OVER-THE-BED TABLE Application filed September 21, 1926. Serial in. 13g 764.

My invention relates to an improvement 1n an over-the-bed table and the novelty consists in the adaptation and arrangement of parts as will be more full hereinafter pointed out.

There are many bed-sidetables wh1ch are adapted to be used alon side of the bed or which in'some cases exten over the bed. But all of these are awkward to handle and because they are not equally rigid at both ends are not well adapted for the purpose for wh1ch they must be used.

My device is simple lIlCODStIIICtlOIl but 1s e ually rigid at both ends and can be readily adjusted to the height required. Also the top of the table can be adjusted'to the partlcular pitch required thereby furnlslung 1n one table a device adapted to meet all var1at1ons in requirements as to height and being equally adapted for use as a reading or writmg supportas well as for use as a tray or utensll sup ort. My device is also adapted to be rea ily adjusted so that all parts he in substantially one plane to facilitate easy storing or acking ofthe same.

eferring to the drawings Figure 1 is a perspective of my device shown as being used over a bed which is indicated in dotted outline. Figure 2 is a vertical, section of the table top and the horizontal ax 1s and adjusting means; Figure 3 is a vert cal section of the operative parts and connectlons of the raising and lowering means, Figure 4 1s a detail of theconnecting parts, supporting legs and base members, a portion being cut away to show the interior construction. Figure 5 is a vertical section on the line 55 of Figure 4.

In the drawings 6 are the base members suported in the usual manner on castors 7 and eggs 8, having plugs 9 in the bases thereof which are internally threaded at 10, termlnate in semi-circular arcs 11 which are adapt ed to fit over and rest upon the bases 6-. The bases 6 have circular borings12 in line with the internal threadings 10 so that bolts 13 can be slipped through the borings 12 and threaded in the usual manner into the internal threadings 10' so as to securely fasten 'the bases of the legs 8 to the base members 6.

On the heads of the legs 8 are rigidly mount-- ed gear casings 14 and horizontal shafts 15 are mounted in saidcasings 14 and a pair of cut gears 16 and 17 are mounted on each of said shafts 15 so that each of said pairs of gears 16 and 17 will rotate together on their said casings14, a horizontal casing 19 they will raise respective shafts 15; A horizontal shaft 18 is mounted so that it runs through both of being rigidly mounted at 20 in eachof said gear casings 14 over said horizontal shaft 18. A worm gear 21 is cut on said shaft 18 near each end of the shaft so as to be encased in each of the gear'casings 14 and said worm gears 21 are adapted to mesh with and 0p erate the cut gears 16, and the cut gears 17 Y which rotate with the cut gears 16 are adapted tomesh with and en age the rack bars 22 which-are mounted in the legs 8 and are adapt-' ed to travel up and down in said legs. A crank 23 is adapted to be secured b means of a set screw 24 to the shaft 18 in the usual well known manner and said crank 23 termimates in a handle 25. A horizontal bar 26 is rigidly secured to the upper ends of the rack bars 22 and swivel brackets 27 are mounted'over said bar 26 so.

as to rotate'freely thereon. A table top 28 is rigidly secured by means of bolts 29 to said brackets 27 and said table top 28 has mouldings 3O rigidly secured around the edge of the same adapted to be used as retaining members. On the same end of the horizontal shaft 26 as the crank 23 and handle 25 is 'a threaded extension 31 over which is adapted to be threaded a set screw 32 having a handle 33. A circular plate 34 having a cut out portion 35 and an unusually roughened face 36 is mounted over said'horizontal bar 26 inside of the rack bar 22 and the adjacent swivel bracket 27 7 also has a cut out portion 37 and a severely roughened face 38 adapted to mesh with the roughened face 36 of the circular plate 34. A spring 39 is mounted over said shaft In operating my device toraise and lower the table top 28 the operator will turn the handle 25 whereby the shaft 18 will be ro-- tated thereby rotating at the same time the worm gears 21 which enmesh with the cut' gears 16 and cause these to rotate and atthe' same time will cause the cut gears 17 to rotate with said gears 16. As the gears 17 rotate being enmeshed therewith whereby the horizontal shaft 26 carried on the upper ends of said rack bars 22 together with all of the con nections will be raised and lowered according to the direction in which the handle and crank 23 are turned.

or lower the rack bars 22.

winged 26 in said cut outs 35 and 37. v

The table top 28 may be revolved from the horizontal position as shown in Figures 1 and 2 to such a position as is shown in dotted outline in Figure 1 or to any other desired position by means of loosening the set screw 33 'which 'will relieve the pressure on the spring 39 and circular plate 34 which with its roughened face 36 is locked in position against the roughened face 38 of the swivel bracket 27 adjacent thereto and so permitting the spring 39 to press plate 3% and swivel 27 apart thereby permitting both of the swivel brackets 27 to be turned as desired until the table top 28 is in the position sought whereupon the set screw 33 may be again turned down thereby locking the roughened face 36 of the plate 34 in a fixed position against the roughened face 38 of the adjacent swivel bracket 17 and again putting spring 39 under pressure.

In order to prepare the table for storage in the least possible space or to prepare it for packing in-a flattened condition it is' merely necessary to loosen the bolts 13 there- 'by permitting the base members 6 to be turned in the same horizontal plane as the legs-8 and the table top 28 may be turned as already described in a substantially vertical position in line with legs 8 and cross bar 26 in casings 19.

I claim:

1. In a table adapted to stand over a bed a pair of base members, 'a pair of legs rigidly mounted thereon, a top mounted on said legs, means for raising and lowering said top to any desired height comprising rack bars supporting said top, said bars being mounted in each of the legs of said table in engagement with gears in gear casings at the upper ends of said legs, said gears being operated by intermediate gears in mesh with worm gears on av horizontalshaft passing through said gear boxes said shaft being operated by a crankand handle, means for revolving said top on a horizontal axis and means for securing it at any desired point in said revolution.

2. In a table adapted to stand over a bed a pair of base members, a pair of legs rigidly mounted thereon, a top mounted on said legs,

means for raising and lowering said top to any desired bed height, means for revolving said top on a horizontal axis, said axis being mounted on the upper ends of rack bars mounted in said legs throu h gear boxes mounted on the heads of said Iegs, a cross bar rigidl secured to the head of said rack bars, swive brackets carrying said top mounted on said cross bar and means for securing said top at any desired point in said revolution, comprising a clamping plate having a sevverely roughened face mounted over one end of said cross bar, a severely roughened face on the contiguous portion of the adjacent swivel bracket adjoining cut outs in said faces and a spring mounted on said cross bar in said cut outs normally under compression between said clamping plate and said swivel bracketand a set screw mounted on the outer end of said cross bar adapted to lock said faces together.

3. In a table adapted to stand over a bed a pair of base members, a pair of legs rigidly mounted thereon, a top mounted on said legs, means for raisingand lowering said top to any desired bed, comprising a gear box secured to the head of each of said legs, a rack bar passing through each of said gear boxes and operated thereby, the gears in said boxes being operated by a shaft passing therethrough having a crank and handle at one end, means for revolving said top on a horizontal axis comprising a cross bar rigidly secured to the upper ends of said rack bars, swivel brackets mounted onsaid cross bar and means for securing it at any desired point in said revolution comprising a clamping plate having a severely roughened face mounted over one end of said cross bar, a severely roughened face on the contiguousportion of the adjacent swivel bracket adjoining cut outs in said faces and a spring mounted on said cross bar in said cut outs normally under compression between said clamping plate and said swivel bracket and a set screw mounted on the outer end ofsaid cross bar adapted to lock said faces together.
