' 'SPECIFICATION farming part of Letters Patent No. scarse, dated May 1v, 18er.
`Application led October 1l, 1886.
To all whom it may concern,.- I
'Be it known that I, THOMAS W. MANN a citizen of the United States, residing at Hol'- Massachusetts, have invented new and useful Improvements-in Drawing-Tables, of which Thisinvention relates to improvements in Vdrawing-tables for the use of 'draftsmen, and particularly for architects, surveyors,` and and the invention consists in the construction and arrangement of the various parts of the table, as hereinafter fully described, and set forth in the claims. i l
In the drawings,'forming part of this specification, Figure 1 is a side elevation, partly in section,of a drawing-table constructed according to my invention. Fig. 2 is a perspective View of the table Showing a portion of one the apron and the sides and the end covering removed and a portion of the apron table 'one corner of the table. Figs. 4, 5, 6, and 7 referred to and fully described.
In the drawings, A is the table, which 'is pivotally supported on two standards, B, -one the table, as shown in Figs. 1 and 2, the lower ends of the standards being lbraced and held in proper position by suitable transverse rods, 2. The ends f a transverse shaft, 3, have their bearings in the upper ends of said standards B, and on each end of saidshaft is screwed a 1111134. f
The table A consists of two rectangular frames, 5, preferably of Iwoodheach attached totwoj arms, 6, one on the upper andv one on the lower side of the latter, as shown,'whereby they are "both supported in parallel planes and` sufficiently separated one from thelother to permit of. hanging an apron-roller, 7, therebetween at the opposite ends Aof the table, and the ends-of saidshaft 3 pass through said arms,
contiguous to the inner sides of the upper ends of the standards B. That part of the inner which surrounds the bearing of the shaft 3 is,`
Serial No. 215,869. (b l'o modeLlr provided with a series of radiating corruga-v tions, c, as shown in Fig. 6; and, as Shown in Fig. 5, the side of the arm 6, adjoining the said corrugated side of the standard B, is provided with like corrugations d, and the latter vand,those on the standard are adapted to engage with each other when the nut 4 is screwed against the side of the standard, and hold the table ina level or in an inclined position, as.
maybe most desirable or convenient for drawing.
0n the Surface of the upper borders of the u table A are made a series of gradnations or angle-indicating lines, as Shown in Figs. 2 and 3, as may be desirable to assist in obtaining scalemeasurements and desired angles on drawings. The vsaid arms 6 are made, preferably. of metal, and at one end thereof are formed suitable boxes or bearings, 8, which receive the endslof the shaft of one of said apronrollers 7 and the shaft of the apron-roller at the opposite end of the table has its bearings inslots 9 in the ends of said arms, to provide d for adjusting the roller in which said shaft is toward and from the roller at the opposite end of the table, in order -to impart the proper tension to the below-described apron. The said -adj ustable roller 7 is given .the requisite movement in the'table for. the aforesaid object bya screw,12, which passes through a nut, 11, on each arm 6,- (see Fig. 7,) the end of said screw having a swivel-connection vwith a yoke, 10, on
each end of the shaft of said roller'near the inner side of the arms 6, the shaft of said roller having afree rotary movement in said collars.
The opposite sides of the drawing-table consist of a panel-likev construction, 13, of wood or other suitable material, the edges of which are let into grooves 14 in the inner opposite edges of said frames 5, as shown in Fig. 2, whereby said panels are' properly supported in a plane with the periphery of the rollers? at eachend of said frames. The said panels 13 constitute a support between the rollers 'on the sides of the drawing-table for that part of the apron 15between the rollers 7, at each end of the table. A metallic strip,` 16, is secured across each end of each of said frames 5, one edge ofwhich projectssomewhat over the adjoining surface fof said apron, forming a narrow projection ower that portion of the latter IOO which nesagaint the mns 7, substantially in proper' position and covers the panels 13.1011 each side of the` l dra'wing-table, and is capable of being moved on xo sideV thereol` to view on eitherside of the table, thereby providing for attaching-to the apron which may exj `1. ,A drawing-table having a roller at oppofrom Fig. 2, showing the opening between `the 3o drawing-table A is pivotally supported by the The apron .15 `is' an material, Vintoiwhich l.less apron, which constitutes in effect a draw-V varchitectural and civil-engineering lconstrucin place in anyY other suitable manner. The

The said apron is"secu red around the rollers 7,1
may
said rollers to bring any portion of the outer4 large pieces of drawing-paper, Atend entirely over the Ysurface of saidapron'; or
several small sheets of drawing-paper may be secured thereto, as may bedesi'rable in the production of fa' large or of several small draw- The above'described drawing-table, however, provided, asdescri1bed,`with the said ending-board having more than twice the supericial surface of one side of a drawing-table, possesses peculiar advantages for delineating on alarge scale and on one sheet illustrations of tions-.not afforded by drawing-tables of the ordinaryclass. One of said'strips, 16, is omitted roll and the adjoining end of frame @which is covered by it. s f
The height of the standards B,',on which the shaft 3, is such as to permit of swinging said table from a horizontal position, as shown in Fig. 1, to a vertical one, or to any angle between those two positions, thereby makingfit very convenient to bring the surface of the table to any desired position, either for the draftsman or for the exhibition of any figures that may be drawn upon paper, which is secured to the sides of the table.
The ends and edges of the drawing table are incased by the covers 17 and 18, of metal or thin wood, as may be preferred, whose edges are secured in grooves in the frames 5, asfshown in Fig. 3-that is to say, the edges of the cover 1S are so sceared, and the cover 17 is attached to the ein? of the said cover 18, or is securedv the usual drawing-tacksv or elsewherelmng one provided with Yrollers,
'i y pesante or lesstensiontothe apron 13, project through said end covering, 17, as shown'.` L I am aware' that t isA not new to construct drawing-tables having rollcrs on their ends,
thereon, onI `which the ,two ends of asmple sheet or copy are wound, nor each `h avinga piece of cloth nu it to be connected' to the ends of a v'sheet of drawing-paper, whereby the latter is held ina distend-edposition on the table; and I do not claim said constructions; but
W'hat I claim as my invention is site ends thereof, and the panels 13 on oppo- .site sides of the table, whose surfaces are substantially in a plane with ythe peripheries of said rollers, combined with an en 15, extending around thetahle and supported on said rollers and on one er both of said panels, capable of having drawingpaper attached to its surface, substantially as set forth.
