IRON STRUCTURE FOR OVEN-BUILDINGS.

Specification of Letters Patent.

Patented Sept. 29, 1908.

Application filed March 20, 1907. Serial N 0. 363,336.

To all whom itmay concern:

Be it known that I, KARL BERNHARD, a v subject of the Em ero'r of Germany, and resident of Berlin, ermany, have invented certain new and useful Improvements in Iron Structures for Oven-Buildings, of which the following is a specification.

My invention relates to the iron structure of buildings or houses containing ovens, or retorts which structure serves to support the roof as well as the bunkers and charging devices. Iron structures of this character have frequently been carried entirely, or in part, upon the ovens or their anchoring framework connected with such ovens or framework. Such rigid connection has in practice proved objectionable, on account of the motion of the oven or furnace, due to expansion and contraction, this motion being transmitted to the iron structure and creating therein injurious strains, which cannot be figured accurately, and in view of which the parts have to be made much heavier than would be required otherwise, so that the advantage of using the oven or furnace as a partial support is at least a very doubtful one. To avoid these injurious additional strains, which in some cases may be much greater than the main strains due to weight, I have devised my present invention, according to which the iron structure is connected with the oven, or its anchoring framework, not rigidly, but loosely, or movably, so that the brickwork of the oven or furnace may move independently of the supporting framework of the building. The'vertically acting Weight of the roof and of the charging work of the roof, is borne directly by the oven structure. The side walls of the building can be simply sus ended from the roof and thus a considerable economy can be effected, as compared with the usual construction of such buildings.

In the accom anyin drawings I have illustrated severa embo iments of my inven- Figures 1 and 2 are a side view and end view respectively of an oven, which serves as the only support for the framework carrying the bunkers and the charging devices. Fi 3 illustrates a form of my invention in whic the framework is connected with the roof structure. Figs. 4, 6 and 8' are side views of the joints employed by me between the framework and the oven, and Figs. 5, 7 and 9 are correspondin end views.

In Figs. 1 an 2 the oven or furnace a, which may be of any suitable construction, and consists of masonry or brickwork, carries on its u per surface a supporting framework 6 for tl fe bunkers and charging devices. This framework consists of several sections, linked together by pivotal connections, as indicated in Fig. 1, so that each will to a certain extent move independently of the others. This framework b rests on rolling members, suchas balls, rolls, or roll segments 0, which may be journaled or seated on the u per surface of the oven, or on the framework 1) itself.

Figs. 4-and 5 show u on an enlarged scale a construction in whic ball segments 0 are loosely supportedon the upper surface of the oven a. On these ball segments the osts d of theframework I) rest by means of p ates e, located at the lower ends of said rovided, if desired, with lateral flanges f. imilar lates are located on the upper surface oft e oven.

In Figs. 6 and 7 I have shown another construction in which the roll segments 0 are pivotally supported on the oven and carry the posts din the same manner as previously described. In Figs. 8 and 9 the posts d are ivotally connected with roll segments 0 w ich are loosely supported on plates e, resting on the upper surface of the oven in the same manner as in Figs. 4 and 5.

It will be seen that in each of these constructions the oven receives the vertical downward strain from the supporting posts d, but these posts are capable of moving relatively to the oven, in case the latter should ex and or contract in heating or cooling.

n Fig. 3 the supporting framework 6 is carried by the oven a in the same manner as hereinbefore described, and has in addition a peculiar connection with the roof structure 9 ,of the building h, allowing the framework 6 to move vertically, yet preventing its horizontal movement. For this purpose the framework 9 of the roof is provided at the inner ends with rolls "5, engaging either the supporting posts d, or special guide posts. Lateral stralns are thus transferred to the building it, while at the same time a sagging of the oven will have no influence on the building it.

The supporting posts d, resting on the oven or on its anchoring framework loosely, as by means of balls, rolls, or segments of such elements, will not follow the oven in any of its lateral movements, and thus detrimental stresses in the framework will be avoided.

I claim as my invention:

1, The combination with an oven, of a framework located above the oven, and roll ing connections interposed between the oven and the framework.-

2. The co1nbination,with an oven and the building wherein such oven is contained, said building including a roof projecting above the oven, of a supporting framework having a loose connection with the top of the oven l and arranged in guiding en agement with and between parts of the roo 3. The combination, with the oven, of a supporting framework resting on the oven and having a loose connection therewith, and

the building containing said oven and provided with a roof having members projecting towards each other and in sliding engagement with the said framework to guide the same vertically.

4. The combination, with the oven, of a supporting framework resting thereon loosely and comprising sections connected with each other loosely, so as to be capable of movement relatively to one another. In testimony whereof l have signed my name to this specification in the presence of two subscribing witnesses.
