OVILA BAIGNE, OF MONTREAL, QUEBEC, CANADA.

FOLDING BED.

To all whom it may concern:

Be it known that I, OVILA BAIeNi, a subject of the King of Great Britain, residing at 19 St. George street, in the city and district of Montreal, in the Province of Quebec, in the Dominion of Canada, have invented certain new and useful Improvements in Folding Beds, of which the following is a specification.

The invention relates to improvements in folding beds, as described in the present specification and illustrated in the accompanying drawings that form part of the same.

he invention consists essentially of the novel arrangement and construction of parts, whereby in the operation of opening the bed, the weight is transmitted through an independent supporting member to a point to the rear of the fixed journal bearing.

The objects of the invention are to devise a folding bed in which the weight may be materially reduced as compared with the casing type of bed commonly in use, to cheapen the construction of such furniture, and to provide a simple mechanism easily operated and adjuste In the drawings, Figure 1 is a perspective view of the bed open. Fig. 2 is a front elevation showing the bed closed. Fig. 3 is a side elevation showing the casing in section. Fig. 4 is a rear elevation showing the casing in section. Fig. 5 is a perspective detail of the suspension member. Fig. 6 is a perspective detail of the operating spring arrangement in the closed position of the bed. Fig. 7 is a perspective detail of the operating spring arrangement in the open position of t e bed.

Like numerals of reference indicate corre sponding parts in each figure.

Referring to the drawings, 1 is an up-right casing, here shown as having the sides 2, the top 3, bottom 4 and back 5, the latter closing in the rear of said casing. The front of said casing is completely open.

6 is a suspension member formed of the bars 7, having the journal orifices S at the lower end thereof and the pivot holes 9 at the upper end, the rod 10, journaled in the said orifices 8 and having the squared ends 11 projecting beyond the outer face of the said bars 7, and the arms 12 fixedly secured on the squared ends 11 of the rod 10.

13 is a helical spring encircling the rod 10 and fixedly secured at one end to a bar 7 and Specification of Letters Patent.

at the other end to the adjusting nut 14, the outer member of said adjusting nut being fixedly mounted on the rod 10.

15 are pivot pins securing the said bars 7 through the pivot holes 9 to the inside face of the sides 2 at the rear corner thereof, said bars extending downwardly inside said casing and supporting the said rod 10 just above the bottom 4. The helical spring 13 is so adjusted as to cause the arms 12 to spring inwardly towards the back 5 with considerable force.

16 is the bed here shown as made on the back of a box forming the cupboard 17, the the outer legs of the bed in its lower position. cornice pieces 18 of said cupboard forming The arrangement of a cupboard to the front of the bed in its closed position is only a convenience, and in fact is only one form of construction, as many other arrangements may be shown or a simple closed in box bed, but in order to make it a useful as well as an ornamental piece of furniture, the on )board 17 is suggested as a particularly applicable form, to which is added the door 19 closing in the lower portion of the structure under said cupboard and forming also a convenient receptacle for boots and other articles of wear not placed in the cupboard thereabove.

20 are pins projecting laterally from the box sides of said bed adjacent to the center of each side, and 21 are rollers journaled on the said pins 20, the said arms 12 from the suspension members 6 extending under said rollers 21.

22 are pedestals fixedly secured in the easing 1 immediately in front of the rod 10.

24 are bearings formed in the pedestals 22 intermediate of their height.

25 are shaft ends extending laterally from the box supporting the bed at the rear corners thereof and j ournaled in the bearings 24, the said bearings and said pedestals being so arranged that the bed and box in its vertical position will be inclosed within the casing 1.

It has already been explained that the arms 12 extend under the rollers 21, therefore there is a continuous strain on the said suspension member 6 and as the said suspension member includes also the means of facilitating the folding of the bed, that is to say, the spring, the weightof said bed in opening will be transmitted by the downward pull to the pivot points of said bars 7 in their upper end and thus obviate the annoyances and dangers incident to the upsetting and falling of the casing which occurs in many of such devices.

