Application filed February 25 1918; Sella n6. 219,600.
To all whom it may concern:
Be it known that I, SAMUEL REUBEN KITCHEN, of the city of Bufialo, in the State of New York, United States of America, have invented certain new and useful Improvements in Spring-Mattresses and the like, of which the following is a specification.
This invention relates to resiliently supported and flexible fabrics commonly employed in spring mattresses, spring seats and the like, and my object is to devise resilient supporting means for such fabrics which will reduce to a minimum the sagging in the middle, which is the common fault in such structures, while providing ample resiliency for comfort.
I attain my object by forming the mattress of a flexible, inelastic metal fabric and by supporting-it along two or more edges from rock arms resiliently connected to the mat tress frame and normally extending diagonally upward from the frame toward the opposite side thereof, so that weight supported on the mattress fabric tends to swing the arms down toward, or below, the horizontal, substantially as hereinafer more specifically described and as illustrated 1n the accompanying drawings in which Figure 1 is a plan view of a spring mattress constructed in accordance with my invention; D
Fig. 2 a longitudinal section of the same, partly broken away; and
Fig. 3 a front elevation showing one of the springs connected to the mattress frame and the flexible fabric of the mattress.
In the drawings like numerals of reference indicate corresponding parts in the different figures.
1 is a mattress frame made of metal angle bars the external angle of each being at the upper outer side as indicated more particularly in Figs. 2 and 3. 2 is a flexible, substantially inelastic, mattress fabric of any ordinary type. I illustrate a wire net work connected to stout side wires 3. The fabric is connected to and supported by a plurality of rock arms 4 resiliently connected to opposite sides of the mattress frame and to the mattress fabric. These rock arms normally extend diagonally upward from the frame toward the opposite side thereof as shown more particularly in Fig. 2. The result of this construction is that the mattress fabric.
is normally held stretched at a higher level thangthe mattress frame so that when the mattress is depressed by the placing of any weight thereon, the arms will swing downward as shown in dotted lines in Fig. 2 without any material increase of the distance be tween their ends, so that the depression of the mattress fabric produces a minimum of sag therein.
While any form of rock arm might be employed, I show a preferred construction in which the rock arm is formed of spring wire doubled up on itself to form the rock arm and having the ends formed with coils 5 through which passes a cross bar 6, preferably a metal tube, which is secured in the angle of the frame member by means of bolts 7. The ends 8 of the coils being held between the angle bar frame and the cross bar, the coils cannot turn, and thus they form springs tending to hold the rock arms in the upwardly inclined position shown. The rock arms, it will be noted, lie substantially flat against the underside of the horizontal legs of the angle bar frame member and then bend to extend inwardly and upwardly. The coils 5 being in tension the rock arms have their normal positions strictly defined and side sway is minimized. The ends of the rock arms are preferably formed with turned down hooks 9 adapted to engage the mattress fabric. These hooks cannot disengage as the upward swing of the rock arms is strictly limited by the frame.
For most purposes, it is sufiicient to employ these rock arms at the ends only of the mattress frame, but they may also be employed at each side as shown in Fig. 1 to assist in preventing sag at the center of the mattress fabric The number employed at the ends will necessarily depend on the width of the mattress frame and the strength of the spring material used in the arms and coils.
The invention is equally as applicable to spring seats of all kinds as to mattresses and will also prove of great value for use in the construction of stretchers for carrying the wounded or sick in connection with military or civil hospitals, as the absence of center sag in the mattress adds materially to the comfort and therefore to the well being of the patient.
What I claim as my invention is In spring mattresses and the like, the combination of a frame, opposite sides of which are formed by angle bars with their external. angles forming the outer upper edges of the sides; cross bars secured to thc ing straight and engaglng the inner surface 9f thedqwynwardly directed leg of: the angle, 7 i i normally substantially enbar; said arms angle 'ba'r to'war'd the'opposite side of the frame; and a flexible substantially inelastic mattressfabfic connected at its edges to said rock arms.
