//7ve/770/ A e/h? W 77 Patented Apr. 14, 1931 @FFFEQE NELLIE W. GRIIiFIS, 0F GRESHAM, OREGON TABLE Application filed November 5, 1928.

My invention relates to folding tables and particularly these wherein the top is removably secured to the leg and rail structures. The primary purpose and object of my device is a table and top structure that may be easily and quickly removed and wherein the top may be removed for storage and shipment.

A further object of my invention resides in the leg and rail structure that may be folded to occupy a minimum of space and having a top structure that may be secured to the leg and rail portion and be used to hold the same in distended position for use. The top of which may be quickly unlocked and removed from the body portion.

It is highly desirable in tables of high quality to have one or more tops adapted to placement upon the same body portion of the table so that two or more tops may be adapted for placement upon the same supporting members and each of the tops being removable from the body portion for storage when the table is not required for use or display.

A. further object of my device resides in a compact structure that may be shipped in a relatively small package and which may be assembled, by the merchant selling the same, for display, or may be delivered direct to the user or the purchaser of the same and be assembled by him at the point of use.

Where table tops are to be used for ornamentation, and where the same are of different colors, the same leg and frame structure may be used to support table tops of difierent designs and of difierent color schemes and of different shapes. A complete table being sold in the initial sale, and other top designs be purchased from time to time to fit different color schemes and diiferent period designs. All tops being adapted to the one leg and frame support which is made standard for all and each top.

With these and incidental objects in view, the invention consists of certain novel features of construction and combination of parts, the essential elements of which are set forth in the appended claims, and a preferred form of embodiment of which is hereinafter shown with reference to the drawings which Serial No. 317,429.

accompany and form a part of this specificabody portion of the table shown distended and ready for receiving the table top thereupon.

Fig. 2 is a fragmentary, longitudinal, sectional, side elevation of the central portion of the table frame and of the locking mechanism secured to the top of the table.

Fig. 3 is a top, plan view, of the frame of the table shown folded for shipment or for storage.

Fig. i is an inverted, plan view of the table top and illustrating a locking mechanism associated with the top and adapted for looking the top, to the body portion of the table.

Fig. 5 is a fragmentary, sectional, side eleration of the locking mechanism, shown engaged with one corner of the table frame.

Fig. 6 is an inverted, plan view of the table top shown removed from the body member.

Like reference characters refer to like parts throughout the several views.

The table, in preferred embodiment, consists of two pairs of table frame members 1 and 2, each having two legs associated therewith. .Each of the frame members being hingediy secured together about a vertical central axis 3. One of the frame members is cut out at 4, to permit the passing of the other frame therethroug'h before being hingedly secured together. Each of the frames have openings 5, disposed in the top thereof into which suitable dowel pins 6, associate with the underside of the top structure, may be made to engage. In Fig. 1 the dowels 6 are shown ready for entrance into the opening 5, disposed within the frame structure. A central locking bolt 7, is disposed within the top of the central portion of the body, the same being conical in form and adapted to engage within the receiving hole 8 of the locking member. A bolt 9, is associated with the central locking head 10, which is adapted for engagement under the projecting ledge 11, of the central locking pin 7. A compressible element 12, is disposed about the bolt 9 and the bolt is adapted to being actuated through. the actuating lever 13. A suitable hand engaging loop 14 is disposed in the outer end of the actuating member 13. The locking 1 membersassociated with the under side of the table may be composed of a plurality of locking bolts, as illustrated at 4:, and each of which have locking links 14, extending there from to a central unit head 15. The head 15 having a handle 16, adapted for rotation about a central axis 17-. The rotation of the 1 locking head 15, about the central anis actih ates the locking bolts into and out of engagement within the receiving opening18, dis posed in registerable alignment with each of V the locking bolts; 'lherotation of the handle 16 intone direction, locks each of the boltsrela'tive to the body member, and the rotation of r the handle in the oppositely disposed direction'unlocks thebolts relative to the receiving notches illustrated in Fig. 5. The table top may have a ledge l9 disposed upon the under sidethereof which. would spot the table frame relative to the topto facilitate the rapid en- 7 a l i gagement" of the top relative to that of the" body portion of the table. 7 While the form of mechanism herein shown anddescribed is admirably adapted to fulfill the objects primarily stated, it is to be understoodthat'it is not intended to confine the invention to the one form of embodiment here n shown and described, as 1t 1S susceptible of embodiment in various forms all coming'within the scope'of the claims which follow.
