My invention relates to irnprovements in [paper holders which have clamps with th n convex head's, said-heads are made to press down upon and hold .the corners "or edges oia sheet of paper fiat against aib'oard, The stems of the clamps are'held by nuts" and springs within cylindrical shaped housings, said housings being inserted a press' fitin holes in the board. "The topsjo'f the housings being even with the/top ofthe board. The
heads of the clamps when mjoved'by'the fiagers slide around in a circle and over 1n- "clin'ed .camswhich are upon the tops of the housings; and drop "ofi the ends off said canisupon the corners of the sheet ofgpaper.
The clamps have sharp edges on the ends which the aid of the springs pinch the v corners tight enough to holdthe sheetfin place while drawing and'when 'said drawing is complete said sheet Inay'be released "by sliding thehe'ads of said clamps around and ofi" the corners. i I
The objects of improvements are:
' First, to provide a quick and easy'relea's ing paper" holder for standard drawlng sheets such as. are now used in pu dlic'schools certain drafting-rooms. v
Second, to provide a clamp fOI l10ld111g drawing paper and sketch paper in place while drawing :and said clamp to remainir' position inserte din adrawi-ng board forf'a's many drawings as desired without removing said clamp. Z 9
Third, to providea suitable device to take the place of the common thumb tack, one which wilhnet have to be pressed inand taken out for each drawing. I I
' Fourth, to provide a suitable device 01 clamping each corner of a standard sheet of paperin the same place on a flat smooth surraceand quickly releasing each corner when work on the sheet is complete. H
I attain these objects by th'e mechanlsni illustrated the accompanying drawing in inserted within a piece of board and the parts which .are exposed.

p The h o'llow cylindrical housing 1 is Jinserted a press fit into- ,a hole 22 bored in or :through the drawing-board '2 .and .made to come flush with its top surface, with the cam portion {of said housing protruding above said "board :as shown .at 1 .in sefition of Fig.2. The clamp 3 has .a threaded stem 4 which slip .fitnin the .hole h of the housingjl "Within the cylindricalfhousing 1 a ballsbearingf67-8 is .mad'egalslip fit over the stem 4 which 'helps clamp 8 to revolve easily around the circle 20 shownlin Fig. 1. dThis ball-bearing '67-.8 is pressed up against 'thefinner ,part ofthe housing, 1! by a shortspring 9. VVhenthe ,lock vnuts 10 ,11fare'fadjnsted tight enoughonrthe stem ilth'ey "press the spring"9 against the ballbearing 6%7 '8 and force the. sharpedgef12 of the clamp3 against the sheet 1 of paper 13.011 theboard'Q. Wheni'takingthe sheet of paperil3 o'fl? the board2 theclamp .8 is 'f fo'rced to revolve by the .finger pressed against its edge untilitcome's to thegposi- %tion 14 as; shown inFigl. Whengplacing the sheet otfpaper under the clamp?) the cornerfo'f fsai'd "sheet is} placed in position [as shown at 15 in Fig. i lj and clamp I3 ,is forced in the "direction indicated by the arrows 16 1 over the 'ca'in 17 until said clamp '3 drops-off the edge 18. The spring 9 is adjusted tight enough to force the sharp edge 12against the paper 13 so that itremains in position until the required drawing is complete. The
cam 17 Y is a .pressed inclined ridge in the sheet metal housing 1, and starts even with the top at 19v ofsaid housing and circles around hole 5, and slopes upward to the end 155, The clamp 2; when moved around by the finger drops 013? the end 18 and down upon the corneroi the sheet of paper as shown in Fig. I. Said cam 17 may be made to swing around hole 5 in either direction by making the incline either right hand or left hand as desired. Flange 21 and nut 23 will prevent the housing 1 from coming loose in the hole Having described my invention, What I claim as new and desire to secure by Letters Patent is:
1. A paper holder for drawing boards comprising a cylindrical housing open at one end and partially closed at the other and being of a length sufiicient to extend through the thickness of the board in connection with which it is to be used, a cam on the partially closed end of said cylinder, an L-shaped lever extending through said cylinder and having one end vthereof arranged to ride over said cam, a spring in said cylinder and surrounding one end-of said lever for holding said lever in its lowermost position,and means for retaining said spring in operative position.
2. A paper holder for fastening paper to a. drawing-board, comprising a cylindrical housing open at one end and partially closed at the other, with a flange on said partially closed end, an inclined cam on top of said housing made to curve a part of the way around the hole on top of the partially closed end, an L-shaped clamp extending through said hole, having one end bent to extend over the top of said cylindrical housing, the other end having a coil spring around the shaft portion which extends within said cylindrical housing andmeans for retaining said shaft and spring within said housing and in operative position.
3. A .paper holder for drawing boards comprising a cylindrical housing open at one end and partially closed at the other, with a flange around the partially closed end thereby keeping the top of said housing flush with the top of said drawing board for which it is to be used, and said housing containing an L-shaped clamp with a flattened end bent at right angles to a round stem,'said stem being inserted through a hole in the partially closed end of said housing, around said stem and within said housing a spring being coiled and held on said stem by two nuts said nuts being adapted to hold said stem, to vary the tension on said spring and the grip on said clamp, a cam on the top of the partially closed end of said housing means-for ra1sing said clamp sufficiently" high enough above the surface of said drawing board and the top of said housing to clear the paper for which it is adapted toclamp.
4. A paper holder for drawing boards comprising a cylindrical housing open at the bottom and partially closed at thetop, an incline cam on the top of said cylindrical housing and which curves around the hole in said top, said housing containing an L-shaped clamp with one end bent at right angles to the stem which. is made to fit into the hole in the top of said cylindrical housing, within said housing and over said stem there being a spring which is held in place by a. nut forming means for keeping a pressure on the bent portion of said clamp head and pinch the corner of the drawing paper which it is intended to clamp and hold.
5. A paper holder for drawing boards comprising a 7 housing adapted to be mounted in a drawing board, a 'reciprocable and rotatable member in said housing provided with an overhanging paper engaging end, means in said housing adapted for holding said member in a retracted paper engaging position, and means adjacent the overhanging paper engaging end of said member upon which said member is adapted to be turned to raise it out of engagement with the paper.
6. A paper holder as called for in claim 5, wherein the last mentioned means is carried by said housing and has the configuration of an arcuated cam.
7. The combination with a drawing board upon which paper is adapted to be mounted, of a housing mounted in the drawing board with its inner end substantially flush with the lower face, of the drawing board, a reciprocatable and rotatable spring held paper engaging member supported from said housing and adapted to exert pressure on a sheet of paper adjacent said housing for vholding the paper on said board, and means in the arcuate path of said member adapted for raising said member when r0- tated to release the sheet of paper relative to said board.
In testimony whereof I have hereunto set my hand this 2nd day of December, 1924:.
