CENTER-REVOLVING FOLDING EX'l'NSlON-TABLE.

SPECIFICATION forming part of Letters Patent No. 528,250, dated October 30, 1894.

Application i1ed.September 19 1893. Serial No. 485.743. (No model.)

To all whom t may concern:

Be it known that I, HOWARD GRAHAM, of Ghicopee, Carter county, State of Missouri, have invented certain new and useful Improvements in Center-Revolving Folding Extension-Tables, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention relates to an improvement in central revolving folding extension tables, and consists in the novel construction, combination and arrangement of parts as Will be more fully hereinafter described and designated in the claims.

In the drawings: Figure 1 is a plan view of my improved table, parts being broken away to more clearly show the'construction of same. Fig. 2 is aside elevation of Fig. 1. Fig. 3 is a vertical longitudinal section taken on the line 2-2 of Fig. '1. Fig. 4 is an inverted plan view, showing the legs folded. Fig. 5 is an enlarged detail perspective of a portion of two rings, which I use in carrying out my invention, and a traveler.

1 indicates a central casting, which is provided with four radial projections 2. Formed on the upper side of this casting is a projection 3, which extends upward a suitable distance, the purpose of which will be hereinafter mentioned. Connected to each one of the radial projections 2 by bolts or rivets 2, are two parallel horizontal bars 4, which extend outward from the central casting a suitable distance. Each of these parallel horizontal bars 4 is provided with an elongated horizontal slot 5 which terminates adjacent its ends. Located between the parallel horizontal bars 4, as shown in Figs. 1 and 4, is another bar 6, which is horizontally adjustably connected to the bars 4 by set-screws 7 passing through the slots 5 and threaded into the bar 6. Hingedto the bar 6 adjacent its outer end, by means of hinges S, are vertical supporting legs 9.

Located on the top of the parallel horizontal bars 4 and connected thereto, is an endless ring 10, which is made of a round bar of iron.

l1 indicates another ring, which is exactly the same in construction and size, and is located on anti-friction flanged travelers 12,

said travelers being located on the top of the ring 10. A

13 indicates a disk provided with an opening in its center, through which opening,the projection 3 extends vertically, said disk being provided with the seat on the ring 11.I By this construction it can be readilyrevolved on its bearings, and forms part of the top ofthe table.

14 indicates a stationary top of the table, which is located on the outward ends of the bars 6 and 4, and is heldin position by hooks 15 being connected to the bars 4 and engaging eyes 16, which are connected to the lower side of the top 14.

The top 14 is provided with an opening in its center of exactly the same size as the disk 13.

The operation is as follows: Vthen itis desired to adjust the size of the table, the operator loosens the set-screws 7, which will readily allow the bar 6, the outward end of which carries the supporting legs 9, to be slipped outward, as shown by dotted lines in Fig. 3. After this is done the operator tightens the set-screws 7 up which will rigidly connect the bars 6 with the bars 4. When this is done the operator removes the disk 13 and the top 14 of the table, and places a larger disk and top thereon, this being the same in construction as the smaller disk and top, they being shown by dotted lines in Fig. 3. By the .construction of the disk it can be readily revolved on the anti-friction travelers and the projection 3 will hold said disk in position. By the disk being constructed andv located in this Way, when the eatables are placed th ereon and a person is sitting at the table, vhe can rotate said disk and bring the required eatables around adjacent his side of the table, and thus obviate having to disturb others at the table forfthe required eatables. The su pporting legs 9 being hinged, as shown in Figs. 2 and 3, they can readily be doubled inwardly against the bars 6, as shown'in Fig. 4. By this means the table can be made very compact for packing and shipping. l

Vhat I claim is- 1. A table of .the class hereinbefore described, consisting of a central casting 1 carrying radial projections 2, radial horizontal IOO bars 4 arranged in pairs which are provided with horizontal slots 5, a bar 6 horizontally adj ustably located between each pair of radial horizontal bars 4, a ring 10 located on and connected to the top of the bars 4, a ring 11 located above the ring 10, anti-friction flanged travelers located ou the ring 10 and constructed to form bearings for the ring 1l, and a revolubly mounted disk located on the ring l1, substantially as set forth.

2. A table constructed with a central casting carrying radial horizontal bars arranged in pairs and provided with slots, abar located between each pair of said radial horizontal bars and adjustabl y connected to them by setscrews passing through the said slots, and carrying the hinged legs, an annular tabletop located upon said radial horizontal bars, and a central disk revolubly mounted upon a portion of the central casting and upheld by 2o HOWARD GRAHAM.
