The clock movement comprises a perpetual calendar mechanism (1-15), an equation-of-time mechanism (16-19) and a third mechanism (20-23) which is actuated by the first so as to modify the angular position of an equation-of-time cam (16) of the second mechanism, as a function of the number of days in the months. Thus this cam (16) always performs exactly one complete revolution in one year, irrespective of the number of days in the year. The movement is therefore a perpetual calendar movement and ...

The invention relates to a movement simulator having a support frame and a subframe movable relative to the support frame and connected by a variable element. A simple control assembly is electrically connected to the variable element for controlling its length. The transducer assembly having at least one acceleration transducer attached to the variable element supplies and an acceleration signal of a subframe relative to the support frame to the control assembly.

A timepiece movement for driving a plurality of hands, one of which is an hour hand, comprises a power train including a pair of identical, coaxially mounted, independently rotatable gears operatively connected with the hour hand, one of said gears being driven by said power train and the other of said gears being selectively operated manually, with magnetic means normally coupling said gears for simultaneous rotation but permitting adjustment of said manually operable gear relative to the other...

This invention is exemplified by a hammer made in two pieces, a body piece and a lever piece. The hammer is used to return heart cams such as are used in stopwatches and counting devices to the zero position when a button is pressed. The hammer disclosed consists of a pivoted part which coacts with the button and a lever part which is held between the pivoted part and a platen in such a way that it drives the heart cams to zero position when the pivoted lever engages it at one point.

Bimetal instrument movements of the V-pivot type and the pin-pivot type in which the integral upstanding portions of a one-piece frame member support the fulcrum for the movements' pointer means and U-shaped bimetallic structure. Calibration and/or adjustment is effected by forcibly bending the upstanding portions. The instrument movement of the pin-pivot type described is provided with removable pointer means.

In a blow moulding machine of the kind in which an extruder feeds a tubular extrusion into a two-part die, the die subsequently closing and gripping the extrusion and the extruder being retracted to stretch the extrusion for severing between the extruder nozzle and the die, the extruder nozzle is arranged to retract linearly and axially from the die so as to cause the extrusion to be stretched symmetrically and linearly along its axis, thereby resulting in the severed edges of the extrusion bein...

This invention is a mechanical movement for converting reciprocating linear motion to rotary motion. An arm is pivotally connected at one end to a source of reciprocating motion. The opposite end of the arm is connected to a driving member mounted on a rotatable shaft at approximately a 45.degree. angle to the longitudinal axis of the member. As the arm moves in response to the reciprocating motion, corresponding movement of the opposite end of the arm is effected, producing actuation of the dri...

A mechanical movement having a driven body and a driving body set at angles to each other. The driven body provided with teeth about its periphery and the driving body with a circular edge adapted to enter between the teeth and means for its rotation about a central axis. The edge being normally circular but having a separable end adapted to be flexed to either side of the plane of the circle. Means are provided to flex the separable edge during rotation of the driving body.

A device for transforming a rotational movement into a linear movement. The device comprises a retainer and a shaft extending through the retainer which are mounted for movement relative to one another. A plurality of annular bearing members, in the illustrated embodiment, comprising ball bearings, circumscribes the shaft and engages the same at axially spaced locations. The bearings are mounted for tilting movement relative to the shaft. The outer ring of each of the bearing assemblies is suppo...
