edges of the curved plate-6 are provided withv spaced apart hinge strips or4 knuckles 9, 9 clamped around the ypintles 10, 10. To
these' pintles` are .pivotally connected the which register With the alternately disposed hingepla'tes orfstrips are provided With the usual prongsl'g lto which the leaves are coiled springs 14 mounted upon the `pintles and provided With-fingers 15 'Which engage the. upper. face of the` corresponding hinge plates.
Describing now the locking mechanism for holding the prongs in either open or closed position, Within, the upper face of the curved supporting plate 6` is mounted a sliding'bar or arm 16,' the ends of which are provided with closedslots 17 riding in suitable conining studs or. guide screws 18. The outer end of the arm is provided with an upstanding handle 19 `whereby the-arm may be reoiprocatedacross'the face of the curved support-ingplate .As an important feature of construction the arm 16 is provided with ivedgelshaped cams 20 normally projecting through suitable apertures 21 formed'by cutting awfiiy n order'to positively lock or clamp the hinge plates in cl-osed position the cams are each provided With a locking lip or tongue 22 vvhi'ch project over the meeting edges of the hinge' plates'vvhen the latter are in closed position as 'shown at 23. The hinge plates are limited in their upward .movement by means of a downwardly curved closure plate Q41, the edges of. which are crimped over the hinge knuckles as shown at 25. This upper member 24 is slotted as shown at 26 at points .opposite`the prongs 13 in order that the lat- The` hinge lThe operation of the device is apparent I `from the above description. When 1t is desired to open the prongs to insert the leaves,
the arm 16 is drawn back until the cams pass out of theslots' 21 `whereupon the hinge plates will be obviously lifted and the prongs v swung apart. Tl1ey.will remain in this position `until the'arm 1G is again forced back to its original position whereupon the cam will reenter the slots and the hinge plates return to normal through the action of the springs. At the same time thelocking lips will ride `up over the meeting edges of the plates and positively lock the latter in closed position. j
