Description:
Abstract:

This invention relates more particularly to a mechanism for operating the reciprocating valves of gas-engines. The mechanism heretofore employed for operating these valves is undesirable, as the same wears unduly and necessitates frequent renewal of the parts.

Claims:

1. A valve mechanism comprising a valve stem having a flat contact-face, a rock-arm having a circular bearing, and an oscillating shifter-block having a circular part turning in said bearing and a fiat contact-face which cooperates with the corresponding flat face of said stem, substantially as set forth.

2. A valve mechanism comprising a reciprocating valve-stem, a shifter-collar secured to said stem and provided with a flat contact face, a rock-arm having a circular bearing of which a peripheral portion is removed, and an oscillating shifter-block having a circular part turning in said bearing and a fiat contact-face on its periphery which cooperates with the contact-face of said collar, substantially as set forth.

3. A valve mechanism comprising a reciprocating valve-stem, a shifter-collar secured to said stem and provided with a fiat contact face, a rock-arm having jaws between which said stem is arranged and each jaw having a circular bearing, and an oscillating shifter block having circular ends which turn in the bearings of said jaws and a flat contact-face on its periphery which cooperates with the flat face said collar, substantially as set forth.

4. A valve mechanism comprising a reciprocating valve-stem, a shifter-collar secured to said stem and provided with a flat contact face, a rock-arm having jaws each of which has a circular bearing, and an oscillating shifter-block having circular ends which turn in the bearings of said jaws, a flat contact face on its periphery which cooperates with the face of said collar and a laterally-opening recess in its central part which receives said stem, substantially as set forth.

5. A valve mechanism comprising a reciprocating valve-stem, a shifter-collar secured to said stem and having a flat transverse contact-face, a rock-arm having a pair of jaws each of which has a circular bearing of, which a peripheral part is removed, and a shifter-block having circular ends which turn in the bearings of said jaws, a flat contact-face on its periphery which projects through the open parts of said bearings into engagement with the contact-face of said collar and a laterally-opening recess between its en ds which receives said valve-stem, substantially as set forth.

6. A valve mechanism comprising a valve stem, a hanger having an open in an arbor having a head at one end and a shank at its opposite end which is seated in said opening and provided with an annular groove, a screw arranged on said hanger and engaging with said groove and a rock-arm for actuating the valve-stem pivoted on said arbor between its head and the hanger, substantially as set forth.

7. A valve mechanism comprising a valve, a stem connected with said valve and having a shoulder and a screw-thread below said shoulder, a threaded shifter-collar which is screwed on the thread of the stem and against the shoulder thereof, and a rock-lever engaging said collar, substantially as set forth.
