Patent number: 7530576Abstract: A non-impact keyless chuck suitable for use with manual or powered drivers is disclosed. The chuck comprises a body which carries a rotatable split nut having a relatively fine thread and a plurality of slidable jaws, which may be identical, driven by the rotatable nut. An anti-friction bearing is disposed between the rotatable nut and a bearing thrust ring mounted on the body. A clutch or torque limiting mechanism is provided to limit the tightening torque to a predetermined value while the loosening torque may be limited or unlimited. The front sleeve, and rear sleeve, if used, may be formed from a structural plastic to reduce manufacturing costs. A relatively soft elastomeric grip boot may be placed on the front sleeve to improve the grip and temporarily restrain and center the tool during chuck tightening or loosening operations. A relatively soft elastomeric grip boot may also be placed on the rear sleeve, if used.Type: GrantFiled: May 15, 2006Date of Patent: May 12, 2009Assignee: Jacobs Chuck Manufacturing CompanyInventors: Robert O.

Patent number: 4549444Abstract: A locking gear drive for a protective roll-type shutter or awning device. The gear drive comprises, for example, a housing, a driveshaft coupled to a driving gear, a driven gear meshing with the driving gear and a driven shaft coupled to the driven gear. A socket is mounted at one end of a longitudinally displaceable driveshaft and the socket is slidably disposed within an end cap affixed to the gear drive housing. A plurality of pin-like projections, acting as locking members, are provided around the exterior periphery of the socket. A plurality of interlocking members for engaging the pin-like projections are provided in the form of bores disposed in an end wall of the end cap. A compression spring disposed around the driveshaft and between the gear drive housing and socket urges the locking members and interlocking members into engagement. Inter-engagement of the pin-like projections and bores holds the driveshaft against rotation.Type: GrantFiled: September 27, 1982Date of Patent: October 29, 1985Assignee: Security Shutter Corp.Inventor: William F. Forquer

Patent number: 4519434Abstract: A winding mechanism for rolling and unrolling an articulated shutter curtain, the winding mechanism comprising a tubular drum with a plurality of integral, spaced-apart arms protruding from its exterior surface. The shutter curtain is attached to one of the arms such that rotation of the tubular drum rolls up the curtain from an extended position or rolls down the curtain from a rolled-up position. More particularly, each arm is alternatively provided at one end with either a rod-like or socket-like projection extending along an edge thereof for slidable interconnection with the rod-like or socket-like projection extending along an edge of the top slat of the shutter curtain. In addition, each arm portion is provided with an arcuate land portion for supporting the shutter in a rolled-up fashion. The tubular drum from which the arms protrude is formed with two half cylindrical elongated members which are slidably engaged by longitudinal bent-over interlocking portions disposed along each edge of the members.Type: GrantFiled: November 19, 1982Date of Patent: May 28, 1985Assignee: Security Shutter CorporationInventor: William F.

Patent number: 4503899Abstract: A locking mechanism for a gear drive such as the gear drive of a roll-type shutter or awning. One of the gear shafts, preferably the driving gear shaft, is rotatably supported such as to be longitudinally displaceable, and carries at its free end a transverse pin. A stationary member is provided with radial grooves engageable by the projecting end of the pin when the shaft is longitudinally displaced under the action of a coil spring. The gear is coupled to the shaft by a pin transversely disposed through the shaft and projecting in longitudinal grooves formed in a portion of the gear. The locking mechanism is unlocked by introducing the end of a crank handle into a coupling socket mounted on the other end of the shaft, and applying longitudinal pressure with the crank handle, such as to disengage the locking mechanism prior to hand-driving the shaft in rotation by way of the crank handle.Type: GrantFiled: March 29, 1982Date of Patent: March 12, 1985Assignee: Security Shutter Corp.Inventor: William F. Forquer

Patent number: 4422493Abstract: A support member for the end of a rotatable shaft for winding and unwinding a curtain of articulated slats forming a roll-type shutter or awning. The support member is made of a pair of interlocked, L-shaped plates forming a box-like structure open at both ends. A bushing, through which is passed the end of the rotatable shaft, is journalled through one of the L-shaped plates and is held in position by a U-shaped saddle member. The support member is converted to a gear drive by replacing the bushing with a worm wheel and mounting in the U-shaped saddle member a worm gear meshing with the worm wheel. The worm gear is mounted on, or made integral with, a drive shaft. The U-shaped saddle member is arranged to be mounted in any one of a plurality of positions within the box-like enclosure so as to provide several possible orientations for the drive shaft.Type: GrantFiled: December 16, 1981Date of Patent: December 27, 1983Assignee: Security Shutter Corp.Inventor: William F.
