BOLICK REFECTORY TABLE SLIDE 4 Sheets-Sheet 4 Filed March 24, 1948 CHARLES LEE BOL/CK Patented June 10, 1952 UNITED STATES PATENT OFFICE 2 Claims.

This invention relates to a refectory table in which a frame-work having legs is provided with centrally disposed means on the table frame for supporting the table top, thus providing a slot between the opposed sides or ends of the table top, in which slots are adapted to be nested extension leaves, and which leaves are provided with slides, and also suitable guiding members are mounted on the table frame cooperating with the slides on the bottom of the leaves, for guiding the same from a nested position beneath the table top to an extended position where they will occupy the same plane as the main table top.

It is an object of this invention to provide a refectorytable having extension leaves at the two sides thereof which are adapted to be pulled out from beneath the table top and be guided into a position where they will occupy the same plane as the table top and have the inner edges thereof abutting against the edges of the main table top. The table frame and the nestable leaves have cooperating guiding means for guiding the leaves from nested position to a position where the leaves will occupy the same plane as the table top and abut against the opposed ends of the table top. a 7

Although in the drawings the main table is shown as having the refectory leaves mounted at each end thereof, the main portion of most refectory tables are made so that the breadth is greater than their length and the refectory leaves are usually mounted at the sides of the table top, but these refectory leaves can be mounted to slide out at the ends of the table, as well as at the sides of the table, as the same principle is involved.

Some of the objects of the invention having been stated, other objects will appear as the description proceeds when taken in connection with the accompanying drawings, in which I Figure 1 is an isometric view of my improved refectory table showing one of the leaves extended and one nested and with portions broken away to show one of the slide assemblies;

Figure 10 is an enlarged vertical sectional view taken along the line Ill-40 in Figure 7;

Figure 11 is a top plan view of the table showing one leaf extended and one leaf nested;

Figure 12 is a vertical sectional view taken along the line l2--I 2 in Figure 4 Figure 13 is a vertical sectional view taken along the line l3-l3 in Figure 11; and

Figure 14 is a detail, with parts omitted, showing the restricted portion of slot 35, and its junction with slot 34.

Referring more specifically to the drawin s, the numerals l0 and H indicate side frame members of a table while the numerals l2 and I2 indicate the end frame members of the table which are suitably secured to uprising legs l5, l6, l1 and I8. Secured on top of the side frame members l0 and II by any suitable means, is a board 20 on top of which is suitably secured a main table top 2|.

The table top 2 I' has its opposite edges projecting beyond the edges of the board 20, thus providingrecesses 22 and 22' beneath each end of the table top 2| to receive nesting or

refectory leaves

25 and 25. In the drawings the refectory or nesting leaf 25 is shown in extended position while the leaf 25' is shown in nested position, but, of course, it is to be understood that in use, possibly both of the refectory leaves 25 and 25' will be moved to extended position when the table is desired to be extended as to length or width depending upon the shape of the main table top 2|.

The main portion of the table having been described, the means for mounting the refectory leaves will be described, and the left-hand end of the table, such as shown in the drawings, will be described and like reference characters will apply to the right-hand end with the prime notation added. Also, since the sliding mechanisms on both sides of the table at each end thereof are identical, except for opposite hand arrangement of the same on each end of the table, like reference characters will apply to all of the slide assemblies.

Secured to the lower surface of the main table top 2| by means of screws 26 and removed from member SI has a horizontally disposed slot 33 therein which projects to near the outer end thereof and has an upwardly directed slot portion 34 and a reversely bent slot portion 35; To the lower surface of the refectory leaf 25'a'resecuied" by screws, 29, leaf guide members 39, preferably in the form of channel bars, which are closed at both ends to add rigidity to the same. guide members 39 have sliding movement in notches 36 disposed in the end frame member H,

and extend inwardly beneath the outeredge of the table top 2| and through the slots 35 and their inner ends are adapted to fit into cavities 38 in the outer edge of the board member 20 when the leaf25isextended. 7 I n The leaf guide member 39 is positioned alongside the outer side of the frame guide member 3 i and the leaf guide member 39 has an irregular slot extending longitudinally thereof which, has,

an inner portion 49 which is slightly inclined upwardly as it is directed towards the centeror the table, and at the outer end of the slot portion 43 it is merged with an upwardly and outwardly inclined slot portion 42 which-merges with a horizontally disposed slot 33 disposed immediately below the top web of the leaf guide member The frame guide member 3| has fixedly mount ed therein a stud 45 comprising a circular portion 46 adapted to have movement in the

slot portions

40, 42 ands}; and this stud or rivet has an enlarged head portion d1 which prevents dislodgement of the portion 46 from the slot por tions 4!), 42 and 33. The leaf guide member 39 has likewise mounted therein a stud or rivet 50 which has a portion 52 adapted to slidably move in the

slot portions

33, 3d and 35 and has an enlarged head 54 which confines the portion 52 1 within the

slot portions

33, 34 and 35.

