VALVE FOR REGENERATIVE FURNACES.

SPECIFICATION forming part of Letters Patent No. 684,102, eat-a October 8, 1901. Application filed February 12, 1901. Serial No. 47,065. (No model.)

Each Valve 4, it will be the other end of the red. A handle is provided for rotating the collar 20. It will thus be seen that when the wheel 15 is rotated to reverse the valves one of the arms 17 or 18 comes beneath the abutment 20 and is engaged thereby, as shown to the right of Fig. 3. A rotation of the cam 26 forces the collar 23, with its abutment 20, downward, thereby applying powerful pressure to the arm and edecting a tight joint of the valve which has been drawn upwardly. By the threaded arrangement of the parts described the height of the abutment may be very accurately adjusted.

In order that the arms may be readily disengaged from the abutments, they are made of sufficient flexibility to allow them to be sprung laterally to carry the engaging portions from under the abutments, while being perfectly rigid under strains exerted circumferentiallyof the wheel by reason of the metal being set edgewise.

Having thus described our invention, what we claim is- 1. A valve for regenerative and like furnaces comprising a valve chamber or casing having internal upper and lower seats, a hollow valve-disk having faces for cooperating with said seats, a tubular valve-stem screwed completely through said disk, a nut or cap closing the lower end of said tube, said tube having openings communicating with the interior of the valve, and water-circulating pipes cooperating with' said tubular stem, substantially as described.

2. A valve for regenerative and like furnaces, comprising a valve-casing having upper and lower internal valve-seats, a hollow valve arranged to cooperate therewith, a tubular valve-stem screwed completely through said valve and having openings communicating with the bottom portion of the valve, a cap or nut closing the lower end of the stem and abutting against the lower side of the valve, a second nut screwed upon said tube and abutting against the upper side, a pipe within and of less diameter than said tube and forming an annular space, and water flow and return pipes connecting with said pipe and said annular space, substantially as de scribed.

3. In a regenerative or like furnace, the combination with the two alternately-operating valves, of a hand-wheel or pulley, a cable connected with the valves and passing over said pulley, and means for applying extra pressure to said hand-wheel at each extremity of its movement to effect a tight closing of the valves, substantially as described.

4. In combination, the alternately-operating valves, a pulley-wheel, a cable passing over the same and connected to the valves, arms carried by said wheel, movable abutments adapted to engage said arms at the extremities of the movement of the Wheel, and cams journaled in proximity to said abutments for moving the same, substantially as described.

5. In combination with the alternately-operating valves, a pulley-wheel, a cable passing around the same and connected to the valves, a pair of arms radiating from the pulley, pulley-wheel posts located on opposite sides of the pulleyqvheel, abutments carried by the pulley-posts for engaging the arms, springs bearing on said abutments and cams located in proximity to the abutments for depressing said abutments, substantially as described.

In testimony whereof we affix our signatures in presence of two witnesses.
