  • Patent number: 11945079
    Abstract: A screwdriver includes a main body and a switch. The main body is coupled to a handle and includes a pair of parallel, spaced apart slots, and a pawl positioned in each slot. Each pawl is biased outwardly by a spring. The switch is pivotable relative to the main body, and the switch includes a groove extending along an arcuate portion of an inner surface. Pivoting the switch in a first direction moves the switch toward a first position in which the groove is positioned in-line with the first pawl. When the switch is in the first position, the first pawl extends outwardly from the slot and engages the internal tooth surface such that application of a torque in a first direction drives a shank in the first direction and application of a torque in the second direction causes the shank to ratchet relative to the main body.

  • Publication number: 20240010025
    Abstract: A chalk reel is provided that includes a handgrip on housing supporting a chalk line extending from a nozzle of the housing that extends from the chalk reel to mark a straight line. The chalk reel may further include a rotatable handle that rotates to extend or retract (“pay out”) the chalk line. A hook is secured to the end of the chalk line to facilitate extension of the chalk line and prevent retraction of the chalk line end into the housing nozzle. The chalk reel may further include a transmission system with gearing and a selector to lock the gearing at locations around the handle rotation. The chalk reel may also include a large removable cap to facilitate refilling the chalk or other marking material.

  • Publication number: 20230264333
    Abstract: A hammer is provided that includes a handle, a head, a striking insert, and a claw. The hammer provides for a head with a keyed hole to couple to a keyed projection on a striking insert. The head also includes a dovetail projection that couples to the dovetail connection of the claw. Each component may comprise a different material. For example, the striking insert and the claw comprise one material, and the handle and the head comprise another material. In some embodiments, a slotted punch with a magnetic retainer creates a bore through the face of the head and the striking insert to support a fastener (e.g., a nail) within the head.
