6 Claims. (Cl. 214-55) This invention relates to incinerators and more particularly to improved means for charging an incinerator and at the same time eliminating the danger of smoke and/ or flames blowing out through the charging hole or door of When the incinerator cover or door is opened and such' material swept or dumped into the charging hole, it may burst or flash into flame and burn at such a rate that the draft through the stack is insufficient to avoid the temporary buildup of pressure in the incinerator. Under such conditions flame and smoke may blow up through the charging hole into the charging room, possibly igniting other combustible material with resultant fires and/ or burning or otherwise injuring the operating personnel.

The chief object of the present invention is to provide improved incinerator charging means which eliminate the possibility of accidents such as described above.

It "has been proposed heretofore to provide a charging container into which the refuse is loaded while the charging hole of the incinerator is closed by a suitable closure member, and to connect the container and closure member so that the charging hole is opened as the container is moved to incinerator charging position and is closed again as the container is moved backto loading position. The present invention provides such container and closure means of simplified and improved construction, and in addition a cover or door for the charging opening of the container together with locking means such that the cover can be opened only when the container is in its loading position and such that'the container cannot be moved to incinerator-charging position when the cover is opened. Thus flareback through the charging container is prevented.

One embodiment of the invention has been illustrated in the accompanying drawings, but it is to be expressly understood that this embodiment is for purposes of illustration only and that said drawings are not to be construed as a definition of the limits of the invention, reference being had to the appended claims for this purpose.

In the drawings,

Fig. 1 is a side view of apparatus embodying the invention;

Fig. 2 is a plan view of Fig. 1; and

Fig. 3 is a view taken from the right-hand side of Fig. 1.

It will be understood that the invention can be used in conjunction with any desired type of incinerator, the

, details of which form no part of the present invention.

2,840,249 Patented June 24, 1958 By way of example, the drawings show part of the floor 1 of a charging room, and part of an incinerator 2 located below the floor and having a charging hole in the floor 1 as indicated by the dotted lines 3.

Preferably and in the form shown, the charging container is pivotally mounted on the floor 1 above the charging hole 3 so as to be swingable between a charging position in which its discharge opening registers with the charging hole and a loading position in which it may be loaded with material to be burned. Preferably also the closure member for the charging hole forms part of the pivoted structure so that the hole is automatically closed whenever the charging container is swung away from its charging position.

In the form shown, the pivoted structure is mounted on a suitable foundation 4secured to the floor 1 in any suitable manner as by means of bolts 5. Suitable standards 6 are mounted on the foundation 4, preferably by means of the bolts 5, to provide bearings for the trunnions 7 of thecharging container 8' which may suitably comprise a substantially cylindrical drum;

The foundation 4 is provided with a pair of arcuate guide tracks 9, the free ends of which maybe connected by an angle 10 for strengthening purposes, and ,the lower end of the drum 8 is correspondingly arcuate, and preferably provided with arcuate runners 11 which slide in and are guided by the tracks 9. It will be understood that the lower end of the drum is open' and that in the position shown in full lines in the drawing, this open, lower end is in registry with the charging hole 3 which is continued upwardly through the. foundation 4 as shown in dotted lines in Figs. 1 and 2. y g

If desired, the guide tracks 9 may be provided as flanges on the edges of an arcuate plate 12 which is provided with an opening over the charging hole 3. Similarly the runners 11 may comprise flanges on the edges of a' similarly arcuate plate 13 secured to the lower periphery of the drum 8 and havingan openingconforming to the open end of the drum and the charging hole.

At one side of the drum, the runners 11 and plate 13 V opening 14, 15 in theplate 13, the side flanges 11 being widened if desired to cover the sides of the refractory The drum 8 is also provided with a suitable cover plate or lid and locking means which, as stated above, permit opening the cover only when the drum is in its loading position and also prevent movement of the drum to charging position when the cover is open. The cover itself may take any suitable form, preferably being pivoted on the container or drum 8. As shown, a pair of brackets 20 are secured to the upper end of the drum on one side, and a hinge pin or shaft 21 passes through these brackets. A lid or cover 22 fits on the top of the drum and is provided with a pair of laterally extending arms 23 having openings through which the pin 21 passes to mount the lid pivotally on the drum. The arms 23 may be extended beyond the hinge pin 21 to carry a suitable counterweight 24. A suitable handle 25 may be provided on the cover if desired.

The locking means described generally above pref- 3 erably take the form of a rod or link 26"pivoted on a pin 27 which projects from one of the arms 23. The lower end of the link passes freely through a guide bracket 28 secured to the drum 8 and its end engages the surface of an arcuate cam member 29 suitably.

mounted on the brackets 6. It willbe seen that'the cover 22 cannotbe opened as long as the end of-the link 26 engages the cam, although the assemblycomprising thedrum 8,. cover 22, and link 26 can swing freely about the axis of the trunnions 7 to and from the charging position shown in full lines inthe drawings. When the. drum reaches its loading position shown in dotted lines in Fig. 1, however, the end of the: link reaches a hole 30 in the cam surface and the cover 22 can be raised inasmuch as the link 26 can move longitudinally through the hole 30. At the same time, however, the pivoted drum is locked in its: loading position and cannot be moved therefrom until the cover is closed to withdraw the link from the hole in the cam surface.

If desired, suitable stop; means can be provided to limit the swinging movement of the drum 8 at either or both ends of its travel. ,As shown, a stop 31 is secured to. a flange 17 in position to engage a bracket 6 when the drum. reaches itsgcharging position, and a similar stop 32 engages another standard 6 to limit movement of the drum to its loading position. 7

The use and. operation of the apparatus will be clear from the foregoing description. Briefly summarized, the contents of the drum fall. by gravity through the charging hole of the incinerator whenever the drum is swung to its charging position shown in full lines. At all such times,.however, the cover 22 is held in closed position on the drum,rpreventing flarebacks. As soon as the drum has been dumped, it is swung back to its loading position shown in dotted lines where the cover 22 can be opened for loading. The charging hole 3 is now covered by the refractory body ;16, and. thisposition of the parts cannot be'changed. without first closing the cover 22 to withdraw the link 26. frorn the hole 30.

It 'willbe understood that the embodiment of themvention described'above is'by way of example only and that the invention is not restricted thereto. Reference should be had to the appended claims for adefinition of the limits of the invention,
