SECTIONAL TABLE.

Specification iiatentcd Aug. 8, 1922.

Application filed April 28, 1920. Serial No. 377,238.

To all whom it may concern:

Be it known that I, l hinrnn A. Aniiiis, of Rochester, in the county of Monroe, in the State of New York, have invented new and useful Improvements in Eiectional Tables, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to certain improvements in sectional tables. I

More specifically the invention pertains particularly to the construction of a standard frame section adapted-to be combined with similar sections arranged either laterally or longitudinally or both with respect to the first section to form a table of desired size capable of being rapidly and easily assembled and disassembled, and capable of being enlarged by the addition of similar sections at any time.

A further object relates to the construction of a clamping member for securing the connecting strips or boards to respective longitudinally arranged frame sections to provide a connecting means for the sections as well as a shelf for use if desired.

Other objects and advantages relate to the details of construction of the parts of the table as will more fully appear from the following description taken in connection with the accompanying drawings in which Figure 1 is a perspective view of a standard frame section with a clamping member used for an. intermediate section assembled therewith.

Figure 2 is a similar view showing a clamping member. for an end section assembled with. a standard frame section.

Figure 3 is a perspective view of an intermediate clmnping member.

Figure l is a perspective view of an end clamping member.

Figure 5 is a cross section on line'55, F i gure 4.

Figure 6 is a cross section on line 6-6, igure 4.

Figure Figure 3.

Figure 8 is a cross section on line 8-8,

Figure 3.

Figure 9 is a vertical section through two standard frame sections arranged laterally end to end and secured together in the manner provided and having a suitableconnecting top embodying a central partition.

As shown, the invention comprises a 7 is a cross section on line 7 7,

standard frame section l mounted upon bases or pedestals 4 in an adjustable manner, as by means of bolts -3 and slots formed in the bases to permit limited variation in the height of the resultant table.

The frame ---lconsists of vertical up rights -5 and 6, and upper and lower cross walls -7- and 8 respectively. ihe cross walls may, as shown, be formed with flanges --9 and 10 respectively, some of which may be formed with opensided slots for the reception of screws or other attaching means in the connecting bars -11 or the top parts -l2.

Preferably the frame parts are "if-shaped in cross section throughout with the base of the T extending downwardly from the cross walls and --8- and inwardly from the vertical uprights or posts 5 and 6.

One post, as --5, may be formed with an enlargement 13 forming the reinforced part permitting the formation of a bolt opening l l through which the bolt l5 may extend when two of the frame parts are arranged laterally end to end.

l Vhen so arranged, as shown in Figure 9, the top plates or boards -l2- areformed with flanges -16 adapted to be seated in grooves in the opposite side of a central partition l? which partition is thus sup ported in operative position when the top plates are secured to the frame sections. The cross wall 8 may be formedwith a series of enlargements -1S constituting reinforced parts permitting the formation of vertical bolt openings for the purpose of securin g clamping bars 19- in proper position relatively to the frame section to grip the oppositely extending connecting members or boards 11-.

A- minimum of two frame sections is required, spaced by a suitable top 12 and suitable connecting boards 1l-- for the formation of a complete table. Any number of sections and essential parts may thereafter be added to form a table of the desired length, and by duplication of this arrangement a table of double width may be formed. The connecting members or boards 1lare of a suitable length so as to extend between the frame sections 1 and terminate at substantially the central portion of the respective cross-bars or walls 8 and where the table is to be formed of three sections longitudinally arranged,

the intermediate section is provided with the in; member as shown in Figure 4:.

lhe clamping member of Figure 3 comprises an elongated substantially flat strip -20 having each of its ends formed in a yoke 21, each yoke adapted to receive one of the vertical uprights 5 or -6 respectively so that the clamping member may slide vertically along the uprights and for this purpose vthe yoke parts are widened vertically so as to extend above the flat plate-like portion 20.

Extending from, the opposite side of the strip.20-is a series of box-like structures 22' formed by connected flanges projecting downwardly from the side plate and spaced apart a s'uflicient distance to receive between them the connecting bars The plate *20- is further provided with downwardly projecting flanges extending between and connecting the box-like structures -22-, the two flanges adjacent the ends of the flattened strip -20 terminating at the base of the opening in the yokes 21-.

It will be vunderstood from the drawings and this description that the ends of the connecting bars -1-1 rest upon the cross walls -8-' and that the ends of the connecting bars abut against the flanges -23 Bolts 50 are then passed through the openingsin'the reinforced parts --'l8 through thexbox-like structures -22- and openings -24 inthe plate -20- and by the use of. suitable nuts the parts are drawntightly together to-grip. the connecting bars '11- and holdthem rigidly in position. In order to' effec t this -more positively, particular-lyin connection with connecting bars'of slightly varying thickness, the plate --20 is provided with V-shaped tangs'25 intermediate theboxdike portions which are adapted "to be pressed into the connecting bars to make the engagement more rigid and permanent.

It will be noted that the end-clamping members -26- should be formed to receive connecting bars -l1-- only upon oneside of the flanges 23 and for the purpose of covering the ends of the connecting bars and portions ofthe cross-walls -8 the endclamping bar -2t3 is formed with a laterally extending part -27-- forming a continuance of theplate -20 and provided with a pair of longitudinally extending flanges substantially parallel with the flanges ---'23 and extending below the flanges 23--, the inner flanges 28 resting upon the prorjectiojns lO-- and reinforcing the box-like structures 22 and the outer flanges 29-'-' forming an end-covering for the parts. I

The flanges --1.0- may form receiving and modifications in the details of form and construction may be made without departing from the spiritof this invention as set forth in-theappended claims.

What I claim is 2 v I 1. The combination with a frame coin-prising spaced uprights and connecting cross bars of apcl-amping member having its 0pposite ends bifurcated and slidably mounted on respective uprights and its intermediate portion formed with a series of depending boxlike structures spacedby depending longitudinally extending flanges and-means for securing the clamping member to one of the crossgbars. a The combination with a frame compris ing spaced uprights and cross bars extend: ing between the uprights of a clamping member having. itsopposite ends-slidably mounted on respective uprights and its intermediate portion formed with a seriesof depending spaced box-like structures and means for securingthe clamping membert one of the cross bars. r e

3. The combination with a frame compris ing spaced uprights and a cross bar connecting the uprights of a clamping member t adapted to engage'the crossbar andforfmed with a series of depending latitudinally extending flanges and longitudinally extending flanges connecting the said latitudinally extending flanges. p

4. In a knock-down tahle'a rigid rectangular frame comprising a pair of uprights and connecting cross bars, aclamping member having its'opposite ends bifurcated for slidable engagement with said uprights respectively,'and 1ts lnterlnediate 'portlon formed with a series of projecting'box-lik'e structures insubstantial contact with one of said crossbars and means for securlng the clamping member vto thecrossibar.

In witness whereof I have hereunto set my hand this 6th day of March,1920. l
