The invention relates to a drafting table. The drafting table to which the invention applies in particular has a'pivoted table top supported on legs arranged in pairs at each relative to the other pair to adjust the legsl end.
An object of the invention is to provideV a drafting table which is readily adjusted to the floor to keep the table from tilting.
Another object is to provide a table which is rigidly braced in a forward and rearward direction and endwise.
Another object is to provide the table with a tabletop which is braced against torsional c stresses to prevent distortion of the table top by lwarping or twisting.
Another object is to provide a table with a table top which may be readily adjusted in either a vertical' or horizontal position.
Another object is to :provide a table which may be readily assembled or disassembled.
Another Objectis to provide a table which is simple in construction.
Another object is to' provide a table which may be economically manufactured.
According to the invention as ordinarily embodied in practice, the table is provided with legs pivoted in pairs at each end to permit each pairs of legs to turn or oscillate to the iioor andkeep the table from tilting.
The invention is embodied in the accompanying drawings in which the views" are as follows:
Fig. l isan elevational view of the table. Fig. 2 is a partial elevational view, on an enlarged scale, of the pivoted connection between the table top and the legs.
Fig. 3 is a sectional view on the line {5*3,
Fig.
Fig. 4 is an end view of the table.
Fig. 5 is an end view of a table showing the legs in a modified form.
The table top l has fastened on its under side cross-braces or cleats 2, and fastened to alternate cleats are brackets 3.
The brackets are arranged on an elongated tubular bar 4 extending endwise of the table, and each bracket has a clamping ring 5 held by a screw 6, by which the bracket is normally kept rigidly clamped to the bar.
The'bar is of suiiicient diameter to have torsional rigidity, and when the brackets are clamped in fixed position upon the bar, the table top is braced by the b-rackets and the b ar againststresses in substantially all directions to prevent distortion of the ta-ble to by warping or; twisting.
AThe table has its legs arranged in pairs' at each end7 each pair being Vspread'at the bottom and converging towardthe top to brace thetable ina forward and. rearward direction, and having a suitable tie-rod 7 to provide rigidity in each pair;
Each leg is formed by struts 8 spaced apart at the top and converging toward the bottom to brace the tablecndwise, the struts being prevented from vspreading by suitable tie'- rods 9.
Formed at theapeX of each pair of legs are two axially spaced clamping rings l0 and l1 by whichea'ch pair is pivoted to the bart to turn oroscillate relative tothe other pair and thereby all they legs are brought into bearing upon the lioor.
One of the clamping ringsIO is' held by a screw l2 to have a yielding' fr'ictional'grip upon the bar 4.1 to allow the' tabl'e top l to be adjustably tilted, and the other clamping ring Il is held by a screw-bolt 13 provided with a handle la tofirmly grip the bar and keep the table top in a liXed position.
The table may be readily disassembled for which bea-rs uponV and is connected to the rearleg 17 at its upper end.
.The invention is susceptible. of various modifications Without departingv from the scopethereof, as hereinafter claimed.
The invention is hereby claimed as follows :v

5. A table, comprising atable top, a longi- "tudinal bar, brackets secured to said table top on the under side thereof and connected by said bar to brace the table top against stresses in substantially all directions, a pair of legs arranged at each end of said table top and pivotally connected thereto to permit each pair to turn relative to the other pair to adjust the legs to the floor, each leg being formed by struts spaced apart kat the top and converging toward the bottom to brace the table endwise, means to yieldingly` clamp said table top against movement to permit said table top t0 be adjustably tilted, and means to lock said table top in a fixed position.
6. A table, comprising a table top, a longitudinal bar, brackets secured to said table top on the under side thereof and connected by said bar to brace the table top against torsional stresses in substantially all directions, a pair of legs arranged at each end of A' said table top and pivotally connected thereto to permit each pair to turn or pivot on a horizontal aXis and relative to the other pair to adjust the legs to the floor, each leg being formed by struts spaced apart at the top and table vas they approach the top to brace it against end thrusts'andtransversely of the table top as they approach the bottom to brace it on ailoor, and means for setting the table top in different angular positions relative to the horizontal.
8. A drafting table comprisinga tabletop, a.k plurality of bearing brackets 'depending from the table top,'a bar rotatably mounted in the brackets, legs for supporting the bar, rings provided on each leg in which the bar may be rotatably mounted, the rings on each leg being spaced longitudinally of the bar to brace it against endwise thrusts, thelegs diverging transversely of the table top from the bar toward thebottom adapting them to seat firmly on any foundation, and means for setting the table top bar and legs in different predetermined relative positions.
9. A drafting table comprising atable top,l a plurality of cleats extendingtransversely ofthe table top, bearing brackets depending from alternate cleats, a bar rotatably mounted in the bearing brackets,.the bar and cleats serving to brace the table against torsional stresses in substantially all directions, the legs diverging outwardly longitudinally of the bar from the bottom upwardly, rings'p'rovided on the diverging legs to receive the bar,
