FOLDING-BED.

SPECIFICATION forming part of Y Letters Patent No. 593,922 dated November 16, 1897. Application filed January 14, 1897. Serial No. 619,228. (No model.)

To CLZZ whom it may concern:

Be it known that I, FRANK A. COOPER, of Brooklyn, in the county of Kings and State of New York, haveinvented a new and Improved Folding Bed, of which the following is a full, clear, and exact description.

My invention relates to an improvement in folding beds of the upright type.

The object of the invention is to so construct the bed that the action thereof will be contained entirely in the body of the bed, leaving the casing unobstructed except by the brace-rod employed to strengthen the wings and prevent them from spreading.

A further object of the invention is to provide the body of the bed with a weighted folding head-rest and the base or head portion of the bed with a pendulum or swinging weight when a weight is needed at that point.

Another object of the invention is to provide cam-grooves in the side rails of the body of the bed, adapted to receive rollers carried by the above-mentioned brace-rod, whereby the bed-body is pivoted or hung in the casing. A further object is to provide a removable end wall for each cam-groove, admitting of the body being readily connected with or disconnected from the casing, which removable ends serve as stops, limiting the outward movement of the bed when the latter is down.

Another object of the invention is to so hang the body of the bed in its case that the latter will not tip over should the legs supporting the foot of the bed be accidentally displaced when thebed is down, causing the foot of the bed-to drop to the floor. 7

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth,.

and pointed out in the claims.

Reference is to be ha to the accompanying drawings, forming a art of this specification,

in which similar characters of reference indie I cate corresponding'parts in allthe figures.

Figure 1 is a perspective view of the improved bed, the body of the bed being down or in a horizontal position. Fig. 2 is a verposition and the legs as folded thereon. Fig. 4 is a vertical section through the bed when folded, the bed-bodybeing shown in dotted lines as partially raised. Fig. 5 is an enlarged longitudinal section of the head end of the bed and a portion of the casing, illustrating the manner in which the body of the bed issions at the head of the bed-body.

The casing A consists of side pieces 10, each provided at the forward portion of its lower end with a wing 11, the side pieces of the easing being connected at the top by a backboard 12. A rod 13 issecured in each wing, being held from turning therein by nuts 14: or their equivalents, and the inner ends of these rods are threaded to receive a turnbuckle 14*. These adjustable rods are adapted, primarily, to strengthen the wings l1 and prevent themfrom warping or spreading.

Near the outer end-of each rod 13 a roller 15 is loosely mounted, as shown in Fig. 7, and each roller is provided at itsinner face with a flange 16. A rail 17. is connected by a hinge 21 with the head end of the bed-body B,which is of box construction, and each rail at its rear end is pivotally attached to an arm 18, which arms are pivotally connected with the inner faces of the sides of thecasing A by means of pins 19 passed through one of a shown in Figs. 1 and 4, the hinges 21 being placed upon the upper surfaces of the siderails of the bed-body and the extension-rails 17, the top edges of the extension-rails when the bed is down being flush with the upper edges of the side rails of the body proper.

The inner portion of the bed-body, or that portion which is between the wings and constitutes the base of the body when folded in the casing, is much deeper than the recess of the body, as shown at bin the drawings. In the deeper portions of the sides of the body of the bed cam-slots 22 are made. These slots extend from the inner end of the body horizontally a predetermined distance in direc IOO tion of the foot and are then curved downward in direction of the bottom of the bedbody or its front panel. The walls of the camslots are protected by metal tracks orbindingstrips 23, as is shown in Figs. 1, 2, and 5.

The rollers 15 of the brace-rod 13 travel in the cam-slots 22. The rollers are prevented from sliding on the rods by means of suitable collars, as shown in Fig. 7, and the flanges of the rollers will engage with the inner faces of the binding-strips or tracks 23, thus preventing the sides of the bed-body from being sprung 0r warped, holding the said side pieces likewise in the position in which they are placed, and as the wings are also prevented from warping when the bed is closed the sides of the bed-body will fit quite close at all times to the sides of the casing.

A wear-plate 24 is secured to the inner face of each side board or rail' of the body, extending, preferably, from the front edge to the lower edges of the cam-slots, and a like plate 25 is attached to the said side boards or rails above the cam-slots. A stop -block 26 is hinged to each lower wear-plate 24, and each stop-block extends within the open end of a cam-slot 22, each stop-block being also provided with a flange 27, the said flanges bearing against the upper wear-plates 25 when the stop-blocks are in position, as shown in Fig. 5. The forward or inner faces 28 of the stop-blocks are concaved, as shown in Fig. 4, and receive the rollers 15 when the body of the bed is down or is in its horizontal position.

