WALL-BED.

' Appncation med october 7,

To all whom it 'may concern:

lle it known that we, lalumaN ll. Hemi-Es and lViLLiAM A. MATnEsoN, citizens of the linited States, residing at Chicago, in the county of Cock and State of Illinois, have invented certain ne.' and useful Improvements in VVall-Beds, of which the follow- ()ur invention relates to wall beds, and refers particularly to various improvements which tend to give the beds superior operating qualities.

The wall beds which formthe subjectmatter of our intention are of the type which fold upwardly into a suitable recess, and n'iay be lowered for use.

It is one of the objects of our invention to provide means by which in folding the bed upwardly into its closed position or lowering it. into the'position in which it is used, the bed may be checked so that there will be no liability for the bed to violently come in contact with the casing, in the' tirst case, or in contact with the Hoor in the second ease. We accomplish this resultby means of an improved check, as will be de scribed in detail hereafter.

A. further object of our invention consists in the use of an escutcheon plate on the bot\ tom of the bed, thisl plate. being made in such manner that when the bed is raised into its closed position'the legs automatically more into the slots within the eseutcheen plates. In this manner a very pleasing bed, when in its vert-ical position. I

ik further object of our invention consists in the use of a eight bracket which is adjastably attached to the pivot bracket of the bed so that by placing the weightln'aeket in the proper position the desired zunmint4 of force may ire obtained for moving the bed from itsI lowered operative position to its cle-sed position.

A further `object of our invention conlVe have found that it is particularly advantageous to use weights which are curved on their ends so that a desired position of the center of gravity is obtained, and the Weights readily clear the Hoor when 'the A still further object of our invention consists 1n the use of pivotal means for supporting the head piece of the bed on the end Specification of Letters Patent.

piece so that. the head piece always rein-.tins in a vertial position no matter in what position the bed itself may be placed. This construction is of particular advantage inasmuch as it allows the use of a' much higher-'head piece than it has formerly been possible to employ.

i still. further object of our invention consists in the provision of readily operable 'locking means by which the bed is locked in its lowered position, and all possibility of its automatically closing is avoided until the locking means has been released.

A still further object of our invention consists in the use of a special form of leg, which is so constructed that when the bed is brought .to itslowermost position the end ofthe leg slips into a recess and is securely locked in position, while at the saine time swinging of the leg beyond a predetermined position is avoided byv means of a suitable abutment member.

These and other advantages of our in- -veution will be more readily understood by reference to the accompanying drawings, in

whieh Figure 1 is a longitudinesection taken on the line l--l of Fig.' 2, the bed also being shown in dotted lines in its raised position; Fig. 2 is a transverse section taken on of Fig. l; Fig. 3 is a front eleva-tion showing one of' the escutcheon plates nsed on the bottom of the bed; Fig.

-l-` is an elevation of the pivot casting at Ataehed to the side wall of the recess `1n which the bed operates; Fig. 5 is an enlarged transverse section showing the lock ing mechanism used for the bed; and Fig. is an enlarged fragmentary side elevation and partly sectional view showin one of the legs and the abutment mem er and locking means for holding the same in4 position.'4 l

The bed of our construction is designed to operate within a recess having the side walls 10, the bottom 11 and the rearY Wall 12. To each of the side wallsflO is attached a pivot bracket 11, having therein the circular recess 12, One of these. brackets is also constructed with a'horizontal locking rib 13, the object of which will be explained hereafter.

. The lo'cd itself consists of a bottom 14,01? wood or other similar material, in which a mirror 15a may be mounted if so desired.

lil

Attached to the bottom, 14 are a pair of escutcheon plates 15, each of which has the knob 16 by which the bed may be pulled into itnlowered position. Each escutcheon plate has a slot 17 adapted to receive the leg 18. Attached to the bottom 14 and registering withthe slot 17 in each of the escutcheon plates is a bracket 19, having the abutment member 20 and the locking projection 21. This bracket is also provided with the side plate 22 ha ving thereon ,the pivot or pin 23. The leg 18 has at its upper portion tbc elongated slot 24, through which the pivot or pin 23 passes. lt will be evident that while the bed is being lowered the leg 1 8 will, on account of its tree rotation on the pivot 23, always occupy a vertical, position, and, finally, just before the leg hasV struck the floor the parts will be as represented lin full lines in Fig. 6. It willbe impossible for the leg 18 to swing to the right farther than indicated in Fig. 6, inasmuch as the projection of the leg 18 will come in contact with the abutment member 20. As the bed continues to be -lowered the bracket 19, the bottom 14 and the escuteheon plate 15 will move into positions indicated in dotted lines, and the `"as 1j 1,28 also extends between the foot brackets 26.

vlocking projection 21 will descend tand en- "age one side of the projection 25 of the eg 18 so that the leg will be securely locked in osition and can not move.

. tt-ached to the foot of the bottom 14 are y alpair of foot brackets 26, between which extends the end rail 27, preferably in the form of an angle iron, while the toot piece "f Mounted at thetwo sides of the head end of tbe bottom 14'are the two pivot brackets 29, each of .'hich is provided with a lug 30 projecting into the corresponding recess 12a of the brackets 11a. Securely fastened with-- in suitable concave grooves 31 of the pivot brackets 29 are the two side rail tubes 32, vthese 1side rail tubes also being fastened to -correeponding recesses in the foot brackets 26. Extending between the Apivot brackets.

n 29 is` the end rail 33, preferably in the form of an, angle iron, and also fastened to the two pivot-brackets 29 is the metallic end frame 34, which, also, preferably consists of angle irons. A wood panel 35 extends over the head'end of the bed, and suitably fastened to the end frame 34 and the end rail 33.

