.application filed March 13 To f/.ZZ whom t may camera:
Be it known that l, liv/WILLIAM S. Srnnn, citizen of the United States, residing at Louisville, in the county of Jefferson and State of Kentucky, have invented certain new and useful improvements in Drawing Apparatus for lilns, of which the followingA is a specication, reference being had therein to the accompanying drawing.
This invention relates to a drawing* apparatus for kilns, and is more especially useful in connection with vertical lime and cement kilns.
ln a prior patent issued to myself under date of Oct. ll, 1904, No. 772184:, there is disclosed a drawing device or apparatus, which has been extensively used with some considerable success, but there are certain ,Y
a view to better eiliciency and larger economy in the operation of the kilns.y
More particularly, the invention includes a. drawing device adapted to have a reciprocating or to-and-fro movement beneath the outlet opening of the kiln chamber, and novel and improved operating means for imparting the necessary reciprocating movement, said operating means being adapted to be quickly adjusted whereby to vary the throw of the drawing device, and without the necessity of removing parts or interrupting the 'operation of thekiln.
It is further contemplated by the invention to provide in operative association with the discharge opening of. the kiln, a drawing or discharging device, novel supporting means for the discharging device, pivotally mounted actuating` rods or links for the drawing device, and means for ad justing the fulcrum for said rods.
Again, an important feature of the in- 1519. Serial No. 282,502.
vention resides in the provision of a plument it will simultaneously adjust the movei the description to follow, which, for a clear understanding of the invention is to be considered in connection with the accompanying drawings, forming a part hereof, and wherein is disclosed for the purpose of illustration, -a convenient and satisfactory embodiment o-f the invention, though in this connection, it is to be understood that minor changes may be resorted to without.
departing from the spirit or contemplation of the invention.
ln the drawings,
'Figure l is an elevation of a preferred embodiment of the invention illustrating a plurality of operatively associated drawing devices with operating mechanism therefor appliedto adjacent kilns, the latter being shown in section, away.
1 Figure 2 is a top plan of the drawing devices, separated from the kilns proper, and one of the dra-wing `devices being broken away. s
lilith more drawings, like reference numeralsrefer to correspondingdrawings throughout the several views, in which, l represents generally the frame-work'of the apparatus, the side walls of a kiln, and 3 the bottom wall thereof. These kilns are preferably arranged in duplicate, as illustrated, with an in erif'eninp; space e of operating means to kbe presently departicular reference to thek and parts being broken .A
for the reception scribed. rl`he kilns are adapted to receive the rock la to be calcinated, and each kiln is provided with an opening in the bottoni wall thereoficoininunicatingwith a suitable discharge chute Positioned below the discharge chutes is the continuous draw, preferably constructed'substantially as follows: 6 is a horizontally disposed platform or table arranged in the path of the discharging material, the platform having at a point substantially midway of the ends thereof an opening` 7 cornnninicatingY with a discharge chute 8, conveniently project- .ing` laterally and adapted to deliver the material onto `longitudinally extending endless conveyor D of any appropriate type projectinzgat a slight inclination towards the outer end there-ot, and disposed at its upper end above a transversely movable conveyor l any suitable type to bo dis charged therefrom onto cars or the like by means oit a suitable chute or chiites not necessary to illustrate or describe herein. The drawing` tables are conveniently supported by links ll, conveniently iour at opposite sides of the table arranlred in pairs,
i with two pairs at each side ot the discharge chute 8. The links are pivotally connected at the top to the table platform 6 and at the bottoni to the traine-work lin any suitable manner tor'tree oscillating ino rement. As the table is moved back and forth the link supports have a tendency to cause .tl material to leed to and gradually discharbe through the chute 8. Actuating means for the tables conveniently takes the forni ol an elongated bar or bars l2 pivoted at the outer end at 13 to one end of the table and pivotally:supported,as at le to a vertically disposed link le?, which latter connected tor vertical adjustment at will, preferably throuuehthe medium of an adjustin@v rod extension l pivotally connected to the link at i6, and having a threaded terminal i7. The adjusting rods tor the respective linliis ll proyect through suitable apertures in the traine-work l" and a; hand operated nit ith interior threads corresponding to the threads of the adjustH ing rods l5 is positioned on each of said rods and adapted to rest upon a bearingnleinber or washer 18 loosely sleeved on the adjusting,` rods and adapted to contact with the upper surface oi' the 'framework la. An elongated ldrive shaft 19 is provided, the saine adapted to receive rotatable motion through the medium of a inotor or the like, and having at its inner end a drive pinion 2O adapted to engage a gear wheel 2l mounted on a suitable shaft 22 and cai rying a pinion 23 adapted to niesh with the gear wheel 24. The gear wheel 24 has pivotally connected thereto asuitable pitrnan rod 25E pirotally connected at 2G to the upper endV or an actuating` member 2i' which latter is'pivotally connected at 28 upon a suitable support for swinging movement and has at opposite sides elongated vertically disposed slots 29 tor the reception of pintlcs conveniently torined by extensions ot the pivotal connection le between the adjustable links lila and actua-tingv rods or bars 12.
Projecting); below the kiln at opposite sides ol the discharge chutes 5 are vertically disposed plates 30 extending tol a point acljacent the table 6 whereby to constitute contacting parts for the discharged material on the tables and to vent the same from falling;` oil the outer ends et the tables 1n the movement ot the latter, and whereby to assist in the gradual inoveinent opt the inat lal to the disci e openings 7.
rllhe operatioi'i in L be brieily reviewed as follows:
The, linie or other material from the kiln gradually [lows by gravity through the dscharge chutes onto the oscillsfrtine; t; n'es or platforms (l supported by the pivoteo or links ll, the tables receiving.' their motion by the actua-ting' rods through the inedii ot the swinging actuating,V nieinbelr 27 driren in the inanner iull'v `Idesciibed by -.eans of the gear operated pitnian 25. rlhe pin and slot connection let-E29 between actust-in,g` rods l2 and the swinging act-i ing inornber 2'? provides a shilftable connection, whereby the lengtl ot oscillation or" the tables or plat'forlns may be accurately controlled by raising or lowering the instable linlis lfl by ,inetfy f "i the adjusu extension rods l5. the material is .drawn onto the oscillating tables it is gradually fed through the chute 8 between the sections ol the tables onto the,
lt has been ascertained that by the usey ot the present apparatus, the rate at which the Iiln may be drawn, may be accurately ad justed to ineet the requirements of' 1aroper calcination of the rock, and a more eliicie'nt operation results.
