Obviously, the counterweight system could be used for other applications. When used in a drafting table of the type including a frame and a table top provided with vertical legs guided for up-and-down movement within the frame, cables are attached to the lower end of the two legs and are trained over a common pulley and attached to said pulley, which is freely rotatably mounted within the frame. A spiral-shape cam member is fixed to one side of the pulley and an additional cable which is attached to the pulley is trained over the cam member and attached at its other end to one end of tension springs, the other end of which is attached to the frame.Type: GrantFiled: September 4, 1980Date of Patent: September 28, 1982Inventor: Joseph L.

Patent number: 4322005Abstract: A corrugated paper display stacker having a plurality of vertically arranged springs and upwardly biased pivoted trays secured to a back panel. A double acting torsion spring having hooks on protruding fingers that are inserted into the fluting of the tray and a stablizing U-shape loop on the other side of the spring maintain each of the trays in a vertical position when not loaded with merchandise. The torsion spring is held to the back panel by securing means in the form of a dowel.Type: GrantFiled: March 27, 1981Date of Patent: March 30, 1982Assignee: DisplaycoInventor: David Robertson

Patent number: 4161233Abstract: A portable tree seat adapted for use with a tree or other generally vertical member is disclosed. The tree seat includes a mounting member or support bracket adapted to fit around the trunk of a tree and a seat platform. The seat platform is pivoted to the mounting member and includes a heat retaining cover on its upper surface to retain body heat. When weight is applied to the seat platform, the mounting member is torqued to a stable position.Type: GrantFiled: December 9, 1977Date of Patent: July 17, 1979Inventor: James A. Wirtz

Patent number: 4156391Abstract: The top of a table such as a drafting table which may be adjustable in its elevation, is counterbalanced by counterbalancing elements exerting an approximately constant balancing force. The counterbalancing elements comprise at least one leaf spring forming a bow inserted between the table top and a counter abutment below the table top so that the leaf spring or springs is biassed to form said bow, whereby the load on the bow has a tendency to cause a lateral flexure of the bow. The arrangement is such, that the downwardly directed force component caused by the weight of the table top and the pressure exerted by the bent leaf spring or springs, are directed opposite to each other.Type: GrantFiled: June 19, 1978Date of Patent: May 29, 1979Assignee: Reppisch-Werke GmbHInventor: Lorenzo Ubezio

Patent number: 4154221Abstract: A tracking system is provided for positioning solar energy collection units to face the sun during daylight hours. The collectors are mounted generally in north-south alignment with rotatable connections to a supporting base. The connections are laterally offset from the center of gravity of the collector. Thus, the weight of the collector ends to rotate the collector about the connection points to bring the center of gravity to the lowest possible point, thereby orienting the collector generally to face the western horizon. A rotation restraint mechanism is provided to prevent the uncontrolled rotation of the collector to a degree coordinated with rotation of the earth relative to the sun, thereby positioning the collector to directly face the sun during daylight hours. A rank of collectors in parallel alignment can be connected for tandem rotation under the control of a single rotation restraining mechanism.Type: GrantFiled: April 21, 1977Date of Patent: May 15, 1979Assignee: American SolarInventor: David H. Nelson

Patent number: 4113057Abstract: A tree stand, seat, or table adapted to be attached to a tree or like vertical column, comprising a board or like planar support member, provided with piercing points adapted to engage the tree, tie-attaching means substantially below said piercing points, and tie means for tying said tie-attaching means against said tree with the seat in vertical position along side the tree. Spring means is interposed between the tie means and the board or between the piercing points and the board so that when the board is rotated up to the horizontal position, the spring means is loaded and forces the piercing points into the tree and tends to cause the seat to return to its initial vertical position along side the tree.Type: GrantFiled: March 24, 1977Date of Patent: September 12, 1978Inventor: Max E. Bessinger

Patent number: RE28767Abstract: 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.Type: GrantFiled: June 19, 1975Date of Patent: April 13, 1976Assignee: Franz Kuhlmann KGInventors: Franz Kuhlmann, Arnold Gundlach, Horst Seiffert
