FRAMEWORK AND SPRING SYSTEM FOR BEDS OR OTHER ARTICLES F FURNITURE.
SPECIFICATION forming part of Letters Patent No. 791,297, dated MayBO, 1905.
Application lil-ed Marel! 8, 1904:. Serial N0. 197,144-
.l'o all whom, it 17m/y concern:
' Be itknown that T, JAMES I-I. SHERRARD, residing at Montreal, in the county of Hochelaga and Province of Quebec, Canada, have invented certain new and useful Improvements in Framework and Spring Systems for Beds or other Articles of Furniture, of which the following is afull, clear, and exact description, such as will enable others skilled in the art to I0 which it appertains to make and use the same.
This invention relates to improvements in the spring systems and supporting devices of beds and other articles offurniture.
' One of the objects therof is to provide means for bracing and strengthening the frames'of beds and other articles of furniture, whereby the peculiar tension to which they are subjected in use may be balanced .in whole or in part and the injurious effects thereof substantially eliminated.
Other objects and advantages will bel in part obvious and in part pointed out hereinafter.
The invention accordingly consists in the features of construction, combinations of elements, and arrangement of parts which will be hereinafter fully described and the scope of the application thereof pointed out in' the claims.
1n the accompanying drawings, which illustrate one ofvarious possible embodiments of the invention, Figure 1 is a plan view of abedspring frame, showing my invention as applied thereto. Fig. 2 is a transverse section 3.5 taken on line m of Fig. 1. Fig. 3' is a perspective of a brace used'as an auxiliary supporting means for the spring system.
Similar reference characters refer to similar parts throughout the several views.
The invention proposes, broadly, a frame, whether adapted to be used in a bed or for other articles of furniture, a main supporting system adapted to be carried thereby, and an auxiliary support or supports adapted to co- 4'5 operate'with the main supporting system in transferring the load to the frame and also adapted to relieve the frame of injurious Strains present in structures known in the art.
As carrying out these broad features of invention there is shown in Figs. 1 and-2 a frame 1, preferably rectangular in form and of metallic construction. Where this frame is hollow, as shown, this feature being known in the art, it is preferably stiffened and the tendency to buckling of the members thereof'reduced by inserting a ller-strip 2, preferably of wood. As embodying amain supportingsystem carried by this frame Figs. 1 and 2 kshow a spring system composed of spiral springs 3, over which upholstery or other covering may be placed. These spiral springs are supported upon longitudinal vand transverse wires 4 5, the
. ends of the wires being supported from the sides and ends ofthe frame and the springs being supported at the points where the various wires cross. As shown, the sup porting-wires are preferably bent or 'corrugated in order to provide a more convenient and eflicient means for'supporting and securing the spiral springs thereon and their central portions are dropped down or depressed below the plane of the frame. This construction, however, is known in the art and is only illustrated herein as a construction which may be efliciently used in combination with the invention here disclosed. With this spring system andother systems known in the art there is a marked tendency for the frame to become distorted and to buckle inwardly in use by reason of the fact that the greater portion of the 'weight to be sustained by the system is normally carried at points within the outline of the frame, so
that there .is a downward and inward pressure which acts to draw the various parts of the frame inwardlytoward the center. The present invention accordingly proposes an auxiliary supporting means, which shall cooperate in part with the longitudinal and transverse supporting-wires ofthe spring system for transferring theweight therefrom to the frame and which shall Ado this in such manner as to neutralize the tendency of the frame to buckle inwardly. As shown in Figs. 2 and 3, this object is attainedV by means of a brace or connecting member 6, which isy preferably of T-iron having the web uppermost and cut away at each end, as shown at 7, Fig. 3, and the remaining flange arranged to form the horizontal supporting member 8, but may be of any desired form and material. This connecting-brace is stretched across the frame at any desired point and secured in any desired manner to the frame members, and the length of the brace is determined by the horizontal distance between the inner edges of the frame members, so
that the downwardly-extending portions 9 will lit snugly against the same. It is preferably arranged transversely of the frame, as shown in Fig. 2, and attached'thereto in any suitable manner, as by screws 10. The ends of the brace preferably extend downwardly from the points of support upon the frame,and the lower extremities of these downwardly-extending portions have an arched connecting portion therebetween. All parts of the brace preferably lie substantially within the same vertical plane. The arched portion of` the brace projects upwardly into the plane of the supporting-wires of the spring system in such a manner that a portion of the weight upon the spring system is carried thereby, while the portions of the brace adjacent the downwardly-extending ends are out of contact with said wires, as shownat 11 and 12. Obviously the relation of such brace, of which any number may be provided, both to the frame members and to the spring system may be widely varied without departing from the scope of this invention as outlined. If desired, the inner faces of the frame members at the point at which they engage the braces may be especially adapted to resist the outward pressure of the same by means of a block or projection 13, of wood or other material.
The operation of this embodiment of my invention is as follows: Upon any downward pressure being applied to the spiral springs the same is transmitted to the longitudinal sustaining-wires, for the reason that these wires are preferably located beneath the transverse wires. The central longitudinal wires rest upon the brace, and thus transmitting the stress directly to the latter tend to depress the upwardly-curved portion ,and straighten out the brace or braces. This straightening strain by increasing or tending to increase the distance between the downwardly-extending portions 9 tends to force outwardly the side members of frame 1. The slight depression offcross-wires tends to shorten their horizontal length and thus draw together the side members of the frame. rlhese two tendencies are opposite in direction and by a suitable proportioning of parts can be caused to be always equal in amount. Under these circumstances it is readily seen that the total tendency to lateral distortion of the side members of the frame may be nullified.
The foregoing description is merely of one embodiment of my invention, and it is obvious that many apparently widely dill'erent embodiments of the same could be constructed and still be within the scope thereof.
Although the spring-support is shown in the drawings as a plurality of spiral springs the outer rows of which are supported directly upon the frame, the peculiar method of bracing may obviously be applied to other systems of springs--as, for example, a wovenwire bed-spring. Such a woven spring may be supported upon the brace either directly or through spiral springs or other intermediate means. Also the brace may be secured at portions 8 to the lower instead of the upper side of su rface of the frame members. lt will accordingly be seen that auxiliary supporting members such as described maybe conveniently and economically added to the construction of framework for furniture, while at the same time the life of the framework and the strength thereof will be increased thereby to a marked degree. Other advantages of such construction will be obvious without the necessity for further elaboration.