It is evident that by dropping the stopblocks 26 downward to the position shown in dotted lines in Fig. 6 the rollers may be readily entered. into the cam-slots or removed therefrom as occasion may demand. The stop blocks are held within the cam-slots 22 by any suitable form of latch, that shown in the drawings consisting of hooks 29, attached to the plates 25, entering the eyes 30, secured upon the flanges of the blocks.

The head-rest 31 is in the nature of a board and extends from one extension-arm 17 to the other, as illustrated in Fig. 1, and upon the back of the said head-rest '31 one or more weights 32 are secured. It is ofttimes necessary that more weight shall be used than could be consistently placed on the head-rest. hen such is the case, a swinging or a pendulum weight 33 is provided, which is hung in the deeper portion (2 of the body of the bed, the front panel or bottom of the bed being cut away to admit of the weight being placed in position, as shown in Fig. 5, and the weight is provided with upwardly-extending arms 34 at its ends, looselyhung upon arod 35, which extends from one side board or rail of the bedbody to the other.

The foot of the bed, when in its lower or horizontal position, is supported through the medium of legs 36, connected by a cross-bar 37, the legs and cross-bar having a hinged connection with the front face of the front panel of the bed-body. When the legs are supporting the bottom of the bed, they will be immediately below the foot-board 38, as shown in Figs. 1 and 2, but when the body of the bed is in an upright position the legs will drop downward and lie in engagement with the aforesaid front panel of the bed, as shown in Figs. 3 and 4. The movement of the legs to and from the position named may be accomplished automatieallyin many ways, among others that shown in the drawings, especially that shown in Figs. 2 and 3, in which it will be observed that a bracket 40 is projected from the inner face of the foot-board at or near its center in the direction of the panel of the bed-body. An angle or elbow lever 41 is fulcrumed upon the free end of the bracket 40, the arm of the lever extending in direction of the top of the foot-board being longer than the other member, and the longer member has aweight 42 located at its free end. The shorter end of the lever extends out through a slot 39 in the panel of the bedbody and is pivotally connected with a link 43, which in its turn is pivot-ally attached to the cross-bar 37, carrying the legs 36. lVhen the body of the bed is carried to an upright position, the weight of the legs will cause them to gradually fall in direction of the front face of the panel of the said bed, as shown in dotted lines in Fig. 4, carrying the weighted end of the lever in a downwardly direction until when the legs lie close to the said panel, as shown in Fig. 3,.the weighted arm will be substantially horizontal, and the link 43 and the short arm of the lever will constitute two arms of a triangle. \Vhen the bed is dropped, the weight of the legs will gradually overcome the heft of the weight 42, and by the time the bed-body nearly reaches its normal position the legs will be straight beneath the head-board, as shown in Fig. 2, and the shorter arm of the lever 41 and the link 43 will be in end alinement, or in the same plane, while the weight 42 will be sub stantially in engagement with the inner face of the foot-board. It is evident that in the event the legs should by any possibility be forced from their vertical position while the bed is down and the foot of the bed should drop to the floor it will have no effect on the casing, since the body of the bed will simply move backward, the extensions 17 moving in an upwardly direction.

In closing the bed the body of said bed may be pushed inward, if desired, and thus carried upward, moving upon its pivot, whereupon the extension-arms or the head-rest section of the bed will break away from the bedbody and will be carried to the rear, assuming a position substantially parallel with the front of the bed-body as the latter is carried up within the casing. It is not necessary,

however, that the bed-body should first be carried inward, since it may be lifted straight By reaupward with equally good results.

son of the cam-slots 22 the bed of its own volition, after being slightly raised, will assume a vertical position, and when the rollers reach the curved end portions of the cam-slots, which will be in a vertical position when the bed is fully elevated, the said rollers will constitute a lock for the bed-body, preventing it accidentally dropping or being moved from place when violently shaken or disturbed.-

In Fig. 8 I have illustrated a slight modification of the hanger, which may be substituted for the swinging or adjustable arms 18. This modified form of hanger is in the nature of a segmental bar or plate l5, having an inner track 46 or a cam-groove, the ends of the plate or bar being. secured to the sides of the casing at the rear vertical edges thereof, and each extension arm or rail 17 of the bedbody will under this construction be provided with a friction-roller 44 to travel in the camgroove-4t6 or upon the tracks of the hanger, which will be the side walls of the groove.

- Having thus described my invention, I

claim as new and desire to secure by Letters Patent? 1. In a folding bed, a casing, a rod connecting opposite sides of the casing, a bed-body having curved slots in its side rails, receiving the connecting-rod of the casing, a head rest having a hinged connection with the body of the bed, and a guide carried by the casing, in which the head-rest of the bed has movement, as and for the purpose set forth.
