LEAF-SU PPORTI FOR SOFA-BEDS, 80C.

SPECIFICATION forming part of Letters Patent No. 740,567, dated October 6, 1903. Application filed December 13,1902. Serial No. 135,047. (No model.)

my pending application, Serial No. 123,703,"

filed October 22, 1902; and the primary object of the invention is to make provision whereby there shall be less liabilityof releasing the leaf by carrying the same too far in elevating it to the standing position. a v

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 may be applied to other articles of furniture of a similar nature and to positions of analogous nature in articles of furniture of the same general class. v

In the drawings,Figure 1 is a broken view,in side elevation, of a sofa-bed equippedwith my improvement; Fig. 2, a brokenvertical' section looking at the inside of the end frame shown in Fig. 1; Fig. 3, a broken plan section taken as indicated at line 3 of Fig. 2; Fig. 4,

of the sofa-bed; D, a link pivotally connected at one end with the back G and provided at its free end with a stud D, and E a spring which serves in the locking and releasing of the free end of the link. I

It will be understood that ordinarily each end of the sofa-bed is provided-with this equipment. Assuming the leaf 0 to be in the standing position shown in Fig. 1, the link D has pivotal connection with the leaf at a point 5o 12 some distance above the pivot b of the leaf.

which bears a stud D.

' horizontal position of the leaf.

The link has a substantially vertical portion 0, a forwardly-curved portion a, and an upwardly and forwardly extending portion 0 The end standard A is provided at its horizontal member with a horizontal slot F, having an enlargement or ofiset F at its front upper portion, affording a stationary locking-shoulder F corresponding with the standing positionof the leaf, the

front end of the slot serving as a stationary locking-shoulder F corresponding with the The spring E is preferably formed ofwireand is provided near one end with a loop or eye (1, by which it is secured to thehorizontal frame member {of the main frame by a rivet,the adjacent lend-of the 's'pringbearing beneath the horizontal flange of said frame member, as indicated in Fig. 2. The spring hasan inclined rear end portion at, which crosses the slot F in the manner shown in Fig. 2, and adjacent "to the portion dis a substantially horizontal portion d from which branches a lateral loop d located in a vertical plane and having its upper member connected with the portion d of the spring. The loop d affords a space (1 of slightly less diameter than the stud D'. The stud D extends throughthe guide-slot Fand stud beingiin engagement with the shoulder F Preferably the rear vertical member of the end standard of the frame is an angle- I iron and has its inturned flange provided withaslot f, serving as a guide for the link D.

G represents a stud or guide-pin depending from the horizontal flange of the angleiron forming the top of the end standard A and which aids in preventing displacement of the spring E.

Fig. 1 until the stud D is forced through the recess or space 01 of the loop d thereby automatically releasing the link and permitting it to fall upon the bottom of the slot F. When the leaf is lowered, the stud rides upon the lower'wall of said slot, thereby forcing the rear portion of the spring upwardly until it is cleared by the stud. When the leaf reaches the horizontal position, thestud engages the rear end of the slot, as indicated by dotted lines in Fig. 1. When the leaf is again raised to the standing position, the inner extremity of the stud D rides upon the upper surface of the extremity-of the spring, so that the outer extremity of the stud is forced again into locking engagement with the shoulder F Should the leaf 0 be accidentally moved too far in elevating it, thereby imparting to it an accidental supplemental movement beyond the standing position, the

stud will engage the loop d of the springwith a slight click, thereby preventing release. To effect a release, it is necessary to exert more forcethan ordinarily would come from a careless or accidental movement of in the situation illustrated, it is evident that v one of said members being provided with a guide and locking-shoulder, a link connected 1 it may be 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 fixed immovably to its supports or standards. Moreover, it will be understood that the arrangement of the parts may be altered or reversed Without departing from my invention.

Minor changes in details of construction within the spirit of the appended claims may be made. Hence no unduelimitation should be understood from the foregoing detailed description.

What I regard as new, and desire to secure by Letters Patent, is

l. The combination of two frame members hinged to swing with relation to each other,

with the other frame member and provided near its free end with means for engaging said guide and shoulder, and a yielding mom-- ber serving automatically to lock and release the free end of said link and havinga yielding stop for the link which serves to prevent accidental release under slight pressure and to permit release under greater pressure, for g the purpose'set forth. 1

2. The combination of two frame members hinged to swing with relation to each other, i one of said members having a guide and lock- 5 ing-shoulder, a link pivotally connected at one end with the other memberand provided at its free end with means for engaging said guide and shoulder and a spring on the guideequipped member having a portion crossing said guide and provided with a yielding stop, and a stud carried by said link and riding upon said spring during the movement of said link in one direction, said stop yielding to permit the passage of said stud under pressure and said stud passing beneath said spring during-the return movement of said link, for the purpose set forth.

3. The combination of two frame members hinged toswing with relation to each other, one of said members being equipped with a guide and locking-shoulder, a link connected at one end with the other member and provided at its free end with a stud for engaging said guide and shoulder, a stud on the opposite side of said link, and a spring having an inclined portion crossing said guide and a lateral loop adjacent thereto, said lastnamed stud riding upon said spring and pass- ;ing through said loop in one direction of movement of the link and passing beneath said spring in the other direction of movement of said link, for the purpose set forth.

4. The combination of two frame members hinged to swing with relation to each other, one of said members having an elongated guide lying in its own plane and provided at its upper portion with a locking-shoulder, a link pivotally connected with the other member and provided at its free end with a stud engaging said guide, a spring connected with the guide-equipped member and having an inclined portion crossing said guide, and a lateral loop adjacent to said inclined portion,

and a lateral stud upon said link of slightly greater diameter than said loop, said stud rid- 1 ing upon said spring and capable of being 1 forced through said loop in one direction of 1 movement of said leaf and passing beneath said spring during the opposite movement of said link, for the purpose set forth.

5. In means of the character described, the

@combination with a locking -link provided ;with a lateral stud, of a wire spring -having fan inclined portion lying in one plane and a lateral loop lying in a plane at substantially right angles to said first-named plane, through E which said stud may be forced, for the puripose set forth.

OZELLO R. HUNT.
