SPECIFICATION forming part of Letters Patent No. 445,629, dated February 8, 1891. i Application tiled April 10, 1889. Serial No. 306,740. (No model.)

Vthe following to be a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specilfication.

My present invention, while applicable in part to a variety of types of folding beds, has

i relation more particularly to that ela-ss of fold ing beds wherein the main bed-frame without folding at its center is swung up into a vertical inclosing casing or cabinet.V

My invention consists in the various novel features of construction hereinafter described, illustrated in the accompanying drawings, and particularly pointed out in the claims at the end of this speciiication.

Figure l is a View in vertical section through the bedframe and the inclosing casing, the bed-frame being shown in open orunfolded position. Fig. 2 is a view in vertical section through the inclosing casing at one side of the bed-frame, this bed-frame being shown in closed position and in side elevation. Fig. 3 is a back view of the bed-frame and inclosing casing. Fig. a is a detail view in crosssection through one of the upper pivot-plates, through one of the swinging arms, through a guide-bar and stud or roll, showing also a portion of the bed-frame and of the inclosing casing. Fig. 5 is a detail front view of the clamping-bar and its connected parts. Fig. 6 is a detail view,vpartly in side elevation and partlyin vertical section, of the clampingbar and its connected parts. Fig. 7 is an enlarged detail View of one end of one of the straps that connect the swinging arms with the bars for moving the hinged legs. Fig. 8 is an enlarged detail View showing the manner of connecting one end of the woven-wire mattress. Fig. 9 is aview in vertical section through the inclosing casing, the bed-frame being shown in side elevation and in folded position, this view illustrating'V modified features of my invention. Fig. l0 is a View similar to Fig. 9, showing the bed-frame turned down. Fig. 11 is an enlarged detail view,

partly in side elevation and partly in section,

of one of the bottom pivotplates' shown in Figs. El and l0. Fig. l2 is a detail perspective View of a part of the inclosing casing, showing the receptacle for wash-bowl and pitcher. Fig. 13 is a View similar to Fig. l2, but showing a modified form of support for the wash-bowl and pitcher.

A designates the sides of that portion of 6o the inolosing casing into which the bed-frame proper B will be received when the bed is in folded or closed position, and A denotes the upper portion and A2 the lower portion of the main casing, which will constitute a cabinet when a cabinet is to be employed.

The main bed-frame B consists of suitable side rails l) and b and suitable head and foot boards b2 and h3. Between the side rails Z1 and b', adjacent the headboard b2, extends 7o the cross-bar b4, with which will be connected, by suitable adjusting-screws 2, the tensionbar 3, to which is attached one end of the woven-wire bed-bottom 4, the opposite end of this bed-bottom being connected to a crossbar 5, extending between the side rails b and b', by means of the clamping-bar 5i, that is attached by screws to said cross-bar.

In order to more securely retain the end ofA the wire bed-bottom between the cross-bar 5 8o and clamping-bar 5, I prefer to form the abut-ting edges of these bars of irregularoutline, as more particularly seen in Figs. l and S, so that the wire fabric will be crimped and tightly gripped against danger of slipping. The adjusting-screws 2 will pass through the tension-bar 3,and will be provided with suitable set-nuts 6, whereby the position of the tension-bar 3 will be determined in order to secure the proper tension of the woven-wire 9o bed-bottom- I connect the side rails l) and b with the inclosing casing by means of pivotal swinging arms or links C. One of these swingingarms or links C will be attached at each side of the head portion of the bed, and each of these arms or links will be provided with an eye atV each end, the eyes at the lower ends of the arms C being fitted over the hubs 7, that project from the pivotplates S, that in the conroo struction illustrated in Figs. l to i are shown as bolted to the inner face of the sides A of the main casing near their bottom, while the eyes in the upper ends of the swinging arms board thereof.

