FOLDING BED.

SPECIFICATION forming part of Letters Patent No. 515,686, dated February 27, 1894.

Application filed July 31,1893. Serial No. 48l,931. (No model.)

.To @ZZ whom it may concern:

Be it known that I, KNUD L. HYLLER, a citizen of the United States, residing at Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Folding Beds, which are fully set forth in the following specification, reference being had to the accompanying drawings, forming a part thereof.

This invention belongs to the class of beds which tilt from vertical to a horizontal position upon a fixed upright frame at the head, and it comprises, in combination with the devices specifically pertaining to such a bed, a sofa which, when the bed is folded up, occupies a position in front of it, and when the bed is horizontal is depressed and occupies a position under the bed, but in neither position forms any part of the bed proper, but is merely operated by the tilting movement of the bed.

In the drawings,-Figure l is a side elevation with the outer cheek or inclosing board of the upright frame removed, and certain' other interior linings broken away in part to show the interior mechanism. The parts are shown in full lines with the bed folded up and in dotted line with the bed horizontal. Fig. 2 is a plan showing the bed horizontal, but chiefly broken away and being partly sectional at the plane indicated by the line 2-2 on Fig. l. Fig. 3 is a detail rear elevation ot the upright frame. Fig. 4; is a plan ot the upright frame. Fig. 5 is a detail elevation of a pivoted leg which I employ for Athe foot of the bed when it is horizontal, the

full lines showing it in the position of use and the dotted lines showing it folded up as when thebed is elevated. Fig. 6 is a detail section at 6--6 on Fig. 5. Fig. 7 is a section at the line 7--7 on Fig. 2. Fig. 8 is a section at the line 8--8 on Fig. 7.* Fig. 9 is a detail eleva tion of the bracket or clip which aiords dis' engageable pivotal connection for a link by which the bed controls the movement of the seat. Fig. lO is a detail elevation showing a special form of hinge connecting the bed frame and sliding head frame. Fig. 11 is a section at the line 11-11 on Fig. 10. Fig. l2 is a perspective of a stud plate for pivoting the bed frame to the upright frame. Fig. 13 is a perspective of the bell-crank-lever by which the pivoted bed frame is operated. Fig. 14 is a detail elevation of a clip for securing the leaves of the bent counterpoising spring, showing the stub ends of the springs in place.

I will rst describe, in general outline, the structure employed in my invention.

The upright frame, into which the bed folds np, comprises two side cheeks A A, and suitable brace frames B and C which connect the side cheeks, the former frameat the back, and the latter frame at the bottom. The details of the construction of these frames and their connections to the cheeks are designed with special reference to affording facility in assembling the parts and disconnecting for shipment, or to permit moving the bed readily frorn one position to another, which would otherwise be attended with much difliculty on account of the total dimensions being too great to allow it to pass, either when folded up or extended, through dwelling-house doors of ordinary dimensions. The bed frame D, which is a rigid and substantiall y rectangular frame of ordinary dimensions, is pivoted near the head end to the two cheeks near the lower end ot the latter, and adapted to swing to an upright position between the cheeks or to a horizontal position extending from them. The connections between the bed frame and the upright frame, in addition to the pivots referred to, consists of springs attached to the upright frame and operating upon the bed frame, tending to counterpoise the weight of the latter when it is prostrate.

The sofa seat E occupies a position in front ct the bed when the latter is folded np, and in that position it is supported by parallel links at both ends, which connect it tothe cheeks of the upright frame and is retained in proper position by links which connect it also to the lower end of the bed frame, and which, when lthe bed is swung down, operate to depress it out of the way et the bed and into position under the latter. The forward extension A of cheeks of the upright frame are fashioned at the upper part to form arms for the sofa when the bed is tilted up, and to give an ornamental finish to the head ends of the side-boards of the bed trarne when the bed is horizontal.

