Abstract: A support device for bound materials, such as a notebook binder holding pages of computer software documentation, holds the bound materials in two distinct positions. In a first position, front and back covers, along free edges thereof, are received by slots in the support device which hold the front and back covers in a substantially parallel position to each other. The support device is otherwise essentially open so that the entire spine and substantially all of the front and back covers are easily seen. In a second position, one side of the support device includes a pair of angled notches formed therein which receive lower free edges of the front and back covers. Turning the support device onto its other side allows the user of the device to place the binder in the second position, supported in the notches in an open, raised or easel position for easy access and use.

Abstract: A module for selectively deploying a reciprocable tool, such as a hole punch, which is reciprocated by a press. The module includes a housing which is attached to the ram of the press. The housing retains a reciprocable tool within a bore for movement between an extended position and a retracted position. The reciprocable tool is connected to the housing by means of a telescopic linkage comprising a cone clutch having resilient fingers that selectively grip a pin. The housing includes a conical surface which engages beveled portions of the resilient fingers holding them in a closed position. A spring biases the cone clutch to its closed or gripping position unless air pressure is supplied to an air chamber which counteracts the biasing force of the spring to open the resilient fingers. When the resilient fingers are open, a shifting means comprising a spring, or alternatively a solenoid, is effective to shift the pin between an extended position and a retracted position within the cone clutch.

Abstract: A trough conveyor receives small logs from a deck to form a bundle and conveys the bundled logs lengthwise to a discharge end. The log bundle is transported intermittently to project sections of the log bundle successively beyond the discharge end of the trough conveyor, which sections are cut off to form batches of bolts by vertically reciprocable twin saw cutoff mechanism. After a cutting operation, the saws may be swung away from each other to clear the trough conveyor while the saws are being raised and, during such raising movement, the trough conveyor may be powered to feed the log bundle lengthwise to project the next bolt-making increment of the logs beyond the cutoff mechanism.
