DRAWING-BOARD.
Specification of Letters Patent.
Patented Aug. 8, 1905.
Application filed February 12, 1904. Renewed June 30, 1905. Serial No. 267,850.
To (LZZ whom it may concern.-
Be it known that I, WILLIE L. E. KEUFFEL,
a citizen of the United States, and a resident of of soft wood in order to receive the thumb-- tacks with which the paper secured on them is fastened down. They are generally used also where there is plenty of sunlight, and the heat of the suns rays affect them as described. Dovetailed battens have been employed to stiffen such boards, and battens have also been directly screwed or nailed to their under surface for the same purpose. It is a matter of experience, however, that battens so secured do not actually prevent warping and when it does occur are not provided with means to remedy such condition and sometimes by their own warping distort the board.
The object of my invention is to provide a drawing-board with battens which will be at least as eflicient as those now commonly employed and which can in addition be readjusted to remedy a distortion of the board due to warping, if it does occur.
In brief, the invention consists in providing a drawing-board with battens and means for securing them in place, which may be arranged in a new manner and readjusted to straighten the board if distorted.
In the drawings, Figure 1 is a bottom plan view of a portion of a drawing-board provided with my improved invention. Fig. 2
' is a sectional view, with parts in elevation, of
aportion of my improved drawing-board; and Fig. 3 is a section on the plane of the line 3 3 in Fig. 1.
In the drawings, 10 is a drawing-board of usual form and material, the grain of the wood running from left to right when it is in the position shown in the views presented.
20 is a batten, of which there may be several, placed as the size of the board may require. These battens are preferably made of hardwood with the grain running trans- Versely to the grain of the wood in the board.
They may be made of metal, however, without departing from the principle of the invention. Each batten has a broad bearing surface adapted to rest-against and bear upon the under surface of the board 10 and is provided along its length on each side with a flange 21 21.
3O 30 are bearing-plates, each comprisinga body provided at one end with an upwardly and inwardly extending angular flange 31 and at the other end with a downwardlyextending angular flange 32, which engages the board, and said body also has an aperture adapted to receive a screw 40, which is turned into the Wood and the head of which rests on top of the flange. These plates are preferably made of metal. The flange 32 has the function of imparting to them an element of elasticity by lifting the main body of the plate a short distance from the surface of the wood, and thus enables the flange 31 to be brought properly into engagement with the flange of the batten when the wood has shrunk or when the parts are not nicely fitted one to another.
When the parts are assembled, the battens 20 are arranged in suitable position and the plates 30 30 are arranged at any distances apart which may be desirable, the flanges 31 31 extending within and engaging with the flange 21. The screws 40 40 are placed in position and turned into the board 10. When thus assembled, the battens will ordinarily keep the board from warping for some time. If, however, warping does occur, the screws 4.0 40 are loosened, the plates 30 30 are slid along the flanges 21 21 until in proper position near the place where the distortion has occurred, and the screws are again tightened. This brings the distorted or warped portion of the board home against the batten, straightens it out, and makes the board flat and again serviceable. Such readjustment may be made as often as necessary-that is, this construction permits the contraction and expansion of the board and at the same time will keep it tight against the batten.
What I claim as new is- 1. A drawing-board provided with a batten having a longitudinal flange and means for securing said batten to said board, comprising a plate having at one end a flange which engages the flange of the batten and at its other end a supporting-flange which extends at an angle with the body portion of the plate and engages the surface of the board and supports said body portion in position elevated above said board and normally approximately parallel with said board, said body being adapted to be drawn into position inclined toward the surface of said board from its said supporting-flange, and means for securing the plate removably to said board, substantially as described and for the purposes specified.
2. A drawing-board provided with a batten having a longitudinal flange, a plurality of l'lolding-plates each comprising a body, having at one end an angular flange the free end of which engages the flange of the batten and at its other end a flange which engages the board and is adapted to support said body out of contact with the surface of the board, and means extending through said body for securing the plate to the board.
3. A drawing-board provided with a batten having its. grain running transversely to the grain of the wood in the board, said batten having longitudinal flanges, and means for securing said batten removably to the board, comprising a plurality of holding-plates each having a main body, provided at one end with a flange which engages the flange of said batten and at its other end with a flange which engages the board and supports the body yieldably upon the board, and means extending through said body for securing the plate removably to the board.
l/Vitness my hand this 11th day of February, 1904:, at the city of New York, in the county and State of New York.
