To all whom it may concern:

Be it known that I, JOHN MARKWIOK, a

citizen of the United States, residing at De trolt, 1n the county of Wayne and State of Mlchigan, have invented certainnew' and useful Improvements in Childrens' Furniture; and I do declare the following to be a full, clear, and exact description of the in vention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention has for its object to provide an article of furniture for childrens use, embodying a chalr, a table, a receptaclefor toys, and a hinged cover for such receptacle forming a black boardwhich may be heldin numerous inclined positions. r

WVith the foregoing general object in view the invention resides in the novel features of construction and unique arrangement of parts hereinafter fully described, claimed and illustrated in the accompanying drawin s:-

igure 1 is a perspective view of the device in position for use as a chair.

Fig. 2 is a perspective showing the chair seat opened to form part of the table top and illustrating the black board raised to an in clined position.

Fig. 3 is a transverse section with the black board positioned as seen in Fig. 2.

Fig. 4 is a view similar to Fig. 3, but illustrating a position of the board and its holding means intermediate the maximum opened and closed positions.

Fig. 5 is a fragmentary top plan.

Fig. 6 is a diagram to illustrate more clearly the operation of the supporting means of the black board.

In the drawings above briefly described, the numeral 1 designates a box having legs 2 at its corners, said box being provided with a top 3 hingedly mounted at one edge upon trunnions or the like 4, the upper side of said top forming a black board as indicated by the heavy shading 5 in Fig. 5. Suitable provision 6 is made at the edge of the top 3 opposite the hinges, for easily opening the device when required.

An ear 7 extends inwardly from the side of the box 1 opposite the hinges of the top 3 and at 8, the lower end of a link 9 is pivoted to said ear, the upper end of said link being pivotally connected to the lower end of a second link 10, the upper end of said last named link being pivoted at 11 to an ear l2'depending from the top 3. The pivotal connectionbetween the links 9 and 10 consists of a bolt 13 and a thumb nut 14 threaded thereon,said thumb nutbeing of'such size and proportions as to form'a weight for a purpose to appear. Also, after the top 3 has been raised to the desired angle, tightening of the nut 14 will clamp the links 9 and 10 togetherto hold said top in the required position- By the provision of the weighted nut 14 or other suitable weight at the pivotally connected ends of the links9 and 10, the device may be much more easily operatedthan could otherwise be done. For instance (see F 1g. 6) the weight 14 is disposed at approximately thepoint B when the top 3 is closed.

Whenit isrequired to open the top, it is quickly raised with the result that the weight 14 in'moving from the point B to the point C, gathers suflicient momentum to move the.

links beyond dead center to the position seen in Fig. 3, the weight 14 being then located at the point A of Fig; 6. By this op eration, it is not necessary to hold the top 3 raised with one' hand and to operatively position the links 9 and 10 with the other. When loweringthe top 3 said top is first I raised so that'the weight 14 moves from the point A to the point C of Fig. 6. Gravity then acts upon such weight so that it will properly fold the links 9 and 10 as the cover 3Q descends. In most cases, the arrangement is such as to locate the black board at a convenient angle whenthe link 9 rests upon the edge of the box 1 as seen in Fig. 3, and it is A not therefore necessary to tighten the nut 14.

If other angular positions of the board are desired, however, the nut in question may be tightened to so clamp the links together as to hold'such board in place.

A chair seat .15 is hinged at 16 to the upper edge of box 1, the hinge axis of said seat extending at right angles to the corresponding axis of the top 3. The seat 15 is provided with a chair back 17 and with arms 18, and when the parts stand as seen in Fig. 1 with the seat 15 resting on the top 3, hooks 19 are employed to securethe several parts in operative relation so that the article of furniture forms a childs chair. When the chair seat 15 is swung into the position in Fig. 2, a table is provided, the stiles 20 of the chair back 17 then forming two legs of the table. The box top 3 may be swung upwardly and used as a black board while the terial, models, sketch books, etc. The box 1 forms a desirable container for toys in addition to performing its other functions.

From the foregoing, taken in connection with the accompanying drawings, it will be seen that I have provided an extremely simple and inexpensive article of furniture, also one of which will be highly desirable, afiording a great deal of amusement for children, as well as providing a desirable receptacle for toys.

I claim 1. An article of furniture comprising a body member, a blackboard hinged to the upper part of said body member for downward folding thereon and for upward swinging to an inclined position for use, means for holding said blackboard in inclined position, an extension board hinged to said body member on an axis at right angles to the hinge axis of said blackboard and adapted first to fold downwardly on said blackboard when not in use, second to be swung outwardly into a horizontal position for coaction with said blackboard in form ing a table when said blackboard is folded downwardly, and third to support drawing material when said blackboard is inclined for use, and leg means for said extension board to support it in a horizontal position when extended.

2. A receptacle comprising a box having a hinged top adapted to swing upwardly, and means for holding said top in an inclined position, consisting of a link pivoted at its lower end tothe side of said box opposite the hinge line of said top, said link be- 'the free edge of said top, and a weight mounted on the connected ends of said links for operatively and inoperatively positioning them when said top is opened and closed, respectively. i

3. A receptacle comprising a box having a' hinged top adapted to swing upwardly, and means for holding said top in an inclined position, consisting of a link pivoted at its lower end to the side of said box opposite the hinge line of said top, said link being adapted to swing outwardly to an inclined position and to then rest against said side of the box, a second link pivoted at its upper end to the free edge of said top, a boltpivoting the lower end of the second named link to the upper end of said first named link, and a combined weight and thumb nut threaded on said bolt for clamping the two links together and for operatively and inoperatively positioning said links when the top is opened and closed, respectively.-

In testimony whereof I have hereunto set my hand.

JOHN MARKWICK.
