CABINET FOLDING BEDSTEAD.

SPECIFICATION forming part of Letters Patent No. 432,073, dated July 15, 1890. Application filed July 6, 1889. Serial No. 316,730. (No model.) i

To all whom it may concern/.

Be it known that I, BRITTON POULSON, a citizen of the United States, residing at the city of Fort lVayne, in the county of Allen, in the State of Indiana, have invented certain new and .useful Improvements in Cabinet Folding Bedsteads; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form part of this specification.

My invention relates to an improvement in cabinet folding bedsteads; and it consists in the peculiar construction and combination of the devices, hereinafter fully set forth, and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 represents a sectional view of the bed-frame and base, section being made through the center. Fig. 2 is a detail plan view of the hinge, guard, and locking device, showing their attachment to two sections of the rail. Fig. 3 is a side detail view of the pulley and a portion of the case. Fig. et is a rear View of Fig. 3. Fig. 5 is an end view of one of the weights, showing the method of its at tachmenttothe ropesu Fig. 6 is a dei ail view showing the engagement of the flange m with the flange n. Fig.7 is a detail view showing a double flange m and m on the plate M and the engagement of m with the pin n. Fig. 8 is a detail perspective view of the plate N. Fig. 9 is a detail perspective view of the plate M. Fig. 10 is a perspective view of the plate N, provided with a pin 1), instead of the flanges n. Fig. 11 is a perspective view of the plate M, provided with double flanges m and m. Fig. 12 is a detail view showing the engagement of the flanged plate R with the hook s, and Fig. 13 is a perspective view of the plate R.

A represents the case or cabinet, which may be arranged in the form of any preferred article of furniture, such as a dressing-case, bureau, book-case, or sideboard.

C is a drawer showing part of such an arrangement. The rear side of this case is open, except a vertical board 13 is attached on each side, in the inner edge of which is a guidegroove b, in which the pins to of the weights WV are moved and guided. The weights WV are bars of any suitable material, preferably of cast-iron, of sufficient width to give the necessary weights required to raise the bed in its case. The lowest weight is made heavier than the aggregate weights of the others, and is so adjusted to the ropes that it rests near the top of the case when the bedstead is entirely extended. The other weights are adjusted at different places along the ropes, so spaced that as the bedstead is pushed into the case they pass over the pulleys, and thus increase the pull on the ropes to correspond with the increasing force required to raise the bed in the case, it being obvious that the higher the bedstead is raised inside the case the more power is required to raise and hold it. The reverse takes place 011 pulling the bedstead out. The weights passing over the pulley decrease the force. There are two pulleys P on each side of the top of the case A, on which the ropes 1) run, carrying with them the weights W.

The method of attachment shown in Fig. 5 permits the passage of the weights over these pulleys without clogging, the weight riding over the pulleys on the ropes, as is obviously shown in the drawings, and also permits the placing of the weights in any desired adjustment in relation to each other and the work to be done. It consists in making two holes through the weights IV at either end for the ropes to pass through, as shown by the dotted lines in Fig. 5. By this method the tension of the ropes when held firmly extended by the lowest weight attached to them produces a clamping action, which holds the adjustable weights on the ropes at any place desired. Upon relieving this tension by lifting the weight or weights the Weight above may be placed in any other adjustment, the ropes then passing easily through the holes to permit it. This device of using several weights and the method of attachment to the ropes permits such a delicate adjustment of forces on opposite sides of the pulleys that the bedstead can be moved up into its case or withdrawn from it so easily that a child can operate it. The ropes may be of any suitable material.

The bedstead-frame consists of an end or IKO front piece 0 and three or more sections D, preferably five, forming the rail, as shown in Fig. 1. Slats S, on which the bed is placed, are suitably fastened to these sections 1). One of the sections D is firmly fastened to the end piece 0. The other sections are hinged to it and to each other. Apreferable form of hinge II is shown in Fig. 2. There is also a guard F, attached to one end of the section D, to prevent the bed-clothing being caught between the ends of the two sections D when coming together in extending the bed from the case, as will readily be understood by inspection of Fig. 1.

