CASTING-TABLE roe PLATE-GLASS.
Specification of Letters Patent.
PatcirtedJune 3,1920.
Application filedfianuary 1S, 1919. Serial No. 271,853.
To all who 2n it may concern:
Be it known that I, FRANK E. TROUTMAN, a citizen of the United States, and resident of Butler, in the county of Butler and State of Pennsylvania, have invented a new and useful Improvement in Casting-Tables for Plate-Glass; and I do hereby declare the following to be a full, clear, and exact descripti on thereof.
My invention relates to casting tables for use inthe manufacture of fiat or plate glass. i The primary objects of my invention are to provide a table which has a minimum tendency to distortion from the action of the hot glass being rolled on its upper surface; to provide a' tablewliich will give uniform results at all times, and a table whose cost of upkeep and maintenance is reduced to a minimum.
In the drawing Figure 1 is an end View of myimproved table; Fig. 2 is a crosssection on the line 2-2 Fig. 1; Figs. 3 and l show modified forms of my invention, and Fig. 5 is a side view partly in section to show the end connections.
The present casting tables are generally made up of a number of long sections bolted together, and bolted to a foundation stand. They are provided with pipes cast in the sections more or less close to the upper surface for the passage of water for cooling the sections during the casting operation or the heating of them preparatory to use. One of the chief difficulties in the useof the present form of casting tables is due to the fact that the upper portion of the table will be cooled by the water in the pipes, but the lower portions will be prevented by these same pipes from getting the proper amount of heat, hence the upper portion of the table becomes relatively much hotter than the lower portion, resulting in an unequal expansion of the parts of the table. This unequal expansion will cause warping or deformation and consequently the glass formed thereon is defective. Furthermore this action tends to cause a longitudinal movement of the sections as the table is alternately heated by the hot plate of glass or cooled by the continuous passage of the water.
My'invention consists generally stated in providing for the passage of the water or other cooling or heating medium not only adjacent to the upper surface of the table, but
also in the lower portion, whereby the table is kept approximately at a constant temperature throughout its entire body.
In the drawing the numeral 2 designates a casting table made up of sections 3 formed of cast iron or other suitable metal. These sections are keyed together by keys 4t which fit in adjoining key-ways 5, and the sections are subsequently bolted together by bolts 6. The adjoining faces of the sections are so formed that when united by the keys and bolts the passages 7 are formed at the joints of the sections. This is the common method of uniting the sections and does not involve any part of my invention. y In the upper portion of the plate, or the different sections thereof, are the pipes 8 which are preferably cast integrally with the sections extending entirely through said sections. The lower portion of the plate or sections is also provided with pipes 9 and these pipes are connected at one of their ends by the connections 10, so that water admitted by the pipes 11 passes through the pipes S and by the connections 10 to the pipes 9 to be carried off by the pipes 12.
To provide proper means for connecting the connections 10 to the pipes 8 and 9 to prevent leakage, I provide the flanges 18 which are bolted to the planed-off faces 14: of the table said flanges having the collars 15 into which the connections 10 are fitted. This arrangement provides a perfectly tight joint and one easily renewable and accessible for cleaning out the pipes.
The table is supported on the standards or supports 16 and in order to prevent the longitudinal movement of the sections, the table is provided with the tongue 17 at or near its center which fits into a seat 18 in one of the standards 16. This construction permits of the vertical movement of the table but prevents longitudinal movement.
When the table is used for a casting the water passing through the pipes 8 will act to cool the upper portion of the table and said water becoming heated in its passage through said pipes will pass to the pipes 9 and in its passage through said pipes will tend to heat up the lower portion of the table, and thus act to keep the table approximately at a constant temperature throughout its entire area. In case, however, the upper portion of the table should become slightly warmer causing it to expand somewhat more than the lower portion, the result .17 fitting in the seat 18.
A further advantage of my improved table is that the table may be kept at the proper casting temperature before the glass is deposited on the table by running hot water through the pipes 8 and 9, thereby keeping both the upper and lower portions of the table at the same relative temperature.
By equalizing the temperature of the table in this manner, the strains and stresses due to unequal heating are eliminated, and the life of the table greatly increased.
In Fig. 3 I have illustrated a modified form of my invention in which the pipes 19 are cast in the form of grooves which are closed by the plates 20 secured to the bottom of the sections.
In Fig. 4 I have illustrated another form of my invention in which the upper portion of the plate projects beyond the lower por* tion, and an elbow 21 is used for connecting up the pipes of the upper portion with the pipes of the lower portion. In this construction the connections between the upper and lower pipes are not exposed in position to be struck or injured.
What I claim is:
1. A casting table for plate glass having passages for the cooling and heating medium, said passages being arranged in the plate at different heights and connected at their ends.
2. A casting table having a surface for the hot glass, means for cooling the upper portion of the table, and means for heating the lower portion.
3. A casting table, a support therefor, and a tongue and groove connection between said table and support.
In testimony whereof I, the said FRANK E. TROUTMAN, have hereunto set my hand.
FRANK E. TROUTMAN.
