Specification of Letters Patent.

ippiication filed November 18, 1912. Serial No. 731,976.

' ces its hott I mudrmgdnbecomes in. time issed. no consists i a G; no r wheleoy the i cles tne inner iorrning' the cons frame or mud-ring tom of the space around a 1 between the weds c and b and forms therewith the Water jacket.

This frame, in accordance with the present invention, is preferably constructed thus: It is preferably a solid endless casting bored for the reception of the rivets 6 whereby the I outer and inner walls of the boiler are secured thereto. Integral with this casting and depending downwardly therefrom zit suitable intervals are the upper sections f the sediment receptacles or mud pots each or which sections is open downwardly and has an exterior flange g and a reduced neck or neck portion. h forming a continuaticn of a passage 6 which extends vertically through the mud-ring. In the preferred construction the neck portion h for each section is at the outer side thereof, so that section is substantially wholly under the boiler. Where the securing points for the walls a e coincide with the passsges,instead of using rivets which would obstructthe passages, I use patch-bolts k as shown in Fig, 2 and on a larger scale in Figs. 3 and 4:.

Each mud-pot or sediment receptacle inchides aiower section or cap Z,'preferably hollow and open at the top. It has an exterior flange mouth,

whereby, by the use of bolts n or the e, it may be secured to the upper section f form the mud-pots, suitable packing 0 beng interposed between the sections, Each LOWGI' section 3 has in the bottom thereof it discharge opening 39 which is internally threaded to receive a removable plug g.

It will he understood that the tops of he grate bars (not shown) are about coinident with the top oi? the mud-ring, as in e usual construction. Any accumulation or sediment tslres place in the improved boiler not upon the mud-ring where it will give rise to the burning out of the mud pct-including portion of the boiler, but in the, mud-pots where it is .well below the level where the heat of the fire is effective to accomplish the burning out. The sediment collecting in the mud-pots may be withdrawn from time to time by removing the plugs Q.

I prefer to provide the boiler also with Patented Apr. 1,1913.

m around its upper edge or means for retarding, if not preventing, the.

L ecciirnnlction of sediment thus: The top of the section f of each mud-pot is provided with a. circuleropeningr and a correspond ing opening 8 is formed in the arch b'of the wall 6, and into these openings are fitted the ends of s pipe t, there being as many of such pipes as there are mud-pots. The ends of these pipes are expanded so as to make a tight joint at the openings 1' and s by suit able tools entered at the bottom of each section f (the complementary section Z being removed) and through openings u in the arch of the wall a, said openings u having the removable plugs '21. The pipes 25 are preferably bent so as, to allow them to em and and contract to avoid starting the oints at r and 8. This construction permits a circulation of the water in the boiler to take place substantiall as indicated by the arrows in Fig. 1, so t at the tendency for sediment to collect is reduced.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is 1. Incombination, with a boiler having a fire-box space, a water-jacket flanking said space anda mud-ring forming the bottom of the water-jacket and arranged substantially coincident with the fire-level in said space, a sediment receptacle arranged below the mud-ring and having its interior communicating upwardl through the mud-ring with the interior 0' the water-jacket, said receptacle having means to withdraw therefrom the sediment collecting therein.

2. In combination, with a boiler having a firebox space, a water-jacket flanking said space and a mud-ring forming the bottom of the water-jacket and arranged substantially coincident with the firelevel in said space, water-conducting means connecting the memes water-jacket with a relatively higher part of the boiler and including a sediment reccpt-acle disposed below the mud-ring and communicating upwardly through the mudring with the interior of the water-jacket.

3. In combination, with a boiler having a fire-box space, a water-picket flanking said space and a mud-ring orming the bottom of the water-jacket and arr-an ed substantially coincident with the-fireevel in said space, water-conducting. means connecting the water-jacket with a relatively higher part of the boiler, extending through the fire-box space and communicating with the interior of the water-jacket upwardly through the mud-ring.

4:. In combination, with a boiler, having a fire-box space, a water-jacket flanking said space and a mud-ring forming the bottom of the water-jacket and arranged substantially coincident with the fire-level in said space, said mud-ring havin a downward and downwardly 0 en hot ow projection, and a cap removab y secured on the open side of said projection and forming therewith a sediment receptacle and said receptacle communicating upwardly through the mud-ring with the interior of the waterjacket.

In testimony whereof I afiix my signature in presence of two witnesses.
