Specification of Letters Patent. [Aafli(lV Blau. 21, 1911. Application filed November f2.2,` 1910. lSerial No. 593,935. l i

To all whom 'it may concern: j

Be it known that I, KARL G. JoI-IANSON, a citizen of the United States, and a resident of Concord Junction, in the countyv of Mid dlesex and State of Massachusetts, have invented certain new and useful i Improvements in Folding Tables, of which the following is a Specification.

This invention aims to provide a brace and locking device for crosslegged two leaved top folding tables, the objects of which are, irst, stability when unfolded; and, second, compactness when folded. These objects are attained by the mechanism illustrated in the Figure 1 is a side :elevation of the table in folded position. Fig. 2 is a section (en-A larged) on line 4(2. 2.) of Fig. 4, the top, top stays and leg Supports being omitted. Fig. 3 is a section (enlarged) on line (1. 1.) of Fig. l, of one endof the table. Fig. 4 shows the end elevation of the table inunfoldecl position. y Y

Each pair of leg supports (4) are vconnected near the center by a split headed bolt (7), two jointed bars (5) each having their -lower ends pivotally connectedto said bolt heads while the upper endsl have a similar connection to a head piece (12) at'a' point (17) the latter being grooved to, receive the upper sect-ion of vsaid, bars when the table is unfolded, as best shown in Fig. 4. Two sleeved rods (8) are each provided with a lock (3) the lat-ter being adapted to swing to one side from the pressure by the brace bars on its outer slanting face, .into the cavity (6) Fig. 2 containing a spring (10) by which said lock' is forced back into its loclcing position when the bars have entered the groove (9). The rods lare projected outside the face of the to stays (14) having their ends Hattened an bent downward whereby the locks can be operated when the table is folded. j The outside projections of the rods and also the springs can be omitted, tlie locks being then actuated'by gravity. The sleeve (153) Vtogether with the rod form apivot forboth the head piece and the plates (15) the latter being secured by suitable means toit'llije.

lane as shown accompanying drawing in flocked thereto.

2. In a folding table, a top formed in two while the bent leg supports increase the sta-4 l bility and provide space yforthe top stays when the table is folded so that all'the connecting points between the top stays and leg supports, between the top stays themselves and those between theleg supports,- where the latter cross each other, center in one in Fig. 1 and Fig. 3.

1. In a folding table comprising a top ,formed in two sections, stays atn the ends of each section, the stays ofthe one section being pivoted to those ofthe other section, two

pairs of legs pivpted together intermediate their ends, the upper ends of each pair being ypivoted to the st-ays, a head piece adjacent the top sections, folding brace members, each comprising hinged sections, the .upper sections pivoted to the head piece on a common pivot, the lower sections pivotally connected to the legs adjacent the pivotal point thereof and locking means associated with the head piece whereby upon unfoldingthe table the uppersections of the braces are folded adjacent the head piece and automatically sect-ions, stays at the ends of each section, the stays of the onesection being pivoted to those of the other section, a head 'piece i mounted between the stays central to theirf pivot points, folding brace members, each comprising hinged sections, the lower sections pivotally connected to the leg supports adjacent the pivotal points thereof, the up'.- per` sections pivoted to the head'piece on a SOv common pivot, a recessin said head piece extending iny a transverse direction to the folding planes of the legs and serving asa guide for' the,1 :brace members and automatically 'disposedlocking,means at each end of said recess whereby upon unfolding the 'table the .braces are extended transversely tothe leg supports and locked in position. r

3. In a folding table, pivoted top sections,

stay members near the endsof the sections,

ypivotal connections betweenuthe staym`em-.
