As will be evidenttto those skilled in the. l

art, my invention permits of various modifications without departing from the spirit thereof or the scope of the appended claims..

What E claim is .1. 'En a mechanical stoker, the' combination of a retort, movable grate-bars extending from both sides thereof, rocking-bars for moving said grate-bars, a piston and piston'iod located in a plane below the plane ot said rocking-bars, counter-shafts in the horizontal plane of said piston and on opposite sidesthereof, means carried by said piston rod for oscillating said counterarmslocated on the saine 'side of said piston shaft as said piston rod reciprocates, crankaims upon said counter-shafts and rockingbars, 'and means for connecting those crankrod. i,

2. in a mechanical stoker, the combination of a retort, movable grate-bars extending from both sides thereof, rocking-bars for moving said grate-bars, a piston and piston rod located in a plane below the plane of said rocking-bars, counter-shafts in a eeaeea 3. En a mechanical stok-er, the combination of a retort, Imovable grate-bars extending from both sides thereof, rocking-bars or moving said grate-bars, a piston and piston rod llocated in a plane below the plane of said rocking-bars, counter-shafts in the horizontal plane of s aid'piston and on opposite sides thereof, means carried by` said piston rod for oscillatingsaid countershaft as said piston rod reciprocates, crankarms upon said countershafts and rockingbars, and means for connecting those crankarms l'ocated'on the same side of said piston rod, said connecting means being adjustable laterally relatively to said crank-arms.

4i; in a mechanical Stoker, the combination orp a retort, movable grate-bars extend'- 4ing from both sides thereof, rocking-bars for moving said grate-bars, a piston and a pistn rod located in a plane below the plane of said rocking-bars, counter-shafts in the horizontal plane of said piston and on opposite sides thereof, a screw carried by said counter-shafts and screw bearings carried by the end of said piston and engaging with( of said piston rod.
