GATE FOR MECHANICAL STOKERS.

To 'all who/m it 'may concern: 1

Be 1t known that l, lVlLLIAM M. DUNCAN, a citizen of the United States of America,

residing in Alton, in the county of Madison i lated according to different grades andsizes of fuel.

The invention has for its objectthe proy duction of a gate ofthe kind named in which there are ay plurality of `fireproof members detachably connected to a carrier and which may be readily separated, when impaired,"

from the carrier to be replaced by new see tions. n

Figure ll is a view partly in. vertical section and-partly in elevation of portions of a furnace and mechanical stolrerzand my gate incorporated in the Stoker. Figli is a rear elevation of my gate, the Vcentral portion of the gate being broken out. Fig. 1H is a front elevation of the gate, the central portion of the gate being broken out. Fig. lV isA a vertical cross section of my gate taken on line IV-IV, Fig. III.

In the accompanying drawings A designates the side frames of a mechanical stolzer, between which at their forward ends and formingI the upper part of said side frames is a hopper B, (see Fig. I.) The sidefranies serve as supports for a traveling1 grate C thatis operable in part atlthe bottom of the hopper B, and said side frames are pref erably incorporated into a track thatpermits, of the Stoker elements being moved outwardly, although such construction is not essential in so far as my improvement is concerned.

D is an ignition arch supported above the traveling grate C in a furnace in which the Stoker is used, and adjacent to which my gate is locatedto serve as a means for regulating the movement of fuel upon the travcling grate from the hopper B to the ire chamber of the furnace.

No invention per se is herein claimed for the parts shown in Fig. I otherthan the gate, these parts having 'beenV described Specification of Letters Patent.

merely for the purpose of explaining thelocation and utility of my t ,ate.

sinks l? and'socket luggslJ (see Figs. H to Patented litar. n, totti.,

Application filed May 6,1969. Serial No. 494,343.

IV, inclusive,) which constitutes the upper 4 portion of my gate and is adjnstably supported by suitablev means such as vertical screw threaded. hanger rods' EZ fitted tothe socket-lugs Al" of thecarrier bar at, their loaver ends. These hanger rods have preferably secured thereon and have fitted thereto Worin Wheels 3 that are engaged by Worms as indicated at d, (Fig. lig-and through the medium. of which said Worm 'Wheels may ,be rotated. upon the hanger rods for the purpose of raising and lowering the carrier bar l with the parts detachably connected there'- to and which enter into the construction. of my gate as will hereinafter appear.`

5 designates a hanger rail suitably secured by screws to the carrier bar l at its front side, this hanger rail being of vright angle shape in cross section, (as 'seen in Figs. I and IV) and having one (6)' of its Wii'igs extending,- horizontally and forwardly from the carrier bar. Thecarrier bar l is provided With holt holes 7 that receive bolts 8 which extend through Athe carrier bar and also preferably through the vertical Wing of the hanger rail These b'olts preferably have their heads located at the rear sides of the carrier bar and seated in the countersinlrs la in ,the carrier bar so that their ends are iiush'with the rear face of the carrier ban-(as seen most clearly in Fig. im)V -Y t) designates detachable hanger plates having horizontal portions 10 at their upper ends that rest uponA the horizontal Wing of the hanger rail 5, and vertical portions bolt holes in the vertical portions 1l of the hanger plates, there being preferably tvvo of'therbolts 8 foreach hanger plate, as illustrated in the drawings.

l2 indicates sections of reproof material, preferably tireclay, that are attached inde -pendently of each other to the hanger plates 9 and which are, therefore?,susceptible to bein@F removed frornthe carrier bar l When the anger platesare detached therefrom.

The horizontal Wing of the Q eeh/iso Each` section l2 is provided with a bolt l Agate oi the character described coinholethat receives a boit lef; centrally positioned in the section and extending through the corresponding hanger plate vwhereby the section cletaehably connected to the hanger plate in order that it may be separated therefrom in the event of its becoming impaired in service. The head of each bolty lis preferably countersunlr into the section l2 in which. it is located, and the cavit7 between the heacl of the bolt and the inner tace o t'the section. is closed by aiiller 'l5 of lireclav. Eachnsection 12 has a recess 12 glitch receives the lower edge oi the carrier bar.

It. Will be seen thatin the event of either of the ireprooif sections l@ of my gate becoming impaired in service, said sections may be readily replacefi by ncrv sections Without, disturbance of the vother sections. the only acts necessaif,T for thelreplacing ol'l the previously need section by a neit7 one l 'being the disconnection of the hanger plate l) supporting section by the removal ot the nnts from the bolts 8 that connect said plate tothe carrier-bar andthe removal ofthe enel bolt 1.4 that connects the tireproo section to the hanger plate, the attachment ot a new reproof section, and the attachment, of the hang-er plate to the carrier bar. it isobvious that to eect saving of time in the attaching of a new iireproof' sectionv in place oi' one that has become impaired, the i'ireproof sections to be subsequently used may be kept on hand attached to carrier plates, in order that they may be immediately attached to the carrier bar l upon the removal of the previously used ireproo'f section and its hanger plate.

I claim:

l. A gate of the character described coniprising a carrier barhaving bolt holes, a hanger rail having a horizontal Wing, and a vertlcal Wing formed with -bolt holes registering with the bolt holes of fthe carrier bar, means for scouring the hanger rail by its vertical Wing to the carrier bar, a detachable hanger plate formed with a bolt hole, a horizontal portion seating on the horizontal iiange and a vertical portion formed with bolt holes registering with the bolt holes of the hanger rail and the carrierbar, a section formed With a bolt hole, and bolts detachably securing the vertical portion and the carrier bar together, and the section, fletachably, to the hanger plate.

prising' a. carrier bar having bolt holes formed with conntersinls, a hanger rail haring a horizontal. Wing, and a vvertical wing 'formed with bolt holes registering with the bolt holes of the carrier bar, means for curing the hanger rail by its vertical wing to the carrierbar, a'tlctachable hanger plate formed with a bolt hole, a. horizontal. portion seating on the horizontal i'lange and :i vertical portion formed with bolt. holes registering with the' bolt. holes of the hanger rail and the carrier bar, :i section. 4formed with a bolt hole and bolts having their heads located in the counter-sinks annldetachably securing the vertical portion and. the carrier bar together, and means secnringvthe section cletachably to the hanger plate.

A. gate of the character described coinprising a. carrier bar having bolt. holes, a hanger rail havinga horizontal wing, and :i vertical Wing formed with bolt holes registering with the bolt holes of the carrier bar, means for securing the hanger rail by its vertical Wing to the carrier bar, a detachable hanger plateiornied with :i bolt hole, :i horizontal portion seating on the horizontal flange and a vertical portion formed with bolt holes registering with the bolt holes of the hangen rail. and the carrier bar, a section formed with a bolt` hole having a countersinlr and a filler, and bolts detachably securing the vertical portion and the carrier bar together, and the section dctachably to the hanger plate.

4. A gate of the character described comprising a carrier bar having bolt holes, a hanger rail having a horizontd wing and a vertical wing formed with bolt holes registering with the bolt holes of the carrier bar, means for securno' the hanger rail by its vertical Wing to t e carrier bar, a detachable hanger plate formed with a bolt hole, a horizontal portion` seating on the horizontal flange, and a vertical portion formeel with bolt holes registerin With the bolt holes of the hanger rail an the carrier bar, a section formed With a recess receivinff the carrier bar and with a bolt hole, and zliolts detachably securing the vertical portion and the carrier bar together, and the section detachably to the hanger plate.
