EXTENSION-TABLE.

SPECIFICATION forming part of Letters Patent No. 786,088, dated March 28, 1905.

Application filed July 18, 1903. Serial No. 166,069.

To all whom it may concern:

Be it known that I, THADDEUS C. BEACH, a citizen of the United States, residing at St. Johns, county of Clinton, State of Michigan,

have invented a certain new and useful Improvement in Extension-Tables, of which the following is a specification, reference being had to the accompanying drawings, which form a part of this specification.

IO My invention has for its object certain new and useful improvements in extension-tables; and it consists of the construction, combination, and arrangement of devices hereinafter described and claimed, and illustrated in the 5 accompanying drawings, in which Figure l is a longitudinal vertical section showing parts in elevation. Fig. 2 is a view in perspective showing parts broken away and one of the leaves removed to show the construction of underlying parts. Fig. 3 is a view in plan and partly in horizontal section. Fig. 4: is a view in vertical cross-section on the line y y, Fig. 1. Fig. 5 is a detailed view, in inverted plan, showing a dovetail engage- 5 ment of one of the end rails with one of the sliding rails.

My invention is designed to provide novel and superior means for adjusting movable leaves at the ends of the fixed portion of the 3 table-top whereby when it is desired to close the table into smaller dimensions the end leaves may be lowered and moved under the stationary portion of the table top and whereby when the table is desired to be extended the extremities thereof may be moved outward away from the fixed portion of the table-top and the adjustableleaves be elevated and held in elevated position, this movement or adjustmentof the leaves at the extremities 4 of the table being accomplished by means of improved devices by which the operation is simplified and the construction both simplified and rendered more economical.

My invention also aims to provide improved means for attaching the side rails to the tabletop by means of angle-irons recessed into both the corresponding rail and the top; also, to provide leveling devices to hold securely and in proper position the detachable leaves one with another and with a stationary table-top 5 affording a perfectly level surface upon the upper side thereof.

My invention also aims to provide other improved features of construction and arrangement, which will be hereinafter more specific- 5 5 ally described.

I carry out my invention as follows:

In the drawings, (0 represents a stationary section or fixed top of an extensible table, and 7) b are side rails connected therewith. These side rails are secured and held in position by means of angle-irons a, recessed into the corresponding portions of the side rails and of the fixed top. By recessing said plates into the corresponding parts it is obvious that they are out of the way, so as to afford no obstructicn to the movable parts of the tabletop, while at the same time they hold the side rails and the fixed top firmly together. The fixed top and side rails are so secured together 7 that the side rails have their inner surfaces parallel with the lateral edges of the fixed top and projecting a slight distance outward. therefrom to provide necessary clearance. To make a suitable finish on the exterior-,1 employ a molding (Z.

6 represents a series of adjustable or movable leaves, said leaves each provided with cleats f f at the extremities thereof The side rails b are provided with attaching side bars g g, with which are engaged transverse bars or slats h /t, the transverse bars or slats it it being thereby spaced from the fixed table-top a suflicient distance to provide for the sliding bars carrying removable leaves and to receive 5 the movable leaves in under the fixed tabletop. Secured to the transverse bars it it are fixed rails 2 z'. Sliding rails 'j have a movable engagement with said fixed rails, preferably on opposite sides thereof, so as to carry 9 removable leaves at each end of the fixed tabletop. These sliding rails j j may thus have a tongue-and-groove connectionfor example, one set having such a connection upon the inside of the fixed rails, while the sliding rails to carry the leaves at the opposite end of the fixed table have a sliding connection with the fixed rails upon the exterior thereof, as shown.

