FOLDING TABLE.

Specification of Letters Patent.

Patented May 18, 1909.

Application filed June 3, 1908. Serial No. 436,417.

To all whom it may concern:

Be it known that I, LAWRENCE NOLAN, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Folding Table, of which the following is a full, clear, and exact description.

My invention relates to folding tables, my more particular purpose being to provide a form of knockdown table having great strength combined with lightness.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all thefigures.

Figure 1 is a side elevation showing the table complete, the table comprising two horse and folding boards resting thereupon, these boards being provided with various detachable braces and other strengthening members; Fig. 2 is a fragmentary inverted plan of the table, this View showing the folding boards and also showing the various rods and their connections with the boards and with each other; Fig. 3 is a fragmentary section upon the line 33 of Fig. 2, looking in the direction of the arrow and showing the oppositely disposed clamping plates for holding together the supporting bars, this view further showing a part of the interlocking joint for temporarily connecting the supporting bars together; Fig. 4 is a vertical cross section on the line 41 of Fig. 3, looking in the direction of the arrow, and showing the bolt used for connecting the center braces to the supporting rods in order to support the middle of the table; Fig. 5 is a fragmentary section upon the line 5-5 of Fig. 2, looking in the direction of the arrow, and showing how the supporting bars are connected with the top beams of the horses and also how the supporting bars are connected with the table boards; and Fig. 6 is a fragmentary section upon the line 66 of Fig. 3, looking in the direction of the arrow, and showing the inter locking joint for holding together the two supporting bars, this view further showing how the supporting bars are also bolted together.

A number of

table boards

7, 8, are ar ranged inpairs as indicated in Fig. 2, andfitted edge to edge by dowel pins 9. The various pairs of boards are connected transversely of the table by hinges 10. Thus the table top is made up of a plurality of juxtaposed boards separable on a longitudinal line, while each board consists of sections or members hinged on a transverse line, so that upon 'the boards being separated, the sections of each board may be folded onto each other and the table top thus be brought into a space having a total width and length equal to the width and length of one hinged sec tion. Sup orting legs 1.1, 12, are arranged in pairs and are provided with

top beams

13, 14, so as to form supporting horses which may be of any suitable construction. Supporting

bars

15, 16, are arranged in overlapping pairs as best indicated in Figs. 2 and 6, said supporting bars having a general tapered form as seen best in Fig. 1, and being disposed longitudinally of the table, one supporting bar ranging approximately along the center of a board 7 or S and crossing the transverse line on which the board sections are hinged. Mounted upon the outer or smaller end of each supporting bar 15 is a clip 17 preferably of sheet metal formed with. an approximately U-shaped end portion 18 to fit over a

top beam

13 or 14 of a horse. On the top of the clip 17 is an upwardly extending spur 19, see Fig. 5, which is adapted to enter a table board and serves to fix the latter on the supporting bar as well as resulting in relieving the clip from the longitudinal strain which might tend to distort its U- shaped portion. A second clip 20 has a turned end 21 and is secured to a supporting bar as best illustrated in Fig. 5 in a position preferably overlying the shank of the clip 17 so as to coact with the U-shaped portion of said clip to retain the supporting bar in engagement with. the horse. A clamping plate 23 is let into the top surface of each table board section and its a corresponding recess therein, so as to cross the transverse line on which the board sections are hinged. The clamping plate 23 is provided with vertical bolts 24 one bolt being disposed at each. side of the transverse hinge line. The said bolts extend downward through the table board sections and through the supporting bars, being received in semi-circular recesses 15*, 16, formed in the opposite faces of the over lapped portions of the supporting bars; said recesses when the supporting bars are in proper position form bolt-holes.

Thumb nuts 26 are revolubly mounted upon the threaded. portions 25. Another clamping plate 27 is adapted to fit against the lower edges of the supporting

bars

15, 16,"and is made of a width corresponding substantially to the aggregate thickness of the supporting bars, as will be understood from Fig. 4. The clamping plate 27 is provided with upturned ears 28, each fitting respectively one end of a supporting bar (see Fig. 3).

When the clamping plates -3, 27 are in position and the thumb nuts 26 are tightened upon the bolts 24, the supporting bars and the table boards are forced tightly together. A pair of flat metal bars 29, each serving as a brace, are crossed as indicated in 2, and connect together adjoining clamping plates 27; These bars 29 are provided with holes which are slipped over the threaded portion before the thumb nuts are forced into position. The thumb nuts being tightened, the bars 29 effectively brace the supporting bars upon one part of the table relatively to those upon another part.

