With Bearing Shield Patents (Class 177/179)
  • Patent number: 9995620
    Abstract: This disclosure provides a combination scale including a dispersing feeder, linear feeders, a plurality of hoppers, and a collector. The dispersing feeder and linear feeders are respectively disposed in upper parts of a center base of the combination scale to disperse and deliver outwardly articles received therein. The hoppers are removably mountable to an outer periphery of the center base to hold and discharge the articles. The collector collects the articles discharged from the hoppers on a central side of the center base and discharges the collected articles. The collector constitutes a collecting and discharging channel for the articles to be collected and discharged. The combination scale further includes a shielding tool configured to block liquid that drops from the center base downward into the collecting and discharging channel.

  • Patent number: 5801338
    Abstract: A platform weighing scale includes a base with vertical corner stands and a weight supporting platform including depending corner bearings. A weight sensing apparatus is supported on the base corner stands and supports the weight supporting platform so that it is moveable relative to the base. A weight sensing mechanism is responsive to movement of the platform for operating a weight indicating device. The weight sensing mechanism includes a plate operatively associated with the weight indicating device. A pair of primary levers are secured at one end to the plate and diverge therefrom relative to a longitudinal centerline and define a select angle therebetween. Each primary lever includes an upper notch receiving one of the corner bearings and a lower notch receiving one of the corner stands so that movement of the platform causes pivotal movement of the levers to move the plate.

  • Patent number: 4957177
    Abstract: A dual beam moment-insensitive load cell is hermetically sealed in a bellows or partial-bellows enclosure. The enclosure may have convolutions over substantially its entire length which permits it to flex easily in the direction of load cell bending. The enclosure is made resistant to elastic buckling under torsional forces produced by off-center loading of the load cell by one or more rods spaced circumferentially about the enclosure and connecting together a number of the convolutions after the convolutions are aligned. The alignment and torsional stiffening resist elastic buckling of the enclosure and resulting error in the output of the load cell. Another form of enclosure has one or more convolutions at each end and joined by a relatively straight, non-convoluted wall which itself is resistant to torsional elastic buckling. The resistance of the wall to torsional elastic buckling can be increased by increasing its thickness uniformly or by applying stiffener rods thereto.

  • Patent number: 4729443
    Abstract: A protection and secondary checking system for a weighing scale having a scale platform which is spaced peripherally from a support to form an intervening space. The protection and secondary checking system is supported on both the scale platform and the support but is not connected to either, and includes an elongate resilient body having a central web which extends into the intervening space to orient the body and provide platform checking. A cover and mounting section extends laterally from one longitudinal edge of the web and rests on both the platform and support.

  • Patent number: 4526246
    Abstract: Water-resistant weighing apparatus comprising a load cell having a plate, one or more beams with fixed ends connected to the plate and strain sensing means on the beams. A platter is supported by the beams for receiving a load applied between the plate and the beam. The platter encloses the top and sides of the load cell and a shield is connected to the bottom of the platter and encloses the bottom of the load cell. A gasket is provided to seal the interface between the platter and the shield. A plurality of feet are provided for contact with a support surface. Bushings extend through the shield and connect the plate to the feet and sealing boots are provided to seal the openings in the shield for the bushings. The shield may include a vent to expose the load cell to atmospheric pressure and a sub-base plate may be provided to deflect moisture from the bottom of the shield and the vent.

  • Patent number: 4469147
    Abstract: A novel seal, weighing tube and filling tube for a weighing feed system spout advantageously used for simultaneously filling and weighing bags with particulate material. The seal is an annularly shaped non-resilient member installed between the exit ends of the tubes to prevent accumulation of particulate material which would otherwise adversely affect the accuracy of the weight measurement. The seal is made of a non-influencing material such as dacron, silk, cotton or the like to preclude weight measurement inaccuracy. The weighing and filling tubes are provided with unique seal retainer rings which provide for retention of the seal by means of an effective gathering such as a drawstring on the filling tube and an O-ring on the weighing tube. An optional tool is disclosed for facilitating seal installation.

  • Patent number: 4453607
    Abstract: The base of a weigh scale includes openings in the bottom thereof at each corner. The base is raised above a supporting surface by way of rigid foot members aligned with the openings in the corners of the base. Load cells in the form of deflection beams each having one of their ends fixed to the base while their other end contacts upper surfaces of their respective foot members. Damage to the load cells by side shock loads is eliminated by way of resilient coupling members connected between the foot members and the base.

  • Patent number: 4396079
    Abstract: A low profile scale utilizes four strain gage-based sensing beams which are isolated from mechanically or thermally-induced distortions on the weighing platform by means of interposed elastic elements. The platform is capable of moving upwardly relative to the sensing elements without transmitting any load thereto. The platform cooperates with a floating lower enclosure system to essentially seal the mechanism so that it is splash proof and washable as required for use in the food industry. Adjustable overload stops channel excess forces around the sensing beams to protect them from damage.

  • Patent number: 4280577
    Abstract: Weighing apparatus of the electromagnetic load compensation type is disclosed including a pivoted transmission lever that connects the compensation coil for movement relative to the stationary permanent magnet field in accordance with the displacement of the load receiving assembly from its initial no-load position, characterized in that the transmission lever is connected with the load receiving assembly via a flexible bearing contained within a hollow coupling part of the load receiving assembly, thereby protecting the bearing against the deleterious influence produced by the different heating rates of the various structural components. By protecting the flexible bearing against component-generated heat as well as extreme variations in ambient temperature, the zero or no-load operating point of the weighing apparatus is protected against temperature-produced errors.

  • Patent number: 4253534
    Abstract: A weight scale is made splash resistant from being splashed by liquids. Means is also disclosed for making the weight scale vapor resistant. The scale includes a housing on a column on a base and a force-to-electrical output transducer is mounted enclosed within the upper housing. A rod is enclosed within the column and is moved longitudinally therewithin by being connected to a lever system connected to the pan or platform on which the weight is received. The rod acts on the transducer and an electronic circuit provides an indication of the weight on an indicator also in the housing. Liquid splash-resistant means is positioned between the bottom of the base and the transducer within the housing for splash-resistant protection of this transducer. The foregoing abstract is merely a resume of one general application, is not a complete discussion of all principles of operation or applications, and is not to be construed as a limitation on the scope of the claimed subject matter.
