3 Claims. (Col. S11- 93) My invention relates to a new and useful improvement in a tableembodying a top supported by a suitable standard projecting upwardly from a base.` i

It is an object of the `presentinyention to provide a table of this class having a supporting standard of adjustable length projecting upwardly from a base and provided with a brace connecting the standard to the base and automatically adjusted as toits length upon the adjustment of the `lengthof thestandard.

Another object of the invention is the provision in a table, of a supporting standard adjustable as to lengthv forl supporting,` a table topr and a brace4 for bracing the table top, automatically adjustable as to length andconnected at its end to the base in such a manner that the top, while connected to thebrace,` may be swung about the supporting standard'as'an axis.

Another object of the invention is `the provision in a table of this type, having a supporting standardadjustable as to lengthand provided with a baseautomatically adjustable as Vto length upon the adjustment of the length of the standard and so constructed andV arranged that it may hang in alignment with the standard when disconnected from the base.

Anothery object of the invention is the. provision in a table of this type of a supporting standard adjustable as to length and of novel means of securingthe standard into variouspositions of adjustment.

Another object of the invention'is the provision in a table of this type, of a brace connected to a base in such a manner thatthe connected end maybe capable of universal movement relatively to the base. u

Another object of `the invention is the provision of a table of this class which will be simple in structure, economical of manufacture, durable, compact, highly efficientin'usa'of light weight and easily folded into` compact' position. Other objects will appear hereinafter. It is recognized that various modifications and changes may be made in the table without departing from the spirit of the invention and it is intended that such variations and changes may be embraced within the claims attached hereto.

Forming a part of this specification is a drawing in which:

As` shown in the. drawng,1-.prvide a base formed from a pair of, spacedtubes-S and I0 con` `nected by the crossbars II and I2-, the ends I3 of these tubes being flattenedioutwardly. Projecting upwardly from the cross bar I2are lugs i@ in `whichis `mounted. a fittingy I5Which is pivotally. connected thereto andwhich serves as a support for the `bottom'end of a lower section IG of asupporting` standard, `the bottom end of this section being securedfto: the iitting` I5; A keeper I7 and a screw I8` servetoengage with a tongue I9 for securing the fitting I5 against swingable movementso that the standard will be inupright position as Yshown in Fig.` 1..` Mounted on.the upper end of the lower" section I6 isa collar 20 into which is "threaded a rodf2 I having the vangularly turned end' 22 so that this rod may be threaded into the interior of` the` section' I6 and engage the upper tubular section I1 of the standard` and lockit in xed relation to the lower section IB. This particular meansf of securing the sections againstslidable movementto each other is `for. the purpose of illustration as it is recognized thatvarious types of binding may be resorted .to.

Mountedon the upper end of-the section I1 of the standard is a head23'having1its upper end bifurcated` as at 24to provide the space in which the lug-2510i aiitting4 26 'may' engage. Threaded into this lug 25` is a rod 21 having the angularly turned end 28 whereby this rod may be rotated. Positioned on the rod 21 is a collar 29 which, when brought into engagement with the sides of the bfurcated portion and clamped thereto by means of the rod 21, will serve to prevent the tilting of the tting 26 on the pivot pin 30 which projects through the bifurcated portions and through the lug 25.

Secured to the fitting 26 is a pipe 3I on which engages a sleeve 32 which is secured to the table top 33 and clamped about the tube 3| by the clamping screw 34 so that the table top may be slid longitudinally of the tube 3| and locked in position thereon or rotated about the tube thereon.

The cross bar is provided with an opening 35 in which is pivotally mounted, by means of the pivot pin 36, an attachment lug 31; pivoted on this lug 31 by means of the pin 38 is the iared lower end 39 of the tubular brace section 40 which is provided, at its upper end, with a collar 4|. Fastened to this collar is a clamping band 42 which is adapted to be clamped, by means of a screw 43, about the smaller tube 44 which forms upper action of the base. The upper end of this section 44 is flared and pivoted at the ared portion by means of the screw 45 to a clamping band 46 which is loosely positioned on the section I1 of the standard and which is adapted to be clamped thereon upon a tightening of the screw 45.

