Abstract: One modular ratchet adapter for use with an opposed jaw tool features a wishbone armature (140), (150) supporting a ratchet head (160) while being centered within an elastomeric grip (110). The grip (100) is secured within two jaws of a tool, such as adjustable wrench (200), which interface about a trough (130) defined by the grip (110). An alternate modular ratchet adapter may feature an adapter module and a custom grip housing designed to interface with a given brand and size of adjustable wrench (200). This allows a singular ratchet adapter design to be manufactured while the grip housing may be more economically produced to enhance utility across multiple platforms. Either ratchet adapter may be used between the jaws (210, 230) of a given adjustable wrench (200) or other tool with opposed jaws.

Abstract: A compact three torque application point, ratcheting open- wrench, wherein the operated first and third torque application points are under tension gripping and pulling around their corresponding fastener driven half face whilst the second torque application point is under compression pushing its corresponding fastener driven half face. Contact with the worked fastener driven half faces being in generally the same point within each driven half face largely equalizing any lever arm force applied. The head portion fastener access being approximately at 90 degrees to the handle portion and the second torque application points radiused leading edge is incorporated near the extremely strong point of convergence between the handle portion and the head portion resulting in a far greater inherent ratcheting open- wrench torque capability as there is now no circumstance that the normally susceptible second jaw can either flex or fail as in effect there is no second jaw as such.

Abstract: A socket adapter for limiting torque delivered from a tool to a socket piece. The socket adapter includes a female receiver that is coupleable to and driven by the tool, and a male drive that is coupled to and driven by the female receiver for transferring torque to the socket piece. The socket adapter further includes a clutch mechanism having a first clutch surface, a second clutch surface that engages the first clutch surface, and an adjustment mechanism for adjusting a clamping force between the first clutch surface and the second clutch surface. The second clutch surface slides relative to the first clutch surface when a reaction torque exerted on the clutch mechanism exceeds a predetermined torque limit.

Abstract: A breakaway threaded fastener is provided. The fastener has a stud, a pin, and a cap. The stud has a hollow cavity with a closed end, an open end, a wall, and an outer surface. The outer surface has an external thread. The pin is in the hollow cavity. The pin has a first end at the closed end of the stud and a second end extending above the open end of the stud. The cap has another hollow cavity with a closed end, an open end, and an internal thread. The cap is threadably engaged to the open end of the stud via the internal and external threads so that the second end of the pin abuts the closed end of the cap.

Abstract: A hand tool includes an elongate, plate shaped steel core having a top face and a bottom face in parallel planes, a drive head portion formed at one end of the steel core and having a drive head cavity formed therein, a tang portion extending from the drive head portion to the other end of the steel core, a ratchet assembly disposed in the drive head cavity, and a first encapsulation layer covering the tang portion and the drive head portion, but not covering at least a portion of the ratchet assembly. The first encapsulation layer may include a fiber reinforced plastic composite material.

Abstract: A wrench (10) has a roller motion transmission mechanism that changes reciprocating motion of a driving member to unidirectional rotational motion of a driven member. The wrench (10) has a head (17) with an inside cylindrical wall surrounding a body (18) with a plurality of protrusions (37,38,39,40,41,42,43,44). Each protrusion (37,38,39,40,41,42,43,44) has a ramp (48) inclined toward the cylindrical wall (24). A wedging member (53,54,55,56,57,58,59,60) comprising a cylindrical roller engages each ramp (48) and inside cylindrical wall (24) of the head (17). A cage (52) anchored to the protrusions (37,38,39,40,41,42,43,44) retains the wedging members (53,54,55,56,57,58,59,60) in engagement with the ramps (48) and the inside cylindrical wall (24) of the head (17).

Abstract: The ratchet mechanism comprises a head portion with a circular central housing, the inner surface adjoining the handle portion having a further recess characterized by a plurality of engagement ramp profiles arranged not unlike low angled gear teeth within the recess arc. A pawl is located within the recess, with a corresponding plurality of engagement ramp profiles abutting the recess engagement ramp profiles and incorporating an inner facing toothed face of similar corresponding pitch and profiles as the drive element teeth in order that they can mechanically mesh into one another when ratchet is operated in the drive direction, the pawl inward force being substantially evenly distributed along the pawl toothed front face by the use of several similar engagement ramp profiles urging all the pawl teeth into the required locking engagement with the drive element simultaneously.

Abstract: An electrically isolated adapter may include a drive body made of first metallic material extending along a common axis, a driven body made of a second metallic material extending along the common axis, and an isolation assembly formed of insulating material disposed between the drive body and the driven body. The drive body may include a drive head configured to interface with a socket or fastener. The insulating material has a resistance to electrical current that is higher than the resistance to electrical current of at least one of the first metallic material and the second metallic material. The driven body may include a drive receiver configured to interface with a protrusion of a driving tool. A portion of one of the drive body or the driven body is received inside a portion of the other of the drive body or the driven body such that the drive body and driven body overlap each other along the common axis.

Abstract: Herramienta para apretar o aflojar distintos elementos unidireccionalmente, independientemente del sentido de giro del eje de entrada (llave bicarraca) que consiste en una herramienta o accesorio para herramientas capaz de apretar o aflojar tornillos unidíreccionalmente independientemente del sentido gire que apliquemos en un eje de entrada (1), reduciendo ei número de movimientos necesarios por las herramientas existentes, para apretar o aflojar, por ejemplo un tornillo, y que se caracteriza porque está formado por una carcasa (13)que interiormente tiene una tecnología utilizada en los convertidores de energía, configurado para convertir Sos movimientos de distintos sentidos de giro, aplicados en un eje de entrada (1), en movimientos rotativos unidireccionales en un eje de salida (2) que es paralelo al eje de entrada, y está dispuesto de forma que podamos dibujar un piano de corte que parte a la mitad los dos ejes, quedando los extremos de los ejes (3.1,3.2, 3.3,3.4) a la vista o fuera de la carcasa, con la particularidad de que podemos acoplamos en el eje de entrada en un extremo (3.1 ) u otro (3.2), ya que según el extremo del eje de entrada que utilicemos, los elementos que se acopien al eje de salida |2) giraran en sentidos contrarios unidíreccionalmente en cada uno de sus extremos (3.3 y 3.4), según queramos apretar o aflojar un tornillo.
