My invention relates broadly to automatic stokers and more particularly to an agitator for coal hoppers used in automatic stokers. I p
6" One of the ob'ects of my invention is to ,rovide-a simpli ed construction of agitator lbr. coal hop s in automatic stokers.
Another ject of my invention is to pro-.,
1 "Iv'i'de-a construction of agitator for coal hoppers wherein resilient means are provided for subjecting the agitator to an adjustable tension to insure the periodical movement of the agitator.
A further object of my invention is to provide a construction of agitator for the coal hopper of an automatic stoker in which a multiplicity of resilient devices are arranged for subjecting the agitator to dif ferent degrees of spring tension whilebalj 2 arming the agitator for movement withinthe hopper under control .of. thescrew conveyor therein.
A still further object of my invention is.
to provide a construction of frame pivotally mounted within a coal hop er and operating as a rockable agitator for t ecoal within the hopper, a multiplicity of variable tensioned devices being connected to op osite parts of the agitator for subjecting t e agitator to varyin degrees of tension against the action 0 the screw conveyor within the'coal ho per.
ther and further objects of my invention reside in the simplified consturction of agitator for coal hoppers as set forth-more fully in the specification hereinafter following by reference to the accompanying drawings, in which: V
Figure 1 isa cross-sectional view taken through the hopper, agitator and screw conveyor of an'automati'c stoker on line 1-1 of Fig. 2; Fig. 2 is a cross-sectional view through the hopper and conveyor therein on line 2 -2 of Fig. 1; and Fig. 3 1s a perspective view of the agitator which is employed in the coal hopper of my invention.
In agitators heretofore employed in coal hoppers difliculty has been experienced by the breaka e of the agitator arms in the course of their movementthrough the coal provide independent-spring ,devi' within the -"hopper. "I -have-devised a construction of agitator which-is injthe natureof a rigid frameshavin' arms thereon and which, breakage under conditions of ,movement against relatively great: pressure of the""co al 1 within the hopper. In order to insure the fre a multiplicity of I is not subject to turn of the ag tator to. its initiaL 'sition; I.
mg difl'erent parts of: the' agitator-frame by which an adjustable tensionisjappliedto the agitator frame. The agitator frame has opposite 'imns thereofeonn'ected at their extremities to adjustable spring members, the tension on which may be changed in accordance with the wear of the a 'tator and natural deterioration of the resi ient parts. Y
Referring to'the drawings in more detail, reference character 1 designates nieces! hopper which connects to the trough 2 having end flanges 3 and 4. The end flange 3 abuts a ainst the end plate 5 in which the shaft 7 0% the screw conveyor 8 is journaled. The end 4 of trough 2 connects with the conveyor housing 6. A rod member 9 extends laterally across the hopper 1 and is secured by nuts 10 and 11 at opposite ends thereof in the side walls of the hopper 1. There is provided on with the inner cross-section of the coal hop er. It will be observedthat the trough 2 as converging side walls leading down to the base thereof through which screw 8 operates. The frame mem ers 15 and 17 are each shaped to conform with the contour of the eoiinect-' side walls of the hopper and with the contour of the converging walls of the tion h 2. The frame member 15 is bent at an ang e as I represented at 15". Framemember 17 is bent.
at an opposite angle as represented at 17.
The frame members 15 and 17 are continuous and are bent around an apex portion 22 as shown, The agitator member 16 extends into, the apex portion 22 and is riveted therein as indicated at 22 forming 2. depending extremity which is engaged by the screw 8 of the endless conveyor for the angular movement thereof according to the pitch of the screw conveyor 8 as represented in dotted lines in Fig. 1. The angularly disposed portions of the agitator members 15 and 17 of frame members 15 and 17 each carry the depending members 20 and 21, respectively, these members being riveted thereon as indicated at 20 and 21". The frame members 15 and 17 are bent inwardlyat their upper extremities as represented at 15* and 17 and are each apertured to receive the ends of coil springs 23 and 24, respectively. The other ends of the coil springs 23 and 24 extend through eye bolts 25 and 28 secured through the rear wall 1 of the hopper 1. The eye bolts 25 and 28 have. screw threaded shanks 26 thereon with lock nuts 27 screwed upon the shank 26 for engaging opposite sides of the wall 1*. lVhen it is desired to change the tension under which the one of the convolutions of the feed screw conagitator frame operates, the position of the screw threaded shank 26 of the eye bolts 25 and .28 is varied with respect to lock nuts 27 in the wall .1". To increase the tension, the eye bolts are screwed to a position closely adjacent the wall 1, thereby placing the coil springs 23 and 24 under the desired tension when the end 22 of the agitator abuts against veyor 8 as illustrated in Fig. 1. If it is desired to decrease the tension. the eye bolts are screwed and locked in a position further away'from the end Wall 1. The arrangement of the agitator is such that the desired condition of balance may be obtained by the independent adjustment of eye bolts 25 or28.
The washer members 18.and 19 serve to space the frame members 15 and 17 from the interior walls of the hopper 1 so that these frame members are free to move to their limited paths of angular movement without frictional engagement with the interior walls of the hopper 1. The tubular spacers 12 and 14 maintain the frame members 15, 16 and 17 in predetermined spacial ,relation regardless of the obstruction offered by the deposit of coal in the hopper. The rocking movement which is imparted to the agitator frame structure is determined by the pitch of the convolutions of the screw conveyor 8. The lower extremity 22 of the frame structure is maintained in spring pressed engagement with the screw conveyor and is shifted longitudinally through a distance determined by the pitch of the screw 8 to the dotted line 7 position illustrated in Fig. 1, at which time the agitator frame is free of the screw conveyor and may be returned to the full line position preparatory to a repeat operation.
I have found the agitator of my invention to be highly practical in its construction and successful in operation, and while I have described my invention in a certain preferred embodiment, I desire that it be understood that modifications may be made and that no limitations upon my invention are intended other than are imposed by the scope of the appended claims.