By loosening the screw 43 and the screw 2|, the section I1 of the standard may be raised or lowered relatively to the section |6 so as to adjust the length of the standard. When the screw 45 is loosened, the upper section 44 of the brace will move upwardly or downwardly either inwardly or outwardly of the lower section 40 of the brace. Thus the table top may be adjusted as to height relatively to the base and, when the proper height is reached, the screw 2| would be tightened as would likewise the screw 45. As the brace is lengthened or shortened it would rock on the pin 38 as a pivot.

In dotted lines I have shown, slidably mounted on the tube 3|, a clamping bar 46 corresponding to the clampingbar 46. I have also indicated in dotted lines the upper brace section 44 connected to this clamping bar 46 in the manner that the connection is made to the clamping bar 46. Thus, if desired, the brace may be used as a brace for the table top support 4| or as a support for the standard which supports the table top. When connected as shown in dotted lines in Fig. 1 and serving as a bracefor the table top- 33, this brace may be swung with the table top as the table top is swung around the axis of the standard I6. This swinging movement is made possible by virtue of the universal connection established with the brace by means of the pins 36 and 38.

The brace is of such length that if desired it 'may be disconnected from the lug 31 and permitted to hang vertically in alignment with the standard I6. If it is desired to have it connected at its upper end as shown in dotted lines in Fig. 1, the lower end may be disconnected and swung to engage portion 31 so that it will lie parallel to the bottom of the table top. When it is desired to collapse the table, the brace may be disconnected and the screw 21 loosened, permitting the member 3| to swing downwardly into alignment with the standard |6. By rotating the member 3| with the table top 180 degrees and loosening the keeper |1, the standard I6 may be permitted to collapse onto the base as shown in Fig. 2, thus making it possible to collapse the structure into compact form for transportation or storage.

In this way I have provided a table of this type which is possessed of maximum eitciency and use and in which a very secure mounting cf the table top on the base is provided so that a rigid structure is aiorded.

What I claim as new is:

1. In a table of the class described, a base; a supporting standard mounted on said base and projecting upwardly therefrom, comprising an upper and a lower section arranged in telescopic rotative relation; means for securing said sections in fixed relation at various positions of telescopic movement and rotative movement; a table top supported on the upper of said sections; a brace comprising an upper land a lower section arranged in telescopic relation; means for connecting the upper end of the upper section of said brace to the upper section of said standard; means for securingsaid brace sections in fixed relation to each other at Various positions of telescopic movement; `and means for connecting the lower end of the lower brace section to said base for universal movement relatively thereto.

2. In a table of the class described, a base; a supporting standard secured to and projecting upwardly from said base adjacent one end thereof and comprising an upper section and a lower section arranged in telescopic rotative relation; means for securing said sections in xed relation at various positions of telescopic movement and rotative movement; a table-top supporting member ixedly secured to and extending laterally outwardly from said upper section and overlying said base; a clamping member mounted on said table-top supporting member; a brace swivelly mounted at its lower end to said base and comprising an upper and a lower section arranged in telescopic relation; means for securing said brace sections in xed relation to each other; and means for selectively securing the upper end of said upper section of said brace to said clamping member on said upper section of said standard.

3. A table of the class described, comprising an elongated base; a supporting standard secured to and projecting upwardly from, adjacent one end of, said base; a table-top supporting member xedly secured to and extending laterally outwardly from said standard and adapted for overlying said base in spaced relation thereto; a brace swivelly mounted at its lower end` adjacent the opposite end of said base and comprising an upper section and a lower section arranged in telescopic relation; means for securing said brace sections in xed rela-tion to each other; a clamping member carried by said table top supporting member; and means for connecting the upper end of the upper section of said brace to said clamping member.
