Description

Patented Dec. 24, 1929 PATENT OFFICE GEORGE M. PATTERSON, OF KANSAS CITY, KANSAS SERVING TABLE Application filed July 23, 1928.

My invention relates to improvements in serving tables. It relates particularly to the type of serving tables in which a table top member is adapted for being lifted and revolved, so as to render articles carried by the top member readily accessible to persons seated around the table.

One of the objects of my invention is to provide novel means by which the revoluble top member may be lifted and revolubly supported. A further object of my invention is to provide a construction for effecting such function, which is simple, cheap, durable, not likely to get out of order, which is easily and quickly operable, which will not be liable to subject the articles carried by the top member to excessive jarring, and which has means for adjustment to compensate for wear or warping of the parts.

The novel features of my invention are hereinafter fully described and claimed.

In the accompanying drawings, which illustrate the preferred embodiment of my invention,

Fig. l is a side elevation, reduced, of a table provided with my improvement, the revoluble top member being shown in the lifted position.

Fig. 2 is an enlarged central vertical sectional view of the upper portion of my improved table, the revoluble top member being shown in the lowered position.

Fig. 3 is a top view, reduced and partly broken away, of my improved table.

Fig. 4 is a section on the line 4l-A of Fig. 2, looking upwardly, and partly broken away.

Fig. 5 is a section on the line 55 of Fig. 2, looking upwardly, and partly broken away.

Fig. 6 is an outside elevation of the lever locking bar.

Fig. 7 is a perspective of one of the adjustable roller supporting brackets.

Fig. 8 is a section on the line 8-8 of Fig. 5, parts being omitted.

Similar reference characters designate similar parts in the different views.

The table is provided with a support comprising a pedestal 1 on which are mounted 5 two crossed horizontal truss members 2 to the Serial No. 294,702.

ends of which is fastened a circular skirt member 3.

Respectively mounted on the end portions of the members 2 are blocks 4, which extend inwardly from and have their upper sides flush with the upper edge of the skirt member 3. On the blocks 4 and skirt member 3, and projecting outwardly from the latter, is a stat-ionary annular table top portion 5. Upon the members 2 at the intersection thereof and fastened thereto by bolts 6 is a tubular bearing member 7, which is provided with a central vertical bore.

A flat circular horizontal revoluble top member 8 is revolubly fitted within the annular stationary top portion 5, and is adapted to rest, in its lowered position, on the upper sides of the blocks A which project inwardly from the portion 5, with its top surface in the plane of the top surface of the top portion 5, as shown in Fig. 2.

A central vertical spindle 9 is rotatably and vertically slidably fitted in the bearing memer 7, and has its upper end portion fitted in a vertical hole in the lower end of a hub 10 of a member having radial arms 11.

The arms 11 are fastened to the under side of the revoluble top member 8. A set screw 12 in the hub 10 bears against the spindle 9.

For lifting the top member 8 to the elevated position shown in Fig. l, and for supporting said member revolubly in said position, I provide the following described mechanism.

A horizontal rin 18, concentric with the top member 8 and with the top portion 5, is revoluble around the axis of the top member 8 and has its under side resting on and supported by rollers ll, which are respectively rotatable on horizontal radial pins 15, which are respectively mounted in L shaped brackets 16, which respectively embrace the inner ends of the blocks 4, to which they are clamped by horizontal bolts 1? having nuts 18, Fig. 5, which bolts extend each through slots 19 provided in the arms of the adjacent bracket. Each bracket 16 has an arm 20 which extends inwardly and then upwardly, the adjacent pin 15 being mounted in alined holes 21 and 22 in the upwardly extending part of the arm 20 and the transverse portion of the Ushaped bracket. By loosening the nuts 18, the brackets 16 may be vertically adjusted on the blocks 4, to compensate for wear or warping, and the nuts 18 then tightened to hold the brackets in their adjusted positions.

On the upper side of the ring 13 are mounted U shaped bearings 23, in the arms of which are mounted horizontal pins 24 on which are respectively mounted rollers 25 adapted to bear against the under side of the top member 8, and to revolubly support the top member, when the ring 13 with the rollers 25 thereon is lifted.

To lift the ring 13, when it is desired to lift the top member 8, the under side of the ring 13 is provided with surfaces 26 which incline downwardly from the under side of the ring, and at their lower ends terminate in horizontal surfaces 27.

When the ring 13 is turned clock-wise, as viewed from above, the inclined surfaces 26 will respectively contact with the rollers 14 which will travel along the inclined surfaces, thereby lifting the ring 13, and, through the intermediacy of the bearings 23 and rollers 25, lifting the table top members 8 to the position shown in Fig. l. The top may then be rotated in either direction while resting on the rollers 25.

To turn the ring 13, it has fastened to it the inner end of a radial operating lever 28, Figs. 3 and 5, said lever being extended through an inclined slot 29 provided in an arcuate bar .30, the ends of which are respectively fastened to two adjacent blocks 4. The lever 28 is held under tension which tends to make it spring upwardly.

By swinging the lever 28 in the direction indicated by the arrows in Figs. 3 and 5, the ring 13, is revolved so that the inclined surfaces 26 ride upwardly on the rollers 14, thus lifting the ring 13 and the lever 28. hen the lever 28 reaches the upper end of the slot 29, the lever will spring upwardly into an upwardly extending recess 31 at that end of the slot, thus holding the lever from moving from the uppermost position.

At this time, the rollers 14 will have run onto the horizontal surfaces 27.

To lower the top member 8, the lever 28 .is depressed from the recess 31 and forced counter-clockwise, as viewed from above, thereby revolving the ring 13 so that the inclined surfaces 26 will pass off from the rollers 14, and the ring 13 will reach the position shown in Fig. 2.

When the lever 28 has been swung to the extreme right end of the slot 29, as viewed .in Fig. 6, the ring 13 will be in its lowermost position, and the top member 8 will again rest on the blocks 4, as in Fig. 2.

I do not limit my invention to the structure shown and described, as man-y modifications, within the scope ofthe appended claims, may be made without departing from the spirit of my invention.

l/Vhat I claim is 1. In a serving table, a support having a stationary peripheral top portion, a central top member concentric with said top portion and vertically movable and revoluble on a vertical axis on said support, means revoluble around said axis for lifting and supporting said top member, and means by which when said revoluble means is revolved in the proper direction it will lift and revolubly support said top member.
