DOOR FOR DRY-KILNS.
SPECIFICATION forming part of Letters Patent No. 657,532, dated September 11, 1900.
Application filed March 16, 1900. serial No. 8.929. (No model.)
T0 au whom it may concern.: n
Be it known that I, THOMAS GREEN, a citizen of the United States, residing at Wabash, in the county of Wabash and State of Indiana, have invented certain new and useful Improvements in Doors for Dry-Kilns, of which the following is a specication.
Myinvention relates to doors for dry-kilns, the object being to provide a door of light durable construction which maybe manufactured at smallcost and operated as a hoisting-door with little labor and which will prevent the escape or radiation of heat.
The construction of the invention will be fully described hereinafter in connection with the accompanying drawings, which form a part of this specication, and its novel features will be defined in the appended claims.
1n the drawings, Figure 1 is a front elevation of a door embodying the invention. Fig. 2 is a vertical section on the line 2 2 of Fig. 1. Fig. 3 is a transverse section on the line 3 3 of Fig. 1. Fig. 4 is a transverse section on the line 4 4 of Fig. 1, and Fig. 5 is a section on the line 5 5 of Fig. 1.
The rectangular frame of the door cornprises vertical bars l, connected at top and bottom'by transverse bars 2 and 3, which are each formed on their inner sides with equidistant recesses 4, within which are secured 4 the ends of parallel vertical strips 5, consti- 'to the cross-bars 2 and 3 by parallel transverse bars 8, which are formed with equidistant recesses 9, withinwhich the strips 7 iit and are alined horizontally with the outer cross-bar 6. Between the two sets of vertical overlapping strips 5 and 7 is interposed a sheet 10 of asbestos, which is irmly clamped between the front and rear strips.
11 designates a central longitudinal bar on the outer side of the door, secured at its lower end to the lower cross-bar 2 andV extending through a slot formed in a horizontal iiange 12, projecting from the upper cross-bar 3 of the door-frame. The projecting upper end 13 of the bar 11 is slotted to receive a wedgekey 14, which secures the bar firmly to the door. The rear side of the bar 11 is formed with a. series of recesses 15, through which the cross-bars 6 extend, and the outer side of the bar 11 is provided with an oppositely-inc lined reinforcing projection 16, slotted at the points 17 and 18 for the sake of lightness in construction. The bar l1 is braced to the upper cross-bar 43 by oppositely-disposed inclined braces 19 and 20, the lower ends of which are recessed to overlap each other and extend through the upper slot 17 of the bar l1, while their upper ends are recessed to fit the upper cross-bar 3.
Any suitable means for raising and lowering the gate maybe provided, the hoisting means not forming a part of the present invention.
As thus constructed the parts of the door are firmly secured together, and the sheet of asbestos is firmly clamped between the outer and inner vertical strips. The asbestos confines the heat and prevents its escape by radiation, and thus materially contributes to the eectiveness of the kiln.
I claim- 1. Adoor for kilns, comprisingafraine consisting of vertical and transverse bars; a se- .'ries of parallel vertical strips on the outer side of the door; transverse bars secured to said strips; a series of parallel vertical strips on the innerside of the door alternating with the outer strips and breaking joints therewith; and a sheet of asbestos interposed between the outerand inner strips, and clamped in place thereby.
p 2. Adoor for kilns comprising a rectangular frame; a series of outer vertical strips; a series of inner strips overlapping and alternating with said outer strips; a sheet of asbestes clamped between the two series ofstrips; transverse securing-bars for the outer strips, and acentral longitudinal barsecured to the outer strips of the door.