C will fit over the hubs lO of the pivot-plates 11, thatare affixed to the side rails b and b of the bed-frame at a distance from the head- On the inner face of each of the sides A of the inclosing casing is affixed a suitable guide D, within which Will travel a friction roll or sleeve 20, that is carried upon a suitable stud or pin 21, projecting from the plate 22, that is attached to the ends of the head-board b2 near its upper portion, the inner flange of the guides D serving as rails for the friction rolls or sleeves 20. My object in thus connecting the bed-frame with the vertical inclosin g casing by means of the pivotarms C is to enable a very shallow casing to be employed,while at the same time a very easy swinging action of the bed-frame is secured.

To the bottom of the sides A of the inclosing casing, or at other convenient points, are attached, by suitable staples or eye-plates 30, the lower ends of the coiled springs E, the opposite ends of these springs being connected to a staple or eye-plate 32, that is affixed to the head-board b2 of the bed-frame about its center.

From the construction of parts as thus far defined it will be seen that if the bed be assumed to be in upright position the bed-frame B will be within the sides A of the inclosing casing and the swinging arms C lie between the side rails b and b of the bed-frame and the sides A of the inclosing casing, these bars being at such timein a position approximately vertical, but4 slightly inclined inward, so that the weight of the bed-frame and the bedding will tend t hold the bed-frame in a'norlnallyclosedV position. It now the bed frame be swung outward, as shown by dotted lines in Fig. 1, the initial turning of the bed-frame will occur by the swinging of the arms C upon the hub 7 of the pivot-plates S; but as the friction rolls or studs 2O are free to travel along the Vertical guides or ways D the weight of the bedframe B will cause these rolls to move upward along the guides or ways D, and consequently will cause the pivot-arms C to swing outward, the bed-frame at such time turning with respect to these arms upon the hubs l0 of the pivot-plates 1l. Hence it will be seen that as the bed-frame B is lowered from its vertical to its horizontal position the arms C will be swung into the oblique position shown in Fig. l, while the rolls will travel up the guides or ways D, and as the frame is thus swung toward a horizontal position the weight of the bed-frame will be counterbalanced by the tension of the coiled springs E, which, when the bed-frame is in horizontal position, will assume inclined positions.

The legs G, which sustain the foot portion of the bed-frame B, are connected by suitable hinges with the bar 5, that extends between the side rails Z) and h of the bed-frame, this bar 5 being preferably rabbeted, as shown at 4l, so that when the legs G are turned into position 'for use the rabloeted portion of the bar 5 will serve not only as a direct support for the upper ends of the legs, G, but the lower shoulder of the rabbeted portion of this bar will serve also as a stop or brace to prevent the outward movement of the legs. This feature of thus connecting the legs G to a rabbeted bar 5 I regard as of importance, because the weight of the rear portion of the bed-frame is thus relieved from the joints of the hinges, and because the outward spreading of the legs beyond an approximately vertical position is avoided. The legs G are automatically turned into position for use when the bedfraxne is unfolded or turned to its horizontal position by means of the bars K, the upper ends of these bars being connected to a block 7c, that is hinged, as at 7e', to the cross-bar 45, that extends between and connects the legs G, while the opposite ends of these bars K are provided with metal straps K the eyes in the ends of which encircle the studs upon the pivot-plates 5l, the hubs of these pivoted plates entering suitable perforated lugs 52 formed upon the swinging arms C. It will be readily understood that, if desired, the straps K may be formed in piece with the bars K if these bars are made of metal, and any other suitable means maybe employed for connecting the bars with the swinging arms and with the legs G. I prefer, however, to employ the straps K', and to connect these straps With the swinging arms C in the manner shown, since a hinged joint is thereby provided which enables the bars to properly move in unison with the movement of the swinging arms C. Hence it will be seen that when the bed-frame is turned from its vertical to its horizontal position the outward movement of the swinging arms C will cause the bars K to turn outward the bar 45, that connects the legs G, until these legs are in proper position to rest upon the floor. My object in extending the bars K in oblique direction from bottom to top of the bed-frame is to insure that these bars shall lie cornpletely under the frame, in which position they cannot be struck or tampered with, as would be the case if they extended at the sides of the bed-frame beneath the side rails thereof.

