A pneumatic fastener driving tool of the hand held gun type having means for positively insuring against accidental firing when the fastener magazine is empty or detached, or when the nosepiece is not pressed against a workpiece. The means comprises a linkage train including an intermediate link carried by the magazine and movable by a first link reciprocably associated with the nosepiece to move a second link associated with the trigger assembly to render the trigger operational for firing the tool. There are locking means associated with the feeder of the fasteners for locking the intermediate link in an inoperative position when the magazine is empty of fasteners.

Magazine interlock for a fastener driving device

A portable gas-fired fastener driving tool in which the tool cannot be operated until the combustion chamber is closed and the combustion chamber cannot be reopened after ignition until the trigger is released. The operation of the trigger is permitted by the actuation of a bottom trip mechanism which controls the movement of a sleeve mechanism that regulates the opening and closing of the combustion chamber. During the driving action, the combustion gases above the piston are evacuated through valved openings in the cylinder adjacent the bottom thereof. The piston contacts a bumper at the bottom of its travel and the difference between the vacuum in the combustion chamber and atmospheric air acts to return the piston to its driving position.

In food-mixing apparatus comprising a driving unit and an arm, a latching and pivoting mechanism is adapted to be latched automatically so as to prevent relative movement of the arm and a console of the driving unit upon pivotal movement of the arm either to a lowered position or a raised position, and so as to prevent relative movement of the arm and the console, except for pivotal movement of the arm, upon pivotal movement of the arm to a pivotal position therebetween. The mechanism is adapted to be unlatched manually so as to permit pivotal movement of the arm from any pivotal position, and so as to permit the arm to be removed from the console upon further movement of the arm from the raised position.

A food mixer having a stand with a mixer head pivotally mounted thereon for mixing foods is disclosed herein. The mixer includes means for cooling a drive assembly by drawing air in through a forward portion of the head and exhausting it out a bottom portion of the stand. The mixer is provided with a locking latch interconnecting the head and the stand in order to mix or knead properly heavy or viscous foods, such as bread dough. A pair of dough hooks, which are adapted to force dough away from the head during kneading, are detachably connectable to the head. A high outer wall turntable is rotatably supported on a base of the stand by a peripheral thrust bearing to provide a stable platform for a mixing bowl. Each mixing bowl used with the mixer has the same diameter bottom and lower contour regardless of bowl volume. A mechanical governor is connected to an electronic control to provide accurate motor speed regulation throughout the range of motor speed operation.
