The object of the presentjinvention is to pro-' vide a table of the character above referred to in which the top can be tilted and/ or set at different heights by means of a bar frame incorporatingfa novel combination and arrangement of telescopic and swivel parts.

The invention is illustrated in the accompanying drawing in which: p

Fig.1. is a front elevation of the table.

Fig. 2 isa top plan view thereof.

Fig. 3 is an end elevation of Fig. l.

Fig. '4 is a detail showing a swivel connection between the base of the frame and one of the uprights or legs. r r

Fig. 5 is a perspective view of the lower portion of the frame.

The invention is shown and will be described as an overbed table. The top, denoted'at -6, is an ordinary member presenting a flat upper surface.

which'may be supplied with a marginal rim asdepicted. Said top is of a rectangular configuration; being in the present instance of a' greater length than width.

The metal frame is composed of tubular bars, there being provided a front member and a back member, both of a U-shape in configuration and united at the base portions. These members extend parallel to each other and longitudinally of the top 6. The front member comprises an upper section I, a lower section 8 and a side section 9 which forms a leg or upright at an end of the top 6. Said side section is a telescopic element consisting of a rigid upward continuation ID of the lower section 8 and a downward continuation ll of the upper section I slidably arranged for vertical extensile movement and adapted to be clamped in a set position as by a clamp l2. Any suit-able clamp device may be employed. In the present instant this is formed by slotting the upper end of the part ID, as at l3, and providing ears H on the slotted portion connected by a handled screw l5 by which they can be drawn together to apply-clamping pressure on the telescoping part I l.

The upper section I i loosely sleeved in bearings l6 secured to the under side of the top 6 7 Claims. (01. 311-37) to provide a swivel or hinged connection there-- being used to prevent with, conventional means end play of said section in the bearings.

The back member is similar I the front 'member'and comprises an upper *section' Il a. lower' section l8, and a side section forming a leg or upright which lstelescopic. This leg or upright consists of the telescoped parts 20 and 2l which are adapted to be secured together by a clamp 22 similar to that previously described. The part 20 is a downward continuation of the upper section I! and is' journalled'in bearings use of the clamping devices on the telescopic legs,

23 attached to the underside of the top '6 to pro} vide a swivel or hinged connection therewith.

' The part2! is an upward articulate continuation of the lower section 18 and has a swivel juncture 24 therewith so that'it may swing to and away from the "front member 9. The swivel juncture may consist of interfitting elements having a common retaining device 25.

The lower section 8 of the" corresponding section I9 are rigidly tied together as 26. I

From the preceding description it will be manifest' that-theirivention provides an adjustable table'that can be placed over a bed, and one in whichthe top can be raised or loweredby the IB of the back member by the crossbars top can be tilted to any desirable Additionally the to a greater height angleby raising one of the legs than the other; In doin'g's'o the leg from its swivel connection 24 to accommodate the hinge movement of thetop which is the important feature of construction.

What I claim is:

1. In a tilt table, a top having a front edge and a supporting frame therefor, said frame comprising a base part for resting upon a supporting surface, and spaced upright members forming a connection between said top and said base part,

and arranged one in advance of the other with respect to the front edge of said top, the lower end of one of said upright members being rigid with said base part and the upper end thereof being hingedly related to said top, and the other upright member being formed with lower and upper sections permitting of telescopic adjustment,

said upper section thereof being hinged to said.

top, and said lower section thereof being hinged to said base part to provide a pivot whereby the last mentioned upright member is free to move angularly to and away from the other upright member in setting said top to different angles by the use of said telescopic adjustment.

in construction to the front member 9 and 2. In a tilt table, a top having a front edge, and a supporting frame for said top, said frame comprising a base part for resting upon a supporting surface, spaced upright bars forming a connection between said top and said base part and arranged one in advance of the other with respect to the front edge of said top, the lower end of one of said bars being rigid with said base part and the other end thereof being hinged to said top, the other of said bars having telescopable sections and being hingedly connected to said top and to said base part to move angularly out of perpendicular in setting said top to difierent angles by means of said telescopable sections, and.

locking means for said telescopable sections.

3. In a tilt table, a top having afront edge; and a supporting frame for said top, said frame comprising a base part for resting upon a supporting surface, spaced upright bars forming a connection between said top and said base part and arranged one in advance of the other with respect to the front edge of said top, said bars having telescopable sections, the lower end of one of said bars beingrigid with said base part and the other end thereof being hinged to said top, the other bar being hinged to said top and tosaid base part sorthatiit may swing to accommodate telescopic. adjustment of one of the. bars relative to thevother in the tilting of said top, and means for releasably locking together said telescopable sections of each of said bars.

4. A-tilt tablecomprising a top, and, a supporting frame, the frame being made up of a base part, a pair of tubular members upstanding therefrom and disposed one in advance of the other, either of said members have upper and lower sections for telescopic action, said members being bent at right angles at their upper ends to extend paralleliybeneath said top trans,- versely thereof to form horizontal sections, bearings loosely sleeved on said horizontal sections to hingedly attachthem to said top, the, lower sec,- tion of one of said members being rigid with said base part and the lower section of the other member being hingedly connected to said base part, and means for releasably locking said upper and-lower sections together when telescopi-' cally. adjusted.

5. Aitilt table comprising a top, and a frame made up of tubular bars providing U-sha'ped front andback members having upper, lower and sidesections, theside sections being erectile to form legs, the upper and lower sections being 4 horizontal and having continuations bent to form said side sections and slidably interfitted for extensile movement, one of the continuations of the lower sections being rigid and the other being sleeved to form a swivel joint, crossbars rigidly uniting said lower sections, bearings loosely sleeved on said upper sections and swivelly attaching them to the underside of said top, and means for releasably lockingsaid slidably interfittedcontinuations of which said side sections are severally composed. I Y' 6. A tilt table comprising a top, and a supporting frame, the frame consisting of a stable base,

a pair of legs havin telescopic lower and upper parts, said legs being disposed one in advance of the; other and the lower part of one of them being rigid with said base and the lower part of the other one being swivelly connected to the base so that this leg may swing bodily out of the perpendicular, means for securing the telescopic parts of the legs in set positiomand means swivelly attaching the upper part of each leg to said top so that parallel axes are provided by which said top can betilted by telescopic adjust ment. v p 'Z. In a tilt table of the class described comprising a U-shapedrigid tubular base having a pairof tubular bars extending vertically from the ends of the U, a pair of L-shaped tubular bars having their vertical leg-forming sections telescoped within said vertical tubular bars, a table top pivotally secured to said L-shaped bars, and

means at the uDQQrends of said vertical tubular bars for securing said leg-forming sections whereby to lock said L-shaped bars in any desiredposition; the improvement including means for enablin said'vertical tubular barsto have.

relative angular adjustment to accommodate tilting of said table top, said means includinga pivotal connection between one, ofsaid vertical tubular bars and an end of, said U of the said base.
