To all who mit may concern Be it known that I, INnz Gnnvns, citizen'of the United States, residing. at Seattle, in the 7 county of King and Stateyof WVashin'gton,

have invented new and useful Improvements inlroiiingBoards, of which the. following is a specification. f The object of the invention 1s to prov de in combination with an lronlng board an appropriate standv therefor, the stand compris ing a leg or support element hingedlyi attached to the board and operativelyconnected with a clamping member also attached in use may be placed in a cupboard out of the way where it does not take up much room because of parts connected therewith lying to the board but desi upon the edge of a tab ned to effect af'grip Te or shelf, so thatthe latter acts as one support of the board while. f the'leg or support member acts as the. other. The-leg member referred to'is adapted for folding down against the board when not in use and when thus folded relieves the clamping member so that the grip exerted by the latter is released. Thus the board when not close to the board when iin inoperative position. z z

The further object of the'invention isto provide a sleeve board which is'mounted on the main board in such away that it may be readily detached therefrom or swungto;

a position where-it is out of the way when the main board is in use. j A still further object is to; provide ina device of this character a construction which is simple in design;v durable and effective in operation and inexpensive. to manufacture.

Other further objects'appear in the following description wherein the invention is set forth in detail. To the exact construction in which it is shown and described the invention is not to be restricted. reserved to make such changes or alteration as the actual reduction to practice may suggest, in so far as such changes or alterations are compatible in spirit with the annexed claim. .7

board 8 and appropriateimeans by which the I a 'mainboard can be clamped .torthetablel at one end andsupported at an intermediate point between the table and the other end( j On the bottom of the main'board .2 there I is attached acrossbar fw'hich is recessed on Y the end face-as at 5, the bottoms; of. the re- 'cesses being slightly inclined in. the c direction of'the rear-end oftheiboard. Cla1mping plates' 6 are secured to the cross barv 4 and lie in the recesses 5, being secured tobart-and 1 to th'eboard bymeansof bolts 7 whichreceive I wing nuts on their lower-ends, thewing nuts abutting the bottom faces of the clamping plates 6. The bolts 7 pass through the clamp platesand the holes through which they pass are obviously of such adiameter that a slightrocking movement will be permitted the clamp plates, the forward extremities of whichare adapted for clamp engagement,

of theunder face withthe top of the table board the plates with thetable top is not possible,

the inclined bottoms of therecesses 5permitlaadjacent the edge, theforward end fthe,

lying on the top of the table when the i v V offthe plates I: 6 are depressed, a firmclamp engagementof ting the rear ends of the clamp plates to in 'cline fo rwardand thus relieve .the'forward ends of these platesfr'omcla'mp engagement I with the table top. I Means is provi'ded, howclamp plates, the two of which. are intercona ever, for .depressing'the rear ends of the ne'cted {bya crossbar 9-{adjacent theirrear-Q ends. 'The;means referred to comprises a leg 10 having a crossbar 11 attached to the upper end thereof-and this legand its cross barare mounted on the board 2 on the under face thereof, a hinge l2 effecting this attachment of the leg and its attendant cross bar to the board. The hinge is so mounted that the leg may swing to a Vertical position with reference to the board when the upper edge of the cross bar abuts the under face ofthe board. The leg is thus precluded from movement beyond this .position but maybe swung back against the board when its lower end rises adjacent the re'ariend of the board. In swinging the leg inthe vertical position'referred to, the cross bar 12 is brought into contact with the upper faces of the rear ends of the plates 6, thereby depressing them, since the width of the cross bar 11 is greater than the thickness thereof. Hence a clamping engagement with thetop ofthc table 1 iseffected the board had prezviouslybeen laid on topof the table to per- 'mit the forward ends of the clamp plates r to lie beneath the top. i

cvice readily engage the edge ofthe" table initially. To this end a spring 13 is employ eds this springhaving one end secured to a preferably wide member'l l which is connected to-the two plates 6, as shown.

- The remaining end of this spring connects with wire strand 15 formed with'an eye ateachend with one of which the end of the spring 14 connects, the other end serving as the meansfor securing the-strand to the under face" of the board by means of a screw or other fastening device 16. T he'strand 15' isattach ed to the hoard'between the, cross bar i1 and the rear end of the board but it extends to the'forward of the cross bar and i above the latter to receive the end of the spring 13. The movement of the leg 10 then to a perpendicular position with refer,- enee to the board serves to clamp the strand between the cross bar 11 and theboai'dand in so doing throws the end ofthe spring closer to the board, thereby increasing the tension on the spring." "Thus when the leg 10 is: folded down against the-hoard, the point of connection betwcenthe spring and" the strand may'more nearly aline itself with the point of connection between the spring and the'member 14 and the point of'conn'ection between the strand andthe board when the-tensionon'the spring is obviously re- ""du'ce'd. 1 This'arra'ngementmakes forthe reductionof-the tiring efiect on the spring,

thus serving tokeep it active and to increase 1 its tension when the'leg' 10 is turned downg'j when the increased tension causes the rear ends of the plates 6 to effectively and firnily' clamp the'cross bar 11 and to hold it in a position where-it retains the leg 10in vertical position.

'. The'sleeve board 3 is carried by a Z-shaped o arm 17 one extremity of which is threaded toreceive a wing nut 18, this threadedportion of the Z-shaped member passing through [an "appropriate'hole'formed inQthe board 2, the Z-shaped member lying against the board.

2 on the upper face andthe wingn'ut "aljuta r ting the board 2 onthe bottom .i'aceL This sleeve board may readily 'be' removed from" the main" board if desired by detaching the wing nut 18 and maybe moved out offthe wayeven when attached to the board 2,"it

being swung around on the'threaded portion as a pivot to a position where it practically" leaves themain board 2 freefor use.

From foregoing description and"the"ac- V companyi-ng drawings itis believed'tha-t' a clear enou-ghiunderstanding of the inven tl'onis to be hadto render furtherfdescriptron of the invention unnecessary,

The invention having been described,w'hat is claimed as newjand useful is:

A household article of the kind 'described'.
