METALLIC CEILING.

SPECIFICATION forming part of Letters Patent No. 406,049, dated July 2, 1889.

Application filed November 18, 1888. Serial No. 291,064. (No model.)

T0 66 whom it Huey concern.-

Be it known that I, WILLIAM R. KINNEAR, a citizen of the United States, and a resident of Columbus, in the county of Franklin and State of Ohio, have invented new and useful Improvements in Metallic Ceilings, of which the following is a full and exact description, reference being had to the accompanying drawings, making part of this specification.

This invention relates to improvements in metallic ceilings, and has for its objects to suspend the same directly to the building structure, to so join the panels or parts com posing the ceiling that a portion of the weight of each is suspended by the adjoining panel or part, to provide suspending devices which are easy of manipulation and allow of rapid adjustment, and to disguise the suspending devices by incorporating them in the ornamentation.

111 the drawings, Figure 1. is a plan view of a section of the ceiling with this invention applied thereto. Fig. 2 is a section of the same, showing the ceiling as applied to a wooden building structure. Fig. 3 is a detail view in section of the ceiling as applied to an iron building structure. Fig. i is a detail the panels composing the ceiling shown in Fig. 1 with one form of the suspending devices, the parts being separated to show their application. Figs. 5 and (3 are detail views in section of the lapping margins of the said panels joined by alternative forms of suspending devices. Fig.7 is a detailviewin section showing an alternative form of hanging the ceiling to a metallic structure.

The letters X designate the floor-beams of the building structure to which I apply the ceiling, whether it be a wooden structure, as shown in Fig. 2 of the drawings, or metallic, as shown in Fig. The form of panels differs in these two forms only in the hanging-margins, which in the metallic structure I sometimes turn so as to form a hook to engage the flange at the lower edge of the same.

The panels A are stamped or otherwise formed from single metal plates and are provided with the margins 13 and C. The margins B'are provided with the same moldings that are placed on the margins C. At the outer edge they are provided with the upward extensions B, which rest against the structure to which the ceiling is to be applied. At this point the said extension is provided with the outwardly-extendin g flange B which rests firmly against the building structure or beams X thereof. The margins C rest or lap over the margin B, and are provided at their outer edges with the upward extension 0. This extension, by being turned upward, makes a joint with the margin B, which is turned away from the eye; and in some constructions, as those shown in Fig. 3 of the drawings, it forms abrace to hold the flange B on the same panel in position.

In the majority of instances, when. these ceilings are used, I place around the room acornice 1), which nailed to the sides of the room and is provided on two adjoining sides with marginal extensions corresponding to B and O of the panels and having the extensions 13 and G and flange B \Vhen the cornice is omitted, it is substituted by a brad, which is placed in position to receive the margin (E, or the extension 0 of the said margin is bentdown and the panels secured at those sides by nailing them to the sides of the room through the said extensions.

In hanging this ceiling the cornice and panels are put up with the flange 13 toward the operator. As each panel is placed in position, it is adjusted by placing the two adjoining margins C over the margins B of the adjoining panels. The operator then secures it in position by nailing through the flanges 13 on the two adjoining and exposed sides, and so on until all the panels are thus loosely attached, when the cornice having the extension corresponding to the margin 0 is set in position, with the said extension lapping the margins 13 of the adjoining panels, and nailed to the sides of the room at the bottom flange. The lapped margins are now secured by means of the suspending devices E, F, and G. (Shown in Figs. t, 5, and (3 of the drawings.)

The device E (shown in Fig. 4) consists of a small headed bolt passed through the face of the margin 13 with the head resting against the upper or inner surface of the said margin. The head is soldered firmly to the margin 13, so that in adjusting the next panel it will not be dislodged. The margins 0 are all provided with perforations so disposed as to fit over the threaded shanks of the devices E. WVhen they are so adjusted, the round buttons E are secured on the exposed shank and down against the margin 0, drawing it firmly against the margin B and suspending those sides of the panels to the said margins B of the adjoining panels. The margins are decorated by small bosses, as shown in Fig. 1 of the drawings, so that the button, corresponding as it does to the said bosses, is disguised as one of them and lost in the design. The design and decoration of these bosses may be varied to any extentwithout interfering with the construction as described.

