Letters Patent No. 111,230, dated January 24, 1871.

IMPROVEMENT I N FOLDING DESKS.

The Schedule referredto in these Letters Patent and making part o'f the same.

To all whom it may concern v Be it known that I, JOHN MILWAIN, of Nashville, in the county of Davidson and State of Tennessee, have invented a new and'improved Folding Desk; `and I do'hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the' same, reference being had to the accompanying draw' ing forming part of this specification. i

This invention relates to improvements in folding school-desks; and

It consists, in a combination with the folding table of the desk, of -strip or yplate for closing the opening at the joint where the table is folded down, and an arrangement of 'the pivotjoints, bracing arms, and

. guide-grooves for the latter, for operating the table so -as to-etfect the said closing of the joint, so that, when the table is folded down, theiback case beneath, will be closed dust proof.

v Figure 1 is an end elevation I of' my improved fold-` ing'desk 5 'Figure 2 is a 'sectional elevation ofthe same, taken on the line a: x of iig. 3; and

Figure 3 is a 'side elevation. l Similar-letters of reference indicate corresponding parts. v

A is the joint-closing plate or strip attached totlie desk-table B, atthe edge next` the joint, and under side, so as to project a onsiderabledist'ance from the said edge under the top C when the table is raised'. The object of this is to swing, 'when the table is let down, against the 'under side of thev top C, so that the cased) foi' the books will be closed dust proof, the `table covering the openings E into said case, and the the vertically-elongated slots in strip Athe opening caused by-the 'swinging of the edge of the table away from the-edge of the top C.

In order to arrange the pivots andthe bearings therefor so that the table may he worked with this 'attachment and he adjusted snugly against thev edge of' the top O when raised up, and also allow the table to fold down against ,the edges F of the end supports G., I have: provided the vertically-elongated holes H in thc said end supports, to allow the pivots L'mounted 4table is up, to afford them permanent seats, wherein they are held by the locking-pawls P, which bear against then for the purpose when in the said seats, and are lifted away tolet them escape from the seats to let the table fall.

Having thus described my invention,

I claim as new and desire to secure hy Letters Pat-` ent-' llie table or leaf B, -provided with the strip A, and attached to the bracket K, having pivots working in he frame, substantially as and for the purpose specified..
