Abstract:
A new and improved interconnection is provided between the striking element and handle of a percussive tool. The striking element is provided with an eye having side walls converging from both ends thereof to provide a portion of reduced cross section located at the axis of percussion of the tool and the tool handle is of generally rectangular cross section with its corners tangentially and frictionally engaging the portion of reduced cross section to provide an interference fit therewith. The interconnection permits adjustable positioning of the head relative to the handle for achieving a balanced angular relationship between the striking face of the head and the handle of the tool. A suitable impact resistent resin fills the cavity between the handle and the side walls of the eye to form a sleeve extending continuously along the length of the aperture on each side of the handle, but gradually increasing in thickness toward both ends of the eye.
Abstract:
Apparatus for use with a package compression strapping machine including a batten receiving passageway below a lower pressure platen in adjacent spaced relation thereto and a batten lift mechanism in the passageway for raising a batten from a recessed position in the passageway below the lower pressure platen into engagement with a bottom surface of a compressed package and for holding the batten in a controlled position thereon for subsequent engagement and tensioning of strapping about the batten and compressed package.
Abstract:
A hand-operated nibbling tool for use with sheet material is provided with an elongated frame and with a pistol-type hand grip at its rear end and a downwardly depending trigger-like operating lever forwardly of the hand grip. The operating lever has camming engagement with an elongated punch lever pivoted at one end on the frame adjacent the hand grip and having a punch at its other end which, in cooperation with a die formed in the frame adjacent its forward end, operates to shear consecutive small rectangular pieces from the sheet material. The location of the pivots and the shape of the camming surface are such as to provide ease of operation and also a varying operating speed, if desired.
Abstract:
An anti-friction bearing is made by replacing one or more of the conventional roller elements with TFE or FEP elements of the same size and shape. After a short break-in period, a thin antifriction film or TFE or FEP will transfer onto the races and the other bearing elements and will be maintained throughout the life of the bearing by additional transfer from the fluoroplastic roller elements to preclude the surface coating from wearing through.
Abstract:
An article handling apparatus usable with a conveyor including a lift and a drive which has a single fluid actuated motor to reciprocate the lift, between a rest position in line with the conveyor and an elevated position. The drive includes a disengageable one-way rotary operator which rotates the lift a predetermined angular amount upon its being raised and lowered between an intermediate elevated positon and its extended position.
Abstract:
A rotary output locating and locking device operable for positively locking a rotary output of an air motor operated power tool in a predetermined angular relation to the tool housing and for positioning a torque indicator carried on a motor operated rotary drive, which is interconnected to the rotary output via a torsional spring drive, in a corresponding starting position to condition the tool to be energized for calibrating and setting stall torque under simulated running load conditions.
Abstract:
A convergence cup for use in color kinescopes includes an improved shield structure for magnetically separating the pairs of pole pieces. The one-piece shield is formed from a single metal strip with tabs at its ends by bending it 180* along a lateral line and cutting from the strip a third tab extending from the bend line, and bending the resulting legs 120* outwardly along central lateral lines to form a Y-shaped shield. The onepiece shield is then secured in position inside the cup by spot welding the tabs to the cup wall.
Abstract:
A dispenser for replaceable knife blades has a support member with a shelf portion providing a shelf surface extending generally horizontally and a cover member which is slidable over the shelf portion. The cover member is secured in engagement with the support member and has apertures therein for effecting movement of the uppermost blade outwardly through the side thereof. As the blades are dispensed, the cover member slidably descends relative to the shelf portion.
