    Abstract: In a door closer, there are provided a vertical rotatable shaft associated with the rotation of a door through an arm, two cams installed integral with the shaft, an urging device for rotating the door in the closing direction through one of the cams and a cylinder device for braking the door during door closing operation through the other of the cams. Thus, the opening of the door is effected by overcoming the force of the urging device and hence the door can be opened lightly. When the door is released, the force of the urging device is transmitted to the one cam and then to the arm, so that the door can be automatically closed. During door closing operation, the cam surface of the other cam pushes the piston rod of the cylinder device, whereby the rotation of the other cam and hence the rotation of the shaft connected with the other cam are braked, avoiding severe shocks to the door.

    Abstract: A tension spring motor for use in a pintle or cartridge like container is employed to return hinged parts to an initial position after having been rotated to a second position. Door hinges are a typical example where a spring automatically returns the door to closed position after it has been opened. To vary the tension in the spring use is made of a pair of notched members housed within the pintle, one being a fixed member and the other being a movable member attached to the spring and rotatable to different positions of adjustment. A wrench hold in the movable member is accessible from the outside through a hole in the fixed member.

    Abstract: A power tool for applying a rotational force to a spring of a door counterbalancing mechanism. The power tool has a rotatable drive member mounted on a casing carrying a power transmitting structure. The drive member has a slot with an open end for accommodating the shaft of the counterbalancing mechanism. A releasable coupling structure drivably connects the drive member with the collar attached to the spring so that rotation of the drive member will apply rotational force to the spring. A motor connected to the power transmitting structure is operable to rotate the drive member. A socket adapter or pipe adapter can be connected to the drive member so that the power tool is usable to rotate nuts, bolts and pipes.

    Abstract: An adjustable spring loading mechanism for use in controlling the movement of doors and the like. The mechanism includes a cylinder housing and a piston slideable within the housing. A plurality of biasing means are arranged in the housing in engagement with the piston, and apply individual biasing forces to the piston which cooperate to produce a total resultant biasing force. The biasing means are provided with different effective lengths so as to engage with the piston at different positions in the cylinder and thereby vary the total biasing force.

    Abstract: A door having horizontally hinged sections is supported upon reinforced track means for movement between an upright closed position and an open position. A counterbalance mechanism, which is mounted upon the wall above the opening, is connected to the door to counteract gravity. The counterbalance springs are connected to fusible link means which melts at a predetermined temperature and thereby reduces the tension on the springs so that the door will close under the force of gravity. Governor means is rendered operative when the fusible link is ruptured to control the closing movement of the door.