Mounted upon. the

sup bars

15, 16 and embedded therein are

metallic plates

30, 31. These metallic plates are secured to the supporting bars by aid of

screws

32, 33. The plate 31 is provided with a hook 34 and with slots 35, 36. The plate 30 is provided with a slot 37, and underlying'this slot is a longer slot 38 in the supporting bar 15. The supporting bar 16 adiacent to the slots 35, 36 is provided. with longer slots 39, 41). Mounted upon the plate 30 are

hooks

41, 42, which may extend into the

slots

39, 40, the hook 34 upon the plate 31 meanwhile e):- tending into the slot This enables the two supporting bars to be locked together, the

plates

30, 31 with their various hooks and slots together serving as an interlocking joint, as will be understood from Fig. 6. Dowel pins 30 on one supporting

bar section

15 or 16 are received in longitudinal slots 30 in the companion section to further hold the supporting bars in position, said pins being located. at opposite sides of the

interlocking plates

30, 31, near opposite ends of said plates and serving to protect the

hooks

34, 41, 42, against any wrenching strain to which they may be subjected, since the pins act to resist a careless movement tending to swing the sections 1.5, 16 on the clamping bolt 47 next to be referred to. The sections or

bars

15, 16, composing each supporting bar are united and clamped by a horizontal bolt 47 having a binding nut 43 and one of the sections, 15 for instance, see particularly Fig. 6, is formed with a slot 49 whereby when a nut 48 is loosened sufficiently the

members

15, 16, can be moved longitudinally with respect to each other and then given a lateral movement flatwise toward or from each other in the direction of the axis of the bolt 47 for engaging or dis engaging the

hooks

34, 41 and 42 of the plate 31 with the corresponding

slotted portions

38, 39, 40. With the nut 48 loosened sufficiently and without entirely removing it, the

sections

15, 16 after the described longitudinal and lateral separating movements may be swung around with the bolt 47 as a pivot and thus swung onto one another to occupy a small space. The bolts 47 are preferably located at. such a point on the supporting

bars

15, 16, that the said bolt in each pair of supporting bars will come directly under and parallel with the transverse hinge line of

boards

7, 8 and I utilize said bolts to secure apair of attachable central supporting legs so that the latter will thus be on the hinge line of the boards. One of said legs is shown, see 1, and preferably consists of telescoping sections 43, '44, that are tobe clamped together in a given adjustment by a binding screw 45. The upper end of the upper section, 43, is-flattened and slotted to form a fork 46, which may be readily passed over a bolt 47 and be tightly clamped by the nut 48.

lv'y improved devices are used as follows: In order to assemble the parts, the boards 7,

8 are fitted together by aid of the dowel pins 9 and. arranged as indicated in F 2. The supporting

bars

15, 16 are next arranged in pa1rs, each pair being held together byabolt 47. Each pair of supporting bars are first put together loosely, as indicated in Fig. 6, the hooks 34 entering the slot 38, and the

hooks

41, 42 entering the

slots

39, 40. .lhe supporting bars are then pulled endwise so as to move the bar 16 to the right and the bar 15 to the left. The hooks thus grip under the adjoining edges of the

plates

30, 31 and hold the supporting bars firmlytonether. The bolts 24 are 116KB inserted and further tend to prevent the bars becoming dislodged relatively to each other. The

damping plates

23, 27 carry the purpose still further and also prevent the possibility 'of the supporting bars being displaced relatively to ach other in a direction corresponding to the general longitudinal direc 'l'he horses are next tion of the bolts 24. set up and the clips 17 are secured thereupon by slipping the U-shaped portions 18 over them, the clips 20 being sprung slightly downward according to F 5 and passed around. the U-shaped portions 18. 'l he

boards

7, 8 are neXt forced down upon the spikes 19. 'i he tubular sections 43, 44 are next mounted in position by securing the fork 46 by pressure of the thumb nut 48. The sections 43, 44 together constitute a central bracing member for holding the table at its middle, as will be understood from Fig. 1. In order to take the construction apart the

thumb nuts

26, 48 are loosened and the various parts removed in the order reverse to that above described for purposes of assembling.
