. CEILING HANGER.

Application led July 29, 1925. Serial No. 46,789.

To all whom it may concern:

Be it known that I, PHILIP DUPHINEY, a citizen ofthe United States, and a resident of Waterbury, county of New Haven, and State of Connecticut, have invented certain new and useful Improvements in Ceiling 'Hangers, of which the following 1s a specification.

This invention relates to ceiling hangers, and more particularly to hangers adapted to he suspended from the joists un'der a floor for holding an expanded metal lath which formsV the support for the plaster ceiling of the room beneath.

One object of this invention is to provide a hanger of the above nature in which the so-called cross-furring strips, formerly construction in which the metal lath is con-l nected by wires to a plurality of Channel irons which are suspended from the Hoor joists by a plurality of resilient metal hangers.

A further Objectis to provide a device of the above nature which will be simple in construction, inexpensive to` manufacture, 'easy to install, and very efcient and durable in use.

With these and other objects in' view, there have been illustrated on the accompanying drawings, two forms in which the invention may be conveniently embodied in practice.

Fig. 1 represents a side view of the first form of ceiling hanger, which is madefrom bent metal wire.

Fig. 2 is an end view of the same.

Fig. 3 is a perspective view of a modified form of ceiling hanger, said hanger being nlide of bent strip metal and being adjusta e.

Fig. 4 is a transverse sectional view showing part of a floor and ceilingaconstruction in which hangers embodying both forms of the invention have been lnstalled.

Fi 5 is a longitudinal sectional view of the oor and ceiling construction showing a side view of two of the strip metal hangers.

Fig. 6 is a plan view of a portion of the expandedmetal lath for supporting the plaster of the ceiling.

In the construction of-plaster ceilings in wooden frame buildings, it has been vcustomary for some time to support the plaster upon a sheet of open expanded metal lath, said sheet having been previously stapled to a series ofv cross-furring strips which in turn were nailed to the joists of the ioor above. This type of construction yhas been found somewhat unsatisfactory in use 'because of the fact that shocks and vibrations on the floor above were directly transmitted though the joists and cross-furring strips to the plaster of the ceiling beneath. Strains were thus set up in the plasteroften causing it to crack, swell, become grooved, or even to split ofi' from the metal lath.

By means of the present invention, thel above and other disadvantages havebeen avoided. This has been accomplished by wiring the metal lath to a series of channel irons which are themselves suspended in a plurality of shock-absorbing resilient hangers, rigidly connected at their top portions to the joists of the floor above.

`Referring'now to the drawings in which like reference numerals 'denote corresponding parts throughout the several views, the first form of hanger is disclosed in Figs. l and 2, and comprises a piece of stii' metal wire bent toform an upper loop 10, which is adapted to bey hung upon a nail or screw driven into the floor joist 11. Below the loop 10, the hanger consists of a straight portion 12 which is connected to an intermediate...-U-shaped 'portion v13l having a curved'en'd 14. The lower leg. 15 of the U- shaped portion 13 is shorter than the upper leg 16, whereby thebottom part 17 of the hanger will be offset from the upper portion 12. By means of this construction, it will bel seen that there will be no danger of the lower part 17 of the hanger coming into contact with the Hoor joist 11 from which `'the hanger is suspended. z

The base 18 of he hanger is bent atI right angles to the lower part 17 thereof, and is adapted to form a seat for a channel iron 19 adapted to`be connected, as by suitable wires 2l, to a sheet of met-al' ceiling lath 20. A wire ring 22a is adapted to surround the leo' 16 of the U-shaped looplegs 15 and' 16 of the loop 13, whereby the weight of the ceiling beneath will be supported.

In order to prevent sudden shocks and vibrations on the floor above` from being transmitted to the ceiling beneath, the upper leg 16 of the U-shaped loopv 13 oit' the hanger is reduced in thickness at for a portion of its length, whereby said upper legy 1G will have a greater resiliency than the lower leg 14 thereof. It has been found in practice that when the present improved form of ceiling construction is installed, heavy weights may be moved freely about on the floor above without injury to the ceiling beneath. This result is due to the shock-absorbing'action of the reducedportion the upper rIn use, the hangers will preferablyA be spaced apart in alinement alongthe joists 11 at any desired intervals, according to the weight -of the ceiling to be supported.

It will be understood that the hangers may be attached to all of the flooring joists or only on alternate joists, as conditions may require.

The adjustable second form of ceiling hanger is shown i-n Figs. 3 and 5, and at the right of Fig. 4. This form of'hanger is constructed from a strip of sheet metal and comprises a Hat upper section 23 having

apertures

24 and 25, by means of which' the hanger may bey suspended from a floor joist 26, as by screws 24a and 25.11. The lower portion27 of this form of hanger is parallel to and offset from the upper portion 23 so that said lower portion will hang entirely free and spaced from the joist 26. The base 28 of the adjustable hanger is bent in a horizontal plane at right angles to the lower portion 27 and forms a seat for a channel iron 19 passing through a rectangular aperture 29 in the member 2T immediately above the base 28.

In order to permit the second form of hangers to be adjusted so that all of them will hold the channel ironwith an equal pressure, each of said hangers is' provided with anlintermediate loop section 30. The section 30 is preferably made of a rectangular U- shape and has its upper and lower legs 31 and 32 apertured near their bases to receive an adjusting screw bolt The head 34 of the bolt 33 is located under the lower leg 32, while the other end of said bolt extends through the upper leg 31 and is provided with a nut 35. By turning the nut 35 on the bolt 33, the base 28 may be raised or lowered to any desired adjusted position. j

In order to cause the upper leg 31 0f the U-shaped loop to absorb shocks and vibrations from the floor above, the upper leg 3l is provided with a section 36 of reduced Width, whereby said upper leg31 is made more resilient than the lower leg 32.

As clearly shown in Figs. 4 and 5, a substantial space is left between the bottoms of the joists ll and 26 and the tops of the channel irons 19, thus preventing any possible contact between said parts, which might transmit injurious vib ations from the floor above to the ceiling beneath.

One advantage of the present invention lies in the fact that the lower legs of the U-shaped loops are made stronger and stiller than the upper legs thereof, so as to resist any sudden shocks from belowwhich might occur during the operation of embedding the plaster of the ceiling on the metal lath. A further advantage of the present invention is that the ceiling plaster is in contact with all metal parts, which cannot possibly absorb it during the setting process and cause streaks in the ceiling, as was'the case with the former ceiling construction en'lploying wooden cross-furring"' strips.

lVhile there have been disclosed in this specification two forms in which the inveniion may be embodied, it is to be understood that these forms are shown for the purpose ofv illustration only, and that the invention is not to be limited to the specific disclosures, but may be modified and embodied in various other forms without departing from its spirit. In short, the invention includes all the modiications and embodiments coming within the scope of the following claims.
