HELEN A. KEAN AND WELCOME ARNOLD, OF HARTFORD, CONNECTICUT.

CONVERTIBLE BED.

Application filed July 6, 1915.

To all whom t may concern Y Be it known that we, HELEN A. KEAN and i WELCOME ARNOLD, citizens of the United States, residing at Hartford, in the county of Hartford and State of Connecticut, have invented new and useful Improvements in Convertible Beds, of which the following is a specification.

The present invention relates to improvements in furniture, and particularly to bedsteads.

In carrying out our invention it is our purpose to construct a bedstead in such a manner that the saine may be easily and quickly converted from a double bedstead to a single bedstead, from a single bedstead to a crib, and to also provide the device with a removable element which may rest upon the corner posts to arrange the device as a table. Ve also propose to construct a bedstead of telescopic sections and to provide the same with means for limiting the sliding of the sections, as well as to so connect the sections to permit of the disassemblage of the parts so that the structure may be knocked down to provide a comparatively small package which can readily be positioned in a trunk or in a similar device for transportation.

It is a still further object of our invention to produce a convertible bedstead made up of a plurality of tubular or pipe members and which shall embody the desirable features of simplicity in construction, cheapness to manufacture, durability and strength.

It is a still further object of our invention to provide our convertible bedstead with a spring and mattress, both of which being so constructed and arranged as to permit the folding of the same, so that the said elements may be readily arranged to fit the bedstead when the same is arranged in any of its various positions.

Other objects and advantages will appear as the nature of the invention is more fully understood, reference being had to the accompanying drawings in which there is illustrated a simple and satisfactory reduction of the improvement to practice.

In the said drawings:

stead converted into a crib, the telescopic upper section of the head piece being lowered,

Fig. 4: is a detail side elevation showing the arrangement of a board upon the upper ends of the corner posts to convert the crib into a table, the said table being shown in section,

Fig. 5 is a plan view of the springs,

Fig. 6 is a similar view of the mattress, and

Fig. 7 is a detail vertical longitudinal sectional view illustrating the manner in which the tubular sections are connected and the means for limiting the movement of the slidable sections, and

Fig. 8 is a View of the spring clip.

As illustrated in the drawings our improved bedstead is preferably constructed of a number of jointed as well as of a number of telescopic pipe sections, we having found, from experience, that such arrangement embodies the desired strength and durability as well as rendering the construction comparatively cheap to manufacture. Of course, however, our improvement may be formed from other elements than tubes, that is, the non-slidable parts may be solid should we find it desirable to so manufacture the device.

In the drawings, the numeral 1 designates the foot portion of our improved bedstead, 2 the head portion, 3 one of the side members or rails, and e the opposite side member or rail.

Both the head and foot include the usual corner posts 5-5, each of the said posts comprising a lower tubular section 6 which rests upon suitable rollers 7 connected thereto, The lower sections have their upper ends threaded to receive the vertical tubular portion 8 of a casting 9. The casting 9 includes a longitudinal 4tubular section 10 having interior threads which receive the threaded ends of the pipe sections comprising the sides 8 and A. rIhe castings 9 are also provided with spaced inwardly extending tubular portions 11 and 12, the member 11 being arranged at a right angle to the vertical member 8 of the casting and, of course, at a right angle to the posts 5, while the member 11 is disposed asuitable distance from the said member 12. The members 12 are provided with interior threads to receive exterior threads'provided upon the tubular members forming the end rails 13` of the bedstead. Threadedly connected with the members 8 of the castings 9 are vertically extending tubular members 1d, -providing the extensions of the corner posts, and connected to the members 14, at the foot 1 oi' the bedstead, vare T couplings 15, the outer ends of the vertical portions of the said couplings being provided with suitable cap pieces 1c', and the angular members of the' T connect the cornery posts withthe upper tubular members 17 ot the' foot l.

