CONTINUOUS-BURNING- FURNACE 330R BURNTNG ENAMEL WA'RE.

To'aZ'Z whom it mayconcem:

Be it known that we, CHARLES- BIoKMEinn and DANIEL A. LISTON.,"Olt] ;ZeI1S of the United States, residing at Bellaire, in the county .of Belmont and State of Ohio, have invented certain new andusefullmprove ments in Continuous-Burning Furnaces for Burning Enamel Ware, of which the followm'g-is a speclfication. I

This invention relhtesto a new and useful improvement in the manufacture of enameled Ware and it more especially re-' lates to a continuous burning furnace of enamel Ware. I a

The object-of the invention is to produce a furnace, through which the articles are passed by a continuous movement and with larl'y compressed. Fig. 3 is a transverse section through part of the device. 4 is an enlarged side view of oneof the standards; Fig. 5" and Fig. 6. are detail views of'parts of the standards. Figs. 7 8, 9-and 1O are perspective views of the blocks used in formingthe top, sides and bottom of the firebox ofthe iiurnace.

In these drawings the numeral 1 designates thefine box or :furnace proper which is placed upon '-.any suitable foundation. This fire box has .a'sbase' 2, consisting of two sides .3 and 4 set apart, so that there 1s a space 5 between them the-entire length of the base and open at its ends 6 7. "This I W 2 is m of any-suitable material I '17, The widthpf these blocks 10 is in any suitable way so as to act as-.asupport tor the superstructure 'Onthe to s 8 and 9-01 the sides 3and def-the base 2 1s placed a rseries or line of blocks 10, such as-shown in Fig. 9. side by side, the entlre jength of the. bnse2 These blocks 10 haveilat flush bottoms 1 1, sides'12'and ends 13.

channels 16 of these blocks 10 are a'lined and form continuous channels the entire length of the furnace on ,eech side thereof.' The blocks 10 have their outer edges flush with the outer edges of the sides 3 and 4 and these blocks project inwardly beyond the inner faces of the vsides 3 and 4 and partially over the space 5.- The blocks 10 of one series on one side of the furnace are from theblocks 10 .of the other series on the other side of the furnace so that there.is a

space 18 between the blocks of the two series, the (space l8 being open at its ends and connecting with the space 5 between the sides 3' and 4;. On top of these blocks 10 at the inner ends of these tops is placed side by side the furnace-on eachside a series or spaced apart 'k bl k 19, hown/in Fig. 9. These I blocks '19 have in their bottoms 20, the ribs 21, adapted to fit into the inner channel of the blocks 10 and flat surfaces 22 to fit on, v

fiat ribs 15 of .the blocks 10. These'blocks 19 have at their inner edges top projections '23,. The tOPSQfl of these blocks 19 have the downward and backward curves 25. The

projections 23 may extend slightly beyond the inner edges 26 of the blocks 19. The blocks 19 extend beyond the inner edges of the blocks 10., so as to bepartiallyabove the space18. But the projections 23 are to be slightly spaced apart, there being a space 27 between-the opposite projections of the two series oi blocks 19.. This space 27 should be just ahout sufiicient to provide a clear passage f orkthe stems of the stand ands as will be explained. This space 27 opens downwardly into a space between the lower parts of the .endsof-the blocks 19 and into the space 18 and the space between the opposite ends of the blocks 19' of the twouse me is open at its ends. Back of-the .blocks. 19;, there is placed endwise npon the ptQPS 14 of the. blocks 10 a series .ofbl mks 28; shown in Fig- 8.. These ocks .28 have on their bottoms 29 ribs 30 fitting grooves 16 and flat surfaces 31 fit ing flatsurfaces 15 of the tops 14: of the blocks 10. These blocks 28 a so [ha e at their sides inter-fitting, ribs 32 and .groovesfiii, so that the series of blocks 28 on each side of the furnace will beginter: looking .and tight-fitting. These blocks 28 also haze passing through them the two pas- Sages Bland 35; the object of which will be explained. These blocks 28 have on their tops 36, at the inner ends 37, the upwardly 60 M 4 of the base.

verse tapering grooves with two outlets 57 and 58 leading to and passing partly through the passages 34' and fire box of the furnace.

tapering ribs 38, which form continuous tapering ribs, one on each side, at the tops of these blocks 28, the length of the fire box 1. On these ribs 38 rest the cover blocks 39, shown in Fig. 7 These cover blocks 39'have on their under side near their ends 40 trans- 41 adapted to the ribs 38 of the side blocks 28, the ribs fitting into said grooves. At their middles on the un derside these blocks 39 have depending transverse tongues 42. On each side of these tongues the bottom face of the blocks 39 has upward and outward curves 43. 0n top these cover blocks have on the ends the bevels 44. r

