ADJUSTABLE-LEG FOLDABLIE TABLE.
Application filed September 26, 1923.
This invention relates to an adjustable leg foldable table, and its object is to produce a table which can be folded into a very small space, and which can be set up level on sloping ground or uneven ground, the table being especially adapted to be used by campers. V
Another object of the invention is to provide means whereby the adjustable legs are securely locked in any given position, while at the same time theyrcan be easily collapsed when necessary.
Another object of the invention is to so arrange the pivot points of the legs as to bring the weight on the table top on the cleats at the edge of the top thereby increasing the load supporting capacity of the ta ble.
Another object of the invention is to so arrange the parts of the table that they will all nest together when the table isfolded to produce a package only two and one half inches thick.
Another object of the invention is to provide the folding table top with means whereby both sides Will be brought down evenly and securely at the center line when the table is set up.
Other objects of the invention will a pear as the description proceeds.
' An embodiment of the invention is shown in the accompanying drawings in which the same reference numeral is applied to the same portion throughout, but I am aware that there may be modifications thereof.

The table has a top consisting of two fiat boards 1 and 2, which boards are suitably secured to the side and end cleats 3 to 8 inclusive, the opposite edge of each member of the table top having a locking bar pivoted is a side view of one of the legs Serial No. 664,911.
thereto, as shown at 9 and 10. These bars are pivoted to the top members at 11 and 12, and they have their ends rabbetted at 13 to 16 to extend under the side cleats 3 and 6, as indicated in dotted lines, Fig. 3, to secure the top members in alignment.
Two of the bars 9 and 10 are necessary to bring both top members down smooth neither alone effecting this result.
The ends of the cleats 4 and 5 and the ends of the cleats 7 and 8 are connected together by means of the hinges 17 and 18, and to form the folded package shown in Fig. 4, the cleat 6 is rovided with two hooks if? and 20 which engage screws 21 and 22 in the cleat 3, as well as with a handle 23 to carry the table.
The table top is supported at the desired elevation by means of telescoping legs which are hinged to each corner of the set up table. The table legs consist of bars 25 to 25 secured to the adjacent top end cleat 4, 5, 7 or 8 by means of the hinge members 26 to 26" retainer 27 to 27 and hinge rod 28 to 28" The hinge rod 28 is also bent at 29 to 29 and connected to the outer end of the leg by means of a double retaining cleat 30 to 30" to 'act as a'brace, said retainers also serving to pivotally hold one end of each of the several braces 31 to 31 The braces 31 to 31 have a hook at their outer ends which hooks engage the cleats 32 to 32" to hold the legs extended at right angles to the table.
Each of the legs directly secured to the table is about six-tenths the length of the desired table leg, and has a member 33 to 33 slidable along it to give the necessary table height. The two leg members 33 and 25, at each corner are secured together by a clamping rod 34, said rod being bent to pass on the sides of the legs, in back of a slotted block 35, while the ends pass into holes in the slidable member 33. Each block 35 is provided with a rubber friction pad 36 and with a spring 37 which surrounds the rod 34 to hold the friction pad against the leg 25. A pin 38 in the member 33 prevents the rod 34 from moving too far in one direction.
Of the parts 25, 25 to 38, 38 it will be seen that each table leg is so hinged that the end of the leg rests on the under side of the cleat of the table top when they are extended, and that all the parts are arranged to nest together so the folded table is of the minimum thickness, the total thickness of the table being only double the thickness of the top, plus the diameter of one of the leg braces, plus the thickness of one leg, the total thickness of a complete serviceable .table capable of holding up several hundred pounds being only two and one half inches.
The lock for the slidable legs may be made as illustrated in Figs. 7 and 8, in which the rubber friction pad 50 is retained in a flat metal receptacle 51, said receptacle being provided with punched up retaining spurs 52, 53 to hold the spring Wire locking memher 54. This member is bent to completely encircle the two legs 55, 56, and it is secured to a metal clip 57' by the two spurs 58 and 59, the free ends of the spring wire being bent inwardly together to pass through a hole in the clip 57 and into a deep hole in the leg 56, as indicated at 60, 61 said hole being so inclined as to cause the friction pad to bear on the leg with the proper grip to prevent one leg from sliding on the other ac cidentallv.
VVh en the table is to be set up the top members are opened and the center braces are turned ninety degrees. The legs are then secured in the proper position by the braces, after which the legs are extended as much as may be required in any given loca- 'tion.
lVhat I claim is as follows, but modifications may be made in carrying out the invention shown in the accompanying drawings and in the above particularly described form thereof, within the purview of the invention as defined by the annexed claims.
1. A foldable table comprising two top members hingedtogether, a locking bar pivoted on each top member adjacent its hinged edge and adapted to be turned ninety de grees to lock the top members in alignment when the table is set up, said locking members extending side by side when the table is folded together and foldable legs carried by the table top to hold it at the proper elevation, said legs so spaced, and arranged to be folded, so that the total distance inside the completed package equals the thickness of one leg when the table is folded up.
2. A foldable table comprising two hinged top members, locking bars pivotally secured to the underside of the table to bring both members into alignment when the table is set up, cleats secured on the underside of the outer edges of the top members, legs at the corners of the table arranged so that the legs on one side of the table will nest with the legs on the other side of the table when it is folded up, the arrangement being such that the folded package does not exceed the thickness of one leg plus double the thickness of the material of the table top.
3. A foldable table comprising two hinged top members, a locking bar pivoted on each top member to be turned substantially ninety degrees to lock the two top members in alignment, extensible folding legs carried by the table top to hold it at any desired elevation, a friction block bearing upon one leg, alink pivotally mounted on the adjacent slidable leg member, and a spring carried by said link and bearing on the block to hold the two leg members in a fixed position when extended.
In testimony whereof I have hereunto set my hand this 19th day of Sept. A. D. 1928.
