.Applicationl filed .T une .15,

Be it known that I, JOSEPH HLozEn, a citizen of the Republic of Czechoslovakia, residing at Cleveland, in the county of Cuya` hoga and State of Ohio, have invented cera tain new yand usefuly Improvements inEXtension Tables, of which the following is a l specification, reference being had to the ac- 15, 'i extendedto its full length or -collapsed with companying drawings.

This invention relates to ticularly'to extension tables.

The general object of the invention is to tables, and par- *provide an extension table which is relatively simple in construction, which may be cheaply made, and which may be relatively but a minimum of effort. l

A further object is to provide. a construction of this character embodyingva main table top with a supporting frame and legs or other supports,` and a plurality of sets of leaves, one for each side of the table, `normally housedl beneath the main table top but adapted to be shifted outward to extend the table, said leaves when extended lying n flush with the main table top; and provide main table top may bel raisedv in order to permit the superimposed leaves to be shiftu ed beneath the main table top.

Other objects have to do with the details of construction and arrangement of parts as will hereinafter more fully appear.

My invention `is illustrated in the accompanying drawings, wherein Figure 1 is a side elevation of the table folded; I

Figure2 is a fragmentary longitudinal sectional view of thel table expanded and showing in dotted lines the positionsv taken by lthe leaves 15 and 22 whenvthe table is being expanded; l

Figure 3 is an under side plan lview of the table folded.; y

Figure'4 isa cross sectional view on the linee-lof Figure;

`The vrocking movement is, of course,-aper`` y yflaring characterl I 19,21.` Serial No. 477,790.

Figure 5 lis a perspective viewof one vlof" i the hinges between` the` slideJ`v 20.. and the leaf 22; t

' Figure .6 is a side elevationlofth'e operatffo 2 'i Referring to ythese drawings,v ldesig-y fl nates two'parallel side supporting sills for g beams which areconnected by a 'transverself horizontal frame member 11 and whichfmayff C be supported in'anysuitablemanner but'isf` j. illustrated "as'supportedl by the'fourlegs 12,' Y

and disposed at the middle thereof'is a trans# i verse supporting member 13 which is pref.v erably madein. two sections and is of woody?, if f and which is formedwitli downwardly flaring sockets 141 in its upper surface.. ``Rest-` ing upon this member 13 is theymaintable-,if` top 15 which is provided atopposite l ends 5,

with downwardly projecting pins.1'`eXtendv ing intolthe sockets 1li. These pins are pre-k f erably ofy iron. This connection ofthe table y .top to the supporting member 1 3 permits 'the table top 15 to beraised orfloweredtola certain extent vand to.l be rocked; upon av fulcrum2 as will be later described. The pins 16 ymay be so'formedl as to prevent the'` mit its elevation' land rocking movement.

mitted by the downwardly of the *sockets 14.

Disposed below the'und'gfaceofthesupw .porting` member l13,andextending in Parana the two upwardlyv andyoutwardly inclined sections17 and '18, these guide sections being f' l, y' .i

glued to the frame member 11 andextending` upward therefrom. lhc-isefslide sectionsl'ggand 18 may be formed vwith'dAovev-tailed grooves on their oppositey faces 19. 'These sections 17 ,and 18 upon their opp'osite'faces i may also be formed with dove-'tailed'tongues I ifdesired.` l' have illustrated grooves for this purpose but T .do not'wish to 'be vlimited to the particular shape-offthegrooves .19.v

Coacting with each`of the guides 17 `and` therefore formedv with dove-.tailed tongues. y

withfthe guides 17 and 18 and vwhichlar'e oov f slidingly engaging the dove-tailedgrooves i9. each disposed'on one-side of the -guidesecthese guide `sections 17 and.v 18 are disposedV There .aregtwo of. these lmembers 20 tions 17 an`d18, and onl-the opposite side of 110..