The sliding rails y'y' on opposite sides of the table are connected by transverse supportingbars 70, with which also the legs ZZ are engaged at opposite ends thereof. Each set of the sliding bars at opposite ends of the fixed table are engaged with an end rail m. The engagement of the sliding rails with the end rail is preferably a dovetail engagement, as shown more particularly in Fig. 5. The end rail is constructed with an inwardly-projecting shoulder or flange a, extending inward over the adjacent ends of the sliding rails, the dovetail engagement of the sliding rails with the end rail extending obviously only to said shoulder. This construction affords a very firm engagement of the sliding rails with the end rail. To carry the movable leaves, the sliding rails are constructed with a series of separated recesses, (indicated at preferably constructed at an angle, as shown, the lateral edges of said rails being slotted, as indicated at q q, into which slots are inserted slotted metal plates 1', preferably made of sheet metal. By slotting the recesses of the sliding rail, as described, it will be evident that the slotted metallic plates may be driven into the slots on opposite sides of each of the recesses. The slots are so located as to leave a space 8 between the slotted plate and the adjacent wall of the recess. The movable leaves are each provided with the cleats f f, as above described, said cleats being provided with screws t t, passing through the corresponding slotted metal plates upon the sliding rails. The slotted metal plates are preferably formed with elongated slots mpreferably extending at an angle to the perpendicular,each of said slots constructed at its extremities with lateral extended portions o uncommunicating therewith, the upper laterally-extending portion 4) being preferably enlarged, so as to permitthe ready insertion of the head of the screws upon the corresponding cleats therethrough. It will be evident that by moving the corresponding adjustable leaf slightly inward the screws passing through the slotted plates will be moved out of the upper lateral extensions of the slot and thence downward through the length of the main elongated slot, permitting the corresponding leaf to be lowered. Then the screws entering the lower lateral extensions of the slot will be held firmly in lowered position. A movement of the adjustable leaf in the opposite direction will of course elevate the leaf into its normally open position, and the screws entering the upward lateral extensions of the slots will hold theleaf in its proper position and upon a level with the fixed tabletop. It will be seen that in this method of construction and arrangement the sliding bars or rails are constructed with independent recesses to receive independent slotted metal plates in the marginal slots of said recesses, the heads of the screws upon the cleats of the movable leaves working freely in the spaces upon which the adjacent leaf may rest.

between the metal plates and the adjacent wall of the corresponding recess. By so constructing the sliding rails and providing them with the independent slotted metal plates the construction is greatly simplified and economized.

To hold the adjacent leaves firmly together upon a horizontal plane and to hold the movable leaf adjacent to the fixed table-top upon a level with the table-top, the adjacent edges of the leaves and fixed top are provided with tongue-and bearing plates 00, each plate being provided with an outwardly-projecting tongue, as shown, and with a bearing-surface to receive the tongue of the opposite or adjacent plate, as shown. This provision of the tongue-andbearing plates upon adjacent edges of the movable leaves and fixed table-top pro vides for leveling devices, said devices also holding securely in position the detachable leaves, giving a perfectly level surface upon the upper side of the leaves on a plane with the fixed tabletop.

It will be evident that the metal slotted plates are spaced from the cleats on the movable. leaves, thereby preventing friction. I do not limit myself to constructing the metal plate with diagonal slots, as I contemplate forming said plates with slots extending in any desired direction, my present invention not being limited to any particular shape of the slots in the metal plates. The upper lateral slots of the metal plate I prefer to have lowered slightly at their outer ends, so that the leaves when raised will rise up to place, then let down slightly, so that they will be held firmly in position. The bottom lateral extremities of the slot hold the leaf up off from the underlying parts of the table, so that the surfaces of the leaves will not rub or mar the finish.

WVhen the leaf at the end is up in position, it is constructed to ride forward slightly and drop upon the adjacent shoulder of the end rail, so that the Weight of the leaf is carried thus upon the end rail, the strain being transmitted thus to the legs of the table. The shoulder already described upon the inner surface of each of the end rails forms a ledge When closed up, the end rails form a finish with the adjacent side rails.

It will be seen that the sliding rails at each end of the fixed top section, carrying the corresponding end rails and the corresponding legs, form an extensible section or portion of the table upon which the movable leaves are carried. It will be seen also that the fixed top section with the fixed rails engaged therewith, constructed for the engagement of the sliding rails therewith, constitute a stationary section.

The plates 7 are constructed at their upper ends with laterally-extended flanges y to fit over the upper end of the slot 0. Said plates are made rights and lefts in pairs to provide ployed on the same side of the table.

for the extension of the leaves at opposite ends of the table.

The slotted metal plates r, constructed with a vertically-extended slot at and the laterallyextended slots v 20, may be made in duplicate wherever said slotted metal plates are elml is construction of said plates enables me to use the same plate for all of the different leaves employed and to separate the various leaves the one from another when required, As to the construction of the bearing-plates x, with their outwardly-projecting tongues, it will be observed that the tongue of each plate is dropped down from the body of the plate, adjacent to the corresponding edge of the fixed table top or leaf, as the case may be. Said bearing-plates are made in duplicate and are reversed in their application, so that as the two tongues of adjacent bearing-plates contact when the parts of the table-top are in elevated position and adjacent one to the other this contact of the edges of the table will prevent any lateral movement of the adjacent parts.
