HARRY D. BARTLTT, 0F DELAVAN, WISCONSIN, ASSIGNOR TO JULIUS KRAMER, 0F
` v CHICAGO, ILLINOIS. f
Sora-BED.
'To' all whom t mog/concern: y-Be it known that I, Hanny D. Banfipn'r'r, a citizen of the United States, residing at 'Delavan, in the county of Nalworth and State of Wisconsin, have invented new and' useful Improvements in Sofadeds, of which thefollowing is a specification.-
v This invention relates to improvements 1n sofa-beds, or, as they are commonly termed, davenport beds, and to that particular Aclass wherein are included a niattress-supl port composed of a series of articulated sections adapted to be opened into bedforni and be folded conveniently and conipactly'within `the base of the sofa-bed frame below the seat,- and a sofa-seat adapted to be supported above the mattress-support when folded and stored and to be overturned or invertedv and located in front of the sofa-bed frame when the n1attress-support is unfolded and -disposed in bed-form.
The principal objects of the present invention are to provide a new and improved mechanism for operating to open'and close the. mattress-support automatically as the seat is raised and inverted or returned to its original position, as the lcase may be,lto rigidly supportV said seat .by means of the lmattress#support and its` operating mechanism when the support. is folded 'within the base of the sofa-bed frame, to provide a back designed tobecome positioned in close relation with the rear edge of the seat so as to y eliminate the usually present unsightly space between these two elements,'and a mechanism for automatically elevating said back when the seat is moved to its initial position and the mattress-support begins its` operation of opening.
Various'other obJects and advantages of the invention will hereinafter appear, fand the novel features thereof will be .particularly pointed out in the claims.
Referring 'to t ev drawings: l Figure l'i's a-front elevation of a sofa-bed embodying my, invention, the upholstering .of the black-being omitted and one of the sofa.'be d frame-ends being partly broken away, the s eat being closed butthe back frame elevated;

Fig. 9 is a .detail of the mattress support in end elevation, the parts being folded and shown in the positions assumed by them when stored within the sofa-bed frame.
plan vieiv similar vSimilar numerals of reference indicate similar parts in all the figures of the draivings.
' The conventional sofa-bed frame is employed.` and therefore consists of the opposite ends Qhaving front and rear posts 2 and Siespectively, the latter being connected by the rear cross-bar `41, above which'the rear posts project, as shown. A frame forming three sides ot' a rectangle and consisting of the opposite end-bars 5 and connecting rear bar (i, all formed of angle-iron, serves to connect the opposite ends l. and from the center of the latter bar to points rnear the ends of the cross-bar ll, may extend diag onal braces 7, theivholc structure constituting the back of the sofa-bed frame'. A vertically disposed centrally located channel-bar 8, may be connected at its lower end to the bar'G and at its upper end tothe bar 4, the same acting as an additional brace and' preferred form of whatlis in reality the stationary part of the structure-the sofa-bed Patented Mar. 4, 1919. vapplication ined May 31, i917. seriai No. 171,883.
back be capable of moving vertically above andso as to release 'the-sofa-seat. 'Y In the present instance, however, as will hereinafterappear, I have-provided a movable back that is capable of elevating automatically when the 1nattress support ,begins its opening, or
unlolding movement, the re lrn of the back being made by' hand..
deferring to this part of the structurev for the purpose of a detail explanation, .it will be seen that the frame of the back comprises an upper crown-piece or rail l0, adapted to rest upon the upper ends of the rear posts 3 piece l() and rail l1.
