EXTENSION-TABLE.

SPECIFICATION forming part of Letters Patent No. 510,362, dated December 5, '1893. Application filed September 12, 1893. Serial No. 485,338. (No model.)

To all whom it may concern:

Be it known that I, JACOB POGODZINSKI, a citizen of the United States, residing at Grand Rapids, in the county of Kent and State of Michigan, have invented certain new and useful Improvements in Extension-Tables; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in extension tables of that class which employs a vertically-adjustable, solid, central tabletop and sliding leaves which are designed to be folded beneath the solid table top or to be extended in line therewith to increase the area of the table-top; and the objects in View are, first, to provide convenient means on each sliding leaf whereby the end of the table-top adjacent to the section can be conveniently elevated a sufficient distance for the sliding leaf to pass beneath the table-top, and, secondly, to provide improved means for guidmg the table top in its vertical play or movement and for limiting the inward movement of the sliding leaves; the whole being so combined and organized that the table presents a neat symmetrical appearance both when the leaves are folded beneath the top and extended flush therewith.

With these ends in view, my invention consists in the novel construction and combination of devices as will be hereinafter fully described and claimed.

To enable others to understand my invention, Ihave illustrated the same in the accompanying drawings, forming a part of this speci-.

fication, and in Which Figure 1 is a side elevation of the table showing the leaves folded beneath the top. Fig. 2 is a similar view of the table with the leaves unfolded in line and flush with the top to increase the areaof the top surface. Fig. 3 is a longitudinal sectional view through the table, with the leaves extended, showing one of the levers, N, partially depressed and liftlng one end of the table-top sufficiently for one of the leaves to slide beneath the same. Fig. 4 is a bottom plan View of the table-top, showing the relation of the leaves and the slides thereto by dotted lines. Fig. 5 is a plan view of the table frame with the top omitted.

I will now proceed to a detailed description of the preferred embodiment of myinvention, reference being had to the accompanying drawings, in which like letters of reference denote corresponding parts in all the figures.

A designates the table frame which consists of the side rails or and the end rails b which are securely united to the legs B, the whole forming a substantial structure. In the end rails 17, b, of the table frame I provide the four notches c, c, and c, c, the notches c, c, in one rail being arranged out of line with the notches c, c, in the other rail; and said end rails b,b, are further provided with the notches d, d, formed centrally thereon, for a purpose hereinafter referred to.

To the rails of the table frame is secured a false top 0, which lies a suitable distance below the upper edges of said rails, and below this false top is provided a series of drawers D,which are sustained by suitable guides below the false top so that they can slide in and out from the sides of the table, but the arrangement of the drawers is not material, as they can be placed to slide beyond the ends of the table.

Across the top of the table frame I provide a central bar E which is secured tothe side rails or of the frame in any secure manner and which serves to strengthen the frame, as the guide for the table top in its vertical movement, and to sustain the pressure or strain on the leaves when they are extended flush with the table top. This transverse fixed bar is provided at its ends with dove-tail projections e, e, and to the lower edge of this barE is fixed the guide strips 6, e, situated in proper relation to the grooves or notches c, c, and c, c, in the end rails b, b, of the table frame.

F is the table top which is made of a single piece, or of a series of pieces properly united together to form a solid top, which is of such size that it will cover the table frame when the leaves are folded beneath the same.

The table top F is provided near the sides thereof with the depending guide-stops G, G, which serve the double purpose of affording a guide for the table top in its vertical adwhereby the table top is guided in its ver-' tical adjustment and held from displacement on the table frame while at the same time the projections e fit in the grooves g in a manner to permit the top F to have a slight tilting movement which is necessary when only one leaf is extended beyond or shoved within one end of the table top.

In addition to the guide pieces G which coact with the ends of the transverse bar E, I provide a depending guide-pin H which is rigid with a shank it that is fixed to thebottom side of the table top, and this guide pin plays freely in a socket H formed in the transverse bar E and protected by a Wear plate It suitably fastened to the transverse bar over the socket therein.

