DRAWING-BOARD HOLDER.

Specification of Letters Patent. Patentgd act, 22, 1918,

Application filed February 8, 1916. Serial N 0. 77,052.

To all whom it may concern:

Be it known that I, FRANK A. STRoDEL, a citizen of the United States, residing at Syracuse, in the county of Onondaga and State of New York, have invented new and useful Improvements in Drawing-Board Holders, of which the following is a specification.

This invention relates to drawing board holders, the object in View being to provide a convenient and adjustable device whereby a drawing board may be supported or held in fixed relation to a table, desk, work bench or the like and adjusted as to its inclination or, in other words, tilted at any desired angle and also shifted so as to overlie the table, desk or the like more or less as may be desired.

A further object of the invention is to provide a holder adapted to drawing boards of different sizes and thicknesses and also adaptedto table or desk tops and the like of varying thickness; also means for firmly clamping the drawing board to the holder; also an instrument holder to be used in conjunction with the drawing board and holder therefor.

With the above and other objects in view, the invention consists in the novel construction, combination and arrangement of parts, as herein described, illustrated and claimed.

In the accompanying drawings Figure l is a perspective view showing a drawing board, partly broken away, and a pair of holders therefor.

Fig. 2 is a vertical section taken adjacent to one of the holders and showing the drawing board in section.

Fig. 3 is a similar view showing another form of board supporting rod.

Fig. 4i is a cross section in line with the thumb screws, showing the means for tiltin and adjusting the supporting rods.

ig. 5 is a fragmentary section showing the board and instrument rack clamped.

Fig. 6 is a view partly in side elevation and partly in section showing modified holding means for the drawing board and a modified form of implement holder.

Fig. 7 is an enlarged fragmentary perspective view showing the holding and clamping means for the drawing board embodying the same construction as shown 1n Fig. 6.

Fig. 8 is a fragmentary sectional view taken in line with the clamping bolts of the quadrant.

Fig. 9 is a fragmentary perspective View of the-modified form of implement holder.

Fig. 10 is an elevation of the two clamping arms of Figs. 6 and 7.

Referring to the drawings, 1 designates the body of a bench clamp, comprising a lower arm 2 and an upper arm 3, one of said arms being equipped with a threaded clamping screw 4: having a thumb piece 5 at one end and having a ball and socket connection at 6 with a clamping head 7, enabling the clamp as a whole to be securely fastened to the top of a table, desk, bench or the like and to accommodate diflerent thicknesses of such a top.

The clamp is provided with another arm 8 extending obliquely wit-h relation to the main body of the clamp and formed at its extremity with a hole to receive a clamping bolt 9 which also passes through a quadrant 10 and forms a pivotal connection between the quadrant 10 and the arm 8. The bolt 9 also passes through a clamping jaw 11 which is movable in relation to another jaw 12 formed integrally with the quadrant, the inner faces of said jaws being concavcd or grooved to receive a drawing board sup porting rod 13 of any suitable length. A winged nut 14 is threaded on the bolt 9 and by loosening said nut the rod 10 may be adjusted in the direction of its length to give more or less overhang to the drawing board in relation to the table or bench to which the device is attached.

The quadrant is provided with an arouate slot 15 which receives a clamping bolt 16 inserted through the arm 8 and provided with a winged nut 17 threaded thereon. A washer plate 18 is provided with holes to receive the two clamping bolts above referred to and to prevent the nuts on said bolts from turning when the quadrant is swung on its pivotal connection with the arm 8 of the clamp.

Under the preferred embodiment of this invention, the rod 13 is provided at the end farthest from the draftsman with an L- shaped arm 19 having a board clamping member in the form of a screw 20 threaded through the same, said screw being provided at its lower end with a cup-shaped clamping head 21 which is journaled on the end of the clamping screw. Under another embodimentof the invention, the, rod, 13 is provided at the end next to the draftsman with an L-shaped arm or hook 2 against which the lower or adjacent edge of the drawing board rests, to preventthe drawing board from sliding off the rods 13 when the latter are inclined. The drawing board is indicated at 28, and the hooked end of the arm 22 forms a board clamping member by. turning the rod 13.

