UNITED STATES PATENT IMPROVEMENT IN SPRING-BEDS.

Specification forming part of Letters Patent No. 120,865, dated November 14, 1871.

To all whom it ma/y concerni Be it known that I, JOHN M. FAENHAM, of Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Spring-Beds, of which the following is a specification, reference being had to the accompanying drawing, in which- Figure 1 is a central vertical longitudinal section. Fig. 2 is a plan view of the frame of the bed without the stretcher. Fig. 3 is a latwise View of the woven-wire mattress for use with the bed. Fig. 4 is an endwise view of such wire fabric.

The objects Vand purposes of the invention are, first, to make a bed in which the more pressure there is put on the stretcher the tighter the saine `is strained; and second, to produce a cheap and simple woven-wire stretcher for the bed.

A indicates the wooden frame of the bed; A', the head. Within the frame A are pivoted two rocking-frames, which for convenience sake I shall designate herein as No.1 and No. 2, respectively. No. l is composed of the end rail a, to the Linder side of which, at either end, are attached metal sockets al, into which iit the ends of the side rails c2, to the opposite end of each of which is attached a slotted metal socket, a3, turning on the pin i, which projects from the base-plate c', which is screwed to the inside of the side rail of the bed-frame. The shape of the slot in the socket a3 is oblong in the direction of the length of the side rail a2. The head of the pin t" is oblong in a vertical direction, so that the slot can be slipped over the head of the pin when the frame is raised up vertically, but cannot escape therefrom when the frame is allowed to drop back. Rocking-frame No. 2 has an end rail, b, sockets b1, and side rails b2, of precisely similar construe tion and connection to thosein rocking-frame No. l, but the method of its pivoting to the side rails of the bed-frame is different. On the end of each of the side rails-b2 is a metal fork, b3, resting against and turning upon one of the pins c in the rack c, which rack is screwed to the inside of the side rail of the bed-frame. A stretcher, d, of canvas, woven wire, or other proper fabric is attached at its ends tothe end rails a and b, and extends from one end rail to the other. The ends of the side rails in frame No. l must be pivoted to the side rails of the bed-frame between the center and the foot of the bed; and the ends of the side rails in frame No. 2 must be pivoted between the center and the head of the bed, so that when weight is put upon the stretcher d the end rails a and b will sink down and thus strain the structure; the more weight there is on the structure the more it is strained; which would not be the case, but the opposite, if the two rockingframes were not pivoted beyond the center of the bed, as described.

The object of having the various pins c in the rack c is that greater strain can at any time be put upon the stretcher by pivoting the frame No. 2 nearer to the center of the length of the bed.

From the side rails a2 and b2 depend bars a4 and b4, pierced with numerous holes, and running down through the racks c and c. The holes in these bars are for the insertion of pins, which 4 may be placed either above or below the racks so as to limit either the upward or the downward motions of the rocking-frames, as desired. If the pins are used tolimit the downward motion of the rockin g-frames then the leather straps f and f' can be used to limit the upward motion, there being numerous holes in the straps for this purpose, which can be caught on the pins sand s. It is designed to attach the stretcher to the end rails a and b by means of slots of metal d1, pierced with holes which catch upon the hooks d, so that the stretcher can be readily detached from the end rails when desired. It is also designed to use for a 'stretcher a woven-wire fabric, the textureand make of which are shown in Figs. 3 and 4, consisting' of alternate lengths of circular spiral coils m and oval spiral coils n, interlocked, as shown. The side rails a2 vibrate on the side of the side rail b2.

One of these rocking -frames might be dispensed with, and in place thereof the stretcher be attached to the bed-frame at that end.

I claim as my invention- 1. As parts of a bed, the rocking-frames No. 1 and No. 2, respectively fitted for pivoting to a bed-frame, substantially as described, and for the purposes set forth.

2. A woven-wire fabric, composed of alternate lengths of circular spiral coils and oval spiral coils intertwined, substantially as described.

-3. The combination of a pivoted rocking-frame, substantially like either of those described, with a bar, b4, perforated for a pin, the pin itself, and l the rack e, the whole constructed, arranged, and

operated substantially as and for the purpose the short slats of metal d1, hooking upon the set forth. hooks d2, the Whole constructed, arranged7 and 4. In combination with the parts specified in operated substantially as and for the purpose theimrnediately-preceding o1ause,the strap f and set forth.

pin s', the Whole constructed, arranged7 and op- J. M. FARNHAM. erated substantially as and for the purpose set forth. Witnesses:

5. The construction shown for attaching the WM. E. SIMONDs, stretcher to the end rails-to Wit, by means of GEORGE G. SELL. (62)
