Specification of Letters Patent.

Application filed November 14,1904. Serial No. 282,636.

Patented May 15, 1906.

T0 11 7] whom it may concern:

Be it known that I, J ULrUs SENG, a citizen of the United States, residing at Chicago,

in the county of Cook and State of Illinois,

have invented a Sofa-Bed, of which the following is a specification.

This invention relates to improvements in sofa-beds, and particularly to that class of sofa-beds wherein there are comprised movable seat and back sections hinged together at their meeting ends through the medium of a locking-hinge, the back-section being operated through a manipulation of the seatsection.

The objects of the present invention are to provide a cheap and simple construction of sofa-bed which when the same is withdrawn from the wall a slight distance may by an easy and convenient manipulation of the seat-section cause the latter to be advanced and the back-section simultaneousl ad vanced and lowered into a plane wit said seat-section, wherebythe two coact or combine to constitute a comfortable bed, and, furthermore, by a reverse manipulation of said seat-section the same will be retracted within the frame and the back-section simultaneously retracted and relevated to its normal position, whereby the article is reconverted into an ordinary sofa.

Various other ob'ects and advantages of the invention will ereinafter appear, and the novel features thereof will e particularly ointed out in the appended cla1ms.

Re erring to the drawings, Figure 1 1s a transverse vertical sectional view of a sofabed embodying my improvements, the same being illustrated in bed form. Fig. 2 is a similar view with the back-section lowered and advanced as in Fig. 1, the seat-section being elevated, so as to disengage the same from locking engagement with the back-section prior to a lowering of said seat-section. Fig. 3 is a similar view with the article shown in sofa form. Fig. 4 is a 'detail in elevation of the preferred form of locking-hingeemployed between the seat and back sections, the hinge being shown in the position it Wlll assume when the parts are in the relative position shown in Fig. 2 of the drawings. Figs. 5, 6, 7, and 8 are details hereinafter described.

Like numerals of reference indicate like parts throughout the drawings.

The sofa-frame comprises the usual opposite end ieces 1 1, the two being securely connecte by the transverse base 2. This base may comprise the usual box or receptacle 3,. such arrangement not formingv any part of my present invention.

Mounted removably upon the transverse base 2 is a seat-section 4, and between the two end pieces and in the present instance wholly independent thereof, so as to be free to move therebetween, is the back-section 5. At their opposite meeting corners the two sections, the seat and the back, are connected, in this instance by a locking-hinge 6, the details of which I will now proceed to describe.

The locking-hinge 6 shown is the preferred form, though other styles of hinges may be substituted. In the present instance, how ever, it comprises the opposite leaves 7 and 8, designed in the usual manner to be secured, respectively, to the end rails of the seat and back sections. Each of these leaves has formed at its lower inner corner one member 9 of an ordinary. hinge eye. These two hinge-e e members overlap in the usual manner an are pivotally connected by means of a transverse pintle 10.

' A stud 11 preferably headed, projects from the face of the hinge member-or leaf 8, near the outer lower corner thereof, and loosely pivoted at a corresponding point on the face of the opposite hinge member or leaf 7, as at 12, is a stud-engaging gravity-latch 13. This latch lies across the faces of the two hingeleaves 7 and 8 and near its free end is provided on its under side with a recess 14, designed to engage the headed stud 11 under certain conditions. The recess terminates at its inner or front end in a shoulder 15 and at its upper or outer end in a shoulder 15. The recess being slightl longer than the diame ter of the shank'of t e stud, it will be obvious that the two leaves are capable of some little pivotal movement or se aration before either of the recesses is broug it in contact with the shank of the stud and a locking of the two leaves effected.

Pivoted to the face of the gravity-latch 13, as at 16, immediately in rear and slightly above the recess 14 of said latch, is a small gravity-paw] 17, having at its free end a recessed shoulder 18 and at the opposite side of its pivot-point a stop-shoulder 19,'designed to abut against a stop-pin 20, whereby the movement of the pawl 18 limited in both d1- rections. The pawl 17 at its free and lies across the recess 14 of thelatch, and its shoulder 18 is slightly beyond the shoulder of the latch and, like the latter shoulder, is designed under certain conditions to engage with the headed stud 11.

At the outer side of the hinge there is secured in' a manner hereinafter described or otherwise, as preferred, and to the end rail of the back section 5 a bracket 21. This bracket is provided in the present instance with a right-angular lug 21 for engaging the side rail of the back-section and with a screw-receiving opening 21*, through which a screw may be inserted into said end rail. Its opposite branches project out each side of the pintle 10 of the hinge, and to its front branch there is loosely pivoted, as at 22, the upper end of a laterally-swinging supporting-rod 23, the lower end of which is pivotally connected to a stud-plate 24, secured to the lower crossrail of the end piece 1 in advance'of the meeting ends of the front and back sectionswhen said sections are arranged in sofa form. To the opposite or rear branch of the bracket 21 there is pivoted, as at 25, the upper end of a shorter companion governing-rod 26, the

lower end of which is pivotally connected by a stud-plate 27 to the end piece 1. These rods are of course duplicated at each side of the sofa-bed.

