EXTENSION-BEDSTEAD.

' Specification of Letters Patent.

Patented Jul 14, 1908'.

Applgcation filed. March 19, 1908. Serial No. 422,036.

To (Ill whom it may concern:

Be it known that I, HARRY B. ARNOLD, a citizen of the United. States, residing at New Britain, in the county of Hartford and State.

' of Connecticut, have invented certain new and useful Improvements in Extension-Bedsteads, of which the following is a specification.

My invention relates to improvements in extension bcdstcads and the main object of my im rovement is efficiency in operation, partieiuarly with reference to ease and con venience in opening and closing the bed to change it from a couch to a bedstead and vice versa. y

In the accompanying drawing r-Figure 1 is a plan view of my bedstead when opened up for use as a bedstead; Fig. 2 is .anelevation of the same as viewed from the under side of Fig. L Fi 3- is a likeelevation of the same i when close up for use as a couch, together with broken lines showing an intermediate position ofthemoving parts. Fig. 4 is an enlarged elevation showing one corner of m extension bedstead as viewed from the le t in Fig. 1. Fig. 5 is an elevation of the right hand uppercorner, (Fig. 1,) of the bedstead or main ed section.

My bedstead is of the class in which two opposite edges of a fabric are attached to opposite fabric supporting bars between which the fabric is usually stretched. As. shown, the fabric is composed of a metallic net work 5 with springs 6, at the op osit'e edges. This is the ordinary form of t e National wire fabric for receiving and supporting a mattress upon a coucli' or bed, an any ordina mattress supporting means maybesubsti tuted for the particular fabric herein' show'n;

40 The sprin s which constitute two opposite edges of the mattress. supporting means in the main bed section A, are connected with the two fabric su porting bars 7, said bars being preferably ormed of angle iron and perforated'to receive the hooked ends 8 of the springs 6 as best shown in Fi 5. The ends of these bars 7 are connected to corner irons 9, which extend downwardly in the form of legs andehave theirlower ends con- '50 nected withanylsfiitable brace, as'for example the bars 10, which, as shown. constitute the lower side of a rectangular frame, the other sides of the said frame being formed by the fabric supporting bars and legs. To the a t e are longer or shorter,

lower ends of the legs ordinary casters 11 having swiveling frames, are attached.

Thejwo rectan ular frames each having a fabric supporting ar are connected together at the desired distance apart by means of bar supporting'rails 12, and tie braces 13 So that the fabric is stretched between the two rectangular frames. I have shown only a por tion of the fabric, but in use it will extend substantially the length of the fabric supporting bars 7, 7. These rails and tie braces may be of any desired length, the construction and o oration being presisely the same whether of i lustration, I have shown them relatively shorter than" they will ordinarily be made. The rails are set lowerndown on the corner For convenience irons or legs than the fabric supporting bars iirorder that the rails may not e in the Way of-the fabric. The two rectangular frames, the rails and braces connecting the I said frames and a fabric stretched between the said frames constitute the main bedstead or main bed section. As shown it is substantially .of an ordinary construction and of bars have corner irons 9? which a so form' legs, and to the lower ends of these le s I attach a caster 14, the wheel'or roller 0. which is mounted in a fixed or non-swiveling frame, the axis of which caster wheel is parallel to the rails 12 of the main bed section, so that the caster will always bein a position to roll toward or from the main bed section. The

.opposite ends of the fabric supporting bars 7 of the extension section have neither legs nor feet. These bars 7 are connected by a bar su porting rail 12 and a brace 13*, attache to the corner irons or legs 9 as in the main bed section. The length of the rail and brace is such that the fabric sup )orting bars are a little farther apart than in the mam section, so that the extension section may be placed on the top of the nisiii section and the respective isibriclsupporting bears oi the n ein enc extension sections be nested one within the other with the-vertical rindhorizontal members of the angle iron in the bars I overlapping the controntinguppercorners oi: the main bed section, as shown in Fig. ft ,brece may be pieced diagonally within the corner of the hers 7 and corner irons or legs. From this description it will be seen that the fabric of the extension section is attached to a frame that is in plan view substantially the forni of snnngule'r letter M. A. pair of brackets or links 16 ere rigidly connected to gether by means of e t'ubuler ber 17 and s strap form of brace or tie 18, so as to form with the said brackets e rigid frame for'nse an openln mechcnlsrn- C by ineens. of

which the main andextension. bedssections are ivotelly connected were each other.

The ower'ends of the links or-breckets-lb,

ere pivoted by a bolt or rivet 19 to the bars -10 on the outside of the main section, while their 11 per ends are pivoted by s/bolt or pin 20 to the fabric supporting bars 7 a of the ex.- tension section not for irons the legless ends of the said bars. The rigid connection consisting of the her l7 and tie is of the bracts 'ets or links 16 is between the pivotal ends of thessid' links. When so mounted the tubular'bsr17 and strep like tie 18 of t e sion section sss throiwh the two some so oporting fremes of the main section where they. may swing between the several sides of the said frames. I prefer to secure a lug 21, Fig. 4:, on the inner face of the brackets so thetthe vertical member of the angle iron of the fabric supporting hers 7 me be received between the said lug and end of the bracket and the bolt or pin pass through all three arts, as shown in Fig 4. The strain of the ebric of the extension section is in part susteined bythe said brackets. These brsclrets ere heldby their rigid connection at the proper distance sport so es to be out of frictlonal contact w th the fabric supporting frames of the mom sections-11d prevent the o 'eninfl' mechenismf om dre in or bindin on the said main section.

It desired it fine lug or projection 22 may be secured to the main bed section underneath the horizontal morn-her ofthe angle iron fabric supiortin bars of the extension bed section for t s said Inemberto rest upon. at times. i As beforestoted the bedstead is illustrated in Figs and 2, as extended. In this position, thstedge of the extension bed section which over hips the main bed section rests upon the to of the said Inein section and is supported t iereb'y, While the opposite edge is supported by the corner iron legs and casters; The opening mechanism is. now idle'only as it serves to prevent the extension section from moving outwerdly from the main section, while the msin section prevents brackets on the pivots 19 to lift the iliner' Y edge of the extension section and it the some time nioveit towsrds the main section as indicated by broken iincs in Fig. 3. As the extension. section itild opening mechanism. ere carried beyond the dead center of the opening mechanism, as thus indicated by broken lines the moving parts swing 1sternlly end downwardly into the position shown by fulllines in Fig. 3, in which, position the assesses bed section rests upon the top of the main bedstead or bed stion. prefer to'mekc the corner iron iegs S? of the extension bed section so short that when in the'position shown in.

In an extension bedstead, the combination of a main section with an extension section and an opening mechanism pivotally connected with thesaid two sections, the'sai d mechanism consisting of a pair of o -ening I P brackets rigidly connected together swingin above t en- 'pivotal connection with the said main section.

In an extension bedstead, the combination of a main bed section having two fabric I casters upon which .the said legsare supported,'. an extension section having two fabric supporting b s a connecting rail between the said bars 2i theouter ed e of the sald extension section, and a pair ,0 legs at the'ends of the said rail casters on the said legshaving rollers with;
