ADJUSTABLE FOLDING TABLE.

SPECIFICATION forming part of Letters Patent No. 646,152, dated March 27, 1900.

Application filed November 2, 1899- Serial No. 735,602. (No model.)

To all whom it may concern.-

Be it known that I, HENRY MEHSERLE, a citizen of the United States, and a resident of Rochester, in the county of Monroe and State of New York, have invented a new and useful Improvement in Adjustable Folding Tables, which improvement is fully set forth in the following specification and shown in the accompanying drawings.

My invention is an adjustable folding table designed more particularly to be used at the side of a bed in the sick-room, in hospitals, or other places. It is also designed for other uses to which it may be found adapted, as in writing, for the playing of games, &c. The table is constructed to have the top raised or lowered to different positions of elevation, to be tilted on a horizontal axis, to be swung laterally from a center at one side of the top, or to have a swivel motion upon a center within it to cause it to assume Various positions relative with the supporting parts.

The invention is hereinafter fully described, and more particularly pointed out in the claims.

Referring to the drawings, Figure 1 is a side elevation of the table, showing the top in two positions of elevation by full and dotted lines. Fig. 2-is a front elevation (seen as indicated by arrow 2 in Fig. 1) showing by full and dotted lines the top in various positions as to horizontality. Fig.3 is a plan of the device, showing the top occupying various positions in lateral adjustment by full and dotted lines. Fig. 4 is a plan showing by full and dotted lines different positions of the top resulting from a swivel motion. Fig. 5 is a side sectional elevation of parts at the top of the spindle, parts being shown in two positions by full and dotted lines. Fig. 6 is a similar elevation at the lower part of the standard, parts being shown in two positions by full and dotted lines. Fig. 7 is a front elevation of parts, (seen as indicated in arrow 7 in Fig. 6,) parts being broken away. Fig. 8 is a front elevation of parts, (seen as indicated by arrow 8 in Fig. 5,) parts being omitted and broken away. Fig. 9 is a front elevation of the clamping device, (seen as indicated by arrow 9 in Fig. 1,) the carrying-arm being transversely sectioned on the dotted line at the point of the arrow.

full size.

A is the top of the table, which is preferably made of wood.

B is a hollow metal standardbranched at its lower end into feet a a.

C are diverging supporting-legs joined at their upper ends and pivoted to the standard 13 at 12, Figs. 1, 6, and 7.

D is a vertical shaft or spindle held by the standard, it being incased in a tube or simple protector c, occupying the hollow of the standard.

E, Figs. 1, 3, 5, and 8, is a divided or hollow head seated at the top of the spindle and adapted to turn horizontally thereon. V

F, Figs. 1, 4, and 5, is a carrying-arm for the top A of the table, formed with a head d to enter the divided head E. l

G, Figs. 1, 4, and 9, is a clamping device for the top A upon the carrying-arm F. p

g, Figs. 1, 2, and 4, is a swivel-bearing for the outer end of the carrying-arm F, secured by means of a holder 2" to the under side of the top A.

The spindle D is adapted to slide vertically in the standard B to raise or lower the table, as indicated in Fig. 1. The spindle issecured to place in its vertical adjustments by means of a clamping-handle h, threaded in the standard and bearing at its inner end against the spindle. The spindle is prevented from turning in the standard by being formed with a fiat side 2', Figs. 8 and 10, to meet a corresponding inwardly-projecting part k of the standard. The head E being adapted to turn upon the spindle enables the top A to be swung laterally to the right or to the left on the spindle as a center, as indicated by dotted positions in Fig. 3, there being a screw clamp 1 provided to secure the head E in its various positions of horizontal adjustment.

The carrying-arm F is held to turn vertically in the divided head E upon a horizontal pin 0, threaded in the head, by means of which the top may either occupy a horizontal position or-be folded down by the side of the standard. This arm F is formed'with a seat a near the head (1 for the clamp G, the latter being adapted to turn upon the seat. The bearing g under the top of the table is formed to turn on the arm F, and the holder 2" for the 'bearing is adapted to have a swivel motion thereon, so that the top A is adapted to both tilt on the arm F and turn as with a swivel motion on the bearing g. In making the swivel motions the top slides through the clamp G, its rear end 19 being made circular and concentric with the axis of the swivel for the purpose. The clamp G is formed of a split or divided part 8, Fig. 9, to engage the arm F, and a part if to engage the top A of the table. The part tis the upper jaw of the clamp coacting with the jaw o to press the top between them. This part 25 occupies a seat or cavity a in the upper side of the clamp, and a tightening-screw r, passing through both parts t and 8, serves to tighten the clamp simultaneously on the arm F and on the top A of the table, thus holding the latter in any of its tilted or swivel positions.

The inner end or surface z of the head 01 of the supporting-arm F is made inclined, as shown in Fig. 5, against which an inclined block 6 is adapted to bear. This block is controlled by a push-rod f, extending downward through the head E, said block being adapted to slide in vertical directions in a cavity 10 in the head. A springm on the push-rod, seated at its lower end in a cavity 70 in the head E, tends to hold the push-rod normally to place, the block 6 being at the lower end of said face .2 of the head 01, as shown in the figure. At its upper end the face meets a shoulder x of the head E when the supporting-arm F is horizontal, its head (1 then having an upper and a lowerbearinge and at, respectively, and a bearing upon the pin 0, which together make said arm stable in its position. When it is desired to fold the top A or let it swing downward parallel with the standard 13, the rod f is pressed downward to the position shown by dotted lines in Fig. 5. This permits the arm F, with the top A, to drop to a vertical position, as indicated by dotted lines, the arm turning upon the pin 0. As these parts swing down the spring on raises the block e to its original position. (Shown in full lines.) \Vhen it is desired to again raise the top A, the block e is pushed downward as before, and as the top reaches its horizontal position, the corner Z of the head at clearing the block, the block will be raised by the spring to its normal po sition back of the head d, as shown in full lines. The lower face y of the head d forms a right angle with the face .2 and it is at the same distance from the pin 0, so that when the arm F is turned down, as stated, the face y will occupy the place just left by the face 2, the block e coacting similarly with both faces.

As shown in Figs. 1, 6, and 7, the head 0 of the legs 0 is held between parallel vertical walls 7t at, projecting from the standard 13,

the pivot b passing horizontally through both, as shown. The inner face a of the head 0 is made inclined, and an inclined block b is provided to coact therewith. This block is adapted to move vertically in a cavity m in the standard B and is controlled by a pushrod 61-, extending upward through a ledge e of the standard, a spring f being provided for the rod. Then the legs 0 are down against the floor, as shown in Figs. 1, 2, and G, the block Z) will be in the position shown in full lines in the latter figure, bearing against the face a, above the pivot-pin b. This serves to lock the legs in the position shown. When it is desired to fold the legs or turn them upward parallel with the standard B, as indicated by dotted lines in Fig. 6, the rod 61 is pushed upward (most conveniently with the foot) to the upper dotted position shown. This clears the upper corner h of the head, allowing the legs to be turned upon the pin 1), as stated.

The upper face g of the head 0 forms an acute angle with the face a, and it is given such a slant that when the legs 0 are turned upward it.- will be parallel with the plane of the slant-face of the block b; but the distance of the face 9 from the pin b is made less than the distance between said pin and the face a, which allows the block b to descend to the lower position. (Shown by dotted lines in Fig. 6.) This causes the block to bear against the face g below the pin b, which serves to lock the legs in their folded position. To turn the legs down again, the push-rod is again raised to carry the block to its upper position. (Shown in dotted lines.) This allows the upper corner hof the head to clear the block, and when the legs reach the floor the block will be again brought down by the spring to the position shown by full lines, again locking the legs in their position of use. The legs when'in their folded position are adjacent to the part c of the standard B, they being between the folded top A and the standard.

The top board or top A of the table makes its lateral swinging motions (shown in Fig. 3) upon a centerD without its limits or periphery and its swivel motions (shown in Fig. 4) upon a center within its periphery.
