Abstract: A device for lubricating a rolling bearing. The inventive device comprises a lubricant dispenser (1) connected to the lubricating point of the rolling bearing (7) and a measuring unit (8) allocated to the rolling bearing (7) for detecting the condition of the bearing. The lubricant dispenser (1) comprises a lubricant container with a supply of lubricant (2), a discharge device with an electromotor drive (3) and a control device (4) lined with the measuring device (8). The control device (4) of the lubricant dispenser (1) emits control signals to the electromotor drive (3) at certain intervals prompting it to discharge small amounts of lubricant and changes the discharge times and/or the duration of the discharge intervals if the measuring signal emitted by the measuring unit (8) exceeds a defined value. In this case, a signal for displaying an incipient bearing defect is also emitted.

Abstract: An automatic lubricant dispenser has a lower housing part formed with an outlet, a piston displaceable along an axis in the lower part and forming therein a compartment, a spindle extending along the axis, threaded into the piston, having an upper end above the piston provided with a lower coupling half, and a body of fluent lubricant filling the compartment. An upper housing part removably securable to the lower part holds an electrical motor unit having an output shaft projecting downward at the axis and provided with an upper coupling half axially engageable with the lower coupling half. The coupling halves are axially engageable to rotationally couple the motor output shaft to the spindle so that electrical energization of the motor when the coupling halves are engaged displaces the piston and expresses lubricant from the outlet. A sensor connected to the shaft generates an output after a predetermined angular displacement of the shaft.

Abstract: A lubricating system has a housing formed with an intake passage, a drive shaft extending longitudinally in the housing and carrying a plurality of longitudinally spaced worm gears, and respective pumps juxtaposed with the worm gears in the housing. Each pump has a cylinder fixed in the housing, centered on a respective transverse axis, and forming an intake port connected to the passage and an output port. A cavity-forming piston is rotatable about and reciprocal along the respective transverse axis and a worm wheel on the piston meshes with the respective worm gear. An axially projecting cam ramp on the worm wheel is axially engageable with an abutment on the housing. This abutment can be moved axially and for fixing it in any of a multiplicity of positions for varying axial deflection of the piston. A spring bearing against the piston urges the ramp toward the abutment.

Abstract: A plurality of lubricant dispensers with respective microprocessor controllers are connected to a central microcomputer and can count up the number of revolutions of the respective spindle so that local lubrication at different sites of a machine will satisfy the site requirement even if the machine operation and lubrication have been interrupted. The controller of the dispenser includes a data store responsive to the dispensing time which is reset when a new reservoir is hooked up.

Abstract: An automatic lubricant dispenser has a lower housing part formed with an outlet, a piston displaceable along an axis in the lower part and forming therein a compartment, a spindle extending along the axis, threaded into the piston, having an upper end above the piston provided with a lower coupling half, and a body of fluent lubricant filling the compartment and forming with the spindle, piston, and lower housing part a lower subassembly. An upper housing part securable to the lower part via a screwthread forms an upper subassembly. An insert mainly in the upper housing part forms a battery compartment and carries a motor unit having an output shaft projecting downward therefrom at the axis and provided with an upper coupling half axially engageable with the lower coupling half. The coupling halves are axially engageable to rotationally couple the motor output shaft to the spindle.

Abstract: An umbrella has a foldable canopy, an elongated boom having an end, a joint at the end connected to the canopy and suspending the canopy from the boom end, an upright mast having an upper end, and a fitting having a lower part fixed in the upper mast end, an upper part slidably receiving the boom. A pivot interconnects the upper and lower parts for pivoting of the upper part on the lower part about a horizontal axis between a deployed position with the boom extending transversely of the mast and a storage position with the boom extending generally parallel to the mast. A slide is longitudinally displaceable on the mast between a lower position in which it frees the upper part for pivoting between its storage and deployed positions and an upper position in which it engages the upper part in both the storage and deployed positions and positively retains the upper part therein.

Abstract: A flowable lubricant is metered in pulses to a chain drive under the control of the computer programmed to respond to measurement of the chain drive speed so that, when the speed of the chain drive is below a threshold level above which centrifugal force can cause loss of lubricant, the lubricant can flow in pulses to the chain drive. When, however, the speed of the chain drive rises to the threshold value, the pulse dispenser is blocked and the supply of lubricant pulses is terminated. The lubricant pulses which are not supplied during the interval are stored. When pulse supply of lubrication is restored, the stored lubricant pulses are supplied.