In order to avoid all possibility of the accidental closing of the bed-frame after it has been swung to a horizontal position, I have provided an automatic latch L, that is pivotally connected to a stud 60, affixed to the inner face of one of the sides A of the main casing near its front edge. This latch L is preferably formed with a beveled lower end Z, having a shoulder Z', adapted to engage with a stud 6l, that projects outwardly from one of the side rails of the bed-frame near its head portion, and the latch L is also by preference formed with a handle Z2, whereby it can be thrown out of engagement when the bed-frame is to be turned into an upright position. Fromthis construction it will be seen that when the bed is in vertical position with- ICO in the inclosing casing the latch will hangin the position shown in Fig. 2, and as the'bedframe is lowered to its horizontal position the stud 6l will ride against the inclined end Z of the latch, thus forcing the latch backward until the stud G1 is above and in position to engage with the shoulder Z', as seen in Fig. l of the drawings, when the engagement ofthe stud Gl with the shoulder Z of the latch will serve to prevent any tipping upward of the bed-frame from its horizontal position.

When, however, it is desired to turn upward.

the bed-frame, it is simply necessary to throw the latch backward, so that the end Z of the latch shall rest upon the opposite side of the stud, after which the bed-frame can be turned up into the inclosing casing and the gravitylatchLwill assume a position to again engage with the stud Gl, when the bed-frame is next lowered.

In order to properly retain the mattress M within the bed-frame when this frame is turned into its vertical position, I have provided a novel construction of clamp next to be described. To the side rails or foot-board of the bed-frame is attached a journal-plate O, having a centerperforation adapted to re- :ceive the hub of the swivel-block 7l, that is provided with abearing wherein is held in a manner free to turn the clamping-bar P. This hub 70 will have its free end upset or riveted, and, if desired, a washer 72 may be interposed between the upset end of the hub 7l and the inner face of the bearing-plate O. The clamping-bar P has its outer end preferably bent at right angles, as shown, and downwardly curved to form the portion P, that will bear upon the bedding, and at the rear end of the clamping-bar P is formed or attached a dog or pawl P2, adapted to engage with the rack-bar o upon the outer face of the plate O. 'lhe clamping bar P will also be furnished with a rib or shoulder p to hold this bar within the swivel-block 7l against longitudiual movement. I prefer to form the pawl P2 as a flat plate bent in the angular form shown, and to forni the swivel block 7l with a groove 74 in its curved portion, so that the clamping-bar P can be connected to this swivel-block by merely turning the bar into such position that the pawl can be slippedinto and through the open slot 74, and after the parts have been thus joined together the posit-ion of the pawl P2 when in use will prevent the withdrawal of the clamping-bar from the swivel-block. From this construction it will be seen that when :it is desired to clamp the mattrass and bed-bottom so that they will be securely retained when the bed-frame is turned into its vertical position :it is only necessary to depress the clamping-bar P, thereby causing the swivel-block 7l to turn, and the pawl P2, by reason of its angular free end with the rackbar o,wwill prevent thembackward movement of the clamping-bar, and will consequently cause this bar to rlnly bear upon the bedding. lVhen, however, it is desired to relieve the bedding from the pressure of the clamping-bar, it is only necessary to press downwardly against the bedding the angular portion P of the clamping-bar until the pawl P2 is thrown out of engagement with the rackbar o', after which the clamping-bar P can be turned freely about its pivot-bolt upward and away from the bedding.

The portion A' ofthe main casingmay comprise suitable chests of drawers A3 or other convenient receptacles; but I prefer to provide a portion of this part of the main casing with a suitable closet to receive a waslrbowl and pitcher. In order to afford a convenient means of holding the wash-bowl in position for use, I provide the inner face of the door A4 of the closet with a shelf or support A5, adapted to swing outward with the opening of the door, and thus permit much more ready access to the bowl than would be possible if the bowl remained within the closet.