Similar Ts 18 are arranged upon the pipe or tube extensions 19 connected lwith the members 8 of the castings 9 at the head of the device, -the said members 18 connecting the central transverse tubular sections 20 to the posts of the head.

Projecting vertically through the .Ts 18 and arranged for slidable movement in the lower sections of the corner posts of the head, previously described, are tubular inembers 2l and one or both of the Ts 18 are provided with a set screw 22 which contacts with the said members 21 to sustain the saine in proper adjusted position upon the corner posts of the head oi' the bedstead. Connected with the upper ends or' the tubular members 21 are Ts 23, the same being provided with caps 24, and atlording` a connection for the upper transverse bar 25 of the head. The member 25 is, oi' course, con` structed of tubes and is threadedly secured tothe T 23.

Arranged upon the central connecting member 20 of the head 2 is a swinging catch 26, the same adapted to be moved to have its lipped end 27 swung over the upper member 25 of the head when the said upper portion is telescoped within the lower portion of the head as illustrated in Fig. 3 oil? the drawings.

To provide a firm support for the bedstead, we have found it desirable to arrange centrally upon the side rails 8 and l suitable coupling members 28 to which are connected downwardly extending tubular niembers- 29 which provide legs, and these legs haveconnected thereto suitable rollers 30. Also to add to the strength oi the structure, transverse tubular members 31, 3.2-32 are connected vto the central coupling 28 and to the portions 1101:' the respective castings 9ct ythe corner posts. rlhe members, 31, 32%32 are provided with removable downwardlv extending tubular sections 34, providing legs for the said transverse connecting members and these legs have arranged thereon suitable rollers 36.

Allof the transverse connecting membersl including the end rails and the sections con necting the head and foot members of the bedstead comprise each two vpipe sections, one of av less cross sectional vdiameter than the other and each slidableor telescopic with the largeisection to which it is'co-extensive,

and in the showing of the drawings the ref duced tubular and telescopic sections are provided upon the side l of the ybedstead, and thus it will be noted that when a pressure is applied upon the said side t, and the side 3 heldagainst movement, the saidvsidel el may be moved toward the side 3, and so convert the double bed illustrated in Fig. 1 to the single bedstead illustrated in Fig. 2. Y Likewise the members comprising the side rails 8 and l each comprise a reduced` section or a section which is of aless cross sectional diameterv than the second'secti'on' ofthe sides, so that ,the reducedvsection may be slid'or telescoped in the 'larger sections when the deviceis toy be conve'rted'from aV single bed (Fig. 2) toa crib, as shown in Fig. S. The larger pipe sections of the side rails are, in the showingof the drawings, arranged upon the castings 9 connected with the corner posts of the footy of the bed, but, of course,'the"same may be supported by the castings connected with the head of the bed if desired. I

In Fig. 7 we have illustrated a detail sectional view showing the manner in which the pipe sections are removably connected,

with the couplings and also the manner in which the slidable or telescopic sectionsareV prevented from being entirelyrwithdrawn trom the larger sections withwhich'they are co-extensive. ltwill be noted, by reterence to the said Fig. v7 that the telescopic tubular members of the lesser cross sectionalv diameter have their ends formed with flanges 38 and thatY the T couplings are pro-V vided'with longitudinal bores 4of twoV diame' ters, providing a shoulder 39 between the said bores which affords a stop for the slidable'section when contacted bythe annularY flange 38 thereof. It will be further noted,

by reference to the said Fig. 7 that the stopV or shoulderBQ is arranged near the end 'of the coupling to which is connected the larger pipe section, so that the smaller and slidable pipe section is afforded an ample bearing even when the same is drawn or pulled outward to the limit of its sliding moifement,A so that no `weakening of the structure isV permitted lby such an arrangement.

