UNITED STATES PATENT AQEEICE.
HEINRICH IIESTPI-IAL, OF BERLIN, GERMANY.
MATTRESS.
SPECIFICATION forming part of Letters Patent No. 428,791, dated May 27, 1890.
Application filed September 2, 1889. Serial No. 322,725. (No model.) Patented in Germany February 3, 1887, No.41,691.
To @ZZ whom t may concern.-
Be it known that I, HEINRICH WEsTPHAL, a subject ofthe Emperor of Germany and King of Prussia, residing at Berlin, in the Kingdom of Prussia and Empire of Germany, have invented certain new and useful Improvements ,in Mattresses, (the same having been patented in Germany on the 3d day of February, 1887, No. 41,691 of which the following is a specilicatiomreference being had therein to the accompanying drawings.
T his invention relates to spring bed-bottoms or wire mattresses; and it has for its object to provide such a mattress of wire-netting with end stretchers and with adjustable intermediate spring-supports for yieldingly carrying the weight of the occupant in the most comfortable manner; and with these objects in View my invention consists of the novel devices and combinations of devices hereinafter described and specifically claimed.
In the accompanying drawings, Figure l represents a plan view of the mattress; Fig. 2, a longitudinal vertical section of the same; and Figs. 3, 4, 5, 6, 7, and 8 are similar sections of modified devices.
Corresponding letters of reference in the several figures of the drawings designate like parts.
The wooden frame-work for this mattress consists of two rectangular frames of equal size, each composed of side rails a and end rails a', and both frames secured one on top of the other with separator-pieces d2 between their corners. Over the end rails d of the upper frame are placed wire hooks g, engaging rings C', that again by links g2 are coupled to the ends of spiral spings b, the opposite ends of which again by chains g3, composed of hooks and rings in alternate order, connect with the central sheet of wire-netting c, also composed 'of hooks and rings diagonally engaging to be iiexible in every direction, and the hooks at the side edges of this wire-netting c engage eye-screws h, secured into the side rails a of the upper frame. This net-work o thus being spread between side rails a, the tension of springs b will stretch it to be flush and level, yet when occupied by a person for night rest the center would sag down too much to be comfortable were not other elastic supports provided to assist in sustaining the mattress-sheet.
In carrying out my invention I may attach auxiliary supports for the central netting c, as shown by Figs. 7 and 8, and as described and shown in my German Patent No. 41,691, consisting of a series of spring-arms d, each rigidly secured withone end upon the lower end rails a', and upwardly curved at their inward ends and with a hook at its extreme end engaging one of the end links of the central netting c, and because, with being compressed, the end of each such spring d will describe a curve-line, the ends of opposing springs d will approach, whereby the springs b will be increased in length and the central netting c will be released of its tension, allowing it to sag down, as illustrated by Fig. 8; or I may provide angular props d', each with a hook at one end for engaging the netting c, and with a loop at its. opposite end engaging the end eye of a spiral spring f, having` to its opposite end a screw-threaded shank e, passed through a hole in a cross-rail a3 of the Jframe, and provided with a nut s for adj usting the tension of spring f, all as shown in Figs. l and 2. Thus arranged, with depressing theV mattress, not only the springs b will be expanded, but the springs f will at the same time exert their elastic force to support the central portion c of the mattress.
This device can be modiied by placing the props d to cross each other and by uniting them to eyeboltsy e', passed through holes in transverse rails a4, and by placing a spiral spring f over the end of each eyebolt e between rail a4 and nut s, when the sprin gs f will elastically resist the yielding of props d by being compressed, all as shown by Fig. 3.
In Figs. Ltand 5 I have shown another modiiication in which toggle-joints m a, pivotally connected by pin o, are coupled to hingeplates i upon transverse beams d5, while the upper end of each toggle n engages the wirenetting c. The center pins o of each two opposing toggles are coupled by hook fa to the opposite ends of 'a spiral spring p, which will be expanded for the wire-netting to yield to pressure.
Still another modification is shown by Fig. G, in which bow-shaped springs q are secured IOO upon transverse rails e* for supporting the ends of the netting r, and fr C-shaped spring lr is secured with its ends upon both rnils a" for supporting the center of the netting c.
What I claim isw l. A mattress consisting of :L frame having transverse rails on the bottom thereof', :L eentrnl netting c, springwire connections therefrom to the end rails of the frame, and supplemental spring-connections consisting of elastic props or arms mounted beneath the netting and having hooks :it one end engaging` the netting and being supported at the other end by the transverse rails, as set forth.
L. A mattress eonsistingof n frame hzwing bolt, the opposite ends of said props being coupled with said eyebolts.
In testimony whereof I affix my signature in presence of two witnesses.