In the operation of the bed, what may be called the front side of the cupboard is pulled outwardly, which brings out the complete box bed, the latter turning in the bearings 24 and being supported by the arms 12. The arms 12 as has been explained hereinbefore have a tendency to spring rearwardly towards the back of the casing 1, consequently as the bed moves downwardly, the rollers 21 travel along said arms. In the action of pulling the bed its own weight in its downward movement is continuously against the upward and rearward spring pressure of the said arms 12.

The weight of the bed in its downward movement is thus transmitted through the said arms to the bars 7 where the said weight pulls downward from the pivotal points of said bars. By this arrangement the casing 1 stands firmly on its base because the weight of the bed in operation is contained entirely therewithin and to the rear of the journal bearings on which said bed swings.

The advantages of this invention have been to some extent set forth in the first part of the specification, but it may also be stated that in devices of this kind it has heretofore been necessary to make the casings of a very heavy and cumbersome nature, in order that they may withstand the act of lowering the bed, without upsetting, but in this invention, the casing may be made of light weight and handsome material, thus making it easy to transport and much cheaper to manufacture. The same arrangement of suspension, of course may be applied in other types of folding beds where there is no casing but it is considered as being more generally applicable to folding beds having a casing.

The suspension bars being pivoted at the up er end of the casing adjacent to the rear wal thereof, permit a slight outward swing at their lower ends in the opening of the bed, which relieves any jar on the casing incidental to a rigidly supported bearing, for it is, of course, at the lower end of the said rods that the bed has its inner bearing. This very slight swing of the bearing merely compensates for that first jerk or movement of the casing, usual to such structures, but in bringing the weight of the bed down, the lever arms 12 do not support that weight, because of the longer leverage of the suspension bars 7.

What I claim as my invention is:

1. In a folding bed, the combination with suitable supports and a bed having shaft members extending laterally therefrom towards one end thereof and journaled in said supports, of a suspension member pivotally secured at its upper ends having shorter arms engaging said bed and transmitting the weight of the latter in opening to the rear of the said journaling, substantially as described.

2. In a folding bed, the combination with suitable supports and a bed having shaft members extending laterally therefrom to wards one end thereof and journaled in said supports, of an independent supporting member having shorter arms pivotally connected therewith and fastened at its upper ends and engaging said bed and transmitting the weight of the latter in opening to the rear of the said journaling, substantially as described.

3. In a device of the class described, a bed supported and swinging in fixed bearings and an independent tension member suitably fastened at its upper ends and lending support to said bed and taking through its shorter pivoted arms the weight in swinging and transmitting said weight to the rear of the fixed bearings, substantially as described.

4. In a folding bed, the combination with an open front vertical casing and fixed bearings at the lower end thereof, of a bed structure having shaft ends extending laterally therefrom at one end thereof and journaled in said fixed bearings, and a suspension member secured at its upper ends inside said casing to the rear thereof and having a spring rotated part at its lower end from which extendss orter arms engaging said bed, substantially as described.

5. In a folding bed, the combination with an open front vertical casing and fixed bearings at the lower end thereof, of a bed structure, and' a suspension member formed of vertical bars pivotally suspended within said casing to the rear thereof, a spring rotated rod journaled at the lower ends of said bars, and arms of shorter length than said vertical bars fixedly secured to the outer ends of said rod, the latter engaging said bed, substantially as described.

6. In a folding bed, the combination with an open front vertical casing and fixed bearings at the lower end thereof, of a bed structure, and a suspension member formed of bars vertically arranged inside said casing to the rear thereof, a rod journaled at the lower end of said bars and arms of shorter length than said vertical bars extending from the ends of said rod and engaging said bed, and a helical spring encircling said rod and secured to one of said vertical bars at one end and at the other end to an adjusting nut mounted on said rotating rod, substantially as described.

7. In a device of the class described, in combination, a vertical casing open at the front, pedestals fixedly secured within said casing and having bearings arranged therein, a bed structure having shaft ends extending laterally therefrom at one end journaled in said bearings and roller members extending from the sides thereof adjacent to the center secured to the other end of said helical spring, substantially as described.
