FLOOR CONSTRUCTION.

Specification of Letters Patent. Patented June 15, 1&20.

' Application filed March '17, 1917. Serial No. 155,427.

To all whom it may concern: Be it known that 1, CHARLES \VHITNEY STEVENS, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Floor Constructions, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawing, forming a part of this specification. My invention relates to floor constructions. 1

One of the objects of my invention is to provide animproved form of sound-deadening floor construction. Further objects will appear from the detailed description to follow and from the appended claims.

In the drawings, in which an embodiment of my invention is shown- Figure 1 is a perspective view of part of a room showing my improved floor construction' Fig. 2 is a perspective View of one of the cushioning supporting brackets for the nailing strips; and I Fig. 3 is a fragmentary side elevation of part of the cushioning support.

Referring now to the drawings in detail, the floor construction shown comprises a rough flooring 10 supported by joists underneath it, a plurality of cushioning supports 11 resting on the rough floor 10, a plnrahty of nailing strips 12 resting on the cushlonlng supports 11, and a finishing floor 13 secured to and supported by the nailing strips 12.

The cushioning supports are placed about eighteen inches apart along the nailing strips, and the nailing strips themselves are about sixteen inches apart.

Each of the cushioning supports 11 comprises a sheet-meta] base portion 14 which rests on the rough flooring 10, an L-shaped sheet-metal clip 15 one leg 16 of which is secured to the base 14 by means of rivets17, and the other leg 18 of which extends upwardly alongside the side face of the nailing strip, and a bent sheet-metal clip 19 having an L-shaped portion 20 shaped to conform to the L-shaped leg 21 of the base 14, and a portion 22 extending upwardly alongside the other side face of the nailing strip 12. Both side faces of the nailing strip 12 are made to slope downwardly and outwardly, and the upwardly-extending portions 18 and 22 are shaped so as to overhang the sloping side faces of the nailing strip to hold the strip down. This tends to prevent warping of the finishing floor. A pad or cushion 23 of cattle hair, sea grass, or the like, is secured to the support 11. This pad has a horizontal portion 24 between the horizontal.

sheetmetal portion or leg 16 and the bottom face of the nailing strip, an upwardly-extending portion 24 between the upwardlyextending sheet-metal portion 18 andone of the sloping side faces of the nailing strip, and an upwardly-extending portion 25 between the upwardly-extending sheet-metal portion 22 and the other sloping side face of the nailing strip.

On account of the cushioning supports 11 thereis no connection between the finishing flooring 13 and the rough flooring 10 except through the pads 23. The bases 14 are made high enough so that the pipes 26- for the gas and electric wiring can pass beneath the nailing strips 12 without coming in contact therewith.

In constructing the flooring two of the cushioning supports 11 may be placed in position one at each end of the nailing strips, and these supports may be secured to the rough flooring and the nailing strips may be secured to the supports. The intermediate cushioning supports may then be placed in position by slipping the base portion 14 and the horizontal portion 16 ofthe L-sh'aped clip 15 underneath the nailing strip with the in position. The clip 19 may be secured in,

position by a headed fastener extending through an opening 27 in the portion 20 of the clip and through a corresponding opening in the base 14.

The sheet metal parts of the support 11 are so shaped that they may be readily formed in ms. I claim as new and desire to secure by Letters Patent:
