SOFA-BED.

Specification of Letters Patent.

Patented July is, 1916.

7 Application filed April 24, 19 1 5. Serial No. 23,662.

To all whom it may concern Be it known that I, GEORGE LEHMAN, a citizen of the United States, and aresident of Chicago, in the county of Cookand State of Illinois, have invented certain new and useful Improvements in Sofa-Beds, of which the following is a specification.

This invention relates to those devices which are susceptible of a double purpose or use, that is, devices which may be converted from the form best adapted'for use as a bed into the'form which is best adapted for use as a sofa. p

The objects of this invention are to obtain a device of the kind described which is simple in construction, easily understood and operated, not liable to break or get out of order, which can be quickly converted from one of its forms into the other one thereof, and in which a considerable quantity of bed clothing can be stored.

Additional objects are set forth in the description and claims. f

In the drawings accompanying and forming a part hereof Figure 1 is afront elevation of a sofa 'bed embodying the invention, the several parts being in position to use the device as a sofa. Fig. 2 is an end elevation of the device, the several parts being in the same position as in Fig. 1. Fig, 3 is a vertical section, on line 33 of Fig. 1, viewed in the direction indicated by the arrows. Fig. 4 is a view on line 4 l of Fig. 1, viewed in the direction indicated by the arrows, and illustrating the movable parts of the device in end elevation, with said parts in position for use as a bed. Fig. 5 is a perspective of'the movable parts of the device removed from the stationary parts thereof. Fig. 6 is a perspective of the upper end of the stationary part of the device, Fig. 7 is an end elevation of the inner side or face of one of the ends of the stationary part of the device. .A-nd Fig. 8 is an end view of a movable head board, in'avertical plane; said board being illustrated in Fig. 5 in a substantially horizontal plane. 1

A reference character applied .to designate a given part indicates said part throughout the several figures of the drawing, wherever the same appears.

A is a stationary frame, which comprises ends a, table a back (0 clip or support a", and receptacle B. Ends (0 are attached to receptacle B by bolts C and nuts G I make nuts 0 of the kind known as butterfly nuts, so that said nuts and bolts are removable, to permit separation of said ends and receptacle, for shipping purposes.

D is the cover to receptacle B, and is pivotally attached thereto by hinges d.

E is an abutment which is rigidly secured to receptacle B byscrews e.

The table a is mortised, as'at F, and the ends a are provided; with the tongues f (forming tenons), which fit into mortises F, and G areremovable pins which fit in holes provided therefor in table a and tenons f, to rigidly secure said table and ends together.

H are casterson ends a.

l is upholstering on cover D, forming the sofa seat.

J are the handles which form, when the device is converted intoits bed form, legs supporting the side of cover D.

The movable parts of the device, in addition to the cover D, comprise the combined back and base K, bed frame L, arms M, (attached to frame K and bed frame L, respectively, by pivots m), mattress N, head board O, foot board 0 side board 0 and springs P.

7c are handles on the combined back and base K. Springs P are attached at the ends thereof to receptacle B, as at p, and to side board as at 39 respectively. Said attachment to side board 0 is below rod Q, on which said board turns.

P are springs which are attached to the end boards '0, respectively, and to frame L. v Q

g are brackets, and said head and foot boards are respectively mounted on pivots Q .and brackets 9 Brackets g are secured on frame L. r, v

The manner in which the side board 0 is mounted causes springs P to yieldingly maintain said side board in a substantially vertical plane when the bed of the device is in a horizontal plane, as is illustrated in 'Fig. a, and to yieldingly maintain said side board at an angle to a horizontal plane, and pressing upward against the lower edge of the mattress N when said mattress is in a vertical plane, as is illustrated in Fig. 3. The. manner in which the head and foot boards 0, 0 are respectively mounted and attached to the springs p tends to yieldingly :ho'ld said boards in a horizontal plane,

when the bed is down, and when said boards are turned into a vertical plane, with said bed down, to hold them yieldingly in said vertical plane. This is effected by the carrying of the end of said springs which is attached to the said boards from one to the other side of the pivots q.

R are abutments on the head board O and footboard 0 respectively, and when said boards are in a vertical plane, with frame K and bed frame L in a horizontal plane, said abutments are in front of the front edge of the ends a, and said frames cannot be raised from a horizontal plane until said boards are turned from their vertical positions toward a horizontal position.

S are pivots which are secured to bed frame L, and t are castings which are secured to ends a of stationary frame A. Castings t are respectively provided with slots T and said pivots S rest in said slots to form the fulcrums on which the frame L may be turned from a vertical to a horizontal position and back. Y

When the combined back and base K is in a substantially vertical plane it forms the back of the sofa seat which is obtained by the upholstering I on cover D, and the front of said back and base is suitably finished for a sofa back. When said combined back and base K is in a horizontal plane it forms a base resting on the upper edges of the receptacle B and cover D, and at said time supports, (by means of arms M) the bed frame L.

It will be observed, by reference to Fig. 3, that when bed frame L is in a substantially vertical plane the combined back and base K is supported thereby, practically hanging therefrom on arms M, (the position of said arms being near a vertical plane), and when said back and base K and bed frame L are in a horizontal plane said arms are in substantially a vertical plane. This is effected by the said frame K being lowered on to the abutment E in the turning of frame L down on pivots S, and said abutment E forcing said frame K forward from the time when said frame rests on said abutments.

Pivots S are removably mounted in slots T of casting t to permit the removal of bed frame L from stationary frame A.

To convert the device from the sofa form illustrated in Fig. 1 to the bed form, the cover D is turned into the position which is illustrated in Fig. I, any bed clothing which is stored in receptacle B which is required to be used in making up the bed is removed therefrom; the frames K and L are turned down into substantially a horizontal plane, as is illustrated in said Fig. 4:, and the foot and head boards are turned into a substantially vertical plane. The bed is then made in the ordinary way of making beds.

To convert the device from the bed form to the sofa form, some or all of the bed clothing is removed therefrom, the foot and head boards are turned down into a substantially horizontal plane, the frames K and L are turned on pivots S into a substantially vertical plane, and (the desired bed clothing having been deposited in receptacle B), the cover D is closed on to said receptacle.

When the device is in the sofa form the cover D prevents frames K and L turning down from the position thereof which is illustrated in Fig. 1.

I claim 1. Ina sofa bed, a stationary frame, a bed pivotally mounted in said frame, arms pivotally mounted on said bed, a frame pivotally mounted on said arms, and abutments on said first named frame adapted to support said pivotally mounted frame and to change the relative position of said bed and pivotally mounted frame when said bed and last named frame are turned from a vertical to a horizontal position.
