BED.

Specification of Letters Patent.

Patented Dec. 10, 1907.

Application filed September 14. 1907. Serial No. 392.891.

To all whom it may concern: v

` Be' it known that I, JOHN J. DUNN, a citizen of they United States of America, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Beds, of which the following is such a full, clear, and exact description as will enable others skilled in the art to which it appertains to make and use the same. i

This invention relates particularly to eX- tension-bedsteads and the object of the invention is to provide a bedstead of a simple construction which can be easily and quickly varied in width without necessitating any removal of the springs. "With this object, and such other incidental objects as hereininvention consists m certain novel features which will be hereinafter first fully described and then particularly pointed out in the claims.

In the accompanying drawings, which fully illustrate my invention, Figure 1 is an end view of a bedstead embodying my improvements; Fig. 2 is a plan view of the same 5 Fig. 3 is an enlarged detail view of a ortionv of a post and the adjacent end of the bedstead, andl Fig. 4 is an enlarged detail view of a portion of the springs.

The bedstead is constructed throughout of 'metal, the side bars, 1, being formed of tubing having their ends iitted on studs, 2, projecting from the corner posts, 3, the side bars being held against dropping from the studs in any desired manner. The posts are further provided with lateral arms, 4, which may be brazed, riveted, or otherwise rigidly secured tothe posts, the studs 2 beingblikewise made rigid with the posts. The lateral arms 4 project inward from the posts and are formed with threads, 5, which are engaged by winged nuts, 6, the ends of the arms entering -the horizontal tubes, 7, forming parts of the end panels of the bedstead and the nuts bearing against the ends of said tubes. The end panels are constructed of tubes brazed or riveted together so as to provide a rigid structure and ornamental configuration.

In order to hold the posts against falling away from the end panels, I employ short chains, 8, which are passed around a vertical bar of the panel or otherwise made to engage may be given any desired the anel and are carried by springs, 9, which) are supported by rings, 10, shpped over the posts. The slats, 11, consist of metallic bars having their ends engaged and held by springs, 12, hung on rings, 13, which may be mounted on the bottom bar of the end panel but are preferably, as shown, mounted on horizontal tubes, 14, arranged below the end panels and supported on arms,

15, similar in all respects to the arms`4.

Transversely, the bars are joined by chains or other flexible connections, 16, and are held to the side bars by springs, 17, which are engaged at one end in the said chains 16 and at the opposite end in rings, 18, mounted on the side bars.

The casters, 19, have their spindles inserted in the lower ends of the posts and the knobs, 20, are iitted on the upper ends of the posts by dropping the stems of the knobs into the posts.

When the bedstead is adjusted to its narrowest form,the chains 16 are collapsed below the slats. the bedstead the nuts 6 are rotated so that by reason of the nuts bearing against the ends of the end panels the lateral arms 4 and the side 'bars will be caused to move outward, the

chains 8 having been iirst adjusted to permit the required movement of the posts and side bars and hold the posts in the position toI which the bedstead is expanded. The outward movement of the side bars puts a tension on the spring 17 which draws the chains4 16 taut and separates the slats so that they will support a wider mattress, the rings 13 moving along the end bars without any attention. i

Having thus described my invention, what I claim and desire to secure by Letters-Patent is z- 1. The combination of a post, a lateral When it is desired to widen arm projecting therefrom, an end panel supported on said arm, means for moving the panel relatively to the arm, and ieXible connections between the post and the panel for holding the post to the panel.

2. The combination of end panels, side bars, means for moving the side bars laterally'with respect to the end panels, slats, flexible connections between the slats and the end panels, and connections between the slats and the side bars.

3. The Combination of' end panels, side of tle slats, and connections between the 10 bars, means for" moving the' side bars' laten slats and the sides of the frame.
