Abstract: A novel carpet seaming method and tools for reducing or eliminating seam peaking and profiling is provided. The backing of abutting pieces of carpeting can be reinforced along their respective edges. A staple is supported on an anvil with its legs facing the carpet backing beneath the seam line while a hammer is driven onto the carpet pile and the underlying staple base. The impact of the hammer impales the carpet backing over the legs of the staple, and compresses the staple base against the anvil. The legs can then be forced towards each other to lock the staple in position. The process is repeated along the length of the seam line until a row of staples spaced apart from each other by a predetermined distance and extending from one end of a seam to the other end securely holds the abutting pieces of carpet together to form a seam. After seaming, the carpet may be stretched conventionally and secured to tack strips along the periphery of the area being carpeted.

Abstract: An electric powered multiple impact fastener driving tool comprising a handle portion, a main body portion, a guide block, a magazine, and a guide and biasing assembly mounted in the guide block and affixed to the magazine enabling shifting of the magazine within the guide block between an extended fastener starting position and a retracted fastener driven position. The main body portion contains an impact assembly comprising a motor driven cam wheel with a single drop-off, a cam follower roller mounted on a reciprocable hammer, a compression spring surmounting and abutting the hammer, and a fastener driver.

Abstract: A nail driving apparatus comprising a tube, a rod with a mass attached to one end, a spring connecting the mass to the tube, and a sleeve encircling the exposed portion of rod between the tube and the mass. When the mass is in the forward, closed position, the spring is slightly stretched, holding the apparatus in the closed position. When the mass is drawn away from the tube, the spring is displaced, increasing the tension in the spring and, thus, aiding the user in driving a nail. An expandable sleeve protects the exposed portion of rod between the tube and the mass from being contaminated by debris. It also prevents the user's hand from being positioned at the point of contact. As the mass is drawn away from the tube, the sleeve expands to protect the entire length of exposed rod.

A push blade is guided by the guide ribs for sliding up and down to release and drive in the staples. A top part partly covers the body and acts as an operating arm. A locking and release device for the push blade is operated by the top part. The locking and release device has a pivotable latch being disposed between the top part and the body and is releasably joined to the push blade for intermittently locking the push blade in a locked position relative to a staple in the strip and for releasing the push blade in an unlocked position.

Abstract: A spring actuated fastener driving tool has a lift pawl, bearings for supporting the lift pawl for pivotal movement about a first axis into and out of engagement with a power spring, and an operating handle continuously engageable with the bearings and intermittently engageable with the lift pawl. The operating handle is supported by a housing for pivotal movement about a second axis parallel to the first axis through successive driving cycles each including a loading phase during which the pawl remains engaged with the power spring as the power spring is resiliently deflected and loaded, and a release phase during which the pawl is disengaged from the power spring. The housing and the operating handle have guide surfaces which coact in sliding engagement with the bearings to accommodate movement of the bearings towards a reference plane containing the second axis during at least the loading phase of the drive cycles.

Abstract: A manually powered fastening tool which stores and instantly releases the energy of a spring such that it may force a staple type fastener into an object by an impact blow. In the present invention the squeeze handle is hinged near the end of the tool body opposite the end from which the staples exit. The user grips the tool near the staple exit end and pushes the squeeze handle toward the intended staple impact point. This novel arrangement causes the user to force the staple into the receiving object with the same hand that pushes the squeeze handle toward the tool body, while the prior art typically requires use of a second hand to hold the tool firmly upon the staple impact point. Improving from the prior art, the present design ensures that the staple exit end of the tool body will not lift away from the receiving object. The energy storage spring and handle engagement linkage are located remotely from the plunger in the present design.

Abstract: The driver is disclosed for a surgical micro-suturing stapling system which does not require the use of a staple bending anvil tha must be retracted after the staple is implanted. The surgical microstapler system utilizes a unique stapler head comprising a staple magazine having a series of staples attached to and supported by a surrounding frame, apparatus for advancing the staple magazine so as to position its leading staple in a predetermined dispensing position, and staple driving apparatus for implanting the leading staple into the tissue through the ejection slot.

The staple driving mechanism comprises a linearly movable staple driving blade and resilient means extending transversely of the path of movement of the blade and biasing the blade towards a staple ejection slot, the blade being movable by the trigger out of the staple ejection slot against the action of the resilient means whereby the blade is driven to eject a staple upon release of the blade by the trigger.

Abstract: This invention relates to an electric impact tool characterized by a pair of electric motor-driven counterrotating flywheels, at least one of which is movable relative to the other from a retracted inoperative position into an extended operative one closely adjacent the other flywheel whereby a ram is squeezed therebetween and impelled forward at high speed against a workpiece. The nosepiece of the tool frame is retractable although normally extended due to the spring bias urging it and the movable flywheel to which it is mechanically linked into disengaged position. These elements cooperate with one another and with a manually-actuated trigger such that the latter must be depressed and the nosepiece retracted in order to engage the high energy friction clutch defined by the flywheels so as to operate the ram. A flywheel speed control is provided for matching the ram impact to the workload.