construction ofthe back-frame may best be pairs of guides 16, `through the medium ofv each ofA the rods 14, is secured to the lower end of the rod and at its upper end to an vate the back-frame and the upholstery (notwhich, beyond the bearings, are cranked, as'
of the ends l, a lower parallel rail 11, and short vertical'connecting-rails.12, attached at their upper and lower ends 'to 'the crown- The Iremainder of the seen byv reference to lFigs. l1, 2 `and 3 of the drawings'. Immediately above the rear posts 3, pairs of keepers 13, are attachedto the undersideof the crown-piece l0, and in each pair of keepers is-journaled the upper end 'of a supporting-rod 14, the upper end of the rod being laterally bent at an angle, as at 15, for the purpose. The vertical portions of therods 14 are mounted to reciprocate in which the back-frame as a wholey is raised and lowered. A coiledspring '17, one for eye 18,-on the underside of the arm-piece of the end 1. Thesesprings exert a lifting tendency and when uninfluenced serve'to eleshownycarried thereby, .as shown in Figs. 1', 2, and 3 of the. drawings. Attached to the rearedge of the lower parallel bar ll-of the back-frame, are alining bearings 19, in which is. journaled a shaft 20, the two ends of at 21, and journaled in openings 22, formed in the opposite vertical bars Beyond the latter bars, the ext'remitiesof the'shaft 20' are Abent to form-short cranks 23,'and tothe same areattached liftingsprings 24,' the upjy per ends of vwhich-are attached to a conven-l vious that when vthe springs 24:` are at'that side of tliobearings 22 ats-'which they'iare shownli'n Fig; 2, they withfthe' springs 17,

To cause the back-frame to ascend or-assume its elevated a vfew inches or enough' to cause the Asprings to' advance to a point in front of the bear' to accomplish the same automatically, all as will hereinafter appear. vTo lower the backframe it is 'simply' necessary to pressl the same downward a sufficient distance to cause ,by hand and initiatory to the operation of 'l scribed Vbed or mattress-support, yet I prefer the springs 24; to swing'` to the opposite sides 1 of the bearings 22,l when the springs24 actv5 ing on the crank-arms 23, will serve to lock, the back-frame inits lowered position aboveI f the sofa-seat.v
soA
a series of foldable sections made ofangle- "iron," the sections being pivoted-together in rule-J,omtffashion and therefore capable. of folding one upon the other and of openlng .85pV hori zontalalinement.- The number of sec-v or unfolding -to a point where they arein tions may vary, but. in order to secure a bed of full'length and'yet avoid undue width of seat, l prefer' to employ a comparatively narrow' head-section .26,a main-section 27, a
and a footsection'29, these sections being arl ranged in the order mentioned, .andhavmg their side-bars overlapping and ypivoted, 'as at 30, whereby the sections may be said to be articulated. Ihehead-section26 is supportled Wholly by the main-section 27, andthe latter .is lower-ably supported, in .this instance, by a pair of front and a pair of rear links, designated respectively as 31 and 34.v The front 'links are forwardly curved vand p'ivcted, as at 33,'-to the side-bars of the,
between the meeting ends of the side-bars vma1n=sectionj 27, and at their lower ends to of the main-section 27 and the corresponding 'bars of the headsection 26, the lower I ends of the llnks being pivoted vto-th'eafore' said horizontal supporting-bars 25. The
supporting-bars 25 may ormay' not be em-v ployed, but` Iv prefer to employ them for that the mattress-support and all parts employed )for operating the same thereby becomes a completev unit, may be lmanufactured and.
sold'las such by the metalfbed manufacturer i maker and 'by thelatter vreadily slipped into position (without the en'l'ploymen ofskilled y `-to Vthe 'sofarbed manufacturer or ,frame-*-4 -lent point. of thestationary structure-prefV be noted that the bars 25 and reposif tioned so that their horizontal webs "orf, flanges are reversed-that fof the bars 25 being at. the upper side and those of thebars 5 at the lower side. This/relatively different bo riveted to the bars 5, with the horizontal lformer. 'A pair of angular stop-clips 36,
may be secured to the ends of thebars 5,
and at their front ends extend above the same, sothat when the bars 25 and 5 are once assembled they become immovable. As
a further. means of connectioiibetween these two pairs of'bars, angular keepers 37, may
vflanges of the keepers spaced a 'sufficient distance from those o1" the liars 5 to permit of the eiidwise insertion of therear ends of 35, tliesame'having nuts applied to theirv the bars 25, the front lends of the horizontal webs ofltlie keepers being iiptu'rned slightly for this purpose. When the bars 25 have been slid endwise into positionv under the keepers 37 and assumed their .proper position their withdrawal will be-obstructed by the stop-clips 36. The vfoundation of the mattress-support or bed-portion of the struc ture isthus made secure and the ease and accuraey with whicliit maybe mounted 'in the sofa-bed frame will be readily appreciated.
The pivotal connections between the lower ends of the links 31 and 3 4 and the bars 25, are, respectively transverse tie-rods 32 and ends and serving not only as iivotal connections for the said links but a so as means of connecting the two bars -25 foiming the foundation of the mattress-support or bed. These tie- rods 32 and 85, ina-y be connected by meansl cfa cross-plate 38 (one near each side of the sofa-.hed frame) and 'between the tie-rods a' short rod 39, may connect the cross-plate and bar 25, thus serving` not only to brace the structurebut also as a means for pivoting the lower ends oi' a pair of links 40, to said bars 25. Each of the rods 32, 35 and 38, may have coiled about it, springs 41, (see Fig. the innerends ot the spiings engaging the cross-plate 38 and the outer ends the y rear edges of the three sets of links 31, 4t() adl, so that,- When said links are swung i backward, the springs are placed under tension, and when the parts hereinafter described are being0 operated, the springs `will combine to 1aid in such operation-dial: is, in raising theliiiks to tlieirelevated positions.
