' A cheap and convenient form 'of bolt constructionis shown in Figs. Sand 9. The body yof theV bolt vis made from round bar stock threaded at one end. The other end is turned down to form a cylindrical shanklO of uniform diameter with a shoulder e1. A series of square-sided washers 42 are slipped overy this shank l0 and held in place by upsetting the projecting portion of the shank at 43. These washers are prevented from turning on the shank by milling' aiiat on one side of vthe `shank vand forming the aperture Ain the washers with a complementary 'flatportion The rectangular chamber which receives the caps 24 and the head of thebolt 27 need not 4be of any standard size kto enable they Washers to be* formed Lfrom strip material of stzluidard width. The washers may be made l from strips narrower than the internal width length equal tosuch width and are threaded on the shank Ll() in staggered relation, asV

` 23a of sheet metal. vof such caps provided that they are cut to a l'wardly extended or splayed position. rlhis is accomplished in the construction shown by the top 12 when the legs are outwardly cutting the tops of the legs so that their np- I per surface is flush with the upper surface of extended position. Vith the legsso formed,

linward movement of the legs involves raising the tops of the latterabove the'upper edges of the U members of the top 12 and this is impossible when the plate le is clampedvdown on the top 12 "bythe action of tne nut 25 and the lOOlt 27;' l Y l The bottom of each leg' maybe closed'by'a bentstrip of metal-411 spot-welded in place. f

The form of construction shownin Figs. 10 to 14,'inclusive, differs from that shown-in Figs. 1 to 9,*inclusive, chiefly in the manner in which the-.base of the table top is connected to the upper partr of the table support. ln

the formoffconstruction above described, the Y In the modification ofFigs. 10 to le, the connecwelded a flange of one of four long angle `bars la. f The angles 15a and angle vbars 15a are soarranged as to leave a central space at thei center of the plate 14a'.

The table support comprises a top 12a formed of four sections of sheetinetal bent into U-form and, each Ahaving `a long arm 19a, vand a shortV arm 20a, assembled as described in connection with the corresponding parts of Figs., 1 to 9, in elusive. These parts are spot-welded together as in the construction of Figs. 1 to 9, and are further locked `together by members At the upper end of the central square chamber and resting on the upper edges ofthe members 23a is a split centrally vapertured cap 37. l Between lthe two halves of this capa boss 32 is arranged, thisv v.boss having an annulargroove into which the inner edgesv ofv the two halves of the cap eX- tend to lock the boss 32 in position. vAfter assembly the parts of the cap are spot-welded to the arms 19a. y The plate 14u/is formed with a centralaperture 33 having adiameter each other. The boss 32 has a tapered top to facilitate the insertion of the boss into the vaperture 33. Y

To the inner face of the central web 34: of each U-shaped member is welded a rigid plate 35 with an inturned flange 36 atits upper end. The underside of this flange is spaced above the top of the cap 37 a distance equal to the combined thicknesses of the plates 14a and 31. The distance between the inner edges of diametrically opposite flanges 36 is somewhat greater than the diameter of the plate 14a, so that the latter can be passed downwards between the flanges. Welded to the top of the plate 14a are four equally spaced plates 31, arranged with their ends projecting sufficiently beyond the periphery of the plate 14a to engage the underside of the flanges 36, as shown in Fig. 14, when the table top and its base have been turned clockwise through the requisite angle with respect to the top 12a of the table support.

To retain the ends of the plates 31 in engagement with the flanges 36, a springstrip 38 is attached at its lower end to the'inner face of one of the central webs 34. The upper part of this spring strip is bent inwardly so that when the end of one ofthe plates 31 has been forced over it by the above mentioned clockwise movement, this strip will spring back behind the plate 31 and hold the table base and table support in locked position. It will be noted that the depending flanges of the angle bars 16a extend below the tops of the plates 35, their flanges 36 and spring strip 38, so that clockwise movement of the table top beyond that required to force one of the plates 31 past the spring strip 38 is prevented by such flanges. The table top can, therefore, only be detached by turning it in an anti-clockwise direction.

The corners of the projecting ends of the pla-tes 31 are beveled so as to allow the latter to be forced past the endV of the spring strip 38 in either direction. As, however,^the force required to accomplish this movement is greater than any force applied to the table in the course of ordinary use, the table top is firmly held in position by such spring strip until it is desired to disassemble the table.

In the form of construction last described, outward movement of the legs 13 prior to engagement of the table top with the table support is limited by engagement of the inner edges of the leg tops with the inner walls of the radial pockets in the top 12a. At no time do the sides of the legs engage the lower margins of the central webs 34. as in the form shown in Figs. 1 to 9, inclusive. After the table top has been brought into engagement with the table support, the legs are held in correct angular position by engagement of their beveled upper ends with the underside of the plate 14a.
