EXTENSION TABLE.

Application filed October 20, 1926. Serial No. 142,899.

Myinvention is an extension table in which the framing of the table top may be pulled out in opposite directions and the folded leaves extended at the end of the table in objectflof my invention is the construction of an extension table in which the legs and the framing immediately connected with the frame are stationary and in which the table top and an open frame may be simultaneouslyextended in opposite directions when either the table top or the open frame is pulled.

A further object of my invention is to complete the top for the extended table by folded hinged leaves, such leaves having a sliding movement to cover, when'in the upper position the outer end of the open frame.

Afurther object of my invention is the construction of an extension table in which the extendable parts are actuated simultaneously in opposite directions; either for expanding or collapsing bya lazy tong type of connector device. 7

My invention in its various aspects is illustrated in'the accompanying drawings, in which; v v

' Figure 1 is a perspective View of the table in the closed position;

, Fig. 2 is a perspective view of the table in the extended position, showing themain top section being extended in one direction in relation to the legs, an open frame being extended in the other direction and hinged folding leaves forming a top for the open frame;

Fig. 3 is a plan view of the table extended, showing the folding leaves in their folded position, the main table top being partly broken away; c

Fig. 4 is a plan View of the table in its collapsed position. partly broken away;

Fig. 5 is a vertical transverse section on the line 55 of Fig. 3 in the direction of the arrows; V Fig. 6 is a longitudinal section on the line 66 of Figs. 3 or 5, taken in the direction of the arrows.

The table is constructed having a suitable leg structure designated generally by the numeral 1 and may have any suitable type of leg construction with a fixed frame 2 at the top of such leg construction. This fixed frame 2 is at opposite sides of the table, there being a fixed apron 3 at one end and a movable apron 4 at the other end. A guide beam 5 .is rigidly connected under the cross frame 6 of the table, such frame being stationary and being connected crosswise between the leg structures. This is illustrated as of eye-beam shape and has grooves 7 in the flanges. Slide bars 8 and 9 have tracks 10 secured to same on the loweredges, there being tracks secured to the upper flanges of the beams. Rollers 11 are suitably mounted to engage the tracks connected to the slide bars so that these may slide relative to the eye beam structure 5.

The outer slide bars 8 are connected to the block pieces 11 which in turn are se cured to the main table top 12. The inner slide bars 9 are connected to side rails 13 of an open framing 14, this framing having the movable apron 4. A pair-of lazy tong devices 15 are connected by suitable brackets 16 to the rails 13 at one end. At the center the tones are rigidly connected by a pin 17 or the like to the guide bar 5 or other structure stationary relative to the legs. Theother end of the lazy tongs is connected by a suitable bracket 18 to the main table top 12. I

The manner of operation of the extensible table is therefore substantially as follows:

When the'main table top 12 or the apron 4 is grasped and these are moved apart. the lazy tongs will cause both the top and the apron 4 with the open frame to which it connected to extend or spread apart, it being only necessary to move or pull at one end of the table. In order to collapse the table it is merely necessary to press one end, this being either the open frame or the end having the main top board 12.

The folding leaf construction is substantially as follows, having reference particu larly to Figs. 2, 3 and 5:

Such folding leaf is designated generally by the numeral 19 and has a lower section 20 and an upper section 21. The upper section is pivoted on a rod 22,the ends of the sections being hinged "together as indicated at 23. There is a fixed bar 24 which engages underneath the lower leaf section 20. It-will be noted that the edge 25 of the main board is molded and the edge of the folding leaves have a molding 26 to correspond. there being a bracket 27 on one or both of the folding sections to engage underneath the main board.

The manner of operation of the folding leaves is substantially as follows:

When these leaves are hinged upwardly the lower leaf rides on the rod 24 and raises it free and clear of the rail 13 and the lazy tong connected thereto, allowing both leaves to fold down fiat in relation to the main table top as is a known practice. The folded leaves may then be slid lengthwise on the pivot rod 22 so that the side edge 28 overlaps the apron 4 as illustrated in Fig. 2. It is necessary that the table be extended its full distance as shown in Fig. 3 to allow opening of the folding leaves and then the open frame and the main table top 12 must then be pressed together slightly so that the moldings 25 and 26 will engage. When these are'in' engagement further pressing together of the extensible parts of the table forces the edge 28 over the apron 4, thus giving a. neat finish to the table as shown in Fig. 2.

It is to be understood that my form of construction and extension table by which one part being operated simultaneously causes the other part to be operated, that it is not necessary to utilize. the foldingtype of leaves with such extension device and if desired the folding type of leaves can be utilized in another form of extension table, these leaves being at one end of the table and being pressed lengthwise of such table to overlap the ornamental trimming or apron. I

A characteristic feature of my invention is that I have a table which, when in its narrow position, has a table top without any joints covering the complete table. This top may he shifted to oneside and at the same time the open frame structure maybe shifted to the other side so thatv the folding leaves may be brought to the top, these leaves sliding outwardly on the bar 22 and fitting over the movable apron 4. Such two types of table top are clearly illustrated in Figs. land 2.-

Various changes may be made in the principles of my invention without departing from the spirit thereof as set forth in the description, drawings and claims.

What I claim is: l

- 1. An extension table comprising in combination a plurality of guide beams, a supporting structure holding saidbeams fixed,

a pair of slide bars connected to each beam to slide in opposite directions, a main table top connected to one of the slide bars, an open frame having a folding table leaf connected to the other slide bar, and means to slide :the tabletop and open frame simultaneously in opposite directions, the folding leaf forming an end of the table and having sliding motion in reference to the open frame.

2. An extension table comprising in combination a plurality of guide beams, a supporting-structure holding said beams fixed, a plurality of slide bars operatively connected to each beam to slide in opposite directions, a main table top connected to one pair of slide bars, an open frame connected to the other pair of slide bars, a lazy tong type of device having one end connected to the table top, the middle part connected to a fixed structure and the other end operatively connected to the open frame.

3. An extension table comprising in combination a supporting frame, a movable table top, a movable open frame, a plurality of lazy tongs, one end of each tong being connected to the table top and the other end to the'open frame, the mid'dle part being connected to a fixed structure whereby the table top and the frame move in opposite directions simultaneously, a pair of leaves hinged together in the open frame, a rod in said open frame, one of the leaves being pivoted on said rod wherebysaid leaves may unfold upwardly from a position below the table top and slide outwardly relative to said open frame, said leaves and the table top forming an enlarged top for a table.

4. An extension table having a main table top and an open frame, means to slide the top and the frame in opposite directions simultaneously, a folding leaf having a air of sections and hingedly connected toget er, a pivot rod in the open frame on which one of said sect-ions is pivoted, the folding leaf being slidable on said rod when in an unfolded position to slide said leaf partlyoutwardly on said open frame, and the table top and the folded leaf forming an enlarged top of a table.

5. An extension table comprising in combination a-table framing having a table top and an open frame mounted thereon, means to slide the tabletop to one side of the table framing and the open frame to the other side simultaneously and to slide the top and the frame inwardly simultaneously, a pivot rod secured in the open frame, said frame having an apron on its outer side, a leaf formed in a plurality of parts hinged together, one of said parts being pivoted on the said rod, said leaf in its unfolded position being in the same plane as the table top and slidable to overlap said apron.

In testimony whereof I have signed my name to this specification.
