BEDSTEAD.

SPECIFICATION forming part of Letters Patent No. 550,543, dated November 26, 1895.

Application filed .Tune 28, 1895. Serial No. 554,332. (No model.)

cheap to construct, be capable of adjustment c to render the structure compact, be adapted for receiving upright disposition, whereby the bed will when notin use occupy the smallest possible floor-space, be adapted for easy movement while upright, and,furthermore,be capable of receiving quick and convenient adjustment to a horizontal position for service as a bed.

The invention consists in the particular construction and combination of parts as hereinafter described, and indicated in they claims.

Reference is to be had to the accompanying drawings, forming a part of this-specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a vertical elevation of the bedstead having its parts adjusted to stand upright, showing the side which is lowermost when in a horizontal position. Fig. 2 is a transverse sectional view taken longitudinally through the bedstead while in the position shown in Fig. 1, substantially on the line 2 2 in said figure. Fig. 3 is a longitudinal sectional view substantially on the line 3 3 in Fig. 5, showing the improved bedstead adjusted for service. Fig. 4 is a plan view of the improved bedstead having its parts adjusted, as indicated in Fig. 3. Fig. 5 is a transverse sectional View taken substantially on the line 5 5 in Fig. 3 in direction of the arrows. Fig. 6 is an enlarged fragmentary detail view seen in direction of arrow 6 in Fig. 4, showing one of four similar locking devices that are features of the invention. Fig. 7 is a transverse sectional view of the details shown in Fig. 6 on the line 7 7 in said gure; and Fig. 8 is a transverse sectional View of parts shown in Fig. 7, diiferently adljusted, to indicate another position of the saine.

In constructing the improved bedstead two rectangular frames 10 11 are provided, and, as shown, the frame 10 loosely receives the frame 1l and is therewith connected by means which will hereinafter bedescribed. A suitable number of spaced slats 11SL is secured across the normally lower edge ofthe frame 11, and these slats at the connection of their ends with the sides of said frame are reinforced by the strips 11b, one of the latter being afixed to the inner surface of each side of the frame 11 and seated on the top faces of the slats to which these strips are firmly secured. The frame 11 and attached slats 11 afford an open receptacle for the mattress and other bed-furnishings, and to render it convenient for its designated use suitable and preferably folding supports are provided, whereby the frames 10 11 are together sustained at a proper elevation from the floor whereon the bedstead is located. Two similar folding supports are employed for the bedstead, and these each comprise a light strong frame composed of two leg-standards 12, joined together and held spaced apart, preferably parallel with each other, by two diagonally-arranged brace-bars 12 for each frame. The brace-bars of each leg-frame cross each other and are secured together where they cross, the ends of the braces being firmly attached to the leg-standards near the ends of the latter.

Two exten sion-bars 13 are provided for each leg-frame, all being of like form and dimensions, and the ends of two extension-bars are oppositely pivoted on the upper ends of the standards 12 of a leg-frame. The other ends of the extension-bars 13 project toward each other in pairs at each side of the frame 11, so that sai'd ends may be pivoted on the inner sides of thedownwardly-projecting elongated bracket-ledges 14, secured on the normallylower edges of the bed-frame 11, this pivotal connection of parts being indicated at 14iL in Figs. 2 and 3. The extension-bars of each leg frame are transversely braced by a stretcher-bar 15, attached at its ends on the sides of the extension-bars nearestto the bed-frame llwhen said extension-bars are folded thereon. The relative position of the IOO the end portions of the leg-standards 12 of each frame to bear on the lower edges of the end Walls of the frame 11, and as the point 12b of pivotal connection of said standards on the extension-bars 13 is slightly removed from said bearing ends it will be seen that the legframes Will be retained in folded condition, if so disposed on vthe frame 11, and the turnbutton 1G is made to press on the stretcherbars 15.