Fastened to each of the pivot brackets 29 is a weight bracket 36, having the projections 37 and 38. The projection 37 is provided with the slot 39, while the projection 38 is provided with the slot 40. A bolt 41 passes through the slot 39 and bolts 42 pass through, the slot 40. It will thus be evident that by loosening the bolts 41 and 42, cach ot the weight brackets 36 may be adjusted to a desired position. Extending between the weight brackets 36 are the Weight rods 43, on which the weights 44 may be mounted. These Sits end with the handle. 55.

raised.

clear the floor when the bed is raised tronr its horizontal to its vertical position, and are provided with the' slots 115, for attachment to the weight rods 43. lVhcn the bed bottom 14 is in a horizontal position the center of gravity ot the weights 44 is preferably in a slightly lower plane than that of the pivot 30, so that when the bed bottom raised toa vertical position this center of gravity will be carried slightly to the right ot the vcrtical plane of the pivot 30, thereby causing the weights to exercise a, certain checking elfect in the last part oi" the closing' movement oit the bed. lt it is desired to vary the position .in which the bed comes to rest in its substantially vertical position, the weight brackets may be suitably adjusted to obtain the desired result.

One of the pivot brackets 29 is provided with a recessed cap plate 46, within which ed on the rod 54, which extends through one of the side rail tubes, and is provided at It will now be apparent that as the bed is lowered into its final position the locking member 47 will move upwardly until it passes the locking rib 13, and will then be moved into the positions indicated in Figs. 2 and 5, .on .acy count of the pressure of the spring 49. In order to release the locking member 47 by moving it to the right it is only necessary to turn the handle 55 in a clock-wise direction, whereby Vthe locking member 47 will be moved to the right and the bed may be .Pivotally connected to the inner corner of the recess within whichI the bed operates is-the rod 56 of the check 57. The opposite end .of this check is provided wit-h the slot 58, within which the pin 59, mounted on the weight bracket 36, is adapted to operato. The check'57 has the cylinder 60, which is mounted integrally with the rodsGl, while on theend ofthe rod 56 is mounted ajpiston movable Within thecylinder 60..

To the upper portion of the frame 34 are attached the bearings 62, through which passes the rod 63 ofthehead piece 64, this head piece being suitably connected with the side walls 10-ot the recess so that it will always maintain a vertical position. For the sake of simplicity this connection has not. been shown in the drawings.

Attached to the bottom 14 is a hood, whic is preferablyof wood, and consists of a 139 member 6 5 and almember 66. These members coperate to prevent the 'weights from heilig visible when the bed is either in its lowered or its upright position.

Having'thus described the 4Various parts which are used in our invention, theI operation of the same may now be readily understood: Let us assume that the bed is in fits lowered position. Vhen it is desired .to raise the bed, the handle 5-5 is turned, where` by the locking member 47 is released from the locking' rib lZ-l. The bed may now be raised, and as this happens the legs 1S first assume the position shown in -t'ull linesI in Fig. (3,.and then swing around into the recesses 17 of the escutcheon plates l5 when the-bed is in its final closed position. the bed is swung up on the lugs 30 as axes the weight brackets 56 and the weights 44. move down .until they finally assume the positions shown in dotted lines in Fig. l, while the weight Casing G5 moves u'p into the position shown in' dotted lines, lt it is found that the counter-balancing action ot the weights 44 is too-great, the weight brackets 3G may be slightly lowered, thereby correspondingly lowering the center of gravity of the weights 4l, whereas, ii it is tound that the action is too little, they may be correspondingly raised. lVhen the closing action starts the pin 59 on one of the weight brackets 36 moves down within the slot 5S until it strikes.

v the slot 5S until it encounters the outer end of this slot. The cylinder t3() is then movedout, but. on account. otl the construction of the -valves in the piston` within the cylinder G0, resistance is now offered to the outward movement of the cylinder (i0, and the bed is checked in its closing until finally it reacties the. uprightI position indicated in dotted lines in liig. l. (h1 the other hand, when the bed is closed and it desired to open itinto operative position, the knobs it; on the escutcheon plates l5 are taken hold oi and the bed is pulled down against the .\--ligbt. resistance oll'ered by the counterbalaneing weights 44. 'lhis reverse motion o'li the bed will enlise. the check to act in a similar manner to that already described but. with the mction ot' thesev several parts ,occurring in reverse order. \\'hen the bed has reached a position slightly above the horizontal` the counter-bnlnneing action ot the weights lt exactly neutralizes the tendencj.' ole the bed l'rame to mov'e down, so that the bed is brought to its filial open horizontal position by being manually pressed down. In this way the vbed/is checked both near its closing point, when it is raised, and near its final opened position when it is lowered; but in moving from one position to the other the initial part of the movement is always free. The. two legs" 1S keep intheir vertical `po:;itions as th bed is lowered, and, tinally, are/ locked againstmovement. in the manner/ heretotore described.

tinal lowered positien the locking member' -lT snaps into engagement with the locking rib 13/ and it is impossible to raise the bed until t'ltisv locking member is released.

As previously described, when the bed is opened auth loweredthe head piece G4 al ways retains its vertical position, inasmuch as the rod.(3 is rotatable within the bearings It will he lapparent to those skilled in the artthat many changes could be made in the Idetailed construction ot' the `various parts which we have described without deF parting from ei t her the spirit or scope of our invention.
