'NEW JERSEY, ASSIGNOR I TO FERGUSON BROTHERS MANUFAGTURIN G COMPANY, HOBOKEN, NEW JERSEY, A 'GOR PORA- FOLDING TABLE Application filed November -10, 1931; Serial No; 574379.

. Theobjeot of my invention is to provide,

in a folding table, a novel spring means for ensuring the locking coaction of the foldlng braces with their folding legs when the legs are unfolded; saidgspring means also serving, by their pressure on theleg braces, to frictionally hold the legs in their folded position.

; Myinvention generally comprises a keeper pivoted on each of the folding legs, afolding brace slidablein thekeeper and a spring located at the keeperand slidable on the brace, said spring ensuring the locking-coaction of the brace and keeper when the leg and brace are unfolded. v

My invention specifically comprises a keeper havinga bow spring for the above purpose, said spring slidably engaging the folding brace upon opposite sidesof the keeper. In one form of my invention {the keeper and spring are separable, means being provided for positioning, the spring against longitudinal displacement in the keeper and against lateral displacement on the brace. In another form of my invention the keeper and spring are formed integral, means being provided for positioning the spring against lateral displacement on the brace.

A practical-embodiment of my invention is represented in the accompanying drawingin which:

Fig. 1 represents a detail side elevation at one corner of the table with the legs shown in their unfolded position; v

Fig. 2 represents a similar view taken at right angles to Fig. 1;

Fig. 3 represents a detail longitudinal vertical section taken in the plane of the line IIIIII of Fig. 4, looking in the direction of the arrows;

Fig. 4 represents a detail inverted plan view of the table with its legs in their folded position;

Fig. 5 represents a detail longitudinal vertical section showing the spring pressed sliding connection between the foldingleg brace and keeper when the parts are in an intermediate position;

Fig. 6 represents a front view of the bow spring for: exerting locking pressure on the folding leg brace;

Fig. 7 represents a rear view of the same Fig. 8 represents a side view of a modified form in which the keeper and spring are formed in one piece; and Fig. 9 represents a rear view of the same.

I The table top is denoted by land its pe rip'heral frame by 2. I, Each ofthe folding legs 3 is shown as provided with a laterally 6() extended hub 4, pivotally mounted: between the frame 2 and aplate 5.

the leg. V One end of a folding leg brace 7 ispivoted at 8 to the inner fa e of one of the top frame sides, which folding brace has a notch 9 near its outer end arranged to coact with a keeper and brace are moved to theirfolded and una folded positions.

A stop pin 12 is located on the folding brace 7 in position to limit the unfolding movement of the leg. i

' Spring means are provided at the keeper 11 for ensuring the coaction of the notch 9 in the folding leg brace 7 with the pivot pin 10 on the leg when the leg is unfolded, to lock the legand bracein their unfolded position. I In the form shown in F igs. 1 to 7 inclusive, this spring means is shown as a bow spring 13, separate from the keeper, said spring slidably engaging the folding brace 7 upon opposite sides of the keeper, the ends of the spring having depending ears 14 for positioning the spring on the brace againstlat- 9, the keeper 16 is provided with integral oppo-- sitely projecting branches 17 forming a bow .109 Y v A rigid d agonal brace 6 is shown as leading from the hub to g spring. These branches are provided with depending ears 18 for positioning the free ends of the branches on the folding brace 7 against lateral displacement with respect thereto. 7

From the above description it will be seen that I have provided efficient means for ensuring the locking coaction of the folding leg vention, and hence I What I claim is:

and its folding brace when the leg reaches its unfolded position.-- To release theqleg and brace to permit them to be folded, the brace may be manually-lifted against the tension of the spring sufficiently to release its notch 9 from engagement with the keeper pivotlpin 10. The tension of the spring shouldbe sufficient to retain the leg and brace in their folded positions,against unintentional movement. i i It is evident that various changes may be resorted to inthe' constructiomform andarrangementof the several parts without departing from the spirit and scope of my inited. to the "particular embodiment herein shown and described, buti 1. Ina table,afolding leg, a keeper there on, a folding brace slidable in the keeper and arranged to coact therewith a lock the leg in its unfolded positiomand a spring at the keeper, slidably engaging the brace and tend ing to force the brace into its locking position, said springbeing provided with means to prevent its lateral displacement on the brace. i 1 2. In a-table, a folding leg, a keeperthereon, a folding brace slidab le inthe keeper and dornot intend to be limarranged to coact therewith to lock the leg in its unfolded position, and a bow spring at the keeper, slidably engaging the brace upon opposite sides of the keeper and tending to force the brace into its locking position, said spring being provided with means to prevent its lateral displacement on the brace.

3. I11 a table, a folding leg, a keeper pivotally mounted thereon, a folding brace slidable in thekeeper and provided with a notch arranged to coact With the keeper pivot to lock the leg in its unfolded position, and a bow spring positioned in the keeper, slidably engaging the brace upon opposite sides of thekeeper and tending to force the brace into itsjlocking position, said spring being pro vided with shoulders to prevent its longitudi nal displacement in the keeper and also provided withea-rs overlapping the brace to preventits'lateral displacement thereon;
