To all whom it may concern: to the general exterior finish of the sofa. Be it known that I, JOHN A. ARToN, a 6 is a tie strip connecting the rear legs. citizen of the United States, residing at the 7 is a stationary cover for the top of the city of Chicago, in the county of Cook and back. 8 represents a seat with upholster- State of Illinois, have invented certain new ing 9. 10 represents a back with upholsterand useful Improvements in Sofa-Beds, of ing 11, and pivotally attached to theseat by which the following is a specification. a hinge 12 adjacent their proximate edges. y invention relates to the articles of The side members 13 of the primary or seat furniture sometimes known as sofa beds, section are secured to the normally under which may be converted by a change in the side of the seat and have projections 13, relation of their partsfrom a sofa into a which terminate in hinges 1 f. Tothe said ed, or from a bed into a sofa. These artihinges are attached the side n cn'ibers 15 of eles of furniture are so constructed that an the secondary bed section. Said members 15 upholstered back and seat are provided are connected to the back 10 b/y a flexible when the same is in use, as a sofa, but by shaekling device consisting of "themember a change of parts the elements of a bed, in- 17, pivoted to the seat at 18 and the memeluding the framework and springs, are disber 19 pivoted to the bed frame member 15 closed, together with necessary mattress and at 20. Said members are hin ed or pivoted other bedding. y invention comprises together at 21, and the member 19 is pro various features of construction by which vided with a hooked extension 22- for a purthe manufacture is simplified and cheap pose to be hereinafter described. A swing- 'ened, while at the same time the action mg link 25 has one end pivoted at 26 to the of the parts is more direct and positive. end piece 4. The other end of said link The transformation from one form to anmay be provided with a slot 25' and a pin other is light and easy, while the various 25 transverse to said slot, while the seat is parts are made to cooperate in such action. provided with a trunnion or pivot 27, upon t also consists in certain other separate dewhich it rests at the other end of said link vices and combinations which are hereinand within the slot. The niovement of the after fully set forth in the description and seat in either direction is limited by the claims. The principles of my invention are stops 29 and 30, between which the links 25 I illustrated in the drawings, in whichswing and with which they engage.

Figure 1 'shows a vertical sectlon, the end hen thus mounted, the seat will have t e same belng in their normal positions to which is determined by the said stops, albe used as a sofa; though in practice a slight variation or ig. 2 is a similar view showing the movflexibility of such movement is added by ing parts shifted and extended for use as a reason of the play of the trunnions 27 within e the slot 25, such play being limited by the Fig. 3 is a detailed top view of one end of transverse pin 25". This construction the same shown in Fig. 2. e v further provides means by which the seat Further describing my invention with with its attachments may be readily mount reference to the drawings, in which like ed upon or dismounted from the support characters of reference denote like parts mg frame. A stop 31 is attached to the in-' throughout: land 2 are respectively the ner face of the bed frame projecting infront andrear legs of a davenport frame. wardly toward the sea. A lug 32 se- 3 and 4. are the-arm and leg pieces by which cured to the end of the seat in such a p0sithe front and rear legs are connected." 5 is tion that when the same is advanced to its a facing strip connectingthe front legs: and limit of movement the said lug will'rest on' whichmay besuitably finished to correspond the said stop.

A similar lug 35 is secured to the end of the seat on the other side of the trunnion 27, in such a position that when the seat is inverted on said trunnion 27, the said lug will rest upon the stop 31, the scat being at its rearward point of movement as limited by step 30, but when the scat is pushed back within the limit of the slot 25', the

links 25 being in contact with stop 30, lug 35 will be disengaged from stop 31. That the relative positions of the pivot 20 and the stops 29, 30 and 31 may be made positive, I provide metallic. reinforcement plates 36 upon which the said pivots and stops are mounted. Said plates are secured to the inner faces of the pieces t which should be recessed to receive them.

