UNITED STATES PATENT OFFICE.
'HENRY e. WATSON, or DETROIT. MICHIGAN, .essIeNon f DETROIT, MICHIGAN, A conromTIoN o MICHIGAN.
cLINxEn-BAE.
To all 'whom 'it may concern.'
B e it 'known that I, HENRY G. WA'rsoN,
a citizen of the United States of America, I'eslfsiding'l at Detroit, in the-county of Wayne and State ofMichigan, have invented ce1'- tair. new and useful' Improvements in Clicker-Bars, of` which the following is a specification, reference being-had thereinto t ie accompanying drawing.
In autcpnatlcl stokers and other furnaces of theftypcinwhich inclined, movable 'grate bars are employed, a rotatable clinker bar isusuallymounted at -thelowerendsmofl-said bars to rind or crush the clinkers and gradually feed out thc ash. It was foundI that the 'extreme heat to which these clinker bars were subjected caused them to warp, crack andl become partially disintegrated in ya shortltime, and 4to -obvate these diliculties clinker bars have been made up of a plurality of sections strung upon and secured to suitable shafts. In practice, it is however, nece ssary to make the shaft .very large j and heavy so that it will not be twisted and `broken under 4the heavy strain of rotating the clinker bar to crush clinkers, and further,
`it is also necessary to form the shaft and sections or otherwise connect them so that thesections can `not turn on the shaft.. The construction 4is therefore necessarily cumbersome and expensive ,t'o manufacture, and diilculty vis experienced in assembling y .The object of this inventionis to provide a sectional 4clinker bar construction which embodies' comparative lightness. and cheapl nessof manufacture with reat strength and i '.rigiditynbviatin .alllia, ility lof breakage' of theshaft an `.giving a. ,construction `in which the 'sections may be quickly andeasily `removed for replacement or 1 repair; Wit titese and other ends 1n view, the invention y consists in the matters hereinafter set forth and more particularly pointedoutinthe appended claims, reference being had to the accompanying drawing in .whichs- Figure 1 'is a longitudinal section through afpolftion of a furnace illustrating a clinkerbar embody'in X. the invention in operative l The grate bearer 5 s Vries of transverse bearln members 9 form- 70 l 'tion to show the construc-y Specicationof Letters latent. Patented Sept. 10, 1918. i apnpmon mea January 1e, 1914. serial No. :$12,492.
Fig,4 2 is a transverse verticalsection ithrough the same; and
supported at their lower ends upon the uptab e notches 8 in said bars 3 and raise `andlower y66 the bars as the slitifts are turned` all bein constructed and aranged in anoldand 'we l' known manner.
i-s provided with a ing bearingsV for a rotata le clinker bar10- comprising-a tubular shaft 11 upon which are sleeved a number of sections 12 provided with'a plurality of teeth or studs '13. These sections are of such a 'length that they ex- 76. l'
tend' from near one bearing to a point adjacent to the next bearing and sleeved upon the shaft between the' toothed sections are short plain ybearing sections ltudaptedto turn in thebearings `9. At each end, each 80 of the sections 12;.and 14.` are formed with f notches 15 in opposite sides,y said notches 'forming between them longitudinally extending lugs 16 to enga-gethe notches In the e outer `end of theislee've is substantially 90.-? rectangularV in crosssectional outline. but 1t lmay be formed inan suitablemannerto b e ""engaed-by means" notshown) for turning-t e clinker bar and itsinnerend is vided with lugs and notches correspon terlock with the"adjacent section.` extending through opcningsin the shaftlt ing section l-l,l hold theshaft against lungi-..-

MURPHY InoN woexs, or

tion' prevents longitudinal movement of the clln'ker bar in ite bearings. m't'he grate bearer;
'As the povver is applied to the sleeve 17 which is interlockcd with the adjacent end of the firstv ofthe in'terlocked sectiona'the twisting strain of turning the clinker'bar is taken by the sections-direct and the shaft shaft, -a` Series-of sectione formed :with elilso 11 simpl forms a support furthe sections'. The sha t may' therefore be made comparative1y l ight and tul'Jularv (as shown) if desired, so that airor steam may be circulated therethrough to' assist in keeping the'bar cool and prevent the same from being hurried or 'warped by the excessive heat. The ar rangement of interlocking sectionsv also per-v mits ofthe use 'of a length of stock tubing or shafting anld-it is unnecessary toform or machine the shaft, thus greatly 4leseening the cost'of manufacture as "the sections' may be readily cast with their interlocking lugs and simply strung upon the shaft..
' Obviously, changes may, loe-made in the construction and arrangement of narts Without departing from the spirit of my invention and I do vnot therefore limit .myself to the formv ort-arrangement shown.
Having thus fully described my invention whatl claimis'cw- 1.` A 'rotatable linker-bar comprising a s`e ries'fof tubular Sections having formed ends adapted to interlock, a shaft extending throughv and iittingfwithin'said sections to aline the same and 'turn therewith and to form a strengthen-ing and supporting member therefor., `and means for applying'povve-r to vone of said sections to vturn the'bar.
