DISAPPEARING BED.

Specification of Letters Patent. Patented Apr. 15, 1919.

Application filed August 17, 1918 Serial No. 250,376.

To all rwhom it may concern:

Be it known that we, ROBERT W. BosT- vwick and GRANT W. BosTwIoK, citizens of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Disappearing Beds, of which the following is a specification.

. Our invention relates to improvements in disappearing beds, and moreparticularly to beds of the class adapted to be vcollapse or folded and stored within a receivin space or recess below the level -of the floor o a room. It has for its object` to provide means for easily and quickly raising or lowering the bedstead together with the covering doors and other parts, whereby to provide when erected a head and foot board which when lowered to the general level of the floor will inclose the entire structure, compactly within the space, and embodies actuating mechanism combined with one of said doors for raising and lowering the mechanism.

The invention also embodies holding and 'locking mechanism insuring the positive positioning and maintenance of parts, together with other features of construction and operation as shall be more fully hereinafter described.

In the drawings,

Figure 1 is a longitudinal vertical sectional view illustrating the apparatus with the bedstead and covering head and foot boards erected;l

Fig. 2 is a transverse sectional view indicated .by the line II, II of Fig. 1;

Fig. 3 is a cross sectional view corresponding to the transverse plane of Fig. 2, but showing the parts collapsed and lowered below the floor level;

Fig. 4 is an enlarged sectional detail view showing the lever actuated operating mechanism as mounted on the foot board and indicated by the section line IV, IV of Fig. 2;

Fig. 5 is a similar sectional detail view showing the locking mechanism for the bedsteadA when erected; and

Fig. -6 is a transverse sectional diagrammatic view showing the head board as erected and the cable connections for the bedstead. Referring to the drawings, we provide a receiving and inclosing body A bounded within the vertical depth of the floor between the ceiling construction below and the ioor level above, and within surrounding flooring joist members 2, of suitable rectangular formation and size to receive the various portions of the bedstead and its parts when lowered, as in Fig. 3.

The several portions ofthe construction `are suspended when lowered, and maintained when raised by head board 3 and a foot board f1, each of which is hingedl at 5 by suitable hinges to the underframc construction, as will be readily understood.

d The head board and foot board are each suitably strengthened and braced by cleats or. battens 6 and trusses 7 having suitable tightening devices, as turn-buckles 8, w ereby to maintain the boards in continuous efiicient condition.

The bedstead B is of any suitable construction, preferably composed of rectangularly arranged framing members of structural form as angles 9, forming the side members of the bedstead, and transverseterminal angle members 10 forming its end framing members. c

The bedstead as thus constructed is adapted to receive and support any suitable spring mattress and bedding, as will be clearly apparent without further descri tion. The bedstead B is designed to e raised by sets or pairs of cables 11, 11 and 1 2, 12, four in all, which. are wound upon the periphery of a-grooved drum or sheave 13 incorporated with or forming a part of a gear wheel 14 in mesh with an actuating pinion 15, each of `which is mounted for operation upon the inner face offoot board 4f. The sheave gear 13-14 is suitably journaled at 16, Fi 2, vand pinion 15 is preferably mounted by rolling bearings 17 around the securing stud center 18, and upon the face of a supporting hub plate 19, secured against the inner face of the foot board. Pinion 15 is actuated by a crank lever 2O having a squared stud 21 projecting into a receiving socket in the outer center of pinion 15, and is preferably made removable by providing it with a securing set screw 22, as clearly shown in Fig. 4. By this means, crank 20 may be quickly adjusted or removed for operation.

Cables

11, 11 and 12, 12 are fxedly secured by their terminals to sheave 13, and pass in opposite directions therefrom around guiding and supporting sheave wheels 23 secured by their housing plates to the inner face of the foot board at each side of the main sheave.

Cables

12, 12, pass downwardly and are secured as at 24 to cast iron brackets 25 which are rigidly riveted to a transverse angle member l0 at the foot portion of the bedstead (see Figs. l, 2 and 5).

