| 161 | Vacuum control valve for automotive heating and airconditioning systems | US455200 | 1983-01-03 | US4448390A | 1984-05-15 | Raymond T. Halstead; Charles E. Black, III |
| A vacuum control valve comprising a body having a valve surface with a plurality of valve ports extending through the body from such surface, a soft resilient valve member having a control surface slidable along the valve surface and formed with passage means for selectively establishing communication with the valve ports, a movable carriage for receiving and supporting the valve member, and means for moving the carriage along a path substantially parallel with the valve surface, the soft resilient valve member having a soft resilient compressible rear portion formed integrally with such valve member on the opposite side thereof from the control surface, the valve member being confined between the carriage and the valve surface with such soft resilient compressible rear portion in a compressed condition for exerting resilient pressure between the control surface of the valve member and the valve surface of the body, the soft resilient compressible rear portion comprising a pattern of fins alternating with recesses on the valve member, such fins engaging the carriage. | ||||||
| 162 | Pedal mounted switching assembly | US337147 | 1982-01-05 | US4403123A | 1983-09-06 | Thompson Shek |
| A switching assembly for mounting on a pedal has a flat shaped switch actuator constrained to move with a single degree of freedom in a plane parallel to the pedal face. A pressure member at the front of the pedal receives a control force from an operator and as it moves toward the pedal face moves the switch actuator through a cam linkage. The cam linkage includes cam surface extending close to the periphery of the pressure member so that the cam action is effective irrespective of the area of the pressure member pressed by an operator. The switching assembly is effective in changing switch settings of a plurality of switches in a predetermined order as the pedal is pressed irrespective of the point of application of control force to the pressure member. | ||||||

| A vacuum control valve, comprising a wall having a vacuum supply port and a utilization port therein, a valve member movable along such wall, and means guiding the valve member for movement along a predetermined path along such wall, such valve member having a sealing member with sealing enclosure means for selectively producing communication between such ports, each of such ports comprising an opening with a tapered portion extending into such wall at the intersection between such opening and such wall to avoid the formation of any burr at such intersection. | ||||||
| 164 | Fluid control switches | US73011 | 1979-09-06 | US4291725A | 1981-09-29 | Andrew F. Raab; Raymond T. Halsted |
| A combined electrical and fluid control switch is disclosed, comprising a casing, at least one operating carriage movable in the casing, and valve means in the casing and operable by the movement of the carriage. The valve means may comprise a valve wall along which a control member is movable. The valve wall is formed with at least one vacuum supply port and at least one vacuum utilization port. The control member includes a sealing member having first and second sealing dam enclosures which provide a double seal to prevent leakage between the atmosphere and the vacuum supply port as the control member is moved between a first position in which the support port and the utilization port are connected together, and a second position in which the utilization port is connected to the atmosphere. Each port preferably has a tapered portion at the intersection between the port and the valve wall. | ||||||
| 165 | Gas valve-switch assembly | US933174 | 1978-08-14 | US4249047A | 1981-02-03 | Norman M. Huff; George T. Horodeck |
| A detachable gas valve--switch assembly intended especially for a domestic gas range, in which the valve includes a body has a control element movable by a rotatable valve stem and the switch having a contact operating means rotatable by the stem. The switch is constructed and arranged for releasable retention in a position closely adjacent the front end of a gas valve. It is also apertured for mounting on the stem and for movement in one direction axially of the stem to said position and in the opposite direction for removal from said position. The switch and valve include axially extending resiliently engageable quick attach-detach coupling structure of novel construction for releasably and firmly retaining said switch axially in said position upon movement in one direction into said position, and includes also switch contact operating means engageable with said driving portion of said stem when in said position. Movement in the opposite direction disengages the switch retention and contact operating means. The coupling structure is novel in and of itself. | ||||||
| 166 | Combined electrical switch and fluid power control device | US761772 | 1977-01-24 | US4126153A | 1978-11-21 | Andrew F. Raab |
| The disclosed combined fluid power and electrical control device comprises a casing having an operating lever extending through an opening in the casing between the front and rear sides thereof, means at the rear of the casing pivotally supporting the rear portion of the lever so that it is swingable in the opening, the lever having a front manually operable portion at the front of the casing, and fluid power and electrical control means in the casing and operatively connected to the lever for operation in response to swinging movement thereof. Preferably, the control device includes a carriage movable in the casing, mechanical coupling means between the lever and the carriage for moving the carriage in response to swinging movement of the lever, electrical switching means operable by movement of the carriage, and fluid power control valve means operable by the carriage. The switching means may include fixed electrical contact means mounted on the rear wall of a lamp housing secured within the casing. A contactor is preferably mounted on the carriage for selective engagement with the fixed contact means. The carriage may comprise camming means for moving a slide valve member relative to fluid ports in the casing. Cooperative detent means may be provided on the lever and one side wall of the lamp housing which may be secured in the casing by ratchet latching teeth adapted to interlock with abutment elements. The control device may include a second lever having a cam plate portion with a lateral throw for laterally moving a second slide valve member. | ||||||
| 167 | Switch-valve assembly having rotatable operating mechanism with latch | US787195 | 1977-04-13 | US4123633A | 1978-10-31 | Joe M. Stevens; Elmer D. Porter |
| A valve and switch assembly having a rotatably movable actuating mechanism in common. The actuating mechanism acts to actuate both devices when rotated. A latch mechanism, however, prevents rotation of the actuating mechanism when it is rotated to a first position. The latch is deactuated by axially depressing or collapsing the actuating mechanism and then rotating it. An additional unique feature lies in the switch assembly in which the switch contacts are electrically insulated from the actuating mechanism. | ||||||
| 168 | Switch assembly for gas tap assembly having cam operated leaf spring contacts and split housing cam detent stop | US580084 | 1975-05-22 | US3971904A | 1976-07-27 | William Edward Ward |
| An ignition switch for the selective ignition of a gas tap assembly that is controlled by a rotatable gas tap spindle is disclosed. The switch has an aperture which receives the gas tap spindle. Opening and closing of the gas tap is achieved by rotation of the spindle. Rotation of the spindle causes rotation of a cam in the aperture of the switch to control the making and breaking of a pair of electrical contacts. The contacts have relatively thick terminal portions that are secured in the housing with their outer ends extending into openings which receive insulated sockets. The contact members are L-shaped and have relatively thin contact portions which are positioned so that one portion overlies the other and both of them overlie the rotatable cam. | ||||||