The cheeks A A are designed to be made the inside of the cheeks above the level of the bed when prostrate, the lining or inner sheeting a of the arm is made continuous with the lining or inner sheeting a of the upwardly extending portions of the cheeks; but said lining or inner sheeting a, l prefer to f make in the form of a mere skeleton, as illustrated, with a central opening which may be occupied by an ornamental panel or upholstering or drapery. The upper portion of the lining a of the arm is designed to be covered with upholstering. The two cheeks comprising the arms are secured together by two frames, one at the back and the other at the bottom. These frames are similar in construction Which is designed to afford rigidity with the least possible weight, and to adapt them to serve as means for connecting the two cheeks rigidly together in such manner that they may be easily detachable for shipping and easily assembled in setting up the bed. The back frame comprises upper and lower horizontal bars G G, connected by a diagonal bar G', making a Z-shaped frame of metal, the three bars being in one plane and being rigidly secured together or made integral. A second diagonal bar G2 connects the otherwise unconnected ends of the bars G G, and is also rigidly connected to said bars and t0 the other diagonal bar at its intersection therewith. These bars may be covered with wooden bars, the metal serving to afford tenacity against distortion of the frame at the junctions and angles, and the wood giving stiffness to prevent bending. At the four corners of this frame are formed four downwardly open notches g g g g, dac., made in the lower edges of the horizontal bars; and to the cheeks, at the back edges, are secu red in proper positions four angle lugs a2 a2 a2 a2, through which bolts extend, on whichtheback frame may be hung, the bolts entering the notches described, and the nuts on the bolts being then tightened up and binding said back frame firmly to the cheeks and holding the cheeks rigidly in proper relation. The bottom frame is made of bars H I-l H and H2, framed similarly to the bars G G G and G2, and similarly notched, and to the lower ends of the cheeks are secured lugs a3 provided with bolts d20, which are adapted to enter-the notches in the bars H, and be secured by tightening the nuts in the same manner, as above described. By this means, the mere slacking of the nuts Without removing any of them or permitting the escape of the bolts permits the easy detaching of the parts, and leaves no loose parts, as nuts or bolts, to be taken care of or liable to be easily lost during handling or shipping. A similarexpedient is employed to secure the front sill A2 to the forward edge of the cheeks at the lower ends, bolts a4 having their heads secured behind metal plates w10, which are fastened upon the back surface of the molding or pilaster A11, which finishes the forward edge of the arms, and being adapted to enter downwardly open notches A21 near the ends of the sill; a washer and nut on the threaded end of the bolt serving to bind the sill thus firmly in place and adapt it to be disconnected upon the mere slacking of the nut without the removal of the latter.

For the purpose of pivoting the bed frame D to the cheeks I provide stud plates D D', secured to the cheeks upon the inner sides. The bell-crank-levers D2 D2 are fulcrumed at their angles upon the studs D11 D11, which project from stud plates, and to the side-bars d, of the bed frame are secured plates d d', which constitute guards between which the arms D20 D20 of the bell-crank-levers D2 are adapted to be engaged, the edges of said arms D20 being beveled and engaged under the beveled edges of the plates d d', said edges converging, and the arms D20 being tapering to correspond to such convergence, so that said arms, when inserted between the plates and under their edges may be forced into secure engagement therewith. To the cheeks A A are secured also, on the inner side, the leaf springs L L, the lower ends of said springs being made fast, and the springs extending up back of the pivots of the bed to the cheeks, and being connected at their upper ends by chains L L to the ends of the longer arms D21 D21 of the bell-crank-levers. Said arms D21 are provided with several holes C121 at any one of which, on each lever, the chain which connects that lever wit-h its spring may be attached to vary, as may be necessary, the tension of the spring in the operation of the bed or at the limit of its downward movement, according to the weight of the bed which it is the purpose of the spring to merely counterpoise when the bed is at its horizontal position. For the purpose of securing the several leaves of these springs in convenient form for use as shown, I provide the casting L3, having, springing from its web at the lower end, a rectangular loop L30,in which the ends of the leaves may be inserted, and any number, up to the total capacity of the loop, may be bound fast by the bolt 220. From the same side of the web, at the other end, the angle hook L21 projects, in position to permit the leaves to be lodged under it, and a bolt 121 is there inserted through the leaves and into the stem of the hook, whereby any number of leaves may be bound rigidly thereto, giving the leaves two-rigid points of fastening to the casting, which is adapted to be fastened by screws onto the cheek after the desired number of leaves for the spring are thus secured to it. The two arms D20 and D21 of the IIC bell-crank-lever are not in the saine plane,

the arm Dgbeing outside of thelining a ofy the cheek, while the arm D2l is inside of the lining; and this permits the spring and chain also to be inside the lining between the same and the outer cheek, only the arm D2", to which the side-bars of the bed frame are secured, as described, being exposed outside the, lining. i

