EXTENSION-TABLE.

SPECIFICATION forming part Of Letters Patent No. 625,173, dated May 16, 1899.

Application filed May 6,1898. Serial No. 679,957. (No model.)

To all whom it may concern:

Beit known that I,JOHN THOMAS LATURNO, of Grand Tower, in the county of Jackson and State of Illinois, have invented a new and Improved Extension-Table, of which the following is a full, clear, and exact description.

The object of the invention is to providea new and improved extension-table arranged to place any desired number of auxiliary leaves automatically and successively in position upon drawing the table-sections apart to the desired length of extension.

The invention consists of novel features and parts and combinations of the same, as will be described hereinafter and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification,

. in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of the improvement in a closed position. Fig. 2 is an inverted plan view of the same. Fig. 3 is a sectional side elevation of the same. Fig. 4 is a similar view of the same with the auxiliary leaves in place and the table extended to its full capacity. Fig. 5 is a sectional plan view of the improvement on the line 5 5 of Fig. 3, and Fig. 6 is a transverse section of the same on the line 6 6 of Fig. 3.

The improved extension-table is provided with two main sections A A, having table-tops B B, respectively secured on frames 0 C, carrying the legs D D, respectively. The sections A A are slidably connected with each other to permit of drawing the sections apart, as shown in Fig. 4, for extending the table or moving the same together, as illustrated in Figs. 1 and 3. For this purpose the section A is provided atthe under side of its frame 0 with longitudinally-extending bars E E, secured to said frame and extending underthe frame 0 and having longitudinal slots E through which extend bolts F, secured to a transverse beam F, carrying a leg F forsupporting the table at its middle.

On the top of the beam F is pivoted a catch G, (see Figs. 3 and 4,) adapted to engage a keeper G, secured on the frame-O, said catch being provided with an upwardly-extending arm G pressed on bya spring G for holding the catch G normally in engagement with the keeper G and locking the beam F firmly to the frame 0. When the sections A A are drawn apart, the beam F, owing to the catch G engaging the keeper G, moves with the section A until the sections are drawn apart about half the distance of the full extension,

and at this time a transverse beam II, sup

ported from the frame 0, engages the arm G and swings the same into the position shown in Fig. 4 to cause the catch G to release the keeper G, so that during the remaining half of the extension the beam F moves with the frame 0 and stands in the middle of the table when it is fully extended, as shown in Fig. 4.

Auxiliary leaves I, J, K, andL are normally arranged under the table-tops B B, as illus trated in Figs. 1 and 3, the leaves I and J being under the top B and the leaves K and L under the top B. The leaves I and J are rigidly mounted on longitudinally-extending arms I and J, pivoted at I and J 2 to the top surface of longitudinal bars F attached to the beam F and extending loosely over the bottom of the frame 0', each of the arms I J being provided at their sides with downwardly-extending lugs I J adapted to travel successively up the inclines N, formed on boards N, secured to longitudinal beams N fastened to the bottom of the frame 0, as is plainly indicated in Figs. 4 and 5. The two boards N are connected with each other by the cross-bar H, previously mentioned, for operating the catch G. The other leaves K and L are likewise provided with arms K L, extending longitudinally, but in an opposite direction to the arms I J for the leaves I J, said arms K L being pivoted at K L respectively, to bars F likewise secured to the beam F. The arms K L are provided at their sides with lugs L K respectively,

adapted to travel successively up the inclines O of boards 0, secured on bars 0 extending longitudinally and secured to the bottom of the frame 0, as indicated in Fig. 5.

Now it is evident that when the table-sections are drawn apart the beam F willmove' with the section A, as previously explained, so that the lugs I first come in contact with the inclines N as the arms I J move outward with the section A, and the incline N on the board N moves the latter in the opposite direction to the section A. Vhen the lug 1 travels up the said inclines, it imparts a swinging motion to the arms I, so that the auxiliary leaf I is moved into the space between the adjacent inner ends of the tabletops B B, the lugs I then riding and resting on the horizontal top ofthe boards N. On a further movement of the table-sections the lugs I will ride up in the same manner on the inclines N to move the auxiliary leaf J into the space between the adjacent edges of the table-top B and the leaf I already in place. At this time the bar H has released the catch G from the keeper G, so that on a further outward pull of the sections A the lugs K travel up the inclines O of the boards 0 and move the section A into the gap between the adjacent inner edges of the table-top B and the auxiliary leaf I, the lugs K then riding and resting on the horizontal top of said boards 0. On a further outward movement projections L ride up the inclines O to swing the last auxiliary leaf L into the space between the adjacent inner edges of the top B and the leaf K alreadyin position. The side edges of the several auxiliary leaves I, .I, K, and L, together with the inner edges of the table-tops B B, are beveled in the manner indicated, so that the leaves will form proper joints and readily move into position to form a continuous extended table-top, as indicated in Fig. 4.

