FOLDING BED.

SPECIFICATION forming part Of Letters Patent No. 379,449, dated March 13, 1888.

(No model.)

To all whom it may concern:

Be it known that I, JOHN GoNDELL, of the city, county, and State of New York, have invented certain new and useful Improvements in Folding Bedsteads; and I do hereby declare that the following is a full and exact description thereof, reference being-had to the accompanying drawings, and to the letters of reference marked thereon, making a part of this specification, in which-- Figure 1 is an elevation in perspectiveof my improved folding bed; Fig. 2, a side elevation thereof with the head-case in section; Fig. 3, a cross-section in line a; 00 of Fig. 2, illustrating the arrangement of the counterbalancingsprings; and Fig. 4, a sectional view of one of the spiral springs enlarged, illustrating its attachment to the bed-bottom.

Similar letters indicate like parts in all of the figures.

The object of myinvention is to simplify the construction of folding bedsteads and increase the convenience and comfort thereof.

It consists in the combination ofdevices,hereinafter fully described, to operate as set forth.

In the accompanying drawings, A A represent the side hoards of the head-case and support for the bedstead, which is constructed, as is customary, with an enlarged base, B. The back D of the headrase may be composed of two doors, a a, hinged to open centrally.

The bed bot-tom is constructed ofside boards, E E, which are. u nited at head and foot, as usual, by transverse boards and bars,and it is finished with a closed bottom, F, of thin boards, fitted between the side boards to support the mattress and bedding. This bed-bottom is pivoted to the head-case by means of cars G, (see Fig. 2,) secured to each side board, E, to project be yond the lower edge thereof at a point removed from the inner or head end of said sideboard. The distance from the end of each side board to its ear G is at least equal to the width of the board, so that when the bed-bottom is turned upon said ears as a pivotal axis the center of gravity shall be carried within and beyond said axis as the bed-bottom approaches and attains a vertical position. (See dotted lines, Fig. 2.) These ears are'pivoted to offsets H H on each side of the base of the head-case by means of pivot-pins b b, secured to said offsets, or by a pivotal rod extending from the one to the other, and the bed-bottom is thereby neatly hinged to said head-case at a suitable height above the floor.

To facilitate the movement of the bed-bottom as it is swung up and down upon its pivotal axis, one or more coiled springs, I, (see Figs. 2'and 3,) are fitted under said axis within the head-case, and an arm, L, projecting radially from each spring, is connected by a cord or strap, J, with a folding head-board, K, which is hinged to the fixed headboard of the bedbottom to form an extension thereof, and in manner to be free to fold forward when the bed-bottom is swung up and to open out and become fixed when it is swung down. Each spring I is so adjusted as that when, by the lowering of the bed-bottom, the radial springarm L is drawn up the spring is thereby coiled and compressed and brought under tension, so that its resiliency is brought into play primarily to actuate the head-board, and furthermore to facilitate the lifting of the bed to fold it up into the case. As the bed-bottom approaches a vertical position the actionof the spring ceases.

Where two independent coiled springs are used, their radial arms L L are coupled by a link, U, (see Fig. 3,) which is adapted to be held and to be moved longitudinally upon the radial arms by means of nuts V V, which are run upon said arms, the arms being threaded to receive them. By this means the leverage upon the springs may be adjusted at pleasure by moving the link to and from the coils. lVheu the springs lose their original power, the link may be placed nearer the coils, so that they will operate with greater force.

Where but a single spring is used, the radial arms may be made in one continuous piece in the form of a loop uniting the two opposite coils of the one spring, as indicated by dotted lines in Fig. 3.

The contact ofthe folding head-board K with the back of the head-case as the bed-bottom is folded up serves to .fold said head-board over, as shown by the dotted lines in Fig. 2.

The outer end of the bed-bottom is provided with folding legs lWI M, hinged to the outer face of the foot-board N at its lower edge, so as to fold in under the side boards, and the crosspiece, which connects the legs above the hinged connections thereof, bears against the footboard when thelegs are extended and are parallel therewith, and affords them a support in this position, as shown in positive lines, Figs. 1 and 2. The foot-board N is also provided with an extension, N, hinged to the upper edge thereof, to fold inward and overlap the bed-bottom, and thereby confine and hold the mattress and bed-clothing in place thereon when the bed-bottom is turned up. The folding foot-board N and the folding legs M M are both firmly braced when opened out, and are locked when folded in by means of a curved link, P, pivoted to the outer edges of the one and the other on each side of the bed-bottom, in front of the axes of the hinges when the legs and head-board are opened out, as shown in Figs. 1 and 2, said link P being pivoted to the I edge of the footboard a short distance above as well as in front of its hinged connection and to the edge of the leg M close to its hinge and in front thereof. As a result of this peculiar pivotal connection of the link with the hinged foot-board and legs, when the two are opened and straightened out the'legs are locked by the link P and cannot be moved until the foot-piece N is folded in, as shown in dotted lines in Fig. 1, and when both the legs and foot-boardarefolded in the foot-board is locked, so that it cannot be moved until the legs are opened out.

I claim as my invention 1. The combination, with the bed-bottom frame, of a foot-board hinged thereto at its top, a pair of connected legs hinged thereto at the bottom, and a link connecting the two in front of the axes of the hinges when the same are opened, substantially in the manner and for the purpose herein set forth.

2. The combination, in a folding bedstead, with its head-case and the bottom frame hinged thereto, of a head-board hinged to the frame, a coiled spring fitted within the case, a radial arm projecting from said spring, and a strap connecting the arm with the folding headboard to actuate the latter, substantially in the manner and for the purpose herein set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