The sliding leaves I, K, of my table are designed to be folded beneath the table top F to lie flush therewith or to be extended in line with said table top and flush with the same in the manner shown by Figs. 1 and 2, respectively. The leaf I is provided with the sliding bars J, J, which are fixed or rigid with the leaf so as to slide therewith. These bars are provided with the bevels or inclines j, J, on their lower and upper edges and at their inner and outer ends, respectively, so that the leaf I will be elevated to the level of the top F when it is drawn out and be depressed below said top as it is shoved beneath the same to fold the table. These bars J, J, are fitted in the grooves c, c, of the end rail b, and they are made of such length that when drawn out from the table frame with the leaf I the inner ends thereof bear beneath the transverse bar E so that the bars J have a bearing against the end rail 6 and the bar E to sustain the weight or pressure on the leaf I. The outward movement of the leaf I and the bars J is limited by means of a stop j shown more clearly by dotted lines in Fig. 4 which is fixed to one of the bars J and adapted to strike against the end rail b, and these bars .1 are limited to endwise movement by means of the grooves or notches c, c, and the guide strip e on the bar E. The other leaf K is likewise provided with the slide bars L, L, which are fitted in the notches c, c, of the other end rail 1) of the table frame, the inner ends of said bars L being below the transverse bar E so that they slide in paths alongside of the bars J on the other leaf 1. These slide bars L, L, are each provided with the bevels Z, Z, on their upper and lower edges and at their opposite ends, and one of these bars L is provided with the stop m adapted to bear against the end rail 1) to limit the out ward movement of the leaf K.

To provide for the convenient adjustment of the table top F by hand when either leaf is to be shoved underneath the top F, I provide means on each leaf whereby the end of the top F can be raised sufiiciently for the leaf to slide beneath the same while at the same time this means enables the leaf and slide bars thereon to be adjusted. This means consists of a lever N which is carried by the leaf and arranged to bear against the top F to lift theend thereof. This lever is arranged underneath the leaf and is connected atan intermediate point of its length to said leaf by means of the hinge or pivotal joint 11 at the inner edge of the leaf so that the inner end of the lever is :free to bear against the bottom side of the top. The levers on the leaves I, K, are fitted in thecentral grooves (Z, d, of the end rails 12 of the table frame, and they can move freely in said notches d, (1, when the leavesare adjusted. The levers extend nearly to the free edges of the leaves and they are formed with the finger holds n so that the levers can be grasped when it isdesired to pull the leaves out.

This being the construction of my improved table, the operation may be described as follows: With the table in the folded position shown by Fig. 1, it is only necessary to grasp the ends of the levers .N and pull the same outward, whereupon the leaves and the slide bars will be drawn out, the leavesbeing raised by the inclines on their slidebars duringtheir outward movement and the table top F dropping upon the slide bars to be sustained thereby fiush with the leaves I, K, when the latter are extended. During the outward movement of the leaves and slide bars, the table top :IS raised with the leaves and guided bytheprojections G, G,.and the pinH. To fold one leaf of the table, the outer end of the lever N is depressed to force the inner end of the lever upward and with it the adjacent end of the top F, and when the top has been raised a sufiicient distance, the lever, the leaf and the slide bars are forced inward. During the inward movement, the slidebars depress the leaf so that it passes freely beneath the end of the top F; and this top rests upon the leaf after the latter is folded so that the top remains flush with the other unfolded leaf, as shown by Fig. 3. This unfolded leaf can be shoved beneath the top in like manner by manipulating its lever N,and when both leaves I, K, are folded, they are flush with the edges of the top F as shown by Fig.

tended inllne therewith, the outer edges of the leaves being likewise rounded to lie flush with the top when folded beneath the same; but this is optional.

The outer faces of the pendent guides G, G, are made rounding or beveled at P to conform to the inner edges of the leaves I, K, and the leaves are limited in their inward movement by coming in contact with the pieces G, G, which lie in their path, the pieces G, G being finished to correspond with the leaves and thus preserve the symmetry of the table. I am aware that changes'in the form and proportion of parts and details of construe tion of the devices herein shown and described as an embodiment of my invention can be made without departing from the spirit or sacrificing the advantages thereof, and I therefore reserve the right to make such changes and alterations as fairly fall within the scope of the same. 7

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is 1. In an extension table, the combinatio with a table top, of the sliding leaf provided with the inclined bars, and means carried by said leaf for lifting the adjacentend of the table top a suitable distance for the leaf to slide beneath the top, substantially as and for the purpose described.

In an extension table, the combination of a frame having the notched bars, a verticallymovable top guided on said frame, the leaves provided with inclined bars, and a lever carried by each leaf to Work in the notched bar of the frame and have the free inner end adapted to lift one end of the table top for the leaf to pass beneath the same,-substan- 'tially as and for the purpose described.

end rails, the leaves carried by the bars, and

the levers fitted in the central notchesand each fulcrumed at an intermediate point of its length to one of the leaves, whereby the inner free end of the lever can be raisedto lift one end of the top, substantially as and for the purpose described.

4. In an extension table, the combination of a frame adapted to sustain the drawers and having its end rails provided with the cen tral and side notches and the friction rollers, the inclined bars fitted to slide in the side notches and provided with the lugs to limit their outward movement, the leaves fixed to the slide bars, the top having the pendent pieces G, G, arranged in the path of the leaves to limit their inward movement, the transverse bar fixed to the frame over the slide bars and having its ends fitted in the pieces presence of two witnesses.
