SPECIFICATION forming part of Letters Patent No. 298203, dated May 6, 188%.
Application filed August 11, 1883. (No model.)
To all whom, it .may concrn:
Be it known that I, EDWIN WILLIs HIcK- MAN, .of Bay View, in the county of Milwaukee and State of Wisconsin, have invented a new and useful Improvement in Cooling-Shields for Puddling and Heating Furnaces or for any Surface of Heat, of which the following is a specification.
My invention relates to shields for furnacedoors, and will be fully described hereinafter.
In the drawings, Figure l is a perspective View of a portion of a furnace with my shield in place. Fig. 2 is an enlarged perspective view of my shield. Fig. 3 is a detail, and Fig. 4 is a longitudinal section, 'of my shield.
A is the shield, and B is the furnace. The shield A is made hollow, withclosed ends and edges, and with a pipe, G, entering it at one lower corner, and another pipe, D, leading out of it at or near the corner diagonally opposite that in which the pipe O enters, and near its center the shield has -an opening that is closed by a door, E. one side, and' on the other has an ordinary hasp that engages with a staple on the shield, and is secured thereon by a pin, F. The door is re-enforced near its center at G, and through- This door is hinged on` air blast, as it is immaterial. whether cold water or air be used, and the air or water is forced from pip'e G through the shield and out through pipe D, thus keeping up a constant circulation, by which the heat from the furnace is carried off. The shield A is secured to ver- 0 curing it in place by pin F, and then screwing' bolt H in against re-enforce K on the furnacedoor.
'What I claim as my invention, and desire to secure by Letters Patent, is-
1. In a hollow shield for furnaces, a door provided with a screw-bolt for screwing the furnace-door to its seat when closed, substantially as described.
2. The shield-door and mechanisn for securing it when closed, in combination with a screw-bolt, H, and furnace-door, as set forth.
3. A hollowshield adapted for containing air or water in circulation, and having a door forgiving access to the furnace-door, in combination with a brace for pressing the furnacedoor tightly in place when the shield-door is closed, 'as set forth.
