BEDSTEAD.

Specification of Letters Patent.

Application filed August 18, 1909.

Patented July 19, 1910. Serial N 0. 513,452.

To all whom it may concern:

Be it known that I, EDWARD J. RoBIsoN, a citizen of the United States, residing at Chillicothe, in the county of Livingston and State of Missouri, have invented new and useful Improvements in Bedsteads, of which the following is a specification.

This invention relates to bedsteads and it has for its object to produce a bedstead of simple and improved construction, the mattress supporting frame of which shall be supported upon springs so that a separate bed spring may be dispensed with.

A further object of the invention is to provide a bedstead of this class in which the mattress supporting frame shall be capable of vibration in a lateral as well as in a vertical direction.

A still further object of the invention is to produce a bedstead of the class described which shall be equipped with resilient braces whereby the relatively movable parts shall be connected and reinforced.

Still further objects of the invention are to simplify and improve the construction and operation of the class of devices to which my invention refers.

Vith these and other ends in view which will readily appear as the nature of the invention is better understood the same consists in the improved construction and novel arrangement and combination of parts which will be hereinafter fully described and particularly pointed out in the claims.

In the accompanying drawings has been illustrated a simple and preferred form of the invention; it being however understood that no limitation is necessarily made to the precise structural details therein exhibited, but that changes, alterations and modifications within the scope of the invention, may be resorted to when desired.

In the drawings: Figure 1 is a perspective view illustrating a bedstead constructed in accordance with the invention. Fig. 2 is a side elevation on a large scale of one of the corner posts of the same. Fig. 3 is a vertical sectional view of one of the corner posts. Fig. 4: is a detailed side view of one of the resilient braces.

Corresponding parts in the several figures are denoted by like characters of reference.

A and B designate respectively the head and foot members of a bedstead constructed in accordance with the invention; the corner posts O of said head and foot members beof the hooks.

ing provided with clamps or sockets D for engagement with the ends of the side rails E whereby said head and foot members are connected.

Each of thecorner posts C is composed of a top piece 6 and a bottom piece 7 which are connected and spaced apart by means of a strong helical spring 8. Various constructions may be resorted to for the purpose of connecting the members 6 and 7 with the ends of the connecting spring 8 but under the construction selected for illustration the top member 6 is provided with an annular socket 9 for the reception of one or more of the topmost coils of the spring 8 which may be firmly secured in the socket 9 by fastening means such as pins 10; the lowermost coil of the spring 8 is in like manner connected with a boss 11 formed upon one end of a cylinder 12. The lower member 7 of the corner post is made tubular throughout a portion of its length for the reception of the member 12 which is adjustable in the tubular member 7 by means of a key 13 for the reception of which perforations or apertures 11 and 15 are formed in the members 7 and 12 respectively. Each corner post C, it will thus be seen, is composed of top and bottom members 6 and 7 securely connected. together and spaced apart by the spring 8; vertical adjustment of the top member 6 being readily effected by proper adjustment of the member 12 in the tubular portion of the post member 7.

For the purpose of properly reinforcing the complete structure of the bedstead, and of preventing undue lateral vibration of the upper portion thereof, the top member 6 of each corner post may be connected with the bottom member 7 of proximate portions by diagonal braces G each of which is composed of two rods 16 connected adjustably by means of a turn-buckle 17 engaging the proximate ends of the rods 16 which are provided with right and left hand threads for engagement with said turn-buckle; the free ends of the rods 16 are bent to form hooks 18 adapted for engagement with the post members 6 and 7 which are provided with lateral apertures 19 for the reception It will be readily seen that these diagonal braces which extend longitudinally as well as transversely of the bedstead Will serve to firmly connect the upper with the lower post members. One of the members 16 of each brace includes a spirally coiled spring 20 which, while sufficiently strong to avoid interference with the functions of the brace, will impart to the latter a degree of resiliency whereby the mattress supporting portion of the frame of the bedstead is :madesufliciently yielding to provide a thoroughly comfortable couch.

From the foregoing description taken in connection with the drawings hereto annexed the operationand advantages of this invention will be readily understood. The construction is simple and inexpensive and whereby a bed is provided which, without needing a spring of the customary kind will be found yielding and comfortable. An improved feature of the invention is that the mattress supporting portion of the bedstead is not'merely vertically movable upon its supporting springs, butis equally susceptible of lateral vibratory movement. This enables the improved bed to be advantageously utilized for the treatment of nervous and other disease by providing means, such as a simple mechanical motor, whereby the mattress supporting portion of the bedstead may be laterally vibrated; but the vibration may be effected manually either by the attendant or by the patient himself; or by the foot of the patient pushing against somerelatively fixed object; or in any other suitable and convenient manner. Sleep will also be readily induced by the slow and even vibratory movement which resembles that of a cradle inwhi'ch an infant is being rocked until slumber supervenes.

Having thus described the invention, what is claimed is 1. A .bedstead having cornerposts each comprising a top member and a bottom member connected and spaced apart by an interposed spring; the top member of each post being connected with the bottom members of'proximate posts by resilient braces.

'2. A'bedstead comprising head and foot members each including suitably connected corner posts, each corner post'being com posed of -a laterally vibratory top member,

a bottom member, and an intermediate spring terminally connected with said top and bottom members to permit the top member to vibrate laterally.

.3. In a bedstead, a corner post comprising a laterally vibratory top member, a bottom member, and a helical spring terminally connecting the bot-tom member with the top member to permit the latter to vibrate laterally.

t. In a bedstead, a corner post comprising a top member having an annular socket, a tubular bottom member, a helical spring having its top coil seated and secured in the annular socket of the top member, a cylindrical member connected with the bottom coil of the spring, and means for adjustably securing the cylindrical member in the tubular bottom member.

5. In a bedstead, head and foot members each including corner posts composed of top and bottom member, and intermediate springs terminally connected with said top and bottom members; and braces connecting the top member of each corner post with the bottom members of the proximate posts, each of said braces being composed of a pair of members adjustably connected by a turn-buckle, and one of said members including a spring coil.

6. In a bedstead of the character described, corner posts, each including a top member, a bottom member, and a spring connection between said top and bottom members, and resilient braces connecting the top member of eachpost with the bottom members of proximate posts, each of said braces comprising two members connected together by a turn buckle, said members being provided at their free ends with attaching means, such as hooks, and one of said members including a spring coil.

In testimony whereof Iaffix my signature in presence of two witnesses.