To the upper edge of the head-board D8 of the bed frame, there is hinged the back screen or panel or curtain frame D4, which is designed to close up the upright frame at the back, concealing the frame B, by which the cheeks are secured together at the back, when the bed is horizontal. The upperend of this panel or curtain frame is guided by means of studs projecting from it into channels pro vided on the cheeks, so that while the bed is horizontal this curtain frame is at its highest point and is substantially vertical, and closes up the rear space between th e cheeks. Preferably, I make this an open frame, which may be filled in the center with an ornamental panel or curtain or upholstery, according to the preference of the user, and to correspond with the panels in the upper portion of the lining ct of the cheeks. For convenience in assembling and disassemblin g the parts, I employ a peculiar form of hinge to attach this curtain frame to the head-board of the bed frame. The hinge proper has one leaf M, adapted to be secured in any ordinary manner by screws to the curtain frame, and thefother leaf, consisting of a tapering tongue M with its converging edges beveled; and l provide a plate H2 having for the tongue a seat or tapering socket bounded by converging lianges m20, under-cut to correspond with the beveled edges of the leaf M', and adapted thereby to receive the tapering leaf when entered longitudinally, and give it accurate position when it is forced in snugly between the flanges. For the purposeof securing it against longitudinal displaceinent,otherdisplacement being impossible in View of the form of the parts described,-I secure to the outer surface of the leaf lvl', a iiat spring M3, having at its free end a `rigid stud m3 adapted to project through a hole m', which is drilled in the leaf M', and into a corresponding hole m2 drilled in the plate M2. Nhen the leaf M is forced into the plate M2, the stud m3, which normally protrades through the leaf, is forced bacl,-lex ing slightly the spring M5, and holding it flexed until the leaf M'Vhas been moved toits final position in the plate, at which point the tained, the bed having been once properly constructed with the platesin the right positicn, and avoids the annoying loss of the screws and the attempt to use screws of improper size, ac.

The legs which support the foot of the bed when it is in horizontal position being necessarily at the top when it is upright, are most desirably arranged so as to be concealed from view in the latter position, since it is difficult to devise suitable legs which will constitute an ornament at the head-piece or cornice of the entire piece of furniture when the bed is upright. I provide, therefore, a finishing lip or cornice D5, projecting from the foot-board of the bed frame, horizontally when the bed is down, and vertically when the bed is up, behind which, when the bed is up, the legs may be concealed; andlconstructaleg which will now be described adapted to be concealed behind this lip, and at the same time adapted to project over it when it is swung into operative position.

N is a plate let into the face of the footboard and flush therewith and secured thereto, and having a circular opening n flanged at the back and crossed at the center by a bar N.

N2 is a circular disk, adapted to enter the opening n, and pivoted to the cross-bar N at the center of said opening and of the disk. From the forward face of the disk N2 there projects a lug N20, which stands a little aside from and above the center of the disl,1e ferring to its position when the leg is in operating position,-and to this lug is pivoted the leg N3. The leg has its upper end bent to extend horizontally,referring to the leg in its position in use,-such distance as may be necessary to reach past the inishing lip or molding D5, and its pivot to the lug N2o is parallel with the extent of the leg proper, and at right angles substantially to the horizontally bent portion N30.

N1 is a rigid linger or lug which projects IOO from the forward face of the plate N overthe circular opening n to a point where it will constitute a stop to arrest the lug when the plate is rotated to bring the leg vertical. The plate being rotated to carry the lug away from this stop,-that is, downward to the position shown in the drawings, the leg, whose pivot is then horizontal, may be swung on that pivot and lodged [iat against the foot-board where it will be entirely concealed behind the finishing lip D5, when the bedis upright.

It will be observed that when the bed is down and the leg in operative position, the presence of the lip D prevents turning the leg on its pivot, and it can only be displaced by swinging it about the axis of the disk, and that it is stopped by the linger or lug N4 against so swinging in one direction, and to swing in the other direction would carry the foot of the lug downward, which would lift the bed from the door.r4 The weight of the bed will therefore tend to resist the only displacement of the lug which is possible,-to wit, that which might be caused by dragging they foot of the bed sidewise on the floor in one direction, and the toe or bearing point of the leg on the floor may be set aside to any extent to increase the tendency of the beds weight to resist displacement of the leg. These fixtures will be made rights and lefts, and secured to the bed so that the legs must swing inward-that is, toward each other, the stop operating to prevent them swinging outward.

