SPECIFICATION forming part of Letters Patent No. 632,111, dated August 29, 1899. Application filed May l1, 1899. Serial No. 716,420. (No model.)

To all whom, it may concern:

Be it known that I, WILLIAM R. HALLETT, of Hamburg, in the county of Oa-lhoun and State of Illinois, have invented a new and Improved Extension-Table, of which the following is a full, clear, and exact description.

This invention relates to improvements in extension-tables; and the object is to provide a table of this character witha simple means for automatically raising the intermediate leaves or sections to place while the table is being extended and for lowering the leaves while the table is being shortened.

I will describe an extension-table embodying my invention and then point out the novel features in the appended 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 a table embodying my invention. Fig.r2 is a partial end elevation and partial cross-sectional view i of the same. Fig. 3 is alongitudinal section showing the table in its normal or shortest position. the same. Fig. 5 is a longitudinal section showing one of the intermediate leaves or sections as being raised. Fig. 6 is a similar section showing the table as wholly extended. Fig. 7 is a bottom View of one of the intermediate leaves, and Fig. 8 is an edge view thereof.

Referring to the drawings, the table com-vy prises an outer frame and an inner frame, the said frames being adapted to slide one relatively to the other. The outer frame comprises the side pieces 1, an end piece 2, legs 3 at the junction of the side pieces and the end piece, and legs 4 at the opposite ends of the side pieces. Secured to the top of the side pieces and the end piece is a table-top section 5. The inner frame comprises side pieces 6, an end piece 7, and legs 8 at the corners formed by the side pieces and the end piece. The side pieces 6 have sliding engagement with the side pieces 1. As here shown, the said side pieces 6 have longitudinal ribs 9, engaging in channels 10, formed in the inner sides of the side pieces 1. The side pieces 6 are narrower than the side Fig. 4 is a bottom plan view of' pieces 1, so that there is a space between the top edges of the said side pieces 6 and the vtop edges of'the side pieces 1.

At one end the side pieces 6 have upwardlyextended portions 11, and to the upper ends of these portions 11 and to the end piece 7 a table-top section 12 is rigidly connected. This table-top section 12 is of course upon a horizontal plane with the table-top section 5.

The upper edges of the side pieces 1 are provided with recesses 13, in which intermediate leaves or table- top sections 14, 15, and 16 may rest, with their upper surfaces below the bottom place of the table-top sections 5 and 12. Mounted to swing on the side pieces 1 and below each intermediate leaf or section are lifting-plates 17. The lifting-plates 17 have journal-bearings in blocks 18, secured to the inner sides of the side sections 1, and these lifting-plates are inclined inward and upward, with their upper edges engaging with the under sides 'of the vertically-movable leaves. As a means for moving opposite lifting-plates to raise a leaf-section I employ a rockbar 19, which has pivotal connection with said side pieces 1 and has its cam-shaped ends engaging with the surfaces of the lifting-plates 17. On each rock-bar A19 is a downwardly-extended tappet 20, which is of spring material and adapted to be engaged by a shifting bar 2l, secured to the inner ends of the side pieces 6.

During their upward and downward movement the intermediate leaves or table-top sections are guided and held from longitudinal movement by means of pins 22, extended from the sections and engaging in holes formed in the upper edge of the side pieces 1 of the outer frame.

In operation when it is desired to extend the table the frames are to be drawn apart, and in this motion the bar 2l will engage with the lower end of the first tappet 20, so that during the movement of the frames the tappet will be operated to rock the bar 19, which as it engages with the plate 17 will rock said plates upward, and these plates will carry the leaf-section upward, and this will be continued as long as it is desired to insert leaves. It may be here stated that in the drawings I have shown but three vertically movable IOO leaves; bntit is to be understood that a greater or less number may be employed without departing from the spirit of -my invention. When the leaves are in their uppermost position, the rock-bars I9 will stand in the position indicated in Fig. 6 and the tappets 2O will extend in a reverse angle to their former angle, so that when it is desired to lower the leaves the frame portions of thetable may be moved together, and during this movement the front side of the bar 2l will engage with the tappets, causing the rock-bars 19 to swing to their normal position, allowingthe vertically-movable sections to fall by gravity.

I-Iaving thu's fully described my invention, I claim as new and desire to secure by Letters Patent l. An extension table, comprising two frames mounted to slide relatively to each other, vertically movable leaves, plates mounted to swing on the inner sides of one of the frames and engaging with the under sides of the vertically-movable leaves, rock-bars having their ends engaging with said plates, tappets extended downward from said rockbars, and means carried by one of the framesections for engaging with saidy tappets to swing the rock-bars,substantially as specified.

2. An extension table, comprising two frames mounted to slide one relatively to the other, a table-top section rigidly secured to each frame, plates mounted to swing on the inner surface of one of the frames, intermediate leaves with which said plates engage, guides for said intermediate leaves, rock-bars having cam ends engaging with the plates, yielding tappets extended downward from the rock-bars, and a cross-bar carried by one'of the frames for engaging with said tappets, substantially as specified.

3. An extension table, comprising two frames mounted to slide one relatively to the other, the table-top sections secured to each frame, vertically movable leaves, liftingplates mounted to swing on the inner side of one Vof the frames and engaging with the under sides of the vertically-movable leaves, the said plates being inclined upward and inward, rock-bars journaled in the frame and having cam ends engaging with the under sides of the plates, spring yielding tappets `seated in said recesses below the plane of the fixed table-top sections, lifting-plates mounted to swing on the inner sides of the outer frame, the said plates engaging with the vertically-movable leaves, rock-bars having their ends engaging with said plates, tappets extended downward from the rock-bars and means carried by the inner frame for engaging with said tappets for operating the rockbars, substantially as specified.

5. In a table, the combination with a sliding section, of a vertically-movable extensionleaf and means for raising said leaf, said means including a transverse rock-bar positively operated by the slidingsection to raise and lower the leaf.

6. In a table, the combination with a sliding end section, of a vertically-movable extension-leaf, a transversely-ranging rock-bar and lifting devices operated by the rock-bar, the sliding end section acting to rock the bar in both directions, to raise and lower the lifting devices.

7. In a table, the combination with a sliding end section, of a vertically-movable extension-leaf, a transversely-ranging rock-bar and lifting devices operated by the rock-bar, the sliding end section acting to rock the bar in both directions, to raise and lower the lifting devices, and the lifting devices being mounted to rock at right angles to the rockbar.

S. In a table, the combination with a sliding end section, of a vertically-movable extension-leaf and lifting devices for said leaf, the lifting devices including a resilient tappet which is engaged by the sliding section.
