SECTIONAL CAST-METAL DOOR WITH INTERCHANGEABLE PARTS.
Specication of Letters Patent. Patented June 18, 1918.
Application led December 4, 1914. Serial No. 875,484.
To all whom t may concern:
Be it known that I, WALTER L. CONWELL, residing at Montclair, New Jersey, and being a citizen of the United States, have invented certain new and useful Improvements in Sectional Cast-Metal Doors with Interchangeable Parts, of which the fol.
lowing is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and to use the same, reference being had to the accompanying drawings, which illustrate the preferred form of the invention, though it is to be understood that the invention is not limited to the exact details of construction shown and described, as it is obvious that various modifications thereof will occur to persons skilled in the art.
In said drawings:
Figure 1 is mainly a side elevation of the door, but is considerably broken away to show a vertical central sectionthereof.
Fig. 2 is a transverse vertical section taken on line 2 2, of Fig. 1, intermediate portions being broken out.
Fig. 3 is a similar section through a joint in the upper intermediate rail, and is taken on line 3-3 of Fig. 1.
Fig. 4 is a horizontal-section through vone of the stile sections adjacentk one of the removable panels, and is taken'on line 44 of Fig. 1.
Fig. 5 is similar view through a stile section adjacent the lower fixed panel, and is taken on line 5-5 of Fig. 1. A
Figs. 6, 7 and 8 are detail views of one of the upper corner pieces, Fig. 8 being taken on line 8-*8 of Fig. 6.
Figs. 9 and 10 are detail views of one of the upper intermediate connection members.
Figs. 11 and 12 are like views of one of the lower intermediate connectionfmembers.
Figs. 13, 14 and 15 are detail views of one of the lower corner pieces, Fig. 15 being Jraken on line 15-15 of Fig. 13.
Fig. 16 is a side elevation of one of the upper intermediate connecting stile sections; and
Fig. 17 is a similar viewfof one of the lower connecting stile sections.Y
Wooden stock doors are an established commercial commodity of highlyl appreciated value, and it isv a purpose of my present invention to produce a metallic door which may not only be kept in stock in recognized standards, but which may, to meet sudden and unusual demands, be quickly but wellY constructed in desired sizes and forms by the mere assemblage of stock parts.
It is also an object to construct the parts of a light and non-corrosive material, whereby the door possesses inherent qualities, suiting it to be exposed to the elements, and, when of massive dimensions to present an `imposing appearance, or for other purposes, permitting it to be easily moved.
' Another advantage is its knock-down characteristics, allowing'it to be shipped in the most advantageous manner.
The panel design and the number of panels may be optional, it requiring only the selection of correctly dimensioned and formed parts and the arrangement thereof.
Other advantages becoming manifest hereinafter are manifestly a part of this invention and are to be so construed.
In the drawings, which illustrate a door with cast metal parts, 1 represents the upper corner pieces of the door and 2 the lower corner pieces, the former each having top .rail and stile portions, and each lower corner piece being provided with bottom rail and stile portions.
Upper intermediate connection members 3 each have stile and intermediate rail portions, as do. the lower intermediate connectiony members 4.
`Complementary stile sections 5 are employed in connection with removable panels 6 and are present betweenY upper corner pieces land upper intermediate connection members, and also between the latter and lower intermediate connection members 4.
Other complementary stile sections 7 are used in conjunction with permanent panels 8l and are shown as connecting lower inter-l mediate connection members 4 with lower corner pieces 2.
Joining the upper corner pieces 1, is a top rail section 9 suited to the removable panel 6, and between the removable panels 6` is located a double intermediate paneladmitting section 10, uniting upper intermediate connection members 3.
Between the lower removable panel 6 and permanent panel ,8 is a combination paneladmitting and panel-embracing section 11, coupling lower intermediate connection members 4, and appropriatelyailiated with both the removable and permanent panels, 6 and 8, respectively.
