SOFA-BED.

SPECIFICATION forming part of Letters Patent N 0. 702,958, dated June 24, 1902.

Application filed July 24,1901. Serial No. 69,505. (No model.)

To Z7 whom it may concern:

Be it known that I, HERBERT C. Jones, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Sofa-Beds, of which the following is a specification.

The object of this invention is the production of an improved hinge-joint connection between the seat and the back of a sofa-bed, by means of which said parts may be locked together to permit the raising and the lowering of the back by the movement ofthe seat.

In the accompanying drawings, Figure 1 is a transverse vertical section through the body of a sofa-bed, showing my improved hinge-joint between the seat and the back, also in dotted lines the position of the back when it is lowered to a horizontal position. Fig. 2 is a detail perspective view showing the parts of the hinge-joint in the same position that they are shown to occupy in the next preceding figure. Fig. 3 is a side elevation of the hinge-joint after an upward movement of the seat.

Like letters of reference indicate corresponding parts throughout the several views.

A is the supporting-frame of a sofa-bed; A, the seat; A the back, and A a pocket, open at the top, one ofwhich pockets is secured by any suitable means to the inner side of each end of the supporting-frame A. The seat A comprises the end pieces A", one of which pieces is situated at each end of said seat. The arm A is fixed to the outer face of each of the end pieces A and extends rearwardly from the seat A. Near its outer end this arm is provided with a trunnion A adapted to lie within the pocket A forming a pivotal connection between the seat A and the frame A. The pocket A being open at its top permits of the withdrawal of the seat and back bodily from the supporting-frame A, which is desirable in cleaning or repairing the bed. A is the end piece at one end of the back A To the inner face of the end piece A I secure the member 13, and to its corresponding end piece A of the back A I attach the memher B which members I3 and I are connected by the rivet B and form a hinge-joint connection between the seat and the back. One of these connections is provided between each end of the seat and back. The member B is provided with a guard or hasp B, with a fixed stud B and with a gravity-pawl B, pivotally mounted on said member B by means of its pivotal stud B A locking-bar O is pivoted near one of its ends to the hinge member 13 by the stud O. The opposite end of this bar lies within the guard or hasp B and is provided near said end with a pocket 0 adapted to engage the fixed stud of said hinge member B and outward from this pocket with two teeth C and C for engaging the point of the gravity-pawl B. Then the lockingbar lies with its pocket in engagement with the fixed stud B the back A and the seat A are locked from turning outward on their connecting hinge joint. Therefore raising the seat will lower the back.

lVhen the parts are in the position indicated in Figs. 1 and 2, to lower the back A into a horizontal position the seat A is first raised into a vertical position. This turns the back A downward into the desired position. The seat is then raised a little beyond its vertical position, withdrawing the pocket 0 of the pivoted bar 0 from -t he fixed stud B and permitting the gravity-pawl B todrop into engagement with the tooth C of the bar. The seat may now be lowered into its normal position, the pawl B raising the free end of the bar 0 from engagement with the fixed stud B, permitting said bar to slide upon said stud as the seat assumes its normal position, as indicated in dotted lines in Fig. l.

IVhen it is desirable to raise the back to an upright position, the seat is .turned upon its pivotal trunnions A upward until the lockingbar 0 is drawn rearward in the hasp Eta sufficient distance to permit the fixed stud B to enter the pocket 0 in said locking-bar. The gravity-pawl will then lie in engagement with the tooth C of said bar. Upon returning the seat to its normal position the back A will be raised. If when the seat is in a vertical position it is pushed a little farther over toward the back, the locking-bar O is drawn outward, so that the gravity-pawl B engages the tooth C of said bar, after which the seat may be turned downward to its horizontal position without disturbing the back.

I claim as my invention 1. In a sofa-bed, in combination, a supporting-frame; a seat; a back; a hinge-joint between the seat and the back; a looking-bar extending between the members of said hingejoint, said bar being pivoted to one of said members and being adapted at its other end to engage a stud fixed with relation to the other member and having a tooth adapted to engage a pawl pivoted to said other member; and said fixed stud and said pawl.

2. In a sofa-bed, in combination, a supporting-frame; a seat; a back; a trunnion carried by the seat; a pocket supported by the frame for receiving said trunnion; a hinge-joint between the seat and the back; a looking-bar extending between the members of said hingejoint, said bar being pivoted to one of said members, and being adapted at its other end to engage a stud fixed with relation to the other member, and having teeth adapted to engage a pawl pivoted to said other member; and said stud and said pawl.