After the several sets of blocks 10, 19, 28 and 39 are put into place with their several ribs and grooves interlocked, as illustrated in Fig. 3, they are bound together as by end plates 45, with bolts 46 connecting these plates and passing along the bevels 44. At each corner of the furnace is placedaven tical angle plate 47 .through the topends 48 of which angle plates the bolts .46 also pass. Attheir lower-ends'49, these angle plates also secured 'to angle bars 51 embedded transversely in the base 2 of the fire box 1. These bars 51 extend out each side beyondthe base 2 of the fire bQX 1'. On these bars 51 on each side of the base 2 are placed the air-supply pipes 52 and gas-supplypipes 53.

The air-supply pipes 52 have the inducts 54 provided with valves 55 and adated for connection with any air supply underpressure. -The'se air-supply pipes 52 have rising from them a number of educts 56 provided 35 in blocks 28, there being one educt for each such block 28. "The gas-supply pipes 53 are to be connected with any gas supply, natural gas or other. These gas supply pipes 53 have educts 59, as many as there are educts 56, having outlet pipes 60 and 81 which pass through glands 62 and 63 into the outlets 57 and 58 and beyond the inner ends of the latter into the passages 34 and 35.

The construction described produces a furnace having a chamber above, a base below with spaces connected one with another ver-v tically and open at their ends, and pipes for supplying air and gas to the interior of the Into such a device the wareto be enameled is to be continuously passed by the construction now to be described. i

An endless track 64 is located in a horizontal plane and so as to pass lengthwise through the space 5 between the sides 3 and This track 64 is 'supiiiorted uponthe beams 51 at its straight portions and at its curved ends- 66 and 67 upon suitable pillars 68 and 69, which are firmly braced to support th track and resist strain.

47 are braced by rods 50, which are I ' llhese pillars 68 and 69 rise from suitable base plates 7.8 and 71, one at each end of the device. 1 The base plate 70 is made adjustable'by means of the screw 72 in any usual way for a belt tightener, so thatthe curved end of the track at this end may be adjusted to take up slack. Stepped into the base plate 71 and rising therefrom is avertical shaft 73 carrying a worm wheel 74 engaging a Worm gear "the engine 76; Above the worm wheel 74 thereis keyed tothe shaft 73 a sprocket wheel 77. Stepped into'the base plate 70 and rising therefrom is a vertical shaft 78 to which is keyed Engaging the teeth of these sprocket wheels 77 and 79 is the endless chain 80, clearly indicated in Fig. 2, as a chain and diagrammatically in Fig. 1. To this chain 80 are secured buggies 81 carrying the standards 82. .The buggies 81v consist of a frame 83 havingrjpurnal bearings 84 in pairsin which fit the journals 85 of rollers 86, and vertical arms 87 for attachment to the chain 80 and the standards 82. file one side of the arm 87 of thebuggy 81 isse ie ired a plate 88, having two ears 89 by which the buggy is fastened to the chain 80.- The vertical arm 87 of the buggy 81 is made-hollow or withthr'ee'sides and has at 'the top the threaded 31016.90. Into this hole is securedthe lower end 91 of the stem 92 of the standard 82. Toitl e top which rise fingers 95 having the finely pointed tips 96.

- Operation: The 'apticles to be enameled after preliminary preparation are placed, as I indicatedin Fig. 3, upon the finely pointed tips 96 of the'fingers 95. Theengine is put 1 into, operation and through the worm gear mechanism the sprocket wheel 77 moves the chain 80 and with it the buggies 81, standards 82 and the'supported articles upon the standards. As the track 64 with the chain 80 are located in a horizontal plane, the buggies with the standards are always in a vertical position. Gas and air are admitted "into the annealing chamber through the outlets 57 and 58 and the outlet pipes (i0 and 61, and ignition is made. As theogas and air combined are forced into the annealing chamber, the curved shape of the bottom and top of the annealing chamber causes the flames to take a course indicated by broken lines in Fig. 3. The curved shape to the bottom and top of the annealing chamber is given in the latter instance by the ole-- pending tongues 42, and in the former instance by the projections 23. Hence t flames are thrown both on the outside'ane. the inside of the articles to be burned.

Vfith such a device, the heat within the annealing chamber may be retained constant, and the amount and degree applied 7 5 whichreceives power from another sprocket wheel 79.

of this stem 92 is secured a three-armed frame 93 from the ends 94 of the arms of.
