LEAF-SUPPORT FOR SOFA-BEDS.

v srEoIFIcATIoN forming part of Letters Patent orm 142, date March 8, 1904.

Application mm September 17, 1902. Serial Nd. 128,703. (No model.)

To all whom it may concer m I Be it known that I',-OznLLO R. HUNT, a citizenof the United States, residing atKenosha', inthe county of Kenosh'a and State of Wise-om, sin, have invented a new and useful Improvement inLeaf-Supports for Sofa-Beds,.&c., of which the following is a specification. p I

My invention relates particularly to automatically-relea'sedleaf-supports for the rear leaves or'ba'cks of sofa-beds.

My primary object is :toprovide a leaf-sup port of this character of exceedingly simple and durable eonstructionand perfectly reliable in operatio Y In the accompanying drawings my invention-is illustrated'in' connection with a main [frame 'and'rear leaf Or -back of a sofa-bed,

though it will be obvious that the invention maybe applied to other articles of furniture of-a similarlnature. I In the. drawings, Figure 1. represents a broken view in side'elevationlof-a sofae-bed equipped with my improvement; .Fig. 2, a

brokenvertical section looking. at the inside of the end frame shown in Fig. 1; and Fig. 3, a broken plan section, taken as indicated at line ig. 2. I

. In'the preferred construction, A represents an end; standard of themain frameof a sofa bed;' B; "a wirefabric applied to the-seat and backofthe sofa-bed; C, a back or rear leaf of the sofa-bed; -D, a link pivotally connectedat on'e'end withthe back 0 and provided at.

. its free end with a stud D, and E a spring which serves in the locking. and releasing of thefree end of thelink. -It willbeunderstood.

that ordinarily eachend of the'sofa-pbed is pro-- vided with: this equipment. Assuming the;

portion 1a, fandjan upwardly and'forwardly extending portion a, which bears the stud D.

The end standard A'- is provided at" its horizontal member with a horizontal slot F, having aifenlargem'entor offset -F' at its front upper portion, afi'ordinga stationary lockingshoulder F corresponding with thestanding position 'of the leaf, the'front end of the slot the manner shown in Fig. 2, the rear-extremity of the spring being curved downwardly, preferably, as shown. Said spring is proserving as a; stationary locking-shoulder F, I corresponding with'the horizontal position ofv the leaf. The springE is connected by rivets d with-the horizontal member of-the end standard and has an inclined portion ii, which crosses the slot F- and its enlargement F in vided with a recess or slot d", located-opposite the front portion of the ofiset E; The stud -D Y is headed on its outerend and extends through the slot F and inwardlya shortj distanc'e beyond the outer edge 'of'theqspring E. Preferably the rear vertical member of the end'standard of the 'frame'is an "a le-ir'on and its inturned flange provide with a "slot f, serving as a guidefor the link D.

The operjation will be readily understood. In the standing position of the leaf the spring fE servestohold the front extremity of the link D in an elevated position, thereb causing the stud D toenga'ge .the shoul er F5; This prevents the back or leaf from dropping, as is evident. When it is desired to release theback. and lower it to the horizontal position, the back is moved forwardly somewhat 'froni' the position shown in Fig. 1 till the stud' D enters the slot of. the spring and per mits the link-to fall, whereupon the leaf is lowered, the stud during thismovement .rid-

ving upon the lower wall of the slot and fordving the spring up'wardlyuntil it is cleared by the stud; When the leaf reaches the horizontal position, the stud engages the rear end of the slot,' as indicated by dotted lines in Fig. 1. When the'leafis again raised to the standing position, the inner extremity'of the: i .90

stud D rides Iipon the upper surface of the extremity of the spring and is forced to th locking position shown in full lines.

While .my invention'was' devised for use in the situation illustrated-it is evident that it maybe employed in analogous situations. For instance, it may be employed to connect the back to the seat-frame of a sofa-bed, regardless of whether or not the seat-frame is lixed immovably to its supports or stamlards. Moreover, it will be understood that the arrangement of the parts may be altered or reversed witho'ut departure from my invention.

Changes in details of construction within the spirit of the appended claims may be made. Hence no undue limitation should be understood from the foregoing detailed description.

What I regard as new, and desire to secure by Letters Patent, is--- 1. In an article of the character described, the combination of a main frame provided with a guide and a stationary locking-shoulder, of a swinging leaf connected with said main frame, a link connected with said leaf and provided at its free end with a stud engaging said shoulder, a-nda yielding member w th, means for holding said stud in engagement with sald shoulder in one position of the leaf and permitting said stud to drop automatically and clear said shoulder in another position of the leaf, for the purpose set forth. I

' 2. In an article of the character described, the combination of a main frame provided with a guide and two locking-shoulders c0r-' responding with different positions of the back, of a swinging back connected with said mam frame, a'hnk connected w1th said back and provided at its free endwith a stud serving to engage/either one of said shoulders, according to the position of the back, and a yielding devicewith means for holding-said stud in engagement with one of said shoulders in one position of the leaf and permitting the link to drop automatically in another position of the leaf, so that the leaf can be moved so as to bring said stud into engagement with the other shoulder.

3. In an article of the character described, the combination of a main frame provided with a guide and a locking-shouldercorresp'onding with the standing position of the back and a locking-shoulderin' the rear of said first-named locking shoulder corresponding with the horizontal position of the hack, a

swinging back, a link connectedwith said back and provided at its free end with a stud engaging said guide, and a spring serving to hold said stud in engagement with the front locking-shoulder in the standing position ofsaid back and to permit said stud to drop out of engagement with said shoulder when said back is moved in front of its normal standing position, the guide then serving to direct the stud into engagementwith the rearshoulder, for the purpose set forth.

t. In an article of the character described, the combination of a main frame provided with a guide-slot having an offset at its upper front portion, whereby a locking-shoulder is presented at the rear portion of said oi'l'set and another locking-slumlder at the rear end of said slot, a swinging leaf, a link connected with said leaf and provided at its free end with a stud engaging said slot, a spring serving to direct said stud to said front lockingshoulder and hold it in engagement therewith, said spring having a recess, and a stud on said link riding on said spring until said recess is reached, for the purpose set forth.

5. In an article of the character described, the combination of a main frame provided with a guide-slot presenting two lockingshoulders corresponding with two positions of the swinging leaf, a swinging leaf connected with said' main frame, a linkconnected with said leaf and provided at its front end with a stud engaging-said slot, a spring secured atits front end to said main frame, and

provided with a recess, the rear portion of ,for the purpose set forth.

6. The combination of two frame members hinged-to swing with relation to eachother, one of said members having a guide and a locking-shoulder corresponding with the angular .position of the members withirelation to each other, a link carried bythe other memher and equipped with a locking-lug, and a yielding member with means for automatically forcing said lug into engagement with said shoulder in one relative positionof said first-named" members and permitting said lug to fall clear of said shoulder and effect an an tomatic release in another relative position of said first-named members, for the purpose set, forth.

7. The combination of two frame members hinged to swing with relation to each other, one of said frame members havinga guide and locking shouldena link connected with the other frame member and equipped at its free end with a stud engaging said guide, and a spring attached to the guide-equipped frame member and crossing said guide and having IIO a portion serving to lift said stud into en-'- gagement with said shoulder during one move ment of theswinging frame member and permit said stud to fall during a supplemental movement of the swinging frame member to pass beneath said spring during the return movement of the swinging frame member whereby an automatic locking and releasing of the swinging frame member is secured, for

the'purpose set forth.
