CEILING-PLATE.

Specification of Letters Patent.

Patented Jan. 16,1917.

Application fi led April 15, 1913. Serial No; 761,239.

invention, among others, is to provide a device of this class, extremely simplein its construction and requiring a. minimum expense in its production, and at the same time one extremely effective for accomplishing the purpose for which it is intended.

One form of device embodying my invention, and in the construction and use of which the objects above set out, as well as others may be attained, is illustrated in the accompanying drawings, in which- Figure 1 is a view in side elevation of a portion of a pipe showing my improved ceiling plate attached thereto, the latter being cut away, on plane denoted by dotted line 11 of Fig. 2. Fig. 2 is a plan view of the inner face of my improved ceiling plate, showing the parts closed. Fig. 3 is a like view showing the parts open, and'illustrating a modified form of tongue.

In the accompanying drawings the numeral 5 denotes a pipe of the kind usually employed for conducting fluids of various kinds, as water, air or the like, such pipes commonly extending from one room through an opening in the ceiling thereof, said pipe being supplied with my improved ceiling plate to cover and conceal said opening. This plate consists of two sections 6, 7 of semi-annular shape, constructed to closely fit each other at their meeting ends 8. The

plate 7 has a hinge member 9 consisting of a projection formed from the material originally composing the central part of the sheet metal blank from which the semi-annular section is formed, said projection being formed in cutting out the central portion of the said sheet metal; blank to produce the semi-annular section, and said projection being bent backwardly, overlapping the section near one end thereof. This hinge member is preferably formed with a rib 10in the bend 11' and' extends to a point near the outer edge of the plate that is of dish shape, as is clearly shown in the drawings.

' A hinge tongue 12 extends from the portion 6, this tongue, being offset, as at 13, so that its end may rest against the hinge member 9, and a rivet 1 1 or like device is employed for pivotally connecting the parts. The meeting ends of the two sections are provided with a hinge joint consisting of-a curved recess 15 upon one of the parts and a corresponding round corner 16 on the; opposite part, both curves being struck from the center of the pivot 14:, this to permit free swinging movement of the two parts.

Any means for removably securing .together the meeting ends of the section located opposite the hinge, may be employed, as herein shown, a keeper flap 17 being formed from the metal originally, composing the central part of the sheet metal blank from which the semi-annular section 6 is formed, said flap being'bent backwardly to form a recess within which a keeper tongue 18 from the section 7 may project, the two parts being secured as by means of a small lug 19 on the keeper tongue adapted to be retained by the spring pressure of the parts wi-hin a recess in a teat 20 in the flap 17, this recess preferably being formed by indenting the metal of the tongue to form the recess. The tongue 18, in the structure shown in Figs. 1 and 2, is formed of the metal originally composing the central por tion of the sheet metal blank from which the semi-annular sections are formed, this tongue being bent backwardly upon the plate in a manner similar to the construction of the flap 17.

In the form of structure illustrated in Fig. 3 .the' tongue 21 is extended directly from the end of the section 7, this tongue being of a width at" its base to fit snugly between plate. 7

While the member 12 is shown as formed from metal originally located at the end of the semi-annular sheet metal blank from which the section is formed, and the mem:

said blank, I contemplate as within the invention either or any number of these members'formed in any-of the waysshown and the upturned edges 22-23 of the bers 9, 17, and 18 from metal from within V7 I also contemplate that the overturned part may be formed from metal bent or overturned from any part of thesections.

I claim:

1. A ceiling plate including two sections of equal lengths united to form an annulus,

two of the diagonally opposite ends of the sections having members projecting beyond the edges thereof, one of said members being provided with an opening and the other with a depression, the other two diagonally opposite ends having members formed on the inner edges of the sections and folded over the same With the outer side edges lying substantially parallel with the ends of the sections and spaced inwardly thereof, one of said last named members having an opening therein adapted to register with the opening in the first named member, a pivot pin passing through said openings and a teat formed on the other one of the last named members adapted to be received in the depression in one of the first named members, whereby the sections are hinged at one end and releasably engaged at the other end.

2. A ceiling plate including two sections united to form an annulus, two of the diagonally opposite ends of the sections having members projecting beyond the edges thereof, the other two diagonally opposite ends having members formed on the inner edges of the sections and folded over the same with the outer side edges lying substantially parallel with the ends of the sections and spaced inwardly thereof, and means for hinging one set of opposed ends and detachably connecting the other set of opposed ends.