L-sliapedc'lip-plates 42, may be secured to c z'ich'of the tr'ackbars 5, near the frontends of the latter,and such plates connected 'by a front tiebar 4K3,v the latter serving as the front brace for the sofa-bed frame.
A pair of opposite togglelin'ks 44 and 45,
pi Vo'ted'together at their ineeting'ends, as at 46, have their upper and lower ends respectively pivoted, as'at 47, to about the centers of the side-bains of the spacing bed-section 28 and to the tie-rod 32. Af link 48, has its,
front end pivoted at the point e6 of the toggle-linksand its rear end pivoted as to a point slightly above the middle of the'` link 40.
A leg 50, is pivoted to'each of the links 4 near the upper ends of the latter, as'at'li,
and near their lower endsare pi'ioted, as at 52, to the forward ends of leg operating links 53, the upper ends of which are p ivv 54, to `the upper ends of the `715 oted, as at links 40.'
Triangular eccentrics 55,' are pivotecl, as
at 56, to the opposite side-bars of the footsection 29, and to one ot 'the angles of eachf ot said eccentrics, there is pivoted, as at'58,
the front end of a link 57, the rear end of said link being' pivoted,.as at 60, tothe link 61, at one side ot the pivot 5 9, of the latter where the foot section joins the Aspacing- -pivoted to the foot-'section 29 'at '59 near section28. These links 63 and 64 are for the purpose of suspending and automatically extending and retractingthe seat-frame 67, when the latteris swung out from and `into ,Y
the sofa-frame. (See Fig. Ll.) For thisv purpose and also to allow the seat-frame to collapse upon the folded bed, vwhen the sofa is in use as such, the bottomof 4the seat-trame is provided with llared recesses (see dotted lines) and Within the'san'ie the -said suspension-links are pivoted,''as at 68.
The two end-bars of the seat-frame 67,l are 70, rigidly secured to and depending from the side-bars of the foot-section'29.
A movable panel or Afiller-board{71,conibines with the front of the sofa-seat 67,- to
- formed. with vertical recesses or guides 69, .i and .such receive corresponding guidefbars close the front of the sofafraine when the n bed is t'olded and the seat is in position for vuse as such, the meetingl edges oi'' the seatl and board being connected by a double rhinge 72, one being arranged at each end, and the two connected by a filler-strip 73. To cover'v f the space between the hinges and the board and seat, a tlexible strip 7l, may be used, the same being loiined ol thesaine material as the. upholstery of the scat. At its rear side, the filler-board 71, has piif'ote'dftoit asf at..
77, a pair ot' short links 75, the opposite'l ends ot which are pivoted, as at 76,-to'the folding legs 50, near the upper ends of the latter. i
The lsofa-seat, wlii'cliisI illustrated.with'4` the usual upholstering' omitted, i's'provided with 4the operatingloop 78.- I
Any desired formy of bedding-clamp may b e employed at the free en d of the foot-section 29, for the purpose of retaining the, mattress and bed-covers in position uponv the mattress-support or bed during manipulations of the latter. Inthe present 1nstance, I have loosely journaled in the' ends.
of the side-bars of the section 2S), a trans- Verse shaft 80, capable. of rotation, and at'- tached fast to the same 1s an angular or L- shaped clamping-frame 79, capable of being raised to form a foot-board, asin Figs. #l and 8, or lowered to form a bedding-clamp, as shown in Figs. 7 and 9.
Projecting `rearwardly from the transverse center of the head-section 26, is a camshaped prong 8l, the free end of which l1s designed to ride in the channeled guide 8,
for the purpose of folding the head-section vof the bed as the folded sections move rearward and downward during the act of storing the same.
Angular cams 82, are secured at each corvner ofv the foot-section 29, and project slightlyin 'advance thereof, the lower end s of the cams being made fast to depending standards 83, formed of angle-iron, secured to said foot-section. The functions o't' these cams are to cause an automatic raising of themovable sofa-back heretofore mentioned, such 'being accon-iplished b y the cams coming in contact with the lower edge of the back when the bed has begun its unfolding vmovement, whereby the lcoiled springs 2+ 'being thrown to the vopposite sides of the bearings for 4the cranked shaft or rod 20, together with the springs 17, serve to elevate the back from over the seat and thereby release the bed from the seat.