two other sections 20kal correspondingftojtha sections 20. Coacting with the sections20- land havingsliding engagement therewith by lmeans of tongues andl grooves aref` the slide sections 21, and engaging with theslide sections 20a are the slide sections 212%.` lt will be understood, of course, that the slide sections 2O and 2l arey extended in one direction when the table is pulled out, while the slideA sections20L and 2la are'extended in the opposite direction. l

y v(lla-rried by the slide sections20 on one yside ot the tableis a leaf 22, which leaf-has l attached to its under side at its butt end the `downwardly extending hinge member 23 .whichI is disposed between ears 24- having horizontal upper edges, these ears 2d# being mounted upon a'plate 25 which is attached to the-upper lace oit' the corresponding slide section soinewhat inward troni the extremity tions 20. i I

Y Y, the slide sections 20TL by a like hinge conneci slide sections'2'0 are upwardly inclined to award the outer ends and that the grooves of this slide section 20V. lt will be seen that the leaf" isthus elevated above the slide secrl. leal .22a is` mounted upon Frein Figure 2it will he seen that the v 19` are downwardly inclined relative to horizontal plane. fllhesaine is true, oi course, ol the slide` sections 20a. The purpose of this will hereafter appear.

Attached tothe extremities ot the slide sections 2l is the leaf 26, and it will be noted from Figure 2l that the slidel section 2l has its upper ledge inclined upward and forward from its butt end for a certain distance, as lv`at 27, but that rtroin'the point 28 the upperv edge of the slide sectionv2lis`horizontal. The sections 2l are yalso `upwardly 40.-

and outwardly inclined. What is true or the slide section `2l is equally true of the Vslide sections 2ln and of the leaf 26a.

1iittachedtto' each leaf ,26 and extending i downward therefrom adjacent the outer in'ar-f inone direction the end of the arm 33 will inove upward.

- gin of' thel leai'is a depending member 29 adaptedwhen the leal` 26 is closed to close in the ends of the table beneath the tabletop Passing through this depending member 29is a shaft 30 which is supported in hearings 3l,` this shaft being provided at its outer end with a handle 32 and at its inner end with a lcurved crank arin 33 ca rying at its end the --ro'llergfA A spring` 35 is'connected to the crank shaftf30 so as to cause the crank arin l33to normally lie ina horizontal plane.

lwhen, however, the handle 32 is oscillated TWhen the leaves22 and 26 and 22a and 26l are disposed beneath the table `top l5 in the positionjshown in FigureB, these crank 33 lie immediately heneathfthe' cut-away por-l tionslfof the transverse supporting meinber 13, andj obviously any rotation of the crank shaftby Ineans ot the handle 32 will cause the upward movement oit' the leaves 22 and 26 or 22l and 26a.

ln the operation of this device, assuining l that the leaves are disposed beneath the table top l5, theirtheparts have Athe position shown in Figure 3 and both leaves 22 and 26 on one side and both leaves 22'LL and 26 onrthe other side are disposed inthe space between the Ytable top l5 and the upper edgev iiacesot the slides andlguides lf?, 2O and 2l and 13, 2Oa and 2la,`the table top resting` upon and being supperted by the upper tacept the,

member 13 and upon the several leaves. Now

Thiscliiis up on'the leaf ,2f/dazed the1leaf22and npwai l' on one margin 'ot the 'table top so thatthe table topA ifnlcruins on itsother margin. the time torce applied, as 'for in-L stance to thev leaf `2Gor"to thedep-ending nieinber 29, 'to vdraw this end ot the table outward. riphis extends the slides 20 and 2li.v lfVhen the leal 22 has been drawn' suliiciently ward and beyond the leaf 22, theleaf 22 wi drp into positionbehind ltheigdge of tha'. v leaf 26'and the parts will occupy-the posi;v

