HARRY E. DE VAUGHN, OF MORGANTOWN, WEST VIRGINIA, ASSIGNOR TO WALTER A.

JONES, OF MOB/GANTOWN, WEST VIRGINIA.

GLASS-FURNACE.

Specification of Letters Patent.

Application filed October 6, 1918. Serial No. 124,091.

To all whom it may concern:

Be it known that I, HARRY E. DE VAUGHN, a citizen of the United States, residing at Morgantown. in the county of Monongalia and State of West Virginia. have invented new and useful Improvements in Glass- Furnaces, of which the following is a specification.

This invention is an improved suspension device for use in glass furnaces. and other glass handling apparatus generally. wherein the parts are subjected to intense heat.

()ne of the objects of the invention is to provide a simple device for supporting rcfractory or silica walls, arches. or other construction. A further object is to provide a device of this character and means for protecting the same from destruction by the intense heat to which it is subjected in operation.

The invention will be hereinafter fully set forth and particularly pointed out n he claims.

In the accompanying drawings Figure 1 is a front elevation of the skew block of a glass furnace. with the invention applied thereto. Fig. 2 is a vertical sectional view thereof. Fig. 3 is a similar sectional view taken at right angles to Fig. .2, Fig. l is a bottom plan view of the skew block. Fig. 5 is a top plan view of the suppor ing device. Fig. (i is a view illustrat ing the' .vcnt ion up plied in suspending the clay mantel walls of a flattening or annealing oven.

Referring to the drawings, l0 designates a skew block of the type usually employed in supporting the cap of a glass furnace, said skew block. in the form illustrated in I igs.1,2and4.beingprovidcd in its bottom with a channel 11. leading in from the rear wall thereof. the walls of said channel being in lined as indicated at 12. to accommodate the undercut edges ol a protector block 13. Leading upwardly from the channel It into the body of the skew block. is a recess H. which cinnmunicates with bores l5. ding to the top of the block. Located Willlh: the recess 14 is a supporting device Ill. prct'prably constructed of metal, and provided \\'Illl 'an' internal chamber 17. and top and bot tom threaded openings 18 and Hi respectivcly, the openings '19 bring in the bottom wall and of smaller diameter than the openings 18, which are formed in the top Wall. Suspension rods 20, having their upper end supported in any suitable manner, are attached to the threaded openings 19, passing through the openings 18, and by reason of the engagement with the supporting member 16. and the supporting means for the rods 20. not shown, the skew block may be suspended over the molten glass. Surrounding the rods 20. and engaging the threaded openings 18 are pipes 21, one of said pipes being connected to a. source of supply, and the other pipe to a discharge branch. whereby a cooling medium, such as Water, may be caused to circulate around each of the rods 20 and through the chamber 17, thereby protectiug the metal parts from'the intense heat radiating from the molten glass, and from other sources.

In practice. the suspension rods 20, and the pipes 21 are first. attached to the supporting member 16. and then said pipes and Said rods are passed upwardly through the bores 15. the suspension rods being connected with the supporting device in any suitable way.

The protector block 13 is then placed in position. by sliding the same into the channel 11. the undercut edges of said protector block and the inclined walls of said channels, serving to maintain the protector block in position. so as to completely cover the supporting device 16. and thereby serve as an additional protect ion therefor.

In Fig. 3. in lieu of the protector block 13. a float 25 is employed. the same having a reduced portion 26. shaped to enter a recess 27 in the bottom of the skew block 10. In practice the tloater block 25 floats upon the surface of the molten glass. and by reason of th lHHKYHHU t" thereof. the reduced portion 2a is held within the recess 27 of the skew block. thereby covering the supporting member 16. and being also held against relative disphu-ement.

In Fig. 6 the suspension device is shown as supporting the clay mantel Walls 30 of a flattening or annealing oven. said walls being provided with recesses 31 to receive the supporting devices 16. the suspension devices being passed through the mantel walls and the cap or crown of t oven. the iods 20 having their upper ends secured to a supporting beam 3:3. sustained in any desired manner.

Having thus explained the nature of the invention, and described an operative man nor of constructing and using the same, although without attempting to set forth all of the forms in which it may be made, or all of the forms of its use, the following is claimed 1. A suspension device of the character described comprising a Hat supporting device provided with a closed chamber, suspending means rigidly secured to said supporting device, and means for guiding a cooling medium into and out of said chamber and in contact with said suspendii'ig means.

2. A suspension device of the character described comprising a flat supporting de vice provided with a closed chamber, suspension rods rigidly attached to said supporting device, and cooling devices sur rounding said rods and communicating with said chamber.

3. A suspension device of the character described comprising a flat supporting de' vice provided with a closed chamber, suspension rods extending through said chamber and having threaded engagement with the bottom Wall thereof, and tubes surrounding said rods and having a threaded engagement with the top wall of said chamber and communicating therewith.

4; The combination with a body of refractory material having a recess in its underside, a supporting member located within and substantially filling said recess, suspension means for said su porting member cxtending through said )ody, and means for cooling said supporting member and its sus pension means.

5. The combination with a body of refractory material having a recess in its underside, a supporting member located within said recess, suspension means for said sup porting member, and a refractory member for closing said recess.

6. The combination vvith a body of refractory material having a recess in its underside, of a flat supporting member located within and substantially filling said recess, said supporting device being provided with a closed chamber, suspension means rigidly secured to said supporting device, means for guiding a coolin medium into and out of said chamber an in contact with said suspension means, and a refractory member closing said recess and covering said sup porting member.

7. The combination with a body of. rei'rars tory material ha ing a channel in its under side, and a iecess leading upwardly from said hannel, of a sug'iporting member lo cab-d within said recess, suspension means for said supporting member leading through said body, and a protector block located in said channel and covering said supporting member.

8. The combination with a body of refractory material having a channel in its under side and a recess leading upwardly from said channel, of a fiat supporting device 10- catcd Within and substantially filling said recess, said supporting device being provided with a closed chamber, suspension means rigidly secured to said supporting device, means for guiding a cooling medium into and out of said chamber and in contact with said suspension means, and a protector block located in said channel and covering said supporting member.

In testimony whereof I have hereunto set my hand in presence of two subscribing wit nesses.