In operation taking, for example, the article shown in Fig. 3 in order to convert the same to a bed it is first necessary to withdraw the article a short distance from the wall, against which such articles are usually located. Having done this, the operator grasps the seat at the front and draws the same forward and upward, thus raising the free end to the position shown in Fig. 2. B reason of this operation it will be seen that the seat and back are elevated aboveandlowered in advance of their former positions upon the base 3. This elevating and advancement of the seat and back is accomplished by the governing-rods 26 operating in conjunction. with the laterally-swinging supporting-rods 23, for, as will be apparent, the former rods being eccentrically pivoted with relation to the rods 23 will cause the latter to swingforward as the seat is elevated, whereby the seat and back sections are caused to clear the base in their turning movement. When the parts have reached this position, they are as shown inFig. 2. The operator continues the backward movement of the seat for a short distance, or until the shoul- .ders18 of the pawls 17 have engaged with the shanks of the studs 11, after which it is simply necessary to lower the seat to 'theposition shown in Fig. 1, the pawls11'7, it belng understood, operating in the usual manner,

of the stud-11, after which the seat passing 7 beyond the pawl the latch 13 will be released, and for thebalance of the movement the lower curved edge of the latch 13 will loosely over the stud 1 1;

Toreturn the parts to the position of a sofa, the seat-section 4 is again elevated until the inner shoulder 15 of the latch 13 engages with the stud 11, after'which it is simply necessary to lower the seat-section and at the same time gently push the seat-section backward. The rods 23 and 26 coacting with these two sections will retract both the seat and back section at the same time the seatsection is lowered and the back section elevated, thus bringing the parts to the position shown in Fig. 3.

It will be observed that I have obviated in the construction of the end pieces 1 the usual guides employed for guiding the back-section 1n its movements, thus not only greatly simplifying the structure of the article as a whole and relatively cheapening the same, but also causing the article to be more sightly in that all the mechanism is hidden from View. It furthermore obviates the frictional contact between the end pieces and the back-section, rendering the movement of the latter noiseless and easier. The lower ends of the laterride ally-swinging supporting-rods being ivoted reached a vertical position, and when this has been accomplished by reason of the presence of the rear governing-rods the two sections are balanced and may be moved in either direction with little effort, so that the remainder of the operationthat is, of advancing and lowering the .back and simultaneously advancing and elevating the seat is practically automatically accomplished.

Of course other forms of locking-hinges may be substituted for the construction of hinge herein shown and described without departing from the spirit of my invention, and, in fact, other details may be altered all within the scope of my claims.

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

1. The combination in a sofa-bed, of 0pposite end pieces, a transverse connectingbase, a seat and a back section mounted between the end pieces and independent of the same, a locking-hinge connecting the seat and back sections at their meeting corners, a bracket arranged at each end of and secured to the back-section and extending at ceases opposite end pieces, the transverse connectlng-base, a seat-section mounted movably on the latter, a back-section arranged between the end ieces, opposite locking-hinges connecting t e two sections, and oppositely-inclined sus ension-rods upon whlch said sections are esigned to move, said rods having their lower ends connected to the framework at opposite sides of the meeting edges of the front and back sections.

3. The combination, in'a sofa-bed, of oposite end pieces, a transverse connectingase, seat and'back sections, opposite lockthe two sections at their meeting edges, ont and rear supporting-rods, theformer being longer than the latter, means for connecting said rods at their lower ends to the framework of the article, and means for connecting the upper ends of the rods to the seat and back sections at opposite sides of the pintles of said lockinges. 4. In a sofa-bed, the combination, of the opposite end pieces, the transverse connecting-base, the seat and back sections indcpendently movable between the end pieces, the opposite locking-hinges connecting the meeting ends of the said sections, brackets secured to the back-section and overlappin the front section at the meeting edges of sai sections, suspension-rods connected to the opposite ends of said brackets, and means for connecting said rods at their lower ends to the framework.

5. In a sofa-bed, the combination, of the opposite end pieces 1, the transverse base connecting the two, the seat-section t and back-section 5 independent of the end pieces, the opposite locking-hinges connecting the sections 4 and 5 at their meeting ed es, the opposite angular brackets 21 secured to the end rails of the back-section and overlapping the end rails of the seat-section, and the suspension-rods 23 and26 pivotally connected at their upper ends to the front and rear ends of the brackets and at their lower ends pivotally connected to the framework, as at 24 and 27.

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