The guard F is preferably attached to and made part of the hinge H, as shown; but it may be attached separately, so as to perform the same function, as shown in Fig. 7. hen the sections D are joined by the hinges H, they are cut out a little, as shown by the dotted lines 25 25, Fig. 2, so as to permit the free action of the hinge upon its joint or pivot.

- There is also a locking device below each hinge on the sections D. It consists of a flanged piece M, pivoted at c and provided with a hook t', flange m, and projection a. A guideplate'N is fastened to either side of the case A, upon which the sections D .slide and are held in place. This plate N is provided with two flanges n n, which project inward, so as to engage the flange m (projecting in an opposite direction) as it passes them. If the flange m be made double, as m m, (shown in Fig. 11,) a pin '11, Fig. 7, would answer the purpose of the two flanges n at; but the method detailed is preferable. It is also provided with a hook or pin 3, which extends upward on the other side of the plate N, so as to engage the flanged end pieceRon the last section D. These different parts of the plate N are preferably in one piece; but they may As the sections pass up, the plate Mfalls down by its gravity and the projection a, engaging the bottom of the slat-piece, limits its motion in that direction. As the sections D are withdrawn from the case, the flange m is engaged by the inclined flange '27,, (see Fig. 6,) and drawn downward. This in passing draws the hook i into engagement with the pin 9, completely locking the sections together. Various ways of adapting flanges and pins for this purpose will readily occur to any one skilled in the art; and I do not therefore confine myself to the particular arrangement as shown. The sections D thus hinged and automatically locked together form, when extended, a rigid inflexible rail, and, when antomatically unlocked, a flexible rail adapted to pass readily up into the case A. The sections D are also provided with pins or proj ections (l, which engage and are adapted to move in the grooves E in the side of the case, v

guiding and directing the movements of the sections D in connection with the rope 13. As the sections D pass into the case, they move over the guide-plate N, fastened on the inner side of the case on both sides, which holds them up so as to insure certainty of action. On the last section D is hinged a headboard 0, which is adapted to be either folded The form of this flange-piece R permits the section D to drop past the plate N and be held securely in place by the piece R resting on the pin 5-, and also prevents further extension.

The operation of my invention is as follows: When the bedstead-frame is partiallywithdrawn, as shown in Fig. 1, it may be closed by pushing the end piece 0 toward the cabinetcase. The weights assist this movement. As the bed-frame passes farther up into the case, the last weight WV passes 'over the pulley P and adds its weight to the others, giving assistance to the operation. The sections are guided by the pins cl, running in the grooves E, and thelocking deviceis thrown outof connection, as hereinbefore described, permitting the sections D to turn upward on the hinges H, as described. WVhen the bedstead is Withdrawn from the case, the sections D are automatically locked together by the locking device, as above explained, as they are successively withdrawn, and when fully extended the end is held in place by the flanged piece R, resting on the hook s, as described. The withdrawal is assisted by the weights successively passing over the pulleys, as described, being so adjusted that the pull on the ropes on the opposite sides of the pulleys at all times nearly balance each other, so that the force to be applied is reduoedwto the minimum, this equilibrium being maintained in like manner in pushing the bedstead up into the case.

In both operations of withdrawal and closing, the cabinet remains stationary, so that articles placed therein are not disturbed in any way by such action.

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

1. In a cabinet folding bedstead, the combination of a case provided with the guides E with abedstead-frame composed of sections D,hinged atthe top and provided with the pins (1, the locking device placed at the bottom of said sections, consisting of the plate M, provided with a hook 1', attached to one section, the pin g, attached to the other section and adapted to engage the hook i, the guard F, the ropes p, the pulleys P, placed at or near the top of the case, the weights W, adapted to be adj ustably attached and arranged on the ropes, the guides b, and the projections w on said weights adapted to move in said guides 11, substantially as described.
