FIREPROOF FIXTURE.

Specification of Letters Patent.

Patented March 27, 1906.

Application filed March 31. 1905. Serial Noi 253,051.

.To a/Zi whom, t nmy concern,.-

Bc it known that l, EUGENE l". Frrzrii'r- RICK, n citizen of the United States, and a resident of the city of Non' York, borough of Brooklyn, in tho county nl Kings and State of New York, have invented a new and linproved Fireproof Fixture, ol which the lollowing is a full, clem', and exact description.

My invention relates to lireproof fixturessnch as partitions, blinds, doors, walls, and the lil e--111y more particular purpose being to provide an inclosed hir-space, sometimes designe-ted as a vac-noni, which acts as s. non-conductor of lient.

Incidental to this purpose my invention further consists in certain constructionai details and combinations ci' parts hereinaterl described, and pointed out in the appended claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters ci reference indicate corresponding parts in ail the ligures.

Figure i is zi frsginentery iront elevation showing a partition equipped with iny invention. Fig. 2 is a horizontal section showing the manner of securing and spacing the front and back walls. Fig. 3 is o. horizontal section through a pair of shutters equipped with my invention, and Fig. 4 is a vertical section through one of the shutters.

A number of separate plates 5 5a 6 6 of lsheet metal, preferably ironJ are connected together by means of Z-bars 7 of the form shown. The plates 5 5 are in alinement with each other, as indicated in Fig. 2, and are connected together by angle-strips 8, each provided with an air-space S and heid against the adjacent plates by meansof bolts 9, provid ed with nuts 10. Between the pairs of plates 5a oa are spaces 11 11, filled with air, which serves as a non-conductor of heet. Angle-irons 12 13 ere secured upon opposite sides of the plates 5a 6'* end are used for connecting these plates with other plates 5b 6b, so as to form angles, as indicated at the right of Fig. 2. Bolts 14 are employed for the purpose of connecting the angle-plates toether adjacent to the edges of the plates 5 6a 515 6b. The angle-plates are separated by air-spaces 12a. scribed every part which would otherwise be liable to transmit the heat in case of s. re is in the construction just de:A

prevented from so doing by virtue of one or more air-spaces. Even the joints are as far es possible provided with air-spaces.

it will be noted that as the plates 5 5a 6 6 iney be :nado of dilerent widths and of different heights the partition indicated in F ig. 2 may be lengthened, shortened, widened, or narrowed at will. It will also be noted that each Z-bar 7 serves as e post and also as a fastening for the bolts 9 as weil as acting in the capacity of a subpartition separating ad- `ioining air-spaces, such as 11 lig. No boltholes are necessary, for the reason that the plates 5 5l and the plates 6 6a do not abut each other edgewse, but are disposed in juxtaposition upon opposite sides of the bolts 9 and are separated by a space representing the thicknessof such a bolt. It is this specie or crack (indicated in Fig. 1 at 9*) which is covered by the strip 8.

In Fig. 3 a pair of shutters are shown. The walls of the building are shown at 15 16 and the front and back plates of the shutter are shown at 17 18. These plates are paired, as shown, andconnected by Z-bars 19 20, held in position by "ineens of bolts 21. Hinge members 22 are rnoii'nted upon hinge-bestrings 23 andsecured to the front piate i7 by ineens of bolts 24. A`il`ange 25 is secured by bolts Z6 upon one of the front plates 17, and Similarly a iienge 27 is secured by bolts 2S upon one of the back plates 18, as will be nderstood from Fig. 3. The top of each shutter, es shown in Fig. 4, is closed by a Z-bar 29, the upper portion of which is riveted to the up er edge 17 of the front plate, the beck plate 18 being'riveted upon the lower portion of the ,Z-barii.V ;Eac i shutter contains an air-s ace 30.

Shuttersyinade as above described are comparatively light, each consisting of a composite hollow shell provided with en airspace, end owing to the shape of the Z-bars 19 20 each shutter fits snngiy around the corner of the wall 15 16, ipon which it is free to swing, as indicated in ig. 3.

1t is impracticabe to describe all of the various forms in which my invention may be used. Suffice it to say that I do not limit rnyselt` to the construction above described, and many forms differing slightly therefrom may be employed without departing from the spirit of my invention.

Having now described my invention, I

roo

claim as new and desire to secure by Letters Patent- 1. A shutter, comprising a front plate and a back late, Z-bars mounted upon opposite sides opsaid shutter, fastening members for detaehably securing said Z-bars to said front and said back platesJ and means for mounting said shutter.

2. In a shutter, the combination of a front plate and a back plate, Z-bars disposed oppositely to each other and intermediate of said plates, one of said Z-bars having the angular conformity of a wall, and a hinge member connected with one of said plates and with said wall for enabling said shutter to swing as a door.

3. In a shutter, the combination of a front plate and a back plate, members disposed upon opposite edges of said shutter and spac ing said plates apart, and a Z-bar mounted within the top ed e of said shutter and secured to one of sai( plates, said Z-bar havin a portieri for partially overlapping a wal above said door.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

EUGENE F. FITZPATRICK.
