EXTENSION-TABLE.

Application filed May 4, 1915. Serial No. 25,722.

To all whom it may concern Be it known that I, I-IERMAN WIESENFELD, a citizen of the United States, residing at Vest Berkeley, in the county'of Alameda and State of California, have invented new and useful Improvements in Extension- Tables, of which the following is a specification.

This invention relates to extension tables, and has for its object to provide such a device for use particularly in kitchens, in

' which the top may readily and easily be extended and the auxiliary leaves are carried beneath the top boards, where they are hidden from view, and in no wise interfere with the free operation of the drawers arranged in the table.

Kitchen tables heretofore have been generally made extensible by means of hinged leaves which fold down at the sides of the table, and this is objectionable for the reason that these auxiliary leaves interfere with the operation of the drawers, and are otherwise inconvenient. It is not practical to employ a telescopic frame in a table of this character on account of the presence of the drawers, and for this reason detachable leaves cannot conveniently be applied to kitchen tables.

In carrying out my invention I employ slidable leaves forming the normal table top, the drop leaves designed to occupy a position beneath the slidable leaves when the top is in its narrowest width of adjustment, and means whereby the drop leaves may be raised and locked in position in line with the slidable leaves when the latter have been extended.

One form which my invention may assume is exemplified in the following description illustrated in the accompanying drawings,

in which Figure 1 shows an end view of a table embodying my invention. Fig. 2 shows a longitudinal sectional View of the table top. Fig. 3 shows a detail sectional view of the lifting, locking and guiding means for the drop leaves.

Referring in detail to the form of my invention illustrated herewith, 10 indicates a table having a rigid frame 11 carrying a plurality of drawers 12. Upon the frame are arranged two leaves 13, each carrying a pair of beveled tongues 14 slidable within crimped metallic plates 15 secured to the frame. The frame is notched intermedi- Specification of Letters Patent.

ately and one'or more drop leaves 16 normally reside in the said notches, so that the slidable leaves are free to move over them and abut each other. At each end of each of the drop leaves there is fixed a guide block' 17 working in a slotted member 18 carried by the frame, and to each of said blocks there is pivoted a lifting link 19 extending below the frame of the table where its end is accessible to the operator.

When the slidable leaves 13 have been moved apart to uncover the drop leaves the latter may be raised manually by the operator through the agency of the lifting links and when they have reached the desired elevation in a plane with the slidable leaves they may be locked by reason of the provision of a notch 20 in each of the links coacting with a lug 21 secured to the frame of the table. Thereupon the slidable leaves may be moved inwardly to close the gap between them and the drop leaves, and if desired, registering lugs and slots 22 may be employed to assist in retaining them in alined position. i

From the foregoing it will be apparent that I have provided an exceedingly simple and economical construction, easily operable to extend the width of a table top, which is particularly suitable for use in connection with kitchen tables. The auxiliary leaves are hidden from view and are so arranged and operated as not to interfere with the opening and closing of the drawers in the table.

The frame of the table may be of ordinary rectangular construction and be made to carry drawers on account of the employment of the slidable leaves forming the table top.

While I have shown and described but one form of my invention herewith, it should be understood nevertheless that it is susceptible of modification, and therefore changes in the many details of construction may be resorted to without departing from the spirit of the invention disclosed in the appended claims.

Having thus described my invention, what I claim and desire to secure by Letters Patent is- 1. In a table, a frame, a pair of leaves slidable on the frame, a drop leaf, a pair of vertical guides disposed at the ends of the drop leaf, a member aflixed to and depend ing from each end of the drop leaf and receivable in the respective guides, vertical links r pivoted to and depending from the lower ends of the respective members and to the guides, links depending from the'drop leaf and extending below the frame so that the operator may grasp said links and raise the drop leaf, and means to lock the links in raised position.

In testimony whereof I have hereunto set my hand in the presence of two subscrlbing witnesses.