Two filling-blocks 17 are preferably affixed to a transverse slat 11n near each end of the bed-frame 11 on the normally-lower sides of said slats, the filling-blocks being so spaced apart in pairs and shaped at adjacent ends of the same that the diagonal braces l2 ofa legframe may occupy the space between a pair of said blocks When the leg-frames are in folded adjustment.

A keeper 18, preferably in the form of a turn-button, is pivoted on one of the fillingblocks of a pair, one of the keepers being provided for each leg-frame, said keepers being employed in connection with other parts to be described for maintaining the leg-frames erect when the latter are adjusted for service. The outer main frame 10 is slightly longer than the frame 11 and is held in sliding connection therewith by means that Will'now be described.

Four bracket-limbs 19, of like form, are secured oppositely in pairs on the inner surface of the sides of the bed-frame 11 near end Walls of the latter, and said limbs are equally inclined edgewise, so that the pair at oneend of the bed-frame will diverge at upper .ends from the pair at the other end of said frame. The bracket-limbs 19 extend an equal distance above the normally upper edge of the bed-frame 11 and are recessed on the outer faces of said upwardly-projecting portions, forming shoulders on the upper transverse edges of said recesses, preferably at right angles to the side edges of the limbs, which Will cause the shoulders to incline at similar angles from the upper edge of the bed-frame, as indicated by dotted lines in Fig. 2. The recesses in the limbs 19 are of such a form as to remove all material therefrom between the inclined top edges or shoulders mentioned and the upper edge of the bed-frame 11, which in effect produces overhanging hooks on the upper ends and outer sides of the bracketlimbs, as indicated in Fig. 8.

A prop-leg 2O is furnished for each corner of the frame 10, Which legs occupy the recessed spaces in the bracket-limbs 19 and ihave their ends farthest from the end Walls of the bedframe 11 pivoted laterally on the inner surface of the side Walls of the main frame 10, the free ends ofthe prop-legs being preferably sloped, as shown in Figs. 2 and The inner surface of each prop-leg 2O is grooved, so that the edges of the groove in each leg will lie parallel with the inclined edges, of the bracket-limbs 19, and on one such edge of each bracket-limb nearest to a groove in the adjacent prop-leg a locking-dog 21 is pivoted, so that it may be folded upwardly and in to the groove of the prop-leg with which it is to engage.

It will be seen that if the main frame 10 is elevated, or, in other Words, slid on the frame 11, so as to permit the prop-legs 2O to receive correct inclination and have assured contact with the shoulders or inclined hook-like edges of the recesses in the bracket-limbs 19, the locking-d ogs 21 may then be upwardly folded, so as to occupy the grooves in the prop-legs and adapt the latter to retain in elevated adjustment the bed-frame 1.0, so that the depth of the receptacle for bedclothing and mattress Will be proportionally increased between the slats 1 1n and the free upper edge of the outer frame l0.

As a means for preventing the displacement of the dogs 21 a spring-catch 22 is preferably employed for each dog and may advantageously be formed of a bent Wire rod shaped as shown, so as to be adapted for attachmentat one end on the edge of one of the bracketlimbs and then bent around the upper end of the latter, so that the free latching `end of the catch may press on the upper end and outer side of one of the locking-dogs 2l `and hold it in place until the resilient catch-piece is manipulated to release the dog.

When the bed-frames 10 11 are connected,

4as has been explained, and the leg-frames are adjusted to project at a right angle from the frame 11, the keepers 18 may be turned so as to have Contact with the leg-frames on the inner sides of a frame member of each, which Will prevent an inward-folding movement thereof, a contact of the upper ends of the leg-frames with the edges of adjacent bed-slats 11n above the pivot-points 12b serving to prevent the leg-frames from rocking an improper degree outward or toward the ends of the bed-frames lO 11, so that the bedstead, as described, may be utilized for its intended purpose. If it is desired to remove the bedstead from a horizontal position, the bedclothing and mattress (not shown) may be secured from displacement by passing a band of any suitable material through the staples 23, oppositely affixed in the sides of the main frame 10, and then securing the ends of the band together. The bedstead, being provided With four casters 24:, may now be elevated on the casters, as represented in Fig. 2, and then be moved on the latter to IOO IIO

any desired point in a room, thus greatly economizing floor-space that is occupied by the bedstead.