tion shown in Figure 2 and the table will be tully extended on the side. vllhe saine Zontal position or verticalfpositionv by ythe usual leaf springs ior this purpose.' i lt will be understood that while the table unless it is desired to y tullcapacity. It equally possi-ble temere! ly draw the leaves 22 outward from beneath the table, top, leaving the vleafv 26 beneath 'he lealQ 22'. 1While, I haveillust atedaIife'xK-rv tention tablepwith tourleaves, will un# derstood that'a greaterv nuinber, of, lea-,ves might be used it' desired, the saine principle of operation being preserved.. 'y l Thespring 35, Nas soon as'the' handle .32r isreleas'ed, acts to return the cranlrfghatfj to its initial position withy the arniv in all tion is repeated for the other side of. the leaves have been iulf" these 'legs beingheld either in' a hori-v tar outward, the tablev top laA will* drop ontok the p'roiecting ears or" thehin e and whenl the leait 26 has been drawnsurv ciently :out-g may 'bedrawn out so asr lto expose theI leaves. 2G and 26?, vet it is not,do` thisl rextend the n. table to its;

approximately horizontal position. When it is desired to contract the table, the handle 32 is operated to oscillate the shaft and raise the arm 33. This arm 33, when the talble is fully extended, bears against the under side of the leaf 22 adjacent its free edge, and when this shaft 30 is lifted, the arm 33 will raise the free edge ofthe leaf 22 so as to permit the leaf 26 to slide in underneath the leaf 22. As it slides in beneath the leaf 22, it raises up on this leaf and on the table top 15, the roller 34' rolling along the under face of the leaf 22. If it then be desired to still further contract the table, the roller 34 is moved upward by rotating the shaft 30 until vthe tab-le top 15 is lifted sufficiently to permit the butt end of the leaf 22 to be inserted beneath the table top. Then the slides and leaves are pushed home beneath the table top and the legs 36 turned upward. Thus the parts are brought. back to a fully contracted position. Of course, what is true with regard to the contraction of the leaves 26 and 22 applies equally well to the leaves 26a and 22@l on the opposite side of the table.

lVhile l have illustrated the supporting frame of the table as being mounted on the legs l2, I do not Wish to be limited to this, as the frame might be mounted upon any supporting structure, as for instance a `pedestal or compartmented supports, as in a desk. Neither do I wish to be limited to the details of construction and arrangement of parts as illustrated, as these might be varied in lmany ways without departing from the spirit of the invention.

I claim 1. An extension table comprising a supporting frame, a table top carried thereby but having vertical and tilting movement, a transverse member mounted upon the supporting frame at the middle thereof and upon which the middle of the table top normally rests, fixed upwardly inclined guides carried by the frame below said member, movable upwardly inclined slides slidingly engaging said guides and movable outward therefrom, a leaf hinged at its inner edge to said slides and hingedly supported with its inner edge in spaced relation to the upper edges of the slides, said leaf being normally disposed beneath the table top, a second set of upwardly inclined slides connected to the first named set of slides and having sliding engagement therewith, the outer end portions of said second set of slides being horifirst named leaf, and means whereby the` table top may be raised to permit the superimposed leaves to be shifted beneath the table top.

2. An extension table comprising a supporting frame having a transverse member, a table top resting upon the supporting frame, the table top having downwardly extending dowels and the supporting member having upwardly contracted sockets which said dowels rest whereby the table top may be moved vertically or tilted with inv reference to the transverse member, xed

upwardly inclined guides carried by the frame below said member, movable upwardly inclined slides slidingl engaging the guides and movable outwar therefrom, a leaf hinged at its inner endto an intermediate portion of said movable slides and hingedly supported-With its inner edge'in spaced relation to the `upper edges of the slides, said leaf being normally disposed be neath the table top, a second set of upwardly inclined slides having sliding engagement with the first named set, a second leaf carried upon the outer end portions of said last named slides and movable intoposition beyond the first named leaf, the table top and the first named leaf dropping down into position behind the second named leaf and flush therewith when the leaves are pull-ed out, and means operatively carried by the second named leaf and projecting beyond the inner edge of the second named leaf whereby the first named leaf may be raised to permit the second named leaf to be slid beneath the first named leaf and. whereby the table top may be tilted to permit the superimposed leaves tobe shifted beneath the table top, said transverse member having a thickness equalto the thicknessof the two leaves'.l j