The device shown in Fig. 5 consists of an elongated washer or nut F, which is passed crosswise through the margins B bymeans of slots in the sides thereof that are provided. The said nut is provided with a threaded perforation in line with perforations provided in the margins B and C, and which come together when the said margins are lapped. The nut is formed from wroughtiron or any suitable metal that may be turned at the ends, as shown in the drawings, to hold the nut in position during the adjustment of the panels.

\Vhen the panels have been adjusted, as above described, the metal screws F are passed through the perforations in the lapped margins and made to engage the threads in the perforation in the nuts F, when it is driven up until the head of the screw rests against the margin 0 and draws the same up against the margin 13, and thus supports those sides of the panels. The faces of the margins are decorated with rosettes F", into the center of which the heads of the screws F sink, and in the design of which they are lost, being disguised as part of the ornamentation.

The device shown at Fig. 0 is in the form of a key or wedge. It consists in the hook G with the head G. To receive the hook, the margins are provided with elongated perforations in line. IVhcn the panels have been adjusted, these devices are applied by pressing the margins together and passing the hook G into the perforations and over the margin B until the head G rests against the margin 0. If the device is not in this position as securely fastened as desired, small wedges may be driven under the heads until it is so. The shape of thehead, as in the other described devices, is formed to harmonize with the decoration of the said margins.

In the drawings, at Fig. 2 is shown a means for hanging the ceiling to metallic building structures, which consists in bending the flange B to form the hooked edge In operation this form of suspension depends upon the joining of the margins B and O, as by so joining the said margins the hooked edges are held firmly in position on the flanges of the beams X. In this construction, as in the others, the panels are adjusted with the flanges 13 next the operator, which are turned over the flanges then in order to make a snug fit, or are turned before beingplaced in position.

In Fig. 7 is shown a form of hanging the ceiling to a metallic building structure wherein the flanges are omitted at the lower edge of the beams X. In this case I use the suspending-hook II, (shown in the drawings,) the crook of which I pass over the beam and attach'to the lower end of the flanges 13 of the panels. The fastening at the lower end may be of any suitable description, so I do not confine myself to that particular form shown in the drawings.

WVhen the ceiling is suspended in any'of the ways above described,it is colored as de sired, and then presents a neat and pleasing appearance.

It is obvious that the forms of the elements of this invention may be varied indefinitely while accomplishing the same purpose in the same way. Therefore I do not confine myself to any of the said forms. In Fig. 4 of the drawings I have shown by means of the dotted lines Z the suspending-strips, by means of which the ceiling is suspended from the building structure. The suspending-strip, as shown by the line Z, may be of any shape which will still retain the flange B the extension B, and the part which passes under or engages the suspending devices. Further, it may be separate and not integrant with the margin B, which may not extend beyond the suspending devices that join thelapped margins of the panels.

\Vhat I claim is- 1. In a metallic ceiling such as described, the combination of panels provided at the sides with margins adapted to be fitted over the margins of the adjoining panels and having on one or more sides an extension which is secured to the building structure, and fastenings for securing the fitted margins together, the exposed parts of which are incorporated into the design and ornamentation of the said panels, substantially as described.

2. In a metallic ceiling such as described,

the combination of panels provided on thesides with the margins B and O, the extensions B, extending from the said margins B and secured to thebnilding structure, and fastenings to hold the said marg ns together, substantially as described.

3. In ametallic ceiling such as described, the combination of panels provided on the sides with margins B and O, the extensions 13, extending up from the said margins B, hooks engaging the beams of the building structure and attached to the said extensions, and fastenings to hold the said margins together, substantially as described.

In testimony whereof I have hereunto set my hand this 12th day of November, A. D.

WILLIAM n. KINNEAR.