Should it be preferred to employ detachable head and foot boards, these may be introduced at the ends of the bed-frame 1l, passing down between the end walls of the bed-frame ll and the leg-frames thereof, the descent of the head and foot boards 25 26 being limited by seating notched portions of their lower edges on the outer ends of the folded extension-bars 13, as clearly shown in Fig. 3.

It will be seen in Figs. 3, 4, and 5 that the head and foot boards 25 26 are removably looked in position by the hooks d, that are pivoted on these parts oppositely in pairs near the side edges of the same, so that they may readily engage with staples or ring-eyes b, which are inserted in the sides of the frame ll, such a locking connection of parts preventing the bedframe ll` from spreading apart when in use. Furthermore, the lower edge portions of the head and foot boards being slid between the end walls of the bed? frame ll and the upright leg-fram es, as shown in Fig. 3, aids greatly in preventing the legframes from sagging outwardly.

It may be preferred to reduce the depth of the box like bed-frame, so that only part of the outer frame l0 will be utilized as a p0rtion of the receptacle for bed-furnishings. In such a case the outer frame l0 may be readily slid downward, if the locking-dogs 2l are released from the grooves in the prop-legs 2O by manipulation of the springscatches 22 and the subsequent outward and downward rocking movement of the dogs 2l, which will permit the frame l0 to drop until the proplegs lie horizontally on the upper edge of the bed-frame ll and the shoulders on the bracket-limbs 19 have contact with the upper edges of the prop-legs, as indicated in Fig. 3.

There are stop-blocks llc formed or secured on the end walls of the bed-frame ll, which will coact with the prop-legs in controlling the degree of downward-sliding movement of the frame lO on the frame ll. It will be evident that the adjustment of the frame l0 to elevate it from the stop-blocks lle and its locking in such an elevated condition as hereinbefore explained will afford a wider base for the bedstead when itis to be stood on one end for movement on its casters to a desired point, and thus render the bedstead less liable to upset when in an upright position.

It is claimed for this improved bedstead that it is simple and inexpensive, is convenient in use, is compact in construction, strong and reliable in all its parts, is adapted for disposal when not in use, so as to occupy but little floor-space, and also is rendered capable of receiving very close adjustment of parts for purposes of handling and transportation.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. In a bedstead, the combination with a bed frame and a surrounding slidable frame thereon, of locking devices near the corners of said frames, each comprising a bracket limb fast on the bed frame and having an overhanging hook-like shoulder, a prop leg pivoted on the slidable frame, said leg being movable below the hook-like shoulder of the bracket limb and having a transverse groove, a locking dog engaging said groove, and a keeper spring for said dog, substantially as described.

2. In a bedstead, the combination of a bed frame, a frame arranged to telescope thereon, prop legs pivoted on one frame with their ends arranged to engage the other frame, and means for holding said prop legs in position when adjusted, substantially as set forth.

3. In a bedstead, the combination of a bed frame, a frame arranged to telescope thereon, prop legs pivoted on one frame and arranged to engage the other frame, bracket limbs on the frame which are engaged by the ends of the prop legs and provided with shoulders to engage the said prop legs, and dogs to hold said prop legs againstmovement when adj usted, substantially as set forth.

4. In a bedstead, the combination of a bed frame, having side and end rails, two eXtension bars at each end of the bed frame7 arranged in pairs opposite each other andhaving their adjacent ends pivoted adjacent to the center of the bed frame, said bars being free at their opposite outer ends, leg frames pivoted to the outer ends of the extension bars and adapted to be folded flat against the under side of the bed frame, and having their outer sides spaced away from the endrails of the bed frame when in their opened position,