In order to lock the sections in position after an auxiliary leaf is moved into place I provide the following device: On one side edge of the bar E are formed notches E arranged a distance apart corresponding to the width of the auxiliary leaves I, J, K, and L, and said notches are adapted to be engaged by a bolt P, pivoted at P to a bar Q, arranged alongside the bar E, but secured tothe frame 0. The pivoted bolt P is pressed on at its outer end by a spring P for holding said bolt in engagement with the corresponding notch, and said bolt is also connected at its outer end with one end of a rope R, (see Fig. 2,) extending through eyes R R secured to the bar Q, and thence passing transversely and up through an opening R formed in the bottom of the frame 0. On the end of the-rope R is arranged a ring or other suitable handle R within convenient reach of the operator at this end of the table, so that when a pull is exerted on the ring R then the rope Rswings the bolt P out of engagement with the corresponding notch E against the tension of the spring P to unlock the two sections A A. As the bar E is fastened to the bottom of the frame 0 and the bar Q, carrying the lockingbolt P, is secured to the other frame 0, it is evident that the bolt P securely locks the sections A A together when engaging one of the notches. WVhen the operator releases the pull on the handle R, the spring P returns the bolt P to its previous position.

.In order to manipulate the bolt P from the other end of the table, if desired, I provide a second rope R passing through eyes R R and then through an opening R in the bottom of the frame 0, to carry at its end a handle R within convenient reach of the operator at the end of the section A. The operation ofthis rope relative to the bolt P is the same as described with reference to the rope R.

In order to strengthen the table when extended, I provide two longitudinally-extend ing beams S S, of which the beam S is secured to/the frame 0, and the other beam S is secured to the outer end of the frame 0. The free ends of the beams S S are provided with guides S S, respectively, engaging the free ends of the beams S and S, respectively, so that when the sections are drawn apart and slide one on the top of the other the guides will connect the beams with each other, even when the table is fully extended. As illustrated in Figs. 5 and 6, two such sets of beams S S are providedone for each side of the table.

Now when the several parts are in the position illlustrated in Figs. 1, 2, 3, and 4, and it is desired to extend the table by the addition, say, of the auxiliary leaf I, the operator pulls on either ring R or R to unlock the sections by withdrawing the bolt P from its notch E and upon pulling the sections apart the beam F moves with the sections A, and the arm I of the auxiliary leaf I likewise moves with the frame 0, while the inclines N on the boards N move with the frame 0, so that the lugs I travel up the inclines N and impart a swinging motion to the arms I to move the auxiliary leaf I into the space between the table-tops B B. When this takes place, the bolt 0 snaps into the next notch E and locks the two sections A'A again together with the leaf I in position to complete the extended table-top. If a second leaf is desired, the sections A A are unlocked and pulled farther apart to cause the lugs J 3 to travel up the inclines J and swing the auxiliary leaf J in position, as previously explained. If more leaves are desired, the sections are drawn farther apart to cause the lugs K to travelup the inclines O and swing the third leaf K in position, and finally the lugs L travel up the inclines O and swing the fourth leaf L in position.

As illustrated in Fig. 1, the sides of the frame 0 are formed with slots to permit the ends of the auxiliary leaves I, J, K, and L to extend sufficiently to the sides of the frames, according to the width of the table-top.

Having thus fully described my invention, Iclaim as new and desire to secure by Letters Patent 1. An extension-table comprising two separable sections, arms pivoted to swing in the arc of a circle at the central portion of the table and carrying extension-leaves rigid with said arms so as to be capable of moving from an inclined'position to a horizontal position, and means for moving said leaves into position as the table-sections are moved apart.

2. An extension-table comprising two separable sections, a leg-beam located between said sections and having a sliding connection with each of them, a device for temporarily locki ng said beam to one of the table-sections, mechanism for releasing said beam when the table is about half extended, extension-leaves inovably supported by said leg-beam, and means for bringing said leaves into position as the table-sections are moved apart.

3. An extension-table, comprising two sections fitted to slide apart, a leg-beam, a looking device for locking the said beam to one section, and means, substantially as described, and carried by the other section, for automatically unlocking said locking device at the time the sections are drawn apart to about half of their full extension, as set forth.

4. An extension-table comprising two separable sections, arms pivoted to swing in the arc of a circle at the central portion of the table and carrying extension-leaves rigid with said arms so as to be capable of moving from an inclined position to a horizontal position, and inclined projections carried by the tablesections and arranged to successively raise the extension-leaves as said sections are moved apart.
