FREDERICK B. WALTER, WABA'SYI-I, INDJIANA REFECTORY TABLE Application led March 19, 1930. Serial No. 436,943.

The object of my invention is to produce an improved extension leafv structure for tables of the refectory type.

.The accompanying drawings illustrate my invention.

Fig. 1 is a plani of a table embodying my invention with portions of a fixed top leaf broken away;

Fig. 2 is a transverse section on line 2-2 of Fig. 1 showing an extension leaffink fully extended position preparatory toeither' projection to storage position or to serviceposition;

Fig. 3 is a section on line 2-'2 of Fig.1 with an extension leaf in an intermediate position Fig. 4 is a= section on line 2-'2 of Fig. 1' with an extension leaf in service position;

Fig. 5 is a section on line 2 2 of Fig. 1 with an extension leaf in storage position, and

Fig. 6 is a fragmentary section on line6-6 of Fig. 1.

In the

drawings

10, 10 indicate the side boards and 11, 11 the ends boards and 12, 12 the legs of the main frame ofthe table, the side boards 10', 10 beingprovidedv on their upper edges at their middles with upward' eX- tensions 10', `10 having a vertical height slightly greaterthan the thickness ofthe eX- tension leaves andV of such length as to provide storage pocketsv 13 for the extension leaves below the ends of the main fixed top extensions 10",

Each extension leaf 15 is supported' upon the outer ends of two

slide bars

16, 16, each of whichslides in notch 17 cut in theupper edge of the adjacent end board' 11.

"The inner ends of two opposite slide bars 16 lie slidably' supported in a Ubracket 18 secured the under face ofv top 14.

Arranged between each opposite pair o slide bars 16 and extending between the inner faces of end bars 11 of the main frame, is a cross bar 2O notched' at its upper outer corners, at 21, to correspond with pockets 13. Secured to the bottom face of each-notch 17 and forming a slide support for one lof the 50 yslide bars 16 is a. wear plate 25. Each slide 14 which is attached to vthe upper edges ofy bar 16 at its outer end is recessed on the vertical facev adjacent bar 20, at 26 and mounted in each recess isa finger plate 27 provided at its inner'end with a `finger 28 adapted `to coact, when the extension leaf is in service position with a plate 29 secured to bar and having its one end projecting into the recess 26of the adjacent slide bar 16.

`The inner end of each slide bar 16 is ren ducedin its vertical dimension, as indicated at 30 and the vertical face of said end, adj acent bar 20, is notched at 31 to receive a plate 32, having acam edge 33 adapted to coact with the horizontal bar of the U-bracket 18, v and a slide-limiting upperv cornerv 34, `said G5 plates adapted to have interlockingfrelationships with the downwardly projectingingers V and: 36 of a slide-limiting element 37' attached to the under face of a block 38 secured to the under face of top 14 within bracket 70 18'and adjacent bar 20;

V-Vhenl an extension leaf is in storage positionl it liesbeneath the adjacent end of the fiXedl leaf 14 andA its slide bar 16 rests upon the horizontal bar of bracket-18 and upon plate 755 25. When the extension leaf is pulled outwardly to the position shown in Fig. 21 the cam edge 33 ofiplate 32engages thehorizontal arm' of bracket 18 and raisesthe inner end of the slide, the catch point 34 of plate 32 80 clearing projection 35 ofelement- 37 and coming into engagement with projection ,36 of element 37 so as to prevent further outward movement;` the parts arriving at thepositions indicated in Fig. 2,. where the inner edge ofleaf 15v is positioned a short distance beyond the outer end of top 14. The leaf 15 is thenv raised and projected inwardly to -bring finger28 into engagement with the upper face of plate29, thus holding leaf 15 level 90 with top 14.

In this position the extension leaf structure pivots on the two fingers 23.,` due to the weight of the leaf 15 and brings the upper corner 34 of plate 32 in behind projection 35 95 of element 37, thus locking the extensionl leaf .against outward displacement.

' In order tovfacilitate a proper adjustment of the parts platev 27 Vis most conveniently y secured in recess 26 in the following manner: 100

At an intermediate point plate 27 is perforated at 40 to receive a screw 41. At 42 it is slotted to receive a screw 43; and at 44 it is perforated to receive a screw V45. Plate 27 is approximately located by screw 41. Screw 43 is then placed at an intermediate point in the length of slot 42 so as to frictionally retain plate 27 in adjusted position, and the plate is carefully adjusted about the screw 4l as a center so that finger 28will nicely vcooperate with the upper face of plate 29.

Screw 45 is then driven through perforation 44 to hold plate 27 in final position.

To return a leaf to storage position its outer edge is lifted so as to pivot the leaf structure upon fingers 2S until'the upper corner 34, of plate 32 is moved below finger 35 of element 37. The leaf structure is then drawn outwardly to the position shown in Fig. 2 and the leaf allowed to drop, Vwhereupon it may be projected inwardly to the position shown in Fig. 5.

It will of course be understood that the extension leaves may beA arranged either at one or both ends of the tableor at one or both sides of the table.

I claim as my invention:
