SELF- WAlTlNG TABLE.

SPECIFICATION forming part of Letters Patent No. 628,153, dated July 4, 1899.

Application filed July 12,1898. Serial No. 685,777. (No model.)

To all whom it may concern.-

Be it known that I, ANDREW J. YORK, a citizen of the United States, residing at Red Boiling Springs, in the county of Macon and State of Tennessee, have inventeda new and useful Self-Waiting Table, of which the following is a specification.

Myinvention relates to self-waiting tables, and particularly to the combination, with a dumb-waiter and means for operating the same, of a table-cover and fan mechanism, together with operating devices.

The objects and advantages of this invention will appear in the following description, and the novel features thereof will be particularly pointed out in the appended claims.

In the drawings, Figure 1 is a perspective View of a table constructed in accordance with my invention, the cover being shown in its depressed position and the fans folded. Fig. 2 is a central vertical sectional view of the same, showing in full lines the cover in its lowered and in dotted lines the same in its elevated position. Fig. 3 is a detail view of the means for elevating the table-cover. Fig. 4. is a horizontal sectional view of the same, showing the supporting-plate in plan.

Similar numerals of reference indicate corresponding parts in all the figures of the draw- 1ngs. I I

1 designates the main tabletop, which is preferably circular, and 2 the table-frame, including skirting-boards and supporting-legs. Supported under the table-top is a frame consisting of an upper plate 3, a lower plate 4, and an intermediate plate 5, connected by bolts or rods 6, which also serve as the means whereby said frame is secured to the tabletop, and mounted in vertically-alined bearings in the upper and intermediate plates of the frame and also extending through a central opening in the table-top is a tubular shaft 7, terminating at its upper end in a wing-nut or operating-grip 8. To this tubular shaft is affixed the inner end of an actuating-spring 9, of which the outer extremity is attached to a fixed object, such as a pin 10, supported by the frame. Extending through the tubular shaft is a spindle 11, which projects. at its upper end above the plane of the table-top and is provided with a securing-plate 12, fastened to the under side of a peripherallyflanged cover 13, adapted when lowered, as indicated in Fig. 1 and in full lines in Fig. 2, to rest upon the upper surface of the tabletop 1 and cover the objects arranged thereon, such as the table furniture. By means of said spindle, however, the cover is adapted to be elevated to the position indicated in ,dottedlines in Fig. 2, and in order to facilitate this operation the lowerextremity of the spindle 11 is seated in'a socket-bearing 14 in a supporting-plate 15, which is mounted upon guide-rods 16, depending from the under side of the springsupporting-frame,or preferably from the. lowermost plate 4: of said frame. The supporting-plate 15 is provided with suitable guide-openings fitted upon the guiderods 16, and attached to the plate are elevatingcords 17, extending upwardly through the plate 4 and reeled upon spools 18, supported bya spindle 19, which is mounted in the springsupporting-frame. This spindleisprovided near the side of the tableframe with a terminal crank 20, by which motion maybe communicated to the spools to elevate the plate 15, and hence the cover 13, and in order that said spool-spindle may be secured at the desired adjustment to maintain the cover in its elevated position a ratchet mechanism, ineluding a ratchet-wheel 21 and a pawl 22, may

be employed.

Loosely mounted upon the tubular shaft 7 above andcontiguous to the plane of the upper surface of the table-top 1 is a serving-table or dumb-waiter 23, having a ratchet connection with said tubular shaft, such connection in the construction illustrated consisting of a pawl 24:, engaging a ratchet 25, and also loosely mounted upon the shaft 7, preferably below the plane of the spring 9, is a mastergear 26, having a ratchet connection with the shaft, including a pawl 27 and a ratchet-wheel 28. These ratchet connections provide for the manual rotation of the spindle to wind the spring 9 Without affecting either the servingtable or dumbwaiter or the master-gear, whereas the rotary movement of saidtubular shaft when actuated by the spring 9 causes the corresponding rotation of both the dumbwaiter and the master-gear.

Mounted in a bearing in the lower plate 4,

concentric with the spindle 11, is the hub 29 of apinion 30, and a sliding connection is provided between said pinion (which I will refer toin the following description as the driven pinion or gear) and the spindle 11 to provide for the communication of rotary motion from the'pinion to the spindle, while allowing the latter free axial movement or movement parallel with its axis through the pinion. In the construction illustrated the pinion is provided with a key or feather 31, engaging a longitudinal slot 32 in the spindle. The connection between the driving or master gear 26 and the driven gear 30 may consist of a train of gears constructed and proportioned to multiply speed and at the same time reverse the direction of rotation of the table-cover 13 (which is actuated by the spindle 11) from that of the serving-table or dumb-waiter, and in the construction illustrated said train of gears includes a pinion 33, meshing with the master-gear and having upon its spindle 34: a gear 35, which in turn meshes with a pinion 36 and a gear 37 on the spindle 38 of said pinion 36, said gear 37 meshing with the pinion 30. It will be understood, however, that the train of connections between the driving and driven gears maybe varied to suit the relative speeds of rotation of the servingtable and the tabletop; but in practice I prefer to so dispose the members of the train ofgearing as to insure an opposite rotation of said members. The tabletop carries fan-blades 39, preferably having stems 40, which are foldably or hingedly mounted upon the rim or flange of the cover to provide for the folding of the flange parallel with the periphery of the table-cover when the device is not in use or when the cover is lowered.

From the above description it will be seen that when the table-cover is lowered the tablefurniture is protected from dust and insects, whereas by the turning of the operating-crank on the spindle 19 of the spools 18 said cover may be elevated to the desired height to accommodate the persons occupying positions at the table, and that by winding the actuating-spring through the wing-nut S rotary motion in opposite directions may be communicated to the dumb-waiter and the fan, consisting in the construction illustrated of the table-cover and fan-blades carried thereby, to convey dishes on the dumb-waiter to the various occupants of the table and at the same time prevent insects from approaching the table. The fan serves as a governor to prevent the too-rapid movement of the operating mechanism, and thus regulates the speed of rotation of the serving-table or dumb-waiter.

Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of this invention.
