Patent number: 4250759Abstract: A digital readout gauge is disclosed which, for example, may be a tire pressure gauge which is mounted in a small portable housing. A pressure chamber is formed within the housing with a valve core deflator mounted within the housing to depress the core of a standard tire valve and permit the air pressure within the tire to be introduced into the chamber. A wall of the chamber is movable with changes of pressure and a piezoelectric crystal transducer or strain gauge transducer is mounted to be stressed in accordance with movement of this wall to develop an analog voltage in accordance with the air pressure. An electrical circuit is contained within the housing and energizable by a battery carried within the housing. A power switch is actuated to an on condition by movement of the gauge onto the tire valve to energize the electrical circuit with the analog voltage passed to an analog-to-digital converter and then to a digital readout display to display the digital value of the air pressure within the tire.Type: GrantFiled: November 21, 1979Date of Patent: February 17, 1981Assignee: Scovill Manufacturing CompanyInventors: Otto Z. Vago, Frank S. Irlinger

Patent number: 4189855Abstract: Ready light circuit is provided comprising a simple third switch blade added to standard thermostat two-blade switch in electric iron. Light is activated when bimetallic element of switch drives third blade into engagement with other blade as iron reaches set temperature. Light stays illuminated as long as main contacts of standard-type blades remain open. When thermostat calls for more heat, light in circuit which is across main contacts, is shorted out.Type: GrantFiled: June 20, 1978Date of Patent: February 26, 1980Assignee: Scovill Manufacturing CompanyInventor: George W. Robinson

Patent number: 4183563Abstract: A panic-proof lockset includes a deadbolt and a spring latch. An interior escutcheon supports a knob for operating the spring latch and a second knob for operating the deadbolt. A crank is coupled to the second knob and a slide member is adapted to turn the crank either selectively clockwise or counterclockwise to a position generally corresponding to the open position of the deadbolt. The slide is in tension when acting on the crank to turn the crank to a position generally corresponding to the open position of the deadbolt. A cam means is provided for moving the slide member in response to rotary motion of the knob whereby the deadbolt and the spring latch are simultaneously retracted by turning the knob. This construction enables a user to rotate one knob to simultaneously retract the deadbolt and the spring latch, thereby providing easy exit in a panic situation.Type: GrantFiled: November 25, 1977Date of Patent: January 15, 1980Assignee: Scovill Manufacturing CompanyInventor: William Stevens

Patent number: 4161659Abstract: A magnetic proximity sensing apparatus for sensing ferro-magnetic objects is especially well adapted for use with fluid cylinders having pistons formed from magnetically attracted material. The apparatus includes a magnetic actuator responsive to the proximity of the fluid cylinder piston or other ferro-magnetic object which closes a switch and enables electrical circuitry for controlling fluid valves or other apparatus. A reed switch mounted within a hollow, cylindrical, permanent magnet has a separate pole piece secured at one end of the reed switch. The proximity of a ferro-magnetic object changes the flux within the magnet, closing the reed switch. The circuitry is solid state and includes a silicon controlled rectifier acting as a gated switch for completing the circuit.Type: GrantFiled: June 9, 1978Date of Patent: July 17, 1979Assignee: Scovill Manufacturing CompanyInventor: Keith Jacob

Patent number: 4144738Abstract: Toggle action hand-setting tool includes special cam surface on toggle parts to intensify setting pressure during the end of closing travel when greatest mechanical advantage is needed. Readily accessible spring means and special mounting means for fastener-part holders are features. Frame may be designed to yield slightly to avoid breakage which might otherwise result if device is used with oversize fabric.Type: GrantFiled: October 11, 1977Date of Patent: March 20, 1979Assignee: Scovill Manufacturing CompanyInventors: Walter H. Dziura, Robert B. Kendall

Patent number: 4055876Abstract: A slide fastener slider has body and diamond preferably of molded plastic parts. The parts are held together in snapfastener fashion. Typically, the slider body carries a head and the diamond an opening or socket. Molded integrally with the diamond is an arching locking arm and a pull tab is provided preferably formed of a pair of cords with spaced crosspieces. The tab is provided with an anchoring end adapted to be trapped under inward flanges at the top of the socket opening, one of the crosspieces being disposed under the locking arm to raise the arm during the pulling of the pull tab. The aforementioned anchoring end prevents overtaxing the locking arm, absorbing the pulling force beyond a preset limited amount borne by the arm.Type: GrantFiled: June 7, 1976Date of Patent: November 1, 1977Assignee: Scovill Manufacturing CompanyInventors: Walter Thomas Ackermann, Jeremias Anthony Martins
