DRAWING-TABLE.

SPECIFICATION forming part of Letters Patent No. 778,872, dated January 3, 1905.

Application filed December 9, 1903. Serial No. 184,372.

To all whom, it may concern:

Be it known that I, Josnrn D. LUGOSOH, a citizen of the Empire of Germany, residing in West Hoboken, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Drawing- Tables, of which the following is a specification. 7

This invention relates to an improved drawing-table for the use of architectural, mechanical, and other draftsmen, which has the advantage that the top of the drawing-table can be readily adjusted to any desired inclination to the horizontal, and the further advantage that the rolls of drawing-paper, tracing-linen, &c.',can be stored below the table and stretched over the surface of the top, so as' to be conveniently shifted over the same and cut off when the detail and other drawings are finished, producing thereby considerable saving in the drawing-paper, tracing-linen, &c., used, as not the least waste is incurred thereby; and the invention consists of a drawing-table comprising an upright supporting-frame, a top hinged to the front end of the frame, means upon the frame for supporting a number of rolls of drawing-paper, &c., and slots in the said tops near'the front and rear edges of the same for guiding and stretching said drawingpaper, tracing-linen, 860., over the board; and the invention consists, further, of specific means for supporting the rolls for the drawingpaper, tracing-linen, &c., all of which will be fully described hereinafter, and finally pointed out in the claims.

In the accompanying drawings, Figure l is a side elevation of my improved drawingtable; and Fig. 2 is a vertical longitudinal section of the same, showing the top of the table supported in inclined position.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, A represents the upright supporting-frame of my improved drawing-table. The frame A can be made of any suitable size, according to the work to be done, whether the same is architectural or mechanical work, shop-drawings, &c. The supporting-frame A is made of rectangular shape and providedat one side with trans verse braces a a and at the opposite side with a lower brace (0 that is hinged to the cornerpost at its rear end and locked by a bolt (Z at its front end, and a second brace 0*, that is hinged at both ends to the corner supportingposts of the frame, as shown clearly in Fig. 1. The braces a and a are provided with journal-bearings for receiving the core ends of the rolls ofdrawing-paper, tracing-linen,&c. One or more rolls may be supported on said braces, as desired. The hinged braces serve for the purpose of permitting the opening of the supporting-frame at one end, so as to permit the insertion of the core R of the rolls into the corresponding journal-bearings of the stationary braces a a and into the journal-bearings of the hinged braces after the same are placed in position on the supporting-frame. A handle n may be attached to the core end of large rolls, if desired, so as to permit the turning of the roll on its axis.

The top B of the drawing-table is hinged at its under side near its front end to the front end of the supporting-frame A. It rests on the top portion of the supporting-frame when in horizontal position, as shown in Fig. 1. When it is desired to place the top at any suitable angle of inclination to the upper end of the supporting frame, it is raised by the draftsman to the required position. At the under side of the top, at both sides of the same, are arranged stationary racks a, which are engaged by pivoted arms f, that are ac tuated by means of stout wire springs h, the free end of which is placed into the grooved back of the braces, while the opposite ends are attached stationarily to the upper part of the supporting-frame A, as shown in Fig. 2,

the same when the hand-wheels are turned.

This permits the ready lowering of the arms after the racks have been released from the ends of the same by a slight lifting action by the turning of one of the hand-wheels g of the shaft and the winding up of the connecting-wires or gut strings g, so that the braces e are returned into the top part of the supporting-frame and held in this position by the lowering of the top B, as shown in Fig. 1. The turning of the shaft causes the simultaneous lowering of the arms, as both connecting-wires are attached to the opposite ends of the same shaft. The springs actuating the arms cause also the simultaneous raising of the arms in following the upward motion of the top when the same is adjusted at inclined position. The shaft g being free to rotate will permit the wires to follow the upward motion of the arms, the springs being made strong enough to produce this result, so that the automatic supporting of the top by the arms in inclined position is obtained,

The top B is provided near its front and rear ends with transverse slots S and S, of suflicient width to permit several layers of paper, tracing-linen, &c., to pass through said slots and be stretched over the top B and passed through the slot at the rear end, as indicated in Fig. 2. This permits, first, the stretching of the ordinary drawing-paper over the top B. When the drawing is finished, the tracing-linen is passed through the lower front slot and stretched over the paper on the board and down through the rear slot, so as to permit the direct tracing from the drawing on the board. Sometimes it is desirable to stretch several layers over the boardsuch as drafting-paper for shop-drawings, tracing-linen and use either one as required, the covering layer being removed if necessary-by winding it up on the corresponding roll. When the drawing-paper or tracing-linen is cut off from the board, the next length of drawing-paper is stretched over the board and retained by the front and rear slots, so that thereby only so much paper as is required for the drawings on hand is used, whereby the waste of material that is caused by the present mode, by cutting off sizes at random, more or less, from the rolls, is obviated, while the paper is always stored in a handy and convenient position for the use of the draftsman, whereby it is preserved in better shape and condition than when stored away in closets, &c. In some cases it may be desirable to stretch the drawing-paper through the rear slot forward over the top and then through the front slot, which may be done with the same facility as when stretching in the ordinary manner from the front toward the rear slot.

The core of the roll of tracing-linen may be supported on the upperbraces a and a of the frame A, while the core of the roll of drawing-paper is supported in the lower braces a in such a manner that the drawing-paper is guided by and moved over the roll of tracinglinen above the same, as shown in'Fig. 1.

My improved drawing-table has the following advantages: first, that its top can be adjusted to any inclination as required bythe work in hand; second, that it can be returned to horizontal position on the supporting-frame by the simultaneous return ofthe arms into lower position in the supporting frame; third, that the convenient storage of the drawing-paper, tracing-linen, 8:10., in the supporting-frame of the table is obtained, and,fourth, that considerable economy in expensive drawing-paper, tracing-linen, &c., is produced, as only as much as is necessary for the work in hand is cut off after the same is completed, so that no waste is incurred, the paper required for use being always held in stretched position on the top of the drawing-table and moved forward over the top, as required by the size of the architectural or other drawings that are to be made thereon until the completed draw ing or tracing is finally out off.

Having thus described my invention, Iclaim as new and desire to secure by Letters Patent 1. In a drawing table, the combination, with an upright supporting-frame, and rolls of paper carried thereby, of a top hinged to the front edge of said frame and provided with transverse slots near the front and rear ends thereof for stretching said drawing paper from the rolls through said slots over said top, and means for adjusting said top to different degrees of inclination on said supportingframe.

2. In a drawing-table, the combination, with a supporting-frame provided with bracing-pieces at one side and hinged braces at the opposite side, the side braces being provided with journal-bearings, and rolls of drawingpaper, tracing-linen, &c., the cores of which are journaled in said bearings, the hinged braces permitting the convenient insertion of the rolls.

In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.

JOSEPH D. LUGOSCH.
