To all whom it may concern:

'h Be it known that I, HARRY B. ARNOLD, al citizen of the United States, residing'atvNew` Britain, in the county of Hartford and State of Connecticut, have invented certain new and' usefullmprovements in Extension-Bedsteads, of which the following is a specification.

'My invention relates to improvements in extension bedsteads, and the objects of my improvement are ei'iciency and convenience in use and operation as h'erelnafter more specifically pointed out in connection with .the same being illustrated in the contracted or closed position. Fig. 3 vis a broken out l1 front elevation of my bedstead in its extended form with the mattress removed. Fig. 4 is an enlarged broken out plan view of my bedstead in its extended position and the mattress removed. Fig. 5 is a broken off horizontal section of the main bed section on the line :c :z2 of Fig. 1, together with a plan View of a portion ofthe extension bed section. Fig. 6 is a vertical section of a -por- -i *tion of the main bed section on the. line y y of Fig. 1. Fig. 7 is a perspective view of the two part mattress on the same scale as in Figs. 1,2 and 3. A

My bedstead comprises a main bed section and an extension bed section arranged tol move laterally to and from the said main section, a two part mattress for the said two sections, and an opening mechanism' for operating the s ai-d'extensionbed section and that part of the mattress which vbelongs thereto.

The main bed section comprises a Inat- 'tress supporting fabric, two end frames,l two longitudinal bars 8, 9, and one longitudinal tie rod 10,' the' said rails and tie rod connecting the said two end frames. Each end frame comprises front and rear legs' 11, 12,

a fabric supporting end rail 13. preferably of angle iron and rigidly. secured by `its ends to the upper ends of the legs 11 and 12, a long brace 14, a shorterbra-ce 15, both of angle iron and a track 16 in the form of a strap or plate. The fabric supporting en d rail 13 of angle iron is disposed with its angle or corner at th'e' outer upper edge of the end frame, and its horizontal member extending inwardly from' the said angle. The angle iron legs are preferably secured to the inner face of the vertical member of the fabric supporting end rail with their angle or corner at the outer ends of the said e3, rail. The long brace 14, of angle iron, i? rvranged with its vert-ical memberon the outer side and its horizontal member at the lower edge. It is secured by its rear end to the inner side of the rear leg 12 toward the lower end'of the said leg, and with its upper l end on the inner side of the fabric supporting end rail 13 at a point near the front leg 11, so that the said 'brace' extends diagonally downward and' rearward from near the .upper front corner of the end frame. The

shorter brace 15 is disposed with its upper corner or angle inwardly and is secured by its upper end to the vertical member of the fabric supportin end rail near Vthe middle of its length while its lower end is secured to the front leg 11, a little below' the middle of its length, whereby the shorter brace eX- 'tends' obliquely downward andV forward from' the said end. rail 13, and crosses the long. brace 14. The two braces are rigidly secured to eachother by means of the rivet 17, Fig.` 1. Both end frames are alike excepting as they are made in rights and lefts.

I have usedl the same reference numerals 'to designate corresponding parts of both end frames., A

Bar receiving sockets 18 ofany ordinary construction are secured to the inner sides of the rear legs some distance below their 11p-- per ends and 4also to the innerrside of the long braces 14 near the middleof their length andI at about the same distance below the fabric supporting end rails 13. The ends of the longitudinal bars 8 'and 9 lare received in the sockets 18 of the end frames while the tie rod" 10 is secured by its ends to the rear legs of the two end frames below the 'rear sidebar 8. I

I prefer to employ a metallic fabric as the mattress supporting fabric, in which case the iron end rails 13 are drilled nea'r their inner edge to receive the hooked ends of the springs 19 on which the metallic fabric 2O is stretched in the ordinary manner of wire fabric beds. This main bed section is complete in itself and may be used alone for fa narrow beds'tead if desired. It is of a peculiaiconstruction in that it is a complete bedstead standing on four legs and without any' longitudinal bar between its front legs or at its front side. The bar 8 is between the rear legs 12 and may be called the rear side bar or outside bar, because it is at the rear of the bedstead outside of the middle. bar 9 is mounted at tte middle portion of the end frames remotely from either side of the bed section, so that it is in no sense a 4side bar.l The strain ofthe 'fabric on the end rails 13 is transmitted in part through "the rear legs to the longitudinal side bar 8,

and in part through the longbrace 14 to the longitudinal bar 9 at the middle of the end frames and with no direct strain on the front egs. A The' end rail 13, rear leg 12 and long brace 14, all rigidly secured together form a triangular frame upon which the strain of the fabric is received and transmitted to the two longitudinal bars 8 and 9, so that one tie rod 10, on the rear legs below the side bar 8 near the lower rear'corner of the said triangular `frame is sufficient to tie the said end frames to ther and prevent the lower parts of thel said end frames from spreading outwardly.