Should it be found that, from want oic space or other conditions or circumstances,`

the room or place in which the bedstead is arranged will not permit of the arrangement of a table therein in addition to the bedstead, or when it is found desirable to.

when our bedstead is converted into a crib, and thus the device is easily and quickly converted into a crib. Of course, in lieu of the continuous ange 41 we may connect a number of boards by suitable cleats and provide longitudinally extending members similar to the longitudinal members of the {iange 41, and by arranging a cloth over this structure a simple, cheap and desirable table is provided.

t is, of course, necessary that we provide the bedstead with a spring and with a mattress, as it would be expensive and not at all desirable that a separate spring and mattress be employed when our device is set up as a double bed, a single bed and as a crib. Therefore, as illustrated in Figs. 5 and 6 we provide a spring 42 and a mattress 43 each of which is foldable upon itself and readily applicable upon our bedstead in any of its positions or arrangements.

The springs 42 comprise four distinct sections indicated by the numerals 44, 45, 46 and 47 respectively. Each of the sections 44, 45 is substantially square and each of the sections 46, 47, substantially oblong. The sections are of an equal width, the sections 44 and 45 being centrally connected through the medium of bands or rings 48, while the sections 46 and 47 are connected respectively with the sections 44 and 45 by similar rings or bands 49. When the spring is in its flat position as illustrated in Fig. 5, the same is of a size to be arranged upon the double bedstead shown in Fig. 1, and to sustain the same in proper position we employ split resilient sleeves 50 which are passed through certain of the mesh of the springs and spread over transverse connecting members (which are in the nature of slats), indicated by the numerals 32. When the springs are to be employed upon a single bed, the sections 44 and 46 are folded over the sections 45 and 47, the hinged members or bands 48 retaining the sections in proper position or alinement, and again the clips 50 are employed, the same passing through the double mesh of the spring and again engaging the end connecting members 32. When the spring is employed upon a crib (F ig. 3) the sections 44 and 45 are first swung upon their hinges 49 over the sections 46 and 47. The sections 44 and 46 are then swung over the sections 45 and 47 when the spring is reduced in size suiiicient to he arranged upon the crib, and again the spring clips 50 are employed for retaining the springs upon the crib.

The mattress 43 also includes four distinct sections 51,52, 53 and 54, the sections 51 and 52 being substantially square agreeing in size with the sections 44 and 45 of the spring 42, while the sections 53 and 54 are substantially rectangular corresponding in size to the sections 46 and 47 of the spring. The sections 53 and 54 are entirely separated from each other, but the sections are connected with the sections 51 and 52 by a suitable tape or by the covering upon one of the faces of the mattress, and the section 51 is likewise connected with the section 52. Thus it will be noted the sections may be folded upon themselves in a manner similar to that in which the spring is folded, so that the mattress in its spread position will be arranged upon the spring of a double bed, when folded centrally and longitudinally may be arranged upon the spring in the single bed, and when folded both longitudinally and transversely, the same may be readily positioned upon the spring for the crib.

From the above description, taken in connection with the accompanying drawings, the simplicity of the device, as well as the advantages thereof will, it is thought, be perfectly apparent to those skilled in the art to which such invention appertains without further detailed description.

Having thus described the invention, what we claim is:

An extension bed Comprising telescopic side and end members and transverse telescopic members connected with the side members and disposed between the end members, and substantially T shaped couplers for all of the members, leg members connected with the couplers of the side and with the couplers of the intermediate members, all of said members, including the couplers being made up of pipe members, the coupler members between the telescopic sides and the telescopic intermediate members having each a longitudinal bore of two diameters, the larger bore being of a less length than the smaller bore and the said larger bore receiving the smaller pipe sections, and the larger bores receiving the larger pipe sections, the smaller pipe sections having their ends received in the larger pipe sections formed with annular heads which rengage with the inner surface of the said larger pipe sections and which are designed to contact with the shoulder between the larger and smaller bores of the couplers to limit the outward movement of the smaller pipe sections with respect to the larger pipe sections. f In testimony whereof we aiiix our signatures in presence of two witnesses.
