FOLDING BED.

SPECIFICATION forming part of Letters Patent No. 555,441, dated February 25, 1896.

Application filed July 28,1894.. Serial No. 518,880. (No model.) Patented in England November 1, 1893, No. 20,689.

To all whom t may concern: y

Be it known that I, JOHN D. ENNES, a citizen of the United States, residing at Norfolk, in the county of Norfolk and State of Virginia, have invented certain new and useful Improvements in Folding Beds, (for which were granted me British Letters Patent No. 20,689, dated November 1, 1893;) and I do declare the following to be a full, clear, and exact de scription of the invention, such as will en able others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

Figure 1 is an end elevation of a bed einn bodying my improvements. Fig. 2 is a front view whenthe parts are folded up. Fig. 3 is a plan view of the top. Fig. 4 shows several of the parts in the position occupied when the bed is packed for transportation. shows the bed folded. Figs. 6 to 15 show details. Fig. 16 is a side view of a modification, and Fig. 17 is a front view of the same when folded up. Fig. 18 shows the shelf, and Figs. 19 and 2O details of Figs. 15 and 16.

In the drawings I have shown a back frame consisting of rear corner uprights A A.v

These are formed of tubing, for lightness, cheapness and strength. They are connected by an intermediate framework formed of a top bar, B, a lower bar, B', and a supplemental cross-bar B2. The cross-bars B and B are connected by vertical stays or braces b l), which are rigidly fastened to the cross-bars by rosette-like clamps or binders b', which are applied by casting them in place after the bars have been put in the sand.

C O indicate the parts ofthe main frame which extend forward from the corner-uprights A A. Each is composed of a vertical portion c, a short horizontal arm c', a leg c3, and longer horizontal arm c2, which connects the leg c3 with the vertical part c. The upper arm, c', is joined to the corner-upright A, not rigidly, as has been the custom heretofore, but by a pivotal or swiveling joint at c4. By having them thus loosely connected at these points the parts of the beds can be so placed and packed together that a large number of the beds can be stored in a small space durin g transportation.

Fig. 5

The frame parts C O can be turned around so as to lie substantially in the common plane of the back frame, as is shown in Figs. 4L and 5. Then in order to hold the four leg parts a a e3 c3 rigidly in the required places when the bed is set up and in use I employ the peculiar -bracing-frame shown at D. It comprises two bars CZ fl, which are crossed one upon the other and are rigidly joined at the center, as shown in Fig. 14. In the ends of each of these bars CZ there is an aperture d', by which the bar can engage with one of the framelegs. Preferably the parts are so related that the bars CZ can be placed below the lower ends of the tubular legs and have the vertical pintles e of the casters E passed upward through the apertures d into the interior of the tubes, as shown in Fig. 15. l

Vhen a brace or binder similar to that at D is used, the four legs, notwithstanding the presence of the pivotal or swiveling joints, are held with firmness. In fact, the lower portion of the main frame is in such case bettered to a great extent, even when the joints at c4 are made rigid, as by welding, in the ordinary way now followed.

The place of weakness in these beds, re-

sulting from the tendency of the lower ends C of the legs to spread, is in this bottom portion of this main frame. This I effectually overcome by constructing them in the way described. Upon this framework is pivotally supported the mattress-frame. This is shown as having the end bars, F, the side bars, F', and the rails or guards F2 at the head and foot. The end bars or rails, F F, lie close to the frame parts C O and have'passing through them a pivot-rod G. The ends of this rod are j onrnaled in bearings at H, each formed of a heavy wire or rod bent to provide an eye 71. with a vertical bar h' which can be bent, as' at h2, after being passed through the arm c2 of the frame. The rod G can be fastened in the bearings in any suitable Way. I prefer one like that shown, there being a nut at g engaging with the journal g', the latter being seated in a thimble g2 around which the bearing II fits.

It will be seen` that the bed proper or inattress-support F F cannot Aonly be readily rocked around the axis of the rod G, but also that it can be easily lifted out of place when- IOO ever required, as its pivotal parts lie not bclow, as has been customary, but above the frame-arm e2 upon which it rests. The nuts and thimbles can be easily withdrawn, after which the mattress-support can be taken out without requiring the withd rawal of the pivotrod G.

In order to limit the vertical motion of the bed when folding, I introduce bracing and stop-rods I. These are passed through or secured to the legs a c3, and are each formed with a shoulder or oifsct at i, located at such place that the downward-swinging parts of the mattress-frame impinge upon them and hold them in the desired place vertically.

The outer part of the swinging portion of the bed is supported upon legs J .I which are pivoted at 7' to the bars F, and are connected by links J to the legs c3. The parts are so constructed and the pivotal points at y', y", j* and Il are so related that when the bed is folded up the axis at j shall lie somewhat inside of the line which connects the axes at j'2 and y", there being thus provided a togglelock which holds the bed up until it is released by the application of considerable force to one of the parts J or J to move them outward.

To hold the bedding in place, as well as to give the structure a pleasing appearance, I employ a scroll grating or grid, (indicated by K.) It is connected by straps or loops 7.2 to the rear edge of the mattress-frame and by loose sliding rings 7e to the upright bars l) of the back frame.

lVhile the bed is being folded up toward the position shown in Fig. 5 the slide-guides 7.: slip down along the back frame-bars l) and the holder K takes the position shown in. that ligure. lVhen the mattress is down the holder K is moved up and makes an ornamental closing for the open part of the back frame.

