The outer frame is adapted for moving the seal toward the jamb and the outer and inner frames are pivotally connected so as to be able to pivot relative to one another about a longitudinal pivot axis.

Abstract: Apparatus for boring a hole from an inside of a tube outwardly perpendicular to a longitudinal axis of the tube comprises a drill shoe having a longitudinal axis and being positionable in the tube, the shoe having an inlet, an outlet perpendicular to the shoe longitudinal axis and a passageway connecting the inlet and outlet, a torsional load transmitting element having no torsional flexibility in relation to its bending flexibility, having a longitudinal axis and being disposed in the passageway, the torsional load transmitting element being movable relative to itself with no resistance about first and second perpendicular axes both of which are perpendicular to the longitudinal axis of the torsional load transmitting element, a hole saw connected to one end of the torsional load transmitting element and a motor rotatably connected to the other end of the torsional load transmitting element.

Abstract: A device for establishing a reference datum of a wheeled vehicle comprises a first element operably rotatably mounted to a hub of an axle of the vehicle, the first element having a first axis of rotation, a second element having one end rotatably mounted to the first element so as to have a second axis of rotation perpendicular to the first axis of rotation of the first element, and a laser mounted to the other end of the second element. The laser is oriented relative to the second element so as to project a laser plane either parallel to a longitudinal axis of the second element to thereby establish a vertical datum for the vehicle, or perpendicular to the longitudinal axis of the second element to thereby establish a horizontal datum for the vehicle.

Abstract: An apparatus for drying wet roadway surfaces, and more particularly, paved race tracks. The drying device has a rectangular, box-shaped housing with first and second chambers. The first or leading chamber has a first drip pan for collecting water. At least one brush is rotatably mounted in the first chamber such that the longitudinal axis of the brush is oriented transversely to the device's direction of travel when removing water. The brush is adapted to contact the surface so as to collect water in the brush as the brush rotates. The brush is also adapted to contact the first drip pan so as to dislodge the collected water in the brush and deposit the water into the drip pan. First and second squeegees are mounted respectively to the first and second chambers for diverting water away from the surface over which the apparatus is traversing. Finally, a blower is mounted atop the housing for forcing air into the second chamber for evaporating water on the surface not already collected by the brush.

Abstract: A coke oven door comprises a door frame, a plate mounted so as to be freely movable relative to the door frame within limits and a seal operatively mounted to the plate and positioned around the periphery of the frame for effecting sealing against the jamb of a coke oven. In a preferred form, the door comprises a first plate mounted so as to be freely movable relative to the door frame within limits and a second plate mounted to the first plate, having a seal mounted around the periphery thereof and having refractory plugs mounted thereto. Force applying members are mounted around the periphery of the door frame and are selectively adjustable to contact and move the first plate. Force applying members are mounted around the periphery of the first plate and are selectively adjustable to contact and move the seal. Angle sections mounted to the door frame and retainer clips mounted to the first plate cooperate to limit movement of the first plate.

Abstract: A coke oven door for placement against a door jamb of a coke oven comprises a segmented door body and plurality of toggle mechanisms coupled to the door at the juncture of each segment. The toggle mechanisms include inner and outer toggle links pivotally connected by an intermediate pivot shaft and the links are pivotable between an extended length and a shortened length. Inner ends of the toggle mechanism are coupled to the segmented door body and outer ends of the toggle mechanisms are coupled to a flexible latch tension bar. The latch tension bar engages latch hooks connected to the door jamb and vertical movement of a latch actuator rod coupled to the intermediate pivot shaft moves the toggle mechanisms to an extended position to flex the latch tension bars and force the door body against the door jamb to seal the coke oven.

Abstract: A coke oven door extractor is mounted on the rail car and includes door engaging supports movable in individually differing amounts relative to a plane parallel to and including the door jamb and a door jamb height axis of symmetry and movable vertically, allowing the door extractor to compensate for front-to-back tilting and side-to-side leaning of the coke oven door jamb due to thermal distortion of the battery and variations in individual door heights. The extractor includes a first frame pivotally mounted to the car, a second frame horizontally translatably mounted to the first frame, and a third frame vertically translatably and pivotally mounted to the second frame, with the third frame including the door supports.

Abstract: A coke oven rail car with a drive control system for positioning the car and for spotting the functional equipment carried by the car. A sensor determines the relative position of the car with respect to a selected oven in a coke oven battery. The car includes a first drive for effecting gross movement of the car along the rails and gross positioning of the car relative to the selected oven. The car further includes a second automatically controlled drive for effecting fine movement of the caw along the rails and fine positioning of the car relative to the selected oven. In one embodiment the first drive is manually controlled, while in another embodiment the first drive is automatically controlled. The second automatically controlled drive can take the form of one or two disk clutch type mechanisms or a clutch band type mechanism.

Abstract: Coke oven doors and more particularly coke oven doors having a unique and novel spring arrangement for maintaining the knife edge of the sealing element in sealed relation to the face of the coke oven door jamb, an improved sealing arrangement at the leveler door, scalloped cutouts in the main frame components to increase efficiency of heat dissipation, a manual adjustment structure incorporated into the main door frame to provide more positive and controlled flexibility of the main door frame and the provision of cuts in the door frame and the manner in which the diaphragm plate is connected to the refractory to provide space for the door frame to flex when adjustments are made.

Abstract: A coke oven door has a mainframe, a diaphragm plate mounted on the mainframe, a seal mounted peripherally on the diaphragm plate, and plungers mounted peripherally on the mainframe for applying adjusting force to the seal. The seal is adapted for angular contact with a door jamb, and is backed by individual leaf springs arranged in end-to-end relation which are operable to provide rigidity to the seal when the seal is in contact with the jamb. The seal is locally adjustable with the plungers. The mainframe includes a pair of generally parallel side plates having slots along their lengths and a turnbuckle spanning each slot. The turnbuckles provide for flexing the mainframe into a desired configuration for initial adjustment of the door to a door jamb.

Abstract: A coke over door jamb cleaner utilizing a unique supporting arrangement, scraper-type cleaning elements and a floor or hearth cleaning tool for effectively cleaning the sealing surfaces of a coke oven door jamb and the floor or hearth of the coke oven adjacent the door.

Abstract: A retrofit coke oven door seal to replace existing coke oven door seals that have become ineffective due to normal use. The retrofit coke oven door seal includes a leaf spring and seal arrangement and a unique mounting structure to enable the existing seal on a coke oven door to be easily removed and replaced by the present invention without modification of alteration to the door body or the existing refractories thus making improvements (in emission control) on existing doors by using a relatively simple structure which is cost effective. The retrofit seal for coke oven doors includes a mounting structure attached to the periphery of the diaphragm plate normally provided on a coke oven door together with fastening devices securing a leaf spring and seal assembly in a manner to enable easy removal and replacement thereof if necessary.
