(01. 251-10) '7 The invention relates to valves of the. general type having a rock shaft, an'arm secured to said rock shaft, and a valve secured to said armfor cooperation with a- valve seat, and while it is’ 5 intended primarily for actuation by a gasometer to control the feeding of natural or_manufactured gas to a gas engine, it is usable also for various other purposes. , , l 7 projecting bearing necks t5 and I6 having axially alined bearing openings I1, the axes of which are parallel with the ?at face J3. A rock shaft I8 is mounted in the bearing openings ll‘ and projects beyond the neck it for connection with 5 suitable operating means, a portion of which is shown at H). .The outer end of the neck I5 is provided with a threaded cap 20 to be ?lled with. The principal object of the invention is to pro- , lubricant, and the outer‘ end of the neck It is 10 videa simple, inexpensive and generally improved equipped with, astu?ing box 2!.

The rock shaft I8 extends across the recess 14 the rock shaft, arm and‘ valve are carried by a second block detachably secured to said one block. and an arm, 231's secured to the recess-spanning 15 Thus, upon release of the securing means,v said second block and the parts carried thereby are portion of‘said rock shaft, a set screw 24 being 15 preferably’ employed in securing said arm to said removable as, a single unit from said one ‘block rock shaft. This arm projects out of the recess without disturbing the pipe connections, both the - M and beyond the side 53 of the block l2, and valve and the seat being readily accessible for its projecting end is provided with'a valve 25. 20 making repairs or for replacement when said ,This valve is preferably in the form of a disk of second block is removed; A further object is to provide a valve of such leather‘, rubber or any other suitable material, 20 detachably secured to the arm 23 by means of a.

Whenever repairs are necessary, for instance, 40, ' The numeral 5 on the drawing denotes a onepiece metal block having a ?at side 6 and a recess i 1 opening through said ?at side, the ends‘ of said , grinding of the seat l0 .or replacement of the valve 2-5, the cap screws 28 are removed, where block being provided with threaded openings 8 are bodily removable as a single unit fromtthe 45 and 9 for engagement with pipes. One-wall of the recess l is at right angles to the axes of these openings and is provided with a. valve seat’ l0 surrounding 'one of said openings' At suitable points, the block 5 is provided with threaded '7 ' 50 openings H for a purpose to appear. A second block I2 is provided, preferably in the nature of a thick plate, said block l2 having , ings Ell-and threaded into said openings l I to sides in the novel subject. matter hereinafter described and claimed, description being accom30 plished by reference to the ‘accompanying, draw, . cap screws 28 being passed through these open~ With the foregoing in View, the invention re- ing. . The block I2 is provided with openings'Z'I for alinement'with the openings H of the block 5, 25 upon the block i2 and all parts carried thereby block 5, leaving the latter connected to the-pipes. 45 ' With the two blocks thus disconnected from each other, both the valve and the seat are readily accessible'for inspection, repair, replacement or the like. ' ‘ ' From the foregoing; taken in connection with’ 50 the accompanying drawing, it will be seen that ,I have made novel provision for carrying out the a flat side l3 and a recess l4 opening through 1_ objects of the invention, and while the details said flat‘ side.
