ronnrna TABLE.

Application filed. January 20, 1922. Serial No. 530,516.

To all whom it may concern:

Be it known that 1, JO N R. Axonnson, a citizen of the United States, residing at Moline, in the county of Rock Island and State of Illinois, have invented certain new and useful Improvements in Folding Tables, of which the following is a specification.

This invention relates to folding tables of the type illustrated in my Fatent No. 1,252,- 7 66 granted January 8, 1-918 and has for its principal objects to increase the rigidity and durability of the structure, to improve the means for adjusting the legs, to provide a permanent connection between the transverse frame members and the table, and to provide means for securing the leg braces in position.

Further. objects will become apparent as the description is read in connection with the accompanying drawing showing a selected embodiment of the invention, and in which Fig. 1 is a perspective view of the table inoperative condition;

Figs. 2 and 3 are perspective views showing the table in different stages of being folded;

Fig. 4 is a perspective view showing the completely folded table;

Fig. 5 is a transverse section showing the manner of folding-the legs;

Fig. 6 is an inverted section illustrating the details at each corner of the table;

Fig. 7 is an enlarged elevation of a corner of the table;

Figs. 8 and 9, are sections on the lines 8- 8 and 9-9 of Fig. 6.

The top 10 of the table is composed of a plurality of longitudinally extending

sec tions

11 and 12 hinged together substantially as in my prior patent above referred to. of channel side members 13 and end memhere 14 adapted to be secured in the positions indicated in the solid lines in Fig. 2. As here illustrated, the channel members are made up of a pair of strips 15 secured to The frame of the table top is composed links are pivoted. by rivets 22 to the side wings 23 of U-shaped clips 2% formed to it the legs 25 as clearly shown in Figs. 6, 7 and 9. The clips are provided with a plurality of slots 26 through which screws 2. pass and enter the legs 25 for securing the clips 24: in position. Each leg 25 is equipped with a brace 28 pivoted thereto at 29 and having a sharpened free end 30 adapted to engage with the teeth of a rack 81 carried by the top sections 11 between the strips 15 as shown in Fig. 6. From. this figure it will be clear that the transverse framemembers 1-l lie against the ends. of the channel shaped side members 13 and are held in'place by the legs 25 when moved to operative position and secured by braces 28. In order to provide a proper engagement between the parts, the legs 25 are cut away as indicated at 32 to provide-shoulders 33 to seat against the lower edges of the transverse members 141-. This provides a very satisfactory construction, but greater rigidity and durability may be secured by fitting a cut away portion. of the'legs with the angular re-inforcements the strips 14. The presence of the metal on the shoulders 18 eliminates. a great dealof wear that would otherwise be caused'by the ends of the grains in the legs working against the side of the grains in the members 14.

In my prior construction I have provided means for adjusting the relative positions of the clips2 l and the legs The pres-.- ent invention includes an lll'lPlOVQd lIlQiLl'lS for accomplishing this result which consists of a disc 36 seated in a round cavity in each leg beneath the body portion of the clips 24 and provided with an eccentric 37 passing through a transverse slot 38 in the body of the clip. This slot should have a width substantially the same as the diameter of the eccentric 37 and should be long enough to accommodate the full throw of the eccentric. As illustrated, the exposed end of the eccentric is provided with a kerf 39 adapted to receive the point of a screw driver by which the eccentric and disc may be rotated to adjust the legs. Before operating the eccentrics, the screws 27 are, of course, loosened and after the legs have been adjusted, the screws are again set up 34 having lateral extensions which prolong the shoulders 33-on each side of the. legs and provide a greater bearing on the bottom of to retain the parts in the desired position.

-This construction is very much simpler and cheaper than that in my prior patent.

the braces 28 extend. diagonally upward from the pivots 29 to racks 31 and are retained in that position against the action of gravity by the engagement between the parts 30 and the racks 1-31, (loi'isequeutl if in use of the table, one of the was pressed outw rdly a suliicient amount to release the point 30 from the rack iii, the brace 28 wouldbe likely to fall to its operire position against the leg. To p I have extended the end of the l the pivot 29 at -0 and guide 41 for a spring I2 which is compi between the end of the brave and the bi tom of the recess 413 in the leg. With this construction it will be clear that the spring 12 will resist the movement of the brace from either its folded or its operative position, so that there will be no liability of a brace becoming released from its rack 31 accidentally in the use of the table.

The transverse frame members 1d are pivoted to links 2% which are in turn pivoted to the inner strips15 of the longitudinal frame members. The length of these links is such that the transverse members 14: can be easily placed in the positions indicated in Figs. 2 and 6 in solid lines, or folded to lie against the corresponding strip 15 when it is desired to fold the table. This is a very convenient arrangement, as it leaves no part of the table free to fall. from the bundle into which the table is folded, and. holds each of the transverse members in convenient reach when the table is being set up.

I am aware that changes may be made in the form, construction and arrangement of the invention, as set forth in the selected embodiment herein, without departing from the scope or sacrificing any of itsmaterial advantages, and I therefore reserve the right to make all such changes as fairly fall within the scope of the following 7 claims.

I claim 1.. In a folding table, the combination of of said tpp, and a link pivotally connecting each transversely extending member with one of said longitudinal members.

2. In a table, a top, longitudinal frame members including a pair of spaced strips secured to said top, transverse frame members engaging the ends of said strips, offset straps secured to said strips, links pivoted tofsaid straps, clips pivoted to said links, and legs secured "to said clips and' having means to secure them against said transversely extending frame member. 7

3. In a folding'table, a top comprising a plurality of longitudinally extending hingedly connected sections, legs hinges connected to said legs at points spacedfrom' their upper ends and to said top, transverse members adapted to be held in supporting relation to the, intermediate sections of said top by said legs, means for securing said legs in supporting position to clamp said members, shoulders onsaid legs to bear on said transverse members, and angular reinforcements secured to said legs 1 at the shoulders and extending laterally along said transverse members, to prolong the shoulders and increase the bearing on said transverse members.
