UNITED STATES PATENT OFFICE.
LORENZO C. IBUGKLEY, OF LISBON, OHIO, ASSIGNOR TO THE It. THOMAS & SONS COM- PANY, OF EAST LIVERPOOL, OHIO, A CORPORATION OF OHIO.
SAGGER.
Application filed March 27, 1925.
To all whom it may concern:
Be it known that I, LORENZO C. Buckner, a citizen of the United States of America, residing at Lisbon, in the county of Colunr biana and State of Ohio, have invented certain new and useful Improvements in Saggers, of which the following is specification.
My invention relates to saggers, and the object of my invention is to provide a sagger having circumferentially spaced lateral bosses which insure proper spacing between adjacent bungs in the kiln, so that thorough circulation and uniform distribution of the kiln gases around all of the saggers is obtained.
In the accompanying drawings-- Fig. 1 is a plan view of a sagger in which my invention is embodied in one form;
Fig. 2 is a broken side elevation thereof,
Fig. 3 is a side elevation of juxtaposed bungs having saggers of the present type; and
Fig. 4 is a plan view thereof.
Inasmuch as the bungs are commonly arranged as closely as possible within the kiln, andthis operation is performed by hand, it happens not infrequently that they are placed so close together, or that the saggers are so inaccurately superposed that adjacent bungs come into contact. The same result may occur during firing through failure of a sagger with resulting inclination of the bung into engagement with its neighbor. Under such conditions the circulation of the kiln gases between the bungs is interrupted and uneven, or deficient heating of the saggers occurs. As a result the firing operation is non-uniform and is incomplete in certain bungs, and complete in the balance. Defective products result whenever this happens.
The present invention provides a sagger so constructed that too little spacing between the bungs is impossible under any conditions. Consequenly an even and uniform firing of the entire kiln charge is assured.
Referring to the drawings, I have shown a substantially square sagger, the four sides 5, 6, 7 and 8 of which are integral with the bottom 9, upon which the article, or articles,
Serial No. 18,891.
to be baked is placed. Projecting from the outer face of each side wall of the sagger is a circumferential arcuate boss 10 integral therewith. Preferably each boss is of materially less vertical extent than the side wall of the sagger, and its lower portion 11 slopes inward toward and merges at its lower margin into the wall. As the kiln is filled by the building of the bungs 12, the bosses 10 of the several saggers insure initial spacing between the bungs and maintain that spacing during firing. Not only is the spacing between adjacent bungs attained for the vertical flow of the kiln gases, but the shape of the bosses is such that cross channels are afforded through which the gases may pass horizontally. Even firing is thus positively insured, since the gases have free access to all portions of the saggerside walls.
The arcuate contour of the bosses reduces the likelihood of injury incident to handling, while the sloping lower portions reinforce them and add to their strength.
The lineal or circumferential extent of the bosses may be Varied, but I prefer to make them of considerable extent, not only for the sake of strength to insure their functioning, but also to allow for some latitude in the location of adjacent bungs.
lVhile I have shown my invention applied to a substantially rectangular sagger, it may be applied with equal utility to saggers of circular, oblong, oval or other shape. With the understanding therefore that the construction shown is merely illustrative of the underlying thought which I claim as my invention, I olaim- 1. A one-piece sagger having circumferentially-extending integral bosses spaced at intervals around the side walls of the sagger, and having a vertical extent substantially less than the depth of the sagger, said bosses serving as spacers between the saggers of adjacent bungs to insure both vertical and horizontal circulation channels for kiln gases during firing.
2. A sagger having adjacent the upper margin of its side wall, an arcuate circumferentially-extendin boss, the lower portion of said boss being inclined toward and merging in the said wall above the base thereof. 5
3. A bung comprising saggers, each of which is provided with a series of lateral bosses serving to space the same fIOIl'l the less than the depth of the sagger to afford both Vertical and horizontal circulation channels for kiln gases during firing. 10
In testimony whereof I hai e signed my name to this specification.
LORENZO o. BUGKLEY.