24 designates an instrument rack shown in the form of a metal strip, L-shape in cross section and of sufficient length to reach holders may be securely-fastenedtothe topof a table, desk or bench or the like at a suitable distanee apart to TGCQIVO 'a drawing board of a given size. The board'is then laid upon the supportingrods 13 andsecurely clamped thereon by themcans described. At thesame time the instrument rack orholder may be clamped upon the board so as to extend along the edgethereof farthest from th draftsman. By loosening the winged nuts above referred to, the quadrants 10 may be turned ontheir pivotal connection so-as to give greater-or less inclination to the drawing board and the supporting rods 13"and may be clamped at any desiredinclination by again tightening said nuts." Furthermore, by the same means, the board may be given more or less overhang in relation to *the supporting bench or table by adjusting the rods 13 in the direction of their length in relation to the jaws by which they are normally held in fixed relation to the quadrants.

Instead'of employing the holding and clamping member or arm 22 hereinabove described and illustrated in Fig-3, :a pair of such arms may be employed,said arms being indicated at 25 in Figs. 6, 7 and 10. The arms 25 are provided with knuckles 26 and 27 which overlap each other and arebored to receive the adjacent end ofthe rod 13 on which the-drawing board- A is placed. A coiled spring 28 encircles the rodql3 between one ofthe knuckles 27 and the knuckle 26 and the opposite extremities ofsaid spring,

one of which isshown at-29, bear against theupper or adjacent sides of the arms 25 so as to force the free ends of the arms into engagement with the top surface of the drawing board as clearly shown in Figsp6 and-m7 said arms beinglL-shaped as shown and provided at their overhanging extremities with enlargements or knobs 30 forming board clamping members to impart better holding qualities thereto. Before placing the board on the rod 13, the free ends of the, arms 25 are moved toward each other so as to admit the board beneath the knobs 30.

. The arms-25 are then released and the spring 28 forces the knobs 30 tightly against the board as well as any drawing paper or sheet placed lLllGIBOIla As shown in Fig. 8, the washer plate 18 may be dispensed with by reversing thebolts -9 and 16 so thatthe-head= of the bolt 9. will bear against the movablenjaw; l1 and the head of the-bolt 16 will bear-directly against the quadrant. The Winged nuts 14 and- 17 will-thenbe arranged at the opposite side of the arnrS and by placing- -a bushing 31 around the bolt- 9, the quadrant 10f may be adjusted by merely loosening the thumb nut 17.

Instead of the implement holder=2 l hereinabove described,-I may employ the implement I holder illustrated in Figs. i 6 and-9, the same'being L' shaped as previously indicated but being provided with key holeslots-32 to receive headed screws 83,enabling-the implementholderto be readily attached-to and'detached from the drawing board'without manipulating the clampmgscrews-of thetconstruction previously described.

Having thus describedmy invention, 1 claim r 1. A drawing board holder embodyi ngza clamp adapted to be fastened to a horizontal support, anarm extending from said elamp,

' a quadrant pivotally mounted on said arm,

fixed and moi able aws on said quad-rant, a board supportingrod adapted to be partially rotated and clamped betweensaid j awsand adjustable in the direction of its length, a clamping bolt passing transversely through said jaws, means *-forclamping the quad-- rant .at any 'pOlll-l'rlll tlle pivotal movement thereof, and board clamping means on the upper end of said rod.

2. A drawing board-holderembodying, a V

clamp adapted to'be-fastened tea-horizontal support, an arm extending from said clamp, a quadrant pivotally mounted on said arm, fixed and movable jaws onsaid quadrantf a board supporting rod adapted to be partially rotated and clamped between-said jaws andadjustable inthe direction of its length, a

clamping bolt passing transversely through I said jaws, and means'for clamping the quadrant atany point in'rthe pivotal movement thereof, said supporting rod being provided" at its-upper 'endwith' an L-shaped board- 'holding arm and clamp. i

3. A drawing board holder embodying a clamp adapted to be fastened to a horizontal support, an arm'extendi-ng from said clamp,

a quadrant pivotally mounted on said arm, fixed and movable jaws on said quadrant, a board supporting rod adapted to be partially rotated and clamped between said aws and adjustable in the direction of its length, a clamping bolt passing transversely through said j aws means for clamping the quadrant at any point in the pivotal movement thereof, an L-shaped arm on one end of said rod to overhang the upper edge of the drawing 10 board, and a board-clamping member carried by the last named arm.

In testimony Wherof I afiix my signature in presence of two witnesses.
