CARI. InMELANDEIt, or MINNEAPOLIS, MINNESOTA.

EXTENSIBLE BEDS'IEAD'.

To all whom it may concern: 4Be it known that I, CARL F. a citizen of the United States, Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Extensible Bedsteads; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as vwill enable othersskilled in the art to which it appertains to make and use the same. f A

My invention has for its object to provide an extensible bedstead of strong, durable and simple construction.

To the above` ends, the invention consists of the novel devices and combinations of devices hereinafter described and defined in the claims.l

In .the accompanying drawings which illustrate the invention, like characters indicate like parts throughout the several views. I

Referring to the drawings, Figure 1 is a plan view showing the improved bedstead; Fig. 2 is a side elevation of the improved l MELANDER, reslding at bedstead; Fig. 3 is a transverse section taken approximately on the line m3 w3 of Fig. 2; Fig. 4 is a detail in section taken approximately on the line 004 m4 of Fig. 2, some parts being broken away; Fig. 5 is a horizontal section taken on the line x5 15 of Fig. 4, some parts being indicated by dotted lines only; and Fig. 6 is a detail in section taken on the line :1:6 ze of Fig. 2.

The head of the bedstead is made up of a pair of corner posts, 1, shown as rigidly connected by a tie bar 2. The foot member of the bedstead is shown as made up of a pair of corner'posts 3v connected by a tie bar 4. These foot and head members may, however, be of any suitable or desired design. The head and foot corner posts 1 and 3 are provided with frame-supporting devices, as shown, made up of collars 5 cast around the said corner posts and provided with projecting rest lugs 6 having transverse grooves 7.

In this improved bedstead, the spring and its frame are each made up of two parts, which constitute sections adapted to be used one in respect to the other. The head frame section is shown as made up of a pair of parallel angle iron rails 8 connected, at their front ends, by a transverse angle bar 9. The depending flange of this transverse angle bar 9 rests loosely 'in the notch 7 of the rest lugs 6 of the head corner posts l.' The foot Specification of LettersPatent.

section of the spring frame is made up of foot spring section 14 likewise is preferably clamped tothe rails 10 by metallic strips 15 riveted thereto.

Approximately U-shaped metallic 'keepers i or guides 16 are rigidly secured to the foot ends of the dependin flanges of the rails 8 and loosely embrace'4 the depending flanges of. the rails 10. Similar but reversely ap# plied metallic keepers or guides 17 are riging flanges of the rails 10 and loosely embrace the depending flanges of the rails 8. The ,keepers -17 are rigidly secured to the ends of la transverse intermediate tie bar 18, shown as of 'angle iron construction. At their upper ends, legs 19 are pivotally connected by bolts or rivets 20 to the depending flange of the end portion of the tie bar 18. By reference to Fig. 3, it will be seen that these legs 19 are adapted to be turned upward into inoperative positions, indicated by dotted lines in Fig. 3, and are adapted to be turned downward into operative positions, in which positions further outward movement of said legs is prevented by the engagement of eccentric portions or shoulders 2l of said legs with the bottoms of the keepers 17.

The connections above described make the body or framework of the bedstead longitudinally adjustable. This adjustment is highly desirable in various places where the rooms are small and space is an important item. The bed to the length of the person o r persons using the same, and ymay be left standing in such adjustment, or it may be lengthene'd out at night and very materially shortened in the day time. A slight lateral adjustment, sutilcient to-take up for the stretching of the springs, is also quite desirable, and this adjustment, as shown, is made possible by dividing the head bar 9, the foot bar 11 and the intermediate transverse tie bar 18 and adjustably connecting the sections thereof. In Fig. 3, one section of the intermediate bar 18 is shown idly secured to the head ends ofthe depend-A may be adjusted according the slack and compensate v as riveted to a short angle iron section v22, and the other section of said bar 18 is adjustably connected to said bar 22 by a slot and bolt connection 23. The same means of adjustment may be applied to said bars 9 and 11.

What I claim is: A v

l. A bedstead having a spring frame made up of a pair of sections with theirside bars constructed of angle iron, the side bars of one section adapted to slide directly upon the side bars of the other section, reversely projecting keepers for locking the side bars of one section within the side bars of the other of said sections, an intermediate tie bar connecting the inner ends of the side bar of one of said frame sections, and legs ivotally connected to said intermediate tie ar, substantially as described.

2. In a bedstead, the combination with head and foot posts, ot a spring frame supported by said posts and made up of frame 'sections adapted to slide one upon the other,

the side rails of said frame sections, at their ends, having reversely projecting keepers that embrace the side rails of the other section, an angle iron tie bar connecting the keepers of one of said frame sections, and legs pivoted to the depending langes of said tie bar and having eccentric stop shoulders engageable with the connected keepers to limit the outward and downward movements of said legs, substantially as described.

In testimony whereof I a'ix my signature in presence of two witnesses.

CARL F. MELANDER.
