To all whom it may concern.'
Be it known that I, HARRY B. ARNoLD,.
a citizen of the United States, and a resident of New Britain, in the county'of' Hartford and State of Connecticut, have invented a new and Improved Bed, of which the following is a specification.
My invention relates more especially to that class of beds that may be arranged, in compact form to occupy comparatively little space, and that may be extended or unfolded when occasion requires to increase their capacity.
One form of device embodying my invention and in the construction and use of which thc objects herein set out, as well as others, may be attained, is illustrated in the accompanying drawings, in which- Figurc 1 is a view in side elevation of a bed embodying my invention with the up* per bed member partly raised, and with parts broken away. Fig. 2 is a top plan view of the same, the upper or movable bed frame, however, being removed by breaking off the uprights. Fig. 3 is a view in cross section through the bed/ron plane denoted by dotted line 3--3 of Figy2. .Fig 4 is a detail. view of the rests. Fig. 5 is a detail view showing the position of the uprights when the upper bed frame is fully raised. Fig. 6 is a detail view showing the construction of thc tracks for the carriers. Fig. 7 is a detail view showing the means for adjusting the sprocket chain.
In the accompanying drawings the numeral 8 indicates the head end and 9 the foot end of a bed of any approved t'form provided with the usual corner posts each having tangs 10 recessed to receive thetenon 12 of a side rail`11, all of which parts are of ordinary and well known construction.` A bed frame rests upon the side rails 11, this frame including in'its construction .rests 13, end rails 14, guide rails -16, and clothes guards 17. The rests 13have shoulders 18 that rest upon the side rails 11, and the guide rails 15-16 are secured to these rests in any suitable manner, as are also the end rails 14 which are nl usual construction,
`the base of the latter.
From this construction it will be formedI from angle iron and arranged to re ce1ve and sustain the spring fabric 19 of the bed. The guards 17 "pass through openings in the rests and are preferably held as by means of nuts engaglng they threaded ends lofthe rods. A folding elevating frame is located at each end of the bed frame, this including cross pieces 20 connecting the ends bf uprights 21, the latter being pivot-v ally connected at their'op'posite ends to an upper bed frame consisting ofside rails 22 andend rails 23 suitably joined` and supporting a spring fabric 24. Struts 25 are Patented Nov. 11,1913.'
pivotally connected to the uprights 21, preferably about midway of the length of the uprights,'each strut being pivotally connected to a rest at the end ofthe strut opposite that at which it is join ed to the upright, the pivotal connection with the rests-being near The rests 13 are squared at their upper ends to receive the corner pieces 26 of the upper bed part or frame, the ears 27 of said corner pieces restin outside of fingers 28 on the rests, where y the upper bed part is held securely against lateral movement when in its lowermost position. A bracket 29 is secured to each of the lower guide rails 16, and a platform 30 is supported by these brackets,j as herein shown upon bars 31 secured to the bracket. A crank shaft 32 'is mounted in the bracket and in bearings upon the platform and has a worm 33 meshing with' a worm wheel 34 on the shaft 35 of a sprocket wheel 36. A sprocket chain 37 extends site sides thereof, as clearly shown'fin Fig.-
6/of the drawings, and carriers 44 are secured to the chains, each carrier being pivotally connected by a raising and lowering bar 45 with one of the cross pieces 20.
seen that i when the upper bed frame is in its lowermost position the struct-ure may be used for every purpose required of a bed, the entire space-between the' head and footA ends be,- .ing utilized for bed purposes and enabling the use of a 'mattressv of a length substantially that of the distance between .the-head and foot ends. V g d It will be noted that by turnlng the han- ,10 dle46 and rotating the sprocket wheel 36,v
operating the l,chain 37, the carriers 44-will be moved alongtheir tracks forcing the raising and lowering bars 45 against the cross bars 20, separating the latter, and,
' '15 'through the uprights 21 and struts 25, causan extremely lgid and strong support for the upper bed section.
.While I have shown and described herein I a preferred form of construction embodying myv ideas, this may be departed from to a -greater or lesser extent and yet be Within the spirit and intent of the invention.-
` rlhe rests 13, as Well as aording a snpport for the upper vbed frame when in its lower" position, also serve as positioning means for the upright supports for said `upper bed frame, as,` when the cross bars 2O are forced apart the upright supports will be received in the grooves 47, and should one `of the supports on a single frame reach v its seat before the other, the force imparted to the cross bar 20 will cause theother support to be seated in its groove 47 ,and the upright supports are thus positioned by the rests at the corners of the frame.
As a means for adjusting the sprocket chain 37, the saddle 48 upon 'which the vsheave 39 is supported has ,a lug 49 resting against an adjusting washer 50 supported on the bolt orpin 51 that holds the bar 40 in place, said pin projecting through a slot inthe saddle@ This washeris flattened on different sides, the flattened parts being located lat different distances from the center 55 of the washer, so that by resting the lug against therdifferent sides of the washer various degrees of tension lmay be given 'to the sprocket chain.
When fthe' parts are in their lowered positions the force employed to raise the movable bed frame is exerted so nearly lengthwise of the different leve or supporting members as to require considerable force for this vpurpose unless some means for imparting livelinessi-tojthe members be employed,
and to thisl end springs 52 are secured to the .struts 2,5 and to the rests 13'as a means of assistance in the raising action, especiallylowest position, and means for actuating the uprights. A
