(Cl. 10S- 1) 8 Claims.
My invention relates to building structures and more particularly to the cornice construction for buildings of the character to which it may be desired to add an additional story.
Many homes and other building structures are now built with the intention of subsequently adding one or more stories thereto. Inl existing structures this can only be accomplished by breaking away substantial portions of the roofs and sides thereof with the result that the interior of the structure is exposed to the weather during the construction of the new unit.
The principal object of the present invention is to provide a cornice of such construction that by merely removing a portion thereof access may be had to the top of the walls of an existing structure to enable the walls of a new story to be built thereon without disturbing other parts of the existing structure.
Important and essential features of the invention, residing in advantageous forms, combinations and relations of parts, will hereinafter appear and be specifically pointed out in the claims.
In the drawings, illustrating a preferred embodiment of the invention,
Figure 1 is a perspective View, partly in section and partly in elevation, of the upper corner of a building structurev having my improved cornice.
Figure 2 is a transverse vertical sectional view of the construction illustrated in Figure 1, the cornice cap and roofing paper being omitted.
Figure 3 is a longitudinal sectional view through the cornice with the side plate of the wall in elevation.
Figure 4 is a fragmentary sectional View of the inner member of the cornice in the shape in which it is originally applied to a building construction.
Figure 5 is a fragmentary perspective View of the strap which assists in supporting the inner member.
Figure 6 is a perspective view of a portion of one of the hangers or supports for the cornice.
Figure 7 is a perspective View of another portion of one of the hangers or supports for the cornice.
Figure 8 is a perspective view of er or support for the cornice.
Figure 9 is a fragmentary perspective View of the outer member of the cornice.
Figure 10 is a fragmentary perspective view of the bar employed for securing the roofing paper to the outer member of the cornice.
For purposes of illustrating the invention, a
another hang- -at their upper ends by a wooden or frame building has been chosen but it will be apparent as the description proceeds that the invention is equally well suited for use with other kinds of buildings, such, for example, as those having metal, stone and cement walls and also for use with prefabrlcated or factory built wooden houses.
Referring more particularly to the drawings, I indicates the side wall of a wooden or frame building which has studs or uprights 2 connected plate 3. The outer side of the wall is shown as being provided with a sheathing 4 and siding 5.
Supported by the plate 3 are joists 6 which serve as a support for the roof 1. A sub-floor 8 is preferably secured to the top of the joists 6 and building paper 9 may be advantageously interposed between the sub-flooring and the roof.
The roof is preferably formed in sections of such size as may be conveniently handled by workmen. Each roof section is of ramp-like form so as to have a slope of the degree necessary to cause water to drain to the side edges of the roof. Such ramp-like sections may be conveniently formed with boards of such size as 2 x 4', 2' x 6 or 2 x 8 which are split diagonally from corner to corner, the dimension of the boards employed depending upon the slope which it is desired the roof to have. These boards are connected by suitable sheathing I I over which is laid roong paper I2 which may be preferably tarred and gravelled.
The cornice construction parts, an outer member I3, an inner member I4 and a cap i5. The outer member is designed to overlap the upper portion of the adjacent side wall of the building and to extend upwardly above the roof. Adjacent the corners of the building the outer member I3 may advantageously be firmly secured in place by a pair of brackets I6 and Il' which, in the embodiment'of the invention, may be connected to the outer end of the joists These two brackets are secured in overlapping relation to the top of the adjacent joist comprises three main l and bracket I6 has a downwardly extending por-` tion I8 which extends into an upwardly opening groove I9 formed in the lower portion of the outer member I 3 while bracket I1 has an upwardly extending portion Z0 which fits into a downwardly opening groove 2! which is provided by a reversely bent portion in the upper part of the outer member. By thus cooperating with the outer member,` the brackets I6 and I1 serve to hold it rigidly in place with its lower edge against the wall without the necessity of employing any additional connecting orA fastening means. M
The inner member I4 of the cornice comprises an inwardly extending portion 22 adapted to overlap the roof and a portion 23 which extends upwardly therefrom. The portion 23 preferably extends upwardly to the height ofthe outer member I3 and it is folded upon itself to provide two legs 24 and 25, respectively. A longitudinally extending strap 26 is interposed between the legs 24 and 25 and it, together with the leg 24, is rigidly connected by screws 28 to the upper end of an upright portion 21 of bracket I6.
The inner member I4 which is made of some flexible material, such as copper, is applied to the roof before the roofing paper I2 is put on and as originally applied it may advantageously be in the form shown in Figure 4. After the strap 26 has been inserted between the legs 24 and 25 and the strap and leg 24 have been connected to bracket I6, leg 25 is then bent inwardly into substantial parallelism with leg 24, as shown in Figure 1. To hold it in this position the outer edge of portion 22 of member I4 which is interposed between the roofing paper I2 and the roof sections 1 may be tacked or otherwise secured to the roof.
The upwardly extending portion 23 of the inner member is spaced inwardly from the outer member I3 so that an open space is provided directly above the top of the wall through which access may be had thereto. The distance between these laterally spaced portions of the cornice is suiiicient to permit materials for the walls of a new story for the existing structure to be readily inserted between them for connection to and support by the existing walls. In the particular embodiment of the invention illustrated, it will be seen that ample space is provided between the inner and outer members of the cornice through which studs (shown in dot and dash lines in Figure 2) for the walls of the new story may be inserted in order to be supported by the plate 3 and be connected to the joists E.
To close the space between the inner and. outer members of the cornice and thus render it watertight an inverted channel-shaped cap I5 having downwardly extending legs 29 is preferably employed. Before the cap is applied, however, the roong paper is preferably extended across thel space between the outer and inner members I3 and I4 and its outer edge may be advantageously secured to the outer member` by clamping it within an upturned groove 3I by a longitudinally extending bar 3| provided on its inner face with suitable teeth or roughened portions for gripping the'roong paper. The cap may be conveniently secured in place over the roong paper by screws 32 which extend through threaded openings in the bar 3l.
While it is preferred to use the brackets I6 and I1 together to secure the outer member I3 in place at the corners of the building the remainder of the member may be adequately secured by using brackets I6 on alternate joists and brackets 33 of the character illustrated in Figure 8 on the intervening joists. The bracket 33 has an upwardly extending portion 34 for cooperating with the upper portion of the outer member I3 and another upwardly extending portion 35 for attachment to the portion 23 of the inner member I4.
Water collecting on the roof may be easily drained therefrom through a conduit or pipe which at its inner end extends through suitable openings in the legs 24 and 25 of the inner member I4 and which at its outer end is connected to the upper end oi a section of a downspout 31 which is soldered or otherwise secured to the outer face of the outer member I3. The conduit 36 is preferably connected with the outer member I3 before the latter is put in place so that in assembling the cornice on the building only the inner end of the conduit need be soldered to the inner member I4.
As is plain from the foregoing, all that is required to gain access to the top of the walls of the existing structure in order to erect thereon the walls of a story to be added to the structure is to remove the cap I5 of the cornice and the portion of the roofing paper I2 which underlies the cap. The weather tightness of the structure need not be otherwise impaired during the construction of the new unit and, when that unit is made Weather-proof, the remaining parts of the cornice and the roof sections of the original structure may be removed and subsequently used again.
Such modications in details of construction as may be necessary to adapt the particular embodiment of the invention herein illustrated and described to buildings having walls of metal, stone, cement or other wooden construction will readily suggest themselves to those skilled in the art and are Within the purview of the invention as deiined in the appended claims.
