PATENT OEEICE.
SAMUEL PRICE STEVENSON, OE CHESTER, PENNSYLVANIA.
DOOR-FRAME FOR AIR-TIGHT DOORS..
SPECIFICATION forming part of Letters Patent No. 794,953, dated July 18, 1905.
i Application filed June 27,1903. Serial No. 163,405.
To all whom, t may concern:
Be it known that I, SAMUEL PRICE STE- vENsoN, a citizen of .the United States, residing at Chester, in the county of Delaware and State of Pennsylvania, have invented certain new and useful improvements in Door-Frames for Air-Tight Doors, of which the following is a specification.
This invention relates to door-frames for air-tight doors, and more particularly applicable to those used for cold-storage apartments, and has for its object the providing as a commerciall article of manufacture such door-frames of greater durability and improved facility of entrance and exit with objects or commodities to be stored with the briefest duration of opening of the door.
To this end this invention consists in animproved construction of frame and casing combined with a specially formed and attached construction of sill and threshold, to which doors are readily applied with airtight closure and which aord a firm and durable support for the hinges of the door, such frames being made and shipped complete as articles of manufacture and applicable without alteration to the doorway-openings of air-tight apartments. The construction of this door-frame is shown in the accompanying drawings, in which- Eigure l shows a front elevation of a doorfraine embodying my invention; Fig. 2., aside elevation; Fig. 3, an inverted ground plan; Fig. 4, a top view; Fig. 5, a vertical section, and Eig. 6 a horizontal section in the plane fc ff; in Fig. l.
The door and hinges are shown in dotted lines in Fig. 1.
Referring to the drawings, 1 and l' are door-jainbs.
2 is a lintel, and 3 the sill with an inclined threshold 4, formed integrally therewith in front of the door. The sill 3 is fitted between the lower ends of the jambs l and l', and the casings 5 also extend below the upper surface of the sill 3 and are secured between projections 6, formed on the sill and threshold. The front edge of the threshold is of such thickness as when let into the floor as to leave the base 7 of the inclined surface 4 Hush with upper surface of the floor 8. rIhe casings 5, being held in the manner above described, are well adapted to support the pivots of the extended hinges 9, upon which the door lO is hung. The upper ends of the jambs 1 and l' are preferably tongued and grooved into the lintel 2.
By reason of the thickness of the front edge 7 of the sill 3, forming the threshold, it is stronger and well adapted to endure handling without injury in transportation and when erected to stand the impact of Wheeled trucks entering and leaving the air-tight chamber and effectually clears the lower edge of the door lO when open.
Door-frames as thus constructed are easily erected in the doorway-openings of air-tight apartments and are sufficiently flexible in torsional directions to be readily sprung into wind to conform to any winding or twisting of the door to be used in conjunction therewith and when so sprung may be held in place by nailing fillet-strips to abut against the inner edges of the frame. The sill furnishes a firm bracing and support for the jambs 11 and casing 5.
Having described my invention, what I claim is- In a door-frame for air-tight apartments of refrigerating and like buildings, the combination of a threshold having a sill integral therewith and provided with lateral extensions projecting beyond the doorway at the front, or opening face thereof; extended casings projecting below the upper surface of said threshold and secured against the rear faces of the projecting portions thereof; jambs extending below the upper surface of the threshold and secured to the ends thereof in rear of said casings; and a lintel connecting said jambs and casings at the upper extremity of the doorway, substantially as set forth.
