BUILDING CONSTRUCTION.

Specification of Letters Patent.

Patented May 12. 191- Application filed October 21. 1913. Serial No. 796.397.

To all 10. mm it 722 (13 conccrn Be it known that I, JAMES M. VERNON, a citizen of the United States, residing at Everett, in the county of Snohomish, State of Vashington, have invented a new and useful. Improvement in Building Construction, of which the following is a specification.

This invention relates to improvements in the construction of dwellings and other buildings, and consists in the novel arrangement of the respectlve parts as hereinafter described and explained, and particularly pointed out in the claims terminating this specification. I

It is a matter of great importance in the erection of buildings to so construct the partitions and floors thereof that sound will not be carried therethrough: this is particularly desirable and valuable in buildings used for apartments, and it has had the careful thought and study of some of the ablest architects and builders.

Alleged sound-proof partitions and floors have been constructed in various ways and subjected to numerous tests but their elliciency has not been proven. Different methods for preventing the tltlllSIl'llSSlOll of sound fromv one room to another have been devised and tried without success. And it would seem that the-ineflicieney of the many methods has been due, generally, to the fact that in nearly every instance where some deadener or claimed interrupter of sound hasnbeen used, there has been but one row of studding in the partitions or one set of joists between the ceiling and floor above.

In constructions of this character it is neces sary to lath directly upon both sides or edges of the partition studding, and on the lower edges of the joists to which the flooring is nailed; in such cases a firm, rigid construction is the result and is, therefore, readily vibrated by sound waves thereby forming an excellent medium for the transmission of sound.

It has been my observation that where lath are nailed upon both sides of a single row of studding or upon one edge of joists to which flooring is nailed, Whether with or without yielding material therebetween although there may be some sound deadening substance interposed, sound will be carried therethrough, and this is for the reason that they are thus made practically compact structures.

In order to overcome and remedy the defects mentioned, I have devised a plan of building construction which is believed to be effective in arresting; sound waves by confining them, practically, to their place of origin.

My invention is shown in the accompanying drawings in which- Figure 1 is a perspective view of my improved construction. Fig. 2 is a vertical cross section through the floor joists and the ceiling joists. Fig. 3 is a horizontal cross section through the partition studding.

Slimilar letters refer to similar parts throughout the several views.

In the present invention, when setting up the partitions in a building, I first cure to the floor in the custon'lary manner a strip, 1. of the width necessary to support the studding to be secured thereto. Two rows of studding, Q, 3. are set in lines parallcl to each other but in staggered relation, that is, alternately more or less to one side 'of a line drawn longitudinally through the center of strip 1. For example: if 9 x 4. studding. are to be set in staggered relation as described, the strip 1 should. be about six inches wide so that the outer faces or edges of one row of studding will register with one edge of said strip and the outer faces or edges of the other row of studding will register with the other edge of said strip as shown. Between these two parallel rows I secure to the inner faces of the studding from flooring to ceiling, a lining, 15, of asbestos sheathing or asbestos paper, dead ening felt, or like material, thereby forming separated and non-communicating airchambers 6 and 6. By this construction the lath and plaster, 4', for one room are carried on the outer face of the row of studding, 2, and the lath and plaster, 5, for the adjoining room are carried on the outer face of the row of studding, 3, and between these two plastered walls are non-communicating air-chambers 6 and 6* which prevent the sound waves of one room penetrating the other room.

In the construction of floors and ceilin s a plate 7 is placed on top of the studding to carry the floor joists 8, and just beneath the plate a false girt or ribbon 9, is nailed to the studding to carry the ceiling joists 10. Between each floor joist 8 and plate 7 on which it rests, is placed a piece of asbestos, 11, or other like yielding material. The

purpose of this is to avoid direct contact of the joists with the plate and thereby interrupt the vibrations of the floor timbers caused by romping, stamping, jumping, and the like on the floor, so that they will not be con'n'nunicated to the room underneath.

The ceiling joists 10 and the floor joists 8 are placed in separated rows in staggered relation to each other as shown, and between said rows I secure to the inner faces of the joists, and the entire length thereof, a lining 16 of asbestos sheathing or asbestos paper, deadening felt, or like material, thereby forming separated and non-communicating air-chambers 14: and 14; so that when the flooring 12 is secured to joists 8 and the ceiling 13 is affixed to joists 10 the intervening air-chambers completely isolate the rooms from each other. And this form of isolation of the rooms necessarily confines to the respective rooms all noises originating therein. Such construction also results in the following advantages: The air in each room is more easily maintained at a uniform temperature; the rooms are cooler in summer and warmer in winter. And the use of asbestos lining minimizes the danger of communication of tire fronrone room to another for all drafts of air are avoided.

The separated and independent ceiling joists constructed in the manner shown and described, protect the ceiling from injury from above by reason of all jars and shocks on the floor above being intercepted by the intervening lining 16 between the floor joists and the ceiling joists and by the yielding material between the floor joists and the plate. As this form of construction of floors and ceilings is substantially that shown and described in connection with partitions, all that is hereinbefore said as to the advantages of such partitions applies with equal truth and force to the floor and ceiling as herein set forth.

The phrase parallel partition members as hereinafter used shall be construed in its broad sense as applicable to floor and ceiling members as well as to walls in the usual signification of that word.

What I claim as my invention, is-- 1. In building construction, partitions consisting of independent parallel rows of studding placed in staggered relation, the inner edges thereof being spaced substantially apart from opposite Walls, walls on the outer sides of the studding, and a pliant lining secured to the inner faces of the studding from floor to ceiling to form separated parallel rows of non-communicating, overlapping air chambers, whereby sound waves are prevented from passing from wall to wall.

2. A sound-deadening building construction comprising parallel partition members having sound-deadening chambers disposed in overlapping relation, the partition members forming the outer walls of the afore- I said chambers, joist or studding members arranged in staggered relation with their inner edges spaced substantially apart from opposite walls of the partition mem bers forming the side walls of the aforesaid chambers; and a separating sheet of pliant sound-deadening material undulatingly disposed over the inner edges of successive joist or studding members and forming the inner walls of the aforesaid overlapping chambers.
