Be it known that I, LEWIS It. BRADBURY, of the city of Charlestown, county of Middlesex, and State of Massachusetts, have invented anew and useful Improvement in Spring-Beds; and I do hereby declare that the following isla full, clear, and exact description ofthe same, reterence being had to the accompanying drawing, in whieh- Figure 1 represents a. top view, and
Figure 2 a section through :1: fr, lig. 1.
My invention relates to that class of spring-beds in which the spring is placed at each end of the bed, and is designed tp overcome many of the difficulties hitherto experienced, and common to the beds made in' this way; the o bjeet being to produce a spring which shall be easily and cheaply made, durable, not easily broken, and which shall bear handling without injury.
In the drawing, A represents the frame of the bed; BB being the end rails, into which the ends of the spring C are fastened, by being driven into the rail, and secured by a staple, the other end oi the spring, upon which the slats D rest, being held in place by the cleat E. Under the spring C,`and resting on the rail B, I place an additional spring, 1I, so that, when the spring C is depressed, instead of resting on the rail, the pressure is received by this spring, and the durability of the spring C is increased. This spring II may be a.
strip ot vulcanized rubber, or a slat, having spiral spring at eaclrend. In the drawing it is shown as made ot" rubber, and I consider this the inost desirable mode of making it.
The springt] is a. compound or double-acting spring, having a double spiral, F, in the centre of its length, which gives it the necessary iexibility. Y V
The spiral spring Gr may be used, if required, in the position shown, to give the slats greater' strength, and to keep them from bending under the weight of the bed. e
Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-
The combination ofthe spring C, made substantially as shown, with the spring H, placed under it, the two springs operating together, for the purpose substantially as set forth.
. L. Il. BRADBURY.
