DWELLING-IHOUSE.

Specification of Letters Patent.

Patented June 4, 1918.

. Application filed March 21, 1918. Serial No. 223,834.

To all whom it may concern:

Be it known that I, EDWIN S. DODGE, a citizen of the United States, and resident of Boston, in the county of Suffolk and State of Massachusetts, have invented new and useful Improvements in Dwelling-Houses, of which the following is a specification.

This invention relates to dwelling houses, and more particularly to a new genus of inexpensive tenement or multiple-family houses, which shall be adapted to be built rapidly and economically. It has for its principal objects to provide an economical distribution of structural elements makin for permanence, strength and security 0 the houses comparable with cost or quality of the building materials, without preventing purely architectural treatment of their exterior elevations, or in relation to the interior arrangement of separate living quarters provided under one inclosure of sidewalls and roof.

So far as I am aware it has heretofore been the common practice of architects and builders to rely for the support of loads carried upon the floors and roof of dwelling houses mainly upon piers in or constituted by the exterior walls of the house, with certain exceptions, as in metal-frame buildings, or masonry city constructions, in which houses on narrow, thin lots are built in rows so that the support for the flooring and roofing members predominantly rests upon the fire-stop or party wall usually built on the party line between lots. But in this case reliance for lateral stability has been upon the front and rear walls'of the structures. In the article of manufacture now to be described, a detached unit having light and air'on all sides and having inherent stability against lateral forces, such'as wind and earthquake pressures, is provided. It is characteristic of the new type of building that the lateral stability is wholly or in the main independent of the exterior or ourtain walls inclosing the structure, and that by such provision the exterior or curtain walls are permitted to be of a cheapened construction not heretofore possible (because not adapted to bear crushing strains or lateral stresses of the degree heretofore imposed upon them) to the end that addi-.

tional care and-expense in constructing the exterior walls may be devoted to then heatinsulating properties or to their architectural appearance instead of to their more strength, and still result in a building less expensive for the same class of construction than common practicenow provides.

Referring now to the accompanying drawlngs which show one instance only of many architectural arrangements containing the new characteristics of construction hereinafter more particularly pointed out,

F igure 1 is a plan in horizontal section above the ground floor; Flg. 2 is a similar plan in horizontal section above the second floor; I

Fig. 3 is a similar plan in horizontal sect1on above the third floor;

Fig. 4 is a typical section on line 44 of Figs. 1, 2, and 3;

Fig. 5 illustrates a modification. In the typical building shown the purpose isto accommodate four families and to provide for their insulation from each other with respect to sound, fire, smells, etc., by the complete division of the house in which the four familiesfare housed into separate parts. Whatever the architectural design of the construction, therefore, a characteristic feature of the building is a cruciform pier and partition wall A, A, preferably of heavy masonry construction and having a foundation as at A (Fig. 4) on the longitudinal and lateral bisectors of the plot covered by the building. These walls may be of brick, of poured cement concrete, of hollow tile, or of reinforced plastic construction, such as concrete reinforced with metal inclusions, or wood and mortar constructions in which the tensile element comprises planking or other timbering embedded in the plastic, or framework, or of other usual strong and rigid structure. Under these circumstances no other lateral support of the walls A, A than their juncture with each other is required and these walls alone are a pier of great lateral rigidity adapted to withstand strains in any direction, and adapted to support at their tops a large vertical crushing strain.

Conveniently, but not essentially, one of the walls as A, provides as an integral art of its' structure chimne s 4, 5, 6, an 7, which may be divided into as many flues as requisite, each to serve the habitation lying in the angle of the walls A, A. As so provided these chimney piers are additional elements of strength m a direction lateral of the walls in which they occur, and in the referred form illustrated they may thereore'be provided in the longer wall representing the greater turning moment under lateral stress upon the structure as a whole.

As illustrated in Fig. 4, the walls A, A

are carried upward to the architectural conrigidity of the system, 10, 11, A, for support. As shown the beams 12 and 13 are supported by a tension connection respectivelywith the chord 10 and with each other, and by the compression members con' stituted by the joists 14 and 16 respectively of the attic floor F and under the third floor F of the house. The roof and third floor are thus independently balanced on the internal cruciform pier, without necessary substantial aid for support from the vertical rigidity of the curtain or,exter1or walls. I

The tension connections between the beams 10, 12 and 13 may be of any known or desired type. The seats of the joists 14, 16, of the floor levels F and F with res ect to the wall A may be recesses in the wa A of any desired type adapted' to. receive. the thrusts of the respective joists 14-, and 16 and thereby to sustain the weights loaded upon the upper surfaces of the floors F and F. By the expedient mentioned it will be ob served that the support with respect to the wall A of the floors F and F is independent of any penetration of each wall A by a continuous beam constituting a stiffening member passing through the wall A for the floor F or the floor F, but I am aware that many' advantages of the prescribed construction may be procured by a continuous length of joist for either of these floors at the line 14 14 or the line 16-16, and I do not regard the invention as limited to either form of this construction.

Having explained the support of the roof construction with reference to the wall A, it will not be necessary to explain the manner in which the roof may by any usual expedient also comprise a lateral truss or trusses like those of Fig. 4:, for supporting the roof with respect to the wall A, the respective members like those shown in Fig. 4 lying at right angles to the plane of said figure and preferably being employed when the contour of the roof in elevation at right angles to the wall A is other than rectangu-- lar, and in other cases if desired.

If desired the floors F and F at their outer ends maybe supported by a tension member, not shown, in the exterior inclosing or curtain walls C or C but iiimhe preferred construction the greater part of the strain, that is to say, the support of the roof and the reaction against lateral stresses of wind, etc., having been taken from the curtain walls C and C there is no objection to calling upon these walls to take the com-- pression strain of su porting the first floor F and the second oor F at their outer ends, and these walls may therefore comprise vertical studding or masonary .piers of any usual or desired sort adapted to support the outer ends of the joists 17, 17 ,18, 18, in turn respectively supporting these floors.

In order to provide additional support adapted to prevent settling of the curtain walls themselves, they may each be provided with the usual footing 0 below the frost line asis common in house construction.

Because of the marked lessening of the stresses uplon the walls, both the construction of the wa s C and C and of the footings C, C maybe lighter than usual, or of inferior material, without detriment.

The end walls of the house 0 and'C" may be in all respects like in construction to the walls C and C.

In some cases, particularly where the attic floor F is not penetrated by a stairway or other opening for access to the attic space F and referring now to Fig. 5, most of the desired ends-can be obtained by a construction by which the cruciform separation and pier walls A and A stop at the level F of the attic floor. In this case the roof trusses B and B may be of any desiredform constltutlng a built-up girder, for instance such as shown in Fig. 5, the structure as before being balanced upon and carried by the wall A in one dimension, and if desired also balanced upon and supported by the wall A in the other dimension, as explained above.

The exterior elevations and the specific interior arrangements of the houses are immaterial to the invention, but it may nevertheless be explained that a house of such formis peculiarly adapted to the needs of a working population. Referring to Figs. 1, 2, and 3, each part may contain an entrance hall 20, closets 21, 21, and vliving-roomkltchen 22, on the ground floor; the kitchen bemg on the lower floor afi'ords advantages and economies in heating the entire section. A stairway 23 may lead to an upper hall 24; living or bed-room 25, and bath 26 on the second floor; and on the third floor, (Fig. 3), two bedrooms 27, 28, andcloset space 29 messes ,What