position and prevents them from cooking 1nwardly at their lower ends. These frames are very rigid and substantial and enable me to wholly eliminate the ordinary front side rail of the bedstead so as to leave all of the space beneath the metallic'fabric' and in front of the inside bar 9 available for storage. As shown, l utilize this storage space for the extension bed section. The track 16 for supporting the inner edge of this bed section is arranged obliquely under the long brace 14 and extends in the same general dilrection. Its lower end is secured to the under side of the horizontal member of the angle iron brace 14, while its upper end 1s securedto the angle iron front leg 11 on the V inner side, the saidtrack being so formed and secured as to have the body portion y which forms the track proper a suitable distance below the under side of the said long brace 14. Instead of making this track proper or track rail straight from end to end,I form a depression 21- between its ends,

preferably a little above the middle of its i v length' from' which'depression in both direc tions the trackV surface slants toward Vthe brace 14,`while the upper end of the track terminates in a short and substantially horizontal portion 24, near the front ends of the end frames.

The extension bed section com rises a mattress supporting fabric, prefere Iy -metallic, two end frames, two longitudinal.

bars 8'* and 9a and one tie rod 10 connecting The' of the said leg. As inthe main bed section, one end rail, one leg anda brace firma trian the said` two end frames. Each end frame of the extension bedsection is in the form of an acute triangle and comprises a fabric supporting end rail 13a, a leg 22 on its front side, a lon r brace 14a and track lugs 23 near the angle ormed by the end rail andbrace. The fabric supporting end rails are the same as in the main bed section, and they form the longest side of the tri-angular end frame while the front legs form the shortest Aside of' said frame. The tracklugs 23 project horizontally from the outer face of the end rails 13a near theirk rear ends and are in the form of pins as shown in Figs. 4 and 5.

The legs 22 are of angle iron and are secured by their upper ends to the front ends of the endy rails 13, but instead of being arranged at right angles thereto, they are fixed at an' acute angle and when the bed'is'ex-v tended slant inwardly attheirlower ends as shown in Fig. 1. The vlong bracre `r14a is secured. by its upper end to the end rail 138L near. the track pinat the rear end, and by its lower end to the leg `22 .near the lower end g'ular franie, but .inasmuch ias there, is 'nov legA at. one-:endsfof'fthese end frames, the shorter brace of "the main bedsection lis omitted.

Bar receiving sockets ,18 are securedto the leg 22 and long. brace 14il to receive the longitudinal bars 8a and 9 as in the main bed section. `Such bars, a tie rod 10, and metal lic fabric 20, practicallyfcomplete the extension bed section. This extension section isa little lower and a little shorter than the main bed section so'that the end frames of the eX?t tension section can slide in'and out between the end frames of the main bed section. ,The extension bed section is arranged with its' track lugs 2) in engagement with or resting upon the tracks 16 of tl'e main section, W

while its legs 22' rest upon the floor. I

The lower ends of the legs may-.be pro- A l vided with any -ordinary casters. 'Vhen the extensible bed section is pulled out the track lugs 23 rest upon the short horizontal portions 24 of the track 16 and bring the inner or rear edge of the extension bed sec-.

tion and its fabric, closely tov the level of the fabric of'the main section as shown in Fig. l. ,lf the extension bed section is pushedftoward.und into the main bed section its legsmove along the fioor and the track lugs follow the track, formed as hereedge `of the extension bed section not only inbefore described, whereby the inner or rear I moves obliquely dowmvard but immediately i drops after leaving the short horizontal por?,A tion 24 and moves farther awzrv from the long brace until the said track lugs reach the depression 21 insaid track after which the. f said inner or rear edge as 1t\ moves down-Hy wardlviuore nearly approaches the long'n,V u A130 brace so that when thelower end'of the 50 necled parts.

tra ck is reached the triangular shaped eXtension bed section is Within the triangular space beneaththe main bed section in the position shown in Fig. 2. In passing into and out of this position so much of the extension i0' extension bed'section rocks on its legs-22 sol that instead of slanting inwardly as in F ig.l

1,-these legs slant outwardly as in Fig. 2, when the sections are closed, and the mattress supporting fabric is tipped into an 1 5 oblique position.z

IVhile the extension bed sect-ion may be moved in and out toclose and open up t-he bed without any special mechanism, I preferv vto provide an opening mechanism for operati ing the extension bed section. The said opening mechanism consists of a pair of levers 26, each pivotally connected by. one end to the front leg of the respective end frames of the main bed section and preferably considere ably below the upper ends of the said legs by bolts or rivets 27, a-connecting bar 28 to l which theouter ends of both levers 26 are connected, and a pair of links 29 each pivotallyA connected by one end toa bracketA 30 30 that is secured to the front upper corner of the end frames of the extension bed section and by its other end to the middle` portion of the levers 26. The said levers 26 are each provided with an edgewise bend or curve 3l' :3.7 adjacent to that end of the links 29v that are pivotally connected to the said levers as best shown in Fig. l.