Connecting the lower corner-pieces 2 is a bottom rail section 12 formed for association with the stationary panel 8.
Corner- pieces 1 and 2," intermediate connection members 3 and 4, complementary stile sections 5l and 7, top rail section 9, duplex rail section 10, combination rail section 11 and bottom railmsection 12, are all cast metal members, and are preferably hollow, as shown, to insure the door against excessive weight. lVhere, however, unusually heavy doors are desired, as for vault entrances, and the like, these parts may be solid, and their transverse sectional dimensions may be reduced or increased to determine the strength of the door.
Further lightness is given the door by forming it of metal having a lowV speciiic gravity, and ity will possess inherent protective qualities against the elements if said material is also non-corrosive. To acquire these properties, I prefer to use an alinni num alloy, one commercially known as aero metal, being excellently adapted to the purpose. Other alloys or metals may be used, however, in constructing theI door, and, when the latter is to have exceptional strength for protective purposes, cast steel is more suitable.
Stile sections 5 and 7, and rail sections 9, 10, 11 and 12 are illustrated as being hollow prismoids, the opposite ends or each being shaped to form a mortise. Distinguishing details of the various sections will be described hereinafter.
Each of the corner- pieces 1 and 2 and the intermediate connection members 3 and 4 is provided at its opposite ends with tenons 13, adapted to fit within the ymortises of the stile and rail sections associated with it. Said tenons 13 and the mor-tise portions of the stile and rail sections 5, 9, 10, 11 and 12 contain perforations or drilled holes for rivets orscrews which lock the parts together. In some instances, however, the joints may be welded instead of riveted. It is to be noted that said Vjoints also serve to brace the door trame.
Those edge, portions of the corner. pieces, stile and rail sections and the intermediate connection members, which coperate to surround panels, are preferably beveled or given the contour of a classic molding, improving the appearance ofv the door, and the beveling or. molding contour may be on either or both sides of the door.
Upper cornerfpieces 1, top rail section 9, upper stile sections 5, upper intermediate connection members 3 and intermediate duplex rail section 10 Surround the upper removable panel 6, while said upper-V intermediate Connection members 3,. intermediate duplex rail@ .Secties l0, 0tl1e1- intermediate Corner-pieces 1, upper intermediate connection members 3 and the upper portions of lower connection members 4 are provided with pads or bosses 16, and flanges 17, which, taken together, are of the `Same cross section as the combined ridges and ianges 14 and 1,5, and are alind therewith. Be-
tween pads o r bosses 16. of said upper cornerrpieces and intermediate connection members are corev openings 1 8, communicating with the interior of these parts.
A-lined ridgesy 14 and pads orbosses 16, and also their respective alined iianges 15 and 17, form panelfreceiving depressions for' the removable panels 6, and the cushioning strips 19 therefor. After the panels 6 are inserted into their depressions, they are held in place by retainingl strips or frames 20, secured to the ridges 14 and pads or bosses 16 by screws or other suitable means.
The. contiguous sides of stilevand rail sections, intermediate connection members and corner-pieces which surround a permanent panel, in the present instance the lower side of the intermediate combination rail Seotion 11, stile sections 7, bottom rail section 12 and the.y por-tions of lower intermediate connection members. 4 and lower cornerpieces 2, which connect said stile and rail sections, are each provided with spaced par- 211181 anses 2.1, adapted to, lap; and embrace the borders of a permanent panel 8;. Rivets or. othery devices pass through flanges 2l and the inCaSed borders of permanent panel 8 securing said panel in place. Instead of being riveted, the flanges, obviously, may be welded to the panel borders,
It is to be understood that the door show-n in the drawings is but. one embodiment ofmy invention, andv that the various door elements may be arranged to produce vertically disposed intermediate connection members similar to members 3 or 4, will result in a door having mullions. In fact, a Wide range ofy different combinations is possible. Also, the various sections may be perforated or left open in various locations for the insertion of door lixtures, such as locks, door hangers and other accessories.
