Abstract: A cork screw which comprises a pedestal and a rotary handle incorporating a stem and a penetrating screw wherein the pedestal incorporates a dog member to engage with a helical groove of the stem and a spring biased sleeve around the stem to cause the dog member to engage with the helical groove when the handle is turned in a certain direction and disengage therefrom when a cork is pulled entirely out of a bottle. A holding member is incorporated in the pedestal to hold a cork after it has been pulled out of a bottle.
Abstract: An adjustable open-end wrench having an elongated body member, one end of which is a handle, and the other end of which includes a fixed jaw portion and jaw-base portion having a reentrant groove therein with a movable jaw member slidably mounted in the reentrant groove and a rack portion on the bottom of the movable jaw member for interaction with a second rack member located in another chamber in the body member located just below the reentrant groove, that chamber also housing the interior end of a button member which extends to the exterior edge of the wrench body member, and a lever member and biasing means for biasing the button member outwardly while biasing the rack members into engagement with each other. By simply pushing the exposed portion of the button member, the movable jaw is released for slidable adjustment of the width of the open-end wrench opening.
Abstract: A device for mounting and demounting a beaded pneumatic tire onto and off of a wheel which is particularly adapted for facilitating fitment of a well obstructor onto the well of the wheel. The device has a wheel support assembly which includes an upwardly extending spindle for supporting the wheel. The spindle has axially disposed internal female threads and has an exterior dimensioned so that the spindle can be freely inserted into the axial hole in the wheel. A removable bead pusher assembly is included which has a thrust collar, pusher arms, and a circumferential bead pusher ring connected to the ends of each of the pusher arms. A removable thrust assembly is provided which has a rotatable male threaded member which threadably mates into the female threads of the spindle and has a thrust face adapted to bear against the thrust collar.
Abstract: A tattooing device includes a disposable syringe in which a tattoo dye is dispensed through a passageway in a needle of the syringe. A cam member is rotated to rotate a clutch rod held in a clutch member. The clutch rod rotates a threaded rod through a fixed nut member that causes the threaded rod to move linearly towards the syringe to displace a plunger pin fixed to the threaded rod. The plunger pin thereby displaces a plunger of the syringe to dispense the tattoo dye through the needle.

Abstract: A steel U-shaped pair of gripping arms are formed from steel having the proper size and shape to fit over the end of a lamp bulb. The tips of the gripper arms are formed to fit the end of the bulb and the steel is then annealed to obtain the required spring characteristics. The tips of the gripping arms are covered with plastic to provide friction between the gripping arms and the bulb. A chain is attached between the arms with a second chain attached to its center. Pulling the second chain will close the gripping arms. A slot is provided to secure the second chain to hold the arms at any desired span. Extensions can be attached to the gripper arms when the device is used on high overhead lamps. The steel used in the gripper arms is thin to fit between the bulb and fixture when the bulb is mounted in deep fixtures.
Abstract: A knife or blade is sharpened by using an apparatus which includes a magnetic guide having a magnetic knife guide surface in a plane at an angle to and intersecting the abrasive surface to form a line of intersection therewith. The magnetic guide surface has north and south magnetic poles along lines substantially parallel to the line of intersection. One pole is along a portion of the guide surface remote from the abrasive surface and the other pole is along a portion of the guide surface contiguous to the abrasive surface.
Abstract: An improved surface blasting apparatus for cleaning a surface to be treated by throwing abrasive against the surface at high velocity, then recovering and cleaning the abrasive for reuse. The abrasive rebounding from the treated surface is directed against a magnetic receiving member around which a quantity of the ferrous abrasive forms a protective envelope, with additional high speed abrasive striking said envelope and consequently losing kinetic energy. Means is provided for removing debris from the abrasive by entraining the debris in a flow of air through the apparatus. The debris is separated from the air stream by cyclonic rotation in a dust collector. An alternate embodiment includes a deflector plate to prevent the undesirable escape of abrasive forward of the apparatus. Another embodiment provides for a weighted roller with sharp spikes protruding radially outwardly therefrom to puncture surface coatings which are difficult to remove by normal blasting procedures.
Abstract: A wrench includes an upper jaw integral with a handle and a force multiplying cam member pivotally mounted on the handle. A lower jaw has a pivot point for pivoting relative to the cam member and the upper jaw. A sliding bar is mounted inside the handle to slide with respect thereto. A free end of a first toggle linkage member is pivotally connected to an ear of the lower jaw and a free end of a second toggle linkage member is pivotally connected to the sliding bar so that the pivot point can move relative to the handle. A tension spring extends between the ear and the lower jaw to urge it away from the upper jaw. An extension integral with the first toggle member forms a second handle coextensive with the first handle and cooperates therewith to move the jaws toward each other as the handles are squeezed together. Such movement continues until the jaws contact an associated object. Continued squeezing of the handles causes the second toggle member to move the sliding bar back from the upper jaw.