, In cutting the

slot portions

33, 3d and 35, there is leftj an unsupported tongue 6!] and inorder to properly support this tongueiiii I, provide a rivet 6| which penetrates a spacer collar 62 which is disposed betweenthe tongue 68 and a plate 63 which is welded between the side angles of the frame guide member 3i, and the rivet 6i hasits ends bradded on the outer surfaces of thetongue 6B and the plate 63 to'thus properly support the tongue 63 to keep it from being bent laterally. It will be noted that the head of the rivet in' the right-hand side of Figure 3 is countersunk soa s to avoid its interfering, with relative sliding movement between the leaf guide member 39 and the frame guide member 3| Whose proximate sides are close to each other. 7 V 1 It will also be noted that the inner ends of the leaf guide members 39 are sloped inwardly and The leaf.

provide a stud l on'the tongue portion 66) of frame guide member 3| and on this stud HI I pivotally mount a spring clip 12 which is of re stricted U-shape in form and has a reversely bent end 13. When the refectory leaf 25 is moved outwardly in the slot portion 35 to nest the same, the spring clip 12 is moved to the position shown in Figure 9 and when the leaf 25 is brought outwardly and raised to the piis ition'shown in Figure 4, being pushed inwardlyfitwill cause the member F2 to occupy the position shown in Figure 8.

.Another difference in the structure shown in Figures 7 to inclusive is that, instead of having ariiietas'described in the preceding figures, the

I rivet'45,having the portion 46 for sliding movement the slots, and having the enlarged portio'n'48'for confining the rivet in the slot, has the portion 45 of slightly less diameter, and this portion 46 is surrounded by a roller to cause ease .of operation. It is'thus seen that as head 58, positions the spr ng, member 'l'2 as shown in Figure 8, when'tlieleaf Z5jis in the position shown in Figure 4, whereas when the refectory leaf is pulled outwardly" to'where it can be lowered to nes'ted position, the head 43 will cause the spring clip. member T2 to occupy the position shown in Figure 9;

flheg's'lots'33'. and .34 and the outer portion of slot lare wide, enough for the portion 46 or roller 15 to have free movement therein, however, in ordentoupro'duce" a binding effect on the roller 15 or, portion 46 during, say the last downwardly to facilitate their moving inwardly and through the slots 38 in the board member 29,

and also to facilitate their moving under the board member 20 when the refectory leaves 25 are being moved to nested position.

In Figures 7 to 10 inclusive a modified form of p the invention is shown in which like reference characters will apply to like parts, the main difference being that in order to releasably lock the refectory leaves 25 in extended position, I

hal'f inch ,oftravel in; slot 35, the slot as is restricted ,as atishioulder also roller 15 or portion 46 wilrhaveja tight fit'otherein to thus bind the refectoryleaf operating'or extended position ar'l'djpreventl its being movedeasily outwardly away from the edge of the table top 2|.

vIt is ,thus seenthat .I haveprovided a refectory table, in whichthe slides are metallic and thus not subject to: swelling and shrinking during chang 'inweath'er; and also one which is positi'yef i'n operationandhaving, means whereby the refectory leaves, can be locked in extended position and whereby they can quickly be nested in a matter of a few, moments of time.

B ihev n as tainneeehe the frame guide members and the le af guide members, it is possible to provide a; refectory table having a much shorter main tabletop than, is possible where both slots arein only oneof the guide members. In the drawingsl and specification there has been setforth a preferred embodiment of the invention, and although specific terms are employed, they are used in a generic and descriptive sense only and notfor purposes of limitation, the scope of the invention being defined in the claims Iclaim't h In a refectory table slide frame consisting o'f a frame guide member having inner and outer ends and having a ,J-shaped guiding slot out therein, theou'ter end o'fwhich is directed'upwardly and then inwar ly, a leaf guide member disposed alongside the frame guide member and having an inwardly projecting portion provided with a slot near its inner endwhich extends slightly downwardly as it progresses toward the outer end of the leaf guide member and then projects upwardly and outwardly and then extends horizontallyioutwardly toward the outer end of the leaf guideinember, a guiding pin secured on the frame guide'me'mber and'having movement in the slot in'the' leaf guide member frame guide member, the two slots in the frame guide member and the leaf guide member being in super-posed offset relation substantially throughout their length when the slidable leaf guide member is in extended position relative to the frame guide member, the lower wall of the short leg of the J-shaped slot having a cam surface thus diminishing its width to elevate the leaf guide member as its guiding pin is moved toward the closed end of the short leg of the J-shaped slot.