The brackets 30 extend forwardly far cndugh to permit the front upper corner of i0 the end frames of the extension bed section to pass a little inside of the front upper corners of the end frames of the main section, as shown in Fig. 2 and the said brackets extend longitudinally of the two bed sections fai' enough to permit the links 29 to be pivotally connected to the extension bed section outside'oil the levers 26.

The connecting bar 28 serves as a handle 'dby whichY to4 operate the levers 26 and con- By raising this connecting bar when the bed is opened up as shown in Fig. l and carrying it over to the rear of the main bed section as shown in Fig. 2, the levers 2G pull on the links 29 and force the extension bed section into' the position shown in the said Fig. 2. A reverse movement of the said connecting bar will carry the parts back again into the position shown in Fig. l.

The `said opening mechanism is also adapted i G0 to close and open up the mattress shown in Fig. T, and the construction of the mattress and its connecting devices is such that-this may be done when the bed is made up. The two parts 32 and of the Vmattress are 55 connected together at the middle 34 of/the complete mattress as' on a hinge. The part 32 for the main bed section is provided with means for .securing said part to the said section, said means consisting of suitable tapes' or straps 35 on its under side at two or more points, so that the said `part 82 of the matti'ess may be secured to the metallic fabric s of the said main section to hold the mattress in place' thereon.

The part of the mattress for the extension section is provided with a flap or fly which is secured by the middle portion of one edge to the under side of the mattress.

part It is so secured by the stitching 37 but in order to permitthe bed clothing to `be'tucked in under the mattress care is taken notto have this stitching extend to the ends of the mattress and also to;' "have this stitching' some distance from the edge of the mattress so as to leave both lower corners of the flap free. The Hy oi Hap 3G is wide enough to fold over the front edge of the .mattress part 3?) and to be turned down on the top of the mattress as shown in Figs. l and 2, so as to bring the free edge of the Hap on the top of the mattress nearly opposite or directly over the stitched edge on the underside. The free edge of the flap 36 is provided at each corner with a suitable fastening devicepreferably the socket memi ber 39 of an ordinary balLand socket glove fastener, while the free corners of the under edge are provided with straps'40 having one or more ball members 41 of a glove fastener thereon so that the top and bottom corners of the flap may be fastenedtogether by means of the said fastening devices, as shown in Figs. l1 and2. Several tapes, formin a Aseries of tie straps 42 are secured to the ap 36 in a row that extends longitudinally along the middle portion of the said flap for securing it to the connecting bar 28. I also prefer to connecttlie under corners of the tlap 36 to` the underside of the mattress part 33, by means of diagonal tapes or straps 43 which are secured by one end to the said corners and by their other end to the rear or inner edge of the said part at some diswrtance from thel ends as shown in 141g. 4.

VThe entire flap 3G 'is free from the mattress except where its under edge is stitched to the underside 'of the mattress. 'The only iis purpose or use for this flap which forms a pocket., isto connect the'inattress with the opening means and to inclose the front edge- `of the mattress With bed clothes thereon, in

order to ctirry ovei' the shiftable mattress and bed clothes in opening and closing the bed. When the bed is to b e occupied the pocket is opened up and its upper part turned down out of the way. ,The tapes by -which the mattress is secured to the main bed section should be remote from the edges so as to permit the bed clothing to be tucked in under .the mattress.

clothing at vthe front 5f the bed and fastened in place-bythe' fastening devices 39', 40 and 41. v With thepart 32 of the mattress fas. tened to the main bed section and the part 33- f secured bythe tapes 42 to the connecting bar 28 of the opening mechanism, the sad openf ing mechanism will turn over the part 33 f the mattress upon the part 32, changing lit 'from the position shown `in Fig. 1,'to that shownin Fig. 2, whenever the said mechanism is operated toclose the bedstead and also turn `the said part 33 of the mattress back, again into its former position whenever the bed is opened up bythe said opening mechanism. This it will do so long as the u per and lower leaves of the flap are. gecure together by the fastening devices whether the bed vis made up'or not, and if the bed is made up itwill so close and open the mattress without disarranging the bed clothing. By pivoting the levers 26 of .the opening mechanism to the middle portion of legs 11 the distance from the connectingbar` 28 to which the outer edge of the part 33 of the mattress is connected to the mattress supporting fabric, when directly overfthe pivots 27, is less than the width of the said part, and consequently only the front portion of the said part has to be lifted bythe said connecting bar to. rollover the said front part, while the rear part lies on the metallic fabric and is supported thereby. as the said part'33 is rolling over to and from the rear part 32. This makes'the partseasy to operate and avoids undue strain on the mattress or lthe fastenings bywhic'h the front part is con..

necte'd with the yopening mechanism. As the mattress thus rolls over when partly slippen-ted itis deflected into a partial coil and the pull of the pocket thereon is more or less transversely to the sides of the mattress and kto the bed clothes, so as to create friction thereon tending to prevent the bedclothes from fallingout of the pocket as they might sometimes do if the bed clothes and mattress depended. vertically from the bar of the opening mechanism.
