Abstract: A nozzle for seating a tubeless tire on a rim using pressurized gas includes an outlet, a jet configured to accept pressurized gas and emit a stream of gas through an orifice into a chamber. As the stream of gas enters the chamber, the Venturi effect causes air to enter the chamber through air intake ports and the stream of gas and air from the air intake ports is blown out of the outlet of the nozzle. A system for seating a tubeless tire on a rim includes the nozzle, a tank and a valve configured to control the flow of pressurized gas from the tank to the nozzle. The tire may be seated on the rim by positioning the system so that the air from the nozzle blows into the tire between the bead of the tire and the rim if the valve is opened.

Abstract: A ratchet wrench includes a wrench body having a circular space defined at a head portion of the wrench body, a ratchet with a hollow center placed into the circular space. The ratchet is symmetric to the wrench body. The inner wall of the ratchet has a plurality of first ridges formed thereon. A first recess is formed between each of two adjacent first ridges. Each of the first recesses selectively has a second ridge formed thereon. A second recess is defined on the second ridge. The shape of the second recess is as same as the first recess. In this way, a user can directly alternate the big and small bolts in the ratchet wrench, rather than turn over the wrench to fit the big or small bolt.

Abstract: A clamp device (30) includes a plurality of arms (32, 34). One of the arms supports a securing member (36). The other arm includes a curvilinear surface (40) that directly engages a curved wall of an article at a location in line with a centerline of the securing member. The curvilinear surface (40) allows for the clamp device to reliably engage an article having a curved wall for a lifting operation. One example use of a disclosed example device is for lifting tubes associated with a hydraulic elevator system.

Abstract: A multi-functional gardening implement that, in some embodiments, functions as a pair of shears, a spade, a garden cultivator, a saw, a machete, a weeder and a rake. The implement comprises two shears that cooperate to cut vegetation placed between them when a user presses the handles of the shears together. The implement also has at least one appendage, which may be a shovel, a hoe, a garden cultivator, or another garden tool that is attached to the central portions of the shears and can be rotated to an operating position where the appendage is supported by the blades of the shears. The implement may have a second appendage that rotates in the opposite direction to a similar operating position against the other sides of the blades. In some embodiments, the cutting portions of the shears may be configured to define a spade blade in the closed position.

Abstract: A device for extracting a cork from a bottle comprising a generally T-shaped handle mounted on a housing having an upper end and a lower end, a shaft which is operatively connected to handle for axial and rotational movement therewith, the shaft having a hollow passage with an air intake and an air exhausting hole. The shaft depending from the lower end of the housing for griping and penetrating the cork longitudinally thereby presenting the air exhausting hole to the interior of the bottle. A pump configured to push for selectively pumping air from the housing through the shaft into the bottle between the cork and the contents of the bottle such that air in the bottle forces the cork out of the bottle in conjunction with force applied by pulling the T-shaped handle.

Abstract: A dual-drive self-ratcheting device, that efficiently converts alternating clockwise and counterclockwise rotation applied to its input, into unidirectional rotation at its output, by employing a plurality of means, such as, but, not limited to, ratchet and pawls or roller-type clutch mechanisms, oriented the same and arranged in tandem, on a common drive shaft and caused to alternately drive the shaft continuously in either all clockwise or counterclockwise direction, as oscillatory motion is applied to its input; while the first ratchet and pawl or roller clutch mechanism is caused to impart motion onto a drive-shaft, the second ratchet and pawl or roller clutch mechanism is simultaneously caused to override the driveshaft; while the second ratchet and pawl or roller clutch mechanism is caused to impart motion onto a drive-shaft, the first ratchet and pawl or roller clutch mechanism is simultaneously caused to override the driveshaft; hence regardless of the direction of rotation applied to the input, the

Abstract: An attachment is mated to a power screwdriver by use of an adapter that is first fixed onto the screwdriver. The attachment includes an automatic fastener driver that receives a collated strip of fasteners, and drives them into a working surface. The attachment is mated to the adapter; the attachment contains a radial type of mechanical coupling that can be rotated without dismounting the attachment from the power screwdriver. In this manner, the angular orientation between the attachment and the power screwdriver can be changed “on the fly” by the user. This combination allows the user to keep his or her hands at their operating positions throughout this procedure, thereby allowing the user to re-commence using the combination tool quickly after readjusting the operating angle.
