  • My invention relates to an improvement in adjustable socket wrenches.
  • Heretot'ore straight or monkey wrenches have been constructed of two arms, one being U-shaped to receive the other arm, the outer ends of said arms beiugpivoted or hinged together for opening and closing.
  • the head ofthe wrench was provided with a right-andlei't-hand screw and thumb wheel for opening and closing the wrench.
  • My invention relates to wrenches having an adjustable socket, the wrench being rotated on a line extending through the longitudinal axis of the socket, the object being to dispense with the hinges or pivoted connection between the two arms of the wrench and secure the two arms together in a rigid manner, and thus insure spring-arms having a tendency to close, while between the two halves of the wrenchstock are inserted a right-and-left-hand screw and thumb-wheel for adjusting the size of the socket as desired.
  • Figure 1 is a side view of my improvement, partlyin section.
  • Fig. 2 is a view of the same turned onequarter around.
  • Fig. 3 is a cross-section of the same taken through the line .90 m, Fig. 2.
  • Fig. 4 is a cross-section of the same taken through the line y y, Fig. 2.
  • Fig. 5 is a crosssection of the same taken through the line 22, Fig. 2.
  • the stock A is made of metal in T form and has sockets in the ends of its three arms.
  • the socketA is madein two parts, the plane of division passing through the three arms, as shown in Fig. 2, and the two parts are rigidly secured to each other at or near the intersection of the three arms by rivets and by the steel bands B, shrunk upo'n the ends of the short armsA, as shown in Figs. 1 and 2.
  • the two halves of the arm A are made broadest in arm of the wrench A is formed a projection,
  • the projection C passes through and fits into a slot or mortise, D, formed in the other part of the said long arm of the wrench, as shown in Figs. 1, 2, and 3.
  • the screw G is a screw which passes through a holein the center of the thumb-wheel F, and is secured at-its center to the said wheel, so that the said screw will be turned by turning the said wheel F.
  • the screw G has a right-hand thread upon one end and a left-hand thread upon the other end to fit into screw-holes in the parts of the long arms of the wrench A, so that the said parts will be spread apart to enlarge the socket in the end of the said long arm by turning the thumb-wheel F in one direction, and will be drawn together to contract the said socket by turning the said thumb-wheel F in the other direction.
  • the screw G assists the projection C in supporting the parts of the long arm of the wrenchagaiust the torsional strain when the wrench is being used.
  • the arms being permanently secured to each other at one end, must be comparatively thin in one direction to insure sufficient spring or elasticity for opening and closing and of greater width in theopposite direction to withstand the torsional strains. 7
  • the stock must be of sufficient size to enable the socket to be formed in its end, and hence quite a large-sized thumb-wheel is required,
  • Recesses E in the inner faces of the arms receive the sides of the thumb-wheel and enable the socket to be completely closed, while but a slight portion of the periphery of the thumb-wheel projects beyond the opposite faces of the stock.
  • the spring-arms A rigidly fastened together at one end and constructed with a divided socket in their opposite ends, in combination with a right-and-left-hand screw and a thumb-wheel for adjusting the socket, substantially as and for the purpose set forth.
  • a socket-wrench the combination, with two arms rigidly secured together at one end and provided with an enlarged stock at their opposite ends, having a divided socket formed therein, said arms being made broadest in a line at right angles to their line of opening and closing, of a right-and-left-hand screw and a thumb-wheel for opening and closing the divided socket, substantially as and for the purpose set forth.
  • An adjustablesocket-wrench consisting of two long arms rigidly secured together at one end and provided with a divided socket in their opposite ends, a right-and-left-hand screw and thumb-wheel for adjusting the socket, and two short arms formed integral with the fixed ends of the long arms and arranged at right angles thereto, substantially as and for the purpose set forth.
