FOLDABLE TABLE,

Specification of Letters Patent.

Patented Nov. 14, 1916,

Application filed January 13, 1915. Serial No. 2,080.

To all whom it may concern Be it known that I, CARRIE M. CAVALINE, a resident of the United States, and a resident of Portland, county of Multnomah, State of Oregon, have invented a new and useful Improvement in Foldable Tables, of which the following is a specification.

My invention has for its object the pro viding of a foldable table, which may be folded into compact form so as to adapt the same for being conveniently carried about. To this end my table comprises a top, consisting of a plurality of detachable leaves, and the top is supported at each end by a trestle-like support, each support consisting of a top-rail mounted at each end on a pair of scissor-jointed legs, which may be fastened to said top-rail when the table is set up, and being adapted to be otherwise folded .lengthwise with. the top-rail; a pivoted strut connects oneof each pair of legs to the top rail, and a brace bar, pivoted to one of the companion legs, is adapted for locking the latter in extended position.

Other details of. construction and features of my foldable table are hereinafter more fully set forth:

In the accompanying drawings, Figure 1 is a side elevation of my table as it appears when set up; Fig. 2 is a top view of the table-top showing the latter as consisting of four leaves which are connected at their abuttingedgesby suitable locking means.

Fig. 3 is a transverse section on line 3-3; of Fig. 2. Fig. 4. is a view of the end side abutting portions of two adjacent leaves of the table-top, and particularly a means for lockin one with the other so as to maintain the ta le-top in level position as a whole.

Fig. 5 is a section taken vertical of Fig. 4:. Fig. 6 is a sectional detail showing the. tops of one pair of scissor-jointed legs, the top rail with which the tops of said legs are locked, the channel bar which is placed on as arranged in supporting position and in the rlght hand portion of this figure is illus trated the process of setting up and collapslng said legs; and Fig. 10 is a perspectlve sectional detail of the top rail of one of the trestle supports of my table, in connectlon with the channel bar which is placed on the top rail.

he top a, of my table is made of a plural1ty of leaves, a, detachably connected by sultable means at their abutting edges. The means which I find convenient to use comprise a latch-plate, b, and a latch-bar, c, the latter being made at its extremity with a bent over, or claw portion, 0".

In assembling the leaves, preferably the center leaves are first placed in abutment and locked together against lateral movement fromeach other. Such looking together is readily accomplished by simply restlng the inner edges of the two middle leaves .on the. trestle supportplacing such inner edges inabutment, meanwhile holding the outer edges of such leaves slightly elevated, then dropping the outer edges of the leaves on the trestle support, thelatch-bars, 0, will thus be engaged with the latchplates, Z). y I

The table top is supportedat its ends by two trestle-like supports of which one is perspectively shown in F ig. 9. Each support consists of a top rail, d, provided at itsendswith recessed .portions,.'e. At each end-of the rail, 61, are provided a pair of scissorointed supporting legs, consisting of members, f, 9, connected by a pivot, h. The

7 upper ends of the legs, 7, g, are recessed as at i, so as to provide supporting shoulders, and said recessed upper portions are inserted in the recesses, c,- of the rail, oi, as illustrated in Fig. 6. One of the legs,.f for example, is tied to the rail, 03, by a pivot- 1ng strut, 7, and to the leg 7" is furthermore pivoted a brace-bar, 7a,. the ,free end of which is adapted to be fastened to a studpin, Z. When the legs of the supporting trestle are set up, the latter will appear as shown in Figs. 1, 3 and 9. It will be noted that as soon as the legs havebeen set up in their proper position and the brace-bar, 7c, is fastened at its free end to the stud-pin, Z, the legs are firmly held in their set-up state. When the table is to be carried about, the brace-bar, k, is first unlatched and the legs may then be folded together in compact form so as to reduce the supporting trestles into a small bulk. It will be noted from Fig. 1, that the supporting trestles are arranged transversely under the table top. In order to stilfen the supporting trestles and provide a wider supporting surface than that afiorded by the top rails, d, I prefer to place on the latter a channel bar, m, which is fastened on the top-rail (Z, by means of a hook and stud, n. The channel bar, m, is provided with recesses, 0, at its sides, corresponding to the recesses, e, of the toprail, (Z, and like the latter, being adapted to receive the tops of the trestle legs, f, g. By reason of this construction, the top-rail, cl, need not be made of a length equal to the width of the top, but can be made of any convenient length, since the channel-bar, m, serves to support the outermost leaves of the table-top. Thechannelbar,- m, 'is provided at its extremities with hooks, 19, adapted to hold the sides of the table top against moving over the ends of the channel-bar, m, see Figs. 3 and 7 I claim:

' '1. Ina foldable table, the combination of a foldable trestle comprising a toprail and a'pa-ii'. of scissor-jointed legs at each end of the top-rail, a channel bar adapted to be reiiioyably' placed on said top-rail, the sides of'said channelbar being provided with recesses adapted to receive the upper ends of said scissor-jointed legs, and'means for fastenin'g said channel bar on the top-rail.

V 2. In a 'foldable table, the combination ofa foldable trestle comprising a top-rail and a pair of scissor-jointed legs at each end of the top-rail, said top-rail being pro vided'with recesses for receiving the upper ends of 'saidlegs, achannel-lbar adapted to he'removably placed on 'saidtop-rail, having its sides cut away in correspondence with said recesses of thetop-rail, and means for fastening the channel bar onthe top-rail.

3. In a foldable table, in combination witharemovable table top, trestle supports for the ends of the latter, each consisting of a top-rail, a pair of scissor-jointed legs for each end of the top-rail, means for removably connectingi'the upper ends of said scissor-jointed legs to said top-rail, a strut jointedly connected at one end to the top-rail and at the other to one of said pair of legs, means for securing said pair of legs in spread-apart position, a channel bar having its side-sent away in correspondence with said recesses of the toprail, means for fastening the channel-bar on the top-rail, and means for restraining the table-top against lateral movement on the channel bar when resting on the latter. 4. In a foldable table, in combination with a removable-tabletop, trestle supports for the ends of the latter, each consisting of a top-rail, a pair of scissor-jointed legs for each end of the top-rail, the top-rails being provided With recesses for receiving the upper ends of the legs, a strut jointedly connected at one end to the top-rail and at the other'to one of said pair of legs, means for securing said pair of legs .in' spread-apart positiorn'a channel-bar-having its sides cut away in correspondence with said recesses of thetop-raih'means for fastening the channel-bar on the t0p-rail, and means for restraining the table top against lateral movement on the channel-bar when resting on the latter. 7, i