Brackets 25 are constructed in the manner Vshown in Fig. 5, whereby to provide a round bearing portion for the cable, avoiding cutting or abrasion. Similarbraclrets are' 'secured to the opposite or head end of the bedstead, to which are secured in 'the 'same manner, the terminals of cables 11, 11, vvhich support the Iother end, and, With 'cables 12", raise and Vlovver the b'edstead evenly. lCables 11, which are considerably longerl than icables 12, pass downwardly from sheaves v23 4around guiding sheaves 26 secured by their housings ateach. endinost 'corner ofthe cavity, to a flooring board bottom 19,7', as clearly shown in" Fig. l'. -Ca'lnlesll continue upwardly pass over supporting and guiding sheave wheels '28, 'and then downwardly therefrom', in the `same manner as cables 12 pa-'ss downward-ly from sheaves 23 at the opposite end, and are secured to the brackets 25 at the head end of lthe Hedsltead, as indicated at 29,

Re' 25% are prferaby jonrna'led in bracliets 25 or in any other suitable bearings a the-four comers er the bed-Saad, .ma assist in reducing ,friction by action ainsi; the 'enter battens 6 of the head and? foot board.

y this means, i't will be seen that as sliea've 13 is rotated in one direction, it will raise the 'bedstead evenly `to its highest position, indicated 'in Figs. 1 and 2, land will, Jwhen reversed, lowe it to its nested position, as in 3.

For the pjur se 'of covering o ver the side spaces of tfe main 'cav-ity A, 'we provide a air of longitudinally arranged' cov'er 'ards 30, 3 0 hinged at 311:0 the inner framing construction and which are connected by cables '32, 32, to the

end members

10, 10, of ltlie bed'stead An intermediate cover board 30? is also suspended 'by c'ables-32il .fromthe bedstead, in 'the 'same manner, llllin fthe intervening space.

y this means, when the bedstead is raised, the14 boards 30 and 30a `Will be likewise raised to the position shown in Fig. pari allel vvith the 4, ;en'eral Hoor surface, and @will be lovvered to the position shov'vn in Fig. 3` bi gravity when the bedstead is lowered. 'Ihese boards or platforms completely obscure the pit, assist in deadening any noise from below, and also provide 'a fire check. Some or all of said platforms may be omitted if desired.

,Cables 1 1 'and 12 are connected by a suit'- 'able link 33 to single cables 34, one above and 'the other below', ea'cfh 'fitting into lits particular V,1g,`roo\'7e around 'sheav'e 'Wheel 13, the dircumiference of which is of ample Vdiine'nsions to insure suicien 'cable 'travel 'Said 'cabi for complete raising and lowering in less than one complete reyolution of the sheave.

Head board 3 and foot board 4 are, when erected, iixedly held in position by bracing bars 35 pivoted at 36 at each side portion of the cavity A, to suitable bearings thereon, and rovided with retracting` tension Springs 3g, connned at 38 to the inner shortened arm of brace 35 and at 39 to a holding bracket respectively, as `clearly shown i'n Fig. 1;

The onter ends of brace arms 35 are turned at right angles providing a bearing and locking terminal rod Zl() which, When the .head-and foot bfoa'rds are erected, is in'- serte'd in a lholdingr clevis or bracket 41, a series of four such brackets being provided at suitable positions alfonlg'the under edge portion 'of the'head and-foot boards re ectively.` Brace are also in e' ect -have/'rs which assist in the raising 'of the head and foot boards, Vand also in the rewriting loff the fame, by action or 4springigs 37. Mounted upwardly extending journal bearings 'or braplret's 42, on *cross

nienbers

10, 10,03? the bedstead, is a transverse rod 43 provided 'at end with a xedly secured loclring arm out afo'ro'ss the termi-nal 40 ci brace r35, whereby' to ixedly hold the sa'me in posiv"tion, and 'also partly assist in snpporting ,the bedstead. Rod 43 is provided, beit-'Ween rocking farms e4, wnh a lever arm 455 to which is delineated, at each and, a eab-ieee. e passes larou'nrl J'the bearing' Toller 47 and atfth'e inddie, each cable is ennect- 'ed by spring 48, 'the cable strands and spring being thus located closely adfanent the general supporting level for the Inattress. The Weight of the @coupant on the mattress, supplementing 'the tension of 's'pI-ing48, tends to vpull dov'vn on `'each lefvei arm 45 and to hold the locking 421, *14, in outwardly 4thrust posit-ion, as in 5. When such tension is relie ed, upon-removal of the Weight rocking arni's44 are automatically' retracted by springs 459 'engaging shorter lever arms 50 tornred integral with the holding portion foi? lever 11:5, tl'irovv ing arms 44. backward'ly *from 'engagement with rd 40.

The consructio'n and L-operation of the invention wil be readily understood and appreciated from th and especially by accustomed to the use of disappearing Ebeds. "It provides' `an vextremely compact and selfe foregoing descrifpition,

contained construction, easily capable of being 'quickly v'collapsed or erected, and is composed of comparativly few parts. It 'is continuosly reliable in tha-t it provides against possibility Lof lcollapse or 'failure under strain, 'and'is 'Well adapted to the objects in view.
