of said vertical arm contacting said rearwardly extending ratchet teeth on said first side wall of said body