The canopy or curtains are suspended from a support at L having a main transverse part Z and carrying-arms l', which are pivotally connected to the rear corner-uprights A A. By pivotingthem in this manner they can be readily turned over when the bed is packed for transportation; but when the bed is in use this curtain holder is supported and stayed by legs l2, which rest upon the arms c of the frame. I secure rigidly to this curtainholder rosette-like stops Z3 at the rear corners,

which prevent the rings l" that support the curtains from slipping beyond the corners, which, as is well known, is a source of great annoyance. At the center I place a stop Z5 for a similar purpose, to limit the inward movement of the rings.

In order to insure sufficient stiffness and strength in that part of the tube C which carries the weight of the mattress-frame I insert therein a rod M prior to subjecting the tube to the bending or swaging action. Thereafter the rod occupies the position shown in Fig. 6, it filling the supporting-arm c2 and extending into the vertical parts c and c3 sufficiently far to insure sufficient rigidity and strength at the bends in the tube.

In order to prevent the bed from accidentally swinging toward the folded position l. employ a lock or stop, as at N. As shown, Ait comprises a bent bar having an arm a and two end parts n', which are pivoied on the cross-bar B2 of the back frame. By examining Fig. l. it will be seen that the bar n of this lock can lie under the inner side of the mattress-frame and prevent it from ineving downward.` lVhen it is desired to fold the bed up, the lock is thrown back by drawing on the cord or equivalent N", which eX- tends to the front side of the bed, such draft thereon releasing the bed from the lock and permitting it to be moved upward.

In order to hold the above-described lock N in its normal position use may be made ol' a spring, as at N2 in Fig. 4, and to prevent it from moving too far a stop Nil can be employed. \Vhen the cord N is pulled the lock N moves away from the stop N against the tension of spring N2.

l is a tube or pipe placed around the stop and stay-rod I to strengthen it and give a symmetrical appearance to the end of the frame.

l) is a mantle shelf and cover. Itis placed at the top of the bed and may be secured in any suitable way. As shown, it is clamped in place below the ornamental balls or top pieces on the rear corner-legs A. Preferably it is formed of sheet metal, which is j apanned or colored so as to be ornamental in appearance, and has an upwardly-turning flange at p at the rear, and a downwardly turning flange at p at the front which comes outside of the front bar l of the canoliy-support Ii. As shown in Figs. 3, 5, and 9, it is made in two parts hinged together, so that one of them can be folded back, as shown in Fig. 5, when the bed is to be packed. This part-1) servesl not only as a support forbooks and other artieles as are commonly placed on a manteh, but also serves to cover up or close the opening at the upper end of the bed to prevent the access of dust and other foreign material. during the time that the bed is folded up.

I have above described my improvenlents as applied to a side-folder; but it will be understood that many of them are just as applicable to end-folding beds. In Figs. 1U and 17 such aconstruction is illustrated. In such case there will not, ordinarily, be any necessity for the positive lock N above described, as so much of the weight is outside of the pivotal line; but the features above set forth can be embodied which pertain to making and relating the parts so thattheyean be compactly arranged for transportation and. can be held strongly in proper place when the bed is set up for use.

I am aware of course of the fact that folding beds having tubular frames have been heretofore made or proposed in several forms. I have myself constructed and patented such IOO IIO

articles. In my earlier patent, No. 444,064, dated January 5, 1891, a structure of this general class is illustrated; butin mysaid earlier bed there were marked differences in comparison with the present construction in the devices and method for supporting, manipulating, and fastening the parts. In that earlier bed the mattress-frame was connected to: the stationary frame by three links, the two; at the rear end of the mattress-frame being so related that when the mattress was down the links had one position relative to each other, and when the mattress was folded up they were both swung into new positions and then had such relation to each other that the longer or outer link and its pivot were outside of the center of gravity of the mattress and mattress-frame and effected the locking of the latter in their upright'position. While under some circumstances that construction had advantages, I have found it desirable for many purposes to provide a simpler and cheaper construction, which shall be strong and durable and yet possess the least possible number of parts. In the present case the mattress-frame is supported upon a iixed pivot, and its weight is taken entirely by the lower part of the forward-projecting end frames instead of being distributed over the entire back frame from the upper to' the lower end. Then in order to strengthen and brace the lower part of the end frames which must carry all the load, and must receive all the strain of the locking device, (which strain is severe because of the downward pressure caused by forcing the pivot j beyond the line of the piv.- otsj2 andj,) I construct these end frames :in the way and provide them with bracing and strengthening devices of the sort shown. Nor do I claim broadly a toggle-lock, as I am also aware that a holding mechanism embodying that principle has been used in many ways; but I believe myself to be the first to have provided a metallic tubular framework for a folding bed of the character herein shown and to have supported -the swinging mattressframe thereon on a ii'xed axis, together with legs and leg-links so arranged in relation to each other, to the said fixed axis, and to the frame that the pivots of the legs and links can be so arranged as to lock the mattress in the upright position and at the same time prevent the severe strain from injuring the lower part of the frame.

l. A folding bed having the rear tubular corner-uprights A, the back frame-bars rigidly secured thereto, the forward projecting tubular frame-bars C C, the hinge-eyes or swivel-joints c4 loosely surrounding the rear tubes A and rigidly secured to the tubes C, said tubes C being bent to form the vertical parts c and c3 and the horizontal parts c' c2, the locking-brace D having arms detachably secured to each of the four tubular legs, and the mattress-frame detachabl'y pivoted directly to the horizontal parts c2 of the frametubes C, substantially as set forth.