Legs Si, are pivoted at their upper ends, as at 85, to the angle-iron standards 83, whereby they are adapted lto fold up out of operative position along the rear edge of the sofa-frame seat when the latter is in v position forv use as a seat, and fold down at anangle thereto to serve as a support for the outer end of the seat and the footsectionwhen the seat is inverted in front of the structure. Any ordinary well-known means may be employed for operating the legs, as, for instance, links Si, may be piv- Oted at their upper ends, as at 85", to the foot-section, and at their lower ends to the legs, as at 86, the latter being connected to the seat.
Pairs of triangular rest-blocks 88, may be located near 'the opposite. ends of each of ythe side-bars o ffthe spacingsection, Athe same forming stops and rests when the spacing section and, the foot section combine with the main-section to form a rectangle, as when folded. head-section 26 will have assuineda substantially vertical position, and in order that Ait may Abe secured to the bed or mattresssupport, so Ithat thel latter actually forms Aand may be handled as a complete unity,
especially when being shippedfthe rear edge of said head-section may be'provided witha lVhen thus folded, the
'lapsedso as to allow the latter to become firmly supported by the folded struct-ure, so that, for the purpose of supporting the seat within the sofa-frame, no further means are required. It will also be seen that by reason of the folding operations of the various coacting links, the main section 27 is' at` the bottom and thefoot section 29fisdiametrically above at the top, these two sections being spaced apart by the spacing-section 28 and the stopblocks 88. 'It will also be seen that the spacing-section 28 forms the front wall of the space between the sections 27 and v29, 'and that the head-section 26, forms the rear wall thereof, so that the four sec-tions form a rectangular space of suiiicient size to rece-ive the folded mattress and the usual covering, the latter and the several sections all being compactly folded in a comparatively small space below the seat.
.Aided by the several springs 41, the manipulator, by grasping the-loop 78, gives the initial upward movement to unfold the bed .or mattress-support. As the entire structure rises upon the supporting- links 31 and 34, the cams S2, abut against the underside of the back-frame, causing the latter to automatically rise, in the manner heretofore dex scribed, and'to' assumethe elevated position 1n which it is illustrated in Fig. 2, wherein 'it is locked by the springs against lowering. The head-section 26 is now unlatched from the foot-Section, and as the opening operation continues, the head-section falls l rearward to the inclined position shown in Fig. 7, the guide Sl'dropping into the channeled guide 8 of the sofa-frame, and riding down the same as the -bed is further advanced in its opening operation until the head-section finally reaches a horizontal position-,see Fig. 4. Through themedium of the links 40, 61 and 57, as the seat-frame and foot-section are inverted or swung out,-
'ward, the triangular eccentrics 55, and standards 66 are turned on their pivots 56, and 59, respectively, and through the me.-`
dium vof the short suspension-links (53 and 64, the seat-frame' is positively extended from the foot-section, being `guide-.l in Such movement by the guide-bars 70.
The opening or spreading of the links 40 and 6l, through the instrumentalityof -the connecting-link 53, serves to swingthe supporting-legs. 50 outward and dewnward fromy their inoperative folded .positions so 'edge'otl the sofa-seat frame. When the footsection and seat have been wholly lowered,
their outer ends are supported by the legs Y Set, which are swung .down automatically by the links 84a, operated by the downward movement ofthe seat as it -separates from the foot-section.
The operation ot' closing is but a reversal of that Just described, it being understood, of course, that the legs- 84 are automatically folded by the retraction of the seat elevated to the position shown in Fig. G. rlhe folding operation is now continued,y the bed readily breaking first at the pivotal points between the foot and spacing-sections and later at the corresponding points between the spacing and main-sections, so that the foot and main-sections are substantially parallel. As this is being accomplished, the legs 50, are automatically folded. The en- 'tire struc-ture is now pushed rearward, in`4 which movement, it swings upon the supporting-linksl and 34, and is gradually lowered within the base of the sofa-franie to the position shown in Fig. 9. As the folded bed assumes this position, the r'car or free end ot' the head-section 26 abutting against the channeled guide, is caused to swing into the position shown in said figure of the drawing, and the latch 90, which may be spring actuated, connects the headsection to the foot-section. The back-.frame is now lowered by hand, so that the lower edge of the said-back overlaps thel upholstered seat to av substantial degree. The springsfll resist the lowering ot' the folded bed structure, thus easing the latter to its lower positiomand also aid in elevating the same.
It will, of course, be understood that the bed-sections support the usual wire iabric,
(it not. being'deemed necessary to herein illustrate the san1e,) and that the latter will, when the sections are folded as shown, envelop the bedding.
During the folding operation, the bedding is clamped and held in position by the clothes-clamp 7i), or some other torni of kindred device, and, in the present instance, when the bed is unfolded for use, the clamp shown may be swung to a vertical position so as to release the bedding and also form an ornamental foot-piece.