Instead of connecting the shelf or support A5 rigidly to the door A4, as seen in Fig. 13 of the drawings, this shelf may be connected to the door by means of hinges, as shown in Fig. 12, so that it can be folded upward against the side of the door, in which position it will be retained by means of a suitable bottom of. When this last form of hinged shelf is etnployed, I prefer to provide the inner face of the doorjamb with a suitable groove a, adapted to receive a lug or projection 0,7, formed at the rear edge of the door and serving to hold the door and the shelf securely in position when the door has been opened and the wash-bowl or other article has been placed upon the shelf. This modified construction of hinged shelf is illustrated in Fig.l2 of the drawings.

In order to enable the inclosing casing or cabinet to be readily taken apart so that it can be conveniently packed or moved, I prefer to form the upper portion A separate from the lower port-ion A2, as illustrated in Fig. 9 of the drawings. In this construction the lower portion A2 is provided with a ledge A, that extends from front to back, being suitably cut away to admit the bed-frame, and the lower part of the upper portion A of the casing will be set upon this ledge A6 and will be set in place thereon by suitable dowels or in other convenient manner. The side walls A, within which the bed-frame will be turned, will be formed of divided sections, the4 lower portion of these side walls being united with the lower portion A2 of the inclosing casing and the upper portions of the side walls A being formed with the upper portion A of the inclosing casing. From this construction it will be apparent that when it is desired to move the bed or to pack it for shipment the upper portion of the inclosing casing can be readily removed from the lower portion, thus enabling the parts to be much more readily handled and shipped. In order to afford ample space for the pillow, I prefer IOO IIC

to form a recess W at the back of the lower vportion of the inclosing casing, this being donc by setting forward the back board tu of this portion of the inclosing casing, so that the necessity of removing the pillows when the bed is to be turned into folded position is avoided, and this, too, without incr-easing the thickness of the inclosing casing.

In Fig. 9` of the drawings the lower pivotplates 8, which serve to sustainl the lower ends of the swinging arms C, are shown as formed in piece with the socket 50, that receives the shank 5l of the sustaining-casters 512, and in this construction, also, the pivotplates 8 are shown as formed with the ribs 54, forming sockets for hubs 55, with which the swinging arms C are provided in this modified construction. I regard this construction of the pivot-plate 8 and its connection with the caster as a very advantageous one, because it not only affords a convenient and cheap means for attaching the caster to the inclosing` casing, but as well, also, it enables the strain and weight of the bed-frame to be thrown directly upon the casters and to be relieved from the side walls of the inclosing casing.

It will be readily understood that instead of forming the plates 8 with seats or sockets to receive hubs or studs on the ends of the swinging arm C the plates might be formed with hubs and the swinging arms with eyes or sockets, as in the form of my invention hereinbet'ore described.

In Fig. 9 I have also illustrated a modified form. of guide-bar D, along which the friction rolls or sleeves 20, projecting from the head-board of the bed, will travel. In

this construction the guide-bars D comprise each a single rail, over which the friction rolls or sleeves 2O will move, and at the top of the bars D are formed suitable seats or sockets d, in which the sleeve or rolls 2O will rest when the bed is turned to a horizontal position. My purpose in forming the bars D with the seats or sockets d is to avoid the danger of the bed-frame accidentally turning upward from a horizontal position in event any considerable weight should be thrown upon its head portion, and it is obvious that when the sleeves or rolls 2O are within the seats or sockets d any pressure upon the head portion of the bed-frame tending to turn it upward will be much more effectively resisted than if straight bars D were employed, as in the construction hereinbefore described. If desired, however, a suitable latch L may also be used in connection with this form of my invention.

It will be readily understood that the details of construction above set out may be varied without departing from the spirit of my invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

l. In a folding bed, the combination, with the main casing and the bed-frame, of pivotplates connected to the main casing for sustaining the bed-frame, said pivot-plates having sockets formed integral therewith to rcceive suitable casters for sustaining the main casing, whereby the weight of the bed-frame will be thrown directly upon the casters, and whereby separate plates for the attachment of the casters are avoided, substantially as described.