W hen the seat is in its reversed position, and the bed members are extended a further security may be given by the projections 37 under the front and 37 under the back of the seat, which are received within suitable recesses in the upper edge of the facing strips.

Securely attached to the side bars 13 of the primary section of the bed frame are transversely extended projections 39, to .which are pivotally attached at -10 the side members of a bedding holder having the long arm 41 and the short arm 42. T ransvcrsely extended from the side bar 15 ot' the secondary bed section is a. projection 43 spaced a short. distance from the hinged connection 14. A tie bar 14 connects the two

extensions

40 and 43. A spring -15 has one end attached at, ll) to the long arm 41 of the bedding holder, while the other end of said spring is attached at 47 to the frame of the davenport. When the parts are in the positions shown in Figs. '1 and 2, the said spring should be under tension.

When it is desired to change the sofa into a'bed the seat is slightly lifted, sullicicntly to release the engagement of projection 37, and pushed backward upon the link 25, thereby disengaging the'stop 31 from the lug Upon taking hold of the upper part of the back and pulling forward, the action will be aided by the tension of spring 45, but as the back advances so that the spring passes its dead center the pull of the spring tends to extend lever 4l upon its pivot 40. thereby giving a thrust upon the tie rod ll against the extension 43., By the time the device has reached this point. in its movementthe natural hold of the operator will be on the secondary bed member adjacent to the the pull of the operator will join pull of the spring to extend the secondary bed section into alincmcnt with the primary hed section and in the relation to the back shown in Fig. 2.

Legs 48 are pivotally connected to the with the and turn thetop of the back. and

side bars 15. This preferably is by means of the upwardly extended member 49 secured thereto, whereby the point of attachment is raised above the side bar. The legs are provided with keyhole slots l9 and a. rivet or similar device, having a larger head and flattened body passes the slot in such a. manner that when the flattened body is in the narrowed portion of the slot the leg will be held at right angles to the side bar; while when the body of the rivetis in the eye of the slot the leg may be rotated in such body asa pivot. The legs are connected by a flexible brace 50, and are provided with an .outwardly projecting pin 51. The said leg is extended upward to form an arm, to which at 52 is pivoted one end of a retaining rail 53. The other end of said retaining rail is pivoted at 54 to one end of a link 55, the other end of which is pivotally connected to the side bar 15. This may be by means of the projection 43 extended transversely of the side bar for that purpose. The link 55 should be somewhat longer than the short arm of the leg 48, and the pivot 5* should be extended inwardly as shown at 5 1.

In folding the legs and closing the bed to form-the sofa the operator may take hold of the leg brace 50 at the same time slightly lifting on the ends of the secondary bed member to free the rivet in the key-hole slot -11), whereupon the legs are rotated. causing the same with the retaining rail and attachments. to assume the folded position shown in the dotted lines. In so doing the llcxible brace 50 permits the legs to be bent slightly toward each other and to engage under the projections 5-l in which position the natural stiffness of the brace will sceurely hold them. The brace is thus held upon the mattress and other bedding and forms a bedding holder to keep it securely in place during the time that it is not in use. A further upward and backward movement of the bed section causes the projection 37 to be disengaged and also to allow the seat to ride up on pin 27 in slot 25'. Lug 31 is thus lrced from stop 35 and the seat is permitted to turn on the trunnion .27. This movement is aided'by spring 45. The secondary bed members 15 turndownwardly on hinges ll, thereby causing arm 41 to fold over the primary bed member 3. When so l'oldcd the spring l5 tends to retard the natural turning tendency of the seat in its later movement. while in the final position it. aids to hold the bedding holder in place. Meanwhile the change in relation of side member 15 and back 10. as shown in Fig. 3, to the relation shown in Fig 1. causes the hook '22 to engage with thd projection 51 on leg 48. torming a t'urthe secure lock therefor. For further rigidity and security in the sofa use I provide a hook 56 on the under side of back 10, which is adapted to engage a stationary member 57 on the leg 2.