The frame E10 of the sofa E is connected by parallel links E E', two at each end, to the cheeks A A of the upright frame, and in the position at which the bed is upright, these links are also upright and hold the sofa seat in position such that the forward bar of its frame rests upon the upper edge of the sill A2. In this position, a link E2 at each end connects the seat frame to the lower end of the bed frame. This connection may be made by connecting one end of the link E2 to the rear link E below the pivot of the latter to the upright frame, the other end being connected to a suitable bracket secured to the lower end of the bed frame. For convenience of attaching and detaching, I employ, as a means of connecting the link to the bed frame, a clip E2, having riveted to it a fiat spring E00, at the free end of which there is a rigid stud 620, which is adapted to project through the eye of the link E2, and into a hole formed in the clip, and thereby constitute the pivot for that end of the link, from which, however, the link may be readily disengaged by iiexing the spring to withdraw the stud from the eye of the link. The proportions of the parallel links E and the link E2, and the location of the several pivots, is such that when the bed swings down the seat is pushed forward and swinging upon the parallel links which support it, moves downward also while it moves forward, so that when the bed is in horizontal position the seat is sufficiently depressed to stand freely below it, and as the bed is swung upright, it, by a counter movement by means of the links E2, lifts the seat again to its position of use.

For the purpose of locking the bed securely in horizontal position, so that the tension of the springs, if it should be made too great, can by no means lift the bed, even though all the bedding should be removed to lighten it, I provide two spring-actuated bolts S S, suitably seated in the side-bars d d of the bedframe near the lower end of said frame, adapt ed to shoot outward into sockets s s on the inner side of the cheek linings. To operate these bolts to withdraw them from the sockets, I connect them by links S2 S2 to the lever arms S20 S20 of a rod S2, which extends lengthwise of the bed at about the middle of its width on the under or forward side, and projects through the foot-board and terminates in a handle S21 by which it may be turned to cause its lever arms to draw on the links and withdraw the bolts when it is desired to disengage them and permit the bed to be swung up. It will be understood that the bolts are constructed in the usual manner so that they spring into their sockets without any action of the operator when the bed becomes horizontal.

It will be observed that the arms D20 of the bell-crank-lever D2 extend in such position that the bed frame can be engaged with and disengaged from them most readily while the bed is horizontal, and that then, the bellcrank-levers are under the full tension of the springs, and that these circumstances would tend to make it difficult to effect such engagement and disengagement, because, to effect the engagement it will be necessary to hold both the levers by hand in the right position at the same time against the tension of the springs, which would require the assistance of two persons beside the one who might be handling the bed frame, and that, if disengaged forcibly in ythat positionJ the levers will be thrown violently by the springs, and might cause damage to the furniture. To overcome this difficulty and render it easy at any time to disengage the bed from the upright frame, I provide the latches T T, which are pivoted on the inner side of the arm portions A of the side-cheeks A near the upper ends of said arm portions, and hang down alongside the cheeks in the plane of oscillation of the lever arms D21, and beyond the ends of said arms, these latches being of such length that, by being swung back, they may pass above the ends of the arms D21 when the latter are at their lowest position,-that is, when the bed is horizontal; and in order to give the latches this movement, I connect to them the links T T', which extend back close along the inner surface of the cheeks and out beyond them at the back of the upright frame where they are provided with suitable handles. To prevent undesired engagement of the latches with the lever arm, springs T2 may be connected to them and to the cheeks, tending to hold them forward of the arms D21, except when they are pulled backward by the links T; and in order to lock them at their rearward position where they may be engaged above the ends of the lever arms D21, the links T may be notched at t', and a pin t2 provided at the back of the upright frame with which the notches may be engaged. By operating these latches, the lever arms D21 may be locked in position which will permit the easy disengagement of the bed frame from the arms D20, and the same expedient will hold said lever arms D20 in proper position for easy engagement when the bed frame is to be replaced.
