as indicated in Fig. 1, the separation of the top sections while the pedestal .sections remain engaged with each other, being limited by stop bolts 19 on the guides 14, which engage complemental stop shoulders on the slides 17 atlixed to the top sections. Provision is thus made for a minimum extension of the table, the arrangement being preferably such that when the top sections Aare separated to the maximum extent permitted while the pedestal sections are locked f together, space is afforded suflicient to pereach support as here shown, including end construct-ion.

shown'in Fig. 2.

VTwo independent locking mechanisms are provided, one for detachably locking the pedestahsections together and the other for detachably locking the'top sections together. These mechanisms mayv be 4of any suitable specific locking devices here shown are set forth and claimed in another application filed concurrently herewith by Edgar L. Marston, and the same are noty therefore specifically claimed by me.

The pedestal locking mechanism here shown includes a rock-shaft 23 journaled in a bearing'24 affixed to one of the edestal sections 12, a disk 25afiixed to sai rock-shaft and having astud 26Iwhich is eccentric to the shaft 23, a hook 27 pivoted to swing on the, stud 26, and a loop dicated bythe arrow in Fig.l 5, the hook is4 firstf'moved backwardly from. its bearing on `,the floop 28, and is then swung laterally out oreye 28 affixed to. the opposite pedestal section in position, toy

drawing tlilpedestal sections together, andA holding them in close contact with each other. The rock-shaft 23 extends through the upper end` of the pedestal, and is provided with a hand wheel 29, by which it may be rotated, access to the hand Wheel being provided. by separating the top sections 16..

The mechanism here shown for detachably ,locking the top sections together includesa loop or eye 30 attached to the under side of one of the top sections 16, a bell-crank lever 31 having a slot 32 through which passes a fulcrum stud 33 attached to the opposite top A section 16, the lever 31 being adapted both to swing and to move endwise on the fulcrum stud, and provided v with a hook 34 adapted to engage the loop-30, an operating lever 35 fulcrumed at 3.6.to an ear aiiixe to the under side of the top section 16 which supports 4the lever 31,.and a connecting'rod 37 engraved at 38 with one arm of the lever 31, andzliaving at its opposite end a clip 39 which is pivoted at 40 to the lever 35, the arrangement being such vthat when the lever 35 is in the position shown in Figs. 3 and 6.

thehook 34 ofthe lever is within the loop'l 30, and presses against one end of the sa1d` loop with sufficient force to rdraw and hold the meet-ing edges of the top sections-1G` closely together. lVhen the lever 35 is swuiw downwardly from the .position shown in F 1g. 3, the bell-cran'ltlever 31 is first moved endwise to remove the hook 34 from its bearing on the loop 30, ,and 1s then swung laterally, wlthdrawing the l hook from the loop. 'The change of 'position of the lever 35 to the position shown in F ig. causes the hook 34 to first swing into the loop, and then to move endwise and exert sufficient pressure on theloop-'to'force the top sections 16 firmly together.

It .will be seen from the foregoingthat provision is made for partly extendin the table top without separatingl the pe estal sections, and for giving the ta le top a maximum extension by the separation of the pedestal sections. y

Each of the stop bolts 19 and 22 is yieldingly held in its operative position by a spring42, and is provided with a shank or handle 43 whereby it may be manually retracted from engagement with the correspondin shoulder to 'permit the separation lof `the s ides 17 from the guide members 14 and of the end members 20 of the telescopic supports from the intermediate members 21. Provision is thus made forv entirely separating the slides 17 from the guidemembers K' 14 and the end members 20- from' the inter:

' provided with beveled faces arranged to re- 'permanent top sections, or

leaves,

tract the bolts when the pedestal sections and top sections are moved toward each other to contract the table. The said beveled faces .and stop shoulders, against which the bolts abut, form recesses into which the bolts are projected by their spri11gs \vhen the pedestal sections and the topv sections reach their maximum extension. A further extension to disconnect the pedestal sections from each other land the top sections from each other and from the pedestal sections,y is permitted by retracting thebolts 19 and 2Q.

It will be seen that tivo sets of telescopic `supports are provided, the supports of one* set being composed of the uide members 14 and slides `17, and supportingr the permanent sections of the table top, Whilethe supports of the other set are composed of the end members 20 and intermediate members 21, and support the removable leaves when the pedestal sections and their attached slide members 1'1 are respectively separated. It will also be seen that each support has complemental stops which normally limit the extension of the support, and are separable to permit the entire separation of its inembers by a continuation of the extension of the support. A top support of this character is believed to be` broadly new in an extension table, and it is therefore my intention to' be understood as claiming broadly a support or a set of supports thus characterized, Whether employed for supporting the the removable or both the permanent sections and leaves.` I also believe myself 4to be the first to provide one of the members of the support with a fixed stop shoulder and a beveled face adjacent thereto, and another mem- `-ber With a spring-pressed bolt adapted to be retracted by said face when the support is contracted, and to be manually retracted to permit the separation of the members.

By providing the knock-down construe-- tion herein described, I produce a pedestalextension dining table in Which it is possible to remove Ythe sections comprising` one top and to substitute therefor another top of different diameter or design, this being accomplished Without the removal of such perma- Y nent fastenings as screws or the like. Vhile I have described the manually-operable deviceswhich normally limit the' separating movement of the top sections as being of the nature of spring-pressed bolts, neverthelessl I do not desire to limit myself thereto as their equivalents may be substituted therefor. Moreover various other changes of similar character may be made Without departing from the spirit and scope of the invention. V

I do not herein specifically -claim the knock-down extension dining table illustrated. described and claimed in my application, Serial No. 540,992. filedv January 31,
