  • Patent number: 4111389
    Abstract: A column drawing table where the weight is equalized by a gas spring. This gas spring is supported in an elastic receptacle between the column and the pedestal foot, and the column is guided in a hollow pedestal so as to be movable along its length. It can be stopped at an arbitrary position by a fixing brake. A fall safety device, operative completely independently of the fixing brake, prevents the column from unintentionally sinking if the gas pressure in the gas spring should decline or if the fixing brake should be released.

    Abstract: A vertically adjustable pedestal drawing table with a weight balance provided by a gas spring coupled between the pedestal column and the pedestal foot. Adjustable rollers maintain the true vertical orientation of the column. A pedal operated locking brake fixes the vertical position of the column and a safety locking brake arrests sudden undesired dropping of the column and table.

  • Patent number: RE28767
    Abstract: A drawing table having a stand and a board linked to the stand in such a manner as to allow the board to be adjusted in position whereby the weight of the board creates a second moment about the axis opposing the first moment. A compensating means varies the second moment to compensate for variations in the first moment due to changes in the position of the board so that the board is balanced in any position.
